Yeah, I used to run a practice and lead a team of people who did software security audits, so I've spent a good deal of time thinking about how to go through all the relevant code as fast as possible and make sure nothing was overlooked.

I appreciate it when:

I. Code is really small, or failing that

II. It's architected in a way that I can be confident that a failure in one part of the code won't affect another part of the code
