- <description><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 finger
-print 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>

+ <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/UsingQR____Electronic__paper_invoices_using_JSON_and_QR_codes.html</guid>
+ <pubDate>Sat, 19 Mar 2016 09:40:00 +0100</pubDate>
+ <description><p>Back in 2013 I proposed
+<a href="http://people.skolelinux.org/pere/blog/_Electronic__paper_invoices___using_vCard_in_a_QR_code.html">a
+way to make paper and PDF invoices easier to process electronically by
+adding a QR code with the key information about the invoice</a>. I
+suggested using vCard field definition, to get some standard format
+for name and address, but any format would work. I did not do
+anything about the proposal, but hoped someone one day would make
+something like it. It would make it possible to efficiently send
+machine readable invoices directly between seller and buyer.</p>
+
+<p>This was the background when I came across a proposal and
+specification from the web based accounting and invoicing supplier
+<a href="http://www.visma.com/">Visma</a> in Sweden called
+<a href="http://usingqr.com/">UsingQR</a>. Their PDF invoices contain
+a QR code with the key information of the invoice in JSON format.
+This is the typical content of a QR code following the UsingQR
+specification (based on a real world example, some numbers replaced to
+get a more bogus entry). I've reformatted the JSON to make it easier
+to read. Normally this is all on one long line:</p>
+
+<p><img src="http://people.skolelinux.org/pere/blog/images/2016-03-19-qr-invoice.png" align="right"><pre>
+{
+ "vh":500.00,
+ "vm":0,
+ "vl":0,
+ "uqr":1,
+ "tp":1,
+ "nme":"Din Leverandør",
+ "cc":"NO",
+ "cid":"997912345 MVA",
+ "iref":"12300001",
+ "idt":"20151022",
+ "ddt":"20151105",
+ "due":2500.0000,
+ "cur":"NOK",
+ "pt":"BBAN",
+ "acc":"17202612345",
+ "bc":"BIENNOK1",
+ "adr":"0313 OSLO"
+}
+</pre></p>
+
+</p>The interpretation of the fields can be found in the
+<a href="http://usingqr.com/wp-content/uploads/2014/06/UsingQR_specification1.pdf">format
+specification</a> (revision 2 from june 2014). The format seem to
+have most of the information needed to handle accounting and payment
+of invoices, at least the fields I have needed so far here in
+Norway.</p>
+
+<p>Unfortunately, the site and document do not mention anything about
+the patent, trademark and copyright status of the format and the
+specification. Because of this, I asked the people behind it back in
+November to clarify. Ann-Christine Savlid (ann-christine.savlid (at)
+visma.com) replied that Visma had not applied for patent or trademark
+protection for this format, and that there were no copyright based
+usage limitations for the format. I urged her to make sure this was
+explicitly written on the web pages and in the specification, but
+unfortunately this has not happened yet. So I guess if there is
+submarine patents, hidden trademarks or a will to sue for copyright
+infringements, those starting to use the UsingQR format might be at
+risk, but if this happen there is some legal defense in the fact that
+the people behind the format claimed it was safe to do so. At least
+with patents, there is always
+<a href="http://www.paperspecs.com/paper-news/beware-the-qr-code-patent-trap/">a
+chance of getting sued...</a></p>
+
+<p>I also asked if they planned to maintain the format in an
+independent standard organization to give others more confidence that
+they would participate in the standardization process on equal terms
+with Visma, but they had no immediate plans for this. Their plan was
+to work with banks to try to get more users of the format, and
+evaluate the way forward if the format proved to be popular. I hope
+they conclude that using an open standard organisation like
+<a href="http://www.ietf.org/">IETF</a> is the correct place to
+maintain such specification.</p>

- <title>What would it cost to store all phone calls in Norway?</title>
- <link>http://people.skolelinux.org/pere/blog/What_would_it_cost_to_store_all_phone_calls_in_Norway_.html</link>
- <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/What_would_it_cost_to_store_all_phone_calls_in_Norway_.html</guid>
- <pubDate>Fri, 1 May 2015 19:30:00 +0200</pubDate>
- <description><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>

+ <description><p>Back in September, I blogged about
+<a href="http://people.skolelinux.org/pere/blog/The_life_and_death_of_a_laptop_battery.html">the
+system I wrote to collect statistics about my laptop battery</a>, and
+how it showed the decay and death of this battery (now replaced). I
+created a simple deb package to handle the collection and graphing,
+but did not want to upload it to Debian as there were already
+<a href="https://tracker.debian.org/pkg/battery-stats">a battery-stats
+package in Debian</a> that should do the same thing, and I did not see
+a point of uploading a competing package when battery-stats could be
+fixed instead. I reported a few bugs about its non-function, and
+hoped someone would step in and fix it. But no-one did.</p>
+
+<p>I got tired of waiting a few days ago, and took matters in my own
+hands. The end result is that I am now the new upstream developer of
+battery stats (<a href="https://github.com/petterreinholdtsen/battery-stats">available from github</a>) and part of the team maintaining
+battery-stats in Debian, and the package in Debian unstable is finally
+able to collect battery status using the <tt>/sys/class/power_supply/</tt>
+information provided by the Linux kernel. If you install the
+battery-stats package from unstable now, you will be able to get a
+graph of the current battery fill level, to get some idea about the
+status of the battery. The source package build and work just fine in
+Debian testing and stable (and probably oldstable too, but I have not
+tested). The default graph you get for that system look like this:</p>
+
+<p align="center"><img src="http://people.skolelinux.org/pere/blog/images/2016-03-15-battery-stats-graph-example.png" width="70%" align="center"></p>
+
+<p>My plans for the future is to merge my old scripts into the
+battery-stats package, as my old scripts collected a lot more details
+about the battery. The scripts are merged into the upstream
+battery-stats git repository already, but I am not convinced they work
+yet, as I changed a lot of paths along the way. Will have to test a
+bit more before I make a new release.</p>
+
+<p>I will also consider changing the file format slightly, as I
+suspect the way I combine several values into one field might make it
+impossible to know the type of the value when using it for processing
+and graphing.</p>
+
+<p>If you would like I would like to keep an close eye on your laptop
+battery, check out the battery-stats package in
+<a href="https://tracker.debian.org/pkg/battery-stats">Debian</a> and
+on
+<a href="https://github.com/petterreinholdtsen/battery-stats">github</a>.
+I would love some help to improve the system further.</p>

