Yesterday, I wrote about the -modalias -values provided by the Linux kernel following my hope for -better -dongle support in Debian. 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.
- -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.
- --Package: package-name -- -
Modaliases: module(modaliasglob, modaliasglob, modaliasglob) -
It is fairly trivial to write code to find the relevant packages -for a given modalias value using this file.
- -An entry like this would suggest the video and picture application -cheese for many USB web cameras (interface bus class 0E01):
- --Package: cheese -- -
Modaliases: cheese(usb:v*p*d*dc*dsc*dp*ic0Eisc01ip*) -
An entry like this would suggest the pcmciautils package when a -CardBus bridge (bus class 0607) PCI device is present:
- --Package: pcmciautils -- -
Modaliases: pcmciautils(pci:v*d*sv*sd*bc06sc07i*) -
An entry like this would suggest the package colorhug-client when -plugging in a ColorHug with USB IDs 04D8:F8DA:
- --Package: colorhug-client -- -
Modaliases: colorhug-client(usb:v04D8pF8DAd*) -
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.
- -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.
- -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 -hw-support-lookup -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.
- -When I use it on a machine with a yubikey inserted, it suggest to -install yubikey-personalization:
- --% ./hw-support-lookup -- -
yubikey-personalization -
% -
When I run it on my Thinkpad X40 with a PCMCIA/CardBus slot, it -propose to install the pcmciautils package:
- --% ./hw-support-lookup -- -
pcmciautils -
% -
If you know of any hardware-package mapping that should be added to -my -database, please tell me about it.
- -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.
- -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 -#debian-devel.
+ +Here is a call for help from the Debian Edu / Skolelinux project. +We have two problems blocking the release of the Wheezy version we +hope to get released soon. The two problems require some with PHP +skills, and we seem to lack anyone with both time and PHP skills in +the project: + +

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 -the -Debian Edu subversion repository: - -
Modalias decoded
- -This document try to explain what the different types of modalias -values stands for. It is in part based on information from -<URL: https://wiki.archlinux.org/index.php/Modalias >, -<URL: http://unix.stackexchange.com/questions/26132/how-to-assign-usb-driver-to-device >, -<URL: http://code.metager.de/source/history/linux/stable/scripts/mod/file2alias.c > and -<URL: http://cvs.savannah.gnu.org/viewvc/dmidecode/dmidecode.c?root=dmidecode&view=markup >. - -
The modalias entries for a given Linux machine can be found using -this shell script:
- --cat $(find /sys -name modalias) | sort -u -- -
The supported modalias globs for a given kernel module can be found -using modinfo:
- --% /sbin/modinfo psmouse | grep alias: -alias: serio:ty05pr*id*ex* -alias: serio:ty01pr*id*ex* -% -- -
PCI subtype
- -A typical PCI entry can look like this. This is an Intel Host -Bridge memory controller:
- --pci:v00008086d00002770sv00001028sd000001ADbc06sc00i00 -- -
This represent these values:
- -- v 00008086 (vendor) - d 00002770 (device) - sv 00001028 (subvendor) - sd 000001AD (subdevice) - bc 06 (bus class) - sc 00 (bus subclass) - i 00 (interface) -- -
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).
- -Not sure how to figure out the interface value, nor what it -means.
- -USB subtype
- -Some typical USB entries can look like this. This is an internal -USB hub in a laptop:
- --usb:v1D6Bp0001d0206dc09dsc00dp00ic09isc00ip00 -- -
Here is the values included in this alias:
- -- 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) -- -
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:
- --usb:v0AC8p3420d5000dcEFdsc02dp01ic01isc01ip00 -- -
usb:v0AC8p3420d5000dcEFdsc02dp01ic01isc02ip00 -
usb:v0AC8p3420d5000dcEFdsc02dp01ic0Eisc01ip00 -
usb:v0AC8p3420d5000dcEFdsc02dp01ic0Eisc02ip00 -
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.
- -ACPI subtype
- -The ACPI type is used for several non-PCI/USB stuff. This is an IR -receiver in a Thinkpad X40:
- --acpi:IBM0071:PNP0511: -- -
The values between the colons are IDs.
