-               <description>&lt;p&gt;Today NUUG and Hackeriet announced
-&lt;a href=&quot;http://www.nuug.no/news/Bli_med___bygge_dugnadsnett_for_alle_i_Oslo.shtml&quot;&gt;our
-plans to join forces and create a wireless community network in
-Oslo&lt;/a&gt;.  The workshop to help people get started will take place
-Thursday 2013-11-28, but we already are collecting the geolocation of
-people joining forces to make this happen.  We have
-&lt;a href=&quot;https://github.com/petterreinholdtsen/meshfx-node/blob/master/oslo-nodes.geojson&quot;&gt;9
-locations plotted on the map&lt;/a&gt;, but we will need more before we have
-a connected mesh spread across Oslo.  If this sound interesting to
-you, please join us at the workshop.  If you are too impatient to wait
-15 days, please join us on the IRC channel
-&lt;a href=&quot;irc://irc.freenode.net/%23nuug&quot;&gt;#nuug on irc.freenode.net&lt;/a&gt;
-right away. :)&lt;/p&gt;

-               <description>&lt;p&gt;Continuing my research into mesh networking, I was recommended to
-use TP-Link 3040 and 3600 access points as mesh nodes, and the pair I
-bought arrived on Friday.  Here are my notes on how to set up the
-MR3040 as a mesh node using
-&lt;a href=&quot;http://www.openwrt.org/&quot;&gt;OpenWrt&lt;/a&gt;.&lt;/p&gt;
-
-&lt;p&gt;I started by following the instructions on the OpenWRT wiki for
-&lt;a href=&quot;http://wiki.openwrt.org/toh/tp-link/tl-mr3040&quot;&gt;TL-MR3040&lt;/a&gt;,
-and downloaded
-&lt;a href=&quot;http://downloads.openwrt.org/snapshots/trunk/ar71xx/openwrt-ar71xx-generic-tl-mr3040-v2-squashfs-factory.bin&quot;&gt;the
-recommended firmware image&lt;/a&gt;
-(openwrt-ar71xx-generic-tl-mr3040-v2-squashfs-factory.bin) and
-uploaded it into the original web interface.  The flashing went fine,
-and the machine was available via telnet on the ethernet port.  After
-logging in and setting the root password, ssh was available and I
-could start to set it up as a batman-adv mesh node.&lt;/p&gt;
-
-&lt;p&gt;I started off by reading the instructions from
-&lt;a href=&quot;http://wirelessafrica.meraka.org.za/wiki/index.php?title=Antoine&#39;s_Research&quot;&gt;Wireless
-Africa&lt;/a&gt;, which had quite a lot of useful information, but
-eventually I followed the recipe from the Open Mesh wiki for
-&lt;a href=&quot;http://www.open-mesh.org/projects/batman-adv/wiki/Batman-adv-openwrt-config&quot;&gt;using
-batman-adv on OpenWrt&lt;/a&gt;.  A small snag was the fact that the
-&lt;tt&gt;opkg install kmod-batman-adv&lt;/tt&gt; command did not work as it
-should.  The batman-adv kernel module would fail to load because its
-dependency crc16 was not already loaded.  I
-&lt;a href=&quot;https://dev.openwrt.org/ticket/14452&quot;&gt;reported the bug&lt;/a&gt; to
-the openwrt project and hope it will be fixed soon.  But the problem
-only seem to affect initial testing of batman-adv, as configuration
-seem to work when booting from scratch.&lt;/p&gt;
-
-&lt;p&gt;The setup is done using files in /etc/config/.  I did not bridge
-the Ethernet and mesh interfaces this time, to be able to hook up the
-box on my local network and log into it for configuration updates.
-The following files were changed and look like this after modifying
-them:&lt;/p&gt;

+               <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Spr_kkoder_for_POSIX_locale_i_Norge.html</guid>
+                <pubDate>Fri, 11 Apr 2014 21:30:00 +0200</pubDate>
+               <description>&lt;p&gt;For 12 år siden, skrev jeg et lite notat om
+&lt;a href=&quot;http://i18n.skolelinux.no/localekoder.txt&quot;&gt;bruk av språkkoder
+i Norge&lt;/a&gt;.  Jeg ble nettopp minnet på dette da jeg fikk spørsmål om
+notatet fortsatt var aktuelt, og tenkte det var greit å repetere hva
+som fortsatt gjelder.  Det jeg skrev da er fortsatt like aktuelt.&lt;/p&gt;
+
+&lt;p&gt;Når en velger språk i programmer på unix, så velger en blant mange
+språkkoder.  For språk i Norge anbefales følgende språkkoder (anbefalt
+locale i parantes):&lt;/p&gt;
+
+&lt;p&gt;&lt;dl&gt;
+&lt;dt&gt;nb (nb_NO)&lt;/dt&gt;&lt;dd&gt;Bokmål i Norge&lt;/dd&gt;
+&lt;dt&gt;nn (nn_NO)&lt;/dt&gt;&lt;dd&gt;Nynorsk i Norge&lt;/dd&gt;
+&lt;dt&gt;se (se_NO)&lt;/dt&gt;&lt;dd&gt;Nordsamisk i Norge&lt;/dd&gt;
+&lt;/dl&gt;&lt;/p&gt;
+
+&lt;p&gt;Alle programmer som bruker andre koder bør endres.&lt;/p&gt;
+
+&lt;p&gt;Språkkoden bør brukes når .po-filer navngis og installeres.  Dette
+er ikke det samme som locale-koden.  For Norsk Bokmål, så bør filene
+være navngitt nb.po, mens locale (LANG) bør være nb_NO.&lt;/p&gt;
+
+&lt;p&gt;Hvis vi ikke får standardisert de kodene i alle programmene med
+norske oversettelser, så er det umulig å gi LANG-variablen ett innhold
+som fungerer for alle programmer.&lt;/p&gt;
+
+&lt;p&gt;Språkkodene er de offisielle kodene fra ISO 639, og bruken av dem i
+forbindelse med POSIX localer er standardisert i RFC 3066 og ISO
+15897.  Denne anbefalingen er i tråd med de angitte standardene.&lt;/p&gt;
+
+&lt;p&gt;Følgende koder er eller har vært i bruk som locale-verdier for
+&quot;norske&quot; språk.  Disse bør unngås, og erstattes når de oppdages:&lt;/p&gt;

+&lt;tr&gt;&lt;td&gt;sme_NO   &lt;/td&gt;&lt;td&gt;-&gt; se_NO&lt;/td&gt;&lt;/tr&gt;

-&lt;p&gt;The mesh node is now operational.  I have yet to test its range,

+&lt;p&gt;Merk at når det gjelder de samiske språkene, at se_NO i praksis
+henviser til nordsamisk i Norge, mens f.eks.  smj_NO henviser til
+lulesamisk.  Dette notatet er dog ikke ment å gi råd rundt samiske

-               <description>&lt;p&gt;If one of the points of switching to a new init system in Debian is
-&lt;a href=&quot;http://thomas.goirand.fr/blog/?p=147&quot;&gt;to get rid of huge
-init.d scripts&lt;/a&gt;, I doubt we need to switch away from sysvinit and
-init.d scripts at all.  Here is an example init.d script, ie a rewrite
-of /etc/init.d/rsyslog:&lt;/p&gt;
-
-&lt;p&gt;&lt;pre&gt;
-#!/lib/init/init-d-script
-### BEGIN INIT INFO
-# Provides:          rsyslog
-# Required-Start:    $remote_fs $time
-# Required-Stop:     umountnfs $time
-# X-Stop-After:      sendsigs
-# Default-Start:     2 3 4 5
-# Default-Stop:      0 1 6
-# Short-Description: enhanced syslogd
-# Description:       Rsyslog is an enhanced multi-threaded syslogd.
-#                    It is quite compatible to stock sysklogd and can be 
-#                    used as a drop-in replacement.
-### END INIT INFO
-DESC=&quot;enhanced syslogd&quot;
-DAEMON=/usr/sbin/rsyslogd
-&lt;/pre&gt;&lt;/p&gt;
-
-&lt;p&gt;Pretty minimalistic to me... For the record, the original sysv-rc
-script was 137 lines, and the above is just 15 lines, most of it meta
-info/comments.&lt;/p&gt;
-
-&lt;p&gt;How to do this, you ask?  Well, one create a new script
-/lib/init/init-d-script looking something like this:
-
-&lt;p&gt;&lt;pre&gt;
-#!/bin/sh
-
-# Define LSB log_* functions.
-# Depend on lsb-base (&gt;= 3.2-14) to ensure that this file is present
-# and status_of_proc is working.

