Lawrence Lessig interviewed Edward Snowden a year ago
-
19th October 2015
-

Last year, US president candidate -in the Democratic Party Lawrence interviewed Edward Snowden. The -one hour interview was -published by -Harvard Law School 2014-10-23 on Youtube, and the meeting took -place 2014-10-20.

- -

The questions are very good, and there is lots of useful -information to be learned and very interesting issues to think about -being raised. Please check it out.

- - - -

I find it especially interesting to hear again that Snowden did try -to bring up his reservations through the official channels without any -luck. It is in sharp contrast to the answers made 2013-11-06 by the -Norwegian prime minister Erna Solberg to the Norwegian Parliament, -claiming -Snowden is no Whistle-Blower because he should have taken up his -concerns internally and using official channels. It make me sad -that this is the political leadership we have here in Norway.

The new "best" multimedia player in Debian?
+
6th June 2016
+

When I set out a few weeks ago to figure out +which +multimedia player in Debian claimed to support most file formats / +MIME types, I was a bit surprised how varied the sets of MIME types +the various players claimed support for. The range was from 55 to 130 +MIME types. I suspect most media formats are supported by all +players, but this is not really reflected in the MimeTypes values in +their desktop files. There are probably also some bogus MIME types +listed, but it is hard to identify which one this is.

+ +

Anyway, in the mean time I got in touch with upstream for some of +the players suggesting to add more MIME types to their desktop files, +and decided to spend some time myself improving the situation for my +favorite media player VLC. The fixes for VLC entered Debian unstable +yesterday. The complete list of MIME types can be seen on the +Multimedia +player MIME type support status Debian wiki page.

+ +

The new "best" multimedia player in Debian? It is VLC, followed by +totem, parole, kplayer, gnome-mpv, mpv, smplayer, mplayer-gui and +kmplayer. I am sure some of the other players desktop files support +several of the formats currently listed as working only with vlc, +toten and parole.

+ +

A sad observation is that only 14 MIME types are listed as +supported by all the tested multimedia players in Debian in their +desktop files: audio/mpeg, audio/vnd.rn-realaudio, audio/x-mpegurl, +audio/x-ms-wma, audio/x-scpls, audio/x-wav, video/mp4, video/mpeg, +video/quicktime, video/vnd.rn-realvideo, video/x-matroska, +video/x-ms-asf, video/x-ms-wmv and video/x-msvideo. Personally I find +it sad that video/ogg and video/webm is not supported by all the media +players in Debian. As far as I can tell, all of them can handle both +formats.

The Story of Aaron Swartz - Let us all weep!

8th October 2015

The movie "The -Internet's Own Boy: The Story of Aaron Swartz" is both inspiring -and depressing at the same time. The work of Aaron Swartz has -inspired me in my work, and I am grateful of all the improvements he -was able to initiate or complete. I wish I am able to do as much good -in my life as he did in his. Every minute of this 1:45 long movie is -inspiring in documenting how much impact a single person can have on -improving the society and this world. And it is depressing in -documenting how the law enforcement of USA (and other countries) is -corrupted to a point where they can push a bright kid to his death for -downloading too many scientific articles. Aaron is dead. Let us all -weep.

The movie is also available on -Youtube. I -wish there were Norwegian subtitles available, so I could show it to -my parents.

A program should be able to open its own files on Linux
+
5th June 2016
+

Many years ago, when koffice was fresh and with few users, I +decided to test its presentation tool when making the slides for a +talk I was giving for NUUG on Japhar, a free Java virtual machine. I +wrote the first draft of the slides, saved the result and went to bed +the day before I would give the talk. The next day I took a plane to +the location where the meeting should take place, and on the plane I +started up koffice again to polish the talk a bit, only to discover +that kpresenter refused to load its own data file. I cursed a bit and +started making the slides again from memory, to have something to +present when I arrived. I tested that the saved files could be +loaded, and the day seemed to be rescued. I continued to polish the +slides until I suddenly discovered that the saved file could no longer +be loaded into kpresenter. In the end I had to rewrite the slides +three times, condensing the content until the talk became shorter and +shorter. After the talk I was able to pinpoint the problem – +kpresenter wrote inline images in a way itself could not understand. +Eventually that bug was fixed and kpresenter ended up being a great +program to make slides. The point I'm trying to make is that we +expect a program to be able to load its own data files, and it is +embarrassing to its developers if it can't.

