In the software business there are many enterprises for which it is not clear that science can help them; that science should try is not clear either.

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.

I am buoyant and expansive and uncontainable--but I always was so, only I never knew it!

But you've slipped under my skin, invaded my blood and seized my heart

Vilify! Vilify! Some of it will always stick.

Tory plans to cut 'further and faster' would wreck recovery and roll back Labour's many successes.

There are many universes, many dimensions. They are endless. Most of them are not particularly relevant for us. They won't help us. They won't make us happier.

To be a good editor or a good writer, I think you really need to be a great reader first.

People were incredibly kind to our family and went out of their way to help.

The root cause of all the problems we have in the world today is ignorance of course. But most, polarization.

A new degree of intellectual power seems cheap at any price.

I think everybody gets lonely sometimes. I don't know if people can ever understand how you can be in a room full of people and be lonely sometimes.
