Who doesn’t know about having too many projects at hand? Guess I am not different, probably rather on the more excessive side of things here. Having finished my PhD and getting some personal issues sorted out, I feel having capacity and the drive to get my hands dirty again. Among the things I already started are some Clojure open source contributions, game experiments and a few other things. However, I felt this is a good opportunity to put a collection of projects on my website. ...

Being an early adaptor for Construct 2, it was about time to get a game built with it out of the door. I think I bought this in 2011 for 30€ or something like that. With an increasing interest in educational apps and new teaching and learning approaches I finally dug into Construct 2, building a complete, yet simple game. Without further ado: Color Duel can be found an Google Play Screen2 Screen4 Screen8 ...

Pain is inevitable. Suffering is optional. ― Haruki Murakami, What I Talk About When I Talk About Running

Last year I failed miserably on running my first marathon. Severe pain from shin splints forced me to stop running completely while training for Berlin marathon 2012. I really tried to continue running but that was probably the worst thing to do. Finally I realized I had to take a break. I stopped running completely for about three months. Having to do so was disappointing of course. But it also was an important lesson, an opportunity to learn. I thought about why my body shut down. What did I do wrong? Here are three things I learned: ...

Very recently I started to use the very nice Karma Test Runner. I really do recommend to check it out. However I wondered why tests ran very slow sometimes (>20s) and sometimes they where very fast (<1s). Quickly I realised the issue was having the Chrome tab in the background: The Chrome tab which was connected to Karma was one among others. I used the other tabs for web browsing and development, so the Karma tab wasn’t the active tab. This gives it a very low priority and running tests became extremely sluggish. ...

I recently got not only interested in Clojure but also want to utilize it for some image analysis now. OpenCV is a very solid package for image and video analysis. Java bindings have been released for OpenCV at the beginning of 2013. Unfortunately it wasn’t as easy as I expected in the first place to use it from Clojure. I would like to show you how to do it. Here is an outline of the necessary steps: ...
