-               <description>&lt;p&gt;When I set out a few weeks ago to figure out
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/What_is_the_best_multimedia_player_in_Debian_.html&quot;&gt;which
-multimedia player in Debian claimed to support most file formats /
-MIME types&lt;/a&gt;, 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.&lt;/p&gt;
-
-&lt;p&gt;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
-&lt;a href=&quot;https://wiki.debian.org/DebianMultimedia/PlayerSupport&quot;&gt;Multimedia
-player MIME type support status&lt;/a&gt; Debian wiki page.&lt;/p&gt;
-
-&lt;p&gt;The new &quot;best&quot; 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.&lt;/p&gt;
-
-&lt;p&gt;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.&lt;/p&gt;

-               <description>&lt;p&gt;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 &amp;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&#39;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&#39;t.&lt;/p&gt;
-
-&lt;p&gt;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 &lt;tt&gt;file --mime-type&lt;/tt&gt;
-returning the application/ogg MIME type, which no video player I had
-installed listed as a MIME type they would understand.  I asked for
-&lt;a href=&quot;http://bugs.gw.com/view.php?id=382&quot;&gt;file to change its
-behavour&lt;/a&gt; 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.&lt;/p&gt;
-
-&lt;p&gt;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&#39;ve reported &lt;a href=&quot;http://bugs.debian.org/825993&quot;&gt;the
-rosegarden problem to BTS&lt;/a&gt; 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.&lt;/p&gt;
-
-&lt;p&gt;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
-&lt;tt&gt;file --mime-type&lt;/tt&gt; 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
-&lt;a href=&quot;https://www.freedesktop.org/wiki/Specifications/desktop-entry-spec/&quot;&gt;the
-desktop files&lt;/a&gt; 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 &#39;Open with&#39; or similar.  In general
-this work well.  But it depend on each program picking a good MIME
-type (preferably
-&lt;a href=&quot;http://www.iana.org/assignments/media-types/media-types.xhtml&quot;&gt;a
-MIME type registered with IANA&lt;/a&gt;), 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.&lt;/p&gt;
-
-&lt;p&gt;The &lt;tt&gt;/usr/share/mime/packages/rosegarden.xml&lt;/tt&gt; entry for
-&lt;a href=&quot;http://www.freedesktop.org/wiki/Specifications/shared-mime-info-spec&quot;&gt;the
-Shared MIME database&lt;/a&gt; look like this:&lt;/p&gt;

+                <pubDate>Wed, 7 Jun 2017 21:40:00 +0200</pubDate>
+               <description>&lt;p&gt;&lt;em&gt;This is a copy of
+&lt;a href=&quot;https://lists.nuug.no/pipermail/nikita-noark/2017-June/000297.html&quot;&gt;an
+email I posted to the nikita-noark mailing list&lt;/a&gt;.  Please follow up
+there if you would like to discuss this topic.  The background is that
+we are making a free software archive system based on the Norwegian
+&lt;a href=&quot;https://www.arkivverket.no/forvaltning-og-utvikling/regelverk-og-standarder/noark-standarden&quot;&gt;Noark
+5 standard&lt;/a&gt; for government archives.&lt;/em&gt;&lt;/p&gt;
+
+&lt;p&gt;I&#39;ve been wondering a bit lately how trusted timestamps could be
+stored in Noark 5.
+&lt;a href=&quot;https://en.wikipedia.org/wiki/Trusted_timestamping&quot;&gt;Trusted
+timestamps&lt;/a&gt; can be used to verify that some information
+(document/file/checksum/metadata) have not been changed since a
+specific time in the past.  This is useful to verify the integrity of
+the documents in the archive.&lt;/p&gt;
+
+&lt;p&gt;Then it occured to me, perhaps the trusted timestamps could be
+stored as dokument variants (ie dokumentobjekt referered to from
+dokumentbeskrivelse) with the filename set to the hash it is
+stamping?&lt;/p&gt;
+
+&lt;p&gt;Given a &quot;dokumentbeskrivelse&quot; with an associated &quot;dokumentobjekt&quot;,
+a new dokumentobjekt is associated with &quot;dokumentbeskrivelse&quot; with the
+same attributes as the stamped dokumentobjekt except these
+attributes:&lt;/p&gt;
+
+&lt;ul&gt;
+
+&lt;li&gt;format -&gt; &quot;RFC3161&quot;
+&lt;li&gt;mimeType -&gt; &quot;application/timestamp-reply&quot;
+&lt;li&gt;formatDetaljer -&gt; &quot;&amp;lt;source URL for timestamp service&amp;gt;&quot;
+&lt;li&gt;filenavn -&gt; &quot;&amp;lt;sjekksum&amp;gt;.tsr&quot;
+
+&lt;/ul&gt;
+
+&lt;p&gt;This assume a service following
+&lt;a href=&quot;https://tools.ietf.org/html/rfc3161&quot;&gt;IETF RFC 3161&lt;/a&gt; is
+used, which specifiy the given MIME type for replies and the .tsr file
+ending for the content of such trusted timestamp.  As far as I can
+tell from the Noark 5 specifications, it is OK to have several
+variants/renderings of a dokument attached to a given
+dokumentbeskrivelse objekt.  It might be stretching it a bit to make
+some of these variants represent crypto-signatures useful for
+verifying the document integrity instead of representing the dokument
+itself.&lt;/p&gt;
+
+&lt;p&gt;Using the source of the service in formatDetaljer allow several
+timestamping services to be used.  This is useful to spread the risk
+of key compromise over several organisations.  It would only be a
+problem to trust the timestamps if all of the organisations are
+compromised.&lt;/p&gt;
+
+&lt;p&gt;The following oneliner on Linux can be used to generate the tsr
+file.  $input is the path to the file to checksum, and $sha256 is the
+SHA-256 checksum of the file (ie the &quot;&lt;sjekksum&gt;.tsr&quot; value mentioned
+above).&lt;/p&gt;

