I organized the seventh GNU Hackers Meeting in Paris, France.
The 2013 GHM was a successful edition and the second largest to date, with 48 registered participants and 17 talks spread over two full days, plus a pre-meeting day including a keysigning party and a nocturnal visit to the Paris Observatory (thanks to Alain Coulais). I even had custom t-shirts made.
Some friends helped me behind the scenes: I wish to thank Ludovic Courtès, José Marchesi, Sylvain and Sylvestre Ledru; and Thomas Preud'homme, who volunteered to replace Sylvestre at the camera on Saturday. We were kindly hosted by IRILL, for the second time.
The official GHM 2013 page contains presentation slides and videos.
