-      <div class="body"><p>Two years ago, I had
-<a href="http://people.skolelinux.org/pere/blog/Public_Trusted_Timestamping_services_for_everyone.html">a
-look at trusted timestamping options available</a>, and among
-other things noted a still open
-<a href="https://bugs.debian.org/742553">bug in the tsget script</a>
-included in openssl that made it harder than necessary to use openssl
-as a trusted timestamping client.  A few days ago I was told
-<a href="https::/www.difi.no/">the Norwegian government office DIFI</a> is
-close to releasing their own trusted timestamp service, and in the
-process I was happy to learn about a replacement for the tsget script
-using only curl:</p>
-
-<p><pre>
-openssl ts -query -data "/etc/shells" -cert -sha256 -no_nonce \
-  | curl -s -H "Content-Type: application/timestamp-query" \
-         --data-binary "@-" http://zeitstempel.dfn.de > etc-shells.tsr
-openssl ts -reply -text -in etc-shells.tsr
-</pre></p>
-
-<p>This produces a binary timestamp file (etc-shells.tsr) which can be
-used to verify that the content of the file /etc/shell with the
-calculated sha256 hash existed at the point in time when the request
-was made.  The last command extract the content of the etc-shells.tsr
-in human readable form.  The idea behind such timestamp is to be able
-to prove using cryptography that the content of a file have not
-changed since the file was stamped.</p>
-
-<p>To verify that the file on disk match the public key signature in
-the timestamp file, run the following commands.  It make sure you have
-the required certificate for the trusted timestamp service available
-and use it to compare the file content with the timestamp.  In
-production, one should of course use a better method to verify the
-service certificate.</p>
-
-<p><pre>
-wget -O ca-cert.txt https://pki.pca.dfn.de/global-services-ca/pub/cacert/chain.txt
-openssl ts -verify -data /etc/shells -in etc-shells.tsr -CAfile ca-cert.txt -text
-</pre></p>
-
-<p>Wikipedia have a lot more information about
-<a href="https://en.wikipedia.org/wiki/Trusted_timestamping">trusted
-Timestamping</a> and
-<a href="https://en.wikipedia.org/wiki/Linked_timestamping">linked
-timestamping</a>, and there are several trusted timestamping services
-around, both as commercial services and as free and public services.
-Among the latter is
-<a href="https://www.pki.dfn.de/zeitstempeldienst/">the
-zeitstempel.dfn.de service</a> mentioned above and
-<a href="https://freetsa.org/">freetsa.org service</a> linked to from the
-wikipedia web site.  I believe the DIFI service should show up on
-https://tsa.difi.no, but it is not available to the public at the
-moment.  I hope this will change when it is into production.  The
-<a href="https://tools.ietf.org/html/rfc3161">RFC 3161</a> trusted
-timestamping protocol standard is even implemented in LibreOffice,
-Microsoft Office and Adobe Acrobat, making it possible to verify when
-a document was created.</p>
-
-<p>I would find it useful to be able to use such trusted timestamp
-service to make it possible to verify that my stored syslog files have
-not been tampered with.  This is not a new idea.  I found one example
-implemented on the Endian network appliances where
-<a href="http://help.endian.com/entries/21518508-Enabling-Timestamping-on-log-files-">the
-configuration of such feature was described in 2012</a>.</p>
-
-<p>But I could not find any free implementation of such feature when I
-searched, so I decided to try to
-<a href="https://github.com/petterreinholdtsen/syslog-trusted-timestamp">build
-a prototype named syslog-trusted-timestamp</a>.  My idea is to
-generate a timestamp of the old log files after they are rotated, and
-store the timestamp in the new log file just after rotation.  This
-will form a chain that would make it possible to see if any old log
-files are tampered with.  But syslog is bad at handling kilobytes of
-binary data, so I decided to base64 encode the timestamp and add an ID
-and line sequence numbers to the base64 data to make it possible to
-reassemble the timestamp file again.  To use it, simply run it like
-this:
-
-<p><pre>
-syslog-trusted-timestamp /path/to/list-of-log-files
-</pre></p>
-
-<p>This will send a timestamp from one or more timestamp services (not
-yet decided nor implemented) for each listed file to the syslog using
-logger(1).  To verify the timestamp, the same program is used with the
---verify option:</p>
-
-<p><pre>
-syslog-trusted-timestamp --verify /path/to/log-file /path/to/log-with-timestamp
-</pre></p>
-
-<p>The verification step is not yet well designed.  The current
-implementation depend on the file path being unique and unchanging,
-and this is not a solid assumption.  It also uses process number as
-timestamp ID, and this is bound to create ID collisions.  I hope to
-have time to come up with a better way to handle timestamp IDs and
-verification later.</p>
-
-<p>Please check out
-<a href="https://github.com/petterreinholdtsen/syslog-trusted-timestamp">the
-prototype for syslog-trusted-timestamp on github</a> and send
-suggestions and improvement, or let me know if there already exist a
-similar system for timestamping logs already to allow me to join
-forces with others with the same interest.</p>

