                <description>&lt;p&gt;The &lt;a href=&quot;https://www.debian.org/&quot;&gt;Debian&lt;/a&gt; installer could be
a lot quicker.  When we install more than 2000 packages in
&lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux / Debian Edu&lt;/a&gt; using
tasksel in the installer, unpacking the binary packages take forever.
A part of the slow I/O issue was discussed in
&lt;a href=&quot;https://bugs.debian.org/613428&quot;&gt;bug #613428&lt;/a&gt; about too
much file system sync-ing done by dpkg, which is the package
responsible for unpacking the binary packages.  Other parts (like code
executed by postinst scripts) might also sync to disk during
installation.  All this sync-ing to disk do not really make sense to
me.  If the machine crash half-way through, I start over, I do not try
to salvage the half installed system.  So the failure sync-ing is
supposed to protect against, hardware or system crash, is not really
relevant while the installer is running.&lt;/p&gt;

&lt;p&gt;A few days ago, I thought of a way to get rid of all the file
system sync()-ing in a fairly non-intrusive way, without the need to
change the code in several packages.  The idea is not new, but I have
not heard anyone propose the approach using dpkg-divert before.  It
depend on the small and clever package
&lt;a href=&quot;https://packages.qa.debian.org/eatmydata&quot;&gt;eatmydata&lt;/a&gt;, which
uses LD_PRELOAD to replace the system functions for syncing data to
disk with functions doing nothing, thus allowing programs to live
dangerous while speeding up disk I/O significantly.  Instead of
modifying the implementation of dpkg, apt and tasksel (which are the
packages responsible for selecting, fetching and installing packages),
it occurred to me that we could just divert the programs away, replace
them with a simple shell wrapper calling
&quot;eatmydata&amp;nbsp;$program&amp;nbsp;$@&quot;, to get the same effect.
Yesterday I decided to test the idea, and wrapped up a simple
implementation for the Debian Edu udeb.&lt;/p&gt;

&lt;p&gt;The effect was stunning.  In my first test it reduced the running
time of the pkgsel step (installing tasks) from 64 to less than 44
minutes (20 minutes shaved off the installation) on an old Dell
Latitude D505 machine.  I am not quite sure what the optimised time
would have been, as I messed up the testing a bit, causing the debconf
priority to get low enough for two questions to pop up during
installation.  As soon as I saw the questions I moved the installation
along, but do not know how long the question were holding up the
installation.  I did some more measurements using Debian Edu Jessie,
and got these results.  The time measured is the time stamp in
/var/log/syslog between the &quot;pkgsel: starting tasksel&quot; and the
&quot;pkgsel: finishing up&quot; lines, if you want to do the same measurement
yourself.  In Debian Edu, the tasksel dialog do not show up, and the
timing thus do not depend on how quickly the user handle the tasksel
dialog.&lt;/p&gt;

&lt;p&gt;&lt;table&gt;

&lt;tr&gt;
&lt;th&gt;Machine/setup&lt;/th&gt;
&lt;th&gt;Original tasksel&lt;/th&gt;
&lt;th&gt;Optimised tasksel&lt;/th&gt;
&lt;th&gt;Reduction&lt;/th&gt;
&lt;/tr&gt;

&lt;tr&gt;
&lt;td&gt;Latitude D505 Main+LTSP LXDE&lt;/td&gt;
&lt;td&gt;64 min (07:46-08:50)&lt;/td&gt;
&lt;td&gt;&lt;44 min (11:27-12:11)&lt;/td&gt;
&lt;td&gt;&gt;20 min 18%&lt;/td&gt;
&lt;/tr&gt;

&lt;tr&gt;
&lt;td&gt;Latitude D505 Roaming LXDE&lt;/td&gt;
&lt;td&gt;57 min (08:48-09:45)&lt;/td&gt;
&lt;td&gt;34 min (07:43-08:17)&lt;/td&gt;
&lt;td&gt;23 min 40%&lt;/td&gt;
&lt;/tr&gt;

&lt;tr&gt;
&lt;td&gt;Latitude D505 Minimal&lt;/td&gt;
&lt;td&gt;22 min (10:37-10:59)&lt;/td&gt;
&lt;td&gt;11 min (11:16-11:27)&lt;/td&gt;
&lt;td&gt;11 min 50%&lt;/td&gt;
&lt;/tr&gt;

