@jarkko And for those that don't believe me, it was written about years ago: https://www.linuxfoundation.org/blog/blog/skateboarding-with-greg-kroah-hartman

@jarkko Great idea, now fixed!

I sometimes wish that I'd see more "Skilled Skateboarders" than "Skilled Board Members" at LinkedIn. World would probably be a better place if that would ever happen.

A Halloween Horror Story:

"We're in and we've broken containment - we really are living in a virtual universe"
"That near endless string of symbols is our universe"
"Yes"
"But why one giant string of noise ?"
"Is that a regexp... ?"
"Oh my god, we're living in a perl one liner!"

I'm always hyping perfetto, because it's *really really* cool! Lalit does amazing work and has been super helpful sharing his knowledge on both how to do things in perfetto and even how to add features to the code for things I found missing. So it's great to see his post about his presentation from the Tracing Summit.

One neat thing in the talk is the examples show how perfetto can also ingest and visualize perf and trace-cmd output if those tools for capturing data are more familiar then perfetto's own!

"This makes me 20% more productive!"
"So does cocaine."

@fn @ncopa Ouch, that's slow.

X is where you find the people who think they run the Internet.

Bluesky is where you find the people who think they ought to run the Internet.

Mastodon is where you find the people who actually do run the Internet, and kind of wish they didn't.

(WIth apologies to Yes, Minister)

@multisn8 Oops, yes, it is "GPD", I've now fixed the post, thanks for catching that.

So, this is what you meant, Arch Linux, right?

@sjvn @theregister Nice summary of my talk, thanks for doing that!

Greg Kroah-Hartman explains the Cyber Resilience Act for open source developers https://theregister.com/2025/09/30/cyber_reiliance_act_opinion_column/ via
@theregister & @sjvn

Greg K-H explains what #opensource developers need to know about the CRA, but why they don't need to be worried sick about it.

@ncopa You do NOT want to see the kcbench results for the riscv system I have here, it's so sad it's not even funny. So sad I haven't even powered it on in a few months, it's pretty much useless :(

@kernellogger @jeroen @axboe When using "cloud" machines, many of them have horribly slow storage paths, so yes, it does affect kernel build times on those systems. Now if the "cache" really does anything for that type of storage or not, I do not know, but it can't hurt. Just like running sync 3 times before rebooting :)

It took me two days, off and on, to read this. I consider it a clear-sighted and well-researched analysis of the coming collapse of the mega-scale AI companies, and OpenAI in particular.

Ed Zitron's been loud and consistent in his reporting for a long time.

Benchmarking the different machines in my office with the wonderful kcbench: http://www.kroah.com/log/blog/2025/10/01/the-only-benchmark-that-matters-is.../

#kr2025 is already over! A huge thank you…

... to all the speakers who made this edition such a success,

to our godfather @paulmckrcu who did an incredible job putting together and keeping track of the agenda,

to Jean-Christophe for making the livestream possible and running the sound and video so flawlessly,

to @Aissen for the amazing live blog,

to Erwan for his spot-on mic throws,

to Frank for joining us on this third day and adding that little touch of craziness to the conference,

@msw @jacques @bagder Are people ignoring the fact that I do not think we have tools that can easily generate those SBOM files today?

Yes, I know about the REUSE tool from the FSFE, that's the best that we currently have but I don't think the output from it is what anyone seems to want these days. I've been publishing the output from that for years for usbutils and no one seems to even have noticed...

Am I just missing all of the wonderful tools out there that can simply generate a SBOM in a variety of needed formats from a project's tarball or normal autotools or meson build process?

Really nice talk by @gregkh at @KernelRecipes on the Cyber Resilience Act.

Really comforting, lots of facts-checking and acknowledging that the EU legal people are not against Open-Source developers. They do understand open-source and they did seek (and obtain) information from relevant technical people. It might not be perfect but I also really think it’s a step in the right direction, making manufacturers (and importers and distributors) responsible #kr2025
