- <div class="date">10th September 2014</div>
- <div class="body"><p>Yesterday, I had the pleasure of attending a talk with the
-<a href="http://www.nuug.no/">Norwegian Unix User Group</a> about
-<a href="http://www.nuug.no/aktiviteter/20140909-sks-keyservers/">the
-OpenPGP keyserver pool sks-keyservers.net</a>, 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.</p>
-
-<p>Behind the round robin DNS entry of the
-<a href="https://sks-keyservers.net/">sks-keyservers.net</a> 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. :)</p>
-
-<p>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?</p>
-
-<p>Anyway, I've updated my ~/.gnupg/options file to now include this
-line:</p>
-
-<p><blockquote><pre>
-keyserver pool.sks-keyservers.net
-</pre></blockquote></p>
-
-<p>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:</p>
-
-<p><blockquote><pre>
-% host -t srv _pgpkey-http._tcp.uio.no
-_pgpkey-http._tcp.uio.no has SRV record 0 100 11371 pool.sks-keyservers.net.
-%
-</pre></blockquote></p>
-
-<p>Now if only
-<a href="http://ietfreport.isoc.org/idref/draft-shaw-openpgp-hkp/">the
-HKP lookup protocol</a> 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?</p>

+ <div class="date"> 1st May 2015</div>
+ <div class="body"><p>Many years ago, a friend of mine calculated how much it would cost
+to store the sound of all phone calls in Norway, and came up with the
+cost of around 20 million NOK (2.4 mill EUR) for all the calls in a
+year. I got curious and wondered what the same calculation would look
+like today. To do so one need an idea of how much data storage is
+needed for each minute of sound, how many minutes all the calls in
+Norway sums up to, and the cost of data storage.</p>
+
+<p>The 2005 numbers are from
+<a href="http://www.digi.no/analyser/2005/10/04/vi-prater-stadig-mindre-i-roret">digi.no</a>,
+the 2012 numbers are from
+<a href="http://www.nkom.no/aktuelt/nyheter/fortsatt-vekst-i-det-norske-ekommarkedet">a
+NKOM report</a>, and I got the 2013 numbers after asking NKOM via
+email. I was told the numbers for 2014 will be presented May 20th,
+and decided not to wait for those, as I doubt they will be very
+different from the numbers from 2013.</p>
+
+<p>The amount of data storage per minute sound depend on the wanted
+quality, and for phone calls it is generally believed that 8 Kbit/s is
+enough. See for example a
+<a href="http://www.cisco.com/c/en/us/support/docs/voice/voice-quality/7934-bwidth-consume.html#topic1">summary
+on voice quality from Cisco</a> for some alternatives. 8 Kbit/s is 60
+Kbytes/min, and this can be multiplied with the number of call minutes
+to get the storage requirements.</p>
+
+<p>Storage prices varies a lot, depending on speed, backup strategies,
+availability requirements etc. But a simple way to calculate can be
+to use the price of a TiB-disk (around 1000 NOK / 120 EUR) and double
+it to take space, power and redundancy into account. It could be much
+higher with high speed and good redundancy requirements.</p>
+
+<p>But back to the question, What would it cost to store all phone
+calls in Norway? Not much. Here is a small table showing the
+estimated cost, which is within the budget constraint of most medium
+and large organisations:</p>
+
+<table border="1">
+<tr><th>Year</th><th>Call minutes</th><th>Size</th><th>Price in NOK / EUR</th></tr>
+<tr><td>2005</td><td align="right">24 000 000 000</td><td align="right">1.3 PiB</td><td align="right">3 mill / 358 000</td></tr>
+<tr><td>2012</td><td align="right">18 000 000 000</td><td align="right">1.0 PiB</td><td align="right">2.2 mill / 262 000</td></tr>
+<tr><td>2013</td><td align="right">17 000 000 000</td><td align="right">950 TiB</td><td align="right">2.1 mill / 250 000</td></tr>
+</table>
+
+<p>This is the cost of buying the storage. Maintenance need to be
+taken into account too, but calculating that is left as an exercise
+for the reader. But it is obvious to me from those numbers that
+recording the sound of all phone calls in Norway is not going to be
+stopped because it is too expensive. I wonder if someone already is
+collecting the data?</p>

- <div class="date">25th August 2014</div>
- <div class="body"><p>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

+(As most reading this will know, Debian "Jessie" hasn't actually been
+released by now. The release is still in progress but should finish
+later today ;)
+
+We expect to make a final release of Debian Edu "Jessie" in the coming
+weeks, timed with the first point release of Debian Jessie. Upgrades
+from this beta release of Debian Edu Jessie to the final release will
+be possible and encouraged!
