I was at Mashed (the former Hack Day) this week-end - a really good and geeky event, organised by the BBC at Alexandra Palace. We arrived on the Saturday morning for some talks, detailing the different things we'd be able to play with over the week-end. Amongst these, a full DVB-T multiplex (apparently, it was the first time since 1956 that a TV signal was broadcasted from Alexandra Palace), lots of data from the BBC Programmes team and a box full of recorded radio content over the last year.
After these presentations, the 24 hours hacking session began. We sat down with Kurt and Ben and wrote a small hack which basically starts from a personal music collection and creates you a playlist of recorded BBC programmes. I will write a bit more about this later today
During the 24 hours hack, we had a Rock Band session on big screen, a real-world Tron game (basically, two guys running with GPS phones, guided by two persons watching their trail on a google satellite map :-) ), a rocket launching...
Finally, at 2pm on the Sunday, people presented their hacks. Almost 50 hacks were presented, all extremely interesting. Take a look at the complete list of hacks! On the music side, Patrick's recommender was particularly interesting. It used Latent Semantic Analysis on playcount data for artists in BBC brands and episodes to recommend brands from artists or artists from artists. It gave some surprising results :-) Jamie Munroe resurrected the FPFF Musicbrainz fingerprinting algorithm (which was apparently due to replace the old TRM one before MusicIP offered their services to Musicbrainz) to identify tracks played several times in BBC programmes. The WeDoID3 team talked about creating RSS feeds from embedded metadata in audio and video, but the demo didn't work.
My personal highlight was the hack (which actually won a prize) from Team Bob. Here is a screencast of it:
