But the real trick lies in keeping it. This came to mind while I was watching <a target=_blank href="https://www.youtube.com/watch?v=gCXL7N9NNq8">a video about one of Bambu Labs’ very impressive-looking Apple-style “It Just Works” 3D printers</a>, and felt myself drawing a parallel between the world of 3D printing and our more familiar KDE world.</p><p>As I <a target=_blank href=https://pointieststick.com/2025/03/10/personal-and-professional-updates-announcing-techpaladin-software/>mentioned recently</a>, my first real introduction to the world of free software was 15 years ago with 3D printers, back when the field was dominated by <a target=_blank href=https://en.wikipedia.org/wiki/RepRap>RepRap</a> hackers designing open hardware and software. And last year, I bought a new printer for the first time in over a decade. After drooling over a bunch of very cool <a target=_blank href=https://www.vorondesign.com/>Vorons</a>, I eventually settled on a <a target=_blank href=https://blog.prusa3d.com/announcing-original-prusa-mk4_76585/>Prusa Mk4</a> instead of a different Bambu printer that looked very impressive at the time: printing faster, having an enclosed chamber and smoother wireless functionality, being cheaper, and looking prettier.</p><p>But the Prusa felt like KDE: simple by default, but powerful when needed. Big friendly community. Built by a company led by one of the early RepRap hardware hackers. Buying it was investing in the people helping to keep their part of the industry open, rather than private. No spyware, no lock-in, no phone app or internet connection needed. Can’t be bricked if the company goes out of business. Open, hackable, humane, trustworthy.</p><p>I’m making this sound like the decision was some sort of ideological compromise, but the Prusa Mk4 is also <em>excellent</em>. It’s as good or better in many ways, almost as much in others, and its UX still pretty polished. Maybe it’s not <em>Apple</em> polished, but it’s very easy to use and produces great prints. I did have to invest a bit more time and money into the Prusa upfront, but now I have a tool I can truly rely on, not because it’s got a seamless auto-updating cloud-based AI-enabled UI, but because it <em>doesn’t</em>.</p><p>And since then, both companies went in exactly in the directions I expected: Prusa released a new version of their printer that’s cheaper and better, plus a <a target=_blank href=https://www.prusa3d.com/product/original-prusa-mk4-to-mk4s-upgrade-kit-7/>$100 kit for existing owners</a> so they don’t have to buy a whole new thing… while Bambu released a firmware upgrade <a target=_blank href=https://wiki.rossmanngroup.com/wiki/Bambu_Lab_Authorization_Control_System>that lets them control how your Bambu printer can be used</a>.</p><p>It Just Works… until it doesn’t.</p><p>I’m glad I went with the Prusa, the same way we’re all glad we went with KDE over Apple or Microsoft. In KDE we know this well, so it’s up to us to spread the message to everyone else: <strong>resist the lure of “easier now, screwed later.”</strong> This is where the big commercial offerings start to fail: anything proprietary and closed source that Just Works may simply stop working at any time. You’ll invest in it, and it’ll work out great for a while, but then start to worsen, break, or exploit you.</p><p>Even as we invest in making our software easier to use, we need to level the playing field by advertising our advantages in ownership, privacy, personalization, and freedom. Our software is trustworthy because it can’t be taken away by us or anyone else; you’ll be able to use it over the long term, developing skills and efficiencies over time. Investing in KDE is investing in yourself, rather than someone else’s bottom line.</p></div></div></div></div></div><div class=single-post id=4><h3>Saturday, 5 April 2025</h3><div class="row m-0 justify-content-center"><div class="col-12 p-0"><div class="card mb-3 card-sm-border-0 p-0"><div class="row m-0 border-bottom"><div class="col card-header pl-1 pl-md-3 border-0"><h3 class="mt-0 h5"><a href=https://www.volkerkrause.eu/2025/04/05/osm-fossgis-conference-2025.html target=_blank rel="noopener noreferrer">FOSSGIS Conference 2025</a> <a href=https://planet.kde.org/volker-krause-2025-04-05-fossgis-conference-2025/ class=post-anchor>🔗</a></h3><div class="d-flex flex-fill align-items-center"><a href=https://www.volkerkrause.eu/ target=_blank rel="noopener noreferrer"><img height=51px class="my-auto me-2" src=https://planet.kde.org/hackergotchi/vkrause.jpg></a><div class="d-flex flex-column"><span><a href=https://www.volkerkrause.eu/ target=_blank rel="noopener noreferrer">Volker Krause</a> <a href=https://webchat.kde.org/ target=_blank><span class="badge bg-secondary"><img width=12px height=12px src=https://planet.kde.org/img/matrix.svg> @vkrause:kde.org</span> </a></span><span class=text-muted>07:45 +00:00</span></div><a href=https://www.volkerkrause.eu/feed.xml target=_blank rel="noopener noreferrer" class="ms-auto post-feed" title="Thoughts on KDE, Qt, Free Software and software engineering.">Atom <i class="icon icon_rss"></i></a></div></div></div><div class="card-body markdown"><p>Last week I attended this year’s <a target=_blank href=https://fossgis-konferenz.de/2025/>FOSSGIS Konferenz</a> in Münster, Germany, focusing on public transport and indoor navigation topics.</p><figure><img src=https://www.volkerkrause.eu/assets/posts/203/fossgis-konferenz-2025-group-photo.jpg alt="Group photo of the FOSSGIS 2025 conference attendees." loading=lazy><figcaption>Photo by FOSSGIS e.V./Sergey Mukhametov, CC-BY-SA</figcaption></figure><h3 id=indoor-navigation>Indoor Navigation</h3><p>We use <a target=_blank href=https://commits.kde.org/kosmindoormap>indoor map rendering</a> and <a href=//www.volkerkrause.eu/2024/03/02/osm-hackweekend-karlsruhe-february-2024.html>indoor routing</a> in <a target=_blank href=https://apps.kde.org/itinerary>KDE Itinerary</a> for e.g. train stations. There were a number of interesting talks and discussions in that area:</p><ul><li>A 2.5D visualization of buildings and especially of the vertical connectivity (stairs, elevators, etc) between floors, by a team from TU Dresden, with a <a target=_blank href=https://github.com/Accessible-InfoPoint/2.5D-Indoor-Maps>free implementation available</a>. Compared to our current 2D view this makes it easier to understand how to move between floors, but it brings new challenges as well (<a target=_blank href=https://pretalx.com/fossgis2025/talk/RMMA9H/>video</a>).</li><li>Indoor localization and routing including an AR demo by the German Federal Agency for Cartography and Geodesy (BKG). The routing is done via Unity, which uses the same library underneath that we use as well. Localization is using a mix of sensors available in normal smart phones, which is particularly interesting for us. Unfortunately like most similar systems the implementation isn’t published (<a target=_blank href=https://pretalx.com/fossgis2025/talk/CFANYR/>talk</a>).</li><li>Work on <a target=_blank href=https://community.openstreetmap.org/t/proposed-import-of-the-indoor-data-offered-for-osm-by-the-technical-university-of-munich-tum/127003>importing building geometries for 400+ buildings of TU München</a>, using <a target=_blank href=https://en.wikipedia.org/wiki/Industry_Foundation_Classes>IFC</a> <a target=_blank href=https://en.wikipedia.org/wiki/Building_information_modeling>BIM</a> data. That’s the best way to get high-quality building geometries into <a target=_blank href=https://openstreetmap.org>OSM</a> I think, but while there has been previous work on building an import toolchain for this, getting the actual BIM data has been elusive due to various concerns by building owners.</li><li>Modelling and tagging of infrastructure in and around train stations in OSM (<a target=_blank href=https://wiki.openstreetmap.org/wiki/FOSSGIS_2025/OSM-Samstag/Ergebnisse#Gute_Praxis_-_Bahnhof_aus_Sicht_der_Nutzenden>session notes</a>).</li></ul><p>And of course there was also the yearly offline FOSSGIS edition of the OSM indoor meetup for connecting everyone working on that subject (<a target=_blank href=https://wiki.openstreetmap.org/wiki/Indoor_OSM_user_meeting_at_FOSSGIS_Konferenz_2025>translated session notes</a>).</p><h3 id=open-transport>Open Transport</h3><p>The other big topic for me was public transport routing, which we do in <a target=_blank href=https://transitous.org>Transitous</a>, for use in Itinerary and many other apps.</p><p>There were several talks and poster sessions in that area:</p><ul><li>Katharina presented her work on an <a target=_blank href=https://pretalx.com/fossgis2025/talk/YJTBAB/>explorative long distance journey planning UI</a> (English version from FOSDEM <a target=_blank href=https://fosdem.org/2025/schedule/event/fosdem-2025-6205-explorative-routing/>here</a>). I’d really like to see Transitous become a platform to build such innovative UIs on top, so you can focus on that rather than redoing the entire data handling and routing.</li><li>My own <a target=_blank href=https://pretalx.com/fossgis2025/talk/TJVVDZ/>talk introducing Transitous</a>.</li><li>Felix spoke about the <a target=_blank href=https://pretalx.com/fossgis2025/talk/HGUKFM/>routing capabilities of MOTIS</a>, the routing engine Transitou is built upon.</li><li>René showed work on <a target=_blank href=https://pretalx.com/fossgis2025/talk/AH98HQ/>developing and standardizing data formats for describing public transport vehicles</a> in great detail. That’s badly needed for considering accessibility during routing, the current modelling in <a target=_blank href=https://gtfs.org>GTFS</a> (basically “wheelchair=yes|no”) is way to simplistic for that.