+ <description><p>Making packages for Debian requires quite a lot of attention to
+details. And one of the details is the content of the
+debian/copyright file, which should list all relevant licenses used by
+the code in the package in question, preferably in
+<a href="https://www.debian.org/doc/packaging-manuals/copyright-format/1.0/">machine
+readable DEP5 format</a>.</p>
+
+<p>For large packages with lots of contributors it is hard to write
+and update this file manually, and if you get some detail wrong, the
+package is normally rejected by the ftpmasters. So getting it right
+the first time around get the package into Debian faster, and save
+both you and the ftpmasters some work.. Today, while trying to figure
+out what was wrong with
+<a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=686447">the
+zfsonlinux copyright file</a>, I decided to spend some time on
+figuring out the options for doing this job automatically, or at least
+semi-automatically.</p>
+
+<p>Lucikly, there are at least two tools available for generating the
+file based on the code in the source package,
+<tt><a href="https://tracker.debian.org/pkg/debmake">debmake</a></tt>
+and <tt><a href="https://tracker.debian.org/pkg/cme">cme</a></tt>. I'm
+not sure which one of them came first, but both seem to be able to
+create a sensible draft file. As far as I can tell, none of them can
+be trusted to get the result just right, so the content need to be
+polished a bit before the file is OK to upload. I found the debmake
+option in
+<a href="http://goofying-with-debian.blogspot.com/2014/07/debmake-checking-source-against-dep-5.html">a
+blog posts from 2014</a>.
+
+<p>To generate using debmake, use the -cc option:
+
+<p><pre>
+debmake -cc > debian/copyright
+</pre></p>
+
+<p>Note there are some problems with python and non-ASCII names, so
+this might not be the best option.</p>
+
+<p>The cme option is based on a config parsing library, and I found
+this approach in
+<a href="https://ddumont.wordpress.com/2015/04/05/improving-creation-of-debian-copyright-file/">a
+blog post from 2015</a>. To generate using cme, use the 'update
+dpkg-copyright' option:
+
+<p><pre>
+cme update dpkg-copyright
+</pre></p>
+
+<p>This will create or update debian/copyright. The cme tool seem to
+handle UTF-8 names better than debmake.</p>
+
+<p>When the copyright file is created, I would also like some help to
+check if the file is correct. For this I found two good options,
+<tt>debmake -k</tt> and <tt>license-reconcile</tt>. The former seem
+to focus on license types and file matching, and is able to detect
+ineffective blocks in the copyright file. The latter reports missing
+copyright holders and years, but was confused by inconsistent license
+names (like CDDL vs. CDDL-1.0). I suspect it is good to use both and
+fix all issues reported by them before uploading. But I do not know
+if the tools and the ftpmasters agree on what is important to fix in a
+copyright file, so the package might still be rejected.</p>
+
+<p>The devscripts tool <tt>licensecheck</tt> deserve mentioning. It
+will read through the source and try to find all copyright statements.
+It is not comparing the result to the content of debian/copyright, but
+can be useful when verifying the content of the copyright file.</p>
+
+<p>Are you aware of better tools in Debian to create and update
+debian/copyright file. Please let me know, or blog about it on
+planet.debian.org.</p>
+
+<p>As usual, if you use Bitcoin and want to show your support of my
+activities, please send Bitcoin donations to my address
+<b><a href="bitcoin:15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b">15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b</a></b>.</p>
+
+<p><strong>Update 2016-02-20</strong>: I got a tip from Mike Gabriel
+on how to use licensecheck and cdbs to create a draft copyright file
+
+<p><pre>
+licensecheck --copyright -r `find * -type f` | \
+ /usr/lib/cdbs/licensecheck2dep5 > debian/copyright.auto
+</pre></p>
+
+<p>He mentioned that he normally check the generated file into the
+version control system to make it easier to discover license and
+copyright changes in the upstream source. I will try to do the same
+with my packages in the future.</p>
+
+<p><strong>Update 2016-02-21</strong>: The cme author recommended
+against using -quiet for new users, so I removed it from the proposed
+command line.</p>

+ <description><p>The <a href="https://wiki.debian.org/DEP-11">appstream system</a>
+is taking shape in Debian, and one provided feature is a very
+convenient way to tell you which package to install to make a given
+firmware file available when the kernel is looking for it. This can
+be done using apt-file too, but that is for someone else to blog
+about. :)</p>
+
+<p>Here is a small recipe to find the package with a given firmware
+file, in this example I am looking for ctfw-3.2.3.0.bin, randomly
+picked from the set of firmware announced using appstream in Debian
+unstable. In general you would be looking for the firmware requested
+by the kernel during kernel module loading. To find the package
+providing the example file, do like this:</p>
-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.
+<blockquote><pre>
+% apt install appstream
+[...]
+% apt update
+[...]
+% appstreamcli what-provides firmware:runtime ctfw-3.2.3.0.bin | \
+ awk '/Package:/ {print $2}'
+firmware-qlogic
+%
+</pre></blockquote>
-== About Debian ==
+<p>See <a href="https://wiki.debian.org/AppStream/Guidelines">the
+appstream wiki</a> page to learn how to embed the package metadata in
+a way appstream can use.</p>
-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.
+<p>This same approach can be used to find any package supporting a
+given MIME type. This is very useful when you get a file you do not
+know how to handle. First find the mime type using <tt>file
+--mime-type</tt>, and next look up the package providing support for
+it. Lets say you got an SVG file. Its MIME type is image/svg+xml,
+and you can find all packages handling this type like this:</p>
-== Thanks ==
+<blockquote><pre>
+% apt install appstream
+[...]
+% apt update
+[...]
+% appstreamcli what-provides mimetype image/svg+xml | \
+ awk '/Package:/ {print $2}'
+bkchem
+phototonic
+inkscape
+shutter
+tetzle
+geeqie
+xia
+pinta
+gthumb
+karbon
+comix
+mirage
+viewnior
+postr
+ristretto
+kolourpaint4
+eog
+eom
+gimagereader
+midori
+%
+</pre></blockquote>
-Thanks to everyone making Debian and Debian Edu / Skolelinux happen!
-You rock.
-</pre>
+<p>I believe the MIME types are fetched from the desktop file for
+packages providing appstream metadata.</p>

- <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Shirish_Agarwal.html</guid>
- <pubDate>Wed, 15 Apr 2015 09:20:00 +0200</pubDate>
- <description><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>

+ <description><p>Most people seem not to realise that every time they walk around
+with the computerised radio beacon known as a mobile phone their
+position is tracked by the phone company and often stored for a long
+time (like every time a SMS is received or sent). And if their
+computerised radio beacon is capable of running programs (often called
+mobile apps) downloaded from the Internet, these programs are often
+also capable of tracking their location (if the app requested access
+during installation). And when these programs send out information to
+central collection points, the location is often included, unless
+extra care is taken to not send the location. The provided
+information is used by several entities, for good and bad (what is
+good and bad, depend on your point of view). What is certain, is that
+the private sphere and the right to free movement is challenged and
+perhaps even eradicated for those announcing their location this way,
+when they share their whereabouts with private and public
+entities.</p>
+
+<p align="center"><img width="70%" src="http://people.skolelinux.org/pere/blog/images/2016-01-24-nice-creepy-desktop-window.png"></p>
+
+<p>The phone company logs provide a register of locations to check out
+when one want to figure out what the tracked person was doing. It is
+unavailable for most of us, but provided to selected government
+officials, company staff, those illegally buying information from
+unfaithful servants and crackers stealing the information. But the
+public information can be collected and analysed, and a free software
+tool to do so is called
+<a href="http://www.geocreepy.com/">Creepy or Cree.py</a>. I
+discovered it when I read
+<a href="http://www.aftenposten.no/kultur/Slik-kan-du-bli-overvaket-pa-Twitter-og-Instagram-uten-a-ane-det-7787884.html">an
+article about Creepy</a> in the Norwegian newspaper Aftenposten i
+November 2014, and decided to check if it was available in Debian.
+The python program was in Debian, but
+<a href="https://tracker.debian.org/pkg/creepy">the version in
+Debian</a> was completely broken and practically unmaintained. I
+uploaded a new version which did not work quite right, but did not
+have time to fix it then. This Christmas I decided to finally try to
+get Creepy operational in Debian. Now a fixed version is available in
+Debian unstable and testing, and almost all Debian specific patches
+are now included
+<a href="https://github.com/jkakavas/creepy">upstream</a>.</p>
+
+<p>The Creepy program visualises geolocation information fetched from
+Twitter, Instagram, Flickr and Google+, and allow one to get a
+complete picture of every social media message posted recently in a
+given area, or track the movement of a given individual across all
+these services. Earlier it was possible to use the search API of at
+least some of these services without identifying oneself, but these
+days it is impossible. This mean that to use Creepy, you need to
+configure it to log in as yourself on these services, and provide
+information to them about your search interests. This should be taken
+into account when using Creepy, as it will also share information
+about yourself with the services.</p>
+
+<p>The picture above show the twitter messages sent from (or at least
+geotagged with a position from) the city centre of Oslo, the capital
+of Norway. One useful way to use Creepy is to first look at
+information tagged with an area of interest, and next look at all the
+information provided by one or more individuals who was in the area.
+I tested it by checking out which celebrity provide their location in
+twitter messages by checkout out who sent twitter messages near a
+Norwegian TV station, and next could track their position over time,
+making it possible to locate their home and work place, among other
+things. A similar technique have been
+<a href="http://www.buzzfeed.com/maxseddon/does-this-soldiers-instagram-account-prove-russia-is-covertl">used
+to locate Russian soldiers in Ukraine</a>, and it is both a powerful
+tool to discover lying governments, and a useful tool to help people
+understand the value of the private information they provide to the
+public.</p>
+
+<p>The package is not trivial to backport to Debian Stable/Jessie, as
+it depend on several python modules currently missing in Jessie (at
+least python-instagram, python-flickrapi and
+python-requests-toolbelt).</p>
+
+<p>(I have uploaded
+<a href="https://screenshots.debian.net/package/creepy">the image to
+screenshots.debian.net</a> and licensed it under the same terms as the
+Creepy program in Debian.)</p>