+
+Please report feedback to debian-edu@lists.debian.org and/or submit
+bugs: http://wiki.debian.org/DebianEdu/HowTo/ReportBugs
+
+Debian Edu - sometimes also known as "Skolelinux" - is a complete
+operating system for schools, universities and other
+organisations. Through its pre- prepared installation profiles
+administrators can install servers, workstations and laptops which
+will work in harmony on the school network. With Debian Edu, the
+teachers themselves or their technical support staff can roll out a
+complete multi-user, multi-machine study environment within hours or
+days.
+
+Debian Edu is already in use at several hundred schools all over the
+world, particularly in Germany, Spain and Norway. Installations come
+with hundreds of applications pre-installed, plus the whole Debian
+archive of thousands of compatible packages within easy reach.
+
+For those who want to give Debian Edu Jessie a try, download and
+installation instructions are available, including detailed
+instructions in the manual 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!

+== About Debian Edu / Skolelinux ==
+
+Debian Edu, also known as Skolelinux, is a Linux distribution based on
+Debian providing an out-of-the box environment of a completely
+configured school network. Directly 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 and more are available from the Debian archive, and schools
+can choose between KDE, GNOME, LXDE, Xfce and MATE desktop
+environment.
+
+== About Debian ==
+
+The Debian Project was founded in 1993 by Ian Murdock to be a truly
+free community project. Since then the project has grown to be one of
+the largest and most influential open source projects. Thousands of
+volunteers from all over the world work together to create and
+maintain Debian software. Available in 70 languages, and supporting a
+huge range of computer types, Debian calls itself the universal
+operating system.
+
+== Thanks ==
+
+Thanks to everyone making Debian and Debian Edu / Skolelinux happen!
+You rock.

- <div class="date">31st July 2014</div>
- <div class="body"><p>The complete and free “out of the box” software solution for
-schools, <a href="http://www.skolelinux.org/">Debian Edu /
-Skolelinux</a>, 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.</p>
+ <div class="title"><a href="http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Shirish_Agarwal.html">Debian Edu interview: Shirish Agarwal</a></div>
+ <div class="date">15th April 2015</div>
+ <div class="body"><p>It was a surprise to me to learn that project to create a complete
+computer system for schools I've involved in,
+<a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a>, was
+being used in India. But apparently it is, and I managed to get an
+interview with one of the friends of the project there, Shirish
+Agarwal.</p>
<p><strong>Who are you, and how do you spend your days?</strong></p>
-<p>My name is Bernd Zeitzen and I'm married with Hedda, a self
-employed physiotherapist. My former profession is tool maker, but I
-haven'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 . :-(</p>
-
-<p>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.</p>
+<p>My name is Shirish Agarwal. Based out of the educational and
+historical city of Pune, from the western state of Maharashtra, India.
