- <description><p>Yesterday, I wrote about the
-<a href="http://people.skolelinux.org/pere/blog/Modalias_strings___a_practical_way_to_map__stuff__to_hardware.html">modalias
-values provided by the Linux kernel</a> following my hope for
-<a href="http://people.skolelinux.org/pere/blog/Lets_make_hardware_dongles_easier_to_use_in_Debian.html">better
-dongle support in Debian</a>. Using this knowledge, I have tested how
-modalias values attached to package names can be used to map packages
-to hardware. This allow the system to look up and suggest relevant
-packages when I plug in some new hardware into my machine, and replace
-discover and discover-data as the database used to map hardware to
-packages.</p>
-
-<p>I create a modaliases file with entries like the following,
-containing package name, kernel module name (if relevant, otherwise
-the package name) and globs matching the relevant hardware
-modalias.</p>
-
-<p><blockquote>
-Package: package-name
-<br>Modaliases: module(modaliasglob, modaliasglob, modaliasglob)</p>
-</blockquote></p>
-
-<p>It is fairly trivial to write code to find the relevant packages
-for a given modalias value using this file.</p>
-
-<p>An entry like this would suggest the video and picture application
-cheese for many USB web cameras (interface bus class 0E01):</p>
-
-<p><blockquote>
-Package: cheese
-<br>Modaliases: cheese(usb:v*p*d*dc*dsc*dp*ic0Eisc01ip*)</p>
-</blockquote></p>
-
-<p>An entry like this would suggest the pcmciautils package when a
-CardBus bridge (bus class 0607) PCI device is present:</p>
-
-<p><blockquote>
-Package: pcmciautils
-<br>Modaliases: pcmciautils(pci:v*d*sv*sd*bc06sc07i*)
-</blockquote></p>
-
-<p>An entry like this would suggest the package colorhug-client when
-plugging in a ColorHug with USB IDs 04D8:F8DA:</p>
-
-<p><blockquote>
-Package: colorhug-client
-<br>Modaliases: colorhug-client(usb:v04D8pF8DAd*)</p>
-</blockquote></p>
-
-<p>I believe the format is compatible with the format of the Packages
-file in the Debian archive. Ubuntu already uses their Packages file
-to store their mappings from packages to hardware.</p>
-
-<p>By adding a XB-Modaliases: header in debian/control, any .deb can
-announce the hardware it support in a way my prototype understand.
-This allow those publishing packages in an APT source outside the
-Debian archive as well as those backporting packages to make sure the
-hardware mapping are included in the package meta information. I've
-tested such header in the pymissile package, and its modalias mapping
-is working as it should with my prototype. It even made it to Ubuntu
-Raring.</p>
-
-<p>To test if it was possible to look up supported hardware using only
-the shell tools available in the Debian installer, I wrote a shell
-implementation of the lookup code. The idea is to create files for
-each modalias and let the shell do the matching. Please check out and
-try the
-<a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/hw-support-lookup?view=co">hw-support-lookup</a>
-shell script. It run without any extra dependencies and fetch the
-hardware mappings from the Debian archive and the subversion
-repository where I currently work on my prototype.</p>
-
-<p>When I use it on a machine with a yubikey inserted, it suggest to
-install yubikey-personalization:</p>
-
-<p><blockquote>
-% ./hw-support-lookup
-<br>yubikey-personalization:
-<br>%
-</blockquote></p>
-
-<p>When I run it on my Thinkpad X40 with a PCMCIA/CardBus slot, it
-propose to install the pcmciautils package:</p>
-
-<p><blockquote>
-% ./hw-support-lookup
-<br>pcmciautils
-<br>%
-</blockquote></p>
-
-<p>If you know of any hardware-package mapping that should be added to
-<a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/modaliases?view=co">my
-database</a>, please tell me about it.</p>
-
-<p>It could be possible to generate several of the mappings between
-packages and hardware. One source would be to look at packages with
-kernel modules, ie packages with *.ko files in /lib/modules/, and
-extract their modalias information. Another would be to look at
-packages with udev rules, ie packages with files in
-/lib/udev/rules.d/, and extract their vendor/model information to
-generate a modalias matching rule. I have not tested any of these to
-see if it work.</p>
-
-<p>If you want to help implementing a system to let us propose what
-packages to install when new hardware is plugged into a Debian
-machine, please send me an email or talk to me on

+ <description><p>Do you want to set up your own TV station, schedule videos and
+broadcast them on the air? Using free software? With video on demand
+support using
+<a href="http://www.digistan.org/open-standard:definition">free and
+open standards</a>? Included a web based video stream as well? And
+administrate it all in your web browser from anywhere in the world? A
+few years now the Norwegian public access TV-channel
+<a href="http://www.frikanalen.no/">Frikanalen</a> have been building a
+system to do just this. The source code for the solution is licensed
+using the GNU LGPL, and
+<a href="http://github.com/Frikanalen">available from github</a>.</p>
+
+<p>The idea is simple. You upload a video file over the web, and
+attach meta information to the file. You select a time slot in the
+program schedule, and when the time come it is played on the air and
+in the web stream. It is also made available in a video on demand
+solution for anyone to see it also outside its scheduled time. All
+you need to run a TV station - using your web browser.</p>
+
+<p>There are several parts to this web based solution. I'll mention
+the three most important ones. The first part is the database of
+videos and the schedule. This is written in Django and include a REST
+API. The current database is SQLite, but the plan is to migrate it to
+PostgreSQL. At the moment this system can be tested on
+<a href="http://beta.frikanalen.tv/">beta.frikanalen.tv</a>. The
+second part is the video playout, taking the schedule information from
+the database and providing a video stream to broadcast. This is done
+using <a href="http://www.casparcg.com/">CasparCG from SVT</a> and
+<a href="http://www.mltframework.org/">Media Lovin' Toolkit</a>. Video
+signal distribution is handled using
+<a href="http://www.ob-encoder.com/">Open Broadcast Encoder</a>. The
+third part is the converter, handling the transformation of uploaded
+video files to a format useful for broadcasting, streaming and video
+on demand. It is still very much work in progress, so it is not yet
+decided what it will end up using. Note that the source of the latter
+two parts are not yet pushed to github. The lead author want to clean
+them up a bit more first.</p>
+
+<p>The development is coordinated on the
+<a href="irc://irc.freenode.net/%23frikanalen">#frikanalen IRC
+channel</a> (irc.freenode.net), and discussed on
+<a href="http://lists.nuug.no/mailman/listinfo/frikanalen">the
+frikanalen mailing list</a>. The lead developer is Benjamin Bruheim
+(phed on IRC). Anyone is welcome to participate in the
+development.</p>

