-&lt;p&gt;Den norske bokbransjen har
-&lt;a href=&quot;http://www.digi.no/823912/nei-til-moms-paa-e-boker&quot;&gt;bedt om at
-digitale bøker må få mva-fritak&lt;/a&gt; slik papirbøker har det, og
-&lt;a href=&quot;http://www.digi.no/836875/moms-paa-alt-digitalt-innhold&quot;&gt;finansdepartementet
-har sagt nei&lt;/a&gt;.  Det er et interessant spørsmål om digitale bøker
-bør ha mva-fritak eller ikke, og svaret er ikke så enkelt som et ja
-eller nei.
-&lt;a href=&quot;http://www.digi.no/836925/norske-e-boker-truet-av-moms&quot;&gt;Enkelte
-medlemmer&lt;/a&gt; av bokbransjen truer med å droppe den planlagte
-lanseringen av norske digitale bøker med digitale restriksjonsmekanismer
-(DRM) som de har snakket om å gjennomføre nå i vår, og det må de
-gjerne gjøre for min del.&lt;/p&gt;
-
-&lt;p&gt;Papirbøker har mva-fritak pga. at de fremmer kultur- og
-kunnskapsspredning.  Digitale bøker uten digitale
-restriksjonsmekanismer (DRM) fremmer kultur- og kunnskapsspredning,
-mens digitale bøker med DRM hindrer kultur og kunnskapsspredning.
-Digitale bøker uten DRM bør få mva-fritak da det er salg av bøker på
-lik linje med salg av papirbøker, mens digitale bøker med DRM ikke bør
-få det da det er utleie av bøker og ikke salg.&lt;/p&gt;
-
-&lt;p&gt;Jeg foretrekker å kjøpe bøker, og velger dermed å la være å bruke
-DRM-belastede digitale bøker.  Vet ikke helt hva jeg ville være villig
-til å betale for å leie en bok, men tror ikke det er mange kronene.
-Heldigvis er det mye bøker tilgjengelig uten slike restriksjoner, og
-de som vil ha tak i engelske bøker kan laste ned bøker som er
-tilgjengelig uten bruksbegresninger fra &lt;a http://www.archive.org/&quot;&gt;The
-Internet Archive&lt;/a&gt;. Der er det pr. i dag 1 889 313 bøker
-tilgjengelig. De er tilgjengelig i flere formater. Besøk
-&lt;a href=&quot;http://www.archive.org/details/texts&quot;&gt;oversikten over tekster
-der&lt;/a&gt; for å se hva de har.
+&lt;p&gt;Det står dårlig til med toget når en finner på å la det
+&lt;a href=&quot;http://www.aftenposten.no/nyheter/iriks/article3677060.ece&quot;&gt;kappkjøre
+med sykkel&lt;/a&gt;...  Jeg tror det trengs strukturendringer for å få
+fikset på togproblemene i Norge.&lt;/p&gt;
+
+&lt;p&gt;Mon tro hva toglinje mellom Narvik og Tromsø ville hatt slags
+effekt på området der?&lt;/p&gt;

                <description>

-&lt;p&gt;On Tuesday, the Debian/Lenny based version of
-&lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt; was finally
-shipped.  This was a major leap forward for the project, and I am very
-pleased that we finally got the release wrapped up.  Work on the first
-point release starts imediately, as we plan to get that one out a
-month after the major release, to include all fixes for bugs we found
-and fixed too late in the release process to include last Tuesday.&lt;/p&gt;
-
-&lt;p&gt;Perhaps it even is time for some partying?&lt;/p&gt;
-
-&lt;p&gt;After this first point release, my plan is to focus again on the
-next major release, based on Squeeze.  We will try to get as many of
-the fixes we need into the official Debian packages before the freeze,
-and have just a few weeks or months to make it happen.&lt;/p&gt;
+&lt;p&gt;It is strange to watch how a bug in Debian causing KDM to fail to
+start at boot when an NVidia video card is used is handled.  The
+problem seem to be that the nvidia X.org driver uses a long time to
+initialize, and this duration is longer than kdm is configured to
+wait.&lt;/p&gt;
+
+&lt;p&gt;I came across two bugs related to this issue,
+&lt;a href=&quot;http://bugs.debian.org/583312&quot;&gt;#583312&lt;/a&gt; initially filed
+against initscripts and passed on to nvidia-glx when it became obvious
+that the nvidia drivers were involved, and
+&lt;a href=&quot;http://bugs.debian.org/524751&quot;&gt;#524751&lt;/a&gt; initially filed against
+kdm and passed on to src:nvidia-graphics-drivers for unknown reasons.&lt;/p&gt;
+
+&lt;p&gt;To me, it seem that no-one is interested in actually solving the