+My bread comes from giving training, giving policy tips,
+installations on free software to mom and pop shops in different
+fields from Desktop publishing to retail shops as well as work with
+few software start-ups as well.</p>
<p><strong>How did you get in contact with the Skolelinux / Debian Edu
project?</strong></p>
-<p>Two years ago a friend of mine asked me, if I want to get a job in
-his school (<a href="http://www.gymnasium-harsewinkel.de/">Gymnasium
-Harsewinkel</a>). 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'm spending 4-6 hours a week
-with this job.</p>
+<p>It started innocently enough. I have been using Debian for a few
+years and in one local minidebconf / debutsav I was asked if there was
+anything for schools or education. I had worked / played with free
+educational softwares such as Gcompris and Stellarium for my many
+nieces and nephews so researched and found Debian Edu or Skolelinux as
+it was known then. Since then I have started using the various
+education meta-packages provided by the project.</p>
<p><strong>What do you see as the advantages of Skolelinux / Debian
Edu?</strong></p>
-<p>The independence.</p>
-
-<p>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.</p>
-
-<p>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. </p>
-
-<p>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.</p>
+<p>It's closest I have seen where a package full of educational
+software are packed, which are free and open (both literally and
+figuratively). Even if I take the simplest software which is
+gcompris, the number of activities therein are amazing. Another one of
+the softwares that I have liked for a long time is stellarium. Even
+pysycache is cool except for couple of issues I encountered
+<a href="https://bugs.debian.org/781841">#781841</a> and
+<a href="https://bugs.debian.org/781842">#781842</a>.</p>
+
+<p>I prefer software installed on the system over web based solutions,
+as a web site can disappear any time but the software on disk has the
+possibility of a larger life span. Of course with both it's more a
+question if it has enough users who make it fun or sustainable or both
+for the developer per-se.</p>
<p><strong>What do you see as the disadvantages of Skolelinux / Debian
Edu?</strong></p>
-<p>Teachers and pupils are Windows users. <Irony on> And Linux
-isn't cool. It's software for freaks using the command line. <Irony
-off> They don't realize the stability of the system. </p>
+<p>I do see that the Debian Edu team seems to be short-handed and I
+think more efforts should be made to make it popular and ask and take
+help from people and the larger community wherever possible.</p>
+
+<p>I don't see any disadvantage to use Skolelinux apart from the fact
+that most apps. are generic which is good or bad how you see it.
+However, saying that I do acknowledge the fact that the canvas is
+pretty big and there are lot of interesting ideas that could be done
+but for reasons not known not done or if done I don't know about them.
+Let me share some of the ideas (these are more upstream based but
+still) I have had for a long time :</p>
+
+<p>1. Classical maths question of two trains in opposing directions
+each running @x kmph/mph at y distance, when they will meet and how
+far would each travel and similar questions like these.
+
+<p>The computer is a fantastic system where questions like these can
+be drawn, animated and the methodology and answers teased out in
+interactive manner. While sites such as the
+<a href="http://mathforum.org/dr.math/faq/faq.two.trains.html">Ask
+Dr. Math FAQ on The Two Trains problem</a> (as an example or point of
+inspiration) can be used there is lot more that can be done. I dunno
+if there is a free software which does something like this. The idea
+being a blend of objects + animation + interaction which does
+this. The whole interaction could be gamified with points or sounds or
+colourful celebration whenever the user gets even part of the question
+or/and methodology right. That would help reinforce good behaviour.