+                <pubDate>Wed, 9 Apr 2014 11:30:00 +0200</pubDate>
+               <description>&lt;p&gt;For a while now, I have been looking for a sensible offsite backup
+solution for use at home.  My requirements are simple, it must be
+cheap and locally encrypted (in other words, I keep the encryption
+keys, the storage provider do not have access to my private files).
+One idea me and my friends had many years ago, before the cloud
+storage providers showed up, was to use Google mail as storage,
+writing a Linux block device storing blocks as emails in the mail
+service provided by Google, and thus get heaps of free space.  On top
+of this one can add encryption, RAID and volume management to have
+lots of (fairly slow, I admit that) cheap and encrypted storage.  But
+I never found time to implement such system.  But the last few weeks I
+have looked at a system called
+&lt;a href=&quot;https://bitbucket.org/nikratio/s3ql/&quot;&gt;S3QL&lt;/a&gt;, a locally
+mounted network backed file system with the features I need.&lt;/p&gt;
+
+&lt;p&gt;S3QL is a fuse file system with a local cache and cloud storage,
+handling several different storage providers, any with Amazon S3,
+Google Drive or OpenStack API.  There are heaps of such storage
+providers.  S3QL can also use a local directory as storage, which
+combined with sshfs allow for file storage on any ssh server.  S3QL
+include support for encryption, compression, de-duplication, snapshots
+and immutable file systems, allowing me to mount the remote storage as
+a local mount point, look at and use the files as if they were local,
+while the content is stored in the cloud as well.  This allow me to
+have a backup that should survive fire.  The file system can not be
+shared between several machines at the same time, as only one can
+mount it at the time, but any machine with the encryption key and
+access to the storage service can mount it if it is unmounted.&lt;/p&gt;
+
+&lt;p&gt;It is simple to use.  I&#39;m using it on Debian Wheezy, where the
+package is included already.  So to get started, run &lt;tt&gt;apt-get
+install s3ql&lt;/tt&gt;.  Next, pick a storage provider.  I ended up picking
+Greenqloud, after reading their nice recipe on
+&lt;a href=&quot;https://greenqloud.zendesk.com/entries/44611757-How-To-Use-S3QL-to-mount-a-StorageQloud-bucket-on-Debian-Wheezy&quot;&gt;how
+to use S3QL with their Amazon S3 service&lt;/a&gt;, because I trust the laws
+in Iceland more than those in USA when it come to keeping my personal
+data safe and private, and thus would rather spend money on a company
+in Iceland.  Another nice recipe is available from the article
+&lt;a href=&quot;http://www.admin-magazine.com/HPC/Articles/HPC-Cloud-Storage&quot;&gt;S3QL
+Filesystem for HPC Storage&lt;/a&gt; by Jeff Layton in the HPC section of
+Admin magazine.  When the provider is picked, figure out how to get
+the API key needed to connect to the storage API.  With Greencloud,
+the key did not show up until I had added payment details to my
+account.&lt;/p&gt;
+
+&lt;p&gt;Armed with the API access details, it is time to create the file
+system.  First, create a new bucket in the cloud.  This bucket is the
+file system storage area.  I picked a bucket name reflecting the
+machine that was going to store data there, but any name will do.
+I&#39;ll refer to it as &lt;tt&gt;bucket-name&lt;/tt&gt; below.  In addition, one need
+the API login and password, and a locally created password.  Store it
+all in ~root/.s3ql/authinfo2 like this:
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+[s3c]
+storage-url: s3c://s.greenqloud.com:443/bucket-name
+backend-login: API-login
+backend-password: API-password
+fs-passphrase: local-password
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;I create my local passphrase using &lt;tt&gt;pwget 50&lt;/tt&gt; or similar,
+but any sensible way to create a fairly random password should do it.
+Armed with these details, it is now time to run mkfs, entering the API
+details and password to create it:&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;

+
+&lt;p&gt;The file system is now ready for use.  I use rsync to store my
+backups in it, and as the metadata used by rsync is downloaded at
+mount time, no network traffic (and storage cost) is triggered by
+running rsync.  To unmount, one should not use the normal umount
+command, as this will not flush the cache to the cloud storage, but
+instead running the umount.s3ql command like this:
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+# umount.s3ql /s3ql
+# 
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;There is a fsck command available to check the file system and
+correct any problems detected.  This can be used if the local server
+crashes while the file system is mounted, to reset the &quot;already
+mounted&quot; flag.  This is what it look like when processing a working
+file system:&lt;/p&gt;

+
+&lt;p&gt;Thanks to the cache, working on files that fit in the cache is very
+quick, about the same speed as local file access.  Uploading large
+amount of data is to me limited by the bandwidth out of and into my
+house.  Uploading 685 MiB with a 100 MiB cache gave me 305 kiB/s,
+which is very close to my upload speed, and downloading the same
+Debian installation ISO gave me 610 kiB/s, close to my download speed.
+Both were measured using &lt;tt&gt;dd&lt;/tt&gt;.  So for me, the bottleneck is my
+network, not the file system code.  I do not know what a good cache
+size would be, but suspect that the cache should e larger than your
+working set.&lt;/p&gt;
+
+&lt;p&gt;I mentioned that only one machine can mount the file system at the
+time.  If another machine try, it is told that the file system is
+busy:&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;

+&lt;p&gt;The file content is uploaded when the cache is full, while the
+metadata is uploaded once every 24 hour by default.  To ensure the
+file system content is flushed to the cloud, one can either umount the
+file system, or ask S3QL to flush the cache and metadata using
+s3qlctrl:
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;

+&lt;p&gt;If you are curious about how much space your data uses in the

+storage usage, you can use s3qlstat on the mounted file system to get
+a report:&lt;/p&gt;

-&lt;p&gt;It is based on /etc/init.d/skeleton, and could be improved quite a
-lot.  I did not really polish the approach, so it might not always
-work out of the box, but you get the idea.  I did not try very hard to
-optimize it nor make it more robust either.&lt;/p&gt;
-
-&lt;p&gt;A better argument for switching init system in Debian than reducing
-the size of init scripts (which is a good thing to do anyway), is to
-get boot system that is able to handle the kernel events sensibly and
-robustly, and do not depend on the boot to run sequentially.  The boot
-and the kernel have not behaved sequentially in years.&lt;/p&gt;
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;I mentioned earlier that there are several possible suppliers of
+storage.  I did not try to locate them all, but am aware of at least
+&lt;a href=&quot;https://www.greenqloud.com/&quot;&gt;Greenqloud&lt;/a&gt;,
+&lt;a href=&quot;http://drive.google.com/&quot;&gt;Google Drive&lt;/a&gt;,
+&lt;a href=&quot;http://aws.amazon.com/s3/&quot;&gt;Amazon S3 web serivces&lt;/a&gt;,
+&lt;a href=&quot;http://www.rackspace.com/&quot;&gt;Rackspace&lt;/a&gt; and
+&lt;a href=&quot;http://crowncloud.net/&quot;&gt;Crowncloud&lt;/A&gt;.  The latter even
+accept payment in Bitcoin.  Pick one that suit your need.  Some of
+them provide several GiB of free storage, but the prize models are
+quite different and you will have to figure out what suits you
+best.&lt;/p&gt;
+
+&lt;p&gt;While researching this blog post, I had a look at research papers
+and posters discussing the S3QL file system.  There are several, which
+told me that the file system is getting a critical check by the
+science community and increased my confidence in using it.  One nice
+poster is titled
+&quot;&lt;a href=&quot;http://www.lanl.gov/orgs/adtsc/publications/science_highlights_2013/docs/pg68_69.pdf&quot;&gt;An
+Innovative Parallel Cloud Storage System using OpenStack’s SwiftObject
+Store and Transformative Parallel I/O Approach&lt;/a&gt;&quot; by Hsing-Bung
+Chen, Benjamin McClelland, David Sherrill, Alfred Torrez, Parks Fields
+and Pamela Smith.  Please  have a look.&lt;/p&gt;
+
+&lt;p&gt;Given my problems with different file systems earlier, I decided to
+check out the mounted S3QL file system to see if it would be usable as
+a home directory (in other word, that it provided POSIX semantics when
+it come to locking and umask handling etc).  Running
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Testing_if_a_file_system_can_be_used_for_home_directories___.html&quot;&gt;my
+test code to check file system semantics&lt;/a&gt;, I was happy to discover that
+no error was found.  So the file system can be used for home
+directories, if one chooses to do so.&lt;/p&gt;
+
+&lt;p&gt;If you do not want a locally file system, and want something that
+work without the Linux fuse file system, I would like to mention the
+&lt;a href=&quot;http://www.tarsnap.com/&quot;&gt;Tarsnap service&lt;/a&gt;, which also
+provide locally encrypted backup using a command line client.  It have
+a nicer access control system, where one can split out read and write
+access, allowing some systems to write to the backup and others to
+only read from it.&lt;/p&gt;
+
+&lt;p&gt;As usual, if you use Bitcoin and want to show your support of my
+activities, please send Bitcoin donations to my address
+&lt;b&gt;&lt;a href=&quot;bitcoin:15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&amp;label=PetterReinholdtsenBlog&quot;&gt;15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&lt;/a&gt;&lt;/b&gt;.&lt;/p&gt;

