So much has changed since that time. There's a great recent talk by Jason Williams and Paul Williams that goes into a lot of detail [1]. Most things now use TypeScript developed natively in VS Code using extensions and a CLI for the additional proprietary bits. That all nicely integrates with agentic workflows, skills, etc. ComDb2 is very relational, very battle-as-in-jepsen-tested and has been open-source for a long time now [2]. C++ is still king, but there's plenty of Python, Go, Rust, Haskell, OCaml, etc. running around.
Ok, lemme ask you this: What has been your favorite Bloomberg keyboard over the years? I preferred the mid-2000s mechanical keyboard before they started going lower profile keys, which suffered from off-center binding when pressing near the edge of a key.
