-      <div class="date">17th July 2013</div>

-<a href="http://people.skolelinux.org/pere/blog/The_Thinkpad_is_dead__long_live_the_Thinkpad_X230_.html">my
-new laptop</a>.  I've previously written about the problems I had with
-my new Thinkpad X230, which was delivered with an
-<a href="http://people.skolelinux.org/pere/blog/Intel_SSD_520_Series_180_GB_with_Lenovo_firmware_still_lock_up_from_sustained_writes.html">180
-GB Intel SSD disk with Lenovo firmware</a> that did not handle
-sustained writes.  My hardware supplier have been very forthcoming in
-trying to find a solution, and after first trying with another
-identical 180 GB disks they decided to send me a 256 GB Samsung SSD
-disk instead to fix it once and for all.  The Samsung disk survived
-the installation of Debian with encrypted disks (filling the disk with
-random data during installation killed the first two), and I thus
-decided to trust it with my data.  I have installed it as a Debian Edu
-Wheezy roaming workstation hooked up with my Debian Edu Squeeze main
-server at home using Kerberos and LDAP, and will use it as my work
-station from now on.</p>
-
-<p>As this is a solid state disk with no moving parts, I believe the
-Debian Wheezy default installation need to be tuned a bit to increase
-performance and increase life time of the disk.  The Linux kernel and
-user space applications do not yet adjust automatically to such
-environment.  To make it easier for my self, I created a draft Debian
-package <tt>ssd-setup</tt> to handle this tuning.  The
-<a href="http://anonscm.debian.org/gitweb/?p=collab-maint/ssd-setup.git">source
-for the ssd-setup package</a> is available from collab-maint, and it
-is set up to adjust the setup of the machine by just installing the
-package.  If there is any non-SSD disk in the machine, the package
-will refuse to install, as I did not try to write any logic to sort
-file systems in SSD and non-SSD file systems.</p>
-
-<p>I consider the package a draft, as I am a bit unsure how to best
-set up Debian Wheezy with an SSD.  It is adjusted to my use case,
-where I set up the machine with one large encrypted partition (in
-addition to /boot), put LVM on top of this and set up partitions on
-top of this again.  See the README file in the package source for the
-references I used to pick the settings.  At the moment these
-parameters are tuned:</p>
-
-<ul>
-
-<li>Set up cryptsetup to pass TRIM commands to the physical disk
-    (adding discard to /etc/crypttab)</li>
-
-<li>Set up LVM to pass on TRIM commands to the underlying device (in
-    this case a cryptsetup partition) by changing issue_discards from
-    0 to 1 in /etc/lvm/lvm.conf.</li>
-
-<li>Set relatime as a file system option for ext3 and ext4 file
-    systems.</li>
-
-<li>Tell swap to use TRIM commands by adding 'discard' to
-    /etc/fstab.</li>
-
-<li>Change I/O scheduler from cfq to deadline using a udev rule.</li>
-
-<li>Run fstrim on every ext3 and ext4 file system every night (from
-    cron.daily).</li>
-
-<li>Adjust sysctl values vm.swappiness to 1 and vm.vfs_cache_pressure
-    to 50 to reduce the kernel eagerness to swap out processes.</li>
-
-</ul>
-
-<p>During installation, I cancelled the part where the installer fill
-the disk with random data, as this would kill the SSD performance for
-little gain.  My goal with the encrypted file system is to ensure
-those stealing my laptop end up with a brick and not a working
-computer.  I have no hope in keeping the really resourceful people
-from getting the data on the disk (see
-<a href="http://xkcd.com/538/">XKCD #538</a> for an explanation why).
-Thus I concluded that adding the discard option to crypttab is the
-right thing to do.</p>
-
-<p>I considered using the noop I/O scheduler, as several recommended
-it for SSD, but others recommended deadline and a benchmark I found
-indicated that deadline might be better for interactive use.</p>
-
-<p>I also considered using the 'discard' file system option for ext3
-and ext4, but read that it would give a performance hit ever time a
-file is removed, and thought it best to that that slowdown once a day
-instead of during my work.</p>
-
-<p>My package do not set up tmpfs on /var/run, /var/lock and /tmp, as
-this is already done by Debian Edu.</p>
-
-<p>I have not yet started on the user space tuning.  I expect
-iceweasel need some tuning, and perhaps other applications too, but
-have not yet had time to investigate those parts.</p>
-
-<p>The package should work on Ubuntu too, but I have not yet tested it
-there.</p>
-
-<p>As for the answer to the question in the title of this blog post,
-as far as I know, the only solution is to replace the disk.  It might
-be possible to flash it with Intel firmware instead of the Lenovo
-firmware.  But I have not tried and did not want to do so without
-approval from Lenovo as I wanted to keep the warranty on the disk
-until a solution was found and they wanted the broken disks back.</p>

+making it easy for non-technical people to host their data and
+communication at home, and being able to communicate with their
+friends and family encrypted and away from prying eyes.  It has been
+going on for a while, and is slowly progressing towards a new test
+release (0.2).</p>
+
+<p>And what day could be better than the Pi day to announce that the
+new version will provide "hard drive" / SD card / USB stick images for
+Dreamplug, Raspberry Pi and VirtualBox (or any other virtualization
+system), and can also be installed using a Debian installer preseed
+file.  The Debian based Freedombox is now based on Debian Jessie,
+where most of the needed packages used are already present.  Only one,
+the freedombox-setup package, is missing.  To try to build your own
+boot image to test the current status, fetch the freedom-maker scripts
+and build using
+<a href="http://packages.qa.debian.org/vmdebootstrap">vmdebootstrap</a>
+with a user with sudo access to become root:
+
+<pre>
+git clone http://anonscm.debian.org/git/freedombox/freedom-maker.git \
+  freedom-maker
+sudo apt-get install git vmdebootstrap mercurial python-docutils \
+  mktorrent extlinux virtualbox qemu-user-static binfmt-support \
+  u-boot-tools
+make -C freedom-maker dreamplug-image raspberry-image virtualbox-image
+</pre>
+
+<p>Root access is needed to run debootstrap and mount loopback
+devices.  See the README for more details on the build. If you do not
+want all three images, trim the make line.  But note that thanks to <a
+href="https://bugs.debian.org/741407">a race condition in
+vmdebootstrap</a>, the build might fail without the patch to the
+kpartx call.</p>
+
+<p>If you instead want to install using a Debian CD and the preseed
+method, boot a Debian Wheezy ISO and use this boot argument to load
+the preseed values:</p>
+
+<pre>
+url=<a href="http://www.reinholdtsen.name/freedombox/preseed-jessie.dat">http://www.reinholdtsen.name/freedombox/preseed-jessie.dat</a>
+</pre>
+
+<p>But note that due to <a href="https://bugs.debian.org/740673">a
+recently introduced bug in apt in Jessie</a>, the installer will
+currently hang while setting up APT sources.  Killing the
+'<tt>apt-cdrom ident</tt>' process when it hang a few times during the
+installation will get the installation going.  This affect all
+installations in Jessie, and I expect it will be fixed soon.</p>
+
+Give it a go and let us know how it goes on the mailing list, and help
+us get the new release published. :) Please join us on

