    This is the most CLEVER phishing scam I’ve ever encountered and for a second it almost got me. Here’s how it works: they ask you to send them the password reset code they have requested gmail send to you, claiming it will stop someone’s access but in fact it just lets them in.

    We should not. doesn’t even address “correctness” in the sense that a Computer Scientist means the word, and—despite the name—it isn’t a form of testing. TDD is mainly an iterative, incremental, evolutionary design technique. Something that many of its advocates overlook.

    In other words, the primary correctness mechanism of TDD, unit testing, is a niche of a niche of a niche of software correctness! This doesn't mean TDD is bad. It DOES mean that we shouldn't treat it as our sole form of correctness, or verification, or even testing.
