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

I found out that most programmers don't like to test their software as intensely as I do.

A well installed microcode bug will be almost impossible to detect.

I think it's a combination of technical and social factors that leads to all the defects in deployed software.

Writing software that's safe even in the presence of bugs makes the challenge even more interesting.

Yet we still see continuous reports of bugs.

As a rule, software systems do not work well until they have been used, and have failed repeatedly, in real applications.

I got bitten by the free software bug in February of 1998 around the time of the Mozilla announcement.

Software is like entropy. It is difficult to grasp, weighs nothing, and obeys the second law of thermodynamics; i.e. it always increases.