+      <div class="date">12th March 2014</div>
+      <div class="body"><p>On larger sites, it is useful to use a dedicated storage server for
+storing user home directories and data.  The design for handling this
+in <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a>, is
+to update the automount rules in LDAP and let the automount daemon on
+the clients take care of the rest.  I was reminded about the need to
+document this better when one of the customers of
+<a href="http://www.slxdrift.no/">Skolelinux Drift AS</a>, where I am
+on the board of directors, asked about how to do this.  The steps to
+get this working are the following:</p>
+
+<p><ol>
+
+<li>Add new storage server in DNS.  I use nas-server.intern as the
+example host here.</li>
+
+<li>Add automoun LDAP information about this server in LDAP, to allow
+all clients to automatically mount it on reqeust.</li>
+
+<li>Add the relevant entries in tjener.intern:/etc/fstab, because
+tjener.intern do not use automount to avoid mounting loops.</li>
+
+</ol></p>
+
+<p>DNS entries are added in GOsa², and not described here.  Follow the
+<a href="https://wiki.debian.org/DebianEdu/Documentation/Wheezy/GettingStarted">instructions
+in the manual</a> (Machine Management with GOsa² in section Getting
+started).</p>
+
+<p>Ensure that the NFS export points on the server are exported to the
+relevant subnets or machines:</p>
+
+<p><blockquote><pre>
+root@tjener:~# showmount -e nas-server
+Export list for nas-server:
+/storage         10.0.0.0/8
+root@tjener:~#
+</pre></blockquote></p>
+
+<p>Here everything on the backbone network is granted access to the
+/storage export.  With NFSv3 it is slightly better to limit it to
+netgroup membership or single IP addresses to have some limits on the
+NFS access.</p>
+
+<p>The next step is to update LDAP.  This can not be done using GOsa²,
+because it lack a module for automount.  Instead, use ldapvi and add
+the required LDAP objects using an editor.</p>
+
+<p><blockquote><pre>
+ldapvi --ldap-conf -ZD '(cn=admin)' -b ou=automount,dc=skole,dc=skolelinux,dc=no
+</pre></blockquote></p>
+
+<p>When the editor show up, add the following LDAP objects at the
+bottom of the document.  The "/&" part in the last LDAP object is a
+wild card matching everything the nas-server exports, removing the
+need to list individual mount points in LDAP.</p>
+
+<p><blockquote><pre>
+add cn=nas-server,ou=auto.skole,ou=automount,dc=skole,dc=skolelinux,dc=no
+objectClass: automount
+cn: nas-server
+automountInformation: -fstype=autofs --timeout=60 ldap:ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
+
+add ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
+objectClass: top
+objectClass: automountMap
+ou: auto.nas-server
+
+add cn=/,ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
+objectClass: automount
+cn: /
+automountInformation: -fstype=nfs,tcp,rsize=32768,wsize=32768,rw,intr,hard,nodev,nosuid,noatime nas-server.intern:/&
+</pre></blockquote></p>
+
+<p>The last step to remember is to mount the relevant mount points in
+tjener.intern by adding them to /etc/fstab, creating the mount
+directories using mkdir and running "mount -a" to mount them.</p>
+
+<p>When this is done, your users should be able to access the files on
+the storage server directly by just visiting the
+/tjener/nas-server/storage/ directory using any application on any
+workstation, LTSP client or LTSP server.</p>

+      <div class="date"> 7th March 2014</div>
+      <div class="body"><p>For noen uker siden ble NXCs fri programvarelisenserte
+NOARK5-løsning
+<a href="http://www.nuug.no/aktiviteter/20140211-noark/">presentert hos
+NUUG</a> (video
+<a href="https://www.youtube.com/watch?v=JCb_dNS3MHQ">på youtube
+foreløbig</a>), og det fikk meg til å titte litt mer på NOARK5,
+standarden for arkivhåndtering i det offentlige Norge.  Jeg lurer på
+om denne kjernen kan være nyttig i et par av mine prosjekter, og for ett
+av dem er det mest aktuelt å lagre epost.  Jeg klarte ikke finne noen
+anbefaling om hvordan RFC 822-formattert epost (aka Internett-epost)
+burde lagres i NOARK5, selv om jeg vet at noen arkiver tar
+PDF-utskrift av eposten med sitt epostprogram og så arkiverer PDF-en
+(eller enda værre, tar papirutskrift og lagrer bildet av eposten som
+PDF i arkivet).</p>
+
+<p>Det er ikke så mange formater som er akseptert av riksarkivet til
+langtidsoppbevaring av offentlige arkiver, og PDF og XML er de mest
+aktuelle i så måte.  Det slo meg at det måtte da finnes en eller annen
+egnet XML-representasjon og at det kanskje var enighet om hvilken som
+burde brukes, så jeg tok mot til meg og spurte
+<a href="http://samdok.com/">SAMDOK</a>, en gruppe tilknyttet
+arkivverket som ser ut til å jobbe med NOARK-samhandling, om de hadde
+noen anbefalinger:
+
+<p><blockquote>
+<p>Hei.</p>
+
+<p>Usikker på om dette er riktig forum å ta opp mitt spørsmål, men jeg
+lurer på om det er definert en anbefaling om hvordan RFC
+822-formatterte epost (aka vanlig Internet-epost) bør lages håndteres
+i NOARK5, slik at en bevarer all informasjon i eposten
+(f.eks. Received-linjer).  Finnes det en anbefalt XML-mapping ala den
+som beskrives på
+&lt;URL: <a href="https://www.informit.com/articles/article.aspx?p=32074">https://www.informit.com/articles/article.aspx?p=32074</a> &gt;?  Mitt
+mål er at det skal være mulig å lagre eposten i en NOARK5-kjerne og
+kunne få ut en identisk formattert kopi av opprinnelig epost ved
+behov.</p>
+</blockquote></p>
+
+<p>Postmottaker hos SAMDOK mente spørsmålet heller burde stilles
+direkte til riksarkivet, og jeg fikk i dag svar derfra formulert av
+seniorrådgiver Geir Ivar Tungesvik:</p>
+
+<p><blockquote>
+<p>Riksarkivet har ingen anbefalinger når det gjelder konvertering fra
+e-post til XML.  Det står arkivskaper fritt å eventuelt definere/bruke
+eget format.  Inklusive da - som det spørres om - et format der det er
+mulig å re-etablere e-post format ut fra XML-en.  XML (e-post)
+dokumenter må være referert i arkivstrukturen, og det må vedlegges et
+gyldig XML skjema (.xsd) for XML-filene. Arkivskaper står altså fritt
+til å gjøre hva de vil, bare det dokumenteres og det kan dannes et
+utrekk ved avlevering til depot.</p>
+
+<p>De obligatoriske kravene i Noark 5 standarden må altså oppfylles -
+etter dialog med Riksarkivet i forbindelse med godkjenning. For
+offentlige arkiv er det særlig viktig med filene loependeJournal.xml
+og offentligJournal.xml. Private arkiv som vil forholde seg til Noark
+5 standarden er selvsagt frie til å bruke det som er relevant for dem
+av obligatoriske krav.</p>
+</blockquote></p>
+
+<p>Det ser dermed ut for meg som om det er et lite behov for å
+standardisere XML-lagring av RFC-822-formatterte meldinger.  Noen som
+vet om god spesifikasjon i så måte?  I tillegg til den omtalt over,
+har jeg kommet over flere aktuelle beskrivelser (søk på "rfc 822
+xml", så finner du aktuelle alternativer).</p>
+
+<ul>
+
+<li><a href="http://www.openhealth.org/xmtp/">XML MIME Transformation
+protocol (XMTP)</a> fra OpenHealth, sist oppdatert 2001.</li>

-      <div class="date"> 5th July 2013</div>
-      <div class="body"><p>Half a year ago, I reported that I had to find a
-<a href="http://people.skolelinux.org/pere/blog/Thank_you_Thinkpad_X41__for_your_long_and_trustworthy_service.html">replacement
-for my trusty old Thinkpad X41</a>.  Unfortunately I did not have much
-time to spend on it, and it took a while to find a model I believe
-will do the job, but two days ago the replacement finally arrived.  I
-ended up picking a
-<a href="http://www.linlap.com/lenovo_thinkpad_x230">Thinkpad X230</a>
-with SSD disk (NZDAJMN).  I first test installed Debian Edu Wheezy as
-a roaming workstation, and it seemed to work flawlessly.  But my
-second installation with encrypted disk was not as successful.  More
-on that below.</p>
-
-<p>I had a hard time trying to track down a good laptop, as my most
-important requirements (robust and with a good keyboard) are never
-listed in the feature list.  But I did get good help from the search
-feature at <a href="http://www.prisjakt.no/">Prisjakt</a>, which
-allowed me to limit the list of interesting laptops based on my other
-requirements.  A bit surprising that SSD disk are not disks according
-to that search interface, so I had to drop specifying the number of
-disks from my search parameters.  I also asked around among friends to
-get their impression on keyboards and robustness.</p>
-
-<p>So the new laptop arrived, and it is quite a lot wider than the
-X41.  I am not quite convinced about the keyboard, as it is
-significantly wider than my old keyboard, and I have to stretch my
-hand a lot more to reach the edges.  But the key response is fairly
-good and the individual key shape is fairly easy to handle, so I hope
-I will get used to it.  My old X40 was starting to fail, and I really
-needed a new laptop now. :)</p>
-
-<p>Turning off the touch pad was simple.  All it took was a quick
-visit to the BIOS during boot it disable it.</p>
-
-<p>But there is a fatal problem with the laptop.  The 180 GB SSD disk
-lock up during load.  And this happen when installing Debian Wheezy
-with encrypted disk, while the disk is being filled with random data.
-I also tested to install Ubuntu Raring, and it happen there too if I
-reenable the code to fill the disk with random data (it is disabled by
-default in Ubuntu).  And the bug with is already known.  It was
-reported to Debian as <a href="http://bugs.debian.org/691427">BTS
-report #691427 2012-10-25</a> (journal commit I/O error on brand-new
-Thinkpad T430s ext4 on lvm on SSD).  It is also reported to the Linux
-kernel developers as
-<a href="https://bugzilla.kernel.org/show_bug.cgi?id=51861">Kernel bugzilla
-report #51861 2012-12-20</a> (Intel SSD 520 stops working under load
-(SSDSC2BW180A3L in Lenovo ThinkPad T430s)). It is also reported on the
-Lenovo forums, both for
-<a href="http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T430s-Intel-SSD-520-180GB-issue/m-p/1070549">T430

-03-20-2013</a>.  The problem do not only affect installation.  The
-reports state that the disk lock up during use if many writes are done
-on the disk, so it is much no use to work around the installation
-problem and end up with a computer that can lock up at any moment.
-There is even a
-<a href="https://git.efficios.com/?p=test-ssd.git">small C program
-available</a> that will lock up the hard drive after running a few
-minutes by writing to a file.</p>
-
-<p>I've contacted my supplier and asked how to handle this, and after
-contacting PCHELP Norway (request 01D1FDP) which handle support
-requests for Lenovo, his first suggestion was to upgrade the disk
-firmware.  Unfortunately there is no newer firmware available from
-Lenovo, as my disk already have the most recent one (version LF1i).  I
-hope to hear more from him today and hope the problem can be
-fixed. :)</p>

