Svobodný software

Dnešním článkem bych se chtěl vrátit ke svému prvnímu publikovanému počítači Atari. U něj jsem z ničeho nic byl postaven před nutnost vyřešit další problém: nefunkční disketovou mechaniku.

Pravidelná sonda do světa software. Podíváme se na nástroj pro testování výkonu API endpointů, vytvoříme si vlastní znalostní síť a nakonec si uhladíme data v JSON formátu tak, aby byla čitelná.

With AMD continuing to be focused on their AMDGPU LLVM compiler back-end for their GPU compiler needs from compute to graphics shaders, the AMD GPU/accelerator hardware support within the GNU Compiler Collection "GCC" has long taken a backseat and left to third-party firms to implement. Posted today was an experimental patch providing very early support for the AMD Instinct MI300 series hardware with the GCC compiler...

The Linux 6.15 kernel cycle started off a bit rough with a heavy hitting performance regression spotted and then fixed but to only then discover another Linux 6.15 performance regression affecting modern AMD CPUs. Fortunately those issues were cleared out in time for the recent Linux 6.15 stable release. Linux 6.15 stable is looking good especially on 5th Gen AMD EPYC "Turin" servers with some recent benchmarks showing some modest gains over the Linux 6.14 kernel.

On the GNOME Foundation blog today is an interesting post how Amazon Web Services (AWS) has ended up sponsoring and powering all of the GNOME web infrastructure...

Along with releasing Linux 6.14.11 today to end-of-life the Linux 6.14 kernel series, Greg Kroah-Hartman released Linux 6.15.2 as the newest stable point release. There is a notable fix here for the CPU idle power regressing on some systems since moving to Linux 6.15...

DXVK 2.6.2 was released this morning as the newest update to this Direct3D 8 / 9 / 10 / 11 over Vulkan API implementation. DXVK continues to be most notably used by Valve's Steam Play (Proton) for running countless Windows games well on Linux...

Following last week's AMD Radeon RX 9060 XT Linux graphics/gaming review for launch day, today's article is providing an initial look at the GPU compute performance for this new RDNA4-powered ~$349 graphics card on Linux with ROCm 6.4.1.

In aligning with upstream GNOME 49 expected to ship with X11 support disabled by default, Canonical announced today that the upcoming Ubuntu 25.10 release will also ship without support for running the GNOME desktop on X11...

Going back to last year there have been patches worked on by SUSE for upstreaming Raspberry Pi's RP1 PCI device support. It looks like for the Linux 6.17 kernel later this year that work will finally be upstreamed...

An ongoing area of work for AMD's Linux client team is on enhancing the power management and overall power savings/efficiency support for Ryzen platforms on Linux. An updated patch series was posted on Monday for making the system S5 power state handling more ideal when powering off the system...

Last year there was some ideas raised around potentially making use of the Linux kernel's IO_uring functionality for graphics drivers to help with better performance and synchronization. It turns out Qualcomm engineers have recently been exploring IO_uring use for the DRM accelerator drivers with very promising results on their Cloud AI hardware in seeing around 50% speed-ups in ioctl execution time...

Following the release of Vulkan 1.4.317 back on Friday that brought the long-awaited VK_KHR_video_decode_vp9 extension for VP9 codec support for Vulkan Video, the Mesa RADV driver is now the first prominent open-source Vulkan driver merging support for VP9 decode...

As a nice stepping stone until FreeBSD 15 is ready to ship later in the calendar year, FreeBSD 14.3 stable is out today as the newest point release for this leading BSD operating system...

Going on since last year has been an effort to improve FreeBSD laptop support with backing by Dell, AMD, Framework Computer, Netflix, and others. This has focused on better WiFi driver support, enhancing power management, and other improvements for modern laptops. That work has been continuing on all fronts for improving the FreeBSD laptop user experience...

V pátek 6. června se už podesáté konala konference Den IPv6, na které se mluvilo o architektuře SRv6, směrování IPv4 provozu prostřednictvím IPv6 sousedů nebo situaci v českých mobilních sítích.

Už jsme se setkali s problematikou grafického subsystému. Dnes si ukážeme využití VBE (VESA BIOS Extension) pro nastavení grafických režimů s vyšším rozlišením a/nebo počtem barev, než nabízel standard VGA.

While Intel has supported CPUID Faulting on processors going back to Ivy Bridge and supported this feature in the Linux kernel since early 2017, only now the AMD support is being wired up and making use of the existing Intel code paths...

Last month with the launch of the AMD EPYC 4005 "Grado" series for entry-level Zen 5 servers we ran benchmarks of the AMD EPYC 4565P and EPYC 4585PX processors as the top-tier 16-core CPUs. They delivered an excellent combination of performance, power efficiency, and most of all value for those looking to assemble an AM5-based budget-oriented server in 2025 and beyond. Those processors destroyed the Intel Xeon 6300 series competition's flagship, the Xeon 6369P that is simply 8 cores / 16 threads in 2025... Being curious about the core-for-core performance between the AMD EPYC 4005 series and Intel Xeon 6300 series, I got my hands on an AMD EPYC 4345P as the Grado 8-core processor to see how it performs against that Xeon E-2400 series replacement as well as how the performance compares to the prior generation 8-core EPYC 4344P.

Používatelia distribúcie Linux Mint dostanú nový nástroj Fingwit, ktorý im zjednoduší prihlasovanie s odtlačkom prsta. Vývoj pokročil aj v prípade knižnice libAdapta a starým verziám Mintu 20 sa skončila podpora.
