They do run Apple Silicon in data centers, so perhaps another custom version of Darwin + their system frameworks. It is hard to tell without some leaks :)

glhaynes commented on Ask HN: COBOL devs, how are AI coding affecting your work? · Posted by u/zkid18

AI is pretty bad at Python and Go as well. It depends a lot on who uses it though. We have a lot of non-developers who make things work with Python. A lot of it will never need a developer because it being bad doesn't matter for what it does. Some of it needs to be basically rewritten from scratch.

Over all I think it's fine.

I do love AI for writing yaml and bicep. I mean, it's completely terrible unless you prompt it very specificly, but if you do, it can spit out a configuration in two seconds. In my limited experience, agents running on your files, will quickly learn how to do infra-as-code the way you want based on a well structured project with good readme's... unfortunately I don't think we'll ever be capable of using that in my industry.

I'm not a Python programmer but I could've sworn I've repeatedly heard it said that LLMs are particularly good at writing Python.

Advice like this, and then people wonder why they’re lonely.

glhaynes · a month ago

I don't know… people were lonely before LLMs. And, they're right, this is a question one could easily paste into a frontier model and easily get back info that's way more useful than the significant majority of blog posts or replies would give! shrug But also I'd still like to hear what fooker has to say!

I had to implement system calls in xv6.

You can look up which top tier schools use it for OS classes.

glhaynes · a month ago

At the risk of getting further off-topic: what sort of system calls did they have you implement? I’ve never done but a tiny bit of kernel hacking and that sounds like a good exercise, but I’m not sure what would be a good first syscall to add.

Hey, any thoughts on this short NYT video analysis?

I don't know if you've tried Chatgpt-5.2 but I find codex much better for Rust mostly due to the underlying model. You have to do planning and provide context, but 80%+ of the time it's a oneshot for small-to-medium size features in an existing codebase that's fairly complex. I honestly have to say that it's a better programmer than I am, it's just not anywhere near as good a software developer for all of the higher and lower level concerns that are the other 50% of the job.

If you have any opensource examples of your codebase, prompt, and/or output, I would happily learn from it / give advice. I think we're all still figuring it out.

Also this SIMD translation wasn't just a single function - it was multiple functions across a whole region of the codebase dealing with video and frame capture, so pretty substantial.

That's a good way to say it, I totally identify.

It does feel very brute force though, doesn't it? It feels like we should be able to guess the manifold that has all the important stuff for each question. But it doesn't seem like we can currently! Why not?

I’ll take the opposite side! This seems completely unprecedented. I have nearly no faith in any estimates of even the relatively near-term future.

still makes sense to prevent overruns right? IE /home/ cant drop the whole system just cause you torrented too many debian ISOs and blew out your disk.

same for /var/ or wherever you store your DB tables like MySQL.

glhaynes · a month ago

Ah, yeah, that makes sense, thanks. My experience as "sysadmin" has largely been from the standpoint of personal systems for which that has mostly not been a big concern for me.

On a similar note: just the other day I was thinking about how the Unixy systems I used 20+ years ago used to nudge/push you toward creating several actual partitions during installation. Maybe /, /usr, swap… maybe one or two more? IIRC, I think some of the BSDs, at least, maybe still do? Always seemed weird and suboptimal to me for most installations, but I remember being told by graybeards at the time that it was the Right Way.