-<p><strong>About Debian Edu and Skolelinux</strong></p>
-
-<p><a href="http://www.skolelinux.org/">Debian Edu, also known as
-Skolelinux</a>, is a Linux distribution based on Debian providing an
-out-of-the box environment of a completely configured school
-network. Immediately after installation a school server running all
-services needed for a school network is set up just waiting for users
-and machines being added via GOsa², a comfortable Web-UI. A netbooting
-environment is prepared using PXE, so after initial installation of
-the main server from CD, DVD or USB stick all other machines can be
-installed via the network. The provided school server provides LDAP
-database and Kerberos authentication service, centralized home
-directories, DHCP server, web proxy and many other services. The
-desktop contains
-<a href="http://people.skolelinux.org/pere/blog/Educational_applications_included_in_Debian_Edu___Skolelinux__the_screenshot_collection____.html">more
-than 60 educational software packages</a> and more are available from
-the Debian archive, and schools can choose between KDE, Gnome, LXDE
-and Xfce desktop environment.</p>
-
-<p>This is the fourth test release based on Debian Wheezy. Basically
-this is an updated and slightly improved version compared to the
-Squeeze release.</p>
-
-<p><strong>Software updates</strong></p>
-<ul>
-  <li>Dropped ispell dictionaries from our default installation.</li>
-  <li>Dropped menu-xdg from the KDE desktop option, to drop the Debian
-    submenu.  It was not included with Gnome, LXDE or Xfce, so this
-    brings KDE in line with the others.</li>
-  <li>Dropped xdrawchem, xjig and xsok from our default installation as
-    they don't have a desktop menu entry and thus won't show up in the
-    menu now that menu-xdg was removed.</li>
-  <li>Removed the killer system to kill left behind processes on
-    multi-user machines, as it was no longer able to understand when a
-    X display was in use and killed the processes of the active users
-    too.</li>
-  <li>Dropped the golearn (from goplay) package as the debtags in wheezy
-    are too few to make the package useful.</li>
-</ul>
-<p><strong>Other changes</strong></p>
-<ul>
-  <li>Updated artwork matching http://wiki.debian.org/DebianArt/Themes/Joy
-  <li>Multi-arch i386/amd64 USB stick ISO available.</li>
-  <li>Got rid of ispell/wordlist related debconf questions that showed
-    up for some language options.</li>
-  <li>Switched to using http.debian.net as APT source by default.</li>
-  <li>Fixed proxy configuration on Main Server installations.</li>
-  <li>Changed LTSP setup to ask dpkg to use force-unsafe-io the same way
-    d-i is doing it.</li>
-  <li>Made sure root and user passwords were not left behind in the
-    debconf database after installation on Main Server installations.</li>
-  <li>Made Roaming Workstation dynamic setup more robust and added draft
-    script setup-ad-client to hook a Roaming Workstation up to a
-    Active Directory server instead of a Debian Edu Main Server.</li>
-  <li>Update system to install needed firmware packages during
-    installation, to work properly in Wheezy.</li>
-  <li>Update system to handle hardware quirks (debian-edu-hwsetup).</li>
-  <li>Corrected PXE installation setup to properly pass selected desktop
-    and keymap settings to PXE installation clients.</li>
-  <li>LTSP diskless workstations use sshfs by default, allowing them to
-    work without adding them to DNS and NIS netgroups for NFS access.</li>
-</ul>
-<p><strong>Known issues</strong></p>
-<ul>
-  <li>No mass import of user account data in GOsa (ldif or csv)
-    available yet (698840).</li>

+      <div class="body"><p>A few days ago I decided to try to help the Hurd people to get
+their changes into sysvinit, to allow them to use the normal sysvinit
+boot system instead of their old one.  This follow up on the
+<a href="https://teythoon.cryptobitch.de//categories/gsoc.html">great
+Google Summer of Code work</a> done last summer by Justus Winter to
+get Debian on Hurd working more like Debian on Linux.  To get started,
+I downloaded a prebuilt hard disk image from
+<a href="http://ftp.debian-ports.org/debian-cd/hurd-i386/current/debian-hurd.img.tar.gz">http://ftp.debian-ports.org/debian-cd/hurd-i386/current/debian-hurd.img.tar.gz</a>,
+and started it using virt-manager.</p>
+
+<p>The first think I had to do after logging in (root without any
+password) was to get the network operational.  I followed
+<a href="https://www.debian.org/ports/hurd/hurd-install">the
+instructions on the Debian GNU/Hurd ports page</a> and ran these
+commands as root to get the machine to accept a IP address from the
+kvm internal DHCP server:</p>
+
+<p><blockquote><pre>
+settrans -fgap /dev/netdde /hurd/netdde
+kill $(ps -ef|awk '/[p]finet/ { print $2}')

+<p>After this, the machine had internet connectivity, and I could
+upgrade it and install the sysvinit packages from experimental and
+enable it as the default boot system in Hurd.</p>
+
+<p>But before I did that, I set a password on the root user, as ssh is
+running on the machine it for ssh login to work a password need to be
+set.  Also, note that a bug somewhere in openssh on Hurd block
+compression from working.  Remember to turn that off on the client
+side.</p>
+
+<p>Run these commands as root to upgrade and test the new sysvinit
+stuff:</p>
+
+<p><blockquote><pre>
+cat > /etc/apt/sources.list.d/experimental.list &lt;&lt;EOF
+deb http://http.debian.net/debian/ experimental main
+EOF
+apt-get update
+apt-get dist-upgrade
+apt-get install -t experimental initscripts sysv-rc sysvinit \
+    sysvinit-core sysvinit-utils
+update-alternatives --config runsystem
+</pre></blockquote></p>
+
+<p>To reboot after switching boot system, you have to use
+<tt>reboot-hurd</tt> instead of just <tt>reboot</tt>, as there is not
+yet a sysvinit process able to receive the signals from the normal
+'reboot' command.  After switching to sysvinit as the boot system,
+upgrading every package and rebooting, the network come up with DHCP
+after boot as it should, and the settrans/pkill hack mentioned at the
+start is no longer needed.  But for some strange reason, there are no
+longer any login prompt in the virtual console, so I logged in using
+ssh instead.
+
+<p>Note that there are some race conditions in Hurd making the boot
+fail some times.  No idea what the cause is, but hope the Hurd porters
+figure it out.  At least Justus said on IRC (#debian-hurd on
+irc.debian.org) that they are aware of the problem.  A way to reduce
+the impact is to upgrade to the Hurd packages built by Justus by
+adding this repository to the machine:</p>
+
+<p><blockquote><pre>
+cat > /etc/apt/sources.list.d/hurd-ci.list &lt;&lt;EOF
+deb http://darnassus.sceen.net/~teythoon/hurd-ci/ sid main
+EOF
+</pre></blockquote></p>
+
+<p>At the moment the prebuilt virtual machine get some packages from
+http://ftp.debian-ports.org/debian, because some of the packages in
+unstable do not yet include the required patches that are lingering in
+BTS.  This is the completely list of "unofficial" packages installed:</p>
+
+<p><blockquote><pre>
+# aptitude search '?narrow(?version(CURRENT),?origin(Debian Ports))'
+i   emacs                   - GNU Emacs editor (metapackage)
+i   gdb                     - GNU Debugger
+i   hurd-recommended        - Miscellaneous translators
+i   isc-dhcp-client         - ISC DHCP client
+i   isc-dhcp-common         - common files used by all the isc-dhcp* packages

