Object-oriented programming is an exceptionally bad idea which could only have originated in California.

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.

Simplicity is prerequisite for reliability.

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 ability of discerning high quality unavoidably implies the ability of identifying shortcomings.

The question of whether a computer can think is no more interesting than the question of whether a submarine can swim.

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

The lurking suspicion that something could be simplified is the world's richest source of rewarding challenges.

Elegance is not a dispensable luxury but a factor that decides between success and failure.

There should be no such thing as boring mathematics.

Mathematicians are like managers - they want improvement without change.

Programming is one of the most difficult branches of applied mathematics; the poorer mathematicians had better remain pure mathematicians.

Don't compete with me: firstly, I have more experience, and secondly, I have chosen the weapons.

Teaching to unsuspecting youngsters the effective use of formal methods is one of the joys of life because it is so extremely rewarding.

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.

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

Perfecting oneself is as much unlearning as it is learning.

The students that, like the wild animal being prepared for its tricks in the circus called "life", expects only training as sketched above, will be severely disappointed: by his standards he will learn next to nothing.

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.

The traditional mathematician recognizes and appreciates mathematical elegance when he sees it. I propose to go one step further, and to consider elegance an essential ingredient of mathematics: if it is clumsy, it is not mathematics.

APL is a mistake, carried through to perfection. It is the language of the future for the programming techniques of the past: it creates a new generation of coding bums.

The use of COBOL cripples the mind; its teaching should, therefore, be regarded as a criminal offense.

Object-oriented programming is an exceptionally bad idea which could only have originated in California.

Aim for brevity while avoiding jargon.

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.

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.

Many mathematicians derive part of their self-esteem by feeling themselves the proud heirs of a long tradition of rational thinking; I am afraid they idealize their cultural ancestors.

The students that, like the wild animal being prepared for its tricks in the circus called 'life', expects only training as sketched above, will be severely disappointed: by his standards he will learn next to nothing.

Mathematicians are like managers they want improvement without change.

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

If we wish to count lines of code, we should not regard them as lines produced but as lines spent.

I became hooked on the idea of being able to shoot an image and process it myself, and end up with a product.

After I'd produced about two dozen pen and ink drawings, one evening I decided that they needed poems to accompany them. I still have no idea where that notion came from, but it took me about two hours to produce verses for these creatures.

Yeah, that's what kind of, we get the idea a little bit yeah, because other people from different countries also try as hard as they can to get a medal or a gold medal in the Olympic Games. And you know, if they can work hard, we can work hard as well.

What's fascinating is that when you write a script, it's almost a stream of consciousness. You have an idea that it means something, but you're not always sure what. Then when you get on the set, the actors teach you.

I also do not like the idea of soft money, these issue ads - people don't know where the money is coming from, millions and millions of dollars outside of the control of a candidate - there's no accountability.

From the beginning, the series has been story driven - I began with a story idea - but research feeds it.

Then I decided I couldn't just crawl in the corner and die, so I started putting pen to paper and wrote some songs. I had no idea what for or who I was going to work with. I tried to find my way and direction.

The idea is, if I can't heal from my art, then how can you heal?

There is sometimes a peculiar confusion in the West that equates progress to whatever is recent or whatever is new, and it is time we understood that progress has nothing to do with the chronology of an idea.

The idea of licking stamps seemed great fun for me.

Learn about the world, the way it works, any kind of science and anthropology, it's really an interesting place we live in. Evolution is a really fantastic idea, even more than the idea of God I think.

It's slightly complicated for people to grasp the idea of a head of state in human form.

As far as I know, only a small minority of mathematicians, even of those with Platonist views, accept the idea that there may be mathematical facts which are true but unknowable.

So my idea of neurotic is spending too much time trying to correct a wrong. When I feel that I'm doing that, then I snap out of it.

I'm into the idea of responsibility and edification and these things have found me and I have found them. I wanted to be in the movie and I made it known to Mike.

Religion has caused more harm than any other idea since the beginning of time. There's nothing good I can say about it. People use it as a crutch.

Many of the Europeans who want Israel to go away don't even know why they do. Nearly a third of those interviewed concede they have no idea what the Israeli-Palestinian conflict is all about. It's enough to know that Israelis are Jews.

It was an idea we had when Al was in the Senate - to organize and moderate an annual conference that would look at government policy through the lens of the family to help identify ways that the family can be supported and strengthened.
