- <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> 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>

+ <div class="date">25th September 2014</div>
+ <div class="body"><p>I use the <a href="https://sourceforge.net/p/lsdvd/">lsdvd tool</a>
+to handle my fairly large DVD collection. It is a nice command line
+tool to get details about a DVD, like title, tracks, track length,
+etc, in XML, Perl or human readable format. But lsdvd have not seen
+any new development since 2006 and had a few irritating bugs affecting
+its use with some DVDs. Upstream seemed to be dead, and in January I
+sent a small probe asking for a version control repository for the
+project, without any reply. But I use it regularly and would like to
+get <a href="https://packages.qa.debian.org/lsdvd">an updated version
+into Debian</a>. So two weeks ago I tried harder to get in touch with
+the project admin, and after getting a reply from him explaining that
+he was no longer interested in the project, I asked if I could take
+over. And yesterday, I became project admin.</p>
+
+<p>I've been in touch with a Gentoo developer and the Debian
+maintainer interested in joining forces to maintain the upstream
+project, and I hope we can get a new release out fairly quickly,
+collecting the patches spread around on the internet into on place.
+I've added the relevant Debian patches to the freshly created git
+repository, and expect the Gentoo patches to make it too. If you got
+a DVD collection and care about command line tools, check out
+<a href="https://sourceforge.net/p/lsdvd/git/ci/master/tree/">the git source</a> and join
+<a href="https://sourceforge.net/p/lsdvd/mailman/">the project mailing
+list</a>. :)</p>

- <div class="body"><p>Det offentlige Norge har mye kunnskap og informasjon. Men hvordan
-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>,
-<a href="http://lovdata.no/dokument/NL/lov/2003-05-09-31">miljøinformasjonsloven</a>
-og
-<a href="http://lovdata.no/dokument/NL/lov/1967-02-10/">forvaltningsloven</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
-bokmålsoversettelsen får bidra. Vi har satt opp en test av tjenesten
-(som ikke sender epost til det offentlige, kun til oss som holder på å
-sette opp tjenesten) på maskinen
-<a href="http://alaveteli-dev.nuug.no/">alaveteli-dev.nuug.no</a>, der
-en kan se hvordan de oversatte meldingen blir seende ut på nettsiden.
-Når tjenesten lanseres vil den hete

-visdomskilden som Odin måtte gi øyet sitt for å få drikke i. Den
-nettsiden er er ennå ikke klar til bruk.</p>
-
-<p>Hvis noen vil oversette til nynorsk også, så skal vi finne ut
-hvordan vi lager en flerspråklig tjeneste. Men i første omgang er
-fokus på bokmålsoversettelsen, der vi selv har nok peiling til å ha
-fått oversatt 76%, men trenger hjelp for å komme helt i mål. :)</p>

+ <div class="date">21st September 2014</div>
+ <div class="body"><p>Rundt omkring i Oslo og Østlandsområdet henger det bokser over
+veiene som jeg har lurt på hva gjør. De har ut fra plassering og
+vinkling sett ut som bokser som sniffer ut et eller annet fra
+forbipasserende trafikk, men det har vært uklart for meg hva det er de
+leser av. Her om dagen tok jeg bilde av en slik boks som henger under
+<a href="http://www.openstreetmap.no/?zoom=19&mlat=59.96396&mlon=10.34443&layers=B00000">ei
+skibru på Sollihøgda</a>:</p>

+
+<p>Boksen er tydelig merket «Kapsch >>>», logoen til
+<a href="http://www.kapsch.net/">det sveitsiske selskapet Kapsch</a> som
+blant annet lager sensorsystemer for veitrafikk. Men de lager mye
+forskjellig, og jeg kjente ikke igjen boksen på utseendet etter en
+kjapp titt på produktlista til selskapet.</p>
+
+<p>I og med at boksen henger over veien E16, en riksvei vedlikeholdt
+av Statens Vegvesen, så antok jeg at det burde være mulig å bruke
+REST-API-et som gir tilgang til vegvesenets database over veier,
+skilter og annet veirelatert til å finne ut hva i alle dager dette
+kunne være. De har både
+<a href="https://www.vegvesen.no/nvdb/api/dokumentasjon/datakatalog">en
+datakatalog</a> og
+<a href="https://www.vegvesen.no/nvdb/api/dokumentasjon/sok">et
+søk</a>, der en kan søke etter ulike typer oppføringer innen for et
+gitt geografisk område. Jeg laget et enkelt shell-script for å hente
+ut antall av en gitt type innenfor området skibrua dekker, og listet
+opp navnet på typene som ble funnet. Orket ikke slå opp hvordan
+URL-koding av aktuelle strenger kunne gjøres mer generisk, og brukte
+en stygg sed-linje i stedet.</p>
+
+<blockquote><pre>