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

-including a new script isenkram-autoinstall-firmware handling the
-process of asking all the loaded kernel modules what firmware files
-they want, find debian packages providing these files and install the
-debian packages.  Here is a test run on my laptop:</p>
-
-<p><pre>

-</pre></p>
-
-<p>It could use some polish, but it is already working well and saving
-me some time when setting up new machines. :)</p>
-
-<p>So, how does it work?  It look at the set of currently loaded
-kernel modules, and look up each one of them using modinfo, to find
-the firmware files listed in the module meta-information.  Next, it
-download the Contents file from a nearby APT mirror, and search for
-the firmware files in this file to locate the package with the
-requested firmware file.  If the package is in the non-free section, a
-non-free APT source is added and the package is installed using
-<tt>apt-get install</tt>.  The end result is a slightly better working
-machine.</p>
-
-<p>I hope someone find time to implement a more polished version of

+      <div class="body"><p>Bitcoin is a incredible use of peer to peer communication and
+encryption, allowing direct and immediate money transfer without any
+central control.  It is sometimes claimed to be ideal for illegal
+activity, which I believe is quite a long way from the truth.  At least
+I would not conduct illegal money transfers using a system where the
+details of every transaction are kept forever.  This point is
+investigated in
+<a href="https://www.usenix.org/publications/login">USENIX ;login:</a>
+from December 2013, in the article
+"<a href="https://www.usenix.org/system/files/login/articles/03_meiklejohn-online.pdf">A
+Fistful of Bitcoins - Characterizing Payments Among Men with No
+Names</a>" by Sarah Meiklejohn, Marjori Pomarole,Grant Jordan, Kirill
+Levchenko, Damon McCoy, Geoffrey M. Voelker, and Stefan Savage.  They
+analyse the transaction log in the Bitcoin system, using it to find
+addresses belong to individuals and organisations and follow the flow
+of money from both Bitcoin theft and trades on Silk Road to where the
+money end up.  This is how they wrap up their article:</p>
+
+<p><blockquote>
+<p>"To demonstrate the usefulness of this type of analysis, we turned
+our attention to criminal activity. In the Bitcoin economy, criminal
+activity can appear in a number of forms, such as dealing drugs on
+Silk Road or simply stealing someone else’s bitcoins. We followed the
+flow of bitcoins out of Silk Road (in particular, from one notorious
+address) and from a number of highly publicized thefts to see whether
+we could track the bitcoins to known services. Although some of the
+thieves attempted to use sophisticated mixing techniques (or possibly
+mix services) to obscure the flow of bitcoins, for the most part
+tracking the bitcoins was quite straightforward, and we ultimately saw
+large quantities of bitcoins flow to a variety of exchanges directly
+from the point of theft (or the withdrawal from Silk Road).</p>
+
+<p>As acknowledged above, following stolen bitcoins to the point at
+which they are deposited into an exchange does not in itself identify
+the thief; however, it does enable further de-anonymization in the
+case in which certain agencies can determine (through, for example,
+subpoena power) the real-world owner of the account into which the
+stolen bitcoins were deposited.  Because such exchanges seem to serve
+as chokepoints into and out of the Bitcoin economy (i.e., there are
+few alternative ways to cash out), we conclude that using Bitcoin for
+money laundering or other illicit purposes does not (at least at
+present) seem to be particularly attractive."</p>
+</blockquote><p>
+
+<p>These researches are not the first to analyse the Bitcoin
+transaction log.  The 2011 paper
+"<a href="http://arxiv.org/abs/1107.4524">An Analysis of Anonymity in
+the Bitcoin System</A>" by Fergal Reid and Martin Harrigan is
+summarized like this:</p>
+
+<p><blockquote>
+"Anonymity in Bitcoin, a peer-to-peer electronic currency system, is a
+complicated issue. Within the system, users are identified by
+public-keys only. An attacker wishing to de-anonymize its users will
+attempt to construct the one-to-many mapping between users and
+public-keys and associate information external to the system with the
+users. Bitcoin tries to prevent this attack by storing the mapping of
+a user to his or her public-keys on that user's node only and by
+allowing each user to generate as many public-keys as required. In
+this chapter we consider the topological structure of two networks
+derived from Bitcoin's public transaction history. We show that the
+two networks have a non-trivial topological structure, provide
+complementary views of the Bitcoin system and have implications for
+anonymity. We combine these structures with external information and
+techniques such as context discovery and flow analysis to investigate
+an alleged theft of Bitcoins, which, at the time of the theft, had a
+market value of approximately half a million U.S. dollars."
+</blockquote></p>
+
+<p>I hope these references can help kill the urban myth that Bitcoin
+is anonymous.  It isn't really a good fit for illegal activites.  Use
+cash if you need to stay anonymous, at least until regular DNA
+sampling of notes and coins become the norm. :)</p>
+
+<p>As usual, if you use Bitcoin and want to show your support of my
+activities, please send Bitcoin donations to my address

