-&lt;p&gt;De siste dagene har Aftenposten
-&lt;a href=&quot;http://www.aftenposten.no/nyheter/iriks/article3718597.ece&quot;&gt;fortalt&lt;/a&gt;
-&lt;a href=&quot;http://www.aftenposten.no/nyheter/iriks/article3724249.ece&quot;&gt;hvordan&lt;/a&gt;
-politet har brukt skriveverktøy som ikke håndterer arabisk tekst og
-tekst som skal skrives fra høyre mot venstre når de har laget
-løpeseddel for å be om informasjon fra publikum.  Resultatet har vært
-en uleselig arabisk-bit på løpeseddelen.  Feilen har oppstått når
-teksten har blitt &quot;kopiert inn i programvare som ikke har støtte for
-språk som skrives fra høyre mot venstre&quot;, og jeg er ganske sikker på
-at det er snakk om Microsoft Office i dette tilfellet.  Er det slik at
-MS Office i Norsk språkdrakt ikke har støtte for tekst som skal
-skrives fra høyre mot venstre?  Jeg tror alle utgaver av
-OpenOffice.org har slik støtte, og det er jo ikke veldig vanskelig å
-la slik støtte finnes i alle utgaver av et program hvis støtten først
-er utviklet.  Aftenpostens melding får meg til å undre om problemet
-ville vært unngått hvis politiet brukte OpenOffice.org i stedet for MS
-Office.&lt;/p&gt;
-
-&lt;p&gt;Mon tro om det er flere eksempler på at MS Office har ødelagt for
-offentlig myndighet?&lt;/p&gt;
+&lt;p&gt;In the &lt;a href=&quot;http://popcon.debian.org/unknown/by_vote&quot;&gt;Debian
+popularity-contest numbers&lt;/a&gt;, 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.&lt;/p&gt;
+
+&lt;p&gt;In the report written by Lars Risan in August 2008
+(«&lt;a href=&quot;http://wiki.skolelinux.no/Dokumentasjon/Rapporter?action=AttachFile&amp;do=view&amp;target=Skolelinux_i_bruk_rapport_1.0.pdf&quot;&gt;Skolelinux
+i bruk – Rapport for Hurum kommune, Universitetet i Agder og
+stiftelsen SLX Debian Labs&lt;/a&gt;»), one of the most important problems
+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;Here is a short update on my &lt;a
-href=&quot;http://people.skolelinux.org/~pere/debian-upgrade-testing/&quot;&gt;my
-Debian Lenny-&gt;Squeeze upgrade testing&lt;/a&gt;.  Here is a summary of the
-difference for Gnome when it is upgraded by apt-get and aptitude.  I&#39;m
-not reporting the status for KDE, because the upgrade crashes when
-aptitude try because of missing conflicts
-(&lt;a href=&quot;http://bugs.debian.org/584861&quot;&gt;#584861&lt;/a&gt; and
-&lt;a href=&quot;http://bugs.debian.org/585716&quot;&gt;#585716&lt;/a&gt;).&lt;/p&gt;
-
-&lt;p&gt;At the end of the upgrade test script, dpkg -l is executed to get a
-complete list of the installed packages.  Based on this I see these
-differences when I did a test run today.  As usual, I do not really
-know what the correct set of packages would be, but thought it best to
-publish the difference.&lt;/p&gt;

-in git&lt;/a&gt; today to try to get apt-get to not remove xorg completely.
-No idea when it hits Squeeze, but when it does I hope it will reduce
-the difference somewhat.
+&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;

                <description>

-&lt;p&gt;For a laptop, centralized user directories and password checking is
-a bit troubling.  Laptops are typically used also when not connected
-to the network, and it is vital for a user to be able to log in or
-unlock the screen saver also when a central server is unavailable.
-This is possible by caching passwords and directory information (user
-and group attributes) locally, and the packages to do so are available
-in Debian.  Here follow two recipes to set this up in Debian/Squeeze.
-It is also possible to set up in Debian/Lenny, but require more manual
-setup there because pam-auth-update is missing in Lenny.&lt;/p&gt;
-
-&lt;h2&gt;LDAP/Kerberos + nscd + libpam-ccreds + libpam-mklocaluser/pam_mkhomedir&lt;/h2&gt;
-
-This is the traditional method with a twist.  The password caching is
-provided by libpam-ccreds (version 10-4 or later is needed on
-Squeeze), and the directory caching is done by nscd.  The directory
-lookup and password checking is done using LDAP.  If one want to use
-Kerberos for password checking the libpam-ldapd package can be
-replaced with libpam-krb5 or libpam-heimdal.  If one is happy having a
-local home directory with the path listed in LDAP, one can use the
-pam_mkhomedir module from pam-modules to make this happen instead of
-using libpam-mklocaluser.  A setup for pam-auth-update to enable
-pam_mkhomedir will have to be written until a fix for
-&lt;a href=&quot;http://bugs.debian.org/568577&quot;&gt;bug #568577&lt;/a&gt; is in the
-archive.  Because I believe it is a bad idea to have local home
-directories using misleading paths like /site/server/partition/, I
-prefer to create a local user with the home directory in /home/.  This
-is done using the libpam-mklocaluser package.&lt;/p&gt;
-
-&lt;p&gt;These packages need to be installed and configured&lt;/p&gt;
-
-&lt;blockquote&gt;&lt;pre&gt;
-libnss-ldapd libpam-ldapd nscd libpam-ccreds libpam-mklocaluser
-&lt;/pre&gt;&lt;/blockquote&gt;
-
-&lt;p&gt;The ldapd packages will ask for LDAP connection information, and
-one have to fill in the values that fits ones own site.  Make sure the
-PAM part uses encrypted connections, to make sure the password is not
-sent in clear text to the LDAP server.  I&#39;ve been unable to get TLS
-certificate checking for a self signed certificate working, which make
-LDAP authentication unsafe for Debian Edu (nslcd is not checking if it
-is talking to the correct LDAP server), and very much welcome feedback
-on how to get this working.&lt;/p&gt;
-
-&lt;p&gt;Because nscd do not have a default configuration fit for offline
-caching until &lt;a href=&quot;http://bugs.debian.org/485282&quot;&gt;bug #485282&lt;/a&gt;
-is fixed, this configuration should be used instead of the one
-currently in /etc/nscd.conf.  The changes are in the fields
-reload-count and positive-time-to-live, and is based on the
-instructions I found in the
-&lt;a href=&quot;http://www.flyn.org/laptopldap/&quot;&gt;LDAP for Mobile Laptops&lt;/a&gt;
-instructions by Flyn Computing.&lt;/p&gt;

-&lt;/pre&gt;&lt;/blockquote&gt;
-
-&lt;p&gt;While we wait for a mechanism to update /etc/nsswitch.conf
-automatically like the one provided in
-&lt;a href=&quot;http://bugs.debian.org/496915&quot;&gt;bug #496915&lt;/a&gt;, the file
-content need to be manually replaced to ensure LDAP is used as the
-directory service on the machine.  /etc/nsswitch.conf should normally
-look like this:&lt;/p&gt;
-
-&lt;blockquote&gt;&lt;pre&gt;
-passwd:         files ldap
-group:          files ldap
-shadow:         files ldap
-hosts:          files mdns4_minimal [NOTFOUND=return] dns mdns4
-networks:       files
-protocols:      files
-services:       files
-ethers:         files
-rpc:            files
-netgroup:       files ldap
-&lt;/pre&gt;&lt;/blockquote&gt;
-
-&lt;p&gt;The important parts are that ldap is listed last for passwd, group,
-shadow and netgroup.&lt;/p&gt;
-
-&lt;p&gt;With these changes in place, any user in LDAP will be able to log
-in locally on the machine using for example kdm, get a local home
-directory created and have the password as well as user and group
-attributes cached.
-
-&lt;h2&gt;LDAP/Kerberos + nss-updatedb + libpam-ccreds +
-  libpam-mklocaluser/pam_mkhomedir&lt;/h2&gt;
-
-&lt;p&gt;Because nscd have had its share of problems, and seem to have
-problems doing proper caching, I&#39;ve seen suggestions and recipes to
-use nss-updatedb to copy parts of the LDAP database locally when the
-LDAP database is available.  I have not tested such setup, because I
-discovered sssd.&lt;/p&gt;
-
-&lt;h2&gt;LDAP/Kerberos + sssd + libpam-mklocaluser&lt;/h2&gt;
-
-&lt;p&gt;A more flexible and robust setup than the nscd combination
-mentioned earlier that has shown up recently, is the
-&lt;a href=&quot;https://fedorahosted.org/sssd/&quot;&gt;sssd&lt;/a&gt; package from Redhat.
-It is part of the &lt;a href=&quot;http://www.freeipa.org/&quot;&gt;FreeIPA&lt;/A&gt; project
-to provide a Active Directory like directory service for Linux
-machines.  The sssd system combines the caching of passwords and user
-information into one package, and remove the need for nscd and
-libpam-ccreds.  It support LDAP and Kerberos, but not NIS.  Version
-1.2 do not support netgroups, but it is said that it will support this
-in version 1.5 expected to show up later in 2010.  Because the
-&lt;a href=&quot;http://packages.qa.debian.org/s/sssd.html&quot;&gt;sssd package&lt;/a&gt;
-was missing in Debian, I ended up co-maintaining it with Werner, and
-version 1.2 is now in testing.
-
-&lt;p&gt;These packages need to be installed and configured to get the
-roaming setup I want&lt;/p&gt;
-
-&lt;blockquote&gt;&lt;pre&gt;
-libpam-sss libnss-sss libpam-mklocaluser
-&lt;/pre&gt;&lt;/blockquote&gt;
-
-The complete setup of sssd is done by editing/creating
-&lt;tt&gt;/etc/sssd/sssd.conf&lt;/tt&gt;.
-
-&lt;blockquote&gt;&lt;pre&gt;
-[sssd]
-config_file_version = 2
-reconnection_retries = 3
-sbus_timeout = 30
-services = nss, pam
-domains = INTERN
-
-[nss]
-filter_groups = root
-filter_users = root
-reconnection_retries = 3
-
-[pam]
-reconnection_retries = 3
-
-[domain/INTERN]
-enumerate = false
-cache_credentials = true
-
-id_provider = ldap
-auth_provider = ldap
-chpass_provider = ldap
-
-ldap_uri = ldap://ldap
-ldap_search_base = dc=skole,dc=skolelinux,dc=no
-ldap_tls_reqcert = never
-ldap_tls_cacert = /etc/ssl/certs/ca-certificates.crt
-&lt;/pre&gt;&lt;/blockquote&gt;
-
-&lt;p&gt;I got the same problem here with certificate checking.  Had to set
-&quot;ldap_tls_reqcert = never&quot; to get it working.&lt;/p&gt;
-
-&lt;p&gt;With the libnss-sss package in testing at the moment, the
-nsswitch.conf file is update automatically, so there is no need to
-modify it manually.&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;The last few days I have been looking into the status of the LDAP
-directory in Debian Edu, and in the process I started to miss a GUI
-tool to browse the LDAP tree.  The only one I was able to find in
-Debian/Squeeze and Lenny is
-&lt;a href=&quot;http://luma.sourceforge.net/&quot;&gt;LUMA&lt;/a&gt;, which has proved to
-be a great tool to get a overview of the current LDAP directory
-populated by default in Skolelinux.  Thanks to it, I have been able to
-find empty and obsolete subtrees, misplaced objects and duplicate
-objects.  It will be installed by default in Debian/Squeeze.  If you
-are working with LDAP, give it a go. :)&lt;/p&gt;
-
-&lt;p&gt;I did notice one problem with it I have not had time to report to
-the BTS yet.  There is no .desktop file in the package, so the tool do
-not show up in the Gnome and KDE menus, but only deep down in in the
-Debian submenu in KDE.  I hope that can be fixed before Squeeze is
-released.&lt;/p&gt;
-
-&lt;p&gt;I have not yet been able to get it to modify the tree yet.  I would
-like to move objects and remove subtrees directly in the GUI, but have
-not found a way to do that with LUMA yet.  So in the mean time, I use
-&lt;a href=&quot;http://www.lichteblau.com/ldapvi/&quot;&gt;ldapvi&lt;/a&gt; for that.&lt;/p&gt;
-
-&lt;p&gt;If you have tips on other GUI tools for LDAP that might be useful
-in Debian Edu, please contact us on debian-edu@lists.debian.org.&lt;/p&gt;
-
-&lt;p&gt;Update 2010-06-29: Ross Reedstrom tipped us about the
-&lt;a href=&quot;http://packages.qa.debian.org/g/gq.html&quot;&gt;gq&lt;/a&gt; package as a
-useful GUI alternative.  It seem like a good tool, but is unmaintained
-in Debian and got a RC bug keeping it out of Squeeze.  Unless that
-changes, it will not be an option for Debian Edu based on Squeeze.&lt;/p&gt;

