I have been playing with filtering of 3D structures (represented as Arrow tables) via duckdb-wasm… It’s been going pretty well!

one of the first things I add to any ts project now is an `assert` utility: manzt.sh/assert.js
type assertions (`foo as string`) blindly tell the type checker you know more than it does. `assert` is a real runtime check with the same narrowing effect. you'll thank me later when debugging!

just got back from the 4D Nucleome annual meeting.
always fun to be the one poster with fancy images but zero biological novelty (compared to the rest). folks couldn’t have been nicer and more welcoming though!
