- <description><p>Behind <a href="http://www.skolelinux.org/">Debian Edu and
-Skolelinux</a> there are a lot of people doing the hard work of
-setting together all the pieces. This time I present to you Andreas
-Mundt, who have been part of the technical development team several
-years. He was also a key contributor in getting GOsa and Kerberos set
-up in the recently released
-<a href="http://wiki.debian.org/DebianEdu/Documentation/Squeeze">Debian
-Edu Squeeze</a> version.</p>
-
-<p><strong>Who are you, and how do you spend your days?</strong></p>
-
-<p>My name is Andreas Mundt, I grew up in south Germany. After
-studying Physics I spent several years at university doing research in
-Quantum Optics. After that I worked some years in an optics company.
-Finally I decided to turn over a new leaf in my life and started
-teaching 10 to 19 years old kids at school. I teach math, physics,
-information technology and science/technology.</p>
-
-<p><strong>How did you get in contact with the Skolelinux/Debian Edu
-project?</strong></p>
-
-<p>Already before I switched to teaching, I followed the Debian Edu
-project because of my interest in education and Debian. Within the
-qualification/training period for the teaching, I started
-contributing.</p>
-
-<p><strong>What do you see as the advantages of Skolelinux/Debian
-Edu?</strong></p>
-
-<p>The advantages of Debian Edu are the well known name, the
-out-of-the-box philosophy and of course the great free software of the
-Debian Project!</p>
-
-<p><strong>What do you see as the disadvantages of Skolelinux/Debian
-Edu?</strong></p>
-
-<p>As every coin has two sides, the out-of-the-box philosophy has its
-downside, too. In my opinion, it is hard to modify and tweak the
-setup, if you need or want that. Further more, it is not easily
-possible to upgrade the system to a new release. It takes much too
-long after a Debian release to prepare the -Edu release, perhaps
-because the number of developers working on the core of the code is
-rather small and often busy elsewhere.</p>
-
-<p>The <a href="http://wiki.debian.org/DebianLAN">Debian LAN</a>
-project might fill the use case of a more flexible system.</p>
-
-<p><strong>Which free software do you use daily?</strong></p>
-
-<p>I am only using non-free software if I am forced to and run Debian
-on all my machines. For documents I prefer LaTeX and PGF/TikZ, then
-mutt and iceweasel for email respectively web browsing. At school I
-have Arduino and Fritzing in use for a micro controller project.</p>
-
-<p><strong>Which strategy do you believe is the right one to use to
-get schools to use free software?</strong></p>
-
-<p>One of the major problems is the vendor lock-in from top to bottom:
-Especially in combination with ignorant government employees and
-politicians, this works out great for the "market-leader". The school
-administration here in Baden-Wuerttemberg is occupied by that vendor.
-Documents have to be prepared in non-free, proprietary formats. Even
-free browsers do not work for the school administration. Publishers
-of school books provide software only for proprietary platforms.</p>
-
-<p>To change this, political work is very important. Parts of the
-political spectrum have become aware of the problem in the last years.
-However it takes quite some time and courageous politicians to 'free'
-the system. There is currently some discussion about "Open Data" and
-"Free/Open Standards". I am not sure if all the involved parties have
-a clue about the potential of these ideas, and probably only a
-fraction takes them seriously. However it might slowly make free
-software and the philosophy behind it more known and popular.</p>

- <description><p>It take all kind of contributions to create a Linux distribution
-like <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a>,
-and this time I lend the ear to Justin B. Rye, who is listed as a big
-contributor to the
-<a href="http://wiki.debian.org/DebianEdu/Documentation/Squeeze">Debian
-Edu Squeeze release manual</a>.
