Building bridges is hard. But it's a lot easier now than it was five hundred years ago. There's no general reason to think hard things can't get easier.

Your comment is inconsistent with itself. If LightTable's features "had been standard in IntelliJ, Visual Studio, and even Eclipse for years", how is that evidence that Granger et al were being overly ambitious? Wouldn't

I'm reading "Against the Grain" at the moment. It's good, but James Scott (the author) is also clearly a little out of his academic comfort zone in it - Scott is a political scientist & anthropologist, not an archaeo

Yes, that's why I said: "but then I have to think about rounding error. Ugh." Because integer division rounds. (Or truncates, if you prefer.)

I'm tempted to suggest (low / 2) + (high / 2) but then I have to think about rounding error. Ugh. I guess you could write a bunch of nested `if`s to handle the parity errors, assuming you know how your language round

The O(n log n) bound only holds for comparison-based sorts. It's not a matter of time; it's an assumption/precondition of the proof.

It can mostly be done. The OCaml programming language does exactly this - it infers co/contravariance. However, when describing a generic interface which has as part of it a function on types (usually called a "type constructor&qu

See my other comment about co/contravariance as monotonocity/antimonotonicity. Since monotonicity is just functoriality when your categories are posetal, covariance is a special case of functoriality. More generally, you can see

Covariance and contravariance are just monotonicity and anti-monotonicity, applied to types ordered by subtyping. That is: if we have a function on types , say, the function `f` defined by: f(x) = Int -> x Then we say `f` is co