&lt;tr&gt;
&lt;td&gt;Thinkpad X200 Minimal&lt;/td&gt;
&lt;td&gt;6 min (08:19-08:25)&lt;/td&gt;
&lt;td&gt;4 min (08:04-08:08)&lt;/td&gt;
&lt;td&gt;2 min 33%&lt;/td&gt;
&lt;/tr&gt;

&lt;tr&gt;
&lt;td&gt;Thinkpad X200 Roaming KDE&lt;/td&gt;
&lt;td&gt;19 min (09:21-09:40)&lt;/td&gt;
&lt;td&gt;15 min (10:25-10:40)&lt;/td&gt;
&lt;td&gt;4 min 21%&lt;/td&gt;
&lt;/tr&gt;

&lt;/table&gt;&lt;/p&gt;

&lt;p&gt;The test is done using a netinst ISO on a USB stick, so some of the
time is spent downloading packages.  The connection to the Internet
was 100Mbit/s during testing, so downloading should not be a
significant factor in the measurement.  Download typically took a few
seconds to a few minutes, depending on the amount of packages being
installed.&lt;/p&gt;

&lt;p&gt;The speedup is implemented by using two hooks in
&lt;a href=&quot;https://www.debian.org/devel/debian-installer/&quot;&gt;Debian
Installer&lt;/a&gt;, the pre-pkgsel.d hook to set up the diverts, and the
finish-install.d hook to remove the divert at the end of the
installation.  I picked the pre-pkgsel.d hook instead of the
post-base-installer.d hook because I test using an ISO without the
eatmydata package included, and the post-base-installer.d hook in
Debian Edu can only operate on packages included in the ISO.  The
negative effect of this is that I am unable to activate this
optimization for the kernel installation step in d-i.  If the code is
moved to the post-base-installer.d hook, the speedup would be larger
for the entire installation.&lt;/p&gt;

&lt;p&gt;I&#39;ve implemented this in the
&lt;a href=&quot;https://packages.qa.debian.org/debian-edu-install&quot;&gt;debian-edu-install&lt;/a&gt;
git repository, and plan to provide the optimization as part of the
Debian Edu installation.  If you want to test this yourself, you can
create two files in the installer (or in an udeb).  One shell script
need do go into /usr/lib/pre-pkgsel.d/, with content like this:&lt;/p&gt;

&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
#!/bin/sh
set -e
. /usr/share/debconf/confmodule
info() {
    logger -t my-pkgsel &quot;info: $*&quot;
}
error() {
    logger -t my-pkgsel &quot;error: $*&quot;
}
override_install() {
    apt-install eatmydata || true
    if [ -x /target/usr/bin/eatmydata ] ; then
        for bin in dpkg apt-get aptitude tasksel ; do
            file=/usr/bin/$bin
            # Test that the file exist and have not been diverted already.
            if [ -f /target$file ] ; then
                info &quot;diverting $file using eatmydata&quot;
                printf &quot;#!/bin/sh\neatmydata $bin.distrib \&quot;\$@\&quot;\n&quot; \
                    &gt; /target$file.edu
                chmod 755 /target$file.edu
                in-target dpkg-divert --package debian-edu-config \
                    --rename --quiet --add $file
                ln -sf ./$bin.edu /target$file
            else
                error &quot;unable to divert $file, as it is missing.&quot;
            fi
        done
    else
        error &quot;unable to find /usr/bin/eatmydata after installing the eatmydata pacage&quot;
    fi
}

override_install
&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;

&lt;p&gt;To clean up, another shell script should go into
/usr/lib/finish-install.d/ with code like this:

&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
#! /bin/sh -e
. /usr/share/debconf/confmodule
error() {
    logger -t my-finish-install &quot;error: $@&quot;
}
remove_install_override() {
    for bin in dpkg apt-get aptitude tasksel ; do
        file=/usr/bin/$bin
        if [ -x /target$file.edu ] ; then
            rm /target$file
            in-target dpkg-divert --package debian-edu-config \
                --rename --quiet --remove $file
            rm /target$file.edu
        else
            error &quot;Missing divert for $file.&quot;
        fi
    done
    sync # Flush file buffers before continuing
}

remove_install_override
&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;

