-&lt;p&gt;One interesting feature in Active Directory, is the ability to
-create a new user with an expired password, and thus force the user to
-change the password on the first login attempt.&lt;/p&gt;
-
-&lt;p&gt;I&#39;m not quite sure how to do that with the LDAP setup in Debian
-Edu, but did some initial testing with a local account.  The account
-and password aging information is available in /etc/shadow, but
-unfortunately, it is not possible to specify an expiration time for
-passwords, only a maximum age for passwords.&lt;/p&gt;
-
-&lt;p&gt;A freshly created account (using adduser test) will have these
-settings in /etc/shadow:&lt;/p&gt;
-
-&lt;blockquote&gt;&lt;pre&gt;
-root@tjener:~# chage -l test
-Last password change                                    : May 02, 2010
-Password expires                                        : never
-Password inactive                                       : never
-Account expires                                         : never
-Minimum number of days between password change          : 0
-Maximum number of days between password change          : 99999
-Number of days of warning before password expires       : 7
-root@tjener:~#
-&lt;/pre&gt;&lt;/blockquote&gt;
-
-&lt;p&gt;The only way I could come up with to create a user with an expired
-account, is to change the date of the last password change to the
-lowest value possible (January 1th 1970), and the maximum password age
-to the difference in days between that date and today.  To make it
-simple, I went for 30 years (30 * 365 = 10950) and January 2th (to
-avoid testing if 0 is a valid value).&lt;/p&gt;
-
-&lt;p&gt;After using these commands to set it up, it seem to work as
-intended:&lt;/p&gt;
-
-&lt;blockquote&gt;&lt;pre&gt;
-root@tjener:~# chage -d 1 test; chage -M 10950 test
-root@tjener:~# chage -l test
-Last password change                                    : Jan 02, 1970
-Password expires                                        : never
-Password inactive                                       : never
-Account expires                                         : never
-Minimum number of days between password change          : 0
-Maximum number of days between password change          : 10950
-Number of days of warning before password expires       : 7
-root@tjener:~#  
-&lt;/pre&gt;&lt;/blockquote&gt;
-
-&lt;p&gt;So far I have tested this with ssh and console, and kdm (in
-Squeeze) login, and all ask for a new password before login in the
-user (with ssh, I was thrown out and had to log in again).&lt;/p&gt;
-
-&lt;p&gt;Perhaps we should set up something similar for Debian Edu, to make
-sure only the user itself have the account password?&lt;/p&gt;
-
-&lt;p&gt;If you want to comment on or help out with implementing this for
-Debian Edu, please contact us on debian-edu@lists.debian.org.&lt;/p&gt;
+&lt;p&gt;For ca. et og et halvt år siden
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Kart_over_overv__kningskamera_i_Norge.html&quot;&gt;startet
+jeg på et kart over overvåkningskamera i Norge&lt;/a&gt;, i regi av
+&lt;a href=&quot;http://www.personvern.no/&quot;&gt;personvernforeningen&lt;/a&gt;.  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.&lt;/p&gt;
+
+&lt;p&gt;Informasjonen registreres fortsatt direkte inn i
+&lt;a href=&quot;http://www.openstreetmap.org/&quot;&gt;OpenStreetmap&lt;/a&gt;, og hentes
+automatisk over i
+&lt;a href=&quot;http://people.skolelinux.no/pere/surveillance-norway/&quot;spesialkartet&lt;/a&gt;
+når jeg kjører et script for å filtrere ut overvåkningskamera fra
+OSM-dumpen for Norge.&lt;/p&gt;