 
 &lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
 
 &lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;

-&amp;lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&amp;gt;
-&amp;lt;mime-info xmlns=&quot;http://www.freedesktop.org/standards/shared-mime-info&quot;&amp;gt;
-  &amp;lt;mime-type type=&quot;audio/x-rosegarden&quot;&amp;gt;
-    &amp;lt;sub-class-of type=&quot;application/x-gzip&quot;/&amp;gt;
-    &amp;lt;comment&amp;gt;Rosegarden project file&amp;lt;/comment&amp;gt;
-    &amp;lt;glob pattern=&quot;*.rg&quot;/&amp;gt;
-  &amp;lt;/mime-type&amp;gt;
-&amp;lt;/mime-info&amp;gt;
+openssl ts -query -data &quot;$inputfile&quot; -cert -sha256 -no_nonce \
+  | curl -s -H &quot;Content-Type: application/timestamp-query&quot; \
+      --data-binary &quot;@-&quot; http://zeitstempel.dfn.de &gt; $sha256.tsr

 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
 
 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
 

-&lt;p&gt;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.&lt;/p&gt;
-
-&lt;p&gt;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:&lt;/p&gt;
+&lt;p&gt;To verify the timestamp, you first need to download the public key
+of the trusted timestamp service, for example using this command:&lt;/p&gt;

 
 &lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
 
 &lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;

-% 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
-%
+wget -O ca-cert.txt \
+  https://pki.pca.dfn.de/global-services-ca/pub/cacert/chain.txt

 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
 
 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
 

-&lt;p&gt;The fix was to add &quot;audio/x-rosegarden;&quot; at the end of the
-MimeType= line.&lt;/p&gt;
+&lt;p&gt;Note, the public key should be stored alongside the timestamps in
+the archive to make sure it is also available 100 years from now.  It
+is probably a good idea to standardise how and were to store such
+public keys, to make it easier to find for those trying to verify
+documents 100 or 1000 years from now. :)&lt;/p&gt;
+
+&lt;p&gt;The verification itself is a simple openssl command:&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+openssl ts -verify -data $inputfile -in $sha256.tsr \
+  -CAfile ca-cert.txt -text
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;

 
 

-&lt;p&gt;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
-&lt;tt&gt;file --mime-type&lt;/tt&gt; 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. :)&lt;/p&gt;
+&lt;p&gt;Is there any reason this approach would not work?  Is it somehow against
+the Noark 5 specification?&lt;/p&gt;

-               <description>&lt;p&gt;A little more than 11 years ago, one of the creators of Tor, and
-the current President of &lt;a href=&quot;https://www.torproject.org/&quot;&gt;the Tor
-project&lt;/a&gt;, Roger Dingledine, gave a talk for the members of the
-&lt;a href=&quot;http://www.nuug.no/&quot;&gt;Norwegian Unix User group&lt;/a&gt; (NUUG).  A
-video of the talk was recorded, and today, thanks to the great help
-from David Noble, I finally was able to publish the video of the talk
-on Frikanalen, the Norwegian open channel TV station where NUUG
-currently publishes its talks.  You can
-&lt;a href=&quot;http://frikanalen.no/se&quot;&gt;watch the live stream using a web
-browser&lt;/a&gt; with WebM support, or check out the recording on the video
-on demand page for the talk
-&quot;&lt;a href=&quot;http://beta.frikanalen.no/video/625599&quot;&gt;Tor: Anonymous
-communication for the US Department of Defence...and you.&lt;/a&gt;&quot;.&lt;/p&gt;
-
-&lt;p&gt;Here is the video included for those of you using browsers with
-HTML video and Ogg Theora support:&lt;/p&gt;
-
-&lt;p&gt;&lt;video width=&quot;70%&quot; poster=&quot;http://simula.gunkies.org/media/625599/large_thumb/20050421-tor-frikanalen.jpg&quot; controls&gt;

-&lt;/video&gt;&lt;/p&gt;
-
-&lt;p&gt;I guess the gist of the talk can be summarised quite simply: If you
-want to help the military in USA (and everyone else), use Tor. :)&lt;/p&gt;