+This understanding could be used to share/showcase everything from how
+the first wheel came to be, to evolution to how astronomy started,
+psychics and everything in-between.</p>
+
+<p>One specific idea in the train part was having the Linux mascot on
+one train and the BSD or GNU mascot on the other train and they
+meeting somewhere in-between. Characters from blender movies could
+also be used.</p>
+
+<p>2. Loads of crossword-puzzles with reference to subjects: We have
+enormous data sets in Wikipedia and Wikitionary. I don't think it
+should be a big job to design crossword puzzles. Using categories and
+sub-categories it should be doable to have Q&A single word answers
+from the existing data-sets. What would make it easy or hard could be
+the length of the word + existence of many or few vowels depending on
+the user's input.</p>
+
+<p>3. Jigsaw puzzles - We already have a great software called
+palapeli with number of slicers making it pretty interesting. What
+needs to be done is to download large number of public domain and
+copyleft images, tease and use IPTC tags to categorise them into
+nature, history etc. and let it loose. This could turn to be really
+huge collection of images. One source could be taken from
+commons.wikimedia.org, others could be huge collection of royalty-free
+stock photos. Potential is immense.</p>
+
+<p>Apart from this, free software suffers in two directions, we lag
+both in development (of using new features per-se) and maintenance a
+lot. This is more so in educational software as these applications
+need to be timely and the opportunity cost of missing deadlines is
+immense. If we are able to solve issues of funding for development and
+maintenance of such software I don't see any big difficulties. I know
+of few start-ups in and around India who would love to develop and
+maintain such software if funding issues could be solved.</p>
<p><strong>Which free software do you use daily?</strong></p>
-<p>Firefox, Thunderbird, LibreOffice, Ubuntu Server 12.04 (Samba,
-Apache, MySQL, Joomla!, … and Skolelinux / Debian Edu)</p>
+<p>That would be huge list. Some of the softwares are obviously apt,
+aptitude, debdelta, leafpad, the shell of course (zsh nowadays),
+quassel for IRC. In games I use shisen-sho while card-games are evenly
+between kpat and Aiselriot. In desktops it's a tie between
+gnome-flashback and mate.</p>
<p><strong>Which strategy do you believe is the right one to use to
get schools to use free software?</strong></p>
-<p>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'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.</p>
+<p>I think it should first start with using specific FOSS apps. in
+whatever environment they are. If it's MS-Windows or Mac so be it.
+Once they are habitual with the apps. and there is buy-in from the
+school management then it could be installed anywhere. Most of the
+people now understand the concept of a repository because of the
+various online stores so it isn't hard to convince on that front.</p>
+
+<p>What is harder is having enough people with technical skills and
+passion to service them. If you get buy-in from one or two teachers
+then ideas like above could also be asked to be done as a project as
+well.</p>
+
+<p>I think where we fall short more than anything is in marketing. For
+instance, Debian has this whole range of fonts in its archive but
+there isn't even a page where all those different fonts in the La
+Ipsum format could be tried out for newcomers.</p>
+
+<p>One of the issues faced constantly in installations is with updates
+and upgrades. People have this myth that each update and upgrade
+means the user interface will / has to change. I have seen this
+innumerable times. That perhaps is one of the reasons which browsers
+like Iceweasel / Firefox change user interfaces so much, not because
+it might be needed or be functional but because people believe that
+changed user interfaces are better. This, can easily be pointed with
+the user interfaces changed with almost every MS-Windows and Mac OS
+releases.</p>
+
+<p>The problems with Debian Edu for deployment are many. The biggest
+is the huge gap between what is taught in schools and what Debian Edu
+is aimed at.
+
+<p>Me and my friends did teach on week-ends in a government school for
+around 2 years, and
+<a href="https://flossexperiences.wordpress.com/2012/10/08/sharings/">gathered
+some experience</a> there. Some of the things we learnt/discovered
+there was :</p>
+
+<ol>
+
+ <li>Most of the teachers are very territorial about their subjects
+ and they do not want you to teach anything out of the
+ portion/syllabus given.</li>
+
+ <li>They want any activity on the system in accordance to whatever
+ is in the syllabus.</li>
+
+ <li>There are huge barriers both with the English language and at
+ times with objects or whatever. An example, let's say in gcompris
+ you have objects falling down and you have to name them and let's
+ say the falling object is a hat or a fedora hat, this would not be
+ as recognizable as say a
+ <a href="https://en.wikipedia.org/wiki/Puneri_Pagadi">Puneri
+ Pagdi</a> so there is need to inject local objects, words wherever
+ possible. Especially for word-games there are so many hindi words
+ which have become part of english vocabulary (for instance in
+ parley), those could be made into a hinglish collection or
+ something but that is something for upstream to do.</li>
+
+</ol>

-project</a> 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.</p>
-
-<p>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.</p>
-
-<p>We maintain the authoritative source of our manual in the
-<a href="https://wiki.debian.org/DebianEdu/Documentation/Wheezy/">Debian
-wiki</a>, 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 "collection page" gluing all the
-chapters together into one large web page (aka
-<a href="https://wiki.debian.org/DebianEdu/Documentation/Wheezy/AllInOne">the
-AllInOne page</a>). The AllInOne page is the one used for further
-processing and translations. Thanks to the fact that the
-<a href="http://moinmo.in/">MoinMoin</a> installation on
-wiki.debian.org support exporting pages in
-<a href="http://www.docbook.org/">the Docbook format</a>, 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 <tt>documentation/scripts/get_manual</tt> 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.</p>
-
-<p>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
-<a href="http://packages.qa.debian.org/p/poxml.html">poxml</a> 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.</p>
-
-<p>The translators use different tools to edit the .po files. We
-recommend using
-<a href="http://www.kde.org/applications/development/lokalize/">lokalize</a>,
-while some use emacs and vi, others can use web based editors like
-<a href="http://pootle.translatehouse.org/">Poodle</a> or
-<a href="https://www.transifex.com/">Transifex</a>. 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
-<a href="https://bugs.debian.org/src:debian-edu-doc">bug reports
-against the debian-edu-doc package</a>.</p>
-
-<p>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.</p>
-
-<p>If you wonder what the result look like, we provide
-<a href="http://maintainer.skolelinux.org/debian-edu-doc/">the content
-of the documentation packages on the web</a>. See for example the
-<a href="http://maintainer.skolelinux.org/debian-edu-doc/it/debian-edu-wheezy-manual.pdf">Italian
-PDF version</a> or the
-<a href="http://maintainer.skolelinux.org/debian-edu-doc/de/debian-edu-wheezy-manual.html">German
-HTML version</a>. We do not yet build the epub version by default,
-but perhaps it will be done in the future.</p>

+where I am a member, and where people interested in free software,
+open standards and UNIX like operating systems like Linux and the BSDs
+come together, record our monthly technical presentations on video.
+The purpose is to document the talks and spread them to a wider
+audience. For this, the the Norwegian nationwide open channel
+<a href="http://www.frikanalen.no/">Frikanalen</a> is a useful venue.
+Since a few days ago, when I figured out the
+<a href="http://beta.frikanalen.no/api/">REST API</a> to program the
+<a href="http://beta.frikanalen.tv/guide/">channel time schedule</a>,
+the channel has been filled with NUUG talks, related recordings and
+some Creative Commons licensed TED talks (from archive.org). I fill
+all "leftover bits" on the channel with content from NUUG, which at
+the moment is almost 17 of 24 hours every day.</p>
+
+<p>The list of NUUG videos
+<a href="http://beta.frikanalen.tv/organization/82">uploaded so far</a>
+include things like a
+<a href="http://beta.frikanalen.tv/video/625090">one hour talk by John
+Perry Barlow when he visited Oslo</a>, a presentation of
+<a href="http://beta.frikanalen.tv/video/624275">Haiku, the BeOS
+re-implementation</a>, the
+<a href="http://beta.frikanalen.tv/video/624493">history of FiksGataMi,
+the Norwegian version of FixMyStreet</a>, the good old
+<a href="http://beta.frikanalen.tv/video/623566">Warriors of the net
+video</A> and many others.</p>
+
+<p>We have a large backlog of NUUG talks not yet uploaded to
+Frikanalen, and plan to upload every useful bit to the channel to
