YOLO? Bun has an extensive test suite and this implementation passed the test suite.

Can we at least try to be a bit more accurate and less hyperbolic?

I will continue to use Bun because the same people that made bun have made this decision. I trusted them one week ago. I have used bun for the past 2 years, and so have many others.

I'm not about to just assume they've become immature idiots yolo'ing stuff overnight. They're still the same people they were a week ago. Or two weeks ago.

Program testing can be used to show the presence of bugs, but never to show their absence! Dijkstra (1970) "Notes On Structured Programming"

LLM generated code is garbage, not because it writes obvious errors. But because it lacks any kind of reasoning - Claude will gladly write you a solution for a problem you never had. Good luck fixing these kind of issues that will never be catched by tests.

Are they the same people though? Their interests, goals, environment, incentives, boss etc etc all changed after they got acquired by Anthropic. Its not uncommon for a big company to acquire a smaller one and completely destroy that product to serve the parent company's goal.

You can go read all the details on Jarred's X account - including the progress, how it was thought out, strategy, that they're aware that it looks like zig still, etc etc etc.

Speaking of environment though, everyone neglects to mention that the Bun core team now has access to Claude Mythos. You think they haven't already run Mythos against this? So they have private access to the best cybersecurity scanner known to man.

Suffice to say, I'm yet to see anything that really worries me in any major way with this.

I've read the details, strategy, extensive test suite etc. I'm sorry, I don't think "they have access to Claude Mythos" is the rationale to it unless you truly believe the marketing 100%.

I think we'll just see how it all turns out. Maybe check back in a year or two on hwo it all goes. Anyone who says they "know" or are "very sure" this is the right path or wrong path is plain stupid IMO. Having seen how things work in big companies with high market visibility, I believe there is non-trivial chance this driven mostly as marketting stunt (particularly in current climate) and decision isn't purely based on best interest of Bun's future and longevity.

> This whole thread is an overreaction. 302 comments about code that does not work. We haven’t committed to rewriting. There’s a very high chance all this code gets thrown out completely.

I ain’t reading a single thing from the guy after this one.

[allthetime]

jarred two weeks ago: "we're probably not going to merge any of this" jarred a few days ago: "bun has been rewritten in rust"

thought out?

You've never changed your mind once you got new information?

By that logic, most politicians making election promises didn’t lie or under delivered. They just changed their minds.

I'm sure macOS has an extensive test suite that Apple runs as well, and yet still people suggest waiting a bit before adopting a new macOS release.

An extensive test suite can prove that you have regressions when you change the code, by showing you one or more newly-failing tests. However, it cannot prove that you don't have any regressions; it can only increase your confidence somewhat.

[atonse]

My argument wasn't that the test suite was perfect, my argument was that this is far from "YOLO" - this is a textbook example of being able to do bigger refactors, etc when you have an extensive test suite.

[teaearlgraycold]

Presumably MacOS has an extensive test suite that it is passing before each disastrous release. Tests matter, but they aren’t the entire story.

[wiseowise]

They can have 100% coverage for all I care, you don’t push 1 mil loc change and call it a day.

They’ve literally sold out to Anthropic.

> this implementation passed the test suite

Didn't they also change the tests to make the re-write pass?

[Pay08]

They did, but they also reverted most of those changes.