- -DMI subtype
- -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:
- --dmi:bvnIBM:bvr1UETB6WW(1.66):bd06/15/2005:svnIBM:pn2371H4G:pvrThinkPadX40:rvnIBM:rn2371H4G:rvrNotAvailable:cvnIBM:ct10:cvrNotAvailable: -- -
The values present are
- -- 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) -- -
The chassis type 10 is Notebook. Other interesting values can be -found in the dmidecode source:
- -- 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 -- -
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.
- -SerIO subtype
- -This type is used for PS/2 mouse plugs. One example is from my -test machine:
- --serio:ty01pr00id00ex00 -- -
The values present are
- -- ty 01 (type) - pr 00 (prototype) - id 00 (id) - ex 00 (extra) -- -
This type is supported by the psmouse driver. I am not sure what -the valid values are.
- -Other subtypes
- -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.
- -Looking up kernel modules using modalias values
- -To check which kernel modules provide support for a given modalias, -one can use the following shell script:
- -- for id in $(cat $(find /sys -name modalias)|sort -u); do \ - echo "$id" ; \ - /sbin/modprobe --show-depends "$id"|sed 's/^/ /' ; \ - done -- -
The output can look like this (only the first few entries as the -list is very long on my test machine):
- -- acpi:ACPI0003: - insmod /lib/modules/2.6.32-5-686/kernel/drivers/acpi/ac.ko - acpi:device: - FATAL: Module acpi:device: not found. - acpi:IBM0068: - insmod /lib/modules/2.6.32-5-686/kernel/drivers/char/nvram.ko - insmod /lib/modules/2.6.32-5-686/kernel/drivers/leds/led-class.ko - insmod /lib/modules/2.6.32-5-686/kernel/net/rfkill/rfkill.ko - insmod /lib/modules/2.6.32-5-686/kernel/drivers/platform/x86/thinkpad_acpi.ko - acpi:IBM0071:PNP0511: - insmod /lib/modules/2.6.32-5-686/kernel/lib/crc-ccitt.ko - insmod /lib/modules/2.6.32-5-686/kernel/net/irda/irda.ko - insmod /lib/modules/2.6.32-5-686/kernel/drivers/net/irda/nsc-ircc.ko - [...] -- -

+ +It has been a while since my last English +Debian Edu and Skolelinux +interview last November. But the developers and translators are still +pulling along to get the Wheezy based release out the door, and this +time I managed to get an interview from one of the French translators +in the project, Cédric Boutillier.
+ +Who are you, and how do you spend your days?
+ +I am 34 year old. I live near Paris, France. I am an assistant +professor in probability theory. I spend my daytime teaching +mathematics at the university and doing fundamental research in +probability in connexion with combinatorics and statistical physics.
+ +I have been involved in the Debian project for a couple of years +and became Debian Developer a few months ago. I am working on Ruby +packaging, publicity and translation.
+ +How did you get in contact with the Skolelinux / Debian Edu +project?
+ +I came to the Debian Edu project after a call for translation of +the +Debian Edu manual for the release of Debian Edu Squeeze. Since +then, I have been working on updating the French translation of the +manual. + +
I had the opportunity to make an installation of Debian Edu in a +virtual machine when I was preparing localised version of some screen +shots for the manual. I was amazed to see it worked out of the box and +how comprehensive the list of software installed by default was.
+ +What amazed me was the complete network infrastructure directly +ready to use, which can and the nice administration interface provided +by GOsa². What pleased +me also was the fact that among the software installed by default, +there were many "traditional" educative software to learn languages, +to count, to program... but also software to develop creativity and +artistic skills with music (Ardour, +Audacity) and +movies/animation (I was especially thinking of +Stopmotion).
+ +I am following the development of Debian Edu and am hanging out on +#debian-edu. +Unfortunately, I don't much time to get more involved in this +beautiful project.
+ +What do you see as the advantages of Skolelinux / Debian +Edu?
+ +For me, the main advantages of Skolelinux/Debian Edu are its +community of experts and its precise documentation, as well as the +fact that it provides a solution ready to use.
+ +I would add also the fact that it is based on the rock solid Debian +distribution, which ensures stability and provides a huge collection +of educational free software.
+ +What do you see as the disadvantages of Skolelinux / Debian +Edu?
