- <div class="body"><p>I spent last weekend at <a href="http://www.makercon.no/">Makercon
-Nordic</a>, a great conference and workshop for makers in Norway and
-the surrounding countries. I had volunteered on behalf of the
-Norwegian Unix Users Group (NUUG) to video record the talks, and we
-had a great and exhausting time recording the entire day, two days in
-a row. There were only two of us, Hans-Petter and me, and we used the
-regular video equipment for NUUG, with a
-<a href="http://dvswitch.alioth.debian.org/wiki/">dvswitch</a>, a
-camera and a VGA to DV convert box, and mixed video and slides
-live.</p>
-
-<p>Hans-Petter did the post-processing, consisting of uploading the
-around 180 GiB of raw video to Youtube, and the result is
-<a href="https://www.youtube.com/user/MakerConNordic/">now becoming
-public</a> on the MakerConNordic account. The videos have the license

+ <div class="date">12th May 2015</div>
+ <div class="body"><p>Noen finner det vanskelig å tro at Stortinget faktisk har vedtatt å
+kreve at alle norske borgerne må avgi fingeravtrykk til politiet for å
+fungere i samfunnet. Jeg er blitt spurt hva som er grunnlaget for
+<a href="http://people.skolelinux.org/pere/blog/Norwegian_citizens_now_required_by_law_to_give_their_fingerprint_to_the_police.html">min
+påstand i forrige bloggpost</a> om at det nå blir krav om å avgi
+fingeravtrykk til politiet for å fungere som borger i Norge. De som
+spør klarer ikke lese det ut fra det som er vedtatt. Her er en liten
+oppsummering om hva jeg baserer det på. Det sies ikke direkte i
+hverken proposisjon, innstilling eller vedtak, men fremgår når en ser
+på indirekte formuleringer.</p>
+
+<p>I
+<a href="https://www.regjeringen.no/nb/dokumenter/prop.-66-l-2014-2015/id2399703/">stortingsproposisjon
+66</a>, avsnitt 6.3.5 (Avgivelse av biometriske personopplysninger)
+står det<p>
+
+<p><blockquote>
+
+ <p>Departementet foreslår at både ansiktsfoto og fingeravtrykk skal
+ kunne opptas og lagres som identifikasjonsdata i de nasjonale
+ ID-kortene, på samme måte som i passene. Lovforslaget er derfor
+ utformet i tråd med passloven § 6 annet ledd, som fastslår at det
+ til bruk for senere verifisering eller kontroll av passinnehaverens
+ identitet kan innhentes og lagres i passet biometrisk
+ personinformasjon i form av ansiktsfoto og fingeravtrykk (to
+ fingre). Dagens ordning med lagring av ansiktsfoto og fingeravtrykk
+ i et kontaktløst smartkort i passet er basert på internasjonale
+ standarder. Fingeravtrykkene i nasjonalt ID-kort vil bli beskyttet
+ på samme måte som fingeravtrykkene i passene.</p>
+
+ <p>[...]</p>
+
+ <p>For norske forhold understreker departementet at innføring av
+ nasjonale ID-kort sammen med innføring av nye systemer for sikrere
+ utstedelse og kontroll av pass og relaterte dokumenter gir mulighet
+ til å utforme ordningen slik at den best mulig møter utfordringene
+ forbundet med identitetskriminalitet. Det tilsier at fingeravtrykk
+ opptas og lagres i alle nasjonale ID-kort.</p>
+</blockquote></p>
+
+<p>Departementet sier altså at sin anbefaling er at fingeravtrykk skal
+opptas og lagres i alle nasjonale ID-kort. Det skrives som om det
+blir valgfritt, på samme måten som det skrives passloven, der det i
+loven sier at det kan
+«<a href="https://lovdata.no/dokument/NL/lov/1997-06-19-82#§6">innhentes
+og lagres i passet biometrisk personinformasjon i form av ansiktsfoto
+og fingeravtrykk (to fingre)</a>». Men på tross av bruken av «kan» i
+passloven er det innført krav om å avgi fingeravtrykk for å få et pass
+i Norge. Proposisjonen sier i tillegg i del 1 (Proposisjonens
