Unfortunately I found the performance to be enough of an issue that I did not look much further into it.
This thing is really inescapable those days.
I should have replied there instead, my mistake.
I'm excited about them and I think discussion on how to combine two exciting technologies are exactly what I'd like to see here.
You can't just roll in to a random post to tell people about your revolutionary new AI agent for the 50th time this week and expect them not to be at least mildly annoyed.
The entire thing is just quotes and a retelling of events. The closest thing to a "take" I could find is this:
> I have no idea how this one is going to play out. I’m personally leaning towards the idea that the rewrite is legitimate, but the arguments on both sides of this are entirely credible.
Which effectively says nothing. It doesn't add anything the discussion around the topic, informed or not, and the post doesn't seem to serve any purpose other than existing as an excuse to be linked to and siphon away attention from the original discussion (I wonder if the sponsor banner at the top of the blog could have something to do with that...?)
This seems to be a pattern, at least in recent times. Here's another egregious example: https://simonwillison.net/2026/Feb/21/claws/
Literally just a quote from his fellow member of the "never stops talking about AI" club, Karpathy. No substance, no elaboration, just something someone else said or did pasted on his blog followed by a short agreement. Again, doesn't add anything or serve any real purpose, but was for some reason submitted to HN instead of the original tweet[1]. The original link was eventually submitted a whole 9 hours later[2] and superseded it, but of course, it still had to contain a link to Simon's blog in the body, too.
Apptron uses v86 because its fast. Would love it for somebody to add 64-bit support to v86. However, Apptron is not tied to v86. We could add Bochs like c2w or even JSLinux for 64-bit, I just don't think it will be fast enough to be useful for most.
Apptron is built on Wanix, which is sort of like a Plan9-inspired ... micro hypervisor? Looking forward to a future where it ties different environments/OS's together. https://www.youtube.com/watch?v=kGBeT8lwbo0
Besides, prompt injection or simpler exploits should be addressed first than making a virtual computer in a browser and if you are simulating a whole computer you have a huge performance hit as another trade off.
On the other hand using the browser sandbox that also offers a UI / UX that the foundation models have in their apps would ease their own development time and be an easy win for them.

tldr; devcontainers let you completely containerize your development environment. You can run them on Linux natively, or you can run them on rented computers (there are some providers, such as GitHub Codespaces) or you can also run them in a VM (which is what you will be stuck with on a Mac anyways - but reportedly performance is still great).
All CLI dev tools (including things like Neovim) work out of the box, but also many/most GUI IDEs support working with devcontainers (in this case, the GUI is usually not containerized, or at least does not live in the same container. Although on Linux you can do that also with Flatpak. And for instance GitHub Codespaces runs a VsCode fully in the browser for you which is another way to sandbox it on both ends).
Do you know if there's a cli or something that would make this easier? The GitHub org seems to be more focused on the spec.
Please? I'm begging here.
Even in this thread alone https://news.ycombinator.com/item?id=47314929 some commenters here are clearly annoyed with the way AI is being shoved in each place where they do not want it.
I don't care, but I can see why many here are getting tired of it.
