I’ve just created a new project, which takes a Octave/Matlab figure and produces a LaTeX+gnuplot plot from it. The program can be found in the Projects category. Feel free to contact me for improvements or comments.

A little bug in alphadin.bst

August 25th, 2013 No comments

I found a little bug in alphadin.bst. If you use the multibib package in LaTeX in combination with the alphadin.bst bibliography style, it can happen that the “\etalchar” command will be defined twice. This will eventually stop the LaTeX interpreter with an error like this:

LaTeX Error: Command \etalchar already defined.

A simple solution is to edit the alphadin.bst file, locate (under FUNCTION {begin.bib} ) and replace




Sure, I wanted to report that bug but it is not obvious where to report?

Big trouble!

September 9th, 2010 No comments

Yesterday was a bad day for me. I did a really stupid thing.

Never ever mount your (web)server with root permissions under nautilus (with SSH) in your local home directory and chmod at the same time recursively your home.

Guess what happens?! It will automatically chmod all your files on your (web)server too! Remember being root there.

So, to make a long story short: I had to reinstall the whole thing after the nice people from did a fresh install of the virtual server. Luckily i could backup all the important data like the mysql-database or the emails. Maybe this is a good chance to try a different web-server, like cherokee? Lets see, if i can get everything back running as it was before.

From courier to dovecot

September 9th, 2009 No comments


today i needed to re-install syscp, since it got lost from the last upgrade. By doing so, courier and postfix also got removed and instead dovecot was installes. Dovecot additionally fixed my login problems which i had with courier-imap and german umlauts. It also seems to be faster and lighter then courer?

Server Upgrade

September 6th, 2009 No comments

Today, i decided to do some updates on the server. So i updated debian, wordpress and removed roundcube. The reason for removing roundcube was that i screwed the roundcube upgrade. Instead of roundcube, i installed Hastymail. So far, i like it a lot, since it is cleaner and faster then roundcube.
