We have some great talks today at the #Community #Summit in Berlin while #SUSECON2024 is happening. Come see us in Room 3. events.opensuse.org/conferences/CS…

Dive into modern dev workflows! Learn how #Aeon & #Distrobox transform development with containers. Check out the intro & see how to adapt! #DevOps #Containers Aeon youtu.be/24F3uFMrDtE?si…

The #Linux kernel memory model is a powerful tool for developing highly concurrent code, but it also has a steep learning curve. In this #P99CONF talk, you'll learn how to get all of the benefits without the prolonged learning curve. ow.ly/sRAM50S6FTI #ScyllaDB

On openSUSE Tumbleweed, you can start writing your own CPU schedulers today: en.opensuse.org/Pluggable_CPU_… We are at "it works on my machine" stage, if you try it lemme know. See also this 30 mins intro on this custom schedulers business by yours truly media.ccc.de/v/4709-pluggab…

I was reading this brilliant article by Sergey I. on the cost of CPU ops and found a comment from King Terry there lol It works well as a mental model imo and illustrates the differences in orders of magnitude from L1->L2->L3->RAM reads->syscalls very nicely.

Who remembers this moment in Prince of Persia (1989) where a magic mirror suddenly blocks the hero's path (and what happens afterward)? This moment was actually never planned to be in the game. My original vision was a game with lots of traps, but NO enemies... (1/10)

After re-implementing my Rust scheduler in eBPF, I ran some benchmarks from the Phoronix test suite, getting interesting results. In my experience, prototyping a scheduler in Rust and rewriting it in BPF has proven to be an effective workflow. See also: arighi.blogspot.com/2024/08/re-imp…

Week 2024/34 brought some progress to openSUSE Linux #Tumbleweed. Enjoy reading dominique.leuenberger.net/blog/2024/08/t…

I know counting GitHub stars is silly, but QEMU is at 9.9k :) Help us get to 10k! github.com/qemu/qemu/

Can AI be used to generate fully functional Linux kernel schedulers in Rust? Here some details of a silly experiment that I've done to showcase the usability of the scx_rustland_core framework and the potential of sched_ext. arighi.blogspot.com/2024/09/ai-gen…

IT HAPPENED! Sched_ext Merged For Linux 6.12 - Scheduling Policies As BPF Programs Linux 6.12 is shaping up to be a jam-packed kernel with all the new hardware support, real-time PREEMPT_RT, QR panic messages, initial Raspberry Pi 5, and now sched_ext! phoronix.com/news/Linux-6.1…

CachyOS has started supporting sched-ext very early, specially in the distribution integration as well as doing the testing for the schedulers with the community Was a really nice journey and thanks to the complete sched-ext team. Finally it happened. #Linux #sched_ext #CachyOS

One of the best C resources that I have seen. "Essential C" by Nick Parlante. It's so so underrated. Give it a go. It's free and ~45 pages.

KVM Forum has started! Live streaming is available on YouTube, for the links see kvm-forum.qemu.org

Netflix uses #eBPF to monitor & mitigate excessive CPU usage in real-time. At our free #P99CONF, #Netflix's Jose Fernandez will show how they instrument the #Linux scheduler & optimize eBPF to maintain high performance. Save your spot now! ow.ly/q4R350SFufW #ScyllaDB #DevOps