- <description><p>While looking into how to look up Debian packages based on hardware
-information, to find the packages that support a given piece of
-hardware, I refreshed my memory regarding modalias values, and decided
-to document the details. Here are my findings so far, also available
-in
-<a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/">the
-Debian Edu subversion repository</a>:
-
-<p><strong>Modalias decoded</strong></p>
-
-<p>This document try to explain what the different types of modalias
-values stands for. It is in part based on information from
-&lt;URL: <a href="https://wiki.archlinux.org/index.php/Modalias">https://wiki.archlinux.org/index.php/Modalias</a> &gt;,
-&lt;URL: <a href="http://unix.stackexchange.com/questions/26132/how-to-assign-usb-driver-to-device">http://unix.stackexchange.com/questions/26132/how-to-assign-usb-driver-to-device</a> &gt;,

-
-<p>The modalias entries for a given Linux machine can be found using
-this shell script:</p>
-
-<pre>
-cat $(find /sys -name modalias) | sort -u
-</pre>
-
-<p>The supported modalias globs for a given kernel module can be found
-using modinfo:</p>
-
-<pre>
-% /sbin/modinfo psmouse | grep alias:
-alias: serio:ty05pr*id*ex*
-alias: serio:ty01pr*id*ex*
-%
-</pre>
-
-<p><strong>PCI subtype</strong></p>
-
-<p>A typical PCI entry can look like this. This is an Intel Host
-Bridge memory controller:</p>
-
-<p><blockquote>
-pci:v00008086d00002770sv00001028sd000001ADbc06sc00i00
-</blockquote></p>
-
-<p>This represent these values:</p>
-
-<pre>
- v 00008086 (vendor)
- d 00002770 (device)
- sv 00001028 (subvendor)
- sd 000001AD (subdevice)
- bc 06 (bus class)
- sc 00 (bus subclass)
- i 00 (interface)
-</pre>
-
-<p>The vendor/device values are the same values outputted from 'lspci
--n' as 8086:2770. The bus class/subclass is also shown by lspci as
-0600. The 0600 class is a host bridge. Other useful bus values are
-0300 (VGA compatible card) and 0200 (Ethernet controller).</p>
-
-<p>Not sure how to figure out the interface value, nor what it
-means.</p>
-
-<p><strong>USB subtype</strong></p>
-
-<p>Some typical USB entries can look like this. This is an internal
-USB hub in a laptop:</p>