</li><li>A talk about <a target=_blank href=https://pretalx.com/fossgis2025/talk/UKULHF/>DB Regio’s vehicle position processing</a>. Especially deriving delay estimates from position data is highly relevant for Transitous, but unfortunately neither their data nor their code seems to be openly available.</li></ul><p>There also has been a lot of hallway track discussion on this:</p><ul><li>Together with several <a target=_blank href=https://motis-project.de/>MOTIS</a> users and contributors we reviewed and updated the <a target=_blank href=https://github.com/motis-project/motis/issues/635>MOTIS feature wish list</a>.</li><li>There are ideas for collaborating on a public transport optimized geocoder, between <a target=_blank href=https://nominatim.openstreetmap.org/ui/search.html>Nominatim</a>, Transitous and other people needing this. Currently this is usually based on OSM data, but additionally using schedule data would allow things like considering the number of lines or trips at a stop for ranking. “Meta-stations” were another subject, ie. if you select “Paris” as the destination any of its major railway stations and airports would be expected destination, rather than just the first stop inside the city boundary.</li><li>GTFS data quality was a prevalent topic, including during the offline FOSSGIS edition of the <a target=_blank href=https://github.com/transportkollektiv/meetup/wiki>Open Transport Meetup</a>, and now also with the German Federal Agency for Cartography and Geodesy (BKG) joining everyone else in exploring the wonders of this. More eyes (and more pressure) can only help here.</li><li>Possible datasets for elevation models usable for routing, for Transitous something particularly interesting for first/last mile bike routing.</li><li>Plans for a Transitous sprint/hack weekend are getting a bit more concrete, with two promising options in June/July.</li><li>Ideas for improving Transitous’ outreach activities and social media presence/PR.</li></ul><p>Also, if you are interested or involved in FOSS or Open Data topics around mobility/transit keep October 17/18 free, there’s an exciting announcement coming up shortly.</p><h3 id=osm>OSM</h3><p>The FOSSGIS conference is of course much larger than just those two topics, and while those kept me occupied most of the time I managed to pick up a few more things as well:</p><ul><li>Pirmin’s talk on <a target=_blank href=https://pretalx.com/fossgis2025/talk/HEWMUB/>showing realtime data layers</a> with MapLibre should come in handy for getting live updates onto the <a target=_blank href=https://alerts.kde.org/alert/map>map view</a> for monitoring our <a target=_blank href=https://invent.kde.org/webapps/foss-public-alert-server>emergency and weather alert aggregation server</a>. This talk also featured a Transitous live demo, something I didn’t dare doing myself.</li><li>Frederik’s <a target=_blank href=https://pretalx.com/fossgis2025/talk/FCQVSQ/>work on PostPass</a> could turn out to be a vastly more efficient way to extract region or timezone boundary polygons than our current approach that takes hours and needs a full local OSM planet file.</li></ul><p>And as always when hanging out with people from different communities there’s experiences to share on things like mentorship and funding programs as well as nowadays sadly also on defense measures to protect our infrastructure from overly aggressive AI crawler bots.</p></div></div></div></div></div><div class=single-post id=5><div class="row m-0 justify-content-center"><div class="col-12 p-0"><div class="card mb-3 card-sm-border-0 p-0"><div class="row m-0 border-bottom"><div class="col card-header pl-1 pl-md-3 border-0"><h3 class="mt-0 h5"><a href=https://blogs.kde.org/2025/04/05/this-week-in-plasma-polish-and-stability/ target=_blank rel="noopener noreferrer">This Week in Plasma: polish and stability</a> <a href=https://planet.kde.org/nate-graham-2025-04-05-this-week-in-plasma-polish-and-stability/ class=post-anchor>🔗</a></h3><div class="d-flex flex-fill align-items-center"><a href=https://blogs.kde.org/authors/nategraham/ target=_blank rel="noopener noreferrer"><img height=51px class="my-auto me-2" src=https://planet.kde.org/hackergotchi/ngraham.png></a><div class="d-flex flex-column"><span><a href=https://blogs.kde.org/authors/nategraham/ target=_blank rel="noopener noreferrer">Nate Graham</a> <span class="badge bg-dark"><img src=https://planet.kde.org/img/irc.svg> ngraham</span> </span><span class=text-muted>02:00 +00:00</span></div><a href=https://blogs.kde.org/authors/nategraham/index.xml target=_blank rel="noopener noreferrer" class="ms-auto post-feed" title="Recent content in Nate Graham on KDE Blogs">RSS <i class="icon icon_rss"></i></a></div></div></div><div class="card-body markdown"><p>Welcome to a new issue of "This Week in Plasma"!