+hovedinnhold) at ID-kortene skal være like pålitelig som pass og ha
+samme sikkerhetsnivå som pass. Departementet foreslår altså at
+ID-kortene skal gis etter samme regler som for pass.</p>
+
+<p>Formuleringene fra hovedinnholdet i proposisjonen er videreført i
+<a href="https://www.stortinget.no/no/Saker-og-publikasjoner/Publikasjoner/Innstillinger/Stortinget/2014-2015/inns-201415-243/?lvl=0">innstillingen
+fra stortingskomiteen</a>, der det konkret står «De foreslåtte reglene
+vil gi befolkningen tilbud om et offentlig utstedt identitetsbevis som
+vil være like pålitelig som passet, og mer praktisk å bruke som
+legitimasjon» og «Det nasjonale ID-kortet skal også holde samme
+sikkerhetsnivå som passet». Komiteen har altså ingen kommentarer
+eller innsigelser til dette forslaget, og gjorde i debatten da saken
+ble vedtatt det klart at dette var en god sak og at en enstemmig
+komité var glad for resultatet. Stortinget har dermed stilt seg helt
+og fullt bak departementets forslag.</p>
+
+<p>For meg er det åpenbart når en leser proposisjonen at «like
+pålitelig» og «samme sikkerhetsnivå» vil bli tolket av departementet
+som «med samme biometrisk informasjon som i passene», og departementet
+forklarer i tillegg i proposisjonen at de har tenkt at
+fingeravtrykkene «vil bli beskyttet på samme måte som fingeravtrykkene
+i passene». Jeg ser det dermed som åpenbart at den samme
+tvangsinnhentingen av fingeravtrykk som gjelder for pass vil bli
+viderført til de nasjonale ID-kortene.</p>
+
+<p>Det eneste som kan endre dette er massive protester fra
+befolkningen på at folk som ikke er mistenkt for noe kriminelt skal
+tvinges til å gi fingeravtrykket til politiet for å f.eks. kunne få
+bankkonto eller stemme ved valg. Det kunne få departementet til å
+snu. Det tror jeg ikke vil skje.</p>

- <div class="date">22nd October 2014</div>
- <div class="body"><p>If you ever had to moderate a mailman list, like the ones on
-alioth.debian.org, you know the web interface is fairly slow to
-operate. First you visit one web page, enter the moderation password
-and get a new page shown with a list of all the messages to moderate
-and various options for each email address. This take a while for
-every list you moderate, and you need to do it regularly to do a good
-job as a list moderator. But there is a quick alternative,
-<a href="http://heim.ifi.uio.no/kjetilho/hacks/#listadmin">the
-listadmin program</a>. It allow you to check lists for new messages
-to moderate in a fraction of a second. Here is a test run on two
-lists I recently took over:</p>
-
-<p><blockquote><pre>
-% time listadmin xiph
-fetching data for pkg-xiph-commits@lists.alioth.debian.org ... nothing in queue
-fetching data for pkg-xiph-maint@lists.alioth.debian.org ... nothing in queue
-
-real 0m1.709s
-user 0m0.232s
-sys 0m0.012s
-%
-</pre></blockquote></p>
-
-<p>In 1.7 seconds I had checked two mailing lists and confirmed that
-there are no message in the moderation queue. Every morning I
-currently moderate 68 mailman lists, and it normally take around two
-minutes. When I took over the two pkg-xiph lists above a few days
-ago, there were 400 emails waiting in the moderator queue. It took me
-less than 15 minutes to process them all using the listadmin
-program.</p>
-
-<p>If you install
-<a href="https://tracker.debian.org/pkg/listadmin">the listadmin
-package</a> from Debian and create a file <tt>~/.listadmin.ini</tt>
-with content like this, the moderation task is a breeze:</p>
-
-<p><blockquote><pre>
-username@example.org
-spamlevel 23
-default discard
-discard_if_reason "Posting restricted to members only. Remove us from your mail list."
