Notas do Editor
     " A debate in the French Senate on digital rights management has
touched a nerve among consumers and software developers. Particularly in the
digital age, there is no easy solution to simultaneous protection of
consumers' right to fair use, intellectual property and interoperability.
But it's disturbing to see that many view proposed changes to French
copyright law as a threat to the open source business model. The French
Senate is walking a tightrope, and the outcome of the debate will be watched
with great interest worldwide. "

     Obrigado! - "Some people have a very difficult time saying "Thank You."
This is unfortunate because those two words are far more valuable than one
might imagine. Saying thank you is more than being polite; it is
recognition for efforts expended. When you hear "thank you," it means that
someone appreciates your efforts. "Thank you" is probably the least
expensive means of recognition possible, something that should make any
manager happy..."