+ <description><p>Dr. <a href="http://www.stallman.org/">Richard Stallman</a>,
+founder of <a href="http://www.fsf.org/">Free Software Foundation</a>,
+is giving <a href="http://www.nuug.no/aktiviteter/20130301-rms/">a
+talk in Oslo March 1st 2013 17:00 to 19:00</a>. The event is public
+and organised by <a href="">Norwegian Unix Users Group (NUUG)</a>
+(where I am the chair of the board) and
+<a href="http://www.friprog.no/">The Norwegian Open Source Competence
+Center</a>. The title of the talk is «The Free Software Movement and
+GNU», with this description:
<p><blockquote>
-usb:v1D6Bp0001d0206dc09dsc00dp00ic09isc00ip00
+The Free Software Movement campaigns for computer users' freedom to
+cooperate and control their own computing. The Free Software Movement
+developed the GNU operating system, typically used together with the
+kernel Linux, specifically to make these freedoms possible.
</blockquote></p>
-<p>Here is the values included in this alias:</p>
-
-<pre>
- v 1D6B (device vendor)
- p 0001 (device product)
- d 0206 (bcddevice)
- dc 09 (device class)
- dsc 00 (device subclass)
- dp 00 (device protocol)
- ic 09 (interface class)
- isc 00 (interface subclass)
- ip 00 (interface protocol)
-</pre>
-
-<p>The 0900 device class/subclass means hub. Some times the relevant
-class is in the interface class section. For a simple USB web camera,
-these alias entries show up:</p>
-
-<p><blockquote>
-usb:v0AC8p3420d5000dcEFdsc02dp01ic01isc01ip00
-<br>usb:v0AC8p3420d5000dcEFdsc02dp01ic01isc02ip00
-<br>usb:v0AC8p3420d5000dcEFdsc02dp01ic0Eisc01ip00
-<br>usb:v0AC8p3420d5000dcEFdsc02dp01ic0Eisc02ip00
-</blockquote></p>
-
-<p>Interface class 0E01 is video control, 0E02 is video streaming (aka
-camera), 0101 is audio control device and 0102 is audio streaming (aka
-microphone). Thus this is a camera with microphone included.</p>
-
-<p><strong>ACPI subtype</strong></p>
-
-<p>The ACPI type is used for several non-PCI/USB stuff. This is an IR
-receiver in a Thinkpad X40:</p>
-
-<p><blockquote>
-acpi:IBM0071:PNP0511:
-</blockquote></p>
-
-<p>The values between the colons are IDs.</p>
-
-<p><strong>DMI subtype</strong></p>
-
-<p>The DMI table contain lots of information about the computer case
-and model. This is an entry for a IBM Thinkpad X40, fetched from
-/sys/devices/virtual/dmi/id/modalias:</p>
-
-<p><blockquote>
-dmi:bvnIBM:bvr1UETB6WW(1.66):bd06/15/2005:svnIBM:pn2371H4G:pvrThinkPadX40:rvnIBM:rn2371H4G:rvrNotAvailable:cvnIBM:ct10:cvrNotAvailable:
-</blockquote></p>
-
-<p>The values present are</p>
-
-<pre>
- bvn IBM (BIOS vendor)
- bvr 1UETB6WW(1.66) (BIOS version)
- bd 06/15/2005 (BIOS date)
- svn IBM (system vendor)
- pn 2371H4G (product name)
- pvr ThinkPadX40 (product version)
- rvn IBM (board vendor)
- rn 2371H4G (board name)
- rvr NotAvailable (board version)
- cvn IBM (chassis vendor)
- ct 10 (chassis type)
- cvr NotAvailable (chassis version)
-</pre>
-
-<p>The chassis type 10 is Notebook. Other interesting values can be
-found in the dmidecode source:</p>
-
-<pre>
- 3 Desktop
- 4 Low Profile Desktop
- 5 Pizza Box
- 6 Mini Tower
- 7 Tower
- 8 Portable
- 9 Laptop
- 10 Notebook
- 11 Hand Held
- 12 Docking Station
- 13 All In One
- 14 Sub Notebook
- 15 Space-saving
- 16 Lunch Box
- 17 Main Server Chassis
- 18 Expansion Chassis
- 19 Sub Chassis
- 20 Bus Expansion Chassis
- 21 Peripheral Chassis
- 22 RAID Chassis
- 23 Rack Mount Chassis
- 24 Sealed-case PC
- 25 Multi-system
- 26 CompactPCI
- 27 AdvancedTCA
- 28 Blade
- 29 Blade Enclosing
-</pre>
-
-<p>The chassis type values are not always accurately set in the DMI
-table. For example my home server is a tower, but the DMI modalias
-claim it is a desktop.</p>
-
-<p><strong>SerIO subtype</strong></p>
-
-<p>This type is used for PS/2 mouse plugs. One example is from my
-test machine:</p>
-
-<p><blockquote>
-serio:ty01pr00id00ex00
-</blockquote></p>
-
-<p>The values present are</p>
-
-<pre>
- ty 01 (type)
- pr 00 (prototype)
- id 00 (id)
- ex 00 (extra)
-</pre>
-
-<p>This type is supported by the psmouse driver. I am not sure what
-the valid values are.</p>
-
-<p><strong>Other subtypes</strong></p>
-
-<p>There are heaps of other modalias subtypes according to
-file2alias.c. There is the rest of the list from that source: amba,
-ap, bcma, ccw, css, eisa, hid, i2c, ieee1394, input, ipack, isapnp,
-mdio, of, parisc, pcmcia, platform, scsi, sdio, spi, ssb, vio, virtio,
-vmbus, x86cpu and zorro. I did not spend time documenting all of
-these, as they do not seem relevant for my intended use with mapping
-hardware to packages when new stuff is inserted during run time.</p>
-
-<p><strong>Looking up kernel modules using modalias values</strong></p>
-
-<p>To check which kernel modules provide support for a given modalias,
-one can use the following shell script:</p>
-
-<pre>
- for id in $(cat $(find /sys -name modalias)|sort -u); do \
- echo "$id" ; \
- /sbin/modprobe --show-depends "$id"|sed 's/^/ /' ; \
- done
-</pre>
-
-<p>The output can look like this (only the first few entries as the
-list is very long on my test machine):</p>
-
-<pre>
- acpi:ACPI0003:
- insmod /lib/modules/2.6.32-5-686/kernel/drivers/acpi/ac.ko
- acpi:device:
- FATAL: Module acpi:device: not found.

- <description><p>As part of my investigation on how to improve the support in Debian
-for hardware dongles, I dug up my old Mark and Spencer USB Rocket
-Launcher and updated the Debian package
-<a href="http://packages.qa.debian.org/pymissile">pymissile</a> to make
-sure udev will fix the device permissions when it is plugged in. I
-also added a "Modaliases" header to test it in the Debian archive and
-hopefully make the package be proposed by jockey in Ubuntu when a user
-plug in his rocket launcher. In the process I moved the source to a
-git repository under collab-maint, to make it easier for any DD to
-contribute. <a href="http://code.google.com/p/pymissile/">Upstream</a>
-is not very active, but the software still work for me even after five
-years of relative silence. The new git repository is not listed in
-the uploaded package yet, because I want to test the other changes a
-bit more before I upload the new version. If you want to check out
-the new version with a .desktop file included, visit the