-
-password secret
-adminurl https://{domain}/mailman/admindb/{list}
-mailman-list@lists.example.com
-
-password hidden
-other-list@otherserver.example.org
-</pre></blockquote></p>
-
-<p>There are other options to set as well. Check the manual page to
-learn the details.</p>
-
-<p>If you are forced to moderate lists on a mailman installation where
-the SSL certificate is self signed or not properly signed by a
-generally accepted signing authority, you can set a environment
-variable when calling listadmin to disable SSL verification:</p>
-
-<p><blockquote><pre>
-PERL_LWP_SSL_VERIFY_HOSTNAME=0 listadmin
-</pre></blockquote></p>
-
-<p>If you want to moderate a subset of the lists you take care of, you
-can provide an argument to the listadmin script like I do in the
-initial screen dump (the xiph argument). Using an argument, only
-lists matching the argument string will be processed. This make it
-quick to accept messages if you notice the moderation request in your
-email.</p>
-
-<p>Without the listadmin program, I would never be the moderator of 68
-mailing lists, as I simply do not have time to spend on that if the
-process was any slower. The listadmin program have saved me hours of
-time I could spend elsewhere over the years. It truly is nice free
-software.</p>

+ <div class="date">10th May 2015</div>
+ <div class="body"><p>5 days ago, the Norwegian Parliament decided, unanimously, that all
+citizens of Norway, no matter if they are suspected of something
+criminal or not, are
+<a href="https://www.holderdeord.no/votes/1430838871e">required to
+give fingerprints to the police</a> (vote details from Holder de
+ord). The law make it sound like it will be optional, but in a few
+years there will be no option any more. The ID will be required to
+vote, to get a bank account, a bank card, to change address on the
+post office, to receive an electronic ID or to get a drivers license
+and many other tasks required to function in Norway. The banks plan
+to stop providing their own ID on the bank cards when this new
+national ID is introduced, and the national road authorities plan to
+change the drivers license to no longer be usable as identity cards.
+In effect, to function as a citizen in Norway a national ID card will
+be required, and to get it one need to provide the fingerprints to
+the police.</p>
+
+<p>In addition to handing the fingerprint to the police (which
+promised to not make a copy of the fingerprint image at that point in
+time, but say nothing about doing it later), a picture of the
+fingerprint will be stored on the RFID chip, along with a picture of
+the face and other information about the person. Some of the
+information will be encrypted, but the encryption will be the same
+system as currently used in the passports. The codes to decrypt will
+be available to a lot of government offices and their suppliers around
+the globe, but for those that do now know anyone in those circles it
+is good to know that
+
+<a href="http://www.theguardian.com/technology/2006/nov/17/news.homeaffairs">the
+encryption is already broken</a>. And they
+<a href="http://www.networkworld.com/article/2215057/wireless/bad-guys-could-read-rfid-passports-at-217-feet--maybe-a-lot-more.html">can
+be read from 70 meters away</a>. This can be mitigated a bit by
+keeping it in a Faraday cage (metal box or metal wire container), but
+one will be required to take it out of there often enough to expose
+ones private and personal information to a lot of people that have no
+business getting access to that information.</p>
+
+<p>The new Norwegian national IDs are a vehicle for identity theft,
+and I feel sorry for us all having politicians accepting such invasion
+of privacy without any objections. So are the Norwegian passports,
+but it has been possible to function in Norway without those so far.
+That option is going away with the passing of the new law. In this, I
+envy the Germans, because for them it is optional how much biometric
+information is stored in their national ID.</p>
+
+<p>And if forced collection of fingerprints was not bad enough, the
+information collected in the national ID card register can be handed
+over to foreign intelligence services and police authorities, "when
+extradition is not considered disproportionate".</p>

- <div class="title"><a href="http://people.skolelinux.org/pere/blog/Debian_Jessie__PXE_and_automatic_firmware_installation.html">Debian Jessie, PXE and automatic firmware installation</a></div>
- <div class="date">17th October 2014</div>
- <div class="body"><p>When PXE installing laptops with Debian, I often run into the
-problem that the WiFi card require some firmware to work properly.
-And it has been a pain to fix this using preseeding in Debian.
