Dr. Roland Kuhn, of Typesafe, has offered to run a Q&A and live coding session for PHASE; he'll be in town for PhillyETE, so it's the perfect time. (And if there aren't enough questions, he says he has a Reactive workshop he can run instead.)
Roland leads the Akka project at Typesafe; he's a co-author of the Reactive Manifesto; he co-teaches the Coursera course “Principles of Reactive Programming”; and he's a "passionate open-source hakker". He also holds a Dr. rer. nat. in particle physics from TU München and worked in the space industry for several years.
He's also great company over a few beers.
This meeting, and the accompanying refreshments, are sponsored by (and hosted at) Curalate (http://www.curalate.com/).
