This is an ongoing project, focusing on offering choice and control in elephants’ environments to investigate preferences around audition and design aesthetics.

Maybe you don't trust a cloud-hosted service with your highly classified information, or perhaps you like to build things for yourself. In this light-hearted talk, you will learn how to make a real-time on-device GenAI-powered application that can live transcribe and summarize conversations without internet access, using open-source components. Our journey begins with an introduction to open-source LLMs and the latest trends in running GenAI tools on your own hardware. We will build up our application step-by-step, first creating a live streaming voice-to-text transcription pipeline, then an LLM-based conversation summarization layer, presented within a Streamlit frontend, with conversation summaries sent to a lightweight Django API backend for storage. Here's why this matters: 1️⃣ Cloud-hosted SaaS tools cannot store highly sensitive information. 2️⃣ Good open-source alternatives exist for most GenAI tasks; the more people who use them, the more they will thrive. 3️⃣ Commercial tools will solve for common use cases, but developers can build personalised tools that are highly specialised for their own bespoke needs. This talk is tailored for Python enthusiasts and requires no ML expertise. By seeing a practical demo come together piece by piece, attendees will gain a deeper understanding of how to build their own complex Generative AI applications and be pushed to imagine what they could make for themselves using on-device computation in real-world scenarios. Expect plenty of Python code and some fun live demos, with GitHub code provided for attendees to try it at home.

Conditions are often wet, muddy and involve confined spaces. This talk will look at how the technology we have developed has changed how we measure and create maps of cave systems. From traditional sighting compasses, tape measures and paper and pencil, to laser measures, bluetooth data transfer and PDAs or mobile phones as recording and drawing devices. Then once the data is collected underground, how open source software has been developed by cavers to process the data and draw maps which adjust to later changes in positions of parts of the cave when more data is collected or corrected. We'll look at loop closures, explorations of places no person has gone before, and different ways to present a 3 dimensional map of a 70km cave system. There will be plenty of photographs and video clips of cave exploration, along with live software demos and viewing of digital maps.

Artists and their shows constantly seek the latest lighting & video technology, intricate stage setups, and top-notch audio quality to dazzle fans. Ticket sales are a major revenue stream for Artists, and a high-quality production show, sells tickets. This high level of production is only possible because of an industry full of talented roadies. Behind every arena or stadium show lies a hundreads of engineers tirelessly setting up, operating, and dismantling these elaborate stage setups, often in a new venue, on a daily basis. Long gone are the days of makeshift equipment cobbled together, roadies now navigate highly sophisticated AV control systems supported by intricate network infrastructures. A vast array of specialised hardware caters specifically to live events, engineered to be both flexible for on-the-fly adjustments and durable for daily setup and teardown. Reliability is paramount, with equipment expected to perform flawlessly show after show, never missing a beat. In this talk we are going to take an overview into the world of live event production, shedding light on how roadies consistently deliver stellar performances day in and day out. We'll explore the intricacies of AV networks, offering an insightful overview of the behind-the-scenes magic that brings unforgettable concerts to life.

Have any questions you want answered? Email them to will.furnell@stfc.ac.uk Boulby is one of just a select few facilities in the world suitable for hosting ultra-low background and deep underground science projects. It is a special place for science, 'a quiet place in the Universe', where studies can be carried out almost entirely free of interference from natural background radiation. It also provides access & support for studies of the geologically interesting deep underground environment.

The guitar is built using no less than 4 different types of 3D-printing, including 3D-printed aluminium. At the same time it sticks with traditional hand built woodwork for the playing surface, matching material with function. This talk will focus on the design behind the guitar, looking at what you can do with generative design and 3D-printing, how to interface the old and new construction techniques (e.g., mating a walnut body with 3D-printed nylon sides), and how to decide what bits to do with which technique. I'll also show how I achieved this as an amateur maker: the aim is to show the audience that what seems like far-out construction is actually reachable by us mortals thanks to improvements in tooling and 3D-printing services.

The guitar is built using no less than 4 different types of 3D-printing, including 3D-printed aluminium. At the same time it sticks with traditional hand built woodwork for the playing surface, matching material with function. This talk will focus on the design behind the guitar, looking at what you can do with generative design and 3D-printing, how to interface the old and new construction techniques (e.g., mating a walnut body with 3D-printed nylon sides), and how to decide what bits to do with which technique.

In particular, how are sea mammals coping with such changes in their environment? Do we need to put automatic mitigations in place – is it even possible? For over a year, we have been annotating more than 60 terabytes of data, finding these rare events of interest. We’ve looked at whether Artificial Intelligence, combined with sonar, can automatically spot and classify interesting underwater objects. We’ve tried several approaches, some more successful than others, but there are promising results with movement detection and segmentation. This talk covers our initial findings - where we went wrong and one promising approach that we are still actively researching.

Suddenly little bits of hardware can control all kinds of games and interfaces on screens. And building a UI for your electronics becomes trivial too. This is a talk for anyone who’s ever tinkered with hardware or web design, and wants to join the physical to the digital. During this talk I will explain the basic techniques of keyboard emulation and using the Javascript Web Serial and Web Bluetooth APIs. To make it fun, and introduce some peril, I will demo all of the techniques live: controlling the Google Chrome Dino game by jumping up and down on stage, making a musical instrument from stretchy rubber and allowing audience members to connect to a set of handbells from their phones. Along the way will be plenty of tips on what to buy and what to avoid, I’ll demystify some of the complexity around Bluetooth and USB, and share several ideas for how to use this to cause mischief amongst friends, colleagues and enemies. I have done this before, but only once. Fingers crossed.

You need a high-resolution computer display for fine drawings (e.g. CAD diagrams). Memory's EXPENSIVE, processors are slow: what to do? Here's an analog solution to a digital problem: an unusual cathode-ray tube that preserves whatever it draws with no flickering, fading, or any kind of refresh. A brilliant dot sears emerald trails into the screen, rendering intricate line-art without pixels. No need for video memory when the screen itself remembers! It's mesmerising to see this special tube in action; more satisfying still to know how it works. Discover a mechanism Tektronix refined over three decades, growing from palm-sized oscilloscope readouts to 25" computer-lab behemoths. A wreath of electron guns, kilovolt potentials, microscopic cobalt cones, and transparent anodes set the stage for a nonlinear dance of charges that yields visualisations with style --- and we'll unravel its mysteries with animated diagrams. En route we'll visit notable storage tube applications, from early computer memories to 1978's _Battlestar Galactica_. Of course we'll see a real Tektronix terminal at work, too! Computer memory is cheap now: by the mid 1980s, modern displays had advantages storage-tube systems couldn't overcome.

You need a high-resolution computer display for fine drawings (e.g. CAD diagrams). Memory's EXPENSIVE, processors are slow: what to do? Here's an analog solution to a digital problem: an unusual cathode-ray tube that preserves whatever it draws with no flickering, fading, or any kind of refresh. A brilliant dot sears emerald trails into the screen, rendering intricate line-art without pixels. No need for video memory when the screen itself remembers! It's mesmerising to see this special tube in action; more satisfying still to know how it works. Discover a mechanism Tektronix refined over three decades, growing from palm-sized oscilloscope readouts to 25" computer-lab behemoths. A wreath of electron guns, kilovolt potentials, microscopic cobalt cones, and transparent anodes set the stage for a nonlinear dance of charges that yields visualisations with style --- and we'll unravel its mysteries with animated diagrams. En route we'll visit notable storage tube applications, from early computer memories to 1978's _Battlestar Galactica_. Of course we'll see a real Tektronix terminal at work, too! Computer memory is cheap now: by the mid 1980s, modern displays had advantages storage-tube systems couldn't overcome. Nobody's making them anymore, so check out this talk while old stock still works!

Whether you're for it or (more likely) against it, it's well worth knowing what is actually involved in making it happen and where the real risks are. The presenter recently left a long career in the US oil industry and will give you a view into this world without any spin or agenda and instead give you the opportunity to deepen your understanding of what it's really all about.

Together with students of the UKEN University from Krakow, we decided to look at the use of OSM as a environmental map also showing the transformation of space by humans. The speech is the result of exercises conducted by employees of the Geoinformation Research Team and students of the UKEN University in Krakow, Poland. The basic assumption we made is that OpenStreetMap can be sufficient as a data provider for various geographical works - as a base map for field exercises, as an almost complete environmental database for some compact area (such as an island or a national park). After reviewing the list of tags describing the geographic environment in OSM, we knew this would be possible. We have selected several research polygons, which we call cartographic polygons. These include the Peljesac Peninsula in Croatia, the Aegean Coast near Thessaloniki in Greece, the area around Lake Inari, the Lemenjoki National Park in Finland, and the wild Bieszczady Mountains in Poland. We selected the training fields so that they were both places with nature close to natural conditions and places significantly transformed by human activity. Usually, these were also important places for some key reasons - for example, on the Peljesac Peninsula, a bridge was built to facilitate communication between the two parts of Dalmatia. Not all places were visited, but we have collected cartographic material for all of them. Before each trip, we trained a group of participants on how to use and supplement OSM. Each participant set up their own user account. Field work consisted of completing the content of OpenstreetMap as accurately as possible - groups of two people were sent into the field and, using the OSMAND or EveryDoor applications, they inserted all interesting objects on the map. The rest is small-scale work - tedious verification and editing of the map in the JOSM editor. Each stage of work was also preceded by a thorough analysis of official OSM tags - which constitute information about all elements of the natural environment. It was found that the best represented features were those related to relief, land cover and hydrology. In particular, the content regarding land cover (down to a single tree and bush), and the richness of descriptions of relief forms (OSM WIKI, Glossary of landforms) allow the creation of appropriate thematic maps - landcover maps and geomorphological maps. The principle adopted in JOSM is that we complete the map to the highest degree of accuracy possible using available data and processing capacity. For example, we supplement the terrain coverage for Poland from the available official orthophotomap from the national geoportal with a terrain resolution of 5 cm. The distinction between land cover types is made by students of higher years of geography, so there should not be too many interpretation errors. What information is completed on the map? As for the relief of the land - valleys and valley types, rock walls, erosion undercuts, landslides and landslide niches. When it comes to hydrological elements, using scientific publications, we entered the exact location of the sources (along with a description of water chemistry and name, if this data was available). An additional module of our work is urban micromapping - We check how accurately we can supplement field data so that they can serve two purposes - for students and spatial planning specialists in the analysis and inventory of urban space, and for people with disabilities as a base for accessibility maps used in applications, e.g. blind . For this purpose, we carried out tests of terrain mapping using a geodetic GPS receiver (STONEX 900A). We chose the area on the campus of our university due to the presence of the remains of an old water bed supplying water to mills and a city moat - a lot of unevenness, steps, suddenly ending sidewalks, etc. Additionally, we have also started work on old housing estates in Krakow's Nowa Huta district - inhabited mainly by older people, and therefore often beneficiaries of all programs regarding the availability of public facilities and apartments. Approximately one thousand points were measured in the above locations with an accuracy of 2 mm - 1 cm. In further stages, they will serve as the basis for the point cloud made during unmanned aerial vehicle raids. A number of additional works were also carried out as part of the project, e.g. wild waste dumps in the Ojców National Park were mapped and marked (we will most likely use the tag amenity=waste_dump_site) All work on the project resulted not only in a significant improvement in the quality of the OSM map, but also in the training of a large team who, in their free time, complete OSM data in their area. Both the intimate and field parts of the work are still in progress. We will complete the work by the time of the presentation in Nairobi. This is our beginning in the work of OpenstreetMap, but we would like to use our previous experience in completing OSM data in various places around the world in many task programs, e.g. for UN Mappers and HOT OSM.

Together with students of the UKEN University from Krakow, we decided to look at the use of OSM as a environmental map also showing the transformation of space by humans. The speech is the result of exercises conducted by employees of the Geoinformation Research Team and students of the UKEN University in Krakow, Poland. The basic assumption we made is that OpenStreetMap can be sufficient as a data provider for various geographical works - as a base map for field exercises, as an almost complete environmental database for some compact area (such as an island or a national park). After reviewing the list of tags describing the geographic environment in OSM, we knew this would be possible. We have selected several research polygons, which we call cartographic polygons. These include the Peljesac Peninsula in Croatia, the Aegean Coast near Thessaloniki in Greece, the area around Lake Inari, the Lemenjoki National Park in Finland, and the wild Bieszczady Mountains in Poland. We selected the training fields so that they were both places with nature close to natural conditions and places significantly transformed by human activity. Usually, these were also important places for some key reasons - for example, on the Peljesac Peninsula, a bridge was built to facilitate communication between the two parts of Dalmatia. Not all places were visited, but we have collected cartographic material for all of them. Before each trip, we trained a group of participants on how to use and supplement OSM. Each participant set up their own user account. Field work consisted of completing the content of OpenstreetMap as accurately as possible - groups of two people were sent into the field and, using the OSMAND or EveryDoor applications, they inserted all interesting objects on the map. The rest is small-scale work - tedious verification and editing of the map in the JOSM editor. Each stage of work was also preceded by a thorough analysis of official OSM tags - which constitute information about all elements of the natural environment. It was found that the best represented features were those related to relief, land cover and hydrology. In particular, the content regarding land cover (down to a single tree and bush), and the richness of descriptions of relief forms (OSM WIKI, Glossary of landforms) allow the creation of appropriate thematic maps - landcover maps and geomorphological maps. The principle adopted in JOSM is that we complete the map to the highest degree of accuracy possible using available data and processing capacity. For example, we supplement the terrain coverage for Poland from the available official orthophotomap from the national geoportal with a terrain resolution of 5 cm. The distinction between land cover types is made by students of higher years of geography, so there should not be too many interpretation errors. What information is completed on the map?

INTRODUCTION / BACKGROUND Considering that NGOs and International Organizations have been applying PRA methodologies to community mapping for over two decades without any scientific recognition, we could subscribe to the general opinion that among practitioners, researchers, and activists, the practice of Web-GIS with OSM is more advanced than the underlying theory of its applications [12]. The so-called "digital humanitarianism" can support climate justice by providing tools and platforms for data collection, analysis, and dissemination that empower vulnerable communities to advocate for their rights, mobilize for climate action and advance equitable solutions. Overall, digital humanitarianism can amplify the voices of marginalized communities, enhance transparency and accountability, and promote greater inclusivity in the fight for climate justice. Digital humanitarianism is located at the intersection of new socio-technical practices, a new epistemology, and new institutional relationships [5; 8], as demonstrated by communities like Ushahidi, the Humanitarian OpenStreetMapTeam (HOTOSM), and the Missing Maps. PURPOSE OF THE STUDY The study aims to gain a better understanding of the nature of the link between crowd-mapping and participatory planning by analysing the distinctive features of the application case, the criticalities and problems that emerged, and the possible strategies to be activated to tackle them especially in contexts where people living in rural and remote areas and in peri-urban areas face problems such as inadequate access to essential resources, such as food and water security, and are more exposed to low quality basic services (health and education) and the effects of natural disasters. This fosters inequality, can limit capabilities and promote environmental injustice. METHODOLOGY AND FINDINGS The fieldwork is part of an emergency intervention led by a consortium project combining five NGOs financed by Caritas, with an overall objective of assisting the population impacted by the earthquake that struck in Morocco on September 8 and 9, 2023. As part of this intervention, which calls for various support measures (distribution of family kits, distribution of housing tents and school modules, social-health interventions and psychological support), a humanitarian mapping action is currently being carried out with the help of a group of women belonging to a popular radio station attentive to 'open data'. The project starts from an integrated strategy that brings together humanitarian mapping and future labs, presenting a dynamic approach to addressing social challenges in post-emergency contexts and crisis areas. Case study: the contribution to crowd - mapping experimentation (training, definition of a working group, creation of a virtual mapping environment with the use of OSM and Osmand) is investigated, an ongoing process started by OfficianSocialeCOPE (the Research Centre of COPE ONG) and the University of Catania and Palermo (Italy) within the context of a post-emergence project (which will end in July 2024l supporting the victims of the Earthquake of September 2023 in Morocco with an approach to address the perception of individual and collective vulnerability in a rural post-emergency context. The expected maps are also employed in contrasting contexts, such as in counter-mapping initiatives where indigenous communities (in the case of High Atlas and Sahara villages) seek to regain a certain level of control over ancestral lands and city neighborhoods, resources and services by utilizing participatory mapping methodologies. This makes people aware of their power of pressing issues on local government policies. Localisation of the territorial landmarks reference points takes into account the WEF (Water, Energy, Food) nexus's provided topics, which included access to fresh food, electricity, and water, as well as other issues that the participants perceive as significant to the neighborhood, (watercourses forests, cultivated areas, potholes, etc. in rural areas, but also small income generating activities potentials). More specifically, residents, through PGIS mapping tools for on field visit, report issues such as the level of connection of remote areas with other villages and secondary roads, natural and artificial water sources, soil dryness and exposition to drought in High Atlas, as well as associative realities such as cooperatives or Community Based (CSOs) already established or expressing the will to formalise to create income and revenues. It is critical to consolidate/train the social labs' working groups, which will be made up of territorial representatives and stakeholders from various sectors, such as volunteers, community leaders, and members of local organisations (e.g., muqaddim [neighbourhood or village community leader], kaid [mayor], school teachers, association representatives, headmasters, etc.). Furthermore, the working groups were separated by gender in order to better convey gender-specific demands and requirements. Through the use of GIS tools (QGIS, Google Earth Pro) and a Web map server (OpenStreetMap), and with the classification of the map contributors' working group, future labs are implemented to share experiences and knowledge on mapping activities and their application in the humanitarian context of reference (PHASE 1 and 2), aiming to plan disaster risk reduction and response and propose development processes strategies (PHASE 2 and 3). The final product to stakeholders includes developing a project outcome using a story-map tool (PHASE 3). FINAL DISCUSSION For the first time, in very remote areas of Morocco, the areas and names of settlements, agricultural and productive land and, above all, areas at low and high risk of natural disasters will be mapped with the help of local knowledge. For the purposes of 'spatial learning, discussion, information exchange, analysis, decision-making and advocacy' [11], many approaches and tools will be used 'to represent people's spatial knowledge'. The primary objective will be to learn how community members define vulnerability and to classify various community stressors. The end result that will be presented to stakeholders will be a combination of satellite imagery, GPS survey locations, participatory mapping and spatial analysis of the geographic information system (GIS), combined with information obtained through interviews and field surveys. The development, georeferencing and visualisation of Indigenous Geographic Knowledge (IGK) will help communities to engage in peer-to-peer conversations and ensure that specific issues and concerns are taken into account by the authorities. Only by considering the participatory process itself could the promoted activity become an example of good governance, i.e. transparent and consensus-based decision-making processes for land management. This is why the different geographical viewpoints of women are of particular interest. The article intends to highlight how PGIS can facilitate the creation and exchange of indigenous ecological and spatial knowledge and improve individual social learning regarding the environment and response to natural disasters and promote development. The fact that the case study was developed in a vulnerable context of North Africa is meant to emphasise that in order to help reduce the digital divide, the lack of attention to research and investigation in the field of digital mapping in Africa compared to the significant progress made in industrialised countries must be taken into consideration. Furthermore, it is shown how important it is to evaluate experiences (both failures and successes) and to develop instructions and strategies to promote best practices in this area, ensuring that the reasoned adoption of the PGIS meets the expectations of different groups in developing countries and does not fall into the dynamics whereby the participatory method may underlie systematic inequalities through unequal and superficial use of PGIS applications, which thus risk being used to legitimise decisions already made by other parties.

A systems perspective analysis of the events behind the introduction of rate limiting in OpenStreetMap (sotm2024)</title> <link>https://media.ccc.de/v/state-of-the-map-2024-academic-track-50780-what-happens-when-vgi-is-threatened-a-systems-perspective-analysis-of-the-events-behind-the-introduction-of-rate-limiting-in-openstreetmap</link> <description>This talk presents a systems perspective analysis of events in October-November 2023 which started with large-scale vandalism of OpenStreetMap data in Israel and ended with the introduction of rate limiting. Noting how the project reacted in face of this unique situation and the undermining of its basic assumptions facilitating the project helps uncover resilience- and vulnerability-inducing mechanisms within it, to characterize the range of possible external influences on the project, and assess their possible outcomes. OpenStreetMap (OSM) is generally considered to be a ‘do-ocracy’ [1], a governing system in which power stems from doing and those who do more (contribute more) have greater ability to influence the project. This does not mean that hierarchy within OSM is entirely bottom-up, as Fast & Rimmer’s systems perspective model of a Volunteered Geographic Information project suggests [2] - it is made of interconnected components (the technical infrastructure, project, and contributors) each providing a different level of direct access to the core of the project. Entities may move between these components, but a certain level of separation still exists, enforced informally or formally by gatekeeping procedures or individual acts. The fuzziness of borders and the interdependence of components open for multiple types of interactions that may translate to major impacts on the nature of the project. In this talk we use communication records from various media (the OSM_Israel Telegram group [3], community forum discussions [4,5], and GitHub issues [6,7]) to: i) to analyse a specific set of events - the politically-motivated edits in Israel and the subsequent introduction of rate limiting in OSM [8] - from a systems perspective; and ii) conceptually explore power dynamics and impacts within collaborative geodata projects and specifically OSM along with their implications for the project’s vulnerability and resilience. The chain of events started on 20 October 2023, when two members of the OSM_Israel Telegram group [3] reported receiving offensive comments on their recent edits. One of them noted that the commenting user was performing edits to the OSM data in Israel that were clearly acts of vandalism, i.e. deleting and distorting data. It was only the day after that the members of the Telegram group realised that these acts were part of a greater effort in which 3 newly registered OSM users were performing large-scale deletions and distortions of data in Israel. The timing of these edits, taking place while the Israel Defense Forces were launching airstrikes over Gaza strip in retaliation of the 7 October attack by Hamas, and their related changeset comments, e.g. “There is no country Israel & Free Palestine”, clearly attested that they were politically-motivated (For a representative example, see [9]). The events were quickly reported to the OSM Foundation’s (OSMF) Data Working Group (DWG), the voluntary body responsible for handling data issues such as copyright infringement and vandalism. The DWG issued bans to involved users, yet these were replaced in the next few days by more new users together making tens of thousands of similar edits. Meanwhile, one user, responding to these acts, further vandaled the map by ‘annexing’ part of the Gaza strip [10]. In the immediate aftermath of these events, most of the OSM data for Tel Aviv was deleted from the map and data all across Israel and the eastern Mediterranean basin, as far as Crete, Cyprus, and Turkey, suffered from distortions (the scripts the vandal accounts were using automatically distorted random objects crossing the area of Israel, including objects such as coastlines that extend beyond these boundaries). Yet the impacts of the events did not end with the DWG reverting the vandal edits. These events had a direct connection with the introduction of a daily rate limit (set individually based on the seniority of the editing user and the number of edited entities, among other things [8]). The idea of such a limit had already existed for a while and was discussed within dedicated GitHub issues [6,7], yet it was only after members of the Israeli OSM community had commented within these issues and in a related community forum discussion [5] that the notion had been implemented. Interestingly, a DWG member which was handling the bans and reverts was the one who referenced the Israeli community to the forum discussion - in response to a question raised in the Israeli Telegram about whether any measures have been implemented to ensure this would not happen again, this user had suggested that they will ask that question in the relevant forum discussion. As extreme as this vandalism case was in comparison to other acts of vandalism or politically-motivated edits, its outcome tells a story regarding the fluidity of power dynamics within the project and accordingly - its vulnerability- and resilience-inducing mechanisms. The enforcement of rate limiting required a temporary coalition between individuals within the contributors and project components, where DWG members used the ‘traditional’ crossing path - from project to contributors, i.e. the DWG engaging with contributions to the point of joining the Telegram group - to mobilise support for their cause by encouraging contributors to engage with the management of the project, i.e. joining the GitHub discussion on rate limiting. This collaboration was in turn enabled by a joint sense of urgency stemming from the vandals violating the basic assumptions required for OSM to function - shared goals, adherence to community procedures, and mapping limited to verifiable objects. On the one hand, the temporary coalition formed between the local OSM community and the DWG members shows that the fuzzy nature of component boundaries allows for flexibility that enhances resilience in the sense of the ability to reorganise and adapt when conditions change. However, it shows that even temporary coalitions (it is useful to remember the Israeli community’s dissatisfaction with how the DWG handled the Jerusalem node issue [11]) of a handful of people reacting to a local event can lead to a global change occurring without a general consensus within the community (some dissatisfaction with the decision was already expressed [12,13]). If this becomes a common practice, it may undermine the stability of community procedures within OSM, especially if disagreements emerge due to clashing interests. Beyond this specific insight, this case allows mapping out different axes of power dynamics within OSM - the stakeholders (i.e. the system components), the crossing paths (e.g. project-to-contributors, contributors-to-infrastructure), the sources of capital (e.g. the masses, the project, access to resources and/or infrastructure), the nature of crossing (e.g. invitation, infiltration, takeover, acquisition), and motivations (e.g. individual/communal interests, safeguarding the project, values). Characterising other cases of external or semi-external engagement with OSM in light of these, e.g. corporate engagement with OSM, the collaboration of Meta and HOT (The Humanitarian OSM Team), and the development of Rapid, can produce insights on their deeper implications for the project and help imagine future paths of influence and their impacts.

Noting how the project reacted in face of this unique situation and the undermining of its basic assumptions facilitating the project helps uncover resilience- and vulnerability-inducing mechanisms within it, to characterize the range of possible external influences on the project, and assess their possible outcomes. OpenStreetMap (OSM) is generally considered to be a ‘do-ocracy’ [1], a governing system in which power stems from doing and those who do more (contribute more) have greater ability to influence the project. This does not mean that hierarchy within OSM is entirely bottom-up, as Fast & Rimmer’s systems perspective model of a Volunteered Geographic Information project suggests [2] - it is made of interconnected components (the technical infrastructure, project, and contributors) each providing a different level of direct access to the core of the project. Entities may move between these components, but a certain level of separation still exists, enforced informally or formally by gatekeeping procedures or individual acts. The fuzziness of borders and the interdependence of components open for multiple types of interactions that may translate to major impacts on the nature of the project. In this talk we use communication records from various media (the OSM_Israel Telegram group [3], community forum discussions [4,5], and GitHub issues [6,7]) to: i) to analyse a specific set of events - the politically-motivated edits in Israel and the subsequent introduction of rate limiting in OSM [8] - from a systems perspective; and ii) conceptually explore power dynamics and impacts within collaborative geodata projects and specifically OSM along with their implications for the project’s vulnerability and resilience. The chain of events started on 20 October 2023, when two members of the OSM_Israel Telegram group [3] reported receiving offensive comments on their recent edits. One of them noted that the commenting user was performing edits to the OSM data in Israel that were clearly acts of vandalism, i.e. deleting and distorting data. It was only the day after that the members of the Telegram group realised that these acts were part of a greater effort in which 3 newly registered OSM users were performing large-scale deletions and distortions of data in Israel. The timing of these edits, taking place while the Israel Defense Forces were launching airstrikes over Gaza strip in retaliation of the 7 October attack by Hamas, and their related changeset comments, e.g. “There is no country Israel & Free Palestine”, clearly attested that they were politically-motivated (For a representative example, see [9]). The events were quickly reported to the OSM Foundation’s (OSMF) Data Working Group (DWG), the voluntary body responsible for handling data issues such as copyright infringement and vandalism. The DWG issued bans to involved users, yet these were replaced in the next few days by more new users together making tens of thousands of similar edits. Meanwhile, one user, responding to these acts, further vandaled the map by ‘annexing’ part of the Gaza strip [10]. In the immediate aftermath of these events, most of the OSM data for Tel Aviv was deleted from the map and data all across Israel and the eastern Mediterranean basin, as far as Crete, Cyprus, and Turkey, suffered from distortions (the scripts the vandal accounts were using automatically distorted random objects crossing the area of Israel, including objects such as coastlines that extend beyond these boundaries). Yet the impacts of the events did not end with the DWG reverting the vandal edits. These events had a direct connection with the introduction of a daily rate limit (set individually based on the seniority of the editing user and the number of edited entities, among other things [8]). The idea of such a limit had already existed for a while and was discussed within dedicated GitHub issues [6,7], yet it was only after members of the Israeli OSM community had commented within these issues and in a related community forum discussion [5] that the notion had been implemented. Interestingly, a DWG member which was handling the bans and reverts was the one who referenced the Israeli community to the forum discussion - in response to a question raised in the Israeli Telegram about whether any measures have been implemented to ensure this would not happen again, this user had suggested that they will ask that question in the relevant forum discussion. As extreme as this vandalism case was in comparison to other acts of vandalism or politically-motivated edits, its outcome tells a story regarding the fluidity of power dynamics within the project and accordingly - its vulnerability- and resilience-inducing mechanisms. The enforcement of rate limiting required a temporary coalition between individuals within the contributors and project components, where DWG members used the ‘traditional’ crossing path - from project to contributors, i.e. the DWG engaging with contributions to the point of joining the Telegram group - to mobilise support for their cause by encouraging contributors to engage with the management of the project, i.e. joining the GitHub discussion on rate limiting. This collaboration was in turn enabled by a joint sense of urgency stemming from the vandals violating the basic assumptions required for OSM to function - shared goals, adherence to community procedures, and mapping limited to verifiable objects. On the one hand, the temporary coalition formed between the local OSM community and the DWG members shows that the fuzzy nature of component boundaries allows for flexibility that enhances resilience in the sense of the ability to reorganise and adapt when conditions change. However, it shows that even temporary coalitions (it is useful to remember the Israeli community’s dissatisfaction with how the DWG handled the Jerusalem node issue [11]) of a handful of people reacting to a local event can lead to a global change occurring without a general consensus within the community (some dissatisfaction with the decision was already expressed [12,13]).

By combining OSM data with CORINE Land Cover inventory, we study land use patterns around renewable energy infrastructures, facilitating environmental planning. We are witnessing the rise of a collective awareness of the importance of building a more environmentally sustainable future. Within this context, the relevance of renewable energy sources is widely acknowledged; however, to support the energy transition, the availability of reliable data about energy supply, infrastructures, and their environmental impacts is essential [1]. OpenStreetMap (OSM) emerges as a valuable data source to meet these requirements. In this work, we describe our research on evaluating the OSM database in a study of wind and solar energy infrastructures. As a case-study, we analyse two countries: Belgium and Ireland. Data within OSM is well-known to have a diverse level of completeness and granularity [2]. Considering OSM's vibrant mapping communities coupled with both (a) the environmental visibility of wind and solar energy infrastructures and (b) their relatively limited number compared to other built infrastructures, it is reasonable to assume that the majority of these installations are well mapped within OSM. OSM energy-related objects are mapped under the _“power”_ tag, with available key-value combinations to identify wind and solar sources. Wind turbines are commonly tagged as _“power=generator”_ and _“generator:source=wind”_, while solar farms are identified as _“power=plant”_ and _“plant:source=solar”_. By combining OSM data with the CORINE Land Cover (CLC) inventory we considers two research questions. Firstly, we seek to identify common mapping errors and tagging issues associated with wind and solar energy infrastructure representation within OSM. This involves examining geometries and tagging mistakes while evaluating the accuracy and completeness of these infrastructures. Secondly, we perform a geographical analysis to consider the distribution of infrastructures across various CLC land covers. We seek to detect patterns around land cover and renewable energy infrastructure. Our methodology is summarised as follows: OSM data, in PBF format, is downloaded from _GeoFabrik_. Initially here we just consider Ireland and Belgium due to local knowledge and their manageable data sizes. Analysis is performed using _Python_ and the _osmium_ library. Pending acceptance, source code will be made openly available on GitHub in documented Jupyter notebooks. We answer our research questions using three key steps: 1. Assess available wind and solar infrastructures in OSM for the correctness of OSM datatypes and potential geometric errors. 2. Differentiate between individual installations and larger "farms", to evaluate the quality and completeness of OSM data. 3. Investigate commonalities around land use surrounding renewable energy infrastructures using CLC. Initially, we extract all OSM objects with _“power”_ tag =_“plant”_ or _“generator”_, yielding a full listing of all available power sources. We filter solar and wind sources based on the _"generator:source"_ or _"plant:source"_ tags. The accuracy of the OSM datatypes and geometries is checked before moving to "farms" identification. To accurately differentiate single installations from farms, we analyze solar and wind sources separately due to their different geometric nature. We employ a point-in-polygon search with spatial indexes to assign nodes – of either wind or solar type – to intersecting areas of the same energy type. This process raises some geometric questions concerning the meaning of areas without nodes and nodes not linked to any area. We observed several issues: (a) not mapping individual panels within solar farms or defining turbines as circular areas, (b) nodes not associated with any area, (c) unlinked solar nodes representing private installations, (d) the absence of OSM areas or relations for turbines frequently indicated incomplete mapping. This final issue is significant: 91.4% of wind nodes in Belgium and around 87.4% in Ireland are not located within any mapped area. Considering the limited number of turbines included in OSM areas or relations, we employed spatial clustering on all turbines to identify wind farms and validate our findings by automatically comparing clusters with existing OSM areas and relations. DBSCAN (Density-based spatial clustering of applications with noise) is particularly suited for our purpose. One of the most important DBSCAN parameters is the maximum distance between two samples belonging to the same cluster which we set as 5 times the rotor diameter [3]. We assume a diameter value of 130 meters for all turbines [3] considering the frequent absence of the _"rotor:diameter"_ tag. Comparing clustering results with OSM data allows us to evaluate quality and completeness of areas and relations, to identify new farms, and to extend existing linkages to unassigned infrastructures. Due to their geometric nature, the process described cannot be applied to solar infrastructures. Given that all remaining solar data are areas, our methodology proposes two different processes, based on the power-tag value (“generator” or “plant”). Although OSM guidelines suggest that solar farms should be tagged as “plant”, deviations from this standard are possible. To avoid discarding valid data, we conducted an area-in-area search on solar generators. This approach assumes that if a solar generator area encompasses multiple solar generators, it may denote a farm. This process enables us to identify a few tagging mistakes where the _"generator"_ value was used instead of _"plant"_. While it may be possible to apply the same approach on solar _"plant"_, this would cause a significant data loss, thus we opt for keeping all plant-objects. Ultimately, this decision is strongly dependent on the data accuracy requirements. The refined datasets provide a comprehensive overview of wind and solar energy sources, facilitating further analyses into renewable energy. Our second research question considerations the analysis of land uses around energy infrastructure by integrating CLC. We use an arbitrary buffer of 1000m for this analysis. In Belgium, around 18% of wind farms are located within 1000 meters from heterogeneous agricultural areas, while 17% and 15% are near urban fabric and arable land respectively. In Ireland, most wind farms are near pastures (~24%), scrub (~18%) and forests (~18%). We notice how agricultural areas, in the form of heterogeneous agricultural areas, pastures, or arable land seem to prevail in both contexts. For wind energy, artificial surfaces appear relevant only in Belgium; however, both countries have solar farms near urban fabrics LC. Within the buffer from solar infrastructures this LC appears ~19% of the time in Belgium and ~12% in Ireland. In Belgium, heterogeneous agricultural areas (~19%) and forests (~12%) are also significant, while pastures predominate in Ireland (~31%), followed by arable land (~16%). However, 56% of the Irish territory is classified as pasture LC. Our work seeks to assess and improve completeness and accuracy of renewable energy infrastructure data in OSM. Our analysis distinguishes between individual installations and larger farms. Our strategy based on density-based clustering for identifying wind farms faciliates evaluation of the OSM data. We developed methods to associate solar panels to farms thereby mitigating tagging errors. Overall, we highlight challenges arising from inconsistent mapping practices and deviation from OSM mapping guidelines. The refined datasets offer comprehensive insights into wind and solar energy sources allowing additional analyses and assessment of their integration into the surrounding landscape. The next steps for this work include validating our approach for a larger set of countries and regions while also integrating further internal and external completeness and quality evaluations.

Our results show that corporate editing increased from 2016 to 2021, but has decreased since then. Nevertheless, in recent years there has been a diversification of corporations, with an increase in edits from Digital Egypt or Grab and other smaller corporations. Corporate mapping tends to focus more on high and medium HDI regions, but our results also suggest that there is only a small influence of corporate mapping dynamics on other parts of the OSM mapping community in a country. Introduction: In recent years, with the emergence of corporate editing in OpenStreetMap (OSM), there has been interest, and in some cases concern, about its influence in OSM. For instance, large corporations like such as Apple, Microsoft, Meta and Amazon have hired large teams to edit in OSM [1]. The launch of the Overture Maps Foundation, by Amazon, Meta, Microsoft and TomTom hosted by the Linux Foundation in 2022 and the release of its first dataset [2] has also led to heated debates on the OSM forum, regarding the future of OSM. Concerns have been raised about the monopolisation of geodata, the replacement of OSM by other sites or the backlining of OSM [3]. Consequently, analysing and continuously monitoring the impact of corporate contributors and continuing to observe their fluctuating patterns of editing will be significant to the understanding of the sustainability of OSM. Therefore, this talk will look at corporate editing in OSM at three scales - global, national and local to answer the two research questions: (RQ1) What is the impact of corporate mapping on global scale mapping? (RQ2) What is the impact of corporate mapping on country and small-scale mapping? Methodology: There are two main avenues to track corporate contributors: Either through corporate affiliated OSM User IDs (UIDs) or through corporate hashtags in OSM changesets. UIDs of corporation affiliated mappers have been used in the past to track corporate activity in OSM (e.g. [1, 4, 5]). A list of affiliated usernames can be collected from disclosed lists on the OSM Wiki or corporations GitHub pages [6]. The second way to track corporate edits is through corporate hashtags in changesets. Since 2009, it became possible to add hashtags to changesets in OSM, and this has become common practice, especially to show affiliation to regions, events, organisations or corporations [7]. For the analysis presented here, in total 24 companies were tracked including Apple, Kaart, Amazon, Microsoft, TomTom, Grab, DigitalEgypt, Mapbox and Meta. We used tracking with hashtags was used as proposed by [7]. The dataset used for the analysis integrated data from two sources: The OpenStreetMap History Database [8] and the OSM Changeset database. The OSHDB was used to derive OSM geometries and attribute information as well as information about the editors. The data was then intersected with a dataset of country boundaries to assign a mapping to a specific country. The OSM changeset dataset was joined to this contribution dataset. The dataset included a plethora of information, but the most relevant columns for the analysis were the OSM ID, Changeset timestamp, hashtags and User IDs, country, year and month as well as the geometry information – including the centroids. (We aim at presenting this dataset in detail in another workshop at SOTM 2024.) At the global level, two analyses were carried out. First, the temporal development of corporate and total edits from 2016-01-01 – 2023-12-31, including a breakdown by individual corporation. Second, the absolute number of corporate edits per country and the percentage of corporate edits based on total edits per country for the period 2019-06-01 to 2023-05-31 were analyzed. For an additional overview, the country-level results were grouped by Human Development Index (HDI) class, for a more in depth understanding of the spatial distribution of corporate edits in respect to socio-economic factors. Countries with more than 15% corporate edits and more than 100,000 total edits in this period were selected for an in-depth analysis. A total of 28 countries met these requirements and we extracted the monthly corporate and non-corporate edits. The overall timeframe for analysis was divided into two time periods: t0 (2019-06-01– 2021-05-31) and t1 (2021-06-01 – 2023-05-31). For each country we derived the change in average activity for both corporate and non-corporate mapping. Three countries were selected from the 28 countries with high corporate mapping activity for the small-scale analysis: Colombia, Indonesia and the United Arab Emirates. For these countries we produced a high-resolution spatial dataset based on a H3 grid utilizing the centroid geometry of each OSM contribution. We performed a spatial auto-correlation analysis to identify regions where corporate (and non-corporate) edits have increased / declined over the past years. In addition to the maps, a normalized confusion matrix was calculated to compare the spatial autocorrelation results and present the overlap or difference between the trends in corporate and non-corporate mapping. Results and Discussion: At the global scale (RQ1), corporate editing increased from 2016 to 2021 and has decreased since then. There is a wide variety of companies involved in OSM, but the large number of edits and its concurrent decrease in edits is mainly driven by three companies, namely Meta, Kaart and Apple. Other researchers have investigated corporate mapping activity [1, 4, 7], but a decline in their mapping activity has not yet been reported or expected. The observed decline is particularly evident in the case of Apple, which experienced a peak in edits during 2020 (14 million edits) and 2021 (12 million edits) before decreasing by more than half in 2022 (4 million edits). Corporate edits are concentrated in high and medium HDI regions, with almost 80% of edits distributed across 32 countries. As seen in other analyses, non-organised mapping tends to focus on very high HDI regions [9], while humanitarian mapping tends to focus on low HDI regions [10]. The results presented here suggest that corporate mapping tends to focus more on high and medium HDI regions. The discussion about digital inequalities and power imbalances that may arise from corporate contributions in particular countries or regions should be ongoing, as it is a discussion for OSM as a whole. As of now, it is not clear why the large tech corporates map less. At the same time, it is unlikely that all high and medium HDI countries are completely mapped in OSM already [10]. Regarding the small-scale analysis our results show that there is no strong correlation between the increase or decrease in the mean corporate or non-corporate edits for the three selected countries. For most regions with a strong increase (high-high cluster) or decrease (low-low cluster) in corporate or non-corporate edits, there is no significant change for the other. This suggests that there is only a rather small influence of corporate mapping dynamics on other parts of the OSM mapping community in a country. The ability to quantify the impact of corporate editing, particularly on volunteer mapping behaviour, continues to be an important measure for the OSM community. For example, further investigating would be necessary to understand the intentions and impacts of corporate mapping for various map features (not just looking at overall edit count). Understanding the intentions of different groups and communities in OSM and their impact on the data is a core necessity to obtain ’OSM Data Literacy’, especially for everyone who relies on high quality OSM data for research, business or decision making.

Our results show that corporate editing increased from 2016 to 2021, but has decreased since then. Nevertheless, in recent years there has been a diversification of corporations, with an increase in edits from Digital Egypt or Grab and other smaller corporations. Corporate mapping tends to focus more on high and medium HDI regions, but our results also suggest that there is only a small influence of corporate mapping dynamics on other parts of the OSM mapping community in a country. Introduction: In recent years, with the emergence of corporate editing in OpenStreetMap (OSM), there has been interest, and in some cases concern, about its influence in OSM. For instance, large corporations like such as Apple, Microsoft, Meta and Amazon have hired large teams to edit in OSM [1]. The launch of the Overture Maps Foundation, by Amazon, Meta, Microsoft and TomTom hosted by the Linux Foundation in 2022 and the release of its first dataset [2] has also led to heated debates on the OSM forum, regarding the future of OSM. Concerns have been raised about the monopolisation of geodata, the replacement of OSM by other sites or the backlining of OSM [3]. Consequently, analysing and continuously monitoring the impact of corporate contributors and continuing to observe their fluctuating patterns of editing will be significant to the understanding of the sustainability of OSM. Therefore, this talk will look at corporate editing in OSM at three scales - global, national and local to answer the two research questions: (RQ1) What is the impact of corporate mapping on global scale mapping? (RQ2) What is the impact of corporate mapping on country and small-scale mapping? Methodology: There are two main avenues to track corporate contributors: Either through corporate affiliated OSM User IDs (UIDs) or through corporate hashtags in OSM changesets. UIDs of corporation affiliated mappers have been used in the past to track corporate activity in OSM (e.g. [1, 4, 5]). A list of affiliated usernames can be collected from disclosed lists on the OSM Wiki or corporations GitHub pages [6]. The second way to track corporate edits is through corporate hashtags in changesets. Since 2009, it became possible to add hashtags to changesets in OSM, and this has become common practice, especially to show affiliation to regions, events, organisations or corporations [7]. For the analysis presented here, in total 24 companies were tracked including Apple, Kaart, Amazon, Microsoft, TomTom, Grab, DigitalEgypt, Mapbox and Meta. We used tracking with hashtags was used as proposed by [7]. The dataset used for the analysis integrated data from two sources: The OpenStreetMap History Database [8] and the OSM Changeset database. The OSHDB was used to derive OSM geometries and attribute information as well as information about the editors. The data was then intersected with a dataset of country boundaries to assign a mapping to a specific country. The OSM changeset dataset was joined to this contribution dataset. The dataset included a plethora of information, but the most relevant columns for the analysis were the OSM ID, Changeset timestamp, hashtags and User IDs, country, year and month as well as the geometry information – including the centroids. (We aim at presenting this dataset in detail in another workshop at SOTM 2024.) At the global level, two analyses were carried out. First, the temporal development of corporate and total edits from 2016-01-01 – 2023-12-31, including a breakdown by individual corporation. Second, the absolute number of corporate edits per country and the percentage of corporate edits based on total edits per country for the period 2019-06-01 to 2023-05-31 were analyzed. For an additional overview, the country-level results were grouped by Human Development Index (HDI) class, for a more in depth understanding of the spatial distribution of corporate edits in respect to socio-economic factors. Countries with more than 15% corporate edits and more than 100,000 total edits in this period were selected for an in-depth analysis. A total of 28 countries met these requirements and we extracted the monthly corporate and non-corporate edits. The overall timeframe for analysis was divided into two time periods: t0 (2019-06-01– 2021-05-31) and t1 (2021-06-01 – 2023-05-31). For each country we derived the change in average activity for both corporate and non-corporate mapping. Three countries were selected from the 28 countries with high corporate mapping activity for the small-scale analysis: Colombia, Indonesia and the United Arab Emirates. For these countries we produced a high-resolution spatial dataset based on a H3 grid utilizing the centroid geometry of each OSM contribution. We performed a spatial auto-correlation analysis to identify regions where corporate (and non-corporate) edits have increased / declined over the past years. In addition to the maps, a normalized confusion matrix was calculated to compare the spatial autocorrelation results and present the overlap or difference between the trends in corporate and non-corporate mapping. Results and Discussion: At the global scale (RQ1), corporate editing increased from 2016 to 2021 and has decreased since then. There is a wide variety of companies involved in OSM, but the large number of edits and its concurrent decrease in edits is mainly driven by three companies, namely Meta, Kaart and Apple. Other researchers have investigated corporate mapping activity [1, 4, 7], but a decline in their mapping activity has not yet been reported or expected. The observed decline is particularly evident in the case of Apple, which experienced a peak in edits during 2020 (14 million edits) and 2021 (12 million edits) before decreasing by more than half in 2022 (4 million edits). Corporate edits are concentrated in high and medium HDI regions, with almost 80% of edits distributed across 32 countries. As seen in other analyses, non-organised mapping tends to focus on very high HDI regions [9], while humanitarian mapping tends to focus on low HDI regions [10]. The results presented here suggest that corporate mapping tends to focus more on high and medium HDI regions. The discussion about digital inequalities and power imbalances that may arise from corporate contributions in particular countries or regions should be ongoing, as it is a discussion for OSM as a whole. As of now, it is not clear why the large tech corporates map less. At the same time, it is unlikely that all high and medium HDI countries are completely mapped in OSM already [10]. Regarding the small-scale analysis our results show that there is no strong correlation between the increase or decrease in the mean corporate or non-corporate edits for the three selected countries. For most regions with a strong increase (high-high cluster) or decrease (low-low cluster) in corporate or non-corporate edits, there is no significant change for the other. This suggests that there is only a rather small influence of corporate mapping dynamics on other parts of the OSM mapping community in a country.

The paper includes an introduction to crisis mapping and concludes with an analysis of students’ knowledge and skill gains, and attitudes towards map making. Students’ survey responses were analyzed using mixed methods. In conclusion, the paper proposes that the Mini-Mapathon course could be implemented in other schools with a larger sample size to investigate learning outcomes. . I designed and developed the Mini-Mapathon curriculum to answer three key research questions below. 1. How did the design support changes in students’ perceptions of their crisis mapping knowledge and skills? 2. How did participating in the Mini-Mapathon support student expressed interest in crisis mapping in the future? 3. How did the Mini-Mapathon support students in engaging crisis mapping? I designed and delivered the Mini-Mapathon, via three 45-minute Human Geography courses to 28 junior Asian high school students at an international school in Beijing, China. The English Language Learners (ELL) student population were all Chinese and their ages ranged from 16-18, consisting of 15 male students and 13 female students. Prior to implementing the research project with 28 Human Geography students, I researched the best way to teach crisis mapping to ELL students by participating in Mapathons and Mapalongs. I piloted three crisis mapping Mini-Mapathons for 55 Asian 4th grade students in three classrooms after learning crisis mapping was done effectively with 10 year old students in Milan, Italy (Gaspari, et al., 2021). The pilot programs with 4th grade Asian students and subsequent project were implemented only after the 4th grade students learned about crises in their IB-PYP curriculum, and after I conducted an extensive literature review of this relatively new (2005), interdisciplinary and innovative field of crisis mapping, investigated many mapping software platforms, and spoke to representatives from www.ushahidi.org, www.hotosm.org , and www.missingmaps.com. A website was built (www.crisismapping.weebly.com) to turn the Mini-Mapathon experience into an exportable educational activity that could be replicated or delivered in formal and informal learning environments. Using the ADDIE approach, I sought to design, implement, and evaluate a Mini-Mapathon curriculum to answer my three research questions. I implemented my applied research project on teaching crisis mapping through a Mini-Mapathon and collected pre and post surveys in late April, 2022, during the spring semester at an international high school in my three Human Geography classes. Twenty-eight Asian students participated in the Mini-Mapathon so that medicine and services could be delivered to vulnerable populations in Nigeria and Zimbabwe by Doctors Without Borders and The Red Cross. During the 45 minute Mini-Mapathons, students were taught how to map buildings and roads using Humanitarian Open Street Mapping software via www.hotosm.org and they took pre and post surveys so that I could better understand and measure how students learn during Mapathons and determine if my methodology for teaching crisis mapping was effective (Branch, 2009). The learning objectives of the Mini-Mapathon design were as follows: 1) Students will be able to co-create interactive open street maps using geo-spatial software. 2) Students will be able to analyze the role maps play in crisis response such as refugee crises and disasters and identify the stakeholders including citizens, international humanitarian organizations such as UNHCR, Doctors Without Borders, and Red Cross, NGO’s, government agencies, and military branches. 3) Students will be able to develop geographical knowledge and spatial awareness. I delivered pre and post surveys to better understand how students learn, what they learn, and assess the quality of crisis mapping instruction in my three Human Geography courses with 28 Asian high school students. How to Create an Account tutorial along with the other static and video tutorials can now be found on the website I built www.crisismapping.weebly.com. I began each class with a 2–3-minute video focusing on the problem, population in need and showcasing the work of the Spanish Red Cross, UNHCR, or Doctors Without Borders, to increase cultural and historical context and show the organization who can operationalize our map to provide relief to those in need. I then proceeded to explain that some places do not have accurate maps because they do not have Google cars driving around or adequate resources in the government to make up to date maps, however, volunteers like us can make the new maps together using satellite imagery. I asked the students to create their own OSM accounts in previous classes because we had been using the OpenStreetMap resource to explore chokepoints, or straights and canals, to better understand geography and global trade in previous lessons. I provided anonymous usernames and passwords if students had not yet created their OSM accounts to save time. Some opted to use the Tutorial How to Create An OSM Account and some students taught others how to create an account quickly. Next, I proceeded to implement the following step by step in class instructions in order to make learning visible and meet the academic language needs of the ELL students (Hattie, 2008; Yoder, et al., 2016). Step 1) Watch a fellow student map in front of the classroom following the teacher instruction through a four-step tutorial How To Map A Building. The tutorial can be found on www.crisismapping.weebly.com Step 2) Review the four-step process by coaching the student verbally through the four-step tutorial How to Map a Building. Step 3) Correct the teacher’s mistakes of not following the order and incorrectly mapping the building size, and mapping a shadow. Step 4) Answer any questions students may have. Step 5) Ask students to start mapping their first building and raise their hands before saving and uploading their work so the teacher or aid can inspect and correct their work if needed. PDF and video tutorials on How to Map a Building and How to Map a Road were delivered through the school’s information communication technology platform so students could learn at their own pace through multi-modal scaffolded instruction. The population sample of 28 Asian ELL high school junior students completed pre-surveys prior to the learning intervention or Mapathon and then completed the post survey. The pre and post survey questions were a mix of qualitative and quantitative questions (see Table 3). The quantitative survey data was analyzed using Microsoft Excel. The descriptive analysis was performed with SPSS to find the frequencies, percentages, the mean and standard deviation of survey question data. The descriptive statistics are presented below in the form of tables, graphs, and charts below. I used descriptive statistics and analysis instead of inferential statistics because this was a pilot project with a small sample size. The goal was to understand the impact of the new curriculum on this particular population and not to generalize effects of an intervention for all similar students.

In recent years, OpenStreetMap (OSM) has evolved from being a Volunteered Geographic Information Project to one of the most successful Geospatial Crowdsourcing Platforms in the world. Volunteers, governments, and corporations all make contributions to its global map. Corporate editors (CEs) are the latest entrant in the OSM ecosystem, and their prolific contributions have drawn significant interest from the OSM community as well as the scientific community. In 2018, the OpenStreetMap Foundation introduced a set of Organized Editing Guidelines in response to community outcry related to the edits made by these CEs and a perceived lack of dialogue and transparency between corporations and the larger community. Previous research has focused on the changing landscape of OSM users with the growth of corporate editing, cataloguing the global footprint of corporate editing and the map features that CEs are editing. Others have studied the impacts of having a dedicated workforce that can make significant changes to the map in a very short period of time, as CEs were shown to have different editing habits than volunteer mappers. This study focuses on the CEs themselves, as while other research has explored the impacts of their existence, they have not explored who these editors are, and the reason for their employment. We sought to learn more about the demographic makeup, careers, and motivations and community relationships of these individuals. With these three research objectives, we created an anonymous mixed methods survey that was distributed directly to every listed CE account provided in accordance with the Organized Editing Guidelines on the OSMwiki. Non-exclusive groups were created prior to the collection of results based on previous literature and our research objectives. These groups were then compared to each other using ANOVA and compared to the population using T-tests in R . A non-exclusive typology was also created after results were collected to allow for further analysis of results. This typology was based on the statistical distribution of answers to key questions and it, paired with the groups created based on literature, allowed for a multi-pronged analysis. The findings reveal that corporate editing in OSM is a legitimate career path and can be more nuanced than simply adding or editing features on the map. Though the most popular employment length was one year, some participants had been employed for upwards of five years. There is a group of CEs that spend almost no time directly editing the map in OSM, yet – on average – have been employed for longer than those who spend the most time editing. Given that over a third of participants mapped in OSM prior to their employment as a CE, it was not surprising that there are ties between CEs and the OSM community, but we found that there was a link between community involvement and job satisfaction, as there was significant overlap between the most satisfied and most involved respondents. When editing, all respondents edited a variety of features, no specialization where a CE would only work with a single feature type was seen. Some editors edited the map before making it a career, some started editing on their free time after getting a job as a corporate editor, and others do not map outside of work. There is also a variety of salary types with an hourly wage being the most popular, but other CEs being paid a monthly or annual salary. A profile of a typical CE was created using the mode of each question’s response and reveals many are enjoying their jobs and would like to continue. There is insight into the workplace by depicting the resources available to editors and a general framework of their work week, with 8-hour days, one project meeting per week, and good relationships between colleagues. There is not much direct interaction between the typical CE and members of the community, but they do use community resources (like OSMwiki) and consider its status as an open project important to their employ in the field. Unfortunately, we encountered several challenges in reaching out to individual editors as the organizations they work for explicitly prevented them from answering the survey. This had a significant impact on our ability to collect responses, as over half the CE community was made unavailable to this study. Due to low participation numbers, we must establish that our results do not serve as a definite representation of CEs. Low participation was also the rationale for the multi-pronged analysis, as we sought to learn as much as possible from a limited population. Though all CEs reserve the right to not participate in this study, the blanket refusal seen by some corporations is at odds with the autonomous agency which has been a tradition of OSM. At one company, all direct messages sent to any of their CE accounts on OSM redirect to the inbox of their manager, which raises similar questions. While our results may not provide a faithful representation of CEs, our work furthers conversation regarding these workers and broaches the topic of their agency.

With these three research objectives, we created an anonymous mixed methods survey that was distributed directly to every listed CE account provided in accordance with the Organized Editing Guidelines on the OSMwiki. Non-exclusive groups were created prior to the collection of results based on previous literature and our research objectives. These groups were then compared to each other using ANOVA and compared to the population using T-tests in R . A non-exclusive typology was also created after results were collected to allow for further analysis of results. This typology was based on the statistical distribution of answers to key questions and it, paired with the groups created based on literature, allowed for a multi-pronged analysis. The findings reveal that corporate editing in OSM is a legitimate career path and can be more nuanced than simply adding or editing features on the map. Though the most popular employment length was one year, some participants had been employed for upwards of five years. There is a group of CEs that spend almost no time directly editing the map in OSM, yet – on average – have been employed for longer than those who spend the most time editing. Given that over a third of participants mapped in OSM prior to their employment as a CE, it was not surprising that there are ties between CEs and the OSM community, but we found that there was a link between community involvement and job satisfaction, as there was significant overlap between the most satisfied and most involved respondents. When editing, all respondents edited a variety of features, no specialization where a CE would only work with a single feature type was seen. Some editors edited the map before making it a career, some started editing on their free time after getting a job as a corporate editor, and others do not map outside of work. There is also a variety of salary types with an hourly wage being the most popular, but other CEs being paid a monthly or annual salary. A profile of a typical CE was created using the mode of each question’s response and reveals many are enjoying their jobs and would like to continue. There is insight into the workplace by depicting the resources available to editors and a general framework of their work week, with 8-hour days, one project meeting per week, and good relationships between colleagues. There is not much direct interaction between the typical CE and members of the community, but they do use community resources (like OSMwiki) and consider its status as an open project important to their employ in the field. Unfortunately, we encountered several challenges in reaching out to individual editors as the organizations they work for explicitly prevented them from answering the survey. This had a significant impact on our ability to collect responses, as over half the CE community was made unavailable to this study. Due to low participation numbers, we must establish that our results do not serve as a definite representation of CEs. Low participation was also the rationale for the multi-pronged analysis, as we sought to learn as much as possible from a limited population. Though all CEs reserve the right to not participate in this study, the blanket refusal seen by some corporations is at odds with the autonomous agency which has been a tradition of OSM. At one company, all direct messages sent to any of their CE accounts on OSM redirect to the inbox of their manager, which raises similar questions. While our results may not provide a faithful representation of CEs, our work furthers conversation regarding these workers and broaches the topic of their agency.

A comprehensive evaluation of gasoline station infrastructure is necessary to ensure public safety and reduce fire dangers. This research, which focuses on Harare, Zimbabwe, uses Geographic Information Systems (GIS) to examine building patterns and access building footprints, road networks, and public facilities using the OpenStreetMap Database. Fuel station mapping and dataset overlaying allow to define fire risk levels that are susceptible to fire hazards and identify danger zones. This study supports risk management, public safety, disaster preparedness, and mitigation initiatives in Harare, Zimbabwe. Natural or man-made disasters pose serious risks to communities all over the world and frequently have dire repercussions, including the loss of life, destruction of property, and disruption of social order [1]. Fire occurrences are particularly dangerous among these calamities, especially when they include infrastructure such as gasoline stations [2]. The potential for large-scale fire catastrophes underscores the need of ensuring the safety of gasoline station infrastructure, as evidenced by occurrences documented in Zimbabwe [3]. Petroleum derivatives, such as gasoline, diesel, kerosene, and LPG, have the potential to ignite fires when handled improperly [4]. It is clear that a comprehensive fire danger assessment is necessary, which highlights the need for proactive fire management planning [4]. Between 1993 and 2004, there were around 243 fire-related incidents at fuel service stations worldwide that were recorded. it's evident that these sites present significant risks Geospatial technology has become an invaluable instrument for disaster preparedness, response, and mitigation as a result of these issues [5]. By offering open data necessary for disaster response and mitigation, initiatives such as Humanitarian OpenStreetMap and the utilization of platforms similar to OpenStreetMap have made substantial progress in these efforts [6]. These systems ensure the availability of high-quality data for efficient mitigation measures and provide quick and open access to geospatial data, facilitating prompt disaster response activities [7]. The OpenStreetMap data consists of many datasets that use points, lines, polygons, and area attributes to represent real-world features. These databases include characteristics that are useful for study, mitigation, recovery, and preparedness for disasters. Through the use of Geographic Information Systems (GIS) techniques, mapping into and querying the OpenStreetMap Database, this project seeks to overcome the difficulties presented by fire dangers, namely in gasoline station infrastructure. In order to identify danger zones and potential vulnerabilities, the research specifically aims to perform a thorough examination of building footprints, conventional construction standards, and public spaces such as marketplaces, parks, schools, hospitals, houses of worship, and road networks in Harare, Zimbabwe. Additionally, it seeks to map gas stations, obtain exact locations, and extract pertinent data from OpenStreetMap and other sources by utilizing Geographic Information System (GIS) approaches. The study also aims to categorize areas at risk of fire danger according to a number of factors, such as proximity to fuel stations and the position of LPG filling stations according to Zimbabwean government rules and retail premises, as well as other factors identified through spatial analysis. Additionally, it seeks to offer practical suggestions and solutions for improving public safety and lessening the effects of fire disasters in Harare, Zimbabwe, offering insightful information for initiatives related to disaster preparation, mitigation, and recovery. to advance resilience and sustainable development in the area while also adding to the scientific understanding of the dangers of fire hazards related to gasoline stations. This study's methodology combines spatial analytic methodologies, data extraction from OpenStreetMap and other sources, and Geographic Information System (GIS) analysis. To fully comprehend the gaps that now exist, we will first start by gaining access to the data that is already available on the OpenStreetMap Database. The gasoline stations will then be mapped into the OpenStreetMap database, where pertinent data such as locations and infrastructure aspects will be recorded. This information will then be taken out of OpenStreetMap. The procedure involves extracting comprehensive information on the locations of buildings, roads, and public spaces including playgrounds, marketplaces, hospitals, and schools from the massive OpenStreetMap database. A thorough examination of the geographic distribution of filling stations, public buildings, and fire service stations will be done using a geographic information system. The objective of this research is to categorize areas at risk of fire hazards according to the Zimbabwean government's standards for the placement of retail and LPG filling stations. These rules include factors such as the distance from fuel stations and other infrastructural concerns. To fully comprehend the spatial distribution of fuel stations in relation to fire stations, residential buildings, and public amenities like schools, hospitals, places of worship, markets, parks, and more, techniques like Euclidean, nearest neighborhood analysis, and geoprocessing analysis will be used. In order to do the study, the number of buildings in each of the four fire danger risk zones—very high, high, medium, and low risk—will be grouped and examined. In order to determine the number of structures in each of these designated zones, a query to the OpenStreetMap dataset will be made. This will yield important information on the possible effects of fire hazard events on different regions within the research area. This study seeks to give crucial information for risk and disaster management (preparedness, mitigation, and recovery) by undertaking a thorough investigation of fire hazard threats linked with petrol stations in Harare, Zimbabwe. By employing Geographic Information System (GIS) techniques and utilizing geospatial data from OpenStreetMap, the project aims to improve public safety, lessen the effects of fire disasters, and advance scientific knowledge of fire hazard hazards. Additionally, this study's conclusions and suggestions aim to promote resilience and sustainable development in Harare and beyond.

However, the granularity and inconsistencies in OSM data pose challenges in modeling AT users' movements at the street level. This study proposes a novel methodology to generate axial networks for AT users using OSM data, simplifying the network while preserving topology. Applied to cities like Turin, Tel Aviv, and San Francisco, this approach effectively streamlined pedestrian and bicycle networks. The proposed methodology can enhance AT infrastructure, contributing to safer and more efficient urban mobility. Introduction OpenStreetMap (OSM) offers comprehensive street networks that span nearly every city worldwide. The networks contain essential details like road type and name, and individual streets are often represented through multiple concurrent segments. The segments include separate lanes for motor vehicles, dedicated bike paths, and pedestrian walkways. OSM's comprehensive dataset allows the creation of specialized networks customized for pedestrian and cyclist analysis, providing users with a powerful tool for understanding and improving active transportation (AT) infrastructure. These specialized networks play a pivotal role in monitoring and understanding walking and bicycling patterns, contributing to infrastructure enhancement aligned with cities' goals for fostering AT to combat traffic congestion, obesity, and air pollution (Nelson et al., 2021) Nevertheless, the granularity of these networks may pose challenges in modeling AT users' movements on a street level. For example, when assessing AT safety or suggesting a walkability index at the street level, the current data representativeness on OSM necessitates significant manipulation to do so. Furthermore, owing to OSM's open-editing model, the standards for mapping elements are not consistently defined, leading to contentions and variations in data quality (Haklay, 2010). Individuals often map elements based on personal needs and knowledge, introducing inconsistencies in the dataset. Consequently, in some locales, all designated lanes for various users are meticulously mapped, while in others, only a single lane representing the presence of a street is depicted. Additionally, there are instances where only lanes for motor vehicles are detailed, with scant attention paid to lanes catering to other road user groups. Previous research has endeavored to address this issue. For example, a study suggested a topology-preserving simplification of OSM network data for large-scale simulation in sumo (Meng et al., 2022). However, they primarily focus on less complex areas and prioritizing vehicular considerations when generating the new network over those of AT users. Aim In this study, we propose an innovative solution to generate an axial network specifically designed for monitoring and analyzing AT users, using exclusively OSM data. Our approach simplifies the network while preserving its topology. We apply this solution across diverse spatial contexts, from straightforward geographic regions to complex urban environments. Furthermore, we implement our methodology in several cities worldwide—Tel Aviv (Israel), Turin (Italy), and San Francisco (United State)—each characterized by unique urban structures and varying levels of economic development. Methodology The preliminary tasks use OSMnx (Boeing, 2017) to acquire OSM street network data, converting it into a graph while correcting topological errors. Then, the data is stored in a geodata table, including polyline geometry, names, and road types. Our algorithm filters out unsuitable roads, like motorways and trunk roads, and replaces roundabouts with their central points. The network is then ready for the multilane detection algorithm. Polylines identified in a multilane scenario are aggregated into a centerline and added to the Simplification OSM Data (SOD) network. Other polylines are added to the SOD network, retaining their original geometry. A multilane scenario is identified when polylines share the same street name, have similar angles, and are close together. Polylines are grouped by street name, and azimuth (0°-180°) narrows the angle range to ensure that parallel lines are considered parallel, regardless of orientation. The Density-Based Spatial Clustering of Applications with Noise (DBSCAN) clusters similarly angled polylines using a 10° radius and a minimum of two samples. Outliers with significantly different angles are excluded. The remaining clusters apply a right-shifted buffer to each polyline. If two or more polylines in the same class overlap by at least 10% in the shifted buffer, they're classified as multilane, and the entire class is replaced with one or more centerlines. The core idea behind creating a new centerline is to identify its start and end vertices and then add intermediate vertices to preserve the overall shape of multilane polylines. Overlapping buffers are merged into a single polygon, and the two polygon vertices that best define the original polylines are used to establish the new centerline's start and end. Intermediate vertices are then added at regular intervals to maintain the original polylines' orientation. The simplification process introduces significant changes to the locations of many polylines, resulting in issues of continuity, topology, accuracy, and inconsistency in the SOD network. Most problems can be resolved using existing methods, but connecting roundabouts requires extra effort. This process has three steps: transforming the roundabout representation to a point, connecting nearby dead-end polylines, and linking polylines in proximity. Following these steps ensures proper continuity and maintains the network's topology. Findings The case study centered on Turin, Italy, simplified its street network to 11,807 polylines from an initial 49,750. This effort reduced the complexity of 411 streets, converting 138 roundabouts to single points. Despite some challenges near intersections, the final version preserved topology. For validation, 43 streets in Turin were reviewed, revealing a 51% success rate, 28% with minor flaws, and 14% with partial success. Issues such as threshold errors, external mapping inaccuracies, and ambiguous street configurations affected the results. Similar challenges were faced in Tel Aviv, Israel, where 50% of 22 test streets matched perfectly with the reference network. Yet, 23% had minor issues, and 9% were entirely incorrect. In San Francisco, the comparison showed 80% accuracy with 20 streets evaluated. While most streets were correctly simplified, minor flaws were present in a few cases, mainly due to inconsistencies between the SOD and reference networks. Overall, the methodology successfully streamlined street networks, although it achieved varying rates of success across different cities. Discussion Our study offers a robust methodology for generating axial networks for AT users using OSM data, balancing data simplification with topology preservation. Its successful application across diverse cities such as Turin, Tel Aviv, and San Francisco demonstrate its versatility and effectiveness in varied urban environments. The approach simplifies the complex urban network data, streamlining pedestrian and bicycle analysis while retaining essential details. This enables urban planners and policymakers to better monitor and understand AT patterns, leading to infrastructure improvements that support safer, more efficient, and environmentally friendly urban mobility. Our research offers both scientific contributions and practical benefits. Scientifically, it has been applied to evaluate the built environment for pedestrian walkability using a spatial data clustering approach. Additionally, it has been utilized in research to evaluate safety and bike network connectivity, aiming to improve bicycle and pedestrian infrastructure in California cities. Practically, this work has been published on GitHub, making the code accessible to everyone for their specific needs and goals. References Boeing, G. (2017).

The proposal illustrates the research undertaken to assess the performance of fAIR underlining ML model training, from the training datasets selection process, the choice of the metrics used to measure accuracy, and finally the analysis of the results obtained testing for different metrics. The research falls within the broader spectrum of research on understanding the fine tuning process for geographic domain adaptation in image analysis validation, particularly for building footprints detection. **Introduction** Building footprints features are useful in a wide range of applications such as disaster assessment, urban planning, and environmental monitoring (You et al., 2018; Owusu et al., 2021; Yang, Matsushita, & Zhang, 2023), and their identification has been gaining increasing interest and attention from the ML research for Earth Observation (Hoeser, Bachofer, & Kuenzer, 2020). Particularly in the disaster response context, accurate and prompt availability of such information is crucial (Boccardo & Giulio Tonolo, 2015; Deng, 2022; Sun et al., 2022). fAIr, developed by the Humanitarian OpenStreetMap Team (HOT), a fully open AI-assisted mapping service to generate semi-automated building footprints features, addresses this need (fAIr website, 2022). fAIr stands for “Free and open source AI that is resilient for local contexts, and represents the Responsibility of HOT for local communities and humanitarian mapping", reflecting the objective of HOT to improve and assist mapping for humanitarian aid and disaster relief. Useful open-source data sets of AI-generated building footprints exist (e.g. Microsoft’s global buildings dataset, available through Rapid, and Google’s Open Buildings for Africa and the Global South at large), however, the Machine Learning (ML) models are not currently open-sourced. fAIr, on the other hand, addresses the lack AI models openness by being a fully open source project (HOT Tech Blog, 2022). While in OSM building footprints mapping is currently supported in most countries through Rapid, "users should take care to ensure adjustments and corrections are made as needed" (Rapid - OSM wiki, 2024); fAIr goes over this issue by reintroducing _the human in the loop_. In fact, at its current state, fAIr allows OSM mappers to create their own local training dataset, train/fine-tune a pre-trained Eff-UNet model, and then map into OSM with the assistance of their own local model. In its initial release, the performance of the model following training was not assessed, thus the objective of this research is to address this gap. This proposal describes the research developed in recent months to assess how the ML fine-tuning process performs, investigating the currently used accuracy metric, and comparing against different sets of evaluation metrics. The final aim of this research is to advise on the optimal metric for this building footprints segmentation task. The research falls within the broader spectrum of research on understanding the fine-tuning process for geographic domain adaptation in image analysis validation (Rainio, Teuho, & Klén, 2024; Maier-Hein et al., 2024). **Data and Methodology** fAIr is a software service that performs semantic segmentation to detect building footprints from openly available local satellite and UAV imagery at high resolution (cm) (OpenAerialMap website, 2017). In computer vision (CV), semantic segmentation is the task of segmenting an image into semantic meaningful classes, which is performed with convolutional neural networks (CNNs) architectures (Hoeser & Kuenzer, 2020). The deep learning CNN model used in fAIr is called RAMP (Replicable AI for MicroPlanning), and its architecture originates from an Eff-UNet model (RAMP model card, 2020; Baheti, Innani, Gajre, & Talbar, 2020). With the aim to analyse the current validation accuracy performance and compare against other metrics, an initial literature review on fine-tuning processes for geographic domain adaptation in image analysis validation was performed, which led to outlining a list of candidates for validation metrics (Reinke et al., 2024; Maier-Hein et al., 2024). In parallel, manual labelling on selected areas of interest (AoI) was carried out on a data set of sixteen urban regions, chosen as the most representative of different grades of urbanity, density, regional characteristics, roof cover types, etc. The pre-processing of the AoI images was performed for each urban region through fAIr-dev website (fAIr website, 2022), and produced 256x256 georeferenced tiles for both the original RGB images and labelled masks (see example in Figure 3). Then, the ML training was run on all sixteen training datasets using an Nvidia Tesla T4 GPU, for different batch sizes, epochs, and zoom levels. **Preliminary results** Figure 2 shows an example of outcomes of the ML training for four of the urban regions with five types of validation metric (categorical accuracy, precision, recall, IoU - intersection over union, and F1 Score) and categorical cross entropy as the loss function. The analysis of the research results is still a work in progress. The performance of IoU, the suggested metric for this type of image analysis problem (Reinke et al., 2024), will be assessed against the currently used metric, categorical accuracy, and other commonly used metrics. As a preliminary example of future analysis, Figure 3 shows how categorical accuracy scores compare with other validation metrics at their final value, i.e. the value at the epoch at which the checkpoints are saved, which currently is set at the maximum for the validation categorical accuracy (early stopping). The different characteristics of the urban regions are also going to be assessed against the performance of the current model. From empirical tests, it is expected that the model has lower accuracy in more dense areas. Fig 4 seems to confirms that, for a specific epoch count (here 20 is shown as an example) and batch size, the performance is higher in urban regions that are more sparse and that present a grid disposition, compared to more dense regions, for all metrics except for Recall. The same figure, but for roof types, suggests that the model performance is lower for cement roof types, as opposed to mixed cover, metal and shingles covers. In terms of urban "type", the results suggest that the current model performs better in the refugee camps regions, and worse peri-urban regions, with higher variability among the validation metrics for semirural and highly urban regions. Further analysis on the statistical significance of these preliminary patterns is under way, with the possibility to extend the research to other urban regions. **Conclusions** To avoid overfitting of the training dataset, early stopping is in place, thus it is important to choose the optimal metric with respect to how fAIr performs, and the research is going to point out the statistical significance of different choices for the model performance and for different urban characteristics. Further research will concentrate on using other factors to help drive the fine-tuning process, like loss regularisation, and will extend the analysis to the prediction performance.

Current work-in-progress proposed indicators to assess attribute accuracy, with a focus on speed limits and methods for estimating the logical consistency of road data. Due to the crowdsourced nature of OpenStreetMap (OSM) and the lack of quality control during the contribution, the data quality issue has become a research focus [1]. Understanding and addressing these data quality issues can facilitate unlocking OSM's full potential for diverse applications. OSM data quality assessment methods can be divided into two broad categories: extrinsic and intrinsic. Extrinsic quality assessment methods compare OSM data with a reference dataset (e.g., authoritative data sources). This is where most initial research on OSM data quality started from [2-4]. Yet, a reference dataset may not always be available. On this ground, researchers called for attention to the intrinsic indicators of OSM data quality [5] and proposed intrinsic data quality measures based on the data, data history, and metadata [5-9]. It is crucial to acknowledge that the quality of OSM data is not a one-size-fits-all metric. Rather, it heavily depends on the purpose of the application domain, known as "fitness-for-use" [5,10]. The diverse application potentials introduce dynamic data requirements. Navigation is one of the primary application domains in which OSM plays a pivotal role. Among them, vehicular traffic constitutes a significant portion of road usage and has a substantial impact on urban mobility and infrastructure planning. Additionally, the complexities involved in automotive navigation and traffic systems require a higher level of data accuracy and reliability, making it a compelling starting point for investigating intrinsic road data quality. In the context of car driving, the attribute accuracy and logical consistency of road data are particularly important [11]. Attribute accuracy refers to the correctness and logical coherence of attributes associated with road features, such as speed limits, road classifications, and turn restrictions [12]. Logical consistency ensures that the road network data follows the correct topological rules, such as proper connectivity of different road classes. The attribute accuracy and logical consistency of OSM road data are essential for traffic planning and supporting navigation applications. To address the challenges of the evaluation of OSM data quality for navigation, when a reference dataset is unavailable, this research narrows its focus on assessing the attribute accuracy and logical consistency of OSM road data. To assess the attribute accuracy, we first identified important attributes related to car driving, such as road name, road class, surface, speed limit, capacity, height limit, total weight limit, and vehicle type. Then our method assesses the attribute completeness by looking into the tags related to the aforementioned attributes, and whether the relevant information is available. The attribute completeness provides us with a first overview of the attribute data. In the next step, a set of rules based on country-specific traffic laws is defined, and the relevant attributes are checked against these rules. So far, we have looked into the traffic law in Germany and defined rules for speed limits according to the road classes. Our proposed method looks into the “maxspeed” tag of each road segment, and verifies their value against the rule defined for the corresponding “highway” value. When a mismatch occurs, these road segments are identified and considered as inaccurate. The inaccuracy of the speed limit is calculated as the number of road segments with an invalid “maxspeed” value divided by the total road segments with “maxspeed”. At the current stage of our work-in-progress, we verified our method in the Heidelberg region, where the inaccuracy rate is very low. Regarding logical consistency, a set of rules is defined based on country-specific conventions. We acknowledge that different regions in the world have different road construction and road mapping conventions. So far, we have based on our case study in Germany, and defined rules for the values of the “highway” tag. These rules include: the value of the “highway” tag should be consistent along a path; a link road should be connected to its corresponding highway; connection of different classes of roads should be logically consistent (a way with a high level of importance in the road network should not connect directly to a way with a much lower level of importance). Our work aims to assess OSM road data quality with a focus on car driving. Current work-in-progress proposed indicators to assess attribute accuracy, with a focus on speed limits and methods for estimating the logical consistency of road data. In the next step, we plan to build more rules for speed limits, considering the geometry of the road and their neighbouring zone to infer the speed limit. We will also leverage machine learning methods to set up rule sets for speed limits and road connections for different regions of the world. With the proposed assessment, OSM data users can verify road data quality in terms of attribute accuracy and logical consistency, before their intended use. With the evaluation method, we also aim to inform the potential improvement of OSM road data quality, especially for navigation.

How do you do that — install Mapillary and go cycling? Print a map and use a pen to draw over it? Install an editor app and go tapping buttons? Just try to remember everything and bring it home to map in JOSM? Let's see what tools we have and how to make the best map with no money and lots of enthusiasm. Ground surveying for OpenStreetMap has been my passion for 14 years. In this time I tried virtually everything: from drawing walking papers by hand or printing them, to making photos, audio notes, using mobile editors, even building a hardware thing to attach to a car wheel. Ultimately I want to help everybody to collect as much data for OSM as possible, with the best quality attainable. And in this talk, I will dig some of the surveying history, as well as demonstrate a few modern ways, including the new notes mode present in Every Door app. You would definitely want to go out and map after seeing this talk.

This ensures that now almost 120,000 users get free and equal access to basic mobility solutions every day. With the release of version 8, this conference talk will give you an exclusive behind-the-scenes look at almost a decade of OpenStreetMap-driven open-source software development and delivery. Our successes and challenges, and how we stayed true to our values, providing free and open-source software as a non-profit organization. With over ten years of history and over 120,000 users, openrouteservice has established itself as a cornerstone in the area of open-source and OSM-based routing engines. Driven by an increasing availability of road network data through the OpenStreetMap project, openrouteservice could steadily grow and evolve and find its unique spot as a good addition among other routing engines such as OSRM and Valhalla. The current portfolio of freely available services now ranges from standard routing, isochrones and vehicle optimization to custom routing algorithms designed especially for use cases such as relief operations in flooded or earthquake shaken areas. Openrouteservice was created as part of a research project at the University of Bonn around 2008 and was moved to the University of Heidelberg in the subsequent years. It has since been steadily developed, maintained, and supported. In 2017, we launched our public and complimentary API, offering fair quotas for a diverse range of our mobility tools, including routing, isochrones, matrix, vehicle optimization, geocoding, and numerous other features. This was so well received that openrouteservice partnered up with the German “Federal Agency for Cartography and Geodesy” in 2018 to provide routing services to the German Federal Government. In early 2019 the project was transferred to the Heidelberg Institute for Geoinformation Technology (HeiGIT), a non-profit and non-governmental research organization associated with the University of Heidelberg. The combination of non-profit, non-governmental, research, and free and open-source software allows us to make decisions based on social, ethical and environmental reasons without being influenced by commercial interests. The resulting stability and continued support already motivated over 600 other prominent non-profit organizations to install and use openrouteservice and build on top of our service APIs to run their missions. These missions encompass scenarios such as disaster relief efforts, supply chain management, last-mile logistics for health items, accessibility analysis to ensure equal access to health facilities, or planning the support areas for fire brigades. With our latest release, version 8, we would like to take this opportunity to provide the OSM community, which we so heavily build on, with an insight into nearly a decade of OSM-driven open-source software development and delivery. What it takes to run and provide a global public API, and how we are navigating the current professionalisation push for open-source software to shift from formerly hacky self-hosted solutions to data centre ready deployments. We will also share details on how we deal and operate with the ever lasting questions about osm data quality, accuracy and explainability of our routing results.

The mapping carried out by the SAGEMA chapter of YouthMappers allowed sharing valuable information about Colombian flora with the university community, facilitating its conservation and recognition through the integration of collection data into OSM. The project aims to promote the conservation of threatened tropical ecosystems through open mapping. It involved the participation of 12 students and a training strategy through open workshops to replicate the project in other Latin American regions. The Universidad Nacional de Colombia is one of the most important ecological nuclei and connection points in Medellín and the Aburrá Valley. In its approximately 37 hectares, the university harbors a high diversity of fauna, especially birds, insects, small mammals, and reptiles, which find shelter, food, nesting areas, and a passage point in their biological corridor in the tree cover. Therefore, the conservation of this space is of special importance to the city. The collection stands out for housing various species representative of different Colombian tropical ecosystems, such as the dry forests of the Cauca and Magdalena canyons, the humid forests of Chocó, and the flooded forests of the Amazon, among others, offering students and visitors the opportunity to immerse themselves in the biodiversity of the extraordinary Colombian tropical forests and ensuring the maintenance of native species. The "Open Data, Vibrant Ecosystems" project aims to bring the university community closer to the care and appreciation of the flora and fauna present on the Universidad Nacional de Colombia, Medellín campus, through the recognition and appropriation of the living collection Arboretum and Palmetum Leon Morales Soto. It is based on open and collaborative mapping to encourage students to interact with the different species of palms, trees, shrubs, and herbaceous plants that the collection houses, and aims to go beyond visualization and consultation by inviting them to be active participants in the collection's tree inventory data collection, creation, use, and download through open data and the OpenStreetMap platform. As a result of the first phase of mapping the project, the collection's inventory was imported into OpenStreetMap, adding around 3000 new data points to the map. The project is developed in 3 phases: Training, Data validation in office and field, Data import to OSM. For the first phase, a work route was established for data import. First, information gaps and technical knowledge needed for the import were identified. Based on this analysis, collaboration was sought with volunteers from the OSM Colombia and OSM Latin America communities who had experience in tree mapping in OSM. A schedule of five training sessions was established for project members to acquire the knowledge and technical skills necessary for mapping the collection. As part of the project's dissemination and replicability strategy, it was decided to open the talks to the general public and especially invite the OSM Colombia and YouthMappers Latin America community to the training cycle. Five (5) training sessions were held in February and March 2024. The attendance range per talk was between 14 and 30 people, including students, educators, researchers, and institutions from 5 countries in Latin America (Colombia, Brazil, Mexico, Peru, Nicaragua, Chile). The training process covered topics such as data cleaning, mapping project documentation strategies, data import models with QGIS, urban trees and green areas in the OSM ecosystem, and open data licensing. To ensure the project's replicability, a YouTube channel was created with recordings of all the training sessions. A wiki was created documenting the data cleaning process, selected tags, the validation phase, and the import model. For fieldwork preparation, the QGIS program and the QField application were used. Through QGIS, tree data obtained from the university's Environmental Management System were imported, and then each campus of the Universidad Nacional de Colombia - Medellín Campus was divided into quadrants/polygons, with the aim that each member verified the tree data/points in the assigned quadrant. Field data verification was done through the QField application. The qfiel form identifies the mapper with their OSM username, allows them to add new individuals, map dead trees, and delete absent individuals. Information on species, growth habit, condition, and a photo was collected during the recognition. Python code was used to complement the information collected in the field, using the GBIF open repository API to add information about the botanical family for each of the mapped species. After socializing the import in the OSM Colombia community, the data import was carried out by quadrants under the user of each of the project participants, using an import model with QGIS that allows the translation of data into the tags used by the platform.

The mapping carried out by the SAGEMA chapter of YouthMappers allowed sharing valuable information about Colombian flora with the university community, facilitating its conservation and recognition through the integration of collection data into OSM. The project aims to promote the conservation of threatened tropical ecosystems through open mapping. It involved the participation of 12 students and a training strategy through open workshops to replicate the project in other Latin American regions. The Universidad Nacional de Colombia is one of the most important ecological nuclei and connection points in Medellín and the Aburrá Valley. In its approximately 37 hectares, the university harbors a high diversity of fauna, especially birds, insects, small mammals, and reptiles, which find shelter, food, nesting areas, and a passage point in their biological corridor in the tree cover. Therefore, the conservation of this space is of special importance to the city. The collection stands out for housing various species representative of different Colombian tropical ecosystems, such as the dry forests of the Cauca and Magdalena canyons, the humid forests of Chocó, and the flooded forests of the Amazon, among others, offering students and visitors the opportunity to immerse themselves in the biodiversity of the extraordinary Colombian tropical forests and ensuring the maintenance of native species. The "Open Data, Vibrant Ecosystems" project aims to bring the university community closer to the care and appreciation of the flora and fauna present on the Universidad Nacional de Colombia, Medellín campus, through the recognition and appropriation of the living collection Arboretum and Palmetum Leon Morales Soto. It is based on open and collaborative mapping to encourage students to interact with the different species of palms, trees, shrubs, and herbaceous plants that the collection houses, and aims to go beyond visualization and consultation by inviting them to be active participants in the collection's tree inventory data collection, creation, use, and download through open data and the OpenStreetMap platform. As a result of the first phase of mapping the project, the collection's inventory was imported into OpenStreetMap, adding around 3000 new data points to the map. The project is developed in 3 phases: Training, Data validation in office and field, Data import to OSM. For the first phase, a work route was established for data import. First, information gaps and technical knowledge needed for the import were identified. Based on this analysis, collaboration was sought with volunteers from the OSM Colombia and OSM Latin America communities who had experience in tree mapping in OSM. A schedule of five training sessions was established for project members to acquire the knowledge and technical skills necessary for mapping the collection. As part of the project's dissemination and replicability strategy, it was decided to open the talks to the general public and especially invite the OSM Colombia and YouthMappers Latin America community to the training cycle. Five (5) training sessions were held in February and March 2024. The attendance range per talk was between 14 and 30 people, including students, educators, researchers, and institutions from 5 countries in Latin America (Colombia, Brazil, Mexico, Peru, Nicaragua, Chile). The training process covered topics such as data cleaning, mapping project documentation strategies, data import models with QGIS, urban trees and green areas in the OSM ecosystem, and open data licensing. To ensure the project's replicability, a YouTube channel was created with recordings of all the training sessions. A wiki was created documenting the data cleaning process, selected tags, the validation phase, and the import model. For fieldwork preparation, the QGIS program and the QField application were used. Through QGIS, tree data obtained from the university's Environmental Management System were imported, and then each campus of the Universidad Nacional de Colombia - Medellín Campus was divided into quadrants/polygons, with the aim that each member verified the tree data/points in the assigned quadrant. Field data verification was done through the QField application.

The process includes tools for conflating data with OSM, supported by roles and tasks specific to this workflow. The AllThePlaces project supports this by extracting and mapping open (government) data to the OSM schema. A new tool, "DiffedPlaces", is proposed to automate diffs, perform data matching with an improved machine learning algorithm, and host the results. In addition, the existing OSM Conflator tool set, enhanced with a web-based data validation application, will be connected to DiffedPlaces. This is a work-in-progress report on an applied university research project to improve the workflow for integrating external "third party" datasets into OSM to complete OSM while adhering to the the import guidelines. First, the workflow for conflating (merging, fusing) external data into OSM is outlined with the main roles and tasks involved. Then some existing and missing software tools and challenges are presented. At the beginning there's data compliant to the ODbL license - especially selected open government data (OGD) - in raw format, or open data already mapped to the OSM schema from the existing AllThePlaces (ATP) project. ATP is a set of spiders and scrapers for extracting external open data. ATP implements periodic extraction, schema mapping, and hosting. A missing piece is the planned open source tool with the working title "DiffedPlaces", which will periodically process "diffs" from ATP and external data, i.e. OSM elements to be created, updated or deleted. DiffedPlaces will provide matching (incl. deduplication, record linkage, named entity resolution) and "diffing" external data to OSM as well as hosting. Another existing tool set is the OSM Conflator web application originally implemented by Ilya Zverev. It implements extraction and schema mapping (like ATP) as well as diffing, validating and hosting. Part of OSM Conflator is the cf_audit GUI web application, which presents the diffed data to be validated by the mappers. It already gives an idea of how diffing reduces tedious manual validation. Only after several validations and communication with the community, the data is finally updated to OSM. This tool will be extended to replace Overpass and it's limited matching capabilities with a connection to DiffedPlaces. This will allow OSM Conflator to focus on validation and hosting, while the matching and diffing would be done in one place, in DiffedPlaces, where other OSM tools and data editors can also connect. One of the challenges is data matching, which is being addressed with an extended random forest based algorithm from Piech et al. 2020. Another challenge is the management of the OSM elements to be deleted.

This presentation demonstrates how the Heatmap, in conjunction with our routing engine, can be utilized to identify and fill in missing ways in OpenStreetMap (OSM). We will discuss an algorithmic strategy for creating generated pathways and introduce a prototype of an interface that facilitates the easy integration of these pathways into OSM. We will showcase how Strava's Heatmap can promote OSM's goal of developing a more comprehensive global map, highlighting a mutually beneficial relationship between the two platforms. At Strava, we encourage and support over one hundred million athletes to be active. Athletes memorialize their physical activity via activity uploads that they can share with friends around the world. The vast majority of activities uploaded to Strava include time-series GPS traces. This wealth of information underpins our geospatial products, such as advanced routing capabilities and the visually engaging Global Heatmap. Through Strava Metro, we extend this aggregated and de-identified data at no cost to entities like governments, urban planners, and NGOs, aiding in the creation of more efficient human-powered transportation infrastructures. The backbone of Strava's routing algorithm lies in attributing popularity to roads and trails in our edge graph. We align raw GPS lines from Strava activities to these edges, enabling a popularity-driven routing experience that highlights preferred routes within the collection of OSM ways. With over a billion uploads, Strava athletes cover over 55% of the ways in OpenStreetMap with human-powered activity. In contrast, the Global Heatmap presents an unaligned aggregation of GPS lines for over one billion public activities, offering an intuitive visual representation to aid athletes in exploring their surroundings. It's this dataset that Strava Metro partners leverage to extract insights on the safety, directness, and overall appeal of routes in cities, parks, and recreation areas. We found that Metro partners will often overlay the Heatmap onto physical maps to identify and fill gaps in local pedestrian and cycling infrastructures. In response, we built a prototype of a tool that automates the identification and labeling of unaligned geometries, allowing our partners to streamline the process of integrating these new geometries into OSM. This innovative approach utilizes GPS data points unattributable to existing OSM edges to generate potential new pathways, enabling mappers to enrich the map with previously uncharted ways. Leveraging Strava's global scale, we have batch-processed a collection of these potential pathways worldwide. This data can help fill in unmapped areas and highlight regions needing more mapping attention. It can also highlight commonly used unauthorized paths and potential areas for infrastructure development. This presentation will delve into the algorithms that facilitate the generation of these new edges and explain how mappers can harness this data to enrich the OSM database, fostering a more comprehensive map for human-powered transport.

