I was at You Are In Control Conference 2012 in Reykajvik and spoke about Music Hack Day. Post. Slides.
I was at Deezer BeMyApp Hackday Berlin 2012 and worked on Latefy, an iOS app that fingerprints the music playing around you and adds it to a Deezer playlist. Video. Code. Sadly can't bring it to the app store, because we can't get a license for the fingerprinter :(
