I often make fun of @ljs for using wifi on his desktop, but the truth is something sucks with my ethernet connection from desktop to Turris, despite this being done with just a 1m factory-made patch cable. So far I've found 2 things that cause short link-downs:
- electrical blinds being moved in the nearby windows
- a close enough lightning strike

But there are other yet unkown factors too. Helpfully, @NetworkManager will always use these events to drop the vpn without restarting it automatically :( (or just waiting for the few seconds until the link recovers).

After 14yrs, the RickRoll is no more. It's finally been taken down.

Another internet meme bites the dust.

Got unreasonably excited about this new, incredibly straightforward count-distinct algorithm. The CVM algorithm is a direct replacement for HyperLogLog, it nerd-sniped Donald Knuth for weeks, *and* it can easily be taught in an entry-level CS course.

When you die, nobody will remember:

- How stressed you were
- How many hours you worked

People will remember:

hey so this is a long shot but does anyone here have experience with troubleshooting amd cards on linux? just switched from a gt 970 to a 6700xt and no matter what i do the driver won't load (i.e. as soon as it leaves vga mode, the screen goes black and the computer stops responding)

it happens on both my main linux install, as well as a fedora liveusb; doesn't happen on windows 11 so it's likely not an issue with the card

kernel logs show no errors when the amdgpu module is loaded, it just seems to be starting and then the whole computer locks up and freezes

If you're on a rolling release distro (Debian Unstable, Fedora Rawhide, openSUSE Tumbleweed, Arch Linux, Alpine Linux Edge, NixOS unstable etc.), which software tends to experience the most frequent regressions in your experience?

Quite happy with how Xen x86 maintainers/reviewers are responding to the idea of modernizing the current ASID allocator. I held the design session this morning at the regarding the same and it was quite nice to have bunch of discussions regarding the same.

The need for this has come up as part of SEV enablement work I've been doing since last few months. Slides of my talk from yesterday on the SEV project can be found here: https://sched.co/1bCFk

Excited to share bug detection tool we've been working on together with Dmitry:

https://github.com/google/gwpsan

GWPSan is a framework for low-overhead sampling-based dynamic binary instrumentation, designed for implementing various bug detectors (aka. "sanitizers") suitable for production uses.

Currently can do data-race detection, use-after-return detection, and use-of-uninits. But many more possible.

Needs Linux kernel 6.4+, and Clang 18+.

Still somewhat experimental. Use with care.