-&lt;p&gt;A while back, I
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Time_for_new__LDAP_schemas_replacing_RFC_2307_.html&quot;&gt;complained
-about the fact&lt;/a&gt; that it is not possible with the provided schemas
-for storing DNS and DHCP information in LDAP to combine the two sets
-of information into one LDAP object representing a computer.&lt;/p&gt;
-
-&lt;p&gt;In the mean time, I discovered that a simple fix would be to make
-the dhcpHost object class auxiliary, to allow it to be combined with
-the dNSDomain object class, and thus forming one object for one
-computer when storing both DHCP and DNS information in LDAP.&lt;/p&gt;
-
-&lt;p&gt;If I understand this correctly, it is not safe to do this change
-without also changing the assigned number for the object class, and I
-do not know enough about LDAP schema design to do that properly for
-Debian Edu.&lt;/p&gt;
-
-&lt;p&gt;Anyway, for future reference, this is how I believe we could change
-the
-&lt;a href=&quot;http://tools.ietf.org/html/draft-ietf-dhc-ldap-schema-00&quot;&gt;DHCP
-schema&lt;/a&gt; to solve at least part of the problem with the LDAP schemas
-available today from IETF.&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;
 
 &lt;pre&gt;

---- dhcp.schema    (revision 65192)
-+++ dhcp.schema    (working copy)
-@@ -376,7 +376,7 @@

+ln: creating hard link `bar&#39; =&gt; `foo&#39;: Function not implemented
+%

 &lt;/pre&gt;
 
 &lt;/pre&gt;
 

-&lt;p&gt;I very much welcome clues on how to do this properly for Debian
-Edu/Squeeze.  We provide the DHCP schema in our debian-edu-config
-package, and should thus be free to rewrite it as we see fit.&lt;/p&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;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;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;

                <description>

-&lt;p&gt;A few times I have had the need to simulate the way tasksel
-installs packages during the normal debian-installer run.  Until now,
-I have ended up letting tasksel do the work, with the annoying problem
-of not getting any feedback at all when something fails (like a
-conffile question from dpkg or a download that fails), using code like
-this:
-
-&lt;blockquote&gt;&lt;pre&gt;
-export DEBIAN_FRONTEND=noninteractive
-tasksel --new-install
-&lt;/pre&gt;&lt;/blockquote&gt;
-
-This would invoke tasksel, let its automatic task selection pick the
-tasks to install, and continue to install the requested tasks without
-any output what so ever.
-
-Recently I revisited this problem while working on the automatic
-package upgrade testing, because tasksel would some times hang without
-any useful feedback, and I want to see what is going on when it
-happen.  Then it occured to me, I can parse the output from tasksel
-when asked to run in test mode, and use that aptitude command line
-printed by tasksel then to simulate the tasksel run.  I ended up using
-code like this:
-
-&lt;blockquote&gt;&lt;pre&gt;
-export DEBIAN_FRONTEND=noninteractive
-cmd=&quot;$(in_target tasksel -t --new-install | sed &#39;s/debconf-apt-progress -- //&#39;)&quot;
-$cmd
-&lt;/pre&gt;&lt;/blockquote&gt;
-
-&lt;p&gt;The content of $cmd is typically something like &quot;&lt;tt&gt;aptitude -q
---without-recommends -o APT::Install-Recommends=no -y install
-~t^desktop$ ~t^gnome-desktop$ ~t^laptop$ ~pstandard ~prequired
-~pimportant&lt;/tt&gt;&quot;, which will install the gnome desktop task, the
-laptop task and all packages with priority standard , required and
-important, just like tasksel would have done it during
-installation.&lt;/p&gt;
-
-&lt;p&gt;A better approach is probably to extend tasksel to be able to
-install packages without using debconf-apt-progress, for use cases
-like this.&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;&lt;a href=&quot;http://www.dagbladet.no/2010/06/16/nyheter/innenriks/streik/arbeidsliv/12157858/&quot;&gt;Dagbladet
-melder&lt;/a&gt; at Vinmonopolet med bakgrunn i vekterstreiken som pågår i
-Norge for tiden, har bestemt seg for med vitende og vilje å bryte
-sentralbanklovens paragraf 14 ved å nekte folk å betale med
-kontanter, og at flere butikker planlegger å følge deres eksempel.
-Jeg synes det er hårreisende hvis de slipper unna med et slikt
-soleklart lovbrudd, og lurer på hva slags muligheter jeg vil ha hvis
-jeg blir nektet å handle med kontanter.  Jeg handler i hovedsak med
-kontanter selv, da jeg anser det som en borgerrett å kunne handle
-anonymt uten at det blir registrert.  For meg er det et angrep på mitt
-personvern å nekte å ta imot kontant betaling.&lt;/p&gt;
-
-&lt;p&gt;&lt;a href=&quot;http://www.lovdata.no/all/tl-19850524-028-003.html#14&quot;&gt;Paragrafen
-i sentralbankloven&lt;/a&gt; lyder:&lt;/p&gt;
-
-&lt;blockquote&gt;
-&lt;p&gt;§ 14. Tvungent betalingsmiddel&lt;/p&gt;
-
-&lt;p&gt;Bankens sedler og mynter er tvungent betalingsmiddel i Norge. Ingen
-er pliktig til i én betaling å ta imot mer enn femogtyve mynter av
-hver enhet.&lt;/p&gt;
-
-&lt;p&gt;Sterkt skadde sedler og mynter er ikke tvungent
-betalingsmiddel. Banken gir nærmere forskrifter om erstatning for
-bortkomne, brente eller skadde sedler og mynter.&lt;/p&gt;
-
-&lt;p&gt;Selv om en avtale inneholder klausul om betaling av en
-pengeforpliktelse i gullverdi, kan skyldneren frigjøre seg med tvungne
-betalingsmidler uten hensyn til denne klausul.&lt;/p&gt;
-&lt;/blockquote&gt;
-
-&lt;p&gt;Det er med bakgrunn i denne lovet ikke tillatt å nekte å ta imot
-kontakt betaling.  Det er en lov jeg har sans for, og som jeg mener må
-håndheves strengt.&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;