+ +

Did you ever experience a program failing to load its own data +files from the desktop file browser? It is not a uncommon problem. A +while back I discovered that the screencast recorder +gtk-recordmydesktop would save an Ogg Theora video file the KDE file +browser would refuse to open. No video player claimed to understand +such file. I tracked down the cause being file --mime-type +returning the application/ogg MIME type, which no video player I had +installed listed as a MIME type they would understand. I asked for +file to change its +behavour and use the MIME type video/ogg instead. I also asked +several video players to add video/ogg to their desktop files, to give +the file browser an idea what to do about Ogg Theora files. After a +while, the desktop file browsers in Debian started to handle the +output from gtk-recordmydesktop properly.

+ +

But history repeats itself. A few days ago I tested the music +system Rosegarden again, and I discovered that the KDE and xfce file +browsers did not know what to do with the Rosegarden project files +(*.rg). I've reported the +rosegarden problem to BTS and a fix is commited to git and will be +included in the next upload. To increase the chance of me remembering +how to fix the problem next time some program fail to load its files +from the file browser, here are some notes on how to fix it.

+ +

The file browsers in Debian in general operates on MIME types. +There are two sources for the MIME type of a given file. The output from +file --mime-type mentioned above, and the content of the +shared MIME type registry (under /usr/share/mime/). The file MIME +type is mapped to programs supporting the MIME type, and this +information is collected from +the +desktop files available in /usr/share/applications/. If there is +one desktop file claiming support for the MIME type of the file, it is +activated when asking to open a given file. If there are more, one +can normally select which one to use by right-clicking on the file and +selecting the wanted one using 'Open with' or similar. In general +this work well. But it depend on each program picking a good MIME +type (preferably +a +MIME type registered with IANA), file and/or the shared MIME +registry recognizing the file and the desktop file to list the MIME +type in its list of supported MIME types.

+ +

The /usr/share/mime/packages/rosegarden.xml entry for +the +Shared MIME database look like this:

+ +

+<?xml version="1.0" encoding="UTF-8"?>
+<mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info">
+  <mime-type type="audio/x-rosegarden">
+    <sub-class-of type="application/x-gzip"/>
+    <comment>Rosegarden project file</comment>
+    <glob pattern="*.rg"/>
+  </mime-type>
+</mime-info>
+

+ +

This states that audio/x-rosegarden is a kind of application/x-gzip +(it is a gzipped XML file). Note, it is much better to use an +official MIME type registered with IANA than it is to make up ones own +unofficial ones like the x-rosegarden type used by rosegarden.

+ +

The desktop file of the rosegarden program failed to list +audio/x-rosegarden in its list of supported MIME types, causing the +file browsers to have no idea what to do with *.rg files:

+ +

+% grep Mime /usr/share/applications/rosegarden.desktop
+MimeType=audio/x-rosegarden-composition;audio/x-rosegarden-device;audio/x-rosegarden-project;audio/x-rosegarden-template;audio/midi;
+X-KDE-NativeMimeType=audio/x-rosegarden-composition
+%
+

+ +

The fix was to add "audio/x-rosegarden;" at the end of the +MimeType= line.

+ +

If you run into a file which fail to open the correct program when +selected from the file browser, please check out the output from +file --mime-type for the file, ensure the file ending and +MIME type is registered somewhere under /usr/share/mime/ and check +that some desktop file under /usr/share/applications/ is claiming +support for this MIME type. If not, please report a bug to have it +fixed. :)