 		<description>
-&lt;p&gt;For some years now, I have wondered how we should handle laptops in
-Debian Edu.  The Debian Edu infrastructure is mostly designed to
-handle stationary computers, and less suited for computers that come
-and go.&lt;/p&gt;
-
-&lt;p&gt;Now I finally believe I have an sensible idea on how to adjust
-Debian Edu for laptops, by introducing a new profile for them, for
-example called Roaming Workstations.  Here are my thought on this.
-The setup would consist of the following:&lt;/p&gt;
-
-&lt;ul&gt;
-
- &lt;li&gt;During installation, the user name of the owner / primary user of
-   the laptop is requested and a local home directory is set up for
-   the user, with uid and gid information fetched from the LDAP
-   server.  This allow the user to work also when offline.  The
-   central home directory can be available in a subdirectory on
-   request, for example mounted via CIFS.  It could be mounted
-   automatically when a user log in while on the Debian Edu network,
-   and unmounted when the machine is taken away (network down,
-   hibernate, etc), it can be set up to do automatic mounting on
-   request (using autofs), or perhaps some GUI button on the desktop
-   can be used to access it when needed.  Perhaps it is enough to use
-   the fish protocol in KDE?&lt;/li&gt;
-
- &lt;li&gt;Password checking is set up to use LDAP or Kerberos
-   authentication when the machine is on the Debian Edu network, and
-   to cache the password for offline checking when the machine unable
-   to reach the LDAP or Kerberos server.  This can be done using
-   &lt;a href=&quot;http://www.padl.com/OSS/pam_ccreds.html&quot;&gt;libpam-ccreds&lt;/a&gt;
-   or the Fedora developed
-   &lt;a href=&quot;https://fedoraproject.org/wiki/Features/SSSD&quot;&gt;System
-   Security Services Daemon&lt;/a&gt; packages.&lt;/li&gt;
-
- &lt;li&gt;File synchronisation with the central home directory is set up
-   using a shared directory in both the local and the central home
-   directory, using unison.&lt;/li&gt;
-
- &lt;li&gt;Printing should be set up to print to all printers broadcasting
-   their existence on the local network, and should then work out of
-   the box with CUPS.  For sites needing accurate printer quotas, some
-   system with Kerberos authentication or printing via ssh could be
-   implemented.&lt;/li&gt;
-
- &lt;li&gt;For users that should have local root access to their laptop,
-   sudo should be used to allow this to the local user.&lt;/li&gt;
-
- &lt;li&gt;It would be nice if user and group information from LDAP is
-   cached on the client, but given that there are entries for the
-   local user and primary group in /etc/, it should not be needed.&lt;/li&gt;
-
-&lt;/ul&gt;
-
-&lt;p&gt;I believe all the pieces to implement this are in Debian/testing at
-the moment.  If we work quickly, we should be able to get this ready
-in time for the Squeeze release to freeze.  Some of the pieces need
-tweaking, like libpam-ccreds should get support for pam-auth-update
-(&lt;a href=&quot;http://bugs.debian.org/566718&quot;&gt;#566718&lt;/a&gt;) and nslcd (or
-perhaps debian-edu-config) should get some integration code to stop
-its daemon when the LDAP server is unavailable to avoid long timeouts
-when disconnected from the net.  If we get Kerberos enabled, we need
-to make sure we avoid long timeouts there too.&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;
+&lt;p&gt;Debatten rundt sporveiselskapet i Oslos (Ruter AS) ønske om
+&lt;a href=&quot;http://www.aftenposten.no/nyheter/iriks/article3808135.ece&quot;&gt;Ã¥
+radiomerke med RFID&lt;/a&gt; alle sine kunder og
+&lt;a href=&quot;http://www.aftenposten.no/nyheter/article3809746.ece&quot;&gt;registerere
+hvor hver og en av oss beveger oss&lt;/a&gt; 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.&lt;/p&gt;
+
+&lt;p&gt;Fant en grei kilde for dette i et
+&lt;a href=&quot;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&quot;&gt;skriv
+fra Datatilsynet&lt;/a&gt; til Samferdselsdepartementet om tema:&lt;/p&gt;
+
+&lt;blockquote&gt;&lt;p&gt;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.&lt;/p&gt;&lt;/blockquote&gt;
+
+&lt;p&gt;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.&lt;/p&gt;

