I tried using the SimpleCaptcha plugin, which is included by default on GNU social, and also FacileCaptcha, which was created by XRevan86 (the admin of LoadAverage.org) but they only work with the classical interface. After searching for a while and talking to some people I was told of a Captcha-plugin for Qvitter: <a href="https://gitgud.io/panjoozek413/qvittersimplesecurity">QvitterSimpleSecurity</a>.</p> <h2>Install & Set Up QvitterSimpleSecurity on GNU Social</h2> <p>Go to your plugin directory (local/plugins or plugins) and clone the Git repository of the plugin we are talking about:</p> <p><code>$ git clone https://gitgud.io/panjoozek413/qvittersimplesecurity</code></p> <p>Rename the plugin directory (GNU social is case sensitive) to QvitterSimpleSecurity:</p> <p><code>$ mv qvittersimplesecurity QvitterSimpleSecurity</code></p> <p>To enable the plugin just add (using a text editor like e.g. nano) the following line to your config.php (in the root directory of your GNU Social installation):</p> <p><code>addPlugin('QvitterSimpleSecurity');</code></p> <p>Visit the registration page of Qvitter in order to check that the Captcha is working 馃檪</p> <p><a href="https://dalme.net/wp-content/uploads/2018/09/c126eb66eb7b1781a5c1af0151e1b6dede634ff08a6a1f263ecbd9c44c2cc89c.png"><img class="aligncenter size-full wp-image-167" src="https://dalme.net/wp-content/uploads/2018/09/c126eb66eb7b1781a5c1af0151e1b6dede634ff08a6a1f263ecbd9c44c2cc89c.png" alt="" width="589" height="551" /></a></p> </div>  </article>  <article id="post-117" class="post-117 post type-post status-publish format-standard hentry category-git"> <header class="entry-header"> <h1 class="entry-title"> <a href="https://dalme.net/2018/07/how-to-mirror-a-git-repository/" rel="bookmark">How to mirror a git repository</a> </h1> </header>  <div class="entry-content"> <p><a href="https://dalme.net/wp-content/uploads/2018/01/git.png"><img class="aligncenter size-full wp-image-90" src="https://dalme.net/wp-content/uploads/2018/01/git.png" alt="" width="588" height="200" srcset="https://dalme.net/wp-content/uploads/2018/01/git.png 588w, https://dalme.net/wp-content/uploads/2018/01/git-300x102.png 300w" sizes="(max-width: 588px) 100vw, 588px" /></a>As I was working on libgnusocial I went into trouble because we have three different git repositories: <a href="https://gitlab.com/DalmeGNU/libgnusocial">Gitlab</a>, <a href="https://github.com/dalmemail/libgnusocial">Github</a> & <a href="https://code.freedombone.net/bashrc/libgnusocial">code.freedombone.net</a> and I wanted to keep them all updated. To do this I just work with one (at Gitlab) and I treat the others as mirrors. First of all, to mirror a git repository we need to clone it using the “mirror” argument:</p> <p><code>$ git clone --mirror https://gitlab.com/user/repository</code></p> <p>Then move into the cloned repository directory (which git ends in “.git” due to the mirror cloning process):</p> <p><code>$ cd repository.git</code></p> <p>And finally push into an empty repository or an outdated mirror of our repository:</p> <p><code>$ git push --mirror https://gitlab.com/user/another_repository</code></p> </div>  </article>  <article id="post-105" class="post-105 post type-post status-publish format-standard has-post-thumbnail hentry category-i3wm"> <header class="entry-header"> <h1 class="entry-title"> <a href="https://dalme.net/2018/01/set-random-wallpaper-in-i3wm/" rel="bookmark">Set random wallpaper in i3wm</a> </h1> <a href="https://dalme.net/2018/01/set-random-wallpaper-in-i3wm/" title="Permalink to Set random wallpaper in i3wm"> <img width="806" height="300" src="https://dalme.net/wp-content/uploads/2018/01/i3wm-806x300.png" class="attachment-sitepoint_base_theme_post_feature_full_width size-sitepoint_base_theme_post_feature_full_width wp-post-image" alt="" /> </a> </header>  <div class="entry-content"> <p style="text-align: center;"><em>“i3 is a <a href="http://en.wikipedia.org/wiki/Tiling_window_manager">tiling window manager</a>, completely written from scratch.
