Any time someone quotes a law named after some random person, it looks like a stuffy "I know something you don't." Amdahl is probably the only name here that deserves it, and it's a real law. I'd be fine if Eric Brewer put his name on CAP too, also a real law.

YAGNI and "you will ship the org chart" are the two most commonly useful things to remember, but they aren't laws.
