-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

+ <div class="date">10th September 2014</div>
+ <div class="body"><p>Yesterday, I had the pleasure of attending a talk with the
+<a href="http://www.nuug.no/">Norwegian Unix User Group</a> about
+<a href="http://www.nuug.no/aktiviteter/20140909-sks-keyservers/">the
+OpenPGP keyserver pool sks-keyservers.net</a>, and was very happy to
+learn that there is a large set of publicly available key servers to
+use when looking for peoples public key. So far I have used
+subkeys.pgp.net, and some times wwwkeys.nl.pgp.net when the former
+were misbehaving, but those days are ended. The servers I have used
+up until yesterday have been slow and some times unavailable. I hope
+those problems are gone now.</p>
+
+<p>Behind the round robin DNS entry of the
+<a href="https://sks-keyservers.net/">sks-keyservers.net</a> service
+there is a pool of more than 100 keyservers which are checked every
+day to ensure they are well connected and up to date. It must be
+better than what I have used so far. :)</p>
+
+<p>Yesterdays speaker told me that the service is the default
+keyserver provided by the default configuration in GnuPG, but this do
+not seem to be used in Debian. Perhaps it should?</p>
+
+<p>Anyway, I've updated my ~/.gnupg/options file to now include this
+line:</p>
+
+<p><blockquote><pre>
+keyserver pool.sks-keyservers.net
+</pre></blockquote></p>
+
+<p>With GnuPG version 2 one can also locate the keyserver using SRV
+entries in DNS. Just for fun, I did just that at work, so now every
+user of GnuPG at the University of Oslo should find a OpenGPG
+keyserver automatically should their need it:</p>
+
+<p><blockquote><pre>
+% host -t srv _pgpkey-http._tcp.uio.no
+_pgpkey-http._tcp.uio.no has SRV record 0 100 11371 pool.sks-keyservers.net.
+%
+</pre></blockquote></p>
+
+<p>Now if only
+<a href="http://ietfreport.isoc.org/idref/draft-shaw-openpgp-hkp/">the
+HKP lookup protocol</a> supported finding signature paths, I would be
+very happy. It can look up a given key or search for a user ID, but I
+normally do not want that, but to find a trust path from my key to
+another key. Given a user ID or key ID, I would like to find (and
+download) the keys representing a signature path from my key to the
+key in question, to be able to get a trust path between the two keys.
+This is as far as I can tell not possible today. Perhaps something
+for a future version of the protocol?</p>

- <div class="date">25th March 2014</div>
- <div class="body"><p>Did you ever need to store logs or other files in a way that would
-allow it to be used as evidence in court, and needed a way to
-demonstrate without reasonable doubt that the file had not been
-changed since it was created? Or, did you ever need to document that
-a given document was received at some point in time, like some
-archived document or the answer to an exam, and not changed after it
-was received? The problem in these settings is to remove the need to
-trust yourself and your computers, while still being able to prove
-that a file is the same as it was at some given time in the past.</p>
-
-<p>A solution to these problems is to have a trusted third party
-"stamp" the document and verify that at some given time the document
-looked a given way. Such
-<a href="https://en.wikipedia.org/wiki/Notarius">notarius</a> service
-have been around for thousands of years, and its digital equivalent is
-called a
-<a href="http://en.wikipedia.org/wiki/Trusted_timestamping">trusted
-timestamping service</a>. <a href="http://www.ietf.org/">The Internet
-Engineering Task Force</a> standardised how such service could work a
-few years ago as <a href="http://tools.ietf.org/html/rfc3161">RFC
-3161</a>. The mechanism is simple. Create a hash of the file in
-question, send it to a trusted third party which add a time stamp to
-the hash and sign the result with its private key, and send back the
-signed hash + timestamp. Both email, FTP and HTTP can be used to
-request such signature, depending on what is provided by the service
-used. Anyone with the document and the signature can then verify that
-the document matches the signature by creating their own hash and
-checking the signature using the trusted third party public key.
-There are several commercial services around providing such
-timestamping. A quick search for
-"<a href="https://duckduckgo.com/?q=rfc+3161+service">rfc 3161
-service</a>" pointed me to at least
-<a href="https://www.digistamp.com/technical/how-a-digital-time-stamp-works/">DigiStamp</a>,
-<a href="http://www.quovadisglobal.co.uk/CertificateServices/SigningServices/TimeStamp.aspx">Quo
-Vadis</a>,
-<a href="https://www.globalsign.com/timestamp-service/">Global Sign</a>
-and <a href="http://www.globaltrustfinder.com/TSADefault.aspx">Global
-Trust Finder</a>. The system work as long as the private key of the
-trusted third party is not compromised.</p>
-
-<p>But as far as I can tell, there are very few public trusted
-timestamp services available for everyone. I've been looking for one
-for a while now. But yesterday I found one over at
-<a href="https://www.pki.dfn.de/zeitstempeldienst/">Deutches
-Forschungsnetz</a> mentioned in
-<a href="http://www.d-mueller.de/blog/dealing-with-trusted-timestamps-in-php-rfc-3161/">a
-blog by David Müller</a>. I then found
-<a href="http://www.rz.uni-greifswald.de/support/dfn-pki-zertifikate/zeitstempeldienst.html">a
-good recipe on how to use the service</a> over at the University of
-Greifswald.</p>

