  32         <p>Linux desktop systems
  33 <a href="https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html">have
  34 standardized</a> how programs present themselves to the desktop
  35 system.  If a package include a .desktop file in
  36 /usr/share/applications/, Gnome, KDE, LXDE, Xfce and the other desktop
  37 environments will pick up the file and use its content to generate the
  38 menu of available programs in the system.  A lesser known fact is that
  39 a package can also explain to the desktop system how to recognize the
  40 files created by the program in question, and use it to open these
  41 files on request, for example via a GUI file browser.</p>
  42
  43 <p>A while back I ran into a package that did not tell the desktop
  44 system how to recognize its files and was not used to open its files
  45 in the file browser and fixed it.  In the process I wrote a simple
  46 debian/tests/ script to ensure the setup keep working.  It might be
  47 useful for other packages too, to ensure any future version of the
  48 package keep handling its own files.</p>
  49
  50 <p>For this to work the file format need a useful MIME type that can
  51 be used to identify the format.  If the file format do not yet have a
  52 MIME type, it should define one and preferably also
  53 <a href="https://www.iana.org/assignments/media-types/media-types.xhtml">register
  54 it with IANA</a> to ensure the MIME type string is reserved.</p>
  55
  56 <p>The script uses the <tt>xdg-mime</tt> program from xdg-utils to
  57 query the database of standardized package information and ensure it
  58 return sensible values.  It also need the location of an example file
  59 for xdg-mime to guess the format of.</p>

 124         <p>While reading a
 125 <a href="https://sneak.berlin/20230115/macos-scans-your-local-files-now/">blog
 126 post claiming MacOS X recently started scanning local files and
 127 reporting information about them to Apple</a>, even on a machine where
 128 all such callback features had been disabled, I came across a
 129 description of the Little Snitch application for MacOS X.  It seemed
 130 like a very nice tool to have in the tool box, and I decided to see if
 131 something similar was available for Linux.</p>
 132
 133 <p>It did not take long to find
 134 <a href="https://github.com/evilsocket/opensnitch">the OpenSnitch
 135 package</a>, which has been in development since 2017, and now is in
 136 version 1.5.0.  It has had a
 137 <a href="https://bugs.debian.org/909567">request for Debian
 138 packaging</a> since 2018, but no-one completed the job so far.  Just
 139 for fun, I decided to see if I could help, and I was very happy to
 140 discover that
 141 <a href="https://github.com/evilsocket/opensnitch/issues/304">upstream
 142 want a Debian package too</a>.</p>
 143
 144 <p>After struggling a bit with getting the program to run, figuring
 145 out building Go programs (and a little failed detour to look at eBPF
 146 builds too - help needed), I am very happy to report that I am
 147 sponsoring upstream to maintain the package in Debian, and it has
 148 since this morning been waiting in NEW for the ftpmasters to have a
 149 look.  Perhaps it can get into the archive in time for the Bookworm
 150 release?</p>

 175         <p>I watched <a href="https://yewtu.be/watch?v=jmKUV3aNLjk">a 2015
 176 video from Andreas Schiffler</a> the other day, where he set up
 177 <a href="https://linuxcnc.org/">LinuxCNC</a> to send status
 178 information to the MQTT broker IBM Bluemix.  As I also use MQTT for
 179 graphing, it occured to me that a generic MQTT LinuxCNC component
 180 would be useful and I set out to implement it.  Today I got the first
 181 draft limping along and submitted as
 182 <a href="https://github.com/LinuxCNC/linuxcnc/pull/2253">a patch to the
 183 LinuxCNC project</a>.</p>
 184
 185 <p>The simple part was setting up the MQTT publishing code in Python.
 186 I already have set up other parts submitting data to my Mosquito MQTT
 187 broker, so I could reuse that code.  Writing a LinuxCNC component in
 188 Python as new to me, but using existing examples in the code
 189 repository and the extensive documentation, this was fairly straight
 190 forward.  The hardest part was creating a automated test for the
 191 component to ensure it was working.  Testing it in a simulated
 192 LinuxCNC machine proved very useful, as I discovered features I needed
 193 that I had not thought of yet, and adjusted the code quite a bit to
 194 make it easier to test without a operational MQTT broker
 195 available.</p>
 196
 197 <p>The draft is ready and working, but I am unsure which LinuxCNC HAL
 198 pins I should collect and publish by default (in other words, the
 199 default set of information pieces published), and how to get the
 200 machine name from the LinuxCNC INI file.  The latter is a minor
 201 detail, but I expect it would be useful in a setup with several
 202 machines available.  I am hoping for feedback from the experienced
 203 LinuxCNC developers and users, to make the component even better
 204 before it can go into the mainland LinuxCNC code base.</p>
 205
 206 <p>Since I started on the MQTT component, I came across
 207 <a href="https://yewtu.be/watch?v=Bqa2grG0XtA">another video from Kent
 208 VanderVelden</a> where he combine LinuxCNC with a set of screen glasses
 209 controlled by a Raspberry Pi, and it occured to me that it would
 210 be useful for such use cases if LinuxCNC also provided a REST API for
 211 querying its status.  I hope to start on such component once the MQTT
 212 component is working well.</p>
