  • An open letter to Uncle Bob about "Defund The Police"

    You’ve tweeted that you feel “defund the police” is a terrible policy. I hope to change your mind.

    Ignore the name. It is imperfect. In software engineering terms, “defund the police” is similar to the strangler pattern.

    • Go has eliminated most of my off-by-one errors except 0... I mean 1.

      Go’s range operator (for x = range foo) has eliminated the most common trap where I make off-by-one errors.