+ <description><p>Etter en lang pause og travle uker har jeg endelig klart å få
+samlet et nytt intervju med en av folkene i
+<a href="http://www.skolelinux.org/">Skolelinux</a>-miljøet.
+Denne gang er det Helge Tore Høyland, en mangeårig bidragsyter på
+epostlistene og ellers i prosjektet.</p>
+
+<p><strong>Hvem er du, og hva driver du med til daglig?</strong></p>
+
+<p>Eg er IT-konsulent/teknikker hjå eit firma i Steinkjer med navn
+<a href="http://unoit.no/">Uno IT</a>. Uno IT er eit lite firma som
+drifter nettverk og maskiner for små og mellomstore firma
+Steinkjer-området. Per dags dato er me 2 ansatte. Min faglege bakgrunn
+er Fagbrev som it-teknikker, samt nokre fag innen nettverk- og
+server-drift frå HiST og NTNU. Dagleg arbeid består i oppsett av nye
+maskiner og hjelp til sluttbrukere, samt oppsett og vedlikehold av eit
+vidt spekter av fagsystemer ute hjå kunder. Erfaring med Skolelinux
+har eg hatt i forbindelse med drifting av
+<a href="http://www.bjorkly.no/">Bjørkly skule</a>, ein privat
+grunnskule i Namsos-området. I dag har skulen 65 elever, 15 lærere, 1
+hovedserver og ca 60 klienter som kjører halvtjukt. Eg har bygd og
+driftet systemet sidan summaren 2006.</p>
+
+<p><strong>Hvordan kom du i kontakt med Skolelinux-prosjektet?</strong></p>
+
+<p>Eg kom i kontakt med Skolelinux-prosjektet via ein artikkel i eit
+fagblad, som eg ikkje lenger hugsar namnet på. I og med at eg allereie
+hadde pusla med nettverk for ein annan skule, fatta eg straks
+interesse for prosjektet.</p>
+
+<p><strong>Hva er fordelene med Skolelinux slik du ser det?</strong></p>
+
+<p>Fordelane med Skolelinux er sentralisert administrasjon og svært
+mange gode verktøy «ut av boksen». Veldig kjekt å kunne drifte 60
+klientar med berre å «bry» seg med ein server. Levetid for systemets
+hardware er og ein veldig fin effekt. I tillegg kjem fordelar som økt
+sikkerhet og mindre lisenskostnader. Etter min erfaring er det og
+mykje mindre driftskostnader med eit slikt system enn konkurrerande
+system, pga enkelhet med sentralisert administrasjon. På grunn av at
+Skolelinux er basert på Debian er det òg svært stabilt.</p>
+
+<p><strong>Hva er ulempene med Skolelinux slik du ser det?</strong></p>
+
+<p>Ulemper er mangel på vilje til å følge standarer ute i markedet,
+som fører til mangel på støtte til nokre mykje brukte ting. Flash og
+Java er typiske eksempel. Sidan Debian satsar på stabilitet framfor å
+ha nyeste pakke av eit program, kan ein i nokre tilfeller kome borti
+at program vert «for gamle». Det er spesielt nettlesaren som er
+utsett. Mangel på vilje til å utvikle pedagogisk programvare, i Noreg,
+for «alle» platformer fører òg til noko hovudbry.</p>
+
+<p><strong>Hvilken fri programvare bruker du til daglig?</strong></p>
+
+<p>Til dagleg bruker eg svært mange forskjellige «fri programvare»
+program. Firefox, Thunderbird, Freecommander, ImgBurn, Clonezilla,
+OCS inventory, Icinga, Skolelinux, SystemRescueCD og mykje meir.</p>
+
+<p><strong>Hvilken strategi tror du er den rette å bruke for å få
+skoler til å ta i bruk fri programvare?</strong></p>
+
+<p>Strategisk må ein fokusere på at sluttbruker eigentleg ikkje er så
+fokusert på at det er fri programvare men at det skal «berre fungere».
+Gjer det enkelt å bruker og ikkje minst å administrere. For Skolelinux
+sin del må ein få eit betre fokus på overganger. Utbytting av servere
+må gå meir automatisk, import og eksport av brukerbase og maskinbase
+med meir må kunne gå enkelt og oppgradering til neste versjon må bli
+mykje meir automatisk og gjennomtesta. Ein må unngå at ein må sette
+opp frå start når ein byter ut ein server eller oppgraderer til neste
+versjon. For å få Skolelinux til å bli eit betre alternativ for skular
+må ein ha fokus på nettlesaren. Denne må bli «up to date» og støtte
+dei protokollar og tillegg som vert brukt av forlag med meir. Etter
+kvart som meir og meir blir flytta ut i «skya» vert dette viktigare og
+viktigare. Ein kunne ynskje og jobbe for at forlag med fleire tar i
+bruk opne standarer, men inntil det skjer, må systemet kunne brukast
+mot desse fagsystema.</p>
+
+<p>For meg har prosjektet med Skolelinux vore ein svært artig og
+lærerik prosess. Miljøet rundt er ikkje enormt stort, dog stort nok,
+men det er svært hjelpevillig og engasjert.</p>

