The Arch Linux based CachyOS Linux distribution aims to be a "blazingly fast and customizable Linux distribution" that is aggressive with its performance optimizations. CachyOS takes to leveraging compiler optimizations like Link-Time Optimizations (LTO), the BORE scheduler, and also offering package archives compiled for x86-64-v3 and x86-64-v4 in allowing the distribution's packages to be catered toward newer Intel and AMD processors. In this article is a comparison of CachyOS packages from their main archive, the x86-64-v3 optimized packages, and then the x86-64-v4 wares that can be beneficial for modern Intel Xeon and AMD EPYC / AMD Ryzen systems.

The long in-development work for Variable Refresh Rate (VRR) support plumbed into GNOME's Mutter compositor might still make it for the GNOME 46 desktop release due out this month. It's still being treated as an experimental feature at this point but a feature freeze exception is being sought to allow its inclusion this release rather than waiting for GNOME 47 in the autumn...

Succeeding last year's Coreboot 4.22 release is now a new release... Coreboot 24.02. This open-source system firmware project is now the latest to shift to a year-month versioning system.

Nate Graham is out with his belated weekend update to highlight all of the interesting KDE development activity for the week. This week, of course, saw the release of KDE MegaRelease 6 with Plasma 6.0, KDE Gear 24.02, and KDE Frameworks 6.0 in tow. Post-launch Graham characterizes Plasma 6.0 as being in good shape and the extra QA paying off. He commented, "Hopefully this should help banish those now 16-year-old painful memories of KDE 4. It’s a new KDE now. Harder, better, faster, stronger!"..
