The coding sprint was 7 people working full-time on Haiku for a week, with pretty long days (something like 14 hours per day - 9AM to 12AM with two short pauses for lunch and dinner). So you can clearly see the difference between people hacking at Haiku during a few hours of their free time, and what a full-time team could achieve (although the 14 hours per day thing isn’t sustainable for more than one week - this is why we call this a “sprint”).
It also happens that a lot of work had been running in the background that was finally completed and delivered this month. I will run gitstats on the github and haikuports repos again, probably in january or february, so we can see the effect of this and GCI on the overall Haiku activity.
Thanks again to everyone who donated to Haiku inc to make the event possible (it paid for the bedrooms and food for everyone)!