- <title>Lets make hardware dongles easier to use in Debian</title>

- <description><p>One thing that annoys me with Debian and Linux distributions in
-general, is that there is a great package management system with the
-ability to automatically install software packages by downloading them
-from the distribution mirrors, but no way to get it to automatically
-install the packages I need to use the hardware I plug into my
-machine. Even if the package to use it is easily available from the
-Linux distribution. When I plug in a LEGO Mindstorms NXT, it could
-suggest to automatically install the python-nxt, nbc and t2n packages
-I need to talk to it. When I plug in a Yubikey, it could propose the
-yubikey-personalization package. The information required to do this
-is available, but no-one have pulled all the pieces together.</p>
-
-<p>Some years ago, I proposed to
-<a href="http://lists.debian.org/debian-devel/2010/05/msg01206.html">use
-the discover subsystem to implement this</a>. The idea is fairly
-simple:
-
-<ul>
-
-<li>Add a desktop entry in /usr/share/autostart/ pointing to a program
- starting when a user log in.</li>
-
-<li>Set this program up to listen for kernel events emitted when new
- hardware is inserted into the computer.</li>
-
-<li>When new hardware is inserted, look up the hardware ID in a
- database mapping to packages, and take note of any non-installed
- packages.</li>
-
-<li>Show a message to the user proposing to install the discovered
- package, and make it easy to install it.</li>
-
-</ul>
-
-<p>I am not sure what the best way to implement this is, but my
-initial idea was to use dbus events to discover new hardware, the
-discover database to find packages and
-<a href="http://www.packagekit.org/">PackageKit</a> to install
-packages.</p>
-
-<p>Yesterday, I found time to try to implement this idea, and the
-draft package is now checked into
-<a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/">the
-Debian Edu subversion repository</a>. In the process, I updated the
-<a href="http://packages.qa.debian.org/d/discover-data.html">discover-data</a>
-package to map the USB ids of LEGO Mindstorms and Yubikey devices to
-the relevant packages in Debian, and uploaded a new version
-2.2013.01.09 to unstable. I also discovered that the current
-<a href="http://packages.qa.debian.org/d/discover.html">discover</a>
-package in Debian no longer discovered any USB devices, because
-/proc/bus/usb/devices is no longer present. I ported it to use
-libusb as a fall back option to get it working. The fixed package
-version 2.1.2-6 is now in experimental (didn't upload it to unstable
-because of the freeze).</p>
-
-<p>With this prototype in place, I can insert my Yubikey, and get this
-desktop notification to show up (only once, the first time it is
-inserted):</p>
-
-<p align="center"><img src="http://people.skolelinux.org/pere/blog/images/2013-01-09-hw-autoinstall.png"></p>
-
-<p>For this prototype to be really useful, some way to automatically
-install the proposed packages by pressing the "Please install
-program(s)" button should to be implemented.</p>
-
-<p>If this idea seem useful to you, and you want to help make it
-happen, please help me update the discover-data database with mappings
-from hardware to Debian packages. Check if 'discover-pkginstall -l'
-list the package you would like to have installed when a given
-hardware device is inserted into your computer, and report bugs using
-reportbug if it isn't. Or, if you know of a better way to provide
-such mapping, please let me know.</p>
-
-<p>This prototype need more work, and there are several questions that
-should be considered before it is ready for production use. Is dbus
-the correct way to detect new hardware? At the moment I look for HAL
-dbus events on the system bus, because that is the events I could see
-on my Debian Squeeze KDE desktop. Are there better events to use?
-How should the user be notified? Is the desktop notification
-mechanism the best option, or should the background daemon raise a
-popup instead? How should packages be installed? When should they
-not be installed?</p>
-
-<p>If you want to help getting such feature implemented in Debian,
-please send me an email. :)</p>

+download the map type you want. There are 8 different maps available,
+using different colours and data selection. Pick one of Roadmap, Topo
+Summer, Topo Winter, Roadmap II, Topo Summer II, Topo Winter II,
+"Trails - overlay map" and "Cross country - overlay map" (see the web

- <description><p>During Christmas, I have worked a bit on the Debian support for

-NXT</a>. My son and I have played a bit with my NXT set, and I
-discovered I had to build all the tools myself because none were
-already in Debian Squeeze. If Debian support for LEGO is something
-you care about, please join me on the IRC channel
-<a href="irc://irc.debian.org/%23debian-lego">#debian-lego</a> (server
-irc.debian.org). There is a lot that could be done to improve the
-Debian support for LEGO designers. For example both CAD software

