Yaaic (Yet another Android IRC client)

Yaaic is an IRC client for Android. It's currently under heavy development. It's open source and you'll find anything regarding Yaaic on Github or on the official website www.yaaic.org. There is a ready-to-use version available at the official Android market.

Graylog-Android

An Android client for Graylog, an rsyslog web interface by Lennart Koopmann. Downloads are available on Github. Graylog has been replaced by Graylog2. Maybe there will be an Android client for the new version too sometime.

Brainfuck-Ruby

A small and hopefully fast Brainfuck interpreter written in Ruby. Why? Just for the fun :) Sourcecode is available on Github too.

Brainfuck-Python

Another Brainfuck interpreter. This time written in Python. I think it's a good lesson when learning a new programming language ;). Source code is available on Github.

ScopePort (Web interface)

ScopePort is a free and open source, easy to use, cost-saving remote monitoring software written by Lennart Koopmann. I contributed some patches to the Web interface. Update: ScopePort seems to be discontinued. There's a backup of the web interface and the server on my Github account.
