PyPy code swarm

Following the great success of code_swarm, I recently produced a video that shows the commit history of the PyPy project.

The video shows the commits under the dist/ and branch/ directories, which is where most of the development happens.

In the first part of the video, you can see clearly our sprint based approach: the video starts in February 2003, when the first PyPy sprint took place in Hildesheim: after a lot of initial activity, few commits happened in the next two months, until the second PyPy sprint, which took place in Gothenburg in late May 2003; around the minute 0:15, you can see the high commit rate due to the sprint.

The next two years follow more or less the same pattern: very high activity during sprints, followed by long pauses between them; the most interesting breaking point is located around the minute 01:55; it's January 2005, and when the EU project starts, the number of commits just explodes, as well as the number of people involved.

I also particularly appreciated minute 03:08 aka March 22, 2006: it's the date of my first commit to dist/, and my nickname magically appears; but of course I'm biased :-).

The soundtrack is NIN - Ghosts IV - 34: thanks to xoraxax for having added the music and uploaded the video.

Cool. There was less of a drop off after the eu project ended than I expected!
