- <description><p>Wireless mesh networks are self organising and self healing
-networks that can be used to connect computers across small and large
-areas, depending on the radio technology used. Normal wifi equipment
-can be used to create home made radio networks, and there are several
-successful examples like
-<a href="http://www.freifunk.net/">Freifunk</a> and
-<a href="http://www.awmn.net/">Athens Wireless Metropolitan Network</a>
-(see
-<a href="http://en.wikipedia.org/wiki/List_of_wireless_community_networks_by_region#Greece">wikipedia
-for a large list</a>) around the globe. To give you an idea how it
-work, check out the nice overview of the Kiel Freifunk community which
-can be seen from their
-<a href="http://freifunk.in-kiel.de/ffmap/nodes.html">dynamically
-updated node graph and map</a>, where one can see how the mesh nodes
-automatically handle routing and recover from nodes disappearing.
-There is also a small community mesh network group in Oslo, Norway,
-and that is the main topic of this blog post.</p>
-
-<p>I've wanted to check out mesh networks for a while now, and hoped
-to do it as part of my involvement with the <a
-href="http://www.nuug.no/">NUUG member organisation</a> community, and
-my recent involvement in
-<a href="https://wiki.debian.org/FreedomBox">the Freedombox project</a>
-finally lead me to give mesh networks some priority, as I suspect a
-Freedombox should use mesh networks to connect neighbours and family
-when possible, given that most communication between people are
-between those nearby (as shown for example by research on Facebook
-communication patterns). It also allow people to communicate without
-any central hub to tap into for those that want to listen in on the
-private communication of citizens, which have become more and more
-important over the years.</p>
-
-<p>So far I have only been able to find one group of people in Oslo
-working on community mesh networks, over at the hack space
-<a href="http://hackeriet.no/">Hackeriet</a> at Husmania. They seem to
-have started with some Freifunk based effort using OLSR, called
-<a href="http://oslo.freifunk.net/index.php?title=Main_Page">the Oslo
-Freifunk project</a>, but that effort is now dead and the people
-behind it have moved on to a batman-adv based system called
-<a href="http://meshfx.org/trac">meshfx</a>. Unfortunately the wiki
-site for the Oslo Freifunk project is no longer possible to update to
-reflect this fact, so the old project page can't be updated to point to
-the new project. A while back, the people at Hackeriet invited people
-from the Freifunk community to Oslo to talk about mesh networks. I
-came across this video where Hans Jørgen Lysglimt interview the
-speakers about this talk (from
-<a href="https://www.youtube.com/watch?v=N2Kd7CLkhSY">youtube</a>:</p>

