• The August 17 outage, and the work ahead

  Here's the most recent one as of this comment: https://github.com/oven-sh/bun/commit/d4de65e9a43224a14591ad...

  The code change makes no sense and should do nothing. The commit message described a very deep investigation into garbage collection on the C++ side. Some object is being kept alive when the test requires it to be collected, and changing the code in this way allegedly prevents that. But wouldn't you think there would be a better way to ensure an object gets collected, like setting the variable to null?

  The comments in the code don't make a lot of sense either. Something so obscure and brittle has to be explained extremely clearly.

  While the issue might be real, this commit is so far away from the locus of normal that it's sending red alert. And this is the 1 out of 1 robobun commit that I looked at.

• Bun 1.4

  "We receive a lot of contributions from the community, and we'd like to thank everyone who fixed a bug or contributed a feature in this release."

  I filled a bug https://github.com/oven-sh/bun/issues/34588 and a PR but my name is not on the blog :(

• Bun 1.4 Released
• Bun 1.4 Rust rewrite is not looking good

  > What are you talking about?

  I think GP was pointing out how bun's release cadence stalled and the project is going nowhere at the moment.

  https://github.com/oven-sh/bun/releases

  The project was pretty healthy up to 1.13.14, but since may they stopped shipping anything.

  That's quite odd for a project that just went through a major rewrite and is lauded as being developed primarily by LLM coding assistants.

  Personally I expected the release cadence was going to go through the roof, but instead it flat lined.

  > could you link me to the release / tag on github

• Claude Code uses Bun written in Rust now

  > In the rewrite blog post

  They can't mention what they don't know. And that's the exact reason I'm against this: doing a port without being able to tell what is correct is asking for a disaster, obviously.

  I've checked their posts and blogs for a few times, and I'm quite sure they don't know any of these.

  > the 1.4 version has not been released yet

  Let's hope the repeated delays (it was scheduled for last week) are not for quality issues, otherwise I'll only be half correct. It appears that all the new undefined behaviors are not stopping them.

  > get rid of the unsafe block

  Would be possible if they are not disregarding everything else going for numbers. E.g. they are actively increasing the unsafe surface by [rewriting some code in SIMD C++](https://github.com/oven-sh/bun/pull/33032). As if no Rust solutions already exist.

  > Still easier than the Zig version

  Well, this is true but only realizable if they know how to deal with the new problems emerging during the process. My current conclusion is that they don't.

  > ideological

  For me it's methodological as explained above.

• (bun GitHub repository) AI slop #33864
• Zig Creator Calls Spade a Spade, Anthropic Blows Smoke

  There are a lot of posts going on, but let me just post this link to a specific file of the bun zig code base so you can make your own impression:

  https://github.com/oven-sh/bun/blob/bun-v1.1.42/src/bundler/...

  My take is they vibe coded too close to the sun