-remote display access is the preferred solution with oVirt and RedHat
-Enterprise Virtualization, and I was sad to discover the other day
-that the browser plugin needed to use these systems seamlessly was
-missing in Debian.  The &lt;a href=&quot;http://bugs.debian.org/668284&quot;&gt;request
-for a package&lt;/a&gt; was from 2012-04-10 with no progress since
-2013-04-01, so I decided to wrap up a package based on the great work
-from Cajus Pollmeier and put it in a collab-maint maintained git
-repository to get a package I could use.  I would very much like
-others to help me maintain the package (or just take over, I do not
-mind), but as no-one had volunteered so far, I just uploaded it to
-NEW.  I hope it will be available in Debian in a few days.&lt;/p&gt;

+&lt;p&gt;Jeg synes det er veldig fint at nok en stemme slår fast at
+totalitær overvåkning av befolkningen er uakseptabelt, men det er
+fortsatt like viktig å beskytte privatsfæren som før, da de
+teknologiske mulighetene fortsatt finnes og utnyttes, og jeg tror
+innsats i prosjekter som
+&lt;a href=&quot;https://wiki.debian.org/FreedomBox&quot;&gt;Freedombox&lt;/a&gt; og
+&lt;a href=&quot;http://www.dugnadsnett.no/&quot;&gt;Dugnadsnett&lt;/a&gt; er viktigere enn
+noen gang.&lt;/p&gt;
+
+&lt;p&gt;&lt;strong&gt;Update 2014-04-08 12:10&lt;/strong&gt;: Kronerullingen for å
+stoppe datalagringsdirektivet i Norge gjøres hos foreningen
+&lt;a href=&quot;http://www.digitaltpersonvern.no/&quot;&gt;Digitalt Personvern&lt;/a&gt;,
+som har samlet inn 843 215,- så langt men trenger nok mye mer hvis
+
+ikke Høyre og Arbeiderpartiet bytter mening i saken.  Det var
+&lt;a href=&quot;http://www.holderdeord.no/parliament-issues/48650&quot;&gt;kun
+partinene Høyre og Arbeiderpartiet&lt;/a&gt; som stemte for
+Datalagringsdirektivet, og en av dem må bytte mening for at det skal
+bli flertall mot i Stortinget.  Se mer om saken

-                <pubDate>Sun, 27 Oct 2013 17:00:00 +0100</pubDate>
-               <description>&lt;p&gt;The
-&lt;a href=&quot;http://packages.qa.debian.org/v/vmdebootstrap.html&quot;&gt;vmdebootstrap&lt;/a&gt;
-program is a a very nice system to create virtual machine images.  It
-create a image file, add a partition table, mount it and run
-debootstrap in the mounted directory to create a Debian system on a
-stick.  Yesterday, I decided to try to teach it how to make images for
-&lt;a href=&quot;https://wiki.debian.org/RaspberryPi&quot;&gt;Raspberry Pi&lt;/a&gt;, as part
-of a plan to simplify the build system for
-&lt;a href=&quot;https://wiki.debian.org/FreedomBox&quot;&gt;the FreedomBox
-project&lt;/a&gt;.  The FreedomBox project already uses vmdebootstrap for
-the virtualbox images, but its current build system made multistrap
-based system for Dreamplug images, and it is lacking support for
-Raspberry Pi.&lt;/p&gt;
-
-&lt;p&gt;Armed with the knowledge on how to build &quot;foreign&quot; (aka non-native
-architecture) chroots for Raspberry Pi, I dived into the vmdebootstrap
-code and adjusted it to be able to build armel images on my amd64
-Debian laptop.  I ended up giving vmdebootstrap five new options,
-allowing me to replicate the image creation process I use to make
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/A_Raspberry_Pi_based_batman_adv_Mesh_network_node.html&quot;&gt;Debian
-Jessie based mesh node images for the Raspberry Pi&lt;/a&gt;.  First, the
-&lt;tt&gt;--foreign /path/to/binfm_handler&lt;/tt&gt; option tell vmdebootstrap to
-call debootstrap with --foreign and to copy the handler into the
-generated chroot before running the second stage.  This allow
-vmdebootstrap to create armel images on an amd64 host.  Next I added
-two new options &lt;tt&gt;--bootsize size&lt;/tt&gt; and &lt;tt&gt;--boottype
-fstype&lt;/tt&gt; to teach it to create a separate /boot/ partition with the
-given file system type, allowing me to create an image with a vfat
-partition for the /boot/ stuff.  I also added a &lt;tt&gt;--variant
-variant&lt;/tt&gt; option to allow me to create smaller images without the
-Debian base system packages installed.  Finally, I added an option
-&lt;tt&gt;--no-extlinux&lt;/tt&gt; to tell vmdebootstrap to not install extlinux
-as a boot loader.  It is not needed on the Raspberry Pi and probably
-most other non-x86 architectures.  The changes were accepted by the
-upstream author of vmdebootstrap yesterday and today, and is now
-available from
-&lt;a href=&quot;http://git.liw.fi/cgi-bin/cgit/cgit.cgi/vmdebootstrap/&quot;&gt;the
-upstream project page&lt;/a&gt;.&lt;/p&gt;
-
-&lt;p&gt;To use it to build a Raspberry Pi image using Debian Jessie, first
-create a small script (the customize script) to add the non-free
-binary blob needed to boot the Raspberry Pi and the APT source
-list:&lt;/p&gt;
-
-&lt;p&gt;&lt;pre&gt;
-#!/bin/sh
-set -e # Exit on first error
-rootdir=&quot;$1&quot;
-cd &quot;$rootdir&quot;
-cat &amp;lt;&amp;lt;EOF &gt; etc/apt/sources.list
-deb http://http.debian.net/debian/ jessie main contrib non-free
-EOF
-# Install non-free binary blob needed to boot Raspberry Pi.  This
-# install a kernel somewhere too.
-wget https://raw.github.com/Hexxeh/rpi-update/master/rpi-update \
-    -O $rootdir/usr/bin/rpi-update
-chmod a+x $rootdir/usr/bin/rpi-update
-mkdir -p $rootdir/lib/modules
-touch $rootdir/boot/start.elf
-chroot $rootdir rpi-update
-&lt;/pre&gt;&lt;/p&gt;
-
-&lt;p&gt;Next, fetch the latest vmdebootstrap script and call it like this
-to build the image:&lt;/p&gt;
-
-&lt;pre&gt;
-sudo ./vmdebootstrap \
-    --variant minbase \
-    --arch armel \
-    --distribution jessie \
-    --mirror http://http.debian.net/debian \
-    --image test.img \
-    --size 600M \
-    --bootsize 64M \
-    --boottype vfat \
-    --log-level debug \
-    --verbose \
-    --no-kernel \
-    --no-extlinux \
-    --root-password raspberry \
-    --hostname raspberrypi \
-    --foreign /usr/bin/qemu-arm-static \
-    --customize `pwd`/customize \
-    --package netbase \
-    --package git-core \
-    --package binutils \
-    --package ca-certificates \
-    --package wget \
-    --package kmod
-&lt;/pre&gt;&lt;/p&gt;
-
-&lt;p&gt;The list of packages being installed are the ones needed by
-rpi-update to make the image bootable on the Raspberry Pi, with the
-exception of netbase, which is needed by debootstrap to find
-/etc/hosts with the minbase variant.  I really wish there was a way to
-set up an Raspberry Pi using only packages in the Debian archive, but
-that is not possible as far as I know, because it boots from the GPU
-using a non-free binary blob.&lt;/p&gt;
-
-&lt;p&gt;The build host need debootstrap, kpartx and qemu-user-static and
-probably a few others installed.  I have not checked the complete
-build dependency list.&lt;/p&gt;
-
-&lt;p&gt;The resulting image will not use the hardware floating point unit
-on the Raspberry PI, because the armel architecture in Debian is not
-optimized for that use.  So the images created will be a bit slower
-than &lt;a href=&quot;http://www.raspbian.org/&quot;&gt;Raspbian&lt;/a&gt; based images.&lt;/p&gt;

+               <description>&lt;p&gt;Microsoft have announced that Windows XP reaches its end of life
+2014-04-08, in 7 days.  But there are heaps of machines still running
+Windows XP, and depending on Windows XP to run their applications, and
+upgrading will be expensive, both when it comes to money and when it
+comes to the amount of effort needed to migrate from Windows XP to a
+new operating system.  Some obvious options (buy new a Windows
+machine, buy a MacOSX machine, install Linux on the existing machine)
+are already well known and covered elsewhere.  Most of them involve
+leaving the user applications installed on Windows XP behind and
+trying out replacements or updated versions. In this blog post I want
+to mention one strange bird that allow people to keep the hardware and
+the existing Windows XP applications and run them on a free software
+operating system that is Windows XP compatible.&lt;/p&gt;
+
+&lt;p&gt;&lt;a href=&quot;http://www.reactos.org/&quot;&gt;ReactOS&lt;/a&gt; is a free software
+operating system (GNU GPL licensed) working on providing a operating
+system that is binary compatible with Windows, able to run windows
+programs directly and to use Windows drivers for hardware directly.
+The project goal is for Windows user to keep their existing machines,
+drivers and software, and gain the advantages from user a operating
+system without usage limitations caused by non-free licensing.  It is
+a Windows clone running directly on the hardware, so quite different
+from the approach taken by &lt;a href=&quot;http://www.winehq.org/&quot;&gt;the Wine
+project&lt;/a&gt;, which make it possible to run Windows binaries on
+Linux.&lt;/p&gt;
+
+&lt;p&gt;The ReactOS project share code with the Wine project, so most
+shared libraries available on Windows are already implemented already.
+There is also a software manager like the one we are used to on Linux,
+allowing the user to install free software applications with a simple
+click directly from the Internet.  Check out the
+&lt;a href=&quot;http://www.reactos.org/screenshots&quot;&gt;screen shots on the
+project web site&lt;/a&gt; for an idea what it look like (it looks just like
+Windows before metro).&lt;/p&gt;
+
+&lt;p&gt;I do not use ReactOS myself, preferring Linux and Unix like
+operating systems.  I&#39;ve tested it, and it work fine in a virt-manager
+virtual machine.  The browser, minesweeper, notepad etc is working
+fine as far as I can tell.  Unfortunately, my main test application
+is the software included on a CD with the Lego Mindstorms NXT, which
+seem to install just fine from CD but fail to leave any binaries on
+the disk after the installation.  So no luck with that test software.
+No idea why, but hope someone else figure out and fix the problem.
+I&#39;ve tried the ReactOS Live ISO on a physical machine, and it seemed
+to work just fine.  If you like Windows and want to keep running your
+old Windows binaries, check it out by
+&lt;a href=&quot;http://www.reactos.org/download&quot;&gt;downloading&lt;/a&gt; the
+installation CD, the live CD or the preinstalled virtual machine
+image.&lt;/p&gt;

-               <description>&lt;p&gt;De siste måneders eksponering av
-&lt;a href=&quot;http://www.aftenposten.no/nyheter/uriks/Her-er-Edvard-Snowdens-mest-omtalte-avsloringer-7351734.html&quot;&gt;den
-totale overvåkningen som foregår i den vestlige verden dokumenterer
-hvor sårbare vi er&lt;/a&gt;.  Men det slår meg at de som er mest sårbare
-for dette, myndighetspersoner på alle nivåer, neppe har innsett at de
-selv er de mest interessante personene å lage profiler på, for å kunne
-påvirke dem.&lt;/p&gt;
-
-&lt;p&gt;For å ta et lite eksempel: Stortingets nettsted,
-&lt;a href=&quot;http://www.stortinget.no/&quot;&gt;www.stortinget.no&lt;/a&gt; (og
-forsåvidt også
-&lt;a href=&quot;http://data.stortinget.no/&quot;&gt;data.stortinget.no&lt;/a&gt;),
-inneholder informasjon om det som foregår på Stortinget, og jeg antar
-de største brukerne av informasjonen der er representanter og
-rådgivere på Stortinget.  Intet overraskende med det.  Det som derimot
-er mer skjult er at Stortingets nettsted bruker
-&lt;a href=&quot;http://en.wikipedia.org/wiki/Google_Analytics&quot;&gt;Google
-Analytics&lt;/a&gt;, hvilket gjør at enhver som besøker nettsidene der også
-rapporterer om besøket via Internett-linjer som passerer Sverige,
-England og videre til USA.  Det betyr at informasjon om ethvert besøk
-på stortingets nettsider kan snappes opp av svensk, britisk og USAs
-etterretningsvesen.  De kan dermed holde et øye med hvilke
-Stortingssaker stortingsrepresentantene synes er interessante å sjekke
-ut, og hvilke sider rådgivere og andre på stortinget synes er
-interessant å besøke, når de gjør det og hvilke andre representanter
-som sjekker de samme sidene omtrent samtidig.  Stortingets bruk av
-Google Analytics gjør det dermed enkelt for utenlands etteretning å
-spore representantenes aktivitet og interesse.  Hvis noen av
-representantene bruker Google Mail eller noen andre tjenestene som
-krever innlogging, så vil det være enda enklere å finne ut nøyaktig
-hvilke personer som bruker hvilke nettlesere og dermed knytte
-informasjonen opp til enkeltpersoner på Stortinget.&lt;/p&gt;
-
-&lt;p&gt;Og jo flere nettsteder som bruker Google Analytics, jo bedre
-oversikt over stortingsrepresentantenes lesevaner og interesse blir
-tilgjengelig for svensk, britisk og USAs etterretning.  Hva de kan
-bruke den informasjonen til overlater jeg til leseren å undres
-over.&lt;/p&gt;

+               <description>&lt;p&gt;&lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu / Skolelinux&lt;/a&gt;
+keep gaining new users.  Some weeks ago, a person showed up on IRC,
+&lt;a href=&quot;irc://irc.debian.org/#debian-edu&quot;&gt;#debian-edu&lt;/a&gt;, with a
+wish to contribute, and I managed to get a interview with this great
+contributor Roger Marsal to learn more about his background.&lt;/p&gt;
+
+&lt;p&gt;&lt;strong&gt;Who are you, and how do you spend your days?&lt;/strong&gt;&lt;/p&gt;
+
+&lt;p&gt;My name is Roger Marsal, I&#39;m 27 years old (1986 generation) and I
+live in Barcelona, Spain. I&#39;ve got a strong business background and I
+work as a patrimony manager and as a real estate agent.  Additionally,
+I&#39;ve co-founded a British based tech company that is nowadays on the
+last development phase of a new social networking concept.&lt;/p&gt;
+
+&lt;p&gt;I&#39;m a Linux enthusiast that started its journey with Ubuntu four years
+ago and have recently switched to Debian seeking rock solid stability
+and as a necessary step to gain expertise.&lt;/p&gt;
+
+&lt;p&gt;In a nutshell, I spend my days working and learning as much as I
+can to face both my job, entrepreneur project and feed my Linux
+hunger.&lt;/p&gt;
+
+&lt;p&gt;&lt;strong&gt;How did you get in contact with the Skolelinux / Debian Edu
+project?&lt;/strong&gt;&lt;/p&gt;
+
+&lt;p&gt;I discovered the &lt;a href=&quot;http://www.ltsp.org/&quot;&gt;LTSP&lt;/a&gt; advantages
+with &quot;Ubuntu 12.04 alternate install&quot; and after a year of use I
+started looking for an alternative.  Even though I highly value and
+respect the Ubuntu project, I thought it was necessary for me to
+change to a more robust and stable alternative.  As far as I was using
+Debian on my personal laptop I thought it would be fine to install
+Debian and configure an LTSP server myself.  Surprised, I discovered
+that the Debian project also supported a kind of Edubuntu equivalent,
+and after having some pain I obtained a Debian Edu network up and
+running.  I just loved it.&lt;/p&gt;
+
+&lt;p&gt;&lt;strong&gt;What do you see as the advantages of Skolelinux / Debian
+Edu?&lt;/strong&gt;&lt;/p&gt;
+
+&lt;p&gt;I found a main advantage in that, once you know &quot;the tips and
+tricks&quot;, a new installation just works out of the box. It&#39;s the most
+complete alternative I&#39;ve found to create an LTSP network. All the
+other distributions seems to be made of plastic, Debian Edu seems to
+be made of steel.&lt;/p&gt;
+
+&lt;p&gt;&lt;strong&gt;What do you see as the disadvantages of Skolelinux / Debian
+Edu?&lt;/strong&gt;&lt;/p&gt;
+
+&lt;p&gt;I found two main disadvantages.&lt;/p&gt;
+
+&lt;p&gt;I&#39;m not an expert but I&#39;ve got notions and I had to spent a considerable
+amount of time trying to bring up a standard network topology. I&#39;m quite
+stubborn and I just worked until I did but I&#39;m sure many people with few
+resources (not big schools, but academies for example) would have switched
+or dropped.&lt;/p&gt;
+
+&lt;p&gt;It&#39;s amazing how such a complex system like Debian Edu has achieved
+this out-of-the-box state. Even though tweaking without breaking gets
+more difficult, as more factors have to be considered. This can
+discourage many people too.&lt;/p&gt;
+
+&lt;p&gt;&lt;strong&gt;Which free software do you use daily?&lt;/strong&gt;&lt;/p&gt;
+
+&lt;p&gt;I use Debian, Firefox, Okular, Inkscape, LibreOffice and
+Virtualbox.&lt;/p&gt;
+
+
+&lt;p&gt;&lt;strong&gt;Which strategy do you believe is the right one to use to
+get schools to use free software?&lt;/strong&gt;&lt;/p&gt;
+
+&lt;p&gt;I don&#39;t think there is a need for a particular strategy. The free
+attribute in both &quot;freedom&quot; and &quot;no price&quot; meanings is what will
+really bring free software to schools. In my experience I can think of
+the &lt;a href=&quot;http://www.r-project.org/&quot;&gt;&quot;R&quot; statistical language&lt;/a&gt;; a
+few years a ago was an extremely nerd tool for university people.
+Today it&#39;s being increasingly used to teach statistics at many
+different level of studies.  I believe free and open software will
+increasingly gain popularity, but I&#39;m sure schools will be one of the
+first scenarios where this will happen.&lt;/p&gt;