&lt;p&gt;In Debian Edu, I placed both code fragments in a separate script
edu-eatmydata-install and call it from the pre-pkgsel.d and
finish-install.d scripts.&lt;/p&gt;

&lt;p&gt;By now you might ask if this change should get into the normal
Debian installer too?  I suspect it should, but am not sure the
current debian-installer coordinators find it useful enough.  It also
depend on the side effects of the change.  I&#39;m not aware of any, but I
guess we will see if the change is safe after some more testing.
Perhaps there is some package in Debian depending on sync() and
fsync() having effect?  Perhaps it should go into its own udeb, to
allow those of us wanting to enable it to do so without affecting
everyone.&lt;/p&gt;

                <pubDate>Wed, 10 Sep 2014 13:10:00 +0200</pubDate>
                <description>&lt;p&gt;Yesterday, I had the pleasure of attending a talk with the
&lt;a href=&quot;http://www.nuug.no/&quot;&gt;Norwegian Unix User Group&lt;/a&gt; about
&lt;a href=&quot;http://www.nuug.no/aktiviteter/20140909-sks-keyservers/&quot;&gt;the
OpenPGP keyserver pool sks-keyservers.net&lt;/a&gt;, and was very happy to
learn that there is a large set of publicly available key servers to
use when looking for peoples public key.  So far I have used
subkeys.pgp.net, and some times wwwkeys.nl.pgp.net when the former
were misbehaving, but those days are ended.  The servers I have used
up until yesterday have been slow and some times unavailable.  I hope
those problems are gone now.&lt;/p&gt;

&lt;p&gt;Behind the round robin DNS entry of the
&lt;a href=&quot;https://sks-keyservers.net/&quot;&gt;sks-keyservers.net&lt;/a&gt; service
there is a pool of more than 100 keyservers which are checked every
day to ensure they are well connected and up to date.  It must be
better than what I have used so far. :)&lt;/p&gt;

&lt;p&gt;Yesterdays speaker told me that the service is the default
keyserver provided by the default configuration in GnuPG, but this do
not seem to be used in Debian.  Perhaps it should?&lt;/p&gt;

&lt;p&gt;Anyway, I&#39;ve updated my ~/.gnupg/options file to now include this
line:&lt;/p&gt;

&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
keyserver pool.sks-keyservers.net
&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;

&lt;p&gt;With GnuPG version 2 one can also locate the keyserver using SRV
entries in DNS.  Just for fun, I did just that at work, so now every
user of GnuPG at the University of Oslo should find a OpenGPG
keyserver automatically should their need it:&lt;/p&gt;

&lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
% host -t srv _pgpkey-http._tcp.uio.no
_pgpkey-http._tcp.uio.no has SRV record 0 100 11371 pool.sks-keyservers.net.
%
&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;

&lt;p&gt;Now if only
&lt;a href=&quot;http://ietfreport.isoc.org/idref/draft-shaw-openpgp-hkp/&quot;&gt;the
HKP lookup protocol&lt;/a&gt; supported finding signature paths, I would be
very happy.  It can look up a given key or search for a user ID, but I
normally do not want that, but to find a trust path from my key to
another key.  Given a user ID or key ID, I would like to find (and
download) the keys representing a signature path from my key to the
key in question, to be able to get a trust path between the two keys.
This is as far as I can tell not possible today.  Perhaps something
for a future version of the protocol?&lt;/p&gt;

                <title>Do you need an agreement with MPEG-LA to publish and broadcast H.264 video in Norway?</title>
                <link>http://people.skolelinux.org/pere/blog/Do_you_need_an_agreement_with_MPEG_LA_to_publish_and_broadcast_H_264_video_in_Norway_.html</link>

