Music Hack Day Berlin just wrapped up last Saturday and it was spectacular. One of the first Music Hack Days was held in Berlin back in 2009. Given the turnout, hopefully, we wont have to wait wait as long for the next one.
The event was hosted at the Axel Springer Plug & Play Accelerator, an appropriately sized venue with walls covered in what can best be called "interesting" graffiti/art. Turnout was impressive with around 200 folks, 80 of which came from outside Germany.
Hacking started Friday morning, went all through the night, and ended mid-day Saturday. Despite the beautiful weather outside, the hackers were persistent! There were a number of great Rdio hacks making the selection of just one winning project quite difficult.
Commit Beat - Site
Looking at recent commits, GitHub user names are compared to Last.fm usernames, allowing you to listen to the tracks fellow developers were listening to at time of commit. Just click on a row to kick off playback via Rdio.
Winner, best use of Rdio API
Winner (tie), audience favorite
Highlights the best parts of your listening history and allows you to listen via Rdio.
A custom recommendation system that builds an evolving station for you to listen to.
Overall the selection of projects had a good blend of software and hardware. Along with all the APIs available folks brought their own instruments, a Seaboard was made available to hackers, a game made, and a number of digital instruments were created. With great projects, great food, and a great staff it was a model Music Hack Day.
A list of all of the hacks is up at Hacker League.