-<p><iframe width="420" height="315" src="https://www.youtube.com/embed/N2Kd7CLkhSY" frameborder="0" allowfullscreen></iframe></p>
-
-<p>I mentioned OLSR and batman-adv, which are mesh routing protocols.
-There are heaps of different protocols, and I am still struggling to
-figure out which one would be "best" for some definitions of best, but
-given that the community mesh group in Oslo is so small, I believe it
-is best to hook up with the existing one instead of trying to create a
-completely different setup, and thus this have decided to focus on
-batman-adv for now. It sure help me to know that the very cool
-<a href="http://www.servalproject.org/">Serval project in Australia</a>
-is using batman-adv as their meshing technology when it create a self
-organizing and self healing telephony system for disaster areas and
-less industrialized communities. Check out this cool video presenting
-that project (from
-<a href="https://www.youtube.com/watch?v=30qNfzJCQOA">youtube</a>:</p>
-
-<p><iframe width="560" height="315" src="https://www.youtube.com/embed/30qNfzJCQOA" frameborder="0" allowfullscreen></iframe></p>
-
-<p>According to the wikipedia page on
-<a href="http://en.wikipedia.org/wiki/Wireless_mesh_network">Wireless
-mesh network</a> there are around 70 competing schemes for routing
-packets across mesh networks, and OLSR, B.A.T.M.A.N. and
-B.A.T.M.A.N. advanced are protocols used by several free software
-based community mesh networks.</p>
-
-</p>The batman-adv protocol is a bit special, as it provide layer 2
-(as in ethernet ) routing, allowing ipv4 and ipv6 to work on the same
-network. One way to think about it is that it provide a mesh based
-vlan you can bridge to or handle like any other vlan connected to your
-computer. The required drivers are already in the Linux kernel at
-least since Debian Wheezy, and it is fairly easy to set up. A
-<a href="http://www.open-mesh.org/projects/batman-adv/wiki/Quick-start-guide">good
-introduction</a> is available from the Open Mesh project. These are
-the key settings needed to join the Oslo meshfx network:</p>
-
-<table>
-<tr><th>Setting</th><th>Value</th></tr>
-<tr><td>Protocol / kernel module</td><td>batman-adv</td></tr>
-<tr><td>ESSID</td><td>meshfx@hackeriet</td></tr>
-<td>Channel / Frequency</td><td>11 / 2462</td></tr>
-<td>Cell ID</td><td>02:BA:00:00:00:01</td>
-</table>
-
-<p>The reason for setting ad-hoc wifi Cell ID is to work around bugs
-in firmware used in wifi card and wifi drivers. (See a nice post from
-VillageTelco about
-"<a href="http://tiebing.blogspot.no/2009/12/ad-hoc-cell-splitting-re-post-original.html">Information
-about cell-id splitting, stuck beacons, and failed IBSS merges!</a>
-for details.) When these settings are activated and you have some
-other mesh node nearby, your computer will be connected to the mesh
-network and can communicate with any mesh node that is connected to
-any of the nodes in your network of nodes. :)</p>
-
-<p>My initial plan was to reuse my old Linksys WRT54GL as a mesh node,
-but that seem to be very hard, as I have not been able to locate a
-firmware supporting batman-adv. If anyone know how to use that old
-wifi access point with batman-adv these days, please let me know.</p>
-
-<p>If you find this project interesting and want to join, please join
-us on IRC, either channel
-<a href="irc://irc.freenode.net/#oslohackerspace">#oslohackerspace</a>
-or <a href="irc://irc.freenode.net/#nuug">#nuug</a> on
-irc.freenode.net.</p>
-
-<p>While investigating mesh networks in Oslo, I came across an old
-research paper from the university of Stavanger and Telenor Research
-and Innovation called
-<a href="http://folk.uio.no/paalee/publications/netrel-egeland-iswcs-2008.pdf">The
-reliability of wireless backhaul mesh networks</a> and elsewhere
-learned that Telenor have been experimenting with mesh networks at
-Grünerløkka in Oslo. So mesh networks are also interesting for
-commercial companies, even though Telenor discovered that it was hard
-to figure out a good business plan for mesh networking and as far as I
-know have closed down the experiment. Perhaps Telenor or others would
-be interested in a cooperation?</p>

+ <description><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 align="center"><img width="60%" src="http://people.skolelinux.org/pere/blog/images/2014-09-13-kapsch-sollihogda-crop.jpeg"></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>
+#!/bin/sh
+urlmap() {
+ sed \
+ -e 's/ / /g' -e 's/{/%7B/g' \

+
+Aktuelt ID-område 1-874 var riktig i datakatalogen da jeg laget
+scriptet. Det vil endre seg over tid. Skriptet listet så opp
+aktuelle typer i og rundt skibrua:

+</pre></blockquote>
+
+<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>

-<a href="https://www.youtube.com/watch?v=w-GgpdqgLFc">video on
-Youtube</a> showing how to install the standalone Debian Edu /
-Skolelinux profile. This is the profile intended for use at home or
-on laptops that should not be integrated into the provided network
-services (no central home directory, no Kerberos / LDAP directory etc,
-in other word a single user machine). The result is 11 minutes long,
-and show some user applications (seem to be rather randomly picked).
-Missed a few of my favorites like celestia, planets and chromium
-showing the <a href="http://www.zygotebody.com/">Zygote Body 3D model
-of the human body</a>, but I guess he did not know about those or find
-other programs more interesting. :) And the video do not show the

+ <title>Speeding up the Debian installer using eatmydata and dpkg-divert</title>

+ <description><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&nbsp;$program&nbsp;$@", 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
+installation. I did some more measurements using Debian Edu Jessie,
+and got these results. The time measured is the time stamp in
+/var/log/syslog between the "pkgsel: starting tasksel" and the
+"pkgsel: finishing up" lines, if you want to do the same measurement
+yourself. In Debian Edu, the tasksel dialog do not show up, and the
+timing thus do not depend on how quickly the user handle the tasksel
+dialog.</p>
+
+<p><table>
+
+<tr>
+<th>Machine/setup</th>
+<th>Original tasksel</th>
+<th>Optimised tasksel</th>
+<th>Reduction</th>
+</tr>
+

