-<p>Today, the animation figure Mickey Mouse finally was released from
-the corporate copyright prison, as the 1928 movie
-<a href="https://en.wikipedia.org/wiki/Steamboat_Willie">Steamboat
-Willie</a> entered the public domain in USA. Sadly the figure is
-still on probation, thanks to trademark laws and a the Disney
-corporations powerful pack of lawyers, as described in the 2017 article
-in <a href="https://priceonomics.com/how-mickey-mouse-evades-the-public-domain/">"How
-Mickey Mouse Evades the Public Domain"</a> from Priceonomics. On the
-positive side, the primary driver for repeated extentions of the
-duration of copyright has been Disney thanks to Mickey Mouse and the
-2028 movie, and as it now in the public domain I hope it will cause
-less urge to extend the already unreasonable long copyright
-duration.</p>
-
-<p>The first book I published, the 2004 book <a
-href="https://free-culture.cc/">"Free Culture" by Lawrence Lessig</a>,
-<a href="https://people.skolelinux.org/pere/publisher/#frikultur">published
-2015 in English, French and Norwegian Bokmål</a>, touch on the story
-of Disney pushed for extending the copyright duration in USA. It is a
-great book explaining problems with the current copyright regime and
-why we need Creative Commons movement, and I strongly recommend
-everyone to read it.</p>
-
-<p>This movie (with
-<a href="https://www.imdb.com/title/tt0019422/">IMDB ID tt0019422</a>)
-is now available from the Internet Archive. Two copies have been
-uploaded so far, one uploaded
-<a href="https://archive.org/details/SteamboatWillie">2015-11-04</a>
-(<a href="https://archive.org/download/SteamboatWillie/SteamboatWillie_archive.torrent">torrent</a>)
-and the other

-(<a href="https://archive.org/download/steamboat-willie-mickey/steamboat-willie-mickey_archive.torrent">torrent</a>).
-I am very happy to see
-<a href="https://people.skolelinux.org/pere/blog/Legal_to_share_more_than_16_000_movies_listed_on_IMDB_.html">the
-number of public domain movies</a> increasing. I look forward to
-when those are the majority. Perhaps it will reduce the urge of the
-copyright industry to control its customers.</p>

-<p>A more

-list of works entering the public domain in 2024</a> is available from

+ <title>121 packages in Debian mapped to hardware for automatic recommendation</title>

+ <description><p>For some years now, I have been working on a automatic hardware
+based package recommendation system for Debian and other Linux
+distributions. The isenkram system I started on back in 2013 now
+consist of two subsystems, one locating firmware files using the
+information provided by apt-file, and one matching hardware to
+packages using information provided by AppStream. The former is very
+similar to the mechanism implemented in debian-installer to pick the
+right firmware packages to install. This post is about the latter
+system. Thanks to steady progress and good help from both other
+Debian and upstream developers, I am happy to report that
+<a href="https://tracker.debian.org/pkg/isenkram">the Isenkram
+system</a> now are able to recommend 121 packages using information
+provided via
+<a href="https://www.freedesktop.org/wiki/Distributions/AppStream/">AppStream</a>.</p>
+
+<p>The mapping is done using modalias information provided by the
+kernel, the same information used by udev when creating device files,
+and the kernel when deciding which kernel modules to load. To get all
+the modalias identifiers relevant for your machine, you can run the
+following command on the command line:</p>
+
+<pre>
+find /sys/devices -name modalias -print0 | xargs -0 sort -u
+</pre>
+
+<p>The modalias identifiers can look something like this:</p>
+
+<pre>
+acpi:PNP0000
+cpu:type:x86,ven0000fam0006mod003F:feature:,0000,0001,0002,0003,0004,0005,0006,0007,0008,0009,000B,000C,000D,000E,000F,0010,0011,0013,0015,0016,0017,0018,0019,001A,001B,001C,001D,001F,002B,0034,003A,003B,003D,0068,006B,006C,006D,006F,0070,0072,0074,0075,0076,0078,0079,007C,0080,0081,0082,0083,0084,0085,0086,0087,0088,0089,008B,008C,008D,008E,008F,0091,0092,0093,0094,0095,0096,0097,0098,0099,009A,009B,009C,009D,009E,00C0,00C5,00E1,00E3,00EB,00ED,00F0,00F1,00F3,00F5,00F6,00F9,00FA,00FB,00FD,00FF,0100,0101,0102,0103,0111,0120,0121,0123,0125,0127,0128,0129,012A,012C,012D,0140,0160,0161,0165,016C,017B,01C0,01C1,01C2,01C4,01C5,01C6,01F9,024A,025A,025B,025C,025F,0282