+      <div class="date"> 6th June 2016</div>
+      <div class="body"><p>When I set out a few weeks ago to figure out
+<a href="http://people.skolelinux.org/pere/blog/What_is_the_best_multimedia_player_in_Debian_.html">which
+multimedia player in Debian claimed to support most file formats /
+MIME types</a>, I was a bit surprised how varied the sets of MIME types
+the various players claimed support for.  The range was from 55 to 130
+MIME types.  I suspect most media formats are supported by all
+players, but this is not really reflected in the MimeTypes values in
+their desktop files.  There are probably also some bogus MIME types
+listed, but it is hard to identify which one this is.</p>
+
+<p>Anyway, in the mean time I got in touch with upstream for some of
+the players suggesting to add more MIME types to their desktop files,
+and decided to spend some time myself improving the situation for my
+favorite media player VLC.  The fixes for VLC entered Debian unstable
+yesterday. The complete list of MIME types can be seen on the
+<a href="https://wiki.debian.org/DebianMultimedia/PlayerSupport">Multimedia
+player MIME type support status</a> Debian wiki page.</p>
+
+<p>The new "best" multimedia player in Debian?  It is VLC, followed by
+totem, parole, kplayer, gnome-mpv, mpv, smplayer, mplayer-gui and
+kmplayer.  I am sure some of the other players desktop files support
+several of the formats currently listed as working only with vlc,
+toten and parole.</p>
+
+<p>A sad observation is that only 14 MIME types are listed as
+supported by all the tested multimedia players in Debian in their
+desktop files: audio/mpeg, audio/vnd.rn-realaudio, audio/x-mpegurl,
+audio/x-ms-wma, audio/x-scpls, audio/x-wav, video/mp4, video/mpeg,
+video/quicktime, video/vnd.rn-realvideo, video/x-matroska,
+video/x-ms-asf, video/x-ms-wmv and video/x-msvideo.  Personally I find
+it sad that video/ogg and video/webm is not supported by all the media
+players in Debian.  As far as I can tell, all of them can handle both
+formats.</p>

-      <div class="body"><p>Since this morning, the battery-stats package in Debian include an
-extended collector that will collect the complete battery history for
-later processing and graphing.  The original collector store the
-battery level as percentage of last full level, while the new
-collector also record battery vendor, model, serial number, design
-full level, last full level and current battery level.  This make it
-possible to predict the lifetime of the battery as well as visualise
-the energy flow when the battery is charging or discharging.</p>
-
-<p>The new tools are available in <tt>/usr/share/battery-stats/</tt>
-in the version 0.5.1 package in unstable.  Get the new battery level graph
-and lifetime prediction by running:
-
-<p><pre>
-/usr/share/battery-stats/battery-stats-graph /var/log/battery-stats.csv
-</pre></p>
-
-<p>Or select the 'Battery Level Graph' from your application menu.</p>
-
-<p>The flow in/out of the battery can be seen by running (no menu
-entry yet):</p>
-
-<p><pre>
-/usr/share/battery-stats/battery-stats-graph-flow
-</pre></p>
-
-<p>I'm not quite happy with the way the data is visualised, at least
-when there are few data points.  The graphs look a bit better with a
-few years of data.</p>
-
-<p>A while back one important feature I use in the battery stats
-collector broke in Debian.  The scripts in
-<tt>/usr/lib/pm-utils/power.d/</tt> were no longer executed.  I
-suspect it happened when Jessie started using systemd, but I do not
-know.  The issue is reported as
-<a href="https://bugs.debian.org/818649">bug #818649</a> against
-pm-utils.  I managed to work around it by adding an udev rule to call
-the collector script every time the power connector is connected and
-disconnected.  With this fix in place it was finally time to make a
-new release of the package, and get it into Debian.</p>

