Second alpha release of Debian Edu / Skolelinux based on Debian Wheezy
+
14th May 2013
+

The Debian Edu / Skolelinux +project is making great progress and made its second Wheezy based +release today. This is the release announcement:

+ +

New features for Debian Edu 7.0.0 alpha1 released +2013-05-14

+ +

This is the release notes for for Debian Edu / Skolelinux 7.0.0 edu +alpha1, based on Debian with codename "Wheezy".

+ +

About Debian Edu and 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. Immediatly 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, DVD or USB stick all +other machines can be installed via the network.

+ +

This is the first test release based on Wheezy (which currently is +not released yet). Basically this is an updated and slightly improved +version compared to the Squeeze release.

Debian, the Linux distribution of choice for LEGO designers?
+
11th May 2013
+

In January, +I +announced a new IRC +channel #debian-lego, for those of us in the Debian and Linux +community interested in LEGO, the +marvellous construction system from Denmark. We also created +a wiki page to have +a place to take notes and write down our plans and hopes. And several +people showed up to help. I was very happy to see the effect of my +call. Since the small start, we have a debtags tag +hardware::hobby:lego +tag for LEGO related packages, and now count 10 packages related to +LEGO and Mindstorms:

+ +

+ + + + + + + + + + +
brickosalternative OS for LEGO Mindstorms RCX. Supports development in C/C++
leocadvirtual brick CAD software
libnxtutility library for talking to the LEGO Mindstorms NX
lnpddaemon for LNP communication with BrickOS
nbccompiler for LEGO Mindstorms NXT bricks
nqcNot Quite C compiler for LEGO Mindstorms RCX
python-nxtpython driver/interface/wrapper for the Lego Mindstorms NXT robot
python-nxt-filersimple GUI to manage files on a LEGO Mindstorms NXT
scratcheasy to use programming environment for ages 8 and up
t2nsimple command-line tool for Lego NXT

+ +

Some of these are available in Wheezy, and all but one are +currently available in Jessie/testing. leocad is so far only +available in experimental.

+ +

If you care about LEGO in Debian, please join us on IRC and help +adding the rest of the great free software tools available on Linux +for LEGO designers.

Narvik sparer minst 9 millioner på å bruke Skolelinux
+
10th May 2013
+

I fjor sommer ble jeg +gledelig +overrasket over et oppslag i avisen Fremover om Narvik kommunes +bruk av Skolelinux. Oppslaget +var basert på et notat som besvarte spørsmål fra ordfører Tor Nysæter +og rådgiver for skolesektoren, Petter Falkbu, om bruken av Skolelinux +i Narvikskolene og konstnaden ved å gå over til Windows. For litt +over en uke siden siden fikk jeg endelig bedt kommunen om å få innsyn +i dette notatet, og det ble oversendt på epost tirsdag. Jeg fikk +lagt +ut notatet samme dag, og fikk i dag sjekket postlista til Narvik, +der jeg fant notatet som +sak +2013/1023.

+ +

Notatet forteller at Narvik ville måtte betalt minst 9 millioner +for å gå over til Windows på skolene. I tillegg dokumenterer notatet +at læreplanens krav oppfylles uten problemer ved bruk av Skolelinux. +Jeg anbefaler alle å lese de 10 sidene med gode argumenter for å kutte +unødige utgifter på IT i skoleverket. :)

Debian Wheezy is out - and Debian Edu / Skolelinux should soon follow! #newinwheezy
+
5th May 2013
+

When I woke up this morning, I was very happy to see that the +release announcement +for Debian Wheezy was waiting in my mail box. This is a great +Debian release, and I expect to move my machines at home over to it fairly +soon.

+ +

The new debian release contain heaps of new stuff, and one program +in particular make me very happy to see included. The +Scratch program, made famous by +the Teach kids code movement, is +included for the first time. Alongside similar programs like +kturtle and +turtleart, +it allow for visual programming where syntax errors can not happen, +and a friendly programming environment for learning to control the +computer. Scratch will also be included in the next release of Debian +Edu. + +

And now that Wheezy is wrapped up, we can wrap up the next Debian +Edu/Skolelinux release too. The +first +alpha release went out last week, and the next should soon +follow.

Isenkram 0.2 finally in the Debian archive
-
3rd April 2013
-

Today the Isenkram -package finally made it into the archive, after lingering in NEW -for many months. I uploaded it to the Debian experimental suite -2013-01-27, and today it was accepted into the archive.