+
+&lt;p&gt;Ord som ikke ble forstått er markert med stjerne (*), og trenger
+ekstra språksjekk.  Men ingen ord er forsvunnet, slik det var i

-                <pubDate>Wed, 25 May 2016 10:20:00 +0200</pubDate>
-               <description>&lt;p&gt;&lt;a href=&quot;https://tracker.debian.org/pkg/isenkram&quot;&gt;The isenkram
-system&lt;/a&gt; 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).&lt;/p&gt;
-
-&lt;p&gt;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
-&lt;a href=&quot;http://www.freedesktop.org/software/PackageKit/&quot;&gt;PackageKit&lt;/a&gt;,
-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&#39;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 &lt;tt&gt;isenkram&lt;/tt&gt; package and insert some hardware dongle
-and see if it is recognised.&lt;/p&gt;

-&lt;p&gt;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:&lt;/p&gt;
-
-&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
-% isenkram-lookup 
-bluez
-cheese
-fprintd
-fprintd-demo
-gkrellm-thinkbat
-hdapsd
-libpam-fprintd
-pidgin-blinklight
-thinkfan
-tleds
-tp-smapi-dkms
-tp-smapi-source
-tpb
-%p
-&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
-
-&lt;p&gt;The hardware mappings come from several places.  The preferred way
-is for packages to announce their hardware support using
-&lt;a href=&quot;https://www.freedesktop.org/software/appstream/docs/&quot;&gt;the

+               <description>&lt;p&gt;I disse dager, med frist 1. mai, har Riksarkivaren ute en høring på
+sin forskrift.  Som en kan se er det ikke mye tid igjen før fristen
+som går ut på søndag.  Denne forskriften er det som lister opp hvilke
+formater det er greit å arkivere i
+&lt;a href=&quot;http://www.arkivverket.no/arkivverket/Offentleg-forvalting/Noark/Noark-5&quot;&gt;Noark
+5-løsninger&lt;/a&gt; i Norge.&lt;/p&gt;
+
+&lt;p&gt;Jeg fant høringsdokumentene hos
+&lt;a href=&quot;https://www.arkivrad.no/aktuelt/riksarkivarens-forskrift-pa-horing&quot;&gt;Norsk
+Arkivråd&lt;/a&gt; etter å ha blitt tipset på epostlisten til
+&lt;a href=&quot;https://github.com/hiOA-ABI/nikita-noark5-core&quot;&gt;fri
+programvareprosjektet Nikita Noark5-Core&lt;/a&gt;, som lager et Noark 5
+Tjenestegresesnitt.  Jeg er involvert i Nikita-prosjektet og takket
+være min interesse for tjenestegrensesnittsprosjektet har jeg lest en
+god del Noark 5-relaterte dokumenter, og til min overraskelse oppdaget
+at standard epost ikke er på listen over godkjente formater som kan
+arkiveres.  Høringen med frist søndag er en glimrende mulighet til å
+forsøke å gjøre noe med det.  Jeg holder på med
+&lt;a href=&quot;https://github.com/petterreinholdtsen/noark5-tester/blob/master/docs/hoering-arkivforskrift.tex&quot;&gt;egen
+høringsuttalelse&lt;/a&gt;, og lurer på om andre er interessert i å støtte
+forslaget om å tillate arkivering av epost som epost i arkivet.&lt;/p&gt;
+
+&lt;p&gt;Er du igang med å skrive egen høringsuttalelse allerede?  I så fall
+kan du jo vurdere å ta med en formulering om epost-lagring. Jeg tror
+ikke det trengs så mye.  Her et kort forslag til tekst:&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;
+
+  &lt;p&gt;Viser til høring sendt ut 2017-02-17 (Riksarkivarens referanse
+  2016/9840 HELHJO), og tillater oss å sende inn noen innspill om
+  revisjon av Forskrift om utfyllende tekniske og arkivfaglige
+  bestemmelser om behandling av offentlige arkiver (Riksarkivarens
+  forskrift).&lt;/p&gt;
+
+  &lt;p&gt;Svært mye av vår kommuikasjon foregår i dag på e-post.  Vi
+  foreslår derfor at Internett-e-post, slik det er beskrevet i IETF
+  RFC 5322,
+  &lt;a href=&quot;https://tools.ietf.org/html/rfc5322&quot;&gt;https://tools.ietf.org/html/rfc5322&lt;/a&gt;. bør
+  inn som godkjent dokumentformat.  Vi foreslår at forskriftens
+  oversikt over godkjente dokumentformater ved innlevering i § 5-16
+  endres til å ta med Internett-e-post.&lt;/p&gt;
+
+&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;Som del av arbeidet med tjenestegrensesnitt har vi testet hvordan
+epost kan lagres i en Noark 5-struktur, og holder på å skrive et
+forslag om hvordan dette kan gjøres som vil bli sendt over til
+arkivverket så snart det er ferdig.  De som er interesserte kan
+&lt;a href=&quot;https://github.com/petterreinholdtsen/noark5-tester/blob/master/docs/epostlagring.md&quot;&gt;følge
+fremdriften på web&lt;/a&gt;.&lt;/p&gt;
+
+&lt;p&gt;Oppdatering 2017-04-28: I dag ble høringuttalelsen jeg skrev
+  &lt;a href=&quot;https://www.nuug.no/news/NUUGs_h_ringuttalelse_til_Riksarkivarens_forskrift.shtml&quot;&gt;sendt
+  inn av foreningen NUUG&lt;/a&gt;.&lt;/p&gt;

