Just got back from Pycon UK 2008 - here are some impressions.
During the 2-day conference we met many interesting people, most notably the guys from Resolver, among them William Reade who is working on IronClad -- which implements a fake python25.dll on top of IronPython. He presented some good results for Numpy in his lightning talk. This approach is surely something to follow closely and potentially use for PyPy.
We also had lunch and a couple of chats with Jacob Kaplan-Moss from Django fame - he is apparently up to try use PyPy's sandboxing features for one of his projects, cool!
Conference itself was well organized for the 230 attending people - although the venue might be a bit small for next year's EuroPython. Ah, and we gave three well attended talks, find the slides here:
