it is mostly on the oldschool style hacking but I always heard about this meeting of the ChaosComputerClub in Berlin https://www.ccc.de/en/
Has anyone been there? Worth it? it seems the next one is before the end of the year., anyone going?
Instead I am going for sure to Graz on December 11th and I will visit OLGA (https://wp.realraum.at/olga/), anything you advice me check?
