We have proof automation now
I've long had a soft spot for dependently-typed languages like Coq Rocq and Lean. They offer the possibility of a type system capable of encoding and enforcing arbitrarily subtle invariants. The sort of thing that, in regular languages, ends up (at best) as a comment, and which quickly gets lost as the size of the…

Tooltips need a delay, and then they need to skip it
Thinking about UX, a slight delay on a simple tooltip can be nice so that mousing over something quickly doesn't trigger it, but if there are related tooltips nearby, maybe we don't need to wait.

AI 2040 and the cult of intelligence
I used to be one of these people. I read Yudkowsky and was like, OMG recursive self improvement hard takeoff AI is coming. Then I joined the real world and actually tried to do things. At comma, we ship a hardware product of similar complexity to a cell phone, and it’s really hard. Reality has lots of finicky details…

Pac-Man, but you're the ghost
I always felt a little bad for the ghosts in Pac-Man. They patrol the maze, they corner the guy, and then he eats a glowing pellet and suddenly they're the ones running for their lives. So I built a small game where you finally get to play the other side.

Lately I’ve been missing this more and more and ultimately decided to try to do something about it. So I built a…