                <pubDate>Mon, 25 Aug 2014 22:10:00 +0200</pubDate>
                <description>&lt;p&gt;Two years later, I am still not sure if it is legal here in Norway
to use or publish a video in H.264 or MPEG4 format edited by the
commercially licensed video editors, without limiting the use to
create &quot;personal&quot; or &quot;non-commercial&quot; videos or get a license
agreement with &lt;a href=&quot;http://www.mpegla.com&quot;&gt;MPEG LA&lt;/a&gt;.  If one
want to publish and broadcast video in a non-personal or commercial
setting, it might be that those tools can not be used, or that video
format can not be used, without breaking their copyright license.  I
am not sure.
&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Trenger_en_avtale_med_MPEG_LA_for___publisere_og_kringkaste_H_264_video_.html&quot;&gt;Back
then&lt;/a&gt;, I found that the copyright license terms for Adobe Premiere
and Apple Final Cut Pro both specified that one could not use the
program to produce anything else without a patent license from MPEG
LA.  The issue is not limited to those two products, though.  Other
much used products like those from Avid and Sorenson Media have terms
of use are similar to those from Adobe and Apple.  The complicating
factor making me unsure if those terms have effect in Norway or not is
that the patents in question are not valid in Norway, but copyright
licenses are.&lt;/p&gt;

&lt;p&gt;These are the terms for Avid Artist Suite, according to their
&lt;a href=&quot;http://www.avid.com/US/about-avid/legal-notices/legal-enduserlicense2&quot;&gt;published
end user&lt;/a&gt;
&lt;a href=&quot;http://www.avid.com/static/resources/common/documents/corporate/LICENSE.pdf&quot;&gt;license

                <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Bernd_Zeitzen.html</guid>
                <pubDate>Thu, 31 Jul 2014 08:30:00 +0200</pubDate>
                <description>&lt;p&gt;The complete and free “out of the box” software solution for
schools, &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu /
Skolelinux&lt;/a&gt;, is used quite a lot in Germany, and one of the people
involved is Bernd Zeitzen, who show up on the project mailing lists
from time to time with interesting questions and tips on how to adjust
the setup.  I managed to interview him this summer.&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 Bernd Zeitzen and I&#39;m married with Hedda, a self
employed physiotherapist.  My former profession is tool maker, but I
haven&#39;t worked for 30 years in this job.  30 years ago I started to
support my wife and become her officeworker and a few years later the
administrator for a small computer network, today based on Ubuntu
Server (Samba, OpenVPN). For her daily work she has to use Windows
Desktops because the software she needs to organize her business only
works with Windows . :-(&lt;/p&gt;

&lt;p&gt;In 1988 we started with one PC and DOS, then I learned to use
Windows 98, 2000, XP, …, 8, Ubuntu, MacOSX.  Today we are running a
Linux server with 6 Windows clients and 10 persons (teacher of
children with special needs, speech therapist, occupational therapist,
psychologist and officeworkers) using our Samba shares via OpenVPN to
work with the documentations of our patients.&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;Two years ago a friend of mine asked me, if I want to get a job in
his school (&lt;a href=&quot;http://www.gymnasium-harsewinkel.de/&quot;&gt;Gymnasium
Harsewinkel&lt;/a&gt;).  They started with Skolelinux / Debian Edu and they
were looking for people to give support to the teachers using the
software and the network and teaching the pupils increasing their
computer skills in optional lessons.  I&#39;m spending 4-6 hours a week
with this job.&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;The independence.&lt;/p&gt;

&lt;p&gt;First: Every person is allowed to use, share and develop the
software. Even if you are poor, you are allowed to use the software
included in Skolelinux/Debian Edu and all the other Free Software.&lt;/p&gt;

&lt;p&gt;Second: The software runs on old machines and this gives us the
possibility to recycle computers, weeded out from offices.  The
servers and desktops are running for more than two years and they are
working reliable. &lt;/p&gt;

