- <div class="body"><p><a href="http://www.coverity.com/">Coverity</a> is a nice tool to
-find problems in C, C++ and Java code using static source code
-analysis. It can detect a lot of different problems, and is very
-useful to find memory and locking bugs in the error handling part of
-the source. The company behind it provide
-<a href="https://scan.coverity.com/">check of free software projects as
-a community service</a>, and many hundred free software projects are
-already checked. A few days ago I decided to have a closer look at
-the Coverity system, and discovered that the
-<a href="http://www.gnu.org/software/gnash/">gnash</a> and
-<a href="http://sourceforge.net/projects/ipmitool/">ipmitool</a>
-projects I am involved with was already registered. But these are
-fairly big, and I would also like to have a small and easy project to
-check, and decided to <ahref="scan.coverity.com/projects/1179">request
-checking of the chrpath project</a>. It was
-added to the checker and discovered seven potential defects. Six of
-these were real, mostly resource "leak" when the program detected an
-error. Nothing serious, as the resources would be released a fraction
-of a second later when the program exited because of the error, but it
-is nice to do it right in case the source of the program some time in
-the future end up in a library. Having fixed all defects and added
-<a href="https://lists.alioth.debian.org/mailman/listinfo/chrpath-devel">a
-mailing list for the chrpath developers</a>, I decided it was time to
-publish a new release. These are the release notes:</p>

+ <div class="date">29th May 2014</div>
+ <div class="body"><p>Dear lazyweb. I'm planning to set up a small Raspberry Pi computer
+in my car, connected to
+<a href="http://www.dx.com/p/400a-4-0-tft-lcd-digital-monitor-for-vehicle-parking-reverse-camera-1440x272-12v-dc-57776">a
+small screen</a> next to the rear mirror. I plan to hook it up with a
+GPL and a USB wifi card too. The idea is to get my own
+"<a href="http://en.wikipedia.org/wiki/Carputer">Carputer</a>". But I
+wonder if someone already created a good free software solution for
+such car computer.</p>
+
+<p>This is my current wish list for such system:</p>
<ul>
- <li>Fixed all minor bugs discovered by Coverity.</li>
- <li>Updated config.sub and config.guess from the GNU project.</li>
- <li>Mention new project mailing list in the documentation.</li>
+ <li>Work on Raspberry Pi.</li>
+
+ <li>Show current speed limit based on location, and warn if going too
+ fast (for example using color codes yellow and red on the screen,
+ or make a sound). This could be done either using either data from
+ <a href="http://www.openstreetmap.org/">Openstreetmap</a> or OCR
+ info gathered from a dashboard camera.</li>
+
+ <li>Track automatic toll road passes and their cost, show total spent
+ and make it possible to calculate toll costs for planned
+ route.</li>
+
+ <li>Collect GPX tracks for use with OpenStreetMap.</li>
+
+ <li>Automatically detect and use any wireless connection to connect
+ to home server. Try IP over DNS
+ (<a href="http://dev.kryo.se/iodine/">iodine</a>) or ICMP
+ (<a href="http://code.gerade.org/hans/">Hans</a>) if direct
+ connection do not work.</li>
+
+ <li>Set up mesh network to talk to other cars with the same system,
+ or some stanard car mesh protocol.</li>
+
+ <li>Warn when approaching speed cameras and speed camera ranges
+ (speed calculated between two cameras).</li>
+
+ <li>Suport dashboard/front facing camera to discover speed limits and
+ run OCR to track registration number of passing cars.</li>
</ul>
-<p>You can
-<a href="https://alioth.debian.org/frs/?group_id=31052">download the
-new version 0.16 from alioth</a>. Please let us know via the Alioth
-project if something is wrong with the new release. The test suite
-did not discover any old errors, so if you find a new one, please also
-include a test suite check.</p>