-&lt;p&gt;The last few weeks i have had the pleasure of reading a
-thought-provoking collection of essays by Cory Doctorow, on topics
-touching copyright, virtual worlds, the future of man when the
-conscience mind can be duplicated into a computer and many more. The
-book titled &quot;Content: Selected Essays on Technology, Creativity,
-Copyright, and the Future of the Future&quot; is available with few
-restrictions on the web, for example from
-&lt;a href=&quot;http://craphound.com/content/&quot;&gt;his own site&lt;/a&gt;. I read the
-epub-version from
-&lt;a href=&quot;http://www.feedbooks.com/book/2883&quot;&gt;feedbooks&lt;/a&gt; using
-&lt;a href=&quot;http://www.fbreader.org/&quot;&gt;fbreader&lt;/a&gt; and my N810. I
-strongly recommend this book.&lt;/p&gt;
+&lt;p&gt;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.
+
+&lt;p&gt;On page 27 of the Danish instruction manual, this section is
+written:&lt;/p&gt;
+
+&lt;blockquote&gt;
+&lt;p&gt;This product is licensed under AT&amp;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&amp;T patents to provide MPEG-4 compliant video.&lt;/p&gt;
+
+&lt;p&gt;No license is granted or implied for any other use for MPEG-4
+standard.&lt;/p&gt;
+&lt;/blockquote&gt;
+
+&lt;p&gt;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.&lt;/p&gt;
+
+&lt;p&gt;This issue has been brewing for a while, and I recommend you to
+read
+&quot;&lt;a href=&quot;http://www.osnews.com/story/23236/Why_Our_Civilization_s_Video_Art_and_Culture_is_Threatened_by_the_MPEG-LA&quot;&gt;Why
+Our Civilization&#39;s Video Art and Culture is Threatened by the
+MPEG-LA&lt;/a&gt;&quot; by Eugenia Loli-Queru and
+&quot;&lt;a href=&quot;http://webmink.com/2010/09/03/h-264-and-foss/&quot;&gt;H.264 Is Not
+The Sort Of Free That Matters&lt;/a&gt;&quot; by Simon Phipps to learn more about
+the issue.  The solution is to support the
+&lt;a href=&quot;http://www.digistan.org/open-standard:definition&quot;&gt;free and
+open standards&lt;/a&gt; for video, like &lt;a href=&quot;http://www.theora.org/&quot;&gt;Ogg
+Theora&lt;/a&gt;, and avoid MPEG-4 and H.264 if you can.&lt;/p&gt;