+ +Maybe the lack of manpower to do lobbying on the +project. Sometimes, people who need to take decisions concerning IT do +not have all the elements to evaluate properly free software +solutions. The fact that support by a company may be difficult to find +is probably a problem if the school does not have IT personnel.
+ +One can find support from a company by looking at +the +wiki dokumentation, where some countries already have a number of +companies providing support for Debian Edu, like Germany or +Norway. This list is easy to find readily from the manual. However, +for other countries, like France, the list is empty. I guess that +consultants proposing support for Debian would be able to provide some +support for Debian Edu as well.
+ +Which free software do you use daily?
+ +I am using the KDE Plasma Desktop. But the pieces of software I use +most runs in a terminal: Mutt and OfflineIMAP for emails, latex for +scientific documents, mpd for music. VIM is my editor of choice. I am +also using the mathematical software +Scilab and +Sage (built from +source as not completely packaged for Debian, yet). + +
Do you have any suggestions for teachers interested in +using the free software in Debian to teach mathematics and +statistics?
+ +I do not have any "nice" recommendations for statistics. At our +university, we use both R and +Scilab to teach statistics and probabilistic simulations. For +geometry, there are nice programs:
+ +-
+
+
- drgeo and +kig to do +constructions in planar geometry + +
- kali +to discover symmetry groups (the so-called wallpapers and frieze +groups), although the interface looks a bit old. + +
I like also +cantor, which +provides a uniform interface to SciLab, Sage, +Octave, etc...
+ +Which strategy do you believe is the right one to use to +get schools to use free software?
+ +My suggestions would be to
+ +-
+
+
- advertise the reduction of costs when free software is used. + +
- communicate about the quality of free software projects, using + well known examples like Firefox, ThunderBird and + OpenOffice.org/LibreOffice. + +
- advertise the living and strong community around the project. + +
- show that it is not more difficult to use than any other + system. + +
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 -pymissile 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. Upstream -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 -gitweb -view or use "git clone -git://anonscm.debian.org/collab-maint/pymissile.git".
+ +Jeg jobber til daglig ved Universitetet +i Oslo, en institusjon som lenge har vektlagt verdien av åpne +standarder og fri programvare. Men noe har endret seg, og for en +liten stund tilbake annonserte USIT at dagens fungerende e-postsystemet +basert på fri programvare skulle byttes ut med Microsoft Exchange og +at Microsoft Outlook skulle bli den best fungerende men antagelig ikke +eneste støttede e-postklienten. Annonseringen har ført til flere +protester og en +underskriftskampanje, initiert av Diana Santos, der så langt 253 +personer har signert. Prosjektet +NIKE (Ny integrert +kalender/e-post) ble initiert for å se på mulige løsninger med +utgangspunkt i at en kombinert epost/kalenderløsning var påkrevd, og +prosjektet +NIKE-implementasjon +er igang med å rulle ut MS Exchange ved Universitetet i Oslo.

Det kan være en god plass å stille opp hvis en som meg ikke tror +valget av Microsoft Exchange som sentral epostinfrastruktur er et +heldig valg for Norges ledende forskningsuniversitet, men at en er mer +tjent med å selv +beholde +kontrollen over egen infrastruktur.

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.
- -Some years ago, I proposed to -use -the discover subsystem to implement this. The idea is fairly -simple: +
+Included in Debian Edu / +Skolelinux, there are quite a lot of educational software. +Created to help teachers teach, and pupils learn. We have tried to +tag them all using debtags use::learning and role::program, and using +the debtags I was happy to be able to create a collage of the +educational software packages installed by default, sorted by the +debtag field. Here it is. Click on a image to learn more about the +program.

+ -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 -PackageKit to install -packages.
- -Yesterday, I found time to try to implement this idea, and the -draft package is now checked into -the -Debian Edu subversion repository. In the process, I updated the -discover-data -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 -discover -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).
- -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):
- -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.
- -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.
- -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?
- -If you want to help getting such feature implemented in Debian, -please send me an email. :)

During Christmas, I have worked a bit on the Debian support for -LEGO Mindstorm -NXT.

