A good threat is worth a thousand tests.

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.

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

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

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.

For when you look at the ceiling, or down at the floor, when the trouble's before you, you're begging for more.

I look at people who aren’t us and I hate them.

You're not so tough. No tougher than the man whose blood will spill from your veins.

You will be a failure, until you impress the subconscious with the conviction you are a success. This is done by making an affirmation which 'clicks.'

The glory of God always comes at the sacrifice of self.

Everything in moderation - that's what I live by.

By following the concept of one country, two systems, you dont swallow me up nor I you.

That's why I hate to get started in these jam sessions. I'm always the last one to leave.

Just ask yourself, if we weren't taught to be women, what would we be? (Ask yourself this question even if you're a man, and don't cheat by changing the words.)

One cannot say everything at once.
