When Linus Torvalds says he is going to work on a side project he doesn't think small and he doesn’t work slowly.
When he created “Git,” the software source control and collaboration system that runs Linux kernel development, he started writing code on a Sunday (April 3, 2005) and emerged just a few days later with a new revision control system that today is regarded as one of the best pieces of software ever written (second, at least, to Linux, of course).
