Hi folks,
now that the switch to Mercurial has happened, people are discovering that
their Subversion workflow habits don't quite work. This is because Mercurial
has a distributed philosophy, inlike svn which has the concept of the holy
central server where all operations take place.

Great work!
I think we should try to reconstruct at least stub reports for the remaining
sprints. Here are some notes on what happened at the ones I attended. This is
in no way complete (and fairly Jacob focused, since I remember what I did,
but have a hazy understanding of what others did):
It just struck me that maybe we should register the Pypy project on Freshmeat.
It would increase the visibility of the project as well as increase the
visibility of Python in the more general OpenSource world.

I was just notified that the price of 45 pounds per day we were quoted was per

higher than in Washington DC. Since partners dropped out because of the high

quite flexible for sprints beyond sprint 10. If you are
willing to host a sprint in Heidelberg, we should make sure that we can get
all the logistics to work and then ask the team if they want to do a sprint
