I heard about this not long after it happened, but I didn't know all the details. It didn't seem like a big deal though it was serious for the individuals involved. This is probably the best account and analysis of what occurred.
The Python community has made great strides in their diversity efforts to be more inclusive. PyCon 2013 had 2500 attendees from 41 countries, there were even a number of parents bringing their kids who were learning to program. Even one father and son from South Africa were flown in, so they could attend. Thanks to those outreach efforts 20% of the attendees were women. Last year Pyladies was the only women in tech group there. This year there were four: LadyCoders, Women Who Code, CodeChix and Pyladies again.
Our group is small and I hope we can start growing it again. Because it is small we don't have a formal group structure and so far it's worked pretty well the way it is. As it grows that'll change.
Thanks,
Chris
PS - There was also another incident wherein someone was using an illegal substance in a public area. They were expelled from the conference and banned from the next two. I don't know what the substance was.