+ +Two days ago, I asked +how +I could install Linux on a Packard Bell EasyNote LV computer +preinstalled with Windows 8. I found a solution, but am horrified +with the obstacles put in the way of Linux users on a laptop with UEFI +and Windows 8.
+ +I never found out if the cause of my problems were the use of UEFI +secure booting or fast boot. I suspect fast boot was the problem, +causing the firmware to boot directly from HD without considering any +key presses and alternative devices, but do not know UEFI settings +enough to tell.
+ +There is no way to install Linux on the machine in question without +opening the box and disconnecting the hard drive! This is as far as I +can tell, the only way to get access to the firmware setup menu +without accepting the Windows 8 license agreement. I am told (and +found description on how to) that it is possible to configure the +firmware setup once booted into Windows 8. But as I believe the terms +of that agreement are completely unacceptable, accepting the license +was never an alternative. I do not enter agreements I do not intend +to follow.
+ +I feared I had to return the laptops and ask for a refund, and +waste many hours on this, but luckily there was a way to get it to +work. But I would not recommend it to anyone planning to run Linux on +it, and I have become sceptical to Windows 8 certified laptops. Is +this the way Linux will be forced out of the market place, by making +it close to impossible for "normal" users to install Linux without +accepting the Microsoft Windows license terms? Or at least not +without risking to loose the warranty?
+ +I've updated the +Linux Laptop +wiki page for Packard Bell EasyNote LV, to ensure the next person +do not have to struggle as much as I did to get Linux into the +machine.
+ +Thanks to Bob Rosbag, Florian Weimer, Philipp Kern, Ben Hutching, +Michael Tokarev and others for feedback and ideas.

Og et godt nytt år til dere alle!
+ +I've run into quite a problem the last few days. I bought three +new laptops for my parents and a few others. I bought Packard Bell +Easynote LV to run Kubuntu on and use as their home computer. But I +am completely unable to figure out how to install Linux on it. The +computer is preinstalled with Windows 8, and I suspect it uses UEFI +instead of a BIOS to boot.
+ +The problem is that I am unable to get it to PXE boot, and unable +to get it to boot the Linux installer from my USB stick. I have yet +to try the DVD install, and still hope it will work. when I turn on +the computer, there is no information on what buttons to press to get +the normal boot menu. I expect to get some boot menu to select PXE or +USB stick booting. When booting, it first ask for the language to +use, then for some regional settings, and finally if I will accept the +Windows 8 terms of use. As these terms are completely unacceptable to +me, I have no other choice but to turn off the computer and try again +to get it to boot the Linux installer.
+ +I have gathered my findings so far on a Linlap page about the +Packard Bell +EasyNote LV model. If you have any idea how to get Linux +installed on this machine, please get in touch or update that wiki +page. If I can't find a way to install Linux, I will have to return +the laptop to the seller and find another machine for my parents.
+ +I wonder, is this the way Linux will be forced out of the market +using UEFI and "secure boot" by making it impossible to install Linux +on new Laptops?
I was happy to discover a few days ago that the -Skolelinux / Debian Edu -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 15 000,-, 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. :)
- -The public list of donors can be found on -the -donation page for the project, which also contain instructions if -you want to donate to the project.
+ +En ting +Skolelinux-prosjektet har +hatt mye glede av er studentprosjekter. F.eks. er +stillbildeanimasjonssystemet +Stopmotion resultat av et studentprosjekt i Skolelinux. De siste +månedene har en ivrig student veiledet av Marius Kotsbak i +FRiSK testet hva en +kan få til med en datamaskin til NOK 400,- (antagelig 1700,- med +skjerm, tastatur og mus) når det brukes i Skolelinux. Jeg spurte han +om et intervju.
+ +Hvem er du, og hva driver du med til daglig?
+ +Jeg heter Nirosan Thiyagalingam. Jeg er 24 år og studerer +dataingeniør studiet ved Høgskolen i Sør Trøndelag. Interessen for +data har siden ung alder vært tilstede og jeg har i tillegg alltid +vært glad i å lære nye ting. Med teknologi som endres svært hurtig er +det alltid noe nytt å lære. Noe som igjen har gjort det svært +interessant å følge med på utviklingen. Jeg valgte dataingeniør +studiet grunnet ønske om å lære enda mer om programmering og utvikling +av store systemer.
+ +Hvordan kom du i kontakt med Skolelinux-prosjektet?
+ +Skolelinux prosjektet hørte jeg først om i media. Men det var først +når jeg skulle velge bacheloroppgave at jeg fattet mer interesse for +prosjektet. Et enkelt søk på nettet førte meg til skolelinux sine +hjemmesider. Informasjonen jeg fant der gjorde meg enda nysgjerrig og +jeg valgte derfor en oppgave som gikk ut på å få en +Raspberry PI. Altså en +ultra-billig datamaskin til å kjøre Debian Edu på lik linje med +vanlige datamaskiner. I løpet av prosjektet ble det gjort mye +forskning på nettet. Det var mye jeg måtte forstå rundt hvordan +operativsystemet Linux fungerte før jeg kunne angripe +problemet. Prøvde først å finne ut hvordan man kunne transformere en +vanlig installasjon av Skolelinux til Raspberry PI, men dette var +altfor vanskelig å jeg endte opp med mer spørsmål enn svar. Det ble +videre opprettet kontakt med Skolelinux utviklere på IRC der jeg fikk +diskutert hvilken retning jeg burde gå for å få til en fullverdig +løsning. Det ble bestemt at jeg skulle gå for å først installere +Raspian. Dette er et +operativsystem basert på Debian spesiallaget for Raspberry Pi sin +maskinvare. Nå som Debian var installert på datamaskinen gjenstod det +å installere de nødvendige Skolelinux pakkene for å få til et +fullverdig system. Disse pakkene ble installert manuelt i første +omgang, men ble senere installert automatisk via et script som Petter +Reinholdtsen laget. Dette scriptet er så enkel å bruke at man er i +gang med installasjonen i løpet av bare 5 minutter. Ikke nok med det, +alt skjer helt automatisk. Alt i alt er jeg veldig fornøyd med +resultatet av installasjonsprosessen. Raspberry Pi er en veldig svak +maskin og det merkes godt når man har installert Skolelinux på +den. Video og 3D-rendering fungerer utrolig dårlig, men nettsurfing og +kontorprogrammer fungerer godt. Det kan derfor konkluderes med at +datamaskinen er egnet for enkle oppgaver. + +
Jeg syns det er viktig påpeke at dette kun er startfasen av en slik +løsning. På markedet finnes det nå maskiner som har bedre hardware enn +Raspberry Pi. Det er store muligheter for at man kan klare å +installere Skolelinux på disse også, og da forsvinner nok mest +sannsynlig ytelsesproblemene med Video og 3D rendering også.
+ +Det ble også prøvd med en løsning som gjorde at Raspberry Pi +fungerte som en tynnklient. Denne løsningen hadde langt bedre ytelse +med tanke på hastighet og brukeropplevelse. Men også her var video og +3D rendering dårlig. Det ble brukt en liten Linux distribusjon kalt +BerryTerminal for å få til +dette.
+ +Hva er fordelene med Skolelinux slik du ser det?
+ +Fordelen med Skolelinux er mange. At det er gratis er en stor +fordel, men at det er så mange som er med på å utvikle det og +vedlikeholde det er en enda større fordel. Allerede før jeg startet +med prosjektet så jeg mange fordeler, og når jeg nærmet meg sluttfasen +så jeg langt flere. At prosjektet skulle inneha en så høy kvalitet +hadde jeg aldri trodd. En vanlig Skolelinux installasjon har de +nødvendige programmene og funksjonen som både små og store skoler i +tillegg til organisasjoner kan klare seg med. At prosjektet tilbyr en +så komplett løsning er en kjempefordel. Installasjonen er knirkefri +og det er svært enkelt å installere og komme i gang.
+ +Hva er ulempene med Skolelinux slik du ser det?
+ +Ulempene jeg ser med prosjektet er ryddigheten av websidene. Selv +om websidene er enkle og konsise er det allikevel ikke appellerende i +like stor grad som for eksempel +Ubuntu sine sider. Deres side +tilbyr, i tillegg til godt design og presentasjon, en nettbasert +emulator av deres operativsystem. Dette er en stor fordel slik jeg ser +det. Bortsett fra dette ser jeg absolutt ingen ulemper med +Skolelinux-prosjektet.
+ +Hvilken fri programvare bruker du til daglig?
+ +Til daglig er jeg en flittig bruker av det åpne media +sentersystemet XBMC. Det enorme +samfunnet rundt dette prosjektet har gjort dette til et program som +dekker alles behov. Man kan tilpasse det akkurat slik man vil både med +tanke på utseende og funksjoner ved installere plug-ins eller +scripts.
+ +Hvilken strategi tror du er den rette å bruke for å få +skoler til å ta i bruk fri programvare?
+ +Strategien som burde brukes sett fra mine øyne er +markedsføring. Jeg er sikker på at om flere skoler fikk et lite innsyn +i hvor bra Skolelinux er så ville de ikke nølt med å gå over fra noe +annet som koster de store summer. At skolelinux til de grader tilbyr +en så komplett løsning bure komme frem. Enten via reklamekampanjer +eller ved å sende ut folk til skoler for så å la skolenettverk +ansvarlige få teste ut hvordan Skolelinux fungerer i praksis. Om det +i tillegg ble utviklet gode websider og en emulator for å la brukere +prøve operativsystemet ville nok dette ha styrket inntrykket +betraktelig.
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.
- -Bitcoin, 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 -Debian is about to improve a bit. -The new debian source -package (version 0.7.2-2) was uploaded yesterday, and is waiting -in the NEW queue -for one of the ftpmasters to approve the new bitcoin-qt package -name.
- -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:
- -- --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 -
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.
- -As usual, if you use bitcoin and want to show your support of my -activities, please send Bitcoin donations to my address -15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b.
+ +Debian Edu / Skolelinux is +an operating system based on Debian intended for use in schools. It +contain a turn-key solution for the computer network provided to +pupils in the primary schools. It provide both the central server, +network boot servers and desktop environments with heaps of +educational software. The project was founded almost 12 years ago, +2001-07-02. If you want to support the project, which is in need for +cash to fund developer gatherings and other project related activity, +please +donate some money. + +
A topic that come up again and again on the Debian Edu mailing +lists and elsewhere, is the question on how to transform a Debian or +Ubuntu installation into a Debian Edu installation. It isn't very +hard, and last week I wrote a script to replicate the steps done by +the Debian Edu installer.
+ +The script, +debian-edu-bless +in the debian-edu-config package, will go through these six steps and +transform an existing Debian Wheezy or Ubuntu (untested) installation +into a Debian Edu Workstation:
+ +-
+
+
- Add skolelinux related APT sources. +
- Create /etc/debian-edu/config with the wanted configuration. +
- Install debian-edu-install to load preseeding values and pull in + our configuration. +
- Preseed debconf database with profile setup in + /etc/debian-edu/config, and run tasksel to install packages + according to the profile specified in the config above, + overriding some of the Debian automation machinery. +
- Run debian-edu-cfengine-D installation to configure everything + that could not be done using preseeding. +
- Ask for a reboot to enable all the configuration changes. + +
There are some steps in the Debian Edu installation that can not be +replicated like this. Disk partitioning and LVM setup, for example. +So this script just assume there is enough disk space to install all +the needed packages.
+ +The script was created to help a Debian Edu student working on +setting up Raspberry Pi as a +Debian Edu client, and using it he can take the existing +Raspbian installation and +transform it into a fully functioning Debian Edu Workstation (or +Roaming Workstation, or whatever :).
+ +The default setting in the script is to create a KDE Workstation. +If a LXDE based Roaming workstation is wanted instead, modify the +PROFILE and DESKTOP values at the top to look like this instead:
+ ++PROFILE="Roaming-Workstation" +DESKTOP="lxde" ++ +
The script could even become useful to set up Debian Edu servers in +the cloud, by starting with a virtual Debian installation at some +virtual hosting service and setting up all the services on first +boot.
It has been a while since I wrote about -bitcoin, 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 bitcoin in -Debian again to try to recover my old bitcoin wallet. The package -is now maintained by a -team of -people, 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 -PPA for -Ubuntu, and moved the useful pieces from that version into the -Debian package.
- -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 -patch to backport 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. - -
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.
- -My -experiment -with bitcoins 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 -seen -on the blockexplorer service. 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, -15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b.
