I don't speak German and I've been to every Congress since 2009. My favorite event every year. As mentioned most - or at least the majority - of the talks are in English, and the organizers very much cater to non-German-speaking visitors (e.g. the official wiki - main source of information - is mainly in English; here's last year's: https://events.ccc.de/congress/2016/wiki/Main_Page https://events.ccc.de/congress/2016/wiki/Main_Page). Also the price (iirc 100 EUR for a standard 4-day ticket last time) is ridiculously low given the massive amount of talks, often very high-caliber, and very varied. Check out last year's schedule to get an idea: https://fahrplan.events.ccc.de/congress/2016/Fahrplan/schedule.html https://fahrplan.events.ccc.de/congress/2016/Fahrplan/schedu... And there's so much more besides the talks! They typically open the venue the evening before (26th), and then it goes on 24/7 non-stop until the 30th. Go if you can. I've persuaded various people to come over the years - techies and non-techies alike - and everyone's had a blast.