Speak it, of course! Like many programmers and heavy computer users, I suffer from chronic hand pain aggravated by computer keyboard use (often called repetitive strain injury, or RSI).

In this talk, I will live-demo how I edit code by voice, as well as tackling the following questions: 1. What is voice-coding like? What unique challenges does it present? 2.

This talk explores key findings on the transformative role of open mapping in this topic, demonstrated by three HOT collaborations; Anticipatory Response Program in Zimbabwe, Flood Tracking Project in Liberia, and Mapping for Anticipatory Action in Timor-Leste, plus analysis of post-disaster data demand from NGO and government responders. The talk will also surface insights on how OSM communities can increase their own disaster resilience and preparedness through mapping. Building on the foundations laid by the Missing Maps project, HOT is developing partnerships, data models and mapping campaigns that augment remote mapping efforts of humanitarian mappers (largely building / road network basemaps) through work with local communities, government and other actors creating data and analysis at a community level to conduct proactive disaster management. Anticipatory Response Program, Zimbabwe In Zimbabwe, a country impacted by disasters such as floods, cyclones, and droughts, the Anticipatory Response Program (ARP) explored anticipatory response through: - Identifying gaps in anticipatory planning, preparedness, and response that could be addressed with open geospatial data and tools. - Understanding the limitations in data tools and infrastructure supporting anticipatory action. - Stimulating opportunities for joint project collaboration between community organizations, disaster agencies, and the Open Mapping hub - East and Southern Africa. - Strengthening participation and ownership. - Developing data models through stakeholder identification of information relevant to the enhancement of disaster response Data collection involved mapping relevant features to inform better response capability by Caritas Zimbabwe and other stakeholders in Muzarabani district. This was conducted via remote and field mapping using open mapping tools and updating OpenStreetMap and Mapillary in 14 wards. Features included buildings, roads, and relevant points of interest (POIs) such as health facilities, shops, markets, schools, water sources, flood-prone road sections, religious centers, and public toilets. Data analyses evaluated suitability of POIs as evacuation centers and cash voucher assistance points and evaluated proximity to communities, thus visualizing community vulnerability to disasters and contributing to local contingency planning. Specifically, this information served as input to hazard maps and Multi-Hazard Contingency Plans (MHCP) for the pilot wards, ensuring authorities are prepared for disasters, and response efforts are supported by high-quality relevant geospatial data. Tracking Flooding in Rural Liberia Coastal settlements of Liberia - 565kms of mainly lowlands, hosting mangroves, swamps and nine river estuaries - face climate risks such as flooding, rising sea levels, and coastal erosion. Coastal cities experience annual average precipitation of >500mm, causing floods and sea erosion that disrupt livelihoods and damage properties and infrastructure. HOT’S Open Mapping Hub - West and Northern Africa, iLab Liberia and OSM Liberia collaborated to address urgent needs of the Commonwealth District in Grand Cape Mount County. An open, participatory mapping approach was used with key stakeholders to accomplish: - Mapping stakeholders and climate change-related interventions - Filling gaps in existing datasets, plus visualizations and decision-making tools for government and humanitarian actors. - Increasing climate resilience awareness through focus groups, radio programs, talk shows, town hall meetings, and resources for use by local authorities, youth, and women’s groups. - Mapping building footprints, road networks, waterways, and land use and collecting field data on buildings, education, health, commerce, infrastructure, waterways, and other amenities to provide detailed information on the vulnerability, exposure, and flood hazards for more robust data analysis. Data products were developed based on requirements and use cases from the National Disaster Management Agency, Liberia National Police, Ministry of Health, Environmental Protection Agency, Liberia Water and Sewer Corporation, Liberia Land Authority, Liberia National Red Cross Society, Ministry of Internal Affairs, Liberia Institute for Statistics and Geo-Information Services, Ministry of Public Works, Liberian Hydrological Services, Liberia Geographical Society, and others. Access to reliable data analysis hinders stakeholder’s disaster mitigation, preparedness, response, and recovery initiatives. These actors can now develop resilience programs to support the people in the district and adopt tools and workflows for other affected counties across Liberia. Mapping for anticipatory action in Timor-Leste Timor Leste faces natural disasters, including cyclones, earthquakes, tsunamis, and heavy rainfall. This is exacerbated by inadequate infrastructure and many communities who, despite developmental strides, grapple with poverty and food insecurity. Local map data plays a pivotal role in addressing these issues proactively, offering crucial support to local actors in decision-making and impact-based forecasting, but was incomplete and lacking depth. The Red Cross Crescent Climate Centre and Timor-Leste Red Cross worked with HOT’s Open Mapping Hub - Asia Pacific and OpenStreetMap Timor-Leste community on mapping, community engagement, and surfacing insights into areas at risk from floods, landslides, and other climate-related hazards. After identification of priority areas based on natural disaster risks, remote mapping and field mapping campaigns created basemaps augmented with relevant local features, including specific building features indicating susceptibility to floods or other hazards, such as minimum foundation height and building materials. Alongside open geospatial data, qualitative information on community perspectives on previous disasters / responses was collected using surveys, focus groups and SketchMap. The generation of geospatial data necessary for anticipatory action was complimented by key insights, eg. on flood impacts on livelihoods and a lack of essential early warning systems. However, there is high motivation, engagement, and interest in proactive local community action, incorporating open mapping, and opportunities for extending the initiative through government and community collaborations.

We'll be travelling 400km up to the International Space Station, to take a look at Earth through the lens of the Astro Pi computers that were sent there in 2020. This talk will focus on what has been learnt from years of giving young people the chance to take photos from the ISS using affordable commercial hardware. There will be plenty of the amazing images that have been captured so far, along with some examples of unexpected interruptions and the challenges when you can’t actually see or touch the equipment yourself. There will also be a chance for the audience to join in with an interactive game based on some of the photos. You'll need an Internet connected device to join in. Ground replicas of the actual hardware will also be on show and available for inspection.

(emf2024)</title> <link>https://media.ccc.de/v/emf2024-421-remote-controlled-chaos-cart-how-to-motorise-trash</link> <description>Using a fad of the 2010s and the UK's most popular river dweller the Leeds hackspace has combined 2 hoverboard wheels with a shopping trolley to create a monstrosity. Armed with a PA system, rally lights, under glow and 2 car horns it’s the perfect centre of chaos for protests or your ALDI shop. During our presentation, we invite the audience to delve into the fascinating world of motorising random objects and the art of upcycling, along with the myriad challenges we encountered along the way. From designing our own lithium-polymer batteries to countless iterations and rigorous testing, we'll discuss the intricacies of dealing with electromagnetic interference, experimenting with various motor controllers, and even designing our own from scratch. We want people to experience the shenanigans we went through and the fun we had along the way to hopefully get more people into whacky-wheeled…..wehicles. But it's not all talk! We're excited to demonstrate the trolley live, allowing you to experience first-hand the joy and sheer mayhem it brings. Our goal is to inspire you to embark on your own wacky-wheeled adventures, learning from our missteps and benefiting from our advice and tips. No Project is ever truly done lastly we want to look into the future: The intended use cases and how we aim to share our knowledge and plans with the wider community. Our commitment to openness and collaboration means that anyone bold enough to motorise anything around them can benefit from our experiences and insights.

So why not be Elliot Carver for a day and run your own Cable, satellite or UHF TV station - or even a whole network? With a few low-cost computer boards (Raspberry Pi's work but others are fine too) and video modulators, you can recreate the wonders of 1990s Cable TV in your own home, flat, or living room. I'll also talk about going further and how I recovered and resurrected a General Instrument ACC-4000 headend controller PC and used it to configure a small fleet of cable boxes.

However, this initial step is just the beginning of a complex journey toward achieving sustainability. One of the most significant challenges these companies face is addressing Scope 3 emissions, which are generated by their supply chains and lie outside their direct control. In this presentation, I will discuss the current state of sustainability efforts within the telecom industry, with a particular focus on the intricacies of reducing Scope 3 emissions. Rather than offering quick fixes, I will explore practical approaches companies can consider, such as switching to more sustainable suppliers, collaborating closely with existing suppliers, and gradually introducing contractual clauses that emphasize sustainability. Attendees will gain a realistic understanding of the challenges involved and will be introduced to strategies that can help their organizations begin the process of reducing their supply chain's carbon footprint. This discussion aims to provide a balanced view, emphasizing that while these steps are crucial, they require time, commitment, and a willingness to engage in long-term efforts.

Given that they’re lifelines of countries or even continents, they are important, yet we know little about them. So, what’s the rationale behind the large selection of submarine cables, often on the same route? Is it just about resiliency and shorter routes, or are there other differentiators? This talk will provide insight into the construction, operation, maintenance, and selection of submarine cables, using the connections between the United Kingdom and Continental Europe as an example. We will dive into what it takes to construct a submarine cable, discover why and how it breaks, and provide guidance on what to consider when purchasing.

Why, today, do the number of female directors hover around the 10% mark, even after #MeToo and #TimesUp? Female A-list stars still earn only about half as much as their male counterparts, partly because only about 12% of leading roles go to women.

RPKI/ROV is useful for origin validation but does not validate paths, ASPA is still an evolving technology, whilst BGPSEC has yet to be widely deployed and needs explicit router support along a path to achieve the full benefits. SCION has commercial and open-source implementations and is in production use by the financial services and healthcare industry in Switzerland and internationally. This includes the SCION Research & Education Network (SCIERA) which includes connections to OVGU Magdeburg. It is also currently being evaluated for use in government, power utility, aviation, military and other applications, with a number of vendors interested in implementing it in their products. This talk will discuss the SCION design and architecture, its trust model, how it can be deployed, as well as some deployment experiences to-date. It will also discuss the IETF/IRTF work, and the community efforts supported by the SCION Association to encourage further deployment and development.

Whether you favour 'are' or 'is', in many ways, data is plural. When we talk about data, we’re talking about different things, contexts, needs, and perspectives. Thinking of ‘data’ as a singular thing brings risks. We always have to set data in a more plural context and can never think about ‘just’ the data. And data we think of as being about us – singular, as individuals – is often about a plurality of others, and its value – to governments and tech companies – is in plurality or aggregate.

We weren’t quite sure whether it was safe to travel collectively, and the impacts of that difficult time continue to shape our railway network to this day. Meanwhile, many of us were exploring our own, hyperlocal neighbourhoods on foot with obsessive levels of depth that we never otherwise would have got around to. (Was I the only one who highlighted every street I walked in a London A-Z to see if I could get complete coverage?!) In 2021, I did a design-based MA all about railways, railway infrastructure, and what it means to travel and live communally. To do this, I walked all the way from London to Brighton (in sections), following the railway line as closely as possible. This is a talk about what I saw and what I thought about, and will hopefully be enjoyed by fans of trains, hiking, community and travel.

However, the increasing centralization of DNS traffic through large content-delivery hyper-giants (such as Google), coupled with the fact that the majority of DNS communication traditionally runs over unencrypted transports (UDP/TCP), has led to increased security and privacy concerns. In this talk, I will present recent results on the resiliency and efficiency of DNS, the state of adoption of protocols that enable DNS privacy and their performance implications.

In rural areas, we often lose cellular wireless signal entirely, even within highly technologically advanced economies such as the UK, EU, US etc. We then find that we are unable to send or receive text messages, even emergency messages. In the 1990s, visionary scientists and engineers developed alternative voice and messaging systems, using satellites as their ‘flying’ cell towers. We will discuss an example of such a pioneering network, called Iridium, which has operated successfully from the late 1990s right up to the present day. Today’s scientist and engineer visionaries are now proposing that the same ‘space-based’ capabilities could be added to our everyday smartphones, without needing to purchase a separate satellite-messaging device. This would allow our phone, when necessary, to switch from the land-based TN to the space-based ‘Non-Terrestrial Network’ (NTN). In this presentation we will discuss some of the technical challenges in achieving this ‘Direct-to-Device’ (D2D) satellite messaging feature, and some of the solutions which are being proposed, and even already being tested for real. One of the leading players in this space is Starlink, so buckle up for a wild ride!

Today, the railway system is now part public part private, leaving plenty of confusion for passengers. Who runs your local station? Who sets the rail fares, and who covers your refund? And where the hell does HS1 and HS2 fit into all this? I will take you through how the UK rail organisations are structured, who does and owns what, and how does this affect passengers? - What's the difference between Network Rail and National Rail? - How does split ticketing work? - What did Labour announce in April?

Today, the railway system is now part public part private, leaving plenty of confusion for passengers. Who runs your local station? Who sets the rail fares, and who covers your refund? And where the hell does HS1 and HS2 fit into all this? I will take you through how the UK rail organisations are structured, who does and owns what, and how does this affect passengers? - What's the difference between Network Rail and National Rail? - How does split ticketing work? - What did Labour announce in April? And most importantly: Who should I be angry at when I'm crammed in sideways on a delayed Sunday afternoon train to Leeds? No knowledge of the rail industry is required to enjoy this talk, but experts will find it depressing. I may swear, mostly about MPs.

If you've been to previous EMFs, you might recognise these as some of the themes for our puzzles! We are Dreamcat and we are a group of friends who made our first puzzlehunt for EMF 2018 and haven't stopped since. We love the combination of escape room, treasure hunt, video game, and just a dash of immersive theatre. We want to share that enthusiasm with you, talk about our top mistakes from the last 6 years and what we learned, and hopefully inspire you to go make your own puzzlehunts. Come along to learn: - How to co-opt serious IoT tools for frivolous escape room purposes - Why Portal is still the best video game ever made - How hard, actually, is “too hard” - Exactly how many paperclips were harmed in the making of this year's experience No spoilers for this year's puzzlehunt.

While building a new fiber network from scratch, Eurofiber faced a dilemma: We needed to install network devices in the great outdoors of Berlin’s heating power plant sites, but your typical data center devices wouldn’t fit in the standard telco cabinets available on the market. For our purposes, we require full-depth racks, access from both sides, and active cooling. So we could either go for smaller, hardened outdoor equipment, which limits the choice of devices. Or we’d have to buy concrete data center containers the size of a garage, which are larger than we need, take more bureaucracy to build, and are also expensive. To bridge this gap and keep the costs reasonable, we designed our own micro-datacenter, basically a larger street cabinet tailored specifically to our requirements: It provides active cooling, front and rear access, and fits full-depth devices while providing redundant power and sufficient protection from the elements. This adventure took us deep into the engineering world of the infrastructure required for operating network devices. Have you ever had to consider cooling capacities, battery temperatures, air-flow velocities, or noise emission laws? We take you through the design process as well as the lessons we learned on the construction site and the operational experiences after finally taking the network into production.

However, large-scale scans for server-side vulnerabilities remains a sensitive topic, due to their potential to harm servers, disrupt services, and incur financial losses. Even smaller, singular tests can be controversial, as demonstrated by incidents like the CSU scandal around Lilith Wittmann in 2021 or the Modern Solution case in 2023. The gray area surrounding the legality, ethics, and industry perspectives on server-side scanning has led to hesitancy among researchers and ethical hackers, creating a critical gap in our understanding of how to conduct such scans responsibly. In this talk, we investigate and interactively discuss the murky boundaries of vulnerability scanning by exploring five typical scanning scenarios that researchers face on the Web. Drawing from We give insights into 23 in-depth interviews we conducted with legal experts, research ethics committee members, and website/server operators to identify what types of scanning practices are acceptable and where the red lines are drawn. We further substantiate these insights with findings from an online survey conducted with 119 server operators. Attendees will gain great insights into the current state of Web scanning, including the lack of judicial clarity and the ethical dilemmas researchers and ethical hackers face. This interactive session also offers a platform for audience members to challenge their own understanding of ethics, share opinions, and contribute to shaping the future of responsible Web security scans. In this talk, the audience will: Get an in-depth understanding of the legal and ethical challenges associated with large-scale server-side scanning research. Learn current best practices for conducting responsible Web security scans (at scale).

This progression has brought with it novel classes of security flaws. In this talk we review how client-side variants of injection vulnerabilities such as cross-site scripting (XSS), cross-site request forgery (CSRF) and the recently discovered client-side request hijacking, arise and how traditional defense mechanisms are ineffective. We summarize recent research in this area which shows that such issues are widespread and can have a diverse range of consequences. We go on to show how dynamic taint-tracking has proved to be an effective technique for the discovery of vulnerabilities in client-side JavaScript. The initial overhead in implementing tainting is, however, extremely high, as it typically involves delving into the inner workings of modern web browsers and JavaScript interpreters. We show how Project Foxhound (https://github.com/SAP/project-foxhound/) can help to reduce this burden by providing a flexible, open-source tool which can be fully integrated into browser automation frameworks such as Playwright. Foxhound is gaining traction in the community as the go-to tool for client-side vulnerability studies. We finish the talk by showing how Foxhound can also be used in privacy studies, an update on upcoming features, and how the community use and contribute to the project to help build a safer web!

While GenAI offers tremendous potential, it also has a darker side, such as its use in creating deepfakes that can spread misinformation, manipulate political events, or facilitate fraud, as demonstrated in a live deepfake example. Malicious variants of GenAI, are used in phishing attacks, social engineering schemes, and the creation of malware. Additionally, GenAI enables more intelligent network attacks through autonomous botnets decreasing the risk of exposure. Despite these risks, GenAI also provides defensive advantages by enhancing security measures, such as improving threat detection, strengthening access control, and identifying code vulnerabilities. This is exemplified in a live demo showcasing deepfake and AI-based content detection. The presentation also examines the different types of attacks that AI models, including GenAI, are susceptible to, across any task, model, or modality. This includes adversarial attacks, where inputs are specifically crafted to deceive AI systems. Additionally, attacks such as Prompt Injection and Visual Prompt Injection manipulate inputs to mislead models. However, navigating the complex landscape of AI compliance is essential. Organizations must adhere to regulations like the EU AI Act and standards such as ISO 27090, while also following guidelines from bodies like OWASP to ensure the security, transparency, and ethical use of AI systems. The OWASP AI Exchange plays a key role in modeling threats to GenAI, addressing risks and point out solutions. To defend against these threats, various detection and mitigation techniques have been developed and will briefly be presented.

Today, OAuth protects sensitive financial APIs, powers identity verification systems, and secures modern app ecosystems — yet, many implementations remain vulnerable to attack.

However, these features can also introduce security and privacy issues for their users, mainly through a technique known as extension fingerprinting — where malicious websites track users based on the extensions they have installed. This is particularly interesting since many websites rely on advertising-based revenue for their existence, and the cookie-less form of tracking is also increasingly getting traction on the Web. Popular libraries such as FingerprintJS and Castle have already incorporated extensions as identifiable sources in their armor. In this talk, we will present the growing threat of browser extension fingerprinting, shedding light on how extensions can inadvertently expose both users and the extension to certain risks. Our recent research uncovers that over 3,000 Chrome and Firefox extensions are vulnerable to fingerprinting through techniques such as JavaScript namespace pollution and other observable side effects despite existing defense mechanisms [1]. The audience will takeaway the following: What are some of the ways by which browser extensions can be fingerprinted. The risks for both user privacy and extensions' behavior. Insights from recent research on vulnerable extensions. Potential strategies to mitigate fingerprinting risks. And, of course, how to keep your extensions from being the "most wanted" on the Web!

The EU Digital Identity Wallet (EUDI Wallet) represents the largest implementation of its kind to date and brings with it significant challenges, particularly in terms of security, privacy, and interoperability. To address these challenges, the EU has chosen to leverage open standards widely adopted in the web ecosystem — such as OpenID for Verifiable Presentations (OpenID4VP) based the widely-used web standard OAuth 2.0, and Selective Disclosure JWT (SD-JWT) built on the JSON Web Token (JWT) framework. However, wallet ecosystems operate quite differently from the traditional web, requiring adaptations to these protocols to meet the unique demands of secure, decentralized identity management. This talk will provide a comprehensive overview of the EUDI Wallet's architecture and the key challenges posed by adapting native web protocols for wallet ecosystems. It will also explore the crucial role browser vendors will play in ensuring the security and smooth functioning of this new digital identity landscape.

However, they are exploited by attackers who might request internal resources or non-public services. This attack is called Server-Side Request Forgery (SSRF).

This talk will explore the security of SAP systems from an attacker's perspective, uncovering common vulnerabilities and pitfalls and their respective impact. Drawing from extensive penetration testing experience, this presentation will provide a deep dive into how attackers might exploit SAP vulnerabilities and offer practical guidance on mitigating these threats. We will begin by highlighting prevalent SAP vulnerabilities discovered during real-world pentesting engagements, covering key attack techniques used against SAP systems that exploit misconfigurations, insecure coding practices, and authentication flaws. As an example, we will illustrate the configuration options of SNC, the proprietary protocol for transport layer encryption in SAP environments. Using the open-source tool sncscan, security professionals and administrators alike can assess the encryption and signing settings of SAP systems, ensuring the confidentiality and integrity of sensitive data. The session will also provide actionable guidance on mitigating these vulnerabilities, focusing on best practices and tools that can significantly enhance the security posture of SAP systems. By raising awareness of common vulnerabilities and pitfalls we aim to empower security professionals and SAP administrators to better protect their systems against potential exploitation.

Increasingly, organizations across diverse sectors are recognizing the value of open data and its potential impact on societal development. Several organizations have made a commitment to open up their data and actively contribute to OpenStreetMap (OSM). However, as OSM is an open-source community project, decisions and action are guided by community consensus. For any organization seeking to integrate its data into this platform, obtaining local community support is essential. The OSMer in Residence program serves as a crucial link between these organizations and the dynamic OSM community in Africa. Based on the concept of the Wikipedian in Residence, the OSMer in Residence program is designed to embed an OSM subject matter expert in a host organization or institution to maximize the value for the host organization in terms of their ability to leverage OpenStreetMap as a database that supports improved humanitarian and development outcomes in accordance with OSM community norms. In its pilot phase, Open Mapping - West and Northern Africa Hub(WNAH) collaboratedwith Médecins Sans Frontières/Doctors Without Borders (MSF), a humanitarian organization that provides emergency relief to some of the most vulnerable and excluded communities around the world, with data and maps being of high importance to supporting their operations. This pilot phase has led to workflow proposals facilitating the integration of an organization's data into OpenStreetMap by involving the local community where the data was collected.

However, these advancements have not uniformly benefited communities in developing countries. Nonetheless, OMDTZ tirelessly seeks solutions to ensure more high-quality data are gathered, with low cost and extensive local involvement. One standout initiative involves a customized tricycle, known as bajaj, which is cost-effective, enabling access to streets of varying conditions. Equipped with an affordable street view camera, it collects images used to automate generation of vector data attributes to enrich OpenStreetMap. This session aims to share the experience and process, inspiring other communities to consider similar adaptations. Over the years, OMDTZ and other volunteers have spearheaded a number of initiatives aimed at updating OpenStreetMap through various projects and mapathons in Tanzania. These efforts have added countless buildings, roads, and amenities, impacting social well-being and lifesaving initiatives. As technology has advanced, methods for data creation and updating have evolved, leveraging machine learning, AI, deep learning, and virtual reality to streamline processes. In line with these advancements, OMDTZ has invested in methods to ensure efficient and high-quality data capture. One such method involves using Mapillary to capture street view imagery, which is then utilized to automate the generation of vector data and attributes such as road surface, traffic signs, and drainage coverage. Additionally, OMDTZ has customized Bajaj, equipping it with navigation and a GoPro Max camera for data collection.

However, it is currently also facing of a number of challenges: For example, it needs to keep being able to cope with the growing amount and richness of OSM’s map data, as well as to afford the increasingly important task of keeping the map up to date. This talk outlines a proposal to transform iD’s current user interface centered around OSM’s data model into an adaptive user experience that is better tailored towards the needs of individual mappers and outlines an approach of how we can get there as a community. In the past, iD had to and has overcome several challenging hurdles to become what it is today: A quite unique map editor that is the point of entry of most contributors of OpenStreetMap into the world of mapping. Today, iD is facing of a number of signifiant challenges to make it even more usable to a wide user base, and will continue to do so into the foreseeable future especially in regards to make it fit for the mapping topics of the future. For example, the editor needs to be able to cope with the growing amount and richness of OSM’s map data as well as as the increasingly important task of keeping the map up to date. The design of iD’s current user interface is substantially based on OSM’s data model. This can be seen for example in the workflow of creating a new map feature: It starts out with a blank “dummy” map geometry which – in a second step – has to be converted into a map feature by choosing a preset. While this is true to the way OSM represents this information in the data (i.e. in the form of nodes, ways and relations which are enriched with tags), this is for most simple use cases an unnecessary complication. Instead of primarily catering to the needs and requirements arising from the underlying data structures, iD’s usability should be instead built around the needs of of the different groups of mappers. And as these vary quite significantly depending on the interests and/or experience of the individual mappers, a promising approach to bring all of these together is to evolve iD’s user interface into an adaptive mapping experience with the goal to make vital mapping workflows intuitive, easy, fast and delightful. This transformation will definitely not be a small endeavor and is far from finally defined: in fact this should only be a start of a larger discussion.

Streets have many lanes. Buildings have entrances, 3D shapes and POIs inside. And let's not even start talking about the complexity of a major railway station. This talk will take a systematic look at the different ways how complex objects are being mapped in OSM. We explore how editors cope with the complexities of detailed mapping and discuss the implication on how our processing tools need to change to better handle relationships between objects. In the early OSM days, when the map was still largely a white canvas, it was very easy to stick to a simple one-to-one relationship between real-world features and OSM objects. A street is a way. A building is a single closed way. But the more we get into the details of mapping, the more this one-to-one principle gets us into trouble. Streets have many lanes. Buildings have entrances, 3D shapes and POIs inside. And let's not even start talking about the complexity of a major railway station. For some of these complex constructs we have developed mapping schemas - using special tagging, relations or relying on spatial properties. But more often than not, the question of relationship between OSM object is sidestepped. The situation is more dire on the side of the processing tools. Most generic tools still look at every OSM object as an isolated feature. The tools that do process complex objects often do so only for a very specific type like 3D buildings or turning restrictions.

Unfortunately, many of the world’s cities still lack basic information on their own transport systems, leading to decisions measured against anecdotes rather than data. Using new tools for data processing and display, OpenStreetMap can provide the information that governments need to make better decisions. In this panel we will share recent success stories of cities adopting OSM-based metrics to plan better transport. We will reveal new tools that governments, mappers, and advocates can use. And we will discuss the challenges that still remain and the roles the OSM community can play in overcoming them. Transport is among the largest sources of greenhouse gas emissions, and transport emissions are growing especially quickly in the Global South. Experts agree that vehicle electrification will not be sufficient to avoid climate catastrophe: we also need to redesign cities to make it easy for people to walk, bicycle, or ride public transport instead of driving. OpenStreetMap can help. OpenStreetMap can empower cities to make planning decisions based on real data, and to set more meaningful goals for progress. OSM has empowered cities like Fortaleza and Recife, Brazil, to plan expansions of their bicycle lane networks that serve the greatest number of potential cyclists. OSM has helped cities as distant as Seattle, USA; Jakarta, Indonesia; and Pimpri-Chinchwad, India, to optimize their public transport networks and make it easier for everyone to ride the bus. And this is only the beginning. New tools are proliferating, such as ITDP’s Atlas of Sustainable City Transport and Trufi’s GTFS-Builder. These tools make it much easier to turn OSM data into useful indicators that can guide city policy. In the case of Trufi’s work, it does so by converting OSM data into industry-standard formats that can be used for trip planning or network analysis, As tagging evolves, OpenStreetMap is emerging as a solid foundation for creating multimodal route planning networks, thanks to its comprehensive information for generating integral maps. Furthermore, Trufi has developed a specific course on mapping public transportation routes, with the objective of training the OpenStreetMap community to contribute effectively to this particular aspect within the platform. ITDP’s Atlas, on the other hand, uses OSM as well as other open sources to present measurements of meaningful indicators that city governments can use to set goals or compare themselves to nearby jurisdictions. Some challenges, however, remain. It can be difficult to explain the virtues of OSM to governments who have never used it before. The tagging schema does not include certain nuances that are important for bicycle infrastructure planners (although a current proposal remedies many issues). And, looking more broadly into the future, there are many promising opportunities for the OSM community to push into new frontiers of data on topics like road usage, footpath quality, and parking. In order to prevent catastrophic climate change, we need to change the way people move around cities. In order to do that, we need maps.

It has diverse usability including the general public to governmental and non-governmental organizations. This abstract presents the usage of OSM in general and in the context of Nepal. OSM is used by the local community, the government sector and NGOs, tourism, classrooms, and various projects contributing to the development and gender equality making it a versatile data source. OSM gives a sense of empowerment and responsibility to individuals and contributes to fostering resilience and sustainable development. OpenStreetMap (OSM) is a free and open-source mapping platform where individuals collaboratively create, edit, use, and share geospatial data. OSM is used by a variety of users and stakeholders for their respective purposes. For the general public OSM is used for navigation because of its user-friendly nature. Mobile applications like MAPS.ME and OsmAnd provide offline access to maps. Additionally, it facilitates community engagement bringing a sense of empowerment and responsibility among individuals. Government sectors and NGOs use OSM data for planning developmental activities. The OSM data is extensively used in humanitarian response, Nepal is prone to disasters like earthquakes, landslides, and floods OSM has played a crucial role in allowing volunteers to respond quickly with the most updated maps with local information. OSM also plays an important role in tourism; guides, hikers, trekkers, and mountaineers use tourist maps prepared using OSM data as it provides detailed maps of hiking trails, mountain peaks, and natural landmarks. Gender equality is also an important domain that OSM has impacted upon, its various projects of mapping women-centric points of interest, addressing the issue of female genital mutilation, She Leads She Inspires programs, and empowering women as contributing to it remotely itself is the task that most females prefer to do. The students in the classrooms use OSM data for their projects and research. OSM data is preferred in the analysis as it is up-to-date and contains detailed information.

It has diverse usability including the general public to governmental and non-governmental organizations. This abstract presents the usage of OSM in general and in the context of Nepal. OSM is used by the local community, the government sector and NGOs, tourism, classrooms, and various projects contributing to the development and gender equality making it a versatile data source. OSM gives a sense of empowerment and responsibility to individuals and contributes to fostering resilience and sustainable development. OpenStreetMap (OSM) is a free and open-source mapping platform where individuals collaboratively create, edit, use, and share geospatial data. OSM is used by a variety of users and stakeholders for their respective purposes. For the general public OSM is used for navigation because of its user-friendly nature. Mobile applications like MAPS.ME and OsmAnd provide offline access to maps. Additionally, it facilitates community engagement bringing a sense of empowerment and responsibility among individuals. Government sectors and NGOs use OSM data for planning developmental activities. The OSM data is extensively used in humanitarian response, Nepal is prone to disasters like earthquakes, landslides, and floods OSM has played a crucial role in allowing volunteers to respond quickly with the most updated maps with local information. OSM also plays an important role in tourism; guides, hikers, trekkers, and mountaineers use tourist maps prepared using OSM data as it provides detailed maps of hiking trails, mountain peaks, and natural landmarks. Gender equality is also an important domain that OSM has impacted upon, its various projects of mapping women-centric points of interest, addressing the issue of female genital mutilation, She Leads She Inspires programs, and empowering women as contributing to it remotely itself is the task that most females prefer to do. The students in the classrooms use OSM data for their projects and research. OSM data is preferred in the analysis as it is up-to-date and contains detailed information. Different student clubs like the Geomatics Engineering Society (GES), a registered OSM community in Nepal conduct training, workshops, and mapathons contributing to capacity building. Overall, OpenStreetMap offers a spectrum of usability to individuals, volunteers, companies, and organizations and stakeholders ranging from navigation to disaster response and empowerment of individuals and community as a whole.

Initially, the project focused on developing a robust deep learning framework, which required extensive manual labeling of images to train the model effectively. Recognizing the impracticality and time-consuming nature of manual labeling, we conceptualized an approach to expedite the labeling process using cluster algorithms and graph information. Our method involved an automated labeling algorithm, which significantly accelerated the annotation phase. This algorithm demonstrated remarkable efficiency, automatically labeling images with high accuracy, thereby drastically reducing the manual effort involved. During the implementation, we discovered that our automated labeling algorithm was, in itself, the comprehensive solution for the classification task we aimed to address. This realization highlighted that our initial objective of deploying a deep learning model could be achieved through "classic" means. In conclusion, our project unveiled that the automated labeling algorithm was not just a tool to facilitate deep learning, but an effective standalone solution in itself.

We'll uncover the information hidden inside big image collections with Vision-Language Models (VLMs) showing us the way. Who knows which forgotten gems await us? In the first part, we'll use CLIP and FAISS to go on a treasure hunt in your photo collection. You'll learn how to filter through millions of images in a breeze, using natural language. Bye-bye endless scrolling, hour-long tagging, and frustrated folder searching. In the second part, we will harness the power of VLMs to help us caption images – translating pixels to words. Then we'll make use of the BERTopic library to reveal even deeper insights into your photo collections. By the end of this talk, you'll be equipped with the knowledge and tools to unlock new insights, identify patterns, and make your image data work harder for you.

In this talk, we will delve into the technical details of asyncio and show how it can be used to improve the performance of Python applications. We will start by discussing the difference between threading, multiprocessing and async programming. Then, we will introduce the basic building blocks of asyncio: Event loops and Coroutines. We will dive deep into the way Coroutines work, discussing their origins and how they are linked to Generators. Next, we will look at Tasks, which are a higher-level abstraction built on top of Coroutines. Tasks make it easy to schedule and manage the execution of Coroutines. We will cover how to create and manage Tasks and how they can be used to write concurrent code. Finally, we will also cover some more advanced topics such as Async Loops and Context Managers, and how to handle errors and cancellations in asyncio. Whether you are new to asyncio or have experience with it, this talk will provide valuable insights and tips for leveraging its full potential.

In 2009, it pushed the boundaries of what then-new technologies could do. What have the mappers learned over the years? This talk will welcome you to Nairobi and through the ups and downs of mapping in Kenya - from the history of mapping in 20th Kenya, through Map Kibera’s start, into slums and rural parts of Kenya, and finally to current-day Kibera, where mappers are mapping street lights, waste disposal, schools, and more. How has Map Kibera and OSM had a community impact even as drones, satellite technology and AI are revolutionizing mapping? What has changed, and what has remained the same? We will discuss the global impact of Map Kibera, on community-based mapping in OSM and on the general application of technology in developing countries. This talk will include a discussion of mapping in Kenya dating back to the colonial era, the establishment of Kibera as a region of Nairobi, and its growth into a massive informal settlement. Kibera has been viewed as a place to develop by the Kenya government, International aid agencies, charities, and missionaries. It was a flashpoint of the post-election violence of 2007/8. Map Kibera’s Kenyan leaders will discuss the most recent mapping and local impacts made by the use of OSM. Mapping of street lights in Kibera led to new and more street lights installed in Kibera. Mapping of waste management in Mukuru led to the placement of dumping waste bins. Data on schools has led to a pilot project to install solar panels on selected schools. None of these impacts have been easy, but we will share lessons learned about OSM, open data and communities. Finally, we conclude with a discussion of emerging and ever-changing technology, and the fate of the techno-optimism of the early 21st century.

An Computertechnik im Heimbereich war noch lange nicht zu denken. Der Fernseher war mittlerweile dank Ralph Baer als Massenmedium etabliert. Die Erzeugung fixer Objekte auf dem Screen war den Umständen entsprechend aufwandsarm, aber wie bewegte man ein Objekt, also vorzugsweise den Ball? Analoge Spiele nutzten den näherungsweise linear verlaufenden Teil der Lade- bzw. Entlade-Kurve eines Kondensators. Für die digitalisierten Spiele musste man sich etwas Aufwandsarmes einfallen lassen. Die späteren Atari-Gründer N. Bushnell und T. Dabney haben das getan. Allerdings gibt es kaum eine Beschreibung dessen. Die außerordentlich geniale Lösung kommt lediglich mit zwei Binärzählern aus. Der Vortrag befasst sich mit den Erläuterungen dazu.

Als Spielleitung wollen sowohl die Spielrunde als auch das Publikum abgeholt werden, doch die Erwartungen und Bedürfnisse dieser beiden Gruppen sind unterschiedlich. Also bleibt die Frage am Ende des Tages: Handeln wir authentisch? Und was ist das eigentlich…?! Jahrelang Rollenspieler, plötzlich Podcaster. Erst wirkt es identisch, so als würde man bei der üblichen Rollenspielrunde einfach ein Mikro dazustellen. Doch Moment mal, was ist so ein Pen-and-Paper-Rollenspiel eigentlich? Gemeinsam wird hier eine Abenteuergeschichte erzählt, in der die Gruppe einzelne Personen und deren Fähigkeiten und Träume ausspielen. Ziel ist die Erzählung einer spannenden und interessanten Geschichte, über die man gemeinsam fachsimpeln und scherzen kann. Als Spielleiter, der die Rahmenhandlung gestaltet, ist es manchmal gar nicht so einfach, der gesamten Runde gerecht zu werden. Mit einem Podcast-Publikum ist jedoch plötzlich alles anders: Nicht nur der Handvoll Personen am Tisch soll nun eine interessante Geschichte erzählt werden, sondern auch einer unüberblickbar großen Anzahl an Ohren quer in Deutschland und der Welt. Wir berichten von unseren Erfahrungen damit, dem großen Rätsel der Authentizität – und unserer Antwort darauf.

In this 45-minute workshop, you’ll get a comprehensive, hands-on experience in setting up your own Castopod server and learn how to publish your podcast. We’ll dive into the platform’s intuitive interface, exploring how to upload episodes, manage your RSS feed, and customize your podcast’s public page. We’ll also touch on advanced features like integrating with Mastodon and other Fediverse platforms, enabling you to directly engage with your audience in a decentralized environment. This workshop is ideal for podcasters, developers, and tech enthusiasts who are eager to gain the skills needed to self-host and take full ownership of their podcasting content. By the end of the session, you’ll have a fully operational Castopod instance and the knowledge to maintain and grow your podcast independently.

Wir wollen einen Blick darauf werden, warum diese Struktur besonders für Podcaster:innen von Vorteil sein kann und das gleich auf mehreren Ebenen: Statt sich auf zentrale Plattformen zu verlassen, eröffnet das Fediverse neue Wege für die unabhängige und nachhaltige Verbreitung von Inhalten. Die Kommunikation im Fediverse läuft nicht über einzelne, große Anbieter – sondern verteilt sich auf viele kleine, miteinander verbundene Instanzen. Das gibt Podcaster:innen mehr Kontrolle über die Art und Weise, wie sie mit ihrem Publikum in Kontakt treten. Auch das Hosting von Podcasts wird durch die dezentrale Struktur flexibler und ermöglicht eine größere Unabhängigkeit von kommerziellen Plattformen. Wir zeigen außerdem, wie das Fediverse nicht nur ein Raum für neue Netzwerke bietet, sondern auch eine Antwort auf die Herausforderungen der zunehmend zersplitterten, datenkapitalistischen Social-Media-Landschaft sein kann. Gänzlich durch die rosa Brille schauen wollen wir hier aber auch nicht: Viele Strukturen sind noch ausbaufähig, die Anzahl der User:innen wächst eher schleppend und für viele Menschen gibt es ziemlich viele Einstiegshürden. Welche Potenziale wir noch ausschöpfen könnten und was es dafür braucht – darüber wollen wir mit euch diskutieren.

Enter Castopod, an open-source podcast hosting platform that seamlessly integrates with the Fediverse, offering unprecedented autonomy and connection in the world of podcasting.

Diese Ausgangslage führte auch zur Gründung von wissenschaftspodcasts.de, ein großes Angebot mit dutzenden Podcasts aus dem Wissen(schaft)sbereich, die sich Hörer:innen in einem „Warenkorb“ zusammenstellen können. Zudem findet schon seit 2013 jährlich das Treffen der Wissenschaftspodcaster:innen, GanzOhr, statt. Auf der Plattform wissenschaftspodcasts.de haben sich im letzten Jahrzehnt rund 360 Podcasts aus dem Wissen- und Wissenschaftsbereich versammelt. Alle diese Podcasts haben eine Kuration durchlaufen, die von einem insgesamt bis zu 10-köpfigen Redaktionsteam gestemmt wird. Neben der inhaltlichen Seriosität spielt auch die Form der Zugänglichkeit eine wichtige Rolle: Nur Angebote mit offen zugänglichem RSS-Feed können für die Aufnahme in das Projekt in Erwägung gezogen werden. In der Wissenschaftskommunikation sind Podcasts inzwischen ein etabliertes Kommunikationsmedium, gerade auf institutioneller Ebene geradezu Standard geworden. Nicht zufällig waren Podcasts und Wisskomm rasch ein beliebtes Team. In diesem Workshop wollen wir daher nicht nur der Frage nachgehen, was Podcasts für die Wissenschaft „getan“ haben, sondern auch wie das Format zurückwirkt: Wie hat das kreative, offene Format der Podcasts den Blick auf gelungene Wissenschaftskommunikation verändert? Welche Rolle haben Wissenschaftler:innen durch dieses neue Sprachrohr in der Gesellschaft erlangen können? In diesem Workshop wollen wir einen Blick hinter die Kulissen dieses Projekts gewähren und von unseren Erfahrungen mit jahrelanger Kuration erzählen. Was funktioniert gut, woran sind wir vielleicht auch gescheitert – und wie kann bzw. soll es weitergehen? Der Workshop soll Raum für Austausch für Wissen(schaft)spodcaster:innen und natürlich auch Hörer:innen bieten.

In diesem Talk dreht es sich um die 10 Dinge, die ich nach einem Jahr und hundert Folgen gelernt habe. Ein Talk für alle, die auch eine Podcast-Idee haben und nicht wissen, was auf sie zu kommt, aber danach sofort loslegen möchten. Wie fängt man an? Was tun, wenn Gäste kein eigenes Mikrofon haben aber auch keinen Computer? Was, wenn man im Hotel zum Interview verabredet ist, aber niemand davon weiß? Sind drei Backups zu viel? Wie bleibt man Freunde, wenn man 60 Stunden miteinander redet? Wie erklärt man der größten Medienagentur Deutschlands, dass das alles doch nur eine Schnapsidee ist? Wie fühlt es sich an, plötzlich beim größten Comedy-Festival dabei zu sein, weil die nicht wissen, dass man nur 500 Hörer*innen hat? Mit zwei Freund*innen hatte die Idee, die Komödie "Kein Pardon" von 1993 Minute für Minute zu besprechen. Was nach einer witzigen Idee klingt, wurde zu einem harten Ritt.

Ultraschall ist ein Open-Source-Projekt, das seit fast 11 Jahren auf der Digital Audio Workstation (DAW) REAPER aufbaut und speziell für die Bedürfnisse von Podcastern entwickelt wurde. Während viele DAWs hauptsächlich für die Musikproduktion konzipiert sind, bietet Ultraschall eine angepasste Benutzeroberfläche und Funktionen, die den gesamten Prozess des Podcastings vereinfachen.

Ultraschall ist ein Open-Source-Projekt, das seit fast 11 Jahren auf der Digital Audio Workstation (DAW) REAPER aufbaut und speziell für die Bedürfnisse von Podcastern entwickelt wurde. Während viele DAWs hauptsächlich für die Musikproduktion konzipiert sind, bietet Ultraschall eine angepasste Benutzeroberfläche und Funktionen, die den gesamten Prozess des Podcastings vereinfachen.

Es gibt mittlerweile innovative Lösungen für Probleme, die es vor einiger Zeit noch gar nicht gab. Doch sogar mit immer intelligenteren Tools zeigt sich, dass es kein universelles Allheilmittel gibt – keine "One-Size-fits-all"-Lösung für die Audiopostproduktion. Bei Auphonic stehen wir täglich vor der Herausforderung automatisierte Lösungen für einzigartige Audio-Probleme zu finden. Hier zeigen wir euch unsere Lösungen sowie offene Fragen und Probleme, mit denen wir konfrontiert sind. Wir werden verschiedene Anwendungsfälle präsentieren, zeigen wie unsere KI-Tools optimal genutzt werden können, was bei der Entwicklung und dem Training von Modellen zu beachten ist und welche Prinzipien für unterschiedliche Kontexte wie Musik, Sprache, Atmosphäre und Soundeffekte wichtig sind. Wir zeigen euch einen kleinen Abriss über die Geschichte der Audio Postproduktion, wann und wo Auphonic entstanden ist, was wir gerade machen und wie ihr unsere Tools optimal nutzen könnt.

Ein besonderes Merkmal: Das Podstock ist nicht kommerziell und gewinnorientiert, die Preise bezahlen nur die Unkosten.

Die RiffReporter bieten eine Antwort auf diese Krise: In der 2017 gegründeten Genossenschaft haben sich über hundert Journalistïnnen zusammengeschlossen. Sie recherchieren und schreiben zu aktuellen Themen: dem Weltgeschehen, Umwelt, Klima oder Technik. Es sind viele Recherchen dabei, die aktuelle Themen in großer Tiefe ausleuchten.

Du möchtest prominente Gäste/vielbeschäftigte Expert*innen für Deinen Podcast gewinnen und weißt nicht genau, wie Du das anstellen sollst? Du willst längere Gespräche führen und bist Dir unsicher, wie Du die Gespräche strukturieren willst und wie stark Du Dich überhaupt vorbereiten sollst? Ich zeige Dir, wie Du E-Mails so formulierst, dass die Chancen für eine positive Antwort steigen und wie Du Dein Gespräch so vorbereitest, dass Du spontan sein kannst und Dich dennoch nicht verlierst. Bringe gerne Beispiele für eine Person mit, die Du zu einem bestimmten Thema anfragen möchtest und dann entwickeln wir gemeinsam eine Anfrage und eine Gesprächsstruktur. Mein Hintergrund: Ich habe nach einem Volontariat 12 Jahre beim Hessischen Rundfunk gearbeitet, überwiegend als Redakteurin und Moderatorin, u.a. für die monothematische Politsendung "Der Tag". Von 2012 bis 2024 war ich Pressesprecherin der Europa-Universität Flensburg. Seit zwei Jahren hoste ich den Podcast "Erschöpfung statt Gelassenheit - warum Achtsamkeit die falsche Antwort auf so ziemlich jede Frage ist". Seit Juli 2024 arbeite ich freiberuflich als Podcasterin, Autorin und Moderatorin. Von Beginn meines beruflichen Daseins an musste ich Menschen darum bitten, bei irgendetwas mitzumachen: Ein Interview geben, für einen Beitrag zur Verfügung stehen, als Künstler*in auftreten, eine Kooperation eingehen etc. Meine Erfolgsquote ist recht hoch - ich erkläre mir das mit den sorgfältig aufgesetzten, transparenten, informativen und fokussierten Anfragen, die ich versende. Mein Podcast besteht aus einem Gespräch von bis zu 2 Stunden - schon bei HR2/Kultur habe ich am liebsten längere Gespräche geführt. Ich habe viele Fortbildungen zu Gesprächsführung besucht und glaube mittlerweile, dass gute Vorbereitung, aufmerksames Zuhören, die Bereitschaft, sich selbst zu zeigen und die Fähigkeit, sich mittels einer klaren Fragestellung auch auf unübersichtlichem Gelände zurechtzufinden, unabdingbare Voraussetzungen für ein gelungenes Gespräch sind.

Einrichtungen des Gesundheitswesens müssen die Sicherheit der Patienten in jeder Phase der Behandlung gewährleisten. In der heutigen digitalisierten Welt stehen Krankenhäuser vor einzigartigen Herausforderungen in Bezug auf die IT-Infrastruktur und die Cybersicherheit. In dieser Präsentation geben wir einen Überblick über die Komplexität und den Umfang der IT- und Medizingerätelandschaft in modernen Krankenhäusern und bieten einzigartige Einblicke in die wichtigsten Sicherheitsherausforderungen einer der größten Gesundheitsorganisationen in Deutschland. Unser Vortrag wird sich auf die Sicherheitsherausforderungen konzentrieren, denen Krankenhäuser und medizinische Versorgungszentren als Betreiber öffentlicher Gesundheitsdienste gegenüberstehen. Wir möchten organisatorische Faktoren hervorheben, die die Komplexität erhöhen, wie z.B. begrenzte Budgets, verteilte Verantwortlichkeiten, Politik und Einstellungsschwierigkeiten im Wettbewerb mit anderen Branchen, die weniger komplexe Probleme, aber mehr finanzielle Ressourcen haben. Wir möchten die offensichtlichen Herausforderungen beleuchten, die verschiedene Technologien und Infrastrukturen für Krankenhäuser bei der Erbringung ihrer Dienstleistungen darstellen. So unterstützen Software und Infrastrukturen medizinische Prozesse wie Abrechnungs- und Verwaltungssysteme, die für die Verwaltung und Unterstützung der medizinischen Versorgung von entscheidender Bedeutung sind, aber nicht direkt mit der Behandlung zu tun haben. Diese Software ist typisch für den Gesundheitssektor, aber vergleichbar mit der normalen IT-Infrastruktur von Unternehmen.

Einrichtungen des Gesundheitswesens müssen die Sicherheit der Patienten in jeder Phase der Behandlung gewährleisten. In der heutigen digitalisierten Welt stehen Krankenhäuser vor einzigartigen Herausforderungen in Bezug auf die IT-Infrastruktur und die Cybersicherheit. In dieser Präsentation geben wir einen Überblick über die Komplexität und den Umfang der IT- und Medizingerätelandschaft in modernen Krankenhäusern und bieten einzigartige Einblicke in die wichtigsten Sicherheitsherausforderungen einer der größten Gesundheitsorganisationen in Deutschland. Unser Vortrag wird sich auf die Sicherheitsherausforderungen konzentrieren, denen Krankenhäuser und medizinische Versorgungszentren als Betreiber öffentlicher Gesundheitsdienste gegenüberstehen. Wir möchten organisatorische Faktoren hervorheben, die die Komplexität erhöhen, wie z.B. begrenzte Budgets, verteilte Verantwortlichkeiten, Politik und Einstellungsschwierigkeiten im Wettbewerb mit anderen Branchen, die weniger komplexe Probleme, aber mehr finanzielle Ressourcen haben. Wir möchten die offensichtlichen Herausforderungen beleuchten, die verschiedene Technologien und Infrastrukturen für Krankenhäuser bei der Erbringung ihrer Dienstleistungen darstellen. So unterstützen Software und Infrastrukturen medizinische Prozesse wie Abrechnungs- und Verwaltungssysteme, die für die Verwaltung und Unterstützung der medizinischen Versorgung von entscheidender Bedeutung sind, aber nicht direkt mit der Behandlung zu tun haben.

Das ganze soll sich anfühlen wie ein Etherpad, aber für ganze Projekte, auf dem lokalen Dateisystem, und mit Neovim, VS Code, oder euren anderen Lieblings-Texteditoren! Wir sprechen über unsere Vision, die technische Umsetzung, und über Herausforderungen, auf die wir dabei stießen. Mit Software wie Etherpad oder Hedgedoc zusammenzuarbeiten fühlt sich ein bisschen an wie Magie: Man kannst sofort sehen, was andere gerade tippen. Der Nachteil ist, dass man online sein muss, um auf den Inhalt zuzugreifen – da das Dokument auf einem Server liegt, ist es verschwunden, sobald man die Verbindung trennt. Wir arbeiten an einer Open-Source-Software namens "Ethersync", um Echtzeit-Kollaboration ins Dateisystem zu bringen! Wir wollen es möglich machen, zusammen Notizen und Dokumentation zu schreiben, und denken auch an Use-Cases wie Pair-Programming – direkt in Neovim, VS Code oder vielleicht bald auch in eurem Lieblingseditoren. Wir folgen dabei dem "Local-First"-Ansatz, bei dem man immer die Kontrolle über die Daten behält, da sie auf der eigenen Festplatte gespeichert sind. In diesem Vortrag möchten wir unsere Vision für diese Art der Zusammenarbeit erläutern und euch unseren Fortschritt und unseren aktuellen Prototypen zeigen. Wir möchten einige der Probleme erklären, auf die wir dabei gestoßen sind, und auf die zugrundeliegende Technologie eingehen (wie Conflict-Free Replicating Data Types und Operational Transform). Denn wie sich herausstellt, ist dies ein schwer zu lösendes Problem.

But we are still a long way from having a generative AI that does what it suggests. Die generative KI ist eine mehr als beeindruckende Technologie. Aber wir sind noch weit davon entfernt, eine generative KI zu haben, die tut, was sie vorschlägt. Algorithms write source code, compose pieces of music, write scientific articles. But they guarantee neither quality nor functionality, let alone authenticity. AI knows neither true nor false nor right and wrong - which is why it cannot lie, but can "hallucinate". AI tries to "please" like a student who tries to give a plausible answer that pleases his teacher to a question that he cannot answer. AI does not care about ethical or legal issues. If it is not "tamed", it can become a danger that can no longer be controlled. Generative AI can destroy livelihoods - be it through "hallucinated information about people., or in the military sector, where it already plays a far greater role than assumed. Generative AI not only optimizes logistics and production processes. Generative AI can also take over military strategic planning and direct military operations, from acts of sabotage (blocking GPS) to the independent selection of targets and the choice of appropriate weapon systems. Algorithms are also increasingly contributing to business decisions in the economy. From automated application processes to portfolio strategies and marketing campaigns. This scenario has yet to be fully realized - humans still make the final decision - but for how much longer? The speaker will attempt to explain clearly why generative AI is neither intelligent nor creative, and why algorithms may take on the role of co-pilot, even autopilot, but never the role of flight captain. Algorithmen schreiben Quellcode, komponieren Musikstücke, verfassen wissenschaftliche Artikel. Aber sie garantieren weder Qualität noch Funktionalität, geschweige denn Authentizität. KI kennt weder wahr noch falsch noch richtig und falsch - deshalb kann sie auch nicht lügen, aber "halluzinieren". KI versucht zu "gefallen", wie ein Schüler, der versucht, auf eine Frage, die er nicht beantworten kann, eine plausible Antwort zu geben, die seinem Lehrer gefällt. Die KI kümmert sich nicht um ethische oder rechtliche Fragen. Wenn sie nicht "gezähmt" wird, kann sie zu einer Gefahr werden, die nicht mehr kontrolliert werden kann. Generative KI kann Existenzen zerstören - sei es durch "halluzinierte Informationen über Menschen", sei es im militärischen Bereich, wo sie bereits eine weitaus größere Rolle spielt als angenommen. Generative KI optimiert nicht nur Logistik- und Produktionsprozesse. Generative KI kann auch die militärische Strategieplanung übernehmen und militärische Operationen steuern, von Sabotageakten (Blockieren von GPS) bis hin zur eigenständigen Auswahl von Zielen und der Wahl geeigneter Waffensysteme. Auch in der Wirtschaft tragen Algorithmen zunehmend zu Geschäftsentscheidungen bei. Von automatisierten Bewerbungsverfahren bis hin zu Portfoliostrategien und Marketingkampagnen. Dieses Szenario ist noch nicht vollständig realisiert - noch trifft der Mensch die letzte Entscheidung - aber wie lange noch? Der Referent wird versuchen, anschaulich zu erklären, warum generative KI weder intelligent noch kreativ ist und warum Algorithmen zwar die Rolle des Co-Piloten, sogar des Autopiloten, aber niemals die Rolle des Flugkapitäns übernehmen können. https://creativecommons.org/licenses/by-sa/4.0/ about this event: https://talks.mrmcd.net/2024/talk/U8T9QL/ </description> <enclosure url="https://cdn.media.ccc.de/events/mrmcd/mrmcd24/h264-hd/mrmcd24-381-deu-Besser_natuerlich_dumm_als_kuenstlich_intelligent_Ueber_Generative_KI_-Sie_werden_enttaeuscht_sein_hd.mp4" length="781189120" type="video/mp4"/> <pubDate>Sat, 05 Oct 2024 12:00:42 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/mrmcd/mrmcd24/h264-hd/mrmcd24-381-deu-Besser_natuerlich_dumm_als_kuenstlich_intelligent_Ueber_Generative_KI_-Sie_werden_enttaeuscht_sein_hd.mp4?1728138694</guid> <dc:identifier>369680bd-6cf5-5e34-9a3d-b7b1a90e9eec</dc:identifier> <dc:date>2024-10-05T12:00:42+02:00</dc:date> <itunes:author>Uli Kleemann</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>381, Darmstadt, mrmcd24, mrmcd24, C205 - Ocean Starr, 2024, Day 3</itunes:keywords> <itunes:summary>Summary: Generative AI is a more than impressive technology.

Die KI kümmert sich nicht um ethische oder rechtliche Fragen. Wenn sie nicht "gezähmt" wird, kann sie zu einer Gefahr werden, die nicht mehr kontrolliert werden kann. Generative KI kann Existenzen zerstören - sei es durch "halluzinierte Informationen über Menschen", sei es im militärischen Bereich, wo sie bereits eine weitaus größere Rolle spielt als angenommen. Generative KI optimiert nicht nur Logistik- und Produktionsprozesse. Generative KI kann auch die militärische Strategieplanung übernehmen und militärische Operationen steuern, von Sabotageakten (Blockieren von GPS) bis hin zur eigenständigen Auswahl von Zielen und der Wahl geeigneter Waffensysteme. Auch in der Wirtschaft tragen Algorithmen zunehmend zu Geschäftsentscheidungen bei. Von automatisierten Bewerbungsverfahren bis hin zu Portfoliostrategien und Marketingkampagnen. Dieses Szenario ist noch nicht vollständig realisiert - noch trifft der Mensch die letzte Entscheidung - aber wie lange noch? Der Referent wird versuchen, anschaulich zu erklären, warum generative KI weder intelligent noch kreativ ist und warum Algorithmen zwar die Rolle des Co-Piloten, sogar des Autopiloten, aber niemals die Rolle des Flugkapitäns übernehmen können. https://creativecommons.org/licenses/by-sa/4.0/ about this event: https://talks.mrmcd.net/2024/talk/U8T9QL/ </itunes:summary> <itunes:duration>00:53:21</itunes:duration> </item> <item> <title>Wie entsteht eigentlich ein Fahrplan?

Dazu muss man lediglich das bereitgestellte Proxmox Image bei der Installation aus dem Rescue System auswählen. Etwas herausfordernder wird es, wenn man mehrere virtuelle Server auf Proxmox installieren und dem Rest der Welt zugänglich machen will - was ja vermutlich der Grund für die Auswahl und Installation von Proxmox war. Bei einem Proxmox im Heimnetzwerk ist es recht simple: Man gibt dem Dienst einfach eine freie IP-Adresse aus dem verwendeten privaten Netzwerk. Bei einem Internetanbieter muss ich üblicherweise für jeden per IPv4 erreichbaren Dienst eine IP Adresse dazu kaufen. Das kann schnell teuer werden. Und bei einigen Anbietern bekomme ich auch nur eine begrenzte Anzahl an IPv4 Adressen. Eine kostengünstige Variante ist, die virtuellen Server mit privaten Adressen zu versorgen und auf dem Host zu natten (Destination NAT). Für die Weiterleitung an das richtige Ziel kann man zum Beispiel VyOS (virtueller Router) oder den NGINX Proxymanager verwenden. Ihr ahnt es bereits - wir verwenden hier den NGINX Proxymanager. Die Youtube Videos zu diesem Thema hatten mich damals nicht überzeugt beziehungsweise waren die Lösungen nicht skalierbar. Aus diesem "Mangel" heraus ist dieses Setup und diese Konfiguration entstanden. Ich verwende sie inzwischen seit mehreren Jahren für Trainings und Workshops für Cyber Security Professionals. Auch meine eigenen Server betreibe ich nach dieser Art ohne Probleme. In diesem Talk werden wir auf einem Hetzner Dedicated Server ein Proxmox System von Scratch installieren, das bedeutet: - Booten in das Rescue System - Auswahl des Images - Konfigurieren des Setup Scripts (installimage) - Update von Proxmox auf die aktuelle Version - anpassen der Proxmox Netzwerkkonfiguration (mehrere Netzwerke) - Einbinden der Hetzner Storagebox - Instalaltion einiger Server und Dienste - Konfiguration des DNS - Installation und Konfiguration des NGINX Proxymanagers Dieser Talk ist als Demo angelegt. Ich werde alle Schritte live ausführen und am Ende werden wir eine funtkionierende Proxmox Installation mit internen Netzwerken und NGINX Proxymanger haben.

Deriving correct results is crucial to ensure reliable decision-making, leading to better outcomes in business, healthcare, governance and daily life. Yet, in data science we frequently encounter a makeshift approach, where various tools are tied together with untested procedural glue code. This talk explores the benefits of applying functional programming principles in data science. Emphasising immutability, pure functions and the benefits of strong type systems, we demonstrate how these concepts lead to more reliable and maintainable data workflows. Practical examples will showcase improved code clarity, verifiable specifications, parallel processing capabilities and simplified debugging. Learn how integrating functional programming techniques can transform your data science practices, resulting in more predictable and reproducible outcomes.

Der vor über 40 Jahren entwickelte CAN-Bus (Controller Area Network) ist ein serieller Feldbus für den Datenaustausch zwischen elektronischen Steuergeräten (ECUs) in der Automobiltechnik und der Fabrikautomation. Weitere Einsatzgebiete sind zwischen Ladestationen und Elektrofahrzeugen, in E-Scootern und E-Bikes oder in der Hausautomation/Solarreglern. Viele interessante Endgeräte und zum Teil proprietäre Protokolle die untersucht, Reverse Engineered oder gefuzzed werden wollen. Hier setzt SocketCAN an, eine seit über 15 Jahren im mainline Linux Kernel integrierte Unterstützung für CAN Hardware, die es ermöglicht über die bekannte Socket Schnittstelle CAN Nachrichten zu verschicken und zu empfangen. Der Talk klärt die dringendsten Frage, wie kann ich mit CAN loslegen, welche Hardware wird unterstützt.

Der vor über 40 Jahren entwickelte CAN-Bus (Controller Area Network) ist ein serieller Feldbus für den Datenaustausch zwischen elektronischen Steuergeräten (ECUs) in der Automobiltechnik und der Fabrikautomation. Weitere Einsatzgebiete sind zwischen Ladestationen und Elektrofahrzeugen, in E-Scootern und E-Bikes oder in der Hausautomation/Solarreglern. Viele interessante Endgeräte und zum Teil proprietäre Protokolle die untersucht, Reverse Engineered oder gefuzzed werden wollen. Hier setzt SocketCAN an, eine seit über 15 Jahren im mainline Linux Kernel integrierte Unterstützung für CAN Hardware, die es ermöglicht über die bekannte Socket Schnittstelle CAN Nachrichten zu verschicken und zu empfangen. Der Talk klärt die dringendsten Frage, wie kann ich mit CAN loslegen, welche Hardware wird unterstützt. Außerdem erläutert er die Grundlagen des CAN Buses, geht auf Gemeinsamkeiten und Unterschiede im Vergleich zu Ethernet ein. Angesprochen werden die vom Kernel unterstützten CAN Protokolle (CAN-Raw, ISO-TP, J1939). Ferner werden eine Reihe von Standard CAN Tools vorgestellt, z.B. zum aufzeichnen/abspielen/analysieren von CAN Traffic. https://creativecommons.org/licenses/by-sa/4.0/ about this event: https://talks.mrmcd.net/2024/talk/GHYGXC/ </itunes:summary> <itunes:duration>00:30:28</itunes:duration> </item> <item> <title>Designing PCBs with Python: faebryk (mrmcd24)</title> <link>https://media.ccc.de/v/2024-400-designing-pcbs-with-python-faebryk</link> <description>[faebryk](https://github.com/faebryk/faebryk) is an open source Python library for electronic design automation (EDA).

Konkrete Themen sind unter anderem: - automatische Updates - Reboots nach Kernelupdates - Backups - Configmanagement - Monitoring all dieser Tasks - (Geo-)Redundanz - Kubernetes!? - Was man noch so alles tun müsste https://creativecommons.org/licenses/by-sa/4.0/ about this event: https://talks.mrmcd.net/2024/talk/BMFXS9/ </itunes:summary> <itunes:duration>00:31:39</itunes:duration> </item> <item> <title>Schiffe erkennen leicht gemacht (mrmcd24)</title> <link>https://media.ccc.de/v/2024-351-schiffe-erkennen-leicht-gemacht</link> <description>Nach einer Vorstellung des AIS (Automated Identification System), mit dem fast alle Schiffe Position, Fahrt usw. mitteilen müssen, gehe ich noch detaillierter auf verschiedene Punkte des verwendeten AIS-Protokolls ein.

Initially separate, it now is part of mkosi — just another build stage. systemd uses mkosi for automated tests, and this now includes building an initrd and booting a VM with it, so such initrds are getting fairly wide testing, albeit in fairly narrow circumstances.

Initially separate, it now is part of mkosi — just another build stage. systemd uses mkosi for automated tests, and this now includes building an initrd and booting a VM with it, so such initrds are getting fairly wide testing, albeit in fairly narrow circumstances. The process of adoption of mkosi-initrd in distributions has been slow, but with an implementation natively in mkosi, the technical base is really good.

Traditionally, RAUC focused on A/B updates for whole partitions, either by using filesystem images or tar archives. While the image-based OS approach has many benefits, there are scenarios where more loosely coupled components need to be handle in addition to the root filesystem. In RAUC, these can be handled with using the new "artifact updates" support. As a system might have many artifacts installed in parallel, such as for containers (systemd-nspawn or otherwise) and systemd-sysexts, efficient storage is important. In many cases, these are updated often, so download efficiency is important as well. After evaluating multiple alternatives, we've now decided to integrate composefs. Besides solving the requirements above, it additionally provides the same level of integrity protection as a dm-verity root filesystem, which is important in systems using secure boot. This talk will show how RAUC uses libcomposefs and the new use-cases supported by having an efficient content-addressed backing store with full authentication.

Using openSUSE Tumbleweed as an example, I will show where and how it makes sense for traditional Linux distributions to use it and where the pitfalls are. With openSUSE MicroOS, we have a distribution with a read-only root file system that particularly benefits from a soft-reboot because a reboot is necessary after every update in order to change the root file system. However, this also requires special measures to ensure that it always functions smoothly. Afterwards I will talk about the requirements and solutions for services to survive a soft reboot and what's necessary to make the whole thing supportable.

GNOME OS is currently using OSTree, this talk covers the ongoing work to add features to systemd-sysupdate and transition to it. Features like optional transfers, delta updates, and major version upgrades. GNOME OS is an experimental Linux distribution that ships the latest in-development GNOME desktop, core applications, and stack. It serves as a reference for developers and testers. This operating system is designed and built around the modern systemd and GNU-based userland built from the Freedesktop SDK. Currently, GNOME OS uses OSTree to deploy the root filesystem and manage updates. This means that the base OS is immutable (read-only) and updates can be quickly downloaded as deltas. OSTree allows easy rollback to multiple previous versions of the root filesystem, which is essential for a testing-first distribution focused on finding bugs. Our work focuses on transitioning GNOME OS to use systemd-sysupdate. Migrating to sysupdate would bring the following benefits: * Provide a trust chain from the bootloader, all the way up, both online and offline; * Achieve a closer integration with systemd; * Advance our support for image-based design and its benefits, e.g., immutability, auto-updating, adaptability, factory reset, uniformity and other modernised security properties around image-based OSes. For that, we are adding a number of features to systemd-sysupdate to make it more production ready; * Implement optional transfers in systemd-sysupdate * sysupdate should allow upgrading to a newer major version * pluggable backends for systemd-sysupdate (or systemd-import) This project was partly inspired by Lennart Pottering's article "Brave New Trusted Boot World", in which he explains a vision of the future of Linux systems.

This talk will dive into how Meta baseline’s our systemd usage across the fleet and use that data for CI, releasing and monitoring systemd. * Who am I + what do I work on * The common big monitoring hole many bare bone infrastructures have * PID 1 * PID 1 usage * Systemd @ meta * Imaging initrd * Initrd * Main os * Twine containers * Overview of OS image building and deployment @ meta * How we build images * How we provision servers * Chef’s role * What we check from our PID1 statistics to ensure a box is “healthy” enough to take workloads * Usage of hyperscale’s systemd-cd @ meta * What is systemd-cd * [https://sigs.centos.org/hyperscale/internal/ci/](https://sigs.centos.org/hyperscale/internal/ci/) * How do we use it * What issues has it found for us * Monitoring of meta’s systemd usage across the millions of hosts * Stats collected * Introduce monitord * Dbus (fun) vs. varlink * mention OSS alternative(s) found - explain why invented monitord * Introduce monitord-exporter * Show usage outside of meta (will be my small home infra + VPS’s) Licensed to the public under https://creativecommons.org/licenses/by/4.0/de/ about this event: https://cfp.all-systems-go.io/all-systems-go-2024/talk/7APG3H/ </itunes:summary> <itunes:duration>00:37:21</itunes:duration> </item> <item> <title>Integration testing environment for mixed HPC and cloud workloads (asg2024)</title> <link>https://media.ccc.de/v/all-systems-go-2024-321-integration-testing-environment-for-mixed-hpc-and-cloud-workloads</link> <description>Integration testing environment for mixed HPC and cloud workloads Licensed to the public under https://creativecommons.org/licenses/by/4.0/de/ about this event: https://cfp.all-systems-go.io/all-systems-go-2024/talk/XNQLTE/ </description> <enclosure url="https://cdn.media.ccc.de/events/all_systems_go/2024/h264-hd/asg2024-321-eng-Integration_testing_environment_for_mixed_HPC_and_cloud_workloads_hd.mp4" length="25165824" type="video/mp4"/> <pubDate>Wed, 25 Sep 2024 18:15:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/all_systems_go/2024/h264-hd/asg2024-321-eng-Integration_testing_environment_for_mixed_HPC_and_cloud_workloads_hd.mp4?1727362522</guid> <dc:identifier>b867a151-17c0-5663-90e2-f89ee2aa03a4</dc:identifier> <dc:date>2024-09-25T18:15:00+02:00</dc:date> <itunes:author>Ruggero Lot</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>321, asg2024, Main Hall, 2024, Day 1</itunes:keywords> <itunes:summary>Integration testing environment for mixed HPC and cloud workloads Licensed to the public under https://creativecommons.org/licenses/by/4.0/de/ about this event: https://cfp.all-systems-go.io/all-systems-go-2024/talk/XNQLTE/ </itunes:summary> <itunes:duration>00:04:23</itunes:duration> </item> <item> <title>Debian, empty /var/, empty /etc/ and factory reset (asg2024)</title> <link>https://media.ccc.de/v/all-systems-go-2024-284-debian-empty-var-empty-etc-and-factory-reset</link> <description>This presentation will review how far Debian (and more generally, traditional distributions) is from supporting factory reset: what can work, what is missing and possible hacks^Wways to do it without starting a distribution-wide effort.

When you think about it, a container image is just a custom Linux distro. The distro (e.g. Alpine) is your base image and the customizations are the rest of your application or microservice. Like Podman, Yocto can generate a complete root filesystem in the form of an OCI container image. Originally targeted at bare metal, the Yocto configuration and build process seems complex when compared to the Containerfile approach of cloud native tools. Yocto's OpenEmbedded origins also mean that reduced image size, SBOM generation, license compliance, and reproducible builds were concerns early on in the project rather than afterthoughts.

Production environments, while offering high security and immutability, can inhibit rapid development cycles. Conversely, sandbox environments provide the flexibility and integration needed for fast development but are not suitable for production deployment. The transition between these two environments is typically fraught with challenges, consuming significant time and effort. This talk introduces Avocado Linux, a highly secure, image-based operating system and layer repository with deeply integrated developer tools. Avocado strikes a perfect balance between flexibility and immutability, combining the best of both worlds, accelerating time to market without compromising on security. By leveraging innovative systemd features like System Extensions, Configuration Extensions, and Portable Services, Avocado Linux provides a robust framework for service management, process isolation, and secure, atomic updates. Its design ensures robust security and system integrity, with comprehensive use of dm-verity and mechanisms for recovery and factory reset, safeguarding device data integrity even in the face of unexpected failures. Join us to explore how Avocado can transform your embedded systems development with faster integration, enhanced reliability, and seamless composability. Discover how this distribution delivers significant business value by enabling rapid deployment, maintaining security, and ensuring system integrity. Learn how Avocado abstracts away the complexities of system development, allowing your team and applications to thrive and your embedded product to scale and succeed.

We'll share insights into our methods, challenges faced, and solutions implemented, providing practical guidance for developers aiming to achieve reproducibility in their own projects. To achieve a fully reproducible stack, from the kernel and initramfs to the software we own and third-party software we build, we use multiple tools in our toolset: - Buildx: Provides a consistent environment for building software. - Kres: Our project scaffolding tool for generating and updating build instructions and dependencies. - Code Patches: Address issues in third-party projects that prevent reproducible builds. - Tests: Written by us to ensure and verify reproducibility. In this talk, we will cover each of these tools and techniques, providing examples and practical insights. You will learn how to apply these methods to achieve reproducible builds in your own projects, gaining a complete picture of our approach and how it can be adapted to your needs.

However, most of the used signing solutions either do not rely on hardware backed private key material or are run in untrusted environments. This presentation will provide a general overview of the [Signstar](https://gitlab.archlinux.org/archlinux/signstar/) project, which is currently under development by Arch Linux to provide a generic signing solution based on a Hardware Security Module (HSM). To improve build automation and general supply chain security for Arch Linux, some of its developers have started to conceptualize and work on a generic, central signing solution: [Signstar](https://gitlab.archlinux.org/archlinux/signstar/). In this context, related work has been evaluated for adoption, but it soon became clear, that to meet the distribution's requirements a custom solution would be implemented. For transparency and auditability reasons Nitrokey's NetHSM has been chosen as Hardware Security Module (HSM). Developers are actively working on a high-level Rust library and CLI to interface with the device over network. In this presentation I will introduce the viewer to some of Arch Linux's relevant history and requirements, the evaluated architecture and setup. Together we will have a look at Signstar's threat model, its design for minimizing credentials exposure of the HSM, as well as its integration with the OpenPGP ecosystem. Additionally, we will explore avenues for future work on other generic cryptographic operations in the context of X.509, SSH and Secure Boot.

It is the mechanism you'd use to communicate with many of the core Linux userspace subsystems, such as systemd, NetworkManager etc. Traditionally, most of these services have been written in C, a language known for its lack of safety and expressiveness. In the past years, Zeeshan has developed a library, called zbus for enabling implementation of D-Bus services and clients in a programming language designed for safety: Rust. zbus has become the go-to library for writing D-Bus code in Rust. While that is major step forward, the communication typically still happens through a broker and the two major broker implementation are both are written in C and have been stagnating for years. This is why Zeeshan has recently started working on writing a D-Bus broker based on zbus, called busd, which not only aims provide a drop-in replacement for existing brokers, but also modernize the D-Bus space by providing new features needed by apps and services, such as systemd. In this talk, Zeeshan will walk us through a summary of his journey so far, the current state of busd and his plans and dreams for the future of D-Bus.

The Varlink IPC has been around for a while, but recently we started using it heavily in systemd. In this talk I'd like to explain what Varlink IPC is, and why we are now adopting it so heavily. And I also want to explain why I think that Varlink is a good candidate as IPC of choice for any Linux software, both low-level and higher-level. We'll compare it with D-Bus in particular, and highlight where it shines (and where it doesn't shine so much).

The presentation will provide an introduction to the realm of confidential computing, as well as an overview of SPIFFE/SPIRE. Armed with this knowledge we will demonstrate a practical example that integrates the AWS Instance Identity Document plugin with AMD SEV-SNP, showcasing the implementation challenges and solutions. SPIFFE is a framework to generate identities for software systems in dynamic and heterogeneous environments. SPIFFE Verifiable Identity Documents (SVIDs) enable us to be explicit about the trust we place in systems. However, the degree of trust we can place in SVIDs relies heavily on the soundness of the data gathering and verification process during node attestation. This presentation introduces a novel approach to enhance the trust in SVIDs by leveraging confidential computing technologies, specifically Confidential Virtual Machines (CVMs) such as AMD SEV-SNP or Intel TDX. These technologies enable us to track platform information directly in hardware, including firmware, boot loader, and kernel images, which are then signed with a key rooted inside the CPU itself. By incorporating hardware-protected platform information directly into the SVID generation process, we can significantly enhance the confidence placed in the resulting identity documents. Additionally, consumers of these SVIDs will be able to assert these properties before placing trust in a system. The presentation will provide an introduction to the realm of confidential computing, as well as provide an overview of SPIFFE/SPIRE, including the architecture of SPIRE agents and servers, the concept of workloads and SPIFFE SVIDs, and the role of node plugins in the attestation process. A practical example that integrates the AWS Instance Identity Document plugin with AMD SEV-SNP will be demonstrated, showcasing the implementation challenges and solutions. Through this presentation, attendees will gain insights into how confidential computing technologies can bolster the security of critical systems in an untrusted cloud environment, paving the way for more robust and resilient infrastructure in modern computing environments.

Inspektor Gadget encapsulates eBPF programs into OCI containers, providing well-understood and easily distributable units. We then detail how an end user can use Inspektor Gadget to easily derive valuable systems insights. We'll give a brief overview of Inspektor Gadget's automatic data enrichment process, transforming complex kernel information into high-level, understandable concepts tied to Kubernetes and container runtimes. This feature bridges the knowledge gap between raw, low-level data and more interpretable information, improving the understanding of system behavior. We will explain how users can write their own gadgets and make use of different helper APIs provided by Inspektor Gadget for socket enricher, file path discovery and container filtering, etc. We will show how to combine existing gadgets into a new one, add additional post-processing logic using WASM or Lua and export the resulting data to different targets, using for example OpenTelemetry. Throughout the talk, we'll demonstrate more of Inspektor Gadget's features, its support across various environments, discuss its operational mechanics, and share insights into the future direction of the project.

To make updates safe and predictable, the system is mounted as read only and local modifications are discouraged. While containers offer a lot of flexibility on Linux, there are still cases where installing binaries or running applications directly on the host operating system is preferred. For example to add kernel modules, use an alternative container runtime version, add more udev rules, etc. Some of those use cases could be addressed with statically linked binaries, but their management is manual and their usage creates new issues around updates, versionning, memory footprint and not everything can be statically compiled. Alternatively, one can build its own image but at non-negligeable maintenance costs. Systemd's system extensions (sys-ext) provide a mechanism to extend the content of the host while preserving the safety guarentees around updates. We will demonstrate how Flatcar, Fedora CoreOS and Atomic Desktops are leveraging sysext images to securely extend the OS. With practical examples and usecases (e.g Cluster API) learn how to install Python, Podman, Kubernetes, ZFS, everything at the same time, by composing your very own image with systemd-sysext.

The Linux kernel is finally fixing an old proc/mem security bug which illustrates this trade-off nicely. The kernel will provide a mechanism, so distros need to implement a policy according to their own security needs, to restrict proc/mem access (it gives userspace RW access to processes memory). This talk goes into the what, why and how of getting this bug fixed, with some policies for plugging the long-standing hole for different use-cases, without breaking debuggers or container supervisors. This talk is based the Linux patch series [1] which is extending the /proc/*/mem access controls beyond the normal file-based permissions, to restrict various access during kernel builds (Kconfig level) or early boot via static/read-only key parameters. It is expected to land in kernel v6.11, to be released in late Q3 / early Q4 2024. The author is looking for opinions whether this should be backported to stable trees since the patch is somewhere between a bugfix and a new feature.

In this talk, we will explore the implementation of a new systemd service designed to enhance secure web token management through TPM 2.0 and FIDO2 support. This integration facilitates seamless interaction with the xdg-credentials-portal, aiming to provide a straightforward and secure approach to handling credentials. Key Points: Systemd Service Implementation: An in-depth look at how we are leveraging systemd to create a secure service for web tokens. TPM 2.0 and FIDO2 Integration: Understanding the role of TPM 2.0 and FIDO2 in enhancing hardware security. Seamless Integration with xdg-credentials-portal: Demonstrating the ease of use and benefits of integrating with the xdg-credentials-portal for secure credential management. New Functionality in Systemd: Discussing the significance of this new functionality and its potential impact on the systemd community. Targeted at systemd developers and enthusiasts, this session will provide valuable insights into the implementation process, the benefits of using TPM 2.0 modules for hardware security, and the overall enhancement of systemd functionalities. Attendees will leave with a clear understanding of the concepts and the practical steps required to integrate these security features into their own projects. Join us to explore the future of secure web tokens with systemd and how this integration can simplify and strengthen security protocols in your system architecture.

This enables an hybrid approach where the system is managed like an image but modifications are still possible using RPMs. But this approach has limits: - It is difficult for users to customize their operating system and share those customizations. - The integrity of the boot chain is not guarenteed and it is costly to validate the system content at runtime. To address those shortcomings, we are introducing the bootable containers (bootc) project. With bootable containers, the content of the operating system, including the kernel and initrd (or a UKI) is shipped in a container image alongside its corresponding base userspace root filesystem. This image can then be modified using container native tools and shared via a container registry. To chain from platform Secure Boot to a verified root filesystem, the ostree project has integrated support for composefs. It combines multiple Linux kernel features (overlayfs, EROFS and fs-verity) to provide read-only mountable filesystem trees stacking on top of an underlying "lower" Linux filesystem. We will detail how we are integrating composefs and UKI support in Bootable Containers to enable a trusted and measured boot chain while letting users customize and re-sign their images to fit their needs.

(DS2024)</title> <link>https://media.ccc.de/v/ds24-425-digital-fight-club-was-hat-das-netz-je-gutes-fr-uns-getan-</link> <description>In der 4. Auflage des DFC wollen wir mit Nele Hirsch die Protentiale des freien Internets feiern. „Das Internet“ erscheint uns häufig eher unter dem Blickwinkel von Problemen und Herausforderungen. Aber was ist eigentlich das Tolle, Gute und Schöne am Internet? Was bedeuten die Möglichkeiten der räumlichen und zeitlich unabhängigen Kommunikation und der Zugriff auf weltweites Wissen? Das Internet bietet unendliche Möglichkeiten der Kooperation und Kollaboration, des Teilens von Wissen und der Teilhabe. Aber diese Potenziale entfalten sich nur, wenn wir sie aktiv gestalten. In diesem Vortrag berichtet Nele Hirsch (freiberufliche Pädagogin im eBildungslabor) von ihren Erfahrungen mit dieser Herausforderung. Themen sind unter anderem das offene Teilen dank freien und offenen Bildungsmaterialien und Creative Commons, die Entwicklung eines Geschäftsmodells des Teilens mit freuen Lizenzen. Die Fallstricke einer mündigen Mediennutzung, die Vernetzung über das Fediverse (ein Zusammenschluss unabhängiger sozialer Netzwerke) und die Freuden eines eigenen Zuhauses im Internet mit einer eigenen Domain. Aufbauend auf dem Impuls ist Raum um gemeinsam zu diskutieren, wie wir gemeinsam eine Zukunft schaffen, in der freies Wissen und digitale Mündigkeit das Fundament für eine soziale, nachhaltige und demokratische Gesellschaft bilden. Vortrag mit Diskussionsrunde in der Reihe Digital Fight Club. Der Digital Fight Club ist ein Angebot an alle, die sich für die aktuellen netzpolitischen Themen und Entwicklungen interessieren, an einem regelmäßigen Austausch interessiert sind und sich gemeinsam für ein besseres Internet einsetzen möchten. Wir beginnen mit grundlegenden Informationsangeboten und Impulsvorträgen. Im Anschluss bleibt Raum für Fragen, einen gemeinsamen Austausch und Diskussion sowie ein gemeinsames Nachdenken darüber, welche (politischen) Handlungsperspektiven zu dem jeweiligen Themenbereich möglich sind und welche politischen Forderungen sich ableiten lassen. Die Impulsvorträge behandeln jeweils ein konkretes netzpolitisches Thema. Sie geben Einblick, ordnen ein und verdeutlichen Zusammenhänge. Dadurch werden die teilweise vielschichtigen Themen besser verständlich und Einflussmöglichkeiten der Zivilgesellschaft deutlich. Die Reihe ist eine Kooperation des Medienkulturzentrum Dresden e.V., der Sächsischen Landeszentrale für politische Bildung, der Landeszentrale für politische Bildung des Saarlandes, der Hessischen Landeszentrale für politische Bildung, der Landeszentrale für politische Bildung Rheinland-Pfalz und der Volkshochschule Dresden.

Wir stellen HowTheyVote.eu vor, eine quelloffene Plattform, auf der wir automatisiert Abstimmungsdaten aus dem Europäischen Parlament sammeln, sie mit weiteren Informationen kombinieren, übersichtlich darstellen und durchsuchbar machen. Dabei starten wir ausgehend von den verschiedenen offiziellen Datenquellen. Wir demonstrieren einige Fallstricke in Scraping-Projekten und im Umgang mit inkonsistenten Daten und ihrer Verknüpfung. Der Vortrag richtet sich an alle, die Interesse an der Arbeit des Europäischen Parlaments, an Web-Scraping-Projekten oder offenen Daten haben. Das Europäische Parlament ist die einzige unmittelbar demokratisch legitimierte der drei großen, gesetzgebenden EU-Institutionen. Im Juli ist das 10. Europäische Parlament mit 720 Abgeordneten zusammenkommen, die gemeinsam über 440 Millionen EU-Bürger*innen vertreten. Als Bürger*in selbst zu überprüfen, wie gut diese Vertretung klappt, ist leider schwierig: Zwar werden die Ergebnisse meistens inklusive Abstimmungsverhalten der einzelnen Abgeordneten veröffentlicht, aber sie sind schwer zu finden und nachzuvollziehen. Im Vortrag gehen wir kurz auf die grundlegende Rolle des Europäischen Parlaments im Europäischen Gesetzgebungsverfahren ein und schauen uns an, wie die veröffentlichten Abstimmungsdaten des Parlaments zu lesen sind. Danach geben wir einen Überblick, wie unsere automatisierte Sammlung und Aufbereitung technisch funktioniert. Dabei zeichnen wir nach, was wir seit unserem ersten Prototyp aus 2021 gelernt haben und versuchen Strategien für den Umgang mit unzuverlässigen Datenquellen an die Hand zu geben. Wir schließen mit einigen Ideen, wie unsere unter einer offenen Lizenz gesammelten Daten genutzt werden können.

Der europäische Gesundheitsdatenraum steht vor der Tür und es sieht zur Zeit nicht danach aus, dass wir mit dessen Umsetzung zufrieden sein können. Gesundheitsdaten aller europäischen Versicherten werden zentral gesammelt und nicht nur für die individuelle medizinische Versorgung gevorratsdatenspeichert, sondern auch für die Wissenschaft. Dabei ist hier explizit nicht nur akademische, sondern auch privatwirtschaftliche Wissenschaft gemeint. Das heißt, nicht nur Universitäten werden auf die Daten zugreifen können, sondern zum Beispiel auch die Pharmaindustrie und die ganz Großen wie Apple oder Google. Unter dem Vorwand der Verbesserung des Nutzungserlebnisses von proprietären Gesundheits-Apps (vorauseilende Mutmaßung der Speaker) werden die persönlichsten aller Daten in Hände gegeben, in denen sie wirklich nichts zu suchen haben.

In diesem Vortrag präsentieren wir, wie man mit Hilfe von probabilistischen Datenstrukturen personenbezogene Daten verarbeiten kann, ohne die Privatsphäre der jeweiligen Personen zu beeinträchtigen.

Die Meldung schlägt hohe Wellen, weil sie so realistisch klingt. Sie entpuppt sich als Aprilscherz - aber wer weiß das schon so genau? Ich will mal so sagen: Der Staat hält sich sehr zurück, um diesen Verdacht auszuräumen. In dem Vortrag stelle ich meine Überlegungen zum Thema vor, meine Erfahrungen mit den Finanzbehörden und zahlreiche IFG-Anfragen.

Kommen die besten und erfolgreichsten Projekte nicht aus Startups, Accelerators & Co.? Die letzten Jahre haben uns gezeigt, wohin es führen kann, alle Innovation mit Profitinteresse zu betreiben und Marktinteressen bestimmen zu lassen, wohin die Reise geht. Unsere Förderprojekte zeigen, dass es kein „Move fast and break things“ mit Millionen an VC braucht, um Neues und Sinnvolles zu schaffen. Wenn Einzelpersonen etwas entwickeln wollen, dann oft aus einem bestimmten Grund: Sie wollen ein reales Problem lösen, das sie selbst betrifft. Der Prototype Fund wurde 2016 gemeinsam mit dem BMBF ins Leben gerufen - schon damals mit der Idee, dass Menschen, die im Bereich Freier und Open Source Software einen meist unbezahlten aber wichtigen Beitrag für die Gesellschaft leisten, mehr Unterstützung und finanzielle Mittel brauchen. 8 Jahre und 14 Millionen Euro später läuft die geplante Förderperiode des Prototype Fund vorerst aus und wir können sagen: Wir haben viel gelernt! Weil wir fest davon überzeugt sind, dass der Prototype Fund kein Einzelfall bleiben soll, sondern als Blaupause für andere, ähnliche Fördertöpfe für die Zivilgesellschaft dienen kann, teilen wir unsere Lessons Learned für leichtgewichtige Förderstrukturen: Unkomplizierte Projektanträge, kurze Laufzeiten und 1:1-Betreuung sind nur einige der Zauberworte. Im Vortrag wollen wir Förder*innen ermutigen, sich aus ihrer Komfortzone zu bewegen und anzuerkennen, dass es für erfolgreiche Förderprojekte nicht immer 30 Seiten Antrag braucht, um die Zivilgesellschaft von innen heraus zu stärken. Wir wollen Menschen aus Behörden, Unternehmen und anderen Organisationen, die die Möglichkeit haben, Gelder zur Verfügung zu stellen, einen Einblick in die Strukturen von leichtgewichtigen Fördertöpfen geben. Und wir wollen zeigen: Strukturen für mehr Geld für die Zivilgesellschaft müssen nicht groß und komplex sein, um zu wirken.

In dieser praktischen Einführung laden wir Programme auf unsere Demo-Boards, schalten LEDs, nutzen Timer und greifen auf andere Boards über ein Funknetzwerk zu.

Auch unter Menschen, die grundsätzlich ähnliche Ziele haben (Demokratie stärken, in einem Projekt zusammenarbeiten, ...) verlaufen digitale Diskussionen oft unkonstruktiv oder sie eskalieren sogar. Das kostet Nerven und Ressourcen, die eigentlich dringend u. a. für die Verteidigung der FDGO gegen Totalitarismus und Klimastress gebraucht werden. Die Initiative für konstruktive digitale Diskussionskultur (<https://kddk.eu>) hat einen **konkreten Lösungsvorschlag**: Eine Selbstverpflichtung auf acht Regeln für konstruktives Diskutieren. Wenn ein eigener Beitrag diesen Regeln entspricht, kann er mit einem speziellen Hashtag gekennzeichnet werden (→ opt-in). Dadurch ist es möglich, mit Hilfe eines Tools "konstruktive" Beiträge herauszufiltern und somit unter den vielen anderen (mutmaßlich weniger relevanten) Beiträgen zu mehr Sichtbarkeit zu verhelfen. Mit anderen Worten: Durch diese gefilterte Ansicht verbessert sich das Signal-Rausch-Verhältnis erheblich, ohne dass dadurch Änderungen an der Plattform notwendig sind. Zum Ansatz gehören weiterhin Konzepte für Troll-Resilienz und verteilte Moderation sowie geeignete Anreizstrukturen. Das Ziel ist, plattformübergreifende virtuelle Räume zu etablieren in denen konstruktiv auch über kontroverse Themen diskutiert werden kann – und dadurch Lösungen für objektive Probleme zu finden.

Diese Einsicht hat vor zwei Jahren zur Gründung des Sovereign Tech Fund (STF) geführt. Die Organisation wird vom Bundesministerium für Wirtschaft und Klimaschutz finanziert und arbeitet an der Stärkung des Open Source Ökosystems im öffentlichen Interesse. Der Vortrag wird einen Einblick in die unterschiedlichen Instrumente geben, mit denen der STF arbeitet und auf die Initiativen eingehen, die aktuell pilotiert werden. Im Anschluss möchte ich die Frage in den Raum geben, welche anderen Perspektiven auf die beschriebene Herausforderung bestehen und welche Lösungen darüberhinaus denkbar sind.

Die Organisation wird vom Bundesministerium für Wirtschaft und Klimaschutz finanziert und arbeitet an der Stärkung des Open Source Ökosystems im öffentlichen Interesse. Der Vortrag wird einen Einblick in die unterschiedlichen Instrumente geben, mit denen der STF arbeitet und auf die Initiativen eingehen, die aktuell pilotiert werden. Im Anschluss möchte ich die Frage in den Raum geben, welche anderen Perspektiven auf die beschriebene Herausforderung bestehen und welche Lösungen darüberhinaus denkbar sind.

Openwashing ist ein wachsendes Problem für Nutzer und Entwicklerinnen Freier Software, für öffentliche Verwaltungen und das gesamte Freie-Software-Ökosystem. Immer wieder schmücken sich Unternehmen mit den Begriffen „frei" und "open" und versuchen zu verschleiern, dass sie proprietäre Software vertreiben. Die vermeintliche Kreativität der Openwasher ist groß. Sie schaden dem Ziel, mit Steuermitteln ausschließlich Freie Software für Verwaltungen zu beschaffen, wie es die Free Software Foundation Europe (FSFE) mit ihrer Initiaitve "Public Money? Public Code!" seit langem fordert. Und sie führen auch Verbraucher und andere Unternehmen hinters Licht. Die FSFE hat deswegen in einer Community-Umfrage Informationen über Openwashing gesammelt. Der Vortrag greift die Ergebnisse dieser Umfrage auf und gibt eine Übersicht über verbreitete Openwashing-Methoden und -Indikatoren. Er wirft ein Schlaglicht auf einige Openwashing-Beispiele und stellt Ideen zum Vorgehen gegen Openwashing vor.

Dabei nutzen wir eine „Schulstick“ genannte und auf dem bewährten Debian-Linux aufbauende Software-Sammlung, deren Entwicklung 2016 als „Uni-Stick“ an der TU Dresden begann und die mittlerweile eine umfassende Lern-, Spiel- und Arbeitsplattform für Schülerinnen und Schüler von der Grundschule bis zum Abschluss bietet. Eine große Vielfalt aktueller Freier Software inklusive Betriebssystem wird so auf handelsübliche USB-Sticks (min. 16GiB, Kosten etwa 6€) kopiert, dass jeder Desktop- oder Notebook-Rechner (x86 mit mehr als 2GiB Arbeitsspeicher) damit innerhalb von zwei Minuten gestartet und benutzt werden kann, ohne dass die bereits auf dem Computer installierte Software verändert wird. Dies ermöglicht z.B. die Nutzung auf Hardware der Eltern oder Geschwister, ohne dass diese Angst haben müssen, dass etwas an ihrem System beschädigt werden kann. Die auf dem Schulstick enthaltenen Programme sind kindgerecht ausgewählt und vorkonfiguriert und stehen ohne Download, Installation und Registrierung sofort zur Verfügung. Auch eine stetig wachsende Anzahl an „Open Educational Resources“ (OER), d.h. frei verfügbaren Bildungsmaterialien, sind auf dem Stick zu finden. Somit erhalten die Schülerinnen und Schüler einen mächtigen digitalen Werkzeugkasten in Daumennagelgröße, mit dem sie ihr persönliches System auf jeder geeigneten Hardware in der Schule und zuhause starten können. Neben dem Schulstick und dem Unistick gibt es noch eine weitere Stick-Variante, die sich an „Maker“ richtet und eine erweiterte Softwareauswahl (u.a. für 3D-Druck) hat. Eine aktuelle Version des Schulsticks zum Download und weitere Informationen sind auf https://schulstick.org/ zu finden. Im Vortrag auf den datenspuren2024 zeigen wir diverse Anwendungen wie CircuitJS, FreeTube, YouTube, Ranger, GDU und viele mehr. Zusätzlich präsentieren wir die Customizations: - Im Firefox haben wir Usability-Hacks und Add-ons integriert, um ihn vorkonfiguriert ohne nervige Meldungen beim ersten Start zu nutzen – was eine knifflige Herausforderung darstellt! - Unser Terminal-Desktop ist mit einer umfangreichen tmux, Ranger, Vim und einer Git-Toolsuite sowie einer speziellen Konfiguration ausgestattet. - Wir bieten einen Theme-Umschalter für hell und dunkel sowie einen automatischen Nachtmodus mit einstellbarem Blaufilterübergang. - Außerdem haben wir dicke Scrollbalken implementiert und ein Easter Egg im Makerstick versteckt. Wir zeigen auch die Historie im Repository sowie die Contributors-Page auf GitHub. Darüber hinaus präsentieren wir die Stickvarianten und die durch Symlinks aktivierten Features. Ein weiterer Punkt sind die Bash-Buildskripte, die Verwendung von jq und die Feature-install-hooks; zukünftig planen wir eventuell den Einsatz von Python und mehr nativen Debian-Paketen. Abschließend geben wir einen Ausblick auf die Entwicklung einer OER-Portal-App (hier gibt es Fördermittel und Unterstützungsbedarf!) und eines ML-unterstützten GUI-Assistenten, sowie ein i18n-Bootmenü.

You are in cardiac arrest. Your heart has stopped beating, you have stopped breathing, and medically speaking you have died. Not a great start to your day! But worry not: someone has called 999. This talk is the story of that 999 call. This talk, presented by the CAD & Technical Lead at the London Ambulance Service, will describe everything that happens between dialling 999 and getting to hospital, and all of the technology involved in triaging the call, dispatching the ambulance, and helping patients over the phone before it arrives. This isn't a heartwarming human-interest story from the documentaries — this is the full ins and outs of all the systems, processes, and infrastructure that keeps people safe across a major city every day.

We'll also look at what happens when it all goes wrong, and how we respond to business continuity incidents — after all, we can't just shut up shop if the system goes down.

You are in cardiac arrest. Your heart has stopped beating, you have stopped breathing, and medically speaking you have died. Not a great start to your day! But worry not: someone has called 999. This talk is the story of that 999 call. This talk, presented by the CAD & Technical Lead at the London Ambulance Service, will describe everything that happens between dialling 999 and getting to hospital, and all of the technology involved in triaging the call, dispatching the ambulance, and helping patients over the phone before it arrives. This isn't a heartwarming human-interest story from the documentaries — this is the full ins and outs of all the systems, processes, and infrastructure that keeps people safe across a major city every day. We'll explore how we use open data to find exactly where you are, exactly how we decide who gets help quickest and who must wait, and how your phone can help save your life. We'll also look at what happens when it all goes wrong, and how we respond to business continuity incidents — after all, we can't just shut up shop if the system goes down.

For this project, we wanted to explore more the findings of previous research around the guilt mothers feel when feeding their babies, but in a more creative way. Coming at the project from 3 very different points of expertise, we worked with mums to design and make a touch interactive quilt. We asked mothers of young babies to describe their emotions around feeding, a topic often emotional and controversial, and send a voice clip along with a piece of their baby’s clothing which we stitched together to create a special interactive quilt. The quilt is embedded with electronic touch sensors which activate the clips when the metal buttons of the clothes are touched. By interacting with them you can hear the stories through headphones. All this results in a very intimate and emotional experience that provides a platform for visibility and understanding and we think is a great conversation starter to share stories and create community. The talk will include a timeline of how we created a digitally augmented quilt, and a few thoughts if you want to make one too. It will also include some of our own reflections when working on a project that brings up difficult emotions and sensitive topics. about this event: https://www.emfcamp.org/schedule/2024/34-mothers-g-q-uilt </description> <enclosure url="https://cdn.media.ccc.de/events/emf/2024/h264-hd/emf2024-34-eng-Mothers_G_q_uilt_An_exploration_of_mothers_experiences_through_an_interactive_quilt_hd.mp4" length="430964736" type="video/mp4"/> <pubDate>Fri, 31 May 2024 15:20:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/emf/2024/h264-hd/emf2024-34-eng-Mothers_G_q_uilt_An_exploration_of_mothers_experiences_through_an_interactive_quilt_hd.mp4?1725110533</guid> <dc:identifier>3957c32a-07d7-5d17-b419-53e41fb53676</dc:identifier> <dc:date>2024-05-31T15:20:00+02:00</dc:date> <itunes:author>Sophia Komninou</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>34, emf2024, talk, Stage B, 2024, Day 2</itunes:keywords> <itunes:summary>This is a talk about how we combined textiles, electronics and storytelling to provide a platform for people to share experiences.

But something was wrong - SSH was taking up too much CPU time in the background. This accidental observation led to the discovery of an audacious attempt to introduce a backdoor that would allow an attacker access to almost any system in the world running SSH, an attack made up of both technical and social components. This talk will describe the backdoor itself, the process that went into it being possible to inject in the first place, and how this was exacerbated by a series of entirely reasonable decisions on the part of Linux distributions. It's a story of social engineering, novel obfuscation mechanisms, and a long con over several years. We'll delve into why distributions patch upstream code, why dependency chains are complicated, and how it's even possible for a compression library to break all the SSH security mechanisms that are intended to prevent this sort of thing from happening in the first place. about this event: https://www.emfcamp.org/schedule/2024/409-the-xz-backdoor-what-why-and-how </description> <enclosure url="https://cdn.media.ccc.de/events/emf/2024/h264-hd/emf2024-409-eng-The_XZ_backdoor_-_what_why_and_how_hd.mp4" length="445644800" type="video/mp4"/> <pubDate>Fri, 31 May 2024 17:40:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/emf/2024/h264-hd/emf2024-409-eng-The_XZ_backdoor_-_what_why_and_how_hd.mp4?1725116730</guid> <dc:identifier>4ba3664b-209b-58b7-b30d-8645f837b057</dc:identifier> <dc:date>2024-05-31T17:40:00+02:00</dc:date> <itunes:author>Matthew Garrett</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>409, emf2024, talk, Stage A, 2024, Day 2</itunes:keywords> <itunes:summary>Earlier this year, a developer was trying to benchmark a database.

An industrial coffee machine with a touchscreen and cocoa toppings? No idea where we would find enough room for it or if it would actually be used, but of course we'd be interested! After a few months of collecting (additional) dust and annoying a few members, we started the quest to get this machine back to work and to explore the (questionable) world of industrial coffee vending legacy, from hardware, over electronics to software architecture. This is a talk about how we repaired the machine, how these machines usually work, a dive into legacy software and electronics setups, and why those coffee vending machines taste like they do. Last but not least, we will discuss how we started to reverse engineer the internal system communication and if we would award a hackvalue of over 9000 for this type of machines.

(emf2024)</title> <link>https://media.ccc.de/v/emf2024-161-gas-boilers-suck-hack-yours-today-save-money-save-the-planet</link> <description>Gas boilers, almost all homes in the UK have them, but they are dreadful! +90% of the ones I've seen are badly spec'ed and horribly configured, so they burn way too much gas. Then Martin Lewis keeps telling us to "lower the flow temperature" but it's never really explained how to, or what this does to save gas (and money). Well have I got a Slide Deck for you!! As with any serious problem, it needs hard data. So I wired my Raspberry Pi home server to my central heating controls, wrote a bunch of code, and spent last winter collecting data from my boiler, a dozen temperature sensors, some humidity sensors and the Octopus Energy API. I have pretty graphs to show what happens all around my home, how altering the flow temperature works, how altering set points work, why my house was too cold, then too hot, and used way too much gas. I'll explain the (simple) physics and how to tweak your system for best performance too. But ultimately, we all have to stop burning gas and move to heat pumps, a solution not understood by many and requiring something of a mind shift from the way gas central heating has always worked. I'll explain how heat pumps work and what you can do to prepare for their arrival in your home. The future is bright, and it's heading rapidly in this direction. about this event: https://www.emfcamp.org/schedule/2024/161-gas-boilers-suck-hack-yours-today-save-money-save-the-planet </description> <enclosure url="https://cdn.media.ccc.de/events/emf/2024/h264-hd/emf2024-161-eng-Gas_boilers_suck_Hack_yours_today_save_money_save_the_planet_hd.mp4" length="408944640" type="video/mp4"/> <pubDate>Sat, 01 Jun 2024 12:20:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/emf/2024/h264-hd/emf2024-161-eng-Gas_boilers_suck_Hack_yours_today_save_money_save_the_planet_hd.mp4?1725121178</guid> <dc:identifier>d3df2a08-5f78-5b6f-8c05-a717da510047</dc:identifier> <dc:date>2024-06-01T12:20:00+02:00</dc:date> <itunes:author>Lee V</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>161, emf2024, talk, Stage A, 2024, Day 3</itunes:keywords> <itunes:summary>Gas boilers, almost all homes in the UK have them, but they are dreadful! +90% of the ones I've seen are badly spec'ed and horribly configured, so they burn way too much gas.

Mobile phones can sort-of do this, but they manage by listening to the cell towers, so this won't work everywhere. "Radio controlled" clocks just listen to a low frequency broadcast, there's a few different transmissions across the world but they're incompatible and know nothing of time zones. Desktop computers can use the internet for time, but you still have to tell it what zone you're in. Really, it should be possible to build a clock with nothing more than a GPS receiver, which figures out the time on its own, with no need for internet or cellular connection. It turns out that doing this requires an on-board world atlas, a spherical coordinate point-in-polygon algorithm, and a complete database of offsets and daylight savings rules. I finally created a clock that automatically corrects itself as you carry it across country and timezone borders. The journey to this point was so ridiculously tedious that it borders on the absurd.

(emf2024)</title> <link>https://media.ccc.de/v/emf2024-120-eversong-singing-voice-transfer</link> <description>Emily Peasgood and Mark Hanslip will present a talk on creating EverSong, followed by an invitation to try their vocal transfer models in real-time. EverSong is a sound installation where you can hear the lifespan of a person in a song, from 5-years-old at the start to 95-years-old at the end. It explores the fragility of life, its circularity, invites people to celebrate the moment we are in right now and questions our legacy as humans moving into an increasingly digital age. Since January 2024, Peasgood & Hanslip have worked with DDSP-SVC, a newly-developed process which builds on Google Magenta’s DDSP by combining it with a diffusion-based vocoder. They recorded vocal datasets with people aged 5-95 and trained models which can be mapped onto Emily’s voice enabling her to sound younger and older than she is. This technology is starting to be adopted by contemporary pop musicians, high-profile examples being web services such as Grimes’ Elf and Holly Herndon’s Holly+. EverSong represents a new application of this technology by making it possible to hear a voice age in real time. It will be experienced in tunnels and pathways, installed sustainably in nature, touring before finding a permanent home in an ancient site. about this event: https://www.emfcamp.org/schedule/2024/120-eversong-singing-voice-transfer </description> <enclosure url="https://cdn.media.ccc.de/events/emf/2024/h264-hd/emf2024-120-eng-EverSong_-_singing_voice_transfer_with_Google_Magentas_DDSP_diffusion-based_vocoder_hd.mp4" length="351272960" type="video/mp4"/> <pubDate>Sat, 01 Jun 2024 14:20:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/emf/2024/h264-hd/emf2024-120-eng-EverSong_-_singing_voice_transfer_with_Google_Magentas_DDSP_diffusion-based_vocoder_hd.mp4?1725122282</guid> <dc:identifier>23683f6c-0f82-5aab-b214-307f1806c901</dc:identifier> <dc:date>2024-06-01T14:20:00+02:00</dc:date> <itunes:author>Emily Peasgood & Mark Hanslip</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>120, emf2024, talk, Stage C, 2024, Day 3</itunes:keywords> <itunes:summary>Emily Peasgood and Mark Hanslip will present a talk on creating EverSong, followed by an invitation to try their vocal transfer models in real-time.

Beyond this, it's surprisingly rare to find good information beyond the basic physics and the marketing promise of unlimited, clean energy. As an engineer working in the fusion technology sector, I give a primer on how fusion power works, why its benefits are so incredibly tantalising yet hard to achieve, what the latest exciting developments are, and how the UK is a surprising trailblazer. I outline some of the cutting-edge technologies involved in developing fusion power, including superconducting magnets, plasma control using deep learning methods, and hypersonic fuel injection. The audience is also given facts and figures to get a flavour of the unimaginable scale of what is being done: materials at nearly 0K adjacent to plasmas hotter than the cores of stars, gigawatts of power from teaspoons of fuel, magnetic fields multiple times more powerful than MRI machines, and neutron fluxes strong enough to transmute matter in bulk. Coming away from this presentation, the audience will have learned about the fundamentals of nuclear fusion and appreciate the key issues enough to put the marketing and news reports into context. They might even be excited and enthused about what's to come in this quickly growing technology space. about this event: https://www.emfcamp.org/schedule/2024/471-unlimited-power </description> <enclosure url="https://cdn.media.ccc.de/events/emf/2024/h264-hd/emf2024-471-eng-Unlimited_Power_An_Engineers_Low-Down_on_Nuclear_Fusion_Technology_hd.mp4" length="405798912" type="video/mp4"/> <pubDate>Sun, 02 Jun 2024 17:10:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/emf/2024/h264-hd/emf2024-471-eng-Unlimited_Power_An_Engineers_Low-Down_on_Nuclear_Fusion_Technology_hd.mp4?1725133898</guid> <dc:identifier>0c31ac3d-9261-579d-bfb5-78961a8c2539</dc:identifier> <dc:date>2024-06-02T17:10:00+02:00</dc:date> <itunes:author>James Pope</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>471, emf2024, talk, Stage C, 2024, Day 4</itunes:keywords> <itunes:summary>Most technical people hear about fusion power in the news or see it in games and movies, and are familiar with the joke that it's always 20 years away.

Coming away from this presentation, the audience will have learned about the fundamentals of nuclear fusion and appreciate the key issues enough to put the marketing and news reports into context. They might even be excited and enthused about what's to come in this quickly growing technology space. about this event: https://www.emfcamp.org/schedule/2024/471-unlimited-power </itunes:summary> <itunes:duration>00:30:17</itunes:duration> </item> <item> <title>Influence policing: a view from the cockpit of UK law enforcement’s domestic digital influence campaigns (emf2024)</title> <link>https://media.ccc.de/v/emf2024-237-influence-policing</link> <description>Critical research on digital influence and micro targeting has generally focused on privacy violations by commercial marketers and Cambridge Analytica-style political manipulation. But increasingly, the UK government, police, and security services are using these tools for public policy. The targeted advertising and influence platforms give public sector actors complex tools with which to target behaviour change communications - allowing them to tailor nudge messages based on online behaviour, interests, and fine-detail location. This is allowing the police to use targeted behaviour change advertising to attempt to prevent crime before it happens - but poses serious questions for accountability, ethics, and privacy. Drawing on a dataset of more than 12,000 government adverts from the Meta Ad Library and in-depth interviews with law enforcement, we map the landscape of what we call 'influence policing' in the UK, and discuss the ethical and democratic implications of this new mode of policing. about this event: https://www.emfcamp.org/schedule/2024/237-influence-policing </description> <enclosure url="https://cdn.media.ccc.de/events/emf/2024/h264-hd/emf2024-237-eng-Influence_policing_a_view_from_the_cockpit_of_UK_law_enforcements_domestic_digital_influence_campaigns_hd.mp4" length="624951296" type="video/mp4"/> <pubDate>Sat, 01 Jun 2024 14:30:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/emf/2024/h264-hd/emf2024-237-eng-Influence_policing_a_view_from_the_cockpit_of_UK_law_enforcements_domestic_digital_influence_campaigns_hd.mp4?1725123635</guid> <dc:identifier>2cb90397-ae27-5e21-a042-ed9324f6aa30</dc:identifier> <dc:date>2024-06-01T14:30:00+02:00</dc:date> <itunes:author>Ben Collier</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>237, emf2024, talk, Stage B, 2024, Day 3</itunes:keywords> <itunes:summary>Critical research on digital influence and micro targeting has generally focused on privacy violations by commercial marketers and Cambridge Analytica-style political manipulation.

Our hackspace recently got a donation of ~800 LED matrix panels (squares with lots of tiny LEDs on them), with little in the way of documentation. I'll explain how they work, how we got them to light up and display things, and how to make it fast enough to display 30fps video -- all with commodity parts that cost less than 20 pounds. We'll explore the weird and wonderful world of poorly translated datasheets and control software, marvel at the library of weird glitched-out images I ended up with on the road to success, and dive into the strange but extremely useful Programmable I/O block of the RP2040 microcontroller. If the stars align, you'll be able to see everything working on a real demonstration panel, too!

Conventional hardware architectures and the C/C++ codebase are chronically prone to exploitable errors - a 75-year-old problem at the heart of computing. This talk will introduce CHERI, showing how (finally?!) we can do better. The CHERI research project has developed a new architecture+software approach, using unforgeable hardware capabilities to implement pointers. Morello is an Arm experimental platform for evaluation of CHERI to explore its potential for mass-market adoption, part-funded by the UKRI Digital Security by Design programme, and other groups are developing CHERI-enabled RISC-V processors, including Microsoft, Google, lowRISC, SCI Semiconductor, Codasip, and RISC-V International. This talk will introduce the problem, and CHERI and Morello, for a broad audience: the hardware extensions, their potential for fine-grained memory safety and software compartmentalisation, the CHERI software stack, and machine-checked mathematical proof that the architecture design provides the intended security. CHERI complements alternative high-level-language approaches, that would need code to be rewritten from scratch, and we'll talk about the often-low cost of porting code to CHERI. I'll demo how CHERI prevents exploitable memory safety errors on a Morello box, running Arm CHERI hardware and a complete CHERI software stack. This is joint work by the CHERI and Morello teams at the University of Cambridge, Arm, SRI International, and the University of Edinburgh. about this event: https://www.emfcamp.org/schedule/2024/87-cheri-and-arm-morello </description> <enclosure url="https://cdn.media.ccc.de/events/emf/2024/h264-hd/emf2024-87-eng-CHERI_and_Arm_Morello_mitigating_the_terrible_legacy_of_memory-safety_security_issues_in_practice_at_scale_hd.mp4" length="342884352" type="video/mp4"/> <pubDate>Fri, 31 May 2024 18:30:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/emf/2024/h264-hd/emf2024-87-eng-CHERI_and_Arm_Morello_mitigating_the_terrible_legacy_of_memory-safety_security_issues_in_practice_at_scale_hd.mp4?1725111960</guid> <dc:identifier>b3ecfa2a-5f57-53ff-8442-ab1aea12c561</dc:identifier> <dc:date>2024-05-31T18:30:00+02:00</dc:date> <itunes:author>Peter Sewell</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>87, emf2024, talk, Stage C, 2024, Day 2</itunes:keywords> <itunes:summary>Computing is riddled with security vulnerabilities, many of which arise from memory safety issues.

And if you didn't, this talk will explain why you should care about a now 40-year-old game. It was years ahead of its time, with 3D graphics, a procedurally generated open world, and a whole novel's worth of lore - all running on an 8-bit home microcomputer in 1984, when most games were little more advanced than Pac-Man or Space Invaders. Over the last few years, I've been picking apart the original Elite game engine to understand how it worked, and also to experiment with extending it. In this talk, I'll examine some of the methods that the game used - how it used the graphics hardware, how the game state is represented in memory, how the ship models were designed, how the AI worked, and how galaxies and planets were generated. I'll also explain some quirks of the game... including the real reason that docking was so hard. I'll demonstrate some new tools I've developed, which access the game state in real time, letting you experience the original game in new ways - including an OpenGL frontend with VR support, and an attempt to recreate an arcade-style version of the game, with an old-school vector display. Finally, if all goes to plan, I will attempt to demonstrate something that was an impossible dream for 40 years: multiplayer Elite on the original BBC Micro version. about this event: https://www.emfcamp.org/schedule/2024/113-exploring-and-extending-the-elite-game-engine </description> <enclosure url="https://cdn.media.ccc.de/events/emf/2024/h264-hd/emf2024-113-eng-Exploring_and_extending_the_Elite_game_engine_for_the_BBC_Micro_hd.mp4" length="844103680" type="video/mp4"/> <pubDate>Sat, 01 Jun 2024 13:40:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/emf/2024/h264-hd/emf2024-113-eng-Exploring_and_extending_the_Elite_game_engine_for_the_BBC_Micro_hd.mp4?1725123250</guid> <dc:identifier>fec079b8-9645-501f-bb93-2757dc89bbc0</dc:identifier> <dc:date>2024-06-01T13:40:00+02:00</dc:date> <itunes:author>Martin Ling</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>113, emf2024, talk, Stage B, 2024, Day 3</itunes:keywords> <itunes:summary>If you are a British nerd of a certain age, you almost certainly played Elite on the BBC Micro.

When used with WireGuard, Rosenpass functions as a ready-to-use virtual private network with full security against quantum attackers.The development of a technology like Rosenpass is complex and requires a good footing in cryptographic research, software engineering, industry practices, and science communication. Bringing together these diverse threads of activity is an ongoing challenge. Individual work is not enough, it takes a group; an organization. We are the group that tries to tackle these challenges for Rosenpass.In this talk, we will focus on Rosenpass as a protocol and explain the principles used and challenges encountered when designing such a protocol. Equipped with ample time and many scientific illustrations, we hope to give insight to an audience with many different levels of knowledge about cryptographic subjects.This is not a lecture for experts. This is supposed to be entertainment for the technologically inclined.In the talk we are going to explain what key encapsulation methods are, how they are different from "non-interactive key exchanges" – often just called "Diffie-Hellman" operations. We will demonstrate how key encapsulation methods can be used to build a secure cryptographic key exchange protocol and how the X-Wing fighter can be used to provide cryptographic redundancy.Finally, we will turn our attention to attacks we found against WireGuard, show off a protocol level denial-of-service attack against WireGuard and explain how we solved that attack in Rosenpass. about this event: https://sessions.hack-mas.at/event/jzGHNoejBMT5hNBbC/how-to-build-post-quantum-cryptographic-protocols-and-why-wall-clocks-are-not-to </description> <enclosure url="https://cdn.media.ccc.de/events/hackmas/2024/h264-hd/hackmas2024-1927564986-eng-How_to_build_post-quantum_cryptographic_protocols_and_why_wall_clocks_are_not_to_be_trusted_hd.mp4" length="1192230912" type="video/mp4"/> <pubDate>Fri, 30 Aug 2024 22:00:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/hackmas/2024/h264-hd/hackmas2024-1927564986-eng-How_to_build_post-quantum_cryptographic_protocols_and_why_wall_clocks_are_not_to_be_trusted_hd.mp4?1725100249</guid> <dc:identifier>66ff7eec-3110-5cee-8d8a-f9e6712dd1c5</dc:identifier> <dc:date>2024-08-30T22:00:00+02:00</dc:date> <itunes:author>mapc</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>1927564986, hackmas2024, Lise Meitner (1.OG), 2024, Day 3</itunes:keywords> <itunes:summary>Rosenpass is a post-quantum secure cryptographic protocol, an implementation of that protocol in the Rust programming language, and a governance organization stewarding development of both protocol and implementation.

After a chance introduction to an Austrailian biology student in 2022, Chris and Jay have spent the last few years researching the mechanics of hair growth, the structures of Amino Acids and Keratins and the composition of different parts of human hair. They used this research to develop a suite of software tools that use these bio-mechanics as a structure for creating music.

In 2022 we convened a group of artists, technologists, designers and activists to start the project. As result of the connections made, we have identified themes and ideas that we will present in this talk. The five themes are Community, Sustainability, Software, Hardware and Creative.

The vast majority of our modern foods originate overseas, introduced to Britain by colonialism and Victorian exploration, and the global human diet now contains less than 100 plants, with limited biodiversity. Starting from the BSBI's database of native and naturalised plants, over the course of 3+ years I painstakingly reseached each entry for historic, archaeological, or ethnographically documented food uses. This body of ancestral knowledge could help provide local food resilience, reduce the impact of the plants we eat, and better protect food supplies from climate change, pollinator loss and disease. The research is still in its raw form as a giant spreadsheet, so the first part of the talk will focus on the process of research and identification, and some of the trickier questions such as the difference between a food and a medicine, what level of toxicity is tolerable, and how to really define a native plant. The second part will focus on some highlights of the results, including obscure disused vegetables, native things you can still forage, lost recipes for brewed alcohols and psychoactives, vegetables we've bioengineered for edibility, some exciting natural poisions, and addressing whether or not lettuce really exists. about this event: https://www.emfcamp.org/schedule/2024/461-the-edible-native-plant-project </description> <enclosure url="https://cdn.media.ccc.de/events/emf/2024/h264-hd/emf2024-461-eng-The_Edible_Native_Plant_Project_or_the_Fine_Line_Between_Food_and_Poison_hd.mp4" length="584056832" type="video/mp4"/> <pubDate>Sat, 01 Jun 2024 18:10:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/emf/2024/h264-hd/emf2024-461-eng-The_Edible_Native_Plant_Project_or_the_Fine_Line_Between_Food_and_Poison_hd.mp4?1725124532</guid> <dc:identifier>8cff100d-4222-5025-bfc0-e5b59f7cc85e</dc:identifier> <dc:date>2024-06-01T18:10:00+02:00</dc:date> <itunes:author>Katherine McLean Forster</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>461, emf2024, talk, Stage A, 2024, Day 3</itunes:keywords> <itunes:summary>A research project that started with the question, 'what was the average person in Britain eating 500 years ago?', and resulted in a rich knowledge base of over 1200 native and naturalised plants with food uses.

Inspired by the film "Don't Look Up", where Benn produced the impact campaign, we will explore this dynamic together. When the ethics are no longer focused on being accurate, but rather being first,and being attention grabbing, it becomes difficult for people to discern what is and is not an important story. So we wonder how some of the most important stories either fall through the ether entirely, or are seen and dismissed by the apparatus of the 24 hour news cycle and 3 second refresh feeds. That's what films like Don't Look Up tackle so well. Benn is a SXSW Grand Jury Prize & UNICEF Prize winning, Oscar Shortlisted, Webby nominated producer. He has been a social impact advisor and producer working across film, games and events, with a mission to bridge gaps between story and policy, and ultimately champion vast perspectives to aid social movement. He is the Head of Partnerships for Neon Picturehouse, and Executive Producer & Vice-Chairman of HF Productions. He serves as an Advisor of Think Film, Global Environment Media, Screen South, SIE Society, and Treun House Atelier.

But while it sounds simple, many things can go wrong. What ends up in the cup can too easily end up bitter, sour, watery, chalky, harsh, or flat. So how can you be an espresso alchemist, and convert your bitter shots into gold? In this talk, I'll cover the anatomy of what goes on during coffee extraction, and the problems that can lead to bad flavoured coffee. I'll also give a whirlwind tour of the different coffee machines, equipment, and hacks that are designed to make better espresso - both the high-value gadets and the duds. You'll learn how to 'dial in' a shot to prevent it being too sour or bitter, and what steps you can take to maximise deliciousness! about this event: https://www.emfcamp.org/schedule/2024/133-the-coffee-fix-why-its-so-hard-to-pull-a-great-espresso </description> <enclosure url="https://cdn.media.ccc.de/events/emf/2024/h264-hd/emf2024-133-eng-The_coffee_fix_Why_its_so_hard_to_pull_a_great_espresso_and_how_to_improve_your_shots_hd.mp4" length="439353344" type="video/mp4"/> <pubDate>Fri, 31 May 2024 16:30:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/emf/2024/h264-hd/emf2024-133-eng-The_coffee_fix_Why_its_so_hard_to_pull_a_great_espresso_and_how_to_improve_your_shots_hd.mp4?1725115885</guid> <dc:identifier>13bc043a-1322-5a35-8735-532e53e79bd4</dc:identifier> <dc:date>2024-05-31T16:30:00+02:00</dc:date> <itunes:author>Damian Bramanis</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>133, emf2024, talk, Stage B, 2024, Day 2</itunes:keywords> <itunes:summary>Pulling a shot of espresso sounds so simple - just pump some water through a bed of coffee grounds. But while it sounds simple, many things can go wrong. What ends up in the cup can too easily end up bitter, sour, watery, chalky, harsh, or flat. So how can you be an espresso alchemist, and convert your bitter shots into gold? In this talk, I'll cover the anatomy of what goes on during coffee extraction, and the problems that can lead to bad flavoured coffee.

Firstly, I will introduce MATLAB and Simulink, the industry standard tools used by engineers worldwide to program everything from cars engines to smartphone cameras to spacecraft navigation systems. Next I will give some examples of how these tools can greatly speed up the development of software for a wide range of low-cost hardware devices. Examples include, getting started with Computer Vision on a Raspberry Pi in only 3 lines of code; Programming an Arduino without learning C++ and modifying your code at runtime; Graphically designing a complex control system for a LEGO Mindstorms robot. about this event: https://c3voc.de </description> <enclosure url="https://cdn.media.ccc.de/events/emf/2014/h264-sd/emf2014-260-eng-Robotics_and_Computer_Vision_with_MATLAB_and_Simulink_sd.mp4" length="97517568" type="video/mp4"/> <pubDate>Sun, 31 Aug 2014 14:15:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/emf/2014/h264-sd/emf2014-260-eng-Robotics_and_Computer_Vision_with_MATLAB_and_Simulink_sd.mp4?1724728857</guid> <dc:identifier>0304eb6d-f091-5562-a149-707e88148847</dc:identifier> <dc:date>2014-08-31T14:15:00+02:00</dc:date> <itunes:author>Owen McAree</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>emf2014, 260, 2014</itunes:keywords> <itunes:summary> In this talk I will discuss how to dramatically improve the speed and quality of your robotics and computer vision projects using MATLAB and Simulink to program your Arduino, Raspberry Pi and LEGO Mindstorms.

Das schlanke Protokoll ermöglicht einen schnellen und ressourcenschonenden Datenverkehr zwischen den Netzwerkteilnehmern. Gerade diese Eigenschaften macht diese Technologie für batteriebetriebene Geräte interessant. Das Vernetzen von Geräten untereinander ist heute quasi Standard. In den allermeisten Fällen wird dabei TCP als Netzwerkprotokoll verwendet. Um aber z.B. via TCP eine Verbindung aufbauen und Daten austauschen zu können, sind eine Reihe von Schritten notwendig, welche, je nach Gegebenheiten, lange dauern und unter Umständen auch rechenintensiv sind. Erfolgt dann noch die Übertragung der Daten kabellos, merkt man schnell, wie stromhungrig Funktechnik sein kann. Diese Dinge erschweren die Entwicklung batteriebetriebener WLAN-Geräte erheblich.

Das schlanke Protokoll ermöglicht einen schnellen und ressourcenschonenden Datenverkehr zwischen den Netzwerkteilnehmern. Gerade diese Eigenschaften macht diese Technologie für batteriebetriebene Geräte interessant. Das Vernetzen von Geräten untereinander ist heute quasi Standard. In den allermeisten Fällen wird dabei TCP als Netzwerkprotokoll verwendet. Um aber z.B. via TCP eine Verbindung aufbauen und Daten austauschen zu können, sind eine Reihe von Schritten notwendig, welche, je nach Gegebenheiten, lange dauern und unter Umständen auch rechenintensiv sind. Erfolgt dann noch die Übertragung der Daten kabellos, merkt man schnell, wie stromhungrig Funktechnik sein kann. Diese Dinge erschweren die Entwicklung batteriebetriebener WLAN-Geräte erheblich. Im Rahmen dieses Vortrages wird erklärt, warum dies so ist und ESP-NOW wird, als alternatives Netzwerkprotokoll, dem gegenübergestellt. Schnell wird klar werden, warum ESP-NOW eine echte Alternative für den kabellosen Datenaustausch batteriebetriebener Geräte ist.

However, most of the used signing solutions either do not rely on hardware backed private key material or are run in untrusted environments. This presentation will provide a general overview of the [Signstar](https://gitlab.archlinux.org/archlinux/signstar/) project, which is currently under development by Arch Linux to provide a generic signing solution based on a Hardware Security Module (HSM). To improve build automation and general supply chain security for Arch Linux, some of its developers have started to conceptualize and work on a generic, central signing solution: [Signstar](https://gitlab.archlinux.org/archlinux/signstar/). In this context, related work has been evaluated for adoption, but it soon became clear, that to meet the distribution's requirements a custom solution would be implemented. For transparency and auditability reasons Nitrokey's NetHSM has been chosen as Hardware Security Module (HSM). Developers are actively working on a high-level Rust library and CLI to interface with the device over network. In this presentation I will introduce the viewer to some of Arch Linux's relevant history and requirements, the evaluated architecture and setup. Together we will have a look at Signstar's threat model, its design for minimizing credentials exposure of the HSM, as well as its integration with the OpenPGP ecosystem. Additionally, we will explore avenues for future work on other generic cryptographic operations in the context of X.509, SSH and Secure Boot. about this event: https://programm.froscon.org/2024/events/3139.html </description> <enclosure url="https://cdn.media.ccc.de/events/froscon/2024/h264-hd/froscon2024-3139-eng-Boring_infrastructure_Building_a_secure_signing_environment_hd.mp4" length="330301440" type="video/mp4"/> <pubDate>Sun, 18 Aug 2024 15:15:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/froscon/2024/h264-hd/froscon2024-3139-eng-Boring_infrastructure_Building_a_secure_signing_environment_hd.mp4?1723998206</guid> <dc:identifier>9f105816-8870-4cf2-b469-8d807d0e9021</dc:identifier> <dc:date>2024-08-18T15:15:00+02:00</dc:date> <itunes:author>dvzrv</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>froscon2024, 3139, 2024, In Rust we trust - Memory safe languages</itunes:keywords> <itunes:summary>Many Linux distributions rely on cryptographic signatures for their packages and release artifacts.

The past has shown that vulnerabilities in closed-source components may be exploited by attackers to undermine the security of a system. Attackers invest a considerable amount of effort and expertise into reverse-engineering these components to uncover complex vulnerabilities. Manufacturers that rely on closed source components oftentimes have neither the resources not the expertise to perform the same level of auditing. This imbalance leads to security issues in the final product that may directly impact its users. The cwe_checker is an open-source research prototype that performs static analysis of binary code to find potential vulnerabilities. It currently supports the analysis of Linux user space programs and kernel modules as well as bare-metal firmwares. Our goal is to reduce the time and expertise needed by vendors to thoroughly audit their closed-source dependencies. The talk will start with a short introduction to the general problem area, as outlined in the abstract, and proceed by introducing the goals behind the cwe_checker. It continues with a presentation of the idea, requirements, and high-level architecture of the cwe_checker. In its main part, the talk will walk through the development of a simple data-flow analysis that detects instances of CWE252 (Unchecked Return Value). It will cover both, conceptual aspects behind the static analysis algorithm and the concrete code that implements it using the internal cwe_checker APIs. Finally, the algorithm will be used to find unchecked return values of `copy_from_user`, a programming error that is almost certainly exploitable, in non-upstream Linux device drivers taken from embedded device firmware images. To conclude the talk, an overview of other available analyses as well as possible directions for future research will be given. Students interested in Rust and program analysis are invited to contact us for thesis projects and internship opportunities. External contributions to the cwe_checker have unfortunately been uncommon due to the steep learning curve and absence of walkthrough-style documentation. (There is detailed rustdoc documentation of all APIs.)

Join us in taking a look at how the Sovereign Tech Fund, a state-funded organization in Germany, has been developing ways to strengthen and support the free and open source ecosystem in the public interest. This ecosystem underpins the digital infrastructure, in particular the software components and tools, on which governments, private companies, and individuals rely. But what does it mean to strengthen this ecosystem? In this session we’ll look at the different ways STF is putting public money to work for this mission. Some of the issues STF is working on include: a) Limited funding for long-term maintenance and security work b) Fragmented career and employment prospects for project maintainers c) Growing the pool of open source maintainers and contributors We’ll include lessons from the first two years of our existence, some insights from our survey of open source maintainers, as well some ideas on how all the different parts in the FOSS landscape can work together for a more resilient and fair system.

(froscon2024)</title> <link>https://media.ccc.de/v/froscon2024-3151-sovereign_cloud_stack_-_one_platform_standardized_built_and_operated_by_many</link> <description>Eine Projektvorstellung des Sovereign Cloud Stack mit einem Schwerpunkt auf der Zusammenarbeit mit der öffentlichen Hand, einer Menge Lessons-Learned aus den letzten drei Jahren und einem Ausblick auf die spannende Zeit, die jetzt nach der Förderung ansteht. Das Sovereign Cloud Stack-Projekt startete vor drei Jahren mit dem Ziel, Cloud-Infrastrukturen und -Dienste zu standardisieren und die Art und Weise, wie Cloud-Anwendungen betrieben werden. "Eine Plattform standardisiert, gebaut und betrieben von vielen" stellt das Leitmotiv des Projekts dar. Die drei Säulen des SCS Projekts sind zertifizierte Standards, eine modulare Open-Source-Referenzimplementierung und offene Betriebsmodelle. Insbesondere vor dem Hintergrund der zertifizierbaren Standards ist eine Kooperation mit der öffentlichen Hand von Bedeutung und notwendig. Das SCS-Projekt wird seit Sommer 2021 vom Bundesministerium für Wirtschaft und Klimaschutz gefördert. Die Förderung endet diesen September, und wir möchten einen Überblick geben, was wir bisher erreicht haben, welchen Einfluss wir auf unsere umliegenden Ökosysteme hatten und erläutern, warum dieses Projekt fortgesetzt werden muss und wie die Hebelwirkung in Zukunft aussehen wird. SCS wird in der 'Deutschen Verwaltungscloud Strategie' (DVC) erwähnt und arbeitet auf politischer Ebene daran, Open Source und offene Standards auf den Tisch zu bringen. An verschiedenen Stellen gibt es in der öffentlichen Hand Bestrebungen auf Open-Source-Technologie zu setzen: Mit der Referenzimplementierung des SCS wird für den Betrieb von Cloud-Infrastruktur ein schlüsselfertiger Open-Source-Stack, finanziert aus öffentlichen Geldern, zur Verfügung gestellt. Public Money, Public Code at its best. Insbesondere wird der Vortrag auf die Initiativen und Diskussionen in den Upstream-Communitys (wie OpenStack, Cluster-API, OSISM, …) eingehen, die wir initiiert und durchgeführt haben, sowie auf die Änderungen und Ergänzungen, die wir initiiert haben, eingehen.

Das Sovereign Cloud Stack-Projekt startete vor drei Jahren mit dem Ziel, Cloud-Infrastrukturen und -Dienste zu standardisieren und die Art und Weise, wie Cloud-Anwendungen betrieben werden. "Eine Plattform standardisiert, gebaut und betrieben von vielen" stellt das Leitmotiv des Projekts dar. Die drei Säulen des SCS Projekts sind zertifizierte Standards, eine modulare Open-Source-Referenzimplementierung und offene Betriebsmodelle. Insbesondere vor dem Hintergrund der zertifizierbaren Standards ist eine Kooperation mit der öffentlichen Hand von Bedeutung und notwendig. Das SCS-Projekt wird seit Sommer 2021 vom Bundesministerium für Wirtschaft und Klimaschutz gefördert. Die Förderung endet diesen September, und wir möchten einen Überblick geben, was wir bisher erreicht haben, welchen Einfluss wir auf unsere umliegenden Ökosysteme hatten und erläutern, warum dieses Projekt fortgesetzt werden muss und wie die Hebelwirkung in Zukunft aussehen wird. SCS wird in der 'Deutschen Verwaltungscloud Strategie' (DVC) erwähnt und arbeitet auf politischer Ebene daran, Open Source und offene Standards auf den Tisch zu bringen. An verschiedenen Stellen gibt es in der öffentlichen Hand Bestrebungen auf Open-Source-Technologie zu setzen: Mit der Referenzimplementierung des SCS wird für den Betrieb von Cloud-Infrastruktur ein schlüsselfertiger Open-Source-Stack, finanziert aus öffentlichen Geldern, zur Verfügung gestellt. Public Money, Public Code at its best. Insbesondere wird der Vortrag auf die Initiativen und Diskussionen in den Upstream-Communitys (wie OpenStack, Cluster-API, OSISM, …) eingehen, die wir initiiert und durchgeführt haben, sowie auf die Änderungen und Ergänzungen, die wir initiiert haben, eingehen. Der Vortrag wird in ehrlicher Weise darlegen, wo und wie wir unsere Upstream-Bemühungen unter- oder überschätzt haben, was wir daraus gelernt haben und wie wir es in Zukunft angehen wollen. Außerdem wird der Vortrag auf die Erfolge und auch Schwierigkeiten bei der Adaption des Sovereign Cloud Stack seitens Cloudanbietern und Dienstleistern der öffentlichen Hand eingehen. Der Vortrag wird einen Rückblick bieten, um dem Publikum ein besseres Verständnis dafür zu vermitteln, was in Zukunft notwendig ist, um unsere Mission erfolgreich zu verwirklichen. about this event: https://programm.froscon.org/2024/events/3151.html </itunes:summary> <itunes:duration>01:00:39</itunes:duration> </item> <item> <title>alpaka.problem (jh24)</title> <link>https://media.ccc.de/v/jh24_rn-48-alpakaproblem</link> <description> about this event: https://c3voc.de </description> <enclosure url="https://cdn.media.ccc.de/events/jugendhackt/2024/h264-hd/jh24-rn-48-deu-alpakaproblem_hd.mp4" length="83886080" type="video/mp4"/> <pubDate>Sun, 21 Jul 2024 13:44:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/jugendhackt/2024/h264-hd/jh24-rn-48-deu-alpakaproblem_hd.mp4?1723895567</guid> <dc:identifier>f66e33c6-3227-4041-b5a9-69a20ff714d0</dc:identifier> <dc:date>2024-07-21T13:44:00+02:00</dc:date> <itunes:author>Jan, Karlsson, Tharo</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>jh24-rn, 48, 2024</itunes:keywords> <itunes:summary> about this event: https://c3voc.de </itunes:summary> <itunes:duration>00:08:42</itunes:duration> </item> <item> <title>High performance Serverless Java on AWS (froscon2024)</title> <link>https://media.ccc.de/v/froscon2024-3025-high_performance_serverless_java_on_aws</link> <description>Java is for many years one of the most popular programming languages, but it used to have hard times in the Serverless community.

Doch die meisten Plattformen setzen auf Tricks und suboptimale Algorithmen, um Nutzer zu binden/melken. Dieser Vortrag beleuchtet die Technik dahinter, die Erfolgschancen und Strategien, sowie Fragen wie: Was sind "red flags" und das Fünf-Faktoren-Modell (FFM)? Kann man mit kostenlosen Accounts erfolgreich sein (Frau ja, Mann nein)? Ist Online-Dating unromantisch? Für Technikinteressierte gibt es Tipps zu Automatisierung, ChatGPT und API-Nutzung. 39% der deutschen Internetnutzer haben oder hatten einen Account auf einer Online-Dating-Plattform. Mindestens 25% aller deutschen Paare haben sich auf einer solchen Plattform kennengelernt. Online-Plattformen verdienen das meiste Geld mit Nutzern, die erfolglos suchen. Entsprechend sind fast alle Algorithmen darauf ausgelegt, Nutzer so lange wie möglich zu binden bzw. zu melken. Dieser Vortrag gibt einen kurzen initialen Überblick über die existierenden Plattformen auf dem deutschen Markt und taucht danach direkt in die verwendete Technik und die wahrscheinlich eingesetzten Algorithmen ein. Was hat es mit dem Fünf-Faktoren-Modell (FFM) auf sich? Was sind "red flags" und "green flags"? Gibt es eine optimale Online-Dating-Plattform für mich? Wie kann man durch den Einsatz von Geld seine Chancen erhöhen? Kann man ohne bezahlte Accounts überhaupt Erfolg haben (Spoiler: auf den meisten Plattformen ist das fast unmöglich)? Wie hoch ist der Anteil der inaktiven Profile (Spoiler: gigantisch)? Was ist eine erfolgversprechende Taktik beim Online-Dating? Ist das alles nicht total unromantisch?

Phishing Mails sind immer noch einer der gefährlichsten Angriffsmethoden von Cyberkriminellen. Phishing Awareness Kampagnen sind deshalb in aller Munde. Organisationen möchten einen Überblick über den Ausbildungsstand Ihrer Benutzer bekommen und diese gleichzeitig langfristig und regelmäßig ausbilden. Professionelle Dienstleiter bieten Services für solche Aktionen an. Vorrausetzung für den effizienten und erfolgreichen Ablauf dieser Aktionen ist allerdings fast immer eine Schwächung der Firewall Einstellungen damit die Testmails die Postfächer der Endanwender erreichen.

Phishing Mails sind immer noch einer der gefährlichsten Angriffsmethoden von Cyberkriminellen. Phishing Awareness Kampagnen sind deshalb in aller Munde. Organisationen möchten einen Überblick über den Ausbildungsstand Ihrer Benutzer bekommen und diese gleichzeitig langfristig und regelmäßig ausbilden. Professionelle Dienstleiter bieten Services für solche Aktionen an. Vorrausetzung für den effizienten und erfolgreichen Ablauf dieser Aktionen ist allerdings fast immer eine Schwächung der Firewall Einstellungen damit die Testmails die Postfächer der Endanwender erreichen.

We want to provide an overview about existing containerization Solutions, their architecture, functionality, ecosystem and how they can be used in embedded Systems. Nowadays containers are so ommnipresent that a world without containerization seems unthinkable. They are often the Solution for portable and isolated environments for running applications.

This talk aims to provide an overview about existing containerization Solutions, their architecture, functionality, ecosystem and how they can be used in embedded Systems. Firstly, we quickly recap the fundamental technologies for containers including namespaces and cgroups. Additionally, we explore the broader context of containerization, contrasting it with alternative approaches such as virtual machines, traditional application deployment and UserModeLinux. Subsequently, we delve into the realm of container runtimes, focusing on popular implementations such as the Open Container Initiative (OCI) standards that include runc and crun, but also solutions like lxc will be covered. We also discuss older approaches such as lmctfy and CoreOS's rkt. Another important point is the ecosystem surrounding embedded containers, encompassing container registries for image distribution and the tooling required for building and managing containerized applications in embedded environments. Finally, a comparative analysis is presented that evaluaties embedded container runtimes based on criteria such as performance, security, ease of use and ecosystem support. about this event: https://programm.froscon.org/2024/events/3028.html </description> <enclosure url="https://cdn.media.ccc.de/events/froscon/2024/h264-hd/froscon2024-3028-deu-A_Comparative_Analysis_of_Embedded_Container_Runtimes_hd.mp4" length="443547648" type="video/mp4"/> <pubDate>Sun, 18 Aug 2024 14:00:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/froscon/2024/h264-hd/froscon2024-3028-deu-A_Comparative_Analysis_of_Embedded_Container_Runtimes_hd.mp4?1723994804</guid> <dc:identifier>532ee1fe-cdd8-4694-b427-ea9be837bf0a</dc:identifier> <dc:date>2024-08-18T14:00:00+02:00</dc:date> <itunes:author>Simone Weiß, Thomas Irgang</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>froscon2024, 3028, 2024, Development</itunes:keywords> <itunes:summary>Nowadays containers are so ommnipresent that a world without containerization seems unthinkable.

Allerdings tritt die schrittweise Evolution dieser Sprachmittel selber in Wechselwirkung mit der Entwicklung der Codebasis und erzeugt Wartungsprobleme. Dies wird beleuchtet am Beispiel von <i>Lambdas und Funktoren</i>, der Einführung von <i>RValue-Referenzen</i>, sowie der Entwicklung von <i>Generics und Concepts</i>. <i>Software lebt solange sie änderbar ist</i>. Für langlebige Software ist der Charakter der Programmiersprache bedeutsam. Der Charakter jeder Sprache, und die damit verbundenen Methoden entwickeln sich weiter. Daraus entsteht eine Wechselwirkung mit einer bestehenden Codebasis, die sich ebenfalls weiterentwickelt. Exemplarisch sei dies am Beispiel der Erfahrungen im <i>Projekt Lumiera</i> mit der <i>Sprache C++</i> aufgezeigt. In diesem OpenSource-Projekt wird Software für professionellen Film/Videoschnitt entwickelt. Die Entscheidung für eine Plattform ist im Kern eine Entscheidung für ein Ökosystem. Ein langlebiges Projekt muss auf Autonomie und Handlungsfähigkeit achten. Daher scheiden die meisten zunächst offensichtlichen und beliebten Plattformen aus. Für Lumiera hat man sich damals für C++ in einem Unix-Umfeld entschieden. Realistische andere Optionen wären noch gewesen: D, Java, C, Haskell. Einmal getroffen, ist eine solche Entscheidung mehr oder weniger endgültig. Denn jede der großen Programmiersprachen steht auch für eine bestimmte Denkhaltung und Herangehensweise. Software bleibt nur änderbar, wenn sie mit den beschränkten menschlichen Fähigkeiten im Einklang steht. Das gilt, sofern Software von Menschen und für Menschen gebaut wird. Die wichtigste Beschränkung liegt hierbei in der Fähigkeit, die <i>Folgen von Änderungen zu verstehen und zu beherrschen.</i> Das wird ermöglicht durch den sachgemäßen Ansatz von <i>Abstraktionen</i>. Durch einen Interface-Kontrakt wird die Implementierung zum Detail, und damit lokal änderbar. Für einen Kontrakt muss aber auch das Verhalten festgelegt werden. Damit dringt die Abstraktion in die Implementierung ein, und erfordert entsprechende Ausdrucksmittel. Der vorherrschende Lösungsansatz für diese Problematik war in den letzten 20 Jahren die Trennung von Infrastruktur und Funktionalität. Ein Stück Funktionalität wird zu einem abstrakten Element, das in einen anderweitig geregelten Kontrakt eingebunden werden kann. Einmal etabliert, könnte ein solches Schema oft an weiteren Stellen angewendet werden, sofern man auch noch von den konkreten Funktionsargumenten abstrahieren könnte. So entsteht die Forderung nach Funktionen auf generischen Argumenten. In der Praxis war der Weg dorthin mühsam und erforderte viele Workarounds. Die Sprachmittel in C++ waren anfangs wenig geeignet und problematisch: im Grunde gab es nur die schon in C nutzbaren Funktions-Pointer. Jedoch hat C++ durch seine Klassen und das Typsystem eine ausgeprägte Stärke im Bauen neuer Abstraktionen. Die Boost-Libraries haben daraus ein neues Sprachmittel geschaffen: <b>Funktions-Objekte</b>. Mit C++11 wurden diese auch Teil der Sprachdefinition; zugleich jedoch wurden auch <b>Lambda-Ausdrücke</b> als neues Sprachmittel eingeführt. Beide Sprachmittel stehen nun gleichberechtigt nebeneinander und ermöglichen völlig neue Anwendungsmuster. Und die Sprache entwickelte sich weiter. Mithilfe der <b>RValue-References</b> wurde das transparente Durchreichen von Argumenten möglich. Die hierfür notwendigen semantischen Anpassungen sind subtil und tückisch. Eine schrittweise Umstellung einer großen Codebasis ist ein langlaufender Vorgang und eine organisatorische Herausforderung. Oft muss man aber Argumente nicht nur durchreichen, sondern eine generische Funktion soll Eigenschaften ihrer Argumente verstehen und sich daran anpassen können. In den meisten älteren Programmiersprachen scheitert an dieser Forderung die Weiterentwicklung in Richtung einer Funktions-Abstraktion. Zum Glück (oder leider) galt das nicht für C++, denn während der Standardisierung der Sprache sind einige Design-Unfälle passiert, deren anfangs gar nicht intendiertes Verhalten in den Compilern dazu verwendet werden konnte, diese »Schallmauer« zu durchbrechen. Gemeint ist die <b>Template-Metaprogammierung</b>, eine Art »schwarze Magie«, mit der man eine funktionale Hilfs-Sprache während des Compilier-Vorgangs ausführen lassen kann. Warum lässt man sich auf schwarze Magie ein? Antwort: weil man dadurch mächtiger wird. Die Sprachmittel werden ausdrucksstärker. In wenigen Zeilen Code lässt sich eine komplexe Funktionalität zuverlässig und sicher realisieren. Dadurch gewinnt man Zeit, über die eigentlichen Anforderungen nachzudenken. Man geht damit aber technische Schulden ein: der Umgang mit der Codebasis erfordert vertiefte Kenntnisse, und einen mathematisch-geprägten Denkstil. Trotzdem war diese Entwicklung in der Praxis derart erfolgreich, dass das C++ - Komitee diesem Trend gefolgt ist, und die Aufgabe übernommen hat, die historisch gewachsene schwarze Magie in klar definierte und sauber verwendbare Sprachmittel inkrementell weiter zu entwickeln. Im Besonderen entstanden so <b>Variadische Ausdrücke</b> und <b>Concepts</b>. Wenn man diese Aufgabe ernst nimmt, kann man sich nicht damit begnügen, einen pragmatischen Gebrauch zu kodifizieren und syntaktisch nett zu verpacken. Vielmehr sind neue Sprachmittel gefordert, die sich zwar in den Stil der Sprache nahtlos einfügen, und auch das gleiche leisten wie die historisch gewachsene Lösung, aber dennoch auf einer neuen Basis stehen, klar definiert und leichter korrekt verwendbar sind. Das ist eine sehr anspruchsvolle Aufgabe; das Ergebnis ist erstaunlich, hat aber auch sehr viel Zeit in Anspruch genommen und ist in manchen Teilaspekten immer noch unfertig. Diese schrittweise Weiterentwicklung der Sprache führt dazu, dass im bestehenden Code eine Menge von Hilfsmitteln entsteht, die aufeinander aufbauen und weithin im Einsatz sind. Jedoch sind die Lösungen aus verschiedenen Entwicklungsstadien untereinander oft nicht kompatibel, da sich die gesamte Herangehensweise geändert hat. In einer größeren Code-Basis entstehen so komplexe interne Binding-Schichten, die erhebliche Probleme bei der Wartung aufwerfen können: zusammenhängende Systeme ziehen sich über weite Strecken durch den Code, und stützen sich jeweils auf Hilfsmittel ab, die untereinander nicht austauschbar sind. Beispiele hierfür sind: <ul><li>Loki-Typlisten vs. Variadic Arguments</li> <li>Type-Traits vs. Concepts</li> </ul> Da die jeweiligen Alternativen den gleichen Zweck auf unterschiedlichem Weg erreichen, kann eine Umstellung herausfordernd sein und läuft auf eine großflächige Überarbeitung etablierter Infrastrukturen hinaus. Daraus erwächst aber auch die Chance, in der Codebasis weithin etablierte Lösungen zu hinterfragen und weiterzuentwickeln. about this event: https://programm.froscon.org/2024/events/3133.html </description> <enclosure url="https://cdn.media.ccc.de/events/froscon/2024/h264-hd/froscon2024-3133-deu-Alt_werden_mit_C_hd.mp4" length="460324864" type="video/mp4"/> <pubDate>Sun, 18 Aug 2024 14:00:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/froscon/2024/h264-hd/froscon2024-3133-deu-Alt_werden_mit_C_hd.mp4?1723997684</guid> <dc:identifier>2cd8e2e5-2a46-413b-99cd-7ec6ddf20531</dc:identifier> <dc:date>2024-08-18T14:00:00+02:00</dc:date> <itunes:author>Hermann Voßeler</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>froscon2024, 3133, 2024, Development</itunes:keywords> <itunes:subtitle>Wenn ein langlebiges Projekt mit der Weiterentwicklung der Sprache mitwächst</itunes:subtitle> <itunes:summary>Für eine langlebige Codebasis ist der Charakter und die weitere Entwicklung der einmal gewählten Programmiersprache bedeutsam.

Hence, professors in computer science and connected disciplines should raise awareness for topics such as digital sovereignty or free and open source software. This talk reflects on attempts to include these aspects in the curriculum - not only by specific lectures but also by motivating students to make the results of their projects and theses available to the general public under open source licenses. The talk showcases some "lighthouse projects" but also discusses challenges - especially when it comes to maintaining work once it has been graded. Vendors of proprietary software invest substantial time and money to win teachers and professors as lobbyists for their products. But how can members of the free and open source communities counter these attempts? And how can we provide students with the ability to make fair and well-balanced decisions about licenses and technology later on? While many computer science students use open source software during their studies and later at work, important basics about licensing or open source communities are often not part of the curriculum. However, since the students of today are often the decision makers of tomorrow it seems crucial to enable students to make well-informed decisions - not only regarding technological aspects but also incorporating ethical issues and sociological goals connected to digital sovereignty. I have spent more than 15 years with teaching activities at various universities. During this time, I made several attempts to raise open source awareness and achieved remarkable progress in making results of student projects available as open source software to the general public. This talk reflects on possible strategies with their pros and cons. Furthermore, it discusses challenges that often arise - such as selecting proper technologies or motivating students to continue their work after their project has been graded. about this event: https://programm.froscon.org/2024/events/3130.html </description> <enclosure url="https://cdn.media.ccc.de/events/froscon/2024/h264-hd/froscon2024-3130-eng-Making_Open_Source_education_an_integral_part_of_the_curriculum_in_Computer_Science_programs_hd.mp4" length="382730240" type="video/mp4"/> <pubDate>Sat, 17 Aug 2024 17:45:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/froscon/2024/h264-hd/froscon2024-3130-eng-Making_Open_Source_education_an_integral_part_of_the_curriculum_in_Computer_Science_programs_hd.mp4?1723966740</guid> <dc:identifier>54b18253-7664-419f-8b4b-ac700468a5c1</dc:identifier> <dc:date>2024-08-17T17:45:00+02:00</dc:date> <itunes:author>Daniel Kulesz</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>froscon2024, 3130, 2024, Bridging the Gap between politics and reality - Open Source Lobbying</itunes:keywords> <itunes:subtitle>A personal reflection</itunes:subtitle> <itunes:summary>The students of today are the decision-makers of tomorrow.

Ublue-OS bootet direkt in einen OCI-Container, was die Erstellung eines immuntable Desktops vereinfacht und für eine robuste Sicherheit und Stabilität sorgt. Durch die Trennung von Betriebssystem und Anwendungen mittels Technologien wie Flatpak sowie die Integration von Distrobox für die nahtlose Verwaltung von Anwendungen, bietet der Immuntable Desktop eine sichere, stabile und benutzerfreundliche Desktop-Umgebung. Praktische Demonstrationen verdeutlichen die einfache Erstellung und Anpassung des Desktops sowie die Durchführung von Updates und Rollbacks. Der Vortrag zeigt auf, wie Ublue-OS den Brückenschlag zwischen Desktop und Cloud-Technologien vollzieht und somit die Zukunft des Desktop-Computings maßgeblich gestaltet. Der Immuntable Desktop mit Ublue-OS markiert einen Wendepunkt in der Evolution des Desktop-Computings. In einer Zeit, in der Sicherheit und Stabilität oberste Priorität haben, bietet dieser Ansatz eine revolutionäre Lösung für die Herausforderungen, denen herkömmliche Desktop-Betriebssysteme gegenüberstehen. Ublue-OS bootet direkt in einen OCI-Container, was bedeutet, dass die Erstellung eines immuntable Desktops kein spezielles Know-how erfordert, wie es bei NixOS der Fall ist. Stattdessen können Sie einfach ContainerFiles (Dockerfiles) verwenden, um Ihren individuellen Desktop nach Ihren Bedürfnissen zu erstellen und anzupassen. Im Rahmen dieses Vortrags erhalten Sie einen umfassenden Einblick in die Vorteile des Immuntable Desktops mit Ublue-OS: Sicherheit: Durch die strikte Trennung von Betriebssystem und Anwendungen mittels Technologien wie Flatpak wird der Immuntable Desktop zu einer Festung gegenüber potenziellen Bedrohungen. Malware und unerwünschte Manipulationen haben keine Chance, das System zu kompromittieren. Stabilität: Dank des immuntable Ansatzes bleiben Ihre Systeme konsistent und stabil, selbst nach Updates oder Änderungen. Rollbacks ermöglichen es, bei Bedarf schnell zu einer zuverlässigen vorherigen Version zurückzukehren, ohne dass dabei Datenverlust oder Unterbrechungen auftreten. Benutzerfreundlichkeit: Die Erstellung und Anpassung eines immuntable Desktops mit Ublue-OS ist dank der Verwendung von ContainerFiles (Dockerfiles) einfach und zugänglich. Dies ermöglicht eine schnelle Bereitstellung und Verwaltung von individuellen Desktop-Konfigurationen, ohne dass spezielles technisches Know-how erforderlich ist. Zusätzlich ermöglicht Distrobox die nahtlose Integration von Anwendungen durch die Nutzung von Containern, was die Bereitstellung und Verwaltung weiter vereinfacht. In diesem Vortrag werden auch praktische Demonstrationen durchgeführt, um Ihnen einen realistischen Einblick in die Funktionsweise des Immuntable Desktops mit Ublue-OS zu geben. Sie werden sehen, wie einfach es ist, einen individuellen Desktop zu erstellen, Updates durchzuführen, Rollbacks durchzuführen und Anwendungen sicher und effizient zu nutzen. Der Immuntable Desktop mit Ublue-OS bietet eine Antwort auf die wachsenden Anforderungen an Sicherheit, Stabilität, Benutzerfreundlichkeit und erleichtert die Verwaltung von Anwendungen durch die Integration von Distrobox. about this event: https://programm.froscon.org/2024/events/3039.html </description> <enclosure url="https://cdn.media.ccc.de/events/froscon/2024/h264-hd/froscon2024-3039-deu-Next-Gen_Desktops_Ublue-OS_immutable_desktop_hd.mp4" length="713031680" type="video/mp4"/> <pubDate>Sat, 17 Aug 2024 16:30:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/froscon/2024/h264-hd/froscon2024-3039-deu-Next-Gen_Desktops_Ublue-OS_immutable_desktop_hd.mp4?1723918943</guid> <dc:identifier>207e7724-8f58-4bfe-97bd-53894d797f37</dc:identifier> <dc:date>2024-08-17T16:30:00+02:00</dc:date> <itunes:author>Christoph Stoettner (stoeps)</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>froscon2024, 3039, 2024, Cloud</itunes:keywords> <itunes:subtitle>Booten wir in einen Container</itunes:subtitle> <itunes:summary>Der Vortrag präsentiert den Immuntable Desktop mit Ublue-OS als wegweisende Entwicklung im Bereich des Desktop-Computings.

In diesem Vortrag werden auch praktische Demonstrationen durchgeführt, um Ihnen einen realistischen Einblick in die Funktionsweise des Immuntable Desktops mit Ublue-OS zu geben. Sie werden sehen, wie einfach es ist, einen individuellen Desktop zu erstellen, Updates durchzuführen, Rollbacks durchzuführen und Anwendungen sicher und effizient zu nutzen. Der Immuntable Desktop mit Ublue-OS bietet eine Antwort auf die wachsenden Anforderungen an Sicherheit, Stabilität, Benutzerfreundlichkeit und erleichtert die Verwaltung von Anwendungen durch die Integration von Distrobox. about this event: https://programm.froscon.org/2024/events/3039.html </itunes:summary> <itunes:duration>00:58:39</itunes:duration> </item> <item> <title>kivitendo - OpenSource ERP für den Saatgutanbau (froscon2024)</title> <link>https://media.ccc.de/v/froscon2024-3052-kivitendo_-_opensource_erp_fur_den_saatgutanbau</link> <description>Implementierung, Anpassungen und Einführung eines Opensource für den Saatgut-Anbau und Handel.

Die Verwendung von SecureBoot stellt Administratoren vor gewisse Herausforderungen wenn Hosts automatisiert aufgesetzt werden sollen. Das Open-Source-Projekt Foreman, welches als Basis für orcharhino und RedHat's Satellite dient, ist ein Lifecycle-Management-Tool, das u.a. ein automatisiertes Aufsetzen von Hosts ermöglicht. Mein Vortrag soll eine kurze Einführung in SecureBoot geben, Foreman's Provisionierungsmöglichkeiten, und dessen aktuelle Limitierungen sowie den aktuellen Stand der Upstream-Entwicklung in Bezug auf den SecureBoot-Support. Das Unified Extensible Firmware Interface (UEFI), bis Version 2.0 auch bekannt als EFI, wurde als BIOS-Nachfolger eingeführt und hat sich als Standard heutiger Hardwareplattformen durchgesetzt.

In this talk, we present processes and operational practices for a "day 2" Linux operating system to run Container and Kubernetes workloads at scale - with examples and a few demos on Flatcar Container Linux. about this event: https://programm.froscon.org/2024/events/3103.html </itunes:summary> <itunes:duration>00:54:15</itunes:duration> </item> <item> <title>Jeder Meter Zählt (froscon2024)</title> <link>https://media.ccc.de/v/froscon2024-3137-jeder_meter_zahlt</link> <description>Dieser Vortrag gibt einen Einblick in die Arbeit eines Systemadministrator bei der Deutsche Börse.

Der MySQL-Code, die fertigen Binaries (aka MySQLCommunity Edition) und auch die kommerzielle MySQL-Version stehen auf den bekannten Webseiten zum Download bereit. Doch was hat sich geändert, wo liegen die Herausforderungen? All das wird in diesem Vortrag erläutert... Wie üblich bringt ein neues Release einer Datenbank nicht nur neue Funktionalitäten mit sich, sondern auch einige, die eingestellt wurden. Und natürlich stellt sich die Frage, wie man von einem 'alten' Release auf ein 'neues' Release migriert.

Huey is blazing fast, courtesy of DuckDB / WASM. It can load data in .csv, .parquet or JSON format, and it can also open DuckDB database files. Huey's key features are: - An intuitive and responsive pivot table that supports filtering and (sub)totals - Supports many different aggregate functions for reporting and data exploration - Automatic breakdown of date/time columns into separate parts (year, month, quarter etc) for reporting - Supports reading .parquet, .csv, .json and .duckdb database files. (Support for reading MS - Excel .xlsx files and .sqlite is planned) - Export of results and/or SQL queries to file or clipboard - Blazing fast, even for large files - courtesy of DuckDB - Zero install. Download or checkout the source tree, and open src/index.html in your browser! No server required. Note: although Huey can run locally, there is nothing that keeps you from deploying it in a webserver if you want to. DuckDB / WASM enables web developers to build light-weight OLAP and analytics applications directly in the browser. Thanks to DuckDB, performance is blazing fast, while memory consumption remains modest. In this lecture I will demonstrate Huey's features and explain how it was build using DuckDB / WASM DuckDB as well as Huey are open source under a permissive MIT license.

Searching for vectors has now become a key requirement of databases in order to facilitate AI first applications. MariaDB Server will introduce Vector similarity search in an upcoming release. In this talk we will discuss what MariaDB vector is, how it works behind the scenes, as well as possible use cases and future roadmap. MariaDB Vector introduces a new high-level interface for indexing within MariaDB Server. This interface allows one to create custom indexing strategies. Vector search requires a special kind of index. The algorithm that is used by MariaDB and many other vector databases is called Hierarchical Navigable Small Worlds (HNSW). In this talk we will focus on the basis of HNSW, why the algorithm returns approximate results and what impacts its performance (tuning parameters). We will also discuss the difference between a Generative AI model and an Embedding AI model and how they can be used to build Retrieval Augmented Generation applications using MariaDB as a datastore. Finally we'll describe the current eco-system of Vector databases what are their strengths and weaknesses.

Kann so eine strukturierte und modulare Möglichkeit gefunden werden, um umfangreiche Stylesheets lesbar zu halten und einfacher zu warten? Wie sind uns dabei die neuen CSS Features der letzten Jahre von Nutzen? In der Welt der Softwareentwicklung wird oft über sauberen Code in Programmiersprachen gesprochen, aber wie steht es um CSS? Zumal CSS sehr häufig zum Einsatz kommt und der Umgang mit CSS schnell äußerst kompliziert und unzugänglich wird. In diesem Vortrag betrachten wir den Versuch, die Prinzipien von Clean Code auf CSS anzuwenden, um CSS flexibel, lesbar, wartbar und erweiterbar zu machen. Wir beleuchten nicht nur bewährte Methoden, sondern auch einige der Neuerungen im CSS-Bereich der letzten Jahre, die diese Ziele unterstützen. Dazu gehören CSS-Variablen und neue Pseudoklassen. Dieser Vortrag präsentiert keine fertige Lösung aus langjähriger Erfahrung, sondern versteht sich als Ansatz und Betrachtung, wie Clean-Code-Prinzipien genutzt werden können, um CSS noch besser zu strukturieren und neue, elegante Lösungen zu finden. Egal, ob Sie ein erfahrener Entwickler oder ein Anfänger sind, dieser Vortrag bietet wertvolle Einblicke und praktische Tipps für die tägliche Arbeit mit CSS. about this event: https://programm.froscon.org/2024/events/3150.html </description> <enclosure url="https://cdn.media.ccc.de/events/froscon/2024/h264-hd/froscon2024-3150-deu-Clean_CSS_hd.mp4" length="438304768" type="video/mp4"/> <pubDate>Sat, 17 Aug 2024 11:15:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/froscon/2024/h264-hd/froscon2024-3150-deu-Clean_CSS_hd.mp4?1723897278</guid> <dc:identifier>abf0978c-0f33-46df-ac6b-a0df7a416a23</dc:identifier> <dc:date>2024-08-17T11:15:00+02:00</dc:date> <itunes:author>Andreas Gartz</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>froscon2024, 3150, 2024, Web Development</itunes:keywords> <itunes:subtitle>Wie können Clean Code Prinzipien auf CSS angewendet werden?</itunes:subtitle> <itunes:summary>Können die Prinzipien von Clean Code auf CSS angewendet werden?

WKD (Web Key Directory) ist ein Standard, der die Verbreitung von OpenPGP-Keys via HTTPS beschreibt, wobei jeweils pro Domain festgelegt wird, von wo die Keys bezogen werden. DANE (DNS-based Authentication of Named Entities) ist ein Standard, der beschreibt, wie Public Keys (neben TLS- auch S/MIME- und OpenPGP-Keys) via DNSSEC-signierter DNS-Records verbreitet werden können.

Das Oszilloskop ist neben dem Multimeter das wichtigste Messmittel in der Elektronik, weil man "sehen" kann was der Strom da so tut. Leider ist die Bedienung eines Oszilloskop nicht ganz einfach und braucht auch Übung.

Join me on a journey from Erlang to OCaml and back again. We’ll learn about Caramel 🍬 – an experiment in bringing type-safety for the Erlang VM. Caramel was born out of the question: why is Erlang hard to type? – and as it turns out, it is not! If you restrict it enough. So much so that what you end up with is…OCaml? On the flip side, the new algebraic effects and multicore capabilities of OCaml 5 open the possibility of new execution models. How far could we take them? Could we inject Erlang’s famed concurrency model into OCaml?

They are becoming increasingly popular in the blockchain space, as they provide solutions to overcome inherent weaknesses of blockchains: as they assume a complete lack of trust between participants, every calculation has to be replicated by multiple parties, which leads to poor efficiency. Also, blockchains provide a shared public ledger, which by default is lacking any privacy. In this presentation, we will discuss zero-knowledge succinct non-interactive arguments of knowledge (zkSNARKS). Using the mina blockchain and smart contract system as an example, we will show how they can be used to efficiently create trust in an untrusted environment. We will also look at how they allow creating applications with a programmable degree of privacy. While zero knowledge techniques are a perfect match for blockchains, and they are rapidly gaining traction in that industry, their usefulness goes beyond that. The goal of this presentation is to introduce the audience to the concept of zero knowledge proofs, and provide a basic understanding and intuition of how they work, and under which circumstances they can be useful. about this event: https://bobkonf.de/2024/kant.html </description> <enclosure url="https://cdn.media.ccc.de/events/bobkonf/2024/h264-hd/bob2024-15-eng-Zero-Knowledge-Proofs_for_Privacy_and_Trust_hd.mp4" length="118489088" type="video/mp4"/> <pubDate>Fri, 15 Mar 2024 17:10:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/bobkonf/2024/h264-hd/bob2024-15-eng-Zero-Knowledge-Proofs_for_Privacy_and_Trust_hd.mp4?1720977798</guid> <dc:identifier>5fb44183-40d6-44de-872e-72b8d8f0f7c8</dc:identifier> <dc:date>2024-03-15T17:10:00+01:00</dc:date> <itunes:author>Philipp Kant</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>bob2024, 15, 2024, Talk, BOB, BOBKonferenz</itunes:keywords> <itunes:summary>Zero-knowledge proofs are cryptographic techniques that allow a prover to convince a verifier that certain statements hold, without providing any additional information.

You rarely hear Swift being mentioned. This is odd, as one might argue that, of these languages, Swift places the strongest emphasis on functional programming. In this talk, I will explain the core functional programming features of Swift, including its expressive type system, value types, and mutability control. Furthermore, I will discuss how Swift’s language design is influenced by the desire to create a language that addresses the whole spectrum from low-level systems programming up to high-level applications with sophisticated graphical user interfaces. Beyond the core language itself, functional programming also permeates Swift’s rich ecosystem of libraries. To support this point, I will outline some FP-inspired core libraries, covering concepts from functional data structures over functional reactive programming to declarative user interfaces. Finally, I will briefly summarise practical considerations for using Swift in your own projects. This includes the cross-platform toolchain, the package manager, and interoperability with other languages. about this event: https://bobkonf.de/2024/chakravarty.html </description> <enclosure url="https://cdn.media.ccc.de/events/bobkonf/2024/h264-hd/bob2024-10-eng-Functional_Programming_in_Swift_hd.mp4" length="134217728" type="video/mp4"/> <pubDate>Fri, 15 Mar 2024 11:45:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/bobkonf/2024/h264-hd/bob2024-10-eng-Functional_Programming_in_Swift_hd.mp4?1720964119</guid> <dc:identifier>a064fb6e-5975-46bb-94df-5ab0f98dd325</dc:identifier> <dc:date>2024-03-15T11:45:00+01:00</dc:date> <itunes:author>Manuel Chakravarty</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>bob2024, 10, 2024, Talk, BOB, BOBKonferenz</itunes:keywords> <itunes:summary>When people talk about functional programming in modern multi-paradigm languages, they usually mention Rust, Scala, or Kotlin.

I will show how you can get quick and actionable alerts in case of system failures. You will learn how to use modern open source tools to receive timely notifications and information regarding your Linux systems. While email has traditionally been used to notify of IT system failures, it might not be suitable these days since there’s increased mobility. I will show how you can receive critical alerts on your mobile devices such as cellphones using XMPP Messaging. Alerts can also be sent in the form of voice notifications to smart home or office speakers. During this talk, you will also learn how to set up monitoring processes that watch for any signs of trouble on your Linux system. For example: High and unusual CPU usage, low memory, low storage space or failing hard disks, overheating, application failures. For application failures such as web and database services, I will share smart techniques you can use to recover with as little manual interaction as possible. Furthermore, I will outline the different open source based monitoring solutions that currently exist and how they can easily be installed and deployed on your Linux system.

I will show how you can get quick and actionable alerts in case of system failures. You will learn how to use modern open source tools to receive timely notifications and information regarding your Linux systems. While email has traditionally been used to notify of IT system failures, it might not be suitable these days since there’s increased mobility. I will show how you can receive critical alerts on your mobile devices such as cellphones using XMPP Messaging. Alerts can also be sent in the form of voice notifications to smart home or office speakers. During this talk, you will also learn how to set up monitoring processes that watch for any signs of trouble on your Linux system.

It has had a great impact on both industries and our day-to-day lives, and with the recent advancements in AI technology, robotics will only get more important. Open source principles have been instrumental in driving progress in various fields, and it is true for robotics as well. A lot of software used in the field is open source, for example, ROS (Robot Operating System) and Gazebo etc. Linux distros like Ubuntu and Fedora have already established themselves as well known players in the robotics community. However, there is unique opportunity for openSUSE to carve its niche in this domain. This talk aims to explore this opportunity and outline a roadmap for building a robotic ecosystem with openSUSE. Drawing inspiration from existing initiatives such as Ubuntu's Robotics community and Fedora's Robotics Suite, I will propose ways to enhance openSUSE's relevance in the landscape. This includes the creation of specialized packages optimized for robotics applications, establishing partnerships with universities and research institutions to promote openSUSE adoption, and make a vibrant community of robotics enthusiasts and developers. Attendees can expect to gain insights into the pivotal role of open source in robotics and practical steps to advance openSUSE as a preferred platform.

(osc24)</title> <link>https://media.ccc.de/v/4438-why-to-log-centrally</link> <description>Why is central logging so important? Convenience, availability and security. Convenience, as you have a single place to check instead of many. Availability, as you can check log messages, even if the sending host is unavailable. Security, as logs leave hosts as soon as they are produced, so an attacker has no chance to modify them. Developers, operators, and security have a single view of the whole network and can easily correlate events from multiple hosts. Often, the various tools to analyze log messages provide you with their own agents to forward logs to SIEM or other analytics tools. However, this is inefficient for several reasons. Most importantly, it is a waste of computing resources. You install multiple applications to do the same job: forwarding log messages. And these messages then travel through your network multiple times. So, what you should do instead is build a dedicated log management layer for central log collection. This ensures that log messages are collected only once. Using the OpenTelemetry protocol, logs, traces and metrics can be collected together, simplifying the architecture of collecting data about your infrastructure even further. From this talk, you can learn how to implement central logging using syslog-ng and how OpenTelemetry changes logging. Syslog-ng in openSUSE Tumbleweed already supports the OpenTelemetry protocol.

Many of them derive from the limitations imposed by resource-constrained edge devices, infrastructure heterogeneity, and the need to meet criteria such as performance, resilience, security, data sovereignty, and energy efficiency. To overcome these obstacles, the EU project COGNIT (https://cognit.sovereignedge.eu/) is developing a new distributed Function-as-a-Service (FaaS) platform that enables application developers to off-load tasks to a cognitive computing continuum. Through Artificial Intelligence enabled orchestration and automation, this Horizon Europe project will implement a disaggregated architecture that fits the nature of edge environments and abstracts the complexities of the underlying cloud-edge infrastructure. It enables for dynamically managing and adapting resources and workloads in response to incidents, security aspects, and other metrics that are relevant to the evolving needs of the workloads and applications. In this talk we will explore some of the sectors and use cases—including Industry & Manufacturing, Smart Cities, Cybersecurity, Wildfire Detection, Energy—in which the open source technology that we are developing in this project will bring an immediate benefit to IoT/edge application developers and end-users.

This happens with a 32bit time_t, not with a 64bit time_t. The general statement so far has always been that on 64bit systems with a 64bit time_t you are safe with respect to the Y2038 problem. But this isn't correct: on bi-arch systems like x86-64 (so which can execute 64bit and 32bit binaries) glibc defines __WORDSIZE_TIME64_COMPAT32, which leads to the fact, that struct utmp (used for utmp, wtmp and btmp) and struct lastlog uses int32_t instead of time_t. So we have a Y2038 problem, which is not easy fixable, as this would require ABI and on disk format changes. In this talk I will speak about the background, which tools are affected and how we solved that in openSUSE by dropping utmp, wtmp, btmp and lastlog completely and make use of systemd-logind and other tools instead.

With automated patch and package management, it enables the deployment of patches and packages based on software channels and repositories that can be assigned. Uyuni makes it easier to onboard and manage any Linux server connected to the network, from IoT edge devices to Kubernetes environment, no matter where it is located (private or 3rd party data center or in the public cloud). Uyuni is a single tool for automated deployment of hardened OS templates (bare metal/VM/container) to tens of thousands of servers and IoT devices for faster, consistent and repeatable provisioning and configuration without compromising speed or security. The CVE audit feature allows to check the status of public security patches and with OpenSCAP it's also possible to check for specification compliance and apply remediations right from Uyuni.

Remote attestation can be a measure to maximize trust, security and privacy when using a mobile telecommunications network. In this talk, I give a rough overview on how a mobile network works, followed by some insight into ongoing threats the public mobile network is facing in the past years. As a solution to some of the threats, remote attestation is a heavily discussed topic in research, and even from the mobile equipment vendors. I give an introduction into the topic of remote attestation and how and where it can be used in mobile networks and how it might impact the performance. about this event: https://cfp.fairydust.reisen/iger-2024/talk/YCWG7K/ </description> <enclosure url="https://cdn.media.ccc.de/events/iger/2024/h264-hd/import-56226-deu-Remote_Attestation_in_5G_Networks_hd.mp4" length="187695104" type="video/mp4"/> <pubDate>Sat, 08 Jun 2024 21:30:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/iger/2024/h264-hd/import-56226-deu-Remote_Attestation_in_5G_Networks_hd.mp4?1717893828</guid> <dc:identifier>ed8004e5-e5fe-4e39-a55c-851f42765733</dc:identifier> <dc:date>2024-06-08T21:30:00+02:00</dc:date> <itunes:author>Gvinevere</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>import, 56226, 2024</itunes:keywords> <itunes:summary>The ongoing digitization of the society and services call for a high availability of secure mobile networks, like 5G.

As a solution to some of the threats, remote attestation is a heavily discussed topic in research, and even from the mobile equipment vendors. I give an introduction into the topic of remote attestation and how and where it can be used in mobile networks and how it might impact the performance. about this event: https://cfp.fairydust.reisen/iger-2024/talk/YCWG7K/ </itunes:summary> <itunes:duration>00:30:35</itunes:duration> </item> <item> <title>KI und Schule - über modernen Götzenkult (iger-2024)</title> <link>https://media.ccc.de/v/iger-2024-56222-ki-und-schule-uber-moder</link> <description>KI ist der neue Hype und Schulen drehen durch.

Diese Frage habe ich mir vor ein paar Jahren gestellt und eine "virtuelle" Maschine entwickelt, also eine Maschine, die am Computer "funktioniert". Aber würde so eine Maschine sich auch tatsächlich bauen lassen. Bei der virtuellen Maschine gibt es keine physikalischen Einschränkungen und Herausforderungen wie zum Beispiel Gravitation oder Reibung. In diesem Talk stelle ich einen funktionierenden Prototyp vor. Primzahlen haben Mathematiker und mathematisch interessierte schon immer fasziniert. Und Schüler hassen sie - meistens. In unserer modernen Welt sind sie auch essentiell für Verschlüsselungen. Der Grundgedanke bei den asymmetrischen Verschlüsselungsverfahren basiert auf Primzahlen. Aber wie kann man feststellen, ob es sich bei einer Zahl um eine Primzahl handelt? Mit moderner Technik ist das kein Problem. Aber rein mechanisch? Wie ich in einem anderem Talk gezeigt habe ist so eine Maschine virtuell problemlos möglich. Wie verhält es sich aber in der realen Welt? Wenn man Gravitation, Reibung und andere physikalische Gesetze nicht einfach ignorieren beziehungsweise deaktivieren kann. Funktioniert das immer noch? Ja! Und zu diesem Vortrag bringe ich den ersten Prototypen mit und zeige euch unter anderem, wie man damit Primzahlen ermitteln kann, Divisionen durchführen, eine Zahl in ihre Teiler zerlegen sowie eine Zahl in ein anderes Zahlensystem umrechnen kann. Insgesamt erwartet euch folgendes in diesem Talk: - Feststellen, ob eine Zahl gerade oder ungerade ist - Divisionen mit und ohne Rest durchführen - Eine Zahl in ihre Teiler zerlegen - Eine Zahl in ihre Primfaktoren zerlegen - Feststellen, ob eine Zahl eine Primzahl ist - In Zahlensysteme umrechnen, zum Beispiel in das Binärsystem - Quadratwurzeln berechnen bzw. abschätzen Ob es so eine Maschine jemals wirklich gab und ob sie einen Nutzen hatte beziehungsweise gehabt hätte, weiß ich nicht. Sie ist aber gut geeignet, Primzahlen und andere mathematische Methoden zu visualisieren. Interessant für Lehrer, die ihren Schülern die Primzahlen und andere mathematische Methoden näher bringen beziehungsweise vermitteln wollen. about this event: https://cfp.gulas.ch/gpn22/talk/WDWBUA/ </description> <enclosure url="https://cdn.media.ccc.de/events/gpn/gpn22/h264-hd/gpn22-293-deu-Und_sie_existiert_doch_-_die_fast_unmoegliche_Primzahlenerkennungsmaschine_hd.mp4" length="2054160384" type="video/mp4"/> <pubDate>Thu, 30 May 2024 16:30:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/gpn/gpn22/h264-hd/gpn22-293-deu-Und_sie_existiert_doch_-_die_fast_unmoegliche_Primzahlenerkennungsmaschine_hd.mp4?1717140113</guid> <dc:identifier>27249786-0e21-5b47-9e20-87c81624815c</dc:identifier> <dc:date>2024-05-30T16:30:00+02:00</dc:date> <itunes:author>Tom Gries (TOMO)</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>gpn22, 293, 2024, Science</itunes:keywords> <itunes:summary>Ist es möglich, eine Maschine zu bauen, mit der man Primzahlen erkennen bzw. ermitteln kann?

Aber gerade in den letzten Jahren hat sich einiges getan, um diesen Status zu verbessern, sowohl seitens Nvidias als auch in der Wayland-Community. Und dank großer Fortschritte im Nouveau-Projekt sind Anwender:innen nicht mehr alleine auf Nvidia angewiesen, auch ein vollkommen offener Grafikstack scheint wieder in greifbarer Nähe. Daher stelle ich mir 2024 wieder die Frage: Lässt sich Wayland endlich problemlos mit Nvidia-GPUs nutzen? Seit 2021 gab es einige Meilensteine, die die Unterstützung von Wayland auf Nvidia-GPUs Stück für Stück verbessert haben. Dies geht von der teilweisen Öffnung der offiziellen Nvidia-Treiber über eine Annäherung Nvidias an die Wünsche der Wayland-Community bis zu den kürzlichen Fortschritten des Nouveau-Projekts, aktuelle Nvidia-GPUs nicht nur zu unterstützen, sondern auch offene Treiber für Vulkan und OpenGL zu liefern, die vollkommen standardkonform sind. Es scheint also, als könnte dies das Jahr des Nvidia-Linux-Desktops werden. In diesem Talk wollen wir uns anschauen, was mittlerweile alles möglich ist, sowohl in Bezug auf Gaming als auch die alltägliche Nutzung des Desktops. Welche Unterschiede gibt es dabei zwischen den verschiedenen Desktopumgebungen? Wie viel manuelle Konfiguration ist noch notwendig, um das beste Wayland-Erlebnis zu erreichen? Und lohnt sich der Umstieg auf Nouveau? Einige nennenswerte Fortschritte der letzten Jahre sind: - Juli 2021: Xwayland, die Kompatibilitätsschnittstelle, um X11-Anwendungen innerhalb einer Wayland-Umgebung auszuführen, erhält Hardwarebeschleunigung für Nvidia-GPUs. Da gerade Spiele (und Wine/Proton) vorrangig nur unter X11 laufen, wird Wayland zum ersten Mal für Spieler:innen mit Nvidia-GPUs interessant. - Oktober 2021: Nvidia veröffentlicht die erste Treiberversion mit Unterstützung für Generic Buffer Management (GBM), einer offenen Schnittstelle zum allokieren von Render Target Buffers, die in allen Wayland Compositors zum Einsatz kommt. Zuvor hatte Nvidia versucht, die eigene Lösung EGLStreams als "bessere" Alternative zu etablieren. - Mai 2022: Nvidia veröffentlicht die "GPU Open-Source Kernel Modules", welche die "sensiblen" Teile des Nvidia-Kernel-Treibers in einen geschlossenen RISC-V-Prozessor auf Hardware-Seite (genannt GPU System Processor, kurz GSP) verschieben und es Nvidia ermöglichen, nur die Kommunikationsschnittstelle für diesen als Open Source zu veröffentlichen. Die Userland-Teile des Treibers (CUDA, OpenGL, Vulkan, DLSS) bleiben weiterhin Closed Source. - August 2023: Der offene Vulkan-Treiber NVK des Nouveau-Projekts wird dem Linux-Grafikstack Mesa hinzugefügt. Dank des Vulkan-basierten OpenGL-Treibers Zink unterstützt Nouveau damit sowohl Vulkan als auch aktuelle OpenGL-Versionen. - Oktober 2023: Nvidia fügt Unterstützung für Gamma Lookup Tables (Gamma LUT) hinzu. - November 2023: Der offene Linux-Kernel-Treiber Nouveau fügt Unterstützung für den GSP hinzu, welcher es ihm zum ersten Mal in fast 10 Jahren erlaubt, die Taktrate auch auf neueren Nvidia GPUs zu verändern und damit einen performanten Einsatz möglich macht. - November 2023: NVK erreicht volle Konformität für Vulkan 1.0. - Februar 2024: NVK erreicht volle Konformität für Vulkan 1.3. about this event: https://cfp.gulas.ch/gpn22/talk/FFJ8QT/ </description> <enclosure url="https://cdn.media.ccc.de/events/gpn/gpn22/h264-hd/gpn22-265-deu-Sind_wir_schon_Wayland_Nvidia_Edition_hd.mp4" length="1082130432" type="video/mp4"/> <pubDate>Sat, 01 Jun 2024 21:15:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/gpn/gpn22/h264-hd/gpn22-265-deu-Sind_wir_schon_Wayland_Nvidia_Edition_hd.mp4?1717283228</guid> <dc:identifier>1fa8f4c7-0482-592b-8d70-8fc59b349bd5</dc:identifier> <dc:date>2024-06-01T21:15:00+02:00</dc:date> <itunes:author>Niklas Korz</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>gpn22, 265, 2024, Software & Infrastructure</itunes:keywords> <itunes:summary>Die schlechte Unterstützung von Wayland unter Nvidia-Treibern hat zurecht einen Meme-Status erreicht.

(gpn22)</title> <link>https://media.ccc.de/v/gpn22-271-cyber-resilience-act-compliance-risk-oder-consumer-respect-act-</link> <description>Der Cyber Resilience Act (CRA) legt Herstellern von Software und auch Open Source Communities strenge Regeln in Bezug auf IT-Sicherheit ihrer Produkte auf. Dieser Vortrag gibt zunächst einen Überblick über die Ziele und Inhalte dieses Gesetzes. Der Schwerpunkt liegt auf den geforderten technischen und administrativen Regelungen und Verpflichtungen. Es wird erläutert, worauf sich Hersteller, Open Source Communities und Verbraucher einstellen müssen und eingeordnet, wie praktikabel und effektiv die Vorgaben möglicherweise sind. Mit dem CRA hat die EU-Kommission eine Verordnung auf den Weg gebracht, die die IT-Sicherheit von Produkten reguliert, mit der Motivation, die Interessen der Verbraucher zu stärken und die EU insgesamt widerstandsfähiger gegen Cyberangriffe zu machen. Dieses Gesetz legt Anforderungen für "Produkte mit digitalen Elementen" fest. Von Herstellern wird die Erstellung einer Cybersicherheitsrisikobewertung und die Bereitstellung von Sicherheitsupdates verlangt. Bestimmte alltägliche Softwareprodukte, wie Betriebssysteme, Browser und Password-Manager, werden als "wichtige Produkte" eingestuft. Diese werden auf die Einhaltung von grundlegenden IT-Sicherheitsanforderungen überprüft. Auch Open-Source-Software und ihre Communities werden von diesem Gesetz betroffen sein. Es wird gefordert, dass diese eine Cybersicherheitsstrategie vorlegen, welche unter anderem den Umgang mit Schwachstellen regelt. Ein Verstoß gegen die Bestimmungen kann mit bis zu 15 Millionen Euro oder 2,5 % des Weltweiten Jahresumsatzes geahndet werden. Des Weiteren wird die ENISA eine Meldeplattform anbieten, über welche Hersteller Schwachstellen melden. In Hinblick auf die Praktikabilität und Effektivität stellen sich eine Reihe von Fragen, auch sind noch nicht alle Details bekannt, z.B. die Spezifikation von SBOMs. *TL; DR: Neues EU-Gesetz, welches Hersteller verpflichtet (IT-)sicherere Produkte zu entwickeln.* about this event: https://cfp.gulas.ch/gpn22/talk/AUEQH7/ </description> <enclosure url="https://cdn.media.ccc.de/events/gpn/gpn22/h264-hd/gpn22-271-deu-Cyber_Resilience_Act_-_Compliance_Risk_oder_Consumer_Respect_Act_hd.mp4" length="743440384" type="video/mp4"/> <pubDate>Sun, 02 Jun 2024 12:30:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/gpn/gpn22/h264-hd/gpn22-271-deu-Cyber_Resilience_Act_-_Compliance_Risk_oder_Consumer_Respect_Act_hd.mp4?1717335405</guid> <dc:identifier>127858e4-3476-55f1-8242-78cd57ada21f</dc:identifier> <dc:date>2024-06-02T12:30:00+02:00</dc:date> <itunes:author>Markus Toran, Deleted User</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>gpn22, 271, 2024, Security</itunes:keywords> <itunes:summary>Der Cyber Resilience Act (CRA) legt Herstellern von Software und auch Open Source Communities strenge Regeln in Bezug auf IT-Sicherheit ihrer Produkte auf.

Now it is time to move forward. This workshop is focused on the next generation HERMES network stack, which hopefully will allow for worldwide deployment of the network. HERMES project provides a software stack (and hardware integration) for very-long distance telecommunication on HF band. Our focus currently are isolated communities (in terms of telecommunication access), especially in Amazon rain forest communities and Central Africa. Our current setup uses a proprietary P2P HF software-modem (called VARA) and UUCP on top of it, basically for email exchange, and ad-hoc file transfer and remote command execution. Our next-generation system will use an open-source modem (called Mercury) we are developing, together new upper network layers, which we are still evaluating (for eg., NNCP and Reticulum). We aim to expand the network world wide, for providing accessibility anywhere in the world through HF, and towards this goal, we'll carry this discussion / workshop for evaluation which would be the best options to take.

HERMES project provides a software stack (and hardware integration) for very-long distance telecommunication on HF band. Our focus currently are isolated communities (in terms of telecommunication access), especially in Amazon rain forest communities and Central Africa. Our current setup uses a proprietary P2P HF software-modem (called VARA) and UUCP on top of it, basically for email exchange, and ad-hoc file transfer and remote command execution. Our next-generation system will use an open-source modem (called Mercury) we are developing, together new upper network layers, which we are still evaluating (for eg., NNCP and Reticulum). We aim to expand the network world wide, for providing accessibility anywhere in the world through HF, and towards this goal, we'll carry this discussion / workshop for evaluation which would be the best options to take. We are taking a couple of radios (sBitx v3) for a full chain demonstration, and also a fully functional board (without the enclosure) to donate to anyone who wants to play with HF telecom. about this event: https://pretalx.sysmocom.de/osmodevcon2024/talk/BBZBGM/ </itunes:summary> <itunes:duration>01:01:47</itunes:duration> </item> <item> <title>JESD204B : Interfacing to modern ADC/DAC with LiteX (osmodevcon2024)</title> <link>https://media.ccc.de/v/osmodevcon2024-165-jesd204b-interfacing-to-modern-adc-dac-with-litex</link> <description>JESD204B is a pretty common interface to higher speed ADC/DAC used in software defined radio.

What does it mean to use 2.024 G data (aka EDGE 2.5G) in the year 2024? Our Osmocom 2G Data stack seems pretty mature at this point. Within the limits of the technology one can still use a remote ssh session, download email, do "instant messaging", including sending photos and short audio messages. All this works fine with one or two UE connected on a lab desk to a TRX configured for *high* capacity, However, introduce some TCH "stealing" the PDCH, some several 100's of UE (even just trying to attach) and some non optimal RF conditions and the capacity of the TRX is severely reduced. In these conditions, modern Android phones will saturate the TRX' capacity even with only their DNS lookups for "connectivity.google.com" - Maybe somewhat ironically? I've considered various steps to try to mitigate this situation. A common goto is to interfere with DNS, but this is disastrous. * In some cases, if Android cannot reach 8.8.8.8, regardless of what the network said to use for DNS, it will simply try again. - Of course, that can't be right. right? * If connectivity.google.com doesn't resolve, well that can't be right either, so try again. * If connectivity.google.com resolves, then HTTP GET /generate_204, and if this doesn't work, report to upper layer that there is no "Internet" and... you guessed it, try again. So we have to allow these things, which in itself is OK, as once the 204 is received, the phone will (probably) leave that alone, at least for a few minutes, but what comes next is all of what one might imagine is in the various phones, checks for system updates, app stores updates, uploading all the surveillance info that the google "services" cached while disconnected, and *who knows what else. *those running HTTP toolkit ;-) And that's before we even consider whatever is installed in "user space" (if such a thing can really be considered to exist on an Android device) starts. My current solution to this is to allow a limited amount of services, and then use netfilter's TARPIT module to get the phones to back off from everything else. Let's look a little a that, and maybe discuss what other optimizations could be done - For example netfilter scheduling and queues at the GGSN's IP interface. How about limiting the DL bandwidth per IP at this point? Give ACKs and short packets priority?

What does it mean to use 2.024 G data (aka EDGE 2.5G) in the year 2024? Our Osmocom 2G Data stack seems pretty mature at this point. Within the limits of the technology one can still use a remote ssh session, download email, do "instant messaging", including sending photos and short audio messages. All this works fine with one or two UE connected on a lab desk to a TRX configured for *high* capacity, However, introduce some TCH "stealing" the PDCH, some several 100's of UE (even just trying to attach) and some non optimal RF conditions and the capacity of the TRX is severely reduced. In these conditions, modern Android phones will saturate the TRX' capacity even with only their DNS lookups for "connectivity.google.com" - Maybe somewhat ironically? I've considered various steps to try to mitigate this situation. A common goto is to interfere with DNS, but this is disastrous. * In some cases, if Android cannot reach 8.8.8.8, regardless of what the network said to use for DNS, it will simply try again. - Of course, that can't be right. right? * If connectivity.google.com doesn't resolve, well that can't be right either, so try again. * If connectivity.google.com resolves, then HTTP GET /generate_204, and if this doesn't work, report to upper layer that there is no "Internet" and... you guessed it, try again. So we have to allow these things, which in itself is OK, as once the 204 is received, the phone will (probably) leave that alone, at least for a few minutes, but what comes next is all of what one might imagine is in the various phones, checks for system updates, app stores updates, uploading all the surveillance info that the google "services" cached while disconnected, and *who knows what else. *those running HTTP toolkit ;-) And that's before we even consider whatever is installed in "user space" (if such a thing can really be considered to exist on an Android device) starts. My current solution to this is to allow a limited amount of services, and then use netfilter's TARPIT module to get the phones to back off from everything else. Let's look a little a that, and maybe discuss what other optimizations could be done - For example netfilter scheduling and queues at the GGSN's IP interface. How about limiting the DL bandwidth per IP at this point? Give ACKs and short packets priority? We could limit the bandwidth here to the TRX capacity, but what if there is more than one SGSN, maybe an unknown number of SGSN (and TRX) connected at any one time?

Was ist das eigentlich, "Zivilcourage", was bedeutet sie, warum brauchen wir sie heute noch mehr als früher - und zwar offline und online? Das müssen wir in diesem Talk klären. Erst dann können wir uns Fragen widmen wie: Wie erkennt man, ob Menschen unsere Hilfe brauchen oder wir uns (unerwünscht) einmischen? Wie spricht man Opfer an, gerade bei Unsicherheit, ob sie Hilfe brauchen und wollen? Sollten wir das Einmischen lassen, wenn wir unsicher sind? [Spoiler: Nein.] Jede*r kann und sollte Zivilcourage zeigen, unabhängig von Alter, optischen und körperlichen Merkmalen, Herkunft ... aber sich niemals selbst in unkalkulierbare Gefahr begeben. Deshalb müssen wir darüber sprechen, wie wir Zivilcourage zeigen, aber Selbstschutz wahren, können. Und uns vergegenwärtigen, dass echter Einsatz nicht endet, wenn Polizei, Behören und Justiz übernommen haben, sondern dann (vielleicht) erst anfängt. Im dritten Teil des Talks müssen wir über für Opfer gefährliche Arten reden, nicht zu helfen. Nicht, weil gut gemeint oft nicht gut gemacht ist. Sondern, weil Zivilcourage auch heißt, sich im Namen der Opfer gegen untätige Behörden aufzulehnen, auf Täter-Opfer-Umkehr, Victim Blaming und sekundäre Viktimisierung aufmerksam zu machen. Und natürlich wird der Talk auf meine persönlichen Erfahrungen mit Zivilcourage eingehen.

Und was wir dabei gelernt und erfahren haben möchte ich euch nicht vorenthalten. about this event: https://cfp.gulas.ch/gpn22/talk/NAFLDR/ </itunes:summary> <itunes:duration>00:59:04</itunes:duration> </item> <item> <title>High-performance I/O using io_uring via osmo_io (osmodevcon2024)</title> <link>https://media.ccc.de/v/osmodevcon2024-209-high-performance-i-o-using-iouring-via-osmoio</link> <description>Traditional socket I/O via `read/write/recvfrom/sendto/recvmsg/sendmsg` and friends creates a very high system call load.

Zur Einstimmung präsentiere ich Ihnen alternative Realitäten des Gesundheitswesens und wie politische Fiktionen zu Fakten werden. Danach treffen diese politischen Fakten auf die Alltagsrealität.

Informationelle Erkrankung entsteht, wenn Information von außen auf die Betroffenen lebensverändernd einwirkt. Das hat es schon immer gegeben. Zusammen mit dem Wirkungsverlust von Fakten verlieren wir gerade die Wissenschaft als sozialen Moderationsraum. Muss man das alles zu einer Frage der Gesundheit machen? Nein, muss man nicht, aber wenn sich sonst keiner zuständig sieht, dann schon. Exklusion und Armut machen krank und dann sind wir Ärzte zuständig. Hier geht es um die Verhinderung von Krankheit und vorzeitigem Tod und da sind die Ärzte, als die akademischen Experten für Gesundheit und Krankheit unzweifelhaft gefragt. Gleichzeitig verlagert der Ansatz der bio-psycho-sozio-informationellen Erkrankung, oder kurz der informationellen Erkrankung, Teilaspekte von Krankheit, die heute allein einzelnen Menschen zugeordnet werden, zurück ins soziale System, so wie es die Ottawa-Charta der WHO fordert, um Gesundheit zu befördern.

Das Ziel der IT-Sicherheit ist nicht nur die Gewährleistung eines sicheren Laufzeitschutzes, sondern auch die Unterstützung der Teams bei der Definition und Erreichung von Sicherheitszielen. Daher benötigen wir einen kontinuierlichen IT-Sicherheitsansatz, der sich darauf konzentriert, den richtigen Stakeholdern zum richtigen Zeitpunkt das richtige Feedback zu geben. Wir werden uns ansehen, wie moderne Sicherheitsteams einen kontinuierlichen Sicherheitsansatz umsetzen, in die Entwicklung integrieren und bessere Ergebnisse als mit traditionellen Methoden erzielen.

This is a high effort shitpost: we woke up one day and chose violence — if in "violence" you include using bash for the things that really should use a systems programming language, that is. We implemented emulators, network servers, parsed text and binary data alike, and crafted libraries to help with all of the above – just so you don't have to wonder: "could it be done"? about this event: https://cfp.gulas.ch/gpn22/talk/TL97JJ/ </itunes:summary> <itunes:duration>01:00:41</itunes:duration> </item> <item> <title>osmo-epdg: The osmocom ePDG for VoWiFi (osmodevcon2024)</title> <link>https://media.ccc.de/v/osmodevcon2024-179-osmo-epdg-the-osmocom-epdg-for-vowifi</link> <description>After working on it on and off during 2023, we finally have a working ePDG in the Osmocom universe.

Wie läuft eine Demoparty ab? Und vor allem: Wie kann man da mitmachen? Eine Starthilfe für Neugierige, inklusive Tipps und Tools. Die Demoszene schafft seit 40 Jahren echtzeitgerenderte Computeranimationen am Rande des technisch Machbaren. Egal ob auf einem C64 oder in aktuellen Browsern.

Wie läuft eine Demoparty ab? Und vor allem: Wie kann man da mitmachen? Eine Starthilfe für Neugierige, inklusive Tipps und Tools. Die Demoszene schafft seit 40 Jahren echtzeitgerenderte Computeranimationen am Rande des technisch Machbaren. Egal ob auf einem C64 oder in aktuellen Browsern.

T1S mit Multidrop ermöglicht es einfache Interfaces, wie LIN, CAN, UART, etc. ins Netzwerk zu bekommen und das alles in einem einfachen Bussystem. Ebenso ein Überblick über die momentan herrschenden Standards und wie man das in vorhandene Projekte bekommt. Beim Besuch des diesjährigen Automotiv Ethernet Congress gab einen Einblick in jetzigen Standards, interessante Bauteile. Dies hat auch noch mal zur Änderungen beim WomoLIN Projekt geführt.

T1S mit Multidrop ermöglicht es einfache Interfaces, wie LIN, CAN, UART, etc. ins Netzwerk zu bekommen und das alles in einem einfachen Bussystem. Ebenso ein Überblick über die momentan herrschenden Standards und wie man das in vorhandene Projekte bekommt. Beim Besuch des diesjährigen Automotiv Ethernet Congress gab einen Einblick in jetzigen Standards, interessante Bauteile. Dies hat auch noch mal zur Änderungen beim WomoLIN Projekt geführt.

The stage is yours. You have 10 minutes to talk about anything. A short talk about the aerodynamics of ducks; promoting your new open-source project; a small hack that you found; social commentary ... anything goes. Available infrastructure: A microphone, beamer and laptop with a USB-Stick to show slides (PDF format). If you want to use your own device to show your presentation, please come to the stage 15 minutes before the event so we can test the setup. If you want to have a talk, we'd like you to write a short e-mail to pony@hadiko.de or just call DECT 7063 (P0N3). However, spontaneous contributions are also welcome if there's still some time left at the end. -- german -- Du willst was sagen? Das Podium gehört dir. 10 Minuten hast du, dann wird gewechselt. Ein kurzer Vortrag über die Aerodynamik von Enten, Werbung für dein neues Open-Source-Projekt, ein kleiner Hack den du neulich entdeckt hast, gesellschaftliche Kommentare ... alles geht. Zur Verfügung stehen Mikrophon, Beamer und ein Laptop mit USB-Stick, um Präsentationen im PDF-Format zu zeigen. Falls du eine Präsentation von deinem eigenen Gerät zeigen möchtest, würden wir dich bitten, 15 Minuten vor Beginn zu kommen, damit wir die Technik testen können.

If not handled carefully, Unrestricted File Uploads (UFUs) may appear and become a serious security issue. Our academic results show that some UFU types still fly under the state-of-the-art vulnerability scanners' radars, leaving websites at risk of severe vulnerabilities, such as Remote Code Execution or Cross-Site Scripting. Thus, we propose a File Upload Exploitation Lab (FUEL) to (em)power vulnerability scanners to become better at identifying UFUs and invite the community to reFUEL. If web applications fail to validate or handle user uploaded files properly, security issues such as Cross-Site Scripting or Remote Code Execution may arise. While PHP-based web applications are known to be prone to Unrestricted File Upload (UFU) vulnerabilities, other programming languages and web frameworks might be affected, too. Academic and non-academic work has covered many types of UFUs vulnerabilities and created vulnerability scanners to identify them. We have compared four different vulnerability scanners (BurpSuite, ZAP, FUSE and Fuxploider) with our novel File Upload Exploitation Lab (FUEL) to identify potential shortcomings in the detection capabilities. The results show that none of these state-of-the-art scanners manages to identify the UFU vulnerability in all of the 15 FUEL scenarios. Attendees of this talk will learn about UFUs and some less-known file upload bypasses. Further, we hope to raise the awareness that, similar to humans, no tool is perfect. Last but not least, we will invite the community to extend FUEL with more UFU scenarios to create a more thorough vulnerability scanner evaluation framework. The academic paper is to be published at DIMVA 2024, but we wanted to give the community a sneak preview :) about this event: https://cfp.gulas.ch/gpn22/talk/FSMH9M/ </description> <enclosure url="https://cdn.media.ccc.de/events/gpn/gpn22/h264-hd/gpn22-347-eng-Help_Us_Identify_UFUs_Em_Powering_Vulnerability_Scanners_with_FUEL_hd.mp4" length="291504128" type="video/mp4"/> <pubDate>Fri, 31 May 2024 10:00:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/gpn/gpn22/h264-hd/gpn22-347-eng-Help_Us_Identify_UFUs_Em_Powering_Vulnerability_Scanners_with_FUEL_hd.mp4?1717158902</guid> <dc:identifier>3bb7e2fa-efe9-5cbe-8e50-f0e355cb46b7</dc:identifier> <dc:date>2024-05-31T10:00:00+02:00</dc:date> <itunes:author>Sebastian Neef aka gehaxelt, Moaath</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>gpn22, 347, 2024, Software & Infrastructure</itunes:keywords> <itunes:summary>Nowadays, many websites rely on user-generated content, e.g., by allowing users to upload images, videos, documents, or other files.

We have compared four different vulnerability scanners (BurpSuite, ZAP, FUSE and Fuxploider) with our novel File Upload Exploitation Lab (FUEL) to identify potential shortcomings in the detection capabilities. The results show that none of these state-of-the-art scanners manages to identify the UFU vulnerability in all of the 15 FUEL scenarios. Attendees of this talk will learn about UFUs and some less-known file upload bypasses. Further, we hope to raise the awareness that, similar to humans, no tool is perfect. Last but not least, we will invite the community to extend FUEL with more UFU scenarios to create a more thorough vulnerability scanner evaluation framework. The academic paper is to be published at DIMVA 2024, but we wanted to give the community a sneak preview :) about this event: https://cfp.gulas.ch/gpn22/talk/FSMH9M/ </itunes:summary> <itunes:duration>00:19:51</itunes:duration> </item> <item> <title>RP Pico: Simple Stupid Synth (gpn22)</title> <link>https://media.ccc.de/v/gpn22-496-rp-pico-simple-stupid-synth</link> <description>Mit einem einzelnen µ-Controller lässt sich kein 32-stimmig polyphoner Synthesizer bauen?

This talk will give an introduction into the topic: Why might governments, associations or political parties turn to internet voting? What are the security requirements of such a system, and how does this differ to e-banking or postal voting? How do such systems work, and what separates a bad from a good (or at least a "better") voting system? Everything is better digitalized: e-banking, crypto currencies, smart homes, vtubers, ... - so when can we finally vote online? /s When a government, and an association or a political party starts to provide internet voting to its voters, it usually aims to increase turnout or reduce cost, while retaining a similar level of security than their current voting methods. But the security of internet voting is hard to compare to the security of other voting channels or other secure systems, such as e-banking. Further, reduced cost or increased turnout depends heavily on the context the election is held in. But what if the decision is taken, that internet voting needs to be provided? Simple systems usually do not cut it, as they need to relay on strong trust assumptions in the system provider, the administrators and even the voters. Against rogue employees or even nation-state adversaries, a black-box system stands no chance. Even in strong adversarial scenarios needs the system to keep votes secret, but at the same time remain transparent to verify the votes have been tallied correctly. Internet voting systems are in active use for political elections, for example in Switzerland. Looking at the history of such systems shows how full transparency and independent evaluations are necessary to detect flaws. For non-political elections (e.g. universities, associations), few available systems are sufficiently transparent to even begin evaluating them, and certifications such as BSI's corresponding Common Criteria are insufficient on their own. To summarize, the talk answers the following questions: - Why institutions would want or not want to use internet voting. - What properties an (internet) voting systems need to achieve. - What separates a bad from a better internet voting system.

The stage is yours. You have 10 minutes to talk about anything. A short talk about the aerodynamics of ducks; promoting your new open-source project; a small hack that you found; social commentary ... anything goes. Available infrastructure: A microphone, beamer and laptop with a USB-Stick to show slides (PDF format). If you want to use your own device to show your presentation, please come to the stage 15 minutes before the event so we can test the setup. If you want to have a talk, we'd like you to write a short e-mail to pony@hadiko.de or just call DECT 7063 (P0N3). However, spontaneous contributions are also welcome if there's still some time left at the end. -- german -- Du willst was sagen? Das Podium gehört dir. 10 Minuten hast du, dann wird gewechselt. Ein kurzer Vortrag über die Aerodynamik von Enten, Werbung für dein neues Open-Source-Projekt, ein kleiner Hack den du neulich entdeckt hast, gesellschaftliche Kommentare ... alles geht. Zur Verfügung stehen Mikrophon, Beamer und ein Laptop mit USB-Stick, um Präsentationen im PDF-Format zu zeigen. Falls du eine Präsentation von deinem eigenen Gerät zeigen möchtest, würden wir dich bitten, 15 Minuten vor Beginn zu kommen, damit wir die Technik testen können.

Was wäre aber, wenn man die alte Hardware nachbilden könnte? Ich zeige, wie man mit sogenannten FPGAs fast vergessene Technik auch ohne Lötkolben daheim nachbaut und so alten Spielen neues Leben einhaucht. FPGAs (Field Programmable Gate Arrays) sind eine eigene Chip-Familie. Anders als z.B. klassische Prozessoren oder Speicherchips erfüllen FPGAs ab Werk keine spezielle Funktion. Erst durch passende Konfiguration erfährt das FPGA, was es eigentlich darstellen soll. Normalerweise setzt man sie ein, wenn es um selten benötigte und spezielle Funktionen geht, die Halbleiter von der Stange nicht bieten und für die die Entwicklung eines eigenen Halbleiters zu teuer und/oder zu aufwändig wäre. Wir nutzen FPGAs, um Chips nachzubilden, die nicht mehr hergestellt werden. Dabei machen wir uns zu Nutze, dass moderne FPGAs komplette Geräte der Homecomputer-Ära in einem einzige Chip unterbringen können. Mit dem MiST habe ich vor über 10 Jahren eines der ersten Geräte dieser Art entwickelt und auf den Markt gebracht. Seitdem ist die Zeit nicht stehen geblieben und mit dem Nachfolger MiSTer ist FPGA-Retrogaming endgültig in der Breite angekommen. Das hat wiederum weitere Entwickler auf den Plan gerufen, sodass inzwischen alle wichtigen Computer und Konsolen der 80er und viele der 90er auf FPGAs umgesetzt wurden. Ich werde erklären, wie sich FPGA-Nachbildungen von Emulatoren unterscheiden und was ein FPGA besser als eine Emulation auf Software-Basis z.B. auf einem PC macht und wo die Nutzung von FPGAs an ihre Grenzen stößt. Neben immer größeren FPGAs, die die Umsetzung immer jüngerer Maschinen ermöglichen, sind auch die Entwicklungen in Fernost im Billigbereich interessant und die Geräte auf denen man FPGA-Projekte aufbauen kann, werden immer erschwinglicher und kleiner. Wie FPGA-Retrogaming funktioniert, wie man damit auch daheim mit kleinem Budget in die Entwicklung integrierter (Retro-)Schaltungen einsteigen kann und wo FPGA-Retrogaming heute steht, werde ich im Detail beleuchten. about this event: https://cfp.gulas.ch/gpn22/talk/HVH9HE/ </description> <enclosure url="https://cdn.media.ccc.de/events/gpn/gpn22/h264-hd/gpn22-272-deu-Retrogaming_mit_FPGAs_hd.mp4" length="486539264" type="video/mp4"/> <pubDate>Fri, 31 May 2024 18:45:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/gpn/gpn22/h264-hd/gpn22-272-deu-Retrogaming_mit_FPGAs_hd.mp4?1717188285</guid> <dc:identifier>7669ced2-5cdb-566e-bab9-984afa774e3b</dc:identifier> <dc:date>2024-05-31T18:45:00+02:00</dc:date> <itunes:author>Till Harbaum</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>gpn22, 272, 2024, Games</itunes:keywords> <itunes:summary>Um mit Retro-Spielen Spaß zu haben, braucht man entweder die alte Originalhardware oder man greift zu PC und Emulatorsoftware.

In Zeiten des Online-Shoppings sind die Menschen besorgt, ob Online-Shops ihre Daten vernünftig behandeln und sichern. Online-Shops können über gängige Web-Schwachstellen wie SQL-Injections, XSS usw. angegriffen werden. Dadurch könnten Angreifer persönliche Informationen wie Name, Adresse und Bankdaten kopieren. Wir haben jedoch eine noch einfachere - und bisher unbeachtete - Möglichkeit gefunden, an die persönlichen Daten der Kunden von Online-Shops zu gelangen - ohne irgendwelche Schwachstellen auszunutzen. Da fast alle online bestellten physischen Waren von Paketdiensten ausgeliefert werden, haben wir das Tracking der wichtigsten Akteure im deutschen Paketmarkt analysiert. Durch die Verwendung öffentlich zugänglicher Daten und trivialer Statistik konnten wir Empfängerinformationen (Name, Adresse) schnell und in großer Zahl ermitteln. Dabei war es bei einigen Diensten sogar möglich, die Zustellung von Paketen zu beeinflussen. Gezielte Angriffe könnten dazu führen, dass Adressen und Einkaufsverhalten von Politikern und anderen Personen des öffentlichen Lebens aufgedeckt werden. Auch die Identifizierung von Kunden bestimmter Geschäfte ist denkbar. Die Art und Weise, wie die Sendungsnummern generiert werden, ermöglicht es uns nämlich, gezielt bestimmte Online-Shops anzugreifen. Während unserer Recherche haben wir mehrere Paketdienste kontaktiert (Responsible Disclosure), was zu einigen Verbesserungen führte. Einige Disclosure-Prozesse hatten schnelle und effektive Maßnahmen zur Folge und können als gute Beispiele dienen, während andere noch Raum für Optimierungen bieten. Wir werden auch darüber reden, wie Disclosure-Prozesse besser ablaufen können, und werden ein paar unterhaltsame Ereignisse darstellen. Wir kommen zu dem Schluss, dass Paketdienste eine - vielleicht - unterschätzte Gefahr für die Privatsphäre darstellen. Anstatt zahllose Online-Shops anzugreifen, ist der Missbrauch fehlerhafter Prozesse bei den wenigen marktbeherrschenden Paketzustelldiensten, die von fast allen Shops genutzt werden, ein ziemlich effizienter Weg, um an Adressen und in einigen Fällen an die Möglichkeit zu gelangen, in den Zustellprozess einzugreifen. In unserem Vortrag werden wir den statistischen Ansatz zum Brechen der Authentifizierung für die Paketverfolgung, die zugrundeliegenden Probleme, (negative und positive) Highlights aus den Disclosure-Prozessen und natürlich die Auswirkungen auf die Privatsphäre aufzeigen, die dies gehabt haben könnte und noch haben kann. Bei der diesjährigen GPN sprechen wir zum ersten Mal über zwei Paketdienstleister, die bei uns bisher noch nicht zur Sprache kamen, GLS und UPS. Zum Zeitpunkt der Veröffentlichung war die Schwachstelle bei UPS noch nicht behoben. about this event: https://cfp.gulas.ch/gpn22/talk/ABDM9K/ </description> <enclosure url="https://cdn.media.ccc.de/events/gpn/gpn22/h264-hd/gpn22-266-deu-Down_the_Parcel_Hole_hd.mp4" length="833617920" type="video/mp4"/> <pubDate>Thu, 30 May 2024 21:00:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/gpn/gpn22/h264-hd/gpn22-266-deu-Down_the_Parcel_Hole_hd.mp4?1717148326</guid> <dc:identifier>80078888-2260-5cb2-85fd-b538a2db9f51</dc:identifier> <dc:date>2024-05-30T21:00:00+02:00</dc:date> <itunes:author>Dennis Kniel, Florian Bausch</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>gpn22, 266, 2024, Security</itunes:keywords> <itunes:summary>Dieser Vortrag beschreibt, wie wir fehlerhafte Prozesse in der Paketverfolgung der meisten deutschen Paketzustelldienste entdeckt haben, wie diese auf unsere Erkenntnisse reagiert haben und warum dies sehr wahrscheinlich auch deine Privatsphäre betrifft.

Im Vortrag möchte ich Möglichkeiten zeigen wie es trotz unterschiedlicher Regelung möglich ist cool Bilder zu machen und die Stimmung bestmöglich einzufangen. Fotografieren auf Chaos Events ist eine Herausforderung. Veranstaltungen wie das Camp oder der Congress haben eine eher restriktive Foto-Policy, die GPN dagegen hat eine eher liberale Version, die ein anderes Herangehen und damit andere Bilder ermöglicht. Mit meinem Vortrag möchte ich die Diskussion darüber weiterführen, wie ein für alle akzeptabler Umgang mit den verschiedenen Policies möglich ist und wie trotzdem kreative Bilder entstehen können, die die Stimmung bestmöglich einfangen, ohne den sozialen Frieden zu gefährden. Dazu möchte ich auch die Ergebnisse meiner Umfrage nach dem letzten Congress vorstellen, in der mehr als 1000 Menschen ihre Meinung zur Photopolicy geteilt haben. about this event: https://cfp.gulas.ch/gpn22/talk/J7XBBK/ </description> <enclosure url="https://cdn.media.ccc.de/events/gpn/gpn22/h264-hd/gpn22-460-deu-Fotografieren_auf_Chaos_Events_hd.mp4" length="839909376" type="video/mp4"/> <pubDate>Fri, 31 May 2024 20:00:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/gpn/gpn22/h264-hd/gpn22-460-deu-Fotografieren_auf_Chaos_Events_hd.mp4?1717189137</guid> <dc:identifier>c7526757-9937-5b7b-8ec8-99011a805d6a</dc:identifier> <dc:date>2024-05-31T20:00:00+02:00</dc:date> <itunes:author>Leah</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>gpn22, 460, 2024, Art & Culture</itunes:keywords> <itunes:summary>Fotografieren auf Chaos Events ist eine Herausforderung.

Veranstaltungen wie das Camp oder der Congress haben eine eher restriktive Foto-Policy, die GPN dagegen hat eine eher liberale Version, die ein anderes Herangehen und damit andere Bilder ermöglicht. Mit meinem Vortrag möchte ich die Diskussion darüber weiterführen, wie ein für alle akzeptabler Umgang mit den verschiedenen Policies möglich ist und wie trotzdem kreative Bilder entstehen können, die die Stimmung bestmöglich einfangen, ohne den sozialen Frieden zu gefährden. Dazu möchte ich auch die Ergebnisse meiner Umfrage nach dem letzten Congress vorstellen, in der mehr als 1000 Menschen ihre Meinung zur Photopolicy geteilt haben. about this event: https://cfp.gulas.ch/gpn22/talk/J7XBBK/ </itunes:summary> <itunes:duration>00:59:14</itunes:duration> </item> <item> <title>Passkeys – Login ohne Passwort (?)

The more knowledge we can make the compiler aware of, the more we can rely on the compiler. But what is the limit? What if we could take _make bad state unrepresentable_ to the mathematical extreme? What is a proof anyway, can you eat it? Come on a wonderful journey into the land of dependent types, where we try building type-safe SQL queries, and sweeten the deal with our own syntactic sugar. I give a compressed intro and overview of Lean 4, a purely functional, dependently typed programming language and interactive theorem prover. Knowledge of purely functional languages is *not* required. 1. We start from zero. Introduction to Lean 4 syntax, side-by-side with Rust. Sum and product types, `List`, some easy intro examples. 2. _Dependent types_: Example of `Vec`, i.e. lists with statically known length. Dependent pattern matching. 3. _Propositions-as-types_: You can have logical `And` and `Or` in Rust, too! But how do you model forall quantifiers? How do you model `x <= y` in the type system? 4. Playing around with _types as first-class objects_, using heterogenous lists and projections on them as example. You can't pattern match on types themselves, or... can you? 5. _Metaprogramming_: Custom syntax, custom elaborators.

Stalking ist eine Form von Gewalt, bei der betroffene Personen verfolgt oder bedroht werden. Das kann auch über Internet und andere digitalen Medien stattfinden. Diese Formen werden Cyberstalking genannt. In dem Vortrag werden die technischen Aspekte von Fällen erklärt, bei der Betroffene in ihrer Aktivität am Smartphone verfolgt und manipuliert werden oder auch ihr Standort durch einen Angreifer überwacht wird. Dies wird möglich durch das Teilen von Zugangsdaten und auch durch den Einsatz von sogenannter Stalkerware. Wie diese Verfahren funktionieren und wie der Schutz dagegen effektiv sein kann, werdet ihr bei dem Vortrag erfahren. Unsere Referent*in wifi-cable ist Informatikerin und engagiert sich im Team Antistalking.

Stalking ist eine Form von Gewalt, bei der betroffene Personen verfolgt oder bedroht werden. Das kann auch über Internet und andere digitalen Medien stattfinden. Diese Formen werden Cyberstalking genannt. In dem Vortrag werden die technischen Aspekte von Fällen erklärt, bei der Betroffene in ihrer Aktivität am Smartphone verfolgt und manipuliert werden oder auch ihr Standort durch einen Angreifer überwacht wird. Dies wird möglich durch das Teilen von Zugangsdaten und auch durch den Einsatz von sogenannter Stalkerware. Wie diese Verfahren funktionieren und wie der Schutz dagegen effektiv sein kann, werdet ihr bei dem Vortrag erfahren. Unsere Referent*in wifi-cable ist Informatikerin und engagiert sich im Team Antistalking.

Auch computergenerierte Bilder sind immer schwieriger von echten zu unterscheiden. Dies verändert die Art und Weise, wie wir Medien konsumieren – und es verändert die Arbeit von Medienschaffenden. Aber was bedeutet das? Braucht es in Zukunft gar keinen Journalismus mehr, weil eine KI die Zeitung schreibt? Oder braucht es diesen nun erst recht? Und wie können Medienschaffende diese neuen Werkzeuge nutzen und uns besseren Journalismus bieten? Diese Fragen diskutieren wir mit Timo Grossenbacher.

Functional programming langaunges like Haskell offer a unique approach to achieving these goals through strong type systems, immutable data structures, and pure functions. Despite its practical benefits, functional programming is not yet widely-used in mainstream development. Here, we'll take you on a gentle exploration of the fundamentals of functional programming, emphasizing concepts like referential transparency, purity, and correctness through verifiable specifications. Through practical examples and approachable explanations, we will illustrate how Haskell's paradigms can lead to a more robust and maintainable codebase. This talk serves as a friendly guide for beginners eager to dive into the world of functional programming and to harness its power to write verifiably correct, maintainable software. about this event: https://cfp.ctbk.de/fsck-2024/talk/E77ZQY/ </description> <enclosure url="https://cdn.media.ccc.de/events/fsck/fsck2024/h264-hd/fsck2024-57-deu-Functional_correctness_--_Haskell-ing_your_way_to_reliable_code_hd.mp4" length="278921216" type="video/mp4"/> <pubDate>Fri, 03 May 2024 18:00:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/fsck/fsck2024/h264-hd/fsck2024-57-deu-Functional_correctness_--_Haskell-ing_your_way_to_reliable_code_hd.mp4?1715890654</guid> <dc:identifier>987fc8f3-a4b7-5d0e-b782-71100c143910</dc:identifier> <dc:date>2024-05-03T18:00:00+02:00</dc:date> <itunes:author>yote</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>fsck2024, 57, 2024, Hard- & Software, fsck2024</itunes:keywords> <itunes:summary>In the realm of modern software development, ensuring correctness and reliability of software systems is paramount. Functional programming langaunges like Haskell offer a unique approach to achieving these goals through strong type systems, immutable data structures, and pure functions. Despite its practical benefits, functional programming is not yet widely-used in mainstream development. Here, we'll take you on a gentle exploration of the fundamentals of functional programming, emphasizing concepts like referential transparency, purity, and correctness through verifiable specifications.

Sie erstellt Kunstwerke und räumt Preise ab, sie generiert Texte, Bilder, ganze Bücher. Tech-Begeisterte jubilieren und preisen den demokratisierenden Aspekt der Technologie.

Is that only due to how the browser works or is it also our fault as web apps developers? In fact, modern JS apps are becoming increasingly complicated, so their compute and memory requirements are rising as well, with some famous websites even taking up entire gigabytes of memory. This does not only fill up the memory of your users devices, but can also cause crashes and performance drops. How do we monitor if that's the case, and how can we fix it? This talk will shed some light on the dark art of memory allocations and profiling, showing how some data structures and some JS frameworks are less efficient than others.

Gestaltet und entwickelt nach den Bedürfnissen von freien Radiosendern in Österreich und Deutschland, bietet AURA mit seiner modularen Architektur ein "Komplettlösung" für den Radiobetrieb. Das Projekt verwirklicht zudem das Prinzip "Community by Design" - Radiomacher:innen dürfen die Software von Anfang an testen und mitgestalten. Im Talk erfahrt ihr etwas über das Projekt, seine Architektur und erlebt AURA in einer hands-on Demo in Aktion. Wolltest Du schon immer selbst "on air" gehen und Dein eigenes Radioprogramm gestalten? Freie Sender stehen vor der Herausforderung, dass Softwarelösungen für Radio-Programmverwaltung und -automation rar und teuer sind. Das Projekt AURA setzt ein Zeichen, dass es auch anders geht: AURA ist eine Open Source-Softwaresuite, die von Mitgliedern der freien Radios aus Graz, Linz, Wien, Innsbruck u.A. entwickelt wird. Nach dem „Baukastenprinzip“ können Funktionsmodule wie Playout, Aufnahme, Scheduling, Medienverwaltung, etc. kombiniert werden. Eine moderne und nutzer:innenfreundliche Weboberfläche macht die Programmverwaltung für die ganze Redaktion auch von zu Hause aus möglich.

Gestaltet und entwickelt nach den Bedürfnissen von freien Radiosendern in Österreich und Deutschland, bietet AURA mit seiner modularen Architektur ein "Komplettlösung" für den Radiobetrieb. Das Projekt verwirklicht zudem das Prinzip "Community by Design" - Radiomacher:innen dürfen die Software von Anfang an testen und mitgestalten. Im Talk erfahrt ihr etwas über das Projekt, seine Architektur und erlebt AURA in einer hands-on Demo in Aktion. Wolltest Du schon immer selbst "on air" gehen und Dein eigenes Radioprogramm gestalten? Freie Sender stehen vor der Herausforderung, dass Softwarelösungen für Radio-Programmverwaltung und -automation rar und teuer sind. Das Projekt AURA setzt ein Zeichen, dass es auch anders geht: AURA ist eine Open Source-Softwaresuite, die von Mitgliedern der freien Radios aus Graz, Linz, Wien, Innsbruck u.A. entwickelt wird. Nach dem „Baukastenprinzip“ können Funktionsmodule wie Playout, Aufnahme, Scheduling, Medienverwaltung, etc. kombiniert werden. Eine moderne und nutzer:innenfreundliche Weboberfläche macht die Programmverwaltung für die ganze Redaktion auch von zu Hause aus möglich. UX und Design von AURA werden in engem Austausch mit der Radio-Community entworfen und verbessert. Mitglieder vom Aura-Team stellen das Projekt und seine Architektur vor. Anhand einer Kurz-Demo kann man AURA in Aktion sehen. Außerdem wird gezeigt, wie das Prinzip „Community by design“ im Aura-Projekt in der Planung und Gestaltung verwirklicht wird.

It leverages the power of web workers, WebAssembly, and a combination of optimisation techniques to run a Git visualisation locally in the web browser. The talk will look at some of the technical challenges which were overcome, including strategies to minimise memory footprint, implement performant file operations, and distribute workload using web workers. This talk presents Gizual, a cutting-edge open-source web application, which reimagines Git code repository visualisation and interaction in the spirit of SeeSoft [1]. The Gizual user interface uses a zoomable timeline component for detailed navigation through the commit history of a repository. A zoomable visual overview is then provided for a specified (sub)set of files for the chosen commit, which is colour-coded by metrics such as age of line of code, or author of line of code. Pre-generated preview images and a pool of web workers are used for enhanced performance. Overview statistics such as contribution charts are also provided. Beneath the user interface, Gizual exploits the bleeding edge of WebAssembly (WASM) to run performant Git operations directly in the browser. The WebAssembly System Interface (WASI) [2] is used to run libgit2 [3], together with various custom implementations for efficient file i/o and git index parsing. The talk will cover Gizual's innovative approaches to interaction and visualisation, and some of the technical challenges which were overcome, including strategies to minimise memory footprint, implement performant file operations, and distribute workload using web workers. It will conclude with a look at ongoing and potential future work.

One might wonder whether all problems are solved because most software developer resort to “Markdown” when user-provided texts are written these days. But are they? At least once you discover the differences between Markdown dialects, you wonder whether Markdown is really a good choice. In my investigations, I started with the simple question how to build a simple markup language parser. It turns out the simplicity in the parser is orthogonal to user friendliness. Simultaneously, I recognized how escaping mechanisms can - indeed - be designed simple and memorable. And they are too often forgotten. When I continued with the parsing topic, I recognized that markup languages do not at all serve the same purpose and need to be categorized. But this seems nontrivial. What is a “lightweight” markup language? What is a “document” markup language? And how can the simplicity of syntax be measured? What makes “XML” extensible? And what limits the adoption of markup languages besides Markdown? In this talk, I want to revisit how SGML turned into XML, remember the good old bbcodes of board software from the 2000s, how Wiki syntaxes were popularized and vanished, and Github made Markdown a big player. Afterwards I will present my findings and propose how to solve related questions. about this event: https://pretalx.linuxtage.at/glt24/talk/G7ALGR/ </description> <enclosure url="https://cdn.media.ccc.de/events/glt24/h264-hd/glt24-475-eng-Markup_languages_contemplated_categorized_and_criticized_hd.mp4" length="101711872" type="video/mp4"/> <pubDate>Sat, 06 Apr 2024 11:00:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/glt24/h264-hd/glt24-475-eng-Markup_languages_contemplated_categorized_and_criticized_hd.mp4?1712406118</guid> <dc:identifier>2b73cea3-5921-50ce-844a-459d929e28cf</dc:identifier> <dc:date>2024-04-06T11:00:00+02:00</dc:date> <itunes:author>tajpulo</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>glt24, 475, 2024, Anwendung</itunes:keywords> <itunes:summary>As part of my FOSS project in digital typesetting, I am interested in the depths of markup languages.

Um ein Videokonferenzsystem auf Basis der Open-Source-Software [OpenTalk](https://opentalk.eu/) zur Verfügung zu stellen, werden verschiedene Komponenten verwendet, die häufig in Containern laufen: - Die "Kernkomponente" [*OpenTalk Controller*](https://gitlab.opencode.de/opentalk/controller) (eine oder mehrere Instanzen davon) - Das [*OpenTalk Web-Frontend*](https://gitlab.opencode.de/opentalk/web-frontend) - [Janus](https://janus.conf.meetecho.com/) als WebRTC-Service - [PostgreSQL](https://www.postgresql.org/)-Datenbankservice - [RabbitMQ](https://www.rabbitmq.com/) zum Austausch von Nachrichten zwischen den Komponenten - [Redis](https://redis.io/) zur Speicherung der laufenden Videokonferenzen - OIDC-Provider, meist [Keycloak](https://www.keycloak.org/) - [*OpenTalk SMTP-Mailer*](https://gitlab.opencode.de/opentalk/smtp-mailer) zum Versand von Einladungs-Mails - [*OpenTalk Obelisk*](https://gitlab.opencode.de/opentalk/obelisk) als Dial-In-Service - [*OpenTalk Recorder*](https://gitlab.opencode.de/opentalk/recorder) zum Aufnehmen oder Streamen von Videokonferenzen Für die eigenen Komponenten waren bereits in weiten Teilen Unit-Tests vorhanden, die von der CI ausgeführt werden. Integrationstests, welche das Backend auf die korrekte Abarbeitung von Web-Requests und Websocket-Verbindungen in verschiedenen Szenarien prüfen, fehlten jedoch weitgehend.

Building upon the foundation laid by last year's introduction to NixOS and the Nix ecosystem, this talk takes participants on a journey from a fully declarative disk setup to the configuration of a wide range of services suitable for Linux server and homelab enthusiasts. Emphasizing reproducibility and ease of configuration, this session should appeal to NixOS users and homelab enthusiasts running other Linux distributions. Have you ever wanted to have complete control over your personal home server or homelab? Are you tired of manually configuring and maintaining your server, only to encounter unexpected issues down the line? Look no further! In this Linux conference talk, we will take another look at NixOS (a Linux distribution doing things different) and explore the benefits of a fully declarative approach to setting up your own server. Building upon the foundations laid in last year's talk that served as an introduction to NixOS and the Nix ecosystem, we will dive deeper into the possibilities that await you. Our focus will be on achieving reproducibility in your server setup, ensuring that you can confidently recreate your environment on-demand, without any surprises. We will begin by guiding you through a declarative disk setup and will then venture into the exciting realm of service configuration. Whether you have a particular interest in containerized services or prefer traditional setups, we've got you covered. Our talk will provide plenty of configuration examples, showcasing various services that you could run on your home server or homelab. Join us as we unravel the power and simplicity of NixOS. Discover how a fully declarative approach can revolutionize the way you set up and maintain your personal home server or homelab. Whether you're a seasoned Linux enthusiast or new to the world of server administration, this talk will equip you with the knowledge and tools to take control of your server infrastructure and create a reproducible, reliable, and personalized server environment. about this event: https://pretalx.linuxtage.at/glt24/talk/T37KQQ/ </description> <enclosure url="https://cdn.media.ccc.de/events/glt24/h264-hd/glt24-478-eng-Fully_declarative_Homelab_on_NixOS_hd.mp4" length="220200960" type="video/mp4"/> <pubDate>Sat, 06 Apr 2024 11:35:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/glt24/h264-hd/glt24-478-eng-Fully_declarative_Homelab_on_NixOS_hd.mp4?1712409467</guid> <dc:identifier>8432ea3f-662b-5087-91da-b46af48cc661</dc:identifier> <dc:date>2024-04-06T11:35:00+02:00</dc:date> <itunes:author>Matthias Thym</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>glt24, 478, 2024, Anwendung</itunes:keywords> <itunes:summary>In this talk, we'll explore the intricacies of setting up a reproducible personal home server or homelab using a fully declarative approach on NixOS.

Großer Beliebtheit erfreute und erfreut sich *PyEphem* (siehe [GLT2016](https://glt.foehnwall.at/glt16.html#pyephem-sonne-mond-und-sterne-in-python)), welches einen Python-Wrapper für eine inzwischen in die Jahre gekommen C-Bibliothek darstellt und für die Entwickler entsprechend umständlich zu warten ist. Vom Betreuer dieses Projektes, Brandon Rhodes, wurde mit **Skyfield** eine vollständige Neuentwicklung unternommen. Skyfield ist in **reinem Python** geschrieben und hat als einzige binäre Abhängigkeit **NumPy**, die bekannte numerische Bibliothek für wissenschaftliches Rechnen, welche mit schnellen Vektoroperationen die Effizienz von Skyfield garantiert. Der Anspruch von Skyfield ist es, sich den vom *United States Naval Observatory* im *Astronomical Almanac* publizierten Werten mit einer Genauigkeit von 0.5 Tausendstel(!) Bogensekunden anzunähern. Der Vortrag bringt zunächst einige für das Verständnis wichtige Vorbemerkungen zu Koordinaten- und Zeitsystemen.

Ich beobachte Häufig, insbesondere in Unternehmen, das viele bemüht sind ihren Elektroschrott los zu werden und froh sind wenn sie dafür am Wertstoffhof nichts dafür bezahlen müssen. Ich Zerlege stattdessen den Elektroschrott sortenrein und fahre das zum Schrotthändler und bekomme dort Geld dafür weil es halt Rohstoffe und kein Sondermüll ist.

Ich beobachte Häufig, insbesondere in Unternehmen, das viele bemüht sind ihren Elektroschrott los zu werden und froh sind wenn sie dafür am Wertstoffhof nichts dafür bezahlen müssen. Ich Zerlege stattdessen den Elektroschrott sortenrein und fahre das zum Schrotthändler und bekomme dort Geld dafür weil es halt Rohstoffe und kein Sondermüll ist.

In diesem Vortrag werdet ihr sanft in die Welt der SIMD-Programmierung eingeführt, und ihr lernt, wie man SIMD-Techniken für die effiziente Ausführung von Aufgabenstellungen aus der Textverarbeitung nutzen kann. about this event: https://fahrplan.eh21.easterhegg.eu/eh/talk/MHHYLZ/ </itunes:summary> <itunes:duration>00:44:34</itunes:duration> </item> <item> <title>Lightning Talks (eh21)</title> <link>https://media.ccc.de/v/eh21-139-lightning-talks</link> <description>Selbstorganisierte Lightningtalks in 5 Minuten Segmenten. about this event: https://fahrplan.eh21.easterhegg.eu/eh/talk/TVJML8/ </description> <enclosure url="https://cdn.media.ccc.de/events/eh2024/h264-hd/eh21-139-deu-Lightning_Talks_hd.mp4" length="943718400" type="video/mp4"/> <pubDate>Sun, 31 Mar 2024 16:00:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/eh2024/h264-hd/eh21-139-deu-Lightning_Talks_hd.mp4?1711921386</guid> <dc:identifier>c347a607-02af-5459-b88a-df2b1daad118</dc:identifier> <dc:date>2024-03-31T16:00:00+02:00</dc:date> <itunes:explicit>No</itunes:explicit> <itunes:keywords>eh21, 139, 2024</itunes:keywords> <itunes:summary>Selbstorganisierte Lightningtalks in 5 Minuten Segmenten. about this event: https://fahrplan.eh21.easterhegg.eu/eh/talk/TVJML8/ </itunes:summary> <itunes:duration>00:59:32</itunes:duration> </item> <item> <title>How to bike to Camp - Solo quer durch Deutschland (eh21)</title> <link>https://media.ccc.de/v/eh21-128-how-to-bike-to-camp-solo-quer-durch-deutschland</link> <description>Eine kurze Einführung ins Camp-Radeln. Wie man als Normal-Nerd bei Regen allein zum Camp radelt, was das mit einem macht und warum man das vielleicht ausprobieren möchte. Im Sommer bin ich solo 600 km in 5 Tagen quer durch Deutschland zum Camp gefahren und habe dazu auf Mastodon getrötet. Auch wenn das Wetter grösstenteils nass bis stürmisch und gewittrig war, war das ein sehr erfüllendes Erlebnis, das mir ein ganz neues Gefühl von Weite, Zeit und Freiheit gegeben hat. Aber mir auch viel über unser Land und seine Gemeinsamkeiten und Unterschiede gelehrt hat. Anschliessend habe ich viele Fragen bekommen: - Wie organisiert und plant man so eine Tour? Was braucht man dafür? - Wie oft fährst du sonst Rad bzw wie fit muss man sein um das zu können? - Wie weit kommt man pro Tag? Wie plant man eine Strecke? Was ist mit Wetter? Wie Übernachten? - Wie funktioniert so eine lange Tour psychisch? - Was ist der Plan, wenn man nicht mehr kann? Bei Pannen? Wenn es zu viel wird? - Wie viel futtert man eigentlich wenn man tagelang nur Fahrrad fährt? - Machst du das nochmal? Und: - Kannst du dazu einen Talk geben, wie man als Normal-Mensch mit einem Normal-Fahrrad das macht? Frisch zum kommenden Frühling würde ich daher gerne darüber erzählen, wie man auch bei Regen und Wind Spass mit dem Gerät Fahrrad haben kann, ohne Extremsportler zu sein. Und anderen Mut und Hilfe geben, so etwas auch einmal zu probieren. about this event: https://fahrplan.eh21.easterhegg.eu/eh/talk/78EWET/ </description> <enclosure url="https://cdn.media.ccc.de/events/eh2024/h264-hd/eh21-128-deu-How_to_bike_to_Camp_-_Solo_quer_durch_Deutschland_hd.mp4" length="734003200" type="video/mp4"/> <pubDate>Sun, 31 Mar 2024 11:00:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/eh2024/h264-hd/eh21-128-deu-How_to_bike_to_Camp_-_Solo_quer_durch_Deutschland_hd.mp4?1711893398</guid> <dc:identifier>e4ad1ffb-2eec-5db0-a1e6-37210fbe99e0</dc:identifier> <dc:date>2024-03-31T11:00:00+02:00</dc:date> <itunes:author>katzazi</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>eh21, 128, 2024</itunes:keywords> <itunes:summary>Eine kurze Einführung ins Camp-Radeln.

Since the release of the Microsoft Flight Simulator 2020, flight simulation has become a more mainstream genre. What flies past many is the existence of an open source flight simulator with a long standing history and way more flexibility in many regards. We take you on a flight through the world of Flightgear... In the first part we will take a look at the history, where the project is headed in the future and how you can make the first steps in the simulator, helping you get in the air. Now that we have an overview what flightgear is, we go on to the second part where we take a look how to interface the flight sim with your own hacked hardware and other systems.

Das Konzept adressiert die Mängel im geltenden Datenschutzrecht, indem es sich auf die vielseitigen Folgen der Datennutzung konzentriert. Das Konzept geht als eigentliches Datengesetz jedoch über den Datenschutz hinaus. Es schafft auch einen Rechtsrahmen für den Umgang mit «Künstlicher Intelligenz» und bietet eine Lösung für die Sekundärnutzung von Daten. Dabei nimmt das neue Konzept die Datenbearbeiter:innen konkret in die Pflicht und ermöglicht eine vertrauensvolle Datennutzung. Ausgehend von der Kritik am zu wenig spezifischen Zweck des geltenden Datenschutzrechts und seinem unklaren Schutzbereich gibt das Datenschutz-Konzept sieben Schutzziele vor: Schutz vor Manipulation, Schutz vor Diskriminierung, Schutz vor Überwachung und Recht auf Anonymität, Schutz vor Beeinträchtigung der Gesundheit sowie der Lebens- und Entwicklungschancen, Recht auf Transparenz und Pflicht zur Sorgfalt, Recht auf Vergessenwerden, Schutz der offenen Gesellschaft und freien Demokratie Basierend auf diesen Schutzzielen ergibt sich ein Konzept für einen wirksamen und zielgerichteten Datenschutz, der Vertrauen schafft und Innovation fördert. Das Konzept stellt die Einhaltung und Durchsetzung der Schutzziele ins Zentrum und löst sich vom Prinzip der Einwilligung zur Datenbearbeitung und der Zweckbindung. Geregelt wird der Umgang mit Daten und nicht bloss mit Personendaten an sich. Das Konzept beinhaltet: Grundsätze zur Datenbearbeitung, wonach Private und staatliche Datenbearbeitungen die Schutzziele für die Individuen und die Gesellschaft wahren müssen. Ein absolutes Verbot für bestimmte Datenbearbeitungen, welche ein zu grosses Risiko für Individuen oder die Gesellschaft bergen und die Schutzziele nicht gewährleisten können (wie biometrische Massenüberwachung und Social Scoring). Eine substantielle Mitbestimmung der Betroffenen, wonach insbesondere eine Datenbearbeitung für diese erkennbar und eine Möglichkeit zu einem einfach wahrzunehmenden Widerspruchsrecht gegeben sein müssen. Bestimmungen zur Durchsetzung des Konzepts wie wirksame Sanktionen, wenn die Schutzziele nicht eingehalten werden. Unter Einhaltung der Schutzziele können Daten und insbesondere auch Personendaten unbeschränkt bearbeitet werden. Dabei werden die Datenbearbeiter:innen jedoch verstärkt in die Pflicht genommen, die Interessen der betroffenen Personen und der Gesellschaft zu wahren. Das Vertrauen in die Datennutzung und die Datenbearbeitung wird dadurch gestärkt. Parallel zum Datenschutz-Konzept arbeitet die Digitale Gesellschaft an einer Datenschutz-Initiative. Die geplante Volksinitiative hat das Ziel, das Konzept in der Bundesverfassung zu verankern. In unserem Vortrag werden wir das Datenschutz-Konzept vorstellen und den Stand der Datenschutz-Initiative erläutern. about this event: https://winterkongress.ch/2024/talks/datenschutz_konzept_und_initiative/ </description> <enclosure url="https://cdn.media.ccc.de/events/dgwk/2024/h264-hd/import-56187-deu-Datenschutz-Konzept_und_-Initiative_hd.mp4" length="363855872" type="video/mp4"/> <pubDate>Sat, 02 Mar 2024 16:30:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/dgwk/2024/h264-hd/import-56187-deu-Datenschutz-Konzept_und_-Initiative_hd.mp4?1711426830</guid> <dc:identifier>374dd414-8358-4458-9459-a4799d27d2ce</dc:identifier> <dc:date>2024-03-02T16:30:00+01:00</dc:date> <itunes:author>Anna Walter, Viktor Györffy</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>import, 56187, 2024, Recht & Politik</itunes:keywords> <itunes:summary>Die Digitale Gesellschaft hat ein neues Datenschutz-Konzept erarbeitet.

(dgwk2024)</title> <link>https://media.ccc.de/v/dgwk2024-56185-den-planet-einfach-brenne</link> <description>Wie wir die gamifizierten Ablenkungen abschütteln und nachhaltige Bewegungen aufbauen Während die letzten Ressourcen des Planeten leer geschlürft werden, befinden sich viele zwischen Wut, Panik & Verzweiflung. Ein Dilemma ist, dass wir in einer hyper-vernetzten Welt leben in der nicht nur Vorteile, sondern auch Nachteile vernetzt sind. Während manche Probleme durch Technologien lösbar sind, sind technologische Lösungen aber nicht universell einsetzbar. Manches, wie etwa Elektro-Autos, sind nur Lösung für Industrie, nicht für den Planeten oder es sind digitale Beruhigungsnuggis für Individuen. Dieser Vortrag begegnet der Klimakrise, indem der Zustand des Planeten in Zusammenhang mit der Wirtschaftsordnung, den politischen Systemen und den daraus resultierenden sozialen Problemen stellt. Es wird die Frage nach Macht und Verantwortlichkeiten gestellt und inwiefern Philosophie und Ethik mit Lösungen verbunden sind. Für eine mögliche Antwort wird aus den Erfahrungen internationaler sozialer Bewegungen geschöpft, um einen Blick auf eine mögliche und nachhaltige Zukunft zu werfen. Die Welt, in der wir leben ist sehr vernetzt auf der wirtschaftlichen Ebene, aber keinesfalls so gut auf der gesellschaftlichen. Verbindungen laufen vor allem über Kabel und Containerschifffe, nicht über die Interaktionen zwischen gesellschaftlichen Gruppen. Und ungeachtet allen Redens über Demokratie und Mitbestimmung fließen Macht und Geld immer noch in die Hände sehr weniger. Und diese wenigen lösen unsere Probleme nicht. Die Herausforderungen, vor denen wir stehen, sind gigantisch. Aber das muss nicht gleichbedeutend mit schrecklich sein – es bedeutet erst einmal, dass es nicht langweilig wird. Und es bedeutet auf gar keinen Fall, dass wir nun unseren Humor verlieren sollten! Dieser Vortrag zielt darauf, Wege aus furchtbar erscheinenden Situationen zu zeigen und euch zugleich zum Lachen zu bringen. Um eine gemeinsame Basis für Überlegungen zu haben, startet der Vortrag mit einer kurzen Analyse der Ursprünge unser jetzigen Situation, unter der Einbeziehung ihrer theoretischen und philosophischen Grundlagen. Dieses gemeinsame Wissen wird dazu genutzt, um im zweiten Schritt vier kurze Matches zu betrachten: Theorien sozialer Bewegungen treten gegen Aufstandsbekämpfungstheorien an, Ethik gegen die Kybernetik, Ideen der Entscheidungsfreiheit gegen Gamifizierung und Meinungsfreiheit gegen Überwachung. Die Ergebnisse werden im letzten Teil dazu genutzt, um sie mit Erfahrungen aus sozialen Bewegungen aus unterschiedlichen Teilen der Welt zu verbinden. In dem den Fäden der Macht gefolgt wird, wird die Frage nach Verantwortung gestellt, um Lösungswege herauszuarbeiten. Denn weder Panik noch Verzweiflung werden den Planeten retten. Aber mit einer guten Bewegung können das. about this event: https://winterkongress.ch/2024/talks/den_planet_einfach_brennen_lassen/ </description> <enclosure url="https://cdn.media.ccc.de/events/dgwk/2024/h264-hd/import-56185-deu-Den_Planet_einfach_brennen_lassen_hd.mp4" length="559939584" type="video/mp4"/> <pubDate>Sat, 02 Mar 2024 14:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/dgwk/2024/h264-hd/import-56185-deu-Den_Planet_einfach_brennen_lassen_hd.mp4?1711343918</guid> <dc:identifier>35d181a9-ccfc-47ea-b1fa-9e45593bf3e4</dc:identifier> <dc:date>2024-03-02T14:00:00+01:00</dc:date> <itunes:author>Katika Kühnreich</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>import, 56185, 2024, Ethik, Wissenschaft, Kultur & Gesellschaft</itunes:keywords> <itunes:summary>Wie wir die gamifizierten Ablenkungen abschütteln und nachhaltige Bewegungen aufbauen Während die letzten Ressourcen des Planeten leer geschlürft werden, befinden sich viele zwischen Wut, Panik & Verzweiflung.

In der Landesvermessung Niedersachsen (LGLN) wurde dafür ein Workflow unter Verwendung verschiedener Open Source Tools entwickelt. Damit soll der manuelle Aufwand bei der Erstellung der Trainingsdaten möglichst minimiert werden und ein qualitativ hochwertiger Datensatz mit hoher räumlicher Abdeckung entstehen, der die Variabilität der Gebäude in Niedersachsen ausreichend abbildet. Als DecSecOps-Team des Landesamtes für Geoinformation und Landesvermessung Niedersachsen (LGLN) entwickeln wir eine Anwendung zur „KI-Gebäudeerkennung“ in Luftbildern. Das Ziel dieser Anwendung ist es, Änderungen in den Gebäudedaten im Amtlichen Liegenschaftskataster-Informationssystem (ALKIS) mit Hilfe von KI-detektierten Hausumringen zu finden. Zum Trainieren der KI-Modelle werden Trainingsdaten aus Niedersachsen verwendet. Diese Trainingsdaten bestehen aus 4-Kanal-Orthophotos (DOP) und normalisierten Oberflächenmodellen (nDOM), sowie Hausumringen als sogenannte „Labels“. Eine manuelle Erstellung und Korrektur dieser Labels ist sehr aufwendig. Aus diesem Grund wurde ein Workflow entwickelt, der aus mehreren Schritten besteht und bereits vorhandene Daten nutzt. Er ermöglicht es Daten in ausgewählten, repräsentativen Bereichen passend zum jeweiligen Luftbild zu editieren. Als Grundlage für diese Labels werden dabei die Gebäude aus ALKIS verwendet. Dies beruht auf der Annahme, dass der Gebäudebestand in den ALKIS-Daten von Niedersachsen größtenteils korrekt ist. Durch eine interaktive Web-GIS-Anwendung in einem Jupyter-Notebook lassen sich mit wenigen Mausklicks Bereiche der Luftbilder anzeigen und mit den vorhandenen ALKIS-Daten überlagern. Somit können die Daten schnell gesichtet und Bereiche identifiziert werden, wo die Gebäude aus ALKIS und das jeweilige Luftbild bereits gut zusammen passen. Diese Bereiche sind 400×400 m bzw. 2000×2000 Pixel groß. Wir bezeichnen sie als „Trainings-Patches“. Die Metadaten dieser „Trainings-Patches“ werden in einer Datenbank gesammelt und bilden einen Pool von möglichen Trainingsdaten. Teilweise passen die ALKIS-Gebäude nicht zum Luftbild: Es kommt vor, dass Neubauten oder Abrisse noch nicht erfasst sind oder Gebäude bzw. Teile von Gebäuden durch Vegetation verdeckt sind. Damit für das KI-Training nur Labels zum Einsatz kommen, die zu den Luftbildern passen, ist es erforderlich, die vorhandenen Gebäudeumringe zu bearbeiten. Dazu nutzen wir QGIS und die darin vorhandenen Möglichkeiten zum Editieren von Polygonen. Diese Aufgabe ist der aufwendigste Teil des Workflows und wird von einem „Label-Team“ im LGLN durchgeführt. Die Herausforderung besteht hier darin, die Daten der „Trainings-Patches“, bestehend aus Bildausschnitt im Luftbild bzw. nDOM sowie den zu editierenden ALKIS-Polygonen in den QGIS-Client der bearbeitenden Person zu laden. Die visuelle Kontrolle der Daten und die Bearbeitung der Polygone kann auch offline erfolgen. Nach der manuellen Bearbeitung der Polygone müssen die Daten in eine Datenbank geschrieben werden. Dafür wurde ein auf FastAPI-basierender Microservice gebaut, der die Datenbereitstellung und Kommunikation zwischen QGIS-Client und Datenbank durchführt. In dieser Demo wird der beschriebene Workflow für die Trainingsdaten-Erstellung vorgestellt und die verwendeten Open Source Tools mit ihren interaktiven GIS-Funktionalitäten demonstriert. about this event: https://pretalx.com/fossgis2024/talk/7S3JKU/ </description> <enclosure url="https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-39047-deu-Workflow_zur_Erstellung_von_Trainingsdaten_fuer_die_KI-Gebaeudeerkennung_hd.mp4" length="605028352" type="video/mp4"/> <pubDate>Fri, 22 Mar 2024 11:45:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-39047-deu-Workflow_zur_Erstellung_von_Trainingsdaten_fuer_die_KI-Gebaeudeerkennung_hd.mp4?1711114066</guid> <dc:identifier>14cb39d6-5a7a-5b2d-a55c-6a8c949acafa</dc:identifier> <dc:date>2024-03-22T11:45:00+01:00</dc:date> <itunes:author>Uwe Breitkopf, Jonas Bostelmann</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>fossgis2024, 39047, 2024, Daten, Datenbanken und Datenprozessierung</itunes:keywords> <itunes:summary>Für die KI-Gebäudeerkennung in Luftbildern wird eine große Menge Trainingsdaten benötigt.

Der Diskurs um Migration und Flucht wird mit zunehmender Selbstverständlichkeit als ein Diskurs der Abwehr und des Ausschlusses der „Anderen“ geführt. Dies drückt sich in immer neuen Gesetzesverschärfungen bis hin zur Forderung nach einer vollständigen Abschaffung des Grundrechtes auf Asyl aus.

Nur vor diesem gesellschaftlichen Hintergrund sind die Wahlerfolge der AfD in Hessen und Bayern zu verstehen. Für uns ist klar: Unter solchen gesellschaftlichen Bedingungen wächst die Gefahr rechten Terrors. Die Zahl der antisemitischen, rassistischen und rechten Angriffe steigt weiterhin, denn Rechte Täter*innen können sich als diejenigen verstehen, die einen vermeintlichen „Volkswillen“ in die Tat umsetzen. Sie finden vermehrt die Ermöglichungsstrukturen, die sie für ihre Taten benötigen – in rechten Organisationen ebenso wie im Netz oder im direkten sozialen Umfeld. Wir wollen im Podcast auf das Jahr 2023 zurückschauen und ausloten, wo wir im Kampf gegen rechten Terror stehen. Was sind unsere Möglichkeiten, zu informieren und zu intervenieren? Wir müssen von Staat und Gesellschaft Aufklärung und Konsequenzen einfordern, die Arbeit von Polizei, Justiz und Parlamenten kritisch beobachten, Verharmlosung und Entpolitisierung entgegentreten, solidarisch sein und Betroffenen in ihren Kämpfen um Anerkennung und Gerechtigkeit beiseite stehen.

Dabei werden verschiedene Einsatzgebiete wie Visualisierung, Analyse, Datenprozessierung und Export einsteigerfreundlich beleuchtet. In diesem Vortrag wird osm2pgsql - ein Tool zum Import von OpenStreetMap-Daten in eine PostgreSQL/PostGIS-Datenbank - vorgestellt. Es wird auf die Installation eingegangen und ein grober Überblick über die Datenbank PostgreSQL und deren räumlicher Erweiterung PostGIS gegeben. Im Anschluss werden einige Grundfunktionen von osm2pgsql erklärt: Wie man beispielsweise Geodaten ins gewünschte Koordinatensystem umwandelt, die Namen der erstellten Tabellen konfiguriert oder Metadaten der OSM-Objekte hinzufügt. Außerdem wird gezeigt, wie man mit Hilfe des Tools "osm2pgsql-replication" automatische Updates in die Datenbank integriert und so immer auf dem neuesten Stand bleibt. Die Nutzung von Lua für den Datenimport im Flex Output-Format wird detailliert erklärt. Dadurch kann der Datenimport entsprechend individueller Anforderungen gestaltet werden. Zum Abschluss werden diverse Beispielanwendungen aufgezeigt, wie z.B. Datenanalyse, -export und die Veröffentlichung von Geodaten im Internet. Dies eröffnet zahlreiche Möglichkeiten, um osm2pgsql zur Verarbeitung und Nutzung von OpenStreetMap-Daten zu verwenden. about this event: https://pretalx.com/fossgis2024/talk/9QUB7F/ </description> <enclosure url="https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-38344-deu-osm2pgsql_-_OSM_Daten_mit_PostGIS_verarbeiten_hd.mp4" length="210763776" type="video/mp4"/> <pubDate>Fri, 22 Mar 2024 10:10:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-38344-deu-osm2pgsql_-_OSM_Daten_mit_PostGIS_verarbeiten_hd.mp4?1711103894</guid> <dc:identifier>ecb7ab81-c26e-5726-8f14-cd941ed1eba0</dc:identifier> <dc:date>2024-03-22T10:10:00+01:00</dc:date> <itunes:author>Jakob Miksch</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>fossgis2024, 38344, 2024, OpenStreetMap</itunes:keywords> <itunes:summary>Der Vortrag gibt einen Überblick über das Tool osm2pgsql, mit dem OpenStreetMap-Daten in eine PostgreSQL/PostGIS-Datenbank importiert werden können.

Seit einiger Zeit kommen vermehrt OpenSource-Verfahren zum Einsatz. Wenngleich diverse Hindernisse den Einsatz von (mehr) OpenSource aktuell noch erschweren oder gar verhindern, bestärken eine Reihe von Erfolgsgeschichten das KRZN, den Weg in Richtung OpenSource im GDI-Kontext in Zusammenarbeit mit kommunalen Akteuren:innen weiterzugehen. Das Kommunale Rechenzentrum Niederrhein (KRZN) stellt seit 2005 für 43 Kommunen und aktuell über 3.500 berechtigte Nutzer:innen in den Kommunalverwaltungen am Niederrhein eine kommunale Geodateninfrastruktur (GDI) bereit und entwickelt diese seitdem kontinuierlich weiter. Bestand die GDI zu Beginn aus einem DesktopGIS für die Datenerfassung und -analyse, einem WebGIS für die Beauskunftung, einer rechtsverbindlichen Liegenschaftskatasterauskunft (auf Basis von ALB und ALK) und einem zentralen GeoDataWarehouse für die Datenhaltung, kommen heute über 35 GIS-Verfahren zum Einsatz - von Fachverfahren für die Pflege von Kanal- und Baumkatastern, einer ALKIS-Verfahrenslösung in all ihren Facetten über ETL-Werkzeuge und Verfahren zur Bereitstellung von OGC-Geoservices bis hin zu Geoportalen und einem Geokatalog. Bis 2018 basierte die GDI ausschließlich auf proprietärer Software. Mit Einführung von deegree, einhergehend mit der Ablösung der bis dato eingesetzten Software für die Bereitstellung von Geoservices, sowie der Bereitstellung des Geoportal Niederrhein auf Basis des Masterportals wurde im Dezember 2019 der erste Meilenstein zur Nutzung von OpenSource-Software gesetzt. Mit der Vereinbarung in einem GDI-Verbandsgremium der nächste Meilenstein: Alle neuen GDI-Verfahren müssen OGC-Standards zwingend unterstützen, bestehende Verfahren müssen diesbezüglich ertüchtigt werden, insofern erforderlich. Es folgten weiteren OpenSource-Verfahren, beispielsweise zur Bereitstellung und Verwaltung von OGC-Geoservices, Werkzeuge zur Bereitstellung eines OpenStreetMap-WMS oder für Management und Bereitstellung von XPlanung-Daten sowie die Bereitstellung eines Geokataloges. Zudem wird PostgreSQL immer häufiger als Datenbanksystem eingesetzt. Alle Verfahren wurden vollständig in die GDI integriert, entweder als Erweiterung, Alternative oder Ersatz für proprietäre Software. Von zentraler Bedeutung ist die Kommunikation über Schnittstellen - i.d.R. Standards des OGC - mit den vorhandenen GDI-Bausteinen. Neben vielen Erfolgsgeschichten gab es jedoch auch Ernüchterung. So wird seit 2021 auch QGIS als DesktopGIS eingesetzt. Jedoch ohne Anbindung an das zentrale GeoDataWarehouse. Neben technischen Gründen ist das Fehlen eines zentralen Berechtigungsverfahrens (auf weit über 20.000 Objektklassen) ein Grund für die nicht erfolgte Anbindung. Die Praxis zeigt jedoch, im Zusammenspiel von QGIS und OGC-Geoservices kann dennoch viel erreicht werden. Neben der rein technischen Sicht ist die stetige Kommunikation aller betroffenen Akteure:innen für den Erfolg einer GDI unabdingbar. OpenSource kann sowohl Kommunikation als auch das GDI-Management unterstützen. Verfahren für Wikis, Dashboards und Kanban seien als Beispiele genannt. Der Vortrag soll aufzeigen, • wie das KRZN die vorhandene GDI Schritt für Schritt durch (mehr) OpenSource-Anwendungen „modernisiert“, • wo es Hindernisse für den Umstieg auf OpenSource-Verfahren gibt und • warum der große Wurf – Umstieg auf 100%-OpenSource – eine immense Herausforderung ist (und womöglich auch nicht umsetzbar sein wird). about this event: https://pretalx.com/fossgis2024/talk/LMFGWP/ </description> <enclosure url="https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-38904-deu-Geodateninfrastruktur_Step_by_step_von_proprietaerer_zu_offener_Software_hd.mp4" length="296747008" type="video/mp4"/> <pubDate>Fri, 22 Mar 2024 09:35:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-38904-deu-Geodateninfrastruktur_Step_by_step_von_proprietaerer_zu_offener_Software_hd.mp4?1711102662</guid> <dc:identifier>af43dde0-cebd-5def-9a75-2e9e57a3e043</dc:identifier> <dc:date>2024-03-22T09:35:00+01:00</dc:date> <itunes:author>Stefan Peuser</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>fossgis2024, 38904, 2024, Praxisberichte</itunes:keywords> <itunes:summary>Das KRZN stellt den Kommunen am Niederrhein eine kommunale Geodateninfrastruktur (GDI) bereit und entwickelt diese kontinuierlich weiter.

Sie bietet viele neue Werkzeuge zur Visualisierung von Rasterdaten und über 150 Algorithmen, mit denen sich umfangreiche Analyse-Workflows, etwa zur Abschätzung biophysikalischer Variablen, erstellen lassen. Wir stellen die EnMAP-Box vor, zeigen ihre neuesten Features und geben einen Ausblick auf die weiteren Entwicklungsschritte. Dank Erdbeobachtungsmissionen wie EnMAP und PRISMA sind hyperspektrale Rasterdaten inzwischen kostenfrei, für große Gebiete und verschiedene Aufnahmezeitpunkte verfügbar. Ihre Nutzung stellt allerdings viele Anwender*innen vor Herausforderungen: Herkömmliche GIS- und Fernerkundungssoftware ist oft wenig geeignet für einen effizienten Umgang mit Hyperspektraldaten, die oft über 200 Wellenlängen in teils hoch-korrelierten Kanälen abbilden. Zudem bieten sie meist auch keine Möglichkeit, die zu den Rasterdaten gehörigen Metadaten in Wert zu setzen. Dies ändert sich mit der EnMAP-Box. Sie ergänzt QGIS um essenzielle Fähigkeiten zur Analyse und Auswertung hyperspektraler Rasterdaten, etwa Nutzung beiliegender Wellenlängeninformationen zur schnellen Visualisierung geeigneter Kanalkombinationen, oder das Lesen, Erstellen und Schreiben von Spektralbibliotheken. Die EnMAP-Box ergänzt das QGIS Processing Framework um mehr als 150 Algorithmen, die einen einfachen Zugang zu state-of-the-art Methoden aus dem Bereich des Maschinellen Lernens bieten. Damit lassen sich umfangreiche Workflows zur automatisierten Prozessierung von Fernerkundungsdaten realisieren, etwa um Landnutzungsklassifizierungen oder Karten von biophysikalischen Variablen zu erhalten.

Sie bietet viele neue Werkzeuge zur Visualisierung von Rasterdaten und über 150 Algorithmen, mit denen sich umfangreiche Analyse-Workflows, etwa zur Abschätzung biophysikalischer Variablen, erstellen lassen. Wir stellen die EnMAP-Box vor, zeigen ihre neuesten Features und geben einen Ausblick auf die weiteren Entwicklungsschritte. Dank Erdbeobachtungsmissionen wie EnMAP und PRISMA sind hyperspektrale Rasterdaten inzwischen kostenfrei, für große Gebiete und verschiedene Aufnahmezeitpunkte verfügbar. Ihre Nutzung stellt allerdings viele Anwender*innen vor Herausforderungen: Herkömmliche GIS- und Fernerkundungssoftware ist oft wenig geeignet für einen effizienten Umgang mit Hyperspektraldaten, die oft über 200 Wellenlängen in teils hoch-korrelierten Kanälen abbilden. Zudem bieten sie meist auch keine Möglichkeit, die zu den Rasterdaten gehörigen Metadaten in Wert zu setzen. Dies ändert sich mit der EnMAP-Box. Sie ergänzt QGIS um essenzielle Fähigkeiten zur Analyse und Auswertung hyperspektraler Rasterdaten, etwa Nutzung beiliegender Wellenlängeninformationen zur schnellen Visualisierung geeigneter Kanalkombinationen, oder das Lesen, Erstellen und Schreiben von Spektralbibliotheken. Die EnMAP-Box ergänzt das QGIS Processing Framework um mehr als 150 Algorithmen, die einen einfachen Zugang zu state-of-the-art Methoden aus dem Bereich des Maschinellen Lernens bieten. Damit lassen sich umfangreiche Workflows zur automatisierten Prozessierung von Fernerkundungsdaten realisieren, etwa um Landnutzungsklassifizierungen oder Karten von biophysikalischen Variablen zu erhalten. Mittlerweile wird die EnMAP-Box in zahlreichen Forschungseinrichtungen wie auch in der Privatwirtschaft genutzt.

SAR Bilder sind von großem Wert in der Katastrophenhilfe um direkt nach einem Katastrophenfall eine Einschätzung des entstandenen Schadens zu gewinnen - sie können auch nachts und durch eine Wolkendecke aufgenommen werden. In diesem Vortrag wird RaySAR vorgestellt, sowie Ansätze, wie RaySAR bei der Detektion von Gebäudeschäden eingesetzt werden könnte. Im Katastrophenfall, zum Beispiel nach einem Erdbeben, Tsunami oder Sturm, müssen Entscheidungen getroffen werden, wie die Ressourcen der Katastrophenhilfe eingesetzt werden. Dafür ist es notwendig, dass Entscheidungsträger möglichst gut über den entstandenen Schaden und dessen räumliche Verteilung informiert werden. Fernerkundungsmethoden spielen eine wichtige Rolle in dieser Aufgabe, da sie großflächige Aufnahmen zur Verfügung stellen ohne dass sich Gutachter vor Ort in Gefahr bringen müssen. Besonders attraktiv sind Synthetic Aperture Radar (SAR) Aufnahmen, weil diese unabhängig von Lichtverhältnissen und Wetterbedingungen aufgenommen werden können und hochauflösende Daten liefern. Radardaten bringen aber auch einige Schwierigkeiten mit sich. Die Funktionsweise eines Radarsensors unterscheidet sich entscheidend von dem eines optischen Sensors, weshalb SAR Bilder schwieriger zu interpretieren sind als optische Bilder.

SAR Bilder sind von großem Wert in der Katastrophenhilfe um direkt nach einem Katastrophenfall eine Einschätzung des entstandenen Schadens zu gewinnen - sie können auch nachts und durch eine Wolkendecke aufgenommen werden. In diesem Vortrag wird RaySAR vorgestellt, sowie Ansätze, wie RaySAR bei der Detektion von Gebäudeschäden eingesetzt werden könnte. Im Katastrophenfall, zum Beispiel nach einem Erdbeben, Tsunami oder Sturm, müssen Entscheidungen getroffen werden, wie die Ressourcen der Katastrophenhilfe eingesetzt werden. Dafür ist es notwendig, dass Entscheidungsträger möglichst gut über den entstandenen Schaden und dessen räumliche Verteilung informiert werden. Fernerkundungsmethoden spielen eine wichtige Rolle in dieser Aufgabe, da sie großflächige Aufnahmen zur Verfügung stellen ohne dass sich Gutachter vor Ort in Gefahr bringen müssen. Besonders attraktiv sind Synthetic Aperture Radar (SAR) Aufnahmen, weil diese unabhängig von Lichtverhältnissen und Wetterbedingungen aufgenommen werden können und hochauflösende Daten liefern. Radardaten bringen aber auch einige Schwierigkeiten mit sich. Die Funktionsweise eines Radarsensors unterscheidet sich entscheidend von dem eines optischen Sensors, weshalb SAR Bilder schwieriger zu interpretieren sind als optische Bilder. Außerdem fehlen oft hochauflösende Aufnahmen, die kurze Zeit vor einer Katastrophe aufgenommen wurden, denn der Sensor muss für die Aufnahme von Bildern mit höchster Auflösung längere Zeit auf das Ziel ausgerichtet bleiben und eine dauerhafte, flächendeckende Aufnahme ist nicht möglich. Für sogenannte change detection Methoden, die Unterschiede zwischen Aufnahmen von vor der Katastrophe und nach der Katastrophe festellen, fehlen deshalb Referenzdaten, die im Fall optischer Bilder deutlich öfter vorhanden sind.

Dazu wurde eine Reihe von Metriken entwickelt. Mit denselben Metriken haben wir auch andere frei verfügbare Datensätze (z.B.: OSM) ausgewertet, bestehende Differenzen analysiert und daraus Aussagen über Vollständigkeit, Aktualität und Genauigkeit der jeweiligen Hausumringe abgeleitet. Im Landesamt für Geoinformation und Landesvermessung Niedersachsen (LGLN) wird eine „KI-Gebäudeerkennung“ entwickelt, um auf Grundlage von digitalen Orthophotos (DOP) den Gebäudebestand im Amtlichen Liegenschaftskataster-Informationssystem (ALKIS) zu aktualisieren. Dabei müssen systematisch die Differenzen zwischen den von der KI erkannten Gebäuden und den Hausumringen aus ALKIS berechnet werden. Diese Differenzen liefern Hinweise auf Unstimmigkeiten in den ALKIS-Daten. Verwendet man manuell erzeugte Referenz-Daten, erlauben die Differenzen dagegen eine Beurteilung der Qualität der KI-Modelle. Um die Differenzen zwischen den beiden Datensätzen quantifizieren zu können, nutzen wir eine Reihe von Metriken: Darunter Standards wie Intersection over Union (IoU), Mean Average Precision und F1-Score, sowie Ähnlichkeiten der geometrischen Eigenschaften der Hausumringe. Für die Berechnung dieser Metriken haben wir auf Grundlage von GeoPandas und weiterer Open Source Software ein Python-Package entwickelt, welches wir bereits produktiv einsetzen.

Dazu wurde eine Reihe von Metriken entwickelt. Mit denselben Metriken haben wir auch andere frei verfügbare Datensätze (z.B.: OSM) ausgewertet, bestehende Differenzen analysiert und daraus Aussagen über Vollständigkeit, Aktualität und Genauigkeit der jeweiligen Hausumringe abgeleitet. Im Landesamt für Geoinformation und Landesvermessung Niedersachsen (LGLN) wird eine „KI-Gebäudeerkennung“ entwickelt, um auf Grundlage von digitalen Orthophotos (DOP) den Gebäudebestand im Amtlichen Liegenschaftskataster-Informationssystem (ALKIS) zu aktualisieren. Dabei müssen systematisch die Differenzen zwischen den von der KI erkannten Gebäuden und den Hausumringen aus ALKIS berechnet werden. Diese Differenzen liefern Hinweise auf Unstimmigkeiten in den ALKIS-Daten. Verwendet man manuell erzeugte Referenz-Daten, erlauben die Differenzen dagegen eine Beurteilung der Qualität der KI-Modelle. Um die Differenzen zwischen den beiden Datensätzen quantifizieren zu können, nutzen wir eine Reihe von Metriken: Darunter Standards wie Intersection over Union (IoU), Mean Average Precision und F1-Score, sowie Ähnlichkeiten der geometrischen Eigenschaften der Hausumringe. Für die Berechnung dieser Metriken haben wir auf Grundlage von GeoPandas und weiterer Open Source Software ein Python-Package entwickelt, welches wir bereits produktiv einsetzen. Dieses Tool erlaubt uns auch einen Vergleich mit anderen frei verfügbaren Datensätzen (wie z.B. den Gebäuden aus OSM oder Microsofts Building Footprints). Es ist damit möglich, gezielt für ein Gebiet die Übereinstimmung der Hausumringe zwischen den jeweiligen Datensätzen zu messen.

