Free Programs

Once upon a time (in my first year of university), a friend told me about the communist ideals of some Free Software Foundation guru: in an ideal world, every piece of software would be free, and any programmer would be paid from the government (with a tax on computer sales).

Then, I thought that was a marvelous idea, but not realistic, and so I forgot about it.

And now? When I grown, I realized that I made a lot of programs that were paid by some customer and that were hardly resellable, and also some interesting utility that I developed while at the university, paid by the State with a research grant, and that maybe could be helpful to others; in addition to that, the introduction of java brought that nice reality of www.developer.com (ex Gamelan): a community of programmers freely releasing and using components, and so, I realized (in part) that dream of free software: I donate to the public domain what I cannot use for making more money, and I freely use what others developed! This is my contribute; please feel free to use it.