+      <div class="body"><p>Many years ago, when koffice was fresh and with few users, I
+decided to test its presentation tool when making the slides for a
+talk I was giving for NUUG on Japhar, a free Java virtual machine.  I
+wrote the first draft of the slides, saved the result and went to bed
+the day before I would give the talk.  The next day I took a plane to
+the location where the meeting should take place, and on the plane I
+started up koffice again to polish the talk a bit, only to discover
+that kpresenter refused to load its own data file.  I cursed a bit and
+started making the slides again from memory, to have something to
+present when I arrived.  I tested that the saved files could be
+loaded, and the day seemed to be rescued.  I continued to polish the
+slides until I suddenly discovered that the saved file could no longer
+be loaded into kpresenter.  In the end I had to rewrite the slides
+three times, condensing the content until the talk became shorter and
+shorter.  After the talk I was able to pinpoint the problem &ndash;
+kpresenter wrote inline images in a way itself could not understand.
+Eventually that bug was fixed and kpresenter ended up being a great
+program to make slides.  The point I'm trying to make is that we
+expect a program to be able to load its own data files, and it is
+embarrassing to its developers if it can't.</p>
+
+<p>Did you ever experience a program failing to load its own data
+files from the desktop file browser?  It is not a uncommon problem.  A
+while back I discovered that the screencast recorder
+gtk-recordmydesktop would save an Ogg Theora video file the KDE file
+browser would refuse to open.  No video player claimed to understand
+such file.  I tracked down the cause being <tt>file --mime-type</tt>
+returning the application/ogg MIME type, which no video player I had
+installed listed as a MIME type they would understand.  I asked for
+<a href="http://bugs.gw.com/view.php?id=382">file to change its
+behavour</a> and use the MIME type video/ogg instead.  I also asked
+several video players to add video/ogg to their desktop files, to give
+the file browser an idea what to do about Ogg Theora files.  After a
+while, the desktop file browsers in Debian started to handle the
+output from gtk-recordmydesktop properly.</p>
+
+<p>But history repeats itself.  A few days ago I tested the music
+system Rosegarden again, and I discovered that the KDE and xfce file
+browsers did not know what to do with the Rosegarden project files
+(*.rg).  I've reported <a href="http://bugs.debian.org/825993">the
+rosegarden problem to BTS</a> and a fix is commited to git and will be
+included in the next upload.  To increase the chance of me remembering
+how to fix the problem next time some program fail to load its files
+from the file browser, here are some notes on how to fix it.</p>
+
+<p>The file browsers in Debian in general operates on MIME types.
+There are two sources for the MIME type of a given file.  The output from
+<tt>file --mime-type</tt> mentioned above, and the content of the
+shared MIME type registry (under /usr/share/mime/).  The file MIME
+type is mapped to programs supporting the MIME type, and this
+information is collected from
+<a href="https://www.freedesktop.org/wiki/Specifications/desktop-entry-spec/">the
+desktop files</a> available in /usr/share/applications/.  If there is
+one desktop file claiming support for the MIME type of the file, it is
+activated when asking to open a given file.  If there are more, one
+can normally select which one to use by right-clicking on the file and
+selecting the wanted one using 'Open with' or similar.  In general
+this work well.  But it depend on each program picking a good MIME
+type (preferably
+<a href="http://www.iana.org/assignments/media-types/media-types.xhtml">a
+MIME type registered with IANA</a>), file and/or the shared MIME
+registry recognizing the file and the desktop file to list the MIME
+type in its list of supported MIME types.</p>
+
+<p>The <tt>/usr/share/mime/packages/rosegarden.xml</tt> entry for
+<a href="http://www.freedesktop.org/wiki/Specifications/shared-mime-info-spec">the
+Shared MIME database</a> look like this:</p>
+
+<p><blockquote><pre>
+&lt;?xml version="1.0" encoding="UTF-8"?&gt;
+&lt;mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info"&gt;
+  &lt;mime-type type="audio/x-rosegarden"&gt;
+    &lt;sub-class-of type="application/x-gzip"/&gt;
+    &lt;comment&gt;Rosegarden project file&lt;/comment&gt;
+    &lt;glob pattern="*.rg"/&gt;
+  &lt;/mime-type&gt;
+&lt;/mime-info&gt;
+</pre></blockquote></p>
+
+<p>This states that audio/x-rosegarden is a kind of application/x-gzip
+(it is a gzipped XML file).  Note, it is much better to use an
+official MIME type registered with IANA than it is to make up ones own
+unofficial ones like the x-rosegarden type used by rosegarden.</p>
+
+<p>The desktop file of the rosegarden program failed to list
+audio/x-rosegarden in its list of supported MIME types, causing the
+file browsers to have no idea what to do with *.rg files:</p>
+
+<p><blockquote><pre>
+% grep Mime /usr/share/applications/rosegarden.desktop
+MimeType=audio/x-rosegarden-composition;audio/x-rosegarden-device;audio/x-rosegarden-project;audio/x-rosegarden-template;audio/midi;
+X-KDE-NativeMimeType=audio/x-rosegarden-composition
+%
+</pre></blockquote></p>
+
+<p>The fix was to add "audio/x-rosegarden;" at the end of the
+MimeType= line.</p>
+
+<p>If you run into a file which fail to open the correct program when
+selected from the file browser, please check out the output from
+<tt>file --mime-type</tt> for the file, ensure the file ending and
+MIME type is registered somewhere under /usr/share/mime/ and check
+that some desktop file under /usr/share/applications/ is claiming
+support for this MIME type.  If not, please report a bug to have it
+fixed. :)</p>

-<a href="http://people.skolelinux.org/pere/blog/_Electronic__paper_invoices___using_vCard_in_a_QR_code.html">a
-way to make paper and PDF invoices easier to process electronically by
-adding a QR code with the key information about the invoice</a>.  I
-suggested using vCard field definition, to get some standard format
-for name and address, but any format would work.  I did not do

