I was surprisingly called: I am one of the best three in this year's Welfenlab Competition, again. That's a computer science competition for pupils and I took place for the fourth time there. Every year I became on place better, therefore I hope, that it will be the first place this year.

But it was much more difficult to estimate how much time it took me, which I was asked during the conversation. In the end I estimated that it took me 200 hours ore more. Anyway I have no idea whether this number is correct or completely wrong.