- <div class="title"><a href="http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Dominik_George.html">Debian Edu interview: Dominik George</a></div>
- <div class="date">25th December 2013</div>
- <div class="body"><p>The <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux
-project</a> consist of both newcomers and old timers, and this time I
-was able to get an interview with a newcomer in the project who showed
-up on the IRC channel a few weeks ago to let us know about his
-successful installation of Debian Edu Wheezy in his School. Say hello
-to <a href="https://www.ohloh.net/accounts/Natureshadow">Dominik
-George</a>.</p>
-
-<!-- http://www.dominik-george.de/images/foto.jpg -->
-
-<p><strong>Who are you, and how do you spend your days?</strong></p>
-
-<p>I am a 23 year-old student from Germany who has spent half of his
-life with open source. In "real life", I am, as already mentioned, a
-student in the fields of Computer Science, Electrical Engineering,
-Information Technologies and Anglistics. Due to my (only partially
-voluntary) huge engagement in the open source world, these things are
-a bit vacant right now however.</p>
-
-<p>I also have been working as a project teacher at a Gymasnium
-(public school) for various years now. I took up that work some time
-around 2005 when still attending that school myself and have continued
-it until today. I also had been running the (kind of very advanced)
-network of that school together with a team of very interested and
-talented students in the age of 11 to 15 years, who took the chance to
-learn a lot about open source and networking before I left the school
-to help building another school's informational education concept from
-scratch.</p>
-
-<p>That said, one might see me as a kind of "glue" between school kids
-and the elderly of teachers as well as between the open source
-ecosystem and the (even more complex) educational ecosystem.</p>
-
-<p>When I am not busy with open source or education, I like Geocaching
-and cycling.</p>
-
-<p><strong>How did you get in contact with the Skolelinux / Debian Edu
-project?</strong></p>
-
-<p>I think that happened some time around 2009 when I first attended
-<a href="http://www.froscon.org">FrOSCon</a> and visited the project
-booth. I think I wasn't too interested back then because I used to
-have an attitude of disliking software that does too much stuff on its
-own. Maybe I was too inexperienced to realise the upsides of an
-"out-of-the-box" solution ;).</p>
-
-<p>The first time I actively talked to Skolelinux people was at
-<a href="http://www.openrheinruhr.de">OpenRheinRuhr</a> 2011 when the
-BiscuIT project, a home-grewn software used by my school for various
-really cool things from timetables and class contact lists to lunch
-ordering, student ID card printing and project elections first got to
-a stage where it could have been published. I asked the Skolelinux
-guys running the booth if the project were interested in it and gave a
-small demonstration, but there wasn't any real feedback and the guys
-seemed rather uninterested.</p>
-
-<p>After I left the school where I developed the software, it got
-mostly lost, but I am now reimplementing it for my new school. I have
-reusability and compatibility in mind, and I hop there will be a new
-basis for contributing it to the Skolelinux project ;)!</p>
-
-<p><strong>What do you see as the advantages of Skolelinux / Debian
-Edu?</strong></p>
-
-<p>The most important advantage seems to be that it "just
-works". After overcoming some minor (but still very annoying) glitches
-in the installer, I got a fully functional, working school network,
-without the month-long hassle I experienced when setting all that up
-from scratch in earlier years. And above that, it rocked - I didn't
-have any real hardware at hand, because the school was just founded
-and has no money whatsoever, so I installed a combined server (main
-server, terminal services and workstation) in a VM on my personal
-notebook, bridging the LTSP network interface to the ethernet port,
-and then PXE-booted the Windows notebooks that were lying around from
-it. I could use 8 clients without any performance issues, by using a
-tiny little VM on a tiny little notebook. I think that's enough to say
-that it rocks!</p>
-
-<p>Secondly, there are marketing reasons. Life's bad, and so no
-politician will ever permit a setup described as "Debian, an universal
-operating system, with some really cool educational tools" while they
-will be jsut fine with "Skolelinux, a single-purpose solution for your
-school network", even if both turn out to be the very same thing (yes,
-this is unfair towards the Skolelinux project, and must not be taken
-too seriously - you get the idea, anyway).</p>
-
-<p><strong>What do you see as the disadvantages of Skolelinux / Debian
-Edu?</strong></p>
-
-<p>I have not been involved with Skolelinux long enough to really
-answer this question in a fair way. Thus, please allow me to put it in
-other words: "What do you expect from Skolelinux to keep liking it?" I
-can list a few points about that:</p>
-
-<ul>
-
- <li>always strive to get all things integrated into Debian upstream
- <li>be open to discussion about changes and the like, even with newcomers
- <li>be helpful at being helpful ;)
-
-</ul>
-
-<p>I'm really sorry I cannot say much more about that :(!</p>
-
-<p><strong>Which free software do you use daily?</strong></p>
-
-<p>First of all, all software I use is free and open. I have abandoned
-all non-free software (except for firmware on my darned phone) this
-year.</p>
-
-<p>I run Debian GNU/Linux on all PC systems I use. On that, I mostly
-run text tools. I use
-<a href="https://www.mirbsd.org/mksh.htm">mksh</a> as shell,
-<a href="https://www.mirbsd.org/jupp.htm">jupp</a> as very advanced
-text editor (I even got the developer to help me write a script/macro
-based full-featured student management software with the two),
-<a href="http://mcabber.com/">mcabber</a> for XMPP and
-<a href="http://www.irssi.org/">irssi</a> for IRC. For that overly
-coloured world called the WWW, I use
-<a href="https://www.mozilla.org/en-US/firefox/new/">Iceweasel
-(Firefox)</a>. Oh, and <a href="http://www.mutt.org/">mutt</a> for
-e-mail.</p>
-
-<p>However, while I am personally aware of the fact that text tools
-are more efficient and powerful than anything else, I also use (or at
-least operate) some tools that are suitable to bring open source to
-kids. One of these things is <a href="http://jappix.org/">Jappix</a>,
-which I already introduced to some kids even before they got aware of
-Facebook, making them see for themselves that they do not need
-Facebook now ;).</p>
-
-<p><strong>Which strategy do you believe is the right one to use to
-get schools to use free software?</strong></p>
-
-<p>Well, that's a two-sided thing. One side is what I believe, and one
-side is what I have experienced.</p>
-
-<p>I believe that the right strategy is showing them the benefits. But
-that won't work out as long as the acceptance of free alternatives
-grows globally. What I mean is that if all the kids are almost forced
-to use Windows, Facebook, Skype, you name it at home, they will not
-see why they would want to use alternatives at school. I have seen
-students take seat in front of a fully-functional, modern Debian
-desktop that could do anything their Windows at home could do, and
-they jsut refused to use it because "Linux sucks". It is something
-that makes the council of our city spend around 600000 € to buy
-software - not including hardware, mind you - for operating school
-networks, and for installing a system that, as has been proved, does
-not work. For those of you readers who are good at maths, have you
-already found out how many lives could have been saved with that money
-if we had instead used it to bring education to parts of the world
-that need it? I have, and found it to be nothing less dramatic than
-plain criminal.</p>
-
-<p>That said, the only feasible way appears to be the bottom up
-method. We have to bring free software to kids and parents. I have
-founded an association named
-<a href="https://www.teckids.org">Teckids</a> here in Germany that does
-just that. We organise several events for kids and adolescents in the
-area of free and open source software, for example the
-<a href="http://kids.froscon.org">FrogLabs</a>, which share staff with
-Teckids and are the youth programme of
-<a href="http://www.froscon.org">the Free and Open Source Software
-Conference (FrOSCon)</a>. We do a lot more than most other conferences
-- this year, we first offered the FrogLabs as a holiday camp for kids
-aged 10 to 16. It was a huge success, with approx. 30 kids taking part
-and learning with and about free software through a whole weekend. All
-of us had a lot of fun, and the results were really exciting.</p>
-
-<p>Apart from that, we are preparing a campaign that is supposed to bring
-the message of free alternatives to stuff kids use every day to them and
-their parents, e.g. the use of Jabber / Jappix instead of Facebook and
-Skype. To make that possible, we are planning to get together a team of
-clever kids who understand very well what their peers need and can bring
-it across to them. So we will have a peer-driven network of adolescents
-who teach each other and collect feedback from the community of minors.
-We then take that feedback and our own experience to work closely with
-open source projects, such as Skolelinux or Jappix, at improving their
-software in a way that makes it more and more attractive for the target
-group. At least I hope that we will have good cooperation with
-Skolelinux in the future ;)!</p>
-
-<p>So in conclusion, what I believe is that, if it weren't for the world
-being so bad, it should be very clear to the political decision makers
-that the only way to go nowadays is free software for various reasons,
-but I have learnt that the only way that seems to work is bottom up.</p>
-
-<!--
-
-> * Who should be interviewed with this questions in the future?
-
-That's probably the hardest question of them all, as I do not know the
-community. However, I would be willing to do the following:
-
- <li>Run an interview with a German headteacher who is very open to
- free software, and also prefers it, but cannot really use it because
- of the decision makers above;
- <li>Run interviews with some kids, both with and without previous
- knowledge about free software
-
-If that is wanted, just let me know ;).

