With weird sadness I have to say, we are getting targeted with new kind of marketing. It doesn’t look like it was just technical decision. If anyone was following what was going on X, it was crazy with amount of content about it.

I couldn’t believe before with all fearmongering being marketing, but I am coming to conclusion it is. It’s hard to get any signal over noise in attention economy. They know what they are doing and it’s Deja Vu of crypto, but now we are targets with rage baits, guerilla marketing, buzz

Claude Code uses Bun as its runtime. If this has been merged, I expect that Bun-rust is good enough to power Anthropic's internal agents to do live testing.

Jarred had tweeted that they're using the rust version internally with Claude Code

This era is hilarious. I just wish I didn't have to rely on code written by these idiots.

> mostly a JavaScript interpreter wrapper Not accurate. Bun is a batteries-included JavaScript & CSS transpiler (parser), minifier, bundler, npm-like package manager, Jest-like test runner, as well as runtime APIs like a builtin Postgres, MySQL and Redis client. This is naturally a ton of code.

Now that Bun can leverage Rust do you think some of this code will get disaggregated? Eg, Bun could use swc crates

It wouldn't have been that hard to do that from Zig if they'd wanted to. They don't, because they want to do everything themselves so that it works exactly the way they want (except the core JS engine for which this is infeasible—though even that has custom patches). After all, there are already plenty of libraries on npm for those other parts of the stack and they do work in Bun.

You can trust them to flag some things during review that may or may not be relevant. But just like with human review and unit testing, you cannot guarantee the absence of bugs after an LLM code review. It's just another set of (virtual) eyeballs.

I trust them somewhat to flag bugs. I don't trust them to produce clean, maintainable code - even code maintainable by the LLM itself. Any sufficiently complex LLM changeset can be assumed to contain duplicated logic, method scope creep, and code changes without accompanying documentation changes that the model often will not catch no matter how many rounds of review you run. If those issues make it into a commit, th…

I find that documentation creep is wildly better in AI coded environments than human ones. You can deterministic force a documentation sync process on every PR, documentation rot has gotten way better.

I'm not sure if it's just the leading '+' or if there are other factors for phone number detection on iOS, but on mobile the line count changes are underlined and I can tap it to start a call, which, if it is because of the diff size, is something I find pretty amusing.

Maybe it's the phone number of the vibe coding police?

I just skimmed through the porting guide and based on the number of unsafe blocks, this looks like a fairly straight-forward mechanical translation.

If that is the case, why didn't they just "vibe-code" a Zig->Rust translator and a small Rust/TS/JS/whatever script to orchestrate things. You don't even need pretty printing support because rustfmt exists.

You'll save on a bunch of tokens, probably a lot of time/enegy, the process becomes auditable and (hopefully) deterministic, and if there's a mass bug in the translation, you only have to fix it in one spot.

Yeah I don’t know what’s true when reading about LLMs. Same with comments here on hacker news. So much money on the line it’s clear they would seed communities with marketing shills (and some people are just tribal). Same since they own Bun, they have every incentive to make this seem easier than it was.

This is a huge problem regarding the specifics of ai. Tech is becoming very adversarial as a worker, since marketing and technical information are blurring lines more and more.

Influencers are getting paid to promote ai for 10s of thousands of USD. This is one the reasons social media has been swamped with it lately.

It's really simple. 9 days ago this is how the migration was described: > I work on Bun and this is my branch > 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’m curious to see what a working version of this looks, what it feels like, how it performs and if/how hard it’d be to…

Stop thinking about '9 days' like it means the same thing in an era where machines can generate thousands of lines of code in a few hours. There is no way a human rewrite like this wouldn't be roughly at the same stage with a 9 day delta. In that case, some of these accusations would be reasonable to make. But that is not the case here.

Thats fine if some Claude code agent made PR and committed it. No human involved, no human drama ensued.

People here are pointing the problem because Anthropic dude claimed, it is an experiment, tests are still failing, may go nowhere.. blah..blah.

The top comment at that link points out how many of the sibling comments are delirious and emotional, kneejerk responding to the news rather than giving any sort of sober analysis. That people were overreacting with emotional meltdowns (common in AI-related threads) is perfectly compatible with the branch making enough progress to get merged.

Anyone who disagrees with me is having an emotional meltdown and obviously they're delirious AI-haters.

I'm not in a cult, you are in a cult and delusional!