+</tr>
+
+</table></p>
+
+<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
+<ahref="https://bugs.debian.org/702711">bug #702711. An updated
+eatmydata package in Debian will solve it.</p>

- <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Finally__Debian_Edu_Wheezy_is_released_today_.html</guid>
- <pubDate>Sun, 29 Sep 2013 10:20:00 +0200</pubDate>
- <description><p>A few hours ago, the announcement for the first stable release of
-Debian Edu Wheezy went out from the Debian publicity team. The
-complete announcement text can be found at
-<a href="http://www.debian.org/News/2013/20130928">the Debian News
-section</a>, translated to several languages. Please check it out.</p>
-
-<p>There is one minor known problem that we will fix very soon. One
-can not install a amd64 Thin Client Server using PXE, as the /var/
-partition is too small. A workaround is to extend the partition (use
-lvresize + resize2fs in tty 2 while installing).</p>
+ <title>Good bye subkeys.pgp.net, welcome pool.sks-keyservers.net</title>

+ <pubDate>Wed, 10 Sep 2014 13:10:00 +0200</pubDate>
+ <description><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>

+ <description><p>Two years later, I am still not sure if it is legal here in Norway
+to use or publish a video in H.264 or MPEG4 format edited by the
+commercially licensed video editors, without limiting the use to
+create "personal" or "non-commercial" videos or get a license
+agreement with <a href="http://www.mpegla.com">MPEG LA</a>. If one
+want to publish and broadcast video in a non-personal or commercial
+setting, it might be that those tools can not be used, or that video
+format can not be used, without breaking their copyright license. I
+am not sure.
+<a href="http://people.skolelinux.org/pere/blog/Trenger_en_avtale_med_MPEG_LA_for___publisere_og_kringkaste_H_264_video_.html">Back
+then</a>, I found that the copyright license terms for Adobe Premiere
+and Apple Final Cut Pro both specified that one could not use the
+program to produce anything else without a patent license from MPEG
+LA. The issue is not limited to those two products, though. Other
+much used products like those from Avid and Sorenson Media have terms
+of use are similar to those from Adobe and Apple. The complicating
+factor making me unsure if those terms have effect in Norway or not is
+that the patents in question are not valid in Norway, but copyright
+licenses are.</p>

-<p>About Debian Edu and Skolelinux</p>
-
-<p>Debian Edu, also known as Skolelinux, is a Linux distribution based
-on Debian providing an out-of-the box environment of a completely
-configured school network. Immediately after installation a school
-server running all services needed for a school network is set up just
-waiting for users and machines being added via GOsa², a comfortable
-Web-UI. A netbooting environment is prepared using PXE, so after
-initial installation of the main server from CD or USB stick all other
-machines can be installed via the network. The provided school server
-provides LDAP database and Kerberos authentication service,
-centralized home directories, DHCP server, web proxy and many other
-services. The desktop contains more than 60 educational software
-packages and more are available from the Debian archive, and schools
-can choose between KDE, Gnome, LXDE and Xfce desktop environment.</p>
-
-<p>This is the seventh test release based on Debian Wheezy. Basically
-this is an updated and slightly improved version compared to the
-Squeeze release.</p>
-
-<p>Notes for upgrades from Alpha Prereleases</p>
-
-<p>Alpha based installations should reinstall or downgrade the
-versions of gosa and libpam-mklocaluser to the ones used in this beta
-release. Both alpha and beta0 based installations should reinstall or
-deal with gosa.conf manually; there are two options: (1) Keep
-gosa.conf and edit this file as outlined on the mailing list. (2)
-Accept the new version of gosa.conf and replace both contained admin
-password placeholders with the password hashes found in the old one
-(backup copy!). In both cases all users need to change their password
-to make sure a password is set for CIFS access to their home
-directory.</p>
-
-
-<p>cheers,
-<br> Holger</p>

