Protect your privacy and freedom. GNU/Linux lover. Let's burn everything down. I am doing networking stuff around linux kernel. No AI.

Become who you are!

I am supposed to trust that this guy is just a student. Although a student capable of contributing to completely different subsystems and finding subtle bugs (or fake ones).

Coincidentally, if I feed the code to a LLM it suggest the same "Modernization and Cleanup".

I am so tired, I never expected that I would be playing "who is telling lies" in a mailing list.

People keep assuring me that LLMs writing code is a revolution, that as long as we maintain sound engineering practices and tight code review they're actually extruding code fit for purpose in a fraction of the time it would take a human.

And every damned time, every damned time any of that code surfaces, like Anthropic's flagship offering just did, somehow it's exactly the pile of steaming technical debt and fifteen year old Stack Overflow snippets we were assured your careful oversight made sure it isn't.

Can someone please explain this to me? Is everyone but you simply prompting it wrong?

It's a good thing programmers aren't susceptible to hubris in any way, or this would have been so much worse.

@ffmancera looked it up on wikipedia and i think i understand it's basically this for ethernet
Like my patches are far from being perfect and indeed I mess up a lot. But this patch just doesnt make any sense..
I hate to push back this much but I just spent an hour reading IEC 62439-3 to understand if HSR/PRP supervision frames might have duplicated TLVs.

Age verification clearly doesn't belong into #systemd. We should have never merged this. Instead this should be incrementally added to the kernel itself. I'm doing my part:

[PATCH] vfs: require verified birth date for file creation - Christian Brauner

This time I am the bad guy in the room, this is a situation quite similar to Josh Law one.

[PATCH net-next v4 0/2] net: hsr: strict supervision TLV validation

The best series I have seen in Linux kernel this year:

Bye, bye LEGACY_IP!

[PATCH 0/6] Deprecate Legacy IP - David Woodhouse

Btw, the patch series the guy is reviewing it is probably AI generated too. What a world.

In other news, the AI I was talking to some days ago decided now to review a series of rtl8723bs in linux-staging.

It just generated a huge wall of text not following the LKML formatting of course.

By the way, this is clearly AI generated. Wondering if I should reach out to Gregk or someone else. It is hard to do given I am not an expert on rtl8723bs or any wireless device really.
