- there are now ridiculous vibe coded localisation in VS2026
- task manager started to not report cpu usage correctly recently (the number becomes stalled)
- file explorer display the "loading" icon infinitely on some directories
- and many other things!
One of the thorniest conversions was the session.ts file, which was over 30,000 lines of TypeScript that touched all aspects of the runtime.
For example, until recently the main file for donet runtime GC was more than 50000 lines (it has since been split).
If you've ever used that tool you wouldn't ask this question, since it's obviously fully vibecoded.
Does this impresses/surprises anyone? Two folds: 1) I believe the most optimized JavaScript code could near the performance of this phase 1 port without optimizations. I would have gone with that first, many would think that would not be as cost efficient but: 2) optimizing the rust code will require 10x the effort of the 1 by 1 conversion, just because you now need idiomatic rust code that likely has nothing to do with a plain translation. So defeating the initial gain, there's nothing to do the bottleneck gets just pushed elsewhere
Total: ~1,301,378 lines of Rust.
Production: 832,378 Unit tests: ~469,000 Combined: ~1.30 million lines
On top of the 832K LoC are mostly tests she answered:
> Yeap, 832,378 lines of production Rust. the +800K number is production only; unit tests are another +469K on top.
Greenlets were much faster.
Gil free python gets stuck on all sorts of python locks. It’s slow.
Though it's the same extension that can't keep its session timestamps straight, randomly hides sessions I was just in (then suddenly remembers them after going in and out of a session), and completely shits itself visually when using OpenAI's models, so maybe it really is just the latter.
