I use regularly another of the side projects of Linus: http://torvalds-family.blogspot.com/2010/01/embroidery-gaah..... My wife has thousands of embroidery files that are nicely displayed in gnome explorer.

Linus made 38 commits over the last year and is on 7th place on count of commits over that period:

I forgot to add the link to Derek - https://github.com/alexellis/derek - a bot to add Developer Certificate of Origin checking and to allow non-admin users to administrate the repos through the use of comments.