- <pubDate>Tue, 10 Sep 2013 14:20:00 +0200</pubDate>
- <description><p>I was introduced to the
-<a href="http://www.freedomboxfoundation.org/">Freedombox project</a>
-in 2010, when Eben Moglen presented his vision about serving the need
-of non-technical people to keep their personal information private and
-within the legal protection of their own homes. The idea is to give
-people back the power over their network and machines, and return
-Internet back to its intended peer-to-peer architecture. Instead of
-depending on a central service, the Freedombox will give everyone
-control over their own basic infrastructure.</p>
-
-<p>I've intended to join the effort since then, but other tasks have
-taken priority. But this summers nasty news about the misuse of trust
-and privilege exercised by the "western" intelligence gathering
-communities increased my eagerness to contribute to a point where I
-actually started working on the project a while back.</p>
-
-<p>The <a href="https://alioth.debian.org/projects/freedombox/">initial
-Debian initiative</a> based on the vision from Eben Moglen, is to
-create a simple and cheap Debian based appliance that anyone can hook
-up in their home and get access to secure and private services and
-communication. The initial deployment platform have been the
-<a href="http://www.globalscaletechnologies.com/t-dreamplugdetails.aspx">Dreamplug</a>,
-which is a piece of hardware I do not own. So to be able to test what
-the current Freedombox setup look like, I had to come up with a way to install
-it on some hardware I do have access to. I have rewritten the
-<a href="https://github.com/NickDaly/freedom-maker">freedom-maker</a>
-image build framework to use .deb packages instead of only copying
-setup into the boot images, and thanks to this rewrite I am able to
-set up any machine supported by Debian Wheezy as a Freedombox, using
-the previously mentioned deb (and a few support debs for packages
-missing in Debian).</p>
-
-<p>The current Freedombox setup consist of a set of bootstrapping
-scripts
-(<a href="https://github.com/petterreinholdtsen/freedombox-setup">freedombox-setup</a>),
-and a administrative web interface
-(<a href="https://github.com/NickDaly/Plinth">plinth</a> + exmachina +
-withsqlite), as well as a privacy enhancing proxy based on
-<a href="http://packages.qa.debian.org/privoxy">privoxy</a>
-(freedombox-privoxy). There is also a web/javascript based XMPP
-client (<a href="http://packages.qa.debian.org/jwchat">jwchat</a>)
-trying (unsuccessfully so far) to talk to the XMPP server
-(<a href="http://packages.qa.debian.org/ejabberd">ejabberd</a>). The
-web interface is pluggable, and the goal is to use it to enable OpenID
-services, mesh network connectivity, use of TOR, etc, etc. Not much of
-this is really working yet, see
-<a href="https://github.com/NickDaly/freedombox-todos/blob/master/TODO">the
-project TODO</a> for links to GIT repositories. Most of the code is
-on github at the moment. The HTTP proxy is operational out of the
-box, and the admin web interface can be used to add/remove plinth
-users. I've not been able to do anything else with it so far, but
-know there are several branches spread around github and other places
-with lots of half baked features.</p>
-
-<p>Anyway, if you want to have a look at the current state, the
-following recipes should work to give you a test machine to poke
-at.</p>
-
-<p><strong>Debian Wheezy amd64</strong></p>
-
-<ol>
-
-<li>Fetch normal Debian Wheezy installation ISO.</li>
-<li>Boot from it, either as CD or USB stick.</li>
-<li><p>Press [tab] on the boot prompt and add this as a boot argument
-to the Debian installer:<p>
-<pre>url=<a href="http://www.reinholdtsen.name/freedombox/preseed-wheezy.dat">http://www.reinholdtsen.name/freedombox/preseed-wheezy.dat</a></pre></li>
-
-<li>Answer the few language/region/password questions and pick disk to
-install on.</li>
-
-<li>When the installation is finished and the machine have rebooted a
-few times, your Freedombox is ready for testing.</li>
-
-</ol>
-
-<p><strong>Raspberry Pi Raspbian</strong></p>
-
-<ol>
-
-<li>Fetch a Raspbian SD card image, create SD card.</li>
-<li>Boot from SD card, extend file system to fill the card completely.</li>
-<li><p>Log in and add this to /etc/sources.list:</p>
-<pre>
-deb <a href="http://www.reinholdtsen.name/freedombox/">http://www.reinholdtsen.name/freedombox</a> wheezy main
-</pre></li>
-<li><p>Run this as root:</p>
-<pre>
-wget -O - http://www.reinholdtsen.name/freedombox/BE1A583D.asc | \
- apt-key add -
-apt-get update
-apt-get install freedombox-setup
-/usr/lib/freedombox/setup
-</pre></li>
-<li>Reboot into your freshly created Freedombox.</li>
-
-</ol>
-
-<p>You can test it on other architectures too, but because the
-freedombox-privoxy package is binary, it will only work as intended on
-the architectures where I have had time to build the binary and put it
-in my APT repository. But do not let this stop you. It is only a
-short "<tt>apt-get source -b freedombox-privoxy</tt>" away. :)</p>
-
-<p>Note that by default Freedombox is a DHCP server on the
-192.168.1.0/24 subnet, so if this is your subnet be careful and turn
-off the DHCP server by running "<tt>update-rc.d isc-dhcp-server
-disable</tt>" as root.</p>
-
-<p>Please let me know if this works for you, or if you have any
-problems. We gather on the IRC channel
-<a href="irc://irc.debian.org:6667/%23freedombox">#freedombox</a> on
-irc.debian.org and the
-<a href="http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/freedombox-discuss">project
-mailing list</a>.</p>
-
-<p>Once you get your freedombox operational, you can visit
-<tt>http://your-host-name:8001/</tt> to see the state of the plint
-welcome screen (dead end - do not be surprised if you are unable to
-get past it), and next visit <tt>http://your-host-name:8001/help/</tt>
-to look at the rest of plinth. The default user is 'admin' and the
-default password is 'secret'.</p>

