- <description><p>If one of the points of switching to a new init system in Debian is
-<a href="http://thomas.goirand.fr/blog/?p=147">to get rid of huge
-init.d scripts</a>, I doubt we need to switch away from sysvinit and
-init.d scripts at all. Here is an example init.d script, ie a rewrite
-of /etc/init.d/rsyslog:</p>
-
-<p><pre>
-#!/lib/init/init-d-script
-### BEGIN INIT INFO
-# Provides: rsyslog
-# Required-Start: $remote_fs $time
-# Required-Stop: umountnfs $time
-# X-Stop-After: sendsigs
-# Default-Start: 2 3 4 5
-# Default-Stop: 0 1 6
-# Short-Description: enhanced syslogd
-# Description: Rsyslog is an enhanced multi-threaded syslogd.
-# It is quite compatible to stock sysklogd and can be
-# used as a drop-in replacement.
-### END INIT INFO
-DESC="enhanced syslogd"
-DAEMON=/usr/sbin/rsyslogd
-</pre></p>
-
-<p>Pretty minimalistic to me... For the record, the original sysv-rc
-script was 137 lines, and the above is just 15 lines, most of the meta
-info/comments.</p>
-
-<p>How to do this, you ask? Well, one create a new script
-/lib/init/init-d-script looking something like this:
-
-<p><pre>
-#!/bin/sh
-
-# Define LSB log_* functions.
-# Depend on lsb-base (>= 3.2-14) to ensure that this file is present
-# and status_of_proc is working.
-. /lib/lsb/init-functions
-
-#
-# Function that starts the daemon/service
-
-#
-do_start()
-{
- # Return
- # 0 if daemon has been started
- # 1 if daemon was already running
- # 2 if daemon could not be started
- start-stop-daemon --start --quiet --pidfile $PIDFILE --exec $DAEMON --test > /dev/null \
- || return 1
- start-stop-daemon --start --quiet --pidfile $PIDFILE --exec $DAEMON -- \
- $DAEMON_ARGS \
- || return 2
- # Add code here, if necessary, that waits for the process to be ready
- # to handle requests from services started subsequently which depend
- # on this one. As a last resort, sleep for some time.
-}
-
-#
-# Function that stops the daemon/service
-#
-do_stop()
-{
- # Return
- # 0 if daemon has been stopped
- # 1 if daemon was already stopped
- # 2 if daemon could not be stopped
- # other if a failure occurred
- start-stop-daemon --stop --quiet --retry=TERM/30/KILL/5 --pidfile $PIDFILE --name $NAME
- RETVAL="$?"
- [ "$RETVAL" = 2 ] && return 2
- # Wait for children to finish too if this is a daemon that forks
- # and if the daemon is only ever run from this initscript.
- # If the above conditions are not satisfied then add some other code
- # that waits for the process to drop all resources that could be
- # needed by services started subsequently. A last resort is to
- # sleep for some time.
- start-stop-daemon --stop --quiet --oknodo --retry=0/30/KILL/5 --exec $DAEMON
- [ "$?" = 2 ] && return 2
- # Many daemons don't delete their pidfiles when they exit.
- rm -f $PIDFILE
- return "$RETVAL"
-}
-
-#
-# Function that sends a SIGHUP to the daemon/service

+ <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Testing_sysvinit_from_experimental_in_Debian_Hurd.html</guid>
+ <pubDate>Mon, 3 Feb 2014 13:40:00 +0100</pubDate>
+ <description><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
+pkill pfinet
+pkill devnode
+dhclient -v /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 &lt;&lt;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 &lt;&lt;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>It is based on /etc/init.d/skeleton, and could be improved quite a
-lot. I did not really polish the approach, so it might not always
-work out of the box, but you get the idea. I did not try very hard to
-optimize it nor make it more robust either.</p>
+</pre></blockquote></p>
-<p>A better argument for switching init system in Debian than reducing
-the size of init scripts (which is a good thing to do anyway), is to
-get boot system that is able to handle the kernel events sensibly and
-robustly, and do not depend on the boot to run sequentially. The boot
-and the kernel have not behaved sequentially in year.</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>