-Normally something more is needed. But thanks to
-<a href="https://packages.qa.debian.org/i/isenkram.html">my isenkram
-package</a> and its recent tasksel extension, it has now become easy
-to do this using simple preseeding.</p>
-
-<p>The isenkram-cli package provide tasksel tasks which will install
-firmware for the hardware found in the machine (actually, requested by
-the kernel modules for the hardware). (It can also install user space
-programs supporting the hardware detected, but that is not the focus
-of this story.)</p>
-
-<p>To get this working in the default installation, two preeseding
-values are needed. First, the isenkram-cli package must be installed
-into the target chroot (aka the hard drive) before tasksel is executed
-in the pkgsel step of the debian-installer system. This is done by
-preseeding the base-installer/includes debconf value to include the
-isenkram-cli package. The package name is next passed to debootstrap
-for installation. With the isenkram-cli package in place, tasksel
-will automatically use the isenkram tasks to detect hardware specific
-packages for the machine being installed and install them, because
-isenkram-cli contain tasksel tasks.</p>
-
-<p>Second, one need to enable the non-free APT repository, because
-most firmware unfortunately is non-free. This is done by preseeding
-the apt-mirror-setup step. This is unfortunate, but for a lot of
-hardware it is the only option in Debian.</p>
-
-<p>The end result is two lines needed in your preseeding file to get
-firmware installed automatically by the installer:</p>
-
-<p><blockquote><pre>
-base-installer base-installer/includes string isenkram-cli
-apt-mirror-setup apt-setup/non-free boolean true
-</pre></blockquote></p>
-
-<p>The current version of isenkram-cli in testing/jessie will install
-both firmware and user space packages when using this method. It also
-do not work well, so use version 0.15 or later. Installing both
-firmware and user space packages might give you a bit more than you
-want, so I decided to split the tasksel task in two, one for firmware
-and one for user space programs. The firmware task is enabled by
-default, while the one for user space programs is not. This split is
-implemented in the package currently in unstable.</p>
-
-<p>If you decide to give this a go, please let me know (via email) how
-this recipe work for you. :)</p>
-
-<p>So, I bet you are wondering, how can this work. First and
-foremost, it work because tasksel is modular, and driven by whatever
-files it find in /usr/lib/tasksel/ and /usr/share/tasksel/. So the
-isenkram-cli package place two files for tasksel to find. First there
-is the task description file (/usr/share/tasksel/descs/isenkram.desc):</p>
-
-<p><blockquote><pre>
-Task: isenkram-packages
-Section: hardware
-Description: Hardware specific packages (autodetected by isenkram)
- Based on the detected hardware various hardware specific packages are
- proposed.
-Test-new-install: show show
-Relevance: 8
-Packages: for-current-hardware
-
-Task: isenkram-firmware
-Section: hardware
-Description: Hardware specific firmware packages (autodetected by isenkram)
- Based on the detected hardware various hardware specific firmware
- packages are proposed.
-Test-new-install: mark show
-Relevance: 8
-Packages: for-current-hardware-firmware
-</pre></blockquote></p>
-
-<p>The key parts are Test-new-install which indicate how the task
-should be handled and the Packages line referencing to a script in
-/usr/lib/tasksel/packages/. The scripts use other scripts to get a
-list of packages to install. The for-current-hardware-firmware script
-look like this to list relevant firmware for the machine:
-
-<p><blockquote><pre>
-#!/bin/sh
-#
-PATH=/usr/sbin:$PATH
-export PATH
-isenkram-autoinstall-firmware -l
-</pre></blockquote></p>
-
-<p>With those two pieces in place, the firmware is installed by
-tasksel during the normal d-i run. :)</p>
-
-<p>If you want to test what tasksel will install when isenkram-cli is
-installed, run <tt>DEBIAN_PRIORITY=critical tasksel --test
---new-install</tt> to get the list of packages that tasksel would
-install.</p>
-
-<p><a href="https://wiki.debian.org/DebianEdu/">Debian Edu</a> will be
-pilots in testing this feature, as isenkram is used there now to
-install firmware, replacing the earlier scripts.</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>

+ for the hardware present.