+ <title>"Electronic" paper invoices - using vCard in a QR code</title>
+ <link>http://people.skolelinux.org/pere/blog/_Electronic__paper_invoices___using_vCard_in_a_QR_code.html</link>
+ <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/_Electronic__paper_invoices___using_vCard_in_a_QR_code.html</guid>
+ <pubDate>Tue, 12 Feb 2013 10:30:00 +0100</pubDate>
+ <description><p>Here in Norway, electronic invoices are spreading, and the
+<a href="http://www.anskaffelser.no/e-handel/faktura">solution promoted
+by the Norwegian government</a> require that invoices are sent through
+one of the approved facilitators, and it is not possible to send
+electronic invoices without an agreement with one of these
+facilitators. This seem like a needless limitation to be able to
+transfer invoice information between buyers and sellers. My preferred
+solution would be to just transfer the invoice information directly
+between seller and buyer, for example using SMTP, or some HTTP based
+protocol like REST or SOAP. But this might also be overkill, as the
+"electronic" information can be transferred using paper invoices too,
+using a simple bar code. My bar code encoding of choice would be QR
+codes, as this encoding can be read by any smart phone out there. The
+content of the code could be anything, but I would go with
+<a href="http://en.wikipedia.org/wiki/VCard">the vCard format</a>, as
+it too is supported by a lot of computer equipment these days.</p>
+
+<p>The vCard format support extentions, and the invoice specific
+information can be included using such extentions. For example an
+invoice from SLX Debian Labs (picked because we
+<a href="http://www.linuxiskolen.no/slxdebianlabs/donations.html">ask
+for donations to the Debian Edu project</a> and thus have bank account
+information publicly available) for NOK 1000.00 could have these extra
+fields:</p>
+
+<p><pre>
+X-INVOICE-NUMBER:1
+X-INVOICE-AMOUNT:NOK1000.00
+X-INVOICE-KID:123412341234
+X-INVOICE-MSG:Donation to Debian Edu
+X-BANK-ACCOUNT-NUMBER:16040884339
+X-BANK-IBAN-NUMBER:NO8516040884339
+X-BANK-SWIFT-NUMBER:DNBANOKKXXX
+</pre></p>
+
+<p>The X-BANK-ACCOUNT-NUMBER field was proposed in a stackoverflow
+answer regarding
+<a href="http://stackoverflow.com/questions/10045664/storing-bank-account-in-vcard-file">how
+to put bank account information into a vCard</a>. For payments in
+Norway, either X-INVOICE-KID (payment ID) or X-INVOICE-MSG could be
+used to pass on information to the seller when paying the invoice.</p>
+
+<p>The complete vCard could look like this:</p>
+
+<p><pre>
+BEGIN:VCARD
+VERSION:2.1
+ORG:SLX Debian Labs Foundation
+ADR;WORK:;;Gunnar Schjelderups vei 29D;OSLO;;0485;Norway
+URL;WORK:http://www.linuxiskolen.no/slxdebianlabs/
+EMAIL;PREF;INTERNET:sdl-styret@rt.nuug.no
+REV:20130212T095000Z
+X-INVOICE-NUMBER:1
+X-INVOICE-AMOUNT:NOK1000.00
+X-INVOICE-MSG:Donation to Debian Edu
+X-BANK-ACCOUNT-NUMBER:16040884339
+X-BANK-IBAN-NUMBER:NO8516040884339
+X-BANK-SWIFT-NUMBER:DNBANOKKXXX
+END:VCARD
+</pre></p>
+
+<p>The resulting QR code created using
+<a href="http://fukuchi.org/works/qrencode/">qrencode</a> would look
+like this, and should be readable (and thus checkable) by any smart
+phone, or for example the <a href="http://zbar.sourceforge.net/">zbar
+bar code reader</a> and feed right into the approval and accounting
+system.</p>
+
+<p><img src="http://people.skolelinux.org/pere/blog/images/2013-02-12-qr-invoice.png"></p>
+
+<p>The extension fields will most likely not show up in any normal
+vCard reader, so those parts would have to go directly into a system
+handling invoices. I am a bit unsure how vCards without name parts
+are handled, but a simple test indicate that this work just fine.</p>
+
+<p><strong>Update 2013-02-12 11:30</strong>: Added KID to the proposal
+based on feedback from Sturle Sunde.</p>

- <description><p>I was happy to discover a few days ago that the
-<a href="http://www.skolelinux.org/">Skolelinux / Debian Edu</a>
-project also this year received a Christmas present from Another
-Agency in Trondheim. NOK 1000,- showed up on our donation account
-December 24th. I want to express our thanks for this very welcome
-present. As the Debian Edu / Skolelinux project is very short on
-funding these days, and thus lack the money to do regular developer
-gatherings, this donation was most welcome. One developer gathering
-cost around NOK 15&nbsp;000,-, so we need quite a lot more to keep the
-development pace we want. Thus, I hope their example this year is
-followed by many others. :)</p>
-
-<p>The public list of donors can be found on
-<a href="http://www.linuxiskolen.no/slxdebianlabs/donations.html">the
-donation page</a> for the project, which also contain instructions if
-you want to donate to the project.</p>

+
+<p>With kids in the house, one challenge is getting them to sleep
+during the night and wake up when it is morning. I mean, when I
+believe it is morning, and not two hours earlier. In our household we
+have decided that 07:00 is the turning point, but getting the kids to
+sleep until 07:00 is a small challenge every day. They have adapted
+quite well, and rarely wake up at 05:00 any more, but some times wake
+up at times like 05:50, 06:15, 06:30 or 06:45, and it is hard to put
+the awake one to bed again without disturbing and waking the rest.
+And I understand perfectly well that they fail to sleep until 07:00
+some times, as there is no way for them to know if it is before or
+after the magic moment without coming and asking us parents.</p>
+
+<p>But yesterday I came up with a method to solve this problem. It
+involve home automation. A few years ago I bought a
+<a href="http://www.telldus.se/products/tellstick">Tellstick</a> and RF
+switches at the local <a href="http://www.clasohlson.com/">Clas
+Ohlson</a> shop, allowing me to control lights and other electrical
+gadgets using my Linux server. When I moved from the old flat to a
+small house, I put away all this equipment as most of the lighting in
+the house was not using wall sockets and thus not easy to connect to
+the gadgets I had. But recently I bought a
+<a href="http://www.telldus.se/products/tellstick_net">Tellstick
+Net</a> to be able to read sensor input as well as control power
+sockets. I want to control ovens in the basement to avoid the pipes
+to freeze, and monitor the humidity to detect flooding. The default
+setup for Tellstick Net is to be controlled by the vendor web service,
+which to me is a security problem, but it is also possible to build
+ones own
+<a href="http://developer.telldus.com/blog/2012/03/02/help-us-develop-local-access-using-tellstick-net-build-your-own-firmware">firmware
+with local access</A> instead of being controlled by a Swedish
+company, thanks to the release of the GPL licensed firmware source
+code. I plan to get that running before I let it control anything
+important. But while working on this, one idea to make it easier for
+the kids came to me yesterday. We can set up a night light controlled
+by the computer, and turn it automatically on at 07:00. The kids can
+then check the light in the morning to know if they are supposed to
+get up or not. They joined me in setting everything up, and I
+repeated the concept several times before bed times to make sure they
+remembered to check the light before getting up in the morning.</p>
+
+<p>We tested it this morning, and all the kids stayed in bed until
+after 07:00, and every one of them commented on the fact that the
+"morning light" was turned on and signalled that the morning had
+arrived. So this look like a success, and I am excited to see how
+this develops the next few days. :) I really hope this can allow us
+all to sleep a bit longer in the morning.</p>
+
+<p>A nice advantage of this setup is that we can remote control when
+to tell the kids to get up. We do not have to wait until 07:00, and
+can also delay it if we want to.</p>