+ <description><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>
+
+<p>As usual, if you use Bitcoin and want to show your support of my
+activities, please send Bitcoin donations to my address

- <description><p>The
-<a href="http://packages.qa.debian.org/v/vmdebootstrap.html">vmdebootstrap</a>
-program is a a very nice system to create virtual machine images. It
-create a image file, add a partition table, mount it and run
-debootstrap in the mounted directory to create a Debian system on a
-stick. Yesterday, I decided to try to teach it how to make images for
-<a href="https://wiki.debian.org/RaspberryPi">Raspberry Pi</a>, as part
-of a plan to simplify the build system for
-<a href="https://wiki.debian.org/FreedomBox">the FreedomBox
-project</a>. The FreedomBox project already uses vmdebootstrap for
-the virtualbox images, but its current build system made multistrap
-based system for Dreamplug images, and it is lacking support for
-Raspberry Pi.</p>
-
-<p>Armed with the knowledge on how to build "foreign" (aka non-native
-architecture) chroots for Raspberry Pi, I dived into the vmdebootstrap
-code and adjusted it to be able to build armel images on my amd64
-Debian laptop. I ended up giving vmdebootstrap five new options,
-allowing me to replicate the image creation process I use to make
-<a href="http://people.skolelinux.org/pere/blog/A_Raspberry_Pi_based_batman_adv_Mesh_network_node.html">Debian
-Jessie based mesh node images for the Raspberry Pi</a>. First, the
-<tt>--foreign /path/to/binfm_handler</tt> option tell vmdebootstrap to
-call debootstrap with --foreign and to copy the handler into the
-generated chroot before running the second stage. This allow
-vmdebootstrap to create armel images on an amd64 host. Next I added
-two new options <tt>--bootsize size</tt> and <tt>--boottype
-fstype</tt> to teach it to create a separate /boot/ partition with the
-given file system type, allowing me to create an image with a vfat
-partition for the /boot/ stuff. I also added a <tt>--variant
-variant</tt> option to allow me to create smaller images without the
-Debian base system packages installed. Finally, I added an option
-<tt>--no-extlinux</tt> to tell vmdebootstrap to not install extlinux
-as a boot loader. It is not needed on the Raspberry Pi and probably
-most other non-x86 architectures. The changes were accepted by the
-upstream author of vmdebootstrap yesterday and today, and is now
-available from
-<a href="http://git.liw.fi/cgi-bin/cgit/cgit.cgi/vmdebootstrap/">the
-upstream project page</a>.</p>
-
-<p>To use it to build a Raspberry Pi image using Debian Jessie, first
-create a small script (the customize script) to add the non-free
-binary blob needed to boot the Raspberry Pi and the APT source
-list:</p>
-
-<p><pre>
-#!/bin/sh
-set -e # Exit on first error
-rootdir="$1"
-cd "$rootdir"
-cat &lt;&lt;EOF > etc/apt/sources.list
-deb http://http.debian.net/debian/ jessie main contrib non-free
-EOF
-# Install non-free binary blob needed to boot Raspberry Pi. This
-# install a kernel somewhere too.
-wget https://raw.github.com/Hexxeh/rpi-update/master/rpi-update \
- -O $rootdir/usr/bin/rpi-update
-chmod a+x $rootdir/usr/bin/rpi-update
-mkdir -p $rootdir/lib/modules
-touch $rootdir/boot/start.elf
-chroot $rootdir rpi-update
-</pre></p>
-
-<p>Next, fetch the latest vmdebootstrap script and call it like this
-to build the image:</p>
-
-<pre>
-sudo ./vmdebootstrap \
- --variant minbase \
- --arch armel \
- --distribution jessie \
- --mirror http://http.debian.net/debian \
- --image test.img \
- --size 600M \
- --bootsize 64M \
- --boottype vfat \
- --log-level debug \
- --verbose \
- --no-kernel \
- --no-extlinux \
- --root-password raspberry \
- --hostname raspberrypi \
- --foreign /usr/bin/qemu-arm-static \
- --customize `pwd`/customize \
- --package netbase \
- --package git-core \
- --package binutils \
- --package ca-certificates \
- --package wget \
- --package kmod
-</pre></p>
-
-<p>The list of packages being installed are the ones needed by
-rpi-update to make the image bootable on the Raspberry Pi, with the
-exception of netbase, which is needed by debootstrap to find
-/etc/hosts with the minbase variant. I really wish there was a way to
-set up an Raspberry Pi using only packages in the Debian archive, but
-that is not possible as far as I know, because it boots from the GPU
-using a non-free binary blob.</p>
-
-<p>The build host need debootstrap, kpartx and qemu-user-static and
-probably a few others installed. I have not checked the complete
-build dependency list.</p>
-
-<p>The resulting image will not use the hardware floating point unit
-on the Raspberry PI, because the armel architecture in Debian is not
-optimized for that use. So the images created will be a bit slower
-than <a href="http://www.raspbian.org/">Raspbian</a> based images.</p>