-               <title>A Raspberry Pi based batman-adv Mesh network node</title>
-               <link>http://people.skolelinux.org/pere/blog/A_Raspberry_Pi_based_batman_adv_Mesh_network_node.html</link>
-               <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/A_Raspberry_Pi_based_batman_adv_Mesh_network_node.html</guid>
-                <pubDate>Mon, 21 Oct 2013 11:40:00 +0200</pubDate>
-               <description>&lt;p&gt;The last few days I have been experimenting with
-&lt;a href=&quot;http://www.open-mesh.org/projects/batman-adv/wiki&quot;&gt;the
-batman-adv mesh technology&lt;/a&gt;.  I want to gain some experience to see
-if it will fit &lt;a href=&quot;https://wiki.debian.org/FreedomBox&quot;&gt;the
-Freedombox project&lt;/a&gt;, and together with my neighbors try to build a
-mesh network around the park where I live.  Batman-adv is a layer 2
-mesh system (&quot;ethernet&quot; in other words), where the mesh network appear
-as if all the mesh clients are connected to the same switch.&lt;/p&gt;
-
-&lt;p&gt;My hardware of choice was the Linksys WRT54GL routers I had lying
-around, but I&#39;ve been unable to get them working with batman-adv.  So
-instead, I started playing with a
-&lt;a href=&quot;http://www.raspberrypi.org/&quot;&gt;Raspberry Pi&lt;/a&gt;, and tried to
-get it working as a mesh node.  My idea is to use it to create a mesh
-node which function as a switch port, where everything connected to
-the Raspberry Pi ethernet plug is connected (bridged) to the mesh
-network.  This allow me to hook a wifi base station like the Linksys
-WRT54GL to the mesh by plugging it into a Raspberry Pi, and allow
-non-mesh clients to hook up to the mesh.  This in turn is useful for
-Android phones using &lt;a href=&quot;http://servalproject.org/&quot;&gt;the Serval
-Project&lt;/a&gt; voip client, allowing every one around the playground to
-phone and message each other for free.  The reason is that Android
-phones do not see ad-hoc wifi networks (they are filtered away from
-the GUI view), and can not join the mesh without being rooted.  But if
-they are connected using a normal wifi base station, they can talk to
-every client on the local network.&lt;/p&gt;
-
-&lt;p&gt;To get this working, I&#39;ve created a debian package
-&lt;a href=&quot;https://github.com/petterreinholdtsen/meshfx-node&quot;&gt;meshfx-node&lt;/a&gt;
-and a script
-&lt;a href=&quot;https://github.com/petterreinholdtsen/meshfx-node/blob/master/build-rpi-mesh-node&quot;&gt;build-rpi-mesh-node&lt;/a&gt;
-to create the Raspberry Pi boot image.  I&#39;m using Debian Jessie (and
-not Raspbian), to get more control over the packages available.
-Unfortunately a huge binary blob need to be inserted into the boot
-image to get it booting, but I&#39;ll ignore that for now.  Also, as
-Debian lack support for the CPU features available in the Raspberry
-Pi, the system do not use the hardware floating point unit.  I hope
-the routing performance isn&#39;t affected by the lack of hardware FPU
-support.&lt;/p&gt;
-
-&lt;p&gt;To create an image, run the following with a sudo enabled user
-after inserting the target SD card into the build machine:&lt;/p&gt;
-
-&lt;p&gt;&lt;pre&gt;
-% wget -O build-rpi-mesh-node \
-    https://raw.github.com/petterreinholdtsen/meshfx-node/master/build-rpi-mesh-node
-% sudo bash -x ./build-rpi-mesh-node &gt; build.log 2&gt;&amp;1
-% dd if=/root/rpi/rpi_basic_jessie_$(date +%Y%m%d).img of=/dev/mmcblk0 bs=1M
-%
-&lt;/pre&gt;&lt;/p&gt;
-
-&lt;p&gt;Booting with the resulting SD card on a Raspberry PI with a USB
-wifi card inserted should give you a mesh node.  At least it does for
-me with a the wifi card I am using. The default mesh settings are the
-ones used by the Oslo mesh project at Hackeriet, as I mentioned in
-&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Oslo_community_mesh_network___with_NUUG_and_Hackeriet_at_Hausmania.html&quot;&gt;an
-earlier blog post about this mesh testing&lt;/a&gt;.&lt;/p&gt;
-
-&lt;p&gt;The mesh node was not horribly expensive either.  I bought
-everything over the counter in shops nearby.  If I had ordered online
-from the lowest bidder, the price should be significantly lower:&lt;/p&gt;
-
-&lt;p&gt;&lt;table&gt;
-

-&lt;p&gt;Now my mesh network at home consist of one laptop in the basement
-connected to my production network, one Raspberry Pi node on the 1th
-floor that can be seen by my neighbor across the park, and one
-play-node I use to develop the image building script.  And some times
-I hook up my work horse laptop to the mesh to test it.  I look forward
-to figuring out what kind of latency the batman-adv setup will give,
-and how much packet loss we will experience around the park. :)&lt;/p&gt;

+               <description>&lt;p&gt;&lt;a href=&quot;http://www.nuug.no/&quot;&gt;Foreningen NUUG&lt;/a&gt; melder i natt at
+NRK nå har bestemt seg for
+&lt;a href=&quot;http://www.nuug.no/news/NRK_viser_filmen_om_Datalagringsdirektivet_f_rste_gang_2014_03_31.shtml&quot;&gt;når
+den norske dokumentarfilmen om datalagringsdirektivet skal
+sendes&lt;/a&gt; (se &lt;a href=&quot;http://www.imdb.com/title/tt2832844/&quot;&gt;IMDB&lt;/a&gt;
+for detaljer om filmen) . Første visning blir på NRK2 mandag
+2014-03-31 kl. 19:50, og deretter visninger onsdag 2014-04-02
+kl. 12:30, fredag 2014-04-04 kl. 19:40 og søndag 2014-04-06 kl. 15:10.
+Jeg har sett dokumentaren, og jeg anbefaler enhver å se den selv.  Som
+oppvarming mens vi venter anbefaler jeg Bjørn Stærks kronikk i
+Aftenposten fra i går,
+&lt;a href=&quot;http://www.aftenposten.no/meninger/kronikker/Autoritar-gjokunge-7514915.html&quot;&gt;Autoritær
+gjøkunge&lt;/a&gt;, der han gir en grei skisse av hvor ille det står til med
+retten til privatliv og beskyttelsen av demokrati i Norge og resten
+verden, og helt riktig slår fast at det er vi i databransjen som
+sitter med nøkkelen til å gjøre noe med dette.  Jeg har involvert meg
+i prosjektene &lt;a href=&quot;http://www.dugnadsnett.no/&quot;&gt;dugnadsnett.no&lt;/a&gt;
+og &lt;a href=&quot;https://wiki.debian.org/FreedomBox&quot;&gt;FreedomBox&lt;/a&gt; for å
+forsøke å gjøre litt selv for å bedre situasjonen, men det er mye
+hardt arbeid fra mange flere enn meg som gjenstår før vi kan sies å ha
+gjenopprettet balansen.&lt;/p&gt;
+
+&lt;p&gt;Jeg regner med at nettutgaven dukker opp på
+&lt;a href=&quot;http://tv.nrk.no/program/koid75005313/tema-dine-digitale-spor-datalagringsdirektivet&quot;&gt;NRKs
+side om filmen om datalagringsdirektivet&lt;/a&gt; om fem dager.  Hold et
+øye med siden, og tips venner og slekt om at de også bør se den.&lt;/p&gt;

-                <pubDate>Sat, 19 Oct 2013 10:20:00 +0200</pubDate>
-               <description>&lt;p&gt;Back in 2010, I created a Perl library to talk to
-&lt;a href=&quot;http://en.wikipedia.org/wiki/Spykee&quot;&gt;the Spykee robot&lt;/a&gt;
-(with two belts, wifi, USB and Linux) and made it available from my
-web page.  Today I concluded that it should move to a site that is
-easier to use to cooperate with others, and moved it to github.  If
-you got a Spykee robot, you might want to check out
-&lt;a href=&quot;https://github.com/petterreinholdtsen/libspykee-perl&quot;&gt;the
-libspykee-perl github repository&lt;/a&gt;.&lt;/p&gt;

+               <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Public_Trusted_Timestamping_services_for_everyone.html</guid>

+               <description>&lt;p&gt;Did you ever need to store logs or other files in a way that would
+allow it to be used as evidence in court, and needed a way to
+demonstrate without reasonable doubt that the file had not been
+changed since it was created?  Or, did you ever need to document that
+a given document was received at some point in time, like some
+archived document or the answer to an exam, and not changed after it
+was received?  The problem in these settings is to remove the need to
+trust yourself and your computers, while still being able to prove
+that a file is the same as it was at some given time in the past.&lt;/p&gt;
+
+&lt;p&gt;A solution to these problems is to have a trusted third party
+&quot;stamp&quot; the document and verify that at some given time the document
+looked a given way.  Such
+&lt;a href=&quot;https://en.wikipedia.org/wiki/Notarius&quot;&gt;notarius&lt;/a&gt; service
+have been around for thousands of years, and its digital equivalent is
+called a
+&lt;a href=&quot;http://en.wikipedia.org/wiki/Trusted_timestamping&quot;&gt;trusted
+timestamping service&lt;/a&gt;.  &lt;a href=&quot;http://www.ietf.org/&quot;&gt;The Internet
+Engineering Task Force&lt;/a&gt; standardised how such service could work a
+few years ago as &lt;a href=&quot;http://tools.ietf.org/html/rfc3161&quot;&gt;RFC
+3161&lt;/a&gt;.  The mechanism is simple.  Create a hash of the file in
+question, send it to a trusted third party which add a time stamp to
+the hash and sign the result with its private key, and send back the
+signed hash + timestamp.  Both email, FTP and HTTP can be used to
+request such signature, depending on what is provided by the service
+used. Anyone with the document and the signature can then verify that
+the document matches the signature by creating their own hash and
+checking the signature using the trusted third party public key.
+There are several commercial services around providing such
+timestamping.  A quick search for
+&quot;&lt;a href=&quot;https://duckduckgo.com/?q=rfc+3161+service&quot;&gt;rfc 3161
+service&lt;/a&gt;&quot; pointed me to at least
+&lt;a href=&quot;https://www.digistamp.com/technical/how-a-digital-time-stamp-works/&quot;&gt;DigiStamp&lt;/a&gt;,
+&lt;a href=&quot;http://www.quovadisglobal.co.uk/CertificateServices/SigningServices/TimeStamp.aspx&quot;&gt;Quo
+Vadis&lt;/a&gt;,
+&lt;a href=&quot;https://www.globalsign.com/timestamp-service/&quot;&gt;Global Sign&lt;/a&gt;
+and &lt;a href=&quot;http://www.globaltrustfinder.com/TSADefault.aspx&quot;&gt;Global
+Trust Finder&lt;/a&gt;.  The system work as long as the private key of the
+trusted third party is not compromised.&lt;/p&gt;
+
+&lt;p&gt;But as far as I can tell, there are very few public trusted
+timestamp services available for everyone.  I&#39;ve been looking for one
+for a while now. But yesterday I found one over at
+&lt;a href=&quot;https://www.pki.dfn.de/zeitstempeldienst/&quot;&gt;Deutches
+Forschungsnetz&lt;/a&gt; mentioned in
+&lt;a href=&quot;http://www.d-mueller.de/blog/dealing-with-trusted-timestamps-in-php-rfc-3161/&quot;&gt;a
+blog by David Müller&lt;/a&gt;.  I then found
+&lt;a href=&quot;http://www.rz.uni-greifswald.de/support/dfn-pki-zertifikate/zeitstempeldienst.html&quot;&gt;a
+good recipe on how to use the service&lt;/a&gt; over at the University of
+Greifswald.&lt;/p&gt;
+
+&lt;p&gt;&lt;a href=&quot;http://www.openssl.org/&quot;&gt;The OpenSSL library&lt;/a&gt; contain
+both server and tools to use and set up your own signing service.  See
+the ts(1SSL), tsget(1SSL) manual pages for more details.  The
+following shell script demonstrate how to extract a signed timestamp
+for any file on the disk in a Debian environment:&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
+#!/bin/sh
+set -e
+url=&quot;http://zeitstempel.dfn.de&quot;
+caurl=&quot;https://pki.pca.dfn.de/global-services-ca/pub/cacert/chain.txt&quot;
+reqfile=$(mktemp -t tmp.XXXXXXXXXX.tsq)
+resfile=$(mktemp -t tmp.XXXXXXXXXX.tsr)
+cafile=chain.txt
+if [ ! -f $cafile ] ; then
+    wget -O $cafile &quot;$caurl&quot;
+fi
+openssl ts -query -data &quot;$1&quot; -cert | tee &quot;$reqfile&quot; \
+    | /usr/lib/ssl/misc/tsget -h &quot;$url&quot; -o &quot;$resfile&quot;
+openssl ts -reply -in &quot;$resfile&quot; -text 1&gt;&amp;2
+openssl ts -verify -data &quot;$1&quot; -in &quot;$resfile&quot; -CAfile &quot;$cafile&quot; 1&gt;&amp;2
+base64 &lt; &quot;$resfile&quot;
+rm &quot;$reqfile&quot; &quot;$resfile&quot;
+&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;The argument to the script is the file to timestamp, and the output
+is a base64 encoded version of the signature to STDOUT and details
+about the signature to STDERR.  Note that due to
+&lt;a href=&quot;http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=742553&quot;&gt;a bug
+in the tsget script&lt;/a&gt;, you might need to modify the included script
+and remove the last line.  Or just write your own HTTP uploader using
+curl. :) Now you too can prove and verify that files have not been
+changed.&lt;/p&gt;
+
+&lt;p&gt;But the Internet need more public trusted timestamp services.
+Perhaps something for &lt;a href=&quot;http://www.uninett.no/&quot;&gt;Uninett&lt;/a&gt; or
+my work place the &lt;a href=&quot;http://www.uio.no/&quot;&gt;University of Oslo&lt;/a&gt;
+to set up?&lt;/p&gt;

-               <description>&lt;p&gt;The last few days I came across a few good causes that should get
-wider attention.  I recommend signing and donating to each one of
-these. :)&lt;/p&gt;
-
-&lt;p&gt;Via &lt;a href=&quot;http://www.debian.org/News/weekly/2013/18/&quot;&gt;Debian
-Project News for 2013-10-14&lt;/a&gt; I came across the Outreach Program for
-Women program which is a Google Summer of Code like initiative to get
-more women involved in free software.  One debian sponsor has offered
-to match &lt;a href=&quot;http://debian.ch/opw2013&quot;&gt;any donation done to Debian
-earmarked&lt;/a&gt; for this initiative.  I donated a few minutes ago, and
-hope you will to. :)&lt;/p&gt;
-
-&lt;p&gt;And the Electronic Frontier Foundation just announced plans to
-create &lt;a href=&quot;https://supporters.eff.org/donate/nsa-videos&quot;&gt;video
-documentaries about the excessive spying&lt;/a&gt; on every Internet user that
-take place these days, and their need to fund the work.  I&#39;ve already
-donated.  Are you next?&lt;/p&gt;
-
-&lt;p&gt;For my Norwegian audience, the organisation Studentenes og
-Akademikernes Internasjonale Hjelpefond is collecting signatures for a
-statement under the heading
-&lt;a href=&quot;http://saih.no/Bloggers_United/&quot;&gt;Bloggers United for Open
-Access&lt;/a&gt; for those of us asking for more focus on open access in the
-Norwegian government.  So far 499 signatures.  I hope you will sign it
-too.&lt;/p&gt;