-&lt;p&gt;&lt;a href=&quot;http://www.nuug.no/aktiviteter/20100413-kerberos/&quot;&gt;Yesterdays
-NUUG presentation&lt;/a&gt; about Kerberos was inspiring, and reminded me
-about the need to start using Kerberos in Skolelinux.  Setting up a
-Kerberos server seem to be straight forward, and if we get this in
-place a long time before the Squeeze version of Debian freezes, we
-have a chance to migrate Skolelinux away from NFSv3 for the home
-directories, and over to an architecture where the infrastructure do
-not have to trust IP addresses and machines, and instead can trust
-users and cryptographic keys instead.&lt;/p&gt;
-
-&lt;p&gt;A challenge will be integration and administration.  Is there a
-Kerberos implementation for Debian where one can control the
-administration access in Kerberos using LDAP groups?  With it, the
-school administration will have to maintain access control using flat
-files on the main server, which give a huge potential for errors.&lt;/p&gt;
-
-&lt;p&gt;A related question I would like to know is how well Kerberos and
-pam-ccreds (offline password check) work together.  Anyone know?&lt;/p&gt;
-
-&lt;p&gt;Next step will be to use Kerberos for access control in Lwat and
-Nagios.  I have no idea how much work that will be to implement.  We
-would also need to document how to integrate with Windows AD, as such
-shared network will require two Kerberos realms that need to cooperate
-to work properly.&lt;/p&gt;
-
-&lt;p&gt;I believe a good start would be to start using Kerberos on the
-skolelinux.no machines, and this way get ourselves experience with
-configuration and integration.  A natural starting point would be
-setting up ldap.skolelinux.no as the Kerberos server, and migrate the
-rest of the machines from PAM via LDAP to PAM via Kerberos one at the
-time.&lt;/p&gt;
-
-&lt;p&gt;If you would like to contribute to get this working in Skolelinux,
-I recommend you to see the video recording from yesterdays NUUG
-presentation, and start using Kerberos at home.  The video show show
-up in a few days.&lt;/p&gt;
+&lt;p&gt;Jeg ble riktig fascinert av
+&lt;a href=&quot;http://www.aftenposten.no/nyheter/iriks/article3800967.ece&quot;&gt;en
+artikkel i Aftenposten&lt;/a&gt; om hvor hardt Navteq jobber for å oppdatere
+kartene som brukes i navigasjons-GPSer, der det blant annet heter at
+&quot;på grunn av teknikken tar det alt fra tre til tolv måneder før
+kartene er oppdatert&quot;.  NÃ¥r en kjenner hva slags oppdateringshastighet
+som er tilgjengelig på
+&lt;a href=&quot;http://www.openstreetmap.org/&quot;&gt;OpenStreetmap&lt;/a&gt; som
+oppdateres på dugnad, blir det litt trist å se hva noe av det beste en
+kan kjøpe for penger får til.&lt;/p&gt;
+
+&lt;p&gt;Fra en endrer kartdataene i databasen til OpenStreetmap tar det
+ca. 15 minutter før endringen er synlig på kartet som alle kan se på
+web.  Dernest overføres det daglig til en kartdump som lastes ned av
+personen som lager Garmin-kart for Norge ca. en gang i uken.  Med
+OpenStreetmap.org og &lt;a href=&quot;http://www.frikart.no/&quot;&gt;Frikart.no&lt;/a&gt;
+kan en altså ha korreksjonene på plass i sin Garmin-GPS i løpet av en
+uke.  Det er også av tekniske årsaker at det tar så langt tid.
+Jobbene som tegner kartene, henter ut kartdumpene og konverterer til
+Garmin-format tar minutter og timer å gjennomføre, slik at de ikke
+gjøres kontinuerlig men kun regelmessing.&lt;/p&gt;

-ikke kjennet så mye som et snev av provokasjon fra denne litt morsomme

-Hr. Fossen.  Må innrømme at jeg tviler på det.&lt;/p&gt;
-
-&lt;p&gt;Det hele bringer tankene tilbake til Sture Hansen i Hallo i Uken.&lt;/p&gt;

+users submitting data to popcon.debian.org have this package
+installed.&lt;/p&gt;

+schools experienced with &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian
+Edu/Skolelinux&lt;/a&gt; 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.&lt;/p&gt;
+
+&lt;p&gt;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.&lt;/p&gt;
+
+&lt;p&gt;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.&lt;/p&gt;

-&lt;p&gt;6 years ago, as part of the Debian Edu development I am involved
-in, I asked for a hook in the kdm and gdm setup to run scripts as root
-when the user log out.  A bug was submitted against the xfree86-common
-package in 2004 (&lt;a href=&quot;http://bugs.debian.org/230422&quot;&gt;#230422&lt;/a&gt;),
-and revisited every time Debian Edu was working on a new release.
-Today, this finally paid off.&lt;/p&gt;
-
-&lt;p&gt;The framework for this feature was today commited to the git
-repositry for the xorg package, and the git repository for xdm has
-been updated to use this framework.  Next on my agenda is to make sure
-kdm and gdm also add code to use this framework.&lt;/p&gt;
-
-&lt;p&gt;In Debian Edu, we want to ability to run commands as root when the
-user log out, to get rid of runaway processes and do general cleanup
-after a user.  With this framework in place, we finally can do that in
-a generic way that work with all display managers using this
-framework.  My goal is to get all display managers in Debian use it,
-similar to how they use the Xsession.d framework today.&lt;p&gt;
+&lt;p&gt;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.&lt;/p&gt;
+
+&lt;p&gt;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:&lt;/p&gt;
+
+&lt;p&gt;&lt;pre&gt;
+use Spykee;
+Spykee::discover(sub {$robot{$_[0]} = $_[1]});
+my $host = (keys %robot)[0];
+my $spykee = Spykee-&gt;new();
+$spykee-&gt;contact($host, &quot;admin&quot;, &quot;admin&quot;);
+$spykee-&gt;left();
+sleep 2;
+$spykee-&gt;right();
+sleep 2;
+$spykee-&gt;forward();
+sleep 2;
+$spykee-&gt;back();
+sleep 2;
+$spykee-&gt;stop();
+&lt;/pre&gt;&lt;/p&gt;
+
+&lt;p&gt;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&#39;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. :).&lt;/p&gt;
+
+&lt;p&gt;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 
+&lt;a href=&quot;http://wiki.nuug.no/grupper/robot/&quot;&gt;the NUUG wiki&lt;/a&gt; for
+those that want to check back later to find it.&lt;/p&gt;

-&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 href=&quot;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;Ble tipset i dag om at et forslag om å stoppe forsøkene med
+elektronisk stemmegiving utenfor valglokaler er
+&lt;a href=&quot;http://www.stortinget.no/no/Saker-og-publikasjoner/Saker/Sak/?p=46616&quot;&gt;til
+behandling&lt;/a&gt; i Stortinget.
+&lt;a href=&quot;http://www.stortinget.no/Global/pdf/Representantforslag/2009-2010/dok8-200910-128.pdf&quot;&gt;Forslaget&lt;/a&gt;
+er fremmet av Erna Solberg, Michael Tetzschner og Trond Helleland.&lt;/p&gt;
+
+&lt;p&gt;Håper det får flertall.&lt;/p&gt;

-&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;Just got an email from Tobias Gruetzmacher as a followup on my
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Broken_umask_handling_with_sshfs.html&quot;&gt;previous
+post about sshfs&lt;/a&gt;.  He reported another problem with sshfs.  It
+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 &gt;1, but on sshfs the count is 1.  I just tested to see
+what happen when trying to hardlink, and this fail as well:&lt;/p&gt;
+
+&lt;pre&gt;
+% ln foo bar
+ln: creating hard link `bar&#39; =&gt; `foo&#39;: Function not implemented
+%
+&lt;/pre&gt;
+
+&lt;p&gt;I have not yet found time to implement a test for this in my file
+system test code, but believe having working hard links is useful to
+avoid surprised unix programs.  Not as useful as working file locking
+and symlinks, which are required to get a working desktop, but useful
+nevertheless. :)&lt;/p&gt;
+
+&lt;p&gt;The latest version of the file system test code is available via
+git from
+&lt;a href=&quot;http://github.com/gebi/fs-test&quot;&gt;http://github.com/gebi/fs-test&lt;/a&gt;&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;Jeg skrev for et halvt år siden hvordan
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Sikkerhet__teater__og_hvordan_gj__re_verden_sikrere.html&quot;&gt;samfunnet
+kaster bort ressurser på sikkerhetstiltak som ikke fungerer&lt;/a&gt;.  Kom
+nettopp over en
+&lt;a href=&quot;http://www.askthepilot.com/essays-and-stories/terrorism-tweezers-and-terminal-madness-an-essay-on-security/&quot;&gt;historie
+fra en pilot fra USA&lt;/a&gt; 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 &lt;a
+href=&quot;http://www.aftenposten.no/nyheter/iriks/article2057501.ece&quot;&gt;Aftenposten&lt;/a&gt; 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.&lt;/p&gt;
+
+&lt;p&gt;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.&lt;/p&gt;
+
+&lt;p&gt;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.&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;Denne høsten skal endelig alle Osloskolene få mulighet til å bruke
+&lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt;.  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
+&lt;a href=&quot;http://www.logica.no/&quot;&gt;Logica&lt;/a&gt; med
+&lt;a href=&quot;http://www.slxdrift.no/&quot;&gt;Skolelinux Drift AS&lt;/a&gt; som
+underleverandør, og jeg har vært involvert i utviklingen av løsningen
+via Skolelinux Drift AS siden prosjektet starter.  Jeg synes det er
+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
+&lt;a href=&quot;http://www.skolelinux.no/linux-signpost/&quot;&gt;fantastiske
+brukerprogrammene&lt;/a&gt; som er tilgjengelig i Skolelinux.&lt;/p&gt;