 <p><strong>Who are you, and how do you spend your days?</strong></p>
 
-<p>I'm a 25 year old free software enthusiast, living in Romania,
-which is also my country of origin. Back in 2009, at a New Year's Eve
-party, I had a very nice <strike>beer</strike> discussion with a
-friend, when we realized we have no organised Debian community in our
-country. A few days later, we put together the infrastructure for such
-community and even gathered a nice Debian-ish crowd. Since then, I
-began my quest as a free software hacker and activist and I am
-constantly trying to cover as much ground as possible on that
-field.</p>
-
-<p>A few years ago I founded a small web development company, which
-provided me the flexible schedule I needed so much for my
-activities. For the last 13 months, I have been the Technical Director
-of <a href="http://ceata.org/">Fundația Ceata</a>, which is a free
-software activist organisation endorsed by the FSF and the FSFE, and
-the only one we have in our country.</p>
+<p>I am a 23 year-old student from Germany who has spent half of his
+life with open source. In "real life", I am, as already mentioned, a
+student in the fields of Computer Science, Electrical Engineering,
+Information Technologies and Anglistics. Due to my (only partially
+voluntary) huge engagement in the open source world, these things are
+a bit vacant right now however.</p>
+
+<p>I also have been working as a project teacher at a Gymasnium
+(public school) for various years now. I took up that work some time
+around 2005 when still attending that school myself and have continued
+it until today. I also had been running the (kind of very advanced)
+network of that school together with a team of very interested and
+talented students in the age of 11 to 15 years, who took the chance to
+learn a lot about open source and networking before I left the school
+to help building another school's informational education concept from
+scratch.</p>
+
+<p>That said, one might see me as a kind of "glue" between school kids
+and the elderly of teachers as well as between the open source
+ecosystem and the (even more complex) educational ecosystem.</p>
+
+<p>When I am not busy with open source or education, I like Geocaching
+and cycling.</p>
 
 <p><strong>How did you get in contact with the Skolelinux / Debian Edu
 project?</strong></p>
 
-<p>The idea of participating in the Debian Edu project was a surprise
-even to me, since I never used it before I began getting involved in
-it. This year I had a great opportunity to deliver a talk on
-educational software, and I knew immediately where to look. It was a
-love at first sight, since I was previously involved with some of the
-technologies the project incorporates, and I rapidly found a lot of
-ways to contribute.</p>
-
-<p>My first contributions consisted in translating the installer and
-configuration dialogs, then I found some bugs to squash (I still
-haven't fixed them yet though), and I even got my eyes on some other
-areas where I can prove myself helpful. Since the appetite for free
-software in my country is pretty low, I'll be happy to be the first
-one around here advocating for the project's adoption in educational
-environments, and maybe even get my hands dirty in creating a flavour
-for our own needs. I am not used to make very advanced plannings, so
-from now on, time will tell what I'll be doing next, but I think I
-have a pretty consistent starting point.</p>
-
-<p><strong>What do you see as the advantages of Skolelinux/Debian
+<p>I think that happened some time around 2009 when I first attended
+<a href="http://www.froscon.org">FrOSCon</a> and visited the project
+booth. I think I wasn't too interested back then because I used to
+have an attitude of disliking software that does too much stuff on its
+own. Maybe I was too inexperienced to realise the upsides of an
+"out-of-the-box" solution ;).</p>
+
+<p>The first time I actively talked to Skolelinux people was at
+<a href="http://www.openrheinruhr.de">OpenRheinRuhr</a> 2011 when the
+BiscuIT project, a home-grewn software used by my school for various
+really cool things from timetables and class contact lists to lunch
+ordering, student ID card printing and project elections first got to
+a stage where it could have been published. I asked the Skolelinux
+guys running the booth if the project were interested in it and gave a
+small demonstration, but there wasn't any real feedback and the guys
+seemed rather uninterested.</p>
+
+<p>After I left the school where I developed the software, it got
+mostly lost, but I am now reimplementing it for my new school. I have
+reusability and compatibility in mind, and I hop there will be a new
+basis for contributing it to the Skolelinux project ;)!</p>
+
+<p><strong>What do you see as the advantages of Skolelinux / Debian
 Edu?</strong></p>
 
-<p>Not a long time ago, I was in the position of configuring and
-maintaining a LDAP server on some Debian derivative, and I must say it
-took me a while. A long time ago, I was maintaining a bigger
-Samba-powered infrastructure, and I must say I spent quite a lot of
-time on it. I have similar stories about many of the services included
-with Skolelinux, and the main advantage I see about it is the
-out-of-the box availability of them, making it quite competitive when
-it comes to managing a school's network, for example.</p>
-
-<p>Of course, there is more to say about Skolelinux than the
-availability of the software included, its flexibility in various
-scenarios is something I can't wait to experiment "into the wild" (I
-only played with virtual machines so far). And I am sure there is a
-lot more I haven't discovered yet about it, being so new within the
-project.</p>
+<p>The most important advantage seems to be that it "just
+works". After overcoming some minor (but still very annoying) glitches
+in the installer, I got a fully functional, working school network,
+without the month-long hassle I experienced when setting all that up
+from scratch in earlier years. And above that, it rocked - I didn't
+have any real hardware at hand, because the school was just founded
+and has no money whatsoever, so I installed a combined server (main
+server, terminal services and workstation) in a VM on my personal
+notebook, bridging the LTSP network interface to the ethernet port,
+and then PXE-booted the Windows notebooks that were lying around from
+it. I could use 8 clients without any performance issues, by using a
+tiny little VM on a tiny little notebook. I think that's enough to say
+that it rocks!</p>
+
+<p>Secondly, there are marketing reasons. Life's bad, and so no
+politician will ever permit a setup described as "Debian, an universal
+operating system, with some really cool educational tools" while they
+will be jsut fine with "Skolelinux, a single-purpose solution for your
+school network", even if both turn out to be the very same thing (yes,
+this is unfair towards the Skolelinux project, and must not be taken
+too seriously - you get the idea, anyway).</p>
 
 <p><strong>What do you see as the disadvantages of Skolelinux / Debian
 Edu?</strong></p>
 
-<p>As usual, when it comes to Debian Blends, I see as the biggest
-disadvantage the lack of a numerous team dedicated to the
-project. Every day I see the same names in the changelogs, and I have
-a constantly fear of the bus factor in this story.  I'd like to see
-Debian Edu advertised more as an entry point into the Debian
-ecosystem, especially amongst newcomers and students. IMHO there are a
-lot low-hanging fruits in terms of bug squashing, and enough
-opportunities to get the feeling of the Debian Project's dynamics. Not
-to mention it's a very fun blend to work on!</p>
-
-<p>Derived from the previous statement, is the delay in catching up
-with the main Debian release and documentation. This is common though
-to all blends and derivatives, but it's an issue we can all work
-on.</p>
-
-<p><strong>Which free software do you use daily?</strong></p>
-
-<p>I can hardly imagine myself spending a day without Vim, since my
-daily routine covers writing code and hacking configuration files. I
-am a fan of the Awesome window manager (but I also like the
-Enlightenment project a lot!),
-<a href="http://www.claws-mail.org/‎">Claws Mail</a> due to its ease of
-use and very configurable behaviour. Recently I fell in love with
-<a href="https://launchpad.net/redshift">Redshift</a>, which helps me
-get through the night without headaches. Of course, there is much more
-stuff in this bag, but I'll need a blog on my own for doing this!</p>
-
-<p><strong>Which strategy do you believe is the right one to use to
-get schools to use free software?</strong></p>
-
-<p>Well, on this field, I cannot do much more than experiment right
-now. So, being far from having a recipe for success, I can only assume
-that:</p>
+<p>I have not been involved with Skolelinux long enough to really
+answer this question in a fair way. Thus, please allow me to put it in
+other words: "What do you expect from Skolelinux to keep liking it?" I
+can list a few points about that:</p>
 
 <ul>
 
-<li>schools would like to get rid of proprietary software</li>
+ <li>always strive to get all things integrated into Debian upstream
+ <li>be open to discussion about changes and the like, even with newcomers
+ <li>be helpful at being helpful ;)
 
-<li>students will love the openness of the system, and will want to
-    experiment with it - maybe we need to harvest the native curiosity
-    of teenagers more?</li>
+</ul>
+
+<p>I'm really sorry I cannot say much more about that :(!</p>
 
-<li>there is no "right one" when it comes to strategies, but it would
-    be useful to have some success stories published somewhere, so
-    other can get some inspiration from them (I know I'd promote
-    them!)</li>
+<p><strong>Which free software do you use daily?</strong></p>
 
-<li>more active promotion - talks, conferences, even small school
-    lectures can do magical things if they encounter at least one
-    person interested. Who knows who that person might be? ;-)</li>
+<p>First of all, all software I use is free and open. I have abandoned
+all non-free software (except for firmware on my darned phone) this
+year.</p>
+
+<p>I run Debian GNU/Linux on all PC systems I use. On that, I mostly
+run text tools. I use
+<a href="https://www.mirbsd.org/mksh.htm">mksh</a> as shell,
+<a href="https://www.mirbsd.org/jupp.htm">jupp</a> as very advanced
+text editor (I even got the developer to help me write a script/macro
+based full-featured student management software with the two),
+<a href="http://mcabber.com/">mcabber</a> for XMPP and
+<a href="http://www.irssi.org/">irssi</a> for IRC. For that overly
+coloured world called the WWW, I use
+<a href="https://www.mozilla.org/en-US/firefox/new/">Iceweasel
+(Firefox)</a>. Oh, and <a href="http://www.mutt.org/">mutt</a> for
+e-mail.</p>
+
+<p>However, while I am personally aware of the fact that text tools
+are more efficient and powerful than anything else, I also use (or at
+least operate) some tools that are suitable to bring open source to
+kids. One of these things is <a href="http://jappix.org/">Jappix</a>,
+which I already introduced to some kids even before they got aware of
+Facebook, making them see for themselves that they do not need
+Facebook now ;).</p>
 
-</ul>
+<p><strong>Which strategy do you believe is the right one to use to
+get schools to use free software?</strong></p>
 
-<p>I also see some problems in getting Skolelinux into schools; for
-example, in our country we have a great deal of corruption issues, so
-it might be hard(er) to fight against proprietary solutions. Also,
-people who relied on commercial software for all their lives, would be
-very hard to convert against their will.</p>
+<p>Well, that's a two-sided thing. One side is what I believe, and one
+side is what I have experienced.</p>
+
+<p>I believe that the right strategy is showing them the benefits. But
+that won't work out as long as the acceptance of free alternatives
+grows globally. What I mean is that if all the kids are almost forced
+to use Windows, Facebook, Skype, you name it at home, they will not
+see why they would want to use alternatives at school. I have seen
+students take seat in front of a fully-functional, modern Debian
+desktop that could do anything their Windows at home could do, and
+they jsut refused to use it because "Linux sucks". It is something
+that makes the council of our city spend around 600000 € to buy
+software - not including hardware, mind you - for operating school
+networks, and for installing a system that, as has been proved, does
+not work. For those of you readers who are good at maths, have you
+already found out how many lives could have been saved with that money
+if we had instead used it to bring education to parts of the world
+that need it? I have, and found it to be nothing less dramatic than
+plain criminal.</p>
+
+<p>That said, the only feasible way appears to be the bottom up
+method. We have to bring free software to kids and parents. I have
+founded an association named
+<a href="https://www.teckids.org">Teckids</a> here in Germany that does
+just that. We organise several events for kids and adolescents in the
+area of free and open source software, for example the
+<a href="http://kids.froscon.org">FrogLabs</a>, which share staff with
+Teckids and are the youth programme of
+<a href="http://www.froscon.org">the Free and Open Source Software
+Conference (FrOSCon)</a>. We do a lot more than most other conferences
+- this year, we first offered the FrogLabs as a holiday camp for kids
+aged 10 to 16. It was a huge success, with approx. 30 kids taking part
+and learning with and about free software through a whole weekend. All
+of us had a lot of fun, and the results were really exciting.</p>
+
+<p>Apart from that, we are preparing a campaign that is supposed to bring
+the message of free alternatives to stuff kids use every day to them and
+their parents, e.g. the use of Jabber / Jappix instead of Facebook and
+Skype. To make that possible, we are planning to get together a team of
+clever kids who understand very well what their peers need and can bring
+it across to them. So we will have a peer-driven network of adolescents
+who teach each other and collect feedback from the community of minors.
+We then take that feedback and our own experience to work closely with
+open source projects, such as Skolelinux or Jappix, at improving their
+software in a way that makes it more and more attractive for the target
+group. At least I hope that we will have good cooperation with
+Skolelinux in the future ;)!</p>
+
+<p>So in conclusion, what I believe is that, if it weren't for the world
+being so bad, it should be very clear to the political decision makers
+that the only way to go nowadays is free software for various reasons,
+but I have learnt that the only way that seems to work is bottom up.</p>
+
+<!--
+
+>  * Who should be interviewed with this questions in the future?
+
+That's probably the hardest question of them all, as I do not know the
+community. However, I would be willing to do the following:
+
+ <li>Run an interview with a German headteacher who is very open to
+   free software, and also prefers it, but cannot really use it because
+   of the decision makers above;
+ <li>Run interviews with some kids, both with and without previous
+   knowledge about free software
+
+If that is wanted, just let me know ;).

