Nové Ubuntu je na světě a jde o první verzi po LTS vydání, pročež Canonical již tradičně posouvá hranice dál. Přivítejme tak třeba GNOME 43, PipeWire a vylepšenou podporu architektur ARM či RISC-V.

If as an Ubuntu Linux user you have been held off on purchasing one of the new Arc Graphics discrete graphics cards due to the prospects of having to upgrade your own kernel, Mesa, and linux-firmware packages, Intel has a solution for Ubuntu 22.04 LTS users in the form of a packaged driver...

Earlier this year Coreboot and the Dasharo downstream were ported to the MSI PRO Z690-A DDR4 motherboard. This was very exciting in that a current-generation Intel desktop motherboard could run Coreboot and readily available through various Internet retailers. But many inquired about whether the MSI PRO Z690-A DDR5 variant would see similar support and now that too is being worked on...

After last month launching the redesigned Thelio chassis, System76 today has rolled out their latest System76 Thelio desktop options with Intel 13th Gen Core "Raptor Lake" and AMD Ryzen 7000 "Zen 4" processor options now available...

The widely depended upon GNU C Library "glibc" has seen another round of optimization work for benefiting those with AVX-512 processors from Intel or now on the AMD side too with Zen 4...

Back in August 2021 saw initial patches by Intel for "FineIBT" for the Linux kernel as aiming to combine the best of their Control-flow Enforcement Technology (CET) and Control Flow Integrity for upping the kernel security protections in an efficient manner...

A first batch of "drm-misc-next" patches have been sent in for DRM-Next to queue until the Linux 6.2 merge window comes about in December. With this initial batch of new material for v6.2 is a new Direct Rendering Manager driver: OFDRM...

The open-source SVT-AV1 encoder for AV1 content that is primarily developed by Intel software engineers continues getting faster and finding new ways to provide better tuned presets and yield better performance for AV1 encoding on CPUs...

Corsair this summer launched the HX1500i power supply as the latest in their HX series. The Corsair HX1500i provides three EPS12V connectors, a fully modular design, and as implied by the model is sized for providing 1500 Watts. This $399 USD power supply can now also interface with the Linux kernel for monitoring support...

V první části článku dokončíme popis problematiky SIMD technologie NEON na architektuře ARM. Část druhá bude věnována takzvaným intrinsic, které programátorům umožňují přímo v C provádět i nízkoúrovňové optimalizace.

Dnes si představíme nástroj pro kontrolu stavů portů a služeb, budeme spravovat lokální repozitáře, vyzkoušíme univerzální herní launcher a nakonec se budeme dotazovat na grafické procesorové jednotky skoro jako v SQL.

While the Linux 6.1 merge window just passed and the "Call Depth Tracking" patches have been in development the past few months, it looks like that for the Linux 6.2 kernel is where that alternative mitigation technique will be introduced for helping offset some of the significant performance regressions incurred for Intel Skylake era processors as a result of recent CPU security vulnerability mitigations...

Two weeks ago was the release of systemd 252-rc1 with introducing the new systemd-measure command, a "support-ended" taint flag for OS images detected past their end-of-support date, and a wide variety of other changes and feature additions.

If you habitually ride Mesa Git for the latest and greatest open-source AMD Radeon graphics driver code and use the KDE Plasma desktop with Wayland, you may have noticed a glitchy cursor recently. Fortunately, that's now fixed up with today's Mesa Git code and ended up stemming from the recent global enabling of Mesa OpenGL threading...

Last week saw Intel sending out new GCC compiler patches for adding the "Sierra Forest" CPU target and the number of new x86_64 instructions it's adding. Those GCC patches follow Intel publishing an updated programming reference manual where they detailed these new instructions coming for Sierra Forest Xeon CPUs as well as Grand Ridge. Now on the LLVM compiler side, they too have begun landing new patches for these new Intel instructions...