-
-<p>This was the background when I came across a proposal and
-specification from the web based accounting and invoicing supplier
-<a href="http://www.visma.com/">Visma</a> in Sweden called
-<a href="http://usingqr.com/">UsingQR</a>.  Their PDF invoices contain
-a QR code with the key information of the invoice in JSON format.
-This is the typical content of a QR code following the UsingQR
-specification (based on a real world example, some numbers replaced to
-get a more bogus entry).  I've reformatted the JSON to make it easier
-to read.  Normally this is all on one long line:</p>
-

-
-</p>The interpretation of the fields can be found in the
-<a href="http://usingqr.com/wp-content/uploads/2014/06/UsingQR_specification1.pdf">format
-specification</a> (revision 2 from june 2014).  The format seem to
-have most of the information needed to handle accounting and payment
-of invoices, at least the fields I have needed so far here in
-Norway.</p>
-
-<p>Unfortunately, the site and document do not mention anything about
-the patent, trademark and copyright status of the format and the
-specification.  Because of this, I asked the people behind it back in
-November to clarify.  Ann-Christine Savlid (ann-christine.savlid (at)
-visma.com) replied that Visma had not applied for patent or trademark
-protection for this format, and that there were no copyright based
-usage limitations for the format.  I urged her to make sure this was
-explicitly written on the web pages and in the specification, but
-unfortunately this has not happened yet.  So I guess if there is
-submarine patents, hidden trademarks or a will to sue for copyright
-infringements, those starting to use the UsingQR format might be at
-risk, but if this happen there is some legal defense in the fact that
-the people behind the format claimed it was safe to do so.  At least
-with patents, there is always
-<a href="http://www.paperspecs.com/paper-news/beware-the-qr-code-patent-trap/">a
-chance of getting sued...</a></p>
-
-<p>I also asked if they planned to maintain the format in an
-independent standard organization to give others more confidence that
-they would participate in the standardization process on equal terms
-with Visma, but they had no immediate plans for this.  Their plan was
-to work with banks to try to get more users of the format, and
-evaluate the way forward if the format proved to be popular.  I hope
-they conclude that using an open standard organisation like
-<a href="http://www.ietf.org/">IETF</a> is the correct place to
-maintain such specification.</p>
-
-<p><strong>Update 2016-03-20</strong>: Via Twitter I became aware of
-<a href="https://news.ycombinator.com/item?id=11319492">some comments
-about this blog post</a> that had several useful links and references to
-similar systems.  In the Czech republic, the Czech Banking Association

-information.  More information is available from the Wikipedia page on
-<a href="https://en.wikipedia.org/wiki/Short_Payment_Descriptor">Short

-(<a href="http://www.bezahlcode.de/wp-content/uploads/BezahlCode_TechDok.pdf">specification
-v1.8 2013-12-05 available as PDF</a>), which uses QR codes with

-provide the payment information.  There is also the
-<a href="http://www.ferd-net.de/front_content.php?idcat=231">ZUGFeRD</a>
-file format that perhaps could be transfered using QR codes, but I am
-not sure if it is done already.  Last, in Bolivia there are reports

-<a href="http://people.skolelinux.org/pere/blog/The_life_and_death_of_a_laptop_battery.html">the
-system I wrote to collect statistics about my laptop battery</a>, and
-how it showed the decay and death of this battery (now replaced).  I
-created a simple deb package to handle the collection and graphing,
-but did not want to upload it to Debian as there were already
-<a href="https://tracker.debian.org/pkg/battery-stats">a battery-stats
-package in Debian</a> that should do the same thing, and I did not see
-a point of uploading a competing package when battery-stats could be
-fixed instead.  I reported a few bugs about its non-function, and
-hoped someone would step in and fix it.  But no-one did.</p>
-
-<p>I got tired of waiting a few days ago, and took matters in my own
-hands.  The end result is that I am now the new upstream developer of
-battery stats (<a href="https://github.com/petterreinholdtsen/battery-stats">available from github</a>) and part of the team maintaining
-battery-stats in Debian, and the package in Debian unstable is finally
-able to collect battery status using the <tt>/sys/class/power_supply/</tt>
-information provided by the Linux kernel.  If you install the
-battery-stats package from unstable now, you will be able to get a
-graph of the current battery fill level, to get some idea about the
-status of the battery.  The source package build and work just fine in
-Debian testing and stable (and probably oldstable too, but I have not
-tested).  The default graph you get for that system look like this:</p>

-
-<p>My plans for the future is to merge my old scripts into the
-battery-stats package, as my old scripts collected a lot more details
-about the battery.  The scripts are merged into the upstream
-battery-stats git repository already, but I am not convinced they work
-yet, as I changed a lot of paths along the way.  Will have to test a
-bit more before I make a new release.</p>
-
-<p>I will also consider changing the file format slightly, as I
-suspect the way I combine several values into one field might make it
-impossible to know the type of the value when using it for processing
-and graphing.</p>
-
-<p>If you would like I would like to keep an close eye on your laptop

