Mondo Knows Facts

Git began as a replacement for a proprietary tool

Linus Torvalds wrote the first version in 2005 after a licensing dispute cut Linux off from BitKeeper When the free licence for BitKeeper was withdrawn in April 2005, Torvalds needed a distributed system in which every copy held the full history. He had something working within days and passed maintenance to Junio Hamano within months. Git stores files by the hash of their contents, which lets any copy detect corruption. It sits in Mondo's technology collection, one of 200 facts that each trace back to the reference below.
