There is a misconception about hackers. Richard Stallman is one of them. And so are all the people who wrote the computer programs that make up today's Open Source ecosystem. It's not easy to teach the world when mainstream media front pages use the term in a derogatory way. Stallman's article has quite a lot of interesting links that definitely make the point. After 30 something years, it's time for new generation to learn the real meaning. And it must be taught in schools. And hacking must be encouaged. But first we need to change the English dictionaries, because some define hacker as a synonym with cracker. Okay, this is a must topic in the open source course.