-      <div class="date">12th June 2013</div>
-      <div class="body"><p>There is a certain cross-over between the
-<a href="http://www.skolelinux.org/">Debian Edu / Skolelinux
-project</a> and <a href="http://www.edubuntu.org/">the Edubuntu
-project</a>, and for example the LTSP packages in Debian are a joint
-effort between the projects.  One person with a foot in both camps is
-Jonathan Carter, which I am now happy to present to you.</p>
-
-<p><strong>Who are you, and how do you spend your days?</strong></p>
-
-<p>I'm a South-African free software geek who lives in Cape Town. My
-days vary quite a bit since I'm involved in too many things. As I'm
-getting older I'm learning how to focus a bit more :)</p>
-
-<p>I'm also an Edubuntu contributor and I love when there are
-opportunities for the Edubuntu and Debian Edu projects to benefit from
-each other.</p>
-
-<p><strong>How did you get in contact with the Skolelinux / Debian Edu
-project?</strong></p>
-
-<p>I've been somewhat familiar with the project before, but I think my
-first direct exposure to the project was when I met Petter
-[Reinholdtsen] and Knut [Yrvin] at the Edubuntu summit in 2005 in
-London. They provided great feedback that helped the bootstrapping of
-Edubuntu. Back then Edubuntu (and even Ubuntu) was still very new and
-it was great getting input from people who have been around longer. I
-was also still very excitable and said yes to everything and to this
-day I have a big todo list backlog that I'm catching up with. I think
-over the years the relationship between Edubuntu and Debian-Edu has
-been gradually improving, although I think there's a lot that we could
-still improve on in terms of working together on packages. I'm sure
-we'll get there one day.</p>
-
-<p><strong>What do you see as the advantages of Skolelinux / Debian
-Edu?</strong></p>
-
-<p>Debian itself already has so many advantages. I could go on about
-it for pages, but in essence I love that it's a very honest project
-that puts its users first with no hidden agendas and also produces
-very high quality work.</p>
-
-<p>I think the advantage of Debian Edu is that it makes many common
-set-up tasks simpler so that administrators can get up and running
-with a lot less effort and frustration. At the same time I think it
-helps to standardise installations in schools so that it's easier for
-community members and commercial suppliers to support.</p>
-
-<p><strong>What do you see as the disadvantages of Skolelinux / Debian
-Edu?</strong></p>
-
-<p>I had to re-type this one a few times because I'm trying to
-separate "disadvantages" from "areas that need improvement" (which is
-what I originally rambled on about)</p>
-
-<p>The biggest disadvantage I can think of is lack of manpower. The
-project could do so much more if there were more good contributors. I
-think some of the problems are external too. Free software and free
-content in education is a no-brainer but it takes some time to catch
-on. When you've been working with the same proprietary eco-system for
-years and have gotten used to it, it can be hard to adjust to some
-concepts in the free software world. It would be nice if there were
-more Debian Edu consultants across the world. I'd love to be one
-myself but I'm already so over-committed that it's just not possible
-currently.</p>
-
-<p>I think the best short-term solution to that large-scale problem is
-for schools to be pro-active and share their experiences and grow
-their skills in-house. I'm often saddened to see how much money
-educational institutions spend on 3rd party solutions that they don't
-have access to after the service has ended and they could've gotten so
-much more value otherwise by being more self-sustainable and
-autonomous.</p>
-
-<p><strong>Which free software do you use daily?</strong></p>
-
-<p>My main laptop dual-boots between Debian and Windows 7. I was
-Windows free for years but started dual-booting again last year for
-some games which help me focus and relax (Starcraft II in
-particular). Gaming support on Linux is improving in leaps and bounds
-so I suppose I'll soon be able to regain that disk space :)</p>
-
-<p>Besides that I rely on Icedove, Chromium, Terminator, Byobu, irssi,
-git, Tomboy, KVM, VLC and LibreOffice. Recently I've been torn on
-which desktop environment I like and I'm taking some refuge in Xfce
-while I figure that out. I like tools that keep things simple. I enjoy
-Python and shell scripting. I went to an Arduino workshop recently and
-it was awesome seeing how easy and simple the IDE software was to get
-up and running in Debian compared to the users running Windows and OS
-X.</p>
-
-<p>I also use mc which some people frown upon slightly. I got used to
-using Norton Commander in the early 90's and it stuck (I think the
-people who sneer at it is just jealous that they don't know how to use
-it :p)
-
-<p><strong>Which strategy do you believe is the right one to use to
-get schools to use free software?</strong></p>
-
-<p>I think trying to force it is unproductive. I also think that in
-many cases it's appropriate for schools to use non-free systems and I
-don't think that there's any particular moral or ethical problem with
-that.</p>
-
-<p>I do think though that free software can already solve so so many
-problems in educational institutions and it's just a shame not taking
-advantage of that.</p>
-
-<p>I also think that some curricula need serious review. For example,
-some areas of the world rely heavily on very specific versions of MS
-Office, teaching students to parrot menu items instead of learning the
-general concepts. I think that's very unproductive because firstly, MS
-Office's interface changes drastically every few years and on top of
-that it also locks in a generation to a product that might not be the
-best solution for them.</p>
-
-<p>To answer your question, I believe that the right strategy is to
-educate and inform, giving someone the information they require to
-make a decision that would work for them.</p>

+der vi hjelper folk som er interessert i å få opp sin egen mesh-node.
+Jeg gleder meg til å se hvordan prosjektet blir mottatt der.</p>
+
+<p>Målet med dugnadsnett for alle i Oslo er å få på plass et datanett
+for kommunikasjon ved hjelp av radio-repeaterstasjoner (kalt
+mesh-noder) som gjør at en kan direkte kommunisere med slekt, venner
+og bekjente i Oslo via andre som deltar i dugnadsnettet, samt gjøre
+det mulig komme ut på internett via dugnadsnettet.  Første delmål er å
+kunne sende SMS-meldinger vha. IP-telefoni løsningen
+<a href="http://www.servalproject.org/">Serval project</a> mellom
+deltagerne i Dugnadsnett for alle i Oslo.  Formålet er å ta tilbake
+kontrollen over egen nett-infrastruktur og gjøre det dyrere å bedrive
+massiv innsamling av informasjon om borgernes bruk av datanett.</p>
+
+<p>Høres dette interessant ut?  Bli med på prosjektet, fortell oss
+hvor du kunne tenke deg å sette opp en radio-repeater (slik at folk i