+platform:serial8250
+scsi:t-0x05
+usb:v413CpA001d0000dc09dsc00dp00ic09isc00ip00in00
+</pre>
+
+<p>The entries above are a selection of the complete set available on
+a Dell PowerEdge R730 machine I have access to, to give an idea about
+the various styles of hardware identifiers presented in the modalias
+format. When looking up relevant packages in a Debian Testing
+installation on the same R730, I get this list of packages
+proposed:</p>
+
+<pre>
+% sudo isenkram-lookup
+firmware-bnx2x
+firmware-nvidia-graphics
+firmware-qlogic
+megactl
+wsl
+%
+</pre>
+
+<p>The list consist of firmware packages requested by kernel modules,
+as well packages with program to get the status from the RAID
+controller and to maintain the LAN console. When the edac-utils
+package providing tools to check the ECC RAM status will enter testing
+in a few days, it will also show up as a proposal from isenkram. In
+addition, once the mfiutil package we uploaded in October get past the
+NEW processing, it will also propose a tool to configure the RAID
+controller.</p>
+
+<p>Another example is the trusty old Lenovo Thinkpad X230, which have
+hardware handled by several packages in the archive. This is running
+on Debian Stable:</p>
+
+<pre>
+% isenkram-lookup
+beignet-opencl-icd
+bluez
+cheese
+ethtool
+firmware-iwlwifi
+firmware-misc-nonfree
+fprintd
+fprintd-demo
+gkrellm-thinkbat
+hdapsd
+libpam-fprintd
+pidgin-blinklight
+thinkfan
+tlp
+tp-smapi-dkms
+tpb
+%
+</pre>
+
+<p>Here there proposal consist of software to handle the camera,
+bluetooth, network card, wifi card, GPU, fan, fingerprint reader and
+acceleration sensor on the machine.</p>
+
+<p>Here is the complete set of packages currently providing hardware
+mapping via AppStream in Debian Unstable: air-quality-sensor,
+alsa-firmware-loaders, antpm, array-info, avarice, avrdude,
+bmusb-v4l2proxy, brltty, calibre, colorhug-client, concordance-common,
+consolekit, dahdi-firmware-nonfree, dahdi-linux, edac-utils,

+w1retap, wsl, xawtv, xinput-calibrator, xserver-xorg-input-wacom and
+xtrx-dkms.</p>
+
+<p>In addition to these, there are several
+<a href="https://udd.debian.org/cgi-bin/bts-usertags.cgi?user=pere%40hungry.com&tag=appstream-modalias">with
+patches pending in the Debian bug tracking system</a>, and even more
+where no-one wrote patches yet. Good candiates for the latter are
+packages
+<a href="https://udd.debian.org/lintian-tag.cgi?tag=appstream-metadata-missing-modalias-provide">with
+udev rules but no AppStream hardware information</a>.</p>
+
+<p>The isenkram system consist of two packages, isenkram-cli with the
+command line tools, and isenkram with a GUI background process. The
+latter will listen for dbus events from udev emitted when new hardware
+become available (like when inserting a USB dongle or discovering a
+new bluetooth device), look up the modalias entry for this piece of
+hardware in AppStream (and a hard coded list of mappings from isenkram
+- currently working hard to move this list to AppStream), and pop up a
+dialog proposing to install any not already installed packages
+supporting this hardware. It work very well today when inserting the
+LEGO Mindstorms RCX, NXT and EV3 controllers. :) If you want to make
+sure more hardware related packages get recommended, please help out
+fixing the remaining packages in Debian to provide AppStream metadata
+with hardware mappings.</p>