QListWidget and QTableWidget have out of the box support for replacing the value of existing items when doing that, but there aren't many use cases for that. What is much more common is to associate a custom semantic to such a drop.

In this post, I'll talk about doing this for layouts.</p><h2 id=inspiration>Inspiration</h2><p>In the past, I needed to open two connections to the same host over <code>ssh</code> , and change to two different directories.

Unfortuately, it can't do anything else. We can, however, use profiles and the Quick Commands plugin to make the panes more useful.</p><p><strong>Use case:</strong> See the output of different commands in the same window. For instance, you could be running <code>htop</code> in one pane and open your favorite editor in another.</p><p>Here's an overview of the steps:</p><ul><li>Set up a layout</li><li>Use QuickCommands to run things in the panes</li></ul><h2 id=set-up-a-layout>Set up a layout</h2><p>Unfortunately, the <a target=_blank href=https://docs.kde.org/stable5/en/konsole/konsole/command-line-options.html>online documentation for Konsole command line options</a> doesn't say much about how to create a layout, or the format of its JSON file. It only mentions the command line flag <code>--layout</code>. <em>Also make a note of <code>-e</code> which allows you to execute a command.</em></p><p>Fortunately, creating the layout is pretty easy. Note that a layout is limited to one tab. It will only save the window splits, nothing else. No profiles, directories, etc.</p><ol><li>Set up a tab in Konsole with the splits you want it to have</li><li>Use <code>View -> Save Tab Layout</code> to save it to a .json file. (I personally recommend keeping these in a specific directory so they're easy to find later, and for scripting. I use <code>~/konsole-layouts</code>).</li><li>You can then use <code>konsole --layout ~/layout-name.json</code> to load konsole with a tab that has the splits you saved.</li></ol><h2 id=use-quick-commands-to-do-useful-things-in-your-layout>Use Quick Commands to do useful things in your layout</h2><p>As mentioned above, you can only save splits. you can't associate a profile, or run a command directly like you can with the tilix or kitty terminals. This has <a target=_blank href="https://bugs.kde.org/show_bug.cgi?id=455143">been requested</a>. In the meantime, an easy thing you <em>can</em> do is load a layout and then load a profile manually in each pane. This is where Quick Commands come in. These are under Plugins - Quick Commands. (If you don't see this, contact your distro / the place you installed Konsole from).</p><p>You can use Quick Commands to run a command in each pane. You can also launch a profile (with different colors etc) that runs a command (<a target=_blank href=https://blogs.kde.org/2024/06/11/konsole-layout-automation-part-1/>part 1</a> showed how these might be used). Note, however, that running <code>konsole</code> itself from here will launch a new Konsole window.</p><p>End each command with <code>|| return</code> so that you get to a prompt if the command fails.</p><p>Examples</p><pre tabindex=0><code>htop || return </code></pre><p>So, after you've launched Konsole with your layout as described above, you can do this: Go to <code>Plugins -> Show Quick Commands</code> Add commands you'd like to run in this session. Now, focus the pane and run a command.</p><p>Using these steps, I can run <code>htop</code> in one pane and <code>nvtop</code> in the other.</p><p>After you've gotten familiar with tabs and layouts, you can make a decently powerful Konsole session. Combine these with a shell function, and you can invoke that session very easily.</p><h2 id=this-is-still-too-manual>This is still too manual!</h2><p>You're right. This post is about automating Konsole and having to click on things is not exactly that. You can use dbus commands in a script to load your tab layout and then run commands in each pane without using Quick Commands.</p><p>As we saw in the <a target=_blank href=https://blogs.kde.org/2024/06/11/konsole-layout-automation-part-1/>last post</a>, you can use profiles to customize color schemes and launch commands. We can call those from a script in a layout.