-               <link>http://people.skolelinux.org/pere/blog/Discharge_rate_estimate_in_new_battery_statistics_collector_for_Debian.html</link>
-               <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Discharge_rate_estimate_in_new_battery_statistics_collector_for_Debian.html</guid>
-                <pubDate>Mon, 23 May 2016 09:35:00 +0200</pubDate>
-               <description>&lt;p&gt;Yesterday I updated the
-&lt;a href=&quot;https://tracker.debian.org/pkg/battery-stats&quot;&gt;battery-stats
-package in Debian&lt;/a&gt; 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.&lt;/p&gt;
-
-&lt;p&gt;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.&lt;/p&gt;
-
-&lt;p align=&quot;center&quot;&gt;&lt;img src=&quot;http://people.skolelinux.org/pere/blog/images/2016-05-23-battery-stats-rate.png&quot;/&gt;&lt;/p&gt;
-
-&lt;p&gt;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:
-
-&lt;p align=&quot;center&quot;&gt;&lt;img src=&quot;http://people.skolelinux.org/pere/blog/images/2016-05-23-battery-stats-history.png&quot;/&gt;&lt;/p&gt;
-
-&lt;p&gt;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. :(&lt;/p&gt;
-
-&lt;p&gt;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.&lt;/p&gt;
-
-&lt;p&gt;If you are interested in how your laptop battery is doing, please
-check out the
-&lt;a href=&quot;https://tracker.debian.org/pkg/battery-stats&quot;&gt;battery-stats&lt;/a&gt;
-in Debian unstable, or rebuild it on Jessie to get it working on
-Debian stable. :) The upstream source is available from &lt;a
-href=&quot;https://github.com/petterreinholdtsen/battery-stats&quot;&gt;github&lt;/a&gt;.
-Patches are very welcome.&lt;/p&gt;
-
-&lt;p&gt;As usual, if you use Bitcoin and want to show your support of my
-activities, please send Bitcoin donations to my address
-&lt;b&gt;&lt;a href=&quot;bitcoin:15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&quot;&gt;15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&lt;/a&gt;&lt;/b&gt;.&lt;/p&gt;

+                <pubDate>Thu, 20 Apr 2017 13:00:00 +0200</pubDate>
+               <description>&lt;p&gt;Jeg oppdaget i dag at &lt;a href=&quot;https://www.oep.no/&quot;&gt;nettstedet som
+publiserer offentlige postjournaler fra statlige etater&lt;/a&gt;, OEP, har
+begynt å blokkerer enkelte typer webklienter fra å få tilgang.  Vet
+ikke hvor mange det gjelder, men det gjelder i hvert fall libwww-perl
+og curl.  For å teste selv, kjør følgende:&lt;/p&gt;
+
+&lt;blockquote&gt;&lt;pre&gt;
+% curl -v -s https://www.oep.no/pub/report.xhtml?reportId=3 2&gt;&amp;1 |grep &#39;&lt; HTTP&#39;
+&lt; HTTP/1.1 404 Not Found
+% curl -v -s --header &#39;User-Agent:Opera/12.0&#39; https://www.oep.no/pub/report.xhtml?reportId=3 2&gt;&amp;1 |grep &#39;&lt; HTTP&#39;
+&lt; HTTP/1.1 200 OK
+%
+&lt;/pre&gt;&lt;/blockquote&gt;
+
+&lt;p&gt;Her kan en se at tjenesten gir «404 Not Found» for curl i
+standardoppsettet, mens den gir «200 OK» hvis curl hevder å være Opera
+versjon 12.0.  Offentlig elektronisk postjournal startet blokkeringen
+2017-03-02.&lt;/p&gt;
+
+&lt;p&gt;Blokkeringen vil gjøre det litt vanskeligere å maskinelt hente
+informasjon fra oep.no.  Kan blokkeringen være gjort for å hindre
+automatisert innsamling av informasjon fra OEP, slik Pressens
+Offentlighetsutvalg gjorde for å dokumentere hvordan departementene
+hindrer innsyn i
+&lt;a href=&quot;http://presse.no/dette-mener-np/undergraver-offentlighetsloven/&quot;&gt;rapporten
+«Slik hindrer departementer innsyn» som ble publiserte i januar
+2017&lt;/a&gt;.  Det virker usannsynlig, da det jo er trivielt å bytte
+User-Agent til noe nytt.&lt;/p&gt;
+
+&lt;p&gt;Finnes det juridisk grunnlag for det offentlige å diskriminere
+webklienter slik det gjøres her?  Der tilgang gis eller ikke alt etter
+hva klienten sier at den heter?  Da OEP eies av DIFI og driftes av
+Basefarm, finnes det kanskje noen dokumenter sendt mellom disse to
+aktørene man kan be om innsyn i for å forstå hva som har skjedd.  Men
+&lt;a href=&quot;https://www.oep.no/search/result.html?period=dateRange&amp;fromDate=01.01.2016&amp;toDate=01.04.2017&amp;dateType=documentDate&amp;caseDescription=&amp;descType=both&amp;caseNumber=&amp;documentNumber=&amp;sender=basefarm&amp;senderType=both&amp;documentType=all&amp;legalAuthority=&amp;archiveCode=&amp;list2=196&amp;searchType=advanced&amp;Search=Search+in+records&quot;&gt;postjournalen
+til DIFI viser kun to dokumenter&lt;/a&gt; det siste året mellom DIFI og
+Basefarm.
+&lt;a href=&quot;https://www.mimesbronn.no/request/blokkering_av_tilgang_til_oep_fo&quot;&gt;Mimes brønn neste&lt;/a&gt;,
+tenker jeg.&lt;/p&gt;

