On August 25, 1991, Linus Torvalds wrote a message that changed the world. He didn’t expect that when he wrote it, that’s clear from the message and some of the replies. He had something he wanted to share with his fellow hobbyists, and he wanted some feedback. He was working on a project, an operating system he called Linux. And on that Sunday afternoon, he announced Linux for the first time by posting a message to a Usenet group called comp.os.minix.
