I learned of this event a few weeks ago from one of the organisers and I reckon it's going to be a cracker. It's less of a language and framework love in, and more of an exploration of the design and development techniques required to meet the needs of modern scalable software systems. Full event schedule can be found here.
Tickets are not yet available but I was talking with Martin Thompson last week and he says they're planning to have them available through Lanyrd for the end of January. The organisers assure me that the tickets will be extremely reasonably priced.
I watched the video of Erik Meijer's talk on "What does it mean to be Reactive?" and it was great fun, but I'm still none the wiser. I'm starting to suspect that "Reactive" is mostly used as an FP buzzword (like "monad") without most people actually knowing what it is. Apart from Meijer and Odersky perhaps.
But I have to admit that every time somebody tries to "explain" these more advanced Scala topics to me, it seems like a blizzard of type signatures that make no sense to my shrinking brain. Maybe I just need to construct a Monad around a Promise of a Future on an Option of an answer...
Chris, you beat me to it with the link to the videos. They appear to be uploading about 1 a day so it'll not be long until they're all up. Even so, there's some quality material there already.
It was a great conference with some real top class material being presented by top class people. Given that it was quite a small affair, perhaps 200 or so people, there was lots of opportunity for post event "networking" to be had with the speakers and other attendees which was excellent and most enjoyable.
In addition to the videos, a couple of the devs from GumTree kept a bit of a diary notebook during the event and they've uploaded them for general consumption.
