-announcement today</a>:</p>
-
-<pre>
-the Debian Edu / Skolelinux project is pleased to announce the first
-*beta* release of Debian Edu "Jessie" 8.0+edu0~b1, which for the first
-time is composed entirely of packages from the current Debian stable
-release, Debian 8 "Jessie".
-
-(As most reading this will know, Debian "Jessie" hasn't actually been
-released by now. The release is still in progress but should finish
-later today ;)
-
-We expect to make a final release of Debian Edu "Jessie" in the coming
-weeks, timed with the first point release of Debian Jessie. Upgrades
-from this beta release of Debian Edu Jessie to the final release will
-be possible and encouraged!
-
-Please report feedback to debian-edu@lists.debian.org and/or submit
-bugs: http://wiki.debian.org/DebianEdu/HowTo/ReportBugs
-
-Debian Edu - sometimes also known as "Skolelinux" - is a complete
-operating system for schools, universities and other
-organisations. Through its pre- prepared installation profiles
-administrators can install servers, workstations and laptops which
-will work in harmony on the school network. With Debian Edu, the
-teachers themselves or their technical support staff can roll out a
-complete multi-user, multi-machine study environment within hours or
-days.
-
-Debian Edu is already in use at several hundred schools all over the
-world, particularly in Germany, Spain and Norway. Installations come
-with hundreds of applications pre-installed, plus the whole Debian
-archive of thousands of compatible packages within easy reach.
-
-For those who want to give Debian Edu Jessie a try, download and
-installation instructions are available, including detailed
-instructions in the manual explaining the first steps, such as setting
-up a network or adding users. Please note that the password for the

-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.

- <title>Debian Edu interview: Shirish Agarwal</title>
- <link>http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Shirish_Agarwal.html</link>
- <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>

+ <title>UsingQR - "Electronic" paper invoices using JSON and QR codes</title>
+ <link>http://people.skolelinux.org/pere/blog/UsingQR____Electronic__paper_invoices_using_JSON_and_QR_codes.html</link>
+ <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>
