Program testing can be used to show the presence of bugs, but never to show their absence! — Edsger Dijkstra Copy Share Image
Production speed is severely slowed down if one works with half-time people who have other obligations as well. This is at least a factor… — Edsger Dijkstra Copy Share Image
The computing scientist's main challenge is not to get confused by the complexities of his own making. — Edsger Dijkstra Copy Share Image
Probably I am very naive, but I also think I prefer to remain so, at least for the time being and perhaps for the… — Edsger Dijkstra Copy Share Image
In the good old days physicists repeated each other's experiments, just to be sure. Today they stick to FORTRAN, so that they can share… — Edsger Dijkstra Copy Share Image
Don't compete with me: firstly, I have more experience, and secondly, I have chosen the weapons. — Edsger Dijkstra Copy Share Image
Computer science is no more about computers than astronomy is about telescopes. — Edsger Dijkstra Copy Share Image
The use of anthropomorphic terminology forces you linguistically to adopt an operational view. And it makes it practically impossible to argue about programs independently… — Edsger Dijkstra Copy Share Image
Teaching to unsuspecting youngsters the effective use of formal methods is one of the joys of life because it is so extremely rewarding. — Edsger Dijkstra Copy Share Image
Please don't fall into the trap of believing that I am terribly dogmatical about [the goto statement]. I have the uncomfortable feeling that others… — Edsger Dijkstra Copy Share Image
Several people have told me that my inability to suffer fools gladly is one of my main weaknesses. — Edsger Dijkstra Copy Share Image