+ <description><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. &lt;Irony on&gt; And Linux
+isn't cool. It's software for freaks using the command line. &lt;Irony
+off&gt; 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>

- <title>Datalagringsdirektivet gjør at Oslo Høyre og Arbeiderparti ikke får min stemme i år</title>
- <link>http://people.skolelinux.org/pere/blog/Datalagringsdirektivet_gj_r_at_Oslo_H_yre_og_Arbeiderparti_ikke_f_r_min_stemme_i__r.html</link>

- <pubDate>Sun, 8 Sep 2013 20:40:00 +0200</pubDate>
- <description><p>I 2011 raderte et stortingsflertall bestående av Høyre og
-Arbeiderpartiet vekk en betydelig del av privatsfæren til det norske
-folk. Det ble vedtatt at det skulle registreres og lagres i et halvt
-år hvor alle som bærer på en mobiltelefon befinner seg, hvem de
-snakker med og hvor lenge de snakket sammen. Det skal også
-registreres hvem de sendte SMS-meldinger til, hvem en har sendt epost
-til, og hvilke nett-tjenere en besøkte. Saken er kjent som
-<a href="http://beta.holderdeord.no/issues/innfore-datalagringsdirektivet">Datalagringsdirektivet
-(DLD)</a>, og innebærer at alle innbyggerne og andre innenfor Norges
-grenser overvåkes døgnet rundt. Det ble i praksis innført brev og
-besøkskontroll av hele befolkningen. Rapporter fra de landene som
-allerede har innført slik total lagring av borgernes
-kommunikasjonsmønstre forteller at det ikke hjelper i
-kriminalitetsbekjempelsen. Den norske prislappen blir mange hundre
-millioner, uten at det ser ut til å bidra positivt til politiets
-arbeide. Jeg synes flere hundre millioner i stedet burde vært brukt
-på noe som kan dokumenteres å ha effekt i kriminalitetsbekjempelsen.
-Se mer på
-<a href="http://no.wikipedia.org/wiki/Datalagringsdirektivet">Wikipedia</a>
-og <a href="http://www.uhuru.biz/?cat=84">Jon Wessel-Aas</a>.</p>
-
-<p>Hva er problemet, tenkter du kanskje? Et åpenbart problem er at
-medienes kildevern i praksis blir radert ut. Den innsamlede
-informasjonen gjør det mulig å finne ut hvem som har snakket med
-journalister på telefon, SMS og epost, og hvem som har vært i nærheten
-av journalister så sant begge bar med seg en telefon. Et annet er at
-advokatvernet blir sterkt redusert, der politiet kan finne ut hvem
-som har snakket med en advokat når, eller vært i møter en med advokat.
-Et tredje er at svært personlig informasjon kan avledes fra hvilke
-nettsteder en har besøkt. Har en besøkt hivnorge.no,
-swingersnorge.com eller andre sider som kan brukes til avlede
-interesser som hører til privatsfæren, vil denne informasjonen være
-tilgjengelig takket være datalagringsdirektivet.</p>
-
-<p>De fleste partiene var mot, kun to partier stemte for. Høyre og
-Arbeiderpartiet. Og både Høyre og Arbeiderpartiet i Oslo har
-DLD-forkjempere på toppen av sine lister (har ikke sjekket de andre
-fylkene). Det er dermed helt uaktuelt for meg å stemme på disse
-partiene. Her er oversikten over partienes valglister i Oslo, med
-informasjon om hvem som stemte hva i første DLD-votering i Stortinget,
-basert på informasjon fra mine venner i
-<a href="http://beta.holderdeord.no/votes/1301946411e">Holder de
-Ord</a> samt <a href="http://data.stortinget.no/">data.stortinget.no</a>.