Alle Stortingets mobiltelefoner kontrolleres fra USA...
-
7th October 2015

Jeg lot meg fascinere av -en -artikkel i Aftenposten der det fortelles at «over 600 telefoner som -benyttes av stortingsrepresentanter, rådgivere og ansatte på -Stortinget, kan «fjernstyres» ved hjelp av -programvaren -Airwatch, et såkalte MDM-program (Mobile Device Managment)». Det -hele bagatelliseres av Stortingets IT-stab, men det er i hovedsak på -grunn av at journalisten ikke stiller de relevante spørsmålene. For -meg er det relevante spørsmålet hvem som har lovlig tilgang (i henhold -til lokal lovgiving, dvs. i hvert fall i Norge, Sverige, UK og USA) -til informasjon om og på telefonene, og hvor enkelt det er å skaffe -seg tilgang til hvor mobilene befinner seg og informasjon som befinner -seg på telefonene ved hjelp av utro tjenere, trusler, innbrudd og -andre ulovlige metoder.

- -

Bruken av AirWatch betyr i realiteten at USAs etteretning og -politimyndigheter har full tilgang til stortingets mobiltelefoner, -inkludert posisjon og innhold, takket være -FISAAA-loven -og -"National -Security Letters" og det enkle faktum at selskapet -AirWatch er kontrollert av et -selskap i USA. I tillegg er det kjent at flere lands -etterretningstjenester kan lytte på trafikken når den passerer -landegrensene.

- -

Jeg har bedt om mer informasjon -fra -Stortinget om bruken av AirWatch via Mimes brønn så får vi se hva -de har å fortelle om saken. Fant ingenting om 'airwatch' i -postjournalen til Stortinget, så jeg trenger hjelp før jeg kan be om -innsyn i konkrete dokumenter.

Oppdatering 2015-10-07: Jeg er blitt spurt hvorfor jeg antar at -AirWatch-agenten rapporterer til USA og ikke direkte til Stortingets -egen infrastruktur. Det stemmer at det er teknisk mulig å sette -opp mobiltelefonene til å rapportere til datamaskiner som eies av -Stortinget. Jeg antar det rapporteres til AirWatch sine sentrale -tjenester basert på det jeg leste fra beskrivelsen av -Mobile -Device Management på AirWatch sine egne nettsider, koblet med at -det brukes en standard app som kan hentes fra "app-butikkene" for å få -tilgang. Enten må app-en settes opp individuelt hos Stortinget, eller -så får den beskjed fra AirWatch i USA om hvor den skal koble seg opp. -I det første tilfellet vil den ikke rapportere direkte til USA, men -til programvare utviklet av AirWatch som kjører på en maskin under -Stortingets kontroll. Det er litt bedre, men fortsatt vil det være -umulig for Stortinget å være sikker på hva programvaren som tar imot -forbindelser gjør. Jeg ser fra beskrivelsen av -Enterprice -Integration hos AirWatch at det er mulig å ha lokal installasjon, -og håper innsynsforespørsler mot Stortinget kan fortelle mer om -hvordan ting konkret fungerer der.

Tor - from its creators mouth 11 years ago

Isenkram with PackageKit support - new version 0.23 available in Debian unstable
+
25th May 2016
+

The isenkram +system is a user-focused solution in Debian for handling hardware +related packages. The idea is to have a database of mappings between +hardware and packages, and pop up a dialog suggesting for the user to +install the packages to use a given hardware dongle. Some use cases +are when you insert a Yubikey, it proposes to install the software +needed to control it; when you insert a braille reader list it +proposes to install the packages needed to send text to the reader; +and when you insert a ColorHug screen calibrator it suggests to +install the driver for it. The system work well, and even have a few +command line tools to install firmware packages and packages for the +hardware already in the machine (as opposed to hotpluggable hardware).

+ +

The system was initially written using aptdaemon, because I found +good documentation and example code on how to use it. But aptdaemon +is going away and is generally being replaced by +PackageKit, +so Isenkram needed a rewrite. And today, thanks to the great patch +from my college Sunil Mohan Adapa in the FreedomBox project, the +rewrite finally took place. I've just uploaded a new version of +Isenkram into Debian Unstable with the patch included, and the default +for the background daemon is now to use PackageKit. To check it out, +install the isenkram package and insert some hardware dongle +and see if it is recognised.

+ +

If you want to know what kind of packages isenkram would propose for +the machine it is running on, you can check out the isenkram-lookup +program. This is what it look like on a Thinkpad X230:

+ +

+% isenkram-lookup

+pidgin-blinklight
+thinkfan
+tleds
+tp-smapi-dkms
+tp-smapi-source
+tpb
+%p
+

+ +

The hardware mappings come from several places. The preferred way +is for packages to announce their hardware support using +the +cross distribution appstream system. +See +previous +blog posts about isenkram to learn how to do that.

The life and death of a laptop battery
-
24th September 2015
-

When I get a new laptop, the battery life time at the start is OK. -But this do not last. The last few laptops gave me a feeling that -within a year, the life time is just a fraction of what it used to be, -and it slowly become painful to use the laptop without power connected -all the time. Because of this, when I got a new Thinkpad X230 laptop -about two years ago, I decided to monitor its battery state to have -more hard facts when the battery started to fail.

- - - -

First I tried to find a sensible Debian package to record the -battery status, assuming that this must be a problem already handled -by someone else. I found -battery-stats, -which collects statistics from the battery, but it was completely -broken. I sent a few suggestions to the maintainer, but decided to -write my own collector as a shell script while I waited for feedback -from him. Via -a -blog post about the battery development on a MacBook Air I also -discovered -batlog, not -available in Debian.

- -

I started my collector 2013-07-15, and it has been collecting -battery stats ever since. Now my -/var/log/hjemmenett-battery-status.log file contain around 115,000 -measurements, from the time the battery was working great until now, -when it is unable to charge above 7% of original capacity. My -collector shell script is quite simple and look like this:

- -
-#!/bin/sh
-# Inspired by
-# http://www.ifweassume.com/2013/08/the-de-evolution-of-my-laptop-battery.html
-# See also

-    energy_full energy_full_design energy_now cycle_count status"

-    (
-	printf "timestamp,"
-	for f in $files; do
-	    printf "%s," $f
-	done
-	echo
-    ) > "$logfile"
-fi
-
-log_battery() {
-    # Print complete message in one echo call, to avoid race condition
-    # when several log processes run in parallel.
-    msg=$(printf "%s," $(date +%s); \
-	for f in $files; do \
-	    printf "%s," $(cat $f); \
-	done)
-    echo "$msg"
-}
-
-cd /sys/class/power_supply
-
-for bat in BAT*; do
-    (cd $bat && log_battery >> "$logfile")
-done
-
- -

The script is called when the power management system detect a -change in the power status (power plug in or out), and when going into -and out of hibernation and suspend. In addition, it collect a value -every 10 minutes. This make it possible for me know when the battery -is discharging, charging and how the maximum charge change over time. -The code for the Debian package -is now -available on github.

- -

The collected log file look like this:

- -
-timestamp,manufacturer,model_name,technology,serial_number,energy_full,energy_full_design,energy_now,cycle_count,status,
-1376591133,LGC,45N1025,Li-ion,974,62800000,62160000,39050000,0,Discharging,

-
- -

I wrote a small script to create a graph of the charge development -over time. This graph depicted above show the slow death of my laptop -battery.

- -

But why is this happening? Why are my laptop batteries always -dying in a year or two, while the batteries of space probes and -satellites keep working year after year. If we are to believe -Battery -University, the cause is me charging the battery whenever I have a -chance, and the fix is to not charge the Lithium-ion batteries to 100% -all the time, but to stay below 90% of full charge most of the time. -I've been told that the Tesla electric cars -limit -the charge of their batteries to 80%, with the option to charge to -100% when preparing for a longer trip (not that I would want a car -like Tesla where rights to privacy is abandoned, but that is another -story), which I guess is the option we should have for laptops on -Linux too.

- -

Is there a good and generic way with Linux to tell the battery to -stop charging at 80%, unless requested to charge to 100% once in -preparation for a longer trip? I found -one -recipe on askubuntu for Ubuntu to limit charging on Thinkpad to -80%, but could not get it to work (kernel module refused to -load).