+ <description><p><a href="http://www.coverity.com/">Coverity</a> is a nice tool to
+find problems in C, C++ and Java code using static source code
+analysis. It can detect a lot of different problems, and is very
+useful to find memory and locking bugs in the error handling part of
+the source. The company behind it provide
+<a href="https://scan.coverity.com/">check of free software projects as
+a community service</a>, and many hundred free software projects are
+already checked. A few days ago I decided to have a closer look at
+the Coverity system, and discovered that the
+<a href="http://www.gnu.org/software/gnash/">gnash</a> and
+<a href="http://sourceforge.net/projects/ipmitool/">ipmitool</a>
+projects I am involved with was already registered. But these are
+fairly big, and I would also like to have a small and easy project to
+check, and decided to <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
+the future end up in a library. Having fixed all defects and added
+<a href="https://lists.alioth.debian.org/mailman/listinfo/chrpath-devel">a

- <description><p>De siste måneders eksponering av
-<a href="http://www.aftenposten.no/nyheter/uriks/Her-er-Edvard-Snowdens-mest-omtalte-avsloringer-7351734.html">den
-totale overvåkningen som foregår i den vestlige verden dokumenterer
-hvor sårbare vi er</a>. Men det slår meg at de som er mest sårbare
-for dette, myndighetspersoner på alle nivåer, neppe har innsett at de
-selv er de mest interessante personene å lage profiler på, for å kunne
-påvirke dem.</p>
-
-<p>For å ta et lite eksempel: Stortingets nettsted,
-<a href="http://www.stortinget.no/">www.stortinget.no</a> (og
-forsåvidt også
-<a href="http://data.stortinget.no/">data.stortinget.no</a>),
-inneholder informasjon om det som foregår på Stortinget, og jeg antar
-de største brukerne av informasjonen der er representanter og
-rådgivere på Stortinget. Intet overraskende med det. Det som derimot
-er mer skjult er at Stortingets nettsted bruker
-<a href="http://en.wikipedia.org/wiki/Google_Analytics">Google
-Analytics</a>, hvilket gjør at enhver som besøker nettsidene der også
-rapporterer om besøket via Internett-linjer som passerer Sverige,
-England og videre til USA. Det betyr at informasjon om ethvert besøk
-på stortingets nettsider kan snappes opp av svensk, britisk og USAs
-etterretningsvesen. De kan dermed holde et øye med hvilke
-Stortingssaker stortingsrepresentantene synes er interessante å sjekke
-ut, og hvilke sider rådgivere og andre på stortinget synes er
-interessant å besøke, når de gjør det og hvilke andre representanter
-som sjekker de samme sidene omtrent samtidig. Stortingets bruk av
-Google Analytics gjør det dermed enkelt for utenlands etteretning å
-spore representantenes aktivitet og interesse. Hvis noen av
-representantene bruker Google Mail eller noen andre tjenestene som
-krever innlogging, så vil det være enda enklere å finne ut nøyaktig
-hvilke personer som bruker hvilke nettlesere og dermed knytte
-informasjonen opp til enkeltpersoner på Stortinget.</p>
-
-<p>Og jo flere nettsteder som bruker Google Analytics, jo bedre
-oversikt over stortingsrepresentantenes lesevaner og interesse blir
-tilgjengelig for svensk, britisk og USAs etterretning. Hva de kan
-bruke den informasjonen til overlater jeg til leseren å undres
-over.</p>