+      <div class="body"><p><a href="https://tracker.debian.org/pkg/isenkram">The isenkram
+system</a> is a user-focused solution in Debian for handling hardware
+related packages.  The idea is to have a database of mappings between
+hardware and packages, and pop up a dialog suggesting for the user to
+install the packages to use a given hardware dongle.  Some use cases
+are when you insert a Yubikey, it proposes to install the software
+needed to control it; when you insert a braille reader list it
+proposes to install the packages needed to send text to the reader;
+and when you insert a ColorHug screen calibrator it suggests to
+install the driver for it.  The system work well, and even have a few
+command line tools to install firmware packages and packages for the
+hardware already in the machine (as opposed to hotpluggable hardware).</p>
+
+<p>The system was initially written using aptdaemon, because I found
+good documentation and example code on how to use it.  But aptdaemon
+is going away and is generally being replaced by
+<a href="http://www.freedesktop.org/software/PackageKit/">PackageKit</a>,
+so Isenkram needed a rewrite.  And today, thanks to the great patch
+from my college Sunil Mohan Adapa in the FreedomBox project, the
+rewrite finally took place.  I've just uploaded a new version of
+Isenkram into Debian Unstable with the patch included, and the default
+for the background daemon is now to use PackageKit.  To check it out,
+install the <tt>isenkram</tt> package and insert some hardware dongle
+and see if it is recognised.</p>
+
+<p>If you want to know what kind of packages isenkram would propose for
+the machine it is running on, you can check out the isenkram-lookup
+program.  This is what it look like on a Thinkpad X230:</p>
+
+<p><blockquote><pre>
+% isenkram-lookup 
+bluez
+cheese
+fprintd
+fprintd-demo
+gkrellm-thinkbat
+hdapsd
+libpam-fprintd
+pidgin-blinklight
+thinkfan
+tleds
+tp-smapi-dkms
+tp-smapi-source
+tpb
+%p
+</pre></blockquote></p>
+
+<p>The hardware mappings come from several places.  The preferred way
+is for packages to announce their hardware support using
+<a href="https://www.freedesktop.org/software/appstream/docs/">the
+cross distribution appstream system</a>.
+See
+<a href="http://people.skolelinux.org/pere/blog/tags/isenkram/">previous
+blog posts about isenkram</a> to learn how to do that.</p>

-      <div class="date">19th February 2016</div>
-      <div class="body"><p>Making packages for Debian requires quite a lot of attention to
-details.  And one of the details is the content of the
-debian/copyright file, which should list all relevant licenses used by
-the code in the package in question, preferably in
-<a href="https://www.debian.org/doc/packaging-manuals/copyright-format/1.0/">machine
-readable DEP5 format</a>.</p>
-
-<p>For large packages with lots of contributors it is hard to write
-and update this file manually, and if you get some detail wrong, the
-package is normally rejected by the ftpmasters.  So getting it right
-the first time around get the package into Debian faster, and save
-both you and the ftpmasters some work..  Today, while trying to figure
-out what was wrong with
-<a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=686447">the
-zfsonlinux copyright file</a>, I decided to spend some time on
-figuring out the options for doing this job automatically, or at least
-semi-automatically.</p>
-
-<p>Lucikly, there are at least two tools available for generating the
-file based on the code in the source package,
-<tt><a href="https://tracker.debian.org/pkg/debmake">debmake</a></tt>
-and <tt><a href="https://tracker.debian.org/pkg/cme">cme</a></tt>.  I'm
-not sure which one of them came first, but both seem to be able to
-create a sensible draft file.  As far as I can tell, none of them can
-be trusted to get the result just right, so the content need to be
-polished a bit before the file is OK to upload.  I found the debmake
-option in
-<a href="http://goofying-with-debian.blogspot.com/2014/07/debmake-checking-source-against-dep-5.html">a
-blog posts from 2014</a>.
-
-<p>To generate using debmake, use the -cc option:
-
-<p><pre>
-debmake -cc > debian/copyright
-</pre></p>
-
-<p>Note there are some problems with python and non-ASCII names, so
-this might not be the best option.</p>
-
-<p>The cme option is based on a config parsing library, and I found
-this approach in
-<a href="https://ddumont.wordpress.com/2015/04/05/improving-creation-of-debian-copyright-file/">a
-blog post from 2015</a>.  To generate using cme, use the 'update
-dpkg-copyright' option:
-
-<p><pre>
-cme update dpkg-copyright
-</pre></p>
-
-<p>This will create or update debian/copyright.  The cme tool seem to
-handle UTF-8 names better than debmake.</p>
-
-<p>When the copyright file is created, I would also like some help to
-check if the file is correct.  For this I found two good options,
-<tt>debmake -k</tt> and <tt>license-reconcile</tt>.  The former seem
-to focus on license types and file matching, and is able to detect
-ineffective blocks in the copyright file.  The latter reports missing
-copyright holders and years, but was confused by inconsistent license
-names (like CDDL vs. CDDL-1.0).  I suspect it is good to use both and
-fix all issues reported by them before uploading.  But I do not know
-if the tools and the ftpmasters agree on what is important to fix in a
-copyright file, so the package might still be rejected.</p>
-
-<p>The devscripts tool <tt>licensecheck</tt> deserve mentioning.  It
-will read through the source and try to find all copyright statements.
-It is not comparing the result to the content of debian/copyright, but
-can be useful when verifying the content of the copyright file.</p>

