alt Hacker NewsI don't really get the Bun thing. Bun is running Claude Code which is probably the single most actively used development app there is. You say this was a bad use of LLMs, but it's been in production for a while and I haven't heard of any evidence that Claude Code has increased a significantly larger quantity of errors, segfaults, etc, than before.

I agree that the Bun rewrite is much more reasonable than knee-jerk reactions imply, however:
- I don't think Claude Code is using the Rust version yet in their official build
- Claude Code is not a particularly complicated piece of software from an engineering perspective (nor it's particularly well-engineered, at least at the moment).
So in my book "it runs Claude Code" would be pretty weak evidence that the rewrite is going to be successful (the tests they've done are much better evidence, but that's a topic for another time).
> it's been in production for a while
Huh... it looks to me like bun has yet to cut a release post Zig->Rust port (the latest one on github is still on a branch that says it's written in zig in the readme). I assume that nothing is using the rust version yet...
Which also cuts against the complaints about "of course it works [...] you can put this into your production environment soon!" since they don't seem to be asserting either of those things.
I have yet to hear any evidence that the Rust rewrite was harmful. I have no emotional investment in Bun (which I'd never heard of before the rewrite), or Zig (which I also didn't know about), or Rust (which I think is neat and that's about it), so I'm about as unbiased as you can get and from what I saw the conversion was done well, and I haven't heard of massive bugs resulting from the rewrite.

Seems doubtful, I'd put money on it being something like Visual Studio or Visual Studio Code. Maybe CC could claim the (odious) title of most actively used vibe-coded development app, though.
> Yes, Claude Code uses Bun. In fact, Claude Code relies on it as a core dependency and ships as a self-contained Bun executable.
I... somehow did not know that.
Wait is the new CC running on the vibe coded Bun?
Some people, myself included, think that announcing a conversion from Rust to Zig as an experiment then jumping to putting it in the alpha train for public testing/consumption without any real explanation in the span of around 2 weeks is irresponsible and reckless.
Blogposts were promised, details were hinted, but no, it’s just full steam ahead because the AI worked so well. The converted unit tests all worked, all the synthetic tests are okay, so what are you complaining about?
At some point, it’s less about the technical questions and more about getting that pesky human buy-in.
