Care. I recommend "Programming Pearls" as a good introduction to this concept.

How careful are you with your code? What would you be willing to stake on that answer?

[jrockway]

I'm not saying I care about my code. I'm just saying that one can write bug-free code if one takes the time to do it.

Do you have a piece of code you feel confident about, such that you'd be able to say "here is an existence proof of carefully-written resilient C code of some significant length"? I'd like to take you up on an offer to validate that proof.

I do, but it's unfortunately internal at work. Everything I write for fun has so many library dependencies that you just have to cross your fingers and hope that it will all work as documented :)