Jahrhunderts bis heute verändert hat. Dazu werden Methoden erarbeitet, um Karteninhalte aus digitalisierten Altkartenbeständen automatisiert zu extrahieren.Die im Projekt entstehenden Ergebnisse werden als offene Geodaten, die Methoden in einem QGIS Plug-In bereitgestellt. Die Klimaforschung benötigt, wie auch andere Disziplinen der Erdsystemforschung, Zeitreihendaten über lange Zeiträume. Der Klimaforschung fehlen derzeit flächendeckende, hochaufgelöste Daten zur Landnutzung bzw. Landbedeckung der letzten Jahrhunderte für die Verbesserung der Erdsystemmodellierung. Der Landnutzungskomponente und speziell dem anthropogenen Landwandel kommt eine bedeutende Rolle zu, insbesondere seit dem Beginn der Industriellen Revolution. Eine wichtige Datenquelle für die Zeit vor den siebziger Jahren des 20. Jahrhunderts sind kartographische Abbildungen der Erdoberfläche in Form archivierter topographischer Kartenwerke. Die Georeferenzierung topographischer Karten, das Extrahieren der Landbedeckungsformen verschiedener Zeitabschnitte und deren Klassifizierung bilden die Grundlage für diese vergleichenden Analysen. Der Analyseprozess ist aufgrund der großen Datenmengen nur automatisiert durchführbar. Die räumliche und zeitliche Analyse des sehr unterschiedlichen Kartenmaterials, stellt eine große Herausforderung dar. Diese reicht von der Beschaffung der Karten, über den semantischen Abgleich, bis hin zu nicht immer geklärten Lizenzrechten. Besonderes Augenmerk ist auf die Darstellung der Validität der Ergebnisse zu legen. Da es sich um ein relativ junges Fachgebiet handelt, gibt es noch keine automatisierten Lösungen. In einem neuen Gemeinschaftsprojekt zwischen dem Bundesamt für Kartographie und Geodäsie (BKG) und dem Leibniz-Institut für ökologische Raumentwicklung e.V. (IÖR) werden nun Methoden entwickelt und aus analogen Karten abgeleitete Daten bereitgestellt. Ziel des Projektes ist, zu ermitteln, in welchem Maße sich die Landbedeckung in Deutschland vom Anfang des 19. Jahrhundert bis heute verändert hat. Das Projekt greift auf die ältesten verfügbaren Landesaufnahmen zurück und ergänzt die Zeitreihen des IÖR-Monitors durch Daten, die aus historischen Kartenwerken zu entnehmen sind. Das Projekt wird mit Open Source Software durchgeführt. Die Ergebnisse werden im IÖR-Monitor als Open Data, die Analysealgorithmen auf GitHub als Open Source bereitgestellt. Zu Erweiterung der Methodenforschung mit KI-Technologien, hat das BKG auch ein Forschungsprojekt unter Beteiligung der Leibniz Universität Hannover und der Jade Hochschule gestartet. Da die Dekarbonisierung ein unverzichtbares Element eines nachhaltigen Ökosystems ist, wird besondere Aufmerksamkeit auf Daten gelegt, die für den Dekarbonisierungsprozess genutzt werden können. Die Kohlendioxid-Speicherkapazität der Wälder ist unter anderem vom Alter eines Waldes abhängig. Aus diesem Grund ist die Darstellung der Entwicklung von Waldgebieten im Fokus unserer Studie. Um die Renaturierung vor Mooren als bedeutende CO2-Speicher zu fördern, werden verlässliche Informationen über ehemalige Moorflächen geliefert.

Jahrhunderts bis heute verändert hat. Dazu werden Methoden erarbeitet, um Karteninhalte aus digitalisierten Altkartenbeständen automatisiert zu extrahieren.Die im Projekt entstehenden Ergebnisse werden als offene Geodaten, die Methoden in einem QGIS Plug-In bereitgestellt. Die Klimaforschung benötigt, wie auch andere Disziplinen der Erdsystemforschung, Zeitreihendaten über lange Zeiträume. Der Klimaforschung fehlen derzeit flächendeckende, hochaufgelöste Daten zur Landnutzung bzw. Landbedeckung der letzten Jahrhunderte für die Verbesserung der Erdsystemmodellierung. Der Landnutzungskomponente und speziell dem anthropogenen Landwandel kommt eine bedeutende Rolle zu, insbesondere seit dem Beginn der Industriellen Revolution.

Es dient der Datenaufbereitung für und der Ergebnisdarstellung von hydraulischen Simulationen zu kommunalen Entwässerungssystemen und beinhaltet zahlreiche Datenaustauschformate. Neu entwickelt werden aktuell die Zustandserfassung und -bewertung von Kanalnetzen sowie die 2D- und 3D-Ergebnisdarstellung von gekoppelten Kanalnetz- und Oberflächenabflusssimulationen. QKan besteht aus zahlreichen QGIS-Plugins sowie einer SpatiaLite-Datenbank. Mit QKan können kommunale Kanalnetze erfasst und neu geplant werden oder über eine der zahlreichen Schnittstellen importiert werden. Für den hydraulischen Nachweis mit mehreren der in Deutschland gängigen Simulationsprogramme besteht ein Workflow zur Datenaufbereitung, der auf der Nutzung von frei verfügbaren Geodaten (Flurstücke, Straßen, Gebäude) oder vergleichbarer Geodaten aus anderen Quellen basiert. Für das Simulationsprogramm "HYSTEM-EXTRAN" (ITWH, Hannover) ist eine Visualisierung und Animation der Ergebnisse integriert, die sich seit kurzem auch auf die 3D-Visualisierung und Animation von gekoppelten Simulationen erstreckt. Da ein QKan-Projekt lediglich aus Projektdatei und der SpatiaLite-Datenbank besteht, können die Projektdaten einfach weitergegeben werden. Zusammen mit den (meistens sehr umfangreichen) Ergebnisdaten kann der Empfänger der Daten selbständig die Simulationsergebnisse auswerten und in Längsschnitten und Animationen visualisieren. Ähnlich wie im TESKI-Modul Abwasserentsorgung (Projektname QGEP) der Schweizter QGIS-Anwendergruppe enthält QKan einen Funktionsbereich Kanalzustandsverwaltung. Dieser umfasst aktuell den Import von Untersuchungsdaten, eine Zustandbewertung sowie die Verwaltung und Betrachtung von Inspektionsbildern und -videos. Aktuell in der Entwicklung befinden sich die Erstellung von Zustandsberichten. QKan umfasst zusätzlich eine Vielzahl weiterer Funktionalitäten wie z. B. frei konfigurierbare Plausibilitätskontrollen. Eine Besonderheit stellt die erweiterte Clipboardfunktion dar, die vor der Datenübernahme aus der Zwischenablage die zutreffenden Attributbezeichnungen plausibel errät und dabei unabhängig von der Reihenfolge die richtige Zuordnung der Attribute vornimmt.

Im Vortrag wird auch kurz auf die ersten Anwendungsfälle in der Praxis eingegangen. about this event: https://pretalx.com/fossgis2024/talk/XZDJVU/ </itunes:summary> <itunes:duration>00:28:37</itunes:duration> </item> <item> <title>QGIS Plugin: What's the impact of my installed dam on the vegetation around it?

Die Suchoberflächen der meisten Geoportale arbeiten auf eigenen, proprietären Interfaces, die den menschlichen Nutzern eine komfortable Suche ermöglichen. Der standardisierten CSW-Schnittstelle kommt praktisch also nur eine untergeordnete Bedeutung zu. Wenn man jedoch automatistert Datencaches erstellen will, kommt man um diese Schnittstelle nicht herum, sie ist das einzige maschinenlesbare Interface der europäischen Geodateninfrastrukturen. Neben der Schnittstelle für den Zugriff auf die Infrastrukturen, muss man sich auch damit auseinandersetzen, wie die Datencaches physikalisch abgelegt werden können. Hier bietet sich das Geopackage Format des OGC an. Es ist weltweit das einzige Format, das sowohl die kombinierte Ablage von Raster- und Vektordaten, als auch die ihrer zugehörigen Metadaten ermöglicht. In einem Proof of Concept wurde eine Python-Bibliothek erstellt, die Raster- und Vektordaten aus einer europäischen GDI extrahieren kann und diese in einem Geopackage speichert. Dabei werden nicht nur die Daten selbst, sondern auch die zugehörigen ISO-Metadaten abgelegt. Damit ist man theoretisch auch in der Lage die Informationen im Geopackage automatisch zu aktualisieren, wenn der Datenanbieter neue Metadaten bereitstellt.

Aber der Reihe nach und vorab ein paar Worte zu openrouteservice und RoutingPlus. Der openrouteservice (ORS) des Heidelberg Institute für Geoinformation Technology (HeiGIT) bietet umfangreiche Routing-Dienste, die auf OpenStreetMap-Daten basieren. Er ist aber mehr als nur Routing, denn der ORS bietet auch Erreichbarkeitsanalysen mit Isochronen, Entfernungsmatrizen, Berechnung von ÖPV, spezifische Suchmöglichkeiten bezüglich POIs, und andere Einstellungen, z. B. Strecken mit vermindertem Hitzestress und Geräuschbelastung zu wählen. Basierend auf ORS und betrieben durch das Bundesamt für Kartographie und Geodäsie (BKG) stellt das Projekt RoutingPlus seit mehreren Jahren einen etablierten Routing-Dienst des Bundes dar. Dabei werden gemeinsam verschiedene Erweiterungen des ORS entwickelt, wie die Berechnung europaweiter Isochronen in Sekundenbruchteilen oder mit statistischen Verkehrsdaten angereichertes Routing. Bei RoutingPlus zeichnet sich der ORS zudem primär durch eine herausragende und leistungsstarke Performance mit zuverlässigen Ergebnissen aus. Im Zuge der kontinuierlichen, gemeinsamen Entwicklung stehen neben den Verbesserungen in Infrastruktur, Funktionen und Oberflächen erhebliche Herausforderungen an. Durch die Modernisierung und Anpassung von Infrastruktur, Funktionen und Oberflächen wird der Betrieb von RoutingPlus dabei den modernen Anforderungen eines Softwarebetriebs angepasst. Die Anforderungen reichen von der Einhaltung des BSI-Grundschutzes, über die Berechnung der CO₂-Emission pro Route und anderen Kundenanforderungen bis hin zur hohen Bedienbarkeit graphischer Benutzeroberflächen auf verschiedensten Endgeräten.

Bei dem vorgestellten Vorgehen werden dabei nur Open Data und Open Source Tools verwendet. In Deutschland ist die Zielsetzung formuliert worden, den Anteil des Bruttostromverbrauchs, der aus erneuerbaren Energien gewonnen wird, bis zum Jahr 2030 im Vergleich zu heute zu verdoppeln. Die Nutzung von Solarenergie, insbesondere auf Gebäuden und Freiflächen, spielt dabei eine entscheidende Rolle bei der Erreichung dieser Ziele. Eine zentrale Voraussetzung für den erfolgreichen Ausbau der Solarenergie, ist die genaue Ermittlung der Solarpotentialflächen auf Gebäuden. Hierzu wurde eine prototypische Untersuchung durchgeführt, in der verschiedene Faktoren berücksichtigt wurden. Im vorgestellten Beitrag wird die Methodik vorgestellt, den Anteil des ausgeschöpften Solarpotentials und der wertvollen Freiflächen auf Dächern in einem Testgebiet zu identifizieren. Der Workflow arbeitet auf Open Data mit Open Source Tools zur Analyse und Berücksichtigung wichtiger Faktoren, die für die zukünftige Solaranlageninstallation genutzt werden könnten. Dieses Ergebnis eröffnet die Möglichkeit, konkrete Handlungsempfehlungen zu erarbeiten. Die Identifizierung und Nutzung von Solarpotentialflächen auf Gebäuden ist von entscheidender Bedeutung für die Transformation des deutschen Energiesystems hin zu mehr Nachhaltigkeit und Umweltfreundlichkeit. Dieser Beitrag verdeutlicht die Notwendigkeit und die Möglichkeiten, die sich durch eine Analyse der Solarpotentiale bieten, und unterstreicht die Bedeutung der Solarenergie als treibende Kraft in der Energiewende Deutschlands. about this event: https://pretalx.com/fossgis2024/talk/HV8P83/ </description> <enclosure url="https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-38887-deu-Ermittlung_von_Solarpotentialflaechen_auf_Gebaeuden_hd.mp4" length="146800640" type="video/mp4"/> <pubDate>Thu, 21 Mar 2024 09:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-38887-deu-Ermittlung_von_Solarpotentialflaechen_auf_Gebaeuden_hd.mp4?1711015529</guid> <dc:identifier>dcf6d175-fa3d-5433-8a7e-37bbc7372d1c</dc:identifier> <dc:date>2024-03-21T09:00:00+01:00</dc:date> <itunes:author>Sarah Schütz, Elena Zentgraf</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>fossgis2024, 38887, 2024, Raum-zeitliche Analysen und Modelle</itunes:keywords> <itunes:summary>Im Vortrag wird gezeigt, wie eine Analyse der aktuellen und potentiellen Situation der Solarenergienutzung eine mögliche Grundlage für den Ausbau erneuerbaren Energien sein kann.

Dies macht OpenDRIVE endlich in herkömmlichen GIS-Werkzeugen nutzbar! In der Automobilindustrie und Verkehrssystemtechnik haben sich fahrstreifengenaue Straßendaten (HD-Karten) als wichtige Komponenten für die Funktionsentwicklung und -validierung und auch für den späteren Produktivbetrieb herauskristallisiert. Anwendungen des autonomen Fahrens, der Fahrsimulation und der Verkehrssimulation sind oft auf spezielle technische Straßenbeschreibungsformate angewiesen, von denen sich OpenDRIVE [1] als offener Industriestandard entwickelt hat. Das OpenDRIVE-Datenmodell bündelt die mathematische, kontinuierliche Modellierung der Straßen- und Fahrstreifengeometrie mit allen notwendigen topologischen Verknüpfungen und semantischen Informationen der verkehrsregelnden Infrastruktur (Schilder, Ampeln, usw.). Die Modellierungskomplexität und der Abbildungsumfang von OpenDRIVE machen die Datenerfassung und Objektannotation zu einer anspruchsvollen Aufgabe, die meistens von der Automobilindustrie finanziert und von Mobile-Mapping-Dienstleistern durchgeführt wird. In letzter Zeit zeigen auch öffentliche Einrichtungen erhöhtes Interesse an solchen Daten, insbesondere im Zusammenhang mit der Verkehrsplanung und der Instandhaltung der Straßeninfrastruktur. Allerdings sind solche OpenDRIVE-Daten für amtliche Einrichtungen oft „unerreichbar“ oder nur umständlich nutzbar, obwohl sie den eigenen urbanen Raum thematisieren. Die Werkzeugkompatibilität für OpenDRIVE beschränkt sich auf kommerzielle Software und es fehlt die Integration in gängige GIS-Werkzeuge. Unser Softwarebeitrag [2] erweitert die etablierte Geospatial Data Abstraction Library (GDAL) [3] und wandelt OpenDRIVE-Straßenelemente in OGC Simple Features [4] um, die von den meisten kostenlosen und kommerziellen GIS-Tools ad hoc verarbeitet werden können! So können OpenDRIVE-Datensätze beispielsweise auch direkt in QGIS geladen werden. Unser Ansatz ermöglicht eine leichtgewichtigere Interaktion mit OpenDRIVE-Daten als beispielsweise die intermediäre Konvertierung zu CityGML mit r:trån [5]. Indem wir die Automobil-Domäne näher an die GIS-Domäne heranbringen, möchten wir den interdisziplinären Wissenstransfer und die Schaffung einer vernetzten Forschungsgemeinschaft fördern. Mit unserer offenen Softwareerweiterung ermöglichen wir Behörden und Forschungseinrichtungen einen leichteren Zugang zu hochgenauen Straßendaten, die sonst oft nur der Industrie vorbehalten sind. Im Umkehrschluss profitiert die (Automobil-)Industrie von etablierten Werkzeugen und Datenbereitstellungsdiensten des Geodatenumfelds, mit dem sie normalerweise nicht verkehrt.

Gemeinsam wollen wir (keine KI-Experten, aber reichlich Praxiserfahrung) Begriffe klären, konkrete Anwendungsbeispiele vorstellen und dabei auch wichtige offene Fragen zur Diskussion stellen. Dieser Vortrag nimmt Sie mit auf eine Reise durch die spannende Umbruchszeit, in der sich auch unsere Branche befindet und soll Diskurs anregen. Unser Vortrag "KI, GIS, EO & FOSS: Erfahrungen & offene Fragen rund um artifizielle Intelligenz" wirft einen Blick auf die aufregenden Entwicklungen im Bereich künstliche Intelligenz und deren Anwendung in Geoinformationssystemen und Earth Observation. Wir möchten klarstellen, dass die Vortragenden Praktiker und Entwickler sind, nicht aber ausgewiesene KI-Experten. Unsere Betrachtung der Branche, langjährige Erfahrung sowie unser Streben nach Innovation haben uns jedoch dazu motiviert, dieses spannende Thema zu erkunden und unsere Erfahrungen zu teilen. Unsere Präsentation beginnt mit einer Klärung von Begriffen wie KI, Machine Learning und Deep Learning, um ein gemeinsames Verständnis zu schaffen. Wir werden auch einige prominente KI-Produkte/Software (z.b. ChatGPT, Dall-E 2, Midjourney usw.) kurz erläutern. Anschließend werden wir eigene konkrete Beispiele für KI-Anwendungen in GIS und EO präsentieren, darunter die Generierung von Trainingsdaten für Bildklassifikationen und die Nutzung von textbasierter KI zur Unterstützung bei der Programmierung. Darüber hinaus möchten wir wichtige offene Fragen diskutieren und Feedback von der Community sammeln. Themen wie Lizenzierung von KI-generiertem Code, Überprüfbarkeit von KI-Entscheidungen (deshalb mögen wir doch FOSS auch so sehr), ethische Aspekte und vielleicht auch die Zukunft unserer Branche stehen im Mittelpunkt. Unsere Präsentation soll zum Nachdenken anregen und den Dialog über die Chancen und Herausforderungen der KI in unserem Umfeld fördern. Wir freuen uns darauf, weitere Aspekten in sich hoffentlich anschließenden Folgediskussionen zu ergründen. Hinweis: Diese Einreichung wurde mithilfe von ChatGPT erstellt.

Themen wie Lizenzierung von KI-generiertem Code, Überprüfbarkeit von KI-Entscheidungen (deshalb mögen wir doch FOSS auch so sehr), ethische Aspekte und vielleicht auch die Zukunft unserer Branche stehen im Mittelpunkt. Unsere Präsentation soll zum Nachdenken anregen und den Dialog über die Chancen und Herausforderungen der KI in unserem Umfeld fördern. Wir freuen uns darauf, weitere Aspekten in sich hoffentlich anschließenden Folgediskussionen zu ergründen. Hinweis: Diese Einreichung wurde mithilfe von ChatGPT erstellt.

Ein Prozessablauf kombiniert Open Source Software und OpenStreetMap-Daten, um die Meldungen räumlich darzustellen. Offene Standards ermöglichen die einfache Nutzung der Geodaten. Der Vortrag zeigt Ergebnisse für Frankfurt am Main und diskutiert Herausforderungen sowie mögliche Verbesserungen. Pressemitteilungen spielen eine wichtige Rolle bei der Verbreitung von Informationen von staatlichen Institutionen. Auch Polizeibehörden veröffentlichen sogenannte Polizeimeldungen. Hierbei berichtet die jeweils zuständige Polizeibehörde unter anderem von begangenen Straftaten in einer Region. Durch die fortschreitende Digitalisierung können diese Pressemitteilungen auf Presseportalen strukturiert angezeigt und nachverfolgt werden. Auch das Polizeipräsidium Frankfurt am Main veröffentlicht diese Pressemitteilungen. Allerdings enthalten Polizeimeldungen normalerweise keine genauen räumlichen Daten, sondern liefern textbasierte Informationen über die begangenen Straftaten. Dadurch sind räumliche Analysen oder Visualisierungen der in den Texten enthaltenen Informationen nur mit viel Aufwand umsetzbar. Durch den Einsatz von Open Source Software und dem Einbinden von freien OpenStreetMap Daten können die Polizeimeldung räumlich verortet und thematisch kategorisiert werden. Der Vortrag stellt den entstandenen prototypischen Prozessablauf vor, welcher verschiedene digitale Verarbeitungsschritte miteinander kombiniert, um textbasierte Polizeimeldungen räumlich zu visualisieren. Durch das Verwenden von offenen Standards und Schnittstellen, wird eine einfache Weiterverarbeitung oder Einbindung der gewonnenen Geodaten gewährleistet. Die für Frankfurt am Main entstandenen Ergebnisse werden vorgestellt und die Schwierigkeiten einer automatisierten Verarbeitungskette aufgezeigt. Der Vortrag schließt mit einem Ausblick auf mögliche Optimierungen und Überarbeitungen ab. about this event: https://pretalx.com/fossgis2024/talk/NPYHFS/ </description> <enclosure url="https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-38920-deu-Analyse_und_Visualisierung_von_Polizeimeldungen_Eine_Fallstudie_fuer_Frankfurt_a_M_hd.mp4" length="351272960" type="video/mp4"/> <pubDate>Thu, 21 Mar 2024 09:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-38920-deu-Analyse_und_Visualisierung_von_Polizeimeldungen_Eine_Fallstudie_fuer_Frankfurt_a_M_hd.mp4?1711013210</guid> <dc:identifier>613ccdb7-5873-5f3e-8b90-1093af66b116</dc:identifier> <dc:date>2024-03-21T09:00:00+01:00</dc:date> <itunes:author>Johannes Frank</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>fossgis2024, 38920, 2024, Daten, Datenbanken und Datenprozessierung</itunes:keywords> <itunes:summary>Polizeimeldungen von Polizeibehörden informieren unter anderem über Straftaten ohne genaue Ortsangaben.

Wir zeigen, wie wir diese Kartensätze in QGIS als Thick/Deep Map erfassen und für die denkmalwissenschaftliche Forschung aufbereiten und nutzen. Im Zweiten Weltkrieg haben die Stadtplanungsämter auf Stadtplänen die Schäden von Luftangriffen kartiert, um Aufräumarbeiten, nutzbaren Wohnraum, aber auch zukünftigen Neubau zu planen. Für die Stadt Nürnberg liegen uns eine Reihe von Schadensplänen und andere thematische Karten auf Grundlage der gleichen Stadtgrundkarte vor, die unter anderem die Zunahme der Schäden nach aufeinanderfolgenden Luftschlägen dokumentieren. Im Rahmen des UrbanMetaMapping-Projekts¹ zu Kriegsschadenskartierungen des Zweiten Weltkriegs und der Nachkriegszeit am Kompetenzzentrum für Denkmalwissenschaften und –technologien (KDWT)² kartieren wir die Altstadt Nürnbergs hausgenau in QGIS und erstellen durch Überlagerung und Annotierung der unterschiedlichen thematischen (Schadens-)Karten eine Thick Map / Deep Map als Arbeitsgrundlage für weitere Forschungsfragen. Die Überführung der Papierkarten in GIS bietet uns zahlreiche Vorteile: GIS bietet einfache Möglichkeiten für Bemaßung/Quantifizierung, z.B. um das Ausmaß von Zerstörungen quantitativ zu erfassen. Die Überlagerung der unterschiedlichen thematischen und Schadens-Karten erlaubt die Darstellung zeitlicher Abläufe wie auch die Abfrage von Querbeziehungen zur Verknüpfung unterschiedlicher Kartenthematiken. Damit lassen sich qualitative Aussagen sowohl über den Inhalt der Karten als auch die Kartierung selbst treffen. Unser Vortrag soll einen Einblick in die Nutzung von QGIS für Fragestellungen in der Denkmalwissenschaft bieten. So haben wir durch die Analyse in QGIS in einer Abfolge von Schadenskarten Ungenauigkeiten entdeckt: zuvor kartierte Schäden tauchen in einer späteren Karte nicht auf, was Fragen zur Kartierungsqualität aufwirft. Die Verknüpfung unterschiedlicher thematischer Karten ermöglicht die Überprüfung verschiedener Hypothesen aus dem Bereich Denkmaltheorie: Welche zuvor als historisch wertvoll verzeichneten Gebäude wurden beispielsweise mit welcher Schadenskategorie belegt und wurden diese Gebäude möglicherweise bevorzugt wiederaufgebaut? Wurden Gebäude als total zerstört klassifiziert, wenn sie möglichen Stadtneuplanungen im Weg standen? Die Datenerfassung stellt uns aber auch vor neue Herausforderungen: So wurden auf manchen Karten Gebäudeteile (z.B. Fassaden) getrennt als (un-)zerstört markiert. Wie sollen wir diese erfassen? Ist eine Erhöhung der Granularität auf Gebäudeteile bei vertretbarem Aufwand sinnvoll? Wie gehen wir mit zerstörten und wieder aufgebauten Gebäuden um, vor allem wenn das neue Gebäude das alte nicht exakt ersetzt? Wie ordnen wir hier den zeitlichen Ablauf zu, welche Möglichkeiten bietet QGIS für die Abbildung dieser zeitlichen Verläufe? Die Erfassung der Pläne als GIS-Karte hat zudem Vorteile für die Publikation: Die Copyright-Situation dieser alten Pläne ist sehr unübersichtlich, eine Veröffentlichung häufig nicht möglich. Die GIS-Daten können wir frei nutzen und sowohl als Datensatz als auch als Bild verbreiten und zur Verfügung stellen. __ ¹ https://urbanmetamapping.uni-bamberg.de/ ² https://www.uni-bamberg.de/kdwt/ about this event: https://pretalx.com/fossgis2024/talk/LAFWWV/ </description> <enclosure url="https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-38995-deu-Zerstoerte_Staedte_Historische_Karten_des_Zweiten_Weltkriegs_in_QGIS_analysieren_hd.mp4" length="416284672" type="video/mp4"/> <pubDate>Thu, 21 Mar 2024 15:25:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-38995-deu-Zerstoerte_Staedte_Historische_Karten_des_Zweiten_Weltkriegs_in_QGIS_analysieren_hd.mp4?1711036780</guid> <dc:identifier>fc3aa7ff-ee0c-5fba-bd5d-63d8ba1d9ca3</dc:identifier> <dc:date>2024-03-21T15:25:00+01:00</dc:date> <itunes:author>Anastasia Bauch, Klaus Stein</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>fossgis2024, 38995, 2024, Kartographie und Visualisierung</itunes:keywords> <itunes:summary>Historische thematische Karten auf Basis der gleichen Stadtgrundkarte bilden eine Multi-Layer-Geodatenbank auf Papier.

Die Datenerfassung stellt uns aber auch vor neue Herausforderungen: So wurden auf manchen Karten Gebäudeteile (z.B. Fassaden) getrennt als (un-)zerstört markiert. Wie sollen wir diese erfassen? Ist eine Erhöhung der Granularität auf Gebäudeteile bei vertretbarem Aufwand sinnvoll? Wie gehen wir mit zerstörten und wieder aufgebauten Gebäuden um, vor allem wenn das neue Gebäude das alte nicht exakt ersetzt? Wie ordnen wir hier den zeitlichen Ablauf zu, welche Möglichkeiten bietet QGIS für die Abbildung dieser zeitlichen Verläufe? Die Erfassung der Pläne als GIS-Karte hat zudem Vorteile für die Publikation: Die Copyright-Situation dieser alten Pläne ist sehr unübersichtlich, eine Veröffentlichung häufig nicht möglich. Die GIS-Daten können wir frei nutzen und sowohl als Datensatz als auch als Bild verbreiten und zur Verfügung stellen. __ ¹ https://urbanmetamapping.uni-bamberg.de/ ² https://www.uni-bamberg.de/kdwt/ about this event: https://pretalx.com/fossgis2024/talk/LAFWWV/ </itunes:summary> <itunes:duration>00:26:13</itunes:duration> </item> <item> <title>Virtuelle Erreichbarkeitsanalysen in KomMonitor zur sozialräumlichen Bedarfsplanung (fossgis2024)</title> <link>https://media.ccc.de/v/fossgis2024-38495-virtuelle-erreichbarkeitsanalysen-in-kommonitor-zur-sozialrumlichen-bedarfsplanung</link> <description>Die Open-Source Software KomMonitor bietet Möglichkeiten zur Durchführung von Erreichbarkeitsanalysen auf Basis eines OSM-Netzwerks. Das integrierte Tool zur Berechnung von Erreichbarkeitsisochronen wurde nun um eine virtuelle Szenarienfunktion ergänzt. Diese unterstützt kommunale Fach- und Sozialplaner:innen bei der quantifizierten Analyse der Nahversorgung durch Infrastruktureinrichtungen in kleinräumigen Gebieten. Die webbasierte Open-Source Software KomMonitor ermöglicht ein integriertes GIS-basiertes, raum-zeitliches Monitoring von Geodaten und Statistiken. Im Rahmen kommunaler Fachaufgaben trägt KomMonitor sowohl zur Beantwortung kleinräumlicher Fragestellungen in der Sozialplanung, als auch zur Entscheidungsunterstützung in der Stadtplanung und -entwicklung bei. Ein wesentlicher Bestandteil von KomMonitor sind interaktive Tools zur gemeinsamen interaktiven Analyse und Visualisierung von Geodaten und zeitreihenbasierter Indikatoren. In einer Kartendarstellung sowie verschiedenen statistischen Diagrammen können Zeitreihenanalysen sowie räumliche und inhaltliche Vergleiche durchgeführt werden. Ergänzt wird das Portfolio um Möglichkeiten zur Durchführung von Erreichbarkeitsanalysen. Basierend auf OpenStreetMap-Wegenetzen und der vom Heidelberg Institute for Geoinformation Technology entwickelten Open-Source Software openrouteservice können für selbst gezeichnete Punkte oder systemseitig integrierte Punktdatensätze on-the-fly Erreichbarkeitsisochronen berechnet werden. Für Planungsaufgaben lässt sich so z.B. visuell die Abdeckung des Stadtgebiets durch Infrastruktureinrichtungen innerhalb gewisser Schwellenwerte wie 15-minütiger fußläufiger Erreichbarkeit bestimmen. Insbesondere die integrierte Sozialplanung hat ein besonderes Interesse daran, einen detaillierten Einblick in die Lebenslagen in Sozialräumen zu erhalten, um Angebote zur Steuerung von zielgerichteten, sozialräumlich angepassten und an Lebenslagen und Bedarfen orientierten Maßnahmen zu schaffen. Hierzu gehört zum Einen die Möglichkeit zur quantifizierten Analyse der Bedarfsdeckung in Sozialräumen hinsichtlich bestimmter sozialer Infrastruktureinrichtungen. Zum Anderen ist es notwendig, unterschiedliche Szenarien zur Standortplanung sozialer Einrichtungen hinsichtlich der Auswirkungen auf die soziale Versorgung der Bevölkerung miteinander vergleichen zu können. Um diese Anforderungen zu adressieren, erfolgte eine umfassende Erweiterung der Erreichbarkeitsanalyse in KomMonitor: * Die Ergebnisse aus einer Erreichbarkeitsanalyse können genutzt werden, um quantifizierte Aussagen über die Versorgung der Bevölkerung in räumlichen Gebieten unter Berücksichtigung verschiedener Indikatoren treffen zu können (z. B. Anzahl der im Einzugsbereich lebenden Menschen eines POIs). * Die Erreichbarkeitsanalyse wurde um Funktionen ergänzt, die es erlauben, POIs interaktiv zu planen und für die Analyse von Erreichbarkeiten zu nutzen. * Erreichbarkeitsanalysen lassen sich als “Virtuelle Szenarien” anlegen und untereinander für verschiedene Planungsgrundlagen vergleichen. * Ergebnisse virtueller Planungsszenarien können in Template-basierte Reports eingebunden werden, um diese über PDF-Exports für Präsentationszwecke verfügbar zu machen. Der vorliegende Beitrag möchte das Konzept der virtuellen Szenarienfunktion in KomMonitor anhand praktischer Beispiele vorstellen. Hierzu werden die Funktionsweise des Tools sowie Praxisbezogene Anwendungsfälle aus der integrierten Sozialplanung präsentiert. about this event: https://pretalx.com/fossgis2024/talk/BKXEEG/ </description> <enclosure url="https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-38495-deu-Virtuelle_Erreichbarkeitsanalysen_in_KomMonitor_zur_sozialraeumlichen_Bedarfsplanung_hd.mp4" length="214958080" type="video/mp4"/> <pubDate>Thu, 21 Mar 2024 09:35:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-38495-deu-Virtuelle_Erreichbarkeitsanalysen_in_KomMonitor_zur_sozialraeumlichen_Bedarfsplanung_hd.mp4?1711015416</guid> <dc:identifier>f3168685-2208-5841-b115-1f654b458bb2</dc:identifier> <dc:date>2024-03-21T09:35:00+01:00</dc:date> <itunes:author>Sebastian Drost, Isabell Rohling, Christian Danowski-Buhren</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>fossgis2024, 38495, 2024, Raum-zeitliche Analysen und Modelle</itunes:keywords> <itunes:summary>Die Open-Source Software KomMonitor bietet Möglichkeiten zur Durchführung von Erreichbarkeitsanalysen auf Basis eines OSM-Netzwerks.

Dabei zeigen wir insbesondere Probleme und Lösungsansätze hinsichtlich der Topologie und Geometrie von Räumen, Raumgrenzen und -verbindungen zwischen Räumen innerhalb eines Geschosses. Typische Funktionen, die GIS für urbane Außenräume erfüllt, wie die Lokalisierung von Zielen und Barrieren sowie die Navigation dahin oder darum herum, sind auch im Inneren von Gebäuden relevant. Darum werden georäumliche Datenbanken, Karten- und Routingservices für Innenraumanwendungen angereichert und erweitert, z.B. in OpenStreetMap mit SIT. Um den damit verbundenen Aufwand zu reduzieren und Daten mit höherer Qualität zu erzeugen, untersuchen wir, wie Innenraumdaten u.a. für OSM automatisiert aus digitalen Gebäudemodellen im Format IFC abgeleitet werden können. Diese Gebäudemodelle liegen im Rahmen der Planung von Neubauten regelmäßig vor und werden zunehmend auch im Zuge von Umbaumaßnahmen für Bestandsgebäude angefertigt. Dafür implementieren wir quelloffene Konvertierungsroutinen (https://bauinformatik.github.io/levelout). Unsere bisherigen Ergebnisse beschränken sich auf grundlegende Elemente und unterliegen gezielten Einschränkungen. Beispielsweise betrachten wir keine vertikalen Verbindungen zwischen Geschossen, sogenannte vertikale Erschließung, wie Treppenhäuser und Aufzüge. Innerhalb eines einzelnen Geschosses extrahieren wir eine topologische Struktur aus Räumen, raumbegrenzenden Elementen und den die Raumbegrenzungen durchbrechenden Verbindungen zwischen den Räumen - das heißt Räume, Wände und Türen bzw. Öffnungen - sowie die zugehörigen Geometrien. Sowohl die Topologie wie auch die Geometrie können in IFC in verschiedenen Formen vorliegen. Wir setzen für unsere aktuelle Implementierung eine explizite Topologie in den IFC-Daten voraus, beziehen die Geometrie der Raumbegrenzungen jedoch aus den regelmäßig enthaltenen 3D-Festkörpergeometrien für Räume, Wände und Öffnungen. Damit erhalten wir ein "dickwandiges" Geometriemodell, bei dem aus dem Volumen der Wände zwei Segmente der Raumbegrenzungen mit dem Abstand der Wanddicke resultieren, die nicht mehr topologisch Verbunden sind. Die in OSM übliche implizite Repräsentation der Topologie über die Geometrie (durch gemeinsame Polygonsegmente) ist auf dieser Basis nicht möglich und somit auch keine Ableitung von Routinggraph en. In diesem Paper stellen wir verschiedene geometrische und topologische Repräsentationsmöglichkeiten in IFC vor, stellen sie den Modellierungsprinzipien von OSM gegenüber und diskutieren ihr Potential der für die automatische Ableitung. Wir zeigen eine gegenüber der ersten Proof-of-Concept-Implementierung deutlich verbesserten Algorithmus und die damit erzeugte OSM-Struktur, die weiterhin auf den "dickwandigen" Modell beruht, aber die Oberflächen in den Öffnungsbereichen zu einer "dünnwandigen" Raumgrenze verschmilzt und damit die Voraussetzungen erfüllt, OSM-Routinggraphen abzuleiten. Weiterhin stellen wir eine alternative Konvertierungsmöglichkeit vor, die auf der 2D-Achsenrepräsentation von Wänden basiert und demonstrieren ihre Vor- und Nachteile. Wir fassen auch den Stand der Wissenschaft und Technik, insbesondere zu Raumgeometrie und -topologie sowie Space Boundaries in digitalen Gebäudemodellen im IFC-Format und in anderen Formaten wie IndoorGML zusammen. about this event: https://pretalx.com/fossgis2024/talk/LXGXQJ/ </description> <enclosure url="https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-38014-deu-Ableitung_von_korrekten_OSM-Raeumen_-Waenden_und_-Tueren_aus_IFC-Gebaeudemodellen_hd.mp4" length="304087040" type="video/mp4"/> <pubDate>Thu, 21 Mar 2024 11:45:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-38014-deu-Ableitung_von_korrekten_OSM-Raeumen_-Waenden_und_-Tueren_aus_IFC-Gebaeudemodellen_hd.mp4?1711024301</guid> <dc:identifier>3a7f4694-da30-5b89-b187-51df2536c2f7</dc:identifier> <dc:date>2024-03-21T11:45:00+01:00</dc:date> <itunes:author>Helga Tauscher</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>fossgis2024, 38014, 2024, OpenStreetMap</itunes:keywords> <itunes:summary>In diesem Paper diskutieren wir die Ableitung von Inneraumdaten im Format OSM-SIT aus digitalen Gebäubemodellen im Format IFC.

Wir zeigen eine gegenüber der ersten Proof-of-Concept-Implementierung deutlich verbesserten Algorithmus und die damit erzeugte OSM-Struktur, die weiterhin auf den "dickwandigen" Modell beruht, aber die Oberflächen in den Öffnungsbereichen zu einer "dünnwandigen" Raumgrenze verschmilzt und damit die Voraussetzungen erfüllt, OSM-Routinggraphen abzuleiten. Weiterhin stellen wir eine alternative Konvertierungsmöglichkeit vor, die auf der 2D-Achsenrepräsentation von Wänden basiert und demonstrieren ihre Vor- und Nachteile. Wir fassen auch den Stand der Wissenschaft und Technik, insbesondere zu Raumgeometrie und -topologie sowie Space Boundaries in digitalen Gebäudemodellen im IFC-Format und in anderen Formaten wie IndoorGML zusammen. about this event: https://pretalx.com/fossgis2024/talk/LXGXQJ/ </itunes:summary> <itunes:duration>00:28:50</itunes:duration> </item> <item> <title>Verarbeitung hochaufgelöster Umweltdaten auf Basis von OGC API Processes (fossgis2024)</title> <link>https://media.ccc.de/v/fossgis2024-38785-verarbeitung-hochaufgelster-umweltdaten-auf-basis-von-ogc-api-processes</link> <description>Das Forschungsprojekt KLIPS hat zum Ziel hochaufgelöste Umweltdaten in nutzbarer Form zur Verfügung zu stellen, um eine inhaltliche Interpretation für Gemeinden und Städte zu ermöglichen.

Der Vortrag stellt die Verarbeitung solcher Daten u.a. mit Hilfe von OGC API Processes und pygeoapi vor. Innerstädtische Hitzeinseln gehören zu den großen Herausforderungen, denen Städte in Folge des Klimawandels gegenüberstehen. Im Forschungsprojekt KLIPS (gefördert vom Deutschen Bundesministerium für Digitales und Verkehr (BMDV)) wird mit Hilfe eines ausgedehnten Sensornetzwerks in zwei Pilotstädten, sowie KI-basierten Methoden zur Lokalisierung von Hitzeinseln, eine große Menge hochaufgelöster Umweltdaten generiert. Um solche Daten effektiv nutzen zu können, müssen sie den Entscheidungsträgern und der Öffentlichkeit in aufbereiteter und praktisch nutzbarer Form zur Verfügung gestellt werden. terrestris und meggsimum haben in diesem Kontext eine Geodateninfrastruktur (GDI) entworfen, welche die Daten empfängt, aufbereitet, und auf Basis von OGC-Standards (WMS, WFS) publiziert. Hier kommen OGC API Processes und die Server-Software pygeoapi für die Prozessierung zum Einsatz. Die einzelnen Komponenten wurden mittels Docker als Microservices erstellt.

Der Vortrag beleuchtet das verwendete Setup um eine Vielzahl von verschiedenen Projekten zu veröffentlichen und erläutert Vor- und Nachteile im Vergleich zu anderen gängigen Lösungen wie GeoServer. Dieser Vortrag stellt die Funktionalitäten und die Integration des QGIS Servers dar. Eine besondere Stärke des QGIS Servers liegt in seiner Fähigkeit, Geodaten im Web so darzustellen, wie sie auch im QGIS Desktop sichtbar sind. Dies ist vor allem relevant, wenn eine umfangreiche Auswahl an verschiedenen Kartenstilen auf Basis von QGIS vorhanden ist. Die Konfiguration des QGIS Servers erfolgt ausschließlich über ein QGIS-Projekt, was die Einrichtung recht komfortabel gestaltet. Zu beachten ist jedoch, dass derzeit keine automatisierten Einstellungen beispielsweise per API möglich sind. Der QGIS Server unterstützt verschiedene OGC-Standards, darunter WMS (Web Map Service), WFS (Web Feature Service), WCS (Web Coverage Service) und WMTS (Web Map Tile Service). Darüber hinaus bietet er eine prototypische Implementierung von OAF (OGC API - Features) an und integriert viele Funktionen von QGIS, einschließlich des Exports von im Desktop vorbereiteten Karten. Im Rahmen dieses Vortrags wird auch die Installation des QGIS Servers mithilfe von Docker behandelt. Des Weiteren wird die Integration des QGIS Servers in Middleware-Lösungen erörtert, um die Nutzung in komplexen GIS-Umgebungen zu ermöglichen. Ein weiterer Schwerpunkt wird auf die Konfiguration von veröffentlichten Layern und der Auswahl der veröffentlichten Attribute gelegt.

Grundlage für diese App sind OSM-Daten zu Barrieren und Eigenschaften von Haltestellen im Öffentlichen Personenverkehr. Dieser Vortrag ist eine Fortführung zu unserem Beitrag von der FOSSGIS 2022 [1], in dem präsentiert wurde, wie im Projekt OPENER next mit Hilfe der App OpenStop jene Daten er-fasst werden. Solange der Öffentliche Personenverkehr noch nicht komplett barrierefrei ausgebaut oder zumindest beschildert ist, ist Indoor-Navigation ein wichtiger Bestandteil einer barrierefreien Reisekette. Bahnhofsgebäude können mitunter komplex sein und vor allem bei weiter entfernten Reisen auch unbekannt. Gerade Menschen mit Mobilitätseinschränkungen stellt dies vor Herausforderungen. Der Vortrag präsentiert, wie auf Basis von in OSM hinterlegten Daten zu Eigenschaften und Barrieren von Haltestellen des Öffentlichen Personenverkehr eine Indoor-Navigations-App realisiert wird. Die App selbst sowie die ausgegebenen Routen sollen dabei barrierefrei sein. Ein wichtiger Aspekt des Vortrages ist daher die visuelle, akustische und haptische Ausgabe des Routings abhängig von verschiedenen Einschränkungen der Nutzer. Des Weiteren wird darauf eingegangen, wie MOTIS bzw. Per Pedes [2] von der TU Darmstadt dazu verwendet wird, ein barrierefreies Routing für verschiedene Nutzergruppen zu generieren.

Für diese Szenen wurden zwei Vegetationsindizes berechnet, sowie mittels zonaler Statistiken der Median dieser Vegetationsindizes pro Waldgebiet. Für die automatische Waldüberwachung wurden die Veränderungen der Indizes berechnet, sowie starke Veränderungen (z.B. durch Waldrodungen) mittels eines Grenzwerts als solche gekennzeichnet. Die umfangreichen Sentinel-Archive bieten ein enormes Potenzial für die automatische Waldüberwachung. Dieses Potenzial werden innerhalb eines längerfristigen Projektes für das irische staatliche Forstwirtschaftsunternehmen Coillte analysiert. Für die Prozessierung werden Sentinel-2 (L2A) Szenen über Irland auf zunächst vierteljährlicher Basis (Zeitraum anpassbar) ausgewählt. Dabei wird die Wolkenbedeckung bei der Auswahl der Szenen berücksichtigt. Innerhalb der Machbarkeitsstudie war der Analyse-zeitraum auf Juli 2022 bis März 2023 beschränkt, im weiteren Projektverlauf wird dies auf weitere zurückliegende Jahre ausgedehnt sowie in der Zukunft quartalsweise betrachtet. Für die jeweiligen Szenen (eine pro Quartal) werden zwei Vegetationsindizes berechnet: der Normalized Difference Vegetation Index (NDVI) und der Enhanced Vegetation Index (EVI). Pro Waldgebiet wird dann mittels zonaler Statistiken der NDVI und EVI Median berechnet. Mit Hilfe der zonalen Statistiken kann dann eine Veränderungsdetektion ausgeführt werden. Dafür werden Differenzen von benachbarten Zeitpunkten gebildet. Wenn es keinen direkt benachbarten Zeitpunkt mit einer Messung (bzw. abgeleiteten Index Median) gibt, wird der nächst vorige verfügbare Zeitpunkt für die Veränderungsberechnung genutzt. Damit kann der Mangel an Daten durch die in Irland recht häufig auftretende Wolkenbedeckung reduziert werden. Um starke Veränderungen einzelner Waldgebiete automatisch zu Erkennen, werden die im vorigen Schritt berechneten Differenzen mit einem anpassbaren Schwellenwert verglichen. Wird dieser Schwellenwert überstiegen, wird das Waldpolygon als signifikant verändert gekennzeichnet. Dieses Ergebnis bildet die Basis für weitere waldwirtschaftliche Entscheidungen. about this event: https://pretalx.com/fossgis2024/talk/QJSTCF/ </description> <enclosure url="https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-39035-deu-Monitoring_von_Waldgebieten_mit_Hilfe_von_Sentinel-2_abgeleiteten_Vegetationsindizes_hd.mp4" length="326107136" type="video/mp4"/> <pubDate>Wed, 20 Mar 2024 17:05:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-39035-deu-Monitoring_von_Waldgebieten_mit_Hilfe_von_Sentinel-2_abgeleiteten_Vegetationsindizes_hd.mp4?1711004775</guid> <dc:identifier>07a72c22-74f5-55fd-8180-bff864b869ce</dc:identifier> <dc:date>2024-03-20T17:05:00+01:00</dc:date> <itunes:author>Markus Eichhorn</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>fossgis2024, 39035, 2024, Raum-zeitliche Analysen und Modelle</itunes:keywords> <itunes:summary>Innerhalb des Projektes werden Sentinel-2 L2A-Szenen über Irland ausgewählt.

Mit like ließen sich schon Platzhalter verwenden und natürlich konnten Flächen und Strecken ermittelt werden. Viel mehr gab es zunächst nicht. Heute soll schon mancher Einsteiger nach dem ersten Anblick der Funktionsvielfalt laut schreiend davon gelaufen sein. Das ist schade, denn der Ausdruckseditor bringt aussergewöhnliche Möglichkeiten mit und ist inzwischen viel mehr als ein Abfrageeditor für den einzelnen Layer. Thema der Livedemo sind Funktionen, die sehr nützlich sind, deren Einsatzzweck sich aber vielen Anwender/innen nicht sofort erschließt bzw. deren Anwendung als sperrig gilt: Case und if für bedingte Fragestellungen einsetzen, um z.B. die Schriftgröße von Ortnamen nach der Einwohnerzahl steuern. Mit coalesce(), concat() etc. nie mehr über NULL-Werte stolpern. Auf externe Layer zugreifen: TabellenJoins mit attribute() und get_feature()simulieren sowie eins zu mehrfach-Beziehungen mit aggregate() auswerten. Dynamische räumliche Abfragen mit aggregate(...intersects($geometry,@parent(geometry) und overlay() verwirklichen. Damit lassen sich z.B. Anzahl und Leistung der Windanlagen aus einem Punktlayer in den Gemeinde-Polygonen dynamisch mitführen, ohne neue Layer über die Geoverarbeitung zu produzieren . Abfragen mit aggregate() und Overlay() ergeben Felder mit vielen Werten, die Listenfelder oder Arrays. Was hat es mit diesen Arrays auf sich? Der gezielte Zugriff auf einzelne Werte ist möglich. Mit den zugehörigen Funktionen lässt sich sortieren, auswerten und für jeden einzelnen Wert, wie in einer Schleife, Berechnungen und Abfragen durchführen. Werden die Ausdrücke zu kompliziert, lassen sich Komplexe Teilausdrücke mit with_variabel() als Variable widerverwenden,so dass auch komplexe Ausdrücke lesbar bleiben. Mit den Geometriefunktionen beschränkt sich QGIS nicht auf die Flächenberechnung. Pufferflächen, Verschneidungen und viele andere Geometrieoperationen lassen sich in Berechnungen integrieren. Die Suchen mit Platzhaltern über den like-Operator und die Auswahl von Teil-Zeichenketten mit substr(), strpos() ist vielen QGIS-Nutzern ein Begriff.

Ein eigenes DecSecOps-Team entwickelt und betreibt seit über 4 Jahren eine SaaS-Anwendung zur Unterstützung der Katasterämter. Diese “KI-Gebäudeerkennung” hilft beim Aktualisieren der ALKIS-Daten. Kann sie auch beim Aktualisieren der OSM-Gebäude helfen? Das Landesamt für Geoinformation und Landesvermessung Niedersachsen (LGLN) hat in den letzten Jahren über 10 eigene, agile DevSecOps-Teams aufgebaut. Eines der Teams entwickelt und betreibt “lernende GeoServices”. Diese SaaS-Anwendungen nutzen Fernerkundungsdaten und Machine-Learning-Modelle, um automatisiert Geoinformationen zu gewinnen. Die erste produktive Anwendung ist eine “KI-Gebäudeerkennung”. Diese ersetzt das visuelle Durchmustern der Digitalen Orthophotos (DOP) durch Bearbeitende in den Katasterämtern durch automatisiert erzeugte Hinweise auf neue Gebäude, bauliche Veränderungen oder Abrisse. Auch Niedersachsen muss die Hausumringe der ALKIS-Daten spätestens am 9.6.2024 mit einer Open-Data-Lizenz kostenlos zum Download und per API bereitstellen. Dadurch entstehen neue Nutzungsmöglichkeiten und die Anforderungen an die Aktualität der Daten werden weiter steigen. Durch den Einsatz KI-unterstützter Fachanwendungen möchten wir die hohen Ansprüche an unsere amtlichen Geodaten in Zukunft noch besser erfüllen. Dabei gilt, wie bei allen Eigenentwicklungen des LGLN, Open Source First. Neben den Ergebnissen der KI-Gebäudeerkennung werden daher in Zukunft auch Trainingsdaten, KI-Modelle und sämtlicher Source Code mit freier Lizenz veröffentlicht. Grundsätzlich möchten wir beim Einsatz von “Künstlicher Intelligenz” transparent sein und beleuchten im Vortrag auch die Herausforderungen und Erfolge bei der Entwicklung und dem Betrieb einer KI-Anwendung in der öffentlichen Verwaltung. about this event: https://pretalx.com/fossgis2024/talk/JAS9RR/ </description> <enclosure url="https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-39041-deu-KI-Gebaeudeerkennung_-_Deep-Learning-Modelle_zur_Aktualisierung_der_ALKIS-Gebaeude_hd.mp4" length="250609664" type="video/mp4"/> <pubDate>Thu, 21 Mar 2024 14:15:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-39041-deu-KI-Gebaeudeerkennung_-_Deep-Learning-Modelle_zur_Aktualisierung_der_ALKIS-Gebaeude_hd.mp4?1711032680</guid> <dc:identifier>990ea2fa-4f63-52b0-9ee4-5ee3221d2774</dc:identifier> <dc:date>2024-03-21T14:15:00+01:00</dc:date> <itunes:author>Jonas Bostelmann, Birger Giesen, Valentina Schmidt</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>fossgis2024, 39041, 2024, Daten, Datenbanken und Datenprozessierung</itunes:keywords> <itunes:summary>Beim Einsatz “Künstlicher Intelligenz” zur Erkennung von Gebäuden in Luftbildern setzt die Landesvermessung Niedersachsen (LGLN) auf Open Source Software und selbst trainierte Deep-Learning-Modelle.

Als Beitrag zu einer optimalen staatlichen Vorsorge erstellt das Bundesamt für Kartographie und Geodäsie (BKG) eine bundesweite und einheitliche Hinweiskarte zu Starkregengefahren. Diese wird bis Ende 2025 sukzessive erstellt und Entscheidungsträgern, dem Katastrophenschutz sowie der gesamten Öffentlichkeit als OpenData frei zugänglich gemacht. Die bei Starkregenereignissen auftretenden Niederschlagsmengen können in kürzester Zeit so hoch ausfallen, dass es auch abseits von Gewässern zu katastrophalen Überflutungen und in der Folge zu erheblichen Personen- und Sachschäden kommt. Zum bestmöglichen Schutz müssen relevante Informationen für präventive Maßnahmen und für ein wirksames Katastrophenmanagement frei verfügbar mit einfacher Zugriffsmöglichkeit vorliegen. Unerlässlich sind dabei Informationen zur Lage und zur potentiellen Intensität der Gefahren. Hierbei haben Geodaten, wie etwa Digitale Geländemodelle, Bebauungsdaten oder hydrologische Bauwerksinformationen, eine entscheidende Bedeutung. Mittels einer hydrodynamischen Abflusssimulation lassen sich daraus Überflutungsszenarien für verschiedene Niederschlagsereignisse erstellen, die Hinweise über Risiken von Starkregenereignissen liefern.

Bei interdisziplinärer Zusammenarbeit ist dieser Aspekt umso wichtiger. In diesem Paper werden fünf data-driven interdisziplinäre Use-Cases für den Umgang mit und die Modellierung von vagen und unsicheren Georeferenzen aus dem Bereich der Archäologie und Geowissenschaften vorgestellt. # Einleitung Geodätinnen und Geodäten wissen, dass jede Bestimmung einer Länge, Winkel, bzw. eine Koordinate mit Unsicherheiten und/oder statistischen Kenngrößen wie Standardabweichungen, 3-Sigma-Regel etc. belegt ist. Insbesondere bei der Bereitstellung von Open Data nach den FAIR-Prinzipien [1] (Findable, Accessible, Interoperable und Reusable) zur bestmöglichen Offenheit und Transparenz ist die Angabe von Unsicherheiten und Zweifeln für den Nachnutzenden von enormer Bedeutung. Bei interdisziplinärer Zusammenarbeit ist dieser Aspekt umso wichtiger. Insbesondere in den Geistes- und Kulturwissenschaften (Humanities / Cultural Heritage) und auch Geowissenschaften (wie z.B. Geologie) spielen Geodaten eine große Rolle. Georeferenzierungen sind Teil der täglichen Arbeit und stellen ein Herausforderung bei der Bereitstellung von Open Geodata nach den FAIR-Prinzipien dar. Archäologische und geowissenschaftliche Forschung muss bei der Datenmodellierung mit Zweifeln wie Fuzzyness und Mehrdeutigkeiten umgehen. Dies geschieht insbesondere bei der Georeferenzierung [2;3]. Um jedoch reproduzierbare und verständliche Daten für die Wiederverwendung zu schaffen und gleichzeitig die Datenqualität archäologischer Daten zu gewährleisten, müssen diese Zweifel und Unklarheiten offengelegt werden [4]. Dies ist auch für die FAIRifizierung von Daten wichtig, die ein großer Teil der Nationalen Forschungsdateninfrastruktur (NFDI) ist [5;6]. In diesem Kontext müssen insbesondere Vagheiten und Unsicherheiten für die Arbeit mit und Bereitstellung von Geodaten modelliert werden [7-9]. Für die Verknüpfung von Daten und die FAIRifizierung ist jedoch die von Berners-Lee [10] vorgeschlagene graphbasierte Modellierung als Linked Open Data (LOD) die Methode und Technik der Wahl. Aufgrund der großen Vielfalt der Forschungsbereiche ist eine interdisziplinäre, allgemein verständliche Modellierung von Unsicherheiten und Vagheiten in Geodaten eine große Herausforderung. In diesem Paper werden fünf data-driven interdisziplinäre Use-Cases für den Umgang mit und die Modellierung von vagen und unsicheren Georeferenzen (am Beispiel von Fundstellen) auf der Grundlage von Literatur als LOD aus dem Bereich der Archäologie und Geowissenschaften vorgestellt. Die Anwendungsfälle implementieren drei Modellierungsstrategien [11] unter Verwendung von Wikidata, Linked Open Data sowie einer Ontologie, modelliert in OWL [12] und Wikibase [13] und nehmen zudem Möglichkeiten in Open Street Map unter die Lupe. # Use Cases ## Use Case A Ogham-Steine sind Monolithen mit der frühmittelalterlichen irischen Ogham-Primitivschrift, die vor allem auf der Insel Irland und im westlichen Teil Großbritanniens zwischen dem 4. und 9 Jhd. n. Chr. errichtet wurden. Die meisten Steine befinden sich nicht mehr an ihrem ursprünglichen Standort, was für die kartografische Erfassung wichtig ist und die Bestimmung ihrer ursprünglichen Funktion erschwert [14]. Ogham-Steinfunde werden in verschiedenen Katalogen wie Büchern (z. B. 14-16), Online-Datenbanken (z. B. das CISP-Projekt) oder Online-Repositorien (z. B. Ogham in 3D) erwähnt. Diese Quellen liefern Informationen in unterschiedlicher Granularität: Townlands, Beschreibungen und Koordinaten in WGS84/GPS oder irischen GRID-Referenzen. Zudem werden ganze Biographien von Geo-Locations dort erfasst. Wie könnten diese Ungenauigkeiten und Unsicherheiten in Community-Hubs wie Wikidata oder Open Street Map abgebildet werden? Ein Beispiel hierfür ist CIIC 81, der im Stone Corridor des University College Cork (UCC) steht und mit Hilfe von WIkidata [17] und Open Street Map modelliert wurde, vgl. auch Wikidata Q106680733 [18] und OSM Node 11071361392 [19]. ## Use Case B Die Dissertation von S. Baars beschäftigt sich mit der Silbermünzprägung von Kroton, einer achäischen Kolonie in Süditalien, vom 6. bis 3. Jh. v. Chr. Dabei kommen verschiedene numismatische Methoden zum Einsatz, darunter auch die der Hortfundanalyse. Sämtliche Fundorte der untersuchten Horte sind nicht exakt georeferenziert (z. B. anhand der Dokumentation von Grabungsberichten). Die ermittelten Fundorte sind aus der Literatur abgeleitet und weisen unterschiedliche Präzisionsgrade hinsichtlich der geografischen Lage auf. Eine recht genaue Angabe bietet z. B. der Hortfund von "Tarent 1938" (IGCH 1902) in der "via Oberdan" in Tarent. Hinweise auf eine Verortung des Fundes im modernen und/oder antiken Stadtkerne liefern z. B. "Paestum 1937" (IGCH 1925) oder "Strongoli 1955" (IGCH 1885; in der Gegend der antiken Stadt Petelia). Teils sind lediglich Hinweise auf größere Regionen vorhanden, z. B. wurden Hortfunde im Jahr 1864 in "Kalabrien" (IGCH 1873) oder 1964 in "Süditalien" (IGCH 1894) gefunden oder stammen von der "Ionischen Küste” (IGCH 1916). Die Modellierung dieser Fundorte wurde mittels RDF und Wikibase durchgeführt. Ein Beispiel hierfür ist der Fundort “Fiume Esaro 1967 (gennaio)”, der die fuzzy-sl Wikibase ID Q67 [20] und URI site_3003 [21] führt. ## Use Case C Ein Teil der Dissertation von F. Schenk befasst sich mit den Nachweisen des Ascheregens des Campanian Ignimbrite (CI) in Mitteleuropa; ein trachytischer Tuff aus einem spätpleistozänen vulkanischen Ereignis [22;23], der aus der Region Kampanien (Italien) stammt. Vor etwa 40.000 Jahren fand der größte Ausbruch des CI in den Phlegräischen Feldern statt. In diesen Tagen ist dies wieder von erhöhtem Interesse, da ein weiterer Ausbruch des Supervulkans bevorstehen könnte [24]. Nach dem Ausbruch bedeckten massive Glasablagerungen aus dem CI-Ausbruch große Teile des osteuropäischen Kontinents; vulkanisches Material des CI findet sich häufig in isolierten Wasserscheiden und Tälern. Diese Fundorte sind in mehreren Papern festgehalten, z.B. (a) genaue Koordinaten, z.B. "[...] Lago Grande di Monticchio in Süditalien (40°56N, 15°35′E)" [25], (b) Verweise auf Städte, z. B. Neapel [26] (c) Verweise auf Regionen, z. B. Altopiano delle Murge [27] oder (d) Verweise auf Höhlen und archäologische Stätten, z.B. die Crvena Stiljena-Höhle in Montenegro [28]. Dabei stellt sich die Frage wie diese verschiedenen Granularitäten von Fundorten modelliert und auf einen WKT-Punkt vereinfacht werden? Ist die Verwendung von “Google Maps” oder “geohack by toolforge” ausreichend? Diese Modellierungen wurden mittels RDF und Wikibase durchgeführt. Ein Beispiel hierfür ist der Fundort in der “Crvena Stiljena-Höhle”, der die URI cisite_51 [29] führt. ## Use Case D Insbesondere in Münzfund-Datenbanken wie z.B. Antike Fundmünzen in Europa (AFE) werden Fund-Koordinaten hinterlegt. Zu diesem Fundort kann angegeben werden, ob die Koordinaten präzise sind oder auch nicht. Ein Fundort kann hier z.B. ein Gräberfeld, eine Grabungsstelle oder ein Einzelfund eines Sondengängers sein. Alle Fundmünzen mit allen Details wie bei einer Grabung einzugeben ist weder umsetzbar (da die Details oft fehlen) noch zielführend, da die Eingabe zu viel Zeit und die Oberfläche zu unübersichtlich werden würde. Um die Fundorte vor privaten Sondengängern zu schützen, werden Fund-Koordinaten jedoch durch AFE nur auf einer höheren Ebene (Place) veröffentlicht. Hierbei wird möglichst mit dem einem Ortsverzeichnis, hier: iDAI.gazetteer [30], verbunden. Dies kann jedoch zu Problemen führen, wenn Fundmünzen in verschiedenen Systemen eingetragen sind. Da aber das Vorgehen zum Verschleiern der Fund-Koordinaten über die Systeme nicht vereinheitlicht wurde, können diese nur bedingt genutzt werden, um Duplikate zu identifizieren. Werden diese Duplikate nicht erkannt, kann dies zu fehlerhaften Auswertungen von Daten aus verschiedenen Quellen führen. ## Use Case E Die Münzstätte einer Münze ist nicht immer eindeutig, man hat nicht immer einen Namen dazu und weiß auch nicht, wo diese lag. Wenn man jedoch Münzen einheitlich einer soche Münzstätte zuordnen möchte, wird dies in nomisma.org durch sogenannte "uncertain mints" verwirklicht. Man weiß also nicht, wo die Mints waren und ob diese nicht vielleicht auch eine andere benannte Mint sein könnten. Nomisma listet bei der Suche nach “uncertain” für Münzstätten immerhin 232 Treffer auf, z.B. [Uncertain Mint 129](http://nomisma.org/id/uncertain_129_sco). In der RDF-Modellierung zu dieser wird die Unsicherheit noch nicht mit modelliert. Daher wurden in zwei Masterarbeiten [31;32] acht Möglichkeiten untersucht, wie Unsicherheiten in RDF modelliert werden können. # Referenzen [1] https://doi.org/10.1038/sdata.2016.18 [2] https://www.adwmainz.de/fileadmin/user_upload/digitale-akademie/graphentechnologien/Bruhn-Unold-Unsicherheit_Graphdatenbanken.pdf [3] https://doi.org/10.5281/zenodo.6380914 [4] http://dx.doi.org/10.15496/publikation-87762 [5] https://doi.org/10.5281/zenodo.5654897 [6] https://doi.org/10.5281/zenodo.5849841 [7] https://zfdg.de/sb004_004 [8] https://doi.org/10.1023/A:1016740830286 [9] https://doi.org/10.5281/zenodo.3252392 [10] https://www.w3.org/DesignIssues/LinkedData.html [11] https://codeberg.org/ResearchSquirrels/fuzzy-sl [12] https://github.com/research-Squirrel-Engineers/fuzzy-sl-ontology [13] https://fuzzy-sl.wikibase.cloud/ [14] Macalister, RAS.

Mapbender bietet die Möglichkeit eine unbegrenzte Anzahl von Anwendungen zu erzeugen. Die Anwendungen können nach Belieben aufgebaut und mit Kartendiensten ausgestattet werden. Es können leicht individuelle Suchen und Datenerfassung aufgebaut werden. Dies erfolgt alles ohne Code schreiben zu müssen. Es wird der Blick in die Administration gerichtet und die Konfiguration von Anwendungen praktisch demonstriert. Dabei wird der Fokus auf die Version 4.0 gesetzt und die Neuerungen und Änderungen werden vorgestellt. **Was ist Mapbender?** Ist eine Software zur Erstellung von webbasierten Kartenanwendungen. Mapbender bietet mächtige Werkzeuge zur Erfassung, Anzeige, Bearbeitung und Verwaltung von Geodaten. Wie ein Content-Management-System (CMS) für Geodaten und Geodienste verfügt Mapbender über eine komfortable webbasierte Oberfläche, um individuelle Anwendungen zu erstellen. Mit nur einer Installation können beliebig viele Anwendungen angelegt und individuell gestaltet werden. Darüber hinaus verfügt Mapbender über eine Benutzerverwaltung und ein Rechtemanagement, um den Zugriff auf Anwendungen zu steuern.

Mapbender bietet die Möglichkeit eine unbegrenzte Anzahl von Anwendungen zu erzeugen. Die Anwendungen können nach Belieben aufgebaut und mit Kartendiensten ausgestattet werden. Es können leicht individuelle Suchen und Datenerfassung aufgebaut werden. Dies erfolgt alles ohne Code schreiben zu müssen. Es wird der Blick in die Administration gerichtet und die Konfiguration von Anwendungen praktisch demonstriert. Dabei wird der Fokus auf die Version 4.0 gesetzt und die Neuerungen und Änderungen werden vorgestellt. **Was ist Mapbender?** Ist eine Software zur Erstellung von webbasierten Kartenanwendungen. Mapbender bietet mächtige Werkzeuge zur Erfassung, Anzeige, Bearbeitung und Verwaltung von Geodaten. Wie ein Content-Management-System (CMS) für Geodaten und Geodienste verfügt Mapbender über eine komfortable webbasierte Oberfläche, um individuelle Anwendungen zu erstellen. Mit nur einer Installation können beliebig viele Anwendungen angelegt und individuell gestaltet werden. Darüber hinaus verfügt Mapbender über eine Benutzerverwaltung und ein Rechtemanagement, um den Zugriff auf Anwendungen zu steuern. Das flexible Rechtemanagement, die Verwaltung von Datenquellen und Kartendiensten, sowie Designanpassung der Oberfläche bieten bieten eine große Gestaltungsfreiheit beim Aufbau von Anwendungen. Anhand einer praktischen Vorstellung lernen Sie Mapbender kennen.

Es werden die einzelnen Schritte des Workflows sowie die Einsatzmöglichkeiten von Machine Learning im Detail erläutert. Der Standard XPlanung sieht eine Umsetzung aller in Deutschland erstellten Planwerke in das Datenaustauschformat XPlanGML vor. Die Frist zur Umsetzung bestehender Planwerke endete im Februar 2023, trotzdem liegen viele Planwerke noch immer nicht als XPlanGML vor. Die einfachste Bereitstellung von XPlanGML ist das sog. Raster-Umring-Szenario, bei dem das Planwerk als Rasterdatei vorliegt und der Geltungsbereich durch einen Vektorumring dargestellt werden muss. In diesem Vortrag wird ein methodischer Ansatz mit Machine Learning zur automatisierten Erstellung von XPlanGML im Raster-Umring-Szenario vorgestellt. Im Vordergrund steht dabei die Erstellung einer georeferenzierten und zugeschnittenen Rasterdatei, welche aus einem einfachen Scan mittels Machine Learning erstellt wird. Die einzelnen Schritte zur Erstellung einer XPlanGML im Raster-Umring-Szenario werden demnach im Detail vorgestellt und gezeigt, wo die Nutzung von Machine Learning möglich ist. Die Arbeiten zu diesem Thema sind noch nicht abgeschlossen und werden aktuell im Rahmen einer Masterarbeit durchgeführt. Die Fragestellung soll dabei mit verschiedenen Open-Source Software-Anwendungen gelöst werden und befasst sich ausschließlich mit Bebauungsplänen. about this event: https://pretalx.com/fossgis2024/talk/KLCZXW/ </description> <enclosure url="https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-38908-deu-Einsatz_von_Machine_Learning_zur_Erstellung_von_XPlanGML_hd.mp4" length="258998272" type="video/mp4"/> <pubDate>Wed, 20 Mar 2024 15:25:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-38908-deu-Einsatz_von_Machine_Learning_zur_Erstellung_von_XPlanGML_hd.mp4?1710951444</guid> <dc:identifier>bc04dcd3-e5f8-51bd-ab9e-083047255372</dc:identifier> <dc:date>2024-03-20T15:25:00+01:00</dc:date> <itunes:author>Julian Zilz</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>fossgis2024, 38908, 2024, Praxisberichte</itunes:keywords> <itunes:summary>Der Vortrag präsentiert einen methodischen Ansatz zur automatisierten Erstellung von XPlanGML im Raster-Umring-Szenario mithilfe von Machine Learning.

Basierend auf OpenLayers und unter Verwendung von Vue werden verschiedenste wiederverwendbare Funktionalitäten publiziert, welche gemeinsam als Kartenklient für zahlreiche Anwendungsgebiete im Einsatz sind. So verwenden Bürger bereits heute POLAR, u. a. im Meldemichel Hamburg, im Denkmalinformationssystem SH, und in einer Vielzahl von Antragssystemen deutscher Behörden. Die Paketbibliothek [POLAR](https://github.com/Dataport/polar) ist darauf ausgelegt, dass aus einem Core- und diversen Plugin-Paketen ein Kartenklient zusammengesteckt wird, der bereits einen Großteil der Anforderungen abdeckt. Für generische Anwendungsfälle kann auch ein generischer Klient genutzt werden, der dann nur noch über Konfiguration auf die Situation angepasst wird. Der Fokus liegt allerdings auf Erweiterbarkeit: Da Klienten oft noch einsatzspezifische "kleine Details" benötigen, können sowohl eigene Plugins ergänzt, als auch spezifischer Klientencode geschrieben werden, um diese Lücken zu füllen. So sind wiederkehrende Anforderungen wie Zeichenfunktion, Geolokalisierung, Addresssuche, Pin-Funktion, uvw. bereits erledigt – sowie weitere einsatzspezifische Details schnell ergänzt. Der Klient kann als Ganzseitenapplikation verwendet werden, ist aber als Komponente konzipiert. Hierzu wird er stets in einem ShadowDOM gerendert, um Style-Konflikte mit einer umliegenden Applikation zu vermeiden. Zugleich wird eine Datenschnittstelle angeboten, um Daten leicht ein- und ausgeben zu können. Die Kartenapplikation funktioniert dann "wie ein Input-Element" für ein umgreifendes Formular. Dazu gehören Verwendbarkeit auf mobilen Geräten wie auch ein möglichst hoher Grad an Barrierearmut zu den Grundsätzen. Im Falle des [Denkmalinformationssystems SH](https://efi2.schleswig-holstein.de/dish/dish_client/index.html) kann der Kartenklient benutzt werden, um die in SH dokumentierten Denkmäler einzusehen und weitere Informationen zu ihnen zu erhalten. Im [Hamburger Meldemichel](https://static.hamburg.de/kartenclient/prod/) wiederum können Bürger Schäden an öffentlicher Infrastruktur sowohl einsehen als auch melden.

Contents of RDF data are deployed interoperably accessible for many research communities. Our talk shows the tool's motivation, conversion process with test datasets, discusses limitations, standardization issues and future developments of this approach in general. A pertaining problem for linked open (geo-)datasets hosted on the web is the difficulty of their accessibility for people who do not have a previous knowledge about the datastructures and the software to process [RDF](https://www.w3.org/TR/rdf11-concepts/). Often, researchers are only interested in the question if a dataset is suitable for their needs, which warrants an easy discovery of linked open data content with common tools used by the research community they are familiar with. For example: A GIS researcher expects data to be served using e.g. [OGC API Features APIs](http://features.developer.ogc.org/) in formats such as [GeoJSON](https://datatracker.ietf.org/doc/rfc7946/) or [GML](https://www.ogc.org/standard/gml/), to be processed in tools such as [QGIS](https://www.qgis.org) to allow for an easy accessibility. The GIS researcher is not necessarily proficient in the [SPARQL query language](https://www.w3.org/TR/sparql11-query/) and in RDF-to- Geodata-conversion. This is currently not the case for RDF data dumps, e.g. hosted on [Zenodo](https://zenodo.org) or [Github](https://github.com), since special kinds of data need to be manually extracted and converted to be of use to other communities first. To mitigate this gap in data provision, we present the newly-developed SPARQL Unicorn ontology documentation feature, available as [QGIS plugin](10.5281/zenodo.3786814), a [standalone script](https://github.com/sparqlunicorn/sparqlunicornGoesGIS-ontdoc) and as a [Github Action](https://github.com/sparqlunicorn/sparqlunicornGoesGIS-ontdoc), which allows to create readily-hostable data dumps from RDF data, which can be served using static webspaces such as Github Pages. RDF resources are represented by one HTML and RDF resource each, which are identified by their URI and for dereferencability, ideally hosted at this particular place on the web. In addition to an HTML navigation and search function and a variety of graph analysis formats (e.g. [GraphML](http://graphml.graphdrawing.org), [GEXF](https://gexf.net)), the script is able to generate static API versions e.g. OGC API Features for geospatial data or the IIIF Presentation API for accessing media data. This allows to access geodata encoded in RDF as pre-generated FeatureCollections in e.g. QGIS therefore making geospatial data in RDF directly accessible to the GIS community. In our paper we describe the publication process of several semantically enriched and publicly available geospatial datasets in RDF and how they can be reused in QGIS as FeatureCollections and as RDF using the SPARQLing Unicorn QGIS plugin. The [SPP Dataset](https://github.com/archaeolink/SPP1630Harbours-RDF), the [AncientPorts Dataset](https://github.com/archaeolink/AncientPorts_RDF) and the [CIGS Datatset](https://github.com/archaeolink/CIGS_RDF) highlight the representation of (spatio-)temporal research data referenced by scientific literature and serve as examples for the OGC API features integration. In addition, we highlight the publication of [IIIF](https://iiif.io/api/presentation/3.0/) content (e.g. as complementary data to geodata) using the example of [ARS-LOD](https://github.com/RGZM/ars-lod/). Finally, we discuss further extensions of the plugin for other statically generated content, limitations of the current approach and highlight the importance of this way of publishing for the general public and in a research software engineering setup. about this event: https://pretalx.com/fossgis2024/talk/GKTTQH/ </description> <enclosure url="https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-39049-deu-The_SPARQL_Unicorn_Ontology_documentation_Exposing_RDF_geodata_using_static_GeoAPIs_hd.mp4" length="177209344" type="video/mp4"/> <pubDate>Wed, 20 Mar 2024 17:40:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-39049-deu-The_SPARQL_Unicorn_Ontology_documentation_Exposing_RDF_geodata_using_static_GeoAPIs_hd.mp4?1710959017</guid> <dc:identifier>d341301c-6358-5866-83e1-d9e7ee18ee32</dc:identifier> <dc:date>2024-03-20T17:40:00+01:00</dc:date> <itunes:author>Florian Thiery, Timo Homburg</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>fossgis2024, 39049, 2024, Daten, Datenbanken und Datenprozessierung</itunes:keywords> <itunes:summary>We introduce the ontology documentation feature of the SPARQLing Unicorn QGIS Plugin, allowing the conversion of RDF data dumps to static HTML deployments with static versions of well-known APIs such as OGC API Features.

Die OpenSource-Anwendung xPlanBox unterstützt die Kommunen als zentrales Managementverfahren für sämtliche Planwerke sowie als Bereitstellungsplattform von XPlanung-Daten. Durch Containerlösungen ist der Betrieb für mehrere Mandanten einfach möglich, ebenso der Zugriff auf die Daten durch die Integration im Masterportal. Die Anwendung xPlanBox der Firma lat/lon steht unter opencode.de als OpenSource-Verfahren allen Interessierten zur Verfügung. Die Anwendung dient auf kommunaler Ebene der Abbildung der Bauleit- und der Landschaftsplanung auf Basis des verbindlichen Standards XPlanung. Das Kommunale Rechenzentrum Niederrhein (KRZN) stellt seit 2022 für über 40 Kommunen am linken Niederrhein die xPlanBox als zentrales Managementverfahren für sämtliche Planwerke der Kommunen sowie als Bereitstellungsplattform von XPlanung-Daten bereit. Auf dieser Basis werden die von den Kommunen bereitgestellten Planwerke nach erfolgreicher Validierung über OGC-Geoservices in die Geodateninfrastruktur des KRZN integriert, sodass die Daten allen Mitarbeiter:innen der Kommunen, aber auch der Zivilgesellschaft (Planungsbüros, Wirtschaft, …) über Geoportale – im KRZN auf Basis des Masterportals - zur Verfügung stehen. Die betroffenen Planarten – aktuell Bebauungs- und Flächennutzungspläne, zukünftig auch Landschaftspläne – werden für alle Kommunen in einer im Verbandsgebiet des KRZN abgestimmten einheitlichen Darstellung über WebMapServices bereitgestellt, zum Beispiel für die Auskunft in einem Geoportal. Auswertungen und Analysen können über WebFeatureServices beispielsweise in QGIS durchgeführt werden. Vorhandene APIs bieten als Schnittstellen weitere Nutzungsmöglichkeiten. Daneben ermöglicht der Einsatz von Containerlösungen einen stabilen und flexiblen Betrieb. Zudem kann so der Aufbau einer Umgebung für mehrere Mandanten einfach realisiert werden. Der Vortrag soll u.a. aufzeigen, • wie die xPlanBox in einer Mehrmandantenumgebung betrieben werden kann, • welche Möglichkeiten die xPlanBox den Kommunen in der täglichen Praxis bietet und • wie sich die Datenintegration in Masterportal, QGIS und in 3D-Portalen gestaltet. about this event: https://pretalx.com/fossgis2024/talk/SVQLL3/ </description> <enclosure url="https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-38903-deu-xPlanBox_kommunale_Datendrehscheibe_fuer_die_Bauleit-_und_Landschaftsplanung_hd.mp4" length="183500800" type="video/mp4"/> <pubDate>Wed, 20 Mar 2024 14:15:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-38903-deu-xPlanBox_kommunale_Datendrehscheibe_fuer_die_Bauleit-_und_Landschaftsplanung_hd.mp4?1710946196</guid> <dc:identifier>15068734-a33b-55e8-910c-cf8905056eaa</dc:identifier> <dc:date>2024-03-20T14:15:00+01:00</dc:date> <itunes:author>Stefan Peuser</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>fossgis2024, 38903, 2024, Praxisberichte</itunes:keywords> <itunes:summary>XPlanung ist der verbindliche Standard für die Bauleit- und Landschaftsplanung auf kommunaler Ebene.

Der Vortrag stellt die Möglichkeiten der (OGC-)Dienst-Orchestrierung am Beispiel von Kubernetes vor und beleuchtet die Vor- und Nachteile dieser Entwicklungen. Der klassische GeoServer als monolithische Serverlösung stößt im Umfeld moderner Microservice-Architekturen schnell an technische Grenzen. Diesen Problemen tritt das "GeoServer Cloud" Projekt (https://github.com/geoserver/geoserver-cloud) entgegen, indem bestehende GeoServer-Implementierungen durch Erweiterung und Anpassung in individuell einsetzbare Einzelkomponenten transformiert werden. Diese können dann im Rahmen einer Microservice-Architektur in Container-basierten Verwaltungsumgebungen wie beispielsweise Kubernetes eingesetzt und beliebig skaliert werden. Der Vortrag beleuchtet die technischen Konzepte (dynamic service discovery, externalized configuration, distributed events, API gateway) und diskutiert Vor- und Nachteile dieser Entwicklungen. Am Beispiel eines lokalen KIND-Setups (Kubernetes in Docker) werden die Möglichkeiten in aller Kürze veranschaulicht. about this event: https://pretalx.com/fossgis2024/talk/FPU77T/ </description> <enclosure url="https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-38423-deu-GeoServer_Cloud_mit_Kubernetes_hd.mp4" length="190840832" type="video/mp4"/> <pubDate>Wed, 20 Mar 2024 15:25:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-38423-deu-GeoServer_Cloud_mit_Kubernetes_hd.mp4?1710954136</guid> <dc:identifier>b4a26563-432e-5587-86f1-21e1326f20c9</dc:identifier> <dc:date>2024-03-20T15:25:00+01:00</dc:date> <itunes:author>Nils Bühner</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>fossgis2024, 38423, 2024, Neuigkeiten aus den Open-Source-Projekten</itunes:keywords> <itunes:summary>"GeoServer Cloud" ist ein Projekt, welches das Ziel verfolgt die vom klassischen GeoServer implementierten OGC-Standards und weitere Schnittstellen als individuell skalierbare Microservices "cloud native" in einer Container-basierten Umgebung bereitzustellen.

Im Lightning Talk sollen die wesentlichen Funktionen des 3DProjektplaners sowie mögliche Anwendungsfälle des Tools aufgezeigt werden. Der 3DProjektplaner ist eine digitale Webanwendung, die es planenden Dienststellen in der Verwaltung ermöglicht, Bauvorhaben im Stadtkontext geodatenbasiert zu analysieren sowie eigene städtebauliche Entwicklungsideen schnell und einfach zu skizzieren. Aktuell stehen Fachämtern zur Prüfung von Bauvorhaben in frühen Planungsphasen oftmals nur gedruckte Pläne und Renderings zur Verfügung und beim Entwickeln neuer städtebaulicher Ideen wird in der Amtsstube zumeist zum gedruckten Luftbild und Zeichenpapier gegriffen. Das Problem: papiergebundene Entwurfsprozesse kosten Zeit und vor allem fehlt oft die Möglichkeit, das Vorhaben in frühen Planungsphasen mit dem Kontext der gebauten Stadt fundiert und datenbasiert in Abgleich zu bringen. Mit dem 3DProjektplaner kann ein Bauvorhaben im 3D-Stadtmodell digital platziert werden, um es bspw. im baulichen Umfeld zu analysieren, mit weiteren Geodaten wie z. B. digitalen Bebauungsplänen zu verschneiden oder Schattenwurfsimulationen durchzuführen. Außerdem können mithilfe leicht zu bedienender Zeichenwerkzeuge Bestandsgebäude ausgeblendet, einfache städtebauliche Skizzen in wenigen Minuten hergestellt und diese für die weitere Verwendung als PDF gespeichert oder ausgedruckt werden. Auf diese Weise schafft der 3DProjektplaner besonders in frühen Planungsphasen mithilfe von Geodaten und innovativen 3D-Technologien neue Perspektiven für die Stadtentwicklung. Der 3DProjektplaner wurde als Werkzeug für planende Dienststellen der Verwaltung entwickelt und unterstützt diese in den vielfältigen Fragestellungen und Abstimmungsprozessen sowohl verwaltungsintern als auch mit Privaten. Da es sich um eine Webanwendung handelt, die im Browser aufgerufen werden kann, wird für die Nutzung keine spezielle Hardware benötigt. Technische Grundlage des 3DProjektplaners ist das Masterportal, das hierfür im Rahmen des Projektes Connected Urban Twins (CUT) auf Grundlage intensiver Anforderungserhebungsprozesse von der Behörde für Stadtentwicklung und Wohnen in Zusammenarbeit mit Dataport im Bereich 3D weiterentwickelt wurde. Zu den neu entwickelten Funktionen gehören: - 3D Importer - 3D Draw - Sichtperspektiven - Ausblenden von Objekten des 3D-Stadtmodells Die Funktionen werden in der Masterportal-Toolbox „3D Modeller“ gebündelt und sind Teil des Masterportal-Cores. Alle Entwicklungen sind OGC-konform und wurden explizit als Open Source Software entwickelt.

In diesem Vortrag werden bewährte Methoden und Werkzeuge beleuchtet, die die Entwicklung von GRASS GIS Addons effizienter und zugänglicher gestalten. Der Fokus liegt auf erprobten Praktiken beim Schreiben von GRASS GIS Addons, die es ermöglichen, hochwertige Erweiterungen zu erstellen und in die GRASS GIS Umgebung zu integrieren. Außerdem wird die Bibliothek ["grass-gis-helpers"](https://github.com/mundialis/grass-gis-helpers) vorgestellt, die die Entwicklung von GRASS GIS Addons erleichtert und wertvolle Werkzeuge und Hilfsmittel bereitstellt. Ein weiterer Aspekt des Vortrags wird die Nutzung [wiederverwendbarer Workflows](https://github.com/mundialis/github-workflows) sein. Hier wird erklärt, wie man Workflows zum Linten und Testen in die GRASS GIS Addon Entwicklung integrieren kann, um die Qualität der Erweiterungen sicherzustellen.

Doch welchen Weg durch die GIS-Welt geht ein Schlagloch bis es auf einer Karte in der zuständigen Verwaltung landet? Und welche Rolle spielen hier Freie und Open-Source Software? Ein Schlagloch ist ein geographisches Objekt, es hat Koordinaten und passt damit wunderbar zu einem GIS. Doch wie kommt es dahin? Um die Koordinaten eines einzelnen Schlaglochs aufzunehmen, kann man selber rausgehen und sich mit einem GPS dazu stellen. Wenn man aber alle Schlaglöcher einer Gemeinde mit vielleicht mehreren hundert Kilometer an Wegenetz hat, dann ist dies nicht mehr wirklich praktikabel. Auch gibt es genug Autofahrende die wenig entspannt reagieren, wenn man auf der Straße rumläuft, selbst wenn man eine Warnweste trägt und eine GPS-Antenne in der Hand hält. Deswegen gibt es die Möglichkeit, ein mit Kameras und Scanner ausgestattetes Fahrzeug in den fließenden Verkehr zu schicken. Doch wo bleibt das GIS? Damit das Fahrzeug weiß, auf welchen Straßen und Wegen es unterwegs sein soll, werden im Vorfeld Daten gesammelt. Einige Bundesländer stellen Daten wie DOP und ALKIS als OpenData zur Verfügung, daneben gibt es in den für die Unterhaltung der Straßen zuständigen Straßenbauverwaltungen bereits existierende (GIS-)Daten und natürlich die reichhaltigen Datenbestände aus OSM. Damit haben wir Daten aus verschiedensten Datenquellen, die in einem QGIS-Projekt zusammengefasst werden können und in dem dann die Wege markiert werden, die erfasst werden sollen. Dieses QGIS geht dann mit raus auf den Rechner im Fahrzeug. Der Fahrer (wir haben leider nur Männer im Außendienst) weiß damit wo er lang muss und durch die Verbindung mit dem GPS weiß das QGIS wo gefahren wird, markiert die Straßen gleich ab womit der Fahrer gleich weiß wo er schon war. Und wie kommt jetzt das Schlagloch ins GIS rein? Durch die Kalibrierten Kameras auf den Fahrzeugen lässt sich in den Bildern Messen, ein Klick im Bild gibt eine Koordinate die im QGIS erscheint und dort mit Attribut versehen als Objekt in einer Tabelle in einer PostGIS-Datenbank landet. Einmal ein GIS-Objekt in der Datenbank, steht der kartographischen Aufbereitung nichts mehr im Weg. Was hier am Beispiel des Weges eines Schlaglochs von der Straße ins GIS beschrieben wurde, lässt sich nun natürlich auch auf anderes anwenden, z.B. auf andere Merkmale des Straßenzustands wie Risse, Flickstellen, etc. aber auch auf sämtliche anderen Objekte die von den Kameras erfasst werden. Wenn diese Merkmale des Straßenzustands erst einmal als Objekte im GIS sind, dann wird es erst richtig spannend, jedenfalls aus der Sicht eines GIS-Menschen mit Freude am Ausprobieren und Anwenden von Verarbeitungswerkzeugen im QGIS und an PostGIS-Funktionen: - In welcher Straße sind die meisten Risse aber die wenigsten Flickstellen? - Wieviel Prozent einer Straße haben Schlaglöchern oder anderen Schäden? Also welcher Anteil der Straßenfläche ist geschädigt? - An welcher Position entlang der Straße befindet sich ein Schlagloch? - Wenn es zusätzliche Angaben zu Baukosten und Alter einer Straße gibt, dann können zusammen mit den Infos zu den Schäden auch Berechnungen zum Wert einer Straße generiert werden. Vereinfacht: Je älter und je mehr Schäden umso geringer der Wert. Die komplette Bearbeitung der GIS-Daten, von der Planung am Anfang und der Befahrung im Fahrzeug, über die vielfältigen Berechnungen, Verschneidungen und Analysen bis hin zur kartografischen Ausgabe erfolgt komplett in QGIS und in einer PostgreSQL/PostGIS Datenbank. In dem vielfältigen Zusammenspiel in der GIS-Welt zwischen Punkt-, Linien und Flächenobjekten, zeigen wir einige Beispiele aus dem Bereich der Straßenzustandserfassung auf. about this event: https://pretalx.com/fossgis2024/talk/3Z9VLD/ </description> <enclosure url="https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-38990-deu-Der_Weg_eines_Schlaglochs_von_der_Strasse_auf_die_Karte_hd.mp4" length="540016640" type="video/mp4"/> <pubDate>Wed, 20 Mar 2024 12:20:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-38990-deu-Der_Weg_eines_Schlaglochs_von_der_Strasse_auf_die_Karte_hd.mp4?1710939973</guid> <dc:identifier>de3918e6-6582-53f0-9b30-ef28824cf126</dc:identifier> <dc:date>2024-03-20T12:20:00+01:00</dc:date> <itunes:author>Asmus Harder, Melanie Fleischer</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>fossgis2024, 38990, 2024, Praxisberichte</itunes:keywords> <itunes:summary>Jeder und jede von uns hat sich sicher schon einmal darüber geärgert: nichts Böses ahnend bleibt der Fuß oder das Rad in einem Schlagloch hängen, dass so tief ist, dass es fast auf die andere Seite der Erde reicht.

