Testing shows the presence, not the absence of bugs.

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.

But then it was over too quickly and they pulled away. She knew they couldn't stand there and kiss like a couple on the run in a thriller.

We're too young to want to stop living, because after all, we shouldn't stop something we haven't even started.

What we find is that our brains have colossal things happening in them all the time.

The writer is a writer because he cannot help it. It is a compulsion.

I like the Wu Tang Clan a lot.

What brings me the most joy is stories about progressive thinking. When a mother or father accepts their child for whoever they are... when goodness prevails... blah blah blah. I'm a cheese ball.

A man can't do more than he can - but he can at least do that much.

We cannot do without it, and yet we disgrace and vilify the same. It may be compared to a cage, the birds without despair to get in, and those within despair to get out.

Whatever the dictates of fashion, it seems that those who take the trouble to gain mastery over what happens in consciousness do lead a happier life.

Universities are of course hostile to geniuses, which, seeing and using ways of their own, discredit the routine: as churches and monasteries persecute youthful saints.