+      <div class="body"><p>Yesterday I updated the
+<a href="https://tracker.debian.org/pkg/battery-stats">battery-stats
+package in Debian</a> with a few patches sent to me by skilled and
+enterprising users.  There were some nice user and visible changes.
+First of all, both desktop menu entries now work.  A design flaw in
+one of the script made the history graph fail to show up (its PNG was
+dumped in ~/.xsession-errors) if no controlling TTY was available.
+The script worked when called from the command line, but not when
+called from the desktop menu.  I changed this to look for a DISPLAY
+variable or a TTY before deciding where to draw the graph, and now the
+graph window pop up as expected.</p>
+
+<p>The next new feature is a discharge rate estimator in one of the
+graphs (the one showing the last few hours).  New is also the user of
+colours showing charging in blue and discharge in red.  The percentages
+of this graph is relative to last full charge, not battery design
+capacity.</p>
+
+<p align="center"><img src="http://people.skolelinux.org/pere/blog/images/2016-05-23-battery-stats-rate.png"/></p>
+
+<p>The other graph show the entire history of the collected battery
+statistics, comparing it to the design capacity of the battery to
+visualise how the battery life time get shorter over time.  The red
+line in this graph is what the previous graph considers 100 percent:
+
+<p align="center"><img src="http://people.skolelinux.org/pere/blog/images/2016-05-23-battery-stats-history.png"/></p>
+
+<p>In this graph you can see that I only charge the battery to 80
+percent of last full capacity, and how the capacity of the battery is
+shrinking. :(</p>
+
+<p>The last new feature is in the collector, which now will handle
+more hardware models.  On some hardware, Linux power supply
+information is stored in /sys/class/power_supply/ACAD/, while the
+collector previously only looked in /sys/class/power_supply/AC/.  Now
+both are checked to figure if there is power connected to the
+machine.</p>
+
+<p>If you are interested in how your laptop battery is doing, please
+check out the
+<a href="https://tracker.debian.org/pkg/battery-stats">battery-stats</a>
+in Debian unstable, or rebuild it on Jessie to get it working on
+Debian stable. :) The upstream source is available from <a
+href="https://github.com/petterreinholdtsen/battery-stats">github</a>.
+Patches are very welcome.</p>

-

-      <div class="date"> 4th February 2016</div>
-      <div class="body"><p>The <a href="https://wiki.debian.org/DEP-11">appstream system</a>
-is taking shape in Debian, and one provided feature is a very
-convenient way to tell you which package to install to make a given
-firmware file available when the kernel is looking for it.  This can
-be done using apt-file too, but that is for someone else to blog
-about. :)</p>
-
-<p>Here is a small recipe to find the package with a given firmware
-file, in this example I am looking for ctfw-3.2.3.0.bin, randomly
-picked from the set of firmware announced using appstream in Debian
-unstable.  In general you would be looking for the firmware requested
-by the kernel during kernel module loading.  To find the package
-providing the example file, do like this:</p>
-
-<blockquote><pre>
-% apt install appstream
-[...]
-% apt update
-[...]
-% appstreamcli what-provides firmware:runtime ctfw-3.2.3.0.bin | \
-  awk '/Package:/ {print $2}'
-firmware-qlogic
-%
-</pre></blockquote>
-
-<p>See <a href="https://wiki.debian.org/AppStream/Guidelines">the
-appstream wiki</a> page to learn how to embed the package metadata in
-a way appstream can use.</p>
-
-<p>This same approach can be used to find any package supporting a
-given MIME type.  This is very useful when you get a file you do not
-know how to handle.  First find the mime type using <tt>file
---mime-type</tt>, and next look up the package providing support for
-it.  Lets say you got an SVG file.  Its MIME type is image/svg+xml,
-and you can find all packages handling this type like this:</p>
-
-<blockquote><pre>
-% apt install appstream
-[...]
-% apt update
-[...]
-% appstreamcli what-provides mimetype image/svg+xml | \
-  awk '/Package:/ {print $2}'
-bkchem
-phototonic

-comix
-mirage
-viewnior
-postr
-ristretto
-kolourpaint4
-eog
-eom
-gimagereader
-midori
-%
-</pre></blockquote>
-
-<p>I believe the MIME types are fetched from the desktop file for

