Here's a list of forthcoming talks... and some other stuff I plan to do. You can also see transparencies and/or videos of talks I've given, and a more detailed description of my previous talks and travels.
Our non-profit conference will have around 700 attendees over two-days featuring a "Practice" day with an unconference and workshops (ending with the speakers welcome dinner and flamenco concert) followed by a day of speaker presentations on two tracks. There will be around 16 speakers and three keynotes. We finish off the event with a closing party and a rock concert in a historic castle.47 Degrees organizes Lambda World with the support of various functional communities including the Scala User Groups of Madrid, Malaga, Barcelona, and London, and the Haskell and Java User Groups of Madrid. The event is also supported by The Software Engineering University of Sevilla.
I have invitations from David Spivak and Alan Weinstein that I should follow up on. When I go to the Bay area I should contact Paul Dancstep Stepahin and get a tour of the Exploratorium.