- -

I wonder why the battery capacity was reported to be more than 100% -at the start. I also wonder why the "full capacity" increases some -times, and if it is possible to repeat the process to get the battery -back to design capacity. And I wonder if the discharge and charge -speed change over time, or if this stay the same. I did not yet try -to write a tool to calculate the derivative values of the battery -level, but suspect some interesting insights might be learned from -those.

- -

Update 2015-09-24: I got a tip to install the packages -acpi-call-dkms and tlp (unfortunately missing in Debian stable) -packages instead of the tp-smapi-dkms package I had tried to use -initially, and use 'tlp setcharge 40 80' to change when charging start -and stop. I've done so now, but expect my existing battery is toast -and need to be replaced. The proposal is unfortunately Thinkpad -specific.

Discharge rate estimate in new battery statistics collector for Debian
+
23rd May 2016
+

Yesterday I updated the +battery-stats +package in Debian with a few patches sent to me by skilled and +enterprising users. There were some nice user and visible changes. +First of all, both desktop menu entries now work. A design flaw in +one of the script made the history graph fail to show up (its PNG was +dumped in ~/.xsession-errors) if no controlling TTY was available. +The script worked when called from the command line, but not when +called from the desktop menu. I changed this to look for a DISPLAY +variable or a TTY before deciding where to draw the graph, and now the +graph window pop up as expected.

+ +

The next new feature is a discharge rate estimator in one of the +graphs (the one showing the last few hours). New is also the user of +colours showing charging in blue and discharge in red. The percentages +of this graph is relative to last full charge, not battery design +capacity.

+ +

+ +

The other graph show the entire history of the collected battery +statistics, comparing it to the design capacity of the battery to +visualise how the battery life time get shorter over time. The red +line in this graph is what the previous graph considers 100 percent: + +

+ +

In this graph you can see that I only charge the battery to 80 +percent of last full capacity, and how the capacity of the battery is +shrinking. :(

+ +

The last new feature is in the collector, which now will handle +more hardware models. On some hardware, Linux power supply +information is stored in /sys/class/power_supply/ACAD/, while the +collector previously only looked in /sys/class/power_supply/AC/. Now +both are checked to figure if there is power connected to the +machine.

+ +

If you are interested in how your laptop battery is doing, please +check out the +battery-stats +in Debian unstable, or rebuild it on Jessie to get it working on +Debian stable. :) The upstream source is available from github. +Patches are very welcome.

Book cover for the Free Culture book finally done

Today, finally, my first printed draft edition of the Norwegian -translation of Free Culture I have been working on for the last few -years arrived in the mail.

I want the courts to be involved before the police can hijack a news site DNS domain (#domstolkontroll)
+
19th May 2016
+

I just donated to the +NUUG defence +"fond" to fund the effort in Norway to get the seizure of the news +site popcorn-time.no tested in court. I hope everyone that agree with +me will do the same.

+ +

Would you be worried if you knew the police in your country could +hijack DNS domains of news sites covering free software system without +talking to a judge first? I am. What if the free software system +combined search engine lookups, bittorrent downloads and video playout +and was called Popcorn Time? Would that affect your view? It still +make me worried.

+ +

In March 2016, the Norwegian police seized (as in forced NORID to +change the IP address pointed to by it to one controlled by the +police) the DNS domain popcorn-time.no, without any supervision from +the courts. I did not know about the web site back then, and assumed +the courts had been involved, and was very surprised when I discovered +that the police had hijacked the DNS domain without asking a judge for +permission first. I was even more surprised when I had a look at +the web +site content on the Internet Archive, and only found news coverage +about Popcorn Time, not any material published without the right +holders permissions.

+ +

The seizure was widely covered in the Norwegian press (see for +example Hegnar Online and +ITavisen +and +NRK), +at first due to the press release sent out by Økokrim, but then based +on +protests +from the law professor Olav Torvund and +lawyer +Jon Wessel-Aas. It even got some +coverage +on TorrentFreak.

+ +

I + +wrote about the case a month ago, when the +Norwegian Unix User Group (NUUG), +where I am an active member, decided to ask the courts to test this seizure. +The request was denied, but NUUG and its co-requestor EFN have not +given up, and now they are rallying for support to get the seizure +legally challenged. They accept both bank and Bitcoin transfer for +those that want to support the request.

