Open Source Software No Longer Optional

In the spring of 1991, a 21-year-old Finnish student named Linus Torvalds sat down to write code that would ultimately revolutionize the world of software development. In a Usenet newsgroup post late that summer, he told the world about his work: "I'm doing a (free) operating system (just a hobby, won't be big and professional like gnu) for 386(486) AT clones," he wrote. "This has been brewing since April and is starting to get ready. I'd like to know what features most people would want. Any suggestions are welcome, but I won't promise I'll implement them:-)."
