-
-<pre>
-The Debian Edu Team is pleased to announce the release of Debian Edu
-Jessie 8.0+edu0~alpha0
-
-Debian Edu is a complete operating system for schools. Through its
-various installation profiles you can install servers, workstations
-and laptops which will work together on the school network. With
-Debian Edu, the teachers themselves or their technical support can
-roll out a complete multi-user multi-machine study environment within
-hours or a few days. Debian Edu comes with hundreds of applications
-pre-installed, but you can always add more packages from Debian.
-
-For those who want to give Debian Edu Jessie a try, download and
-installation instructions are available, including detailed
-instructions in the manual[1] explaining the first steps, such as
-setting up a network or adding users. Please note that the password
-for the user your prompted for during installation must have a length
-of at least 5 characters!

-Would you like to give your school's computer a longer life? Are you
-tired of sneaker administration, running from computer to computer
-reinstalling the operating system? Would you like to administrate all
-the computers in your school using only a couple of hours every week?
-Check out Debian Edu Jessie!
-
-Skolelinux is used by at least two hundred schools all over the world,
-mostly in Germany and Norway.

-About Debian Edu and Skolelinux
-===============================
-
-Debian Edu, also known as Skolelinux[2], 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 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 more than 60 educational software
-packages[3] and more are available from the Debian archive, and
-schools can choose between KDE, Gnome, LXDE, Xfce and MATE desktop
-environment.

+ <description><p>For almost a year now, we have been working on making a Norwegian
+Bokmål edition of <a href="https://debian-handbook.info/">The Debian
+Administrator's Handbook</a>. Now, thanks to the tireless effort of
+Ole-Erik, Ingrid and Andreas, the initial translation is complete, and
+we are working on the proof reading to ensure consistent language and
+use of correct computer science terms. The plan is to make the book
+available on paper, as well as in electronic form. For that to
+happen, the proof reading must be completed and all the figures need
+to be translated. If you want to help out, get in touch.</p>
+
+<p><a href="http://people.skolelinux.org/pere/debian-handbook/debian-handbook-nb-NO.pdf">A
+
+fresh PDF edition</a> in A4 format (the final book will have smaller
+pages) of the book created every morning is available for
+proofreading. If you find any errors, please
+<a href="https://hosted.weblate.org/projects/debian-handbook/">visit
+Weblate and correct the error</a>. The
+<a href="http://l.github.io/debian-handbook/stat/nb-NO/index.html">state
+of the translation including figures</a> is a useful source for those

+ <title>Unlimited randomness with the ChaosKey?</title>

+ <description><p>A few days ago I ordered a small batch of
+<a href="http://altusmetrum.org/ChaosKey/">the ChaosKey</a>, a small
+USB dongle for generating entropy created by Bdale Garbee and Keith
+Packard. Yesterday it arrived, and I am very happy to report that it
+work great! According to its designers, to get it to work out of the
+box, you need the Linux kernel version 4.1 or later. I tested on a
+Debian Stretch machine (kernel version 4.9), and there it worked just
+fine, increasing the available entropy very quickly. I wrote a small
+test oneliner to test. It first print the current entropy level,
+drain /dev/random, and then print the entropy level for five seconds.
+Here is the situation without the ChaosKey inserted:</p>
+
+<blockquote><pre>
+% cat /proc/sys/kernel/random/entropy_avail; \
+ dd bs=1M if=/dev/random of=/dev/null count=1; \
+ for n in $(seq 1 5); do \
+ cat /proc/sys/kernel/random/entropy_avail; \
+ sleep 1; \
+ done
+300
+0+1 oppføringer inn
+0+1 oppføringer ut
+28 byte kopiert, 0,000264565 s, 106 kB/s
+4
+8
+12
+17
+21
+%
+</pre></blockquote>
+
+<p>The entropy level increases by 3-4 every second. In such case any
+application requiring random bits (like a HTTPS enabled web server)
+will halt and wait for more entrpy. And here is the situation with
+the ChaosKey inserted:</p>
+
+<blockquote><pre>
+% cat /proc/sys/kernel/random/entropy_avail; \
+ dd bs=1M if=/dev/random of=/dev/null count=1; \
+ for n in $(seq 1 5); do \
+ cat /proc/sys/kernel/random/entropy_avail; \
+ sleep 1; \
+ done
+1079
+0+1 oppføringer inn
+0+1 oppføringer ut
+104 byte kopiert, 0,000487647 s, 213 kB/s
+433
+1028
+1031
+1035
+1038
+%
+</pre></blockquote>
+
+<p>Quite the difference. :) I bought a few more than I need, in case
+someone want to buy one here in Norway. :)</p>
+
+<p>Update: The dongle was presented at Debconf last year. You might
+find <a href="https://debconf16.debconf.org/talks/94/">the talk
+recording illuminating</a>. It explains exactly what the source of
+randomness is, if you are unable to spot it from the schema drawing
+available from the ChaosKey web site linked at the start of this blog
+post.</p>