- <pubDate>Thu, 22 Aug 2013 09:30:00 +0200</pubDate>
- <description><p>The second wheezy based beta release of Debian Edu was wrapped up
-today, slightly delayed because of some bugs in the initial Windows
-integration fixes . This is the release announcement:</p>
-
-<p><strong>New features for Debian Edu 7.1+edu0~b1 released 2013-08-22</strong></p>
-
-<p>These are the release notes for Debian Edu / Skolelinux
-7.1+edu0~b1, based on Debian with codename "Wheezy".</p>
-
-<p><strong>About Debian Edu and Skolelinux</strong></p>
-
-<p><a href="http://www.skolelinux.org/">Debian Edu, also known as
-Skolelinux</a>, is a Linux distribution based on Debian providing an
-out-of-the box environment of a completely configured school
-network. Immediately after installation a school server running all
-services needed for a school network is set up just waiting for users
-and machines being added via GOsa², a comfortable Web-UI. A netbooting
-environment is prepared using PXE, so after initial installation of
-the main server from CD or USB stick all other machines can be
-installed via the network. The provided school server provides LDAP
-database and Kerberos authentication service, centralized home
-directories, DHCP server, web proxy and many other services. The
-desktop contains
-<a href="http://people.skolelinux.org/pere/blog/Educational_applications_included_in_Debian_Edu___Skolelinux__the_screenshot_collection____.html">more
-than 60 educational software packages</a> and more are available from
-the Debian archive, and schools can choose between KDE, Gnome, LXDE
-and Xfce desktop environment.</p>
-
-<p>This is the sixth test release based on Debian Wheezy. Basically this
-is an updated and slightly improved version compared to the Squeeze
-release.</p>
-
-<p>ALERT: Alpha based installations should reinstall or downgrade the
-versions of gosa and libpam-mklocaluser to the ones used in this beta
-release. Both alpha and beta0 based installations should reinstall or
-deal with gosa.conf manually; there are two options: (1) Keep
-gosa.conf and edit this file as outlined
-<a href="http://lists.debian.org/debian-edu/2013/08/msg00127.html">on
-the mailing list</a>. (2) Accept the new version of gosa.conf and
-replace both contained admin password placeholders with the password
-hashes found in the old one (backup copy!). In both cases every user
-need to change their their password to make sure a password is set for
-CIFS access to their home directory.</p>
-
-<p><strong>Software updates</strong></p>
-
-<ul>
-
-<li>Added ssh askpass packages to default installation, to ensure ssh
- work also without a attached tty.</li>
-<li>Add the command-not-found package to the default installation to
- make it easier to figure out where to find missing command line
- tools. Please note, that the command 'update-command-not-found'
- has to be run as root to actually make it useful (internet access
- required).</li>
-
-</ul>
-
-<p><strong>Other changes</strong></p>
-
-<ul>
-
-<li>Adjusted the USB stick ISO image build to include every tool
-needed for desktop=xfce installations.</li>
-<li>Adjust thin-client-server task to work when installing from USB
-stick ISO image.</li>
-<li>Made new grub artwork (changed png from indexed to RGB format).</li>
-<li>Minor cleanup in the CUPS setup.</li>
-<li>Make sure that bootstrapping of the Samba domain really happens
- during installation of the main server and adjust SID handling to
- cope with this.</li>
-<li>Make Samba passwords changeable (again) via GOsa².</li>
-<li>Fix generation of LM and NT password hashes via GOsa² to avoid
- empty password hashes.</li>
-<li>Adapted Samba machine domain joining to latest change in the
- smbldap-tools Perl package, fixing bugs blocking Windows machines
- from joining the Samba domain.</li>
-
-</ul>
-
-<p><strong>Known issues</strong></p>
-
-<ul>
-
-<li>KDE fails to understand the wpad.dat file provided, causing it to
- not use the http proxy as it should.</li>
-<li>Chromium also fails to use the proxy when using the KDE desktop
- (using the KDE configuration).</li>
-
-</ul>