- -

Isenkram is a system for suggesting to users what packages to -install to work with a pluggable hardware device. The suggestion pop -up when the device is plugged in. For example if a Lego Mindstorm NXT -is inserted, it will suggest to install the program needed to program -the NXT controller. Give it a go, and report bugs and suggestions to -BTS. :)

EFN nyutgir novellen Kodémus av Tor Åge Bringsværd
-
27th March 2013
-

For noen dager siden nevnte jeg at vi jobbet med å typesette en -novelle med DocBook. I dag ble -utgivelsen annonsert med følgende pressemelding fra Elektronisk -Forpost Norge), som jeg gjengir i sin helhet:

- -

- -

EFN nyutgir Kodémus:

- -

Tor Åge Bringsværd-novelle om IT og overvåkning fra -informasjonsteknologiens spedbarndom får nytt liv

- -

Elektronisk Forpost Norge (EFN) er veldig glad for anledningen til -å nyutgi Tor Åge Bringsværds novelle Kodémus i digitalt format for nye -(og gamle) generasjoner. Novellen ble skrevet så tidlig som vinteren -1968, og første gang trykt i novellesamlingen Probok på Gyldendal -samme år.

- -

Informasjonsteknologi spiller en sentral rolle i Kodémus, og det er -spennende å sammenligne beskrivelsen av IT fra 1968 med dagens IT i -2013. Forskjellene er mange -- men det er jammen likhetene også. Ikke -minst det at idag går jo nesten alle rundt med lillebrødre på seg!

- -

"Riktignok er det ikke påbudt å ha mobil," sier Thomas Gramstad, -leder i EFN. "Men vi holder på å lage et samfunn der det blir så -upraktisk eller tungvint å ikke ha det, at man i praksis ikke slipper -unna. Og disse lillebrødrene sladrer hele tiden til staten (og til -mange andre) om hvor vi er, hva vi gjør, hva vi bryr oss om, hva vi -liker..."

- -

Det at Kodémus åpenbart er skrevet i en annen tid med en annen type -IT og likevel virker så relevant idag, er i seg selv et hardtslående -tankekors.

- -

Tross sitt IT-tema fantes ikke Kodémus i elektronisk form, og -frivillige i EFN har skannet inn, OCR-tolket og korrekturlest -novellen, og deretter kodet den i en rekke digitale formater.

- -

Forfatteren har gitt tillatelse til publisering av Kodémus under ny -lisens, og novellen utgis av EFN med en Creative Commons (CC) -fribrukslisens (nærmere bestemt lisensen CC-BY-NC-ND). For leserne -eller brukerne innebærer dette at de får en klar og standardisert -beskjed om hvilke rettigheter de har til å dele novellen videre med -andre. For forfatteren innebærer dette økt synlighet og -tilgjengelighet for verket, slik at det ikke blir glemt, da -søkemotorer og nettlesere inneholder egne søkevalg for CC-lisenser, og -mange brukere søker etter verk som de vet de kan dele og bruke på -lovlig vis.

- -

EFN oppfordrer andre forfattere om å gi ut sine gamle tekster med -en fribrukslisens, slik at tekstene ikke blir glemt og for å stimulere -lovlig deling på nettet. EFN kan være behjelpelig med digitalisering -og utlegging på nett, i den grad det finnes kapasitet blant EFNs -medlemmer til dette. Vi mener at nyutgivelser av tekster under frie -lisenser kan øke interessen rundt forfatterskapet, og vil gjerne bidra -til dette.

- -

EFN utgir og deler med dette en novelle fra den digitale -informasjonsteknologiens tidligste barndom. En novelle som fortsatt er -full av vitalitet og aktualitet, og som derfor kan bidra til, og gi -ettertanke i dagens debatter om IT, personvern, overvåkning og -individets frihet og integritet.

- -

Du finner novellen her: -
http://efn.no/kodemus/

- -

i flere forskjellige formater, for ulike plattformer. Per idag -finnes novellen i disse formatene: EPUB, MOBI, XML, HTML, PDF og -txt. Det kan bli flere formater senere, og evt. frivillige -bidragsytere til dette er velkommen.

- -

Jeg håper flere forfattere ser verdien av å gjøre kulturen -tilgjengelig for flere, og slår følge med Hr. Bringsværd i å gi ut -sine verker med bruksvilkår med færre bruksbegrensinger enn -opphavsretten legger opp til. Selv om jeg gjerne skulle sett at han -hadde brukt en Creative Commons-lisens som tillot avledede verker og -kommersiell bruk.

Change the font, save the world (and save some money in the process)
-
26th March 2013
-

Would you like to help the environment and save money at the same -time, without much sacrifice? A small step could be to change the -font you use when printing.

- -

Three years ago, -Ars -Technica reported how the University of Wisconsin-Green Bay -changed their default front from -Arial to -Century -Gothic to save money. The Century Gothic font uses 30% less toner -than Arial to print the same text. In other word, you could cut your -toner costs by 30% (or actually, increase your toner supply life time -by more than 30%), by simply changing the default font used in your -prints.

- -

But it is not quite obvious how much one will save by switching. -The University of Wisconsin-Green Bay said it used $100,000 per year -on ink and toner cartridges, according to -a report from -TwinCities.com, and expected to save between $5,000 and $10,000 -per year by asking staff and students to use a different font. Not -all PDFs and documents are created internally, and those from external -sources will most likely still use a different font. Also, the -Century Gothic font is slightly wider than Arial, and thus might use -more sheets of paper to print the same text, so the total saving -depend on the documents printed.