-both server and tools to use and set up your own signing service. See

- <div class="body"><p>Keeping your DVD collection safe from scratches and curious
-children fingers while still having it available when you want to see a
-movie is not straight forward. My preferred method at the moment is
-to store a full copy of the ISO on a hard drive, and use VLC, Popcorn
-Hour or other useful players to view the resulting file. This way the
-subtitles and bonus material are still available and using the ISO is
-just like inserting the original DVD record in the DVD player.</p>
-
-<p>Earlier I used dd for taking security copies, but it do not handle
-DVDs giving read errors (which are quite a few of them). I've also
-tried using
-<a href="http://people.skolelinux.org/pere/blog/Ripping_problematic_DVDs_using_dvdbackup_and_genisoimage.html">dvdbackup
-and genisoimage</a>, but these days I use the marvellous python library
-and program
-<a href="http://bblank.thinkmo.de/blog/new-software-python-dvdvideo">python-dvdvideo</a>
-written by Bastian Blank. It is
-<a href="http://packages.qa.debian.org/p/python-dvdvideo.html">in Debian
-already</a> and the binary package name is python3-dvdvideo. Instead
-of trying to read every block from the DVD, it parses the file
-structure and figure out which block on the DVD is actually in used,
-and only read those blocks from the DVD. This work surprisingly well,
-and I have been able to almost backup my entire DVD collection using
-this method.</p>
-
-<p>So far, python-dvdvideo have failed on between 10 and
-20 DVDs, which is a small fraction of my collection. The most common
-problem is
-<a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=720831">DVDs
-using UTF-16 instead of UTF-8 characters</a>, which according to
-Bastian is against the DVD specification (and seem to cause some
-players to fail too). A rarer problem is what seem to be inconsistent
-DVD structures, as the python library
-<a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=723079">claim
-there is a overlap between objects</a>. An equally rare problem claim
-<a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=741878">some
-value is out of range</a>. No idea what is going on there. I wish I
-knew enough about the DVD format to fix these, to ensure my movie
-collection will stay with me in the future.</p>
-
-<p>So, if you need to keep your DVDs safe, back them up using
-python-dvdvideo. :)</p>

-kan en få tilgang til den på en enkel måte? Takket være et lite
-knippe lover og tilhørende forskrifter, blant annet
-<a href="http://lovdata.no/dokument/NL/lov/2006-05-19-16">offentlighetsloven</a>,