-                <pubDate>Sat, 21 May 2016 10:50:00 +0200</pubDate>
-               <description>&lt;p&gt;A few weeks ago the French paperback edition of Lawrence Lessigs
-2004 book Cultura Libre was published.  Today I noticed that the book
-is now available from book stores.  You can now buy it from
-&lt;a href=&quot;http://www.amazon.com/Culture-Libre-French-Lawrence-Lessig/dp/8269018260&quot;&gt;Amazon&lt;/a&gt;
-($19.99),
-&lt;a href=&quot;http://www.barnesandnoble.com/w/culture-libre-lawrence-lessig/1123776705&quot;&gt;Barnes
-&amp; Noble&lt;/a&gt; ($?) and as always from
-&lt;a href=&quot;http://www.lulu.com/shop/lawrence-lessig/culture-libre/paperback/product-22645082.html&quot;&gt;Lulu.com&lt;/a&gt;
-($19.99).  The revenue is donated to the Creative Commons project.  If
-you buy from Lulu.com, they currently get $10.59, while if you buy
-from one of the book stores most of the revenue go to the book store
-and the Creative Commons project get much (not sure how much
-less).&lt;/p&gt;
-
-&lt;p&gt;I was a bit surprised to discover that there is a kindle edition
-sold by Amazon Digital Services LLC on Amazon.  Not quite sure how
-that edition was created, but if you want to download a electronic
-edition (PDF, EPUB, Mobi) generated from the same files used to create
-the paperback edition, they are
-&lt;a href=&quot;https://github.com/petterreinholdtsen/free-culture-lessig&quot;&gt;available
-from github&lt;/a&gt;.&lt;/p&gt;