+ <div class="body"><p>I've been following <a href="http://www.getgnash.org/">the Gnash
+project</a> for quite a while now. It is a free software
+implementation of Adobe Flash, both a standalone player and a browser
+plugin. Gnash implement support for the AVM1 format (and not the
+newer AVM2 format - see
+<a href="http://lightspark.github.io/">Lightspark</a> for that one),
+allowing several flash based sites to work. Thanks to the friendly
+developers at Youtube, it also work with Youtube videos, because the
+Javascript code at Youtube detect Gnash and serve a AVM1 player to
+those users. :) Would be great if someone found time to implement AVM2
+support, but it has not happened yet. If you install both Lightspark
+and Gnash, Lightspark will invoke Gnash if it find a AVM1 flash file,
+so you can get both handled as free software. Unfortunately,
+Lightspark so far only implement a small subset of AVM2, and many
+sites do not work yet.</p>
+
+<p>A few months ago, I started looking at
+<a href="http://scan.coverity.com/">Coverity</a>, the static source
+checker used to find heaps and heaps of bugs in free software (thanks
+to the donation of a scanning service to free software projects by the
+company developing this non-free code checker), and Gnash was one of
+the projects I decided to check out. Coverity is able to find lock
+errors, memory errors, dead code and more. A few days ago they even
+extended it to also be able to find the heartbleed bug in OpenSSL.
+There are heaps of checks being done on the instrumented code, and the
+amount of bogus warnings is quite low compared to the other static
+code checkers I have tested over the years.</p>
+
+<p>Since a few weeks ago, I've been working with the other Gnash
+developers squashing bugs discovered by Coverity. I was quite happy
+today when I checked the current status and saw that of the 777 issues
+detected so far, 374 are marked as fixed. This make me confident that
+the next Gnash release will be more stable and more dependable than
+the previous one. Most of the reported issues were and are in the
+test suite, but it also found a few in the rest of the code.</p>
+
+<p>If you want to help out, you find us on
+<a href="https://lists.gnu.org/mailman/listinfo/gnash-dev">the
+gnash-dev mailing list</a> and on

-<a href="http://makerfaireoslo.no/no/program/dugnadsnett">Oslo Maker
-Faire</a>, og <a href="http://www.dugnadsnett.no/">Dugnadsnett for
-alle</a> har fått plass! Planen er å ha et bord med en plakat der vi
-forteller om hva Dugnadsnett for alle er for noe, og et lite verksted
-der vi hjelper folk som er interessert i å få opp sin egen mesh-node.
-Jeg gleder meg til å se hvordan prosjektet blir mottatt der.</p>
-
-<p>Målet med dugnadsnett for alle i Oslo er å få på plass et datanett
-for kommunikasjon ved hjelp av radio-repeaterstasjoner (kalt
-mesh-noder) som gjør at en kan direkte kommunisere med slekt, venner
-og bekjente i Oslo via andre som deltar i dugnadsnettet, samt gjøre
-det mulig komme ut på internett via dugnadsnettet. Første delmål er å
-kunne sende SMS-meldinger vha. IP-telefoni løsningen
-<a href="http://www.servalproject.org/">Serval project</a> mellom
-deltagerne i Dugnadsnett for alle i Oslo. Formålet er å ta tilbake
-kontrollen over egen nett-infrastruktur og gjøre det dyrere å bedrive
-massiv innsamling av informasjon om borgernes bruk av datanett.</p>
-
-<p>Høres dette interessant ut? Bli med på prosjektet, fortell oss
-hvor du kunne tenke deg å sette opp en radio-repeater (slik at folk i
-nærheten kan finne hverandre ved hjelp av
-<a href="http://flynor.net/mesh/mesh.php">kartet over planlagte og

+ <div class="date">23rd April 2014</div>
+ <div class="body"><p>It would be nice if it was easier in Debian to get all the hardware
+related packages relevant for the computer installed automatically.
+So I implemented one, using
+<a href="http://packages.qa.debian.org/isenkram">my Isenkram
+package</a>. To use it, install the tasksel and isenkram packages and
+run tasksel as user root. You should be presented with a new option,
+"Hardware specific packages (autodetected by isenkram)". When you
+select it, tasksel will install the packages isenkram claim is fit for
+the current hardware, hot pluggable or not.<p>
+
+<p>The implementation is in two files, one is the tasksel menu entry
+description, and the other is the script used to extract the list of
+packages to install. The first part is in
+<tt>/usr/share/tasksel/descs/isenkram.desc</tt> and look like
+this:</p>
+
+<p><blockquote><pre>
+Task: isenkram
+Section: hardware
+Description: Hardware specific packages (autodetected by isenkram)
+ Based on the detected hardware various hardware specific packages are
+ proposed.
+Test-new-install: mark show
+Relevance: 8
+Packages: for-current-hardware
+</pre></blockquote></p>
+
+<p>The second part is in
+<tt>/usr/lib/tasksel/packages/for-current-hardware</tt> and look like
+this:</p>
+
+<p><blockquote><pre>
+#!/bin/sh
+#
+(
+ isenkram-lookup
+ isenkram-autoinstall-firmware -l
+) | sort -u
+</pre></blockquote></p>
+
+<p>All in all, a very short and simple implementation making it
+trivial to install the hardware dependent package we all may want to
+have installed on our machines. I've not been able to find a way to
+get tasksel to tell you exactly which packages it plan to install
+before doing the installation. So if you are curious or careful,
+check the output from the isenkram-* command line tools first.</p>
+
+<p>The information about which packages are handling which hardware is
+fetched either from the isenkram package itself in
+/usr/share/isenkram/, from git.debian.org or from the APT package
+database (using the Modaliases header). The APT package database
+parsing have caused a nasty resource leak in the isenkram daemon (bugs
+<a href="http://bugs.debian.org/719837">#719837</a> and
+<a href="http://bugs.debian.org/730704">#730704</a>). The cause is in
+the python-apt code (bug
+<a href="http://bugs.debian.org/745487">#745487</a>), but using a
+workaround I was able to get rid of the file descriptor leak and
+reduce the memory leak from ~30 MiB per hardware detection down to
+around 2 MiB per hardware detection. It should make the desktop
+daemon a lot more useful. The fix is in version 0.7 uploaded to
+unstable today.</p>
+
+<p>I believe the current way of mapping hardware to packages in
+Isenkram is is a good draft, but in the future I expect isenkram to
+use the AppStream data source for this. A proposal for getting proper
+AppStream support into Debian is floating around as
+<a href="https://wiki.debian.org/DEP-11">DEP-11</a>, and
+<a href="https://wiki.debian.org/SummerOfCode2014/Projects#SummerOfCode2014.2FProjects.2FAppStreamDEP11Implementation.AppStream.2FDEP-11_for_the_Debian_Archive">GSoC
+project</a> will take place this summer to improve the situation. I
+look forward to seeing the result, and welcome patches for isenkram to
+start using the information when it is ready.</p>
+
+<p>If you want your package to map to some specific hardware, either
+add a "Xb-Modaliases" header to your control file like I did in
+<a href="http://packages.qa.debian.org/pymissile">the pymissile
+package</a> or submit a bug report with the details to the isenkram
+package. See also
+<a href="http://people.skolelinux.org/pere/blog/tags/isenkram/">all my
+blog posts tagged isenkram</a> for details on the notation. I expect
+the information will be migrated to AppStream eventually, but for the
+moment I got no better place to store it.</p>