-har en rett til å spørre det offentlige og få svar. Men det finnes
-intet offentlig arkiv over hva andre har spurt om, og dermed risikerer en
-å måtte forstyrre myndighetene gang på gang for å få tak i samme
-informasjonen på nytt. <a href="http://www.mysociety.org/">Britiske
-mySociety</a> har laget tjenesten
-<a href="http://www.whatdotheyknow.com/">WhatDoTheyKnow</a> som gjør
-noe med dette. I Storbritannia blir WhatdoTheyKnow brukt i
-<a href="http://www.mysociety.org/2011/07/01/whatdotheyknows-share-of-central-government-foi-requests-q2-2011/">ca
-15% av alle innsynsforespørsler mot sentraladministrasjonen</a>.
-Prosjektet heter <a href="http://www.alaveteli.org/">Alaveteli</A>, og
-er takk i bruk en rekke steder etter at løsningen ble generalisert og
-gjort mulig å oversette. Den hjelper borgerne med å be om innsyn,
-rådgir ved purringer og klager og lar alle se hvilke henvendelser som
-er sendt til det offentlige og hvilke svar som er kommet inn, i et
-søkpart arkiv. Her i Norge holder vi i foreningen NUUG på å få opp en
-norsk utgave av Alaveteli, og her trenger vi din hjelp med
-oversettelsen.</p>
-
-<p>Så langt er 76 % av Alaveteli oversatt til norsk bokmål, men vi
-skulle gjerne vært oppe i 100 % før lansering. Oversettelsen gjøres
-på <a href="https://www.transifex.com/projects/p/alaveteli/">Transifex,
-der enhver som registrerer seg</a> og ber om tilgang til

-sette opp tjenesten) på maskinen
-<a href="http://alaveteli-dev.nuug.no/">alaveteli-dev.nuug.no</a>, der

-
-<p>Hvis noen vil oversette til nynorsk også, så skal vi finne ut

+ <div class="date">31st July 2014</div>
+ <div class="body"><p>The complete and free “out of the box” software solution for
+schools, <a href="http://www.skolelinux.org/">Debian Edu /
+Skolelinux</a>, is used quite a lot in Germany, and one of the people
+involved is Bernd Zeitzen, who show up on the project mailing lists
+from time to time with interesting questions and tips on how to adjust
+the setup. I managed to interview him this summer.</p>
+
+<p><strong>Who are you, and how do you spend your days?</strong></p>
+
+<p>My name is Bernd Zeitzen and I'm married with Hedda, a self
+employed physiotherapist. My former profession is tool maker, but I
+haven't worked for 30 years in this job. 30 years ago I started to
+support my wife and become her officeworker and a few years later the
+administrator for a small computer network, today based on Ubuntu
+Server (Samba, OpenVPN). For her daily work she has to use Windows
+Desktops because the software she needs to organize her business only
+works with Windows . :-(</p>
+
+<p>In 1988 we started with one PC and DOS, then I learned to use
+Windows 98, 2000, XP, …, 8, Ubuntu, MacOSX. Today we are running a
+Linux server with 6 Windows clients and 10 persons (teacher of
+children with special needs, speech therapist, occupational therapist,
+psychologist and officeworkers) using our Samba shares via OpenVPN to
+work with the documentations of our patients.</p>
+
+<p><strong>How did you get in contact with the Skolelinux / Debian Edu
+project?</strong></p>
+
+<p>Two years ago a friend of mine asked me, if I want to get a job in
+his school (<a href="http://www.gymnasium-harsewinkel.de/">Gymnasium
+Harsewinkel</a>). They started with Skolelinux / Debian Edu and they
+were looking for people to give support to the teachers using the
+software and the network and teaching the pupils increasing their
+computer skills in optional lessons. I'm spending 4-6 hours a week
+with this job.</p>
+
+<p><strong>What do you see as the advantages of Skolelinux / Debian
+Edu?</strong></p>
+
+<p>The independence.</p>
+
+<p>First: Every person is allowed to use, share and develop the
+software. Even if you are poor, you are allowed to use the software
+included in Skolelinux/Debian Edu and all the other Free Software.</p>
+
+<p>Second: The software runs on old machines and this gives us the
+possibility to recycle computers, weeded out from offices. The
+servers and desktops are running for more than two years and they are
+working reliable. </p>
+
+<p>We have two servers (one tjener and one terminal server), 45
+workstations in three classrooms and seven laptops as a mobile
+solution for all classrooms. These machines are all booting from the
+terminal server. In the moment we are installing 30 laptops as mobile
+workstations. Then the pupils have the possibility to work with these
+machines in their classrooms. Internet access is realized by a WLAN
+router, connected to the schools network. This is all done without a
+dedicated system administrator or a computer science teacher.</p>
+
+<p><strong>What do you see as the disadvantages of Skolelinux / Debian
+Edu?</strong></p>
+
+<p>Teachers and pupils are Windows users. <Irony on> And Linux
+isn't cool. It's software for freaks using the command line. <Irony
+off> They don't realize the stability of the system. </p>
+
+<p><strong>Which free software do you use daily?</strong></p>
+
+<p>Firefox, Thunderbird, LibreOffice, Ubuntu Server 12.04 (Samba,
+Apache, MySQL, Joomla!, … and Skolelinux / Debian Edu)</p>
+
+<p><strong>Which strategy do you believe is the right one to use to
+get schools to use free software?</strong></p>
+
+<p>In Germany we have the situation: every school is free to decide
+which software they want to use. This decision is influenced by
+teachers who learned to use Windows and MS Office. They buy a PC with
+Windows preinstalled and an additional testing version of MS
+Office. They don't know about the possibility to use Free Software
+instead. Another problem are the publisher of school books. They
+develop their software, added to the school books, for Windows.</p>

