The Laws of Computing….. from source

First law – The Computer is always right.

Lemma one – Programmers are occasionally right.

Second law – The amount of time needed to debug a program is
inversely proprotional to the time allotted for
debugging.
Corollary – Programs never work the first time unless there is
virtually unlimited time to complete the program.

Third law – Any programmer can find 90% of his bugs simply by
explaining his program to an uninterested observer.
Corollary – The uninterested observer may be sleeping, dead,
nonhuman, or, in extreme cases, nonexistant.

Fourth law – The most difficult or nearly impossible programming
problems appear obvious or extremely simple to anyone
with little or no knowledge of programming.
Corollary – Those problems most easily solved by a programmer
appear to be overwhelmingly complicated and marvelous to
the layman.

Fifth law – Computers are never more intelligent than their
programmers.
Corollary – Most computers are incredibly stupid.

Sixth law – The rarest bugs in any operating system or major
programming effort will always show up in a demonstration
of its use to prospective users or customers.
Corollary – These bugs usually cannot be reproduced and therfore
cannot be located.
Lemma one – Customers will never purchase programs which appear to
be riddled with bugs as verified by demonstration.
Paradox – Most programs are unfit for sale.
