This "Pfingst"(pentecost)-hollyday weekend I attented SIGINT 2010. The event took place at the KOMED event centre located in the MP6 and MP7 buildings of the MediaPark in the centre of Cologne, which is in walking distance from my home. :)

This week I had time to follow the 26c3 remotley from home via video live streams. And this was a really great and inspirational experience to me. Here is what it looked like on my computer during the conference:

This is normally bad news fro Linux users like me. But luckily there is wine.