                <description>

-&lt;p&gt;For those of us caring about document exchange and
-interoperability, &lt;a href=&quot;http://www.officeshots.org/&quot;&gt;OfficeShots&lt;/a&gt;
-is a great service.  It is to ODF documents what
-&lt;a href=&quot;http://browsershots.org/&quot;&gt;BrowserShots&lt;/a&gt; is for web
-pages.&lt;/p&gt;
-
-&lt;p&gt;A while back, I was contacted by Knut Yrvin at the part of Nokia
-that used to be Trolltech, who wanted to help the OfficeShots project
-and wondered if the University of Oslo where I work would be
-interested in supporting the project.  I helped him to navigate his
-request to the right people at work, and his request was answered with
-a spot in the machine room with power and network connected, and Knut
-arranged funding for a machine to fill the spot.  The machine is
-administrated by the OfficeShots people, so I do not have daily
-contact with its progress, and thus from time to time check back to
-see how the project is doing.&lt;/p&gt;
-
-&lt;p&gt;Today I had a look, and was happy to see that the Dell box in our
-machine room now is the host for several virtual machines running as
-OfficeShots factories, and the project is able to render ODF documents
-in 17 different document processing implementation on Linux and
-Windows.  This is great.&lt;/p&gt;
+&lt;p&gt;My file system sematics program
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Testing_if_a_file_system_can_be_used_for_home_directories___.html&quot;&gt;presented
+a few days ago&lt;/a&gt; is very useful to verify that a file system can
+work as a unix home directory,and today I had to extend it a bit.  I&#39;m
+looking into alternatives for home directory access here at the
+University of Oslo, and one of the options is sshfs.  My friend
+Finn-Arne mentioned a while back that they had used sshfs with Debian
+Edu, but stopped because of problems.  I asked today what the problems
+where, and he mentioned that sshfs failed to handle umask properly.
+Trying to detect the problem I wrote this addition to my fs testing
+script:&lt;/p&gt;
+
+&lt;pre&gt;
+mode_t touch_get_mode(const char *name, mode_t mode) {
+  mode_t retval = 0;
+  int fd = open(name, O_RDWR|O_CREAT|O_LARGEFILE, mode);
+  if (-1 != fd) {
+    unlink(name);
+    struct stat statbuf;
+    if (-1 != fstat(fd, &amp;statbuf)) {
+      retval = statbuf.st_mode &amp; 0x1ff;
+    }
+    close(fd);
+  }
+  return retval;
+}
+
+/* Try to detect problem discovered using sshfs */
+int test_umask(void) {
+  printf(&quot;info: testing umask effect on file creation\n&quot;);
+
+  mode_t orig_umask = umask(000);
+  mode_t newmode;
+  if (0666 != (newmode = touch_get_mode(&quot;foobar&quot;, 0666))) {
+    printf(&quot;  error: Wrong file mode %o when creating using mode 666 and umask 000\n&quot;,
+           newmode);
+  }
+  umask(007);
+  if (0660 != (newmode = touch_get_mode(&quot;foobar&quot;, 0666))) {
+    printf(&quot;  error: Wrong file mode %o when creating using mode 666 and umask 007\n&quot;,
+           newmode);
+  }
+
+  umask (orig_umask);
+  return 0;
+}
+
+int main(int argc, char **argv) {
+  [...]
+  test_umask();
+  return 0;
+}
+&lt;/pre&gt;
+
+&lt;p&gt;Sure enough.  On NFS to a netapp, I get this result:&lt;/p&gt;
+
+&lt;pre&gt;
+Testing POSIX/Unix sematics on file system
+info: testing symlink creation
+info: testing subdirectory creation
+info: testing fcntl locking