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

- <title>A Raspberry Pi based batman-adv Mesh network node</title>
- <link>http://people.skolelinux.org/pere/blog/A_Raspberry_Pi_based_batman_adv_Mesh_network_node.html</link>
- <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/A_Raspberry_Pi_based_batman_adv_Mesh_network_node.html</guid>
- <pubDate>Mon, 21 Oct 2013 11:40:00 +0200</pubDate>
- <description><p>The last few days I have been experimenting with
-<a href="http://www.open-mesh.org/projects/batman-adv/wiki">the
-batman-adv mesh technology</a>. I want to gain some experience to see
-if it will fit <a href="https://wiki.debian.org/FreedomBox">the
-Freedombox project</a>, and together with my neighbors try to build a
-mesh network around the park where I live. Batman-adv is a layer 2
-mesh system ("ethernet" in other words), where the mesh network appear
-as if all the mesh clients are connected to the same switch.</p>
-
-<p>My hardware of choice was the Linksys WRT54GL routers I had lying
-around, but I've been unable to get them working with batman-adv. So
-instead, I started playing with a
-<a href="http://www.raspberrypi.org/">Raspberry Pi</a>, and tried to
-get it working as a mesh node. My idea is to use it to create a mesh
-node which function as a switch port, where everything connected to
-the Raspberry Pi ethernet plug is connected (bridged) to the mesh
-network. This allow me to hook a wifi base station like the Linksys
-WRT54GL to the mesh by plugging it into a Raspberry Pi, and allow
-non-mesh clients to hook up to the mesh. This in turn is useful for
-Android phones using <a href="http://servalproject.org/">the Serval
-Project</a> voip client, allowing every one around the playground to
-phone and message each other for free. The reason is that Android
-phones do not see ad-hoc wifi networks (they are filtered away from
-the GUI view), and can not join the mesh without being rooted. But if
-they are connected using a normal wifi base station, they can talk to
-every client on the local network.</p>
-
-<p>To get this working, I've created a debian package
-<a href="https://github.com/petterreinholdtsen/meshfx-node">meshfx-node</a>
-and a script
-<a href="https://github.com/petterreinholdtsen/meshfx-node/blob/master/build-rpi-mesh-node">build-rpi-mesh-node</a>
-to create the Raspberry Pi boot image. I'm using Debian Jessie (and
-not Raspbian), to get more control over the packages available.
-Unfortunately a huge binary blob need to be inserted into the boot
-image to get it booting, but I'll ignore that for now. Also, as
-Debian lack support for the CPU features available in the Raspberry
-Pi, the system do not use the hardware floating point unit. I hope
-the routing performance isn't affected by the lack of hardware FPU
-support.</p>
-
-<p>To create an image, run the following with a sudo enabled user
-after inserting the target SD card into the build machine:</p>
-
-<p><pre>
-% wget -O build-rpi-mesh-node \
- https://raw.github.com/petterreinholdtsen/meshfx-node/master/build-rpi-mesh-node
-% sudo bash -x ./build-rpi-mesh-node > build.log 2>&1
-% dd if=/root/rpi/rpi_basic_jessie_$(date +%Y%m%d).img of=/dev/mmcblk0 bs=1M
-%
-</pre></p>
-
-<p>Booting with the resulting SD card on a Raspberry PI with a USB
-wifi card inserted should give you a mesh node. At least it does for
-me with a the wifi card I am using. The default mesh settings are the
-ones used by the Oslo mesh project at Hackeriet, as I mentioned in
-<a href="http://people.skolelinux.org/pere/blog/Oslo_community_mesh_network___with_NUUG_and_Hackeriet_at_Hausmania.html">an
-earlier blog post about this mesh testing</a>.</p>
-
-<p>The mesh node was not horribly expensive either. I bought
-everything over the counter in shops nearby. If I had ordered online
-from the lowest bidder, the price should be significantly lower:</p>
-
-<p><table>
-
-<tr><th>Supplier</th><th>Model</th><th>NOK</th></tr>
-<tr><td>Teknikkmagasinet</td><td>Raspberry Pi model B</td><td>349.90</td></tr>
-<tr><td>Teknikkmagasinet</td><td>Raspberry Pi type B case</td><td>99.90</td></tr>
-<tr><td>Lefdal</td><td>Jensen Air:Link 25150</td><td>295.-</td></tr>
-<tr><td>Clas Ohlson</td><td>Kingston 16 GB SD card</td><td>199.-</td></tr>
-<tr><td>Total cost</td><td></td><td>943.80</td></tr>
-
-</table></p>
-
-<p>Now my mesh network at home consist of one laptop in the basement
-connected to my production network, one Raspberry Pi node on the 1th
-floor that can be seen by my neighbor across the park, and one
-play-node I use to develop the image building script. And some times
-I hook up my work horse laptop to the mesh to test it. I look forward
-to figuring out what kind of latency the batman-adv setup will give,
-and how much packet loss we will experience around the park. :)</p>