+                <pubDate>Sun, 19 Mar 2017 08:00:00 +0100</pubDate>
+               <description>&lt;p&gt;The &lt;a href=&quot;https://github.com/hiOA-ABI/nikita-noark5-core&quot;&gt;Nikita
+Noark 5 core project&lt;/a&gt; is implementing the Norwegian standard for
+keeping an electronic archive of government documents.
+&lt;a href=&quot;http://www.arkivverket.no/arkivverket/Offentlig-forvaltning/Noark/Noark-5/English-version&quot;&gt;The
+Noark 5 standard&lt;/a&gt; document the requirement for data systems used by
+the archives in the Norwegian government, and the Noark 5 web interface
+specification document a REST web service for storing, searching and
+retrieving documents and metadata in such archive.  I&#39;ve been involved
+in the project since a few weeks before Christmas, when the Norwegian
+Unix User Group
+&lt;a href=&quot;https://www.nuug.no/news/NOARK5_kjerne_som_fri_programvare_f_r_epostliste_hos_NUUG.shtml&quot;&gt;announced
+it supported the project&lt;/a&gt;.  I believe this is an important project,
+and hope it can make it possible for the government archives in the
+future to use free software to keep the archives we citizens depend
+on.  But as I do not hold such archive myself, personally my first use
+case is to store and analyse public mail journal metadata published
+from the government.  I find it useful to have a clear use case in
+mind when developing, to make sure the system scratches one of my
+itches.&lt;/p&gt;
+
+&lt;p&gt;If you would like to help make sure there is a free software
+alternatives for the archives, please join our IRC channel
+(&lt;a href=&quot;irc://irc.freenode.net/%23nikita&quot;&quot;&gt;#nikita on
+irc.freenode.net&lt;/a&gt;) and
+&lt;a href=&quot;https://lists.nuug.no/mailman/listinfo/nikita-noark&quot;&gt;the
+project mailing list&lt;/a&gt;.&lt;/p&gt;
+
+&lt;p&gt;When I got involved, the web service could store metadata about
+documents.  But a few weeks ago, a new milestone was reached when it
+became possible to store full text documents too.  Yesterday, I
+completed an implementation of a command line tool
+&lt;tt&gt;archive-pdf&lt;/tt&gt; to upload a PDF file to the archive using this
+API.  The tool is very simple at the moment, and find existing
+&lt;a href=&quot;https://en.wikipedia.org/wiki/Fonds&quot;&gt;fonds&lt;/a&gt;, series and
+files while asking the user to select which one to use if more than
+one exist.  Once a file is identified, the PDF is associated with the
+file and uploaded, using the title extracted from the PDF itself.  The
+process is fairly similar to visiting the archive, opening a cabinet,
+locating a file and storing a piece of paper in the archive.  Here is
+a test run directly after populating the database with test data using
+our API tester:&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+~/src//noark5-tester$ ./archive-pdf mangelmelding/mangler.pdf
+using arkiv: Title of the test fonds created 2017-03-18T23:49:32.103446
+using arkivdel: Title of the test series created 2017-03-18T23:49:32.103446
+
+ 0 - Title of the test case file created 2017-03-18T23:49:32.103446
+ 1 - Title of the test file created 2017-03-18T23:49:32.103446
+Select which mappe you want (or search term): 0
+Uploading mangelmelding/mangler.pdf
+  PDF title: Mangler i spesifikasjonsdokumentet for NOARK 5 Tjenestegrensesnitt
+  File 2017/1: Title of the test case file created 2017-03-18T23:49:32.103446
+~/src//noark5-tester$
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;You can see here how the fonds (arkiv) and serie (arkivdel) only had
+one option, while the user need to choose which file (mappe) to use
+among the two created by the API tester.  The &lt;tt&gt;archive-pdf&lt;/tt&gt;
+tool can be found in the git repository for the API tester.&lt;/p&gt;
+
+&lt;p&gt;In the project, I have been mostly working on
+&lt;a href=&quot;https://github.com/petterreinholdtsen/noark5-tester&quot;&gt;the API
+tester&lt;/a&gt; so far, while getting to know the code base.  The API
+tester currently use
+&lt;a href=&quot;https://en.wikipedia.org/wiki/HATEOAS&quot;&gt;the HATEOAS links&lt;/a&gt;
+to traverse the entire exposed service API and verify that the exposed
+operations and objects match the specification, as well as trying to
+create objects holding metadata and uploading a simple XML file to
+store.  The tester has proved very useful for finding flaws in our
+implementation, as well as flaws in the reference site and the
+specification.&lt;/p&gt;
+
+&lt;p&gt;The test document I uploaded is a summary of all the specification
+defects we have collected so far while implementing the web service.
+There are several unclear and conflicting parts of the specification,
+and we have
+&lt;a href=&quot;https://github.com/petterreinholdtsen/noark5-tester/tree/master/mangelmelding&quot;&gt;started
+writing down&lt;/a&gt; the questions we get from implementing it.  We use a
+format inspired by how &lt;a href=&quot;http://www.opengroup.org/austin/&quot;&gt;The
+Austin Group&lt;/a&gt; collect defect reports for the POSIX standard with
+&lt;a href=&quot;http://www.opengroup.org/austin/mantis.html&quot;&gt;their
+instructions for the MANTIS defect tracker system&lt;/a&gt;, in lack of an official way to structure defect reports for Noark 5 (our first submitted defect report was a &lt;a href=&quot;https://github.com/petterreinholdtsen/noark5-tester/blob/master/mangelmelding/sendt/2017-03-15-mangel-prosess.md&quot;&gt;request for a procedure for submitting defect reports&lt;/a&gt; :).
+
+&lt;p&gt;The Nikita project is implemented using Java and Spring, and is
+fairly easy to get up and running using Docker containers for those
+that want to test the current code base.  The API tester is
+implemented in Python.&lt;/p&gt;

-               <description>&lt;p&gt;I just donated to the
-&lt;a href=&quot;http://www.nuug.no/dns-beslag-donasjon.shtml&quot;&gt;NUUG defence
-&quot;fond&quot;&lt;/a&gt; to fund the effort in Norway to get the seizure of the news
-site popcorn-time.no tested in court.  I hope everyone that agree with
-me will do the same.&lt;/p&gt;
-
-&lt;p&gt;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.&lt;/p&gt;
-
-&lt;p&gt;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
-&lt;a href=&quot;https://web.archive.org/web/*/http://popcorn-time.no&quot;&gt;the web
-site content on the Internet Archive&lt;/A&gt;, and only found news coverage
-about Popcorn Time, not any material published without the right
-holders permissions.&lt;/p&gt;

