On Copyright, Creative Commons and Open Source Software Licenses

Let’s now talk about a topic which interests me quite a bit, especially as a programmer: Copyright. You might already know something about Copyright: you know the classic © symbol and the “All rights reserved” text. You know it restricts by whom and how a creative work can be used. You might also know what Fair Use is and that it allows you to make parodies of films or music. But do you know how to make it so people can easily reuse your work?
