Wow, Windows source code has moved to Git. Over 8000 git pushes per day (presumably many of those with multiple commits).
As a point of comparison the Linux kernel was measured at 195 commits per day back in 2014 (http://www.phoronix.com/scan.php?page=news_item&px=MTg3OTE).
I think it’s great that Microsoft accomplished such a huge change with so few problems, and also that they’re talking about it publicly (and contributing source code back!).