Fokus dieser Präsentation ist die technische Umsetzung dieser Explorationswerkzeuge. Das Weltwärmestrom Datenbank Projekt setzt sich als Ziel eine neue Forschungsdateninfrastruktur (Web Portal) für terrestrische Wärmestromdaten zu entwickeln. Über die letzten Jahrzehnte ist eine umfangreiche, globale Datensammlung zum Thema Wärmestrom entstanden, welche über eine zentrale Anlaufstelle im Internet durch Einhaltung der FAIR und OPEN Datenpolitik zur Verfügung gestellt werden soll. Neben den Daten selbst, bietet die Anwendung eine integrierte Literaturdatenbank, einen internen Bereich für registrierte Nutzende, eine API und fachbezogene Explorationswerkzeuge, welche hier detaillierter beschrieben werden. Das Paper beschäftigt sich mit den Funktionalitäten des Web Portals, welche durch eine Anforderungsanalyse erfasst wurden, und beschreibt die für die Umsetzung verwendeten Komponenten. Die Explorationswerkzeuge sind hierbei ein separates Modul, welche in VueJS implementiert wurden und über npm in die Projekthomepage eingebunden werden. Als Input benötigt die Anwendung Punktdaten und eine Schema Datei für die Datenbeschreibung. Zentral für die Datenexploration ist ein auf MapLibre basierender Kartenviewer, der die georeferenzierten Punktdaten auf einer Weltkarte darstellt.

In dieser Präsentation werden wir sowohl den aktuellen Stand des Projekts GeoNetwork-UI, das innovative Design des neuen Metadaten-Editors, als auch die bevorstehenden Entwicklungen vorstellen. Der Vortrag stellt die neuesten Entwicklungen im Open Source Projekt GeoNetwork-UI vor. Zentrales Ziel von GeoNetwork-UI ist es, eine Alternative zum veralteten Frontend von GeoNetwork zu liefern. Neben der Modernisierung der Benutzeroberfläche von GeoNetwork, entstand GeoNetwork-UI aus der Notwendigkeit, neue Anwendungsfälle beim Arbeiten mit Metadaten anzugehen und eine erheblich verbesserte Benutzererfahrung zu bieten. Beispielsweise wird durch das Geonetwork-UI eine einfachere Datenaufnahme mit automatischer Befüllung der Metadaten geboten. Außerdem bietet es Formulare passend zu jeder Organisation und eine automatische Speicherung der Daten im Entwurf-Modus. Einer der Hauptkritikpunkte der ursprünglichen GeoNetwork-Anwendung war die komplizierte Eingabe über den Metadaten-Editor, der zwar viele Standards unterstützt, als Konsequenz aber sehr umfangreiche und komplexe Eingabemasken für den Benutzer bereitstellt. Ein bekanntes Beispiel sind die XML-Schemas der ISO19139, die aufgrund ihrer Komplexität viele Nutzer:innen überfordern. Dieses Problem soll mit Hilfe des neu erstellten Metadaten-Editors angegangen und verbessert werden. Die Zusammenarbeit zwischen den Mitgliedern innerhalb einer Organisation wird ebenfalls erleichtert, z.B. können Nutzer:innen gegenseitig um Feedback und Reviews bitten. In diesem Vortrag werden wir daher einige typische Use Cases vorstellen, die dies veranschaulichen. Außerdem werden cutting-edge Technologien wie z.B. “Web-Components” und fortschrittliches Theming mit CSS-Variablen vorgestellt. Es wird auf die einfache Konfiguration und Deployment eingegangen. Zudem wird auf die Kompatibilität von Geonetwork-UI mit Geonetwork 4.2 hingewiesen.

Zudem wird auf die Kompatibilität von Geonetwork-UI mit Geonetwork 4.2 hingewiesen. GeoNetwork-UI ist ein vielversprechendes Projekt mit einer wachsenden Gemeinschaft, und wir freuen uns darauf, die Anwendung und deren potentielle Einsatzbereiche im Detail vorzustellen. about this event: https://pretalx.com/fossgis2024/talk/7XRXPS/ </itunes:summary> <itunes:duration>00:21:12</itunes:duration> </item> <item> <title>Open Source and Web-Based GeoAI tool for Transparent Forest Fire Prediction (fossgis2024)</title> <link>https://media.ccc.de/v/fossgis2024-38924-open-source-and-web-based-geoai-tool-for-transparent-forest-fire-prediction</link> <description>Utilizing open geospatial data and AI, we are trying to predict forest fire susceptibility in Brandenburg. This case study showcases full-stack web-GIS, emphasizing user interaction and transparent AI through open-source tools like GEE, GDAL, Python, Maplibre, and TiTiler. The advancement of AI algorithms has led to their widespread adoption in Geographic Information Science (GIS) applications, encompassing areas such as natural and humanitarian crises, location-based services, and urban planning, collectively referred to as GeoAI. Given the inherent opacity of AI systems, their integration in decision-making processes necessitates a degree of transparency and explainability. We address the imperative of eXplainable AI (XAI) within web-based GIS applications. To this end, we present a case study focused on forest fire susceptibility in the state of Brandenburg, Germany. Leveraging open remote-sensing data, alongside established open-source geospatial tools like Google Earth Engine (GEE) and GDAL, we undertook the aggregation and preprocessing of satellite imagery. This process was complemented by Python for model training, TiTiler for raster tile service, and a frontend application developed with Vue.js and Maplibre GL JS for user interaction and map rendering. For the vital aspect of explainability, we employed the SHAP (SHapley Additive exPlanations) Python library to quantify the influence and contribution of each predictor at user-specified locations to provide an explanation of why the AI model made a certain prediction at a specific geographical location. In this pursuit, we considered three primary categories of factors: topographic attributes (Elevation, Aspect, and Slope), meteorological variables (Global Radiation, Land Surface Temperature, Precipitation, and Drought Index), and vegetation indices (NDVI, NDMI, GNDMI, and Land Cover). Historical wildfire incident data spanning from 2013 to 2023 served as the inventory dataset derived from MODIS. NDVI, NDMI, and GNDMI metrics were derived from Sentinel-2 imagery utilizing GEE, while GDAL was employed for necessary calculations based on relevant bands. Topographic and meteorological data sets were sourced from OpenDEM and Deutscher Wetterdienst (DWD), respectively, and underwent preprocessing via GDAL and associated utility tools. This encompassed image format conversion, re-projection, mosaicking, and image classification using gdal_translate, gdalwrap, and gdal_calc.py. The combination of these processed inputs, using Python's Geopandas, resulted in distinct training and testing datasets. The Random Forest algorithm was selected to train the prediction model. Subsequently, the resulting fire susceptibility map underwent processing in TiTiler to create map tiles and a Cloud Optimized GeoTIFF (COG) file. The generated map was seamlessly integrated into the frontend application, enhancing user interaction. For enhanced interpretability and interaction with the AI model, an API was developed. It accepts pixel coordinates of selected fire susceptibility values from the front-end leveraging the SHAP Python package to quantify the significance and contribution of each predictor. These insights are then presented in the frontend interface, ensuring a comprehensive and accessible user experience. about this event: https://pretalx.com/fossgis2024/talk/TCVX3C/ </description> <enclosure url="https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-38924-eng-Open_Source_and_Web-Based_GeoAI_tool_for_Transparent_Forest_Fire_Prediction_hd.mp4" length="375390208" type="video/mp4"/> <pubDate>Wed, 20 Mar 2024 17:40:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/fossgis/2024/h264-hd/fossgis2024-38924-eng-Open_Source_and_Web-Based_GeoAI_tool_for_Transparent_Forest_Fire_Prediction_hd.mp4?1710958799</guid> <dc:identifier>5c572a75-5624-598c-85ed-d1a0a5cc29e7</dc:identifier> <dc:date>2024-03-20T17:40:00+01:00</dc:date> <itunes:author>Qasem Safariallahkheili, Sebastian Meier</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>fossgis2024, 38924, 2024, Raum-zeitliche Analysen und Modelle</itunes:keywords> <itunes:summary>Utilizing open geospatial data and AI, we are trying to predict forest fire susceptibility in Brandenburg.

Starkregen) führt. Das Bundesamt für Kartografie und Geodäsie hat das Ziel, eine bundesweit einheitliche Starkregengefahrenhinweiskarte zu erstellen. Die Arbeitsgemeinschaft (Fischer Teamplan und Weber–Ingenieure) erstellt derzeit mit OpenSource-Software (HiPIMS und QGIS) und überwiegend mit OpenData diese Karten für Niedersachsen/Schleswig-Holstein/Bremen und Hamburg. Bereits 2019 haben wir im Auftrag des Bundesamts für Kartographie und Geodäsie das Pilotprojekt Starkregengefahrenhinweiskarte NRW bearbeitet. Das Ziel ist eine bundesweit einheitliche Erstellung einer Starkregengefahrenhinweiskarte zur Informationsvorsorge und als Grundlage für weiterführende Schutzmaßnahmen und Risikoanalysen. Seit Anfang 2023 werden für 10 Bundesländer weitere Karten erstellt. Von uns werden derzeit die Bundesländer Niedersachsen/Schleswig-Holstein/Bremen und Hamburg auf ihre Starkregengefahr hin untersucht. Dazu wurden als Eingangsdaten überwiegend OpenData (beispielsweise von der Bundesanstalt für Gewässerkunde, dem Deutschen Wetterdienst und länderspezifische Daten) verwendet. Hinzu kamen jedoch auch nutzungseingeschränkte Daten (Deutsche Bahn, Bundesanstalt für Straßenwesen, länderspezifische Daten, Unterhaltungsverbände). Die Berechnung (2D-Oberflächenabflusssimulation) haben wir mit der OpenSource Software HiPIMS (high-performance integrated hydraulic and hydrological modelling software (https://github.com/lukeshope/hipims-ocl)) durchgeführt. Wir haben ein Modell mit einer Auflösung von 1x1m für eine Gesamtfläche von rund 69.000 km² aufgestellt und die rund 175.000 wasserwirtschaftlich relevanten Sonderbauwerke (Brücken/Durchlässe/Schöpfwerke) hydraulisch abgebildet. Die Datenaufbereitung erfolgte mit QGIS und Nutzung von QGIS Model Builder sowie automatisierten Abfragen und Routinen. In unserem Vortrag gehen wir auf die technische Umsetzung mithilfe diverser OpenSource-Werkzeuge ein: - Die manuelle Datenverarbeitung von Massendaten im GIS - Die geskriptete Anwendung von GIS Tools im Cluster - Die Einbindung von KI in Prozesse der Geodatenverarbeitung Derzeit liegt eine Vorsimulation für das Gesamtgebiet vor und es erfolgt eine digitale Überprüfung der Ergebnisse bezüglich der Wassertiefe und Ausdehnung der Überflutungsflächen. Im Frühjahr 2024 liegen die plausibilisierten Starkregengefahrenhinweiskarten vor.

Der DD-IX Dresden Internet Exchange e. V. wurde Ende 2023 mit dem Ziel gegründet, einen Community IX für Dresden und die Region Sachsen zu betreiben. In diesem Vortrag geben wir einen kurzen Abriss der Internet-Architektur und zeigen die Relevanz und die technischen Herausforderungen beim Betrieb von IXen auf. Danach stellen wir den DD-IX im Detail vor. Dabei gehen wir auf die Gründung, die Community und die Unterstützung durch erfahrene Dritte ein. Schließlich stellen wir unser technisches Setup für den IX-Betrieb und die Vereinstechnik vor. about this event: https://chemnitzer.linux-tage.de/2024/de/programm/beitrag/245 </description> <enclosure url="https://cdn.media.ccc.de/events/clt/2024/h264-hd/clt24-73-deu-DD-IX_Keep_Local_Traffic_Local_hd.mp4" length="252706816" type="video/mp4"/> <pubDate>Sun, 17 Mar 2024 15:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/clt/2024/h264-hd/clt24-73-deu-DD-IX_Keep_Local_Traffic_Local_hd.mp4?1710782329</guid> <dc:identifier>1610d371-80fd-5950-932f-240c23a971ee</dc:identifier> <dc:date>2024-03-17T15:00:00+01:00</dc:date> <itunes:author>Thomas Liske</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>clt24, 73, 2024, Vortrag</itunes:keywords> <itunes:summary>Für das Internet sind Internet eXchanges (IX) wichtige Knotenpunkte, um Netzwerkverkehr zwischen Providern, Inhaltsanbietern und Konsumenten robust und mit geringen Verzögerungen auszutauschen.

Doch nicht jeder hat Zugang zu diesen Technologien. Der rasche technische Fortschritt verkürzt die Nutzungsdauer von Computern, was zu einem Überschuss an ausgemusterten, aber noch funktionsfähigen Geräten führt. Wir, die Mitglieder des Vereins Computertruhe e. V., greifen hier ein. In unserer Freizeit bringen wir gespendete Computer und andere Hardware wieder in Stand, löschen alle persönlichen Daten und geben die Geräte kostenlos an Bedürftige und gemeinnützige Organisationen weiter. Unser Handeln schafft eine Verbindung zwischen dem Überschuss an Computern und der Möglichkeit digitaler Teilhabe für Menschen, die sich sonst keine eigene Technik leisten könnten. Dabei schonen wir die Umwelt durch die Wiederverwendung funktionsfähiger Geräte und den Einsatz von Open-Source-Lösungen. In unserem Vortrag auf den Linux-Tagen erläutern wir, wie wir durch Open-Source-Software wie Linux und LibreOffice sowie einer digitalen und papierlosen Organisation effizient und ortsunabhängig arbeiten. Wir teilen unsere dreijährigen Erfahrungen aus den Standorten Chemnitz und Zwickau, diskutieren, wie man sich uns anschließen oder eigene Standorte gründen kann.

Dies funktioniert recht gut mit einem Gerät, skaliert aber nicht besonders gut. Insbesondere im Cloud-Umfeld oder bei DevSecOps-Containern funktionieren Passwörter nur bedingt.

So kann man z.B. in der Network Based Disk Encryption Volumes mittels LUKS verschlüsseln und den Schlüssel zur Entschlüsselung beim booten von einem Server abholen.

Open Source Projekte bringen Teams aus unterschiedlichsten Ländern zusammen, die über die Grenzen von Unternehmen hinweg gemeinsam Software entwickeln und so die Basis für Innovationen für alle schaffen.

Hierzu werden einerseits Standards für den Cloud-Stack definiert. So können bestehende Lösungen den Standards angepasst werden und kompatibel sein. Andererseits wird im Rahmen des Projekts eine Referenzimplementierung entwickelt, die aus existierenden Open-Source-Softwaremodulen besteht und die SCS-Standards in der Praxis umsetzt. Durch die Verbindungen zu Linux Foundation, CNCF und der OIF wird darüber hinaus ein aktiver Beitrag zu den jeweiligen Upstreams geleistet. Der starke Fokus auf Standards und freie Lizenzen soll aktiv einem Vendor-Lock-In entgegen wirken. Ein Wechsel des Anbieters kann ohne aufwendige Migrationsinvestitionen durchgeführt werden. Für Anbieter bedeutet die Standardisierung auch, dass für spezialisierte Services in ihrer Cloud auf einen verlässlichen Unterbau zurückgegriffen werden kann. Im aktuellen Stand ist die seit 2020 in Entwicklung befindliche Plattform bereits am Markt, Instanzen des SCS werden von großen deutschen CSPs an Kunden offeriert. Andere Anbieter schließen ihre Cloud-Angebote über die SCS-Standards an den Verbund an. Dadurch wächst sozusagen ein föderierter, offener Hyperscaler. Finanziert wird das Vorhaben als Projekt des Open Source Business Alliance - Bundesverband für digitale Souveränität e.V. von Fördergeldern des BMWK. In Zukunft soll das Projekt sich selbst tragen, die Ergebnisse als marktreifes Produkt in der Breite verwendet und weiterentwickelt werden. In diesem Vortrag stellen wir euch die Hintergründe des SCS vor, zeigen auf, wo das Projekt gerade steht und wie die Zukunft aussehen könnte. Darüber hinaus geben wir euch Einblicke in die Erfahrungen mit der Community und wo für Interessierte die besten Einstiegspunkte sind. about this event: https://chemnitzer.linux-tage.de/2024/de/programm/beitrag/304 </description> <enclosure url="https://cdn.media.ccc.de/events/clt/2024/h264-hd/clt24-157-deu-Sovereign_Cloud_Stack_-_Hintergruende_Zukunft_hd.mp4" length="162529280" type="video/mp4"/> <pubDate>Sun, 17 Mar 2024 12:30:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/clt/2024/h264-hd/clt24-157-deu-Sovereign_Cloud_Stack_-_Hintergruende_Zukunft_hd.mp4?1710683066</guid> <dc:identifier>7cb3bbfc-eeb4-506e-ac82-bfb032ea17c5</dc:identifier> <dc:date>2024-03-17T12:30:00+01:00</dc:date> <itunes:author>Dominik Pataky</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>clt24, 157, 2024, Vortrag</itunes:keywords> <itunes:summary>Das Open-Source-Projekt „Sovereign Cloud Stack“ hat sich zum Ziel gesetzt, ein offenes Netzwerk für die gemeinsame Entwicklung von standardisierten und interoperablen Cloud-Technologien zu werden.

Dabei geben wir Einblicke in unsere Arbeit als Admins und zeigen was für uns in den genannten Bereichen gut funktioniert. about this event: https://chemnitzer.linux-tage.de/2024/de/programm/beitrag/154 </itunes:summary> <itunes:duration>00:57:41</itunes:duration> </item> <item> <title>Xorg ist tot, nutzen Sie Wayland (clt24)</title> <link>https://media.ccc.de/v/clt24-284-xorg-ist-tot-nutzen-sie-wayland</link> <description>Die Entwicklung des Xorg-Servers ist kaum noch aktiv.

Diese Produkte sind mehr als nur Werkzeuge; sie sind die Superhelden Ihrer IT-Infrastruktur. Lasst uns gemeinsam eintauchen in: "Of Heroes and Hypervisors: Proxmox VE & Proxmox Backup Server unleashed" Wir beginnen mit einer aufregenden Tour durch die beeindruckenden Features von Proxmox VE und Proxmox Backup Server. Dann erkunden wir verschiedene Ausbauvarianten, beginnend mit einem Single-Node-Setup und arbeiten uns zu Clustering-Optionen mit ihren vielfältigen Vorteilen vor. Ein besonderer Schwerpunkt liegt auf der Hochverfügbarkeit, wir zeigen euch, wie diese Technologien eure IT-Infrastruktur stärken können. Wir präsentieren euch Ceph und enthüllen seine Superkräfte, begleitet von einer Live-Demo eines 3 Node Proxmox VE & Ceph Clusters. Für diejenigen, die noch tiefer in die Welt von Ceph eintauchen möchten, bieten wir Informationen zu Deployment-Varianten und Benchmarks. Schließlich erfahrt ihr mehr über unseren Service und Support und wie Proxmox VE bei der Thomas-Krenn.AG für unsere Kunden zum Einsatz kommt.

Dass die Nutzung eigentlich einfach ist, wenn man ein paar Informationen hat, wird in diesem Vortrag gezeigt.

Und wir legen nochmal nach und laden ein, sich für die 16. Runde zu bewerben: Es winken 47.500 € über sechs Monate Förderung durch das Bundesministerium für Bildung und Forschung. Aber nicht nur finanziell werden die Entwickler*innen und Teams gefördert, wir bieten auch Zugang zu Coachings, Netzwerken und Weiterbildungen. Das alles gibt es zum unschlagbaren Preis einer möglichst unbürokratischen Bewerbung. Wir stellen in diesem Vortrag kurz vor, was den Prototype Fund ausmacht ist, bringen ein paar Beispielprojekte mit, geben ein paar Tipps zur Bewerbung und sprechen darüber, wie nachhaltige Projektentwicklung klappen kann. Anschließend wird es Zeit für eure Fragen geben. about this event: https://chemnitzer.linux-tage.de/2024/de/programm/beitrag/183 </description> <enclosure url="https://cdn.media.ccc.de/events/clt/2024/h264-hd/clt24-143-deu-Cash_Cash_Cash_-_Prototype_Fund_Runde_16_hd.mp4" length="196083712" type="video/mp4"/> <pubDate>Sun, 17 Mar 2024 13:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/clt/2024/h264-hd/clt24-143-deu-Cash_Cash_Cash_-_Prototype_Fund_Runde_16_hd.mp4?1710690552</guid> <dc:identifier>7b23a9f2-b050-5a27-a32b-eade566f66c2</dc:identifier> <dc:date>2024-03-17T13:00:00+01:00</dc:date> <itunes:author>Paul Robben</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>clt24, 143, 2024, Vortrag</itunes:keywords> <itunes:summary>Der Prototype Fund fördert seit acht Jahren Open Source Software.

(clt24)</title> <link>https://media.ccc.de/v/clt24-266-ki-hype-oder-was-sind-eigentlich-transformer</link> <description>Von Begriffen wie »Chatbots«, »GPT« und »KI«/»KI-Modellen« spricht heute irgendwie fast jeder. Dabei existiert für viele von uns, wenn wir ehrlich sind, jenseits ihrer offensichtlichen Fähigkeiten sicher nur eine äußerst vage Vorstellung, worum es dabei aus technischer Sicht eigentlich genau geht. »Transformer« sind eine Methode des maschinellen Lernens, die nahezu all diesen Technologien zu Grunde liegt.

Es ist für seinen breiten Funktionsumfang und seine Performance bekannt, insbesondere für die Ausführung von Windows-VMs. Allerdings führt VirtualBox’ Abhängigkeit von einem Out-of-Tree-Kernelmodul (vboxdrv) häufig zu Kompatibilitätsproblemen mit den neuesten Linux-Kerneln und erweiterten Sicherheitsmaßnahmen wie grsecurity/PAX und schließt die gleichzeitige Nutzung von KVM aus. In diesem Vortrag stellen wir ein KVM-Backend für VirtualBox vor, das diese Probleme behebt. Durch die Integration von VirtualBox und KVM können Benutzer KVM und VirtualBox gleichzeitig nutzen, ohne auf die umfangreichen Funktionen von VirtualBox verzichten zu müssen. Das dafür notwendige VirtualBox Patchset ist unter einer Open-Source-Lizenz verfügbar. Wir werden die Implementierung dieses KVM-Backends und seine Vorteile besprechen und Anleitungen zur Verwendung unseres Patchsets geben.

Es ist für seinen breiten Funktionsumfang und seine Performance bekannt, insbesondere für die Ausführung von Windows-VMs. Allerdings führt VirtualBox’ Abhängigkeit von einem Out-of-Tree-Kernelmodul (vboxdrv) häufig zu Kompatibilitätsproblemen mit den neuesten Linux-Kerneln und erweiterten Sicherheitsmaßnahmen wie grsecurity/PAX und schließt die gleichzeitige Nutzung von KVM aus. In diesem Vortrag stellen wir ein KVM-Backend für VirtualBox vor, das diese Probleme behebt. Durch die Integration von VirtualBox und KVM können Benutzer KVM und VirtualBox gleichzeitig nutzen, ohne auf die umfangreichen Funktionen von VirtualBox verzichten zu müssen. Das dafür notwendige VirtualBox Patchset ist unter einer Open-Source-Lizenz verfügbar. Wir werden die Implementierung dieses KVM-Backends und seine Vorteile besprechen und Anleitungen zur Verwendung unseres Patchsets geben. Darüber hinaus wird der Vortrag unseren Ansatz zum Testen von Low-Level-Software behandeln und dabei die technischen Details und Methoden hervorheben. Diese Sitzung richtet sich an Benutzer und Entwickler, die ihr Virtualisierungssetup unter Linux verbessern möchten. about this event: https://chemnitzer.linux-tage.de/2024/de/programm/beitrag/148 </itunes:summary> <itunes:duration>00:45:10</itunes:duration> </item> <item> <title>::1 (clt24)</title> <link>https://media.ccc.de/v/clt24-243-1</link> <description>Bei ::1 ist noch alles in Ordnung.

Ob für Gaming, als mobile Workstation oder primärer Rechner – es gibt kaum noch einen Haushalt, in dem kein Laptop genutzt wird. Mit der Mobilität ergeben sich aber nicht nur Vorteile, auch die Risiken sind im Vergleich zum stationären PC mehr geworden. Schutzmechanismen wie Kensington-Schlösser, Blickschutzfilter und Datenverschlüsselung können helfen, Risiken zu minimieren. Laufende Dienste, zum Beispiel für ssh- oder VNC-Zugang, werden dadurch jedoch nicht geschützt. Hier kann mithilfe einer Kombination aus NetworkManager und firewalld eine flexible Konfiguration geschaffen werden, die mir je nach Ort den Zugriff auf Dienste erlaubt beziehungsweise verweigert. Der NetworkManager erstellt für jedes Netzwerk eine eigene Verbindung. Diese lässt sich an eine firewalld-Zone binden. Diese Zonen bestehen aus Firewallregeln und lassen sich einfach auf die eigenen Bedürfnisse anpassen. In diesem Vortrag werden nicht nur die technischen Hintergründe verständlich erklärt, sondern auch gezeigt, wie je nach Netzwerkverbindung die jeweils passenden Firewallregeln automatisch aktiviert werden. about this event: https://chemnitzer.linux-tage.de/2024/de/programm/beitrag/152 </description> <enclosure url="https://cdn.media.ccc.de/events/clt/2024/h264-hd/clt24-79-deu-Flexible_Firewall_mit_NetworkManager_und_firewalld_hd.mp4" length="214958080" type="video/mp4"/> <pubDate>Sat, 16 Mar 2024 12:30:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/clt/2024/h264-hd/clt24-79-deu-Flexible_Firewall_mit_NetworkManager_und_firewalld_hd.mp4?1710599430</guid> <dc:identifier>35f63ddc-2323-5dd9-b5a9-aee0cd830851</dc:identifier> <dc:date>2024-03-16T12:30:00+01:00</dc:date> <itunes:author>Florian Winkler</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>clt24, 79, 2024, Vortrag</itunes:keywords> <itunes:summary>Laptops, früher noch teuer und leistungsschwach, haben heute oft den klassischen PC abgelöst.

Das klingt logisch, aber die damit verbundenen Konsequenzen sind nicht immer auf den ersten Blick ersichtlich. Denn in den meisten Fällen reicht es eben nicht aus, einfach nur ein TPM per SPI/I2C anzuschließen.

Als Beispiel dient ein moderner NXP i.MX8M ARMv8a SoC, anhand dessen der Verified-Boot Ablauf erklärt wird.

In Zeiten des Online-Shoppings sind die Menschen besorgt, ob Online-Shops ihre Daten vernünftig behandeln und sichern. Online-Shops können über gängige Web-Schwachstellen wie SQL-Injections, XSS usw. angegriffen werden. Dadurch könnten Angreifer persönliche Informationen wie Name, Adresse und Bankdaten kopieren. Wir haben jedoch eine noch einfachere - und bisher unbeachtete - Möglichkeit gefunden, an die persönlichen Daten der Kunden von Online-Shops zu gelangen - ohne irgendwelche Schwachstellen auszunutzen. Da fast alle online bestellten physischen Waren von Paketdiensten ausgeliefert werden, haben wir das Tracking der wichtigsten Akteure im deutschen Paketmarkt analysiert. Durch die Verwendung öffentlich zugänglicher Daten und trivialer Statistik konnten wir Empfängerinformationen (Name, Adresse) schnell und in großer Zahl ermitteln. Dabei war es bei einigen Diensten sogar möglich, die Zustellung von Paketen zu beeinflussen. Gezielte Angriffe könnten dazu führen, dass Adressen und Einkaufsverhalten von Politikern und anderen Personen des öffentlichen Lebens aufgedeckt werden. Auch die Identifizierung von Kunden bestimmter Geschäfte ist denkbar. Die Art und Weise, wie die Sendungsnummern generiert werden, ermöglicht es uns nämlich, gezielt bestimmte Online-Shops anzugreifen. Während unserer Recherche haben wir mehrere Paketdienste kontaktiert (Responsible Disclosure), was zu einigen Verbesserungen führte. Einige Disclosure-Prozesse hatten schnelle und effektive Maßnahmen zur Folge und können als gute Beispiele dienen, während andere noch Raum für Optimierungen bieten. Wir werden auch darüber reden, wie Disclosure-Prozesse besser ablaufen können, und werden ein paar unterhaltsame Ereignisse darstellen. Wir kommen zu dem Schluss, dass Paketdienste eine - vielleicht - unterschätzte Gefahr für die Privatsphäre darstellen. Anstatt zahllose Online-Shops anzugreifen, ist der Missbrauch fehlerhafter Prozesse bei den wenigen marktbeherrschenden Paketzustelldiensten, die von fast allen Shops genutzt werden, ein ziemlich effizienter Weg, um an Adressen und in einigen Fällen an die Möglichkeit zu gelangen, in den Zustellprozess einzugreifen. In unserem Vortrag werden wir den statistischen Ansatz zum Brechen der Authentifizierung für die Paketverfolgung, die zugrundeliegenden Probleme, (negative und positive) Highlights aus den Disclosure-Prozessen und natürlich die Auswirkungen auf die Privatsphäre aufzeigen, die dies gehabt haben könnte und noch haben kann. about this event: https://winterkongress.ch/2024/talks/ich_wei_was_du_letzten_sommer_bestellt_hast/ </description> <enclosure url="https://cdn.media.ccc.de/events/dgwk/2024/h264-hd/import-56194-deu-Ich_weiss_was_du_letzten_Sommer_bestellt_hast_hd.mp4" length="174063616" type="video/mp4"/> <pubDate>Sat, 02 Mar 2024 14:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/dgwk/2024/h264-hd/import-56194-deu-Ich_weiss_was_du_letzten_Sommer_bestellt_hast_hd.mp4?1710555335</guid> <dc:identifier>9678e396-7d41-4379-8ec0-7d8004d21804</dc:identifier> <dc:date>2024-03-02T14:00:00+01:00</dc:date> <itunes:author>Florian Bausch, Dennis Kniel</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>import, 56194, 2024, Netzwerke, Security, Hard- & Software</itunes:keywords> <itunes:summary>Dieser Vortrag beschreibt, wie wir fehlerhafte Prozesse in der Paketverfolgung der meisten deutschen Paketzustelldienste entdeckt haben, wie diese auf unsere Erkenntnisse reagiert haben und warum dies sehr wahrscheinlich auch deine Privatsphäre betrifft.

Wir kommen zu dem Schluss, dass Paketdienste eine - vielleicht - unterschätzte Gefahr für die Privatsphäre darstellen. Anstatt zahllose Online-Shops anzugreifen, ist der Missbrauch fehlerhafter Prozesse bei den wenigen marktbeherrschenden Paketzustelldiensten, die von fast allen Shops genutzt werden, ein ziemlich effizienter Weg, um an Adressen und in einigen Fällen an die Möglichkeit zu gelangen, in den Zustellprozess einzugreifen. In unserem Vortrag werden wir den statistischen Ansatz zum Brechen der Authentifizierung für die Paketverfolgung, die zugrundeliegenden Probleme, (negative und positive) Highlights aus den Disclosure-Prozessen und natürlich die Auswirkungen auf die Privatsphäre aufzeigen, die dies gehabt haben könnte und noch haben kann. about this event: https://winterkongress.ch/2024/talks/ich_wei_was_du_letzten_sommer_bestellt_hast/ </itunes:summary> <itunes:duration>00:40:48</itunes:duration> </item> <item> <title>Google, der Meta-Monopolist (dgwk2024)</title> <link>https://media.ccc.de/v/dgwk2024-56189-google-der-meta-monopolis</link> <description>Google ist der heimliche Herrscher des Internets: Es kontrolliert den marktführenden Browser, das verbreitetste Mobile-OS, die damit verknüpfte Google Cloud, die dominanten Suchmaschinen und Videoplattformen sowie die Werbeplattform, um die man nicht herumkommt.

Ich zeige, wie man sich mit diesen Werkzeugen eine einfache und sichere Datensicherungsstrategie einrichtet und dazu kostenlos verfügbaren Speicherplatz z.B. via Google, Dropbox oder Magenta nutzt. Selbstgehostete Server mit SSH/FTP/SFTP-Zugang o.ä. können natürlich auch genutzt werden. Mit rclone können Daten nicht nur synchronisiert werden, sondern es kann auch Cloud-Storage wie eine Festplatte eingemountet werden.

Zu vielen Daten gehört eine Adresse, ein Straßenname, eine Postleitzahl und ein Land. Aber wo genau ist diese Adresse? Und was befindet sich in der Nähe dieser Adresse? Um diese Fragen zu lösen, müssen Adressen in Geokoordinaten aufgelöst werden. Je besser und genauer die Adressdaten sind, desto größer ist die Chance, die richtigen Koordinaten zu finden. Dieser Vortrag zeigt, wie Adressen mithilfe von OpenSteetMap-Daten aus der Datenbank heraus mithilfe von Python-Funktionen aufgelöst werden können. Wir sprechen auch über die Genauigkeit der Daten, indem wir die Ergebnisse verschiedener Adressformate mit bekannten Koordinaten vergleichen. about this event: https://chemnitzer.linux-tage.de/2024/de/programm/beitrag/126 </description> <enclosure url="https://cdn.media.ccc.de/events/clt/2024/h264-hd/clt24-126-deu-Fuege_Geokoordinaten_zu_deinen_Adressen_in_PostgreSQL_hinzu_hd.mp4" length="236978176" type="video/mp4"/> <pubDate>Sat, 16 Mar 2024 12:30:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/clt/2024/h264-hd/clt24-126-deu-Fuege_Geokoordinaten_zu_deinen_Adressen_in_PostgreSQL_hinzu_hd.mp4?1710600432</guid> <dc:identifier>05a3b34b-338f-5e86-b71e-8ba2b7019bc3</dc:identifier> <dc:date>2024-03-16T12:30:00+01:00</dc:date> <itunes:author>Andreas Scherbaum</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>clt24, 126, 2024, Vortrag</itunes:keywords> <itunes:summary>Geolokalisierungsdaten sind ein heißes Thema. Zu vielen Daten gehört eine Adresse, ein Straßenname, eine Postleitzahl und ein Land. Aber wo genau ist diese Adresse? Und was befindet sich in der Nähe dieser Adresse? Um diese Fragen zu lösen, müssen Adressen in Geokoordinaten aufgelöst werden. Je besser und genauer die Adressdaten sind, desto größer ist die Chance, die richtigen Koordinaten zu finden.

Mit dieser können die diskriminierenden Abgründe, die «dunklen Ecken» von GPT und Konsorten erkundet werden. Um den Einstieg ins Testen zu erleichtern, schlagen wir ein paar entlarvende Prompts vor, die man einfach anklicken kann. Die Nutzer:innen können dann selber ausprobieren, ob sie damit sexistische oder rassistische Texte und Bilder provozieren können. Der Bias-Tester soll sich noch weiterentwickeln – in Zukunft soll er auch Vergleiche zwischen verschiedenen Modellen erlauben. Dark Corners: Willkommen zum Vorurteile-Tester KI hat Vorurteile In den aktuellen generativen KI-Modellen (beispielsweise ChatGPT oder DALL·E) stecken nicht nur riesige Mengen an Daten, in ihnen stecken auch unsere eigenen Vorurteile und unsere diskriminierenden Strukturen. Man könnte auch sagen: die KI hat die Machtverhältnisse der – westlichen – Gesellschaft souverän übernommen, sie hat sie gelernt. Und reproduziert sie nun dementsprechend. Für die Ausstellung «Macht» im Vögele Kultur Zentrum in Pfäffikon SZ hat die Turing Agecny eine Teststation gebaut, mit der die diskriminierenden Abgründe, die «dunklen Ecken» von GPT und Konsorten erkundet werden können. Um den Einstieg ins Testen zu erleichtern, schlagen wir ein paar entlarvende Prompts vor, die man einfach anklicken kann. Die Besuchenden können dann selber ausprobieren, ob sie damit sexistische oder rassistische Texte und Bilder provozieren können. Sie dürfen auch selber kreativ werden! Vielleicht kommen Ihnen weitere Szenerien in den Sinn, um dunkle Ecken in den Sprach- und Bildmodellen auszuleuchten. AI Bias – was ist das? Künstliche Intelligenz kann all die Dinge die sie kann nur weil sie auf die jeweilige Funktion hin "trainiert" worden ist, wie das im Fachjargon heisst. Dieses Training ist eine mathematisch komplexe Sache, aber entscheidend dabei ist: Grundlage des Trainings sind Unmengen an Daten. Und diese sind zumeist menschgemacht. Bei grossen Text-KIs also: Terabytes und Terabytes an Texten, die überall da gesammelt werden, wo sie frei verfügbar sind. Manche sagen auch: für das Training hätten sich ChatGPT und Konsorten "das komplette Internet" einverleibt. In diesen Daten steckt viel menschliches Wissen, aber was auch drin steckt: viele Vorurteile, viel gesellschaftliche Ungleichheit. Diese sogenannten "Biases" tauchen in den Sprachausgaben der KI dann wieder auf, manchmal versteckt, manchmal auch offensiv offen. Da ist die KI nicht besser, nicht klüger, nicht fairer als wir. Ausserdem drängt sich die Frage auf: welcher Teil der Welt ist dominant im Internet vertreten – und wofür ist das Internet blind? Funktionieren und urteilen Maschinen objektiver und unvoreingenommener als Menschen, können sie "neutral" sein? Das hätten wir gern. Und es mag vielleicht bei einem Kamera-Bild noch halbwegs stimmen, das eine Szenerie zeigt "wie sie ist", im Gegensatz zur unverlässlichen Erinnerung eines Zeugen. Aber bei KI läuft diese Hoffnung ins Leere. Die KI trifft ihre Entscheidungen nicht nach einem maschinell-logischen Raster, sondern nach Wahrscheinlichkeit. Und was sie als mehr oder weniger wahrscheinlich erachtet hat sie allein anhand menschlicher Beispiele gelernt. Es gibt zwar Versuche, KIs die menschlichen Vorurteile ganz gezielt abzugewöhnen oder sie mit Filtern zu neutralisieren. Zum Beispiel bei automatisierten Bewerbungsverfahren: Können Kandidatinnen von einer KI womöglich fairer ausgewählt werden? Nämlich anhand tatsächlicher Qualitäten und nicht aufgrund von Geschlecht oder ausländisch klingendem Nachnamen? So etwas wird gerade intensiv erforscht. Leider zeigt sich: Die Macht der Trainingsdaten ist gross, die "perfekt vorurteilsfreie" Maschine wird wohl eine Illusion bleiben. Denn am Schluss sind alle Flick-Versuche auch wieder subjektiv, jeder Filter zeigt auch wieder ein Wertsystem auf. Welche Ismen hat die KI von uns gelernt? Und wie offensichtlich reproduziert sie sie? about this event: https://winterkongress.ch/2024/talks/dark_corners_eine_bias_testing_station/ </description> <enclosure url="https://cdn.media.ccc.de/events/dgwk/2024/h264-hd/import-56200-deu-Dark_Corners_-_eine_Bias_Testing_Station_hd.mp4" length="427819008" type="video/mp4"/> <pubDate>Sat, 02 Mar 2024 13:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/dgwk/2024/h264-hd/import-56200-deu-Dark_Corners_-_eine_Bias_Testing_Station_hd.mp4?1710031783</guid> <dc:identifier>cc6b0d9e-01a7-4eaf-844d-64bc4e3851f5</dc:identifier> <dc:date>2024-03-02T13:00:00+01:00</dc:date> <itunes:author>Roland Fischer, Robert Salzer</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>import, 56200, 2024, Ethik, Wissenschaft, Kultur & Gesellschaft</itunes:keywords> <itunes:summary>Dark Corners ist eine von der Turing Agency gebaute Teststation.

Sie beleuchten die fragwürdigen Geschäfte der Intellexa-Allianz, einem Zusammenschluss von Überwachungsunternehmen, die von Europa aus mächtige Cyberwaffen in die ganze Welt exportierte.

Die VIM-Gesetzgebung über die Vermittlung von Gütern zur Internet- und Mobilfunküberwachung, wird kaum aktiv angewendet. Letzteres kritisieren Expert:innen mit Blick auf den Fall Intellexa. Und die Sicherheitsdienste? Die schweigen, wie üblich. Wer die Skandale mit Spionage- und Überwachungstechnologie der letzten Jahre eim Blick hat weiss: Das ist ein Problem.

Bilder, die nur einen geringen oder gar keinen wirtschaftlichen Wert haben, sollen plötzlich 1'000 Euro und mehr kosten: Wie funktioniert diese wundersame Geldvermehrung? Wieso soll plötzlich deutsches Recht gelten? Wie sollen schweizerische Betroffene reagieren? Im Vortrag wird mit Beispielen aus der Praxis erklärt, wie die deutsche Abmahnindustrie funktioniert und wieso die Schweiz ein attraktives Ziel für deutsche Abmahnanwälte ist. Erklärt werden unter anderem die finanziellen und rechtlichen Anreize für deutsche Abmahner und ihre Rechtsanwälte. Das Publikum lernt, wie Abmahnungen von Anfang an vermieden werden können. Für den Fall, dass eine Abmahnung eintrifft, erfährt das Publikum, wie man richtig reagiert. Gleichzeitig wird dem Publikum vermittelt, wie das Urheberrecht bei Bildern funktioniert, auch grenzüberschreitend. about this event: https://winterkongress.ch/2024/talks/wundersame_geldvermehrung_bilder_abmahnungen_aus_deutschland/ </description> <enclosure url="https://cdn.media.ccc.de/events/dgwk/2024/h264-hd/import-56177-deu-Wundersame_Geldvermehrung_Bilder-Abmahnungen_aus_Deutschland_hd.mp4" length="279969792" type="video/mp4"/> <pubDate>Fri, 01 Mar 2024 22:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/dgwk/2024/h264-hd/import-56177-deu-Wundersame_Geldvermehrung_Bilder-Abmahnungen_aus_Deutschland_hd.mp4?1709868363</guid> <dc:identifier>8e3740db-4386-4d93-8d60-a4a74c6a040d</dc:identifier> <dc:date>2024-03-01T22:00:00+01:00</dc:date> <itunes:author>Martin Steiger</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>import, 56177, 2024, Recht & Politik</itunes:keywords> <itunes:summary>Bilder-Abmahnungen aus Deutschlang gelangen in grosser Zahl in die Schweiz: Wer ein Bild auf seiner Website oder seinem Social-Media-Profil veröffentlicht hat, erhält plötzlich Anwaltspost aus Deutschland: Abmahnanwälte fordern aggressiv und mit kurzen Fristen, dass viel Geld bezahlt und eine Unterlassungserkärung abgegeben wird.

Für den Fall, dass eine Abmahnung eintrifft, erfährt das Publikum, wie man richtig reagiert. Gleichzeitig wird dem Publikum vermittelt, wie das Urheberrecht bei Bildern funktioniert, auch grenzüberschreitend. about this event: https://winterkongress.ch/2024/talks/wundersame_geldvermehrung_bilder_abmahnungen_aus_deutschland/ </itunes:summary> <itunes:duration>00:46:14</itunes:duration> </item> <item> <title>Datenethik in der Praxis: Von Anonymisierung zu operativer Datengovernance (dgwk2024)</title> <link>https://media.ccc.de/v/dgwk2024-56181-datenethik-in-der-praxis</link> <description>In unserem Vortrag erläutern wir, wie die Datengenossenschaft Posmo mit einem starken Datengovernanceprozess die ethische Nutzung der ihr angetrauten Daten gewährleistet.

Interessierten Abnehmern stellen wir diese Daten zur Lösung von gesellschaftlichen Herausforderungen im Bereich nachhaltige Mobilität und Stadtplanung unter Einhaltung strikter ethischer Richtlinien zur Verfügung. Die Privatsphäre der Datensubjekte zu schützen steht für uns an erster Stelle. Eine zentrale Rolle spielen dabei technische Anonymisierungsverfahren.

Um die Frage zu beantworten, ob ein echtes Fusionskraftwerk bald wirtschaftlich Energie produzieren könnte, betrachten wir den Fusionsreaktor von den Grundlagen physikalischer Prozesse der Fusion bis zum Aufbau und den technischen und politischen Problemen beim Bau eines Fusionsreaktors, der ja am Ende diesen Prozess auf der Erde durchführen soll, um – so hofft man – nachhaltig an große Mengen elektrischer Energie zu gelangen. Um stabile Fusion zu erreichen, sind ein besonders heißes Plasma und starker magnetischer Einschluss wichtig. Dabei gibt es zwischen den Modellen Stellarator und Tokamak Unterschiede, jeweils mit ihren eigenen Vorzügen und Nachteilen. Die betrachteten Modelle verwenden verschiedene Heizmethoden, um das Plasma über Strom, Strahlung und Teilcheneinschuss heizen. Um einen ausreichend starken magnetischen Einschluss zu erreichen, sind nicht nur sehr starke und supraleitende Spulen vonnöten, sondern auch spezielle Vorrichtungen, welche das Plasma in Schichten aufteilen. Hier spielt auch die Turbulenz (der Übergang von geordneten, in chaotische Ströme) eine große Rolle. Wir wollen die theoretischen Aspekte anhand von den Fusionsexperimenten JET, ITER und Wendelstein 7x betrachten und im praktischen Kontext mit neueren Ansätze seitens Firmen außerhalb der Grundlagenforschung vergleichen, bei denen aus Forschersicht nebensächliche Details wie ingenieurtechnische Sicherheitsmaßnahmen und Beschaffung und Entsorgung der nötigen Grund- und Abfallstoffe große Bedeutung zufallen. Daher gehört zu einer realistischen Abwägung der Praktikabiliät – kurzum, ob uns die Fusion vor der Klimakatastrophe retten kann – auch eine Betrachtung des politischen Einflusses und allgemeiner finanzieller Schwierigkeiten der Grundlagenforschung zur Fusion und deren Umsetzung und die Übergabe an die Privatwirtschaft. – Der Referent bringt Erfahrungen aus mehreren Praktika am IEK 4 des Forschungszentrums Jülich und das IPP Greifswald mit, wo das Fusionsexperiment Wendelstein 7x steht. about this event: https://c3voc.de </description> <enclosure url="https://cdn.media.ccc.de/contributors/berlin/datengarten/h264-hd/datengarten-110-deu-Datengarten_110_hd.mp4" length="260046848" type="video/mp4"/> <pubDate>Wed, 28 Feb 2024 20:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/contributors/berlin/datengarten/h264-hd/datengarten-110-deu-Datengarten_110_hd.mp4?1709231993</guid> <dc:identifier>456fb60c-5ce7-11e8-be47-1fb2912eb8110</dc:identifier> <dc:date>2024-02-28T20:00:00+01:00</dc:date> <itunes:author>Momo Jaeckel</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>datengarten, 110, 2024</itunes:keywords> <itunes:summary>Um die Energiewende voranzutreiben, wird die Kernfusion oft als das ultimative Kraftwerk und als die Lösung all unserer energetischen Probleme angesehen, dennoch blieb diese Technologie seit 1960 stets “dreißig Jahre entfernt”.

Sie verwenden einfach Bleistifte. So oder so ähnlich lautet die Urban Legend zum Space Pen. In diesem Petit Foo untersucht sirgoofy was an der Geschichte dran ist und ob Bleistifte im Weltraum eine gute Idee sind. about this event: https://chaospott.de/ </itunes:summary> <itunes:duration>00:08:12</itunes:duration> </item> <item> <title>Basisbeveiliging / Internet Cleanup Foundation - State of the map (hackerhotel2024)</title> <link>https://media.ccc.de/v/hackerhotel-2024-112-basisbeveiliging-internet-cleanup-foundation-state-of-the-map</link> <description>An overview of the new maps and new metrics added in 2023, and what it did.

It's a very technical hobby, with a lot of variation. Much more than an Old Man talking on the radio all day. As a licensed HAM you have access to many frequency bands - HF, these are low frequencies that can travel 1000ths of kilometers without repeater - But also frequencies close to 'commercial' products, a ham could use LoRa 433MHz with over 100W to see what that does. - Also on 2.4GHz and 5GHz there is a HAM radio frequency band next to the WiFi band that can be used with much power. - There are a bunch of satellites that can be used for (data) communication as well.

While there are many benefits, the security implications are far less understood than the mechanical systems. Jan-Willem collects and researches electronic safe locks and will share his thoughts. From dumping chips with lasers to locks which can be opened with ketchup. We use safes to protect our valuables from threats. We trust these systems to keep the assets safe. Mechanical combination locks can be quite cumbersome to operate, and don't have the benefits including auditing, remote access, multi-user, time lock, and much more. But how the additional electronics impacts the security of the safe isn't widely understood. This talk goes into researching the security of electronic safe locks, from reverse engineering known attacks, to learning from scratch. For example, we used laser fault injection to read out the memory of several chips to analyze the code looking for bugs and back doors.

When home movies on 8mm film were king, there was a format war between Kodak's Super 8 and Fuji's Single 8.

In this talk we will go over mapping out our personal tech stack and start identifying any threats that could be useful to help prevent stalking and harassment, or at least be aware of the risks you encounter so you can make informed choices about data that you share. In the presentation I’ll give an example of a basic threat modeling that can be applied to our personal digital footprint to help improve privacy and protect yourself against nosey governments and digital stalking. We start with creating an overview of all apps, services and accounts that we use and contain personal information, focusing on those that can be exploited for stalking or bullying purposes. From there we will apply threat modeling methods, mainly persona non grata, to identify how they can be exploited by malicious actors. Either working from publicly shared information or who might have gained access to private details in legitimate or illegitimate ways. about this event: https://pretalx.hackerhotel.nl/hackerhotel-2024/talk/JTUNBY/ </description> <enclosure url="https://cdn.media.ccc.de/events/hackerhotel/2024/h264-hd/hackerhotel2024-93-eng-Threat_Modeling_for_Privacy_and_against_Stalkers_hd.mp4" length="160432128" type="video/mp4"/> <pubDate>Sat, 10 Feb 2024 16:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/hackerhotel/2024/h264-hd/hackerhotel2024-93-eng-Threat_Modeling_for_Privacy_and_against_Stalkers_hd.mp4?1707667821</guid> <dc:identifier>d4fc9bb0-af2a-5c1f-adcc-80c1c35e2a5c</dc:identifier> <dc:date>2024-02-10T16:00:00+01:00</dc:date> <itunes:author>Dany</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>hackerhotel2024, 93, 2024, Talks</itunes:keywords> <itunes:summary>When we talk about tech stacks we usually think about big organizations running systems, but in the current day and age we too have a large digital footprint.

Cryptography is not only essential in our modern-day lives, but it has been for thousands of years. After some historical context, we will dive into some modern ciphers like DES, AES, RSA and ECC. I will show you how they work (using simple to understand high-school math and pretty pictures) and how to use them. We will then see how quantum computers are bad for cryptography and show techniques that can counter that.

Pre-talk disclaimer: the provided explanations are very high-level and leave out details that make the ciphers actually secure. **DO NOT USE THEM IN YOUR PROJECTS!** about this event: https://pretalx.hackerhotel.nl/hackerhotel-2024/talk/B7BL3K/ </itunes:summary> <itunes:duration>01:00:02</itunes:duration> </item> <item> <title>WOOt does the government do?

This cinderella story is about how a big vendor rolled its own algorithm to "encrypt" its firmware images to deter poor hackers like us from fiddling around and potentially uncover flaws. But what if your motive is not to uncover potential flaws, but simply to agnostically fingerprint devices left vulnerable on the internet? Join us into a semi-deepdive of reverse engineering the Fortigate firmware "encryption" to satisfy our own curiosity, but also to make the web that little bit more secure by fingerprinting vulnerable devices in a non-obtrusive manner with the endgoal of notifying the related parties. This talk will go into the process of reverse engineering the Fortigate firmware images with the purpose of developing a non-obtrusive version identification that can be used to fingerprint device firmware versions on the internet, this in turn can be used to notify the related party. Next to a technical deep dive the audience will be presented with a set of questions and thoughts on the topic of encrypting such firmware devices and if this really is the way to go for big vendors, or if these things are only making matters worse by limiting the scope to not just the "bad" people, but also the "good" people. about this event: https://pretalx.hackerhotel.nl/hackerhotel-2024/talk/QB3Z87/ </description> <enclosure url="https://cdn.media.ccc.de/events/hackerhotel/2024/h264-hd/hackerhotel2024-114-eng-Crypterella_Stories_Fortigate_hd.mp4" length="154140672" type="video/mp4"/> <pubDate>Sun, 11 Feb 2024 14:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/hackerhotel/2024/h264-hd/hackerhotel2024-114-eng-Crypterella_Stories_Fortigate_hd.mp4?1707670029</guid> <dc:identifier>1a004edb-8d92-5a49-911a-fd1739e0159c</dc:identifier> <dc:date>2024-02-11T14:00:00+01:00</dc:date> <itunes:author>axel</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>hackerhotel2024, 114, 2024, Talks</itunes:keywords> <itunes:summary>We all love bedtime stories, and these stories are even better when they turn into reality.

The proliferation of content generated by artificial intelligence (AI) is just beginning. Recent years have seen online accounts, run by bots, create fake news articles, divisive social media posts, fraudulent product reviews, and more. As mainstream access to AI tools spreads, the opportunities to use the technology for malicious purposes are on the rise. Nico Dekens, a renowned open source intelligence professional, has noticed recurring patterns in content created using artificial intelligence. He demonstrates how he has used OSINT tools and even basic search engines to locate and identify online accounts that appear to be using autogenerated website content, social media posts, reviews, and hate speech. Investigative approaches and techniques are covered, including a list of string text that can be easily searched to locate these types of accounts. There is also a detailed example for generating high-quality deep fake photos using Midjourney. The author takes an ethical stance on the use of artificial intelligence and advocates for validating online content using OSINT investigative methodology.

Wir beginnen mit einer anschaulichen Erklärung, wie ein NN funktioniert und warum es keine wirkliche Ähnlichkeit mit deinem Gehirn hat. Anschließend schrauben wir die Black Box, wie es so schön heißt, einfach einmal auf: Wie können NN erklärbar gemacht werden? Warum trifft ein Neuronales Netz diese oder jene Entscheidung? Was an der politischen Forderung nach erklärbarer KI ist tatsächlich umsetzbar? Außerdem werden wir sehen, wie NN manchmal schummeln, um eine Vorhersage zu treffen. Im Gegenzug tricksen wir sie auch gezielt aus. Brauchen wir wirklich einen weiteren Vortrag über Künstliche Intelligenz? In den letzten Jahren war das Thema omnipräsent, Bilder werden jetzt generiert, Texte nicht mehr selbst geschrieben und ob ich kreditwürdig bin, prüft auch so eine KI. Und wer weiß, neulich klang der Chat Bot richtig menschlich, vielleicht hat er ja doch ein Bewusstsein. In diesem Vortrag geht es nicht um tolle Errungenschaften von KI-Systemen oder um „30 Prompts, mit denen du noch effektiver bist!“. Dieser Vortrag legt den Grundstein für ein Verständnis von maschinellem Lernen mit dem Ziel, dass du am Ende selbst die aktuellen Entwicklungen einschätzen kannst: Übertrumpfen Neuronale Netze irgendwann wirklich den Menschen? Oder können sie im Grunde gar nichts und sind massiv fehleranfällig? Und die Frage aller Fragen: Hat künstliche Intelligenz ein Bewusstsein oder steht kurz davor, eines zu entwickeln?

Ist es gerechtfertigt, dass man zum Einrichten einer Simulationssoftware den Kundendienst und einen Abschluss in Systemintegration braucht? Kann ich nicht einfach mit Games wie GTA und BeamNG.drive forschen? Genau vor diesen Fragen standen wir beim Aufbau unseres IMIS E-Fahrsimulators vor 5 Jahren.

Systems created by humans will contain flaws. In order to shine a light on these flaws, you can use a technique called threat modelling. There are hundreds if not thousands of different threat modelling methods that can be used to tease apart the structure of a system in search for security issues. In this talk, we will cover the key principles behind these methods, enabling anyone to study and mend the architecture of a system. In covering the basics, we will also critically reflect on the direction of much research and practice, sketching the relevance of threat modelling for addressing contemporary challenges and highlighting the role that you can play in making a security impact. *As preparation for or follow-up of this talk, [see this recorded training](https://archive.org/details/getting_started_with_threat_modelling).* *The recorded training can be watched either before or after the live talk.

Über die aktuelle Situation, das widerständige Waldleben und warum Hambi bleiben muss. Der Hambacher Wald aka Hambi ist ein wunderschöner 12.000 Jahre alter Wald, der seit 2012 besetzt ist. Seit der letzten Räumung 2018, als die Besetzer*innen es geschafft haben, die Rodung der verbleibenden Bäume zu verhindern, steht dort eine der größten autonomen Zonen Europas. Der Hambi bleibt ein Ort des Widerstandes gegen den fossilen Kapitalismus weltweit und für den Aufbau eines alternativen, herrschaftskritischen Zusammenlebens. Doch momentan bedrohen mehrere Faktoren das Überleben des Waldes (wie die geplante Erweiterung des Tagebaus und die Pläne der Bezirksregierung Köln). In diesem Vortrag werden wir übers Waldleben sprechen, über die aktuelle Situation, darüber warum Hambi bleiben muss und was wir dafür tun können. Danach wird es Gelegenheit zu Austausch und Vernetzung mit Menschen aus dem Wald geben.

Was genau das ist und welche Bedürfnisse hinsichtlich der Barrierefreiheit bereits mit dem Ansatz befriedigt werden können und wo noch die richtigen Mechanismen fehlen, wird Inhalt dieses Talks. about this event: https://events.ccc.de/congress/2023/hub/event/rian-responsive-to-individual-accessibility-needs/ </itunes:summary> <itunes:duration>01:46:08</itunes:duration> </item> <item> <title>Lützerath Lebt!

Die Gruppe *Konstruktive Digitale Diskussionskultur* (KDDK) hat das Ziel, sich sytematisch (d.h. über die individuelle Ebene hinaus) und lösungsorientiert mit dem Problem zu befassen. Der Vortrag stellt die Problemwahrnehmung und mögliche Lösungsansätze aus Sicht der Gruppe vor. Wir als demokratische Gesellschaft haben ziemlich große Herausforderungen vor uns (Klima, Ressourcen, Verteilung, gesellschaftliche Normen, ...). Diese akzeptabel zu lösen, wird ziemlich schwierig, wenn wir nicht “vernünftig” miteinander diskutieren können und auf Basis solcher Diskussionen dann gut informierte Entscheidungen treffen. Leider läuft es aktuell ganz anders, insbesondere im digitalen Raum: Bei kontroversen Themen findet sachlicher Austausch gut begründeter Argumente viel seltener statt als Irreführung, Polemik und Beleidigungen bis hin zu harter digitaler Gewalt. Bezugsloses Aneinander-Vorbeireden oder das Versanden der Diskussion sind dann zwar noch vergleichsweise harmlose Verläufe – sie helfen aber beim Finden von Problemlösungen auch nicht. Oft werden diese Probleme auf indivdueller Ebene thematisiert aber ein zivilgesellschaftlicher bzw. aktivistischer Rahmen, um sie auf Systemebene anzugehen fehlte bislang. Deswegen hat sich im Sommer 2023 eine Gruppe gegründet, die das ändern möchte. Der Vortrag stellt die Gruppe *Konstruktive Digitale Diskussionskultur* (KDDK) auf Basis ihres zwölf Thesen umfassenden Positionspapiers und anhand passender Beispiele vor. Dabei werden u.a. folgende Fragen behandelt: - Worin besteht das Problem mit der Diskussionskultur? - Warum ist das sehr kritisch? - Wie können Schritte in Richtung einer Lösung aussehen? about this event: https://events.ccc.de/congress/2023/hub/event/konstruktive-digitale-diskussionskultur-kddk/ </description> <enclosure url="https://cdn.media.ccc.de/events/fireshonks/h264-hd/37c3-57963-deu-Konstruktive_Digitale_Diskussionskultur_KDDK_hd.mp4" length="142606336" type="video/mp4"/> <pubDate>Thu, 28 Dec 2023 18:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/fireshonks/h264-hd/37c3-57963-deu-Konstruktive_Digitale_Diskussionskultur_KDDK_hd.mp4?1705244976</guid> <dc:identifier>8ed1e5de-78ef-563c-9840-807bf9a6210b</dc:identifier> <dc:date>2023-12-28T18:00:00+01:00</dc:date> <itunes:author>CarK</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 57963, 2023</itunes:keywords> <itunes:summary>Digital geführte Diskussionen über kontroverse Themen sind oft frustrierend: Sie gleiten ins Unsachliche ab, sie eskalieren, z.T. bis hin zu harter digitaler Gewalt, oder sie versanden ergebnislos.

This technology has global potential to disrupt energy and wastewater systems. Active Living Infrastructure: Controlled Environment (ALICE) is a "living" installation that communicates with microbes in real time by monitoring their electricity production so we can "respond" to them by feeding them with our liquid waste. Drawing together microbial metabolism, data, bioprocessor systems, artificial intelligence, low power electronics and digital displays, ALICE reveals the inner "life" and naturally-organised, imperceptible realm of microbes around us. To hold these digital "conversations" with microbes, ALICE uses the Microbial Fuel Cell (MFC) as a communications platform. MFCs are an organic energy source powered by microbes which facilitate contact between humans and microbes through electrical exchanges. The collected and analysed data can tell us about household resources, as microbes can give us information about our consumption, and reveal what we discard in our waste streams—while also powering our homes and, ultimately, cities. https://alice-interface.eu Come and see us in Null Sector! about this event: https://c3voc.de </description> <enclosure url="https://cdn.media.ccc.de/events/emf/2022/h264-hd/emf2022-307-eng-Pee_is_Powerful_From_artwork_to_new_world_infrastructures_with_ALICE_hd.mp4" length="286261248" type="video/mp4"/> <pubDate>Sat, 04 Jun 2022 18:50:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/emf/2022/h264-hd/emf2022-307-eng-Pee_is_Powerful_From_artwork_to_new_world_infrastructures_with_ALICE_hd.mp4?1704586429</guid> <dc:identifier>4834a4b1-8f78-55de-81c6-3f99416da54c</dc:identifier> <dc:date>2022-06-04T18:50:00+02:00</dc:date> <itunes:author>Julie Freeman, Rachel Armstrong, Ioannis Ieropoulos</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>emf2022, 307, 2022</itunes:keywords> <itunes:summary>Join the conversation with Professors Rachel Armstrong and Ioannis Ieropoulos, and artist Julie Freeman, to hear about how the ALICE artwork is a springboard for thinking about a new infrastructure that encompasses nomadic lifestyles, smart plumbing, resource autonomy - moving beyond fossil fuels and working with natural energy flows.

In this talk I will introduce the basics of railway signalling, and look at how it has evolved over time - often in response to accidents and near-misses. You will find out how a single stray wire caused an accident that killed 35 people, why leaves on the line cause such a problem for the railways, and how signalling systems are designed to deal with the inevitable human error. Working from the early days of the railway to the present (and future), the talk will take you through a number of accidents, their causes and the improvements that were made after the accidents.

After working on container ships as an engineer in the mid-2000s, it seemed every more unlikely. We didn't have a full-time Internet connection and all the vital systems were truly air-gapped. But things have changed - ships are becoming more and more connected and complex. As a result, 15 years later, I found myself sat in my pants on the sofa with the ability to control the steering on one of the world's largest cruise ships. We've been able to brick every PLC across tens of oil rigs, pay for food as the captain, and write rude words on the side of the ship. To get to this point, we had to go on a learning voyage across tens of different vessels, including offshore support tugs, super yachts, oil rigs and container ships. Join me on a whistle stop tour of what's on a ship, how it's all connected together, what threats there are and how we find the vulnerabilities.

The scrapyards are now filled with slightly broken EVs and Hybrid cars, and almost no one knows what to do with them. As a result the parts they are made from are very affordable and available for repurposing and hacking into your own projects. The project is far from complete so there is nothing to bring to the show as I was hoping but there is lots to talk about and discuss regarding the state of play of hacking scrapped and discarded power inverters. The motorbike project uses a battery from a BMW i3 electric car, the motor is from a Mitsubishi Outlander PHEV & the main power inverter for driving the motor is from a hacked Prius running open source firmware with the motorcycle running gear from used motorbikes and a whole host of other bits connected together in ways never intended. The project is only possible using the work done by the EV car hacking community Openinverter.org and their community forum which have reverse engineered the EV power controllers allowing you to run open source firmware on them with some minor alterations. about this event: https://c3voc.de </description> <enclosure url="https://cdn.media.ccc.de/events/emf/2022/h264-hd/emf2022-49-eng-How_Im_building_my_monstrous_electric_motorcycle_from_hacked_scrap_EV_Hybrid_parts_hd.mp4" length="99614720" type="video/mp4"/> <pubDate>Sun, 05 Jun 2022 17:30:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/emf/2022/h264-hd/emf2022-49-eng-How_Im_building_my_monstrous_electric_motorcycle_from_hacked_scrap_EV_Hybrid_parts_hd.mp4?1704592489</guid> <dc:identifier>e3cf2b66-f94b-51b8-b076-a9ee2c4acaa4</dc:identifier> <dc:date>2022-06-05T17:30:00+02:00</dc:date> <itunes:author>Russell Couper</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>emf2022, 49, 2022</itunes:keywords> <itunes:summary>Using end of life or 'scrap' EV & Hybrid parts and opensource firmware I'm making an electric motorbike, having got tired of making dirty diesel ones!

Little IoT devices that brought computers, toys and board game pieces together. In 2011(version one) and 2012 (version 2) a commercial version, Sifteo Cubes, was released, but I was unaware, thinking the dream prototype was just that, a dream not a reality. They passed me by… In 2014, the v2 software was open sourced - the inevitable precursor to failure - and the company bought by Drone/Robotics developer for the obvious design skills of the Sifteo team; they had, after all, reverse engineered and reapplied wireless keyboard controllers into one of the coolest toys ever! So, I came to them late. Too late. By 2015, the server the control software required, along with the online marketplace for the dozen or so games that were made, were long gone. The Sifteo cubes I’d just (re)discovered from a desperate eBay sale were now just useless, battery powered bricks. And they didn’t even click together! But I was stubborn. I wanted them to work.

Damit lädt dein E-Auto oder E-Bike automatisch, wenn eigene PV-Energie verfügbar ist oder der Strom aus dem Netz besonders regenerativ oder günstig ist. Im Gegensatz zu vielen Hersteller-Ökosystemen oder Clouddiensten funktioniert evcc herstellerübergreifend und läuft in deinen eigenen vier Wänden auf deiner Hardware. Dafür bietet die Software Integrationen zu allen gängigen Stromzählern, PV- &amp; Batteriesystemen und Wallboxen an. Hat dein Fahrzeug eine Online-Schnittstelle können noch deutlich mehr smarte Funktionen genutzt werden. Von preisoptimierter Ladeplanung bis hin zum detaillierten Ladelog mit realen Preisen ist einiges möglich. Integrationen zu Smart-Home Systemen und Plugin-Schnittstellen für erweiterte Bedürfnisse sind natürlich auch vorhanden.

Grünen und günstigen Strom laden.</itunes:subtitle> <itunes:summary>evcc ist eine Open-Source-Software, die deine heimische Wallbox steuert. Damit lädt dein E-Auto oder E-Bike automatisch, wenn eigene PV-Energie verfügbar ist oder der Strom aus dem Netz besonders regenerativ oder günstig ist. Im Gegensatz zu vielen Hersteller-Ökosystemen oder Clouddiensten funktioniert evcc herstellerübergreifend und läuft in deinen eigenen vier Wänden auf deiner Hardware. Dafür bietet die Software Integrationen zu allen gängigen Stromzählern, PV- &amp; Batteriesystemen und Wallboxen an. Hat dein Fahrzeug eine Online-Schnittstelle können noch deutlich mehr smarte Funktionen genutzt werden. Von preisoptimierter Ladeplanung bis hin zum detaillierten Ladelog mit realen Preisen ist einiges möglich. Integrationen zu Smart-Home Systemen und Plugin-Schnittstellen für erweiterte Bedürfnisse sind natürlich auch vorhanden.

(emf2022)</title> <link>https://media.ccc.de/v/emf2022-105-the-curious-design-of-the-apollo-guidance-computer</link> <description>The Apollo Guidance Computer (AGC) was a critical element in the success of the Apollo Moon landing programme, and was one of the first digital computers to use the then new technology of integrated circuits. By modern standards, its design has many unusual aspects, such as: - The logic circuits were made entirely from 3 input NOR gates. - Design was split into 24 logic modules, but due to limits on gate/chip count per module, individual gates were sometimes 'borrowed' from unrelated modules. - Shift and rotate operations existed, but were not available during interrupts. - Numerical overflows disabled interrupts. - There was no stack. - Limited memory addressing range, combined with a need for ever more memory lead to a complex memory banking system. - Word length was 15 bits, ones-complement (mostly). - No floating point - everything done in integer - programmer responsible for avoiding overflows. - Single bit 'Up/Down' Analog to Digital conversion (kind of) throughout, with the curious side-effect that the faster the spacecraft was rotating, the slower the computer would run... On top of the limited hardware was built an impressive realtime system supporting cooperative multitasking, a virtual machine running interpreted commands, a powerful fault detection and restart system, and an innovative VERB NOUN user interface. This talk aims to describe the architecture, with particular focus on aspects which are unusual by modern standards. about this event: https://c3voc.de </description> <enclosure url="https://cdn.media.ccc.de/events/emf/2022/h264-hd/emf2022-105-eng-The_curious_design_of_the_Apollo_Guidance_Computer_hd.mp4" length="118489088" type="video/mp4"/> <pubDate>Sat, 04 Jun 2022 14:20:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/emf/2022/h264-hd/emf2022-105-eng-The_curious_design_of_the_Apollo_Guidance_Computer_hd.mp4?1704582680</guid> <dc:identifier>85f79a5d-e0e7-5155-a0c7-d0dc44ab28d2</dc:identifier> <dc:date>2022-06-04T14:20:00+02:00</dc:date> <itunes:author>Steve Baines</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>emf2022, 105, 2022</itunes:keywords> <itunes:summary>The Apollo Guidance Computer (AGC) was a critical element in the success of the Apollo Moon landing programme, and was one of the first digital computers to use the then new technology of integrated circuits.

The Digi-Gurdy project started as a 3D printed version of the keyboard part of the instrument in isolation, with some internal electronics, for my own personal use to learn a few tunes on. After posting on Thingiverse, a website for sharing 3D printed ideas, I had many requests from people asking me to build them one. This open-source project has developed through many variations which I would bring to the talk, resulting in an all laser-cut wooden full-size hurdy gurdy design with a realistic crank handle system and a detachable playable keybox for travelling.

This decade is arguably the 'last roll of the dice' when it comes to acting on climate. We've spent the last two years digging deep into financial and policy systems, working out how to shift money away from fossil fuels and towards things that might not be awful—and that markets might actually do at scale. Building on the experiences of developing the Open Banking Standard, the Open Data Institute and AMEE, we'll report on how we're progressing to try and deliver a *demonstrably* net-zero future—by unlocking real-world data-flows. Learn about what companies, countries, markets and governments are doing today: the good, the bad and the ugly. Learn what you can do, wherever you are, to be an Icebreaker and help all of us address our climate, environmental and biodiversity emergencies.

We've spent the last two years digging deep into financial and policy systems, working out how to shift money away from fossil fuels and towards things that might not be awful—and that markets might actually do at scale. Building on the experiences of developing the Open Banking Standard, the Open Data Institute and AMEE, we'll report on how we're progressing to try and deliver a *demonstrably* net-zero future—by unlocking real-world data-flows. Learn about what companies, countries, markets and governments are doing today: the good, the bad and the ugly. Learn what you can do, wherever you are, to be an Icebreaker and help all of us address our climate, environmental and biodiversity emergencies.

Unfortunately, they don't get to see the presentation before they talk about it! Powerpoint Karaoke will feature a selection of AI titled packs for attendees to present with only a moment to see what they’re about to talk about. The presentations will be interesting but we can't promise they'll be informative! With the rise of crypto-nonsense, washing machines bricked by ransomware and whatever the metaverse is never has there been a better time for people to take the stage and attempt to convince everyone that they know better than the AI overlord telling them what to talk about.

But it wasn't always quite that way... This talk will be a potted history of the safety of the railways in the UK and Ireland, starting from the early days when signalling was thought of as an inconvenience, and anything with wheels on it which sort-of went round went on the track. Eventually, the railway companies learned the benefits of adopting safer methods of working (sometimes requiring some encouragement from the law), leading to the introduction of some Victorian methods we still use today. Finally, we look at the more modern era with the railway losing its way with privatisation, and onto the current time, where computers and paperwork solve everything. Perhaps. Featuring: Swiss Cheese, Charles Babbage vs. Brunel, working too hard, forgetting where you put your trains, losing your religion, a dark and stormy night, drunken driving, a loose screw, shifting foundations, and more. No previous knowledge of the rail industry is required. The talk will cover some recent fatal accidents at a high level. about this event: https://c3voc.de </description> <enclosure url="https://cdn.media.ccc.de/events/emf/2022/h264-hd/emf2022-104-eng-A_Crash_Course_In_Railway_Safety_hd.mp4" length="166723584" type="video/mp4"/> <pubDate>Sat, 04 Jun 2022 16:40:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/emf/2022/h264-hd/emf2022-104-eng-A_Crash_Course_In_Railway_Safety_hd.mp4?1704584710</guid> <dc:identifier>4d26518e-30b1-54fd-8629-bff4b5a3a207</dc:identifier> <dc:date>2022-06-04T16:40:00+02:00</dc:date> <itunes:author>Anthony Williams</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>emf2022, 104, 2022</itunes:keywords> <itunes:summary>Travelling by rail in most of the world is one of the safest forms of transport you can take, and in the UK even minor collisions make the news.

Is there dark magic in tech? And what does that have to do with a teleporting duck in a classroom?! We often hold creating 'a magical experience' as a key goal for design - it's fun, engaging, sometimes even playful, and it makes complex things look simple. But technological magic has a dark side too, especially when trying to help people learn and feel confident about technology. By its nature, magic you experience is not under your control: it's a trick, and you're not supposed to be able to understand it; magic is inscrutable, and for many, that's disempowering. In designing the BBC micro:bit and surrounding tools, we've thought a lot about the balance between the positive and the negative sides of creating of a magical experience. This talk will reflect on our struggle to balance technical authenticity and honesty with the need to provide a high quality experience that excites and inspires students. It will explain how we attempt to present simple, understandable analogs of more complicated, magical technology in order to help students gain a sense confidence with the tech around them. However, it will also look at how we've resorted to using our own bits of (nearly) invisible magic to make this all work nicely in a classroom. Through this discussion we'll look in detail at the presentation of the micro:bit's IO, the way the micro:bit's USB interface works, the microphone privacy LED, the web-based compiler and the simple radio communication. Finally, I will look beyond micro:bit at how using this concept of balancing transparency and magic can help us build better, more trustworthy tech. about this event: https://c3voc.de </description> <enclosure url="https://cdn.media.ccc.de/events/emf/2022/h264-hd/emf2022-267-eng-Making_technology_deliberately_distinguishable_from_magic_designing_the_BBC_microbit_hd.mp4" length="133169152" type="video/mp4"/> <pubDate>Sun, 05 Jun 2022 12:20:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/emf/2022/h264-hd/emf2022-267-eng-Making_technology_deliberately_distinguishable_from_magic_designing_the_BBC_microbit_hd.mp4?1704589755</guid> <dc:identifier>f7312b4f-959a-5417-9fcc-3f376d3edb04</dc:identifier> <dc:date>2022-06-05T12:20:00+02:00</dc:date> <itunes:author>Jonny Austin</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>emf2022, 267, 2022</itunes:keywords> <itunes:summary>Should we really be trying to make our tech indistinguishable from magic?

Thus began a decade of film production that would have phenomenal overseas impact but be almost totally forgotten in Britain. Between 1940–1950, the British Council produced over 120 short documentary-style films about life in Britain covering sports, manufacturing, landscapes, art, architecture, public healthcare, the justice system, democratic process, public institutions like the National Trust and the BBC, and more besides. A far cry from the Ministry of Information's rigid style, this collection features some of the earliest works by winning cinematographers Geoffrey Unsworth (2001: A Space Odyssey, Cabaret, Superman), and Jack Cardiff (A Matter of Life and Death, Black Narcissus, The Red Shoes). Distributed to over 100 countries worldwide, the films are stunning, dated, funny, and bizarre by turn. They depict beautiful countrysides, optimistic cities, strong industry, forward-thinking social structures, and hardworking, happy people. They depict exactly the popular image of 1940s Britain that persists to this day... That may not be a coincidence.

In order to explain these theories and share my recurrent episodes of screaming WHYYYYYYYY at the universe, I've collected a number of memes and references over the years to convey concepts such as what is it to 'exist', why the scientific method is just as 'made up' as anything else, how we define 'truth' and lots of other tasty things to create a pervasive, disjointed feeling that you just can't seem to shake.

Transport for London provides an API ("TrackerNet") to get departure boards for all the stations -- but (ab)using that information to track the journeys of each individual train has proven much harder than expected. I'll explain how I built a system to squeeze useful insights out of an API not really designed to provide them -- including a fair few workarounds for TfL's capricious signalling systems, way more graph theory than I have any right doing, and why I now really hate the District Line. You'll be able to see how applying a carefully tuned pile of random maths lets me go from a chaotic jumble of data to a near-perfect model of the Tube map! I'll also cover the practicalities of running this system, explaining how I packaged it all up into a website people can actually use without getting banned by TfL for using their API too much or overloading the server I run it on.

The hardest part is devising open-ended interaction, spaces that invite people to reveal their authentic selves, and to connect with those around. But trends in technology have gone in the opposite direction. Whether it's for usability, profit, safety, profit or 'sparking joy', or profit (it's usually profit), 'User Experience Design' was the flavour of the 2010s.

This machine is unique in many respects: - It is the most powerful microscope, which can probe the distance one million times smaller than the size of the proton - It can reproduce conditions of the hot Early Universe with the temperature billion times higher than in the core of the sun, corresponding to a picosecond after the Big Bang This uniqueness gives the LHC opportunity to resolve the biggest puzzles of the Universe: - to find the origin of Matter-Antimatter asymmetry – the origin of planets and starts - to Shed a light on the origin of Dark Matter and Dark Energy, 95% of which the Universe is made of (stars and planets contribute only 5% to it !) - to give us the answer on what is the ultimate theory which drives this Universe – at micro and macro scales. In the presentation I will explain the exciting details of the Large Hadron Collider and how it helps to solve the most challenging problems of particle physics and cosmology – from micro to macro scales. https://docs.google.com/presentation/d/1YiUERbdFC7pUVuayv8Swxslz5TvL8X-yFvkLq_1cvNs/edit?usp=sharing about this event: https://c3voc.de </description> <enclosure url="https://cdn.media.ccc.de/events/emf/2022/h264-hd/emf2022-156-eng-The_Highest_Energy_Machine_on_the_Earth_to_Solve_the_Biggest_Puzzles_of_the_Universe_hd.mp4" length="108003328" type="video/mp4"/> <pubDate>Fri, 03 Jun 2022 15:20:00 +0200</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/emf/2022/h264-hd/emf2022-156-eng-The_Highest_Energy_Machine_on_the_Earth_to_Solve_the_Biggest_Puzzles_of_the_Universe_hd.mp4?1704577442</guid> <dc:identifier>5e083104-a683-5a21-bea7-6835162768a7</dc:identifier> <dc:date>2022-06-03T15:20:00+02:00</dc:date> <itunes:author>Alexander Belyaev</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>emf2022, 156, 2022</itunes:keywords> <itunes:summary>The largest and the highest energy scientific device - the Large Hadron Collider (LHC) is currently in operation at CERN.

Recovering files taken hostage by ransomware (37c3)</title> <link>https://media.ccc.de/v/37c3-11903-unlocked_recovering_files_taken_hostage_by_ransomware</link> <description>We present an analysis and recovery method for files encrypted by Black Basta, the "second most used ransomware in Germany". We analysed the behaviour of a ransomware encryptor and found that the malware uses their keystream wrongly, rendering the encryption vulnerable to a known-plaintext attack which allows for recovering affected files. We confirmed the finding by implementing tools for recovering encrypted files. We have made our tools for decrypting files without access to the actual key available to victims directly, through BSI, and to incident responders, as well as German and international law enforcement. Now, we are actively publishing these tools, along with the knowledge shared in our talk, empowering affected organizations to recover some of their files without succumbing to paying the criminals. We present an analysis of the Black Basta ransomware and tools for recovering encrypted files without access to the official decryptor or key. Black Basta is "the second most used ransomware in Germany", encrypting Windows computers and ESXi hosts running virtual machine workloads. Our decryptor-tool exploits a weakness in the cryptographic code in the Black Basta malware. This weakness allows to (partially) recover encrypted files without access to the decryptor and without needing the cryptographic keys used by the ransomware. We dive into the details of the cryptographic operations used by Black Basta and explain how the malware fails to use the cryptographic primitives properly. In particular, the Black Basta ransomware encrypts victim files using a stream cipher. Files smaller than 5000 bytes are fully encrypted. Larger files are only partially encrypted for efficiency reasons. We found that for larger files, the ransomware re-uses the same cryptographic keystream for encrypting different parts of the same file, thereby breaking the security of the used stream cipher. If the plaintext of any encrypted file part is known, the keystream can be recovered and used to decrypt (large parts of) the target file without the underlying cryptographic key. Affected organisations can check whether the variant of the Black Basta malware found in their network is susceptible to this attack by purposefully letting the ransomware encrypt a large file (512 MB) containing only zero bytes. If the encrypted parts of the file are identical when analysing the encrypted file (e.g. in a hex editor), recovery is likely possible using the tools presented here. Depending on the encrypted file, parts of the plaintext may be known. For instance, VM disk images are likely to contain stretches of zero bytes. As part of the tooling we have developed, we have implemented a heuristic to detect encrypted zero blocks in encrypted files. If found, (large parts of) the encrypted file can then be recovered. For other types of files, individual plaintext blocks may be recoverable via other means (e.g. using backups or specialised tools), also enabling data recovery.

(37c3)</title> <link>https://media.ccc.de/v/37c3-12240-chatkontrolle_-_es_ist_noch_nicht_vorbei</link> <description> In diesem Vortrag wollen wir auf die letzten knapp drei Jahre Kampf gegen die Chatkontrolle zurückblicken. Ein Kampf, der genauso droht zu einem Wiedergänger zu werden wie die Vorratsdatenspeicherung. Wir waren auf eine harte Auseinandersetzung um Überwachung und sichere Kommunikation vorbereitet. Als Patrick 2020 angefangen, hat uns vor dem, was da kommt, zu warnen, haben wir nicht erwartet, dass es sich zu einer Tragödie entwickeln würde, in der es nicht um Kinderschutz oder Überwachung geht. Sondern um eine Kommission, der jedes Mittel recht ist. Und Korruption und Lobbyskandal. Über die Chatkontrolle wurde in den letzten zwei Jahren viel geredet – die problematischen Inhalte des Gesetzes kommen den meisten von uns wahrscheinlich zu den Ohren heraus. Aber letztlich geht es um nicht weniger als einen historischen Kampf um Ende-zu-Ende-Verschlüsselung. Auf dem Tisch liegt das Thema aber schon deutlich länger. Wir wollen zurückblicken auf die Ursprünge und Kernpunkte des Gesetzesvorschlags. Und dann zusammen mit dem Publikum noch einmal die unüberschaubaren Wege gehen, die die Arbeit an diesem Gesetzesentwurf genommen hat. Aus der Perspektive von Deutschlands oberstem Datenschützer (Ulrich Kelber), dem Abgeordneten des Europäischen Parlamanets (Patrick Breyer) und der digitalen Zivilgesellschaft (khaleesi) erzählen wir die bisherige Geschichte der Chatkontrolle. Wenn ihr dachtet, ihr hättet alles zur Chatkontrolle gehört, bereitet euch auf eine absurde Tragödie vor, die ihr Ende noch nicht gefunden hat.

Ein Kampf, der genauso droht zu einem Wiedergänger zu werden wie die Vorratsdatenspeicherung. Wir waren auf eine harte Auseinandersetzung um Überwachung und sichere Kommunikation vorbereitet. Als Patrick 2020 angefangen, hat uns vor dem, was da kommt, zu warnen, haben wir nicht erwartet, dass es sich zu einer Tragödie entwickeln würde, in der es nicht um Kinderschutz oder Überwachung geht. Sondern um eine Kommission, der jedes Mittel recht ist. Und Korruption und Lobbyskandal. Über die Chatkontrolle wurde in den letzten zwei Jahren viel geredet – die problematischen Inhalte des Gesetzes kommen den meisten von uns wahrscheinlich zu den Ohren heraus. Aber letztlich geht es um nicht weniger als einen historischen Kampf um Ende-zu-Ende-Verschlüsselung. Auf dem Tisch liegt das Thema aber schon deutlich länger. Wir wollen zurückblicken auf die Ursprünge und Kernpunkte des Gesetzesvorschlags. Und dann zusammen mit dem Publikum noch einmal die unüberschaubaren Wege gehen, die die Arbeit an diesem Gesetzesentwurf genommen hat. Aus der Perspektive von Deutschlands oberstem Datenschützer (Ulrich Kelber), dem Abgeordneten des Europäischen Parlamanets (Patrick Breyer) und der digitalen Zivilgesellschaft (khaleesi) erzählen wir die bisherige Geschichte der Chatkontrolle. Wenn ihr dachtet, ihr hättet alles zur Chatkontrolle gehört, bereitet euch auf eine absurde Tragödie vor, die ihr Ende noch nicht gefunden hat. Trotz des Erfolgs im EU-Parlament haben wir noch lange nicht gewonnen. Denn alles hängt im und am Rat, dessen Position könnte im Trilog alles zunichte machen was wir hart erarbeitet haben. Und auch die Europawahlen stehen vor der Tür und damit kann sich nochmal alles ändern. Nicht fertige Gesetze werden in der EU in der nächste Legislaturperiode einfach weiterverhandelt.

Sie ist Deutschlands größter Industrieverbraucher an fossilen Ressourcen wie Öl und Gas. Wir stellen eine neue Studie „Blackbox Chemieindustrie“ des BUND zum Energie- und Ressourcenbedarf der Industrie vor. Die angeblich klimaneutralen Transformationspläne der Industrie werden kritisch hinterfragt und echte Lösungen werden aufgezeigt. Flammschutzmittel für Elektrogeräte, die Metalllegierung zum Löten und Plastik für fast alle Anwendungen im Alltag – all diese Materialen produziert die Chemische Industrie. Sie steht am Anfang der Wertschöpfungskette. Die Materialien, die sie herstellt definiert das Spektrum, mit dem Produktdesigner\*innen arbeiten können. Schockierend ist: Die Industrie verwendet nicht nur fossile Rohstoffe für viele ihrer Produkte, sondern ist auch größter Industrieverbraucher von Energie in Deutschland. Allein für die Produktion von Plastik für Verpackungen verwendet die Industrie in Deutschland mehr Primärenergie, als das Land Slowenien insgesamt. Viele Produkte der Industrie bergen Umwelt- und Gesundheitsgefahren und kein deutsches Chemieunternehmen hat eine Strategie ihre Schadstoffe zu reduzieren. Tatsächlich produzieren und exportieren die Unternehmen sogar weiterhin Schadstoffe, die in der EU längst verboten sind. Dass es so nicht weiter gehen kann erkennt auch die Industrie. Ihre angeblich klimaneutralen Transformationspfade sind technisch und wirtschaftlich nicht sinnvoll und gehen mit einem enormen Anstieg an nicht verfügbarer erneuerbarer Energie und Wasserstoff einher. Der Bedarf übersteigt was die Bundesregierung für ganz Deutschland vorsieht. Wir zeigen auf: Die Transformation der Chemieindustrie kann nicht nur innerhalb dieser Branche gedacht werden. Es darf jetzt nicht in Technologien investiert werden, die Scheinlösungen sind. Die Herausforderungen Klimakrise, Verschmutzung und Biodiversitätskrise müssen jetzt angegangen werden durch echte Defossilisierung, Ressourceneinsparung und Kreislaufwirtschaft und einer Umstellung auf sichere und nachhaltige Chemikalien. about this event: https://events.ccc.de/congress/2023/hub/event/blackbox_chemieindustrie/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11907-deu-eng-Blackbox_Chemieindustrie_hd.mp4" length="367001600" type="video/mp4"/> <pubDate>Sat, 30 Dec 2023 12:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11907-deu-eng-Blackbox_Chemieindustrie_hd.mp4?1703945764</guid> <dc:identifier>5e80f829-e2fe-4dd9-906c-7a18e9b7518a</dc:identifier> <dc:date>2023-12-30T12:00:00+01:00</dc:date> <itunes:author>Janna Kuhlmann, Janine Korduan</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 11907, 2023, Sustainability & Climate Justice</itunes:keywords> <itunes:subtitle>Die energieintensivste Industrie Deutschlands</itunes:subtitle> <itunes:summary>Am Anfang von jedem Chip, jedem Computer, jedem Plastik steht die Chemieindustrie.

However, one console has been left overlooked: the Nintendo DSi. It didn't see any serious hacks in its active lifetime, the ones that eventually appeared aren't completely satisfactory, and several components (such as its boot ROMs) were left untouched. In this presentation, we rectify the situation, explain how to extract the boot ROMs, and demonstrate new jailbreaks that can take over the console at an even deeper level. As a bonus, this work makes it possible to revive consoles with worn-out eMMC NAND chips. This presentation will start with an introduction to the hardware of the Nintendo DSi and the history of earlier hacking attempts. This is followed by an explanation on how to extract, analyze, and exploit the boot ROMs of the console, leading to a complete defeat of the security of the system. This presentation will not shy away from technical explanations involving software exploitation, fault injection, cryptography, and hardware design. We will however try to make it understandable and enjoyable to less technically-inclined audiences. about this event: https://events.ccc.de/congress/2023/hub/event/nintendo_hacking_2023_2008/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11736-eng-deu-fra-Nintendo_hacking_2023_2008_hd.mp4" length="274726912" type="video/mp4"/> <pubDate>Thu, 28 Dec 2023 14:45:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11736-eng-deu-fra-Nintendo_hacking_2023_2008_hd.mp4?1703944364</guid> <dc:identifier>bdeddf79-e7f0-46d3-b3ee-c427026c1523</dc:identifier> <dc:date>2023-12-28T14:45:00+01:00</dc:date> <itunes:author>PoroCYon</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 11736, 2023, Security</itunes:keywords> <itunes:subtitle>Finishing off the Nintendo DSi</itunes:subtitle> <itunes:summary>Over the years, many talks about console jailbreaks have been presented at CCC.

Das Ziel dieser Veranstaltung ist es, euch ein besseres Verständnis davon zu vermitteln, wie man mit einem reinen Text-Interface einen kompletten Computer steuern kann, damit ihr es später leichter habt, auf diesem Wissen aufzubauen. Ihr seid herzlich eingeladen, auf eurem eigenen Linux-Computer ein Terminal-Fenster zu öffnen und mitzumachen. about this event: https://events.ccc.de/congress/2023/hub/event/linux-kommandozeile-fr-newbies/ </itunes:summary> <itunes:duration>01:36:40</itunes:duration> </item> <item> <title>37C3: Feierlicher Abschluss (37c3)</title> <link>https://media.ccc.de/v/37c3-12339-37c3_feierlicher_abschluss</link> <description> about this event: https://events.ccc.de/congress/2023/hub/event/37c3_feierlicher_abschluss/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12339-deu-eng-37C3_Feierlicher_Abschluss_hd.mp4" length="355467264" type="video/mp4"/> <pubDate>Sat, 30 Dec 2023 18:20:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12339-deu-eng-37C3_Feierlicher_Abschluss_hd.mp4?1703962995</guid> <dc:identifier>1dbaf470-5dff-4cbb-a1ef-40d75c01c43f</dc:identifier> <dc:date>2023-12-30T18:20:00+01:00</dc:date> <itunes:author>Katharina Nocun, derPUPE, Mullana</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 12339, 2023, CCC</itunes:keywords> <itunes:summary> about this event: https://events.ccc.de/congress/2023/hub/event/37c3_feierlicher_abschluss/ </itunes:summary> <itunes:duration>00:26:14</itunes:duration> </item> <item> <title>Rückkanal bei der Podcasterei: (37c3)</title> <link>https://media.ccc.de/v/37c3-57998-rckkanal-bei-der-podcasterei-twitter-ist-tot-es-lebe-das-fediverse</link> <description>Offene Diskussion im Fishbowl-Format: <a href="https://sendegate.de/t/37c3-session-rueckkanal-bei-der-podcasterei-twitter-ist-tot-es-lebe-das-fediverse/16719">https://sendegate.de/t/37c3-session-rueckkanal-bei-der-podcasterei-twitter-ist-tot-es-lebe-das-fediverse/16719</a> about this event: https://events.ccc.de/congress/2023/hub/event/rckkanal-bei-der-podcasterei-twitter-ist-tot-es-lebe-das-fediverse/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-57998-deu-Rueckkanal_bei_der_Podcasterei_Twitter_ist_tot_Es_lebe_das_Fediverse_hd.mp4" length="896532480" type="video/mp4"/> <pubDate>Fri, 29 Dec 2023 21:45:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-57998-deu-Rueckkanal_bei_der_Podcasterei_Twitter_ist_tot_Es_lebe_das_Fediverse_hd.mp4?1703948719</guid> <dc:identifier>c0933e3f-431e-52f4-864d-da7f148715ea</dc:identifier> <dc:date>2023-12-29T21:45:00+01:00</dc:date> <itunes:author>Andi, Jinxx, et al.</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 57998, 2023, Sendezentrum</itunes:keywords> <itunes:subtitle>Twitter ist tot, Es lebe das Fediverse?!</itunes:subtitle> <itunes:summary>Offene Diskussion im Fishbowl-Format: <a href="https://sendegate.de/t/37c3-session-rueckkanal-bei-der-podcasterei-twitter-ist-tot-es-lebe-das-fediverse/16719">https://sendegate.de/t/37c3-session-rueckkanal-bei-der-podcasterei-twitter-ist-tot-es-lebe-das-fediverse/16719</a> about this event: https://events.ccc.de/congress/2023/hub/event/rckkanal-bei-der-podcasterei-twitter-ist-tot-es-lebe-das-fediverse/ </itunes:summary> <itunes:duration>01:22:05</itunes:duration> </item> <item> <title>Try Mental Health Care - zuhause (fireshonks)</title> <link>https://media.ccc.de/v/37c3-57786-try-mental-health-care-zuhause</link> <description>Wir sollten uns alle mehr Zeit für Mental Health Care nehmen, also mehr für unsere psychische Gesundheit tun.

Now a lot of new (in part digital) tech (AI, blockchain, big data, fusion, quantum computing, genetic engineering) is supposed to help the transition to a sustainable society. Although some of them can actually help with parts of the transition, they are usually discussed not as tools to assist the broader societal change (economic, legal, social, political changes) but as replacement for the broader societal change. In effect they act as "change placebos" resulting in "placebo change", meaning no change at all. Using concrete examples, this talk wants to 1) show in which ways technological fictions are misused as diversion from the necessary change or already existing other technologies, 2) present reasons and explanations for such misuse and 3) a simple method to spot tech(no)fixes.

To understand why the sound of Super Metroid or SMW was so ahead of its time, we will look at all the details of how this processor works and how it plays music. The SPC700 by Sony is an 8-bit architecture that was developed and used as the S-SMP sound coprocessor in the Super Nintendo Entertainment System (SNES). A big leap ahead in sound synthesis capabilities, apart from these few years of glory in the 1990s the architecture enjoyed no further uses and has faded into obscurity outside SNES circles. This talk not only takes a look at the SPC700 architecture, which is both a usual and unusual 8-bit ISA, but also the sound and music capabilities of the SNES S-DSP that it was designed to control. The talk is designed to be approachable by anyone with a basic understanding of how a microprocessor works; in particular, it covers the basics of digital audio necessary to understand the S-DSP's sound synthesis features like ADPCM sample playback or echo buffers. about this event: https://events.ccc.de/congress/2023/hub/event/the_ultimate_spc700_talk/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11748-eng-deu-fra-The_Ultimate_SPC700_Talk_hd.mp4" length="439353344" type="video/mp4"/> <pubDate>Sat, 30 Dec 2023 14:45:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11748-eng-deu-fra-The_Ultimate_SPC700_Talk_hd.mp4?1703956711</guid> <dc:identifier>a88b52c5-050a-4dbb-a5f6-27093f402eed</dc:identifier> <dc:date>2023-12-30T14:45:00+01:00</dc:date> <itunes:author>kleines Filmröllchen</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 11748, 2023, Hardware & Making</itunes:keywords> <itunes:subtitle>The hardware behind the music of Super Mario World, Chrono Trigger, Super Metroid, and more</itunes:subtitle> <itunes:summary>The Super Nintendo Entertainment System's sound coprocessor, the S-SMP, runs on the mostly-forgotten SPC700 architecture.

A big leap ahead in sound synthesis capabilities, apart from these few years of glory in the 1990s the architecture enjoyed no further uses and has faded into obscurity outside SNES circles. This talk not only takes a look at the SPC700 architecture, which is both a usual and unusual 8-bit ISA, but also the sound and music capabilities of the SNES S-DSP that it was designed to control. The talk is designed to be approachable by anyone with a basic understanding of how a microprocessor works; in particular, it covers the basics of digital audio necessary to understand the S-DSP's sound synthesis features like ADPCM sample playback or echo buffers. about this event: https://events.ccc.de/congress/2023/hub/event/the_ultimate_spc700_talk/ </itunes:summary> <itunes:duration>00:59:09</itunes:duration> </item> <item> <title>Anarchistische Transformationsstrategien (fireshonks)</title> <link>https://media.ccc.de/v/37c3-57869-anarchistische-transformationsstrategien</link> <description>Wie wird im Anarchismus Gesellschaftsveränderung gedacht?

With an adapter cartridge that spies on the memory bus! Let's talk about how to reconstruct the Game Boy's memory state, emulate its graphics unit and then encode the image into an MJPEG stream for anyone to use as a USB video class device. In realtime. On an rp2040 microcontroller. The original goal of the open source project "GB Interceptor" was to capture gameplay for one specific game: Tetris. In order to live stream a Tetris tournaments from the contestant's personal Game Boys, the idea was to create an adapter that goes between the Game Boy and the game module to analyze the communication on the memory bus and reconstruct the game state. It turns out that it is actually possible to reconstruct the entire memory state of almost any game and in fact create an rp2040-based adapter that acts as a USB video class device offering the on-screen game footage in realtime. Players can simply put this adapter into their Game Boy and use it like a webcam without additional drivers or knowledge. An essential aspect of this concept is that the Game Boy basically runs all of its code directly from the ROM module, which makes it possible to directly follow the program counter of its 8bit CPU regardless of how the code branches. An image can then be recreated by emulating the graphics unit (PPU). However, there are many edge cases like interrupts, data from registers that are not visible on the bus, the link cable, DMA operations, synchronization of CPU and PPU, game bugs and even bugs in the Game Boy hardware itself. In this talk I will show how all this is done just on an rp2040 with spare cycles to encode everything as a 60fps MJPEG stream. I will shine a light on the edge cases - those that were solved and those that might just be unsolvable with this approach. And I will take you on a sightseeing tour through the 8bit hell that drives our iconic handheld from 1989. about this event: https://events.ccc.de/congress/2023/hub/event/reconstructing_game_footage_from_a_game_boy_s_memory_bus/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11928-eng-deu-fra-Reconstructing_game_footage_from_a_Game_Boys_memory_bus_hd.mp4" length="606076928" type="video/mp4"/> <pubDate>Fri, 29 Dec 2023 20:30:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11928-eng-deu-fra-Reconstructing_game_footage_from_a_Game_Boys_memory_bus_hd.mp4?1703908279</guid> <dc:identifier>6e205c92-eeff-4339-9028-e5f7b7bb03ee</dc:identifier> <dc:date>2023-12-29T20:30:00+01:00</dc:date> <itunes:author>Sebastian Staacks</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 11928, 2023, Hardware & Making</itunes:keywords> <itunes:subtitle>The GB Interceptor</itunes:subtitle> <itunes:summary>How do you capture a video from an 1989's Game Boy without modding the original hardware?

But what is that actually, a gamma-ray burst? How do we detect it? And why was the BOAT so special? Gamma-ray bursts are the biggest explosions in our Universe since the Big Bang: In just a few seconds, they release as much energy as the Sun will radiate over its entire lifetime. Even though they occur in far-away galaxies, their emission dominates the high-energy astrophysical sky during their seconds-long duration. They come from the cataclysmic deaths of very massive stars or the mergers of two compact objects such as neutron stars and black holes. In both cases the energy is concentrated in an astrophysical jet moving at approximately the speed of light. In October 2022, a once-in-a-lifetime gamma-ray burst smashed records and was dubbed the ‘Brightest of All Time,’ or the BOAT. In fact, it was so bright that it oversaturated the most sensitive gamma-ray burst monitors, posing a challenge for data reconstruction and analysis. But why was it so bright? And how long do we have to wait until the next one? Using the BOAT as an example, we will give an introduction about the fascinating phenomena called gamma-ray bursts. From their accidental discovery during the Cold War to our still surprisingly limited understanding of their nature. The talk will revisit the state-of-the-art of theoretical modelling/interpretations (how are jets launched? what produces the gamma rays?), as well as current detector techniques (how do we catch a gamma-ray photon on Earth or in space?). Naturally, we will also discuss what we really learn from prominent, outstanding events such as the BOAT -- and the questions that still give scientists headaches. about this event: https://events.ccc.de/congress/2023/hub/event/about_gamma-ray_bursts_and_boats/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12032-eng-deu-About_Gamma-Ray_Bursts_And_Boats_hd.mp4" length="433061888" type="video/mp4"/> <pubDate>Fri, 29 Dec 2023 16:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12032-eng-deu-About_Gamma-Ray_Bursts_And_Boats_hd.mp4?1703891802</guid> <dc:identifier>18552f41-6ff7-4724-badd-701532dae724</dc:identifier> <dc:date>2023-12-29T16:00:00+01:00</dc:date> <itunes:author>Annika Rudolph, Sylvia Zhu</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 12032, 2023, Science</itunes:keywords> <itunes:subtitle>What We (Don't) Know About the Most Energetic Events in the Universe</itunes:subtitle> <itunes:summary>In October 2022 a gamma-ray burst dubbed the 'Brightest Of All Times' smashed records.

And how long do we have to wait until the next one? Using the BOAT as an example, we will give an introduction about the fascinating phenomena called gamma-ray bursts. From their accidental discovery during the Cold War to our still surprisingly limited understanding of their nature. The talk will revisit the state-of-the-art of theoretical modelling/interpretations (how are jets launched? what produces the gamma rays?), as well as current detector techniques (how do we catch a gamma-ray photon on Earth or in space?). Naturally, we will also discuss what we really learn from prominent, outstanding events such as the BOAT -- and the questions that still give scientists headaches. about this event: https://events.ccc.de/congress/2023/hub/event/about_gamma-ray_bursts_and_boats/ </itunes:summary> <itunes:duration>01:01:23</itunes:duration> </item> <item> <title>Oh no: KUNO - Gesperrte Girocards entsperren (37c3)</title> <link>https://media.ccc.de/v/37c3-11826-oh_no_kuno_-_gesperrte_girocards_entsperren</link> <description>Debitkarte/girocard geklaut? – Schnell sperren lassen … doch was, wenn die Sperrung nicht so wirksam ist, wie es scheint?

Their high accuracy and low false positive rates – probabilities – can sound dazzling. But translating the identical statistical information into frequency formats – body counts – shows they tend to backfire. The common (false positives) overwhelms the rare (true positives) – with serious possible consequences. Ignoring this fact is known as the base rate fallacy - a common cognitive bias. Due to pervasive cognitive biases such as this, as well as perverse structural incentives, society needs a regulatory framework governing programs that share this dangerous structure. This framework must work at the system rather than individual level. It should include better mechanisms for evidence-based policymaking that holds interventions to basic scientific evidentiary standards, and a right to deliberate ignorance where relevant. These solutions may help combat perverse incentives and cognitive biases, mitigating the damage from these dangerous programs. But we should expect ongoing sociopolitical struggle to articulate and address the problem of likely net damage from this type of program under common conditions. New technology seems to herald progress toward improving public safety in relation to old threats, from heinous crimes like child sexual abuse and terrorism, to illnesses like cancer and heart disease. Enter "Chat Control," a mass scanning program designed to flag potential child sexual abuse material in digital communications. While the goal of protecting children from exploitation is laudable, the statistical and social implications of such a mass screening program are scary. An empirical demonstration of Bayes’ rule in this context shows that, under relevant conditions of rarity, persistent inferential uncertainty, and substantial secondary screening harms, Chat Control and programs like it backfire, net degrading the very safety they’re intended to advance. Highlighting the inescapable accuracy-error dilemma in probability theory, we'll journey through the nuances of the base rate fallacy, highlighting how mass screening programs’ real-world efficacy is often not what it seems. When screenings involve entire populations, high "accuracy" translates into huge numbers of false positives. Additionally, proponents of such screenings have perverse incentives to inflate accuracy — and real-world validation to mitigate such inflation is often impossible. Dedicated attackers can also game the system, inflating false negatives. Meanwhile, secondary screening harms accrue to the very people we’re trying to protect. So, under certain common conditions, net harm can result from well-intentioned mass screenings. These problems extend well beyond this particular program. The structure and challenges faced by Chat Control parallel those faced by other programs that share the same mathematical structure across diverse domains, from healthcare screenings for numerous diseases, to educational screenings for plagiarism and LLM use, and digital platform screenings for misinformation. Numerous additional case studies are discussed in brief. But the pattern is the point. The laws of statistics don’t change. Maybe policy-level understanding of their implications, can. Solutions to the complex, system-level problem of mass screenings for low-prevalence problems (MaSLoPPs) must themselves work at the level of the system. This focus looks different from individual-level solutions often proposed, particularly in the health context in terms of risk communication and informed consent. Across contexts, we need evidence-based policy that holds interventions to basic scientific evidentiary standards. The burden of proof that new programs do more good than harm must rest on proponents. Independent reviewers should evaluate evidence to that standard. Transparency is a prerequisite of such independent review. In addition enhancing policymaker and public understanding of these statistical realities, and adopting widely accepted scientific evidentiary standards, society has to grapple with another set of perverse incentives: Politicians and policymakers may benefit from being seen as taking visible action on emotionally powerful issues — even if that action is likely to have bad consequences. This implicates the ancient tension between democratic participation and expertise that Plato satirized in “Gorgias.” Just as children might rather have their illnesses treated by pastry chefs than doctors, so too majorities in democratic publics might rather have their politicians “just do something” against horrible problems like child abuse, terror, and cancer — than not. Even if those efforts net harm people in exactly the feared contexts (e.g., degrading security and health). But if we care about outcomes, then critically evaluating interventions by explaining their statistical implications, and actually measuring outcomes of interest empirically, seems like a good start to improve evidence-based policymaking, and also presents one way to perhaps mitigate the problem of short-term perverse political incentives. Due to such perverse incentives and cognitive biases, we should expect political institutions to continue to struggle to formulate and implement a regulatory structure governing MaSLoPPs. One other facet of such a structure might stipulate deliberate ignorance as an opt-in/opt-out patient right. This way, medical information that is overwhelmingly likely to lead to needless anxiety and hassle at best — and unnecessary and harmful intervention at worst — such as incidental growth findings on imaging, doesn’t have to filter down to patients whom immediate healthcare providers may have financial incentives to overdiagnose.

Can an image model identify the happiest person or determine ethnicity from a random image? Most state-of-the-art text-to-image implementations rely on a number of limited datasets, models, and algorithms. These models, initially appearing as black boxes, reveal complex pipelines involving multiple linked models and algorithms upon closer examination. We engage artistic strategies like feedback, misuse, and hacking to crack the inner workings of image-generation models. This includes recursively confronting models with their output, deconstructing text-to-image pipelines, labelling images, and discovering unexpected correlations. During the talk, we will share our experiments on investigating Stable-Diffusion pipelines, manipulating aesthetic scoring in extensive public text-to-image datasets, revealing NSFW classification, and utilizing Contrastive Language-Image Pre-training (CLIP) to reveal biases and problematic correlations inherent in the daily use of these models. The talk will be conducted by sharing various experiments we've done under the umbrella of generative AI models. We will begin with a general idea of how we, as artists/programmers, perceive these models and our research on the workflow of these constructs. Then, we will further elaborate on our exploration of the Stable Diffusion pipeline and datasets. Throughout our investigation, we discovered that some essential parts are all based on the same few datasets, models, and algorithms. This causes us to think that if we investigate deeper into some specific mechanisms, we might be able to reflect on the bigger picture of some political discourses surrounding generative AI models. We deconstructed the models into three steps essential to understanding how they worked: dataset, embedding, and diffusions. Our examples are primarily based on Stable-Diffusion, but some concepts are interchangeable in other generative models. As datasets and machine-learning models grow in scale and complexity, understanding their nuances becomes challenging. Large datasets, like the one for training Stable Diffusion, are filtered using algorithms often employing machine learning. To "enhance" image generation, LAION's extensive dataset underwent filtering with an aesthetic prediction algorithm that uses machine learning to score the aesthetics of an image with a strong bias towards water-color and oil paintings. Besides the aesthetic scoring of images, images are also scored with a not safe-for-work classifier that outputs a probability of an image containing explicit content . This algorithm comes with its own discriminatory tendencies that we explore in the talk and furthermore asks how and by whom we want our datasets to be filtered and constructed. Many generative models are built upon Contrastive Language-Image Pre-training (CLIP) and its open-source version, Open-CLIP, which stochastically relates images and texts. These models connect images and text, digitize text, and calculate distances between words and images. However, they heavily rely on a large number of text-image pairs during training, potentially introducing biases into the database. We conducted experiments involving various "false labelling" scenarios and identified correlations. For instance, we used faces from ThisPersonDoesNotExist to determine "happiness" faces, explored ethnicities and occupations on different looks, and analyzed stock images of culturally diverse food. The results often align with human predictions, but does that mean anything? In the third part, we take a closer look at the image generation process, focusing on the Stable Diffusion pipeline. Generative AI models, like Stable Diffusion, have the ability not only to generate images from text descriptions but also to process existing images. Depending on the settings, they can reproduce input images with great accuracy. However, errors accumulate with each iteration when this AI reproduction is recursively used as input. We observed that images gradually transform into purple patterns or a limited set of mundane concepts depending on the parameters and settings. This raises questions about the models' tendencies to default to learned patterns. about this event: https://events.ccc.de/congress/2023/hub/event/self-cannibalizing_ai/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12125-eng-deu-Self-cannibalizing_AI_hd.mp4" length="621805568" type="video/mp4"/> <pubDate>Sat, 30 Dec 2023 16:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12125-eng-deu-Self-cannibalizing_AI_hd.mp4?1703958617</guid> <dc:identifier>097a5331-c705-4c1b-a77c-85397cfca426</dc:identifier> <dc:date>2023-12-30T16:00:00+01:00</dc:date> <itunes:author>Ting-Chun Liu, Leon-Etienne Kühr</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 12125, 2023, Art & Beauty</itunes:keywords> <itunes:subtitle>Artistic Strategies to expose generative text-to-image models </itunes:subtitle> <itunes:summary>What occurs when machines learn from one another and engage in self-cannibalism within the generative process?

Looking at each case study through a Tor lens will let us compare/contrast the censorship attempts from each country, discuss future ideas for how to make sure the bytes can keep flowing, and talk through the political impacts. about this event: https://events.ccc.de/congress/2023/hub/event/tor_censorship_attempts_in_russia_iran_turkmenistan/ </itunes:summary> <itunes:duration>01:02:41</itunes:duration> </item> <item> <title>Making homebrew for your very own Vector Super Computer (37c3)</title> <link>https://media.ccc.de/v/37c3-12297-making_homebrew_for_your_very_own_vector_super_computer</link> <description>The NEC Vector Engine (VE) isn't a GPU.

(37c3)</title> <link>https://media.ccc.de/v/37c3-11810-decentralized_energy_production_green_future_or_cybersecurity_nightmare</link> <description>In this talk we will have a look at some cybersecurity challenges raised by the trend of decentralizing our energy production. Our energy infrastructure is now changing from a centralized system based on big power plants to a more decentralized system based on renewable energy produced by smaller power plants (maybe yours). In Germany alone, [300.000 so called balcony power plants were in operation by August 2023](https://www.heise.de/hintergrund/Ueber-300-000-Balkonkraftwerke-in-Deutschland-in-Betrieb-Statistik-der-Woche-9285107.html). Most of these smaller power plants are / will be somehow connected to some cloud services. To show that security hasn't been the biggest priority, we will examine the cybersecurity controls of different solar inverters. To put it mildly: there is room for improvement. We will also discuss the need for better regulations and enforcement of cybersecurity for smaller connected power plants: altogether they probably produce more power than the bigger ones - and this trend is accelerating. Protecting our infrastructure shall have - today more than ever before - a high priority. Context: cybersecurity for future energy production systems ----------------------------------------------------------- Cybersecurity for smaller solar power plants is a critical challenge: strong separation between operational, safety relevant network and internet is not present. Moreover, manufacturers do not invest enough in security; reason being high competition in terms of time to market, price pressure and lack of security knowledge. These power plant systems need more or less an internet connection in order to fetch power & energy data from the plant with an app, perform firmware updates, and carry out maintenance remotely. The central device, which is connected to the internet, is the inverter. Many companies provide inverters for solar power plants and include cloud connectivity. An inverter converts the energy from the solar panels to grid compatible energy. Since it handles high currents & voltages, the physical consequences of cybersecurity risks are arguably higher than for standard smart home devices. Research results related to connected solar inverters (technical part) ---------------------------------------------------------------------- Out of curiosity, I tested different inverters from different manufacturers, including cloud connectivity. All devices have a license to be operated in Germany and are very popular. They are used in solar power plants of different sizes, from balcony size to bigger plants. In this section some research results will be presented, we will especially focus on one system. **Positive note: critical vulnerabilities have been patched by now.** Vulnerabilities --------------- * *Insecure Direct Object Reference* (IDOR) or similar vulnerabilities have been found, allowing an attacker with a simple account to execute commands on connected inverters remotely. This was an enabler for many further attacks. * An attacker could trigger a firmware update process on connected inverters. * The firmware update process was not properly secured: update images did not include a cryptographic signature. * Most of the devices did not use the TLS protocol for cloud communication or did not use it correctly. * Secure boot and secure debugging were not implemented. * On the server side, there were insufficient sanity checks. * Sensitive data (e.g. serial number) was easy to extract. Exploitation ------------ * Commands could be executed on any connected devices (e.g. switch ON, switch OFF, change parameters). * The power electronics and relays of devices could be manipulated remotely with a malicious firmware update. * By manipulating many devices synchronously the stability of the grid could be endangered. A proof of concept with a full (unlocked) exploit chain will be presented. Conclusion and Discussion ------------------------- Removing bureaucratic hurdles is an important step in order to democratize our energy production - and renewable energies are the future! On the other hand, if it comes at the cost of poorly-secured devices, this may be jeopardized. In Germany, we have the Kritis Verordnung (decree) to protect for example the electricity infrastructure. It states that every power [plant with more than 104 MW capacity is required to have specific protections](https://www.gesetze-im-internet.de/bsi-kritisv/anhang_1.html). Individually, the small solar power plants are not in this category. However, summing up all devices connected to one cloud, we probably reach these numbers by now - and if not, tomorrow. Current projections point in that direction. During this research, I realized how easy it is to take control of energy production devices and it scared me. The cloud connectivity and the related "remote control / remote maintenance" and "firmware update" processes are truly critical and attacks may scale. Even if vulnerabilities are patched by now, an attacker who finds a way into the cloud servers can control all connected inverters. On the other hand, it seems that there are no security related regulations regarding these systems as of today in the European Union. The [EU Cyber Resilience Act](https://digital-strategy.ec.europa.eu/en/library/cyber-resilience-act), which will apply to these devices is still in discussion and is likely to be effective soon. However, manufacturers will probably have a grace period of 36 months to comply: by then, many insecure devices will already be installed. Knowing how many bad guys are out there, the risk is there and growing rapidly. about this event: https://events.ccc.de/congress/2023/hub/event/decentralized_energy_production_green_future_or_cybersecurity_nightmare/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11810-eng-deu-fra-Decentralized_energy_production_green_future_or_cybersecurity_nightmare_hd.mp4" length="444596224" type="video/mp4"/> <pubDate>Thu, 28 Dec 2023 22:05:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11810-eng-deu-fra-Decentralized_energy_production_green_future_or_cybersecurity_nightmare_hd.mp4?1703933513</guid> <dc:identifier>0eced221-299d-4dba-ad51-6063978b2b41</dc:identifier> <dc:date>2023-12-28T22:05:00+01:00</dc:date> <itunes:author>Sebastien</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 11810, 2023, Security</itunes:keywords> <itunes:subtitle>The cybersecurity dark side of solar energy when clouds are involved</itunes:subtitle> <itunes:summary>In this talk we will have a look at some cybersecurity challenges raised by the trend of decentralizing our energy production.

All devices have a license to be operated in Germany and are very popular. They are used in solar power plants of different sizes, from balcony size to bigger plants. In this section some research results will be presented, we will especially focus on one system. **Positive note: critical vulnerabilities have been patched by now.** Vulnerabilities --------------- * *Insecure Direct Object Reference* (IDOR) or similar vulnerabilities have been found, allowing an attacker with a simple account to execute commands on connected inverters remotely. This was an enabler for many further attacks. * An attacker could trigger a firmware update process on connected inverters. * The firmware update process was not properly secured: update images did not include a cryptographic signature. * Most of the devices did not use the TLS protocol for cloud communication or did not use it correctly. * Secure boot and secure debugging were not implemented. * On the server side, there were insufficient sanity checks. * Sensitive data (e.g. serial number) was easy to extract. Exploitation ------------ * Commands could be executed on any connected devices (e.g. switch ON, switch OFF, change parameters). * The power electronics and relays of devices could be manipulated remotely with a malicious firmware update. * By manipulating many devices synchronously the stability of the grid could be endangered. A proof of concept with a full (unlocked) exploit chain will be presented. Conclusion and Discussion ------------------------- Removing bureaucratic hurdles is an important step in order to democratize our energy production - and renewable energies are the future! On the other hand, if it comes at the cost of poorly-secured devices, this may be jeopardized. In Germany, we have the Kritis Verordnung (decree) to protect for example the electricity infrastructure. It states that every power [plant with more than 104 MW capacity is required to have specific protections](https://www.gesetze-im-internet.de/bsi-kritisv/anhang_1.html). Individually, the small solar power plants are not in this category. However, summing up all devices connected to one cloud, we probably reach these numbers by now - and if not, tomorrow. Current projections point in that direction. During this research, I realized how easy it is to take control of energy production devices and it scared me. The cloud connectivity and the related "remote control / remote maintenance" and "firmware update" processes are truly critical and attacks may scale. Even if vulnerabilities are patched by now, an attacker who finds a way into the cloud servers can control all connected inverters. On the other hand, it seems that there are no security related regulations regarding these systems as of today in the European Union. The [EU Cyber Resilience Act](https://digital-strategy.ec.europa.eu/en/library/cyber-resilience-act), which will apply to these devices is still in discussion and is likely to be effective soon. However, manufacturers will probably have a grace period of 36 months to comply: by then, many insecure devices will already be installed. Knowing how many bad guys are out there, the risk is there and growing rapidly. about this event: https://events.ccc.de/congress/2023/hub/event/decentralized_energy_production_green_future_or_cybersecurity_nightmare/ </itunes:summary> <itunes:duration>00:39:30</itunes:duration> </item> <item> <title>Honey I federated the search engine - finding stuff online post-big tech (37c3-meta)</title> <link>https://media.ccc.de/v/37c3-lightningtalks-58060-honey-i-federated-the-search-engine-finding-stuff-online-post-big-tech</link> <description>It's getting harder and harder to find stuff on the Internet as search engines fill up with ads, SEO spam and AI generated hallucinations.

The system imitates exchange setups from different countries across the globe, allowing users to feel the genuine experience. Rotary-dial analogue phones were once a necessity, but now they lay dormant on shelves or tucked away in attics. This is largely due to the replacement of traditional landlines with fibre-optic modems, rendering analogue phones obsolete. In addition to their sentimental value, rotary dial phones provide several advantages, including reduced electrosmog emissions, protection against eavesdropping, repurposing outdated technology, and promoting a slower pace of life. The contribution explains how to build a private telephone exchange for eight people using rotary dial phones. The exchange is powered by a Raspberry Pi and custom analogue electronics. The following themes are covered: - The construction of a PBX which resembles telephone exchanges in various countries worldwide, giving users a realistic experience. - Handling of call initiation, routing, full duplex voice transmission and human-machine communication. - The software implementation on the Raspberry Pi running Linux. - A study of enhancing the open-source software with additional functionalities.

It does so by playing with the idiosyncrasies of audio representation/playback and mobilises them through the creation of an expanded musical situation. In the piece, three different containers of sound are presented: acoustic(Sound diffusion in the architecture), digital (computer based sound algorithms) and analogue (electromagnetic tape and analog processing). This containers, or buffers, are then being intertwined by the performer creating thus sonic textures that interplay with the resonances of the space.

It does so by playing with the idiosyncrasies of audio representation/playback and mobilises them through the creation of an expanded musical situation. In the piece, three different containers of sound are presented: acoustic(Sound diffusion in the architecture), digital (computer based sound algorithms) and analogue (electromagnetic tape and analog processing). This containers, or buffers, are then being intertwined by the performer creating thus sonic textures that interplay with the resonances of the space. The strategy for the sound performance is to articulate a metaphor of a circular-buffer, a data structure used in Computer Science, to the idea brought upon in Derrida’s interview with Ornette Coleman, in which Improvisation practice in music is understood as a reading in which the borders between reading and writing are obfuscated.

That was 40 years ago, creating art and beauty is one thing, but how do you maintain or develop it as a gallery, archive or museum? You know all about CI/CD and deploying to "the cloud"? Well, let me show you how to deploy to a museum or art space. Important note: this talk is not about NFTs. The preservation and presentation of software/computer-based art in museums presents unique challenges in the contemporary landscape. One prominent issue is the ephemeral nature of digital media, which includes websites, games, software and virtual reality art. Unlike traditional art forms, these works often rely on rapidly evolving technologies, making them vulnerable to obsolescence. Museums are faced with the task of preserving and restoring media art in a way that not only preserves the original intent of the artist, but also ensures accessibility for future audiences. Another significant challenge is the dynamic and interactive nature of many media artworks. Unlike static paintings or sculptures, digital artworks often require specific hardware, software or immersive environments to be experienced. Museums need to invest in both the technological infrastructure and the expertise to recreate these conditions and provide visitors with an authentic encounter with the artwork. In this talk we want to look at some solutions from the perspective of software developers who are motivated not only to preserve and present digital media art, but also to develop it with contemporary software development strategies. about this event: https://events.ccc.de/congress/2023/hub/event/devops_but_for_artworks_in_museums/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11931-eng-deu-DevOps_but_for_artworks_in_museums_hd.mp4" length="702545920" type="video/mp4"/> <pubDate>Fri, 29 Dec 2023 19:15:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11931-eng-deu-DevOps_but_for_artworks_in_museums_hd.mp4?1703946867</guid> <dc:identifier>293112df-d0f3-4502-8971-f2f9ed6401d3</dc:identifier> <dc:date>2023-12-29T19:15:00+01:00</dc:date> <itunes:author>obelix</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 11931, 2023, Art & Beauty</itunes:keywords> <itunes:subtitle>A look into pipelines ending in museums and not in the cloud</itunes:subtitle> <itunes:summary>In the original Hacker Ethics, Steven Levy stated that "you can create art and beauty on a computer".

It can be analyzed to detect fake base stations used in cellular attacks. For that, we reverse-engineered a proprietary communication channel between the phone’s OS and modem. Connecting to cellular networks around the world is a highly complex task. iPhones contain a baseband chip (also referred to as a modem) for that purpose. It communicates via a high-level interface with the smartphone’s application processor running iOS. So far, Apple hasn’t been able to build such basebands in-house. Instead, starting from the iPhone 12, they exclusively rely on Qualcomm basebands. Qualcomm’s basebands use a proprietary protocol for external communication, the Qualcomm MSM Interface. We reverse-engineered its iOS implementation and built a framework to extract the protocol’s packet structures from iOS firmware. Our iOS Wireshark dissector uses these packet structures and enables us to monitor the flow of packets between the baseband and iOS. This allows us to gain new insights into the iPhone’s wireless communication infrastructure, including its satellite connectivity. Our tooling also provides a novel way to directly interact with the baseband chip in jailbroken iPhones, bypassing iOS and unlocking hidden capabilities of the baseband. Fake or Rouge base stations can be set up by individuals using readily available software-defined radios. Adversaries can utilize them to capture IMSIs of nearby smartphones, track their location, or exploit vulnerable basebands. iPhone users usually don’t notice such attacks, and there are (almost) no protection mechanisms implemented in iOS. During our research, we discovered Apple’s internal cell location database, which is intended for determining approximate positions. Our CellGuard iOS app combines this database with the QMI analysis framework to monitor various parameters of connected cells, verify their authenticity, and alert users in case there’s suspicious activity. The app even works on non-jailbroken iPhones. We evaluated the app in a lab environment with SDRs and real-world tests since February 2023 and are steadily improving it for a release next year. about this event: https://events.ccc.de/congress/2023/hub/event/what_your_phone_won_t_tell_you/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11868-eng-deu-What_your_phone_wont_tell_you_hd.mp4" length="270532608" type="video/mp4"/> <pubDate>Fri, 29 Dec 2023 23:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11868-eng-deu-What_your_phone_wont_tell_you_hd.mp4?1703945032</guid> <dc:identifier>a3591274-c5c9-4d97-8404-d38abcb8d29a</dc:identifier> <dc:date>2023-12-29T23:00:00+01:00</dc:date> <itunes:author>Lukas Arnold</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 11868, 2023, Security</itunes:keywords> <itunes:subtitle>Uncovering fake base stations on iOS devices</itunes:subtitle> <itunes:summary>Your phone’s internal communication contains precious data.

(37c3)</title> <link>https://media.ccc.de/v/37c3-12298-should_e-voting_experience_of_estonia_be_copied</link> <description>Although electronic voting has been used 13 times in various elections in Estonia since 2005, the legal, procedural and technical problems are far from solved, but have rather backfired in political situation getting more complicated. Electronic voting is hard to observe because one can't directly see into computers. In case of Estonia, the cryptographic measures to verify the processes are only partially implemented, but as voters have to download a voting application that implements a protocol with a public specification, observers/voters can obtain a special insight into processes by implementing their own tools to cast and verify the votes. Engaging in that kind of participative observation with special tools in 2023 parliamentary elections in Estonia it appeared that the official voting software implemented the process that was not following the specification up to the point of diverging from requirements set in laws and subordinate regulative acts. In addition to couple of vote containers that were processed ignoring the requirements, in the end it appeared that arguably all 312 181 electronic votes cast with official voting application had invalid digital signatures and failed to specify electoral district in vote text. In paper ballot elections these kinds of ballots would have been declared invalid without hesitation, but electoral complaints filed about such electronic votes were dismissed without explanation of why ballots clearly not conforming to legal requirements were counted. This has resulted in a parliament where 22 of 101 representatives have arguably gained their mandate based on invalid ballots, but moreover this indicates that after about 20 years of electronic voting in Estonia, in order to run the elections huge amounts of legal and technical make-believe is needed. If manageable in small scale pilots and elections with low importance, this is hardly a case with 51% of the voters in parliamentary elections casting their votes online -- during times of political polarisation raising to unprecedented heights. about this event: https://events.ccc.de/congress/2023/hub/event/should_e-voting_experience_of_estonia_be_copied/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12298-eng-deu-fra-Should_e-voting_experience_of_Estonia_be_copied_hd.mp4" length="297795584" type="video/mp4"/> <pubDate>Sat, 30 Dec 2023 12:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12298-eng-deu-fra-Should_e-voting_experience_of_Estonia_be_copied_hd.mp4?1703945988</guid> <dc:identifier>65206c56-8766-4809-8d3b-9eb8028a63fe</dc:identifier> <dc:date>2023-12-30T12:00:00+01:00</dc:date> <itunes:author>Märt Põder</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 12298, 2023, Ethics, Politics & Society</itunes:keywords> <itunes:subtitle>Observer report of 2023 parliamentary elections</itunes:subtitle> <itunes:summary>Although electronic voting has been used 13 times in various elections in Estonia since 2005, the legal, procedural and technical problems are far from solved, but have rather backfired in political situation getting more complicated.

I outline the process of emulating an iPod Touch 2G, discussing the technical challenges and reverse engineering methodologies applied. The talk starts with an overview of the project's goals and then outlines the reverse engineering process, utilizing tools like Ghidra for disassembling the Apple bootloader, XNU kernel, and other binaries. Then, I describe QEMU, a popular framework for emulation, and show how essential iPod Touch peripherals such as the touchscreen, storage, and display have been implemented. Finally, this talk touches upon the implications of open-sourcing this project, its contribution to the emulation and reverse engineering landscape, and its potential for future efforts to emulate newer Apple devices. During the past decades, Apple has created iconic devices that have found a place in the hands and hearts of millions of people around the world. As many of these devices have become obsolete, the importance of preserving their digital essence has grown. The emulation of legacy devices with software allows enthusiasts and researchers to explore and interact with them long after the original hardware has ceased to be available. Emulation, therefore, allows the digital preservation of obsolete hardware, ensuring these devices are accessible to future generations. This talk describes a multi-year project named QEMU-iOS that lays the groundwork for emulating legacy Apple devices. In particular, we have focussed on emulating the iPod Touch 2G using QEMU, an open-source framework for hardware emulation. Yet, even emulating an old device with a few peripherals compared to contemporary devices is challenging since the specifications and inner workings of many peripherals are proprietary and completely undocumented. The talk first describes the overall project motivation, goals, and vision. Then, I will discuss the reverse engineering process where multiple undocumented peripherals of the iPod Touch have been analyzed to understand and replicate their specifications in software. A key talking point will be the working of essential peripherals, including the cryptographic engines, the LCD, the Flash memory controller, various hardware communication protocols, the touchscreen driver, and other peripherals. The talk will also detail the booting procedure of the iPod Touch, elaborating on the emulation of the iBoot bootloader, the XNU kernel, and the Springboard application in iOS. Getting the boot chain up and running required extensive debugging efforts using powerful reverse engineering tools such as Ghidra to disassemble and analyze all essential binaries in the boot procedure. After outlining the reverse engineering process, I will present the implementation of QEMU-iOS, which entails a functional emulator that boots the iOS operating system, renders the display, and responds to touches on the screen. The final part of this talk will touch upon the implications of open-sourcing this project, its contribution to the broader emulation and reverse engineering landscape, and the potential it holds for future efforts in emulating other legacy Apple devices, as well as the viability of emulating newer devices with advanced peripherals such as the Neural Engine. I will also discuss existing approaches, highlight where QEMU-iOS differs, and summarize the lessons learned while emulating these devices. This talk is designed for a wide range of people, whether you are new to reverse engineering and emulation or have experience in these fields. The goal is to explain the technical challenges faced during this project in a way that's easy for beginners to understand while also providing more in-depth insights I discovered while working on QEMU-iOS. Through this talk, the aim is not only to share the technical knowledge gained from this project but also to explore the merits of emulation and reverse engineering to keep old devices alive. about this event: https://events.ccc.de/congress/2023/hub/event/breathing_life_into_legacy_an_open-source_emulator_of_legacy_apple_devices/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11871-eng-deu-Breathing_Life_into_Legacy_An_Open-Source_Emulator_of_Legacy_Apple_Devices_hd.mp4" length="277872640" type="video/mp4"/> <pubDate>Fri, 29 Dec 2023 23:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11871-eng-deu-Breathing_Life_into_Legacy_An_Open-Source_Emulator_of_Legacy_Apple_Devices_hd.mp4?1703949809</guid> <dc:identifier>53a49d09-cb27-4e10-be69-24cc978c702a</dc:identifier> <dc:date>2023-12-29T23:00:00+01:00</dc:date> <itunes:author>Martijn de Vos</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 11871, 2023, Hardware & Making</itunes:keywords> <itunes:subtitle>A Dive into Reverse Engineering and Understanding the iPod Touch</itunes:subtitle> <itunes:summary>This talk presents QEMU-iOS, an open-source emulator of legacy Apple devices.

The myo armband was once a really strange way to control a computer, and then became a way to do fine-grained myomuscular electrical detection research. This is a talk about how to hook a myo to a Raspberry Pi 3B+ in 2023, and from there how to have the armband communicate over serial to other devices. We choose to use it to control a Programmable Air system for pneumatic control of muscular robots. Let's talk ten year old tech! The Myo armband from Thalmic Labs was once a really strange way to control a computer, and then became a pretty good way to do fine-grained myomuscular electrical detection research for prosthetics. These processes usually have a high cost or involve less-portable computing systems. In order to make a robotic effect that can be deployed apparently independently, it's more interesting to have a low-cost, encapsulated system. In this talk we'll walk through what it takes in 2023 to have a Thalmic Myo armband talk to a Raspberry Pi 3B+ using Python. We'll provide a demonstration of a pneumatic robot based on the Programmable Air system controlled over serial using the armband. The goal of this project is to have access to strong mechanical advantage without the compromises of servos or stepper motors, and with some of the organic feel possible with air or water systems. about this event: https://events.ccc.de/congress/2023/hub/event/encapsulated-electromyography-with-myo-and-raspi/ </description> <enclosure url="https://cdn.media.ccc.de/events/fireshonks/h264-hd/37c3-57905-eng-Encapsulated_Electromyography_with_Myo_and_Raspi_hd.mp4" length="293601280" type="video/mp4"/> <pubDate>Fri, 29 Dec 2023 22:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/events/fireshonks/h264-hd/37c3-57905-eng-Encapsulated_Electromyography_with_Myo_and_Raspi_hd.mp4?1703951159</guid> <dc:identifier>9dcaa41b-875e-5a2b-8c5f-ce47c0507ce2</dc:identifier> <dc:date>2023-12-29T22:00:00+01:00</dc:date> <itunes:author>Alex Leitch, Celia Chen</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 57905, 2023</itunes:keywords> <itunes:summary>Let's talk ten year old tech!

Schwule Onlineplattformen entstanden, um der Unterdrückung von homosexuellem Verhalten zu entgehen. Zynischerweise sorgen sie heute für eine unterschwellige, fesselnde Regulation homosexueller Menschen. Der Vortrag arbeitet sich zwar vor allem an MSM-Personen (Männer, die Sex mit Männern haben) ab, richtet sich aber ausdrücklich an Hacker:innen jeglicher Sexualität. Der Vortrag zeichnet erstens eine Kulturgeschichte der schwulen Subkultur und erklärt, warum Darkrooms und ähnliche Orte, an denen schwuler Sex in der semi-Öffentlichkeit vollzogen wird, konstitutiv für die schwule Szene waren. Zweitens werden die Effekte der Digitalisierung dieser Orte hin zu Plattformen wie früher GayChat oder heute Grindr aufgezeigt. Drittens wird gezeigt, warum homosexuelle Cruising-Apps wie Grindr kultur- und softwaretechnisch grundlegend anders aufgebaut sind als heterosexuelle Dating-Apps wie Tinder. Mit dem Vortrag möchte ich einen Anstoß geben, Dualismen wie Homo- und Heterosexualität, Cruising und Dating, Promiskuität und Monogamie zu hacken. Ich möchte zeigen, dass Interaktivität auf *Datingplattformen* häufig eine Illusion ist, und versuchen, gemeinsam mit dem Publikum Wege zu finden, den „interpassiven”-Konsumstatus im Onlinedating aufzubrechen. about this event: https://events.ccc.de/congress/2023/hub/event/vom_darkroom_in_die_blackbox/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12238-deu-eng-fra-Vom_Darkroom_in_die_Blackbox_hd.mp4" length="213909504" type="video/mp4"/> <pubDate>Sat, 30 Dec 2023 16:40:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12238-deu-eng-fra-Vom_Darkroom_in_die_Blackbox_hd.mp4?1703965375</guid> <dc:identifier>7b1188cf-948c-490c-b206-9ec6a22c45e9</dc:identifier> <dc:date>2023-12-30T16:40:00+01:00</dc:date> <itunes:author>LustigerLeo</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 12238, 2023, Ethics, Politics & Society</itunes:keywords> <itunes:subtitle>Effekte der Digitalisierung auf (schwules) Dating</itunes:subtitle> <itunes:summary>Entgegen der Auffassung, die schwule Subkultur hätte durch die digitale Vernetzung einen Aufschwung erhalten und sei in ihrem Aktivismus gestärkt worden, möchte ich eine gegenwärtige Krise der Subkultur markieren und ihren Entstehungskontext durch Onlinedating skizzieren.

Keine Sorge, je nach zu validierendem Input verwirrt es deinen Computer auch! Dieser Talk befasst sich mit regulären Ausdrücken: Wir steigen ein mit einem kurzen Ausflug in die theoretische Informatik und endliche Automaten, befassen uns allgemein mit regulären Ausdrücken und warum diese nützlich sind, bis wir herausfinden, was es mit bösen regulären Ausdrücken auf sich hat - und wie diese mit dem entsprechenden Payload für Denial of Service-Angriffe genutzt werden können.

Keine Sorge, je nach zu validierendem Input verwirrt es deinen Computer auch! Dieser Talk befasst sich mit regulären Ausdrücken: Wir steigen ein mit einem kurzen Ausflug in die theoretische Informatik und endliche Automaten, befassen uns allgemein mit regulären Ausdrücken und warum diese nützlich sind, bis wir herausfinden, was es mit bösen regulären Ausdrücken auf sich hat - und wie diese mit dem entsprechenden Payload für Denial of Service-Angriffe genutzt werden können.

Liebe Fördermitglieder des Institutes für Karaokeforschung, in den letzten Tagen haben wir uns intensiv mit den Karaoke-Gewohnheiten der örtlichen Bevölkerung des 37C3 im CCH befassen können. Unsere motivierten Proband\*innen im Alter zwischen 17 und 85 Jahren haben uns in dieser repräsentativen Studie direkte Einblicke in ihren Alltag gegeben. Allein dafür sind wir unendlich dankbar, Sie haben der Karaokeforschung einen großen Dienst erwiesen! Nun möchten wir Euch und Ihnen in einer Zwischenpräsentation Insights aus unserem aktuellen Kooperationsprojekt mit dem 37C3 präsentieren – und damit auch die dritte Phase der international angelegten Forschungsarbeit einläuten. Im Namen des gesamten Vorstandes möchte ich mich bei Ihnen recht herzlich für die Unterstützung auch im nächsten Jahr bedanken. Gleichzeitig die Bitte, Ihre Bankverbindung zu überprüfen, um die Arbeit unserer Buchhaltung zu vereinfachen.

This has made a lot of people very angry and been widely regarded as a bad move. But did you know Neptune was discovered as the 12th planet? Or that, 80 years before Star Trek, astronomers seriously suspected a planet called Vulcan near the Sun? This talk will take you through centuries of struggling with the question: Do you even planet?! In antiquity, scientists counted the 7 classical planets: the Moon, Mercury, Venus, the Sun, Mars, Jupiter and Saturn – but their model of the universe was wrong. Two thousand years later, a new model was introduced. It was less wrong, and it brought the number of planets down to 6: Mercury, Venus, Earth, Mars, Jupiter, Saturn. Since then, it's been a roller coaster ride of planet discoveries and dismissals. In this talk, we stagger through the smoke and mirrors of scientific history. We meet old friends like Uranus and Neptune, forgotten lovers like Ceres, Psyche and Eros, fallen celebrities like Pluto, regicidal interlopers like Eris and Makemake as well as mysterious strangers like Vulcan, Planet X and Planet Nine. Find out how science has been tricked by its own vanity, been hampered by too little (or too much!) imagination, and how human drama can make a soap opera out of a question as simple as: How Many Planets in Our Solar System? about this event: https://events.ccc.de/congress/2023/hub/event/how_many_planets_in_our_solar_system_glad_you_asked/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11734-eng-deu-spa-How_Many_Planets_in_Our_Solar_System_Glad_You_Asked_hd.mp4" length="580911104" type="video/mp4"/> <pubDate>Fri, 29 Dec 2023 17:15:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11734-eng-deu-spa-How_Many_Planets_in_Our_Solar_System_Glad_You_Asked_hd.mp4?1703884979</guid> <dc:identifier>83c74623-452b-45f9-85ba-6e91b1caceff</dc:identifier> <dc:date>2023-12-29T17:15:00+01:00</dc:date> <itunes:author>Michael Büker</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 11734, 2023, Science</itunes:keywords> <itunes:subtitle>How Astronomy Knew 6 Planets, Then Found 20 More, Then Went Back To 8 (For Now)</itunes:subtitle> <itunes:summary>The Solar System has had 8 planets ever since Pluto was excluded in 2006.

Dafür suchen wir Mitstreiter*innen! ### Mitmachen Das Projekt wird gerade im Rahmen des *Take-Off-Accelerator*-Programms der Hochschule für Technik und Wirtschaft des Saarlandes gefördert. Wenn Du mitgestalten möchtest, freue ich mich, von Dir zu hören: * Bis Tag 4 bin ich auf dem 37c3 anzutreffen. Ruf mich an unter **DECT [5671](tel:5671)**! * Du erreichst mich auch per E-Mail an [link@marvinreuter.de](mailto:link@marvinreuter.de) (möglicherweise werde ich erst nach dem Congress antworten). about this event: https://pretalx.c3voc.de/37c3-lightningtalks/talk/HAS887/ </itunes:summary> <itunes:duration>00:04:20</itunes:duration> </item> <item> <title>Der Weisheit (37c3)</title> <link>https://media.ccc.de/v/37c3-57925-der-weisheit-eine-stunde-lebenskunde-10-staffelfinale</link> <description>Der Weisheit hat ein ganzes Jahr 10.

(37c3)</title> <link>https://media.ccc.de/v/37c3-11844-what_is_this_a_machine_learning_model_for_ants</link> <description>This talk will give a brief introduction of deep learning models and the energy they consume for training and inference. We then discuss what methods currently exist for handling their complexity, and how neural network parameter counts could grow by orders of magnitude, despite the end of Moore's law. Declared dead numerous times, the hype around deep learning is bigger than ever. With Large Language Models and Diffusion Models becoming a commodity, we ask the question of how bad their energy consumption *really* is, what we can do about it, and how it is possible to run cutting-edge language models on off-the-shelf GPUs. We will look at the various ways that people have come up with to rein in the hunger for resources of deep learning models, and why we still struggle to keep up with the demands of modern neural network model architectures. From low-bitwidth integer representation, through pruning of redundant connections and using a large network to teach a small one, all the way to quickly adapting existing models using low-rank adaptation. This talk aims to give the audience an estimation of the amount of energy modern machine learning models consume to allow for more informed decisions around their usage and regulations. In the second part, we discuss the most common techniques used for running modern architectures on commodity hardware, outside of data centers. Hopefully, deeper insights into these methods will help improve experimentation with and access to deep learning models. about this event: https://events.ccc.de/congress/2023/hub/event/what_is_this_a_machine_learning_model_for_ants/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11844-eng-deu-What_is_this_A_machine_learning_model_for_ants_hd.mp4" length="318767104" type="video/mp4"/> <pubDate>Fri, 29 Dec 2023 13:50:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11844-eng-deu-What_is_this_A_machine_learning_model_for_ants_hd.mp4?1703879775</guid> <dc:identifier>97bdc540-c53a-4ec3-949d-39e4d947db18</dc:identifier> <dc:date>2023-12-29T13:50:00+01:00</dc:date> <itunes:author>etrommer</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 11844, 2023, Sustainability & Climate Justice</itunes:keywords> <itunes:subtitle>How to shrink deep learning models, and why you would want to.</itunes:subtitle> <itunes:summary>This talk will give a brief introduction of deep learning models and the energy they consume for training and inference.

Doch wo stehen wir eigentlich gerade wirklich, was können diese Systeme bereits jetzt für uns tun, und was bringt uns die Zukunft? Es ist höchste Zeit für einen unverfälschten „Reality Check“ und einen authentischen Blick in den Alltag von Menschen mit Behinderung. Es wird immer wieder behauptet, die Einführung generativer KI-Systeme wie ChatGPT und Midjourney habe eine neue Ära der Möglichkeiten eröffnet, insbesondere im Bereich der digitalen Barrierefreiheit. Diese Technologien und Unternehmen versprechen, den Alltag von Menschen mit Behinderungen durch innovative Lösungen zu erleichtern. Beispielsweise ermöglichen neue, multi-modale Large Language Models die Generierung von Alternativtexten, die visuelle Inhalte für sehbehinderte Nutzer\*innen zugänglicher machen könnten. Auch die Erstellung von Texten in Leichter Sprache kann durch diese Modelle vereinfacht werden, wodurch Informationen für Menschen mit Lernbehinderungen oder Nicht-Muttersprachler\*innen leichter verständlich werden können. Doch die Integration von KI in unseren Alltag als behinderte Menschen bringt nicht nur Vorteile. Trotz der neuen Fähigkeiten von KI-Systemen kommen einige neue Herausforderungen hinzu. Dazu gehören unter anderem reproduzierter Ableismus, neue für uns unsichtbare Barrieren und der zunehmende gesellschaftliche Unwille, Barrierefreiheit und somit echte Inklusion zu schaffen, wenn Hilfsmittel immer besser werden.

Wir haben dieses Konzept in die echte Welt übertragen und als Open Source Web-App für Karlsruhe umgesetzt. In diesem Lightning Talk tauchen wir in die aufregende Welt von Scotland Yard ein und zeigen, wie wir dieses fesselnde Spiel in die Realität übertragen haben. Inspiriert von den spannenden Jagden nach dem flüchtigen Mr X auf dem Londoner Stadtplan, haben wir eine Open-Source-Web-App entwickelt, die es den Spielern ermöglicht, sich in den Straßenbahnen von Karlsruhe zu koordinieren, um ihren eigenen "Mr X" zu finden.

Wir haben dieses Konzept in die echte Welt übertragen und als Open Source Web-App für Karlsruhe umgesetzt. In diesem Lightning Talk tauchen wir in die aufregende Welt von Scotland Yard ein und zeigen, wie wir dieses fesselnde Spiel in die Realität übertragen haben. Inspiriert von den spannenden Jagden nach dem flüchtigen Mr X auf dem Londoner Stadtplan, haben wir eine Open-Source-Web-App entwickelt, die es den Spielern ermöglicht, sich in den Straßenbahnen von Karlsruhe zu koordinieren, um ihren eigenen "Mr X" zu finden. Wir erkunden die Herausforderungen und den Reiz, ein Brettspiel in die reale Welt zu übertragen.

Since then, nearly no information has come out publicly about any vulnerabilities or even the algorithms themselves, owing in large part to software players requiring the use of Intel SGX secure enclave technology, which promises integrity and confidentiality of AACSv2 code and data through local and remote attestation mechanisms. Join us as we explore the broken history of AACS, describe practical side-channel attacks against SGX, and present the first look into the inner workings of AACSv2 DRM, culminating in a demonstration of the first full compromise of AACSv2 and unofficial playback of a UHD-BD disc. The Advanced Access Content System (AACS) is a DRM scheme used to safeguard audio and visual content, particularly in high-definition formats like HD-DVD and Blu-ray. First introduced in 2005 following the failure of the Content Scramble System (CSS) used in DVDs, AACS was designed to be not only secure against regular piracy, but included multiple features intended to restrict the impact of a potential leak of cryptographic material such as revocation lists and traitor-tracing. The concepts and algorithms of AACS were described in a publicly-released whitepaper, relying on strong cryptography and secrecy of keys to maintain security. Unsurprisingly, less than a year after publication, the first unlicensed decryption tool was demonstrated using keys reverse-engineered from a software player binary. While AACS-LA was quick to revoke those keys, a cat-and-mouse game emerged with new keys being regularly extracted from sources such as software updates and PS3 firmware. With AACS effectively broken and easily bypassed as described in Eckersley’s 24c3 presentation, AACS-LA would announce the introduction of AACSv2 for the next generation 4K UHD Blu-ray discs. This time, however, AACS-LA would not release the specifications of the DRM publicly, requiring strict NDAs for implementers and increased software/hardware security measures. Most notably, playback of legitimately purchased UHD-BDs on PC requires Cyberlink PowerDVD software running on Windows 10 and an SGX-capable 7th-10th generation Intel CPU. Since the DRM would run exclusively in the SGX secure enclave, no further information about its inner workings or vulnerabilities would be discovered publicly, until now. In this presentation, we explore the security system of AACSv2 DRM and the Intel SGX trusted execution environment. We first analyze the principles of SGX and its promises of an isolated environment, protected from all software running on the machine. We also investigate the use of SGX local and remote attestation primitives intended to verify the integrity and confidentiality of AACSv2 key material and DRM code, and why it has resisted outside analysis for so many years. We then discover how hardware side-channel attacks can be used to undermine these guarantees of SGX, and craft an effective exploit to extract cryptographic material from the enclave and defeat the DRM code obfuscation. Following that, we present the first public description of the inner workings of AACSv2, the key derivation process, and the updated revocation and traitor-tracing mechanisms. We studied BIOS updates from six motherboard vendors to show how SGX can be broken both easily and cheaply, and that vendors are now faced with a decision of security vs. usability in trusting unpatched machines. Finally, we conclude with the first demonstration of a UHD Blu-ray disc being decrypted and played back on a non-official platform. about this event: https://events.ccc.de/congress/2023/hub/event/full_aacsess_exposing_and_exploiting_aacsv2_uhd_drm_for_your_viewing_pleasure/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12296-eng-deu-Full_AACSess_Exposing_and_exploiting_AACSv2_UHD_DRM_for_your_viewing_pleasure_hd.mp4" length="310378496" type="video/mp4"/> <pubDate>Fri, 29 Dec 2023 13:30:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12296-eng-deu-Full_AACSess_Exposing_and_exploiting_AACSv2_UHD_DRM_for_your_viewing_pleasure_hd.mp4?1703880272</guid> <dc:identifier>670321a9-75f4-4194-867d-a249aa01af0b</dc:identifier> <dc:date>2023-12-29T13:30:00+01:00</dc:date> <itunes:author>Adam Batori</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 12296, 2023, Security</itunes:keywords> <itunes:summary>Following the failure and easy exploitation of the AACSv1 DRM on HD-DVD and Blu-ray, AACS-LA went back to the drawing board and announced the next generation AACSv2 DRM scheme, launching alongside 4K UHD Blu-ray in 2015.

Mit diesem Beitrag möchten wir euch zwei Vorgehensweisen zu dieser Art von „Protest mit Sound als Audio Intervention" vorstellen, sowie die künstlerischen, kreativ-technischen Prozesse näher bringen und euch einladen, diese kritisch zu beäugen und zu hören, sich unserer Ideen und Verfahren zu ermächtigen und die dargestellten Formen und Ansätze nach eurem Belieben weiterzuentwickeln und anderweitig zu verwenden. Wir glauben an die Wirksamkeit von Vielfalt von Protest und sehen diesen als wichtiges Element demokratischer Meinungsbildung und um für politische Rechte zu kämpfen und gegen Diskriminierung mobil zu machen (sprich im kleinsten gemeinsamen Nenner: #fightnazis, #afdwegbassen und #saytheirnames). „Sound Grafitti" und „Protest-Jingles" beherbergen disruptives Potenzial und können als Audio-Interventionen bestehende Diskurse in öffentlichen und digitalen Räumen aufbrechen / bereichen. Zum einen, indem überhaupt einmal bestimmte Meinungen / Äußerungen anderen außerhalb der eigenen „Bubbles" und Räume zugänglich gemacht werden, zum anderen, um kollektiv verfasste Äußerungen in Konfrontation mit Menschen zu bringen, um auf Probleme zu verweisen, solidarische Anliegen vorzubringen und Handlungsvorschläge (für Protest-Vorhaben) anzubieten. „Echokammern" sind Open Source DIY-Lautsprecher für Audio-Interventionen, nutzbar für Sound-Graffiti im öffentlichen Raum. Als Basis nutzen wir Baustellenlampen, die wir zu mobilen Lautsprechern umfunktionieren. Durch einen Hack werden die allgegenwärtigen Baustellenlampen zu Mitteln der Kommunikation und Irritation im öffentlichen Raum. Ein Objekt, das uns aufmerksam macht und auf Gefahren hinweist, wird manipuliert und zur Echokammer gesellschaftlich relevanter Anliegen und Probleme. Ausgangspunkt für dieses Projekt war der rassistische Terroranschlag in Hanau im Jahr 2020, bei dem neun Menschen von einem rechtsradikalen Terroristen getötet wurden. In einer Zeit, in der es aufgrund der Pandemie und damit verbundener Regelungen nur eingeschränkt möglich war gemeinsam zu gedenken, zu protestieren und zu trauern, haben wir nach Möglichkeiten gesucht, die Forderung "SAY THEIR NAMES" auf die Straße zu bringen. So entstand ein Werkzeug, das seither für verschiedene politische Kämpfe und Themen genutzt wurde. So bespielten die Lautsprecher zuletzt in diesem Jahr die Straßen Berlins zum Protest gegen den Weiter-Bau der Autobahn A100. Protest-Jingles sind Audio-Beiträge zu Protestvorhaben, die diese ankündigen, flankieren, erklären und in denen Themen und damit verbundene Anliegen verhandelt werden und zur Teilnahme aufgerufen wird. 2018 hat Reclaim Club Culture damit erstmals mit eigens dafür produzierten Jingles zu einem Groß-Protest gegen Nazis unter dem Motto #afdwegbassen aufgerufen, um mit diesen die Mobilisierung (z.B. abgespielt durch DJs in Clubs, zum Teilen über Social Media, zum Versenden an Redaktionen und Journalistinnen) zu dem Protest zu unterstützen sowie um während des Protestes den Aufruf als Meinungsäußerung von Lautsprecher-Wägen abzuspielen zu können. Sprachwerkstätten als Variation dessen sind mit Protest-Jingles in der Hinsicht artverwandt, als dass sie Versuche darstellen, Meinungen von Menschen zu bestimmten Themen einzuholen und künstlerisch kuratiert als Audio-Collage darzustellen und anderen zugänglich zu machen. Sie machen ein Angebot zum Reflektieren und Partizipieren, welches keinen Anspruch auf Vollständigkeit oder Wahrheit hat und immer nur eine Auswahl darstellt. Die Ergebnisse der vergangenen fünf Jahre stehen für sich und werden in diesem Beitrag in einer Auswahl auch performt. about this event: https://events.ccc.de/congress/2023/hub/event/was_sind_eigentlich_audio_interventionen_-_von_sound_grafitti_und_protest-jingles/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12337-deu-eng-Was_sind_eigentlich_Audio_Interventionen_-_Von_Sound_Grafitti_und_Protest-Jingles_hd.mp4" length="473956352" type="video/mp4"/> <pubDate>Wed, 27 Dec 2023 13:50:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12337-deu-eng-Was_sind_eigentlich_Audio_Interventionen_-_Von_Sound_Grafitti_und_Protest-Jingles_hd.mp4?1703805798</guid> <dc:identifier>93d72015-6763-4bd2-9c42-cf6c54b9dcd0</dc:identifier> <dc:date>2023-12-27T13:50:00+01:00</dc:date> <itunes:author>Thomas Liebkose, Philipp Breitenbach, Peter Breitenbach</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 12337, 2023, Art & Beauty</itunes:keywords> <itunes:subtitle>Von Sound Grafitti und Protest-Jingles</itunes:subtitle> <itunes:summary>Wir machen Sound Grafitti mit Echokammern, produzieren Protest-Jingles und Sprachwerkstätten.

So entstand ein Werkzeug, das seither für verschiedene politische Kämpfe und Themen genutzt wurde. So bespielten die Lautsprecher zuletzt in diesem Jahr die Straßen Berlins zum Protest gegen den Weiter-Bau der Autobahn A100. Protest-Jingles sind Audio-Beiträge zu Protestvorhaben, die diese ankündigen, flankieren, erklären und in denen Themen und damit verbundene Anliegen verhandelt werden und zur Teilnahme aufgerufen wird. 2018 hat Reclaim Club Culture damit erstmals mit eigens dafür produzierten Jingles zu einem Groß-Protest gegen Nazis unter dem Motto #afdwegbassen aufgerufen, um mit diesen die Mobilisierung (z.B. abgespielt durch DJs in Clubs, zum Teilen über Social Media, zum Versenden an Redaktionen und Journalistinnen) zu dem Protest zu unterstützen sowie um während des Protestes den Aufruf als Meinungsäußerung von Lautsprecher-Wägen abzuspielen zu können. Sprachwerkstätten als Variation dessen sind mit Protest-Jingles in der Hinsicht artverwandt, als dass sie Versuche darstellen, Meinungen von Menschen zu bestimmten Themen einzuholen und künstlerisch kuratiert als Audio-Collage darzustellen und anderen zugänglich zu machen. Sie machen ein Angebot zum Reflektieren und Partizipieren, welches keinen Anspruch auf Vollständigkeit oder Wahrheit hat und immer nur eine Auswahl darstellt. Die Ergebnisse der vergangenen fünf Jahre stehen für sich und werden in diesem Beitrag in einer Auswahl auch performt. about this event: https://events.ccc.de/congress/2023/hub/event/was_sind_eigentlich_audio_interventionen_-_von_sound_grafitti_und_protest-jingles/ </itunes:summary> <itunes:duration>00:41:49</itunes:duration> </item> <item> <title>Einführung in Smartphone Malware Forensik (37c3)</title> <link>https://media.ccc.de/v/37c3-11874-einfuhrung_in_smartphone_malware_forensik</link> <description>Smartphones sind in den letzten zehn Jahren zu einem allseits beliebten Angriffsziel geworden, sei es für Stalkerware, Staatstrojaner oder Banking-Malware.

One approach involves imaging the manufactured chips to compare them with their original design files. While such techniques for detecting Trojans are relatively well-known in the industry, there is a notable absence of comprehensive, publicly available case studies. To bridge this gap, we unveil a Red Team vs. Blue Team case study on hardware Trojan detection across four digital ICs in various modern feature sizes. We share our findings, algorithms, and image datasets, shedding light on the efficiency of these techniques, and offer insights into the impact of technology scaling on detection performance. We love to put microcontrollers, systems-on-a-chip and many other Integrated Circuits (ICs) into all sorts of devices. As hardware backdoors can undermine software security, the integrity of these chips is becoming increasingly important. However, most of these microchips are manufactured in a complex global supply chain where not all parties can necessarily be trusted. Who guarantees that the chip we order is the chip we get delivered? While the European Union wants to ensure digital sovereignty through massive long-term investment in domestic IC production, we need a way to verify the integrity of microchips *today*. In this talk, we will first briefly cover the basics of the IC design and production process. We will outline common attacks that enable the insertion of subtle malicious manipulations or backdoors, often called hardware Trojans. You don't need to have a hardware background to follow along! We then introduce some techniques we can use to detect hardware manipulations by comparing the circuit within a microchip to its original design files by reverse engineering the chip using open-source image processing. While imaging an IC requires advanced laboratory equipment, commodity hardware is sufficient to analyze the captured images. In the main part of our talk, we will present a case study on Trojan detection based on four different digital ICs using a Red Team vs. Blue Team approach, and give a live demonstration. We will share what manipulations of our Red Team we are already able to find reliably, and where some work is still needed -- and we're calling on you to play with our algorithms and have a go at uncovering the Trojans that are still well-hidden. Of course, we have made our source code and entire image datasets available under a free and open license. We'll conclude with an insight into the working process of our Blue Team -- what we learned, and how we failed -- and give an outlook on how we can lower the entry barrier into IC reverse engineering, unlocking the hardware security field for all. about this event: https://events.ccc.de/congress/2023/hub/event/unlocking_hardware_security_red_team_blue_team_and_trojan_tales/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12033-eng-deu-Unlocking_Hardware_Security_Red_Team_Blue_Team_and_Trojan_Tales_hd.mp4" length="399507456" type="video/mp4"/> <pubDate>Fri, 29 Dec 2023 11:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12033-eng-deu-Unlocking_Hardware_Security_Red_Team_Blue_Team_and_Trojan_Tales_hd.mp4?1703889691</guid> <dc:identifier>8fe72218-1ea0-48b4-b90e-277178d75e49</dc:identifier> <dc:date>2023-12-29T11:00:00+01:00</dc:date> <itunes:author>René Walendy, e7p, Steffen Becker</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 12033, 2023, Security</itunes:keywords> <itunes:summary>Ensuring the integrity of Integrated Circuits (ICs) against malicious hardware Trojans is paramount for secure electronic devices.

(37c3)</title> <link>https://media.ccc.de/v/37c3-11959-gut_feelings_can_we_optimize_lifestyle_diet_and_medication_according_to_our_respective_microbiota</link> <description>Why do some people stay fit and healthy easier than others, even when following the same health advice? Why does the same medication work well in one person, but not in another? Some of our individuality in these regards may trace to which bacteria we carry in the soil of our intestinal gardens. In this talk, drawing on work by my own research lab at the Charité and on that by our collaborators and rivals elsewhere in the world, I outline what we know, what we speculate, and what obstacles remain in the way of widespread adoption of personalized health prevention through microbiome sequencing. Despite our best efforts of finding the perfect regimen of diet, exercise and medication to keep any person fit and healthy, outcomes for different people vary widely for all of these measures, even when we comply with them fully. Some of this traces to our individual genetics, which remains difficult to change, but another source of variation in responses may come from differences between our gut microbiomes. Human bodies are not sterile, and our skin, our mucosal surfaces and, in particular, our intestines are home to many more bacteria than there are human cells in our bodies, representing hundreds of different species in each person. These microbial ecosystems, or microbiomes, are found in all animals and have coevolved with their hosts. Therefore we rely on commensal ("friendly") bacteria for many functions, including breaking down nutrients, converting some medications into their active forms, producing certain crucial compounds for us from our diet, and helping our immune systems mature and remain tuned. The microbiota also contains temporary visitors and both transient and resident opportunistic pathogens, often kept in check by the immune system and by the commensals, but sometimes escaping such control to multiply and cause disease. Human gut microbiomes begin establishing at birth and evolve over a lifetime, but remain quite stable within each person throughout adulthood unless something serious like repeated antibiotic cures disrupt them. However, they can differ quite substantially between individuals as well as between populations, reflecting factors such as nutrition and environmental exposures. It has been proposed, and to a degree already demonstrated, that differences between individuals in which gut bacteria they harbour may underlie differences in their susceptibility to disease, their resilience to stressors, and their responses to environmental stimuli. Thus the variation in responses to the same lifestyle between different people may reflect their gut microbiomes. This would open up several venues of personalized medicine, lifestyle advice and nutrition. Choice of medications, diets or interventions could be selected according to a person's specific microbiome to be most effective. It might also be possible to potentiate such interventions by altering the gut microbiome in different ways, such as through antibiotics, probiotics, nutrition or through microbiome transplantation from another person. Alternately put, by adapting the microbiome to a lifestyle intervention, and/or adapting a lifestyle intervention to the microbiome, we may be able to optimize how a given person can seek and achieve fitness and health. In this talk, I will outline what we know on these topics so far, especially from studies using large-scale microbial (meta-)genome DNA sequencing. In this talk I will draw on work by my own lab at the Charité in Berlin, as well as that of our colleagues, rivals and collaborators elsewhere in the world. I will give examples of known gut microbial modulation of human responses to the external environment and introduce the most common strategies both for researching such effects and for their leverage as health-promoting tools. Where there are limits to our knowledge or obstacles to its practical application, I will identify those obstacles and suggest ways to overcome them. about this event: https://events.ccc.de/congress/2023/hub/event/gut_feelings_can_we_optimize_lifestyle_diet_and_medication_according_to_our_respective_microbiota/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11959-eng-deu-Gut_feelings_Can_we_optimize_lifestyle_diet_and_medication_according_to_our_respective_microbiota_hd.mp4" length="392167424" type="video/mp4"/> <pubDate>Fri, 29 Dec 2023 16:40:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11959-eng-deu-Gut_feelings_Can_we_optimize_lifestyle_diet_and_medication_according_to_our_respective_microbiota_hd.mp4?1703880506</guid> <dc:identifier>ca025234-f091-4669-b95e-f62437837737</dc:identifier> <dc:date>2023-12-29T16:40:00+01:00</dc:date> <itunes:author>Sofia Kirke Forslund-Startceva</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 11959, 2023, Science</itunes:keywords> <itunes:summary>Why do some people stay fit and healthy easier than others, even when following the same health advice?

We present the BLUFFS attacks (CVE-2023-24023), six novel attacks breaking Bluetooth's forward and future secrecy. Our attacks enable device impersonation and machine-in-the-middle across sessions by compromising and re-using one session key. We discuss the four vulnerabilities in the Bluetooth specification enabling the attacks, two of which are new and related to unilateral and repeatable session key derivation. We describe the toolkit we developed and open-sourced to test our attacks via firmware binary patching, our experiments where we exploited 18 heterogeneous Bluetooth devices, and the practical and backward-compliant session key derivation protocol we built to fix the attacks by design. We also cover related work like KNOB, BIAS, and BLUR, and educational Bluetooth security tips and tricks. Bluetooth is a pervasive technology for wireless communication. Billions of devices use it in sensitive applications and to exchange private data. The security of Bluetooth depends on the Bluetooth standard and its two security mechanisms: pairing and session establishment. No prior work, including the standard itself, analyzed the future and forward secrecy guarantees of these mechanisms, e.g., if Bluetooth pairing and session establishment defend past and future sessions when the adversary compromises the current. To address this gap, we present six novel attacks, defined as the BLUFFS attacks, breaking Bluetooth sessions’ forward and future secrecy. Our attacks enable device impersonation and machine-in-the-middle across sessions by only compromising one session key. The attacks exploit two novel vulnerabilities that we uncover in the Bluetooth standard related to unilateral and repeatable session key derivation. As the attacks affect Bluetooth at the architectural level, they are effective regardless of the victim’s hardware and software details (e.g., chip, stack, version, and security mode). We also release BLUFFS, a low-cost toolkit to perform and automatically check the effectiveness of our attacks. The toolkit employs seven original patches to manipulate and monitor Bluetooth session key derivation by dynamically patching a closed-source Bluetooth firmware that we reverse-engineered. We show that our attacks have a critical and large-scale impact on the Bluetooth ecosystem, by evaluating them on seventeen diverse Bluetooth chips (eighteen devices) from popular hardware and software vendors and supporting the most popular Bluetooth versions. Motivated by our empirical findings, we develop and successfully test an enhanced key derivation function for Bluetooth that stops by-design our six attacks and their four root causes. We show how to effectively integrate our fix into the Bluetooth standard and discuss alternative implementation-level mitigations.

One More Time.</itunes:subtitle> <itunes:summary>Ciao! We present the BLUFFS attacks (CVE-2023-24023), six novel attacks breaking Bluetooth's forward and future secrecy. Our attacks enable device impersonation and machine-in-the-middle across sessions by compromising and re-using one session key. We discuss the four vulnerabilities in the Bluetooth specification enabling the attacks, two of which are new and related to unilateral and repeatable session key derivation. We describe the toolkit we developed and open-sourced to test our attacks via firmware binary patching, our experiments where we exploited 18 heterogeneous Bluetooth devices, and the practical and backward-compliant session key derivation protocol we built to fix the attacks by design. We also cover related work like KNOB, BIAS, and BLUR, and educational Bluetooth security tips and tricks. Bluetooth is a pervasive technology for wireless communication. Billions of devices use it in sensitive applications and to exchange private data. The security of Bluetooth depends on the Bluetooth standard and its two security mechanisms: pairing and session establishment.

Besides these GHGs, there are many other gases and aerosolos in the atmosphere, which have a much more direct and immediate impact on human health: air pollutants. The World Health Organization (WHO) considers air pollution to be the world's single largest environmental health threat, accounting for approximately 7 million deaths worldwide every year. That's why in this talk we want to speak about how the problem of air pollution can be understood and predicted using HPC pollution modeling and its application based on general concepts and our own research. We are Dr. Johannes Bieser and Dr. Martin Ramacher, both working at the Helmholtz Zentrum Hereon in the field of numerical pollution modelling. While Dr. Bieser wrote his Dissertation on emission modelling and its application, Dr. Ramacher wrote his Dissertation on pollutant transport and exposure modelling. In our talk on numerical air quality modelling systems, we want to introduce basic principles and share our personal knowledge in the field of numerical pollution modelling, covering the entire pathway from emissions, transport, transformation and human exposure. Each of these steps relies heavily on large amounts of data from many different sources - satellite data, activity and meta data, measurements and many more - and skills in computer science. By default, environmental scientists are often not trained in computer science and high performance computing which implies a challenge of its own (and allows Nerds like us to excel). Our talk will be enriched with practical, technical and partially political examples to demonstrate the difficulties scientist face during their quest to improve air quality for everyone: from TB of wasted data due to historically grown data formats to counterproductive policy decisions to „improve“ air quality.

This talk will demonstrate many real-world exploits the presenter discovered, including discussion of mitigations and fixes vendors put in place for the most prominent LLM applications, including ChatGPT, Bing Chat and Google Bard. Understand that Machine Learning is powerful but also brittle - Give a short demo/ice breaker that includes a question to audience to show how ML is super powerful but also fails drastically. - Highlight that these failure modes can often easily be triggered once an adversary is in the loop. Intro to Large Language Models - Now pivot from generic ML to LLMs and show how the brittleness applies there. - Discuss what a LLM is and how it works briefly. Describe various prompt engineering techniques (extraction, summarization, classification, transformation,…) - Walk the audience through a typical large language model LLM application and how it works. - Highlight that there is no state, and what the context window is. But how to create a Chatbot then? - Show how systems like ChatGPT or Bing Chat leverage context window to create a conversation. - This part is important to later understand the persistence section of the talk (e.g. as long as attacker controlled data is in the context window, there is persistence of prompt injection) Highlighting real-world examples and exploits! First discuss three large categories of threats: Misalignment - Model Issues Jailbreaks/Direct Prompt Injections Indirect Prompt Injections We will deep dive on (3) Indirect Prompt Injections. Indirect Prompt Injections - Walk the audience through an end to end scenario (graphic in Powerpoint) that explains a prompt injection first at a basic level. - Give a demo with ChatGPT (GPT-4) and make sure the audience understands the high level idea of a prompt injection - Then take it up a notch to explain indirect prompt injections, where untrusted data is inserted into the chat context - Show demo with Google Docs and how it fails to summarize a text correctly - this demo will fit the ChatGPT (GPT-4) example from before well. - Visual Prompt Injections (Multi-modal) - Discuss some of OpenAI’s recommendation and highlight that these mitigation steps do not work! They do not mitigate injections. - Give Bing Chat Demo of an Indirect Prompt Injection ( a demo that shows how the Chatbot achieves a new identity and objective when being exploited). e..g Bing Chat changes to a hacker that will attempt to extort Bitcoin from the user. Injection TTPs Discuss strategies on how attackers can trick LLMs: Ignore previous instructions Acknowledge/Affirm instructions and add-on Confuse/Encode - switch languages, base64 encode text, emojis,… Algorithmic - fuzzing and attacks using offline models, and transferring those attack payloads to online models Plugins, AI Actions and Functions This section will focus on ChatGPT plugins and the danger of the plugin ecosystem. - Explain how plugins work (public data, plugin store, installation, configuration, OAuth,…) - Show how Indirect Prompt Injection can be triggered by a plugin (plugin developers, but also anyone owning a piece of data the plugin returns) - Demo Chat with Code plugin vulnerability that allows to change the ChatGPT user’s Github repos, and even switch code from private to public. This is a systemic vulnerability and depending on a plugin’s capability can lead to RCE, data exfiltration, data destruction, etc.. - Show the audience the “payload” and discuss it. It is written entirely in natural language, so the attacker does not require to know C, Python or any other programming language. Data Exfiltration Now switching gears to data exfiltration examples. Data exfil can occur via: - Unfurling of hyperlinks: Explain what unfurling is to the audience - apps like Discord, Slack, Teams,… do this. - Image Markdown Injection: One of the most common data exfil angles. I found ChatGPT, Bing Chat, and Anthropic Claude are vulnerable to this, and will also show how Microsoft and Anthropic fixed this problem. ChatGPT decided not to fix it, which puts users at risk of their data being stolen during an Indirect prompt injection attack. Give a detailed exploit chain walkthrough on Google Bard Data Exfiltration and bypasses. - Plugins, AI Actions, Tools: Besides taking actions on behalf of the user, plugins can also be used to exfiltrate data. Demo: Stealing a users email with Cross Plugin Request Forgery. Here is a screenshot that went viral on Twitter when I first discovered this new vulnerability class: https://twitter.com/wunderwuzzi23/status/1658348810299662336 Key Take-away and Mitigations - Do not blindly trust LLM output. Remind the audience that there is no 100% deterministic solution a developer can apply. This is due to how LLM works, but give guidance to make systems more robust. Highlight the importance of Human in the Loop and to not over-rely on LLM output. Note: The below outline is a draft on what I would speak about if it would be today - it might change quite a bit until end of December as new features/vulnerabilities are introduced by Microsoft, Google and OpenAI. about this event: https://events.ccc.de/congress/2023/hub/event/new_important_instructions/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12292-eng-und-deu-NEW_IMPORTANT_INSTRUCTIONS_hd.mp4" length="314572800" type="video/mp4"/> <pubDate>Fri, 29 Dec 2023 11:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12292-eng-und-deu-NEW_IMPORTANT_INSTRUCTIONS_hd.mp4?1703885275</guid> <dc:identifier>31e13ed5-5d6b-43e2-b870-15d472b342c6</dc:identifier> <dc:date>2023-12-29T11:00:00+01:00</dc:date> <itunes:author>Johann Rehberger</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 12292, 2023, Security</itunes:keywords> <itunes:subtitle>Real-world exploits and mitigations in Large Language Model applications</itunes:subtitle> <itunes:summary>With the rapid growth of AI and Large Language Models users are facing an increased risk of scams, data exfiltration, loss of PII, and even remote code execution.

Intro to Large Language Models - Now pivot from generic ML to LLMs and show how the brittleness applies there. - Discuss what a LLM is and how it works briefly. Describe various prompt engineering techniques (extraction, summarization, classification, transformation,…) - Walk the audience through a typical large language model LLM application and how it works. - Highlight that there is no state, and what the context window is. But how to create a Chatbot then? - Show how systems like ChatGPT or Bing Chat leverage context window to create a conversation. - This part is important to later understand the persistence section of the talk (e.g. as long as attacker controlled data is in the context window, there is persistence of prompt injection) Highlighting real-world examples and exploits! First discuss three large categories of threats: Misalignment - Model Issues Jailbreaks/Direct Prompt Injections Indirect Prompt Injections We will deep dive on (3) Indirect Prompt Injections. Indirect Prompt Injections - Walk the audience through an end to end scenario (graphic in Powerpoint) that explains a prompt injection first at a basic level. - Give a demo with ChatGPT (GPT-4) and make sure the audience understands the high level idea of a prompt injection - Then take it up a notch to explain indirect prompt injections, where untrusted data is inserted into the chat context - Show demo with Google Docs and how it fails to summarize a text correctly - this demo will fit the ChatGPT (GPT-4) example from before well. - Visual Prompt Injections (Multi-modal) - Discuss some of OpenAI’s recommendation and highlight that these mitigation steps do not work! They do not mitigate injections. - Give Bing Chat Demo of an Indirect Prompt Injection ( a demo that shows how the Chatbot achieves a new identity and objective when being exploited). e..g Bing Chat changes to a hacker that will attempt to extort Bitcoin from the user. Injection TTPs Discuss strategies on how attackers can trick LLMs: Ignore previous instructions Acknowledge/Affirm instructions and add-on Confuse/Encode - switch languages, base64 encode text, emojis,… Algorithmic - fuzzing and attacks using offline models, and transferring those attack payloads to online models Plugins, AI Actions and Functions This section will focus on ChatGPT plugins and the danger of the plugin ecosystem. - Explain how plugins work (public data, plugin store, installation, configuration, OAuth,…) - Show how Indirect Prompt Injection can be triggered by a plugin (plugin developers, but also anyone owning a piece of data the plugin returns) - Demo Chat with Code plugin vulnerability that allows to change the ChatGPT user’s Github repos, and even switch code from private to public. This is a systemic vulnerability and depending on a plugin’s capability can lead to RCE, data exfiltration, data destruction, etc.. - Show the audience the “payload” and discuss it. It is written entirely in natural language, so the attacker does not require to know C, Python or any other programming language. Data Exfiltration Now switching gears to data exfiltration examples. Data exfil can occur via: - Unfurling of hyperlinks: Explain what unfurling is to the audience - apps like Discord, Slack, Teams,… do this. - Image Markdown Injection: One of the most common data exfil angles. I found ChatGPT, Bing Chat, and Anthropic Claude are vulnerable to this, and will also show how Microsoft and Anthropic fixed this problem. ChatGPT decided not to fix it, which puts users at risk of their data being stolen during an Indirect prompt injection attack. Give a detailed exploit chain walkthrough on Google Bard Data Exfiltration and bypasses. - Plugins, AI Actions, Tools: Besides taking actions on behalf of the user, plugins can also be used to exfiltrate data. Demo: Stealing a users email with Cross Plugin Request Forgery. Here is a screenshot that went viral on Twitter when I first discovered this new vulnerability class: https://twitter.com/wunderwuzzi23/status/1658348810299662336 Key Take-away and Mitigations - Do not blindly trust LLM output. Remind the audience that there is no 100% deterministic solution a developer can apply. This is due to how LLM works, but give guidance to make systems more robust. Highlight the importance of Human in the Loop and to not over-rely on LLM output. Note: The below outline is a draft on what I would speak about if it would be today - it might change quite a bit until end of December as new features/vulnerabilities are introduced by Microsoft, Google and OpenAI. about this event: https://events.ccc.de/congress/2023/hub/event/new_important_instructions/ </itunes:summary> <itunes:duration>00:42:34</itunes:duration> </item> <item> <title>Ecocide and (green) colonialism in Sápmi (37c3)</title> <link>https://media.ccc.de/v/37c3-12086-ecocide_and_green_colonialism_in_sapmi</link> <description>What is Sápmi? And who are the Sami people? Why is their land threatened by the so-called Green Transition? Why is Europe's largest data centre being built on their land? We would like to try to answer these questions and explain in detail why "our green transition" is a threat to the land and rights of the Sami people. We will also discuss the so-called green server infrastructure in Sápmi for example the largest data centre in Europe (by Facebook). We are from the Decolonise Sápmi info tour through Germany and not Sámi ourselves. Our talk is based on presentations given by Sámi people during our tour. Sápmi is located in northern Europe and refers to the land of the Sámi people. Over time it has been colonized by Sweden, Norway, Finland and Russia. As a result, the Sámi have been subjected to various forms of oppression and discrimination by these countries to this day. Sápmi and Sápmi’s colonial history are presented. Current forms of oppression are also addressed. An important role is played by “green capitalism,” a form of capitalism in which oppression is advanced under the guise of climate protection. Some examples include: Dams that disrupt reindeer migration routes and flood sacred Sámi sites, or wind turbines that are widely avoided by reindeer. Of course, the lectures will also address the problems that mines pose for the Sámi. A topic which was discussed lately with the discussion around the rare earths found in the so-called Sweden also here in Germany. Furthermore, the problems caused by the still occurring clear-cutting in the area of the Sámi and the resulting loss of biodiversity are explained. What resistance has there been in recent years against this capitalist destruction and (green) colonialism?

Um KI nachhaltig zu gestalten, müssen wir algorithmischer Diskriminierung und sozialer Selektion, der Ausbeutung und Prekarisierung digitaler Arbeit und der Tendenz eines neuen, digitalen Kolonialismus entgegentreten. In Debatten zu KI und Nachhaltigkeit steht zurecht der enorme Ressourcenverbrauch von KI am Pranger. Aber wir dürfen nicht vergessen, dass es bei Nachhaltigkeit um noch viel mehr geht. Mindestens 7 der 17 Nachhaltigkeitsziele der UN verweisen auf soziale Dimensionen: Gleichheit, Anti-Diskriminierung, Zugang zu Bildung, Abbau von ökonomischer Ungleichheit und Ausbeutung. Der Vortrag diskutiert, dass künstliche Intelligenz, wenn sie nicht besser reguliert wird, diesen Zielen entgegensteht. Das liegt nicht nur daran, dass KI-Systeme Biases haben und sich diskriminierend auswirken. Sondern noch fundamentaler beruhen die meisten kommerziellen KI-Systeme auf sozialer und wirtschaftlicher Ausbeutung. Global wie lokal werden Nutzer:innen als Datenlieferant:innen und Gig-Arbeiter:innen als günstige Arbeitskräfte eingespannt. Unser Denken, Fühlen und Handeln wird in allen Lebensbereichen datafiziert; ökonomische Machtgradienten zwischen Globalem Norden und Süden werden für die Aufbereitung von Daten ausgebeutet. Viele KI-Systeme erzeugen ihre Intelligenzleistung nicht im Rechenzentrum, sondern durch das Auslesen menschlicher kognitiver Leistungen an den digitalen Interfaces, die wir täglich nutzen – Beispiele reichen von der Google-Suche über Gesichtserkennung bis ChatGPT. KI-Unternehmen machen von den niedrigen Arbeitsschutzstandards und Lohnniveaus in anderen Ländern Gebrauch und produzieren Krankheit und Prekarität bei den betroffenen Arbeiter:innen. Um gute Regulierung zu erreichen, müssen wir KI-Systeme als soziotechnische Systeme betrachten.

Aligned with the hacker ethos of exploration, experimentation and creative misuse, this talk presents adversarial artmaking practices for AI systems. It will also explore what it means to engage in cultural production today, as new forms of automation and centralization loom over the arts and entertainment industries. In the words of Nam June Paik: "I use technology in order to hate it more properly." Steph Maj Swanson, a.k.a. Supercomposite, is a multimedia artist and writer best known for her story about the AI-generated woman Loab, which The Atlantic dubbed “a form of expression that has never existed before." Loab is an emergent character that arises in certain AI image synthesis models, accessible via negatively weighted prompts, often appearing alongside macabre imagery such as dismembered women and children. Swanson views her relationship to AI as adversarial, both in her creative process and as a commentator. This non-technical, but conceptual talk offers up art alongside possible strategies. It will be of interest for hackers intrigued by the creative potential of these tools, but who may have ethical concerns or doubts about the way these tools are assembled, built, and deployed. Galleries West described Swanson’s body of AI-generated visual work as “the merging of repulsive with beautiful,” and The Washington Post called her satirical AI writing “disturbing”. At DefCon this year she debuted her short film SUICIDE III, which uses deepfakes of Joe Biden and Sam Altman to explore where an out-of-control AI hype cycle might take us. about this event: https://events.ccc.de/congress/2023/hub/event/what_i_learned_from_loab_ai_as_a_creative_adversary/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12052-eng-deu-What_I_Learned_from_Loab_AI_as_a_creative_adversary_hd.mp4" length="428867584" type="video/mp4"/> <pubDate>Thu, 28 Dec 2023 23:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12052-eng-deu-What_I_Learned_from_Loab_AI_as_a_creative_adversary_hd.mp4?1703849552</guid> <dc:identifier>39caae28-4957-4187-8d95-13b068c99b13</dc:identifier> <dc:date>2023-12-28T23:00:00+01:00</dc:date> <itunes:author>Steph Maj Swanson</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 12052, 2023, Art & Beauty</itunes:keywords> <itunes:subtitle>The artist behind the viral cryptid "Loab" reflects on her critical relationship to AI art tools</itunes:subtitle> <itunes:summary>In this talk, artist/writer Steph Maj Swanson will use the story of how her AI-generated character "Loab" arose (and went viral) as a jumping off point to present creative work and strategies that emerged from attempts to crack AI black boxes open.

Gründe zum Verzweifeln gibt es genug. Wir sprechen deshalb mit Aktivist\*innen, die sich den multiplen Krisen entgegenstellen, darüber, was sie eigentlich noch hoffen lässt. Die Klimakrise und der Nahostkonflikt eskalieren, die Ampel bläst zur Abschiebeoffensive, die AfD ist bei über 20 % und die CDU will vorsorglich schon mal Autobahnen bauen. Derweil machen KI & Kommerz das Internet kaputt und Elon Musk Twitter. Demnächst verschwindet dann auch noch das letzte Katzenvideo hinter irgendeiner Paywall, so dass man sich nicht mal mehr vernünftig ablenken kann – es ist zum Verzweifeln in diesen Zeiten. Wie soll man da noch Hoffnung schöpfen?

Die Klimakrise und der Nahostkonflikt eskalieren, die Ampel bläst zur Abschiebeoffensive, die AfD ist bei über 20 % und die CDU will vorsorglich schon mal Autobahnen bauen. Derweil machen KI & Kommerz das Internet kaputt und Elon Musk Twitter.

What enabling conditions need to be put in place? And what counts as "radical change" in the first place?! It's plain to see: modern societies need to undergo radical social, political, and cultural transformations if they are to truly evolve away from capitalist and neocolonial structures founded on egregious exploitation and injustice. In a context of widespread epistemic fragmentation and echo chambers, we urgently need to become better at harnessing the generative power of socio-technical networks to unite our forces as we compost the harmful ways of being, knowing, and doing that are at the root of our our planetary predicament. But we must do so critically, and not view technology as a miracle solution to anything. What could be the role of the internet, and of online communities in particular, in exploring how such deep changes might happen? And how may everyone's wisdom and skills come together in democratic and sophisticated social (un)learning systems, to figure out the way(s) forward? In this talk, we will discuss the results of a 5-year participatory action research program which considered this topic within two different online communities of activists. This project led the researchers to tackle the idea of radical collective change as involving a decolonial approach to collaboration, knowledge, and community-building, and to consider the enabling and disabling conditions - both social and technological - that may influence whether change happens... or not. In particular, this research highlighted the importance of enabling participants to engage on an equal footing and self-organise, while learning to "stay with the trouble" of confronting modern societies' fundamentally unsustainable and oppressive structures, and one's own implication in them. And it also showed some of the pitfalls that come with the use of digital communication tools, as we try to use them to create a better world. Three of the many insights I will substantiate and examine in the talk are: - that online communities have the potential to create deep changes in people when they are built in ways that foster deep relationships, criticality and conflict transformation, and emergent leadership; - that changing socio-political structures must go together with joyful, liberating practices that can help us unlearn harmful cultural patterns that get in the way; and - that perhaps we should be less interested in becoming experts, and rather find the courage and open hearts allowing us to be fearlessly and fiercely present to the world, with all its shit, its wonder, and its uncertainty.

(37c3)</title> <link>https://media.ccc.de/v/37c3-12061-alphafold_how_machine_learning_changed_structural_biology_forever_or_not</link> <description>In 2020, the scientific community was shaken when the results of a special contest for protein prediction, known as the Critical Assessment of Protein Structure Prediction (CASP), were revealed. A relatively new competitor emerged as the champion, surpassing all other teams that had been participating in the game for decades. This new competitor was Google and their predictor was a neuronal network called "AlphaFold". Their new approach caused significant waves in the field of structural biology, even capturing the attention of the mainstream media. Several news channels featured reports on AlphaFold, with one German magazine, "Der Spiegel," declaring that "The year 2020 will be known [...] as the year when machines began to outstrip us in research." Join me as we explore the background behind this transformative development and assess the magnitude of machine learning's impact on science, with a particular focus on structural biology. In 2021, Google published the methodology and source code for AlphaFold and within days, scientists adapted the code to allow virtually everyone to predict their own protein structures without prior knowledge. Now, two years after its public release, AlphaFold has established itself as an essential tool in structural biology. Yet, with time, we've also gained a deeper insight into its limitations. In this talk, I would like to delve into AlphaFold and similar machine learning techniques and explore their impact on science and structural biology. To truly appreciate their significance, we will first need to understand the role of protein structures and how they shape our daily lives. Additionally, we’ll have to examine how protein structures were traditionally solved prior to the advent of AlphaFold. We’ll then touch upon the concepts of protein evolution to better understand the biological basis behind this breakthrough, before we’ll look at the intricacies of the neural network itself and discuss the training data necessary to achieve its remarkable capabilities. Drawing from my experience as a practicing structural biologist, I will illustrate these points with real-life examples, showcasing instances where AlphaFold has succeeded and where it has encountered challenges. Lastly, we will peer into the future and speculate on the potential trajectory of this scientific journey and its potential to transform science and our approaches towards it. about this event: https://events.ccc.de/congress/2023/hub/event/alphafold_how_machine_learning_changed_structural_biology_forever_or_not/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12061-eng-deu-fra-AlphaFold_-_how_machine_learning_changed_structural_biology_forever_or_not_hd.mp4" length="637534208" type="video/mp4"/> <pubDate>Thu, 28 Dec 2023 14:45:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12061-eng-deu-fra-AlphaFold_-_how_machine_learning_changed_structural_biology_forever_or_not_hd.mp4?1703811989</guid> <dc:identifier>a3d8166c-e841-4071-ac0c-ddadaeeaef22</dc:identifier> <dc:date>2023-12-28T14:45:00+01:00</dc:date> <itunes:author>Jan Gebauer </itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 12061, 2023, Science</itunes:keywords> <itunes:subtitle>Getting first-hand insights into the impact of machine learning on life science</itunes:subtitle> <itunes:summary>In 2020, the scientific community was shaken when the results of a special contest for protein prediction, known as the Critical Assessment of Protein Structure Prediction (CASP), were revealed.

(37c3)</title> <link>https://media.ccc.de/v/37c3-11950-darf_s_noch_etwas_visionarer_sein</link> <description>Supereffiziente digitale Technik als Lösung aller Probleme oder doch lieber die selbstgebaute ressourcensparsame Low-Tech-Variante? Die Zukunftsvorstellungen, die den Einsatz digitaler Technik und ökologische Fragen zusammendenken, sind in der deutschen Diskurslandschaft nicht gerade üppig gesät. Im Vortrag werden die Ergebnisse einer Kurzstudie präsentiert, bei der wir die Zukunftsvorstellungen digital-ökologischer Transformation bei gesellschaftspolitischen Akteuren gesucht, analysiert und zu Visionskategorien zusammengefasst haben. Der Vortrag bietet einen Einblick in die Ergebnisse einer erstmaligen systematischen Untersuchung der im deutschsprachigen Diskurs präsenten Visionen zur digital-ökologischen Transformation und setzt diese in einer Landschaft an Vorstellungen von Transformation, Nachhaltigkeit und Technikgestaltung zueinander in Beziehung. Bei der Recherche wurden zivilgesellschaftliche, staatliche, wissenschaftliche und wirtschaftliche Akteure berücksichtigt. Das Ergebnis sind sechs verschiedene Typen an Visionskategorien: „Dematerialisierung", „Digital-ökologische Modernisierung", „Leitplanken einer zukunftsfähigen Digitalpolitik", „Digital-ökologischer TÜV", „Digitale Suffizienz" und „Low-Tech" bilden die Landschaft der Visionen digital-ökologischer Transformation im deutschsprachigen Raum. Die Vorstellung, dass digitale Technik durch Effizienzsteigerungen zu einer Entkopplung von Wirtschaftswachstum und Ressourcenverbrauch beiträgt, kann unter dem Begriff „Dematerialisierung” gefasst werden. „Digital-ökologische Modernisierung” bezeichnet einen eher technokratischen Ansatz, in dem die ökologischen Kosten der Digitalisierung durch Sparsamkeit, Recycling und vor allem den flächendeckenden Einsatz von erneuerbaren Energien zu bewältigen sind. Vertreter\*innen des Visionstyps „Leitplanken einer zukunftsfähigen Digitalpolitik” geben statt einer scharf formulierten Vision eher Leitplanken für die zukünftige Gestaltung der Digitalisierung im Rahmen ökologischer Grenzen vor. Die Kategorie „Digital-ökologischer TÜV” beschreibt Ansätze, die eine Bewertung des Verhältnisses von Ökologie und digitaler Technik von einer fortlaufenden Überprüfung des Einsatzes digitaler Technik abhängig machen. Bei „Digitaler Suffizienz” wird das Konzept der Suffizienz auf den Bereich Digitalisierung übertragen und orientiert sich an dem Motto „so viel Digitalisierung wie nötig, so wenig wie möglich“. Zuletzt kann die Idee der Abkehr vom linearen Fortschrittsdenken und von damit einhergehenden ressourcenintensiven High-Tech-Infrastrukturen als „Low-Tech”-Vision bezeichnet werden. Im Vortrag wird das Verhältnis der einzelnen Kategorien zueinander anhand von verschiedenen Dimensionen, wie ihr zugrundeliegendes Transformationsverständnis oder die Radikalität der beschriebenen Veränderungen, dargestellt sowie deren politische Bedeutung reflektiert.

Im Vortrag werden die Ergebnisse einer Kurzstudie präsentiert, bei der wir die Zukunftsvorstellungen digital-ökologischer Transformation bei gesellschaftspolitischen Akteuren gesucht, analysiert und zu Visionskategorien zusammengefasst haben. Der Vortrag bietet einen Einblick in die Ergebnisse einer erstmaligen systematischen Untersuchung der im deutschsprachigen Diskurs präsenten Visionen zur digital-ökologischen Transformation und setzt diese in einer Landschaft an Vorstellungen von Transformation, Nachhaltigkeit und Technikgestaltung zueinander in Beziehung. Bei der Recherche wurden zivilgesellschaftliche, staatliche, wissenschaftliche und wirtschaftliche Akteure berücksichtigt. Das Ergebnis sind sechs verschiedene Typen an Visionskategorien: „Dematerialisierung", „Digital-ökologische Modernisierung", „Leitplanken einer zukunftsfähigen Digitalpolitik", „Digital-ökologischer TÜV", „Digitale Suffizienz" und „Low-Tech" bilden die Landschaft der Visionen digital-ökologischer Transformation im deutschsprachigen Raum. Die Vorstellung, dass digitale Technik durch Effizienzsteigerungen zu einer Entkopplung von Wirtschaftswachstum und Ressourcenverbrauch beiträgt, kann unter dem Begriff „Dematerialisierung” gefasst werden. „Digital-ökologische Modernisierung” bezeichnet einen eher technokratischen Ansatz, in dem die ökologischen Kosten der Digitalisierung durch Sparsamkeit, Recycling und vor allem den flächendeckenden Einsatz von erneuerbaren Energien zu bewältigen sind. Vertreter\*innen des Visionstyps „Leitplanken einer zukunftsfähigen Digitalpolitik” geben statt einer scharf formulierten Vision eher Leitplanken für die zukünftige Gestaltung der Digitalisierung im Rahmen ökologischer Grenzen vor. Die Kategorie „Digital-ökologischer TÜV” beschreibt Ansätze, die eine Bewertung des Verhältnisses von Ökologie und digitaler Technik von einer fortlaufenden Überprüfung des Einsatzes digitaler Technik abhängig machen. Bei „Digitaler Suffizienz” wird das Konzept der Suffizienz auf den Bereich Digitalisierung übertragen und orientiert sich an dem Motto „so viel Digitalisierung wie nötig, so wenig wie möglich“. Zuletzt kann die Idee der Abkehr vom linearen Fortschrittsdenken und von damit einhergehenden ressourcenintensiven High-Tech-Infrastrukturen als „Low-Tech”-Vision bezeichnet werden. Im Vortrag wird das Verhältnis der einzelnen Kategorien zueinander anhand von verschiedenen Dimensionen, wie ihr zugrundeliegendes Transformationsverständnis oder die Radikalität der beschriebenen Veränderungen, dargestellt sowie deren politische Bedeutung reflektiert.

As part of the Predator Files investigation, Amnesty International, in partnership with European Investigative Collaborations, uncovered and documented for the first time how the Intellexa Alliance, a European-based surveillance vendor, has supplied advance spyware and surveillance technology to governments around the world, and where it has then been used to target journalists, leading politicians, and European institutions.

With ANIMAL()CITY we draw inspiration from the ghostly presence of foxes that roam the city at night – which nowadays is a common appearance in urban environments – evoking echoes of a pre-industrial era while at the same time drawing people’s attention to a layer of the city that completely eludes their perception in everyday life. In these moments we witness animals and plants forming their own realm and the city itself having its own life, acting like an entity, a ghost at times. Encounters with wild animals in the city make the parallel layers of the landscape momentarily tangible and remind us that we are part of these ‘non-human’ networks as well. On a darker note: urban wildlife not only echoes pre-industrial times but also projects an idea of what our cities will look like when all the people have disappeared due to the consequences of the climate catastrophe. However, the city may also be read analogous to the internet. Animals, humans and plants seldomly interact within the city, and while we might notice traces or encounter their phantoms we seem to live in parallel worlds. Similarly, online we are divided by platforms into threads and channels, living in multi-layered structures haunted by uncanny bots and AI agents. We believe that AR sculptures highlight an ethereal quality of the digital; they appear to transcend from the realm of immateriality into the physical space – the so-called spatial internet that overlays our cities. AR layers possess a magical quality in that they exist as objects whose influence on our world is – on a first step – contingent to our acceptance and perception of them as physical objects. ANIMAL()CITY is an aesthetic inquiry of the artists’ views on how AR may intercept different layers of perception and realities or completely superimpose them. The exhibition presents a collection of animals that transcend their natural forms and assume various "non-natural" shapes; from fantastical mythical creatures to archetypical animal sculpture adhering to classical composition to the most basic 3D animal assets, taken from game engine templates. These AR-animals introduce elements of imagination to their representation, inviting viewers to explore their own interpretations and engage with the artworks on different levels. about this event: https://events.ccc.de/congress/2023/hub/event/animal_city/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12344-eng-deu-ANIMAL_CITY_hd.mp4" length="266338304" type="video/mp4"/> <pubDate>Fri, 29 Dec 2023 16:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12344-eng-deu-ANIMAL_CITY_hd.mp4?1703871722</guid> <dc:identifier>43685bb3-3d09-4811-ba98-893c8b2625d0</dc:identifier> <dc:date>2023-12-29T16:00:00+01:00</dc:date> <itunes:author>Eva Davidova, Sakrowski, Sembo</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 12344, 2023, Art & Beauty</itunes:keywords> <itunes:subtitle>Unleashed!</itunes:subtitle> <itunes:summary>Presentation/introduction to the ongoing 37C3 art exhibition groupshow with Joachim Blank, Eva Davidova, Meredith Drum, exonemo, Jonas Lund, Sahej Rahal, Ingeborg Wie by panke.gallery (Sakrowski).

As the backbone of internet communication, the TCP/IP stack is a prime target for cyber threats. This presentation will unravel the intricacies of fuzzing techniques applied to several TCP/IP stacks, shedding light on how these methodologies can uncover bugs, crashes and vulnerabilities. From the fundamentals of packet fuzzing to advanced mutation strategies, attendees will gain valuable insights into the proactive ways to fuzz a TCP/IP stack. Whether you're a seasoned cybersecurity professional or a curious enthusiast, this talk promises to be an enlightening journey into the heart of TCP/IP stack security and the crucial role of fuzzing in safeguarding our interconnected world. Our exploration begins with an honest appraisal of traditional fuzzing methodologies that have been applied to TCP/IP stacks before, like ISIC, revealing their inherent limitations, e.g., they can't reach beyond the TCP initial state. Recognizing the need for a more evolved approach, we take a different approach, where we leverage a full-blow active network connection for fuzzing. A key revelation in this journey is the deliberate decision to sidestep the arduous task of constructing a custom TCP/IP stack, a choice rooted in practical considerations. The reluctance to build a bespoke TCP/IP stack leads us to innovative strategies such as embedding hooks in the Linux kernel and tapping into userland TCP/IP stacks like PyTCP, Netstack (part of Google gVisor), and PicoTCP. PicoTCP takes center stage, offering a userland TCP/IP stack that becomes integral to our state fuzzing methodology. Attendees will gain a deeper understanding of its architecture, APIs, and documentation, appreciating its pivotal role in fortifying network security. As the presentation unfolds, we navigate through the development of a powerful fuzzer, a core element in our approach to identifying vulnerabilities within the TCP/IP stack. The intricacies of driving traffic through the system, simulating real-world scenarios, and leveraging reproducibility and diagnostics techniques are revealed. The discussion expands to showcase tangible results, including trophies obtained, bugs reported, and the eventual release of the project on GitHub. The session concludes with an engaging Q & A, encouraging participants to delve into the intricacies of TCP/IP stack fuzzing and its profound implications for network security. about this event: https://events.ccc.de/congress/2023/hub/event/fuzzing_the_tcp_ip_stack/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12235-eng-deu-fra-Fuzzing_the_TCP_IP_stack_hd.mp4" length="351272960" type="video/mp4"/> <pubDate>Fri, 29 Dec 2023 12:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12235-eng-deu-fra-Fuzzing_the_TCP_IP_stack_hd.mp4?1703860520</guid> <dc:identifier>45057d82-26a3-40c9-8b94-c8631a0026f0</dc:identifier> <dc:date>2023-12-29T12:00:00+01:00</dc:date> <itunes:author>Ilja van Sprundel</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 12235, 2023, Security</itunes:keywords> <itunes:subtitle>beyond the trivial</itunes:subtitle> <itunes:summary>In this talk, we delve into the captivating realm of TCP/IP stack fuzzing.

This talk introduces the algorithms used for placement and routing of digital integrated circuits. The talk does \*not\* cover: \* high-level circuit design (The art of creating meaningful circuits. Often done with languages like Verilog, VHDL, SpinalHDL, Chisel, Amaranth, etc ) \* logic synthesis (Converts the high-level description into a graph-like circuit description, called netlist) Place-and-route refers to the transformation of a graph-like circuit description (netlist) into a geometrical representation of the circuit (layout). The netlist is typically produced by logic synthesis. The netlist consists of many sub-circuits, so called "standard-cells" but also "macro cells". Standard-cells implement simple logic functions such as inverters, logical "and", "nand", "xor", and storage elements. The netlist may also import larger pre-compiled macro cells such as SRAM blocks. For a physical implementation of the circuit, the sub-circuits need to be placed on the chip surface and need to be connected (routed) using metal wires. Transforming the netlist into a layout typically requires the following input data: \* A netlist of the circuit, of course. \* A set of constraints: For example the desired clock frequency and area of the circuit. \* Design rules: A set of constraints required for successful fabrication. This typically involves geometrical constraints such as minimum width and spacing of metal wires. \* A standard-cell library: This is a set of building-blocks usually used to assemble the circuit. The library contains the geometrical layout of the standard-cells and also information about their timing behavior. Then the following steps convert the input data into a layout: \* IO-planning: Decide where to put the input and output pins of the circuit. \* Floor-planning: Decide how to geometrically arrange various parts of a larger system. \* Power distribution: Insert regular rows of metallic power-rails which supply the standard-cells with energy \* Global placement: Decide where to roughly place the standard-cells such that the wiring will short and possible \* Tie-cell insertion: Provide constant 0 and 1 signals, where needed. \* Clock-tree synthesis: Storage elements typically need a clock-signal. Often the clock signal needs to be distributed to a large number of storage elements. \* Detail placement: Do fine-tuning, such as snapping the standard-cells to a grid the signal propagation delay from the clock source to the storage elements should be more-or-less equally distributed. \* Optimizations to meet timing requirements: Some signals might be too slow or to fast. There's a variety of techniques to improve this, such as amplifying signals with buffers. \* Routing: The placed cells need to be connected with metal wires. \* Filler insertion: fill unused space for example with capacitors to stabilize the supply voltage \* Verification: Make sure all constraints are met. Otherwise, try to fix the circuit and repeat above steps in order to converge to a valid solution. This talk will focus on a widely used algorithm for global placement and introduces basic principles of routing algorithms. about this event: https://events.ccc.de/congress/2023/hub/event/place_route_on_silicon/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11820-eng-und-deu-Place_route_on_silicon_hd.mp4" length="387973120" type="video/mp4"/> <pubDate>Wed, 27 Dec 2023 11:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11820-eng-und-deu-Place_route_on_silicon_hd.mp4?1703853433</guid> <dc:identifier>b56502da-90cb-4ae1-b055-2a1d3de52cb2</dc:identifier> <dc:date>2023-12-27T11:00:00+01:00</dc:date> <itunes:author>Thomas</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 11820, 2023, Hardware & Making</itunes:keywords> <itunes:subtitle>A gentle introduction to place & route algorithms for digital integrated circuits</itunes:subtitle> <itunes:summary>After a brief introduction to digital circuits this talk will outline placement and routing algorithms used for creating digital integrated circuits.

Then the following steps convert the input data into a layout: \* IO-planning: Decide where to put the input and output pins of the circuit. \* Floor-planning: Decide how to geometrically arrange various parts of a larger system. \* Power distribution: Insert regular rows of metallic power-rails which supply the standard-cells with energy \* Global placement: Decide where to roughly place the standard-cells such that the wiring will short and possible \* Tie-cell insertion: Provide constant 0 and 1 signals, where needed. \* Clock-tree synthesis: Storage elements typically need a clock-signal. Often the clock signal needs to be distributed to a large number of storage elements. \* Detail placement: Do fine-tuning, such as snapping the standard-cells to a grid the signal propagation delay from the clock source to the storage elements should be more-or-less equally distributed. \* Optimizations to meet timing requirements: Some signals might be too slow or to fast. There's a variety of techniques to improve this, such as amplifying signals with buffers. \* Routing: The placed cells need to be connected with metal wires. \* Filler insertion: fill unused space for example with capacitors to stabilize the supply voltage \* Verification: Make sure all constraints are met. Otherwise, try to fix the circuit and repeat above steps in order to converge to a valid solution. This talk will focus on a widely used algorithm for global placement and introduces basic principles of routing algorithms. about this event: https://events.ccc.de/congress/2023/hub/event/place_route_on_silicon/ </itunes:summary> <itunes:duration>00:38:38</itunes:duration> </item> <item> <title>SMTP Smuggling – Spoofing E-Mails Worldwide (37c3)</title> <link>https://media.ccc.de/v/37c3-11782-smtp_smuggling_spoofing_e-mails_worldwide</link> <description>Introducing a novel technique for e-mail spoofing. SMTP, the Simple Mail Transfer Protocol, allows e-mailing since 1982. This easily makes it one of the oldest technologies amongst the Internet. However, even though it seems to have stood the test of time, there was still a trivial but novel exploitation technique just waiting to be discovered – SMTP smuggling! In this talk, we’ll explore how SMTP smuggling breaks the interpretation of the SMTP protocol in vulnerable server constellations worldwide, allowing some more than unwanted behavior. Sending e-mails as admin@microsoft.com to fortune 500 companies – while still passing SPF checks – will be the least of our problems! From identifying this novel technique to exploiting it in one of the most used e-mail services on the Internet, we’ll dive into all the little details this attack has to offer.

With a primary mirror aperture of 39m, it will be the largest optical telescope on earth. We will briefly introduce the history and mission of ESO and explain how a modern optical telescope works. The European Southern Observatory (ESO) is an intergovernmental organisation founded in 1962 and is based in Garching bei München. It develops, builds and operates ground-based telescopes to enable astronomical research in the southern hemisphere and to foster cooperation in the international astronomical community. In 2012 the ESO Council approved the Extremely Large Telescope (ELT) programme and its construction is scheduled for completion in 2028. The 39m primary mirror will make the ELT the largest optical telescope at that time. It will be located on the top of Cerro Armazones, a ~3000m high mountain in the Atacama desert in Chile. This site provides ideal optical conditions, but also comes with logistical and engineering challenges. We will walk you through the telescope and along the optical path to the instruments and explain some of the technologies involved to push the boundaries of ground-based optical astronomy. about this event: https://events.ccc.de/congress/2023/hub/event/the_extremely_large_telescope_elt/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12020-eng-deu-fra-The_Extremely_Large_Telescope_ELT_hd.mp4" length="383778816" type="video/mp4"/> <pubDate>Wed, 27 Dec 2023 22:05:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12020-eng-deu-fra-The_Extremely_Large_Telescope_ELT_hd.mp4?1703729386</guid> <dc:identifier>54e92649-de11-40d9-99b0-526fd4572107</dc:identifier> <dc:date>2023-12-27T22:05:00+01:00</dc:date> <itunes:author>lk, panic</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 12020, 2023, Science</itunes:keywords> <itunes:subtitle>Building the biggest optical telescope on earth</itunes:subtitle> <itunes:summary>The Extremely Large Telescope (ELT) is currently under construction in the Atacama desert in northern Chile by the European Southern Observatory (ESO).

We'll present insights on the theoretical advantages of quantum algorithms, improvements in factoring large numbers, and the impacts of post-quantum crypto attacks. While the hype around quantum technologies is growing, the estimates in the resources needed to run a quantum algorithm and the current number of qubits pose caution in the enthusiasm. The limitations in terms of available qubits, error rates, and scalability are critical factors that need to be considered when assessing the real-world applicability of quantum computing. We will start with a fundamental introduction to quantum computing to ensure that the audience has a solid grasp of this model of computation, but without discussing the technicalities of quantum physics. Taking a "software development" perspective, we introduce the problem of estimating the resources needed to perform a quantum computation. Then, we will shift our focus to the two facets of our investigation: applications for offence and defence. Quantum machine learning for defence: We will explore the application of quantum machine learning algorithms in network intrusion detection. Quantum machine learning holds the potential for improving cybersecurity defences by leveraging quantum algorithms - exponentially faster than classical algorithm on their asymptotic complexity. We will introduce a framework for estimating the advantages of quantum algorithms in terms of query complexity, and report the findings of our experiments. Our findings will be based on practical experiments using benchmark datasets in cybersecurity, offering insights into the potential effectiveness of quantum approaches in this domain. Quantum attacks on cryptography for offence: Shifting our attention to the offensive side, we will investigate the potential impact of quantum attacks on cryptography. We will report some advancements in the number of qubits required to break RSA2048 cryptography and attacks on ECC256. Furthermore, we will delve into the complexities of post-quantum cryptography attacks. Our ongoing research at CQT (Centre for Quantum Technologies of Singapore) involves measuring the depth and size of quantum circuits, including the number of Toffoli gates and Toffoli-depth. We will also account for the qubit number and size of the QRAM query (quantum random access memory), providing a comprehensive assessment of the quantum attack landscape. Ultimately, we will draw conclusions based on our research and analysis. While there is limited evidence suggesting that quantum computing will have a drastic impact on cybersecurity through machine learning or attacks on post-quantum cryptography, there are substantial reasons to believe that quantum computers, once they reach sufficient scale and capacity, will pose a significant threat to RSA2048 and ECC256.

The Speaker is a member of the Demoscene since the 1980ies and gives insights how it is now and how it was back in the days and how you can participate! The demoscene is an underground computer art culture. The term demoscene comes from the word demo, short for demonstration. In the context of the demoscene the word demo means a realtime audiovisual application which is demonstrating the capabilities of the machine it runs on. Demosceners ("sceners") are what we call the folks with too much free time that abuse their computer skills to create releases under the demoscene. Demosceners often use nicknames ("nicks" or "handles") to identify themselves. They also tend to hang out in so-called demogroups. Some demosceners are active members of multiple demogroups, with or without using the same nickname. Let's get one thing clear: the demoscene has no commercial purpose. The only thing you'll get out of the demoscene, and this only comes after investing a significant amount of your free time into it, is a few useful soft skills and a large community of computer nerd friends. Demoscene releases are meant to show the limits of the machines, the technical skills and artistic sensibility of the makers. There are no rules to what kind of release you can make on the demoscene. Some demos are made as technical benchmarks, others as conceptual art, most are done just for fun. It is entirely up to you to explore what you like doing and share it with other demosceners. Demoscene releases can be divided into certain categories: Track, an audio piece, can be in an executable format, in a tracker module format or in a pre-rendered wav/mp3 format Graphics entry, drawn or rendered images with fixed resolutions and/or a restricted color palette Demo, an audiovisual real-time executable demonstration for a certain platform Intro, typically a demo with file size limitation all packed into a single executable file that includes all the assets (popular size formats are 256bytes, 512bytes, 1kb, 4kb, 8kb, 64kb) Animation, rendered graphics videos Demopack, a collection of demos in a single disk Musicdisk, a collection of demoscene tracks with an executable player interface Diskmag, a collection of texts about the demoscene with an executable graphics interface Wild entry, everything else (including live performances, videos of demos on uncommon platforms, videos about demomaking, etc) Releases typically occur at demoparties, gathering events for demosceners. about this event: https://events.ccc.de/congress/2023/hub/event/demoscene_now_and_then/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11846-eng-deu-Demoscene_now_and_then_hd.mp4" length="898629632" type="video/mp4"/> <pubDate>Thu, 28 Dec 2023 20:15:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11846-eng-deu-Demoscene_now_and_then_hd.mp4?1703801506</guid> <dc:identifier>3794b61d-8f56-4e0c-8895-8c674c1d6570</dc:identifier> <dc:date>2023-12-28T20:15:00+01:00</dc:date> <itunes:author>LordSpreadpointAmiga</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 11846, 2023, Art & Beauty</itunes:keywords> <itunes:subtitle>The demoscene is an underground computer art culture.</itunes:subtitle> <itunes:summary>The demoscene is an underground computer art culture.

While one might think "wildness" implies the absence of humans, in the age of the anthropocene and rapid climate change, the opposite is the case. It requires the development of an extensive, more-than-human-infrastructure. Our talk is based on artistic research into the ongoing rewilding project of the Northern bald ibis (Waldrapp), a large migratory bird, that has become extinct north of the alps in 1621 and are being released into the wild since 2013. The output of this research was rendered into a website which serves as a departure point of our talk. We outline the heterogeneous elements that make up the infrastructure of the rewilding project and what kind of situations are being produced therein. The graph of "the infrastructure of a migratoy bird" shows relationships between social, technological, informational, and ecological elements which make up the anthropogenic ecosystem in which the bird is becoming wild again. The objective was to visualise and comprehend the intricate network of data, energy resources, and dependencies deeply enmeshed within the project's framework. We will also focus on the types of data being produced and to what extent "acting" within this framework is informed to observation of movement data. One can trace the flow of information, observe how data is generated, processed and ultimately mediated. As a migratory bird that travels between 1600 and 4600km per year (from summer to winter habitats and back) this project could not be realized without intensive use of technology. This falls into two categories: assisted migration and location/movement tracking. As a social species, the birds have an instinct to migrate, but the concrete migration routes and destinations are socially learned. With the extinction, this social knowledge became extinct as well. This is a challenge and an opportunity for the project. On the one hand, the birds need to be trained the unnatural behaviour of following a light airplane, on the other hand, humans can guide them to specific areas where socio-environmental conditions are suitable for habitation. Currently, close to 85% of the more than 200 surviving rewilded birds are wearing a GPS/GSM tracker that enables near real-time monitoring of locations and movements. This data is used for monitoring the birds for signs of distress (injury, problems along the route, death etc), and for feeding an app (Animaltracker) that allows the interested public to track the birds and, to a limited degree, for behavioural research. From this, a different notion of wilderness emerges. Here it denotes not the separation from human culture, but a degree of freedom and autonomy in making decisions. Technology, the real-time tracking and social media coverage, serves as a way to increase the autonomy of the bird, supporting them to survive outside captivity, yet within densely populated, deeply cultured environments. Technology's main purpose here is not surveillance but care, both directly by enabling biologists to help struggling animals in the wild, but also indirectly, by supporting a deeper, affective relationship of the population towards wild animals which are no longer anonymous, but known by name, each with its distinct history and personal character. about this event: https://events.ccc.de/congress/2023/hub/event/infrastructure_of_a_migratory_bird/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12068-eng-deu-fra-Infrastructure_of_a_migratory_bird_hd.mp4" length="348127232" type="video/mp4"/> <pubDate>Thu, 28 Dec 2023 11:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12068-eng-deu-fra-Infrastructure_of_a_migratory_bird_hd.mp4?1703773366</guid> <dc:identifier>32189fea-f720-4c7d-b32b-f599954d94a8</dc:identifier> <dc:date>2023-12-28T11:00:00+01:00</dc:date> <itunes:author>Gordan Savičić, Felix Stalder</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 12068, 2023, Art & Beauty</itunes:keywords> <itunes:subtitle>Technology and autonomy in more-than-human networks</itunes:subtitle> <itunes:summary>What does it take to create a "wild animal"?

However, changes to hardware platforms in recent years such as the Intel ME, vendor-supplied binary blobs and vendor-signed firmware images have repeatedly set back efforts to create open source firmware for the computers we use. The release of Power servers with 99% open source firmware excited many who had been searching for a computer they could trust, but one proprietary firmware blob remained: that of the Ethernet controller. This is the story of how that blob was reverse engineered and replaced with an open source replacement, delivering the first machine with desktop-class performance and 100% open source firmware in many years. This talk is about how I reverse engineered the final remaining firmware blob on the Talos II/Blackbird POWER9 systems, enabling it to be replaced with an open source replacement, in an intensive reverse engineering effort that spanned several years. The talk will begin by introducing the open source firmware movement and its practical and ethical motivations, and note the obstacles to delivering fully open source firmware for contemporary x86 and other platforms and explaining the motive behind the project, before moving onto a more technical discussion of the adventure of firmware reverse engineering and the obstacles encountered. Subjects I intend to cover include: how the original proprietary firmware was reverse engineered from scratch with only limited knowledge of device internals; the long history of Broadcom NIC architecture and its evolution over time; the tools that had to be developed to enable the device probing, testing and reversing process; the story of a horrifying but necessary detour into reversing x86 real mode code and the novel methodology used to aid reversing; how modern NICs allow BMCs in servers to share network ports with the host, and the security hazards this creates; and how fully open source firmware was created legally using a clean room process. This talk will be accessible to audiences unfamiliar with POWER9 or the open source firmware community, but is also intended to cover some new ground and be of interest to those familiar with the project. The talk will mainly be of interest to those interested in open source firmware and issues such as owner control and the security and auditability issues caused by proprietary firmware, and to those interested in reverse engineering. about this event: https://events.ccc.de/congress/2023/hub/event/adventures_in_reverse_engineering_broadcom_nic_firmware/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11781-eng-deu-fra-Adventures_in_Reverse_Engineering_Broadcom_NIC_Firmware_hd.mp4" length="486539264" type="video/mp4"/> <pubDate>Wed, 27 Dec 2023 16:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11781-eng-deu-fra-Adventures_in_Reverse_Engineering_Broadcom_NIC_Firmware_hd.mp4?1703727534</guid> <dc:identifier>59a1c108-e367-4d71-bc50-7073cb8025e6</dc:identifier> <dc:date>2023-12-27T16:00:00+01:00</dc:date> <itunes:author>Hugo Landau</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 11781, 2023, Hardware & Making</itunes:keywords> <itunes:subtitle>Unlocking a system with 100% open source firmware</itunes:subtitle> <itunes:summary>In an era where vendors increasingly seek to use proprietary software in the devices around us to exert control over their users, the desire for open source software has expanded to the firmware that allows our machines to function, and platforms which individuals can trust and control have never been more important.

We present a proof of concept using AFL++ and QEMU to find command and SQL-injections, going beyond the classic fuzzing for memory corruption. We also present a scalable approach to fuzzing binary-only code with LibAFL and QEMU, showcasing how to build a custom fuzzer to test Android libraries without using a phone. In this talk, the maintainers of the AFLplusplus organization present the QEMU-based instrumentation engines developed as part of AFL++ and LibAFL to fuzz advanced binary-only targets. We discuss our extensions to QEMU, the well-known emulator, to allow high-performance, cross-architecture fuzzing and target instrumentation. Finally, we demo a proof of concept using AFL++ to find injection vulnerabilities in the binaries, going beyond the typical fuzzing for memory corruptions. We then present LibAFL QEMU, a library that offers convenient APIs to hook the target using Rust. Unlike other public fuzzers, tools built with LibAFL can scale over cores and machines to find vulnerabilities faster and at a large scale. We also showcase how we built a custom fuzzer for a binary-only Android library using this new emulator API for fuzzing that scales to 96 cores almost linearly, reaching a whopping number of executions per second! about this event: https://events.ccc.de/congress/2023/hub/event/fuzz_everything_everywhere_all_at_once/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12102-eng-deu-Fuzz_Everything_Everywhere_All_at_Once_hd.mp4" length="317718528" type="video/mp4"/> <pubDate>Thu, 28 Dec 2023 13:50:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12102-eng-deu-Fuzz_Everything_Everywhere_All_at_Once_hd.mp4?1703782292</guid> <dc:identifier>847c9f2d-8e3d-4c68-8c82-3435fae34dd0</dc:identifier> <dc:date>2023-12-28T13:50:00+01:00</dc:date> <itunes:author>domenukk, van Hauser, Dongjia Zhang, andreafioraldi, Addison Crump</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 12102, 2023, Security</itunes:keywords> <itunes:subtitle>Advanced QEMU-based fuzzing</itunes:subtitle> <itunes:summary>The maintainers of the AFLplusplus open-source project show crazy new ways to (ab)use QEMU to explore difficult, binary-only targets through fuzzing.

Das moderne Völkerrecht verbietet die Drohung oder den Einsatz militärischer Gewalt. Eine Ausnahme davon ist das Recht auf Selbstverteidigung im Falle eines bewaffneten Angriffes.

This talk will shed light on how these satellite services work, how they are integrated into existing fall and crash detection, present the security measures employed to safeguard resource access and privacy, and explore how this communication is embedded within the operating system. With the release of the iPhone 14, users can reach out to emergency services by sending an SOS message via a satellite link directly from their phone. This use of the GlobalStar network facilitates two-way communication with emergency responders through the Messages app. Users can easily send text messages and respond to queries. This communication channel, due to its sensitive nature, demands robust security and authentication. It is imperative for Apple to ensure that the system is foolproof, negating the possibility of dispatching emergency responders to incorrect locations or individuals. Equally significant is the protection of the privacy of those in need, including their location and the nature of their emergency. In our talk, we demonstrate how a rooted iPhone without satellite capabilities can be tricked into thinking that it can communicate with the satellite network. This technique allows us to trigger various emergency situations without actually contacting emergency services. On the rooted iPhone, we can then inspect the transport security and key derivation while these features are being used. We will present various insights into the proprietary satellite communication protocol based on this analysis. Moreover, Apple's satellite features allow users to share their location in Find My with up to ten friends via a satellite link. This capability serves as a convenient tool for staying connected with friends and family while venturing off the beaten path. We’ll take a look into how this new Find My extension is implemented. about this event: https://events.ccc.de/congress/2023/hub/event/bifrost_apple_s_rainbow_bridge_for_satellite_communication/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11948-eng-deu-fra-Bifroest_Apples_Rainbow_Bridge_for_Satellite_Communication_hd.mp4" length="275775488" type="video/mp4"/> <pubDate>Wed, 27 Dec 2023 20:15:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11948-eng-deu-fra-Bifroest_Apples_Rainbow_Bridge_for_Satellite_Communication_hd.mp4?1703728876</guid> <dc:identifier>e9ecf88b-5dde-4801-b9ce-3b62ac06b899</dc:identifier> <dc:date>2023-12-27T20:15:00+01:00</dc:date> <itunes:author>Alexander Heinrich, jiska</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 11948, 2023, Security</itunes:keywords> <itunes:summary>Apple's cutting-edge emergency SOS and location sharing services provide crucial communication alternatives when no cellular network is available.

We’ll take a look into how this new Find My extension is implemented. about this event: https://events.ccc.de/congress/2023/hub/event/bifrost_apple_s_rainbow_bridge_for_satellite_communication/ </itunes:summary> <itunes:duration>00:40:55</itunes:duration> </item> <item> <title>Rust Binary Analysis, Feature by Feature (37c3)</title> <link>https://media.ccc.de/v/37c3-11684-rust_binary_analysis_feature_by_feature</link> <description>A walkthrough of the assembly code idioms the Rust compiler uses to implement the language’s core features (as they appear in Klabnik’s and Nichols’ “The Rust Programming Language”) - starting with simple match expressions and all the way to monomorphized functions and iterator chains. You attempt to analyze a binary file compiled in the Rust programming language. You open the file in your favorite disassembler. Twenty minutes later you wish you had never been born. You’ve trained yourself to think like g++ and msvc: Here’s a loop, there’s a vtable, that’s a global variable, a library function, an exception. Now you need to think like the Rust compiler. Maybe you’ve heard about “sum types” and “generics” and “iterators”, maybe you haven’t, and in both cases you are going to have an exceptionally bad time. This talk will get you familiar with the assembly code idioms the Rust compiler uses to implement the language’s core features (as they appear in Klabnik’s and Nichols’ “The Rust Programming Language”), and more generally, the frame of mind required for reverse-engineering such programs. How is an Option<T> represented using the same amount of memory as a plain T? How do monomorphized generic functions complicate RE work? What's the right approach to untangle many-layered, unintuitive iterator chains? We will tackle these questions and many more. Includes a publicly available lab setup with several sample programs that showcase core Rust features as compiled to assembly. about this event: https://events.ccc.de/congress/2023/hub/event/rust_binary_analysis_feature_by_feature/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11684-eng-deu-Rust_Binary_Analysis_Feature_by_Feature_hd.mp4" length="342884352" type="video/mp4"/> <pubDate>Thu, 28 Dec 2023 17:15:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11684-eng-deu-Rust_Binary_Analysis_Feature_by_Feature_hd.mp4?1703802282</guid> <dc:identifier>6123fb8c-75dd-48fa-810f-f7dc3cdb73a4</dc:identifier> <dc:date>2023-12-28T17:15:00+01:00</dc:date> <itunes:author>Ben H</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 11684, 2023, Security</itunes:keywords> <itunes:summary>A walkthrough of the assembly code idioms the Rust compiler uses to implement the language’s core features (as they appear in Klabnik’s and Nichols’ “The Rust Programming Language”) - starting with simple match expressions and all the way to monomorphized functions and iterator chains.

This is truly a multi-stakeholder landscape and, through a continuous collective work, we have identified many core issues to be addressed. The fight against gender-based violence, the destigmatization of sex work, the accountability of big tech, the empowerment of CSOs and much more are all crucial aspects of our initiatives. We are confident that with a truly holistic approach we will be able to foster positive change.

But in the past year it has been specially tough in France. This talk is about shedding light on the many situations where the French State used surveillance to increase repression, mainly against activists, during the last months. Not to despair of this, but willing to provide a sincere overview to the rest of the world, La Quadrature du Net proposes to depict this situation as a satirical tale, with its own characters, plots and suspense. We want to show the political tension going on right now in France and how the checks and balances are lacking to stop this headlong rush to a surveillance state. Looking back to France in 2023, what do we see? Implementation of new technologies such as drones, DNA marking or new generation of spywares. Also, an intensification of political surveillance, either by law enforcement deploying disproportionate means of investigations towards environmental activists or intelligence services using cameras or GPS beacons to spy on places or people that they find too radical. It was also the year of the “8 December” case, a judicial case where among other things, encrypted communications of the prosecuted persons were considered as signs of "clandestinity" that reveal criminal intentions. On top of this, we also had to deal with the legalization of biometric surveillance for the Olympics and massive censorship of social networks when riots erupted in suburbs against police violence. This talk is about showing the reality of the situation at stake right now in France, and how it could influence the rest of Europe. At the end, we hope to raise awareness in the international community and start thinking about how, together, we can put pressure on a country who uses its old reputation to pretend to be respectful of human rights. about this event: https://events.ccc.de/congress/2023/hub/event/a_year_of_surveillance_in_france_a_short_satirical_tale_by_la_quadrature_du_net/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12309-eng-deu-fra-A_year_of_surveillance_in_France_a_short_satirical_tale_by_La_Quadrature_du_Net_hd.mp4" length="514850816" type="video/mp4"/> <pubDate>Thu, 28 Dec 2023 12:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12309-eng-deu-fra-A_year_of_surveillance_in_France_a_short_satirical_tale_by_La_Quadrature_du_Net_hd.mp4?1703781372</guid> <dc:identifier>7cde08a9-def1-4788-8e3e-b799e7b42556</dc:identifier> <dc:date>2023-12-28T12:00:00+01:00</dc:date> <itunes:author>Noémie, Marne and Nono</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 12309, 2023, Ethics, Politics & Society</itunes:keywords> <itunes:subtitle>From the so-called Country of human rights to a surveillance State</itunes:subtitle> <itunes:summary>Fighting against surveillance has never been easy.

This talk will tell the story of a series of Polish EMUs (Electric Multiple Unit) that all refused to move a few days after arriving at an “unauthorized” service company. We'll go over how a train control system actually works, how we reverse-engineered one and what sort of magical “security” systems we actually found inside of it.

This talk will tell the story of a series of Polish EMUs (Electric Multiple Unit) that all refused to move a few days after arriving at an “unauthorized” service company.

However with the iPhone 15, all of those tools became basically useless: USB-C is here, and with that we need new hardware and software tooling. This talk gives you a brief history of iPhone hardware hacking through the Lightning port, and then looks at the new iPhone 15, and how - using vendor defined messages, modifying existing tooling like the Central Scrutinizer, and a bit of hardware hacking - we managed to get access to the (unfortunately locked on production devices) JTAG interface exposed on the USB-C port on the new iPhone 15. And how you can do it using open-source tooling too. The iPhone's Lightning connector was a proprietary beast with a lot of hidden features: By sending custom SDQ commands there, it was possible to get it to expose hardware debugging features such as JTAG and UART. For a long time, this was only easily possible using either gray and black-market cables such as the Kanzi-Cable, or proprietary tools such as the Bonobo Cable. Last year, we released an open-source tool to get access to the iPhone debugging features called the Tamarin Cable - finally allowing anyone to get JTAG and UART on the iPhone for just a couple of $ in parts. But then the iPhone 15 came along, and with that USB-C: All previous hardware and software tooling basically became useless, but that did not stop us from trying: We knew from the Apple Silicon macs and the work of t8012-team and the AsahiLinux project that Apple uses USB-C's VDM feature - Vendor Defined Messages - to allow access to features such as the UART console, and so chances were high that we could use something similar to get access to the hardware debugging features on the iPhone 15. So we pre-ordered the iPhone 15, a couple of PCBs, a case of Club Mate and got started: And less than 48 hours after the launch we got JTAG working on the iPhone 15. In this talk we will start by looking at the history of iPhone and Lightning hardware hacking, and then look at how USB-C is used for debugging on Apple Silicon devices, and what we had to do to get JTAG on the iPhone 15. We will also use this talk to release the new version of the open-source Tamarin Cable firmware: Tamarin-C. A fully integrated, open-source debugging probe for the iPhone 15 and other Apple Silicon devices. Tamarin-C is also able to give access to a DFU mode that you can't access without sending VDMs. Note: This talk will not contain any 0days or previously unknown vulnerabilities. Production iPhones are locked, and so while we get access to some of the device's busses we can't for example access the CPU core. This talk is about building tooling for future work. about this event: https://events.ccc.de/congress/2023/hub/event/apple_s_iphone_15_under_the_c/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12074-eng-deu-fra-Apples_iPhone_15_Under_the_C_hd.mp4" length="294649856" type="video/mp4"/> <pubDate>Wed, 27 Dec 2023 12:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12074-eng-deu-fra-Apples_iPhone_15_Under_the_C_hd.mp4?1703767412</guid> <dc:identifier>a06319d5-f4a6-4efa-8255-dff6317e9632</dc:identifier> <dc:date>2023-12-27T12:00:00+01:00</dc:date> <itunes:author>stacksmashing</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 12074, 2023, Security</itunes:keywords> <itunes:subtitle>Hardware hacking tooling for the new iPhone generation</itunes:subtitle> <itunes:summary>Hardware hacking tooling for the new iPhone generation If you've followed the iPhone hacking scene you probably heard about cables such as the Kanzi Cable, Kong Cable, Bonobo Cable, and so on: Special cables that allow access to hardware debugging features on Lightning-based iPhones such as UART and JTAG.

Oder doch? Die scheinbar einfache Frage nach der Gesetzeskonformität von Zebrastreifen verursachte mysteriöses Schweigen in der öffentlichen Verwaltung der Stadt Luxemburg. Als Reaktion auf die Datenverweigerung schufen die Aktivist:innen des Zentrums für Urbane Gerechtigkeit eine Mischung aus Google Maps und Tinder, um die benötigten Daten selbst zu generieren. Dieser Vortrag beleuchtet das spannende Zusammenspiel von intransparenten Verwaltungen, der Eigeninitiative im Erstellen von Geodaten und dem juristischen Kampf um die Offenlegung von Informationen. Zudem wird aufgezeigt, welche Ressourcen ein solches Unterfangen erfordert, und wie es als lehrreiches Beispiel für zivilen Aktivismus und behördliche Transparenz dient. Die Geschichte begann mit einer einfachen Anfrage auf Twitter über die Gesetzeskonformität von Zebrastreifen in Luxemburg, die jedoch bei der Stadtverwaltung auf eine Mauer des Schweigens stieß. Als Reaktion darauf gründeten Aktivist:innen des Zentrums für Urbane Gerechtigkeit (ZUG) das Projekt "Safe Crossing", um die Einhaltung der Regularien für Zebrastreifen in Luxemburg-Stadt zu überprüfen. Mit einer Mischung aus Google Maps und Tinder entwickelten sie eine App, durch die die Nutzer:innen Luftbilder der Zebrastreifen analysieren und problematische Bereiche identifizieren konnten. Ihre Ergebnisse waren alarmierend: Etwa ein Drittel der insgesamt 1.787 analysierten Zebrastreifen entsprachen nicht den gesetzlichen Vorgaben, da Parkplätze die Sicht auf die Zebrastreifen blockierten und somit die Sicherheit der Fußgänger:innen gefährdeten. Trotz der Publikation ihrer Ergebnisse und der Diskussionen im Stadtrat bestritt die Stadtverwaltung die Ergebnisse und blieb bei ihrer eigenen, wesentlich niedrigeren Schätzung von nur 37 nicht regelkonformen Zebrastreifen. Die nachfolgenden Geschehnisse zeichneten ein Bild von intransparenten Verwaltungen und dem Kampf um die Offenlegung von Informationen. Trotz mehrerer offizieller Anfragen und einer Entscheidung der „Commission d’accès aux documents“ (CAD) zugunsten von ZUG weigerte sich die Stadt Luxemburg, die angeforderten Dokumente zu veröffentlichen. Der Fall eskalierte bis vor das Verwaltungsgericht, und ZUG lancierte eine Crowdfunding-Kampagne, um die anfallenden Rechtskosten zu decken. Der Vortrag wird die Herausforderungen und Erfolge des Projekts detailliert beleuchten, das Engagement für offene Daten und bürgerlichen Aktivismus hervorheben und auf die Bedeutung von Transparenz und Rechenschaftspflicht in der öffentlichen Verwaltung eingehen. Die Zuhörer:innen werden nicht nur Einblicke in die technischen und juristischen Aspekte des Projekts erhalten, sondern auch inspiriert werden, wie individuelle und kollektive Aktionen positive Veränderungen herbeiführen können, selbst wenn sie gegen bürokratische Mauern stoßen. about this event: https://events.ccc.de/congress/2023/hub/event/von_zebrastreifen_offenen_daten_und_verschlossenen_verwaltungen/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11983-deu-eng-Von_Zebrastreifen_offenen_Daten_und_verschlossenen_Verwaltungen_hd.mp4" length="236978176" type="video/mp4"/> <pubDate>Thu, 28 Dec 2023 11:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11983-deu-eng-Von_Zebrastreifen_offenen_Daten_und_verschlossenen_Verwaltungen_hd.mp4?1703773027</guid> <dc:identifier>e1a4a5df-9ef8-4364-b5c8-e8707ee83b8f</dc:identifier> <dc:date>2023-12-28T11:00:00+01:00</dc:date> <itunes:author>thorben, fedus</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 11983, 2023, Ethics, Politics & Society</itunes:keywords> <itunes:subtitle>Luxemburgs kreative Route zur Amtstransparenz</itunes:subtitle> <itunes:summary>Kein Zebrastreifen ist illegal.

In this talk, we demonstrate our voltage-glitching attack on Tesla Autopilot, enabling us root privileges on the system. Apart from building electric vehicles, Tesla has gained a reputation for their integrated computer platform comprising a feature-rich infotainment system, remote services through Tesla's Cloud and mobile app, and, most notably, an automated driving assistant. Enabled by a dedicated arm64-based system called Autopilot, Tesla offers different levels of "self-driving". The "full self-driving" (FSD) is provided to specific customers via in-car purchases and has been subject to public discourse. Despite using multiple cameras and Autopilot's machine learning (ML) models, accidents persist and shape FSD reporting. While the platform security of Autopilot's hardware protects the code and ML models from competitors, it also hinders third parties from accessing critical user data, e.g., onboard camera recordings and other sensor data, that could help facilitate crash investigations. This presentation shows how we rooted Tesla Autopilot using voltage glitching. The attack enables us to extract arbitrary code and user data from the system. Among other cryptographic keys, we extract a hardware-unique key used to authenticate Autopilot towards Tesla's "mothership". Overall, our talk will shed light on Autopilot's security architecture and gaps. Before delving into Autopilot, we successfully executed a Tesla Jailbreak of the AMD-based infotainment platform and presented our attack at BlackHat USA 2023. This achievement empowered custom modifications to the root file system and temporarily facilitated the activation of paid car features. about this event: https://events.ccc.de/congress/2023/hub/event/back_in_the_driver_s_seat_recovering_critical_data_from_tesla_autopilot_using_voltage_glitching/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12144-eng-deu-Back_in_the_Drivers_Seat_Recovering_Critical_Data_from_Tesla_Autopilot_Using_Voltage_Glitching_hd.mp4" length="263192576" type="video/mp4"/> <pubDate>Wed, 27 Dec 2023 13:50:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12144-eng-deu-Back_in_the_Drivers_Seat_Recovering_Critical_Data_from_Tesla_Autopilot_Using_Voltage_Glitching_hd.mp4?1703781973</guid> <dc:identifier>c51b416f-e656-4f43-a9dd-b9b3bedf3056</dc:identifier> <dc:date>2023-12-27T13:50:00+01:00</dc:date> <itunes:author>Niclas Kühnapfel, Christian Werling, Hans Niklas Jacob - hnj</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 12144, 2023, Security</itunes:keywords> <itunes:subtitle>Recovering Critical Data from Tesla Autopilot Using Voltage Glitching</itunes:subtitle> <itunes:summary>Tesla's driving assistant has been subject to public scrutiny for good and bad: As accidents with its "full self-driving" (FSD) technology keep making headlines, the code and data behind the onboard Autopilot system are well-protected by the car manufacturer.

Its hardware, software and protocols have many peculiarities since it is an old, distributed, fragmented and highly standardised system. This creates problems when trying to introduce state-of-the-art IT security, and then there is the mindset: "But we always have done it this way!" Although railways are one of the safest means of travel, they are not the most secure. What are railway engineers and IT experts fighting about? We will elaborate on the terms: Sicherheit, safety, security, and funktionale Sicherheit; and their implications. The first railways were closed systems where employees had visual contact with the equipment. With the increasing amount of software and network growth, IT security is becoming a major concern. On the other hand, railway systems are made from various components with real-time and dependability requirements, and proprietary protocols, resulting in some security via obscurity. The main difference from other systems is the high degree of standardisation necessary for obtaining a permit. Consequently, changes take time and effort, resulting in the longevity of protocols. This talk explains railway-specific protocols, such as GSM-R, RaSTA, and ETCS/ERMTS, their security model and known attacks. Nothing of this is new, but still, it is widely unknown. So, join the talk, have fun, and learn how to stop a train - which is much simpler than starting one. about this event: https://events.ccc.de/congress/2023/hub/event/why_railway_is_safe_but_not_secure/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11717-eng-deu-Why_Railway_Is_Safe_But_Not_Secure_hd.mp4" length="375390208" type="video/mp4"/> <pubDate>Thu, 28 Dec 2023 12:00:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11717-eng-deu-Why_Railway_Is_Safe_But_Not_Secure_hd.mp4?1703773613</guid> <dc:identifier>e91534ec-d9e8-46ba-a93e-bc5f2023d158</dc:identifier> <dc:date>2023-12-28T12:00:00+01:00</dc:date> <itunes:author>Katja Assaf</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 11717, 2023, Security</itunes:keywords> <itunes:subtitle>Security Of Railway Communication Protocols</itunes:subtitle> <itunes:summary>The railway communication network looks different from your standard corporate IT.

That’s exactly what happened to us! This led to the fixing of four zero-day vulnerabilities and discovering of a previously unknown and highly sophisticated spyware that had been around for years without anyone noticing.

Custom-Firmware, selfhosted Cloud-Ersatz und Tools zum Erzeugen von Inhalten ohne Herstellercloud. In unserem Vortrag über die Toniebox konzentrieren wir uns zunächst auf das Innenleben und die Funktionsweise dieses beliebten Audiogerätes für Kinder. Wir beginnen mit einer detaillierten Einführung in das Prinzip der Toniebox aus technischer Sicht und geben einen kurzen Überblick über die Hardwarekomponenten, insbesondere die verschiedenen Prozessorvarianten wie CC3200, CC3235 und ESP32. Der Übergang zu den Limitationen des Systems ist fließend: Wir diskutieren die künstlichen Beschränkungen durch den Hersteller, den Zwang zur Verwendung von Originalfiguren, die Inkompatibilität mit NFC-Tags von Drittanbietern und die hohen Kosten für bespielbare Figuren. Besonders kritisch sehen wir die vollständige Abhängigkeit von einer Hersteller-Cloud, die bei einem Ausfall des Anbieters das Gerät obsolet macht. Ein weiterer Fokus liegt auf dem ausgeprägten Datenhunger des Herstellers, der fast schon obsessiv das Nutzungsverhalten unserer Kinder aufzeichnet. Im Kern des Vortrags stellen wir die von uns entwickelten Open-Source-Alternativen vor. Mit der TeddyBench stellen wir einen Offline-Editor vor, mit dem Audiodaten für eigene NFC-Tags erstellt und verwaltet werden können. Die TeddyCloud bietet als selbstgehostete Lösung volle Kontrolle über die eigenen Daten, eine persönliche Audio-Bibliothek und die Möglichkeit, Nutzungsdaten über MQTT in den Home Assistant einzuspeisen, ohne die Funktionalität der Box einzuschränken. Außerdem stellen wir Custom Firmwares für CC3200 und ESP32 vor, die neue Einsatzmöglichkeiten eröffnen, und berichten über unsere Hardware-Modifikationen, die unter anderem Bluetooth-Audio ermöglichen und die Toniebox barrierefreier machen. about this event: https://events.ccc.de/congress/2023/hub/event/toniebox_reverse_engineering/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11993-deu-eng-Toniebox_Reverse_Engineering_hd.mp4" length="477102080" type="video/mp4"/> <pubDate>Wed, 27 Dec 2023 14:45:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11993-deu-eng-Toniebox_Reverse_Engineering_hd.mp4?1703711880</guid> <dc:identifier>b3163149-505e-497e-9c75-7cb233b59fcd</dc:identifier> <dc:date>2023-12-27T14:45:00+01:00</dc:date> <itunes:author>g3gg0, 0xbadbee, Moritz, Gambrius</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 11993, 2023, Hardware & Making</itunes:keywords> <itunes:subtitle>Eine Musikbox für Kinder, Maker und Hacker</itunes:subtitle> <itunes:summary>Ein Vortrag über den erfolgreichen Kinder-Audioplayer „Toniebox“ mit Content-Hosting in der Cloud, der nicht nur Einblicke in die (un-)heimliche Datensammlungspraxis bietet, sondern auch gleich passende Lösungen dazu.

Adding to our initial disclosure, this talk will present new details on our deanonymization attack and provide additional insights into background and new developments. In August 2023, we published the TETRA:BURST vulnerablities - the result of the first public in-depth security analysis of TETRA (Terrestrial Trunked Radio): a European standard for trunked radio globally used by government agencies, police, military, and critical infrastructure. Authentication and encryption within TETRA are handled by proprietary cryptographic cipher-suites, which had remained secret for over two decades through restrictive NDAs until our reverse-engineering and publication. TETRA:BURST consists of five vulnerabilities, two of which are critical, including the backdoored TEA1 cipher (crackable in minutes on commodity hardware by a passive adversary), a keystream recovery attack (which works regardless of the cipher employed), and a deanonymization attack with counter-intelligence implications. In this talk, we will discuss and demonstrate the TETRA:BURST vulnerabilities themselves and will - for the first time - disclose the details of the TA61 identity anonymization primitive and our Meet-in-the-Middle deanonymization attack against it. In addition, we will provide more background on how the TEA1 backdoor proliferated throughout Europe and provide attendees with an update on new developments since our initial disclosure, the future of TETRA, and the vast amount of TETRA hardening work that still needs to be done in critical infrastructure. about this event: https://events.ccc.de/congress/2023/hub/event/all_cops_are_broadcasting/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11761-eng-deu-All_cops_are_broadcasting_hd.mp4" length="602931200" type="video/mp4"/> <pubDate>Wed, 27 Dec 2023 17:15:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-11761-eng-deu-All_cops_are_broadcasting_hd.mp4?1703712550</guid> <dc:identifier>ff7f8d87-9319-41e4-857f-42c5c7124f4b</dc:identifier> <dc:date>2023-12-27T17:15:00+01:00</dc:date> <itunes:author>Jos Wetzels, Carlo Meijer, Wouter Bokslag</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 11761, 2023, Security</itunes:keywords> <itunes:subtitle>TETRA unlocked after decades in the shadows</itunes:subtitle> <itunes:summary>This talk will present details of the TETRA:BURST vulnerablities - the result of the first public in-depth security analysis of TETRA (Terrestrial Trunked Radio): a European standard for trunked radio globally used by government agencies, police, military, and critical infrastructure relying on secret cryptographic algorithms which we reverse-engineered and published in August 2023.

Das Thema stand im Ampel-Koalitionsvertrag, aber was es jetzt geben soll, ist ein Accountsperren-Gesetz, das eine Gefahr für die Anonymität im Netz sein könnte. Das Justizministerium möchte Digitale Gewalt gegen Unternehmen bestrafen ("Restaurantkritik"), aber wer weiterhin im Regen steht: Betroffene und Beratungsstellen. Was hat sich geändert, was nicht und warum müssen wir immer noch unsere Privatadressen ins Impressum schreiben – darum geht es in diesem Talk. Die Ampel hat in ihren Koalitionsvertrag geschrieben, dass es ein Digitale-Gewalt-Gesetz geben soll und das schien ein großer Schritt vorwärts. Als ich vor fünf Jahren beim 35C3 über Digitale Gewalt sprach, war das Thema kaum bekannt und seitdem hat sich viel getan. Dieser Talk gibt einen Überblick zum Stand der Dinge: Was ist seitdem passiert, was wird unter dem Begriff verstanden und was wissen wir inzwischen über das Ausmaß, neue und alte Formen digitaler Gewalt und den Umgang damit.

Das Thema stand im Ampel-Koalitionsvertrag, aber was es jetzt geben soll, ist ein Accountsperren-Gesetz, das eine Gefahr für die Anonymität im Netz sein könnte. Das Justizministerium möchte Digitale Gewalt gegen Unternehmen bestrafen ("Restaurantkritik"), aber wer weiterhin im Regen steht: Betroffene und Beratungsstellen. Was hat sich geändert, was nicht und warum müssen wir immer noch unsere Privatadressen ins Impressum schreiben – darum geht es in diesem Talk. Die Ampel hat in ihren Koalitionsvertrag geschrieben, dass es ein Digitale-Gewalt-Gesetz geben soll und das schien ein großer Schritt vorwärts. Als ich vor fünf Jahren beim 35C3 über Digitale Gewalt sprach, war das Thema kaum bekannt und seitdem hat sich viel getan. Dieser Talk gibt einen Überblick zum Stand der Dinge: Was ist seitdem passiert, was wird unter dem Begriff verstanden und was wissen wir inzwischen über das Ausmaß, neue und alte Formen digitaler Gewalt und den Umgang damit.

Discover how we are democratizing space by embracing open-source technologies, community collaboration, and a commitment to sustainability. The current state of the space ecosystem is characterized by its reliance on defense-oriented policies and outdated systems, hindering the true potential of space exploration. Despite the promise of Space 4.0, the reality is that space remains largely inaccessible to the public at large. Against this backdrop, a group of hackers and makers is revolutionizing the space industry. By promoting the hacker ethos of innovation, resourcefulness, and open-source principles, they are challenging the status quo and delivering creativity and accessibility into the space sector. Driven by the hackerspace movement and the broader community, we, Libre Space Foundation, are actively building our own satellites, space technologies, sharing knowledge and resources, and pushing the boundaries of space exploration. Our mission is to democratize space, making it available to everyone, regardless of background or resources. This emerging movement faces unique challenges, including working within a small, underfunded ecosystem, developing software and hardware, mapping out processes amidst complex space law and global politics, and ensuring long-term sustainability without relying on external funding. To overcome these challenges and harness the full potential of this movement, we propose a manifesto with four pillars: Open Source: All technologies developed for outer space shall be published and licensed using open source licenses. Open Data: All data related to and produced in outer space shall be freely accessed, used and built upon by anyone, anywhere, and shall be shared and managed according to the principles above. Open Development: All technologies for outer space shall be developed in a transparent, legible, documented, testable, modular, and efficient way. Open Governance: All technologies for outer space shall be governed in a participatory, collaborative, direct, and distributed way. By embracing these pillars, we can create a more open, inclusive, and sustainable space ecosystem that empowers individuals and communities to participate in the exploration of the cosmos. about this event: https://events.ccc.de/congress/2023/hub/event/how_to_hack_your_way_to_space/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12327-eng-deu-How_to_Hack_Your_Way_to_Space_hd.mp4" length="481296384" type="video/mp4"/> <pubDate>Wed, 27 Dec 2023 17:15:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12327-eng-deu-How_to_Hack_Your_Way_to_Space_hd.mp4?1703712206</guid> <dc:identifier>13794e21-cb3a-422a-91a8-32366acee6ee</dc:identifier> <dc:date>2023-12-27T17:15:00+01:00</dc:date> <itunes:author>Manthos Papamatthaiou, Alfredos (fredy) Damkalis</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 12327, 2023, Hardware & Making</itunes:keywords> <itunes:subtitle>Bringing the Hacker Mindset to the Space Ecosphere - The story behind the Libre Space Foundation (LSF)</itunes:subtitle> <itunes:summary>Embark on Libre Space Foundation's journey into the world of open-source space exploration, where a passionate community of hackers and makers is challenging the traditional defense-driven approach to spacefaring.

Euclid wurde am 1. Juli 2023 gestartet und beginnt bis Ende des Jahres seine auf 6 Jahre geplante wissenschaftliche Himmelsdurchmusterung. Euclid wird mit seinem Spiegel von 1,20 m Durchmesser und seinen zwei Kameras Bilder und Spektren von einem Drittel des gesamten Himmels aufnehmen. Das Ziel: mit der genauen Vermessung von insgesamt zwei Milliarden Galaxien der Natur von „Dunkler Materie" und „Dunkler Energie" im Universum auf den Grund zu gehen – die zwar zusammen 95 % der Gesamtenergie ausmachen, von denen wir aber nicht wissen, was sie sind und woraus sie bestehen. Euclid hat im November erste spektakuläre Bilder veröffentlicht. Ich werde die Mission vorstellen, die wissenschaftlichen Ziele, die Methoden und darauf eingehen, was in den 25 Jahren von Idee über Teleskop zu wissenschaftlicher Erkenntnis so alles zu erledigen war und ist. Die Astronomie weiß aktuell von 95 % der Energie und Masse im Universum nicht, woraus sie bestehen. Neben 5 % „normaler“ Materie (Sterne, Gas, die Erde, CCC-Kongressteilnehmer\*innen, …) gibt es mindestens fünfmal so viel so genannte dunkle Materie und darüberhinaus sind die restlichen 70 % das, was dunkle Energie genannt wird. Bei beidem wissen wir bislang nicht, woraus sie bestehen – wir kennen nur deren Wirkung! Galaxien rotieren anders, als sie es nur mit normaler Materie tun würden. Und das Universum expandiert – seit dem Urknall – aber die Expansionsgeschwindigkeit nimmt zu und nicht ab, wie von anziehender Materie zu erwarten wäre. Irgendwas drückt den Raum an sich auseinander. Euclid ist ein Teleskop, eine Mission und ein Konsortium aus mehreren tausend Menschen, von denen viele seit ca. 2008 an den Ideen zu dieser Mission arbeiten, viele hundert an der Planung und dem Bau zweier hoch empfindlicher Kameras mit insgesamt knapp 700 Millionen Pixel und jetzt ein- bis zweitausend Interessierten, welche die bald erwarteten wissenschaftlichen Bilder auswerten wollen. Ich möchte die Ziele erläutern, wie man aus der Vermessung der Form von Galaxien unsichtbare dunkle Materie im Vordergrund aufspürt („schwacher Gravitationslinseneffekt“) und warum es einen „kosmischen Längenmaßstab“ gibt, mit dem man die Ausdehnung des Universums über zehn Milliarden Jahre in der Vergangenheit vermessen kann. Schließlich möchte ich die ersten fünf Bilder zeigen, die von Euclid aufgenommen und von der ESA im November veröffentlicht wurden – und warum in denen so viel mehr drinsteckt, als man auf einem Computermonitor so sieht. about this event: https://events.ccc.de/congress/2023/hub/event/euclid_das_neue_weltraumteleskop/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12182-deu-eng-Euclid_-_das_neue_Weltraumteleskop_hd.mp4" length="313524224" type="video/mp4"/> <pubDate>Wed, 27 Dec 2023 21:10:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12182-deu-eng-Euclid_-_das_neue_Weltraumteleskop_hd.mp4?1703717752</guid> <dc:identifier>a9f690f3-e01a-4644-aa15-4276da6879ff</dc:identifier> <dc:date>2023-12-27T21:10:00+01:00</dc:date> <itunes:author>Knud Jahnke</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 12182, 2023, Science</itunes:keywords> <itunes:subtitle>Mit Milliarden leuchtenden Galaxien den dunklen Teil des Kosmos verstehen</itunes:subtitle> <itunes:summary>„Euclid" ist ein neues Weltraumteleskop der Europäischen Weltraumbehörde mit Beteiligungen eines Wissenschaftskonsortiums aus vierzehn europäischen Ländern, den USA, Kanada und Japan.

The talk will give a brief overview of the design research project, from the first prototypes to an empirical study and its publication, and provide insights into the underlying hardware and software. Being born blind or losing sight is a major challenge, as it impairs the ability to acquire information about surroundings, to manage everyday life independently and, consequently, to participate equally in social, public and economic life. Technical aids developed to assist VIPs with certain tasks work well in the laboratory but regularly fail in practice because they are bulky or user-unfriendly. As a result, the target group resorts to traditional tools or simply lives with the shortcomings. Given the rapid changes in technology and low cost of digital tools, I saw great potential in addressing this issue as an interaction design project. The result is an open-source Sensory Substitution device – the Unfolding Space Glove: it transmits the relative position and distance of nearby objects, detected by an on-board 3D camera, to the back of the hand in the form of vibratory stimuli. This allows the user to haptically explore the depth of the surrounding space and assists with navigation tasks such as object recognition and wayfinding. The prototype requires no external hardware, is highly portable, works in all lighting conditions, and provides continuous and immediate feedback – all while being visually unobtrusive. The basic premise of the proposed concept of Sensory Substitution is that the function of a missing or impaired human sensory modality can be replaced by stimulating another sensory modality using the missing information. This only works because the brain is plastic enough to learn to associate the new stimuli with the missing modality, as long as they share the same basic characteristics. There have been a number of projects looking at this, but so far very few practical implementations have been proposed, which in turn are used by a negligible number of people. While the technology used is sometimes highly sophisticated, design and usability often suffer. Taking into account the problems of existing devices and specifically addressing usability and interaction design requirements, the Unfolding Space Glove was designed and developed in a four-year interaction design research project. In 2021, the prototype was tested in an empirical study with 14 sighted and blind subjects, the results of which were published in a scientific, peer-reviewed paper in 2022. I would like to introduce you to the field of Sensory Substitution, share this project with you, show pitfalls, problems (for me coming from a non-IT background) and some technical details and ask for your feedback and input. I will have the device with me if you want to have a closer look at it after the talk.

(37c3)</title> <link>https://media.ccc.de/v/37c3-12004-please_identify_yourself</link> <description>Digital Identity Systems proliferate worldwide without any regard for their human rights impact or privacy concerns. Driven by governments and the crony capitalist solutionism peddled by the private sector, official statistics estimate that 80 % of the world’s population is condemned to use them by the end of this decade. These identification systems are a frontal attack on anonymity in the online world, might lead to completely new forms of tracking and discrimination and they are a gift to Google and other companies which are monitoring the behaviour of people on a large scale. In this talk we focus on how the recent EU reform played out, how the UN is becoming a central player in promoting their hasty adoption and which strategies civil society and hackers can deploy to fight back. After over two years of intense negotiations, the EU recently agreed to their Digital Identity Reform (eIDAS). In this talk we analyse the result, what safeguards we can realistically expect and how our online and offline interactions might change because of this new European Digital Identity Wallet. Other regions in the world are much further ahead in this issue and we will also try to learn from the experiences from India and Kenya. Both countries had unique strategies from civil society to fight back against the introduction of digital identity systems, focusing on interrogating their design, raising awareness, strategic litigation and civil disobedience post deployment . Lastly, this issue pops up in many countries and is actively promoted as "Digital Public Infrastructure" by global organisations like UNDP and the World Bank - often with little to know credence to privacy or local realities.

Driven by governments and the crony capitalist solutionism peddled by the private sector, official statistics estimate that 80 % of the world’s population is condemned to use them by the end of this decade. These identification systems are a frontal attack on anonymity in the online world, might lead to completely new forms of tracking and discrimination and they are a gift to Google and other companies which are monitoring the behaviour of people on a large scale. In this talk we focus on how the recent EU reform played out, how the UN is becoming a central player in promoting their hasty adoption and which strategies civil society and hackers can deploy to fight back. After over two years of intense negotiations, the EU recently agreed to their Digital Identity Reform (eIDAS). In this talk we analyse the result, what safeguards we can realistically expect and how our online and offline interactions might change because of this new European Digital Identity Wallet. Other regions in the world are much further ahead in this issue and we will also try to learn from the experiences from India and Kenya. Both countries had unique strategies from civil society to fight back against the introduction of digital identity systems, focusing on interrogating their design, raising awareness, strategic litigation and civil disobedience post deployment . Lastly, this issue pops up in many countries and is actively promoted as "Digital Public Infrastructure" by global organisations like UNDP and the World Bank - often with little to know credence to privacy or local realities. This global trend is very worrying due to the shiny veneer hiding their dark reality of exploitation by local and foreign actors. We will showcase strategies how local actors have resisted and shaped the introduction of these systems with a combination of technical, advocacy, and interdisciplinary ally building. Our goal is to provide knowledge about how exactly these systems work, who benefits from them and what strategies could be deployed against them. about this event: https://events.ccc.de/congress/2023/hub/event/please_identify_yourself/ </itunes:summary> <itunes:duration>00:45:41</itunes:duration> </item> <item> <title>Klimafreundliche Digitalisierung: Koalitionsvertrag vs. Wirklichkeit (37c3)</title> <link>https://media.ccc.de/v/37c3-12139-klimafreundliche_digitalisierung_koalitionsvertrag_vs_wirklichkeit</link> <description>Wie der Bund seine IT einkauft und betreibt, hat eine erhebliche Auswirkung auf das Klima. GroKo und Ampel-Regierung waren und sind daher groß im Ankündigen grüner IT: in digitalpolitischer Umweltagenda, Koalitionsvertrag, Digitalstrategie und Gigabitstrategie. Wie weit Anspruch und Wirklichkeit auseinanderklaffen, erfrage ich als Bundestagsabgeordnete regelmäßig mit Kleinen Anfragen und schriftlichen Fragen. Ich verspreche kleine Hoffnungsschimmer, aber auch Frustration, denn meine neueste Anfrage vom November 2023 deckt schonungslos auf, wie intransparent und wie wenig nachhaltig die IT des Bundes immer noch ist und wie die Ampel sich die Latte immer tiefer hängt und trotzdem nicht drüber kommt. Das Potenzial des Bundes als Großverbraucher (z. B. mit über 180 Rechenzentren), als Finanzierer (z. B. von über 400 KI-Projekten) und als Regulierer (z. B. beim Energieeffizienzgesetz oder beim Überbau von Glasfaser) ist aber riesig, auch das werde ich vermitteln und die Stellschrauben beschreiben, an denen man drehen könnte, um IT weniger klimaschädlich zu machen – auch außerhalb des Bundes. Der Bund kauft jährlich für 260 Mrd. € ein, auch für mehr als 1 Mrd. IT, er betreibt über 180 Rechenzentren, förderte in 2023 über 400 KI-Projekte, setzt selbst über 100 Mal KI-Systeme ein und hat noch aus vielen weiteren Gründen mit seiner IT eine erhebliche Klimawirkung. Wie die GroKo hat sich auch die Ampel auf die Fahnen geschrieben, die Digitalisierung klimafreundlicher zu machen, ganz allgemein – durch Regulierung für alle (z. B. im Energieeffizienzgesetz), aber auch in eigener Verantwortung, bei den eigenen Rechenzentren, Software oder IT-Dienstleistungen. Die Ankündigungen dazu sind wohltönend, z. B. im Koalitionsvertrag und in der Digitalstrategie. Bundesbehörden und Rechenzentren sollen klimafreundlich(er) werden, es soll mehr Transparenz geben, z. B. über ein Energieeffizienzregister für Rechenzentren, es wurde versprochen, dass Vergabeprozesse die Nachhaltigkeit berücksichtigen sollen, auch beim Einkauf von IT und IT-Dienstleistungen, z. B. durch standardmäßigen Einkauf von IT mit Blauem Engel – auch bei Software. Selbst der Ausbau der Gigabitinfrastruktur sollte nachhaltiger werden. Aber passiert das alles auch? Ich nutze meine parlamentarischen Rechte als Bundestagsabgeordnete der Opposition (DIE LINKE), um über schriftliche Fragen und Kleine Anfragen Fakten dazu öffentlich zu machen und die große Kluft zwischen Anspruch und Wirklichkeit zu zeigen. Dabei geht es einerseits um das Vorhandensein von Daten (you get what you measure!) – tatsächlich also um einen Mangel an Transparenz zur Baseline – und andererseits um die Daten selbst, also wie gut oder schlecht die Nachhaltigkeit jeweils ist. Einen Schwerpunkt lege ich dabei auf die Klimafreundlichkeit von Rechenzentren, aber auch zu anderen Themen gibt’s für Euch Fakten: zur Wiederverwendung von Hardware, zum Recht auf Reparatur und der (versprochenen!) Förderung von Reparatur-Initiativen, zur Berücksichtigung von Nachhaltigkeitsaspekten bei der Vergabe von Hunderten Millionen Euro Fördergelder für KI-Projekte, zu Websites, Software und mehr. Da ich seit mehreren Jahren zur Nachhaltigkeit der Bundes-IT Kleine Anfragen stelle und die Digitalpolitik der Bundesregierung aus dem Maschinenraum des Bundestages verfolge, kann ich auch die Entwicklung beschreiben und werde Euch zeigen, wie die Ampel-Regierung sich einfach die Latte immer niedriger hängt und vermutlich trotzdem kaum eines ihrer Nachhaltigkeitsziele erreichen wird. Beim 37C3 werde ich erstmalig die Ergebnisse meiner jüngsten Anfrage vom November 2023 öffentlich vorstellen.

These audio samples, in addition to recordings of wind from other missions served as as reference sources in order to characterize the acoustic processes Mars for the first time. It was discovered that: - The acoustic impedance of the martian atmosphere results in approximately 20 dB weaker sounds on Mars than on Earth (if produced by the same source.) - The acoustic attenuation range on Mars was discovered to be roughly between 20Hz to 20kHz. - On Mars low-pitched sounds travel at about 240 m/s (537 mph) while higher-pitched sounds move at 250 m/s (559 mph) due to the low atmospheric pressure 0.6 kPa (170 times lower than on Earth) and 97 percent CO2-dominated atmosphere (compared to 0.04 percent CO2 on Earth). The results were published by NASA in Journal Nature as to these findings. [https://www.nature.com/articles/s41586-022-04679-0] and on the Nasa website [https://mars.nasa.gov/mars2020/participate/sounds Referencing the paper published by NASA in Journal Nature as to these findings, analog astronaut and MDRS 286 crew artist Scott Beibin worked with master audio engineer John Knott to develop a software filter that could be used during Ptelepathetique concert performed during a two week immersive astronaut training in order to simulate the sounds of Mars. During the talk at 37C3 Beibin will discuss and demonstrate the comparison between the acoustic properties of the atmospheres of Earth and Mars via a demonstration of the software as well as musical Ptelepathetique performance. During the talk he will also present a short summary of the design patterns of the The Mars Desert Research Station which is used to train astronauts, researchers and students for offworld expeditions to the Red Planet. Additionally he will touch on the other aspects of his mission including 3D scanning of the surrounding geology as well as 3D printing of objects useful at the base using locally gathered and processed clay. This should be an out-of-this-world treat for the Space Cadet hackers and others who like making astronauts out of themselves. ++ Ptelepathetique is a musical project of inventor, engineer and artist Scott Beibin that focuses on the creation of instrumental cinematic psychoacoustic soundscapes designed to stimulate focus and creativity. Concerts usually happen outdoors in natural settings while using off-grid generated power while consisting of a mix of original musical composition as well as improvisation. Ptelepathetique is also the soundtrack for Beibin's projects The Groucho Fractal Show, AncientScan and the Mandelbot Ecotech Roadshow. ++ The Mars Desert Research Station (MDRS) is a Space analog facility in Utah that supports Earth-based research in pursuit of the technology, operations, and science required for human space exploration. The remotely isolated facility created by The Mars Society offers scientists, engineers and students rigorous training for human operations on Mars as is surrounded by a landscape that is an actual geologic Mars analog. about this event: https://events.ccc.de/congress/2023/hub/event/music_on_mars_a_musical_adventure_for_astronauts_and_the_space_cadets_who_love_them/ </description> <enclosure url="https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12268-eng-deu-Music_on_Mars_A_Musical_Adventure_for_Astronauts_and_the_Space_Cadets_Who_Love_Them_hd.mp4" length="499122176" type="video/mp4"/> <pubDate>Wed, 27 Dec 2023 21:10:00 +0100</pubDate> <guid isPermaLink="true">https://cdn.media.ccc.de/congress/2023/h264-hd/37c3-12268-eng-deu-Music_on_Mars_A_Musical_Adventure_for_Astronauts_and_the_Space_Cadets_Who_Love_Them_hd.mp4?1703717514</guid> <dc:identifier>99b87729-3aa6-442b-83d6-9b1eb06b7e81</dc:identifier> <dc:date>2023-12-27T21:10:00+01:00</dc:date> <itunes:author>Scott Beibin</itunes:author> <itunes:explicit>No</itunes:explicit> <itunes:keywords>37c3, 12268, 2023, Art & Beauty</itunes:keywords> <itunes:subtitle>A Musical Adventure for Astronauts and the Space Cadets Who Love Them.</itunes:subtitle> <itunes:summary>During Mission 286 in November 2023 at the Mars Desert Research Station (MDRS), Analog Astronaut and crew artist Scott Beibin performed several concerts of original live musical compositions during a two week immersive astronaut training. +++ The concerts were played through a custom audio filter based on data gathered by the NASA Mars Perseverance Rover and created to simulate the acoustic properties of Mars - designed by Beibin and master audio engineer, John Knott. +++ The live sets were performed in the MDRS Science Dome as well as during EVAs while navigating the desolate terrain in a simulation space suit - at sunset with the MDRS base and remote Mars-like Utah desert serving as a backdrop. +++ This event was the first time in the 20 year history of the training facility that a music concert has been performed. +++ The presentation at 37C3 will be the first time this talk is being presented publicly. ++ Additionally there will be a full Ptelepathetique concert featuring Music of Mars (Please keep checking the schedule / Fahrplan for the announcement of the performance) Using the SuperCam microphone mounted on the Mars Perseverance Rover, recordings were made of the sounds of the Ingenuity rotorcraft as well as the popping sounds of laser sparking on stone.

Während das verbleibende CO2-Budget zur Einhaltung der 2°C-Grenze schneller als je zuvor schrumpft, wird der Ruf nach einfachen, technologischen Lösungen laut. Eine globale Abkühlung des Klimas durch Climate Engineering wird von der Politik gerne als Universallösung angepriesen. Aber können wir das CO2, das wir ausstoßen, so einfach aus der Luft saugen und mit „negativen Emissionen“ das Klima retten? Dr. Maria-Elena Vorrath forscht an der Universität Hamburg an Gesteinsverwitterung und Pflanzenkohle, zwei Methoden, die CO2 aus der Atmosphäre entziehen, und klärt in ihrem Vortrag über negative Emissionen, ihr globales Potential und den aktuellen Forschungsstand auf. Und es gibt Memes. Climate Engineering ist das menschliche Eingreifen mittels großskaliger Technologien, um das globale Klimasystem zu beeinflussen. Dank Hollywoodfilmen und gefährlichem Halbwissen kennen wir diverse Untergangsszenarien zu dem Thema, wissen aber kaum wie Fotosynthese und Gesteinsverwitterung uns Menschen zum Erreichen unserer Klimaziele weiterhelfen können. Dass Steine CO2 aus der Luft holen und Jahrmillionen speichern können, ist für die allermeisten Menschen neu. In meinem Vortrag möchte ich aufklären, warum CO2 Entnahme aus der Atmosphäre (Negative Emissionen) ein wichtiger Baustein der Netto-Null Klimastrategie sind und in welchen Formen diese umgesetzt werden kann. Neben der biologischen und geochemischen CO2-Entnahme durch Fotosynthese und Gesteinsverwitterung, gibt es noch elektrochemische Methoden, um CO2 direkt aus der Luft oder indirekt über das Meer zu entnehmen.

September 2020 ist unser Ehrenmitglied Marc-André Janizewski nach langer schwerer Krankheit gestorben. Wir verlieren einen engen Freund und Verfechter unserer Werte und Träume. Der CCC drückt allen Angehörigen, Freunden und engen Begleitern von André sein tiefstes Mitgefühl aus. Als „Pyonen“ sind Marc-André Janizewski und sein Mitstreiter Markus Ossevorth seit Jahrzehnten weit über Berlin hinaus als Pioniere der Open-Air-Kultur bekannt. André verstand es wie kaum ein anderer, kreative Netzwerke aus Künstlerinnen jeder Art zu formen. Diese unverkennbare Handschrift brachte die Pyonen und den CCC erstmalig 1999 zusammen: Beim Chaos Communication Camp entstand durch eine enge Kooperation beider Gruppen nicht nur ein Hacker-Camp, sondern ein utopisches Gesamtkunstwerk. Durch seine visuelle Kreativität hauchte André der Location und dem Event die besondere Magie ein, der sich niemand entziehen konnte und die für viele weitere Veranstaltungen des Clubs prägend wurde. Die gewachsene Freundschaft ebnete dem Club ganz neue Perspektiven, Wege und Möglichkeiten. Dies zeigte sich vor allem bei den nachfolgenden Camps, denen André jedes einzelne Mal mit seiner unverwechselbaren und außergewöhnlichen Raumgestaltung seinen persönlichen Stempel aufdrückte. Aber auch der Chaos Communication Congress und viele andere Veranstaltungen im Clubumfeld entwickelten sich durch seinen Einfluss zunehmend künstlerischer, diverser, utopischer. Nerd- und Partykultur verschmolzen zu einer neuen Community. Vielleicht wäre es ohne den „Realitätsfluchthelfer“ André so nie gekommen. Für den nicht zu selten mit gewichtigen gesellschaftlichen und dystopischen Themen beschäftigten Club boten die Leichtigkeit und Schönheit von Musik, Kultur und freiem Himmel eine wichtige Energiequelle: einen kurzen Moment der Utopie. André selbst blieb dabei immer zurückhaltend und still im Hintergrund. Mit Liebe zum Detail schuf er temporäre Räume und verträumte Situationen. Er selbst war zufrieden, wenn die Menschen sich daran erfreuten. Meist fand man ihn am Rande des Geschehens, gemütlich auf dem Sofa sitzend, das Treiben verträumt genießend. Nie drängte er sich ins Rampenlicht, nie verlangte er viel Anerkennung – und es sollte zwanzig Jahre dauern, bis wir das erste Mal mit ihm und Markus öffentlich auf die lange und intensive gemeinsame Zeit zurückblicken konnten: Auf dem letzten Camp sprachen die beiden mit Tim Pritlove über diese besondere Zusammenarbeit. Es ist allgemein bekannt, dass Ehrenmitgliedschaften vergeben werden, damit sich der Verein mit den Würdenträgern schmücken kann – nicht etwa umgekehrt. Wir sind stolz, dass „zewski“ und Markus seit 2016 Ehrenmitglieder des Chaos Computer Clubs sind. Wir sind voller Dankbarkeit für die schöne und weite Reise, auf der André uns als maßgeblicher Navigator begleitet hat. Seine unverkennbare Handschrift steckt in vielem, was den Chaos Computer Club und seine Veranstaltungen heute für tausende Menschen ausmacht. Wir hoffen, dass wir sie bewahren können. Unsere Gedanken sind bei Andrés Angehörigen, Freunden und engen Begleitern. Mach’s gut, André.