+ <description><p>During his DebConf15 keynote, Jacob Appelbaum
+<a href="https://summit.debconf.org/debconf15/meeting/331/what-is-to-be-done/">observed
+that those listening on the Internet lines would have good reason to
+believe a computer have a given security hole</a> if it download a
+security fix from a Debian mirror. This is a good reason to always
+use encrypted connections to the Debian mirror, to make sure those
+listening do not know which IP address to attack. In August, Richard
+Hartmann observed that encryption was not enough, when it was possible
+to interfere download size to security patches or the fact that
+download took place shortly after a security fix was released, and
+<a href="http://richardhartmann.de/blog/posts/2015/08/24-Tor-enabled_Debian_mirror/">proposed
+to always use Tor to download packages from the Debian mirror</a>. He
+was not the first to propose this, as the
+<tt><a href="https://tracker.debian.org/pkg/apt-transport-tor">apt-transport-tor</a></tt>
+package by Tim Retout already existed to make it easy to convince apt
+to use <a href="https://www.torproject.org/">Tor</a>, but I was not
+aware of that package when I read the blog post from Richard.</p>
+
+<p>Richard discussed the idea with Peter Palfrader, one of the Debian
+sysadmins, and he set up a Tor hidden service on one of the central
+Debian mirrors using the address vwakviie2ienjx6t.onion, thus making
+it possible to download packages directly between two tor nodes,
+making sure the network traffic always were encrypted.</p>
+
+<p>Here is a short recipe for enabling this on your machine, by
+installing <tt>apt-transport-tor</tt> and replacing http and https
+urls with tor+http and tor+https, and using the hidden service instead
+of the official Debian mirror site. I recommend installing
+<tt>etckeeper</tt> before you start to have a history of the changes
+done in /etc/.</p>
+
+<blockquote><pre>
+apt install apt-transport-tor
+sed -i 's% http://ftp.debian.org/% tor+http://vwakviie2ienjx6t.onion/%' /etc/apt/sources.list
+sed -i 's% http% tor+http%' /etc/apt/sources.list
+</pre></blockquote>
+
+<p>If you have more sources listed in /etc/apt/sources.list.d/, run
+the sed commands for these too. The sed command is assuming your are
+using the ftp.debian.org Debian mirror. Adjust the command (or just
+edit the file manually) to match your mirror.</p>
+
+<p>This work in Debian Jessie and later. Note that tools like
+<tt>apt-file</tt> only recently started using the apt transport
+system, and do not work with these tor+http URLs. For
+<tt>apt-file</tt> you need the version currently in experimental,
+which need a recent apt version currently only in unstable. So if you
+need a working <tt>apt-file</tt>, this is not for you.</p>
+
+<p>Another advantage from this change is that your machine will start
+using Tor regularly and at fairly random intervals (every time you
+update the package lists or upgrade or install a new package), thus
+masking other Tor traffic done from the same machine. Using Tor will
+become normal for the machine in question.</p>
+
+<p>On <a href="https://wiki.debian.org/FreedomBox">Freedombox</a>, APT
+is set up by default to use <tt>apt-transport-tor</tt> when Tor is
+enabled. It would be great if it was the default on any Debian
+system.</p>