+ +

If you as me believe news sites about free software should not be +censored, even if the free software have both legal and illegal +applications, and that DNS hijacking should be tested by the courts, I +suggest you show +your support by donating to NUUG.

First paper version of the Norwegian Free Culture book heading my way
-
9th August 2015
-

Typesetting a book is harder than I hoped. As the translation is -mostly done, and a volunteer proof reader was going to check the text -on paper, it was time this summer to focus on formatting my translated -docbook based version of the -Free Culture book by Lawrence -Lessig. I've been trying to get both docboox-xsl+fop and dblatex to -give me a good looking PDF, but in the end I went with dblatex, because -its Debian maintainer and upstream developer were responsive and very -helpful in solving my formatting challenges.

- -

Last night, I finally managed to create a PDF that no longer made -Lulu.com complain after uploading, -and I ordered a text version of the book on paper. It is lacking a -proper book cover and is not tagged with the correct ISBN number, but -should give me an idea what the finished book will look like.

- -

Instead of using Lulu, I did consider printing the book using -CreateSpace, but ended up -using Lulu because it had smaller book size options (CreateSpace seem -to lack pocket book with extended distribution). I looked for a -similar service in Norway, but have not seen anything so far. Please -let me know if I am missing out on something here.

- -

But I still struggle to decide the book size. Should I go for -pocket book (4.25x6.875 inches / 10.8x17.5 cm) with 556 pages, Digest -(5.5x8.5 inches / 14x21.6 cm) with 323 pages or US Trade (6x8 inches / -15.3x22.9 cm) with 280 pages? Fewer pager give a cheaper book, and a -smaller book is easier to carry around. The test book I ordered was -pocket book sized, to give me an idea how well that fit in my hand, -but I suspect I will end up using a digest sized book in the end to -bring the prize down further.

- -

My biggest challenge at the moment is making nice cover art. My -inkscape skills are not yet up to the task of replicating the original -cover in SVG format. I also need to figure out what to write about -the book on the back (will most likely use the same text as the -description on web based book stores). I would love help with this, -if you are willing to license the art source and final version using -the same CC license as the book. My artistic skills are not really up -to the task.

- -

I plan to publish the book in both English and Norwegian and on -paper, in PDF form as well as EPUB and MOBI format. The current -status can as usual be found on -github -in the archive/ directory. So far I have spent all time on making the -PDF version look good. Someone should probably do the same with the -dbtoepub generated e-book. Help is definitely needed here, as I -expect to run out of steem before I find time to improve the epub -formatting.

- -

Please let me know via github if you find typos in the book or -discover translations that should be improved. The final proof -reading is being done right now, and I expect to publish the finished -result in a few months.

Typesetting DocBook footnotes as endnotes with dblatex
-
16th July 2015
-

I'm still working on the Norwegian version of the -Free Culture book by Lawrence -Lessig, and is now working on the final typesetting and layout. -One of the features I want to get the structure similar to the -original book is to typeset the footnotes as endnotes in the notes -chapter. Based on the -feedback from the Debian -maintainer and the dblatex developer, I came up with this recipe I -would like to share with you. The proposal was to create a new LaTeX -class file and add the LaTeX code there, but this is not always -practical, when I want to be able to replace the class using a make -file variable. So my proposal misuses the latex.begindocument XSL -parameter value, to get a small fragment into the correct location in -the generated LaTeX File.

- -

First, decide where in the DocBook document to place the endnotes, -and add this text there:

- -
-<?latex \theendnotes ?>
-
- -

Next, create a xsl stylesheet file dblatex-endnotes.xsl to add the -code needed to add the endnote instructions in the preamble of the -generated LaTeX document, with content like this:

- -
-<?xml version='1.0'?>
-<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version='1.0'>
-  <xsl:param name="latex.begindocument">
-    <xsl:text>
-\usepackage{endnotes}
-\let\footnote=\endnote
-\def\enoteheading{\mbox{}\par\vskip-\baselineskip }
-\begin{document}
-    </xsl:text>
-  </xsl:param>
-</xsl:stylesheet>
-
- -

Finally, load this xsl file when running dblatex, for example like -this:

- -
-dblatex --xsl-user=dblatex-endnotes.xsl freeculture.nb.xml

The end result can be seen on github, where -my -book project is located.