+ <div class="body"><p>The <a href="https://wiki.debian.org/FreedomBox">Freedombox
+project</a> is working on providing the software and hardware to make
+it easy for non-technical people to host their data and communication
+at home, and being able to communicate with their friends and family
+encrypted and away from prying eyes. It is still going strong, and
+today a major mile stone was reached.</p>
+
+<p>Today, the last of the packages currently used by the project to
+created the system images were accepted into Debian Unstable. It was
+the freedombox-setup package, which is used to configure the images
+during build and on the first boot. Now all one need to get going is
+the build code from the freedom-maker git repository and packages from
+Debian. And once the freedombox-setup package enter testing, we can
+build everything directly from Debian. :)</p>
+
+<p>Some key packages used by Freedombox are
+<a href="http://packages.qa.debian.org/freedombox-setup">freedombox-setup</a>,
+<a href="http://packages.qa.debian.org/plinth">plinth</a>,

+are plans to integrate more packages into the setup. User
+documentation is maintained on the Debian wiki. Please
+<a href="https://wiki.debian.org/FreedomBox/Manual/Jessie">check out

+<p>To test for yourself and create boot images with the FreedomBox
+setup, run this on a Debian machine using a user with sudo rights to

-<p><strong>Who are you, and how do you spend your days?</strong></p>
-
-<p>I am Klaus Knopper. I have a master degree in electrical
-engineering, and is currently professor in information management at
-the university of applied sciences Kaiserslautern / Germany and
-freelance Open Source software developer and consultant.</p>
-
-<p>All of this is pretty much of the work I spend my days with. Apart
-from teaching, I'm also conducting some more or less experimental
-projects like the <a href="http://www.knoppix.org">Knoppix GNU/Linux live
-system</a> (Debian-based like Skolelinux),
-<a href="http://www.knopper.net/knoppix-adriane/index-en.html">ADRIANE</a>
-(a blind-friendly talking desktop system) and
-<a href="http://www.knopper.net/linbo/index-en.html">LINBO</a>
-(Linux-based network boot console, a fast remote install and repair
-system supporting various operating systems).</p>

+</pre></p>
-<p><strong>How did you get in contact with the Skolelinux / Debian Edu
-project?</strong></p>
+<p>Root access is needed to run debootstrap and mount loopback
+devices. See the README in the freedom-maker git repo for more
+details on the build. If you do not want all three images, trim the
+make line. Note that the virtualbox-image target is not really
+virtualbox specific. It create a x86 image usable in kvm, qemu,
+vmware and any other x86 virtual machine environment. You might need
+the version of vmdebootstrap in Jessie to get the build working, as it
+include fixes for a race condition with kpartx.</p>
-<p>The credit for this have to go to Kurt Gramlich, who is the German
-coordinator for Skolelinux. We were looking for an all-in-one open
-source community-supported distribution for schools, and Kurt
-introduced us to Skolelinux for this purpose.</p>
+<p>If you instead want to install using a Debian CD and the preseed
+method, boot a Debian Wheezy ISO and use this boot argument to load
+the preseed values:</p>
-<p><strong>What do you see as the advantages of Skolelinux / Debian
-Edu?</strong></p>
-
-<ul>
- <li>Quick installation,</li>
- <li>works (almost) out of the box,</li>
- <li>contains many useful software packages for teaching and learning,</li>
- <li>is a purely community-based distro and not controlled by a
- single company,</li>
- <li>has a large number of supporters and teachers who share their
- experience and problem solutions.</li>

-<p><strong>What do you see as the disadvantages of Skolelinux / Debian
-Edu?</strong></p>
+<p>I have not tested it myself the last few weeks, so I do not know if
+it still work.</p>
+
+<p>If you wonder how to help, one task you could look at is using
+systemd as the boot system. It will become the default for Linux in
+Jessie, so we need to make sure it is usable on the Freedombox. I did
+a simple test a few weeks ago, and noticed dnsmasq failed to start
+during boot when using systemd. I suspect there are other problems
+too. :) To detect problems, there is a test suite included, which can
+be run from the plinth web interface.</p>
+
+<p>Give it a go and let us know how it goes on the mailing list, and help
+us get the new release published. :) Please join us on
+<a href="irc://irc.debian.org:6667/%23freedombox">IRC (#freedombox on
+irc.debian.org)</a> and