&lt;p&gt;We have two servers (one tjener and one terminal server), 45
workstations in three classrooms and seven laptops as a mobile
solution for all classrooms.  These machines are all booting from the
terminal server.  In the moment we are installing 30 laptops as mobile
workstations.  Then the pupils have the possibility to work with these
machines in their classrooms.  Internet access is realized by a WLAN
router, connected to the schools network. This is all done without a
dedicated system administrator or a computer science teacher.&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;Teachers and pupils are Windows users.  &amp;lt;Irony on&amp;gt; And Linux
isn&#39;t cool. It&#39;s software for freaks using the command line. &amp;lt;Irony
off&amp;gt; They don&#39;t realize the stability of the system. &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;Firefox, Thunderbird, LibreOffice, Ubuntu Server 12.04 (Samba,
Apache, MySQL, Joomla!, … and Skolelinux / Debian Edu)&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;In Germany we have the situation: every school is free to decide
which software they want to use. This decision is influenced by
teachers who learned to use Windows and MS Office. They buy a PC with
Windows preinstalled and an additional testing version of MS
Office. They don&#39;t know about the possibility to use Free Software
instead.  Another problem are the publisher of school books.  They
develop their software, added to the school books, for Windows.&lt;/p&gt;

                <description>&lt;p&gt;This summer I finally had time to continue working on the Norwegian
&lt;a href=&quot;http://www.docbook.org/&quot;&gt;docbook&lt;/a&gt; version of the 2004 book
&lt;a href=&quot;http://free-culture.cc/&quot;&gt;Free Culture&lt;/a&gt; by Lawrence Lessig,
to get a Norwegian text explaining the problems with todays copyright
law.  Yesterday, I finally completed translated the book text.  There
are still some foot/end notes left to translate, the colophon page
need to be rewritten, and a few words and phrases still need to be
translated, but the Norwegian text is ready for the first proof
reading. :) More spell checking is needed, and several illustrations
need to be cleaned up.  The work stopped up because I had to give
priority to other projects the last year, and the progress graph of
the translation show this very well:&lt;/p&gt;

                <pubDate>Tue, 17 Jun 2014 11:30:00 +0200</pubDate>
                <description>&lt;p&gt;The &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu / Skolelinux
project&lt;/a&gt; provide an instruction manual for teachers, system
administrators and other users that contain useful tips for setting up
and maintaining a Debian Edu installation.  This text is about how the
text processing of this manual is handled in the project.&lt;/p&gt;

&lt;p&gt;One goal of the project is to provide information in the native
language of its users, and for this we need to handle translations.
But we also want to make sure each language contain the same
information, so for this we need a good way to keep the translations
in sync.  And we want it to be easy for our users to improve the
documentation, avoiding the need to learn special formats or tools to
contribute, and the obvious way to do this is to make it possible to
edit the documentation using a web browser.  We also want it to be
easy for translators to keep the translation up to date, and give them
help in figuring out what need to be translated. Here is the list of
tools and the process we have found trying to reach all these
goals.&lt;/p&gt;

&lt;p&gt;We maintain the authoritative source of our manual in the
&lt;a href=&quot;https://wiki.debian.org/DebianEdu/Documentation/Wheezy/&quot;&gt;Debian
wiki&lt;/a&gt;, as several wiki pages written in English.  It consist of one
front page with references to the different chapters, several pages
for each chapter, and finally one &quot;collection page&quot; gluing all the
chapters together into one large web page (aka
&lt;a href=&quot;https://wiki.debian.org/DebianEdu/Documentation/Wheezy/AllInOne&quot;&gt;the
AllInOne page&lt;/a&gt;).  The AllInOne page is the one used for further
processing and translations.  Thanks to the fact that the
&lt;a href=&quot;http://moinmo.in/&quot;&gt;MoinMoin&lt;/a&gt; installation on
wiki.debian.org support exporting pages in
&lt;a href=&quot;http://www.docbook.org/&quot;&gt;the Docbook format&lt;/a&gt;, we can fetch
the list of pages to export using the raw version of the AllInOne
page, loop over each of them to generate a Docbook XML version of the
manual.  This process also download images and transform image
references to use the locally downloaded images.  The generated
Docbook XML files are slightly broken, so some post-processing is done
using the &lt;tt&gt;documentation/scripts/get_manual&lt;/tt&gt; program, and the
result is a nice Docbook XML file (debian-edu-wheezy-manual.xml) and
a handfull of images.  The XML file can now be used to generate PDF, HTML
and epub versions of the English manual.  This is the basic step of
our process, making PDF (using dblatex), HTML (using xsltproc) and
epub (using dbtoepub) version from Docbook XML, and the resulting files
are placed in the debian-edu-doc-en binary package.&lt;/p&gt;