+ <description><p><a href="http://www.hungry.com/~pere/blog/What_is_the_most_supported_MIME_type_in_Debian_in_2018_.html">Seven</a>
+and
+<a href="http://www.hungry.com/~pere/blog/What_is_the_most_supported_MIME_type_in_Debian_.html">twelve</a>
+years ago, I measured what the most supported MIME type in Debian
+was</a>, first by analysing the desktop files in all packages in the
+archive, then by analysing the DEP-11 AppStream data set. I guess it
+is time to repeat the measurement, only for unstable as last time:</p>
+
+<p><strong>Debian Unstable:</strong></p>
+
+<pre>
+ count MIME type
+ ----- -----------------------
+ 63 image/png
+ 63 image/jpeg
+ 57 image/tiff
+ 54 image/gif
+ 51 image/bmp
+ 50 audio/mpeg
+ 48 text/plain
+ 42 audio/x-mp3
+ 40 application/ogg
+ 39 audio/x-wav
+ 39 audio/x-flac
+ 36 audio/x-vorbis+ogg
+ 35 audio/x-mpeg
+ 34 audio/x-mpegurl
+ 34 audio/ogg
+ 33 application/x-ogg
+ 32 audio/mp4
+ 31 audio/x-scpls
+ 31 application/pdf
+ 29 audio/x-ms-wma
+</pre>
+
+<p>The list was created like this using a sid chroot:</p>
+
+<pre>
+cat /var/lib/apt/lists/*sid*_dep11_Components-amd64.yml.gz | \
+ zcat | awk '/^ - \S+\/\S+$/ {print $2 }' | sort | \
+ uniq -c | sort -nr | head -20
+</pre>
+
+<p>It is nice to see that the same number of packages now support PNG
+and JPEG. Last time JPEG had more support than PNG. Most of the MIME
+types are known to me, but the 'audio/x-scpls' one I have no idea what
+represent, except it being an audio format. To find the packages
+claiming support for this format, the appstreamcli command from the
+appstream package can be used:
+
+<pre>
+% appstreamcli what-provides mediatype audio/x-scpls | grep Package: | sort -u
+Package: alsaplayer-common
+Package: amarok
+Package: audacious
+Package: brasero
+Package: celluloid
+Package: clapper
+Package: clementine
+Package: cynthiune.app
+Package: elisa
+Package: gtranscribe
+Package: kaffeine
+Package: kmplayer
+Package: kylin-burner
+Package: lollypop
+Package: mediaconch-gui
+Package: mediainfo-gui
+Package: mplayer-gui
+Package: mpv
+Package: mystiq
+Package: parlatype
+Package: parole
+Package: pragha
+Package: qmmp
+Package: rhythmbox
+Package: sayonara
+Package: shotcut
+Package: smplayer
+Package: soundconverter
+Package: strawberry
+Package: syncplay
+Package: vlc
+%
+</pre>
+
+<p>Look like several video and auto tools understand the format.
+Similarly one can check out the number of packages supporting the STL
+format commonly used for 3D printing:</p>
+
+<pre>
+% appstreamcli what-provides mediatype model/stl | grep Package: | sort -u
+Package: cura
+Package: freecad
+Package: open3d-viewer
+%
+</pre>
+
+<p>How strange the
+<a href="https://tracker.debian.org/pkg/slic3r">slic3r</a> and
+<a href="https://tracker.debian.org/pkg/slic3r-prusa">prusa-slicer</a>
+packages do not support STL. Perhaps just missing package metadata?
+Luckily the amount of package metadata in Debian is getting better,
+and hopefully this way of locating relevant packages for any file
+format will be the preferred one soon.

+ <description><p><a href="https://linuxcnc.org/">The LinuxCNC project</a> is
+trotting along. And I believe this great software system for
+numerical control of machines such as milling machines, lathes, plasma
+cutters, routers, cutting machines, robots and hexapods, would do even
+better with more in-person developer gatherings, so we plan to
+organise such gathering this summer too.</p>
+
+<p>This year we would like to invite to a small LinuxCNC and free
+software fabrication workshop/gathering in Norway this summer for the
+weekend starting July 4th 2025. New this year is the slightly larger
+scope, and we invite people also outside the LinuxCNC community to
+join. As earlier, we suggest to organize it as an
+<a href="https://en.wikipedia.org/wiki/Unconference">unconference</a>,
+where the participants create the program upon arrival.</p>
+
+<p>The location is a metal workshop 15 minutes drive away from to the
+Gardermoen airport (OSL), where there is a lot of space and a hotel only
+5 minutes away by car. We plan to fire up the barbeque in the evenings.</p>
+
+<p>Please let us know if you would like to join. We track the list of
+participants on <a href="https://pad.efn.no/p/linuxcnc-2025-norway">a
+simple pad</a>, please add yourself there if you are interested in joining.</p>
+
+<p><a href="https://www.nuugfoundation.no/">The NUUG Foundation</a> has on
+our request offered to handle any money involved with this gathering,
+in other words holding any sponsor funds and paying any bills.
+NUUG Foundation is a spinnoff from the NUUG member organisation here
+in Norway with long ties to the free software and open standards
+communities.</p>
+
+<p>As usual we hope to find sponsors to pay for food, lodging and travel.</p>