+                <pubDate>Thu, 9 Mar 2017 15:20:00 +0100</pubDate>
+               <description>&lt;p&gt;Over the years, administrating thousand of NFS mounting linux
+computers at the time, I often needed a way to detect if the machine
+was experiencing NFS hang.  If you try to use &lt;tt&gt;df&lt;/tt&gt; or look at a
+file or directory affected by the hang, the process (and possibly the
+shell) will hang too.  So you want to be able to detect this without
+risking the detection process getting stuck too.  It has not been
+obvious how to do this.  When the hang has lasted a while, it is
+possible to find messages like these in dmesg:&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;
+nfs: server nfsserver not responding, still trying
+&lt;br&gt;nfs: server nfsserver OK
+&lt;/blockquote&gt;&lt;/p&gt;
+  
+&lt;p&gt;It is hard to know if the hang is still going on, and it is hard to
+be sure looking in dmesg is going to work.  If there are lots of other
+messages in dmesg the lines might have rotated out of site before they
+are noticed.&lt;/p&gt;
+
+&lt;p&gt;While reading through the nfs client implementation in linux kernel
+code, I came across some statistics that seem to give a way to detect
+it.  The om_timeouts sunrpc value in the kernel will increase every
+time the above log entry is inserted into dmesg.  And after digging a
+bit further, I discovered that this value show up in
+/proc/self/mountstats on Linux.&lt;/p&gt;
+
+&lt;p&gt;The mountstats content seem to be shared between files using the
+same file system context, so it is enough to check one of the
+mountstats files to get the state of the mount point for the machine.
+I assume this will not show lazy umounted NFS points, nor NFS mount
+points in a different process context (ie with a different filesystem
+view), but that does not worry me.&lt;/p&gt;
+
+&lt;p&gt;The content for a NFS mount point look similar to this:&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;

+[...]
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;The key number to look at is the third number in the per-op list.
+It is the number of NFS timeouts experiences per file system
+operation.  Here 22 write timeouts and 5 access timeouts.  If these
+numbers are increasing, I believe the machine is experiencing NFS
+hang.  Unfortunately the timeout value do not start to increase right
+away.  The NFS operations need to time out first, and this can take a
+while.  The exact timeout value depend on the setup.  For example the
+defaults for TCP and UDP mount points are quite different, and the
+timeout value is affected by the soft, hard, timeo and retrans NFS
+mount options.&lt;/p&gt;
+
+&lt;p&gt;The only way I have been able to get working on Debian and RedHat
+Enterprise Linux for getting the timeout count is to peek in /proc/.
+But according to
+&lt;ahref=&quot;http://docs.oracle.com/cd/E19253-01/816-4555/netmonitor-12/index.html&quot;&gt;Solaris
+10 System Administration Guide: Network Services&lt;/a&gt;, the &#39;nfsstat -c&#39;
+command can be used to get these timeout values.  But this do not work
+on Linux, as far as I can tell.  I
+&lt;ahref=&quot;http://bugs.debian.org/857043&quot;&gt;asked Debian about this&lt;/a&gt;,
+but have not seen any replies yet.&lt;/p&gt;
+
+&lt;p&gt;Is there a better way to figure out if a Linux NFS client is
+experiencing NFS hangs?  Is there a way to detect which processes are
+affected?  Is there a way to get the NFS mount going quickly once the
+network problem causing the NFS hang has been cleared?  I would very
+much welcome some clues, as we regularly run into NFS hangs.&lt;/p&gt;

+               <description>&lt;p&gt;So the new president in the United States of America claim to be
+surprised to discover that he was wiretapped during the election
+before he was elected president.  He even claim this must be illegal.
+Well, doh, if it is one thing the confirmations from Snowden
+documented, it is that the entire population in USA is wiretapped, one
+way or another.  Of course the president candidates were wiretapped,
+alongside the senators, judges and the rest of the people in USA.&lt;/p&gt;
+
+&lt;p&gt;Next, the Federal Bureau of Investigation ask the Department of
+Justice to go public rejecting the claims that Donald Trump was
+wiretapped illegally.  I fail to see the relevance, given that I am
+sure the surveillance industry in USA believe they have all the legal
+backing they need to conduct mass surveillance on the entire
+world.&lt;/p&gt;
+
+&lt;p&gt;There is even the director of the FBI stating that he never saw an
+order requesting wiretapping of Donald Trump.  That is not very
+surprising, given how the FISA court work, with all its activity being
+secret.  Perhaps he only heard about it?&lt;/p&gt;
+
+&lt;p&gt;What I find most sad in this story is how Norwegian journalists
+present it.  In a news reports the other day in the radio from the
+Norwegian National broadcasting Company (NRK), I heard the journalist
+claim that &#39;the FBI denies any wiretapping&#39;, while the reality is that
+&#39;the FBI denies any illegal wiretapping&#39;.  There is a fundamental and
+important difference, and it make me sad that the journalists are
+unable to grasp it.&lt;/p&gt;

