+      <div class="date"> 9th July 2018</div>
+      <div class="body"><p>Five years ago,
+<a href="http://people.skolelinux.org/pere/blog/What_is_the_most_supported_MIME_type_in_Debian_.html">I
+measured what the most supported MIME type in Debian was</a>, by
+analysing the desktop files in all packages in the archive.  Since
+then, the DEP-11 AppStream system has been put into production, making
+the task a lot easier.  This made me want to repeat the measurement,
+to see how much things changed.  Here are the new numbers, for
+unstable only this time:
+
+<p><strong>Debian Unstable:</strong></p>
+
+<pre>
+  count MIME type
+  ----- -----------------------
+     56 image/jpeg
+     55 image/png
+     49 image/tiff
+     48 image/gif
+     39 image/bmp
+     38 text/plain
+     37 audio/mpeg
+     34 application/ogg
+     33 audio/x-flac
+     32 audio/x-mp3
+     30 audio/x-wav
+     30 audio/x-vorbis+ogg
+     29 image/x-portable-pixmap
+     27 inode/directory
+     27 image/x-portable-bitmap
+     27 audio/x-mpeg
+     26 application/x-ogg
+     25 audio/x-mpegurl
+     25 audio/ogg
+     24 text/html
+</pre>
+
+<p>The list was created like this using a sid chroot: "cat
+/var/lib/apt/lists/*sid*_dep11_Components-amd64.yml.gz| zcat | awk '/^
+- \S+\/\S+$/ {print $2 }' | sort | uniq -c | sort -nr | head -20"</p>
+
+<p>It is interesting to see how image formats have passed text/plain
+as the most announced supported MIME type.  These days, thanks to the
+AppStream system, if you run into a file format you do not know, and
+want to figure out which packages support the format, you can find the
+MIME type of the file using "file --mime &lt;filename&gt;", and then
+look up all packages announcing support for this format in their
+AppStream metadata (XML or .desktop file) using "appstreamcli
+what-provides mimetype &lt;mime-type&gt;.  For example if you, like
+me, want to know which packages support inode/directory, you can get a
+list like this:</p>
+
+<p><blockquote><pre>
+% appstreamcli what-provides mimetype inode/directory | grep Package: | sort
+Package: anjuta
+Package: audacious
+Package: baobab
+Package: cervisia
+Package: chirp
+Package: dolphin
+Package: doublecmd-common
+Package: easytag
+Package: enlightenment
+Package: ephoto
+Package: filelight
+Package: gwenview
+Package: k4dirstat
+Package: kaffeine
+Package: kdesvn
+Package: kid3
+Package: kid3-qt
+Package: nautilus
+Package: nemo
+Package: pcmanfm
+Package: pcmanfm-qt
+Package: qweborf
+Package: ranger
+Package: sirikali
+Package: spacefm
+Package: spacefm
+Package: vifm
+%
+</pre></blockquote></p>
+
+<p>Using the same method, I can quickly discover that the Sketchup file
+format is not yet supported by any package in Debian:</p>
+
+<p><blockquote><pre>
+% appstreamcli what-provides mimetype  application/vnd.sketchup.skp
+Could not find component providing 'mimetype::application/vnd.sketchup.skp'.
+%
+</pre></blockquote></p>
+
+<p>Yesterday I used it to figure out which packages support the STL 3D
+format:</p>
+
+<p><blockquote><pre>
+% appstreamcli what-provides mimetype  application/sla|grep Package
+Package: cura
+Package: meshlab
+Package: printrun
+%
+</pre></blockquote></p>
+
+<p>PS: A new version of Cura was uploaded to Debian yesterday.</p>

