OpenHUB's NetBSD Project Statistics
This flew by on Twitter
(thanks ajcc @6LR61!), and I think it's neat
so I point to it here:
BlackDuck's OpenHUB has a number of NetBSD project statistics,
Statis include activity and vulnerability reports,
languages, lines-of-code statistics (with comment and blank lines),
30 day and 12 month activity reports with commit and contributor
numbers, number of contributers per month since 1993 and more.
In a nutshell, NetBSD consists of 5902 years of effort.
Have a look!