-               <description>&lt;p&gt;&lt;strong&gt;Where I set out to figure out which multimedia player in
-Debian claim support for most file formats.&lt;/strong&gt;&lt;/p&gt;
-
-&lt;p&gt;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.
-&lt;a href=&quot;https://wiki.debian.org/DebianEdu/BrowserMultimedia&quot;&gt;The
-result&lt;/a&gt; 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.&lt;/p&gt;
-
-&lt;p&gt;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
-&lt;a href=&quot;https://bugs.debian.org/822245&quot;&gt;missing MIME type in the VLC
-desktop file&lt;/a&gt;.  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.&lt;/p&gt;
-
-&lt;p&gt;The result can be seen on the Debian Wiki, as
-&lt;a href=&quot;https://wiki.debian.org/DebianMultimedia/PlayerSupport&quot;&gt;a
-table listing all MIME types supported by one of the packages included
-in the table&lt;/a&gt;, with the package supporting most MIME types being
-listed first in the table.&lt;/p&gt;
-
-&lt;/p&gt;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?&lt;/p&gt;

+                <pubDate>Wed, 1 Mar 2017 20:50:00 +0100</pubDate>
+               <description>&lt;p&gt;A few days ago I ordered a small batch of
+&lt;a href=&quot;http://altusmetrum.org/ChaosKey/&quot;&gt;the ChaosKey&lt;/a&gt;, a small
+USB dongle for generating entropy created by Bdale Garbee and Keith
+Packard.  Yesterday it arrived, and I am very happy to report that it
+work great!  According to its designers, to get it to work out of the
+box, you need the Linux kernel version 4.1 or later.  I tested on a
+Debian Stretch machine (kernel version 4.9), and there it worked just
+fine, increasing the available entropy very quickly.  I wrote a small
+test oneliner to test.  It first print the current entropy level,
+drain /dev/random, and then print the entropy level for five seconds.
+Here is the situation without the ChaosKey inserted:&lt;/p&gt;
+
+&lt;blockquote&gt;&lt;pre&gt;
+% cat /proc/sys/kernel/random/entropy_avail; \
+  dd bs=1M if=/dev/random of=/dev/null count=1; \
+  for n in $(seq 1 5); do \
+     cat /proc/sys/kernel/random/entropy_avail; \
+     sleep 1; \
+  done

+12
+17
+21
+%
+&lt;/pre&gt;&lt;/blockquote&gt;
+
+&lt;p&gt;The entropy level increases by 3-4 every second.  In such case any
+application requiring random bits (like a HTTPS enabled web server)
+will halt and wait for more entrpy.  And here is the situation with

+&lt;p&gt;Quite the difference. :) I bought a few more than I need, in case
+someone want to buy one here in Norway. :)&lt;/p&gt;

+&lt;p&gt;Update: The dongle was presented at Debconf last year.  You might
+find &lt;a href=&quot;https://debconf16.debconf.org/talks/94/&quot;&gt;the talk

+randomness is, if you are unable to spot it from the schema drawing
+available from the ChaosKey web site linked at the start of this blog

-               <description>A friend of mine made me aware of
-&lt;a href=&quot;https://pyra-handheld.com/boards/pages/pyra/&quot;&gt;The Pyra&lt;/a&gt;, a
-handheld computer which will be delivered with Debian preinstalled.  I
-would love to get one of those for my birthday. :)&lt;/p&gt;
-
-&lt;p&gt;The machine is a complete ARM-based PC with micro HDMI, SATA, USB
-plugs and many others connectors, and include a full keyboard and a 5&quot;
-LCD touch screen.  The 6000mAh battery is claimed to provide a whole
-day of battery life time, but I have not seen any independent tests
-confirming this.  The vendor is still collecting preorders, and the
-last I heard last night was that 22 more orders were needed before
-production started.&lt;/p&gt;
-
-&lt;p&gt;As far as I know, this is the first handheld preinstalled with
-Debian.  Please let me know if you know of any others.  Is it the
-first computer being sold with Debian preinstalled?&lt;/p&gt;

+               <description>&lt;p&gt;I just noticed
+&lt;a href=&quot;http://www.arkivrad.no/aktuelt/riksarkivarens-forskrift-pa-horing&quot;&gt;the
+new Norwegian proposal for archiving rules in the goverment&lt;/a&gt; list
+&lt;a href=&quot;http://www.ecma-international.org/publications/standards/Ecma-376.htm&quot;&gt;ECMA-376&lt;/a&gt;
+/ ISO/IEC 29500 (aka OOXML) as valid formats to put in long term
+storage.  Luckily such files will only be accepted based on
+pre-approval from the National Archive.  Allowing OOXML files to be
+used for long term storage might seem like a good idea as long as we
+forget that there are plenty of ways for a &quot;valid&quot; OOXML document to
+have content with no defined interpretation in the standard, which
+lead to a question and an idea.&lt;/p&gt;
+
+&lt;p&gt;Is there any tool to detect if a OOXML document depend on such
+undefined behaviour?  It would be useful for the National Archive (and
+anyone else interested in verifying that a document is well defined)
+to have such tool available when considering to approve the use of
+OOXML.  I&#39;m aware of the
+&lt;a href=&quot;https://github.com/arlm/officeotron/&quot;&gt;officeotron OOXML
+validator&lt;/a&gt;, but do not know how complete it is nor if it will
+report use of undefined behaviour.  Are there other similar tools
+available?  Please send me an email if you know of any such tool.&lt;/p&gt;