&lt;p&gt;But English documentation is not enough for us.  We want translated
documentation too, and we want to make it easy for translators to
track the English original.  For this we use the
&lt;a href=&quot;http://packages.qa.debian.org/p/poxml.html&quot;&gt;poxml&lt;/a&gt; package,
which allow us to transform the English Docbook XML file into a
translation file (a .pot file), usable with the normal gettext based
translation tools used by those translating free software.  The pot
file is used to create and maintain translation files (several .po
files), which the translations update with the native language
translations of all titles, paragraphs and blocks of text in the
original.  The next step is combining the original English Docbook XML
and the translation file (say debian-edu-wheezy-manual.nb.po), to
create a translated Docbook XML file (in this case
debian-edu-wheezy-manual.nb.xml).  This translated (or partly
translated, if the translation is not complete) Docbook XML file can
then be used like the original to create a PDF, HTML and epub version
of the documentation.&lt;/p&gt;

&lt;p&gt;The translators use different tools to edit the .po files.  We
recommend using
&lt;a href=&quot;http://www.kde.org/applications/development/lokalize/&quot;&gt;lokalize&lt;/a&gt;,
while some use emacs and vi, others can use web based editors like
&lt;a href=&quot;http://pootle.translatehouse.org/&quot;&gt;Poodle&lt;/a&gt; or
&lt;a href=&quot;https://www.transifex.com/&quot;&gt;Transifex&lt;/a&gt;.  All we care about
is where the .po file end up, in our git repository.  Updated
translations can either be committed directly to git, or submitted as
&lt;a href=&quot;https://bugs.debian.org/src:debian-edu-doc&quot;&gt;bug reports
against the debian-edu-doc package&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;One challenge is images, which both might need to be translated (if
they show translated user applications), and are needed in different
formats when creating PDF and HTML versions (epub is a HTML version in
this regard).  For this we transform the original PNG images to the
needed density and format during build, and have a way to provide
translated images by storing translated versions in
images/$LANGUAGECODE/.  I am a bit unsure about the details here.  The
package maintainers know more.&lt;/p&gt;

&lt;p&gt;If you wonder what the result look like, we provide
&lt;a href=&quot;http://maintainer.skolelinux.org/debian-edu-doc/&quot;&gt;the content
of the documentation packages on the web&lt;/a&gt;.  See for example the
&lt;a href=&quot;http://maintainer.skolelinux.org/debian-edu-doc/it/debian-edu-wheezy-manual.pdf&quot;&gt;Italian
PDF version&lt;/a&gt; or the
&lt;a href=&quot;http://maintainer.skolelinux.org/debian-edu-doc/de/debian-edu-wheezy-manual.html&quot;&gt;German
HTML version&lt;/a&gt;.  We do not yet build the epub version by default,
but perhaps it will be done in the future.&lt;/p&gt;

&lt;p&gt;To learn more, check out
&lt;a href=&quot;http://packages.qa.debian.org/d/debian-edu-doc.html&quot;&gt;the
debian-edu-doc package&lt;/a&gt;,

manual on the wiki&lt;/a&gt; and
&lt;a href=&quot;https://wiki.debian.org/DebianEdu/Documentation/Wheezy/Translations&quot;&gt;the
translation instructions&lt;/a&gt; in the manual.&lt;/p&gt;

avspillermetode.  I dag fikk jeg endelig lett etter oppdatert løsning,
og jeg er veldig glad for å fortelle at den enkleste måten å laste ned
innslag er å bruke siste versjon 2014.06.07 av
&lt;a href=&quot;http://rg3.github.io/youtube-dl/&quot;&gt;youtube-dl&lt;/a&gt;.  Støtten i
youtube-dl &lt;a href=&quot;https://github.com/rg3/youtube-dl/issues/2980&quot;&gt;kom
inn for 23 dager siden&lt;/a&gt; og
&lt;a href=&quot;http://packages.qa.debian.org/y/youtube-dl.html&quot;&gt;versjonen i
Debian&lt;/a&gt; fungerer fint også som backport til Debian Wheezy.  Det er
et lite problem, det håndterer kun URLer med små bokstaver, men hvis
en har en URL med store bokstaver kan en bare gjøre alle store om til
små bokstaver for å få youtube-dl til å laste ned.  Rapporterte
nettopp
&lt;a href=&quot;https://github.com/rg3/youtube-dl/issues/2980&quot;&gt;problemet til
utviklerne&lt;/a&gt;, og antar de får fikset det snart.&lt;/p&gt;