+      <div class="date"> 8th July 2018</div>
+      <div class="body"><p>Quite regularly, I let my Debian Sid/Unstable chroot stay untouch
+for a while, and when I need to update it there is not enough free
+space on the disk for apt to do a normal 'apt upgrade'.  I normally
+would resolve the issue by doing 'apt install &lt;somepackages&gt;' to
+upgrade only some of the packages in one batch, until the amount of
+packages to download fall below the amount of free space available.
+Today, I had about 500 packages to upgrade, and after a while I got
+tired of trying to install chunks of packages manually.  I concluded
+that I did not have the spare hours required to complete the task, and
+decided to see if I could automate it.  I came up with this small
+script which I call 'apt-in-chunks':</p>
+
+<p><blockquote><pre>
+#!/bin/sh
+#
+# Upgrade packages when the disk is too full to upgrade every
+# upgradable package in one lump.  Fetching packages to upgrade using
+# apt, and then installing using dpkg, to avoid changing the package
+# flag for manual/automatic.
+
+set -e
+
+ignore() {
+    if [ "$1" ]; then
+       grep -v "$1"
+    else
+       cat
+    fi
+}
+
+for p in $(apt list --upgradable | ignore "$@" |cut -d/ -f1 | grep -v '^Listing...'); do
+    echo "Upgrading $p"
+    apt clean
+    apt install --download-only -y $p
+    for f in /var/cache/apt/archives/*.deb; do
+       if [ -e "$f" ]; then
+           dpkg -i /var/cache/apt/archives/*.deb
+           break
+       fi
+    done
+done
+</pre></blockquote></p>
+
+<p>The script will extract the list of packages to upgrade, try to
+download the packages needed to upgrade one package, install the
+downloaded packages using dpkg.  The idea is to upgrade packages
+without changing the APT mark for the package (ie the one recording of
+the package was manually requested or pulled in as a dependency).  To
+use it, simply run it as root from the command line.  If it fail, try
+'apt install -f' to clean up the mess and run the script again.  This
+might happen if the new packages conflict with one of the old
+packages.  dpkg is unable to remove, while apt can do this.</p>
+
+<p>It take one option, a package to ignore in the list of packages to
+upgrade.  The option to ignore a package is there to be able to skip
+the packages that are simply too large to unpack.  Today this was
+'ghc', but I have run into other large packages causing similar
+problems earlier (like TeX).</p>
+
+<p>Update 2018-07-08: Thanks to Paul Wise, I am aware of two
+alternative ways to handle this.  The "unattended-upgrades
+--minimal-upgrade-steps" option will try to calculate upgrade sets for
+each package to upgrade, and then upgrade them in order, smallest set
+first.  It might be a better option than my above mentioned script.
+Also, "aptutude upgrade" can upgrade single packages, thus avoiding
+the need for using "dpkg -i" in the script above.</p>

+      <div class="body"><p>So far, at least hydro-electric power, coal power, wind power,

+had never heard of stone power.  Then I learn about a quarry in a
+mountain in
+<a href="https://en.wikipedia.org/wiki/Bremanger">Bremanger</a> i
+Norway, where
+<a href="https://www.bontrup.com/en/activities/raw-materials/bremanger-quarry/">the
+Bremanger Quarry</a> company is extracting stone and dumping the stone
+into a shaft leading to its shipping harbour.  This downward movement
+in this shaft is used to produce electricity.  In short, it is using
+falling rocks instead of falling water to produce electricity, and
+according to its own statements it is producing more power than it is
+using, and selling the surplus electricity to the Norwegian power
+grid.  I find the concept truly amazing.  Is this the worlds only
+stone power plant?</p>

+      <div class="date">26th June 2018</div>
+      <div class="body"><p>My movie playing setup involve <a href="https://kodi.tv/">Kodi</a>,
+<a href="https://openelec.tv">OpenELEC</a> (probably soon to be
+replaced with <a href="https://libreelec.tv/">LibreELEC</a>) and an
+Infocus IN76 video projector.  My projector can be controlled via both
+a infrared remote controller, and a RS-232 serial line.  The vendor of
+my projector, <a href="https://www.infocus.com/">InFocus</a>, had been
+sensible enough to document the serial protocol in its user manual, so
+it is easily available, and I used it some years ago to write
+<a href="https://github.com/petterreinholdtsen/infocus-projector-control">a
+small script to control the projector</a>.  For a while now, I longed
+for a setup where the projector was controlled by Kodi, for example in
+such a way that when the screen saver went on, the projector was
+turned off, and when the screen saver exited, the projector was turned
+on again.</p>
+
+<p>A few days ago, with very good help from parts of my family, I
+managed to find a Kodi Add-on for controlling a Epson projector, and
+got in touch with its author to see if we could join forces and make a
+Add-on with support for several projectors.  To my pleasure, he was
+positive to the idea, and we set out to add InFocus support to his
+add-on, and make the add-on suitable for the official Kodi add-on
+repository.</p>
+
+<p>The Add-on is now working (for me, at least), with a few minor
+adjustments.  The most important change I do relative to the master
+branch in the github repository is embedding the
+<a href="https://github.com/pyserial/pyserial">pyserial module</a> in
+the add-on.  The long term solution is to make a "script" type
+pyserial module for Kodi, that can be pulled in as a dependency in
+Kodi.  But until that in place, I embed it.</p>
+
+<p>The add-on can be configured to turn on the projector when Kodi
+starts, off when Kodi stops as well as turn the projector off when the
+screensaver start and on when the screesaver stops.  It can also be
+told to set the projector source when turning on the projector.
+
+<p>If this sound interesting to you, check out
+<a href="https://github.com/fredrik-eriksson/kodi_projcontrol">the
+project github repository</a>.  Perhaps you can send patches to
+support your projector too?  As soon as we find time to wrap up the
+latest changes, it should be available for easy installation using any
+Kodi instance.</p>
+
+<p>For future improvements, I would like to add projector model
+detection and the ability to adjust the brightness level of the
+projector from within Kodi.  We also need to figure out how to handle
+the cooling period of the projector.  My projector refuses to turn on
+for 60 seconds after it was turned off.  This is not handled well by
+the add-on at the moment.</p>