What is the best multimedia player in Debian?
+
8th May 2016
+

Where I set out to figure out which multimedia player in +Debian claim support for most file formats.

+ +

A few years ago, I had a look at the media support for Browser +plugins in Debian, to get an idea which plugins to include in Debian +Edu. I created a script to extract the set of supported MIME types +for each plugin, and used this to find out which multimedia browser +plugin supported most file formats / media types. +The +result can still be seen on the Debian wiki, even though it have +not been updated for a while. But browser plugins are less relevant +these days, so I thought it was time to look at standalone +players.

+ +

A few days ago I was tired of VLC not being listed as a viable +player when I wanted to play videos from the Norwegian National +Broadcasting Company, and decided to investigate why. The cause is a +missing MIME type in the VLC +desktop file. In the process I wrote a script to compare the set +of MIME types announced in the desktop file and the browser plugin, +only to discover that there is quite a large difference between the +two for VLC. This discovery made me dig up the script I used to +compare browser plugins, and adjust it to compare desktop files +instead, to try to figure out which multimedia player in Debian +support most file formats.

+ +

The result can be seen on the Debian Wiki, as +a +table listing all MIME types supported by one of the packages included +in the table, with the package supporting most MIME types being +listed first in the table.

+ +

The best multimedia player in Debian? It is totem, followed by +parole, kplayer, mpv, vlc, smplayer mplayer-gui gnome-mpv and +kmplayer. Time for the other players to update their announced MIME +support?

Mimes brønn, norsk utgave av Alaveteli / WhatDoTheyKnow, endelig lansert
-
9th July 2015
-

I går fikk vi endelig lansert en norsk version av mySocietys -WhatDoTheyKnow. -Tjenesten heter Mimes brønn, og ble -annonsert -av NUUG via blogg, epost og twitter til NUUG-assosierte personer. -Det har tatt noen år, men de siste dagene fikk vi endelig tid til å få -på plass de siste bitene. Vi er to, Gorm og meg selv, som har vært -primus motor for det hele, men vi har fått hjelp med oversettelser og -oppsett fra mange flere. Jeg vil si tusen takk til hver og en av dem, -og er veldig fornøyd med at vi klarte å få tjenesten opp å kjøre før -ferietiden slo inn for fullt.

- -

Vi er usikker på hvor mye belastning den virtuelle maskinen der -tjenesten kjører klarer, så vi har lansert litt i det stille og ikke -til for mange folk for å se hvordan maskinen klarer seg over sommeren, -før vi går mer aktivt ut og annonserer til høsten. Ta en titt, og se -om du kanskje har et spørsmål til det offentlige som er egnet å sende -inn via Mimes brønn.

- -

Hvis du lurer på hva i alle dager en slik tjenestes kan brukes til, -anbefaler jeg deg å se -TED-foredraget til -Heather Brook om hvordan hun brukte WhatDoTheyKnow til å lære -hvordan offentlige midler ble misbrukt. Det er en inspirerende -historie.

The Pyra - handheld computer with Debian preinstalled
+
4th May 2016
+
A friend of mine made me aware of +The Pyra, a +handheld computer which will be delivered with Debian preinstalled. I +would love to get one of those for my birthday. :)

+ +

The machine is a complete ARM-based PC with micro HDMI, SATA, USB +plugs and many others connectors, and include a full keyboard and a 5" +LCD touch screen. The 6000mAh battery is claimed to provide a whole +day of battery life time, but I have not seen any independent tests +confirming this. The vendor is still collecting preorders, and the +last I heard last night was that 22 more orders were needed before +production started.

+ +

As far as I know, this is the first handheld preinstalled with +Debian. Please let me know if you know of any others. Is it the +first computer being sold with Debian preinstalled?
