Java can run anywhere too
Not in the browser, and no – webassembly doesn't count, otherwise you can say the same about Go and others.
I remember a time ...

Re: Anthropic acquires Bun
#592A lot of people seem confused about this acquisition because they think of Bun as a node.js compatible bundler / runtime and just compare it to Deno / npm. But I think its a really smart move if you think of where Bun has been pushing into lately which is a kind of cloud-native self contained runtime (S3 API, SQL, streaming, etc). For an agent like Claude Code this trajectory is really interesting as you are creating…
As a commandline end user who prefers to retreive data from the www as text-only, I see deno and bun as potential replacements (for me, not necessarily for anyone else) for the so-called "modern" browser in those rare cases where I need to interpret Javascript^1 At present the browser monstrosity is used to (automatically, indiscriminantly) download into memory and run Javascripts from around the web. At least with a…
Is this something I’d have to own a tv to understand?
Re: Anthropic acquires Bun
#593Genuine question: why js? Why not something like c#: native, fast, crossplatform, strongly-typed, great tooling, supports both scripting (ie single file-based) and compiled to a binary with no dependency whatsoever (nativeAOT), great errors and error stacks, list goes on. All great for AI to recover during its iterations of generating something useful. Genuinely perplexed.
Same reason AIs also use Python and DBMSes offer JS or Py UDFs easily, interpreted languages take no build time and are more portable. JS is also very popular.
Might also be a context window thing. Idk how much boilerplate C# has, but others like Java spam it.

IIRC bun zig code base has a lot of fine optimization too. I think the lead did a conference explaining his work. Or maybe i'm confused.

oh thanks yes, i couldn't find it, i was already lost thinking it was a conference by andrew kelley .. thanks a lot

When you say runtime sandboxing, are you referring to JavaScript agents? I haven't worked all that much with JavaScript execution environments outside of the browser so I'm not sure about what sandboxing mechanics are available.
https://nodejs.org/api/vm.html Bun claims this feature is for running untrusted code ( https://bun.com/reference/node/vm ), while Node says "The node:vm module is not a security mechanism. Do not use it to run untrusted code." I'm not sure whom to believe.
It's interesting to see the difference in how both treat the module. It feels similar to a realm which makes me lean by default to not trusting it for untrusted code execution.
It looks like Bun also supports Shadow Realms which from my understanding was more intended for sandboxing (although I have no idea how resources are shared between a host environment and Shadow Realms, and how that might potentially differ from the node VM module).

#597Quote from the CEO of Anthropic in March 2025: "I think we'll be there in three to six months where AI is writing 90% of the code and then in 12 months we may be in a world where AI is writing essentially all of the code"
Given the horrible stability of Windows this year, it seems like Microsoft went all in on that

It's widespread and good enough. The language just doesn't matter that much in most cases
This is one of those, "in theory, there's no difference between theory and practice. In practice, there is" issues. In their, quality software can be written in any programming language. In practice, folks who use Python or JavaScript as their application programming language start from a position of just not carrying very much about correctness or performance. Folks who use languages like Java or C#, do. And you can…
That's not a fair comparison. In your example, you're talking about the average of developers in a language. In this situation, it's specific developers choosing between languages. Having the developers you already have choose language A or B makes no difference to their code quality (assuming they're proficient with both)

If I was to pick a language, I'd pick the one all developers agree is the best.
Ahahahahhahahahahhahahahaahaha. Please tell me this is tongue-in-cheek and just more subtle than I give HN credit for. Please.
Not all devs, not even most, but I certainly think this

#600Wondering to what degree this was done to support Anthropic’s web crawler. Would assume that having a whole JS runtime rather than just a HTTP client could be rather useful. Just hypothesising here, no clue what they use for their crawler.
