POSIX

To removing the need for platform teams to manually provision or tear down storage volumes.

Key technical features include per workspace access isolation for security boundaries, sub-second attach and detach times to support suspending and resuming idle sandboxes, and native read/write many support with POSIX, uh, file locking for multi-agent collaboration on shared file trees.

Pricing follows a pay-per-use model based on actual storage consumed rather than pre-allocated capacity, with automatic lifecycle tiering to shift idle data to lower cost storage tiers.

Yeah, I mean, this, this is a problem I haven't run into yet, but I know it's in my future, like trying to figure out how to provide these execution runtime environments in a secure and safe manner and, and at scale.

then have clear explicit fault models and make make your gates to the real world buggy and unreliable just say look i i assume that if i write something hey that just didn't even do it end-to-end principle i'll check for that in my logical code and i can repair and then that you you simulate then it's actually beautiful very reliable um And so that's the way to do DST.

Some people make the mistake, they do DST even of POSIX, like reading and writing files and directories.

Don't do that.

Don't do that because you don't need it.

You don't need to check POSIX.

Yeah, it's a nightmare.

And now you've got a massive storage interface that's going to explode the machine.

So again, it's this 90% logical, 10% physical, and then these ones you really fuzz a lot, and this is you focus on the global protocol.

don't think the whole lot has been...

So if you look at the POSIX standardization Wikipedia page, as well as AIX, there's also spins of Red Hat, which have been certified, and there have been a few.

So it's definitely been certified as POSIX compliant.

Certified as Unix is a different thing, but it's definitely POSIX compliant.

That's a distribution that has been certified, not an actual...

That's an

The fundamental issue is architectural.

OpenAI Triton was conceived and built for POSIX-compliant environments.

It expects a Linux-like threading and process management system.

Historically, compiling these custom kernels on Windows required incredibly complex C++ build tools or forcing users to run inside the Windows subsystem for Linux, WSL2.

I already did this on my old i3 Arch, quote, 'by the way' machine." And so he's got a, a, a bash script.

Um, I'm assuming he meant to write that as a shell script, POSIX anyway.

While true, and then he's running the FEH, that, that, uh, uh, program that lets you set wallpapers.

Now, the not anymore Rust Ox WM has randomly started changing backgrounds.

Which few people use.

It didn't become part of the POSIX standard.

And it has an interesting relationship to the more commonly used BC.

I might be worth making this a subject of a future Unix QDO.

We'll think about how I might rewrite it to bring that in.

Good point about looking in different places.

It recently occurred to me that I should be more open to utilities outside POSIX.

I have identified a few that came from BSD and gained widespread use despite never being standardized, which might be interesting.

Me too.

Also, enhanced compliance with POSIX 2024 and C23 programming interface standards.

Wait, hold on.

Compliance with standards? That's crazy.

His tag is, you know, at Virtually Fun.

And he's always doing cool things like the POSIX subsystem and the NT subsystem and the OS2 subsystem and getting old software to run and getting pinball to run on a MIPS and all kinds of crazy stuff.

So if you're into that era of stuff, he's a good person to follow.

And as for X, I know it's not everybody's cup of tea, but I'm trying to stay kind of neutral.

[laughs]

They- they- they're happy with POSIX compliance.

Yeah.

Yeah.
