Random thought: a classifier that guesses how old you are by analyzing your Unix command-line style. Also, the fact that I called it the "Unix" command-line should probably be a principle component. 😀

I believe Cliff Stoll guessed that his hacker was not from the West Coast because the hacker used System V arguments instead of BSD arguments.

So you're saying there's a chance? In all seriousness, I think it seems like a plausible thing to do.

NGL... when I see someone like @hal_pomeranz use the CLI I have very real old school unix cli ninja FOMO.