+ <div class="date">11th April 2014</div>
+ <div class="body"><p>For 12 år siden, skrev jeg et lite notat om
+<a href="http://i18n.skolelinux.no/localekoder.txt">bruk av språkkoder
+i Norge</a>. Jeg ble nettopp minnet på dette da jeg fikk spørsmål om
+notatet fortsatt var aktuelt, og tenkte det var greit å repetere hva
+som fortsatt gjelder. Det jeg skrev da er fortsatt like aktuelt.</p>
+
+<p>Når en velger språk i programmer på unix, så velger en blant mange
+språkkoder. For språk i Norge anbefales følgende språkkoder (anbefalt
+locale i parantes):</p>
+
+<p><dl>
+<dt>nb (nb_NO)</dt><dd>Bokmål i Norge</dd>
+<dt>nn (nn_NO)</dt><dd>Nynorsk i Norge</dd>
+<dt>se (se_NO)</dt><dd>Nordsamisk i Norge</dd>
+</dl></p>
+
+<p>Alle programmer som bruker andre koder bør endres.</p>
+
+<p>Språkkoden bør brukes når .po-filer navngis og installeres. Dette
+er ikke det samme som locale-koden. For Norsk Bokmål, så bør filene
+være navngitt nb.po, mens locale (LANG) bør være nb_NO.</p>
+
+<p>Hvis vi ikke får standardisert de kodene i alle programmene med
+norske oversettelser, så er det umulig å gi LANG-variablen ett innhold
+som fungerer for alle programmer.</p>
+
+<p>Språkkodene er de offisielle kodene fra ISO 639, og bruken av dem i
+forbindelse med POSIX localer er standardisert i RFC 3066 og ISO
+15897. Denne anbefalingen er i tråd med de angitte standardene.</p>
+
+<p>Følgende koder er eller har vært i bruk som locale-verdier for
+"norske" språk. Disse bør unngås, og erstattes når de oppdages:</p>
+
+<p><table>
+<tr><td>norwegian</td><td>-> nb_NO</td></tr>
+<tr><td>bokmål </td><td>-> nb_NO</td></tr>
+<tr><td>bokmal </td><td>-> nb_NO</td></tr>
+<tr><td>nynorsk </td><td>-> nn_NO</td></tr>
+<tr><td>no </td><td>-> nb_NO</td></tr>
+<tr><td>no_NO </td><td>-> nb_NO</td></tr>
+<tr><td>no_NY </td><td>-> nn_NO</td></tr>
+<tr><td>sme_NO </td><td>-> se_NO</td></tr>
+</table></p>
+
+<p>Merk at når det gjelder de samiske språkene, at se_NO i praksis
+henviser til nordsamisk i Norge, mens f.eks. smj_NO henviser til
+lulesamisk. Dette notatet er dog ikke ment å gi råd rundt samiske
+språkkoder, der gjør

+ <div class="date"> 9th April 2014</div>
+ <div class="body"><p>For a while now, I have been looking for a sensible offsite backup
+solution for use at home. My requirements are simple, it must be
+cheap and locally encrypted (in other words, I keep the encryption
+keys, the storage provider do not have access to my private files).
+One idea me and my friends had many years ago, before the cloud
+storage providers showed up, was to use Google mail as storage,
+writing a Linux block device storing blocks as emails in the mail
+service provided by Google, and thus get heaps of free space. On top
+of this one can add encryption, RAID and volume management to have
+lots of (fairly slow, I admit that) cheap and encrypted storage. But
+I never found time to implement such system. But the last few weeks I
+have looked at a system called
+<a href="https://bitbucket.org/nikratio/s3ql/">S3QL</a>, a locally
+mounted network backed file system with the features I need.</p>
+
+<p>S3QL is a fuse file system with a local cache and cloud storage,
+handling several different storage providers, any with Amazon S3,
+Google Drive or OpenStack API. There are heaps of such storage
+providers. S3QL can also use a local directory as storage, which
+combined with sshfs allow for file storage on any ssh server. S3QL
+include support for encryption, compression, de-duplication, snapshots
+and immutable file systems, allowing me to mount the remote storage as
+a local mount point, look at and use the files as if they were local,
+while the content is stored in the cloud as well. This allow me to
+have a backup that should survive fire. The file system can not be
+shared between several machines at the same time, as only one can
+mount it at the time, but any machine with the encryption key and
+access to the storage service can mount it if it is unmounted.</p>
+
+<p>It is simple to use. I'm using it on Debian Wheezy, where the
+package is included already. So to get started, run <tt>apt-get
+install s3ql</tt>. Next, pick a storage provider. I ended up picking
+Greenqloud, after reading their nice recipe on
+<a href="https://greenqloud.zendesk.com/entries/44611757-How-To-Use-S3QL-to-mount-a-StorageQloud-bucket-on-Debian-Wheezy">how
+to use S3QL with their Amazon S3 service</a>, because I trust the laws
+in Iceland more than those in USA when it come to keeping my personal
+data safe and private, and thus would rather spend money on a company
+in Iceland. Another nice recipe is available from the article
+<a href="http://www.admin-magazine.com/HPC/Articles/HPC-Cloud-Storage">S3QL
+Filesystem for HPC Storage</a> by Jeff Layton in the HPC section of
+Admin magazine. When the provider is picked, figure out how to get
+the API key needed to connect to the storage API. With Greencloud,
+the key did not show up until I had added payment details to my
+account.</p>
+
+<p>Armed with the API access details, it is time to create the file
+system. First, create a new bucket in the cloud. This bucket is the
+file system storage area. I picked a bucket name reflecting the
+machine that was going to store data there, but any name will do.
+I'll refer to it as <tt>bucket-name</tt> below. In addition, one need
+the API login and password, and a locally created password. Store it
+all in ~root/.s3ql/authinfo2 like this:
+
+<p><blockquote><pre>
+[s3c]
+storage-url: s3c://s.greenqloud.com:443/bucket-name
+backend-login: API-login
+backend-password: API-password
+fs-passphrase: local-password
+</pre></blockquote></p>
+
+<p>I create my local passphrase using <tt>pwget 50</tt> or similar,
+but any sensible way to create a fairly random password should do it.
+Armed with these details, it is now time to run mkfs, entering the API
+details and password to create it:</p>
+
+<p><blockquote><pre>
+# mkdir -m 700 /var/lib/s3ql-cache
+# mkfs.s3ql --cachedir /var/lib/s3ql-cache --authfile /root/.s3ql/authinfo2 \
+ --ssl s3c://s.greenqloud.com:443/bucket-name
+Enter backend login:
+Enter backend password:
+Before using S3QL, make sure to read the user's guide, especially
+the 'Important Rules to Avoid Loosing Data' section.
+Enter encryption password:
+Confirm encryption password:

+Wrote 0.00 MB of compressed metadata.
+# </pre></blockquote></p>
+
+<p>The next step is mounting the file system to make the storage available.
+
+<p><blockquote><pre>
+# mount.s3ql --cachedir /var/lib/s3ql-cache --authfile /root/.s3ql/authinfo2 \
+ --ssl --allow-root s3c://s.greenqloud.com:443/bucket-name /s3ql