-with the computerised radio beacon known as a mobile phone their

-officials, company staff, those illegally buying information from

-public information can be collected and analysed, and a free software
-tool to do so is called
-<a href="http://www.geocreepy.com/">Creepy or Cree.py</a>.  I
-discovered it when I read
-<a href="http://www.aftenposten.no/kultur/Slik-kan-du-bli-overvaket-pa-Twitter-og-Instagram-uten-a-ane-det-7787884.html">an
-article about Creepy</a> in the Norwegian newspaper Aftenposten i
-November 2014, and decided to check if it was available in Debian.
-The python program was in Debian, but
-<a href="https://tracker.debian.org/pkg/creepy">the version in
-Debian</a> was completely broken and practically unmaintained.  I
-uploaded a new version which did not work quite right, but did not
-have time to fix it then.  This Christmas I decided to finally try to
-get Creepy operational in Debian.  Now a fixed version is available in
-Debian unstable and testing, and almost all Debian specific patches
-are now included
-<a href="https://github.com/jkakavas/creepy">upstream</a>.</p>
-
-<p>The Creepy program visualises geolocation information fetched from
-Twitter, Instagram, Flickr and Google+, and allow one to get a
-complete picture of every social media message posted recently in a
-given area, or track the movement of a given individual across all
-these services.  Earlier it was possible to use the search API of at
-least some of these services without identifying oneself, but these
-days it is impossible.  This mean that to use Creepy, you need to
-configure it to log in as yourself on these services, and provide
-information to them about your search interests.  This should be taken
-into account when using Creepy, as it will also share information
-about yourself with the services.</p>
-
-<p>The picture above show the twitter messages sent from (or at least
-geotagged with a position from) the city centre of Oslo, the capital
-of Norway.  One useful way to use Creepy is to first look at
-information tagged with an area of interest, and next look at all the

+
+<p>Would you be worried if you knew the police in your country could
+hijack DNS domains of news sites covering free software system without
+talking to a judge first?  I am.  What if the free software system
+combined search engine lookups, bittorrent downloads and video playout
+and was called Popcorn Time?  Would that affect your view?  It still
+make me worried.</p>
+
+<p>In March 2016, the Norwegian police seized (as in forced NORID to
+change the IP address pointed to by it to one controlled by the
+police) the DNS domain popcorn-time.no, without any supervision from
+the courts.  I did not know about the web site back then, and assumed
+the courts had been involved, and was very surprised when I discovered
+that the police had hijacked the DNS domain without asking a judge for
+permission first.  I was even more surprised when I had a look at
+<a href="https://web.archive.org/web/*/http://popcorn-time.no">the web
+site content on the Internet Archive</A>, and only found news coverage
+about Popcorn Time, not any material published without the right
+holders permissions.</p>
+
+<p>The seizure was widely covered in the Norwegian press (see for
+example <a href="http://www.hegnar.no/Nyheter/Naeringsliv/2016/03/Popcorn-time.no-beslaglagt-av-OEkokrim">Hegnar Online</a> and
+<a href="http://itavisen.no/2016/03/08/okokrim-har-beslaglagt-popcorn-time-no/">ITavisen<a/>
+and
+<a href="http://www.nrk.no/kultur/okokrim-gar-til-aksjon-mot-popcorn-time-1.12842452">NRK</a>),
+at first due to the press release sent out by Økokrim, but then based
+on
+<a href="http://blogg.torvund.net/2016/03/09/okokrims-beslag-i-domenet-popcorn-time-no/">protests
+from the law professor Olav Torvund</a> and
+<a href="http://www.klassekampen.no/article/20160311/ARTICLE/160319995">lawyer
+Jon Wessel-Aas</a>.  It even got some
+<a href="https://torrentfreak.com/norwegian-authorities-sued-over-popcorn-time-domain-seizure-160418/">coverage
+on TorrentFreak</a>.</p>
+
+<p>I
+<a href="http://people.skolelinux.org/pere/blog/NUUG_contests_Norwegian_police_DNS_seizure_of_popcorn_time_no.html">
+wrote about the case a month ago</a>, when the
+<a href="http://www.nuug.no/">Norwegian Unix User Group</a> (NUUG),
+where I am an active member, decided to ask the courts to test this seizure.
+The request was denied, but NUUG and its co-requestor EFN have not
+given up, and now they are rallying for support to get the seizure
+legally challenged.  They accept both bank and Bitcoin transfer for
+those that want to support the request.</p>
+
+<p>If you as me believe news sites about free software should not be
+censored, even if the free software have both legal and illegal
+applications, and that DNS hijacking should be tested by the courts, I
+suggest you <a href="http://www.nuug.no/dns-beslag-donasjon.shtml">show
+your support by donating to NUUG</a>.</a>