-The purpose is to document the talks and spread them to a wider

-Since a few days ago, when I figured out the

+ <description><p>When I was a kid, we used to collect "car numbers", as we used to
+call the car license plate numbers in those days. I would write the
+numbers down in my little book and compare notes with the other kids
+to see how many region codes we had seen and if we had seen some
+exotic or special region codes and numbers. It was a fun game to pass
+time, as we kids have plenty of it.</p>
+
+<p>A few days I came across
+<a href="https://github.com/openalpr/openalpr">the OpenALPR
+project</a>, a free software project to automatically discover and
+report license plates in images and video streams, and provide the
+"car numbers" in a machine readable format. I've been looking for
+such system for a while now, because I believe it is a bad idea that the
+<a href="https://en.wikipedia.org/wiki/Automatic_number_plate_recognition">automatic
+number plate recognition</a> tool only is available in the hands of
+the powerful, and want it to be available also for the powerless to
+even the score when it comes to surveillance and sousveillance. I
+discovered the developer
+<a href="https://bugs.debian.org/747509">wanted to get the tool into
+Debian</a>, and as I too wanted it to be in Debian, I volunteered to
+help him get it into shape to get the package uploaded into the Debian
+archive.</p>
+
+<p>Today we finally managed to get the package into shape and uploaded
+it into Debian, where it currently
+<a href="https://ftp-master.debian.org//new/openalpr_2.2.1-1.html">waits
+in the NEW queue</a> for review by the Debian ftpmasters.</p>
+
+<p>I guess you are wondering why on earth such tool would be useful
+for the common folks, ie those not running a large government
+surveillance system? Well, I plan to put it in a computer on my bike
+and in my car, tracking the cars nearby and allowing me to be notified
+when number plates on my watch list are discovered. Another use case
+was suggested by a friend of mine, who wanted to set it up at his home
+to open the car port automatically when it discovered the plate on his
+car. When I mentioned it perhaps was a bit foolhardy to allow anyone
+capable of placing his license plate number of a piece of cardboard to
+open his car port, men replied that it was always unlocked anyway. I
+guess for such use case it make sense. I am sure there are other use
+cases too, for those with imagination and a vision.</p>
+
+<p>If you want to build your own version of the Debian package, check
+out the upstream git source and symlink ./distros/debian to ./debian/
+before running "debuild" to build the source. Or wait a bit until the
+package show up in unstable.</p>

- <description><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>
-
-<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

