Counterexamples: crypto keys, stock price history, weather observations, radio telescope recordings
- marcta 21d agoI think the point is that once it becomes a crypto key, stock price, weather observation, whatever, the datum ceases to be random and becomes arbitrary.
- streetfighter64 16d agoThat is a nonsensical definition of random. If I roll a dice it's random, but if I write down the result it's not? Arbitrary is also quite different from random. Bad passwords are arbitrary, good passwords are random. If you ask a human to give an arbitrary number between 1 and 10, the answer will be 7 way more often than a random number between 1 and 10.