-project</a> is working on providing the software and hardware for
-making 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 has been
-going on for a while, and is slowly progressing towards a new test
-release (0.2).</p>
-
-<p>And what day could be better than the Pi day to announce that the
-new version will provide "hard drive" / SD card / USB stick images for
-Dreamplug, Raspberry Pi and VirtualBox (or any other virtualization
-system), and can also be installed using a Debian installer preseed
-file. The Debian based Freedombox is now based on Debian Jessie,
-where most of the needed packages used are already present. Only one,
-the freedombox-setup package, is missing. To try to build your own
-boot image to test the current status, fetch the freedom-maker scripts
-and build using
-<a href="http://packages.qa.debian.org/vmdebootstrap">vmdebootstrap</a>
-with a user with sudo access to become root:
-
-<pre>
-git clone http://anonscm.debian.org/git/freedombox/freedom-maker.git \
- freedom-maker
-sudo apt-get install git vmdebootstrap mercurial python-docutils \
- mktorrent extlinux virtualbox qemu-user-static binfmt-support \
- u-boot-tools
-make -C freedom-maker dreamplug-image raspberry-image virtualbox-image
-</pre>
-
-<p>Root access is needed to run debootstrap and mount loopback
-devices. See the README for more details on the build. If you do not
-want all three images, trim the make line. But note that thanks to <a
-href="https://bugs.debian.org/741407">a race condition in
-vmdebootstrap</a>, the build might fail without the patch to the
-kpartx call.</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>
-
-<pre>
-url=<a href="http://www.reinholdtsen.name/freedombox/preseed-jessie.dat">http://www.reinholdtsen.name/freedombox/preseed-jessie.dat</a>
-</pre>
-
-<p>But note that due to <a href="https://bugs.debian.org/740673">a
-recently introduced bug in apt in Jessie</a>, the installer will
-currently hang while setting up APT sources. Killing the
-'<tt>apt-cdrom ident</tt>' process when it hang a few times during the
-installation will get the installation going. This affect all
-installations in Jessie, and I expect it will be fixed soon.</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

