Nejvyšší model procesoru Intel generace Arrow Lake je rok po svém uvedení jiným procesorem, než jakým byl při koupi. Intel opět dokazuje, že umí optimalizacemi vytáhnout ze svého železa o něco výkonu navíc, při současném snížení spotřeby.

Following up on the discussion from earlier this month among GCC developers over switching to C++20 by default for the GCC compiler as the default C++ standard when not otherwise set, that change has indeed happened. Merged now is the change defaulting to C++20 (well, the GNU++20 dialect) rather than C++17/GNU++17 when not otherwise specified when compiling C++ code...

In addition to Intel Arrow Lake desktop performance evolving nicely on Linux over the course of 2025, the Intel Arc B-Series graphics that launched last December with the Arc B580 have evolved quite nicely too with their open-source driver stack. With it coming up on one year since the Arc B580 launch, here is a look at how the GPU compute performance has evolved since that point. Similar Intel Arc B580 Linux graphics comparisons are also coming up in a follow-up comparison on Phoronix.

Zlib-ng 2.3.1 is out today as the first stable release in the v2.3 series for this Zlib replacement that carries a variety of performance optimizations for speedier compression/decompression...

For those Linux desktop users in the US needing another reason to be thankful this Thanksgiving, a huge and long-awaited accomplishment is ready for merging to the kernel: the Color Pipeline API that is important for HDR is ready for merging! As of last night the code is queued in DRM-Misc-Next for this years-in-the-making effort...

Just a few days ago I wrote about the Glibc math code seeing a 4x improvement on AMD Zen by changing the used FMA implementation. Merged overnight was a new generic FMA implementation for the GNU C Library and now yielding up to a 12.9x throughput improvement on AMD Zen 3...

Canonical announced today the Ubuntu 26.04 "Resolute Raccoon" Snapshot 1 images as their first monthly ISO snapshots of the upcoming Ubuntu 26.04 LTS release...

Two years and one week since the prior point release, Common Desktop Environment 2.5.3 is now available as the latest iteration of this Unix desktop environment built around the Motif toolkit. CDE has been open-source for more than a decade now but its development not exactly brisk. But for those resisting the likes of Wayland and other modern display tech -- especially with KDE announcing today Plasma 6.8 will be Wayland-exclusive -- CDE 2.5.3 is now available...

Originally opened in September 2020 by NVIDIA Linux engineer James Jones, tonight the Vulkan VK_EXT_present_timing extension was finally merged! Five years in the making and incorporating contributions from Google, NVIDIA, AMD, Collabora, Samsung, Unity, and Red Hat is this prominent new addition to the Vulkan API...

Umělá inteligence může být ve správných rukou dobrým pomocníkem. V minulém článku jsme si představili několik přístupů k programování s pomocí AI. Dnes si ukážeme programy, které tyto funkce implementují.

Zaměříme se na instrukce sloužící pro řízení toku dat (control-flow). Ty jsou použity při překladu zdrojových kódů s běžným rozvětvením, vícenásobným rozvětvením, programovými smyčkami i s ternárními operátory.

With the great upstream support for AMD Radeon graphics in the Linux kernel and Mesa, most desktop users / gamers / enthusiasts are best off just using the latest code shipped by their distributions or via the enthusiast-supported third-party archives/repositories. But for those on older enterprise Linux distributions, Radeon Software for Linux 25.20.3 was recently released for shipping that packaged AMD Linux graphics driver stack. This 25.20 series is the big one where they are now officially supporting the Mesa RADV Vulkan driver in place of their own former Vulkan Linux driver...

Following the release of ROCm 7.1 from just under one month ago, ROCm 7.1.1 is now available with expanded Linux operating system support, continued Instinct MI350 series work, more large language models working on RDNA4 GPUs, and other enhancements...

It's been just over one year now since the launch of the Core Ultra 9 285K and other Arrow Lake desktop processors. For those that may be considering an Arrow Lake CPU this holiday season for a Linux desktop or just curious how the power and performance has evolved one year later, here are some leading-edge benchmarks of the Intel Core Ultra 9 285K compared to the launch-day performance last October.

KDE developers announced they are going "all-in on a Wayland future" and with the Plasma 6.8 desktop it will become Wayland-exclusive. The Plasma X11 session is going away...

A Fedora special interest group is being proposed to help improve production stability of Fedora Linux and better handling incident management when problems do arise...

The Linux 6.18 kernel is anticipated for release this coming Sunday while this week a last-minute crisis was averted following reports of a kernel crash from recent ACPI code changes...

Společnost QNAP uvedla na trh rozšiřující úložnou jednotku TL-R6020Sep-RP, která umožňuje instalaci až šedesáti 3,5palcových pevných disků SAS/SATA v jednom 4U šasi. Lze tak vytvořit datová úložiště s efektivní kapacitou přes 1 PB v jediném zařízení s nižšími náklady na prostor a energii, což je ideální například pro kamerové systémy, big data aplikace a archivaci multimédií apod.

NVIDIA engineers are interested in helping Google bring Vulkan Video accelerated GPU video decoding to the Chrome/Chromium web browser...

Sean Christopherson of Google sent out the pull requests to the KVM tree of the various x86_64-related areas of virtualization he oversees. With these updates ahead of the Linux 6.19 merge window there is a significant overhaul of Intel's Trust Domain Extensions (TDX) code to address various outstanding problems...