+
+=== Fixed bugs ===
+
+A number of bugs have been fixed in this release; the most noticeable
+from a user perspective:
+
+ * Inserting incorrect DNS information in Gosa will no longer break
+ DNS completely, but instead stop DNS updates until the incorrect
+ information is corrected (710362)
+
+ * shutdown-at-night now shuts the system down if gdm3 is used (775608).
+
+=== Sugar desktop removed ===
+
+As the Sugar desktop was removed from Debian Jessie, it is also not
+available in Debian Edu jessie.
+
+
+== 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="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 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>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>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>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>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>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>

- <div class="date">26th September 2014</div>
- <div class="body"><p>The <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux
-project</a> provide a Linux solution for schools, including a
-powerful desktop with education software, a central server providing
-web pages, user database, user home directories, central login and PXE
-boot of both clients without disk and the installation to install Debian
-Edu on machines with disk (and a few other services perhaps to small
-to mention here). We in the Debian Edu team are currently working on
-the Jessie based version, trying to get everything in shape before the
-freeze, to avoid having to maintain our own package repository in the
-future. The
-<a href="https://wiki.debian.org/DebianEdu/Status/Jessie">current
-status</a> can be seen on the Debian wiki, and there is still heaps of
-work left. Some fatal problems block testing, breaking the installer,
-but it is possible to work around these to get anyway. Here is a
-recipe on how to get the installation limping along.</p>
-
-<p>First, download the test ISO via
-<a href="ftp://ftp.skolelinux.no/cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-1.iso">ftp</a>,
-<a href="http://ftp.skolelinux.no/cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-1.iso">http</a>
-or rsync (use
-ftp.skolelinux.org::cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-1.iso).
-The ISO build was broken on Tuesday, so we do not get a new ISO every
-12 hours or so, but thankfully the ISO we already got we are able to
-install with some tweaking.</p>
-
-<p>When you get to the Debian Edu profile question, go to tty2
-(use Alt-Ctrl-F2), run</p>
-
-<p><blockquote><pre>
-nano /usr/bin/edu-eatmydata-install
-</pre></blockquote></p>
-
-<p>and add 'exit 0' as the second line, disabling the eatmydata
-optimization. Return to the installation, select the profile you want
-and continue. Without this change, exim4-config will fail to install
-due to a known bug in eatmydata.</p>
-
-<p>When you get the grub question at the end, answer /dev/sda (or if
-this do not work, figure out what your correct value would be. All my
-test machines need /dev/sda, so I have no advice if it do not fit
-your need.</p>
-
-<p>If you installed a profile including a graphical desktop, log in as
-root after the initial boot from hard drive, and install the
-education-desktop-XXX metapackage. XXX can be kde, gnome, lxde, xfce
-or mate. If you want several desktop options, install more than one
-metapackage. Once this is done, reboot and you should have a working
-graphical login screen. This workaround should no longer be needed
-once the education-tasks package version 1.801 enter testing in two
-days.</p>
-
-<p>I believe the ISO build will start working on two days when the new
-tasksel package enter testing and Steve McIntyre get a chance to
-update the debian-cd git repository. The eatmydata, grub and desktop
-issues are already fixed in unstable and testing, and should show up
-on the ISO as soon as the ISO build start working again. Well the
-eatmydata optimization is really just disabled. The proper fix
-require an upload by the eatmydata maintainer applying the patch
-provided in bug <a href="https://bugs.debian.org/702711">#702711</a>.