+ <pubDate>Sun, 20 Dec 2015 12:20:00 +0100</pubDate>
+ <description><p>Around three years ago, I created
+<a href="http://packages.qa.debian.org/isenkram">the isenkram
+system</a> to get a more practical solution in Debian for handing
+hardware related packages. A GUI system in the isenkram package will
+present a pop-up dialog when some hardware dongle supported by
+relevant packages in Debian is inserted into the machine. The same
+lookup mechanism to detect packages is available as command line
+tools in the isenkram-cli package. In addition to mapping hardware,
+it will also map kernel firmware files to packages and make it easy to
+install needed firmware packages automatically. The key for this
+system to work is a good way to map hardware to packages, in other
+words, allow packages to announce what hardware they will work
+with.</p>
+
+<p>I started by providing data files in the isenkram source, and
+adding code to download the latest version of these data files at run
+time, to ensure every user had the most up to date mapping available.
+I also added support for storing the mapping in the Packages file in
+the apt repositories, but did not push this approach because while I
+was trying to figure out how to best store hardware/package mappings,
+<a href="http://www.freedesktop.org/software/appstream/docs/">the
+appstream system</a> was announced. I got in touch and suggested to
+add the hardware mapping into that data set to be able to use
+appstream as a data source, and this was accepted at least for the
+Debian version of appstream.</p>
+
+<p>A few days ago using appstream in Debian for this became possible,
+and today I uploaded a new version 0.20 of isenkram adding support for
+appstream as a data source for mapping hardware to packages. The only
+package so far using appstream to announce its hardware support is my
+pymissile package. I got help from Matthias Klumpp with figuring out
+how do add the required
+<a href="https://appstream.debian.org/html/sid/main/metainfo/pymissile.html">metadata
+in pymissile</a>. I added a file debian/pymissile.metainfo.xml with
+this content:</p>
+
+<blockquote><pre>
+&lt;?xml version="1.0" encoding="UTF-8"?&gt;
+&lt;component&gt;
+ &lt;id&gt;pymissile&lt;/id&gt;
+ &lt;metadata_license&gt;MIT&lt;/metadata_license&gt;
+ &lt;name&gt;pymissile&lt;/name&gt;
+ &lt;summary&gt;Control original Striker USB Missile Launcher&lt;/summary&gt;
+ &lt;description&gt;
+ &lt;p&gt;
+ Pymissile provides a curses interface to control an original
+ Marks and Spencer / Striker USB Missile Launcher, as well as a
+ motion control script to allow a webcamera to control the
+ launcher.
+ &lt;/p&gt;
+ &lt;/description&gt;
+ &lt;provides&gt;
+ &lt;modalias&gt;usb:v1130p0202d*&lt;/modalias&gt;
+ &lt;/provides&gt;
+&lt;/component&gt;
+</pre></blockquote>
+
+<p>The key for isenkram is the component/provides/modalias value,
+which is a glob style match rule for hardware specific strings
+(modalias strings) provided by the Linux kernel. In this case, it
+will map to all USB devices with vendor code 1130 and product code
+0202.</p>
+
+<p>Note, it is important that the license of all the metadata files
+are compatible to have permissions to aggregate them into archive wide
+appstream files. Matthias suggested to use MIT or BSD licenses for
+these files. A challenge is figuring out a good id for the data, as
+it is supposed to be globally unique and shared across distributions
+(in other words, best to coordinate with upstream what to use). But
+it can be changed later or, so we went with the package name as
+upstream for this project is dormant.</p>
+
+<p>To get the metadata file installed in the correct location for the
+mirror update scripts to pick it up and include its content the
+appstream data source, the file must be installed in the binary
+package under /usr/share/appdata/. I did this by adding the following
+line to debian/pymissile.install:</p>
<blockquote><pre>
-./ffmpeg2theora.linux &lt;OBE_gemini_URL.ts&gt; -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 &lt;pw&gt; /frikanalen.ogv
+debian/pymissile.metainfo.xml usr/share/appdata
</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>
+<p>With that in place, the command line tool isenkram-lookup will list
+all packages useful on the current computer automatically, and the GUI
+pop-up handler will propose to install the package not already
+installed if a hardware dongle is inserted into the machine in
+question.</p>
+
+<p>Details of the modalias field in appstream is available from the
+<a href="https://wiki.debian.org/DEP-11">DEP-11</a> proposal.</p>
+
+<p>To locate the modalias values of all hardware present in a machine,
+try running this command on the command line:</p>
+
+<blockquote><pre>
+cat $(find /sys/devices/|grep modalias)
+</pre></blockquote>

- <title>En enklere Osloskolehverdag med automatisk sjekk av Fronter</title>

- <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/En_enklere_Osloskolehverdag_med_automatisk_sjekk_av_Fronter.html</guid>
- <pubDate>Thu, 12 Feb 2015 10:30:00 +0100</pubDate>
- <description><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>

