Notes

• Thinking in systems 9/5/26 • Chessboards, codebases and coalitions turn out to be the same problem wearing different clothes.
• Migrating a core tab 9/2/26 • Replacing a legacy tab in a shipping app, one screen at a time, without a rewrite anyone had to approve.
• Swift concurrency 8/27/26 • Actors do not remove the concurrency problem, they move it to the boundary where you can see it.
• Chess and codebases 8/19/26 • Both reward positional play, and both punish the move that only works if nothing else changes.