+
+<p>Av disse ser ID 775 og 862 mest relevant ut. ID 775 antar jeg
+refererer til fotoboksen som står like ved brua, mens
+«Reisetidsregistreringspunkt» kanskje kan være boksen som henger der.
+Hvordan finner jeg så ut hva dette kan være for noe. En titt på
+<a href="http://labs.vegdata.no/nvdb-datakatalog/862-Reisetidsregistreringspunkt/">datakatalogsiden
+for ID 862/Reisetidsregistreringspunkt</a> viser at det er finnes 53
+slike målere i Norge, og hvor de er plassert, men gir ellers få
+detaljer. Det er plassert 40 på østlandet og 13 i Trondheimsregionen.
+Men siden nevner «AutoPASS», og hvis en slår opp oppføringen på
+Sollihøgda nevner den «Ciber AS» som ID for eksternt system. (Kan det
+være snakk om
+<a href="http://www.proff.no/selskap/ciber-norge-as/oslo/internettdesign-og-programmering/Z0I3KMF4/">Ciber
+Norge AS</a>, et selskap eid av Ciber Europe Bv?) Et nettsøk på
+ «Ciber AS autopass» fører meg til en artikkel fra NRK Trøndelag i
+ 2013 med tittel
+«<a href="http://www.nrk.no/trondelag/sjekk-dette-hvis-du-vil-unnga-ko-1.11327947">Sjekk
+dette hvis du vil unngå kø</a>». Artikkelen henviser til vegvesenets
+nettside
+<a href="http://www.reisetider.no/reisetid/forside.html">reisetider.no</a>
+som har en
+<a href="http://www.reisetider.no/reisetid/omrade.html?omrade=5">kartside
+for Østlandet</a> som viser at det måles mellom Sandvika og Sollihøgda.
+Det kan dermed se ut til at jeg har funnet ut hva boksene gjør.</p>
+
+<p>Hvis det stemmer, så er dette bokser som leser av AutoPASS-ID-en
+til alle passerende biler med AutoPASS-brikke, og dermed gjør det mulig
+for de som kontrollerer boksene å holde rede på hvor en gitt bil er
+når den passerte et slikt målepunkt. NRK-artikkelen forteller at
+denne informasjonen i dag kun brukes til å koble to
+AutoPASS-brikkepasseringer passeringer sammen for å beregne
+reisetiden, og at bruken er godkjent av Datatilsynet. Det er desverre
+ikke mulig for en sjåfør som passerer under en slik boks å kontrollere
+at AutoPASS-ID-en kun brukes til dette i dag og i fremtiden.</p>
+
+<p>I tillegg til denne type AutoPASS-sniffere vet jeg at det også
+finnes mange automatiske stasjoner som tar betalt pr. passering (aka
+bomstasjoner), og der lagres informasjon om tid, sted og bilnummer i
+10 år. Finnes det andre slike sniffere plassert ut på veiene?</p>
+
+<p>Personlig har jeg valgt å ikke bruke AutoPASS-brikke, for å gjøre
+det vanskeligere og mer kostbart for de som vil invadere privatsfæren
+og holde rede på hvor bilen min beveger seg til enhver tid. Jeg håper
+flere vil gjøre det samme, selv om det gir litt høyere private
+utgifter (dyrere bompassering). Vern om privatsfæren koster i disse
+dager.</p>
+
+<p>Takk til Jan Kristian Jensen i Statens Vegvesen for tips om
+dokumentasjon på vegvesenets REST-API.</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>
-
-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">16th September 2014</div>
+ <div class="body"><p>The <a href="https://www.debian.org/">Debian</a> installer could be
+a lot quicker. When we install more than 2000 packages in
+<a href="http://www.skolelinux.org/">Skolelinux / Debian Edu</a> using
+tasksel in the installer, unpacking the binary packages take forever.
+A part of the slow I/O issue was discussed in
+<a href="https://bugs.debian.org/613428">bug #613428</a> about too
+much file system sync-ing done by dpkg, which is the package
+responsible for unpacking the binary packages. Other parts (like code
+executed by postinst scripts) might also sync to disk during
+installation. All this sync-ing to disk do not really make sense to
+me. If the machine crash half-way through, I start over, I do not try
+to salvage the half installed system. So the failure sync-ing is
+supposed to protect against, hardware or system crash, is not really
+relevant while the installer is running.</p>
+
+<p>A few days ago, I thought of a way to get rid of all the file
+system sync()-ing in a fairly non-intrusive way, without the need to
+change the code in several packages. The idea is not new, but I have
+not heard anyone propose the approach using dpkg-divert before. It
+depend on the small and clever package
+<a href="https://packages.qa.debian.org/eatmydata">eatmydata</a>, which
+uses LD_PRELOAD to replace the system functions for syncing data to
+disk with functions doing nothing, thus allowing programs to live
+dangerous while speeding up disk I/O significantly. Instead of
+modifying the implementation of dpkg, apt and tasksel (which are the
+packages responsible for selecting, fetching and installing packages),
+it occurred to me that we could just divert the programs away, replace
+them with a simple shell wrapper calling
+"eatmydata $program $@", to get the same effect.
+Two days ago I decided to test the idea, and wrapped up a simple
+implementation for the Debian Edu udeb.</p>
+
+<p>The effect was stunning. In my first test it reduced the running
+time of the pkgsel step (installing tasks) from 64 to less than 44
+minutes (20 minutes shaved off the installation) on an old Dell
+Latitude D505 machine. I am not quite sure what the optimised time
+would have been, as I messed up the testing a bit, causing the debconf
+priority to get low enough for two questions to pop up during
+installation. As soon as I saw the questions I moved the installation
+along, but do not know how long the question were holding up the

