Linus Torvalds uses Claude Code for a major Linux kernel performance improvement
The Linux creator is using Anthropic's Claude Code to help draft a test program and commit message for a new kernel optimization.
What to know
- Linus Torvalds is using Anthropic's Claude Code to work on a substantial performance improvement to the Linux kernel.
- Claude is also drafting an associated test program and the commit message for the change.
- Torvalds has previously used AI for kernel debugging and separately experimented with Google's Antigravity for 'vibe coding' outside the kernel tree.

Mastodon user reacts sarcastically to the news
A Mastodon user shares the Phoronix story with a sarcastic comment about the state of the world.
“Die dümmste Timeline.”

Reading the [patch message](https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=noref-filemap-read-with-llm&id=4c0f3697118eb3a708ea79175f7f07c43339bfab) is honestly disheartening. I think everyone can agree that AI has some utility as a code reviewer at least. Whether to use it to generate code is controversial but…

i’m anti ai but i also acknowledge that there are uses for ai. unfortunately, the term has become an umbrella for the entire gamut of talking points about it, and i think the term “automation” has fallen under the umbrella. there’s nothing wrong with automation. outsourcing drudge work is what technology has been doing for us for all of history…

Phoronix reports Torvalds using Claude Code on kernel perf work
Michael Larabel reports that Linus Torvalds, who has previously used AI for kernel debugging and done vibe coding with Google's Antigravity outside the kernel tree, is now using Claude Code to work on new Linux kernel features.
“Linux creator Linus Torvalds has been known to use AI to help with kernel debugging and outside of the kernel tree has also done some vibe coding with Google's Antigravity.”

My college studies improved the moment I discovered books that teach people how to study and how to learn. I found the first book accidentally. It was resting on a bookshelf in one of my old colleges. It looked interesting. A 'Whack on the Side of the Head', the version that came with the pack of thought cards. People are not taught how to learn…

There's going to be some real issues when people realize how much of cybersecurity isn't being treated as "serious work" by vendors right now. It's really bonkers.

I'd like to take this moment to just say how batshit crazy treating productivity like a fucking video game is. Like... black mirror distopia levels of batshit crazy

You arent paid by project. But the company is. The company that is outcompeting others by being faster, and thus securing more revenue is more likely to be able to increase your pay to retain you. As an aside, what kind of stuff do you work on? Im in a service based Saas, highly customised per customer, and so AI allows us to lower the budget…

I’ve wondered this as well. Even the most hardcore detractors at my company use it now, and not because they are forced to. Around Fable and GPT 5.6 Sol timeframe, things shifted and they started getting results that didnt need to be completely rewritten. Probably coincided with all the work we put into making our repos more agent-friendly…

Being on these subs are do tiring, every people telling you you should give up everything you like and surrender to stop thinking and become a prompter. Feels like people taking revenge against devs for living the good life until now.

Why are you so confident in that, if you're a non-native English speaker? I'm a native English speaker, and I have also written lots of technical blog posts for over a decade, and I see Claude slop all over the place. If what you said were true, then I would have never have seen Claude slop, and that's obviously not true. If you genuinely haven't…

I once watched a presentation on a piece of research that shows LLMs change the meaning of a text ever so slightly when you feed text through it (because of synonyms, adding/removing repetitions, etc.). The particular graph I remember is some kind of point cloud, where two clusters can be seen. One of human written text, and another of their LLM…

I wish there was a way to better classify this awful style of pose that all LLMs generate. I'm actually writing a paper at the moment on the topic of AI slop. While I've had incredibly surprising success with regexes and even a simple naive Bayes classifier, as a human I can smell this style of prose almost instantly, yet it seems hard to teach a…
-
It's objectively controversial, people have sharp disagreements about not only whether but how to use LLMs and there's a wide range of opinions. But also, read the room. "Half the commenters here are flat earthers" is not really conducive to discussion.

> but the software quality of some projects is improving I'd be very interested to know *which* software project quality has improved over the last year. Almost every software I am using had dropped to insane low levels. I am using an M5 with the latest macOS and the amount of glitches/bugs/defects is beyond shameful.
-
Yeah. If I had to pick literally one single human to read through 100,000 lines of bullshit PRs and firmly reject the bad ones, well, Linus has spent the majority of his "development" time doing that for 30 years now. And he's not especially shy about rejecting bad code. (By which I mean mainstream media was starting to write about his rejections…

> It doesn't matter because there's no way to avoid LLM-generated code There's no way to avoid a lot of things, but that doesn't justify them.

Once you start spending your time talking to AI, you start to lose what makes you unique. You stop generating uniqueness and start consuming sameness. People are natural mimics and empaths. You can't spend your time conversing with a statistical model and not be cognitively affected by it.

Yesterday I got an email responsibly disclosing two vulnerabilities in Lobsters, found with LLMs. They've been there 8 years. I have lost track of how many years-old vulns and bugs that LLMs have been identified in our codebase in the last two years. LLMs are making [Linus's Law](https://en.wikipedia.org/wiki/Linus%27s_law) true. Feels very much…

Just because it's prevalent doesn't mean we should give up. The resistance is growing and will keep growing. It's still quite early days for the resistance and we are gaining ground.

> I personally am not happy about this, the last place I want AI to touch is my Linux. Is that for ethical reasons or code quality reasons or both? If it's the former then fair enough. If it's the latter, one could make a credible case that Linus Torvalds is the most experienced code reviewer in the world.
-
Some people are upset about prevalent LLM usage. "It doesn't matter because there's no way to avoid LLM-generated code." feels a bit dismissive/inconsiderate?
