Timing really is everything for making the frontpage, I posted this last night and it got no traction.
One strategy is to wait for US to wake up, then post, during their morning.
Other strategy is to post the same thing periodically until there is response.
Clarification added later : One of my key interests at the moment is finding ways to run untrusted code from users (or generated by LLMs) in a robust sandbox from a Python application. MicroQuickJS looked like a very strong contender on that front, so I fired up Claude Code to try that out and build some prototypes. I had Claude Code for web figure out how to run this in a bunch of different ways this morning - I hav…
Down to -4. Is this generic LLM-dislike, or a reaction to perceived over-self-promotion, or something else? No matter how much you hate LLM stuff I think it's useful to know that there's a working proof of concept of this library compiled to WASM and working as a Python library. I didn't plan to share this on HN but then MicroQuickJS showed up on the homepage so I figured people might find it useful. (If I hadn't dis…
If there were a software engineering hall of fame, I nominate Fabrice.
rare occasion where he gained a legendary status based purely on his work, I dont think I ever saw even a written interview with the guy

https://www.mo4tech.com/fabrice-bellard-one-man-is-worth-a-t... (few quotes, more like a profile piece)
He keeps a low profile and let his work speak for itself.
He really is brilliant.
Fabrice Bellard is widely considered one of the most productive and versatile programmers alive: - FFmpeg: https://bellard.org - QEMU: https://bellard.org/qemu/ - JSLinux: https://bellard.org/jslinux/ - TCC: https://bellard.org/tcc/ - QuickJS: https://bellard.org/quickjs/ Legendary.
For all the praise he gets here, few seem interested in his methods: writing complete programs, based on robust computer science, with minimal dependencies and tooling.
That was a sort of defining moment in my personal coding; a lot of my websites and apps are now single file source wherever possible/practical.
I'm not an embedded systems guy (besides using esp32 boards) so this might be a dumb question but does something like this open up the possibility of programming an esp32/arduino board with Javascript, like Micro/Circuit Python?
I wish for this new year we reboot the Web with a super light standard and accompanying ecosystem with - A small and efficient JS subset, HTML, CSS - A family of very simple browsers that do just that - A new Web that adheres to the above That would make my year.

The embedded use case is obvious, but it'd also be excellent for things like documentation — with such a browser you could probably have a dozen+ doc pages open with resource usage below that of a single regular browser tab. Perfect for things that you have sitting open for long periods of time.

I think many subscribe to this philosophy: https://distantprovince.by/posts/its-rude-to-show-ai-output-... Your github research/ links are an interesting case of this. On one hand, late AI adopters may appreciate your example prompts and outputs. But it feels like trivially reproducible noise to expert LLM users, especially if they are unaware of your reputation for substantive work. The HN AI pushback then drowns ou…
My simonw/research GitHub repo is deliberately separate from everything else I do because it's entirely AI-generated. I wrote about that here: https://simonwillison.net/2025/Nov/6/async-code-research/#th...
This particular case is a very solid use-case for that approach though. There are a ton of important questions to answer: can it run in WebAssembly? What's the difference to regular JavaScript? Is it safe to use as a sandbox against attacks like the regex thing?
Those questions can be answered by having Claude Code crunch along, produce and execute a couple of dozen files of code and report back on the results.
I think the knee-jerk reaction pushing back against this is understandable. I'd encourage people not to miss out on the substance.
I easily managed to build quickJS to WebAssembly for running in https://exaequOS.com . So I need to do the same for MicroQuickJS !

It is because you keep over promoting AI almost every day of the week in the HN comments. In this particular case AI has nothing to do with Fabrice Bellard. We can have something different on HN like what Fabrice Bellard is up to. You can continue AI posting as normal in the coming days.
Forget about the AI bit. Do you think it's interesting that MicroQuickJS can be used from Python via FFI or as a compiled module, and can also be compiled to WebAssembly and called from Node.js and Deno and from Pyodide running in a browser? ... and that it provides a useful sandbox in that you can robustly limit both the memory and time allowed, including limiting expensive regular expression evaluation? I included…
I read this post of yours https://simonwillison.net/2025/Dec/18/code-proven-to-work/ and although there is a point that can be made that what you are doing isn't a job and I myself create prototypes of code using AI, long term (in my opinion) what really matters are the maintainance and claim (like your article says in a way, that I can pin point a person whose responsible for code to work)
If I find any bug right now, I wouldn't blame it on you but AI and I have varying amount of trust on it
My opinion on the matter is that for prototyping AI can be considered good use but long term it definitely isn't and I am sure that you share a similar viewpoint.
I think that AI is so contrasting that there stops existing any nuance. Read my recent comment (although warning, its long) (https://news.ycombinator.com/item?id=46359684)
Perhaps you can build a blog post about the nuance of AI? I imagine that a lot of people might share a similar aspect of AI policy where its okay to tinker with it. I am part of the new generation and trust be told I don't think that there becomes much incentives long term unless someone realizes things of not using AI because using AI just feels so lucrative for especially the youngsters.
I am 17 years old and I am going to go into a decent college with (might I add immense competition to begin with) when I have passion about such topics but only to get dissuaded because the benchmark of solving assignments etc. are done by AI and the signal ratio of universities themselves are reducing but they haven't reduced to the point that they are irrelevant but rather that you need to have a university to try to get a job but companies have either freezed hiring which some point out with LLM's
If you ask me, Long term to me it feels like more people might associate themselves with hobbyist computing and even using AI (to be honest sort of like pewdiepie) without being in the industry.
I am not sure what the future holds for me (or for any of us as a matter of fact) but I guess the point I am trying to state is that there is nuance to the discussion from both sides
Have a nice day!