&lt;p&gt;Dermed er alt klart til å laste ned dokumentarene om
&lt;a href=&quot;http://tv.nrk.no/program/KOID23005014/usas-hemmelige-avlytting&quot;&gt;USAs
hemmelige avlytting&lt;/a&gt; og
&lt;a href=&quot;http://tv.nrk.no/program/KOID23005114/selskapene-bak-usas-avlytting&quot;&gt;Selskapene
bak USAs avlytting&lt;/a&gt;, i tillegg til
&lt;a href=&quot;http://tv.nrk.no/program/KOID20005814/et-moete-med-edward-snowden&quot;&gt;intervjuet
med Edward Snowden gjort av den tyske tv-kanalen ARD&lt;/a&gt;.  Anbefaler
alle å se disse, sammen med
&lt;a href=&quot;http://media.ccc.de/browse/congress/2013/30C3_-_5713_-_en_-_saal_2_-_201312301130_-_to_protect_and_infect_part_2_-_jacob.html&quot;&gt;foredraget
til Jacob Appelbaum på siste CCC-konferanse&lt;/a&gt;, for å forstå mer om
hvordan overvåkningen av borgerne brer om seg.&lt;/p&gt;

&lt;p&gt;Takk til gode venner på foreningen NUUGs IRC-kanal
&lt;a href=&quot;irc://irc.freenode.net/%23nuug&quot;&gt;#nuug på irc.freenode.net&lt;/a&gt;
for tipsene som fikk meg i mål&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Oppdatering 2014-06-17&lt;/strong&gt;: Etter at jeg publiserte
denne, ble jeg tipset om bloggposten
&quot;&lt;a href=&quot;http://ingvar.blog.redpill-linpro.com/2012/05/31/downloading-hd-content-from-tv-nrk-no/&quot;&gt;Downloading
HD content from tv.nrk.no&lt;/a&gt;&quot; av Ingvar Hagelund, som har alternativ
implementasjon og tips for å lage mkv-fil med undertekstene inkludert.
Kanskje den passer bedre for deg?  I tillegg ble feilen i youtube-dl
ble fikset litt senere ut på dagen i går, samt at youtube-dl fikk
støtte for å laste ned undertitler.  Takk til Anders Einar Hilden for
god innsats og youtube-dl-utviklerne for rask respons.&lt;/p&gt;

                <title>Free software car computer solution?</title>

                <pubDate>Thu, 29 May 2014 18:45:00 +0200</pubDate>
                <description>&lt;p&gt;Dear lazyweb.  I&#39;m planning to set up a small Raspberry Pi computer
in my car, connected to
&lt;a href=&quot;http://www.dx.com/p/400a-4-0-tft-lcd-digital-monitor-for-vehicle-parking-reverse-camera-1440x272-12v-dc-57776&quot;&gt;a
small screen&lt;/a&gt; next to the rear mirror.  I plan to hook it up with a
GPS and a USB wifi card too.  The idea is to get my own
&quot;&lt;a href=&quot;http://en.wikipedia.org/wiki/Carputer&quot;&gt;Carputer&lt;/a&gt;&quot;.  But I
wonder if someone already created a good free software solution for
such car computer.&lt;/p&gt;

&lt;p&gt;This is my current wish list for such system:&lt;/p&gt;

&lt;ul&gt;

 &lt;li&gt;Work on Raspberry Pi.&lt;/li&gt;

 &lt;li&gt;Show current speed limit based on location, and warn if going too
   fast (for example using color codes yellow and red on the screen,
   or make a sound).  This could be done either using either data from
   &lt;a href=&quot;http://www.openstreetmap.org/&quot;&gt;Openstreetmap&lt;/a&gt; or OCR
   info gathered from a dashboard camera.&lt;/li&gt;

