-<p>If Debian is to migrate to upstart on Linux, I expect some init.d
-scripts to migrate (some of) their operations to upstart job while
-keeping the init.d for hurd and kfreebsd.  The packages with such
-needs will need a way to get their init.d scripts to behave
-differently when used with sysvinit and with upstart.  Because of
-this, I had a look at the environment variables set when a init.d
-script is running under upstart, and when it is not.</p>
-
-<p>With upstart, I notice these environment variables are set when a
-script is started from rcS.d/ (ignoring some irrelevant ones like
-COLUMNS):</p>
-
-<blockquote><pre>
-DEFAULT_RUNLEVEL=2
-previous=N
-PREVLEVEL=
-RUNLEVEL=
-runlevel=S
-UPSTART_EVENTS=startup
-UPSTART_INSTANCE=
-UPSTART_JOB=rc-sysinit
-</pre></blockquote>
-
-<p>With sysvinit, these environment variables are set for the same
-script.</p>
-
-<blockquote><pre>
-INIT_VERSION=sysvinit-2.88
-previous=N
-PREVLEVEL=N
-RUNLEVEL=S
-runlevel=S
-</pre></blockquote>
-
-<p>The RUNLEVEL and PREVLEVEL environment variables passed on from
-sysvinit is not set by upstart.  Not sure if it is intentional or not
-to not be compatible with sysvinit in this regard.</p>
-
-<p>For scripts needing to behave differently when upstart is used,
-looking for the UPSTART_JOB environment variable seem to be a good
-choice.</p>
+<p>For ca. et og et halvt år siden
+<a href="http://people.skolelinux.org/pere/blog/Kart_over_overv__kningskamera_i_Norge.html">startet
+jeg på et kart over overvåkningskamera i Norge</a>, i regi av
+<a href="http://www.personvern.no/">personvernforeningen</a>.  Det har
+blitt oppdatert regelmessing, og jeg oppdaterte det nettopp.  Fra den
+spede start med 22 kamera registrert er det nå registrert 54 kamera.
+Det er bare en brøkdel av de kamera som finnes i Norge, men det går
+sakte men sikkert i riktig retning.</p>
+
+<p>Informasjonen registreres fortsatt direkte inn i
+<a href="http://www.openstreetmap.org/">OpenStreetmap</a>, og hentes
+automatisk over i
+<a href="http://people.skolelinux.no/pere/surveillance-norway/"spesialkartet</a>

+OSM-dumpen for Norge.</p>

-<p>Via the
-<a href="http://feedproxy.google.com/~r/robweir/antic-atom/~3/QzU4RgoAGMg/weekly-links-10.html">blog
-of Rob Weir</a> I came across the very interesting essay named

+hvor hver og en av oss beveger oss</a> pågår, og en ting som har
+kommet lite frem i debatten er at det faktisk er en menneskerett å
+kunne ferdes anonymt internt i ens eget land.</p>
+
+<p>Fant en grei kilde for dette i et
+<a href="http://www.datatilsynet.no/upload/Microsoft%20Word%20-%2009-01399-2%20H+%C2%A9ringsnotat%20-%20Samferdselsdepartementet%20-%20Utkas%C3%94%C3%87%C2%AA.pdf">skriv
+fra Datatilsynet</a> til Samferdselsdepartementet om tema:</p>
+
+<blockquote><p>Retten til å ferdes anonymt kan utledes av
+menneskerettskonvensjonen artikkel 8 og av EUs personverndirektiv.
+Her heter det at enkeltpersoners grunnleggende rettigheter og frihet
+må respekteres, særlig retten til privatlivets fred.  I både
+personverndirektivet og i den norske personopplysningsloven er
+selvråderetten til hver enkelt et av grunnprinsippene, hovedsaklig
+uttrykt ved at en må gi et frivillig, informert og uttrykkelig
+samtykke til behandling av personopplysninger.</p></blockquote>
+
+<p>For meg er det viktig at jeg kan ferdes anonymt, og det er litt av
+bakgrunnen til at jeg handler med kontanter, ikke har mobiltelefon og
+forventer å kunne reise med bil og kollektivtrafikk uten at det blir
+registrert hvor jeg har vært.  Ruter angriper min rett til å ferdes
+uten radiopeiler med sin innføring av RFID-kort, og dokumenterer sitt
+ønske om å registrere hvor kundene befant seg ved å ønske å gebyrlegge
+oss som ikke registrerer oss hver gang vi beveger oss med
+kollektivtrafikken i Oslo.  Jeg synes det er hårreisende.</p>

-<p>When using sitesummary at a site to track machines, it is possible

-information extracted from each machine.  The script to do so is
-included in the sitesummary package, and here is example output from
-the Skolelinux build servers:</p>
-
-<blockquote><pre>
-maintainer:~# /usr/lib/sitesummary/hardware-model-summary

-  [no-dmi-info]                 3
-maintainer:~#
-</pre></blockquote>
-
-<p>The quality of the report depend on the quality of the DMI tables
-provided in each machine.  Here there are Intel machines without model
-information listed with Intel as vendor and mo model, and virtual Xen
-machines listed as [no-dmi-info].  One can add -l as a command line
-option to list the individual machines.</p>
-
-<p>A larger list is
-<a href="http://narvikskolen.no/sitesummary/">available from the the
-city of Narvik</a>, which uses Skolelinux on all their shools and also
-provide the basic sitesummary report publicly.  In their report there
-are ~1400 machines. I know they use both Ubuntu and Skolelinux on
-their machines, and as sitesummary is available in both distributions,
-it is trivial to get all of them to report to the same central
-collector.</p>
+<p>A few days ago I had the mixed pleasure of bying a new digital
+camera, a Canon IXUS 130.  It was instructive and very disturbing to
+be able to verify that also this camera producer have the nerve to
+specify how I can or can not use the videos produced with the camera.
+Even thought I was aware of the issue, the options with new cameras
+are limited and I ended up bying the camera anyway.  What is the
+problem, you might ask?  It is software patents, MPEG-4, H.264 and the
+MPEG-LA that is the problem, and our right to record our experiences
+without asking for permissions that is at risk.
+
+<p>On page 27 of the Danish instruction manual, this section is
+written:</p>
+
+<blockquote>
+<p>This product is licensed under AT&T patents for the MPEG-4 standard
+and may be used for encoding MPEG-4 compliant video and/or decoding
+MPEG-4 compliant video that was encoded only (1) for a personal and
+non-commercial purpose or (2) by a video provider licensed under the
+AT&T patents to provide MPEG-4 compliant video.</p>
+
+<p>No license is granted or implied for any other use for MPEG-4
+standard.</p>
+</blockquote>
+
+<p>In short, the camera producer have chosen to use technology
+(MPEG-4/H.264) that is only provided if I used it for personal and
+non-commercial purposes, or ask for permission from the organisations
+holding the knowledge monopoly (patent) for technology used.</p>
+
+<p>This issue has been brewing for a while, and I recommend you to
+read
+"<a href="http://www.osnews.com/story/23236/Why_Our_Civilization_s_Video_Art_and_Culture_is_Threatened_by_the_MPEG-LA">Why

+<a href="http://www.digistan.org/open-standard:definition">free and

+kan en altså ha korreksjonene på plass i sin Garmin-GPS i løpet av en

+Jobbene som tegner kartene, henter ut kartdumpene og konverterer til

-<p>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.</p>
-
-<p>I came across two bugs related to this issue,
-<a href="http://bugs.debian.org/583312">#583312</a> initially filed
-against initscripts and passed on to nvidia-glx when it became obvious
-that the nvidia drivers were involved, and
-<a href="http://bugs.debian.org/524751">#524751</a> initially filed against
-kdm and passed on to src:nvidia-graphics-drivers for unknown reasons.</p>
-
-<p>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.</p>
-
-<p>I wonder why we end up handling bugs this way.</p>
+<p>In the <a href="http://popcon.debian.org/unknown/by_vote">Debian
+popularity-contest numbers</a>, the adobe-flashplugin package the
+second most popular used package that is missing in Debian.  The sixth
+most popular is flashplayer-mozilla.  This is a clear indication that
+working flash is important for Debian users.  Around 10 percent of the
+users submitting data to popcon.debian.org have this package
+installed.</p>
+
+<p>In the report written by Lars Risan in August 2008
+(«<a href="http://wiki.skolelinux.no/Dokumentasjon/Rapporter?action=AttachFile&do=view&target=Skolelinux_i_bruk_rapport_1.0.pdf">Skolelinux
+i bruk – Rapport for Hurum kommune, Universitetet i Agder og
+stiftelsen SLX Debian Labs</a>»), one of the most important problems
+schools experienced with <a href="http://www.skolelinux.org/">Debian
+Edu/Skolelinux</a> was the lack of working Flash.  A lot of educational
+web sites require Flash to work, and lacking working Flash support in
+the web browser and the problems with installing it was perceived as a
+good reason to stay with Windows.</p>
+
+<p>I once saw a funny and sad comment in a web forum, where Linux was
+said to be the retarded cousin that did not really understand
+everything you told him but could work fairly well.  This was a
+comment regarding the problems Linux have with proprietary formats and
+non-standard web pages, and is sad because it exposes a fairly common
+understanding of whose fault it is if web pages that only work in for
+example Internet Explorer 6 fail to work on Firefox, and funny because
+it explain very well how annoying it is for users when Linux
+distributions do not work with the documents they receive or the web
+pages they want to visit.</p>
+
+<p>This is part of the reason why I believe it is important for Debian
+and Debian Edu to have a well working Flash implementation in the
+distribution, to get at least popular sites as Youtube and Google
+Video to working out of the box.  For Squeeze, Debian have the chance
+to include the latest version of Gnash that will make this happen, as
+the new release 0.8.8 was published a few weeks ago and is resting in
+unstable.  The new version work with more sites that version 0.8.7.
+The Gnash maintainers have asked for a freeze exception, but the
+release team have not had time to reply to it yet.  I hope they agree
+with me that Flash is important for the Debian desktop users, and thus
+accept the new package into Squeeze.</p>