-
-<p><strong>Who are you, and how do you spend your days?</strong></p>
-
-<p>I'm a 44-year-old linguistics graduate living in Edinburgh who has
-occasionally been employed as a sysadmin.</p>
-
-<p><strong>How did you get in contact with the Skolelinux/Debian Edu
-project?</strong></p>
-
-<p>I'm neither a developer nor a Skolelinux/Debian Edu user! The only
-reason my name's in the credits for the documentation is that I hang
-around on debian-l10n-english waiting for people to mention things
-they'd like a native English speaker to proofread... So I did a sweep
-through the wiki for typos and Norglish and inconsistent spellings of
-"localisation".</p>
-
-<p><strong>What do you see as the advantages of Skolelinux/Debian
-Edu?</strong></p>
-
-<p><strong>What do you see as the disadvantages of Skolelinux/Debian
-Edu?</strong></p>
-
-<p>These questions are too hard for me - I don't use it! In fact I
-had hardly any contact with I.T. until long after I'd got out of the
-education system.</p>
-
-<p>I can tell you the advantages of Debian for me though: it soaks up
-as much of my free time as I want and no more, and lets me do
-everything I want a computer for without ever forcing me to spend
-money on the latest hardware.</p>
-
-<p><strong>Which free software do you use daily?</strong></p>
-
-<p>I've been using Debian since Rex; popularity-contest says the
-software that I use most is xinit, xterm, and xulrunner (in other
-words, I use a distinctly retro sort of desktop).</p>
-
-<p><strong>Which strategy do you believe is the right one to use to
-get schools to use free software?</strong></p>
-
-<p>Well, I don't know. I suppose I'd be inclined to try reasoning
-with the people who make the decisions, but obviously if that worked
-you would hardly need a strategy.</p>

- <title>Why the KDE menu is slow when /usr/ is NFS mounted - and a workaround</title>

- <description><p>Recently I have spent time with
-<a href="http://www.slxdrift.no/">Skolelinux Drift AS</a> on speeding
-up a <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a>
-Lenny installation using LTSP diskless workstations, and in the
-process I discovered something very surprising. The reason the KDE
-menu was responding slow when using it for the first time, was mostly
-due to the way KDE find application icons. I discovered that showing
-the Multimedia menu would cause more than 20 000 IP packages to be
-passed between the LTSP client and the NFS server. Most of these were
-
-NFS LOOKUP calls, resulting in a NFS3ERR_NOENT response. Because the
-ping times between the client and the server were in the range 2-20
-ms, the menus would be very slow. Looking at the strace of kicker in
-Lenny (or plasma-desktop i Squeeze - same problem there), I see that
-the source of these NFS calls are access(2) system calls for
-non-existing files. KDE can do hundreds of access(2) calls to find
-one icon file. In my example, just finding the mplayer icon required
-around 230 access(2) calls.</p>
-
-<p>The KDE code seem to search for icons using a list of icon
-directories, and the list of possible directories is large. In
-(almost) each directory, it look for files ending in .png, .svgz, .svg
-and .xpm. The result is a very slow KDE menu when /usr/ is NFS
-mounted. Showing a single sub menu may result in thousands of NFS
-requests. I am not the first one to discover this. I found a
-<a href="https://bugs.kde.org/show_bug.cgi?id=211416">KDE bug report
-from 2009</a> about this problem, and it is still unsolved.</p>
-
-<p>My solution to speed up the KDE menu was to create a package
-kde-icon-cache that upon installation will look at all .desktop files
-used to generate the KDE menu, find their icons, search the icon paths
-for the file that KDE will end up finding at run time, and copying the
-icon file to /var/lib/kde-icon-cache/. Finally, I add symlinks to
-these icon files in one of the first directories where KDE will look
-for them. This cut down the number of file accesses required to find
-one icon from several hundred to less than 5, and make the KDE menu
-almost instantaneous. I'm not quite sure where to make the package
-publicly available, so for now it is only available on request.</p>
-
-<p>The bug report mention that this do not only affect the KDE menu
-and icon handling, but also the login process. Not quite sure how to
-speed up that part without replacing NFS with for example NBD, and
-that is not really an option at the moment.</p>
-
-<p>If you got feedback on this issue, please let us know on debian-edu
-(at) lists.debian.org.</p>

- <pubDate>Sun, 1 Apr 2012 23:00:00 +0200</pubDate>
- <description><p>Germany is a core area for the
-<a href="http://www.skolelinux.org/">Debian Edu and Skolelinux</a>
-user community, and this time I managed to get hold of Wolfgang
-Schweer, a valuable contributor to the project from Germany.
-
-<p><strong>Who are you, and how do you spend your days?</strong></p>
-
-<p>I've studied Mathematics at the university 'Ruhr-Universität' in
-Bochum, Germany. Since 1981 I'm working as a teacher at the school
-"<a href="http://www.westfalenkolleg-dortmund.de/">Westfalen-Kolleg
-Dortmund</a>", a second chance school. Here, young adults is given
-the opportunity to get further education in order to do the school
-examination 'Abitur', which will allow to study at a university. This
-second chance is of value for those who want a better job perspective
-or failed to get a higher school examination being teens.</p>
-
-<p>Besides teaching I was involved in developing online courses for a
-blended learning project called 'abitur-online.nrw' and in some other
-information technology related projects. For about ten years I've been
-teacher and coordinator for the 'abitur-online' project at my
-school. Being now in my early sixties, I've decided to leave school at
-the end of April this year.</p>
-
-<p><strong>How did you get in contact with the Skolelinux/Debian Edu
-project?</strong></p>
-
-<p>The first information about Skolelinux must have come to my
-attention years ago and somehow related to LTSP (Linux Terminal Server
-Project). At school, we had set up a network at the beginning of 1997
-using Suse Linux on the desktop, replacing a Novell network. Since
-2002, we used old machines from the city council of Dortmund as thin
-clients (LTSP, later Ubuntu/Lessdisks) cause new hardware was out of
-reach. At home I'm using Debian since years and - subscribed to the
-Debian news letter - heard from time to time about Skolelinux. About
-two years ago I proposed to replace the (somehow undocumented and only
-known to me) system at school by a well known Debian based system:
-Skolelinux.</p>
-
-<p>Students and teachers appreciated the new system because of a
-better look and feel and an enhanced access to local media on thin
-clients. The possibility to alter and/or reset passwords using a GUI
-was welcomed, too. Being able to do administrative tasks using a GUI
-and to easily set up workstations using PXE was of very high value for
-the admin teachers.</p>
-
-<p><strong>What do you see as the advantages of Skolelinux/Debian
-Edu?</strong></p>
-
-<p>It's open source, easy to set up, stable and flexible due to it's
-Debian base. It integrates LTSP out-of-the-box. And it is documented!
-So it was a perfect choice.</p>
-
-<p>Being open source, there are no license problems and so it's
-possible to point teachers and students to programs like
-OpenOffice.org, ViewYourMind (mind mapping) and The Gimp. It's of
-high value to be able to adapt parts of the system to special needs of
-a school and to choose where to get support for this.</p>
-
-<p><strong>What do you see as the disadvantages of Skolelinux/Debian
-Edu?</strong></p>
-
-<p>Nothing yet.</p>
-
-<p><strong>Which free software do you use daily?</strong></p>
-
-<p>At home (Debian Sid with Gnome Desktop): Iceweasel, LibreOffice,
-Mutt, Gedit, Document Viewer, Midnight Commander, flpsed (PDF
-Annotator). At school (Skolelinux Lenny): Iceweasel, Gedit,
-LibreOffice.</p>
-
-<p><strong>Which strategy do you believe is the right one to use to
-get schools to use free software?</strong></p>
-
-<p>Some time ago I thought it was enough to tell people about it. But
-that doesn't seem to work quite well. Now I concentrate on those more
-interested and hope to get multiplicators that way.</p>