+spread the word there. I also hope to find useful recordings from the
+Chaos Computer Club and Debian conferences and spread them on the
+channel as well. But this require locating the videos and their meta
+information (title, description, license, etc), and preparing the
+recordings for broadcast, and I have not yet had the spare time to
+focus on this. Perhaps you want to help. Please join us on IRC,
+<a href="irc://irc.freenode.net/%23nuug">#nuug on irc.freenode.net</a>
+if you want to help make this happen.</p>
+
+<p>But as I said, already the channel is already almost exclusively
+filled with technical topics, and if you want to learn something new
+today, check out the <a href="http://www.frikanalen.tv/se">Ogg Theora
+web stream</a> or use one of the other ways to get access to the
+channel. Unfortunately the Ogg Theora recoding for distribution still
+do not properly sync the video and sound. It is generated by recoding
+a internal MPEG transport stream with MPEG4 coded video (ie H.264) to
+Ogg Theora / Vorbis, and we have not been able to find a way that
+produces acceptable quality. Help needed, please get in touch if you
+know how to fix it using free software.</p>

-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.</p>
-
-<p>Since a few weeks ago, I'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

+ <div class="date">12th February 2015</div>
+ <div class="body"><p>En stund nå har jeg vært nødt til å forholde meg til
+<a href="https://fronter.com/osloskoler/">Fronter</a>, en nettløsning
+Osloskolen bruker for kontakt mellom hjem og skole. Løsningen
+imponerer ikke, og det er lagt opp til at vi foreldre skal logge inn
+regelmessig for å se om noe har endret seg. Idéen om å la folk stikke
+innom nettsider for å se om det har skjedd endringer er så idiotisk at
+jeg har lett etter et alternativ. Fronterløsningen har en innebygget
+løsning der en kan abonnere på forsiden (som viser en oppsummering av
+det en har tilgang til), og få tilsendt en kopi hver natt, men det
+fjerner jo bare behovet for å stikke innom, ikke den idiotiske ideen
+om at folk skal huske hvordan nettsiden så ut sist og oppdage hva som
+er endret.</p>
+
+<p>For å gjøre livet enklere har jeg derfor brukt litt tid på å lage
+et program som kobler seg opp og sjekker etter endringer automatisk,
+slik at jeg kan få beskjed fra datamaskinen når noe endrer seg i
+stedet for å forsøke å finne ut av det selv. I går ble scriptet
+brukbart, og jeg er dermed klar til å dele det med deg.</p>
+
+<p>Jeg startet med å skrive programmet i Python, og hadde en versjon
+som logget inn og hentet ned enkeltsider fra Fronter. Men
+Fronter-websidene suger golfballer gjennom en hageslange, med
+uleselig HTML, flere nivåer av iframes og en struktur på innholdet som
+er svært vanskelig å finne ut av, så jeg ga til slutt opp lxml-parsing
+med Python og forsøkte meg med WWW::Mechanize for Perl som jeg kjente
+fra før. I ettertid har jeg oppdaget at WWW:Mechanize også finnes for
+Python, så jeg kunne antagelig droppet språkbyttet. Men da jeg
+oppdaget det hadde jeg kommet så langt med Perl-utgaven, så jeg hoppet
+ikke tilbake.</p>
+
+<p>For å logge inn i Fronter besøker en enten skolens websider eller
+den sentrale innloggingsiden <tt>https://fronter.com/osloskoler/</tt>.
+Perl-koden for å logge inn ser slik ut:</p>
+
+<pre>
+my $mech = WWW::Mechanize->new();
+$mech->get('https://fronter.com/osloskoler/');
+$mech->submit_form(fields => {
+ username => $username,
+ password => $password,
+} );
+</pre>
+
+<p>Neste steg er å få oversikt over hvilke «rom» en har tilgang til.
+På vår skole er det rom for skolen, biblioteket, elevrådet,
+aktivitetsskolen og klasser der en har unger, og dette vil være
+forskjellig fra person til person. Etter å ha romstert rundt i
+Fronter-grensesnittet endel kom jeg over en grei HTML-side med
+oversikt over rommene,
+<tt>https://fronter.com/osloskoler/adm/projects.phtml?mode=displayRoomchooser</tt>,
+så jeg bruker denne til å hente ut romoversikt med rom-ID.</p>
+
+<pre>
+my %room;
+$mech->get('https://fronter.com/osloskoler/adm/projects.phtml?mode=displayRoomchooser');
+for my $link ($mech->links()) {
+ my $url = $link->url();
+ if ($url =~ m%/links/list_files.phtml\?edit=(\d+)$%) {
+ $room{$link->text()} = $1;
+ }
+}
+</pre>
+
+<p>Når en har rom-ID kan en slå opp websiden for rommet, som starter
+på
+<tt>https://fronter.com/osloskoler/contentframeset.phtml?goto_prjid=$ROMID</tt>
+(der $ROMID byttes ut med rom-ID-tallet). Det gir en side med
+iframes, og en må tre nivåer ned i iframes før en får tak i
+HTML-informasjonen som vises frem når en ser på det aktuelle rommet.
