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.

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

The question of whether computers can think is like the question of whether submarines can swim.

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

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

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

The purpose of abstraction is not to be vague, but to create a new semantic level in which one can be absolutely precise.

Simplicity and elegance are unpopular because they require hard work and discipline to achieve and education to be appreciated.

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

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

Teaching COBOL ought to be regarded as a criminal act.

Mentoring is passion for skills and knowledge-transfer to young people

Our ability to reach unity in diversity will be the beauty and the test of our civilisation.

War is regarded as nothing but the continuation of state policy with other means.

I'm not that keen on fierce dictatorship. I think that sort of the point of working with somebody is them coming up with stuff and feeling free to do that.

I think I'll always want to improve my defense. That's something that can always be better. Not saying it's bad now, just something you should always work on.

I do feel there's certainly some films where you can feel that the directors don't care about the genre and they don't care about their characters.

Life goes on forever like the gnawing of a mouse.

Love, and love alone, is capable of giving thee a happier life.

I'll always continue to work. I've never much depended on anyone but myself, as far as that goes.

Cameras are a lifesaver for very shy people who have nowhere else to hide. Behind a lens they can disguise the fact that they have nothing to say to strangers.
