Chaos Communication Congress has been organised by the Chaos Computer Club (CCC) since 1981 mainly on the topics of Computer Security, Cryptography, Freedom of Speech, Hacktivism. CCC is the largest association of hackers in Europe, the type of hackers believing in openness, sharing, decentralization, free access to computers and world improvement. Thanks to invitation from Edgeryders and willing to spend some time with them as a warm-up for Opencare project, I attended the Congress for the first time. Costantino and me used to spend the days after Christmas watching the streaming, but it was really worth it to attend it live! 4 Halls with 4 streams of talks from 11.30am to 2.00am in the night made it impossible to follow them all, plus a lot of self-organized sessions where you could meet working groups and new projects. We also had the chance to meet with Mario Behling, part of the software team of Ayab project, who organized a Knithack meeting during the congress.