+Filesystem Size Used Avail Use% Mounted on
+s3c://s.greenqloud.com:443/bucket-name 1.0T 0 1.0T 0% /s3ql
+#
+</pre></blockquote></p>
+
+<p>The file system is now ready for use. I use rsync to store my
+backups in it, and as the metadata used by rsync is downloaded at
+mount time, no network traffic (and storage cost) is triggered by
+running rsync. To unmount, one should not use the normal umount
+command, as this will not flush the cache to the cloud storage, but
+instead running the umount.s3ql command like this:
+
+<p><blockquote><pre>
+# umount.s3ql /s3ql
+#
+</pre></blockquote></p>
+
+<p>There is a fsck command available to check the file system and
+correct any problems detected. This can be used if the local server
+crashes while the file system is mounted, to reset the "already
+mounted" flag. This is what it look like when processing a working
+file system:</p>
+
+<p><blockquote><pre>
+# fsck.s3ql --force --ssl s3c://s.greenqloud.com:443/bucket-name

+
+<p>Thanks to the cache, working on files that fit in the cache is very
+quick, about the same speed as local file access. Uploading large
+amount of data is to me limited by the bandwidth out of and into my
+house. Uploading 685 MiB with a 100 MiB cache gave me 305 kiB/s,
+which is very close to my upload speed, and downloading the same
+Debian installation ISO gave me 610 kiB/s, close to my download speed.
+Both were measured using <tt>dd</tt>. So for me, the bottleneck is my
+network, not the file system code. I do not know what a good cache
+size would be, but suspect that the cache should e larger than your
+working set.</p>
+
+<p>I mentioned that only one machine can mount the file system at the
+time. If another machine try, it is told that the file system is
+busy:</p>
+
+<p><blockquote><pre>
+# mount.s3ql --cachedir /var/lib/s3ql-cache --authfile /root/.s3ql/authinfo2 \
+ --ssl --allow-root s3c://s.greenqloud.com:443/bucket-name /s3ql
+Using 8 upload threads.
+Backend reports that fs is still mounted elsewhere, aborting.
+#
+</pre></blockquote></p>
+
+<p>The file content is uploaded when the cache is full, while the
+metadata is uploaded once every 24 hour by default. To ensure the
+file system content is flushed to the cloud, one can either umount the
+file system, or ask S3QL to flush the cache and metadata using
+s3qlctrl:
+
+<p><blockquote><pre>
+# s3qlctrl upload-meta /s3ql
+# s3qlctrl flushcache /s3ql
+#
+</pre></blockquote></p>
+
+<p>If you are curious about how much space your data uses in the
+cloud, and how much compression and deduplication cut down on the
+storage usage, you can use s3qlstat on the mounted file system to get
+a report:</p>
+
+<p><blockquote><pre>
+# s3qlstat /s3ql
+Directory entries: 9141
+Inodes: 9143
+Data blocks: 8851
+Total data size: 22049.38 MB
+After de-duplication: 21955.46 MB (99.57% of total)
+After compression: 21877.28 MB (99.22% of total, 99.64% of de-duplicated)
+Database size: 2.39 MB (uncompressed)
+(some values do not take into account not-yet-uploaded dirty blocks in cache)
+#
+</pre></blockquote></p>
+
+<p>I mentioned earlier that there are several possible suppliers of
+storage. I did not try to locate them all, but am aware of at least
+<a href="https://www.greenqloud.com/">Greenqloud</a>,
+<a href="http://drive.google.com/">Google Drive</a>,
+<a href="http://aws.amazon.com/s3/">Amazon S3 web serivces</a>,
+<a href="http://www.rackspace.com/">Rackspace</a> and
+<a href="http://crowncloud.net/">Crowncloud</A>. The latter even

+best.</p>
+
+<p>While researching this blog post, I had a look at research papers
+and posters discussing the S3QL file system. There are several, which
+told me that the file system is getting a critical check by the
+science community and increased my confidence in using it. One nice
+poster is titled
+"<a href="http://www.lanl.gov/orgs/adtsc/publications/science_highlights_2013/docs/pg68_69.pdf">An
+Innovative Parallel Cloud Storage System using OpenStack’s SwiftObject
+Store and Transformative Parallel I/O Approach</a>" by Hsing-Bung
+Chen, Benjamin McClelland, David Sherrill, Alfred Torrez, Parks Fields
+and Pamela Smith. Please have a look.</p>
+
+<p>Given my problems with different file systems earlier, I decided to
+check out the mounted S3QL file system to see if it would be usable as
+a home directory (in other word, that it provided POSIX semantics when
+it come to locking and umask handling etc). Running
+<a href="http://people.skolelinux.org/pere/blog/Testing_if_a_file_system_can_be_used_for_home_directories___.html">my
+test code to check file system semantics</a>, I was happy to discover that
+no error was found. So the file system can be used for home
+directories, if one chooses to do so.</p>
+
+<p>If you do not want a locally file system, and want something that
+work without the Linux fuse file system, I would like to mention the
+<a href="http://www.tarsnap.com/">Tarsnap service</a>, which also
+provide locally encrypted backup using a command line client. It have
+a nicer access control system, where one can split out read and write
+access, allowing some systems to write to the backup and others to
+only read from it.</p>
+
+<p>As usual, if you use Bitcoin and want to show your support of my
+activities, please send Bitcoin donations to my address

-<p>Prosjektledelsen har fortalt at dette skal fungere like godt for

-hadet det vært veldig fint om du kan send et leserbrev til
-<a href="http://www.uniforum.uio.no/">Uniforum</a> og fortelle om hvor
-greit det er å bruke Exchange i kryss-platform-miljøer? De jeg har
-snakket med sier en greit får lest e-posten sin hvis Exchange har

-fungerer godt for Linux-klienter. Jeg har ingen personlig erfaring å
-komme med, så jeg er nysgjerrig på hva andre kan dele av erfaringer
-med universitetet.</p>
-
-<p>Mitt ankerpunkt mot å bytte ut fri programvare som fungerer godt
-med godseid programvare er at en mister kontroll over egen
-infrastruktur, låser seg inn i en løsning det vil bli dyrt å komme ut
-av, uten at en får funksjonalitet en ikke kunne skaffet seg med fri
-programvare, eventuelt videreutviklet med de pengene som brukes på