- <div class="date">12th March 2014</div>
- <div class="body"><p>On larger sites, it is useful to use a dedicated storage server for
-storing user home directories and data. The design for handling this
-in <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a>, is
-to update the automount rules in LDAP and let the automount daemon on
-the clients take care of the rest. I was reminded about the need to
-document this better when one of the customers of
-<a href="http://www.slxdrift.no/">Skolelinux Drift AS</a>, where I am
-on the board of directors, asked about how to do this. The steps to
-get this working are the following:</p>
-
-<p><ol>
-
-<li>Add new storage server in DNS. I use nas-server.intern as the
-example host here.</li>
-
-<li>Add automoun LDAP information about this server in LDAP, to allow
-all clients to automatically mount it on reqeust.</li>
-
-<li>Add the relevant entries in tjener.intern:/etc/fstab, because
-tjener.intern do not use automount to avoid mounting loops.</li>
-
-</ol></p>
-
-<p>DNS entries are added in GOsa², and not described here. Follow the
-<a href="https://wiki.debian.org/DebianEdu/Documentation/Wheezy/GettingStarted">instructions
-in the manual</a> (Machine Management with GOsa² in section Getting
-started).</p>
-
-<p>Ensure that the NFS export points on the server are exported to the
-relevant subnets or machines:</p>
-
-<p><blockquote><pre>
-root@tjener:~# showmount -e nas-server
-Export list for nas-server:
-/storage 10.0.0.0/8
-root@tjener:~#
-</pre></blockquote></p>
-
-<p>Here everything on the backbone network is granted access to the
-/storage export. With NFSv3 it is slightly better to limit it to
-netgroup membership or single IP addresses to have some limits on the
-NFS access.</p>
-
-<p>The next step is to update LDAP. This can not be done using GOsa²,
-because it lack a module for automount. Instead, use ldapvi and add
-the required LDAP objects using an editor.</p>
-
-<p><blockquote><pre>
-ldapvi --ldap-conf -ZD '(cn=admin)' -b ou=automount,dc=skole,dc=skolelinux,dc=no
-</pre></blockquote></p>
-
-<p>When the editor show up, add the following LDAP objects at the
-bottom of the document. The "/&" part in the last LDAP object is a
-wild card matching everything the nas-server exports, removing the
-need to list individual mount points in LDAP.</p>
-
-<p><blockquote><pre>
-add cn=nas-server,ou=auto.skole,ou=automount,dc=skole,dc=skolelinux,dc=no
-objectClass: automount
-cn: nas-server
-automountInformation: -fstype=autofs --timeout=60 ldap:ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
-
-add ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
-objectClass: top
-objectClass: automountMap
-ou: auto.nas-server
-
-add cn=/,ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
-objectClass: automount
-cn: /
-automountInformation: -fstype=nfs,tcp,rsize=32768,wsize=32768,rw,intr,hard,nodev,nosuid,noatime nas-server.intern:/&
-</pre></blockquote></p>
-
-<p>The last step to remember is to mount the relevant mount points in
-tjener.intern by adding them to /etc/fstab, creating the mount
-directories using mkdir and running "mount -a" to mount them.</p>
-
-<p>When this is done, your users should be able to access the files on
-the storage server directly by just visiting the
-/tjener/nas-server/storage/ directory using any application on any
-workstation, LTSP client or LTSP server.</p>