-The rest have proper fixes in unstable.</p>
-
-<p>I hope this get you going with the installation testing, as we are
-quickly running out of time trying to get our Jessie based
-installation ready before the distribution freeze in a month.</p>

- <div class="date">21st September 2014</div>
- <div class="body"><p>Rundt omkring i Oslo og Østlandsområdet henger det bokser over
-veiene som jeg har lurt på hva gjør. De har ut fra plassering og
-vinkling sett ut som bokser som sniffer ut et eller annet fra
-forbipasserende trafikk, men det har vært uklart for meg hva det er de
-leser av. Her om dagen tok jeg bilde av en slik boks som henger under
-<a href="http://www.openstreetmap.no/?zoom=19&mlat=59.96396&mlon=10.34443&layers=B00000">ei
-skibru på Sollihøgda</a>:</p>
-
-<p align="center"><img width="60%" src="http://people.skolelinux.org/pere/blog/images/2014-09-13-kapsch-sollihogda-crop.jpeg"></p>
-
-<p>Boksen er tydelig merket «Kapsch >>>», logoen til
-<a href="http://www.kapsch.net/">det sveitsiske selskapet Kapsch</a> som
-blant annet lager sensorsystemer for veitrafikk. Men de lager mye
-forskjellig, og jeg kjente ikke igjen boksen på utseendet etter en
-kjapp titt på produktlista til selskapet.</p>
-
-<p>I og med at boksen henger over veien E16, en riksvei vedlikeholdt
-av Statens Vegvesen, så antok jeg at det burde være mulig å bruke
-REST-API-et som gir tilgang til vegvesenets database over veier,
-skilter og annet veirelatert til å finne ut hva i alle dager dette
-kunne være. De har både
-<a href="https://www.vegvesen.no/nvdb/api/dokumentasjon/datakatalog">en
-datakatalog</a> og
-<a href="https://www.vegvesen.no/nvdb/api/dokumentasjon/sok">et
-søk</a>, der en kan søke etter ulike typer oppføringer innen for et
-gitt geografisk område. Jeg laget et enkelt shell-script for å hente
-ut antall av en gitt type innenfor området skibrua dekker, og listet
-opp navnet på typene som ble funnet. Orket ikke slå opp hvordan
-URL-koding av aktuelle strenger kunne gjøres mer generisk, og brukte
-en stygg sed-linje i stedet.</p>

-
-<p>Av disse ser ID 775 og 862 mest relevant ut. ID 775 antar jeg
-refererer til fotoboksen som står like ved brua, mens
-«Reisetidsregistreringspunkt» kanskje kan være boksen som henger der.
-Hvordan finner jeg så ut hva dette kan være for noe. En titt på
-<a href="http://labs.vegdata.no/nvdb-datakatalog/862-Reisetidsregistreringspunkt/">datakatalogsiden
-for ID 862/Reisetidsregistreringspunkt</a> viser at det er finnes 53
-slike målere i Norge, og hvor de er plassert, men gir ellers få
-detaljer. Det er plassert 40 på østlandet og 13 i Trondheimsregionen.
-Men siden nevner «AutoPASS», og hvis en slår opp oppføringen på
-Sollihøgda nevner den «Ciber AS» som ID for eksternt system. (Kan det
-være snakk om
-<a href="http://www.proff.no/selskap/ciber-norge-as/oslo/internettdesign-og-programmering/Z0I3KMF4/">Ciber
-Norge AS</a>, et selskap eid av Ciber Europe Bv?) Et nettsøk på
- «Ciber AS autopass» fører meg til en artikkel fra NRK Trøndelag i
- 2013 med tittel
-«<a href="http://www.nrk.no/trondelag/sjekk-dette-hvis-du-vil-unnga-ko-1.11327947">Sjekk
-dette hvis du vil unngå kø</a>». Artikkelen henviser til vegvesenets
-nettside
-<a href="http://www.reisetider.no/reisetid/forside.html">reisetider.no</a>
-som har en
-<a href="http://www.reisetider.no/reisetid/omrade.html?omrade=5">kartside
-for Østlandet</a> som viser at det måles mellom Sandvika og Sollihøgda.
