If you're a developer and interested in working with some cool technologies at a BBC hack day, then check out Mashed 08. Being held in London at the Alexandra Palace on June 21-22, this is the BBC's very own "Hack Day", allowing developers to get creative over the course of a weekend.

Microsoft is one of the partners (O'Reilly is another) and entrance is free for all registered participants. If you're interested then you might also like to know there will be Windows Live involvement, with some of us from LiveSide also in attendance. We want to see what cool things people can build with Windows Live, and hopefully we'll be showcasing some of the projects during and after the event.

The Microsoft tickets have just been made available - Register for them now as they will go extremely quickly!

Register for tickets UPDATE: Ticket allocation has closed and the event is now sold out.