- <pubDate>Tue, 25 Dec 2012 20:50:00 +0100</pubDate>
- <description><p>Let me start by wishing you all marry Christmas and a happy new
-year! I hope next year will prove to be a good year.</p>
-
-<p><a href="http://www.bitcoin.org/">Bitcoin</a>, the digital
-decentralised "currency" that allow people to transfer bitcoins
-between each other with minimal overhead, is a very interesting
-experiment. And as I wrote a few days ago, the bitcoin situation in
-<a href="http://www.debian.org/">Debian</a> is about to improve a bit.
-The <a href="http://packages.qa.debian.org/bitcoin">new debian source
-package</a> (version 0.7.2-2) was uploaded yesterday, and is waiting
-in <a href="http://ftp-master.debian.org/new.html">the NEW queue</A>
-for one of the ftpmasters to approve the new bitcoin-qt package
-name.</p>
-
-<p>And thanks to the great work of Jonas and the rest of the bitcoin
-team in Debian, you can easily test the package in Debian Squeeze
-using the following steps to get a set of working packages:</p>
-
-<blockquote><pre>
-git clone git://git.debian.org/git/collab-maint/bitcoin
-cd bitcoin
-DEB_MAINTAINER_MODE=1 DEB_BUILD_OPTIONS=noupnp fakeroot debian/rules clean
-DEB_BUILD_OPTIONS=noupnp git-buildpackage --git-ignore-new
-</pre></blockquote>
-
-<p>You might have to install some build dependencies as well. The
-list of commands should give you two packages, bitcoind and
-bitcoin-qt, ready for use in a Squeeze environment. Note that the
-client will download the complete set of bitcoin "blocks", which need
-around 5.6 GiB of data on my machine at the moment. Make sure your
-~/.bitcoin/ directory have lots of spare room if you want to download
-all the blocks. The client will warn if the disk is getting full, so
-there is not really a problem if you got too little room, but you will
-not be able to get all the features out of the client.</p>
-
-<p>As usual, if you use bitcoin and want to show your support of my
-activities, please send Bitcoin donations to my address

+befolkningen, det vil si datalagringsdirektivet.</p>
+
+<p>Hvis du vil vite hva hver enkelt stortingsrepresentant har stemt i

- <title>A word on bitcoin support in Debian</title>
- <link>http://people.skolelinux.org/pere/blog/A_word_on_bitcoin_support_in_Debian.html</link>
- <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/A_word_on_bitcoin_support_in_Debian.html</guid>
- <pubDate>Fri, 21 Dec 2012 23:59:00 +0100</pubDate>
- <description><p>It has been a while since I wrote about
-<a href="http://www.bitcoin.org/">bitcoin</a>, the decentralised
-peer-to-peer based crypto-currency, and the reason is simply that I
-have been busy elsewhere. But two days ago, I started looking at the
-state of <a href="http://packages.qa.debian.org/bitcoin">bitcoin in
-Debian</a> again to try to recover my old bitcoin wallet. The package
-is now maintained by a
-<a href="https://alioth.debian.org/projects/pkg-bitcoin/">team of
-people</a>, and the grunt work had already been done by this team. We
-owe a huge thank you to all these team members. :)
-But I was sad to discover that the bitcoin client is missing in
-Wheezy. It is only available in Sid (and an outdated client from
-backports). The client had several RC bugs registered in BTS blocking
-it from entering testing. To try to help the team and improve the
-situation, I spent some time providing patches and triaging the bug
-reports. I also had a look at the bitcoin package available from Matt
-Corallo in a
-<a href="https://launchpad.net/~bitcoin/+archive/bitcoin">PPA for
-Ubuntu</a>, and moved the useful pieces from that version into the
-Debian package.</p>
-
-<p>After checking with the main package maintainer Jonas Smedegaard on
-IRC, I pushed several patches into the collab-maint git repository to
-improve the package. It now contains fixes for the RC issues (not from
-me, but fixed by Scott Howard), build rules for a Qt GUI client
-package, konqueror support for the bitcoin: URI and bash completion
-setup. As I work on Debian Squeeze, I also created
-<a href="http://lists.alioth.debian.org/pipermail/pkg-bitcoin-devel/Week-of-Mon-20121217/000041.html">a
-patch to backport</a> the latest version. Jonas is going to look at
-it and try to integrate it into the git repository before uploading a
-new version to unstable.
-
-<p>I would very much like bitcoin to succeed, to get rid of the
-centralized control currently exercised in the monetary system. I
-find it completely unacceptable that the USA government is collecting
-transaction data for almost all international money transfers (most are done in USD and transaction logs shipped to the spooks), and
-that the major credit card companies can block legal money
-transactions to Wikileaks. But for bitcoin to succeed, more people
-need to use bitcoins, and more people need to accept bitcoins when
-they sell products and services. Improving the bitcoin support in
-Debian is a small step in the right direction, but not enough.
-Unfortunately the user experience when browsing the web and wanting to
-pay with bitcoin is still not very good. The bitcoin: URI is a step
-in the right direction, but need to work in most or every browser in
-use. Also the bitcoin-qt client is too heavy to fire up to do a
-quick transaction. I believe there are other clients available, but
-have not tested them.</p>
-
-<p>My
-<a href="http://people.skolelinux.org/pere/blog/Now_accepting_bitcoins___anonymous_and_distributed_p2p_crypto_money.html">experiment
-with bitcoins</a> showed that at least some of my readers use bitcoin.
-I received 20.15 BTC so far on the address I provided in my blog two
-years ago, as can be
-<a href="http://blockexplorer.com/address/15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b">seen
-on the blockexplorer service</a>. Thank you everyone for your
-donation. The blockexplorer service demonstrates quite well that
-bitcoin is not quite anonymous and untracked. :) I wonder if the
-number of users have gone up since then. If you use bitcoin and want
-to show your support of my activity, please send Bitcoin donations to
-the same address as last time,

