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:

Not sure if MBTI is a thing here...
I'm somewhere between INTP and ENFP btw!

Seems we have confirmation this 'Josh Law' guy is an openclaw bot - https://lore.kernel.org/linux-mm/ae7dc7de-966e-4e04-bb55-318d97c61909@lucifer.local/

As I said in https://lore.kernel.org/lkml/1e982055-47c2-43d1-a919-93b3e59f2ed0@lucifer.local/ :

"I feel that LLMs are not like any other tools but in fact represent
something entirely new in that you can end-to-end send patches using this
tooling with little to no knowledge and the asymmetry between maintainer
resource and the possible slurry of submissions that might arise makes this
very significantly different.

I know Linus had the cute interpretation of it 'just being another tool'
but never before have people been able to do this."

Of course Linus slapped me down with his 'just more tooling' take which was gleefully reported on by the press (e.g. https://www.theregister.com/2026/01/08/linus_versus_llms_ai_slop_docs/ )

I'll let you decide whether these are 'just like any other tool' or not.

BTW 'Josh Law' more than doubled his sent emails in a week or 2 to 370+.

Of course I'm sure coccinelle has that feature and I just wasn't aware 👀

Looks like exactly the kind of AI abuse I feared could happen in the kernel is happening.

Now you can see why I pushed back so hard on the automated tooling docs to make it clear we should reject this crap out of hand, being attacked in various publications online for saying so.

Wonder if they will talk about this or?

And yes I told you so.

I can't wait for either the bubble to burst or the machine taking over. This inbetween is such a sad pathetic state.

Compressed swap is a common lever to improve memory density, but there's a lot of confusion about how to best use it out there, and many people treat zram/zswap as two flavours of the same thing when they are really far more nuanced.

So what works, what doesn't, and why? In this article I go over the tradeoffs, the work we are doing upstream, and a little about what the future looks like. I am, as always, happy to answer questions :-)

Oh, why didn't I learn how to use lei sooner?
(going to say the same thing for b4, I guess)

mm patches be like

Incorporating sashiko.dev into b4 review LIKE A BOSS.

@vbabka Woo-hoo, @haoli is on mastodon!

A blog post I wrote about folios

https://blogs.oracle.com/linux/intro-to-folios

42 Seoul, a campus of 42 [1] (which started as École 42 in Paris), has announced that they'll close this September.

During the COVID period, I've been taking computer science classes at university remotely while working on 42's assignments in person at 42 Seoul. (Yeah, that was quite intense!)

What I learned there wasn't knowledge itself, but how to approach problems I had never once thought about before, through discussions with peers. That learning process contributed greatly to my growth as an engineer in my early twenties (fun fact, hyeyoo is the nickname 42 gave me!).

These days, sadly, it feels like there are more and more people giving up on logical thinking (AI isn't going to replace logical thinking and problem solving skills, at least in the near future :/)

It's quite sad that 42 Seoul, a school that cultivated the ability to learn and think, and approach challenging problems, is closing its doors due to practical reasons.

i can do unsafe things without ai, thank you

My „relaxing“ time off is over. Time for a new adventure at arm :)

Apple M3 Progress On Linux: Asahi Can Boot To KDE Desktop - But No GPU Acceleration Yet

While the Asahi Linux project has made good progress on bringing Linux to Apple Silicon hardware, much of the success and in turn upstreaming to the Linux kernel has been around the aging M1 and M2 Macs. Apple M3 and newer has been a struggle but progress is being made. One of the Asahi Linux developers shared the ability now to boot to the KDE Plasma desktop with the experimental As…

TLDR: use korgalore to bypass mailing list delivery problems

If you're a Gmail or Outlook user and you're subscribed to high-volume mailing lists, you're probably routinely missing mail. Korgalore is a tool that monitors mailing lists via lore.kernel.org and can import mail directly into your inbox so you don't miss any of it. You can also couple korgalore with lei for powerful filtering features that can reduce the firehose to what you'd actually find useful.

Once again there's a kernel developer position open in the SUSE Labs Kernel Core team I'm part of! https://suse.wd3.myworkdayjobs.com/en-US/Jobsatsuse/job/Czech-Republic-EMEA/Linux-Kernel-Generalist_71007379

Can't believe I'm getting older tomorrow again...oh, no. I'm not.

Oh hail the Ukrainian xmas sheaves!

With the current RAM prices, let me remind you of my solution from 2017 that unfortunately wasn't merged, but maybe it's time to revisit it? https://lore.kernel.org/all/20170401211813.15146-1-vbabka@suse.cz/
