There are two ways to write error-free programs; only the third one works.

You can measure a programmer's perspective by noting his attitude on the continuing vitality of FORTRAN.

Simplicity does not precede complexity, but follows it.

The computing field is always in need of new cliches.

Computer Science is embarrassed by the computer.

A year spent in artificial intelligence is enough to make one believe in God.

Some programming languages manage to absorb change, but withstand progress.

A picture is worth 10K words - but only those to describe the picture. Hardly any sets of 10K words can be adequately described with pictures.

If a listener nods his head when you're explaining your program, wake him up.

In software systems it is often the early bird that makes the worm.

It goes against the grain of modern education to teach students to program. What fun is there to making plans, acquiring discipline, organizing thoughts, devoting attention to detail, and learning to be self critical.

It is easier to write an incorrect program than understand a correct one.

The best book on programming for the layman is "Alice in Wonderland"; but that's because it's the best book on anything for the layman.

In computing, turning the obvious into the useful is a living definition of the word "frustration".

Every program has two purposes: The one for which it was written and another for which it wasn't.

LISP programmers know the value of everything and the cost of nothing.

One man's constant is another man's variable.

Fools ignore complexity. Pragmatists suffer it. Some can avoid it. Geniuses remove it.

If your computer speaks English, it was probably made in Japan.

I think it is inevitable that people program poorly. Training will not substantially help matters. We have to learn to live with it.

It is easier to change the specification to fit the program than vice versa.

In English every word can be verbed. Would that it were so in our programming languages.

Don't have good ideas if you aren't willing to be responsible for them.

We toast the Lisp programmer who pens his thoughts within nests of parentheses.

A programming language is low level when its programs require attention to the irrelevant.

If you have a procedure with 10 parameters, you probably missed some.

There are two ways to write error-free programs; only the third one works.

Is it possible that software is not like anything else, that it is meant to be discarded: that the whole point is to always see it as a soap bubble?

In computing, turning the obvious into the useful is a living definition of the word 'frustration'.

The best book on programming for the layman is 'Alice in Wonderland'; but that's because it's the best book on anything for the layman.

When someone says, "I want a programming language in which I need only say what I want done," give him a lollipop.

In programming, as in everything else, to be in error is to be reborn.

Syntactic sugar causes cancer of the semicolon.

Symmetry is a complexity-reducing concept (co-routines include subroutines); seek it everywhere.

Some of the best lessons we ever learn are learned from past mistakes. The error of the past is the wisdom and success of the future.

Truth lies within a little and certain compass, but error is immense.

There is a contest old as Eden, which still goes on - the conflict between right and wrong, between error and truth. In this conflict every human being has a part.

To me, error analysis is the sweet spot for improvement.

This nation was conceived in liberty and dedicated to the principle - among others - that honest men may honestly disagree; that if they all say what they think, a majority of the people will be able to distinguish truth from error.

What is earnest is not always true; on the contrary, error is often more earnest than truth.

On health care, virtually every political error that could be made was made.

Honest error is to be pitied, not ridiculed.

In all science, error precedes the truth, and it is better it should go first than last.

Nine times out of ten, in the arts as in life, there is actually no truth to be discovered; there is only error to be exposed.

The study of error is not only in the highest degree prophylactic, but it serves as a stimulating introduction to the study of truth.

Truth is immortal; error is mortal.

To kill an error is as good a service as, and sometimes even better than, the establishing of a new truth or fact.

A small error in the former will produce an enormous error in the latter.

The most considerable difference I note among men is not in their readiness to fall into error, but in their readiness to acknowledge these inevitable lapses.