-Det kan dermed se ut til at jeg har funnet ut hva boksene gjør.</p>
-
-<p>Hvis det stemmer, så er dette bokser som leser av AutoPASS-ID-en
-til alle passerende biler med AutoPASS-brikke, og dermed gjør det mulig
-for de som kontrollerer boksene å holde rede på hvor en gitt bil er
-når den passerte et slikt målepunkt. NRK-artikkelen forteller at
-denne informasjonen i dag kun brukes til å koble to
-AutoPASS-brikkepasseringer passeringer sammen for å beregne
-reisetiden, og at bruken er godkjent av Datatilsynet. Det er desverre
-ikke mulig for en sjåfør som passerer under en slik boks å kontrollere
-at AutoPASS-ID-en kun brukes til dette i dag og i fremtiden.</p>
-
-<p>I tillegg til denne type AutoPASS-sniffere vet jeg at det også
-finnes mange automatiske stasjoner som tar betalt pr. passering (aka
-bomstasjoner), og der lagres informasjon om tid, sted og bilnummer i
-10 år. Finnes det andre slike sniffere plassert ut på veiene?</p>
-
-<p>Personlig har jeg valgt å ikke bruke AutoPASS-brikke, for å gjøre
-det vanskeligere og mer kostbart for de som vil invadere privatsfæren
-og holde rede på hvor bilen min beveger seg til enhver tid. Jeg håper
-flere vil gjøre det samme, selv om det gir litt høyere private
-utgifter (dyrere bompassering). Vern om privatsfæren koster i disse
-dager.</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>

- <div class="date">16th September 2014</div>
- <div class="body"><p>The <a href="https://www.debian.org/">Debian</a> installer could be
-a lot quicker. When we install more than 2000 packages in
-<a href="http://www.skolelinux.org/">Skolelinux / Debian Edu</a> using
-tasksel in the installer, unpacking the binary packages take forever.
-A part of the slow I/O issue was discussed in
-<a href="https://bugs.debian.org/613428">bug #613428</a> 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.</p>
-
-<p>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
-<a href="https://packages.qa.debian.org/eatmydata">eatmydata</a>, 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
-"eatmydata $program $@", to get the same effect.
-Two days ago I decided to test the idea, and wrapped up a simple
-implementation for the Debian Edu udeb.</p>
-
-<p>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 "pkgsel: starting tasksel" and the
-"pkgsel: finishing up" 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.</p>

-</table></p>
-
-<p>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.</p>
-
-<p>The speedup is implemented by using two hooks in
-<a href="https://www.debian.org/devel/debian-installer/">Debian
-Installer</a>, 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.</p>
-
-<p>I've implemented this in the
-<a href="https://packages.qa.debian.org/debian-edu-install">debian-edu-install</a>
-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:</p>
-
-<p><blockquote><pre>
-#!/bin/sh
-set -e
-. /usr/share/debconf/confmodule
-info() {
- logger -t my-pkgsel "info: $*"
-}
-error() {
- logger -t my-pkgsel "error: $*"
-}
-override_install() {
- apt-install eatmydata || true
- if [ -x /target/usr/bin/eatmydata ] ; then
- for bin in dpkg apt-get aptitude tasksel ; do
- file=/usr/bin/$bin
- # Test that the file exist and have not been diverted already.
- if [ -f /target$file ] ; then
- info "diverting $file using eatmydata"
- printf "#!/bin/sh\neatmydata $bin.distrib \"\$@\"\n" \
- > /target$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 "unable to divert $file, as it is missing."
- fi
- done
- else
- error "unable to find /usr/bin/eatmydata after installing the eatmydata pacage"
- fi
-}
-
-override_install
-</pre></blockquote></p>
-
-<p>To clean up, another shell script should go into
-/usr/lib/finish-install.d/ with code like this:
-
-<p><blockquote><pre>
-#! /bin/sh -e
-. /usr/share/debconf/confmodule
-error() {
- logger -t my-finish-install "error: $@"
-}
-remove_install_override() {
- for bin in dpkg apt-get aptitude tasksel ; do
- file=/usr/bin/$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 "Missing divert for $file."
- fi
- done
- sync # Flush file buffers before continuing
-}
-
-remove_install_override
-</pre></blockquote></p>
-
-<p>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.</p>
-
-<p>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'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.</p>
-
-<p>Update 2014-09-24: Since a few days ago, enabling this optimization
-will break installation of all programs using gnutls because of
-<a href="https://bugs.debian.org/702711">bug #702711</a>. An updated
-eatmydata package in Debian will solve it.</p>
-
-<p>Update 2014-10-17: The bug mentioned above is fixed in testing and
-the optimization work again. And I have discovered that the
-dpkg-divert trick is not really needed and implemented a slightly
-simpler approach as part of the debian-edu-install package. See
-tools/edu-eatmydata-install in the source package.</p>

+<a href="https://en.wikipedia.org/wiki/Laura_Poitras">Laura Poitras</a>
+finally will show up in Norway. According to the magazine
+<a href="http://montages.no/">Montages</a>, a deal has finally been
+made for
+<a href="http://montages.no/nyheter/snowden-dokumentaren-citizenfour-far-norsk-kinodistribusjon/">Cinema
+distribution in Norway</a> and the movie will have its premiere soon.