+problem nvidia video card owners experience and make sure the Debian
+distribution work out of the box for these users.  The nvidia driver
+maintainers expect kdm to be set up to wait longer, while kdm expect
+the nvidia driver maintainers to fix the driver to start faster, and
+while they wait for each other I guess the users end up switching to a
+distribution that work for them.  I have no idea what the solution is,
+but I am pretty sure that waiting for each other is not it.&lt;/p&gt;
+
+&lt;p&gt;I wonder why we end up handling bugs this way.&lt;/p&gt;

-&lt;p&gt;Ble nettopp gjort oppmerksom på en
-&lt;a href=&quot;http://www.version2.dk/artikel/13690-breaking-odf-vinder-dokumentformat-krigen &quot;&gt;nyhet fra Version2&lt;/a&gt;
-fra Danmark, der det hevdes at Folketinget har vedtatt at ODF skal
-brukes som dokumentutvekslingsformat i Staten.&lt;/p&gt;
-
-&lt;p&gt;Hyggelig lesning, spesielt hvis det viser seg at de av vedtatt
-kravlisten for hva som skal aksepteres som referert i kommentarfeltet
-til artikkelen og
-&lt;a href=&quot;http://www.version2.dk/artikel/13693-er-ooxml-doemt-ude-her-er-kravene-til-en-offentlig-dokumentstandard&quot;&gt;en
-annen artikkel&lt;/a&gt; i samme nett-avis.  Liker spesielt godt denne:&lt;/p&gt;
-
-&lt;p&gt;&lt;blockquote&gt; Det skal demonstreres, at standarden i sin helhed kan
-implementeres af alle direkte i sin helhed på flere
-platforme.&lt;/blockquote&gt;&lt;/p&gt;
-
-&lt;p&gt;Noe slikt burde være et krav også i Norge.&lt;/p&gt;
+&lt;p&gt;A few days ago, parallel booting was enabled in Debian/testing.
+The feature seem to hold up pretty well, but three fairly serious
+issues are known and should be solved:
+
+&lt;p&gt;&lt;ul&gt;
+
+&lt;li&gt;The wicd package seen to
+&lt;a href=&quot;http://bugs.debian.org/508289&quot;&gt;break NFS mounting&lt;/a&gt; and
+&lt;a href=&quot;http://bugs.debian.org/581586&quot;&gt;network setup&lt;/a&gt; when
+parallel booting is enabled.  No idea why, but the wicd maintainer
+seem to be on the case.&lt;/li&gt;
+
+&lt;li&gt;The nvidia X driver seem to
+&lt;a href=&quot;http://bugs.debian.org/583312&quot;&gt;have a race condition&lt;/a&gt;
+triggered more easily when parallel booting is in effect.  The
+maintainer is on the case.&lt;/li&gt;
+
+&lt;li&gt;The sysv-rc package fail to properly enable dependency based boot
+sequencing (the shutdown is broken) when old file-rc users
+&lt;a href=&quot;http://bugs.debian.org/575080&quot;&gt;try to switch back&lt;/a&gt; to
+sysv-rc.  One way to solve it would be for file-rc to create
+/etc/init.d/.legacy-bootordering, and another is to try to make
+sysv-rc more robust.  Will investigate some more and probably upload a
+workaround in sysv-rc to help those trying to move from file-rc to
+sysv-rc get a working shutdown.&lt;/li&gt;
+
+&lt;/ul&gt;&lt;/p&gt;
+
+&lt;p&gt;All in all not many surprising issues, and all of them seem
+solvable before Squeeze is released.  In addition to these there are
+some packages with bugs in their dependencies and run level settings,
+which I expect will be fixed in a reasonable time span.&lt;/p&gt;
+
+&lt;p&gt;If you report any problems with dependencies in init.d scripts to
+the BTS, please usertag the report to get it to show up at
+&lt;a href=&quot;http://bugs.debian.org/cgi-bin/pkgreport.cgi?users=initscripts-ng-devel@lists.alioth.debian.org&quot;&gt;the
+list of usertagged bugs related to this&lt;/a&gt;.&lt;/p&gt;
+
+&lt;p&gt;Update: Correct bug number to file-rc issue.&lt;/p&gt;

-&lt;p&gt;One of the new features in the next Debian/Lenny based release of
-Debian Edu/Skolelinux, which is scheduled for release in the next few
-days, is automatic configuration of the service monitoring system
-Nagios.  The previous release had automatic configuration of trend
-analysis using Munin, and this Lenny based release take that a step
-further.&lt;/p&gt;
-
-&lt;p&gt;When installing a Debian Edu Main-server, it is automatically
-configured as a Munin and Nagios server.  In addition, it is
-configured to be a server for the
