• avoidance of mistakes because of automated configurations
• documentation

Grooveshark lost the fight against RIAA shut down their service…

Grooveshark was a great Social-Media-Service for connecting people through their love for music. I enjoyed it so much to meet people from all over the world who also love the same music as I do.Many independent musicians were able to advertise their talents there. It’s a pity that they had to shutdown this awesome service.

I upgraded my notebook to Debian Jessie now. I just had a few little problems, but most things worked very well. Due to systemd, the bootprocess is fast as hell. Actually I don’t like systemd( because I think that the success of Unix/Linux has it’s roots in the Unix-Philosophy) but it speeds up the boot-process immensely. I had to reinstall the virtualbox-packages. I am using the packages from the repository download.virtualbox.org and the dkms-module wasn’t build correctly. I also compiled the 4.0.0-Kernel, and it works perfectly.

Here is a nice little script for importing the cacert.org-certificates in debian/ubuntu

Today I updated puppet and installed puppetdb. After the installation I tried to connect my puppetmaster with the puppetdb. As soon as I made a “puppet agent -t” I recieved this error:

Now Debian uses “systemd”. There is a way back to the old sysv-init.
