I am a German computer science student, who also works as a part time web-developer with PHP and Zend Framework.
I also blog about algorithms and other programming stuff at eliteinformatiker.de. It’s mostly in German, but I also have a section with English articles (which are usually those I think are especially interesting to international audience and cannot be found via Google that easy).
At the moment I’m diving into machine learning more by participating in Kaggle events.
