+ <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>

+urlmap() {

+ curl -s -H 'Accept: application/vnd.vegvesen.nvdb-v1+xml' \
+ "https://www.vegvesen.no/nvdb/api$url" | xmllint --format -
+}
+
+for id in $(seq 1 874) ; do
+ search="{

+ then
+ :
+ else

+done
+
+exit 0

+
+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:

+
+<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>

+ <title>Speeding up the Debian installer using eatmydata and dpkg-divert</title>
+ <link>http://people.skolelinux.org/pere/blog/Speeding_up_the_Debian_installer_using_eatmydata_and_dpkg_divert.html</link>
+ <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Speeding_up_the_Debian_installer_using_eatmydata_and_dpkg_divert.html</guid>
+ <pubDate>Tue, 16 Sep 2014 14:00:00 +0200</pubDate>
+ <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>
+<td>Latitude D505 Main+LTSP LXDE</td>
+<td>64 min (07:46-08:50)</td>
+<td><44 min (11:27-12:11)</td>
+<td>>20 min 18%</td>
+</tr>
+
+<tr>
+<td>Latitude D505 Roaming LXDE</td>
+<td>57 min (08:48-09:45)</td>
+<td>34 min (07:43-08:17)</td>

+</tr>
+
+<tr>
+<td>Latitude D505 Minimal</td>
+<td>22 min (10:37-10:59)</td>

+

+<td>Thinkpad X200 Minimal</td>
+<td>6 min (08:19-08:25)</td>
+<td>4 min (08:04-08:08)</td>
+<td>2 min 33%</td>
+</tr>
+
+<tr>
+<td>Thinkpad X200 Roaming KDE</td>
+<td>19 min (09:21-09:40)</td>
+<td>15 min (10:25-10:40)</td>
+<td>4 min 21%</td>
+</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>
-settrans -fgap /dev/netdde /hurd/netdde
-kill -9 $(ps -ef|awk '/[p]finet/ { print $2}')
-kill -9 $(ps -ef|awk '/[d]evnode/ { print $2}')
-dhclient -v /dev/eth0
+#!/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>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>To clean up, another shell script should go into
+/usr/lib/finish-install.d/ with code like this:
<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
+#! /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>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>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>

+ <description><p>Yesterday, I had the pleasure of attending a talk with the

+<a href="http://www.nuug.no/aktiviteter/20140909-sks-keyservers/">the

+learn that there is a large set of publicly available key servers to

+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

+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>
-cat > /etc/apt/sources.list.d/hurd-ci.list &lt;&lt;EOF
-deb http://darnassus.sceen.net/~teythoon/hurd-ci/ sid main
-EOF
+keyserver pool.sks-keyservers.net
</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>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>
-# aptitude search '?narrow(?version(CURRENT),?origin(Debian Ports))'
-i emacs - GNU Emacs editor (metapackage)
-i gdb - GNU Debugger

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

+ <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>These are the terms for Avid Artist Suite, according to their
+<a href="http://www.avid.com/US/about-avid/legal-notices/legal-enduserlicense2">published
+end user</a>
+<a href="http://www.avid.com/static/resources/common/documents/corporate/LICENSE.pdf">license
+text</a> (converted to lower case text for easier reading):</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>Note the requirement that the videos created can only be used for

+
+<p>The Sorenson Media software have
+<a href="http://www.sorensonmedia.com/terms/">similar terms</a>:</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>

- <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
-mailing list for the chrpath developers</a>, I decided it was time to
-publish a new release. These are the release notes:</p>
-
-<p>New in 0.16 released 2014-01-14:</p>
-
-<ul>
-
- <li>Fixed all minor bugs discovered by Coverity.</li>
- <li>Updated config.sub and config.guess from the GNU project.</li>
- <li>Mention new project mailing list in the documentation.</li>
-
-</ul>
-
-<p>You can
-<a href="https://alioth.debian.org/frs/?group_id=31052">download the
-new version 0.16 from alioth</a>. Please let us know via the Alioth
-project if something is wrong with the new release. The test suite
-did not discover any old errors, so if you find a new one, please also
-include a test suite check.</p>

+ <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>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>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>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>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 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>The independence.</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>
+<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>
-<ul>
+<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>
- <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 ;)
+<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>
-</ul>
+<p><strong>What do you see as the disadvantages of Skolelinux / Debian
+Edu?</strong></p>
-<p>I'm really sorry I cannot say much more about that :(!</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>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>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>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 ;).
-
--->
+<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>

- <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

-#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,
-occasionally LibreOffice for document format conversion. Various
-programming languages for teaching.</p>
-
-<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 <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>
+

+debian-edu-doc package</a>,

+ <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/KOID20005814/et-moete-med-edward-snowden">intervjuet
+med Edward Snowden gjort av den tyske tv-kanalen ARD</a>. Anbefaler

+<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

+ <description><p>Dear lazyweb. I'm planning to set up a small Raspberry Pi computer
+in my car, connected to

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

-hadet det vært veldig fint om du kan send et leserbrev til
-<a href="http://www.uniforum.uio.no/">Uniforum</a> og fortelle om hvor
-greit det er å bruke Exchange i kryss-platform-miljøer? De jeg har
-snakket med sier en greit får lest e-posten sin hvis Exchange har
-slått på IMAP-funksjonalitet, men at kalender og møtebooking ikke
-fungerer godt for Linux-klienter. Jeg har ingen personlig erfaring å
-komme med, så jeg er nysgjerrig på hva andre kan dele av erfaringer
-med universitetet.</p>
-
-<p>Mitt ankerpunkt mot å bytte ut fri programvare som fungerer godt
-med godseid programvare er at en mister kontroll over egen
-infrastruktur, låser seg inn i en løsning det vil bli dyrt å komme ut
-av, uten at en får funksjonalitet en ikke kunne skaffet seg med fri
-programvare, eventuelt videreutviklet med de pengene som brukes på
-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>

- <title>New chrpath release 0.15</title>
- <link>http://people.skolelinux.org/pere/blog/New_chrpath_release_0_15.html</link>
- <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/New_chrpath_release_0_15.html</guid>
- <pubDate>Sun, 24 Nov 2013 09:30:00 +0100</pubDate>
- <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>
-
-<p>You can
-<a href="https://alioth.debian.org/frs/?group_id=31052">download the
-new version 0.15 from alioth</a>. Please let us know via the Alioth
-project if something is wrong with the new release. The test suite
-did not discover any old errors, so if you find a new one, please also
-include a testsuite check.</p>

- <title>RSS-kilde for fritekstsøk i offentlige anbud hos Doffin</title>
- <link>http://people.skolelinux.org/pere/blog/RSS_kilde_for_friteksts_k_i_offentlige_anbud_hos_Doffin.html</link>
- <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/RSS_kilde_for_friteksts_k_i_offentlige_anbud_hos_Doffin.html</guid>
- <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>
-
-<p>Du lurer kanskje på hva slags informasjon en kan få ut fra denne
-databasen. Her er to RSS-kilder, med søkeordet
-"<a href="https://api.scraperwiki.com/api/1.0/datastore/sqlite?format=rss2&name=norwegian-doffin&query=select%20title%2C%20scrapedurl%20as%20link%2C%20abstract%20as%20description%2C%0A%20%20%20%20%20%20%20publishdate%20as%20pubDate%20from%20'swdata'%0A%20%20%20where%20abstract%20like%20'%25linux%25'%20or%20title%20like%20'%25linux%25'%0A%20%20%20order%20by%20seq%20desc%20limit%2020">linux</a>",
