The Green Hackfest - my first hackathon

In this post I'd like to share my experience about the first hackathon that I took part in. It was called The Green Hackfest and took place in Utrecht, the Netherlands on 10-12 October 2014. My team won a price of 1000 EURO, so read on to know what hackathon is, why you should go there, and how to score the price. And of course, pictures, pictures, pictures.