-er referert på følgende:</p>
-

-Når det gjelder retten til opphavsrett for kulturproduktene, mener
-Piratpartiet av levetid + 14 år er tilfredsstillende.
-</blockquote>
-
-<p>Det betyr en vernetid langt ut over det kommersielle livet til de

+<a href="http://people.skolelinux.org/pere/blog/How_to_backport_bitcoin_qt_version_0_7_2_2_to_Debian_Squeeze.html">last
+bitcoin related blog post</a> mentioned that the new
+<a href="http://packages.qa.debian.org/bitcoin">bitcoin package</a> for
+Debian was waiting in NEW. It was accepted by the Debian ftp-masters
+2013-01-19, and have been available in unstable since then. It was
+automatically copied to Ubuntu, and is available in their Raring
+version too.</p>
+
+<p>But there is a strange problem with the build that block this new
+version from being available on the i386 and kfreebsd-i386
+architectures. For some strange reason, the autobuilders in Debian
+for these architectures fail to run the test suite on these
+architectures (<a href="http://bugs.debian.org/672524">BTS #672524</a>).
+We are so far unable to reproduce it when building it manually, and
+no-one have been able to propose a fix. If you got an idea what is
+failing, please let us know via the BTS.</p>
+
+<p>One feature that is annoying me with of the bitcoin client, because
+I often run low on disk space, is the fact that the client will exit
+if it run short on space (<a href="http://bugs.debian.org/696715">BTS
+#696715</a>). So make sure you have enough disk space when you run
+it. :)</p>

-<tr><th>forslag:</th><td>14 års opphavsrett og ingen

-
-<tr><th>grunn:</th><td>Den første loven om opphavsrett spesifiserte 14

-programvarepatenter. Slike patenter gjør dingsene våre dyrere og kan i
-enkelte tilfelle stoppe dem helt.</th></tr>
-</table>
-</blockquote>
-
-<p>Den opprinnelige opphavsretten var på 14 år totalt, ikke 14 år
-etter opphavspersonens død. Jeg tenkte først dette kanskje var
-feilsitering fra Aftenposten, men jeg finner samme påstand i en <a
-href="http://piratpartietnorge.org/om-gramo-og-piratpolitikken/">bloggpost
-fra Geir Aaslid</a> på Piratpartietes offisielle nettsider. Der
-skriver han følgende:</p>
-
-<blockquote>
-Hva vi gjør med opphavsretten er mer komplisert fordi den omfavner så
-mange bransjer, med ulike behov. Enhver reform er en forbedring men
-det er nærliggende å anta at en opphavsrett på levetid + 14 år er
-fullt ut tilfredstillende for musikk, film, litteratur og spill.
-</blockquote>
-
-<p>Det virker dermed på meg som om Piratpartiet allerede har gjort
-retrett fra sin beundringsverdige holdning om at det holdt med 14 års
-total vernetid, til sin nye som tar utgangspunkt i levetiden til
-opphavspersonen. Jeg håper det baserer seg på en misforståelse hos
-piratlederen som blir korrigert tilbake til 14 års total vernetid før
-partiet stiller til valg.</p>
-
-<p>Hvis du lurer på hvilke problemer lang vernetid bringer med seg,
-anbefaler jeg å lese boken <a href="http://free-culture.cc/">Free
-Culture</a> av Lawrence Lessig. Jeg og en liten gruppe andre er igang
-med å
-<a href="https://github.com/petterreinholdtsen/free-culture-lessig">oversette
-boken til bokmål</a> og tar gjerne imot hjelp med oversettelse og
-korrekturlesing.</p>
-
-<p><strong>Oppdatering 2012-12-20</strong>: Oppdaget at
-<a href="http://piratpartietnorge.org/om-gramo-og-piratpolitikken/">bloggposten
-til Geir Aaslid</a> er endret siden i går, og nå inneholder følgende
-avsnitt i stedet for det jeg siterte over:</p>
-
-<blockquote>
-Hva vi gjør med opphavsretten er mer komplisert fordi den omfavner så
-mange bransjer, med ulike behov. Enhver reform er en forbedring men
-det er nærliggende å anta at en opphavsrett lik levetiden, evt + 14 år
-er fullt ut tilfredstillende for mange skapere av musikk, film,
-litteratur og spill. Det er for det meste de store forlagene som er
-imot enhver reform.
-</blockquote>
-
-<p>I tillegg har det dukket opp en setning nederst "Dette dokumentet
-er et utkast til svar på et angrep på Piratpartiet fra Gramo. Det
-endrer seg derfor over tid og den endelige versjonen er det som blir
-publisert på Hardware.no", som tyder på at originalformuleringen ikke
-var veloverveid og sitatet i Aftenposten kanskje var basert på en
-misforståelse.</p>