+Her ga jeg opp den robuste parsingen og hardkodet endel URL-er som i
+stedet bør spores opp maskinelt. HTML-informasjonen som vises lagres
+i en fil etter at økt- og innloggings-nøkkel er fjernet og deretter
+bruker jeg <tt>lynx --dump --nolist</tt> for å hente ut en tekstlig
+utgave av websiden. Denne tekstlige utgaven sammenlignes med forrige
+versjon og oversikt over endringer kan så sendes ut på egnet vis.</p>
+
+<p>Jeg valgte å bruke git til å holde rede på endringer, så jeg
+sjekker inn HTML og tekst-utgaver i git og bruker git til å vise frem
+endringene i tekstutgavene. Programvaren for å gjøre dette er testet
+på Debian GNU/Linux og kan
+<a href="https://github.com/petterreinholdtsen/fronter-scraper-oslo">lastes
+ned fra github</a>.</p>
+
+<p>For å bruke dette selv, kjør følgende kommandoer på din
+Debian-maskin (forutsetter sudo-tilgang for installasjon av
+programvare):</p>
+
+<pre>
+sudo apt-get install git lynx-cur libio-prompter-perl libwww-mechanize-perl \
+ libconfig-inifiles-perl
+git clone https://github.com/petterreinholdtsen/fronter-scraper-oslo
+cd fronter-scraper-oslo
+./update-git
+</pre>
+
+<p>Det gjenstår endel, men systemet er allerede nyttig for meg. Jeg
+ønsker at systemet også skal laste ned PDF-er og slikt som er lagt ut
+for nedlasting på sidene, slik at f.eks. ukeplaner kommer inn i
+git-arkivet mitt automatisk og jeg får automatisk beskjed når ny
+ukeplan er lagt ut. Kanskje du kan bidra med å få det på plass, eller
+kanskje du har andre ting du vil fikse? Jeg tar gjerne imot endringer
+og forbedringer. Det er mye som kan gjøres bedre, og scriptet er ikke
+veldig robust mot endringer hos nettsidene til Fronter. Jeg regner
+dermed med at det vil trengs oppdateringer jevnlig etter hvert som
+Fronter-løsningen endrer seg.</p>

<div class="entry">
- <div class="title"><a href="http://people.skolelinux.org/pere/blog/Install_hardware_dependent_packages_using_tasksel__Isenkram_0_7_.html">Install hardware dependent packages using tasksel (Isenkram 0.7)</a></div>
- <div class="date">23rd April 2014</div>
- <div class="body"><p>It would be nice if it was easier in Debian to get all the hardware
-related packages relevant for the computer installed automatically.
-So I implemented one, using
-<a href="http://packages.qa.debian.org/isenkram">my Isenkram
-package</a>. To use it, install the tasksel and isenkram packages and
-run tasksel as user root. You should be presented with a new option,
-"Hardware specific packages (autodetected by isenkram)". When you
-select it, tasksel will install the packages isenkram claim is fit for
-the current hardware, hot pluggable or not.<p>
-
-<p>The implementation is in two files, one is the tasksel menu entry
-description, and the other is the script used to extract the list of
-packages to install. The first part is in
-<tt>/usr/share/tasksel/descs/isenkram.desc</tt> and look like
-this:</p>
-
-<p><blockquote><pre>
-Task: isenkram
-Section: hardware
-Description: Hardware specific packages (autodetected by isenkram)
- Based on the detected hardware various hardware specific packages are
- proposed.
