Very happy to see PostmarketOS take an uncompromising stance and also providing justification for it.

Feels pretty Luddite to me.

I remember when people were crying about how much power a google search uses. This is the same thing all over again and it is as pointless now as it was back then.

No, it's entirely justified when quality of code matters. They don't want a thousand gallons of unreviewable slop. They want a reasonable amount of code that can be sensibility reviewed.

You say "uncompromising stance" with "justification", I say stubborn prejudice. They simply state the same weak, nonsensical complaints that apply to many other technologies that they undoubtedly don't have issues with and are happy with the use of.

> bans use of generative AI

that ship has sailed with codex 5.3 in 90% SWE jobs, unfortunately. I expect the next 9% won't survive the following 12 months and the last 1% is done within 5 years.

it isn't even about principles - projects not using gen AI will become basically irrelevant, the pace of gen AI allowed competitors will be too great.

Alright, let's see Codex 5.3 create a competitor to postmarketOS (without just copying the homework of other devs). If you believe in the technology so much, put it to the test, see what it can really do.

I do not understand why Lineage insists on waiting for eBPF back ports when PostmarketOS has a far newer kernel running on the same hardware.

Core Android functionality relies on eBPF in a way that PostmarketOS does not. PostmarketOS is much more of a linux distro than Android is. They are not very comparable.

AOSP patched kernels still include some features that are not in the mainline version. The LineageOS folks are working on support for mainline kernels, but AIUI it's not there yet.

> Submitting contributions fully or in part created by generative AI tools to postmarketOS.

So, autocomplete done by deterministic algorithms in IDEs are okay but autocomplete done by LLM algorithms - no, that's banned? Ok, surely everybody agrees with that, it's policy after all.

How it is possible to distinguish between the two in the vast majority of cases where the hand written code and autocompleted code is byte-by-byte identical?

Are we supposed to record video of us coding to show that we did type letters one by one?

> 2. Recommending generative AI tools to other community members for solving problems in the postmarketOS space.

Is searching for pieces of code considered parts of solving problems?

Then how do we distinguish between finding a a required function by grepping code or by asking LLM to search for it?

Can we ask LLM questions about postmarketOS? Like, "what is the proper way to query kernel for X given Z"?

If a community members asks this question and I already know the answer via LLM, then am I now banned from giving the correct answer?

--

Don't get me wrong. I am sick and tired of the vomit-inducing AI bullshit (as opposed to the tremendous help that LLMs provide to experienced devs).

I fail to see how a policy like this is even enforceable let alone productive and sane.

On the other hand, I absolutely see where is this policy coming from. It seems that projects are having a hard time navigating the issue and looking for ways to eliminate the insurmountable amount of incoming slop.

I think we still haven't found a right way to do it.

Because autocomplete still requires heavy user input and a SWE at the top of the decision making tree. You could argue that using Claude or Codex enables you to do the same thing, but there's no guarantee someone isn't vibecoding and then not testing adequately to ensure, firstly, that everything can be debugged, and secondly, that it fits in with the broader codebase before they try to merge or PR.

Plenty of people use Claude like an autocomplete or to bounce ideas off of, which I think is a great use case. But besides that, using a tool like that in more extreme ways is becoming increasingly normalized and probably not something you want in your codebase if you care about code quality and avoiding pointless bugs.

Every time I see a post on HN about some miracle work Claude did it's always been very underwhelming. Wow, it coded a kernel driver for out of date hardware! That doesn't do anything except turn a display on... great. Claude could probably help you write a driver in less time, but it'll only really work well, again, if you're at the top of the hierarchy of decision making and are manually reviewing code. No guarantees of that in the FOSS world because we don't have keyloggers installed on everybody's machine.

Yes and? Let's suppose your statement is 100% true, I genuinely don't see the point of these kinds of comments.

Why every time some person/group of people enact an anti-LLM policy in their project, other people feel the personal need to stress how useful LLMs are and how that project is bound to fail if they don't use it?

Postmarketos clearly exists and works, EVEN if LLMs were absolutely perfect for speeding up development ten folds, is there any absolute moral necessity to use them?

Also isn't this just moving the goalpost that LLM fanatics love to point out?

I'm pointing out that their expectation of AI-free OS is pointless.

Because AI-assisted code is most probably already present in devices they use.

And I dare say that even for PostmarktOS:

1) There's no way they can prevent AI-assisted code to reach their codebase.

2) They will most probably change this policy in the future lest other forks/projects outpace them in terms of utility and they get reduced to a carriage in a car world.

The stance is not to 'prevent AI-assisted code to reach their codebase.' It's not like AI-assisted code is literally poisonous and their codebase dies if touched.

The stance is to deter random vibe-coders trying to resume-max by submitting PRs to known open source projects. There are so many of them rn. Hopefully by making it clear (some of) them will realize doing that is just wasting their tokens.

I understand there's an avalanche of vibe slop PRs.

But to be clear their AI instance is as clear-cut as can be. Their instance IS INDEED to "prevent AI-assisted code to reach their codebase".

Probably not and why would it need such constraint?

Not even humans can do that. Documentation needs to at least be reverse-engineered and understood before implementation.

Weird stance to take.

I can understand "untested AI-genned code is bad, and thus anything that reeks of AI is going to be scrutinized" - especially given that PostmarketOS deals a lot with kernel drivers for hardware. Notoriously low error margins. But they just had to go out of their way and make it ideological rather than pragmatic.

The main reason open source projects exist at all is because of people who started them with quite often fringe ideological leanings. Just look at the GNU project.

As long as they align with the correct (i.e. yours) values, of course. When they adopt the wrong values, it's not fine.

There's still a line between values I disagree with and values that directly attack me as a person. The former is how many of us feel about some of our dependencies and most proprietary software we use, so it's clearly fine to some degree.

Exactly, you can use it for some tasks. But why "explicitly forbid generative AI".

If you use AI to make repetitive tasks less repetitive, and clean up any LLM-ness afterwards, would they notice or care?

I find blanket bans inhibitive, and reeks of fear of change, rather than a real substantive stance.

That never happens. It's actually easier to write the code from scratch and avoid LLMness altogether.

reply

They explain why in their AI policy. It's an ethical stance. Of course they wouldn't notice if there aren't clear signs of LLM-ness, but that's not the main reason why they forbid it.

The pollution caused by said revolution is currently putting humanity at a serious risk of world war and maybe even extinction so... maybe they had a point? I'm not taking a strong stance either way here, but worth thinking about the downsides from the industrial revolution, too.

The AI policy linked from the OP explains why. It's half not wanting to deal with slop, and half ethical concerns which still apply when it's used judiciously.

Same.

Having an LLM helps, especially when you're facing a new subsystem you're not familiar with, and trying to understand how things are done there. They still can't do the heavy duty driver work by themselves - but are good enough for basic guidance and boilerplate.

My reading of their AI statement says your kernel contributions are no longer welcome in PostmarketOS, and also, since you're encouraging others in their space to use such tools, you're in violation of their code of conduct.

This applies to the person you're replying to too.

I think their policy is poorly thought out, and that little good will come of it. At best, it'll cause drama in the project, and discourage useful contributions. It's a shame, since we desperately need an alternative to the phone duopoly.
