Edsger Dijkstra
Edsger Dijkstra
Edsger Wybe Dijkstra; 11 May 1930 – 6 August 2002) was a Dutch computer scientist. A theoretical physicist by training, he worked as a programmer at the Mathematisch Centrumfrom 1952 to 1962. He was a professor of mathematics at the Eindhoven University of Technologyand a research fellow at the Burroughs Corporation. He held the Schlumberger Centennial Chair in Computer Sciences at the University of Texas at Austin from 1984 until 1999, and retired as Professor Emeritus in 1999...
Edsger Dijkstra quotes about
teamwork people may
In the wake of the Cultural Revolution and now of the recession I observe a mounting pressure to co-operate and to promote "teamwork". For its anti-individualistic streak, such a drive is of course highly suspect; some people may not be so sensitive to it, but having seen the Hitlerjugend in action suffices for the rest of your life to be very wary of "team spirit". Very.
engineering long people
The required techniques of effective reasoning are pretty formal, but as long as programming is done by people that don't master them, the software crisis will remain with us and will be considered an incurable disease. And you know what incurable diseases do: they invite the quacks and charlatans in, who in this case take the form of Software Engineering gurus.
technology people today
Too few people recognize that the high technology so celebrated today is essentially a mathematical technology.
people suffering fool
Several people have told me that my inability to suffer fools gladly is one of my main weaknesses.
luxury people simplicity
How do we convince people that in programming simplicity and clarity - in short: what mathematicians call elegance - are not a dispensable luxury, but a crucial matter that decides between success and failure?
people half four
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 of four; probably it is worse.
clever humility skulls
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.
today bugs sticks
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 each other's programs, bugs included.
thinking profound tools
The tools we use have a profound and devious influence on our thinking habits, and therefore on our thinking abilities.
students impossible programming
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.
silly effort mind
The effort of using machines to mimic the human mind has always struck me as rather silly. I would rather use them to mimic something better.
thinking progress pieces
Progress is possible only if we train ourselves to think about programs without thinking of them as pieces of executable code.
intelligent thinking numbers
Lisp has jokingly been called "the most intelligent way to misuse a computer". I think that description is a great compliment because it transmits the full flavor of liberation: it has assisted a number of our most gifted fellow humans in thinking previously impossible thoughts.
quality ability identifying
The ability of discerning high quality unavoidably implies the ability of identifying shortcomings.
