hopefully with $2.3B, they could merge tree-sitter into VSCode Anyway, congrats!!!
We've raised $2.3B in Series D funding from Accel, Andreessen Horowitz, Coatue, Thrive, Nvidia, and Google. We're also happy to share that Cursor has grown to over $1B in annualized revenue and now produces more code than any other agent in the world. This funding will allow

I still don't understand why React doesn't ship with React.ErrorBoundary (It can be done in userspace1!1!!, sure react-error-boundary has 7,8M/week downloads)
👀 React <ErrorBoundary> on v19 A subtle but interesting behavior change is explained here Seems like now it will "fail-fast" and bail out on the first error, while previously it "aggregated" errors

learn OCaml, go into debt if you have to (debt here is to suffer with a package manager and build system issues. LSP is the goat)

I have only 2 ways of working with AI now - non-stop 15 hours, 6 projects at the time, while watching LoL worlds and being x10 productive and forgetting to eat/rest/everything - constantly getting distracted because llms made programming no fun

Only supports yojson and has no dependencies aside from the standard lib I used dune preview and I'm surprised by the DX, we should talk more about it

This is such a great idea that I implemented an ocaml port on my way back from Singapore It will be handy internally at ahrefs for all LLM structured outputs! https://t.co/TpGtVxpQ3S
JSON is token‑expensive for LLMs – just like @mattpocockuk frequently mentions. Meet TOON, the Token‑Oriented Object Notation. 💸 40–60% fewer tokens than JSON 📐 readable & tokenizer-aware Wrap your JSON with `encode` to save half the token cost: https://t.co/UoG9yHmgfg

Warning: The experimental framework I'm working on is now public. It contains GADTs, OCaml 5 effects, and a suspicious lack of monads. Proceed with caution. https://t.co/tK7UYfWgzM

It's my moment. Time to share some stuff and get comfy at talking to the camera
OCaml just lost its biggest influencer, only a couple of months of losing one to C++ 😔 Jk. Anyway, watch the stream. @kitlangton explained EffectTS very well since he was also explaining it to the audiences.