+yourself. In Debian Edu, the tasksel dialog do not show up, and the

+
+<p>The test is done using a netinst ISO on a USB stick, so some of the
+time is spent downloading packages. The connection to the Internet
+was 100Mbit/s during testing, so downloading should not be a
+significant factor in the measurement. Download typically took a few
+seconds to a few minutes, depending on the amount of packages being
+installed.</p>
+
+<p>The speedup is implemented by using two hooks in
+<a href="https://www.debian.org/devel/debian-installer/">Debian
+Installer</a>, the pre-pkgsel.d hook to set up the diverts, and the
+finish-install.d hook to remove the divert at the end of the
+installation. I picked the pre-pkgsel.d hook instead of the
+post-base-installer.d hook because I test using an ISO without the
+eatmydata package included, and the post-base-installer.d hook in
+Debian Edu can only operate on packages included in the ISO. The
+negative effect of this is that I am unable to activate this
+optimization for the kernel installation step in d-i. If the code is
+moved to the post-base-installer.d hook, the speedup would be larger
+for the entire installation.</p>
+
+<p>I've implemented this in the
+<a href="https://packages.qa.debian.org/debian-edu-install">debian-edu-install</a>
+git repository, and plan to provide the optimization as part of the
+Debian Edu installation. If you want to test this yourself, you can
+create two files in the installer (or in an udeb). One shell script
+need do go into /usr/lib/pre-pkgsel.d/, with content like this:</p>
+
+<p><blockquote><pre>
+#!/bin/sh
+set -e
+. /usr/share/debconf/confmodule
+info() {
+ logger -t my-pkgsel "info: $*"
+}
+error() {
+ logger -t my-pkgsel "error: $*"
+}
+override_install() {
+ apt-install eatmydata || true
+ if [ -x /target/usr/bin/eatmydata ] ; then
+ for bin in dpkg apt-get aptitude tasksel ; do
+ file=/usr/bin/$bin
+ # Test that the file exist and have not been diverted already.
+ if [ -f /target$file ] ; then
+ info "diverting $file using eatmydata"
+ printf "#!/bin/sh\neatmydata $bin.distrib \"\$@\"\n" \
+ > /target$file.edu
+ chmod 755 /target$file.edu
+ in-target dpkg-divert --package debian-edu-config \
+ --rename --quiet --add $file
+ ln -sf ./$bin.edu /target$file
+ else
+ error "unable to divert $file, as it is missing."
+ fi
+ done
+ else
+ error "unable to find /usr/bin/eatmydata after installing the eatmydata pacage"
+ fi
+}
+
+override_install
+</pre></blockquote></p>
+
+<p>To clean up, another shell script should go into
+/usr/lib/finish-install.d/ with code like this:
+
+<p><blockquote><pre>
+#! /bin/sh -e
+. /usr/share/debconf/confmodule
+error() {
+ logger -t my-finish-install "error: $@"
+}
+remove_install_override() {
+ for bin in dpkg apt-get aptitude tasksel ; do
+ file=/usr/bin/$bin
+ if [ -x /target$file.edu ] ; then
+ rm /target$file
+ in-target dpkg-divert --package debian-edu-config \
+ --rename --quiet --remove $file
+ rm /target$file.edu
+ else
+ error "Missing divert for $file."
+ fi
+ done
+ sync # Flush file buffers before continuing
+}
+
+remove_install_override
+</pre></blockquote></p>
+
+<p>In Debian Edu, I placed both code fragments in a separate script
+edu-eatmydata-install and call it from the pre-pkgsel.d and
+finish-install.d scripts.</p>
+
+<p>By now you might ask if this change should get into the normal
+Debian installer too? I suspect it should, but am not sure the
+current debian-installer coordinators find it useful enough. It also
+depend on the side effects of the change. I'm not aware of any, but I
+guess we will see if the change is safe after some more testing.
+Perhaps there is some package in Debian depending on sync() and
+fsync() having effect? Perhaps it should go into its own udeb, to
+allow those of us wanting to enable it to do so without affecting
+everyone.</p>
+
+<p>Update 2014-09-24: Since a few days ago, enabling this optimization
+will break installation of all programs using gnutls because of
+<a href="https://bugs.debian.org/702711">bug #702711. An updated
+eatmydata package in Debian will solve it.</p>