-&lt;a href=&quot;http://wiki.debian.org/DebianEdu/HowTo/SiteSummary&quot;&gt;SiteSummary
-system&lt;/a&gt; I have written for use in Debian Edu.  The SiteSummary
-system is inspired by a system used by the University of Oslo where I
-work.  In short, the system provide a centralised collector of
-information about the computers on the network, and a client on each
-computer submitting information to this collector.  This allow for
-automatic information on which packages are installed on each machine,
-which kernel the machines are using, what kind of configuration the
-packages got etc.  This also allow us to automatically generate Munin
-and Nagios configuration.&lt;/p&gt;
-
-&lt;p&gt;All computers reporting to the sitesummary collector with the
-munin-node package installed is automatically enabled as a Munin
-client and graphs from the statistics collected from that machine show
-up automatically on http://www/munin/ on the Main-server.&lt;/p&gt;
-
-&lt;p&gt;All non-laptop computers reporting to the sitesummary collector are
-automatically monitored for network presence (ping and any network
-services detected).  In addition, all computers (also laptops) with
-the nagios-nrpe-server package installed and configured the way
-sitesummary would configure it, are monitored for full disks, software
-raid status, swap free and other checks that need to run locally on
-the machine.&lt;/p&gt;
-
-&lt;p&gt;The result is that the administrator on a school using Debian Edu
-based on Lenny will be able to check the health of his installation
-with one look at the Nagios settings, without having to spend any time
-keeping the Nagios configuration up-to-date.&lt;/p&gt;
-
-&lt;p&gt;The only configuration one need to do to get Nagios up and running
-is to set the password used to get access via HTTP.  The system
-administrator need to run &quot;&lt;tt&gt;htpasswd /etc/nagios3/htpasswd.users
-nagiosadmin&lt;/tt&gt;&quot; to create a nagiosadmin user and set a password for
-it to be able to log into the Nagios web pages.  After that,
-everything is taken care of.&lt;/p&gt;
+&lt;p&gt;After a long break from debian-installer development, I finally
+found time today to return to the project.  Having to spend less time
+working dependency based boot in debian, as it is almost complete now,
+definitely helped freeing some time.&lt;/p&gt;
+
+&lt;p&gt;A while back, I ran into a problem while working on Debian Edu.  We
+include some firmware packages on the Debian Edu CDs, those needed to
+get disk and network controllers working.  Without having these
+firmware packages available during installation, it is impossible to
+install Debian Edu on the given machine, and because our target group
+are non-technical people, asking them to provide firmware packages on
+an external medium is a support pain.  Initially, I expected it to be
+enough to include the firmware packages on the CD to get
+debian-installer to find and use them.  This proved to be wrong.
+Next, I hoped it was enough to symlink the relevant firmware packages
+to some useful location on the CD (tried /cdrom/ and
+/cdrom/firmware/).  This also proved to not work, and at this point I
+found time to look at the debian-installer code to figure out what was
+going to work.&lt;/p&gt;
+
+&lt;p&gt;The firmware loading code is in the hw-detect package, and a closer
+look revealed that it would only look for firmware packages outside
+the installation media, so the CD was never checked for firmware
+packages.  It would only check USB sticks, floppies and other
+&quot;external&quot; media devices.  Today I changed it to also look in the
+/cdrom/firmware/ directory on the mounted CD or DVD, which should
+solve the problem I ran into with Debian edu.  I also changed it to
+look in /firmware/, to make sure the installer also find firmware
+provided in the initrd when booting the installer via PXE, to allow us
+to provide the same feature in the PXE setup included in Debian
+Edu.&lt;/p&gt;
+
+&lt;p&gt;To make sure firmware deb packages with a license questions are not
+activated without asking if the license is accepted, I extended
+hw-detect to look for preinst scripts in the firmware packages, and
+run these before activating the firmware during installation.  The
+license question is asked using debconf in the preinst, so this should
+solve the issue for the firmware packages I have looked at so far.&lt;/p&gt;
+
+&lt;p&gt;If you want to discuss the details of these features, please
+contact us on debian-boot@lists.debian.org.&lt;/p&gt;

-&lt;p&gt;Via Slashdot fant jeg en
-&lt;a href=&quot;http://www.cnn.com/2009/OPINION/12/29/schneier.air.travel.security.theater/index.html&quot;&gt;nydelig
-kommentar fra Bruce Schneier&lt;/a&gt; som ble publisert hos CNN i går.  Den
-forklarer forbilledlig hvorfor sikkerhetsteater og innføring av
-totalitære politistatmetoder ikke er løsningen for å gjøre verden
-sikrere.  Anbefales på det varmeste.&lt;/p&gt;
-
-&lt;p&gt;Oppdatering: Kom over
-&lt;a href=&quot;http://gizmodo.com/5435675/president-obama-its-time-to-fire-the-tsa&quot;&gt;nok
-en kommentar&lt;/a&gt; om den manglende effekten av dagens sikkerhetsteater
-på flyplassene.&lt;/p&gt;
+&lt;p&gt;For en stund tilbake kjøpte jeg en magnetkortleser for å kunne
+titte på hva som er skrevet inn på magnetstripene til ulike kort.  Har
+ikke hatt tid til å analysere mange kort så langt, men tenkte jeg
+skulle dele innholdet på to kort med mine lesere.&lt;/p&gt;
+
+&lt;p&gt;For noen dager siden tok jeg flyet til Harstad og Hurtigruten til
+Bergen.  Flytoget fra Oslo S til flyplassen ga meg en billett med
+magnetstripe.  Påtrykket finner jeg følgende informasjon:&lt;/p&gt;
+
+&lt;pre&gt;
+Flytoget Airport Express Train
+
+Fra - Til        : Oslo Sentralstasjon
+Kategori         : Voksen
+Pris             : Nok 170,00
+Herav mva. 8,00% : NOK 12,59
+Betaling         : Kontant
+Til - Fra        : Oslo Lufthavn
+Utstedt:         : 08.05.10
+Gyldig Fra-Til   : 08.05.10-07.11.10
+Billetttype      : Enkeltbillett
+
+102-1015-100508-48382-01-08
+&lt;/pre&gt;
+
+&lt;p&gt;På selve magnetstripen er innholdet
+&lt;tt&gt;;E?+900120011=23250996541068112619257138248441708433322932704083389389062603279671261502492655?&lt;/tt&gt;.
+Aner ikke hva innholdet representerer, og det er lite overlapp mellom
+det jeg ser trykket på billetten og det jeg ser av tegn i
+magnetstripen.  Håper det betyr at de bruker kryptografiske metoder
+for å gjøre det vanskelig å forfalske billetter.&lt;/p&gt;
+
+&lt;p&gt;Den andre billetten er fra Hurtigruten, der jeg mistenker at
+strekkoden på fronten er mer brukt enn magnetstripen (det var i hvert
+fall den biten vi stakk inn i dørlåsen).&lt;/p&gt;
+
+&lt;p&gt;Påtrykket forsiden er følgende:&lt;/p&gt;
+
+&lt;pre&gt;

+&lt;p&gt;På selve magnetstripen er innholdet
+&lt;tt&gt;;1316010007421930=00000000000000000000?+E?&lt;/tt&gt;.  Heller ikke her
+ser jeg mye korrespondanse mellom påtrykk og magnetstripe.&lt;/p&gt;

-&lt;p&gt;De færreste er klar over at Skolelinux-prosjektet kom som et resultat
-av en avgjørelse på årsmøtet i
-&lt;a href=&quot;http://www.nuug.no/&quot;&gt;NUUG&lt;/a&gt; i 2000-06-29, der Håkon Wium
-Lie, da varamedlem i styret, tok på seg oppdraget om å starte et
-initiativ kalt &quot;Teach the Teacher&quot;, som skulle være et initiativ for
-å få fri programvare og unix-lignende operativsystemer inn i Skolen.
-Tanken var at en måtte starte med lærerne for at ungene skulle få
-mulighet til å møte en bedre IT-hverdag.  Jeg var tilstede på
-møtet, og hadde sans for ideen, men intet skjedde.  På vårparten
-2001 ble det arrangert en demonstrasjon i anledning at First Tuesday
-hadde invitert Microsoft til et møte for å fortelle om fremtidens
-Internet.  Dette provoserte endel av oss, og EFN og NUUG tok initiativ
-til å arrangere
-&lt;a href=&quot;http://www.digi.no/60982/first-tuesday-mote-med-microsoft-protest&quot;&gt;en
-demonstrasjon utenfor lokalene 2001-05-21&lt;/a&gt;.  Blant de som sto bak
-demonstrasjonen var Vidar Bakke fra NUUG og Håkon W. Lie fra EFN.
