Second law: The complexity barrier. Software complexity (and therefore that of bugs) grows to the limits of our ability to manage that complexity.

Testing proves a programmer’s failure. Debugging is the programmer’s vindication.

A design remedy that prevents bugs is always preferable to a test method that discovers them.

A test that reveals a bug has succeeded, not failed.

A good threat is worth a thousand tests.

More than the act of testing, the act of designing tests is one of the best bug preventers known.

First law: The pesticide paradox. Every method you use to prevent or find bugs leaves a residue of subtler bugs against which those methods are ineffective.

One of the saddest sights to me has always been a human at a keyboard doing something by hand that could be automated. It's sad but hilarious.

If you can't test it, don't build it. If you don't test it, rip it out.

Software never was perfect and won't get perfect. But is that a license to create garbage? The missing ingredient is our reluctance to quantify quality.

If the objective of testing were to prove that a program is free of bugs, then not only would testing be practically impossible, but it would also be theoretically impossible.

True vehement love is at the opposite side of sanity.

The National Socialist Party will prevent in the future, by force if necessary, all meetings and lectures which are likely to exercise a depressing influence on the German state.

Primitive does not mean stupid.

To see the greatness of a mountain, one must keep one's distance.

No - the light in Tamani's eyes was much more than a reflection. It was the fire that melted her anger and devastated her resolve, every single time she saw it.

After 'The Poisonwood Bible' was published, several people believed that my parents were missionaries, which could not be further from the truth.

Every day holds the possibility of a miracle.

The path to God is rarely a steady climb upward. We climb, we fall back, and we climb higher again.

Dismiss thoughts of 'good, bad, right, wrong, success, failure' - be spontaneous.

When there is conflict, it's good to step away, even for five minutes, because you could say terrible things that you can't take back, so it's best to walk away.