+ <description><p>Helga 18. og 19. januar 2014 arrangeres
+<a href="http://makerfaireoslo.no/no/program/dugnadsnett">Oslo Maker
+Faire</a>, og <a href="http://www.dugnadsnett.no/">Dugnadsnett for
+alle</a> har fått plass! Planen er å ha et bord med en plakat der vi
+forteller om hva Dugnadsnett for alle er for noe, og et lite verksted
+der vi hjelper folk som er interessert i å få opp sin egen mesh-node.
+Jeg gleder meg til å se hvordan prosjektet blir mottatt der.</p>
+
+<p>Målet med dugnadsnett for alle i Oslo er å få på plass et datanett
+for kommunikasjon ved hjelp av radio-repeaterstasjoner (kalt
+mesh-noder) som gjør at en kan direkte kommunisere med slekt, venner
+og bekjente i Oslo via andre som deltar i dugnadsnettet, samt gjøre
+det mulig komme ut på internett via dugnadsnettet. Første delmål er å
+kunne sende SMS-meldinger vha. IP-telefoni løsningen
+<a href="http://www.servalproject.org/">Serval project</a> mellom
+deltagerne i Dugnadsnett for alle i Oslo. Formålet er å ta tilbake
+kontrollen over egen nett-infrastruktur og gjøre det dyrere å bedrive
+massiv innsamling av informasjon om borgernes bruk av datanett.</p>
+
+<p>Høres dette interessant ut? Bli med på prosjektet, fortell oss
+hvor du kunne tenke deg å sette opp en radio-repeater (slik at folk i
+nærheten kan finne hverandre ved hjelp av
+<a href="http://flynor.net/mesh/mesh.php">kartet over planlagte og
+eksisterende radio-repeatere</A>), bli med på epostlisten
+<a href="http://lists.nuug.no/mailman/listinfo/dugnadsnett">dugnadsnett

+<a href="irc://irc.freenode.net/#dugnadsnett.no">IRC-kanalen
+#dugnadsnett.no</a>. Så langt er det planlagt over 40
+radio-repeatere, med VPN-forbindelser via Internet for å la de delene
+av nettet som ikke når hverandre via radio kunne snakke med hverandre
+likevel.</p>