+ <description><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>
+
+<p>To learn more, check out
+<a href="http://packages.qa.debian.org/d/debian-edu-doc.html">the
+debian-edu-doc package</a>,
+<a href="https://wiki.debian.org/DebianEdu/Documentation/Wheezy/">the
+manual on the wiki</a> and
+<a href="https://wiki.debian.org/DebianEdu/Documentation/Wheezy/Translations">the
+translation instructions</a> in the manual.</p>

+ <description><p>Jeg har fortsatt behov for å kunne laste ned innslag fra NRKs
+nettsted av og til for å se senere når jeg ikke er på nett, men
+<a href="http://people.skolelinux.org/pere/blog/Hvordan_enkelt_laste_ned_filmer_fra_NRK.html">min
+oppskrift fra 2011</a> sluttet å fungere da NRK byttet
+avspillermetode. I dag fikk jeg endelig lett etter oppdatert løsning,
+og jeg er veldig glad for å fortelle at den enkleste måten å laste ned
+innslag er å bruke siste versjon 2014.06.07 av
+<a href="http://rg3.github.io/youtube-dl/">youtube-dl</a>. Støtten i
+youtube-dl <a href="https://github.com/rg3/youtube-dl/issues/2980">kom
+inn for 23 dager siden</a> og
+<a href="http://packages.qa.debian.org/y/youtube-dl.html">versjonen i
+Debian</a> fungerer fint også som backport til Debian Wheezy. Det er
+et lite problem, det håndterer kun URLer med små bokstaver, men hvis
+en har en URL med store bokstaver kan en bare gjøre alle store om til
+små bokstaver for å få youtube-dl til å laste ned. Rapporterte
+nettopp
+<a href="https://github.com/rg3/youtube-dl/issues/2980">problemet til
+utviklerne</a>, og antar de får fikset det snart.</p>
+
+<p>Dermed er alt klart til å laste ned dokumentarene om
+<a href="http://tv.nrk.no/program/KOID23005014/usas-hemmelige-avlytting">USAs
+hemmelige avlytting</a> og
+<a href="http://tv.nrk.no/program/KOID23005114/selskapene-bak-usas-avlytting">Selskapene
+bak USAs avlytting</a>, i tillegg til
+<a href="http://tv.nrk.no/program/KOID20005814/et-moete-med-edward-snowden">intervjuet
+med Edward Snowden gjort av den tyske tv-kanalen ARD</a>. Anbefaler
+alle å se disse, sammen med
+<a href="http://media.ccc.de/browse/congress/2013/30C3_-_5713_-_en_-_saal_2_-_201312301130_-_to_protect_and_infect_part_2_-_jacob.html">foredraget
+til Jacob Appelbaum på siste CCC-konferanse</a>, for å forstå mer om
+hvordan overvåkningen av borgerne brer om seg.</p>
+
+<p>Takk til gode venner på foreningen NUUGs IRC-kanal
+<a href="irc://irc.freenode.net/%23nuug">#nuug på irc.freenode.net</a>
+for tipsene som fikk meg i mål</a>.</p>
+
+<p><strong>Oppdatering 2014-06-17</strong>: Etter at jeg publiserte
+denne, ble jeg tipset om bloggposten
+"<a href="http://ingvar.blog.redpill-linpro.com/2012/05/31/downloading-hd-content-from-tv-nrk-no/">Downloading
+HD content from tv.nrk.no</a>" av Ingvar Hagelund, som har alternativ
+implementasjon og tips for å lage mkv-fil med undertekstene inkludert.
+Kanskje den passer bedre for deg? I tillegg ble feilen i youtube-dl
+ble fikset litt senere ut på dagen i går, samt at youtube-dl fikk
+støtte for å laste ned undertitler. Takk til Anders Einar Hilden for
+god innsats og youtube-dl-utviklerne for rask respons.</p>

- <title>Intel 180 SSD disk with Lenovo firmware can not use Intel firmware</title>