-      <div class="date">15th January 2016</div>
-      <div class="body"><p>During his DebConf15 keynote, Jacob Appelbaum
-<a href="https://summit.debconf.org/debconf15/meeting/331/what-is-to-be-done/">observed
-that those listening on the Internet lines would have good reason to
-believe a computer have a given security hole</a> if it download a
-security fix from a Debian mirror.  This is a good reason to always
-use encrypted connections to the Debian mirror, to make sure those
-listening do not know which IP address to attack.  In August, Richard
-Hartmann observed that encryption was not enough, when it was possible
-to interfere download size to security patches or the fact that
-download took place shortly after a security fix was released, and
-<a href="http://richardhartmann.de/blog/posts/2015/08/24-Tor-enabled_Debian_mirror/">proposed
-to always use Tor to download packages from the Debian mirror</a>.  He
-was not the first to propose this, as the
-<tt><a href="https://tracker.debian.org/pkg/apt-transport-tor">apt-transport-tor</a></tt>
-package by Tim Retout already existed to make it easy to convince apt
-to use <a href="https://www.torproject.org/">Tor</a>, but I was not
-aware of that package when I read the blog post from Richard.</p>
-
-<p>Richard discussed the idea with Peter Palfrader, one of the Debian
-sysadmins, and he set up a Tor hidden service on one of the central
-Debian mirrors using the address vwakviie2ienjx6t.onion, thus making
-it possible to download packages directly between two tor nodes,
-making sure the network traffic always were encrypted.</p>
-
-<p>Here is a short recipe for enabling this on your machine, by
-installing <tt>apt-transport-tor</tt> and replacing http and https
-urls with tor+http and tor+https, and using the hidden service instead
-of the official Debian mirror site.  I recommend installing
-<tt>etckeeper</tt> before you start to have a history of the changes
-done in /etc/.</p>
-
-<blockquote><pre>
-apt install apt-transport-tor
-sed -i 's% http://ftp.debian.org/% tor+http://vwakviie2ienjx6t.onion/%' /etc/apt/sources.list
-sed -i 's% http% tor+http%' /etc/apt/sources.list
-</pre></blockquote>
-
-<p>If you have more sources listed in /etc/apt/sources.list.d/, run
-the sed commands for these too.  The sed command is assuming your are
-using the ftp.debian.org Debian mirror.  Adjust the command (or just
-edit the file manually) to match your mirror.</p>
-
-<p>This work in Debian Jessie and later.  Note that tools like
-<tt>apt-file</tt> only recently started using the apt transport
-system, and do not work with these tor+http URLs.  For
-<tt>apt-file</tt> you need the version currently in experimental,
-which need a recent apt version currently only in unstable.  So if you
-need a working <tt>apt-file</tt>, this is not for you.</p>
-
-<p>Another advantage from this change is that your machine will start
-using Tor regularly and at fairly random intervals (every time you
-update the package lists or upgrade or install a new package), thus
-masking other Tor traffic done from the same machine.  Using Tor will
-become normal for the machine in question.</p>
-
-<p>On <a href="https://wiki.debian.org/FreedomBox">Freedombox</a>, APT
-is set up by default to use <tt>apt-transport-tor</tt> when Tor is
-enabled.  It would be great if it was the default on any Debian
-system.</p>

+      <div class="body"><p><strong>Where I set out to figure out which multimedia player in
+Debian claim support for most file formats.</strong></p>
+
+<p>A few years ago, I had a look at the media support for Browser
+plugins in Debian, to get an idea which plugins to include in Debian
+Edu.  I created a script to extract the set of supported MIME types
+for each plugin, and used this to find out which multimedia browser
+plugin supported most file formats / media types.
+<a href="https://wiki.debian.org/DebianEdu/BrowserMultimedia">The
+result</a> can still be seen on the Debian wiki, even though it have
+not been updated for a while.  But browser plugins are less relevant
+these days, so I thought it was time to look at standalone
+players.</p>
+
+<p>A few days ago I was tired of VLC not being listed as a viable
+player when I wanted to play videos from the Norwegian National
+Broadcasting Company, and decided to investigate why.  The cause is a
+<a href="https://bugs.debian.org/822245">missing MIME type in the VLC
+desktop file</a>.  In the process I wrote a script to compare the set
+of MIME types announced in the desktop file and the browser plugin,
+only to discover that there is quite a large difference between the
+two for VLC.  This discovery made me dig up the script I used to
+compare browser plugins, and adjust it to compare desktop files
+instead, to try to figure out which multimedia player in Debian
+support most file formats.</p>
+
+<p>The result can be seen on the Debian Wiki, as
+<a href="https://wiki.debian.org/DebianMultimedia/PlayerSupport">a
+table listing all MIME types supported by one of the packages included
+in the table</a>, with the package supporting most MIME types being
+listed first in the table.</p>
+
+</p>The best multimedia player in Debian?  It is totem, followed by
+parole, kplayer, mpv, vlc, smplayer mplayer-gui gnome-mpv and
+kmplayer.  Time for the other players to update their announced MIME
+support?</p>
