If debugging is the process of removing software bugs, then programming must be the process of putting them in.

More quotes by Edsger Dijkstra

Image
Simplicity is a great virtue but it requires hard work to achieve it and education to appreciate it. And to make matters worse: complexity sells better.
Edsger Dijkstra
Image
I don't need to waste my time with a computer just because I am a computer scientist.
Edsger Dijkstra
Image
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.
Edsger Dijkstra
Image
If there is one 'scientific' discovery I am proud of, it is the discovery of the habit of writing without publication in mind.
Edsger Dijkstra
Image
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?
Edsger Dijkstra
Image
Aim for brevity while avoiding jargon.
Edsger Dijkstra
Image
The art of programming is the art of organizing complexity.
Edsger Dijkstra
Image
We shall do a much better programming job, provided that we approach the task with a full appreciation of its tremendous difficulty, provided that we stick to modest and elegant programming languages, provided that we respect the intrinsic limitations of the human mind and approach the task as Very Humble Programmers.
Edsger Dijkstra

I mentioned the non-competitive spirit explicitly, because these days, excellence is a fashionable concept. But excellence is a competitive notion, and that is not what we are heading for: we are heading for perfection.

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.
Edsger Dijkstra

Computer science is no more about computers than astronomy is about telescopes, biology is about microscopes or chemistry is about beakers and test tubes. Science is not about tools. It is about how we use them, and what we find out when we do.
Edsger Dijkstra
Image
A most important, but also most elusive, aspect of any tool is its influence on the habits of those who train themselves in its use. If the tool is a programming language this influence is, whether we like it or not, an influence on our thinking habits.... A programming language is a tool that has profound influence on our thinking habits.

Computer science is no more about computers than astronomy is about telescopes.

The use of anthropomorphic terminology forces you linguistically to adopt an operational view. And it makes it practically impossible to argue about programs independently of their being executed.
Edsger Dijkstra
Image
In their capacity as a tool, computers will be but a ripple on the surface of our culture. In their capacity as intellectual challenge, they are without precedent in the cultural history of mankind.
Edsger Dijkstra
Image
Thank goodness we don't have only serious problems, but ridiculous ones as well.
Edsger Dijkstra
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 rest of my life.
Edsger Dijkstra
Image
Progress is possible only if we train ourselves to think about programs without thinking of them as pieces of executable code.
Edsger Dijkstra
Image
Elegance is not a dispensable luxury but a factor that decides between success and failure.

Program testing can be used to show the presence of bugs, but never to show their absence!
