Stuart Knightley will get technical talking about 'promises' - take a look at his work with q-connection which is very cool.
Stuart says: "If you've ever been lost in a nest of callbacks you understand that asynchronous operations can easily become unmanageable. Promises can reduce the pain of async programming. In this presentation I'll show you what they are, how to use them, some useful tools and how in the end they can make your code cleaner (and you happier). I'll finish off by taking a quick look at some examples of how far the power of promises go."
Hope you can make it!