+  Read-locking 1 byte from 1073741824
+  Read-locking 510 byte from 1073741826
+  Unlocking 1 byte from 1073741824
+  Write-locking 1 byte from 1073741824
+  Write-locking 510 byte from 1073741826
+  Unlocking 2 byte from 1073741824
+info: testing umask effect on file creation
+&lt;/pre&gt;
+
+&lt;p&gt;When mounting the same directory using sshfs, I get this
+result:&lt;/p&gt;
+
+&lt;pre&gt;
+Testing POSIX/Unix sematics on file system
+info: testing symlink creation
+info: testing subdirectory creation
+info: testing fcntl locking
+  Read-locking 1 byte from 1073741824
+  Read-locking 510 byte from 1073741826
+  Unlocking 1 byte from 1073741824
+  Write-locking 1 byte from 1073741824
+  Write-locking 510 byte from 1073741826
+  Unlocking 2 byte from 1073741824
+info: testing umask effect on file creation
+  error: Wrong file mode 644 when creating using mode 666 and umask 000
+  error: Wrong file mode 640 when creating using mode 666 and umask 007
+&lt;/pre&gt;
+
+&lt;p&gt;So, I can conclude that sshfs is better than smb to a Netapp or a
+Windows server, but not good enough to be used as a home
+directory.&lt;/p&gt;
+
+&lt;p&gt;Update 2010-08-26: Reported the issue in
+&lt;a href=&quot;http://bugs.debian.org/594498&quot;&gt;BTS report #594498&lt;/a&gt;&lt;/p&gt;
+
+&lt;p&gt;Update 2010-08-27: Michael Gebetsroither report that he found the
+script so useful that he created a GIT repository and stored it in
+&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;My
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Automatic_upgrade_testing_from_Lenny_to_Squeeze.html&quot;&gt;testing
-of Debian upgrades&lt;/a&gt; from Lenny to Squeeze continues, and I&#39;ve
-finally made the upgrade logs available from
-&lt;a href=&quot;http://people.skolelinux.org/pere/debian-upgrade-testing/&quot;&gt;http://people.skolelinux.org/pere/debian-upgrade-testing/&lt;/a&gt;.
-I am now testing dist-upgrade of Gnome and KDE in a chroot using both
-apt and aptitude, and found their differences interesting.  This time
-I will only focus on their removal plans.&lt;/p&gt;
-
-&lt;p&gt;After installing a Gnome desktop and the laptop task, apt-get wants
-to remove 72 packages when dist-upgrading from Lenny to Squeeze.  The
-surprising part is that it want to remove xorg and all
-xserver-xorg-video* drivers.  Clearly not a good choice, but I am not
-sure why.  When asking aptitude to do the same, it want to remove 129
-packages, but most of them are library packages I suspect are no
-longer needed.  Both of them want to remove bluetooth packages, which
-I do not know.  Perhaps these bluetooth packages are obsolete?&lt;/p&gt;
-
-&lt;p&gt;For KDE, apt-get want to remove 82 packages, among them kdebase
-which seem like a bad idea and xorg the same way as with Gnome. Asking
-aptitude for the same, it wants to remove 192 packages, none which are
-too surprising.&lt;/p&gt;
-
-&lt;p&gt;I guess the removal of xorg during upgrades should be investigated
-and avoided, and perhaps others as well.  Here are the complete list
-of planned removals.  The complete logs is available from the URL
-above.  Note if you want to repeat these tests, that the upgrade test
-for kde+apt-get hung in the tasksel setup because of dpkg asking
-conffile questions.  No idea why.  I worked around it by using
-&#39;&lt;tt&gt;echo &gt;&gt; /proc/&lt;em&gt;pidofdpkg&lt;/em&gt;/fd/0&lt;/tt&gt;&#39; to tell dpkg to
-continue.&lt;/p&gt;

+&lt;p&gt;I Norge pågår en prosess for å
+&lt;a href=&quot;http://www.e-valg.dep.no/&quot;&gt;innføre elektronisk
+stemmegiving&lt;/a&gt; ved kommune- og stortingsvalg.  Dette skal
+introduseres i 2011.  Det er all grunn til å tro at valg i Norge ikke
+vil være til å stole på hvis dette blir gjennomført.  Da det hele var
+oppe til høring i 2006 forfattet jeg
+&lt;a href=&quot;http://www.nuug.no/dokumenter/valg-horing-2006-09.pdf&quot;&gt;en
+høringsuttalelse fra NUUG&lt;/a&gt; (og EFN som hengte seg på) som skisserte
+hvilke punkter som må oppfylles for at en skal kunne stole på et valg,
+og elektronisk stemmegiving mangler flere av disse.  Elektronisk
+stemmegiving er for alle praktiske formål å putte ens stemme i en sort
+boks under andres kontroll, og satse på at de som har kontroll med
+boksen er til å stole på - uten at en har mulighet til å verifisere
+dette selv.  Det er ikke slik en gjennomfører demokratiske valg.&lt;/p&gt;
+
+&lt;p&gt;Da problemet er fundamentalt med hvordan elektronisk stemmegiving
+må fungere for at også ikke-krypografer skal kunne delta, har det vært
+mange rapporter om hvordan elektronisk stemmegiving har sviktet i land
+etter land.  En
+&lt;a href=&quot;http://wiki.nuug.no/uttalelser/2006-elektronisk-stemmegiving&quot;&gt;liten
+samling referanser&lt;/a&gt; finnes på NUUGs wiki.  Den siste er fra India,
+der valgkomisjonen har valgt
+&lt;a href=&quot;http://www.freedom-to-tinker.com/blog/jhalderm/electronic-voting-researcher-arrested-over-anonymous-source&quot;&gt;å
+pusse politiet på en forsker&lt;/a&gt; som har dokumentert svakheter i
+valgsystemet.&lt;/p&gt;
+
+&lt;p&gt;Her i Norge har en valgt en annen tilnærming, der en forsøker seg
+med teknobabbel for å få befolkningen til å tro at dette skal bli
+sikkert.  Husk, elektronisk stemmegiving underminerer de demokratiske
+valgene i Norge, og bør ikke innføres.&lt;/p&gt;
+
+&lt;p&gt;Den offentlige diskusjonen blir litt vanskelig av at media har
+valgt å kalle dette &quot;evalg&quot;, som kan sies å både gjelde elektronisk
+opptelling av valget som Norge har gjort siden 60-tallet og som er en
+svært god ide, og elektronisk opptelling som er en svært dårlig ide.
+Diskusjonen gir ikke mening hvis en skal diskutere om en er for eller
+mot &quot;evalg&quot;, og jeg forsøker derfor å være klar på at jeg snakker om
+elektronisk stemmegiving og unngå begrepet &quot;evalg&quot;.&lt;/p&gt;