-<a href="https://savannah.nongnu.org/projects/sysvinit">The upstream

-source was available from Savannah via subversion.  I am happy to
-report that this just changed.</p>
-
-<p>The upstream source is now in Git, and consist of three

-      <div class="date">14th February 2018</div>
-      <div class="body"><p>A few days ago, a new major version of
-<a href="https://www.videolan.org/">VLC</a> was announced, and I
-decided to check out if it now supported streaming over
-<a href="http://bittorrent.org/">bittorrent</a> and
-<a href="https://webtorrent.io">webtorrent</a>.  Bittorrent is one of
-the most efficient ways to distribute large files on the Internet, and
-Webtorrent is a variant of Bittorrent using
-<a href="https://webrtc.org">WebRTC</a> as its transport channel,
-allowing web pages to stream and share files using the same technique.
-The network protocols are similar but not identical, so a client
-supporting one of them can not talk to a client supporting the other.
-I was a bit surprised with what I discovered when I started to look.
-Looking at
-<a href="https://www.videolan.org/vlc/releases/3.0.0.html">the release
-notes</a> did not help answering this question, so I started searching
-the web.  I found several news articles from 2013, most of them
-tracing the news from Torrentfreak
-("<a href=https://torrentfreak.com/open-source-giant-vlc-mulls-bittorrent-support-130211/">Open
-Source Giant VLC Mulls BitTorrent Streaming Support</a>"), about a
-initiative to pay someone to create a VLC patch for bittorrent
-support.  To figure out what happend with this initiative, I headed
-over to the #videolan IRC channel and asked if there were some bug or
-feature request tickets tracking such feature.  I got an answer from
-lead developer Jean-Babtiste Kempf, telling me that there was a patch
-but neither he nor anyone else knew where it was.  So I searched a bit
-more, and came across an independent
-<a href="https://github.com/johang/vlc-bittorrent">VLC plugin to add
-bittorrent support</a>, created by Johan Gunnarsson in 2016/2017.
-Again according to Jean-Babtiste, this is not the patch he was talking
-about.</p>
-
-<p>Anyway, to test the plugin, I made a working Debian package from
-the git repository, with some modifications.  After installing this
-package, I could stream videos from
-<a href="https://www.archive.org/">The Internet Archive</a> using VLC
-commands like this:</p>
-
-<p><blockquote><pre>
-vlc https://archive.org/download/LoveNest/LoveNest_archive.torrent
-</pre></blockquote></p>
-
-<p>The plugin is supposed to handle magnet links too, but since The
-Internet Archive do not have magnet links and I did not want to spend
-time tracking down another source, I have not tested it.  It can take
-quite a while before the video start playing without any indication of
-what is going on from VLC.  It took 10-20 seconds when I measured it.
-Some times the plugin seem unable to find the correct video file to
-play, and show the metadata XML file name in the VLC status line.  I
-have no idea why.</p>
-
-<p>I have created a <a href="https://bugs.debian.org/890360">request for
-a new package in Debian (RFP)</a> and
-<a href="https://github.com/johang/vlc-bittorrent/issues/1">asked if
-the upstream author is willing to help make this happen</a>.  Now we
-wait to see what come out of this.  I do not want to maintain a
-package that is not maintained upstream, nor do I really have time to
-maintain more packages myself, so I might leave it at this.  But I
-really hope someone step up to do the packaging, and hope upstream is
-still maintaining the source.  If you want to help, please update the
-RFP request or the upstream issue.</p>
-
-<p>I have not found any traces of webtorrent support for VLC.</p>
