At the end of last year, I attended the Chaos Communication Congress (39c3) of the Chaos Computer Club (CCC)1 for the first time in Hamburg. For four days, the Congress feels like its own open and welcoming world – full of nerds of all generations.

Alongside many technical talks, the Congress also features a large number of contributions dealing with the ethical and political impact of technology on society. Many of these talks are easy to follow even without a deep technical background and are often surprisingly entertaining. A large part of the program is recorded and made publicly available shortly after the event on media.ccc.de. Some talks are in German, others in English – and for many recordings, translated audio tracks (e.g. German/English) can be selected or downloaded directly from the video page.

A few recommendations to get an impression of the Congress:

Finally, I find myself agreeing with Marc-Uwe Kling, who in his talk Die Känguru-Rebellion: Digital Independence Day calls for a regular Digital Independence Day from minute 42:24 onwards. A small, low-threshold invitation to occasionally question one’s own digital habits. If you are curious, have a look and feel free to join in. More information is available at di.day (website in German; talk in German with English audio track).

PS: If you want to bookmark talks or download already published recordings, you might want to take a look at Chaosflix4, an unofficial Android app for CCC videos.

PPS: If you are generally interested in the history and self-image of the CCC, I can recommend the documentary “Alles ist Eins. Außer der 0” (2020), for example on YouTube (German).