- <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>
+ <div class="title"><a href="http://people.skolelinux.org/pere/blog/Good_bye_subkeys_pgp_net__welcome_pool_sks_keyservers_net.html">Good bye subkeys.pgp.net, welcome pool.sks-keyservers.net</a></div>
+ <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>
-ldapvi --ldap-conf -ZD '(cn=admin)' -b ou=automount,dc=skole,dc=skolelinux,dc=no
+keyserver pool.sks-keyservers.net
</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>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>
-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:/&
+% 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>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>
+<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>

-<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>Note the requirement that the videos created can only be used for

-<p>Det ser dermed ut for meg som om det er et lite behov for å

- <div class="date">22nd February 2014</div>
- <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
-release and call it 1.0. Visit the new project home on
-<a href="https://alioth.debian.org/projects/ng-utils/">https://alioth.debian.org/projects/ng-utils/</a>

+ <div class="title"><a href="http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Bernd_Zeitzen.html">Debian Edu interview: Bernd Zeitzen</a></div>
+ <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>

- <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>
-
-<p><blockquote><pre>
-cat > /etc/apt/sources.list.d/hurd-ci.list <<EOF
-deb http://darnassus.sceen.net/~teythoon/hurd-ci/ sid main
-EOF
-</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><blockquote><pre>
-# aptitude search '?narrow(?version(CURRENT),?origin(Debian Ports))'
-i emacs - GNU Emacs editor (metapackage)
-i gdb - GNU Debugger
-i hurd-recommended - Miscellaneous translators
-i isc-dhcp-client - ISC DHCP client
-i isc-dhcp-common - common files used by all the isc-dhcp* packages
-i libc-bin - Embedded GNU C Library: Binaries

-i xorg - X.Org X Window System
-i A xserver-xorg - X.Org X server
-i A xserver-xorg-input-all - X.Org X server -- input driver metapackage
-#
-</pre></blockquote></p>
-
-<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>

