[pypy-dev] Paris sprint report conclusion
hpk at trillke.net
Wed Oct 26 00:01:59 CEST 2005
two amendments to the Paris sprint report:
- i put some pictures online at http://codespeak.net/~hpk/paris-sprint/
mostly from the rooms and not so much from the impressive city
around, though. Especially not from the nice music club which
Sten an i visited ...
- we also got quite a bit of planing, discussing and decisions done
regarding the upcoming EU project review, which is to take place in
January in Bruxelles. Involved in those reporting/planning activities
were Bea, Jacob, Laura, Carl and me.
Also i was quite happy how the new organisational idea of
working in discussion groups (and even larger pairings) worked
out. Especially when we get larger sprint assemblies i think
it makes sense to evolve this idea some more.