+But we also want to make sure each language contain the same
+information, so for this we need a good way to keep the translations
+in sync. And we want it to be easy for our users to improve the
+documentation, avoiding the need to learn special formats or tools to
+contribute, and the obvious way to do this is to make it possible to
+edit the documentation using a web browser. We also want it to be
+easy for translators to keep the translation up to date, and give them
+help in figuring out what need to be translated. Here is the list of
+tools and the process we have found trying to reach all these
+goals.</p>
+
+<p>We maintain the authoritative source of our manual in the
+<a href="https://wiki.debian.org/DebianEdu/Documentation/Wheezy/">Debian
+wiki</a>, as several wiki pages written in English. It consist of one
+front page with references to the different chapters, several pages
+for each chapter, and finally one "collection page" gluing all the
+chapters together into one large web page (aka
+<a href="https://wiki.debian.org/DebianEdu/Documentation/Wheezy/AllInOne">the
+AllInOne page</a>). The AllInOne page is the one used for further
+processing and translations. Thanks to the fact that the
+<a href="http://moinmo.in/">MoinMoin</a> installation on
+wiki.debian.org support exporting pages in
+<a href="http://www.docbook.org/">the Docbook format</a>, we can fetch
+the list of pages to export using the raw version of the AllInOne
+page, loop over each of them to generate a Docbook XML version of the
+manual. This process also download images and transform image
+references to use the locally downloaded images. The generated
+Docbook XML files are slightly broken, so some post-processing is done
+using the <tt>documentation/scripts/get_manual</tt> program, and the
+result is a nice Docbook XML file (debian-edu-wheezy-manual.xml) and
+a handfull of images. The XML file can now be used to generate PDF, HTML
+and epub versions of the English manual. This is the basic step of
+our process, making PDF (using dblatex), HTML (using xsltproc) and
+epub (using dbtoepub) version from Docbook XML, and the resulting files
+are placed in the debian-edu-doc-en binary package.</p>
+
+<p>But English documentation is not enough for us. We want translated
+documentation too, and we want to make it easy for translators to
+track the English original. For this we use the
+<a href="http://packages.qa.debian.org/p/poxml.html">poxml</a> package,
+which allow us to transform the English Docbook XML file into a
+translation file (a .pot file), usable with the normal gettext based
+translation tools used by those translating free software. The pot
+file is used to create and maintain translation files (several .po
+files), which the translations update with the native language
+translations of all titles, paragraphs and blocks of text in the
+original. The next step is combining the original English Docbook XML
+and the translation file (say debian-edu-wheezy-manual.nb.po), to
+create a translated Docbook XML file (in this case
+debian-edu-wheezy-manual.nb.xml). This translated (or partly
+translated, if the translation is not complete) Docbook XML file can
+then be used like the original to create a PDF, HTML and epub version
+of the documentation.</p>
+
+<p>The translators use different tools to edit the .po files. We
+recommend using
+<a href="http://www.kde.org/applications/development/lokalize/">lokalize</a>,
+while some use emacs and vi, others can use web based editors like
+<a href="http://pootle.translatehouse.org/">Poodle</a> or
+<a href="https://www.transifex.com/">Transifex</a>. All we care about
+is where the .po file end up, in our git repository. Updated
+translations can either be committed directly to git, or submitted as
+<a href="https://bugs.debian.org/src:debian-edu-doc">bug reports
+against the debian-edu-doc package</a>.</p>
+
+<p>One challenge is images, which both might need to be translated (if
+they show translated user applications), and are needed in different
+formats when creating PDF and HTML versions (epub is a HTML version in
+this regard). For this we transform the original PNG images to the
+needed density and format during build, and have a way to provide
+translated images by storing translated versions in
+images/$LANGUAGECODE/. I am a bit unsure about the details here. The
+package maintainers know more.</p>
+
+<p>If you wonder what the result look like, we provide
+<a href="http://maintainer.skolelinux.org/debian-edu-doc/">the content
+of the documentation packages on the web</a>. See for example the
+<a href="http://maintainer.skolelinux.org/debian-edu-doc/it/debian-edu-wheezy-manual.pdf">Italian
+PDF version</a> or the
+<a href="http://maintainer.skolelinux.org/debian-edu-doc/de/debian-edu-wheezy-manual.html">German
+HTML version</a>. We do not yet build the epub version by default,
+but perhaps it will be done in the future.</p>