+ <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Klaus_Knopper.html</guid>
+ <pubDate>Fri, 6 Dec 2013 09:50:00 +0100</pubDate>
+ <description><p>It has been a while since I managed to publish the last interview,
+but the <a href="http://www.skolelinux.org/">Debian Edu /
+Skolelinux</a> community is still going strong, and yesterday we even
+had a new school administrator show up on
+<a href="irc://irc.debian.org/#debian-edu">#debian-edu</a> to share
+his success story with installing Debian Edu at their school. This
+time I have been able to get some helpful comments from the creator of
+Knoppix, Klaus Knopper, who was involved in a Skolelinux project in
+Germany a few years ago.</p>
+
+<p><strong>Who are you, and how do you spend your days?</strong></p>
+
+<p>I am Klaus Knopper. I have a master degree in electrical
+engineering, and is currently professor in information management at
+the university of applied sciences Kaiserslautern / Germany and
+freelance Open Source software developer and consultant.</p>
+
+<p>All of this is pretty much of the work I spend my days with. Apart
+from teaching, I'm also conducting some more or less experimental
+projects like the <a href="http://www.knoppix.org">Knoppix GNU/Linux live
+system</a> (Debian-based like Skolelinux),
+<a href="http://www.knopper.net/knoppix-adriane/index-en.html">ADRIANE</a>
+(a blind-friendly talking desktop system) and
+<a href="http://www.knopper.net/linbo/index-en.html">LINBO</a>
+(Linux-based network boot console, a fast remote install and repair
+system supporting various operating systems).</p>
+
+<p><strong>How did you get in contact with the Skolelinux / Debian Edu
+project?</strong></p>
+
+<p>The credit for this have to go to Kurt Gramlich, who is the German
+coordinator for Skolelinux. We were looking for an all-in-one open
+source community-supported distribution for schools, and Kurt
+introduced us to Skolelinux for this purpose.</p>
+
+<p><strong>What do you see as the advantages of Skolelinux / Debian
+Edu?</strong></p>
+
+<ul>
+ <li>Quick installation,</li>
+ <li>works (almost) out of the box,</li>
+ <li>contains many useful software packages for teaching and learning,</li>
+ <li>is a purely community-based distro and not controlled by a
+ single company,</li>
+ <li>has a large number of supporters and teachers who share their
+ experience and problem solutions.</li>
+</ul>
+
+<p><strong>What do you see as the disadvantages of Skolelinux / Debian
+Edu?</strong></p>
+
+<ul>
+ <li>Skolelinux is - as we had to learn - not easily upgradable to
+ the next version. Opposed to its genuine Debian base, upgrading to
+ a new version means a full new installation from scratch to get it
+ working again reliably.
+
+ <li>Skolelinux is based on Debian/stable, and therefore always a
+ little outdated in terms of program versions compared to Edubuntu or
+ similar educational Linux distros, which rather use Debian/testing
+ as their base.
+
+ <li>Skolelinux has some very self-opinionated and stubborn default
+ configuration which in my opinion adds unnecessary complexity and is
+ not always suitable for a schools needs, the preset network
+ configuration is actually a core definition feature of Skolelinux
+ and not easy to change, so schools sometimes have to change their
+ network configuration to make it "Skolelinux-compatible".
+
+ <li>Some proposed extensions, which were made available as
+ contribution, like secure examination mode and lecture material
+ distribution and collection, were not accepted into the mainline
+ Skolelinux development and are now not easy to maintain in the
+ future because of Skolelinux somewhat undeterministic update
+ schemes.</li>
+
+ <li>Skolelinux has only a very tiny number of base developers
+ compared to Debian.</li>
+
+</ul>
+
+<p>For these reasons and experience from our project, I would now
+rather consider using plain Debian for schools next time, until
+Skolelinux is more closely integrated into Debian and becomes
+upgradeable without reinstallation.</p>
+
+<p><strong>Which free software do you use daily?</strong></p>
+
+<p>GNU/Linux with LXDE desktop, bash for interactive dialog and
+programming, texlive for documentation and correspondence,

+
+<p><strong>Which strategy do you believe is the right one to use to
+get schools to use free software?</strong></p>
+
+<p>Strong arguments are</p>
+
+<ul>
+
+ <li>Knowledge is free, and so should be methods and tools for
+ teaching and learning.</li>
+
+ <li>Students can learn with and use the same software at school, at
+ home, and at their working place without running into license or
+ conversion problems.</li>
+
+ <li>Closed source or proprietary software hides knowledge rather
+ than exposing it, and proprietary software vendors try to bind
+ customers to certain products. But teachers need to teach
+ science, not products.</li>
+
+ <li>If you have everything you for daily work as open source, what
+ would you need proprietary software for?</li>
+
+</ul>

