Last week I wrote about Linux patches cleaning up x86 32-bit kernel builds for x86_64 CPUs. The new iteration of those patches were sent out today, including the addition of a patch adding the CONFIG_X86_64_NATIVE Kconfig tunable for enabling "-march=native" kernel builds to cater your optimized kernel compilation for the CPU on which you are building the kernel...

Currently the Linux kernel's "perf" performance monitoring subsystem has a limit on 2,048 CPU cores for its CPU map that is set by the MAX_NR_CPUS value. But that's becoming not enough in today's high core count era that patches are looking to raise it to a 4,096 CPU core limit by default...

GNU Shepherd as a service manager for both system and user services that is used by Guix and relying on Guile Scheme has finally reached version 1.0. For those not pleased with systemd, GNU Shepherd can be used as an init system and now has finally crossed the version 1.0 milestone after 21 years of development...

It's been a few months since running any fresh Linux graphics driver comparison benchmarks. But given the imminent availability of the first Intel Arc Battlemage graphics cards, I have been carrying out some fresh Linux GPU driver testing. Given the recently-stabilized NVIDIA R565 Linux driver series and then also the newest upstream code in Linux 6.13 Git and Mesa 25.0-devel for the AMD Radeon and Intel Arc Graphics hardware on their open-source drivers, here is a fresh look at where Intel / AMD / NVIDIA mid-range graphics stand today on Ubuntu Linux with the leading-edge drivers.

Video and image encoders/decoders written in the Rust programming language for its memory safety guarantees is often viewed as one of the compelling areas for the programming language to better protect against malformed/malicious content especially within web browsers. Not only are Rust-based PNG image decoders proving to be more secure than C-based decoders, but the performance of the Rust solutions can be even faster...