- <div class="date">22nd November 2013</div>
- <div class="body"><p>I fjor sommer lagde jeg en
-<a href="http://people.skolelinux.org/pere/blog/SQL_database_med_anbud_publisert_p__Doffin.html">offentlig
-tilgjengelig SQL-database over offentlig anbud</a> basert på skraping
-av HTML-data fra Doffin. Den har stått og gått siden da, og har nå
-ca. 28000 oppføringer. Jeg oppdaget da jeg tittet innom at noen
-oppføringer var ikke blitt med, antagelig på grunn av at de fikk
-tildelt sekvensnummer i Doffin en godt stund før de ble publisert,
-slik at min nettsideskraper som fortsatte skrapingen der den slapp
-sist ikke fikk dem med seg. Jeg har fikset litt slik at skraperen nå
-ser litt tilbake i tid for å se om den har gått glipp av noen
-oppføringer, og har skrapet på nytt fra midten av september 2013 og
-fremover. Det bør dermed bli en mer komplett database for kommende
-måneder. Hvis jeg får tid skal jeg forsøke å skrape "glemte" data fra
-før midten av september 2013, men tør ikke garantere at det blir
-prioritert med det første. </p>
-
-<p>Men målet med denne bloggposten er å vise hvordan denne
-Doffin-databasen kan brukes og integreres med en RSS-leser, slik at en
-kan la datamaskinen holde et øye med Doffin-annonseringer etter
-nøkkelord. En kan lage sitt eget søk ved å besøke
-<ahref="https://classic.scraperwiki.com/docs/api?name=norwegian-doffin#sqlite">API-et
-hos Scraperwiki</a>, velge format rss2 og så legge inn noe ala dette i
-"query in SQL":</p>
-
-<p><pre>
-select title, scrapedurl as link, abstract as description,
- publishdate as pubDate from 'swdata'
- where abstract like '%linux%' or title like '%linux%'
- order by seq desc limit 20
-</pre></p>
-
-<p>Dette vil søke opp alle anbud med ordet linux i oppsummering eller
-tittel. En kan lage mer avanserte søk hvis en ønsker det. URL-en som
-dukker opp nederst på siden kan en så gi til sin RSS-leser (jeg bruker
-akregator selv), og så automatisk få beskjed hvis det dukker opp anbud
-med det aktuelle nøkkelordet i teksten. Merk at kapasiteten og
-ytelsen hos Scraperwiki er begrenset, så ikke be RSS-leseren hente ned
-oftere enn en gang hver dag.</p>
-
-<p>Du lurer kanskje på hva slags informasjon en kan få ut fra denne
-databasen. Her er to RSS-kilder, med søkeordet
-"<a href="https://api.scraperwiki.com/api/1.0/datastore/sqlite?format=rss2&name=norwegian-doffin&query=select%20title%2C%20scrapedurl%20as%20link%2C%20abstract%20as%20description%2C%0A%20%20%20%20%20%20%20publishdate%20as%20pubDate%20from%20'swdata'%0A%20%20%20where%20abstract%20like%20'%25linux%25'%20or%20title%20like%20'%25linux%25'%0A%20%20%20order%20by%20seq%20desc%20limit%2020">linux</a>",

+ <div class="date"> 1st April 2014</div>
+ <div class="body"><p>Microsoft have announced that Windows XP reaches its end of life
+2014-04-08, in 7 days. But there are heaps of machines still running
+Windows XP, and depending on Windows XP to run their applications, and
+upgrading will be expensive, both when it comes to money and when it
+comes to the amount of effort needed to migrate from Windows XP to a
+new operating system. Some obvious options (buy new a Windows
+machine, buy a MacOSX machine, install Linux on the existing machine)
+are already well known and covered elsewhere. Most of them involve
+leaving the user applications installed on Windows XP behind and
+trying out replacements or updated versions. In this blog post I want
+to mention one strange bird that allow people to keep the hardware and
+the existing Windows XP applications and run them on a free software
+operating system that is Windows XP compatible.</p>
+
+<p><a href="http://www.reactos.org/">ReactOS</a> is a free software
+operating system (GNU GPL licensed) working on providing a operating
+system that is binary compatible with Windows, able to run windows
+programs directly and to use Windows drivers for hardware directly.
+The project goal is for Windows user to keep their existing machines,
+drivers and software, and gain the advantages from user a operating
+system without usage limitations caused by non-free licensing. It is
+a Windows clone running directly on the hardware, so quite different
+from the approach taken by <a href="http://www.winehq.org/">the Wine
+project</a>, which make it possible to run Windows binaries on
+Linux.</p>
+
+<p>The ReactOS project share code with the Wine project, so most
+shared libraries available on Windows are already implemented already.
+There is also a software manager like the one we are used to on Linux,
+allowing the user to install free software applications with a simple
+click directly from the Internet. Check out the
+<a href="http://www.reactos.org/screenshots">screen shots on the
+project web site</a> for an idea what it look like (it looks just like
+Windows before metro).</p>
+
+<p>I do not use ReactOS myself, preferring Linux and Unix like
+operating systems. I've tested it, and it work fine in a virt-manager
+virtual machine. The browser, minesweeper, notepad etc is working
+fine as far as I can tell. Unfortunately, my main test application
+is the software included on a CD with the Lego Mindstorms NXT, which
+seem to install just fine from CD but fail to leave any binaries on
+the disk after the installation. So no luck with that test software.
+No idea why, but hope someone else figure out and fix the problem.
+I've tried the ReactOS Live ISO on a physical machine, and it seemed
+to work just fine. If you like Windows and want to keep running your
+old Windows binaries, check it out by
+<a href="http://www.reactos.org/download">downloading</a> the
+installation CD, the live CD or the preinstalled virtual machine
+image.</p>

- <div class="date">21st November 2013</div>
- <div class="body"><p>Drones, flying robots, are getting more and more popular. The most
-know ones are the killer drones used by some government to murder
-people they do not like without giving them the chance of a fair
-trial, but the technology have many good uses too, from mapping and
-forest maintenance to photography and search and rescue. I am sure it
-is just a question of time before "bad drones" are in the hands of
-private enterprises and not only state criminals but petty criminals
-too. The drone technology is very useful and very dangerous. To have
-some control over the use of drones, I agree with Daniel Suarez in his
-TED talk
-"<a href="https://archive.org/details/DanielSuarez_2013G">The kill
-decision shouldn't belong to a robot</a>", where he suggested this
-little gem to keep the good while limiting the bad use of drones:</p>
-
-<blockquote>
-
-<p>Each robot and drone should have a cryptographically signed
-I.D. burned in at the factory that can be used to track its movement
-through public spaces. We have license plates on cars, tail numbers on
-aircraft. This is no different. And every citizen should be able to
-download an app that shows the population of drones and autonomous
-vehicles moving through public spaces around them, both right now and
-historically. And civic leaders should deploy sensors and civic drones
-to detect rogue drones, and instead of sending killer drones of their
-own up to shoot them down, they should notify humans to their
-presence. And in certain very high-security areas, perhaps civic
-drones would snare them and drag them off to a bomb disposal facility.</p>
-
-<p>But notice, this is more an immune system than a weapons system. It
-would allow us to avail ourselves of the use of autonomous vehicles
-and drones while still preserving our open, civil society.</p>

