  15 and
  16 &lt;a href=&quot;http://www.hungry.com/~pere/blog/What_is_the_most_supported_MIME_type_in_Debian_.html&quot;&gt;twelve&lt;/a&gt;
  17 years ago, I measured what the most supported MIME type in Debian
  18 was&lt;/a&gt;, first by analysing the desktop files in all packages in the
  19 archive, then by analysing the DEP-11 AppStream data set.  I guess it
  20 is time to repeat the measurement, only for unstable as last time:&lt;/p&gt;
  21
  22 &lt;p&gt;&lt;strong&gt;Debian Unstable:&lt;/strong&gt;&lt;/p&gt;
  23
  24 &lt;pre&gt;
  25   count MIME type
  26   ----- -----------------------
  27      63 image/png
  28      63 image/jpeg
  29      57 image/tiff
  30      54 image/gif
  31      51 image/bmp
  32      50 audio/mpeg
  33      48 text/plain
  34      42 audio/x-mp3
  35      40 application/ogg
  36      39 audio/x-wav
  37      39 audio/x-flac
  38      36 audio/x-vorbis+ogg
  39      35 audio/x-mpeg
  40      34 audio/x-mpegurl
  41      34 audio/ogg
  42      33 application/x-ogg
  43      32 audio/mp4
  44      31 audio/x-scpls
  45      31 application/pdf
  46      29 audio/x-ms-wma
  47 &lt;/pre&gt;
  48
  49 &lt;p&gt;The list was created like this using a sid chroot:&lt;/p&gt;
  50
  51 &lt;pre&gt;
  52 cat /var/lib/apt/lists/*sid*_dep11_Components-amd64.yml.gz | \
  53   zcat | awk &#39;/^  - \S+\/\S+$/ {print $2 }&#39; | sort | \
  54   uniq -c | sort -nr | head -20
  55 &lt;/pre&gt;
  56
  57 &lt;p&gt;It is nice to see that the same number of packages now support PNG
  58 and JPEG.  Last time JPEG had more support than PNG.  Most of the MIME
  59 types are known to me, but the &#39;audio/x-scpls&#39; one I have no idea what
  60 represent, except it being an audio format.  To find the packages
  61 claiming support for this format, the appstreamcli command from the
  62 appstream package can be used:
  63
  64 &lt;pre&gt;
  65 % appstreamcli what-provides mediatype audio/x-scpls | grep Package: | sort -u
  66 Package: alsaplayer-common
  67 Package: amarok
  68 Package: audacious
  69 Package: brasero
  70 Package: celluloid
  71 Package: clapper
  72 Package: clementine
  73 Package: cynthiune.app
  74 Package: elisa
  75 Package: gtranscribe
  76 Package: kaffeine
  77 Package: kmplayer
  78 Package: kylin-burner
  79 Package: lollypop
  80 Package: mediaconch-gui
  81 Package: mediainfo-gui
  82 Package: mplayer-gui
  83 Package: mpv
  84 Package: mystiq
  85 Package: parlatype
  86 Package: parole
  87 Package: pragha
  88 Package: qmmp
  89 Package: rhythmbox
  90 Package: sayonara
  91 Package: shotcut
  92 Package: smplayer
  93 Package: soundconverter
  94 Package: strawberry
  95 Package: syncplay
  96 Package: vlc
  97 %
  98 &lt;/pre&gt;
  99
 100 &lt;p&gt;Look like several video and auto tools understand the format.
 101 Similarly one can check out the number of packages supporting the STL
 102 format commonly used for 3D printing:&lt;/p&gt;
 103
 104 &lt;pre&gt;
 105 % appstreamcli what-provides mediatype model/stl | grep Package: | sort -u
 106 Package: cura
 107 Package: freecad
 108 Package: open3d-viewer
 109 %
 110 &lt;/pre&gt;
 111
 112 &lt;p&gt;How strange the
 113 &lt;a href=&quot;https://tracker.debian.org/pkg/slic3r&quot;&gt;slic3r&lt;/a&gt; and
 114 &lt;a href=&quot;https://tracker.debian.org/pkg/slic3r-prusa&quot;&gt;prusa-slicer&lt;/a&gt;
 115 packages do not support STL.  Perhaps just missing package metadata?
 116 Luckily the amount of package metadata in Debian is getting better,
 117 and hopefully this way of locating relevant packages for any file
 118 format will be the preferred one soon.

 131                 <description>&lt;p&gt;&lt;a href=&quot;https://linuxcnc.org/&quot;&gt;The LinuxCNC project&lt;/a&gt; is
 132 trotting along.  And I believe this great software system for
 133 numerical control of machines such as milling machines, lathes, plasma
 134 cutters, routers, cutting machines, robots and hexapods, would do even
 135 better with more in-person developer gatherings, so we plan to
 136 organise such gathering this summer too.&lt;/p&gt;
 137
 138 &lt;p&gt;This year we would like to invite to a small LinuxCNC and free
 139 software fabrication workshop/gathering in Norway this summer for the
 140 weekend starting July 4th 2025.  New this year is the slightly larger
 141 scope, and we invite people also outside the LinuxCNC community to
 142 join.  As earlier, we suggest to organize it as an
 143 &lt;a href=&quot;https://en.wikipedia.org/wiki/Unconference&quot;&gt;unconference&lt;/a&gt;,
 144 where the participants create the program upon arrival.&lt;/p&gt;
 145
 146 &lt;p&gt;The location is a metal workshop 15 minutes drive away from to the
 147 Gardermoen airport (OSL), where there is a lot of space and a hotel only
 148 5 minutes away by car. We plan to fire up the barbeque in the evenings.&lt;/p&gt;
 149
 150 &lt;p&gt;Please let us know if you would like to join.  We track the list of
 151 participants on &lt;a href=&quot;https://pad.efn.no/p/linuxcnc-2025-norway&quot;&gt;a
 152 simple pad&lt;/a&gt;, please add yourself there if you are interested in joining.&lt;/p&gt;
 153
 154 &lt;p&gt;&lt;a href=&quot;https://www.nuugfoundation.no/&quot;&gt;The NUUG Foundation&lt;/a&gt; has on
 155 our request offered to handle any money involved with this gathering,
 156 in other words holding any sponsor funds and paying any bills.
 157 NUUG Foundation is a spinnoff from the NUUG member organisation here
 158 in Norway with long ties to the free software and open standards
 159 communities.&lt;/p&gt;
 160
 161 &lt;p&gt;As usual we hope to find sponsors to pay for food, lodging and travel.&lt;/p&gt;
 162
 163 &lt;p&gt;As usual, if you use Bitcoin and want to show your support of my
 164 activities, please send Bitcoin donations to my address
