Building a Debugger is now officially released!

It guides you through writing a whole native x64 debugger from scratch, dispelling all the magic and teaching you a ton about operating systems as it goes.

Even if you don't care about writing a debugger, you can read it to your cat.

The Portland Linux Kernel meetup is tomorrow, June 11th, at the Lucky Labrador Beer Hall on NW Quimby https://www.meetup.com/portland-linux-kernel-meetup/events/308186013/ #portland #pdx #linuxkernel #kernel #linux

One week in as a computer architect and I can already fit a line to a single data point!

Internet Archive is looking for engineering managers with a rare set of experiences, and we could use your help.

Do you know someone with extensive experience using PHP as a systems language? Someone who has gardened a petabyte-scale system under high load? Is this person a player/coach engineering manager who enjoys helping other people succeed?

If you do know someone like this, or someone close, I would love to talk to them.

Apply at this link and drop me a line:

@axboe @dagmcr ya, I was principled for a long time but I'm sort of just tired these days...

That said, it's so bad it doesn't even matter ;)

We'd love your feedback.

I guess I haven't been paying enough attention, but Intel's APX is a really big update to their ISA:
- 32 GP registers
- setting flags is optional in many cases
- instructions take 3 operands instead of 2

@axboe @dagmcr I'm trying to run OSX for the first time and it's really surprising how horrible it is...

@maggiejk Hopefully it's not in Virginia... https://www.theguardian.com/us-news/2025/jun/04/virginia-crosswalk-vandalism-charge-charlottesville

This is hot.

@ljs @josefbacik I don't use lei, I use l2md which was written by Daniel Borkmann and I find it a lot simpler for what I need to do and it is git-based which is even nicer.

I used lei some time ago for a while but it was just too complex for what I wanted.

But I still have a personal inbox I need to use which doesn' t have anything to do with mailing lists per se.

What makes LLMs work isn't deep neural networks or attention mechanisms or vector databases or anything like that.

What makes LLMs work is our tendency to see faces on toast.

"Congratulations on having your first Pull Request (PR) merged into the LLVM Project!"

It's over for me

I can't believe we replaced blogs and RSS with people emailing their posts to you. just a really obviously stupid step backwards

Signal have rolled out an update to all users that stops Microsoft Recall from capturing Signal conversations.

I’ve tested this and it works. Brilliant work by the @signalapp team. 💪

They call on Microsoft to build better, as there was no standardised way as an app developer to do this. Because Signal is open source, now app developers have a template to protect their users from Windows.

I got it, thanks ;)

Is anyone else at Facebook? I can't figure out how to let my VM talk to kernel.org, just copying the GitHub lines didn't work and I can't figure out how to find anything on these internal tools...
