@tclem

@joshvera

• not a lot to report that didn't go well!
• would like to have more design conversations at beginning of week
• lost track a little bit on where progressive diff and related projects are

all

• a bit hard to track various teams

What did you learn?

@tclem

• how tree-sitter works. the base library, the node compiler, each of the grammars.

@rewinfrey

• api difference between named nodes in tree-sitter
• better understanding of how we tie into tree-sitter API via the FFI

@joshvera

• tree-sitter APIs that we aren't using
• split diff output is slow!
• about measures of probability distributions that are multi-dimensional