-Etter demonstrasjonen arrangerte Håkon en fest hjemme hos seg der alle
-som hadde vært aktive i demonstrasjonsplanlegging og gjennomføringen
-deltok.  Før festen var jeg blitt lei av å vente på at Håkon skulle ta
-initiativ til &quot;Teach the Teacher&quot;, og for å forsøke å få litt fremgang
-besteme jeg meg for å benytte anledningen hos Håkon til å snakke om
-behovet for å hjelpe skolene i gang med bedre datasystemer bestående
-av fri programvare og unix-lignende operativsystemer.  Flere var
-interessert, og Knut Yrvin tenkte på ideen.  Han
-&lt;a href=&quot;http://developer.skolelinux.no/brev/2001-06-28-invitasjon-skolelinux.txt&quot;&gt;ropte
-sammen&lt;/a&gt; til et stiftelsesmøte i prosjektet i sin arbeidsgivers
-Objectwares lokaler ved Ullevål stadion 2001-07-02, og jeg ble med.
-Resten er historie. :)&lt;/p&gt;
+&lt;p&gt;Today, the last piece of the puzzle for roaming laptops in Debian
+Edu finally entered the Debian archive.  Today, the new
+&lt;a href=&quot;http://packages.qa.debian.org/libp/libpam-mklocaluser.html&quot;&gt;libpam-mklocaluser&lt;/a&gt;
+package was accepted.  Two days ago, two other pieces was accepted
+into unstable.  The
+&lt;a href=&quot;http://packages.qa.debian.org/p/pam-python.html&quot;&gt;pam-python&lt;/a&gt;
+package needed by libpam-mklocaluser, and the
+&lt;a href=&quot;http://packages.qa.debian.org/s/sssd.html&quot;&gt;sssd&lt;/a&gt; package
+passed NEW on Monday.  In addition, the
+&lt;a href=&quot;http://packages.qa.debian.org/libp/libpam-ccreds.html&quot;&gt;libpam-ccreds&lt;/a&gt;
+package we need is in experimental (version 10-4) since Saturday, and
+hopefully will be moved to unstable soon.&lt;/p&gt;
+
+&lt;p&gt;This collection of packages allow for two different setups for
+roaming laptops.  The traditional setup would be using libpam-ccreds,
+nscd and libpam-mklocaluser with LDAP or Kerberos authentication,
+which should work out of the box if the configuration changes proposed
+for nscd in &lt;a href=&quot;http://bugs.debian.org/485282&quot;&gt;BTS report
+#485282&lt;/a&gt; is implemented.  The alternative setup is to use sssd with
+libpam-mklocaluser to connect to LDAP or Kerberos and let sssd take
+care of the caching of passwords and group information.&lt;/p&gt;
+
+&lt;p&gt;I have so far been unable to get sssd to work with the LDAP server
+at the University, but suspect the issue is some SSL/GnuTLS related
+problem with the server certificate.  I plan to update the Debian
+package to version 1.2, which is scheduled for next week, and hope to
+find time to make sure the next release will include both the
+Debian/Ubuntu specific patches.  Upstream is friendly and responsive,
+and I am sure we will find a good solution.&lt;/p&gt;
+
+&lt;p&gt;The idea is to set up the roaming laptops to authenticate using
+LDAP or Kerberos and create a local user with home directory in /home/
+when a usre in LDAP logs in via KDM or GDM for the first time, and
+cache the password for offline checking, as well as caching group
+memberhips and other relevant LDAP information.  The
+libpam-mklocaluser package was created to make sure the local home
+directory is in /home/, instead of /site/server/directory/ which would
+be the home directory if pam_mkhomedir was used.  To avoid confusion
+with support requests and configuration, we do not want local laptops
+to have users in a path that is used for the same users home directory
+on the home directory servers.&lt;/p&gt;
+
+&lt;p&gt;One annoying problem with gdm is that it do not show the PAM
+message passed to the user from libpam-mklocaluser when the local user
+is created.  Instead gdm simply reject the login with some generic
+message.  The message is shown in kdm, ssh and login, so I guess it is
+a bug in gdm.  Have not investigated if there is some other message
+type that can be used instead to get gdm to also show the message.&lt;/p&gt;
+
+&lt;p&gt;If you want to help out with implementing this for Debian Edu,
+please contact us on debian-edu@lists.debian.org.&lt;/p&gt;

                <description>

-&lt;p&gt;Endelig har NUUG klart å få kringkastet ut et av sine fordrag på
-TV.  Foredraget om
-&lt;a href=&quot;http://www.nuug.no/aktiviteter/20090512-bifrost/&quot;&gt;utskriftsløsningen
-Biforst&lt;/a&gt; var først ute, pga. at det var det nyeste foredraget som
-var holdt på norsk, og dermed slapp vi å finne ut av hvordan
-teksting av video skulle gjøres.&lt;/p&gt;
-
-&lt;p&gt;NUUG har vært involvert i
-&lt;a href=&quot;http://www.frikanalen.no/&quot;&gt;Frikanalen&lt;/a&gt; en stund nå, for å
-forsøke å få ut budskapet vårt også på TV, og dette første foredraget
-er en sped start på det vi har planlagt.&lt;/p&gt;
-
-&lt;p&gt;NUUGs første foredrag sendes ut via frikanelen på digitalt
-bakkenett, og alle abonnenter av riks-TV skal dermed ha mulighet til å
-ta inn sendingen.  Slå på TVen 5/12 16:05 (for sent), 12/12 14:00,
-19/12 16:00, 24/12 15:37 eller 26/12 16:11 i år, så skal du få se
-meg, Tollef og alle andre de som deltok på møtet på TV.&lt;p&gt;
+&lt;p&gt;Since this evening, parallel booting is the default in
+Debian/unstable for machines using dependency based boot sequencing.