 &lt;li&gt;Track automatic toll road passes and their cost, show total spent
   and make it possible to calculate toll costs for planned
   route.&lt;/li&gt;

 &lt;li&gt;Collect GPX tracks for use with OpenStreetMap.&lt;/li&gt;

 &lt;li&gt;Automatically detect and use any wireless connection to connect
   to home server.  Try IP over DNS
   (&lt;a href=&quot;http://dev.kryo.se/iodine/&quot;&gt;iodine&lt;/a&gt;) or ICMP
   (&lt;a href=&quot;http://code.gerade.org/hans/&quot;&gt;Hans&lt;/a&gt;) if direct
   connection do not work.&lt;/li&gt;

 &lt;li&gt;Set up mesh network to talk to other cars with the same system,
   or some standard car mesh protocol.&lt;/li&gt;

 &lt;li&gt;Warn when approaching speed cameras and speed camera ranges
   (speed calculated between two cameras).&lt;/li&gt;

 &lt;li&gt;Suport dashboard/front facing camera to discover speed limits and
   run OCR to track registration number of passing cars.&lt;/li&gt;

&lt;/ul&gt;

&lt;p&gt;If you know of any free software car computer system supporting
some or all of these features, please let me know.&lt;/p&gt;

                <title>Half the Coverity issues in Gnash fixed in the next release</title>
                <link>http://people.skolelinux.org/pere/blog/Half_the_Coverity_issues_in_Gnash_fixed_in_the_next_release.html</link>
                <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Half_the_Coverity_issues_in_Gnash_fixed_in_the_next_release.html</guid>
                <pubDate>Tue, 29 Apr 2014 14:20:00 +0200</pubDate>
                <description>&lt;p&gt;I&#39;ve been following &lt;a href=&quot;http://www.getgnash.org/&quot;&gt;the Gnash
project&lt;/a&gt; for quite a while now.  It is a free software
implementation of Adobe Flash, both a standalone player and a browser
plugin.  Gnash implement support for the AVM1 format (and not the
newer AVM2 format - see
&lt;a href=&quot;http://lightspark.github.io/&quot;&gt;Lightspark&lt;/a&gt; for that one),
allowing several flash based sites to work.  Thanks to the friendly
developers at Youtube, it also work with Youtube videos, because the
Javascript code at Youtube detect Gnash and serve a AVM1 player to
those users. :) Would be great if someone found time to implement AVM2
support, but it has not happened yet.  If you install both Lightspark
and Gnash, Lightspark will invoke Gnash if it find a AVM1 flash file,
so you can get both handled as free software.  Unfortunately,
Lightspark so far only implement a small subset of AVM2, and many
sites do not work yet.&lt;/p&gt;

&lt;p&gt;A few months ago, I started looking at
&lt;a href=&quot;http://scan.coverity.com/&quot;&gt;Coverity&lt;/a&gt;, the static source
checker used to find heaps and heaps of bugs in free software (thanks
to the donation of a scanning service to free software projects by the
company developing this non-free code checker), and Gnash was one of
the projects I decided to check out.  Coverity is able to find lock
errors, memory errors, dead code and more.  A few days ago they even
extended it to also be able to find the heartbleed bug in OpenSSL.
There are heaps of checks being done on the instrumented code, and the
amount of bogus warnings is quite low compared to the other static
code checkers I have tested over the years.&lt;/p&gt;

&lt;p&gt;Since a few weeks ago, I&#39;ve been working with the other Gnash
developers squashing bugs discovered by Coverity.  I was quite happy
today when I checked the current status and saw that of the 777 issues
detected so far, 374 are marked as fixed.  This make me confident that
the next Gnash release will be more stable and more dependable than
the previous one.  Most of the reported issues were and are in the
test suite, but it also found a few in the rest of the code.&lt;/p&gt;

&lt;p&gt;If you want to help out, you find us on
&lt;a href=&quot;https://lists.gnu.org/mailman/listinfo/gnash-dev&quot;&gt;the
gnash-dev mailing list&lt;/a&gt; and on
&lt;a href=&quot;irc://irc.freenode.net/#gnash&quot;&gt;the #gnash channel on
irc.freenode.net IRC server&lt;/a&gt;.&lt;/p&gt;
