Hack Day

London is the venue for Europe's first Hack Day - hosted by the BBC and Yahoo! in Alexandra Palace, home of the birth of TV broadcasting over half a century ago. Five hundred designers, developers and engineers from Europe and America will learn and build stuff together over two days, all culminating in a big show-and-tell, a few dodgy prizes and a performance by The Rumble Strips!

What do you need to know? The BBC's APIs are all documented at backstage.bbc.co.uk. The Yahoo Developer Network is at developer.yahoo.net, which also includes links to Flickr's services and APIs from Upcoming and del.icio.us.

We've set up a whole load of links for the day itself. There's the Official Blog, this Flickr group, the Official Backnetwork, a Facebook group and an Unofficial Wiki.
