Verein Computerspende Hamburg and openSUSE

December 15th, 2010 by

This article of the German news magazine Der Spiegel made me aware of the Verein Computerspende Hamburg. A German verein is a non profit association, there are lots in Germany for sports, culture and these kind of stuff.

The Verein Computerspende Hamburg does something very useful: It takes used computer parts that other people do not longer need and refurbish them to working computers again. These computers are handed to people who happen to be in a difficult situation in life. They have to live from Hartz IV which is a kind German social security, following the unemployment benefit which ends after a short period. Hartz IV means very, very little money the people have to make their lives from, too little to buy a new computer.

On the other hand, an increasing amount of the job offerings are posted on the web, so people currently unemployed basically have to search the web, not speaking about preparing the resumes to apply for a job. So how would one do that without a computer?

Computing is not only hardware and well known operating systems and applications are far away from free, so it’s obvious that our great project is a perfect partner here: Not that we only offer a user friendly, easy to install, secure, feature rich and last but not least completely free Linux Distribution, we as a community are also able to help if problems come up, regardless if somebody has money or not and what kind of problem it might be. This is another very concrete example where free software and the FOSS communities help your neighbor, or you – as it is very easy to get into a difficult situation in life.

We sent 500 openSUSE 11.3 DVDs to Hamburg with our warm invitation and welcome to all new users to show up and join our community. So be aware of new kids on the block 🙂

And if you are in Hamburg or around and want to help, I am sure Verein Computerspende can make use of the help of more Geekos, such as installation, first hand user support and probably much more. And if you know of a similar interested initiative, let me know, I am sure I will find more DVDs 😉

openSUSE-Education Live Media including official updates

April 24th, 2009 by

Currently, the openSUSE-Education team is “playing” with the new features of the external build service. As a first result, we’re proud to announce our new live/installable DVD!

This DVD includes:

  • the official updates to all packages since the openSUSE 11.1 release
  • fully pre-configured, ready to run KIWI-LTSP server
  • tons of applications from openSUSE Education repository

You can get it from here: http://download.opensuse.org/repositories/Education/images/iso/ – it’s called openSUSE-Edu-KIWI-LTSP-live*.iso (the openSUSE-Edu-KIWI-LTSP-live-unstable*.iso is for development only). Please watch for the Build Numbers at the end of the ISO-Name if you report bugs in our bugzilla.

Have a look at CyberOrgs blog on the most efficient ways to download the image.

Problem with an selfmade DVD (DVD RECORDER)

April 12th, 2009 by

Symptom:

Since a few days i had an Problem with playing selfmade DVDs. CDs (Audio and *.avi) can be playes. Original DVD’s too. But i have made DVDs with an DVD RECORDER (for TV). Then i burn 2 Movies on the DVD and the Recorder makes an own Menu for the Movies. But if i insert the DVD to the DVD Player, the Device Monitor sayd me, the only three Alternatives are: open in Dolphin, open with Digikam and do nothing. If i choosed Dolphin, dolphin startsand then i see in the bottom an Red Line with the Error “No Access”.

First tries:

I listed the Directory:
lrwxrwxrwx   1 root   root          3 10. Apr 15:24 cdrom -> sr0
lrwxrwxrwx   1 root   root          3 10. Apr 11:45 cdrw -> sr1
lrwxrwxrwx   1 root   root          3 10. Apr 11:45 dvd -> sr0
lrwxrwxrwx   1 root   root          3 10. Apr 11:45 fb -> fb0
brw-rw—-+  1 root   cdrom         11,   0 10. Apr 11:45 sr0
brw-rw—-+  1 root   cdrom   11,   1 10. Apr 11:45 sr1
lrwxrwxrwx   1 root   root          3 10. Apr 11:45 scd0 -> sr0

lrwxrwxrwx   1 root   root          3 10. Apr 11:45 scd1 -> sr
My User is in the Group “cdrom”.

Then  i’ve checked /etc/udev/rules.d 99-my.rules:
There i found: KERNEL==”[sr*[0-9]”,GROUP=”cdrom”,MODE=”0660″

getfacl /dev/sr0 says:

getfacl: Removing leading ‘/’ from absolute path names
# file: dev/sr0

# owner: root

# group: cdrom user::rw-
user:sascha:rw-
group::rw-
mask::rw-
other::—
For sr1 its the same output.

Then i go to  /usr/share/PolicyKit/policy/org.freedesktop.hal.device-access.policy and set the following:
— org.freedesktop.hal.device-access.policy.orig   2008-12-23

</action>

Then i made an reboot, but nothing happens. The same Error is
present.

Today i found out, that all non accessable DVD have the following
Rights:
dr–r–r–  3 sascha 4294967295   88 15. Okt 2006  DVD_VIDEO_RECORDER/
^^^^^^^^^^^^

Strange permissions.

SOLUTION:

Then i created an File in /usr/share/kde4/apps/solid/action with the following:

[Desktop Entry]
X-KDE-Solid-Predicate=[ StorageVolume.ignored == false AND OpticalDisc.availableContent == ‘Data|VideoDvd’ ]
Type=Service
Actions=open;

[Desktop Action open]
Name=Play DVD with video player (Kaffeine)
Exec=kaffeine -d %d DVD
Icon=kaffeine

After an relogin, the new Alternative are present. I can go to open with Kaffeine, and than we have finished this task.

BTW: Please check if KDE3/Kaffeine is installed. Without them the Workaround will not work.

Special Thanks goes to: slowhand/medwin