- <description><p>The last few days I came across a few good causes that should get
-wider attention. I recommend signing and donating to each one of
-these. :)</p>
-
-<p>Via <a href="http://www.debian.org/News/weekly/2013/18/">Debian
-Project News for 2013-10-14</a> I came across the Outreach Program for
-Women program which is a Google Summer of Code like initiative to get
-more women involved in free software. One debian sponsor has offered
-to match <a href="http://debian.ch/opw2013">any donation done to Debian
-earmarked</a> for this initiative. I donated a few minutes ago, and
-hope you will to. :)</p>
-
-<p>And the Electronic Frontier Foundation just announced plans to
-create <a href="https://supporters.eff.org/donate/nsa-videos">video
-documentaries about the excessive spying</a> on every Internet user that
-take place these days, and their need to fund the work. I've already
-donated. Are you next?</p>
-
-<p>For my Norwegian audience, the organisation Studentenes og
-Akademikernes Internasjonale Hjelpefond is collecting signatures for a
-statement under the heading
-<a href="http://saih.no/Bloggers_United/">Bloggers United for Open
-Access</a> for those of us asking for more focus on open access in the
-Norwegian government. So far 499 signatures. I hope you will sign it
-too.</p>

+ <description><p>If you want the ability to electronically communicate directly with
+your neighbors and friends using a network controlled by your peers in
+stead of centrally controlled by a few corporations, or would like to
+experiment with interesting network technology, the
+<a href="http://www.dugnadsnett.no/">Dugnasnett for alle i Oslo</a>
+might be project for you. 39 mesh nodes are currently being planned,
+in the freshly started initiative from NUUG and Hackeriet to create a
+wireless community network. The work is inspired by
+<a href="http://freifunk.net/">Freifunk</a>,
+<a href="http://www.awmn.net/">Athens Wireless Metropolitan
+Network</a>, <a href="http://en.wikipedia.org/wiki/Roofnet">Roofnet</a>
+and other successful mesh networks around the globe. Two days ago we
+held a workshop to try to get people started on setting up their own
+mesh node, and there we decided to create a new mailing list
+<a href="http://lists.nuug.no/mailman/listinfo/dugnadsnett">dugnadsnett
+(at) nuug.no</a> and IRC channel
+<a href="irc://irc.freenode.net/#dugnadsnett.no">#dugnadsnett.no</a> to

- <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 I 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>
-
-<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>
-
-<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>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>
-
-<p><strong>Update 2013-10-12</strong>: I was just
-<a href="http://lists.alioth.debian.org/pipermail/freedombox-discuss/2013-October/005900.html">told
-by the Serval project developers</a> that they no longer use
-batman-adv (but are compatible with it), but their own crypto based
-mesh system.</p>

+
+<p>Mitt ankerpunkt mot å bytte ut fri programvare som fungerer godt
+med godseid programvare er at en mister kontroll over egen
+infrastruktur, låser seg inn i en løsning det vil bli dyrt å komme ut
+av, uten at en får funksjonalitet en ikke kunne skaffet seg med fri
+programvare, eventuelt videreutviklet med de pengene som brukes på
+overgangen til MS Exchange. Personlig planlegger jeg å fortsette å
+laste ned all eposten min til lokal maskin for indeksering og lesing
+med <a href=="http://notmuchmail.org">notmuch</a>, så jeg håper jeg
+ikke blir veldig skadelidende av overgangen.</p>

- <description><p>The other day I was pleased and surprised to discover that Marcelo
-Salvador had published a
-<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
-advantages I believe is one of the most valuable featuers in Debian
-Edu, its central school server making it possible to run hundreds of
-computers without hard drives by installing one central

