One man's constant is another man's variable. -- Alan Perlis

Alan Perlis was one of the finest specimens of the Real Programmer breed. Back in the days where Computer Scientists didn't exist, he and his kind were responsible for making many of the decisions that shape our view of computers today. I'm particularly fond of Perlis because of his views on Compuer Science:

I think that it's extraordinarily important that we in computer science keep fun in computing. When it started out, it was an awful lot of fun. Of course, the paying customers got shafted every now and then, and after a while we began to take their complaints seriously. We began to feel as if we really were responsible for the successful, error-free perfect use of these machines. I don't think we are. I think we're responsible for stretching them, setting them off in new directions, and keeping fun in the house. I hope the field of computer science never loses its sense of fun. Above all, I hope we don't become missionaries. Don't feel as if you're Bible salesmen. The world has too many of those already. What you know about computing other people will learn. Don't feel as if the key to successful computing is only in your hands. What's in your hands, I think and hope, is intelligence: the ability to see the machine as more than when you were first led up to it, that you can make it more.
The Structure and Interpretation of Computer Programs by Abelson, Sussman, and Sussman

Unfortunately, things haven't quite turned out like Perlis would have wanted.

Besides of his many contributions to Computer Science, such as his work on ALGOL, Perlis is very well known for his Epigrams on Programming, of which our quote is the first one. I like this quote because it reminds me that there can never be an ultimate truth in programming due to our human condition.

Angolanos e Angolanas,

Consequência dos últimos comentários e das últimas conversas no blog REVOLUCAOEMANGOLA.BLOG.COM , foi escrito um artigo sobre o racismo em Angola no blog.
Os membros deste Blog pretendem desta maneira discutir e analisar as origens, causas e consequências do RACISMO em Angola para que juntos possamos arranjar soluções para este assunto que ainda é muito delicado e que tornou-se quase tabu na sociedade Angolana.

Angolano visita o blog e vem ajudar a combater esta doença que é o RACISMO em Angola!