+Apparently the testing of concurrent booting has been wider than
+expected, if I am to believe the
+&lt;a href=&quot;http://lists.debian.org/debian-devel/2010/05/msg00122.html&quot;&gt;input
+on debian-devel@&lt;/a&gt;, and I concluded a few days ago to move forward
+with the feature this weekend, to give us some time to detect any
+remaining problems before Squeeze is frozen.  If serious problems are
+detected, it is simple to change the default back to sequential boot.
+The upload of the new sysvinit package also activate a new upstream
+version.&lt;/p&gt;
+
+More information about
+&lt;a href=&quot;http://wiki.debian.org/LSBInitScripts/DependencyBasedBoot&quot;&gt;dependency
+based boot sequencing&lt;/a&gt; is available from the Debian wiki.  It is
+currently possible to disable parallel booting when one run into
+problems caused by it, by adding this line to /etc/default/rcS:&lt;/p&gt;
+
+&lt;blockquote&gt;&lt;pre&gt;
+CONCURRENCY=none
+&lt;/pre&gt;&lt;/blockquote&gt;
+
+&lt;p&gt;If you report any problems with dependencies in init.d scripts to
+the BTS, please usertag the report to get it to show up at
+&lt;a href=&quot;http://bugs.debian.org/cgi-bin/pkgreport.cgi?users=initscripts-ng-devel@lists.alioth.debian.org&quot;&gt;the
+list of usertagged bugs related to this&lt;/a&gt;.&lt;/p&gt;

-&lt;p&gt;Dagens
-&lt;a href=&quot;http://www.statkart.no/Gratis+karttjenester.d25-SwJfY1-.ips&quot;&gt;kartnyhet&lt;/a&gt;
-er at kartverket gir ikke-kommersiell tilgang til
-en WMS-tjeneste der en til privat bruk kan hente ut bilder av
-kartutsnitt så lenge disse ikke lagres lokalt, brukes i begrenset
-oppløsning og ikke skader kartverket og rettighetshavernes omdømme og
-interesse.&lt;/p&gt;
-
-&lt;p&gt;I går publiserte Ivan Sanchez
-&lt;a href=&quot;http://www.opengeodata.org/2009/11/11/921/&quot;&gt;kaketesten&lt;/a&gt;
-som et forslag til en (av forhåpentligvis flere) måter å teste om kart
-eller kartdata er fritt tilgjengelige på.  Testen er enkel, og sier
-enkelt (oversatt av meg): Et sett med geodata, eller en kart, er kun
-fritt tilgjengelig hvis noen kan gi deg en kake med det kartet på
-toppen, som en gave.  Kartverkets publisering av kart feiler så vidt
-jeg kan se denne testen fullstendig.  En kan slik jeg leser vilkårene
-ikke be en konditor om å lage en kake (brudd på kravet om
-ikke-kommersiell bruk) med kartverkets kart.&lt;/p&gt;
-
-&lt;p&gt;De som vil lage karttjenester basert på denne nye tjenesten fra
-kartverket vil gjøre det på kartverkets nåde og med sterke bindinger
-og begresninger.  Det blir dermed helt uinteressant for meg.  Jeg vil
-nok fortsette å bruke data fra
-&lt;a href=&quot;http://www.openstreetmap.org&quot;&gt;OpenStreetmap.org&lt;/a&gt;, der jeg
-har kontrollen med tilgang til kartdataene, og kan endre på de
