Program testing can be used to show the presence of bugs, but never to show their absence!
From Edsger Dijkstra
There should be no such thing as boring mathematics.
It is practically impossible to teach good programming to students that have had a prior exposure to BASIC: as potential programmers they are mentally mutilated beyond hope of regeneration.
About the use of language: it is impossible to sharpen a pencil with a blunt axe. It is equally vain to try to do it with ten blunt axes instead.
The competent programmer is fully aware of the limited size of his own skull. He therefore approaches his task with full humility, and avoids clever tricks like the plague.
Computer science is no more about computers than astronomy is about telescopes.
Mathematicians are like managers - they want improvement without change.
Simplicity is prerequisite for reliability.
The question of whether a computer can think is no more interesting than the question of whether a submarine can swim.
Why has elegance found so little following? That is the reality of it. Elegance has the disadvantage, if that's what it is, that hard work is needed to achieve it and a good education to appreciate it.