+This is great news. As part of my involvement with
+<a href="http://www.nuug.no/">the Norwegian Unix User Group</a>, me and
+a friend have
+<a href="http://www.nuug.no/news/Dokumentar_om_Snowdenbekreftelsene_til_Norge_.shtml">tried
+to get the movie to Norway</a> ourselves, but obviously
+<a href="http://www.nuug.no/news/Dokumentar_om_Snowdenbekreftelsene_endelig_til_Norge_.shtml">we
+were too late</a> and Tor Fosse beat us to it. I am happy he did, as
+the movie will make its way to the public and we do not have to make
+it happen ourselves.
+<a href="https://www.youtube.com/watch?v=XiGwAvd5mvM">The trailer</a>
+can be seen on youtube, if you are curious what kind of film this
+is.</p>
+
+<p>The whistle blower Edward Snowden really deserve political asylum
+here in Norway, but I am afraid he would not be safe.</p>

- <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="title"><a href="http://people.skolelinux.org/pere/blog/The_Norwegian_open_channel_Frikanalen___24x7_on_the_Internet.html">The Norwegian open channel Frikanalen - 24x7 on the Internet</a></div>
+ <div class="date">25th February 2015</div>
+ <div class="body"><p>The Norwegian nationwide open channel
+<a href="http://www.frikanalen.no/">Frikanalen</a> is still going
+strong. It allow everyone to send the video they want on national
+television. It is a TV station administrated completely using a web
+browser, running only <ahref="https://github.com/Frikanalen">Free
+Software</a>, providing <ahref="http://beta.frikanalen.tv/api">a REST
+api</a> for administrators and members, and with distribution on the
+national DVB-T distribution network RiksTV. But only between 12:00
+and 17:30 Norwegian time. This has finally changed, after many years
+with limited distribution. A few weeks ago, we set up a Ogg Theora
+stream via icecast to allow everyone with Internet access to check out
+the channel the rest of the day. This is presented on
+<a href="http://www.frikanalen.tv/se">the Frikanalen web site now</a>. And
+since a few days ago, the channel is also available
+via <a href="https://www.uninett.no/iptv-tilgang">multicast on
+UNINETT</a>, available for those using IPTV TVs and set-top boxes in
+the Norwegian National Research and Education network.</p>
+
+<p>If you want to see what is on the channel, point your media player
+to one of these sources. The first should work with most players and
+browsers, while as far as I know, the multicast UDP stream only work
+with VLC.</p>
+
+<ul>
+ <li><a href="http://video.nuug.no/frikanalen.ogv">http://video.nuug.no/frikanalen.ogv</a></li>
+ <li>udp://@224.17.43.129:1234</li>
+</ul>
+
+<p>The Ogg Theora / icecast stream is not working well, as the video
+and audio is slightly out of sync. We have not been able to figure
+out how to fix it. It is generated by recoding a internal MPEG
+transport stream with MPEG4 coded video (ie H.264) to Ogg Theora /
+Vorbis, and the result is less then stellar. If you have ideas how to
+fix it, please let us know on frikanalen (at) nuug.no. We currently
+use this with ffmpeg2theora 0.29:</p>
+
+<blockquote><pre>
+./ffmpeg2theora.linux <OBE_gemini_URL.ts> -F 25 -x 720 -y 405 \
+ --deinterlace --inputfps 25 -c 1 -H 48000 --keyint 8 --buf-delay 100 \
+ --nosync -V 700 -o - | oggfwd video.nuug.no 8000 <pw> /frikanalen.ogv
+</pre></blockquote>
+
+<p>If you get the multicast UDP stream working, please let me know, as
+I am curious how far the multicast stream reach. It do not make it to
+my home network, nor any other commercially available network in
+Norway that I am aware of.</p>