- -

But it is definitely something to consider, if you want to reduce -the amount of trash, decrease the amount of toner used in the world, -and save some money in the process.

- -

Update 2013-04-10: If you want to know how much ink/toner could be -saved when switching between fonts, Inkfarm got a -service to calculate the -difference between font pairs. They also -recommend -which fonts to use to save ink. Check it out. :) While updating -this blog post, I also came across a blog post from InkCloners, -listing -the fonts they recommend, with Centory Gothic at the top.

Typesetting a short story using docbook for PDF, HTML and EPUB
-
24th March 2013
-

A few days ago, during a discussion in -EFN about interesting books to read -about copyright and the data retention directive, a suggestion to read -the 1968 short story Kodémus by -Tore Åge Bringsværd -came up. The text was only available in old paper books, and thus not -easily available for current and future generations. Some of the -people participating in the discussion contacted the author, and -reported back 2013-03-19 that the author was OK with releasing the -short story using a Creative -Commons license. The text was quickly scanned and OCR-ed, and we -were ready to start on the editing and typesetting.

- -

As I already had some experience formatting text in my project to -provide a Norwegian version of the Free Culture book by Lawrence -Lessig, I chipped in and set up a -DocBook processing framework to -generate PDF, HTML and EPUB version of the short story. The tools to -transform DocBook to different formats are already in my Linux -distribution of choice, Debian, so -all I had to do was to use the -dblatex, -dbtoepub -and xmlto tools to do the -conversion. After a few days, we decided to replace dblatex with -xsltproc/fop (aka -docbook-xsl), -to get the copyright information to show up in the PDF and to get a -nicer <variablelist> typesetting, but that is just a minor -technical detail.

- -

There were a few challenges, of course. We want to typeset the -short story to look like the original, and that require fairly good -control over the layout. The original short story have three -parts/scenes separated by a single horizontally centred star (*), and -the paragraphs do not contain only flowing text, but dialogs and text -that started on a new line in the middle of the paragraph.

- -

I initially solved the first challenge by using a paragraph with a -single star in it, ie <para>*</para>, but it made sure a -placeholder indicated where the scene shifted. This did not look too -good without the centring. The next approach was to create a new -preprocessor directive <?newscene?>, mapping to "<hr/>" -for HTML and "<fo:block text-align="center"><fo:leader -leader-pattern="rule" rule-thickness="0.5pt"/></fo:block>" -for FO/PDF output (did not try to implement this in dblatex, as we had -switched at this time). The HTML XSL file looked like this:

- -

-<?xml version='1.0'?> 
-<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version='1.0'>
-  <xsl:template match="processing-instruction('newscene')">
-    <hr/>
-  </xsl:template>
-</xsl:stylesheet> 
-

- -

And the FO/PDF XSL file looked like this:

- -

-<?xml version='1.0'?> 
-<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version='1.0'>
-  <xsl:template match="processing-instruction('newscene')">
-    <fo:block text-align="center">
-      <fo:leader leader-pattern="rule" rule-thickness="0.5pt"/>
-    </fo:block>
-  </xsl:template>
-</xsl:stylesheet> 
-

- -

Finally, I came across the <bridgehead> tag, which seem to be -a good fit for the task at hand, and I replaced <?newscene?> -with <bridgehead>*</bridgehead>. It isn't centred, but we -can fix it with some XSL rule if the current visual layout isn't -enough.

- -

I did not find a good DocBook compliant way to solve the -linebreak/paragraph challenge, so I ended up creating a new processor -directive <?linebreak?>, mapping to <br/> in HTML, and -<fo:block/> in FO/PDF. I suspect there are better ways to do -this, and welcome ideas and patches on github. The HTML XSL file now -look like this:

- -

-<?xml version='1.0'?> 
-<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version='1.0'>
-  <xsl:template match="processing-instruction('linebreak)">
-    <br/>
-  </xsl:template>
-</xsl:stylesheet> 
-

- -

And the FO/PDF XSL file looked like this:

- -

-<?xml version='1.0'?> 
-<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version='1.0'
-  xmlns:fo="http://www.w3.org/1999/XSL/Format">
-  <xsl:template match="processing-instruction('linebreak)">
-    <fo:block/>
-  </xsl:template>
-</xsl:stylesheet> 
-

- -

One unsolved challenge is our wish to expose different ISBN numbers -per publication format, while keeping all of them in some conditional -structure in the DocBook source. No idea how to do this, so we ended -up listing all the ISBN numbers next to their format in the colophon -page.

- -

If you want to check out the finished result, check out the -source repository at -github -(future/new/official -repository). We expect it to be ready and announced in a few -days.
