Ah the memories of old AGP graphics cards... But it's largely just that these days: distant memories. For anyone by chance still running an Accelerated Graphics Port (AGP) graphics card in production, FreeBSD is looking at deprecating its generic AGP driver and then potentially removing it in FreeBSD 15.0...

The first alpha release of OpenSSL 3.4 is now available for testing as the next feature update to this widely-used SSL library / cryptography toolkit...

With Linux 6.12 the Lunar Lake and Battlemage graphics are being enabled by default for out-of-the-box support with Intel's next-gen Xe2 graphics. Over in user-space the Intel OpenGL and Vulkan driver code has also begun enabling Xe2 graphics by default for use when running on Linux 6.12+. In Mesa besides no longer being hidden by the force probe option, a warning is now removed so users aren't told about unsupported Vulkan support when using Xe2 hardware...

Linux 6.11 merged getrandom() in the vDSO Support for very fast yet secure user-space random number generation needs. That work was initially focused on x86_64 but beginning with Linux 6.12 and following on this getrandom() vDSO implementation will see expanded CPU architecture support...

Succeeding OpenZFS 2.2.5 from early August is now OpenZFS 2.2.6 that brings various fixes plus newer Linux kernel compatibility...

QEMU 9.1 is out in stable form today as the newest feature release to this open-source processor emulator that plays a vital role within the free software Linux virtualization stack...

K zobrazení textové informace je potřeba písmo. Jeho volba významně ovlivňuje čitelnost textu a má velký dopad na uživatelský zážitek. Pojďme se podívat, jaké máme v písmech možnosti, jak je využívat, co dělat a čemu se naopak vyhnout.

Ještě jednou se vrátíme k modelu pro lineární regresi. S ním jsme se již setkali, ovšem ve skutečnosti je i zdánlivě jednoduchý koncept lineární regrese realizován tak, že ho lze využít mnoha dalšími způsoby.

Continuing on with the AMD Ryzen 9000 series Linux benchmarking, today's testing is looking at the performance and power impact of the AMD Ryzen 9 9950X when adjusting the CPU frequency scaling driver, governor, and Energy Performance Preference (EPP) tunable to help look at the performance and power efficiency characteristics of this current flagship Zen 5 desktop processor.

The Rust-written Redox OS open-source operating system has managed to address a performance bottleneck allowing this platform to perform much faster now when running as a virtual machine (VM) and for some synthetic benchmarks even able to run "slightly faster" than Linux...

Following yesterday's initial tuning of the "znver5" target for the AMD Zen 5 CPUs with the GCC 15 compiler, several more rounds of compiler tuning/optimizations were merged for benefiting the Ryzen AI 300 series, Ryzen 9000 series desktops, and upcoming EPYC Turin processors...

While using the older Qualcomm Snapdragon 8xc Gen 3 (SC8280XP) SoC and not the exciting Snapdragon X1 Elite, Linux kernel patches were posted this week for enabling the Microsoft Surface Pro 9 5G to boot with the mainline kernel...

Mozilla is interested in a Rust-written JPEG-XL image decoder for its memory safety characteristics compared to the existing C++ code they rely on for JPEG-XL image support in Firefox. While Google previously removed JPEG-XL support from Chrome/Chromium, it may be Google that comes to the rescue and writes a Rust-based JPEG-XL image decoder that can then be shipped by Firefox...

Linux 6.11 introduces block atomic write support including for NVMe and SCSI devices. With a new set of patches posted this week, atomic write support is wired up for the RAID0 MD code...

There are six accepted blocker bugs so far for the Fedora 41 Beta and three of them all pertain to Raspberry Pi issues...

Weston 14.0 was released today as the newest feature release for this reference Wayland compositor...

When it comes to the Rust programming language support within the Linux kernel one of the limitations is that the CPU architecture support isn't as widespread. Currently Rust for Linux supports x86_64, AArch64 (ARM64) little-endian, LoongArch, and RISC-V. While those cover the main targets, POWER is notably missing and many other niche CPU architectures supported by the Linux kernel especially for aging platforms. Patches posted today to the Linux kernel mailing list would extend the Rust support to MIPS...

Nová verze DNS serveru BIND 9.20.0 přináší významná vylepšení po dvou letech vývoje. Klíčové novinky zahrnují nové aplikační a databázové jádro, optimalizovanou podporu DNSSEC a vylepšenou kompresi DNS jmen.

Pravidelná středeční sonda do světa software. Dnes se podíváme na SQL klienta, budeme zkoumat elementy testovaných aplikací a nakonec si zaznamenáme čas strávený na projektech.

Google announced today that the Android 15 source code has been released to the Android Open-Source Project (AOSP)...
