News
31c3: A new dawn
After a hell of a congress in 2013, C3L is glad that some of its members made it again, to join the largest hacker event in the year in Hamburg.
A pity, that not all of the members were so lucky, but for the hacky folks left behind, we offer two different spots to meet-up for Congress Everywhere. So, literally:
No nerd is left behind!
If you are interested in the congress, either join it yourself or by stepping by in on of our locations in .lu
Keep yourself up2date with the most informative links and services on our related page.