+
+<p>Jeg ble gledelig overrasket i dag da jeg oppdaget at boken jeg har
+gitt ut
+<a href="https://www.amazon.com/Fri-kultur-Norwegian-Lawrence-Lessig/dp/8269018236/">hadde
+dukket opp i Amazon</a>. Jeg hadde trodd det skulle ta lenger tid, da
+jeg fikk beskjed om at det skulle ta seks til åtte uker.
+Amazonoppføringen er et resultat av at jeg for noen uker siden
+diskuterte prissetting og håndtering av profitt med forfatteren. Det
+måtte avklares da bruksvilkårene til boken har krav om
+ikke-kommersiell bruk. Vi ble enige om at overskuddet fra salg av
+boken skal sendes til
+<a href="https://creativecommons.org/">Creative Commons-stiftelsen</a>.
+Med det på plass kunne jeg be
+<a href="https://www.lulu.com/shop/lawrence-lessig/fri-kultur/paperback/product-22441576.html">lulu.com</a>
+om å gi boken «utvidet» distribusjon. Årsaken til at
+bokhandeldistribusjon var litt utfordrende er at bokhandlere krever
+mulighet for profitt på bøkene de selger (selvfølgelig), og dermed
+måtte de få lov til å selge til høyere pris enn lulu.com. I tillegg
+er det krav om samme pris på lulu.com og i bokhandlene, dermed blir
+prisen økt også hos lulu.com. Hva skulle jeg gjøre med den profitten
+uten å bryte med klausulen om ikkekommersiell? Løsningen var å gi
+bort profitten til CC-stiftelsen. Prisen på boken ble nesten
+tredoblet, til $19.99 (ca. 160,-) pluss frakt, men synligheten øker
+betraktelig når den kan finnes i katalogene til store nettbokhandlere.
+Det betyr at hvis du allerede har kjøpt boken har du fått den veldig
+billig, og kjøper du den nå, får du den fortsatt billig samt donerer i
+tillegg noen tiere til fremme av Creative Commons.</p>
+
+<p>Mens jeg var i gang med å titte etter informasjon om boken
+oppdaget jeg at den også var dukket opp på
+<a href="https://books.google.no/books?id=uKUGCwAAQBAJ">Google
+Books</a>, der en kan lese den på web. PDF-utgaven har ennå ikke
+dukket opp hos <a href="https://www.nb.no/">Nasjonalbiblioteket</a>,
+men det regner jeg med kommer på plass i løpet av noen uker. Boken er
+heller ikke dukket opp hos
+<a href="https://www.barnesandnoble.com/">Barnes & Noble</a> ennå, men
+jeg antar det bare er et tidsspørsmål før dette er på plass.</p>
+
+<p>Boken er dessverre ikke tilgjengelig fra norske bokhandlere, og
+kommer neppe til å bli det med det første. Årsaken er at for å få det
+til måtte jeg personlig håndtere bestilling av bøker, hvilket jeg ikke
+er interessert i å bruke tid på. Jeg kunne betalt ca 2000,- til
+<a href="http://www.bokbasen.no/">den norske bokbasen</a>, en felles
+database over bøker tilgjengelig for norske bokhandlere, for å få en
+oppføring der, men da måtte jeg tatt imot bestillinger på epost og
+sendt ut bøker selv. Det ville krevd at jeg var klar til å
+sende ut bøker på kort varsel, dvs. holdt meg med ekstra bøker,
+konvolutter og frimerker. Bokbasen har visst ikke opplegg for å be
+bokhandlene bestille direkte via web, så jeg droppet oppføring der.
+Jeg har spurt Haugen bok og Tronsmo direkte på epost om de er
+interessert i å ta inn boken i sin bestillingskatalog, men ikke fått
+svar, så jeg antar de ikke er interessert. Derimot har jeg fått en
+hyggelig henvendelse fra Biblioteksentralen som fortalte at de har
+lagt den inn i sin database slik at deres bibliotekskunder enkelt kan
+bestille den via dem.</p>
+
+<p>Boken er i følge
+<a href="http://bibsys-almaprimo.hosted.exlibrisgroup.com/primo_library/libweb/action/display.do?tabs=detailsTab&ct=display&fn=search&doc=BIBSYS_ILS71518423420002201&indx=1&recIds=BIBSYS_ILS71518423420002201&recIdxs=0&elementId=0&renderMode=poppedOut&displayMode=full&frbrVersion=&dscnt=0&tab=library_catalogue&dstmp=1448543801124&vl(freeText0)=fri%20kultur&vid=UBO&mode=Basic">Bibsys/Oria</a>
+og bokdatabasen til
+<a href="https://www.deich.folkebibl.no/cgi-bin/websok?tnr=1819617">Deichmanske</a>
+tilgjengelig fra flere biblioteker allerede, og alle eksemplarer er
+visst allerede utlånt med ventetid. Det synes jeg er veldig gledelig
+å se. Jeg håper mange kommer til å lese boken. Jeg tror den er
+spesielt egnet for foreldre og bekjente av oss nerder for å forklare
+hva slags problemer vi ser med dagens opphavsrettsregime.</p>