-Test-new-install: mark show
-Relevance: 8
-Packages: for-current-hardware
-</pre></blockquote></p>
-
-<p>The second part is in
-<tt>/usr/lib/tasksel/packages/for-current-hardware</tt> and look like
-this:</p>
-
-<p><blockquote><pre>
-#!/bin/sh
-#
-(
- isenkram-lookup
- isenkram-autoinstall-firmware -l
-) | sort -u
-</pre></blockquote></p>
-
-<p>All in all, a very short and simple implementation making it
-trivial to install the hardware dependent package we all may want to
-have installed on our machines. I've not been able to find a way to
-get tasksel to tell you exactly which packages it plan to install
-before doing the installation. So if you are curious or careful,
-check the output from the isenkram-* command line tools first.</p>
-
-<p>The information about which packages are handling which hardware is
-fetched either from the isenkram package itself in
-/usr/share/isenkram/, from git.debian.org or from the APT package
-database (using the Modaliases header). The APT package database
-parsing have caused a nasty resource leak in the isenkram daemon (bugs
-<a href="http://bugs.debian.org/719837">#719837</a> and
-<a href="http://bugs.debian.org/730704">#730704</a>). The cause is in
-the python-apt code (bug
-<a href="http://bugs.debian.org/745487">#745487</a>), but using a
-workaround I was able to get rid of the file descriptor leak and
-reduce the memory leak from ~30 MiB per hardware detection down to
-around 2 MiB per hardware detection. It should make the desktop
-daemon a lot more useful. The fix is in version 0.7 uploaded to
-unstable today.</p>
-
-<p>I believe the current way of mapping hardware to packages in
-Isenkram is is a good draft, but in the future I expect isenkram to
-use the AppStream data source for this. A proposal for getting proper
-AppStream support into Debian is floating around as
-<a href="https://wiki.debian.org/DEP-11">DEP-11</a>, and
-<a href="https://wiki.debian.org/SummerOfCode2014/Projects#SummerOfCode2014.2FProjects.2FAppStreamDEP11Implementation.AppStream.2FDEP-11_for_the_Debian_Archive">GSoC
-project</a> will take place this summer to improve the situation. I
-look forward to seeing the result, and welcome patches for isenkram to
-start using the information when it is ready.</p>
-
-<p>If you want your package to map to some specific hardware, either
-add a "Xb-Modaliases" header to your control file like I did in
-<a href="http://packages.qa.debian.org/pymissile">the pymissile
-package</a> or submit a bug report with the details to the isenkram
-package. See also
-<a href="http://people.skolelinux.org/pere/blog/tags/isenkram/">all my
-blog posts tagged isenkram</a> for details on the notation. I expect
-the information will be migrated to AppStream eventually, but for the
-moment I got no better place to store it.</p>

+ <div class="date">10th February 2015</div>
+ <div class="body"><p>Aftenposten, one of the largest newspapers in Norway, today report
+that
+<a href="http://www.aftenposten.no/reise/Slik-skannes-kroppen-din-i-fremtidens-sikkerhetskontroll-490666_1.snd">three
+of the nude body scanners now is put to use at Gardermoen</a>, the
+main airport in Norway. This way the travelers can have their body
+photographed without cloths when visiting Norway. Of course this
+horrible news is presented with a positive spin, stating that "now
+travelers can move past the security check point faster and more
+efficiently", but fail to mention that the machines in question take
+pictures of their nude bodies and store them internally in the
+computer, while only presenting sketch figure of the body to the
+public. The article is written in a way that leave the impression
+that the new machines do not take these nude pictures and only create
+the sketch figures. In reality the same nude pictures are still
+taken, but not presented to everyone. They are still available for
+the owners of the system and the people doing maintenance of the
+scanners, as long as they are taken and stored.</p>
+
+<p>Wikipedia have a more on
+<a href="https://en.wikipedia.org/wiki/Full_body_scanner">Full body
+scanners</a>, including example images and a summary of the
+controversy about these scanners.</p>
+
+<p>Personally I will decline to use these machines, as I believe strip
+searches of my body is a very intrusive attack on my privacy, and not
+something everyone should have to accept to travel.</p>