- <div class="date"> 7th March 2014</div>
- <div class="body"><p>For noen uker siden ble NXCs fri programvarelisenserte
-NOARK5-løsning
-<a href="http://www.nuug.no/aktiviteter/20140211-noark/">presentert hos
-NUUG</a> (video
-<a href="https://www.youtube.com/watch?v=JCb_dNS3MHQ">på youtube
-foreløbig</a>), og det fikk meg til å titte litt mer på NOARK5,
-standarden for arkivhåndtering i det offentlige Norge. Jeg lurer på
-om denne kjernen kan være nyttig i et par av mine prosjekter, og for ett
-av dem er det mest aktuelt å lagre epost. Jeg klarte ikke finne noen
-anbefaling om hvordan RFC 822-formattert epost (aka Internett-epost)
-burde lagres i NOARK5, selv om jeg vet at noen arkiver tar
-PDF-utskrift av eposten med sitt epostprogram og så arkiverer PDF-en
-(eller enda værre, tar papirutskrift og lagrer bildet av eposten som
-PDF i arkivet).</p>
-
-<p>Det er ikke så mange formater som er akseptert av riksarkivet til
-langtidsoppbevaring av offentlige arkiver, og PDF og XML er de mest
-aktuelle i så måte. Det slo meg at det måtte da finnes en eller annen
-egnet XML-representasjon og at det kanskje var enighet om hvilken som
-burde brukes, så jeg tok mot til meg og spurte
-<a href="http://samdok.com/">SAMDOK</a>, en gruppe tilknyttet
-arkivverket som ser ut til å jobbe med NOARK-samhandling, om de hadde
-noen anbefalinger:
-
-<p><blockquote>
-<p>Hei.</p>
-
-<p>Usikker på om dette er riktig forum å ta opp mitt spørsmål, men jeg
-lurer på om det er definert en anbefaling om hvordan RFC
-822-formatterte epost (aka vanlig Internet-epost) bør lages håndteres
-i NOARK5, slik at en bevarer all informasjon i eposten
-(f.eks. Received-linjer). Finnes det en anbefalt XML-mapping ala den
-som beskrives på
-<URL: <a href="https://www.informit.com/articles/article.aspx?p=32074">https://www.informit.com/articles/article.aspx?p=32074</a> >? Mitt
-mål er at det skal være mulig å lagre eposten i en NOARK5-kjerne og
-kunne få ut en identisk formattert kopi av opprinnelig epost ved
-behov.</p>
-</blockquote></p>
-
-<p>Postmottaker hos SAMDOK mente spørsmålet heller burde stilles
-direkte til riksarkivet, og jeg fikk i dag svar derfra formulert av
-seniorrådgiver Geir Ivar Tungesvik:</p>
-
-<p><blockquote>
-<p>Riksarkivet har ingen anbefalinger når det gjelder konvertering fra
-e-post til XML. Det står arkivskaper fritt å eventuelt definere/bruke
-eget format. Inklusive da - som det spørres om - et format der det er
-mulig å re-etablere e-post format ut fra XML-en. XML (e-post)
-dokumenter må være referert i arkivstrukturen, og det må vedlegges et
-gyldig XML skjema (.xsd) for XML-filene. Arkivskaper står altså fritt
-til å gjøre hva de vil, bare det dokumenteres og det kan dannes et
-utrekk ved avlevering til depot.</p>
-
-<p>De obligatoriske kravene i Noark 5 standarden må altså oppfylles -
-etter dialog med Riksarkivet i forbindelse med godkjenning. For
-offentlige arkiv er det særlig viktig med filene loependeJournal.xml
-og offentligJournal.xml. Private arkiv som vil forholde seg til Noark
-5 standarden er selvsagt frie til å bruke det som er relevant for dem
-av obligatoriske krav.</p>
-</blockquote></p>
-
-<p>Det ser dermed ut for meg som om det er et lite behov for å
-standardisere XML-lagring av RFC-822-formatterte meldinger. Noen som
-vet om god spesifikasjon i så måte? I tillegg til den omtalt over,
-har jeg kommet over flere aktuelle beskrivelser (søk på "rfc 822
-xml", så finner du aktuelle alternativer).</p>
-
-<ul>
-
-<li><a href="http://www.openhealth.org/xmtp/">XML MIME Transformation
-protocol (XMTP)</a> fra OpenHealth, sist oppdatert 2001.</li>

- <div class="body"><p>Many years ago, I wrote a GPL licensed version of the netgroup and
-innetgr tools, because I needed them in
-<a href="http://www.skolelinux.org/">Skolelinux</a>. I called the project
-ng-utils, and it has served me well. I placed the project under the
-<a href="http://www.hungry.com/">Hungry Programmer</a> umbrella, and it was maintained in our CVS
-repository. But many years ago, the CVS repository was dropped (lost,
-not migrated to new hardware, not sure), and the project have lacked a
-proper home since then.</p>
-
-<p>Last summer, I had a look at the package and made a new release
-fixing a irritating crash bug, but was unable to store the changes in
-a proper source control system. I applied for a project on
-<a href="https://alioth.debian.org/">Alioth</a>, but did not have time
-to follow up on it. Until today. :)</p>
-
-<p>After many hours of cleaning and migration, the ng-utils project
-now have a new home, and a git repository with the highlight of the
-history of the project. I published all release tarballs and imported
-them into the git repository. As the project is really stable and not
-expected to gain new features any time soon, I decided to make a new

+ <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="irc://irc.freenode.net/#gnash">the #gnash channel on

- <div class="date"> 3rd February 2014</div>
- <div class="body"><p>A few days ago I decided to try to help the Hurd people to get
-their changes into sysvinit, to allow them to use the normal sysvinit
-boot system instead of their old one. This follow up on the
-<a href="https://teythoon.cryptobitch.de//categories/gsoc.html">great
-Google Summer of Code work</a> done last summer by Justus Winter to
-get Debian on Hurd working more like Debian on Linux. To get started,
-I downloaded a prebuilt hard disk image from
-<a href="http://ftp.debian-ports.org/debian-cd/hurd-i386/current/debian-hurd.img.tar.gz">http://ftp.debian-ports.org/debian-cd/hurd-i386/current/debian-hurd.img.tar.gz</a>,
-and started it using virt-manager.</p>
-
-<p>The first think I had to do after logging in (root without any
-password) was to get the network operational. I followed
-<a href="https://www.debian.org/ports/hurd/hurd-install">the
-instructions on the Debian GNU/Hurd ports page</a> and ran these
-commands as root to get the machine to accept a IP address from the
-kvm internal DHCP server:</p>
-
-<p><blockquote><pre>
-settrans -fgap /dev/netdde /hurd/netdde
-kill $(ps -ef|awk '/[p]finet/ { print $2}')
-kill $(ps -ef|awk '/[d]evnode/ { print $2}')
-dhclient /dev/eth0
-</pre></blockquote></p>
-
-<p>After this, the machine had internet connectivity, and I could
-upgrade it and install the sysvinit packages from experimental and
-enable it as the default boot system in Hurd.</p>
-
-<p>But before I did that, I set a password on the root user, as ssh is
-running on the machine it for ssh login to work a password need to be
-set. Also, note that a bug somewhere in openssh on Hurd block
-compression from working. Remember to turn that off on the client
-side.</p>
-
-<p>Run these commands as root to upgrade and test the new sysvinit
-stuff:</p>
-
-<p><blockquote><pre>
-cat > /etc/apt/sources.list.d/experimental.list <<EOF
-deb http://http.debian.net/debian/ experimental main
-EOF
-apt-get update
-apt-get dist-upgrade
-apt-get install -t experimental initscripts sysv-rc sysvinit \
- sysvinit-core sysvinit-utils
-update-alternatives --config runsystem
-</pre></blockquote></p>
-
-<p>To reboot after switching boot system, you have to use
-<tt>reboot-hurd</tt> instead of just <tt>reboot</tt>, as there is not
-yet a sysvinit process able to receive the signals from the normal
-'reboot' command. After switching to sysvinit as the boot system,
-upgrading every package and rebooting, the network come up with DHCP
-after boot as it should, and the settrans/pkill hack mentioned at the
-start is no longer needed. But for some strange reason, there are no
-longer any login prompt in the virtual console, so I logged in using
-ssh instead.
-
-<p>Note that there are some race conditions in Hurd making the boot
-fail some times. No idea what the cause is, but hope the Hurd porters
-figure it out. At least Justus said on IRC (#debian-hurd on
-irc.debian.org) that they are aware of the problem. A way to reduce
-the impact is to upgrade to the Hurd packages built by Justus by
-adding this repository to the machine:</p>

+ <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>
-cat > /etc/apt/sources.list.d/hurd-ci.list <<EOF
-deb http://darnassus.sceen.net/~teythoon/hurd-ci/ sid main
-EOF
+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>At the moment the prebuilt virtual machine get some packages from
-http://ftp.debian-ports.org/debian, because some of the packages in
-unstable do not yet include the required patches that are lingering in
-BTS. This is the completely list of "unofficial" packages installed:</p>
+<p>The second part is in
+<tt>/usr/lib/tasksel/packages/for-current-hardware</tt> and look like
+this:</p>
<p><blockquote><pre>
-# aptitude search '?narrow(?version(CURRENT),?origin(Debian Ports))'
-i emacs - GNU Emacs editor (metapackage)

-<p>All in all, testing hurd has been an interesting experience. :)
-X.org did not work out of the box and I never took the time to follow
-the porters instructions to fix it. This time I was interested in the
-command line stuff.<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>