-<p>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:
-
-<p><ul>
-
-<li>The wicd package seen to
-<a href="http://bugs.debian.org/508289">break NFS mounting</a> and
-<a href="http://bugs.debian.org/581586">network setup</a> when
-parallel booting is enabled.  No idea why, but the wicd maintainer
-seem to be on the case.</li>
-
-<li>The nvidia X driver seem to
-<a href="http://bugs.debian.org/583312">have a race condition</a>
-triggered more easily when parallel booting is in effect.  The
-maintainer is on the case.</li>
-
-<li>The sysv-rc package fail to properly enable dependency based boot
-sequencing (the shutdown is broken) when old file-rc users
-<a href="http://bugs.debian.org/575080">try to switch back</a> 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.</li>
-
-</ul></p>
-
-<p>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.</p>
-

-<p>Update: Correct bug number to file-rc issue.</p>
+<p>This evening I made my first Perl GUI application.  The last few
+days I have worked on a Perl module for controlling my recently
+aquired Spykee robots, and the module is now getting complete enought
+that it is possible to use it to control the robot driving at least.
+It was now time to figure out how to use it to create some GUI to
+allow me to drive the robot around.  I picked PerlQt as I have had
+positive experiences with the Qt API before, and spent a few minutes
+browsing the web for examples.  Using Qt Designer seemed like a short
+cut, so I ended up writing the perl GUI using Qt Designer and
+compiling it into a perl program using the puic program from
+libqt-perl.  Nothing fancy yet, but it got buttons to connect and
+drive around.</p>
+
+<p>The perl module I have written provide a object oriented API for
+controlling the robot.  Here is an small example on how to use it:</p>
+
+<p><pre>
+use Spykee;
+Spykee::discover(sub {$robot{$_[0]} = $_[1]});
+my $host = (keys %robot)[0];
+my $spykee = Spykee->new();
+$spykee->contact($host, "admin", "admin");
+$spykee->left();
+sleep 2;
+$spykee->right();
+sleep 2;
+$spykee->forward();
+sleep 2;
+$spykee->back();
+sleep 2;
+$spykee->stop();
+</pre></p>
+
+<p>Thanks to the release of the source of the robot firmware, I could
+peek into the implementation at the other end to figure out how to
+implement the protocol used by the robot.  I've implemented several of
+the commands the robot understand, but is still missing the camera
+support to make it possible to control the robot from remote.  First I
+want to implement support for uploading new firmware and configuring
+the wireless network, to make it possible to bootstrap a Spykee robot
+without the producers Windows and MacOSX software (I only have Linux,
+so I had to ask a friend to come over to get the robot testing
+going. :).</p>
+
+<p>Will release the source to the public soon, but need to figure out
+where to make it available first.  I will add a link to 
+<a href="http://wiki.nuug.no/grupper/robot/">the NUUG wiki</a> for
+those that want to check back later to find it.</p>

-<p>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.</p>
-
-<p>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.</p>
-
-<p>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
-"external" 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.</p>
-
-<p>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.</p>
-
-<p>If you want to discuss the details of these features, please
-contact us on debian-boot@lists.debian.org.</p>
+<p>Ble tipset i dag om at et forslag om å stoppe forsøkene med
+elektronisk stemmegiving utenfor valglokaler er
+<a href="http://www.stortinget.no/no/Saker-og-publikasjoner/Saker/Sak/?p=46616">til
+behandling</a> i Stortinget.
+<a href="http://www.stortinget.no/Global/pdf/Representantforslag/2009-2010/dok8-200910-128.pdf">Forslaget</a>

+
+<p>Håper det får flertall.</p>

-<p>For en stund tilbake kjøpte jeg en magnetkortleser for å kunne

-ikke hatt tid til å analysere mange kort så langt, men tenkte jeg
-skulle dele innholdet på to kort med mine lesere.</p>

+fail to handle hard links properly.  A simple way to spot this is to
+look at the . and .. entries in the directory tree.  These should have
+a link count >1, but on sshfs the count is 1.  I just tested to see
+what happen when trying to hardlink, and this fail as well:</p>

-<p>Today, the last piece of the puzzle for roaming laptops in Debian
-Edu finally entered the Debian archive.  Today, the new
-<a href="http://packages.qa.debian.org/libp/libpam-mklocaluser.html">libpam-mklocaluser</a>
-package was accepted.  Two days ago, two other pieces was accepted
-into unstable.  The
-<a href="http://packages.qa.debian.org/p/pam-python.html">pam-python</a>
-package needed by libpam-mklocaluser, and the
-<a href="http://packages.qa.debian.org/s/sssd.html">sssd</a> package
-passed NEW on Monday.  In addition, the
-<a href="http://packages.qa.debian.org/libp/libpam-ccreds.html">libpam-ccreds</a>
-package we need is in experimental (version 10-4) since Saturday, and
-hopefully will be moved to unstable soon.</p>
-
-<p>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 <a href="http://bugs.debian.org/485282">BTS report
-#485282</a> 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.</p>
-
-<p>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.</p>
-
-<p>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.</p>
-
-<p>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.</p>
-
-<p>If you want to help out with implementing this for Debian Edu,
-please contact us on debian-edu@lists.debian.org.</p>
+<p>Jeg skrev for et halvt år siden hvordan
+<a href="http://people.skolelinux.org/pere/blog/Sikkerhet__teater__og_hvordan_gj__re_verden_sikrere.html">samfunnet
+kaster bort ressurser på sikkerhetstiltak som ikke fungerer</a>.  Kom
+nettopp over en
+<a href="http://www.askthepilot.com/essays-and-stories/terrorism-tweezers-and-terminal-madness-an-essay-on-security/">historie
+fra en pilot fra USA</a> som kommenterer det samme.  Jeg mistenker det
+kun er uvitenhet og autoritetstro som gjør at så få protesterer.  Har
+veldig sans for piloten omtalt i <a
+href="http://www.aftenposten.no/nyheter/iriks/article2057501.ece">Aftenposten</a> 2007-10-23,
+og skulle ønske flere rettet oppmerksomhet mot problemet.  Det gir
+ikke meg trygghetsfølelse på flyplassene når jeg ser at
+flyplassadministrasjonen kaster bort folk, penger og tid på tull i
+stedet for ting som bidrar til reell økning av sikkerheten.  Det
+forteller meg jo at vurderingsevnen til de som burde bidra til økt
+sikkerhet er svært sviktende, noe som ikke taler godt for de andre
+tiltakene.</p>
+
+<p>Mon tro hva som skjer hvis det fantes en enkel brosjyre å skrive ut
+fra Internet som forklarte hva som er galt med sikkerhetsopplegget på
+flyplassene, og folk skrev ut og la en bunke på flyplassene når de
+passerte.  Kanskje det ville fått flere til å få øynene opp for
+problemet.</p>
+
+<p>Personlig synes jeg flyopplevelsen er blitt så avskyelig at jeg
+forsøker å klare meg med tog, bil og båt for å slippe ubehaget.  Det
+er dog noe vanskelig i det langstrakte Norge og for å kunne besøke de
+delene av verden jeg ønsker å nå.  Mistenker at flere har det slik, og
+at dette går ut over inntjeningen til flyselskapene.  Det er antagelig
+en god ting sett fra et miljøperspektiv, men det er en annen sak.</p>

+<p>Denne høsten skal endelig alle Osloskolene få mulighet til å bruke
+<a href="http://www.skolelinux.org/">Skolelinux</a>.  Ny IT-løsning
+har vært rullet ut i noen måneder nå, og så vidt jeg fikk vite før
+sommeren skulle alle skoler ha nytt opplegg på plass før oppstart nå i
+høst.  På alle skolene skal en kunne velge ved installasjon om en skal
+ha Windows eller Skolelinux på maskinene, og en kan i tillegg
+PXE-boote maskinene over nett som tynne klienter eller diskløse
+arbeidsstasjoner. Jeg er spent på hvor mange skoler som velger å ta i
+bruk Skolelinux, og gleder meg til å se hvordan dette utvikler seg.
+Løsningen leveres av
+<a href="http://www.logica.no/">Logica</a> med
+<a href="http://www.slxdrift.no/">Skolelinux Drift AS</a> som
+underleverandør, og jeg har vært involvert i utviklingen av løsningen

+fantastisk at Skolelinux er kommet så langt siden vi startet i 2001 at
+alle elevene i Osloskolene nå skal få mulighet til å bruke
+løsningen.  Jeg håper de vil sette pris på alle de
