It is funny to realize now that his side hobby project became the world's biggest open-source project in history. Oh, and in case you haven't figured it out already, this free operating system was Linux. There are a lot of definitions out there on the web for open-source, and some of them are somewhat confusing for the inexperienced reader, so here is a simplified explanation:
