How to find a browser plugin supporting a given MIME type
-
18th January 2013
-

Some times I try to figure out which Iceweasel browser plugin to -install to get support for a given MIME type. Thanks to -specifications -done by Ubuntu and Mozilla, it is possible to do this in Debian. -Unfortunately, not very many packages provide the needed meta -information, Anyway, here is a small script to look up all browser -plugin packages announcing ther MIME support using this specification:

- -
-#!/usr/bin/python
-import sys
-import apt
-def pkgs_handling_mimetype(mimetype):
-    cache = apt.Cache()
-    cache.open(None)
-    thepkgs = []
-    for pkg in cache:
-        version = pkg.candidate
-        if version is None:
-            version = pkg.installed
-        if version is None:
-            continue
-        record = version.record
-        if not record.has_key('Npp-MimeType'):
-            continue
-        mime_types = record['Npp-MimeType'].split(',')
-        for t in mime_types:
-            t = t.rstrip().strip()
-            if t == mimetype:
-                thepkgs.append(pkg.name)
-    return thepkgs
-mimetype = "audio/ogg"
-if 1 < len(sys.argv):
-    mimetype = sys.argv[1]
-print "Browser plugin packages supporting %s:" % mimetype
-for pkg in pkgs_handling_mimetype(mimetype):
-    print "  %s" %pkg
-
- -

It can be used like this to look up a given MIME type:

- -
-% ./apt-find-browserplug-for-mimetype 
-Browser plugin packages supporting audio/ogg:
-  gecko-mediaplayer
-% ./apt-find-browserplug-for-mimetype application/x-shockwave-flash
-Browser plugin packages supporting application/x-shockwave-flash:
-  browser-plugin-gnash
-%
-
- -

In Ubuntu this mechanism is combined with support in the browser -itself to query for plugins and propose to install the needed -packages. It would be great if Debian supported such feature too. Is -anyone working on adding it?

- -

Update 2013-01-18 14:20: The Debian BTS -request for icweasel support for this feature is -#484010 from 2008 (and -#698426 from today). Lack -of manpower and wish for a different design is the reason thus feature -is not yet in iceweasel from Debian.

Is there a PHP expert in the building? Debian Edu need help!
+
5th June 2013
+

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: + +

    + +
  1. It is impossible to log into the slbackup web interface + (slbackup-php) using the root user and password. This is + BTS report #700257. + This used to work, but stopped working some time since Squeeze. + Perhaps some obsolete PHP feature was used?
    2. + +
  2. It is not possible to "mass import" user lists in Gosa, neither + using ldif nor using CSV files. The feature was disabled after a + major rewrite of Gosa, and need to be ported to the new system. + This is BTS report + #698840.
    3. + +
+ +

If you can help us, please join us on IRC +(#debian-edu on +irc.debian.org) and provide patches via the BTS.

What is the most supported MIME type in Debian?
-
16th January 2013
-

The DEP-11 -proposal to add AppStream information to the Debian archive, is a -proposal to make it possible for a Desktop application to propose to -the user some package to install to gain support for a given MIME -type, font, library etc. that is currently missing. With such -mechanism in place, it would be possible for the desktop to -automatically propose and install leocad if some LDraw file is -downloaded by the browser.

- -

To get some idea about the current content of the archive, I decided -to write a simple program to extract all .desktop files from the -Debian archive and look up the claimed MIME support there. The result -can be found on the -Skolelinux FTP -site. Using the collected information, it become possible to -answer the question in the title. Here are the 20 most supported MIME -types in Debian stable (Squeeze), testing (Wheezy) and unstable (Sid). -The complete list is available from the link above.

Debian Edu interview: Cédric Boutillier
+
4th June 2013
+

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.

Using modalias info to find packages handling my hardware
-
15th January 2013
-

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.

Åpent møte på onsdag om bruken av Microsoft Exchange ved Universitetet i Oslo
+
3rd June 2013
+

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.

+ +

For kun kort tid siden ble det annonsert at det blir et åpent møte +med ledelsen hos universitetet i Oslo med disse planene som tema:

Tid: Onsdag 2013-06-05 kl. 10:00 +
Sted: 9. etasje i Lucy Smiths hus (admin-bygget)

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.

Saken har ført til endel presseoppslag så langt. Her er de jeg har +fått med meg:

Modalias strings - a practical way to map "stuff" to hardware
-
14th January 2013
-

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:

- -
-find /sys -name modalias -print0 | xargs -0 cat | 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 $(find /sys -name modalias -print0 | xargs -0 cat | sort -u); do \
-    echo "$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:

Moved the pymissile Debian packaging to collab-maint
-
10th January 2013
-

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".

How to install Linux on a Packard Bell Easynote LV preinstalled with Windows 8
+
27th May 2013
+

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.

Lets make hardware dongles easier to use in Debian
-
9th January 2013
-

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: - -

    - -
  • Add a desktop entry in /usr/share/autostart/ pointing to a program - starting when a user log in.
    • - -
  • Set this program up to listen for kernel events emitted when new - hardware is inserted into the computer.
    • - -
  • When new hardware is inserted, look up the hardware ID in a - database mapping to packages, and take note of any non-installed - packages.
    • - -
  • Show a message to the user proposing to install the discovered - package, and make it easy to install it.
    • - -
- -

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. :)

How can I install Linux on a Packard Bell Easynote LV preinstalled with Windows 8?
+
25th May 2013
+

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?

Skolelinux-intervju: Nirosan Thiyagalingam
+
24th May 2013
+

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.

How to transform a Debian based system to a Debian Edu installation
+
17th May 2013
+

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:

+ +
    + +
  1. Add skolelinux related APT sources.
    2. +
  2. Create /etc/debian-edu/config with the wanted configuration.
    3. +
  3. Install debian-edu-install to load preseeding values and pull in + our configuration.
    4. +
  4. 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.
    5. +
  5. Run debian-edu-cfengine-D installation to configure everything + that could not be done using preseeding.
    6. +
  6. Ask for a reboot to enable all the configuration changes.
    7. + +
+ +

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.

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

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

+ +

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

+ +

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

+ +

About Debian Edu and Skolelinux

+ +

Debian Edu, also known as Skolelinux, is a Linux distribution based +on Debian providing an out-of-the box environment of a completely +configured school network. Immediatly after installation a school +server running all services needed for a school network is set up just +waiting for users and machines being added via GOsa², a comfortable +Web-UI. A netbooting environment is prepared using PXE, so after +initial installation of the main server from CD, DVD or USB stick all +other machines can be installed via the network.

+ +

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

+ +

Software updates

    +
  • Install freemind (0.9.0) by default, and stop installing vym by + default.
    • +
  • Install chromium (26.0.1410.43) by default.

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. :)

    How to backport bitcoin-qt version 0.7.2-2 to Debian Squeeze
    -
    25th December 2012
    -

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

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

    + +

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

    + +

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

    + +

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