- <description><p>Earlier, I reported about
-<a href="http://people.skolelinux.org/pere/blog/How_to_fix_a_Thinkpad_X230_with_a_broken_180_GB_SSD_disk.html">my
-problems using an Intel SSD 520 Series 180 GB disk</a>. Friday I was
-told by IBM that the original disk should be thrown away. And as
-there no longer was a problem if I bricked the firmware, I decided
-today to try to install Intel firmware to replace the Lenovo firmware
-currently on the disk.</p>
-
-<p>I searched the Intel site for firmware, and found
-<a href="https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&ProdId=3472&DwnldID=18363&ProductFamily=Solid-State+Drives+and+Caching&ProductLine=Intel%c2%ae+High+Performance+Solid-State+Drive&ProductProduct=Intel%c2%ae+SSD+520+Series+(180GB%2c+2.5in+SATA+6Gb%2fs%2c+25nm%2c+MLC)&lang=eng">issdfut_2.0.4.iso</a>
-(aka Intel SATA Solid-State Drive Firmware Update Tool) which
-according to the site should contain the latest firmware for SSD
-disks. I inserted the broken disk in one of my spare laptops and
-booted the ISO from a USB stick. The disk was recognized, but the
-program claimed the newest firmware already were installed and refused
-to insert any Intel firmware. So no change, and the disk is still
-unable to handle write load. :( I guess the only way to get them
-working would be if Lenovo releases new firmware. No idea how likely
-that is. Anyway, just blogging about this test for completeness. I
-got a working Samsung disk, and see no point in spending more time on
-the broken disks.</p>

- <title>90 percent done with the Norwegian draft translation of Free Culture</title>
- <link>http://people.skolelinux.org/pere/blog/90_percent_done_with_the_Norwegian_draft_translation_of_Free_Culture.html</link>
- <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/90_percent_done_with_the_Norwegian_draft_translation_of_Free_Culture.html</guid>

- <description><p>It has been a while since my last update. Since last summer, I
-have worked on a Norwegian
-<a href="http://www.docbook.org/">docbook</a> version of the 2004 book
-<a href="http://free-culture.cc/">Free Culture</a> by Lawrence Lessig,
-to get a Norwegian text explaining the problems with the copyright
-law. Yesterday, I finally broken the 90% mark, when counting the
-number of strings to translate. Due to real life constraints, I have
-not had time to work on it since March, but when the summer broke out,
-I found time to work on it again. Still lots of work left, but the
-first draft is nearing completion. I created a graph to show the
-progress of the translation:</p>
-
-<p><img width="80%" align="center" src="https://github.com/petterreinholdtsen/free-culture-lessig/raw/master/progress.png"></p>
-
-<p>When the first draft is done, the translated text need to be
-proof read, and the remaining formatting problems with images and SVG
-drawings need to be fixed. There are probably also some index entries
-missing that need to be added. This can be done by comparing the
-index entries listed in the SiSU version of the book, or comparing the
-English docbook version with the paper version. Last, the colophon
-page with ISBN numbers etc need to be wrapped up before the release is
-done. I should also figure out how to get correct Norwegian sorting
-of the index pages. All docbook tools I have tried so far (xmlto,
-docbook-xsl, dblatex) get the order of symbols and the special
-Norwegian letters ÆØÅ wrong.</p>
-
-<p>There is still need for translators and people with docbook
-knowledge, to be able to get a good looking book (I still struggle
-with dblatex, xmlto and docbook-xsl) as well as to do the draft
-translation and proof reading. And I would like the figures to be
-redrawn as SVGs to make it easy to translate them. Any SVG master
-around? There are also some legal terms that are unfamiliar to me.
-If you want to help, please get in touch with me, and check out the
-project files currently available from
-<a href="https://github.com/petterreinholdtsen/free-culture-lessig">github</a>.</p>
-
-<p>If you are curious what the translated book currently look like,
-the updated
-<a href="https://github.com/petterreinholdtsen/free-culture-lessig/blob/master/archive/freeculture.nb.pdf?raw=true">PDF</a>
-and
-<a href="https://github.com/petterreinholdtsen/free-culture-lessig/blob/master/archive/freeculture.nb.epub?raw=true">EPUB</a>
-are published on github. The HTML version is published as well, but
-github hand it out with MIME type text/plain, confusing browsers, so I
-saw no point in linking to that version.</p>
+<p>If you know of any free software car computer system supporting
+some or all of these features, please let me know.</p>