+&lt;p&gt;I dag fikk jeg endelig tittet litt på mine nyinnkjøpte roboter, og
+har brukt noen timer til å google etter interessante referanser og
+aktuell kildekode for bruk på Linux.  Det mest lovende så langt er
+&lt;a href=&quot;http://ispykee.toyz.org/&quot;&gt;ispykee&lt;/a&gt;, som har en
+BSD-lisensiert linux-daemon som står som mellomledd mellom roboter på
+lokalnettet og en sentral tjeneste der en iPhone kan koble seg opp for
+å fjernstyre roboten.  Linux-daemonen implementerer deler av
+protokollen som roboten forstår.  Etter å ha knotet litt med å oppnå
+kontakt med roboten (den oppretter et eget ad-hoc wifi-nett, så jeg
+måtte gå av mitt vanlige nett for å få kontakt), og kommet frem til at
+den lytter på IP-port 9000 og 9001, gikk jeg i gang med å finne ut
+hvordan jeg kunne snakke med roboten vha. disse portene.  Robotbiten
+av protokollen er publisert av produsenten med GPL-lisens, slik at det
+er mulig å se hvordan protokollen fungerer.  Det finnes en java-klient
+for Android som så ganske snasen ut, men fant ingen kildekode for
+denne.  Derimot hadde iphone-løsningen kildekode, så jeg tok
+utgangspunkt i den.&lt;/p&gt;
+
+&lt;p&gt;Daemonen ville i utgangspunktet forsøke å kontakte den sentrale
+tjenesten som iphone-programmet kobler seg til.  Jeg skrev dette om
+til i stedet å sette opp en nettverkstjeneste på min lokale maskin,
+som jeg kan koble meg opp til med telnet og gi kommandoer til roboten
+(act, forward, right, left, etc).  Det involverte i praksis å bytte ut
+socket()/connect() med socket()/bind()/listen()/accept() for å gjøre
+klienten om til en tjener.&lt;/p&gt;
+
+&lt;p&gt;Mens jeg har forsøkt å få roboten til å bevege seg har min samboer
+skrudd sammen resten av roboten for å få montert kamera og plastpynten
+(armer, plastfiber for lys).  Nå er det hele montert, og roboten er
+klar til bruk.  Må få flyttet den over til mitt vanlige trådløsnett
+før det blir praktisk, men de bitene av protokollen er ikke
+implementert i ispykee-daemonen, så der må jeg enten få tak i en mac
+eller en windows-maskin, eller implementere det selv.&lt;/p&gt;
+
+&lt;p&gt;Vi var tre som kjøpte slike roboter, og vi har blitt enige om å
+samle notater og referanser på &lt;a
+href=&quot;http://wiki.nuug.no/grupper/robot/&quot;&gt;NUUGs wiki&lt;/a&gt;.  Ta en titt
+der hvis du er nysgjerrig.&lt;/p&gt;

-&lt;p&gt;Veldig glad for å oppdage via
-&lt;a href=&quot;http://yro.slashdot.org/story/10/06/11/1841256/Finland-To-Legalize-Use-of-Unsecured-Wi-Fi&quot;&gt;Slashdot&lt;/a&gt;
-at folk i Finland har forstått at åpne trådløsnett er et samfunnsgode.
-Jeg ser på åpne trådløsnett som et fellesgode på linje med retten til
-ferdsel i utmark og retten til å bevege seg i strandsonen.  Jeg har
-glede av åpne trådløsnett når jeg finner dem, og deler gladelig nett
-med andre så lenge de ikke forstyrrer min bruk av eget nett.
-Nettkapasiteten er sjelden en begrensning ved normal browsing og enkel
-SSH-innlogging (som er min vanligste nettbruk), og nett kan brukes til
-så mye positivt og nyttig (som nyhetslesing, sjekke været, kontakte
-slekt og venner, holde seg oppdatert om politiske saker, kontakte
-organisasjoner og politikere, etc), at det for meg er helt urimelig å
-blokkere dette for alle som ikke gjør en flue fortred.  De som mener
-at potensialet for misbruk er grunn nok til å hindre all den positive
-og lovlydige bruken av et åpent trådløsnett har jeg dermed ingen
-forståelse for.  En kan ikke eksistensen av forbrytere styre hvordan
-samfunnet skal organiseres.  Da får en et kontrollsamfunn de færreste
-ønsker å leve i, og det at vi har et samfunn i Norge der tilliten til
-hverandre er høy gjør at samfunnet fungerer ganske godt.  Det bør vi
-anstrenge oss for å beholde.&lt;/p&gt;
+&lt;p&gt;Jeg kjøpte nettopp to
+&lt;a href=&quot;http://www.spykee-robot.com/&quot;&gt;Spykee&lt;/a&gt;-roboter, for test og
+leking.  Kjøpte to da det var så billige, og gir meg mulighet til å
+eksperimentere uten å være veldig redd for å ødelegge alt ved å bytte
+ut firmware og slikt.  Oppdaget at lekebutikken på Bryn senter hadde
+en liten stabel på lager som de ikke hadde klart å selge ut etter
+fjorårets juleinnkjøp, og var villig til å selge for en femtedel av
+vanlig pris.  Jeg, Ronny og Jarle har skaffet oss restbeholdningen, og
+det blir morsomt å se hva vi får ut av dette.&lt;/p&gt;
+
+&lt;p&gt;Roboten har belter styrt av to motorer, kamera, høytaler, mikrofon
+og wifi-tilkobling.  Det hele styrt av en GPL-lisensiert databoks som
+jeg mistenker kjører linux.  Firmware-kildekoden ble visst publisert i
+mai.  Eneste utfordringen er at kontroller-programvaren kun finnes til
+Windows, men det må en kunne jobbe seg rundt når vi har kildekoden til
+firmwaren. :)&lt;/p&gt;