+               <description>&lt;p&gt;Keeping your DVD collection safe from scratches and curious
+children fingers while still having it available when you want to see a
+movie is not straight forward.  My preferred method at the moment is
+to store a full copy of the ISO on a hard drive, and use VLC, Popcorn
+Hour or other useful players to view the resulting file.  This way the
+subtitles and bonus material are still available and using the ISO is
+just like inserting the original DVD record in the DVD player.&lt;/p&gt;
+
+&lt;p&gt;Earlier I used dd for taking security copies, but it do not handle
+DVDs giving read errors (which are quite a few of them).  I&#39;ve also
+tried using
+&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Ripping_problematic_DVDs_using_dvdbackup_and_genisoimage.html&quot;&gt;dvdbackup
+and genisoimage&lt;/a&gt;, but these days I use the marvellous python library
+and program
+&lt;a href=&quot;http://bblank.thinkmo.de/blog/new-software-python-dvdvideo&quot;&gt;python-dvdvideo&lt;/a&gt;
+written by Bastian Blank.  It is
+&lt;a href=&quot;http://packages.qa.debian.org/p/python-dvdvideo.html&quot;&gt;in Debian
+already&lt;/a&gt; and the binary package name is python3-dvdvideo. Instead
+of trying to read every block from the DVD, it parses the file
+structure and figure out which block on the DVD is actually in used,
+and only read those blocks from the DVD.  This work surprisingly well,
+and I have been able to almost backup my entire DVD collection using
+this method.&lt;/p&gt;
+
+&lt;p&gt;So far, python-dvdvideo have failed on between 10 and
+20 DVDs, which is a small fraction of my collection.  The most common
+problem is
+&lt;a href=&quot;https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=720831&quot;&gt;DVDs
+using UTF-16 instead of UTF-8 characters&lt;/a&gt;, which according to
+Bastian is against the DVD specification (and seem to cause some
+players to fail too).  A rarer problem is what seem to be inconsistent
+DVD structures, as the python library
+&lt;a href=&quot;https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=723079&quot;&gt;claim
+there is a overlap between objects&lt;/a&gt;.  An equally rare problem claim
+&lt;a href=&quot;https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=741878&quot;&gt;some
+value is out of range&lt;/a&gt;.  No idea what is going on there.  I wish I
+knew enough about the DVD format to fix these, to ensure my movie
+collection will stay with me in the future.&lt;/p&gt;
+
+&lt;p&gt;So, if you need to keep your DVDs safe, back them up using
+python-dvdvideo. :)&lt;/p&gt;

-               <description>&lt;p&gt;Wireless mesh networks are self organising and self healing
-networks that can be used to connect computers across small and large
-areas, depending on the radio technology used.  Normal wifi equipment
-can be used to create home made radio networks, and there are several
-successful examples like
-&lt;a href=&quot;http://www.freifunk.net/&quot;&gt;Freifunk&lt;/a&gt; and
-&lt;a href=&quot;http://www.awmn.net/&quot;&gt;Athens Wireless Metropolitan Network&lt;/a&gt;
-(see
-&lt;a href=&quot;http://en.wikipedia.org/wiki/List_of_wireless_community_networks_by_region#Greece&quot;&gt;wikipedia
-for a large list&lt;/a&gt;) around the globe.  To give you an idea how it
-work, check out the nice overview of the Kiel Freifunk community which
-can be seen from their
-&lt;a href=&quot;http://freifunk.in-kiel.de/ffmap/nodes.html&quot;&gt;dynamically
-updated node graph and map&lt;/a&gt;, where one can see how the mesh nodes
-automatically handle routing and recover from nodes disappearing.
-There is also a small community mesh network group in Oslo, Norway,
-and that is the main topic of this blog post.&lt;/p&gt;
-
-&lt;p&gt;I&#39;ve wanted to check out mesh networks for a while now, and hoped
-to do it as part of my involvement with the &lt;a
-href=&quot;http://www.nuug.no/&quot;&gt;NUUG member organisation&lt;/a&gt; community, and
-my recent involvement in
-&lt;a href=&quot;https://wiki.debian.org/FreedomBox&quot;&gt;the Freedombox project&lt;/a&gt;
-finally lead me to give mesh networks some priority, as I suspect a
-Freedombox should use mesh networks to connect neighbours and family
-when possible, given that most communication between people are
-between those nearby (as shown for example by research on Facebook
-communication patterns).  It also allow people to communicate without
-any central hub to tap into for those that want to listen in on the
-private communication of citizens, which have become more and more
-important over the years.&lt;/p&gt;
-
-&lt;p&gt;So far I have only been able to find one group of people in Oslo
-working on community mesh networks, over at the hack space
-&lt;a href=&quot;http://hackeriet.no/&quot;&gt;Hackeriet&lt;/a&gt; at Husmania.  They seem to
-have started with some Freifunk based effort using OLSR, called
-&lt;a href=&quot;http://oslo.freifunk.net/index.php?title=Main_Page&quot;&gt;the Oslo
-Freifunk project&lt;/a&gt;, but that effort is now dead and the people
-behind it have moved on to a batman-adv based system called
-&lt;a href=&quot;http://meshfx.org/trac&quot;&gt;meshfx&lt;/a&gt;.  Unfortunately the wiki
-site for the Oslo Freifunk project is no longer possible to update to
-reflect this fact, so the old project page can&#39;t be updated to point to
-the new project.  A while back, the people at Hackeriet invited people
-from the Freifunk community to Oslo to talk about mesh networks.  I
-came across this video where Hans Jørgen Lysglimt interview the
-speakers about this talk (from
-&lt;a href=&quot;https://www.youtube.com/watch?v=N2Kd7CLkhSY&quot;&gt;youtube&lt;/a&gt;):&lt;/p&gt;
-
-&lt;p&gt;&lt;iframe width=&quot;420&quot; height=&quot;315&quot; src=&quot;https://www.youtube.com/embed/N2Kd7CLkhSY&quot; frameborder=&quot;0&quot; allowfullscreen&gt;&lt;/iframe&gt;&lt;/p&gt;
-
-&lt;p&gt;I mentioned OLSR and batman-adv, which are mesh routing protocols.
-There are heaps of different protocols, and I am still struggling to
-figure out which one would be &quot;best&quot; for some definitions of best, but
-given that the community mesh group in Oslo is so small, I believe it
-is best to hook up with the existing one instead of trying to create a
-completely different setup, and thus I have decided to focus on
-batman-adv for now.  It sure help me to  know that the very cool
-&lt;a href=&quot;http://www.servalproject.org/&quot;&gt;Serval project in Australia&lt;/a&gt;
-is using batman-adv as their meshing technology when it create a self
-organizing and self healing telephony system for disaster areas and
-less industrialized communities.  Check out this cool video presenting
-that project (from
-&lt;a href=&quot;https://www.youtube.com/watch?v=30qNfzJCQOA&quot;&gt;youtube&lt;/a&gt;):&lt;/p&gt;
-
-&lt;p&gt;&lt;iframe width=&quot;560&quot; height=&quot;315&quot; src=&quot;https://www.youtube.com/embed/30qNfzJCQOA&quot; frameborder=&quot;0&quot; allowfullscreen&gt;&lt;/iframe&gt;&lt;/p&gt;
-
-&lt;p&gt;According to the wikipedia page on
-&lt;a href=&quot;http://en.wikipedia.org/wiki/Wireless_mesh_network&quot;&gt;Wireless
-mesh network&lt;/a&gt; there are around 70 competing schemes for routing
-packets across mesh networks, and OLSR, B.A.T.M.A.N. and
-B.A.T.M.A.N. advanced are protocols used by several free software
-based community mesh networks.&lt;/p&gt;
-
-&lt;p&gt;The batman-adv protocol is a bit special, as it provide layer 2
-(as in ethernet ) routing, allowing ipv4 and ipv6 to work on the same
-network.  One way to think about it is that it provide a mesh based
-vlan you can bridge to or handle like any other vlan connected to your
-computer.  The required drivers are already in the Linux kernel at
-least since Debian Wheezy, and it is fairly easy to set up.  A
-&lt;a href=&quot;http://www.open-mesh.org/projects/batman-adv/wiki/Quick-start-guide&quot;&gt;good
-introduction&lt;/a&gt; is available from the Open Mesh project.  These are

