The Python meetup that we arranged was succesful, atleast if we measure only
by the number of people attending. When we started we said that if only 20
people would attend, then we would be very happy :) But the number actually
ended up being close to 50 people. We don't know exactly how many people there
where, but most had signed up - some where just invited.

I gave a talk, which was very originally called 'Scientific Python'. It was
mostly introductory, and evolved around the small pitfalls you might encounter
when switch over from Matlab or a similar language to Numpy Python.
The
slides are here.
