The list of accepted talks for EuroPython was published with lots of great talks and topics. I got my tutorial on Cython with NumPy accepted, as well as my talk on Fast Async Code with Cython and AsyncIO that I'm giving together with a collegue from Skoobe. I guess both proposals colided too heavily with the current list of hype buzzwords to get rejected. ;-)
Thanks to everyone who voted for them! Hope to see you there!
And in case you're interested in learning Cython from a pro, there are still places left for the extensive Cython training that I'll be giving in Leipzig (DE) next June, 16-17th. It's part of a larger series of courses throughout that week on High-Performance Computing with Python.