+               <description>&lt;p&gt;Det offentlige Norge har mye kunnskap og informasjon.  Men hvordan
+kan en få tilgang til den på en enkel måte?  Takket være et lite
+knippe lover og tilhørende forskrifter, blant annet
+&lt;a href=&quot;http://lovdata.no/dokument/NL/lov/2006-05-19-16&quot;&gt;offentlighetsloven&lt;/a&gt;,
+&lt;a href=&quot;http://lovdata.no/dokument/NL/lov/2003-05-09-31&quot;&gt;miljøinformasjonsloven&lt;/a&gt;
+og
+&lt;a href=&quot;http://lovdata.no/dokument/NL/lov/1967-02-10/&quot;&gt;forvaltningsloven&lt;/a&gt;
+har en rett til å spørre det offentlige og få svar.  Men det finnes
+intet offentlig arkiv over hva andre har spurt om, og dermed risikerer en
+å måtte forstyrre myndighetene gang på gang for å få tak i samme
+informasjonen på nytt.  &lt;a href=&quot;http://www.mysociety.org/&quot;&gt;Britiske
+mySociety&lt;/a&gt; har laget tjenesten
+&lt;a href=&quot;http://www.whatdotheyknow.com/&quot;&gt;WhatDoTheyKnow&lt;/a&gt; som gjør
+noe med dette.  I Storbritannia blir WhatdoTheyKnow brukt i
+&lt;a href=&quot;http://www.mysociety.org/2011/07/01/whatdotheyknows-share-of-central-government-foi-requests-q2-2011/&quot;&gt;ca
+15% av alle innsynsforespørsler mot sentraladministrasjonen&lt;/a&gt;.
+Prosjektet heter &lt;a href=&quot;http://www.alaveteli.org/&quot;&gt;Alaveteli&lt;/A&gt;, og
+er takk i bruk en rekke steder etter at løsningen ble generalisert og
+gjort mulig å oversette.  Den hjelper borgerne med å be om innsyn,
+rådgir ved purringer og klager og lar alle se hvilke henvendelser som
+er sendt til det offentlige og hvilke svar som er kommet inn, i et
+søkpart arkiv.  Her i Norge holder vi i foreningen NUUG på å få opp en
+norsk utgave av Alaveteli, og her trenger vi din hjelp med
+oversettelsen.&lt;/p&gt;
+
+&lt;p&gt;Så langt er 76 % av Alaveteli oversatt til norsk bokmål, men vi
+skulle gjerne vært oppe i 100 % før lansering.  Oversettelsen gjøres
+på &lt;a href=&quot;https://www.transifex.com/projects/p/alaveteli/&quot;&gt;Transifex,
+der enhver som registrerer seg&lt;/a&gt; og ber om tilgang til
+bokmålsoversettelsen får bidra.  Vi har satt opp en test av tjenesten
+(som ikke sender epost til det offentlige, kun til oss som holder på å
+sette opp tjenesten) på maskinen
+&lt;a href=&quot;http://alaveteli-dev.nuug.no/&quot;&gt;alaveteli-dev.nuug.no&lt;/a&gt;, der
+en kan se hvordan de oversatte meldingen blir seende ut på nettsiden.
+Når tjenesten lanseres vil den hete
+&lt;a href=&quot;https://www.mimesbrønn.no/&quot;&gt;Mimes brønn&lt;/a&gt;, etter
+visdomskilden som Odin måtte gi øyet sitt for å få drikke i.  Den
+nettsiden er er ennå ikke klar til bruk.&lt;/p&gt;
+
+&lt;p&gt;Hvis noen vil oversette til nynorsk også, så skal vi finne ut
+hvordan vi lager en flerspråklig tjeneste.  Men i første omgang er
+fokus på bokmålsoversettelsen, der vi selv har nok peiling til å ha
+fått oversatt 76%, men trenger hjelp for å komme helt i mål. :)&lt;/p&gt;

+               <description>&lt;p&gt;The &lt;a href=&quot;https://wiki.debian.org/FreedomBox&quot;&gt;Freedombox
+project&lt;/a&gt; is working on providing the software and hardware for
+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).&lt;/p&gt;
+
+&lt;p&gt;And what day could be better than the Pi day to announce that the
+new version will provide &quot;hard drive&quot; / 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
+&lt;a href=&quot;http://packages.qa.debian.org/vmdebootstrap&quot;&gt;vmdebootstrap&lt;/a&gt;
+with a user with sudo access to become root:

 
 

-&lt;p&gt;&lt;table&gt;
-&lt;tr&gt;&lt;th&gt;Setting&lt;/th&gt;&lt;th&gt;Value&lt;/th&gt;&lt;/tr&gt;
-&lt;tr&gt;&lt;td&gt;Protocol / kernel module&lt;/td&gt;&lt;td&gt;batman-adv&lt;/td&gt;&lt;/tr&gt;
-&lt;tr&gt;&lt;td&gt;ESSID&lt;/td&gt;&lt;td&gt;meshfx@hackeriet&lt;/td&gt;&lt;/tr&gt;
-&lt;td&gt;Channel / Frequency&lt;/td&gt;&lt;td&gt;11 / 2462&lt;/td&gt;&lt;/tr&gt;
-&lt;td&gt;Cell ID&lt;/td&gt;&lt;td&gt;02:BA:00:00:00:01&lt;/td&gt;
-&lt;/table&gt;&lt;/p&gt;
+&lt;pre&gt;
+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
+&lt;/pre&gt;
+
+&lt;p&gt;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 &lt;a
+href=&quot;https://bugs.debian.org/741407&quot;&gt;a race condition in
+vmdebootstrap&lt;/a&gt;, the build might fail without the patch to the
+kpartx call.&lt;/p&gt;
+
+&lt;p&gt;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:&lt;/p&gt;
+
+&lt;pre&gt;
+url=&lt;a href=&quot;http://www.reinholdtsen.name/freedombox/preseed-jessie.dat&quot;&gt;http://www.reinholdtsen.name/freedombox/preseed-jessie.dat&lt;/a&gt;
+&lt;/pre&gt;

 
 

-&lt;p&gt;The reason for setting ad-hoc wifi Cell ID is to work around bugs
-in firmware used in wifi card and wifi drivers.  (See a nice post from
-VillageTelco about
-&quot;&lt;a href=&quot;http://tiebing.blogspot.no/2009/12/ad-hoc-cell-splitting-re-post-original.html&quot;&gt;Information
-about cell-id splitting, stuck beacons, and failed IBSS merges!&lt;/a&gt;
-for details.)  When these settings are activated and you have some
-other mesh node nearby, your computer will be connected to the mesh
-network and can communicate with any mesh node that is connected to
-any of the nodes in your network of nodes. :)&lt;/p&gt;
-
-&lt;p&gt;My initial plan was to reuse my old Linksys WRT54GL as a mesh node,
-but that seem to be very hard, as I have not been able to locate a
-firmware supporting batman-adv.  If anyone know how to use that old
-wifi access point with batman-adv these days, please let me know.&lt;/p&gt;
-
-&lt;p&gt;If you find this project interesting and want to join, please join
-us on IRC, either channel
-&lt;a href=&quot;irc://irc.freenode.net/#oslohackerspace&quot;&gt;#oslohackerspace&lt;/a&gt;
-or &lt;a href=&quot;irc://irc.freenode.net/#nuug&quot;&gt;#nuug&lt;/a&gt; on
-irc.freenode.net.&lt;/p&gt;
-
-&lt;p&gt;While investigating mesh networks in Oslo, I came across an old
-research paper from the university of Stavanger and Telenor Research
-and Innovation called
-&lt;a href=&quot;http://folk.uio.no/paalee/publications/netrel-egeland-iswcs-2008.pdf&quot;&gt;The
-reliability of wireless backhaul mesh networks&lt;/a&gt; and elsewhere
-learned that Telenor have been experimenting with mesh networks at
-Grünerløkka in Oslo.  So mesh networks are also interesting for
-commercial companies, even though Telenor discovered that it was hard
-to figure out a good business plan for mesh networking and as far as I
-know have closed down the experiment.  Perhaps Telenor or others would
-be interested in a cooperation?&lt;/p&gt;
-
-&lt;p&gt;&lt;strong&gt;Update 2013-10-12&lt;/strong&gt;: I was just
-&lt;a href=&quot;http://lists.alioth.debian.org/pipermail/freedombox-discuss/2013-October/005900.html&quot;&gt;told
-by the Serval project developers&lt;/a&gt; that they no longer use
-batman-adv (but are compatible with it), but their own crypto based
-mesh system.&lt;/p&gt;
+&lt;p&gt;But note that due to &lt;a href=&quot;https://bugs.debian.org/740673&quot;&gt;a
+recently introduced bug in apt in Jessie&lt;/a&gt;, the installer will
+currently hang while setting up APT sources.  Killing the
+&#39;&lt;tt&gt;apt-cdrom ident&lt;/tt&gt;&#39; 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.&lt;/p&gt;
+
+&lt;p&gt;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
+&lt;a href=&quot;irc://irc.debian.org:6667/%23freedombox&quot;&gt;IRC (#freedombox on
+irc.debian.org)&lt;/a&gt; and
+&lt;a href=&quot;http://lists.alioth.debian.org/mailman/listinfo/freedombox-discuss&quot;&gt;the
+mailing list&lt;/a&gt; if you want to help make this vision come true.&lt;/p&gt;