-</blockquote>
-
-<p>The key is that <em>every citizen</em> should be able to read the
-radio beacons sent from the drones in the area, to be able to check
-both the government and others use of drones. For such control to be
-effective, everyone must be able to do it. What should such beacon
-contain? At least formal owner, purpose, contact information and GPS
-location. Probably also the origin and target position of the current
-flight. And perhaps some registration number to be able to look up
-the drone in a central database tracking their movement. Robots
-should not have privacy. It is people who need privacy.</p>

+ <div class="date">30th March 2014</div>
+ <div class="body"><p><a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a>
+keep gaining new users. Some weeks ago, a person showed up on IRC,
+<a href="irc://irc.debian.org/#debian-edu">#debian-edu</a>, with a
+wish to contribute, and I managed to get a interview with this great
+contributor Roger Marsal to learn more about his background.</p>
+
+<p><strong>Who are you, and how do you spend your days?</strong></p>
+
+<p>My name is Roger Marsal, I'm 27 years old (1986 generation) and I
+live in Barcelona, Spain. I've got a strong business background and I
+work as a patrimony manager and as a real estate agent. Additionally,
+I've co-founded a British based tech company that is nowadays on the
+last development phase of a new social networking concept.</p>
+
+<p>I'm a Linux enthusiast that started its journey with Ubuntu four years
+ago and have recently switched to Debian seeking rock solid stability
+and as a necessary step to gain expertise.</p>
+
+<p>In a nutshell, I spend my days working and learning as much as I
+can to face both my job, entrepreneur project and feed my Linux
+hunger.</p>
+
+<p><strong>How did you get in contact with the Skolelinux / Debian Edu
+project?</strong></p>
+
+<p>I discovered the <a href="http://www.ltsp.org/">LTSP</a> advantages
+with "Ubuntu 12.04 alternate install" and after a year of use I
+started looking for an alternative. Even though I highly value and
+respect the Ubuntu project, I thought it was necessary for me to
+change to a more robust and stable alternative. As far as I was using
+Debian on my personal laptop I thought it would be fine to install
+Debian and configure an LTSP server myself. Surprised, I discovered
+that the Debian project also supported a kind of Edubuntu equivalent,
+and after having some pain I obtained a Debian Edu network up and
+running. I just loved it.</p>
+
+<p><strong>What do you see as the advantages of Skolelinux / Debian
+Edu?</strong></p>
+
+<p>I found a main advantage in that, once you know "the tips and
+tricks", a new installation just works out of the box. It's the most
+complete alternative I've found to create an LTSP network. All the
+other distributions seems to be made of plastic, Debian Edu seems to
+be made of steel.</p>
+
+<p><strong>What do you see as the disadvantages of Skolelinux / Debian
+Edu?</strong></p>
+
+<p>I found two main disadvantages.</p>
+
+<p>I'm not an expert but I've got notions and I had to spent a considerable
+amount of time trying to bring up a standard network topology. I'm quite
+stubborn and I just worked until I did but I'm sure many people with few
+resources (not big schools, but academies for example) would have switched
+or dropped.</p>
+
+<p>It's amazing how such a complex system like Debian Edu has achieved
+this out-of-the-box state. Even though tweaking without breaking gets
+more difficult, as more factors have to be considered. This can
+discourage many people too.</p>
+
+<p><strong>Which free software do you use daily?</strong></p>
+
+<p>I use Debian, Firefox, Okular, Inkscape, LibreOffice and
+Virtualbox.</p>
+
+
+<p><strong>Which strategy do you believe is the right one to use to
+get schools to use free software?</strong></p>
+
+<p>I don't think there is a need for a particular strategy. The free
+attribute in both "freedom" and "no price" meanings is what will
+really bring free software to schools. In my experience I can think of
+the <a href="http://www.r-project.org/">"R" statistical language</a>; a
+few years a ago was an extremely nerd tool for university people.
+Today it's being increasingly used to teach statistics at many
+different level of studies. I believe free and open software will
+increasingly gain popularity, but I'm sure schools will be one of the
+first scenarios where this will happen.</p>

+ <div class="date">26th March 2014</div>
+ <div class="body"><p><a href="http://www.nuug.no/">Foreningen NUUG</a> melder i natt at
+NRK nå har bestemt seg for
+<a href="http://www.nuug.no/news/NRK_viser_filmen_om_Datalagringsdirektivet_f_rste_gang_2014_03_31.shtml">når
+den norske dokumentarfilmen om datalagringsdirektivet skal
+sendes</a> (se <a href="http://www.imdb.com/title/tt2832844/">IMDB</a>
+for detaljer om filmen) . Første visning blir på NRK2 mandag
+2014-03-31 kl. 19:50, og deretter visninger onsdag 2014-04-02
+kl. 12:30, fredag 2014-04-04 kl. 19:40 og søndag 2014-04-06 kl. 15:10.
+Jeg har sett dokumentaren, og jeg anbefaler enhver å se den selv. Som
+oppvarming mens vi venter anbefaler jeg Bjørn Stærks kronikk i
+Aftenposten fra i går,
+<a href="http://www.aftenposten.no/meninger/kronikker/Autoritar-gjokunge-7514915.html">Autoritær
+gjøkunge</a>, der han gir en grei skisse av hvor ille det står til med
+retten til privatliv og beskyttelsen av demokrati i Norge og resten
+verden, og helt riktig slår fast at det er vi i databransjen som
+sitter med nøkkelen til å gjøre noe med dette. Jeg har involvert meg
+i prosjektene <a href="http://www.dugnadsnett.no/">dugnadsnett.no</a>
+og <a href="https://wiki.debian.org/FreedomBox">FreedomBox</a> for å
+forsøke å gjøre litt selv for å bedre situasjonen, men det er mye
+hardt arbeid fra mange flere enn meg som gjenstår før vi kan sies å ha
+gjenopprettet balansen.</p>
+
+<p>Jeg regner med at nettutgaven dukker opp på
+<a href="http://tv.nrk.no/program/koid75005313/tema-dine-digitale-spor-datalagringsdirektivet">NRKs
+side om filmen om datalagringsdirektivet</a> om fem dager. Hold et
+øye med siden, og tips venner og slekt om at de også bør se den.</p>