- <div class="date">29th January 2014</div>
- <div class="body"><p>Bitcoin is a incredible use of peer to peer communication and
-encryption, allowing direct and immediate money transfer without any
-central control. It is sometimes claimed to be ideal for illegal
-activity, which I believe is quite a long way from the truth. At least
-I would not conduct illegal money transfers using a system where the
-details of every transaction are kept forever. This point is
-investigated in
-<a href="https://www.usenix.org/publications/login">USENIX ;login:</a>
-from December 2013, in the article
-"<a href="https://www.usenix.org/system/files/login/articles/03_meiklejohn-online.pdf">A
-Fistful of Bitcoins - Characterizing Payments Among Men with No
-Names</a>" by Sarah Meiklejohn, Marjori Pomarole,Grant Jordan, Kirill
-Levchenko, Damon McCoy, Geoffrey M. Voelker, and Stefan Savage. They
-analyse the transaction log in the Bitcoin system, using it to find
-addresses belong to individuals and organisations and follow the flow
-of money from both Bitcoin theft and trades on Silk Road to where the
-money end up. This is how they wrap up their article:</p>
-
-<p><blockquote>
-<p>"To demonstrate the usefulness of this type of analysis, we turned
-our attention to criminal activity. In the Bitcoin economy, criminal
-activity can appear in a number of forms, such as dealing drugs on
-Silk Road or simply stealing someone else’s bitcoins. We followed the
-flow of bitcoins out of Silk Road (in particular, from one notorious
-address) and from a number of highly publicized thefts to see whether
-we could track the bitcoins to known services. Although some of the
-thieves attempted to use sophisticated mixing techniques (or possibly
-mix services) to obscure the flow of bitcoins, for the most part
-tracking the bitcoins was quite straightforward, and we ultimately saw
-large quantities of bitcoins flow to a variety of exchanges directly
-from the point of theft (or the withdrawal from Silk Road).</p>
-
-<p>As acknowledged above, following stolen bitcoins to the point at
-which they are deposited into an exchange does not in itself identify
-the thief; however, it does enable further de-anonymization in the
-case in which certain agencies can determine (through, for example,
-subpoena power) the real-world owner of the account into which the
-stolen bitcoins were deposited. Because such exchanges seem to serve
-as chokepoints into and out of the Bitcoin economy (i.e., there are
-few alternative ways to cash out), we conclude that using Bitcoin for
-money laundering or other illicit purposes does not (at least at
-present) seem to be particularly attractive."</p>
-</blockquote><p>
-
-<p>These researches are not the first to analyse the Bitcoin
-transaction log. The 2011 paper
-"<a href="http://arxiv.org/abs/1107.4524">An Analysis of Anonymity in
-the Bitcoin System</A>" by Fergal Reid and Martin Harrigan is
-summarized like this:</p>
-
-<p><blockquote>
-"Anonymity in Bitcoin, a peer-to-peer electronic currency system, is a
-complicated issue. Within the system, users are identified by
-public-keys only. An attacker wishing to de-anonymize its users will
-attempt to construct the one-to-many mapping between users and
-public-keys and associate information external to the system with the
-users. Bitcoin tries to prevent this attack by storing the mapping of
-a user to his or her public-keys on that user's node only and by
-allowing each user to generate as many public-keys as required. In
-this chapter we consider the topological structure of two networks
-derived from Bitcoin's public transaction history. We show that the
-two networks have a non-trivial topological structure, provide
-complementary views of the Bitcoin system and have implications for
-anonymity. We combine these structures with external information and
-techniques such as context discovery and flow analysis to investigate
-an alleged theft of Bitcoins, which, at the time of the theft, had a
-market value of approximately half a million U.S. dollars."
-</blockquote></p>
-
-<p>I hope these references can help kill the urban myth that Bitcoin
-is anonymous. It isn't really a good fit for illegal activites. Use
-cash if you need to stay anonymous, at least until regular DNA
-sampling of notes and coins become the norm. :)</p>

-activities, please send Bitcoin donations to my address

+ <div class="date">17th June 2014</div>
+ <div class="body"><p>The <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux
+project</a> provide an instruction manual for teachers, system
+administrators and other users that contain useful tips for setting up
+and maintaining a Debian Edu installation. This text is about how the
+text processing of this manual is handled in the project.</p>
+
+<p>One goal of the project is to provide information in the native
+language of its users, and for this we need to handle translations.
+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="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

-<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 <a href="http://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
