About JohnL4

Cranky middle-aged white male programmer in North Carolina. My proudest achievement from the ancient days is making an IBM 029 keypunch machine automatically punch sequence numbers into my cards as I punched them. I know more than you think I do and I know less than you think I do.

    Honestly, "left Google for 40-person startup for work-life balance reasons" brought me up short.

    I have long thought writing law is a LOT like writing code. When you actually look at modern laws, they're basically legal patch files.

    I'm guessing not. Earth's heat is way lower down. Think of a cave: always cold. I think what's going on is they're taking the heat out and storing it more efficiently than just dum…
