[How friendly will this machine be?] Well, I don’t think it’s a matter of friendliness, because ultimately if the program is going to accomplish anything of value, it will probably be relatively complex. -- Gary Kildall (inventor of CP/M, one of the first OS for the micro).

I think it is wise, and only honest, to warn you that my goal is immodest. It is not my purpose to "transfer knowledge" to you that, subsequently, you can forget again. My purpose is no less than to effectuate in each of you a noticeable, irreversable change. I want you to gain, for the rest of your lives, the insight that beautiful proofs are not "found" by trial anf error but are the result of a consciously applied design discipline. I want you to raise your quality standards. I mean, if 10 years from now, when you are doing something quick and dirty, you suddenly visualize that I am looking over your shoulders and say to yourself "Dijkstra would not have liked this", well, that would be enough immortality for me. -- E. W. Dijkstra

Il y a très loin de la velléité à la volnt, de la volonté à la résolution, de la résolution au choix des moyens, du choix ds moyens à lapplication. -- Jean-François Paul de Gondi de Retz

Everything should be made as simple as possible, but no simpler. -- Albert Einstein

Some people suggest that machines would be friendlier if input could be in a natural language. But natural language is probably the worst kind of input because it can be quite ambiguous. The process of retrieving information from the computer would be so time-consuming that you would be better off spending that time getting the information directly from an expert. -- Gary Kildall (inventor of CP/M, one of the first OS for the micro).

Acknowledging the negative doesn't mean sniveling [whining, complaining]; it means facing the truth and then moving on. -- George Leonard, Mastery.

Real difficulties can be overcome; it is only the imaginary ones that are unconquerable. ~Theodore N. Vail

When I dare to be powerful - to use my strength in the service of my vision, then it becomes less and less important whether I am afraid. ~Audre Lorde

If you hear a voice within you say “you cannot paint,” then by all means paint and that voice will be silenced. –Vincent Van Gogh

A person who never made a mistake never tried anything new. – Albert Einstein