-underliggende dataene som jeg ønsker.&lt;/p&gt;
-
-&lt;p&gt;Som et eksempel, så trenger vi til en norsk
-&lt;a href=&quot;http://www.fixmystreet.com/&quot;&gt;FixMyStreet-installasjon&lt;/a&gt;
-tilgang til vektorutgaven av kommunegrensene.  Denne nye karttjenesten
-er ubrukelig til dette.&lt;/p&gt;
+&lt;p&gt;In the recent Debian Edu versions, the
+&lt;a href=&quot;http://wiki.debian.org/DebianEdu/HowTo/SiteSummary&quot;&gt;sitesummary
+system&lt;/a&gt; is used to keep track of the machines in the school
+network.  Each machine will automatically report its status to the
+central server after boot and once per night.  The network setup is
+also reported, and using this information it is possible to get the
+MAC address of all network interfaces in the machines.  This is useful
+to update the DHCP configuration.&lt;/p&gt;
+
+&lt;p&gt;To give some idea how to use sitesummary, here is a one-liner to
+ist all MAC addresses of all machines reporting to sitesummary.  Run
+this on the collector host:&lt;/p&gt;
+
+&lt;blockquote&gt;&lt;pre&gt;
+perl -MSiteSummary -e &#39;for_all_hosts(sub { print join(&quot; &quot;, get_macaddresses(shift)), &quot;\n&quot;; });&#39;
+&lt;/pre&gt;&lt;/blockquote&gt;
+
+&lt;p&gt;This will list all MAC addresses assosiated with all machine, one
+line per machine and with space between the MAC addresses.&lt;/p&gt;
+
+&lt;p&gt;To allow system administrators easier job at adding static DHCP
+addresses for hosts, it would be possible to extend this to fetch
+machine information from sitesummary and update the DHCP and DNS
+tables in LDAP using this information.  Such tool is unfortunately not
+written yet.&lt;/p&gt;

-&lt;p&gt;Det er svært gledelig å se at
-&lt;a href=&quot;http://www.aftenposten.no/nyheter/iriks/article3360796.ece&quot;&gt;retten
-fant at Telenor ikke skal fungere som Internet-voktere&lt;/a&gt; på vegne av
-opphavsrettsmafiaen.  TONO påstår ikke overraskende &quot;rettighetshaverne
-er rettsløse&quot;.  De burde jo vite alt om hvordan rettighetshaverne blir
-behandlet, som har
-&lt;a href=&quot;http://www.ballade.no/nmi.nsf/doc/art2009042008430427192492&quot;&gt;nektet
-å hjelpe et av sine medlemmer i en plagiatsak&lt;/a&gt; mot Universal i
-Polen.&lt;/p&gt;
-
-&lt;p&gt;Ved opphavsrettsbrudd så er det jo den som offentliggjort
-kulturuttrykk ulovlig som må stilles til ansvar, og ikke noen andre.
-Hverken Telenor eller Pirate Bay publiserer innholdet.  Telenor lager
-en Internet-tjeneste som brukes av borgerne til sitt daglige virke,
-det være seg å holde kontakt med barnebarn, skaffe medisinsk viten
-eller holde seg orientert i samfunnsdebatten.  Det bør de gjøre uten å
-tvinges til å være overvåkningsinstans.  Og Pirate Bay lager en
-katalog over hvor lovlig og ulovlig innhold på Internet er å få tak i.
-De publiserer ikke innholdet, de lager kun en katalog over det.  Hvis
-en ikke liker det som blir publisert, så må det tas opp med den som
-publiserer, ikke noen andre.&lt;/p&gt;
-
-&lt;p&gt;Personlig velger jeg å stort sett bruke kulturuttrykk som
-publiseres med mer brukervennlige vilkår, som CC-BY og lignende.&lt;/p&gt;
+&lt;p&gt;The last few days a new boot system called
+&lt;a href=&quot;http://www.freedesktop.org/wiki/Software/systemd&quot;&gt;systemd&lt;/a&gt;
+has been
+&lt;a href=&quot;http://0pointer.de/blog/projects/systemd.html&quot;&gt;introduced&lt;/a&gt;
+
+to the free software world.  I have not yet had time to play around
+with it, but it seem to be a very interesting alternative to
+&lt;a href=&quot;http://upstart.ubuntu.com/&quot;&gt;upstart&lt;/a&gt;, and might prove to be
+a good alternative for Debian when we are able to switch to an event
+based boot system.  Tollef is
+&lt;a href=&quot;http://bugs.debian.org/580814&quot;&gt;in the process&lt;/a&gt; of getting
+systemd into Debian, and I look forward to seeing how well it work.  I
+like the fact that systemd handles init.d scripts with dependency
+information natively, allowing them to run in parallel where upstart
+at the moment do not.&lt;/p&gt;
+
+&lt;p&gt;Unfortunately do systemd have the same problem as upstart regarding
+platform support.  It only work on recent Linux kernels, and also need
+some new kernel features enabled to function properly.  This means
+kFreeBSD and Hurd ports of Debian will need a port or a different boot
+system.  Not sure how that will be handled if systemd proves to be the
+way forward.&lt;/p&gt;
+
+&lt;p&gt;In the mean time, based on the
+&lt;a href=&quot;http://lists.debian.org/debian-devel/2010/05/msg00122.html&quot;&gt;input
+on debian-devel@&lt;/a&gt; regarding parallel booting in Debian, I have
+decided to enable full parallel booting as the default in Debian as
+soon as possible (probably this weekend or early next week), to see if
+there are any remaining serious bugs in the init.d dependencies.  A
+new version of the sysvinit package implementing this change is
+already in experimental.  If all go well, Squeeze will be released
+with parallel booting enabled by default.&lt;/p&gt;

                <description>

-&lt;p&gt;Under helgens utviklersamling i
-&lt;a href=&quot;http://www.skolelinux.no/&quot;&gt;Skolelinux&lt;/a&gt; fikk jeg endelig
-satt meg ned sammen med Ronny Aasen i styret for å få et webbasert
-medlemsregister tilbake på plass for foreningen som passer på
-skolelinuxprosjektet.  Etter flere års knot og problemer, er nå
-memberdb satt opp og klart til bruk.  Import av det gamle
-medlemsregisteret har vist seg vanskelig, så alle medlemmer bes om å
-registrere seg på nytt.  Hvis du støtter FRiSKs formål så er du
-hjertelig velkommen til
-&lt;a href=&quot;http://medlem.friprogramvareiskolen.no/&quot;&gt;å melde deg
-inn&lt;/a&gt;. Formålet lyder:&lt;/p&gt;
-
-&lt;blockquote&gt;Linux i skolen skal tilrettelegge for og informere om bruk
-av fri programvare, i henhold til Debian Free Software Guidelines av
-2002-02-03, i den norske skolen, slik som f.eks. Linux og
-GNU.&lt;/blockquote&gt;
+&lt;p&gt;These days, the init.d script dependencies in Squeeze are quite
+complete, so complete that it is actually possible to run all the
+init.d scripts in parallell based on these dependencies.  If you want
+to test your Squeeze system, make sure
+&lt;a href=&quot;http://wiki.debian.org/LSBInitScripts/DependencyBasedBoot&quot;&gt;dependency
+based boot sequencing&lt;/a&gt; is enabled, and add this line to
+/etc/default/rcS:&lt;/p&gt;
+
+&lt;blockquote&gt;&lt;pre&gt;
+CONCURRENCY=makefile
+&lt;/pre&gt;&lt;/blockquote&gt;
+
+&lt;p&gt;That is it.  It will cause sysv-rc to use the startpar tool to run
+scripts in parallel using the dependency information stored in
+/etc/init.d/.depend.boot, /etc/init.d/.depend.start and
+/etc/init.d/.depend.stop to order the scripts.  Startpar is configured
+to try to start the kdm and gdm scripts as early as possible, and will
+start the facilities required by kdm or gdm as early as possible to
+make this happen.&lt;/p&gt;
+
+&lt;p&gt;Give it a try, and see if you like the result.  If some services
+fail to start properly, it is most likely because they have incomplete
+init.d script dependencies in their startup script (or some of their
+dependent scripts have incomplete dependencies).  Report bugs and get
+the package maintainers to fix it. :)&lt;/p&gt;
+
+&lt;p&gt;Running scripts in parallel could be the default in Debian when we
+manage to get the init.d script dependencies complete and correct.  I
+expect we will get there in Squeeze+1, if we get manage to test and
+fix the remaining issues.&lt;/p&gt;
+
+&lt;p&gt;If you report any problems with dependencies in init.d scripts to
+the BTS, please usertag the report to get it to show up at
+&lt;a href=&quot;http://bugs.debian.org/cgi-bin/pkgreport.cgi?users=initscripts-ng-devel@lists.alioth.debian.org&quot;&gt;the
+list of usertagged bugs related to this&lt;/a&gt;.&lt;/p&gt;