+ <description><p>After many years break from the package and a vain hope that
+development would be continued by someone else, I finally pulled my
+acts together this morning and wrapped up a new release of chrpath,
+the command line tool to modify the rpath and runpath of already
+compiled ELF programs. The update was triggered by the persistence of
+Isha Vishnoi at IBM, which needed a new config.guess file to get
+support for the ppc64le architecture (powerpc 64-bit Little Endian) he
+is working on. I checked the
+<a href="http://packages.qa.debian.org/chrpath">Debian</a>,
+<a href="https://launchpad.net/ubuntu/+source/chrpath">Ubuntu</a> and
+<a href="https://admin.fedoraproject.org/pkgdb/acls/name/chrpath">Fedora</a>
+packages for interesting patches (failed to find the source from
+OpenSUSE and Mandriva packages), and found quite a few nice fixes.
+These are the release notes:</p>
+
+<p>New in 0.15 released 2013-11-24:</p>
+
+<ul>
+
+ <li>Updated config.sub and config.guess from the GNU project to work
+ with newer architectures. Thanks to isha vishnoi for the heads
+ up.</li>
+
+ <li>Updated README with current URLs.</li>
+
+ <li>Added byteswap fix found in Ubuntu, credited Jeremy Kerr and
+ Matthias Klose.</li>
+
+ <li>Added missing help for -k|--keepgoing option, using patch by
+ Petr Machata found in Fedora.</li>
+
+ <li>Rewrite removal of RPATH/RUNPATH to make sure the entry in
+ .dynamic is a NULL terminated string. Based on patch found in
+ Fedora credited Axel Thimm and Christian Krause.</li>
+
+</ul>
+

+ <pubDate>Fri, 22 Nov 2013 13:40:00 +0100</pubDate>
+ <description><p>I fjor sommer lagde jeg en
+<a href="http://people.skolelinux.org/pere/blog/SQL_database_med_anbud_publisert_p__Doffin.html">offentlig
+tilgjengelig SQL-database over offentlig anbud</a> basert på skraping
+av HTML-data fra Doffin. Den har stått og gått siden da, og har nå
+ca. 28000 oppføringer. Jeg oppdaget da jeg tittet innom at noen
+oppføringer var ikke blitt med, antagelig på grunn av at de fikk
+tildelt sekvensnummer i Doffin en godt stund før de ble publisert,
+slik at min nettsideskraper som fortsatte skrapingen der den slapp
+sist ikke fikk dem med seg. Jeg har fikset litt slik at skraperen nå
+ser litt tilbake i tid for å se om den har gått glipp av noen
+oppføringer, og har skrapet på nytt fra midten av september 2013 og
+fremover. Det bør dermed bli en mer komplett database for kommende
+måneder. Hvis jeg får tid skal jeg forsøke å skrape "glemte" data fra
+før midten av september 2013, men tør ikke garantere at det blir
+prioritert med det første. </p>
+
+<p>Men målet med denne bloggposten er å vise hvordan denne
+Doffin-databasen kan brukes og integreres med en RSS-leser, slik at en
+kan la datamaskinen holde et øye med Doffin-annonseringer etter
+nøkkelord. En kan lage sitt eget søk ved å besøke
+<ahref="https://classic.scraperwiki.com/docs/api?name=norwegian-doffin#sqlite">API-et
+hos Scraperwiki</a>, velge format rss2 og så legge inn noe ala dette i
+"query in SQL":</p>
+
+<p><pre>
+select title, scrapedurl as link, abstract as description,
+ publishdate as pubDate from 'swdata'
+ where abstract like '%linux%' or title like '%linux%'
+ order by seq desc limit 20
+</pre></p>
+
+<p>Dette vil søke opp alle anbud med ordet linux i oppsummering eller
+tittel. En kan lage mer avanserte søk hvis en ønsker det. URL-en som
+dukker opp nederst på siden kan en så gi til sin RSS-leser (jeg bruker
+akregator selv), og så automatisk få beskjed hvis det dukker opp anbud
+med det aktuelle nøkkelordet i teksten. Merk at kapasiteten og
+ytelsen hos Scraperwiki er begrenset, så ikke be RSS-leseren hente ned
+oftere enn en gang hver dag.</p>
+

+Det er bare å søke på det en er interessert i. Kopier gjerne

+avanserte søk. SQLite-filen med Doffin-oppføringer kan lastes med fra
+Scraperwiki for de som vil grave dypere.</p>
