Visto como se não executa logo a sentença sobre a má obra, o coração dos
filhos dos homens está inteiramente disposto a praticar o mal.


--Nerd´s sign

If you have four classes, Everybody, Somebody, Anybody, and Nobody, if
Somebody has a bug, it could be Anybody 's fault but Nobody really knows,
while Everybody shares responsibility.

"Programming today is a race between software engineers striving to build
bigger and better idiot-proof programs, and the universe trying to build
bigger and better idiots. So far, the universe is winning." - Rick Cook
