The Linux Vendor Firmware Service (LVFS) for hosting firmware files to be consumed by Fwupd for firmware updating from Linux is on quite a streak...

Slated for Linux 5.9 is finally mainlining the FSGSBASE patches that have been floating around the kernel mailing list for years. Testing last week showed the tentative x86/fsgsbase patches helping Intel Xeon Linux performance but with AMD also supporting this instruction set extension going back to Bulldozer, how is it looking on the likes of AMD? Here are some benchmarks.

Over the weekend I began running some benchmarks of the Linux 5.8 development kernel on the Lenovo Flex 5 laptop with Ryzen 5 4500U. One of the standouts so far for from this Linux 5.8 testing compared to the stable 5.6/5.7 kernel series is better Radeon graphics performance with the Renoir laptop...

Following the announcement last week that future Apple computers will use in-house ARM-powered chips, some open-source projects have already begun prepping for the future ARM64-supported macOS 11...

Linux 5.6 brought initial USB4 support that primarily was starting things off by basing things off the existing Thunderbolt 3 support in the kernel for which this latest USB standard is based. For the Linux 5.9 kernel later this summer it's looking like there will be further work on getting Linux's USB4 support into good shape ahead of hardware appearing in the months ahead...

On top of an optimization to lower render times and reduce power usage and fixing window culling as another performance optimization, Canonical's Daniel van Vugt also came across another serious optimization for GNOME Shell's icon grid performance...

Prebiehajúca diskusia vývojárov by mohla viesť ku využitiu nástroja Nano ako základného textového editora alebo Btrfs ako štandardného súborového systému pre desktopy v nadchádzajúcom vydaní distribúcie Fedora 33.

Linus Torvalds just pushed out Linux 5.8-rc3 as the newest weekly test candidate for the upcoming Linux 5.8 that should debut as stable around early August...

[3 minuty čtení] V dnešním díle postřehů se podíváme na únik dat BlueLeaks, zneužití Google Analytics, záplaty od AMD a VMware, ohrožené Windows a Docker servery a na další zajímavosti ze světa výpočetní techniky. Skupina hackerů a zastánců transparentnosti publikovala 269GB dat údajně ukradených policii Spojených států amerických. Skupina zveřejnila stovky tisíc citlivých dokumentů z více než dvou set policejních oddělení a právo vymáhajících agentur ve Spojených státech.

While Ubuntu continues in their path of OpenZFS integration, Fedora is revisiting the possibility of using Btrfs on the desktop, Red Hat is continuing to invest in Stratis, and Reiser5 is being developed, Bcachefs as the file-system born out of the Linux block cache code is continuing to evolve...

Following Linux's UEFI code getting cleaned up earlier this year in preparation for RISC-V support being added and then some early RISC-V UEFI patches, a more comprehensive set of patches for enabling UEFI support on RISC-V under Linux have been sent out...

[4 minuty čtení] Množství zajímavých novinek chystá pro své uživatele Mageia s vydáním 8. Vedle toho se dnes podíváme na dva návrhy pro příští Fedoru: přechod na souborový systém btrfs a editor nano a také co nového v KDE. Nedostatek vývojářských sil a z toho plynoucí letité prodlevy ve vývoji nových verzích už u Mandrivy dávno nejsou výjimkou, stala se z nich spíše charakteristická vlastnost této distribuce. Však také u posledních verzí tvůrci nijak nespěchají s ohlašováním plánů na novinky a s časovou osou vývojových verzí. Každopádně na verzi Mageia 8 se pracuje a na světě je její první alfa, která samozřejmě není doporučena k běžnému používání a ani není podporován upgrade na ni z verze 7.

Our recent benchmarks have shown WSL/WSL2 performance on the latest Windows 10 builds to generally be quite good compared to running bare metal Linux. But past the May 2020 Update and on the latest Insider Preview builds is the initial support for GPU acceleration in conjunction with updated Windows graphics drivers. The initial emphasis is on GPU compute with DirectML and for NVIDIA hardware CUDA support as well. Here are a couple CUDA benchmarks that ran gracefully under WSL2 albeit the performance leaves a lot to be desired...

This leading open-source physically based renderer is about to get even better with the upcoming LuxCore 2.4 release...