+ +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.
+ +Software updates
+-
+
- Install freemind (0.9.0) by default, and stop installing vym by + default. +
- Install chromium (26.0.1410.43) by default. +
- Install goplay (0.5-1.1) to make golearn available by default. +
- Updated support for Japanese input methods, now based on + ibus-anthy. +
Other changes
+-
+
+
- Switched default file system from ext3 to ext4 for speed and + reliability improvements. +
- Got rid of unwanted winbind daemon and PAM setup activated because + of 706434. +
- Extended and improved the testsuite tests to detect more possible + problems. +
- Corrected proxy handling to not set http_proxy to a bogus + direct:// URL. +
- Corrected proxy setup for diskless workstations. +
- Corrected PXE setup to use our updated udebs during installation. +
- Made installation handling of low entropy level more robust. +
- Create larger partitions for Roaming workstations and Thin client + servers, to make room for all the software installed. +
- Fix bug in Roaming workstation PAM setup, making it impossible to + log in (706753). +
Known issues
+-
+
+
- IP resolution for the local hostname give useless IPv6 address + (705900). Only install + libnss-myhostname on roaming workstations until it is fixed. +
- DVD images are not yet ready. +
- No mass import of user account data in GOsa (ldif or csv) + available yet (698840). +
- Missing artwork for the KDE desktop (and probably a few others). +
- KDE Debian submenu lacks icons. +
- LXDE menu lacks entry for changing GOsa password + (website). Installing gosa-desktop will be an option. +
- Backup configuration via web interface is impossible due to + password submission problem + (700257). + +

+ +How to report bugs
+ +Jeg ble overrasket over å se at Piratpartiet i -Aftenposten -er referert på følgende:
- --Når det gjelder retten til opphavsrett for kulturproduktene, mener -Piratpartiet av levetid + 14 år er tilfredsstillende. -- -
Det betyr en vernetid langt ut over det kommersielle livet til de -aller fleste opphavsrettsbeskyttede verker, og er i strid med slik i -hvert fall jeg har tolket punkt 5 i -kjerneprogrammet -til Piratpartiet:
- --- -5: Ã ndsverk og patenter: tilbake til start
- --
-- - forslag: 14 års opphavsrett og ingen -programvarepatenter - grunn: Den første loven om opphavsrett spesifiserte 14 -års vernetid. Senere har mediabransjens lobbyister stadig presset -loven mot lengre vern, nå er det 70 år etter forfatters død. Dette -gjør at mange verk glemmes og går tapt, noe som er skadelig for norsk -språk og kultur. Vi til tilbake til start: 14 års -vernetid. Patentloven sier klart at dataprogrammer ikke kan -patenteres. Likevel klarer patentadvokater å lure gjennom -programvarepatenter. Slike patenter gjør dingsene våre dyrere og kan i -enkelte tilfelle stoppe dem helt.
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 bloggpost -fra Geir Aaslid på Piratpartietes offisielle nettsider. Der -skriver han følgende:
- --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. -- -
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.
- -Hvis du lurer på hvilke problemer lang vernetid bringer med seg, -anbefaler jeg å lese boken Free -Culture av Lawrence Lessig. Jeg og en liten gruppe andre er igang -med å -oversette -boken til bokmål og tar gjerne imot hjelp med oversettelse og -korrekturlesing.
- -Oppdatering 2012-12-20: Oppdaget at -bloggposten -til Geir Aaslid er endret siden i går, og nå inneholder følgende -avsnitt i stedet for det jeg siterte over:
- --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. -- -
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.
+ +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:
+ +brickos | alternative OS for LEGO Mindstorms RCX. Supports development in C/C++ |
leocad | virtual brick CAD software |
libnxt | utility library for talking to the LEGO Mindstorms NX |
lnpd | daemon for LNP communication with BrickOS |
nbc | compiler for LEGO Mindstorms NXT bricks |
nqc | Not Quite C compiler for LEGO Mindstorms RCX |
python-nxt | python driver/interface/wrapper for the Lego Mindstorms NXT robot |
python-nxt-filer | simple GUI to manage files on a LEGO Mindstorms NXT |
scratch | easy to use programming environment for ages 8 and up |
t2n | simple 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.
