Svobodný software

V sobotu 5. dubna proběhl v Bratislavě třetí ročník konference OpenCamp. Mluvilo se o bezpečnosti při programování, vyhledávání zranitelností, sítích v kontejnerech a otevřeném státu jako platformě.

Pravidelná sonda do světa software. Podíváme se na nástroj přetaktování grafické karty, budeme pracovat s PostgreSQL databázemi a nakonec vyzkoušíme přesun dat mezi PVC v Kubernetes.

The GCC 15.1 compiler release is expected in the coming weeks as the first stable version of GCC 15 as this annual GNU Compiler Collection release. As we approach the finish line, some last minute changes were merged for the AMD Zen 5 "znver5" CPU target...

Adding to the busy week of Linux distribution releases from Ubuntu 25.04 to Manjaro 25.04 and Fedora 42, TrueNAS 25.04 debuted today as a major step forward for this open enterprise storage platform...

Following the recent benchmarking of Ubuntu Server 25.04 in its near final state compared to prior Ubuntu Linux releases, I turned my attention to Fedora Server 42. On the same AMD EPYC 9005 "Turin" server I carried out some comparison benchmarks of Fedora Server 42 compared to the prior Fedora Server 41 and other Linux distribution releases for seeing how Fedora 42 is competing with other Linux distributions on this 5th Gen AMD EPYC dual socket server.

With the newest Mesa 25.1-devel Git code merged today the Panfrost Gallium3D and PanVK Vulkan drivers for Arm Mali open-source graphics are supporting Mali 5th Gen gen 1 (v12) and gen 2 (v13) devices...

Fedora 42 is out today as a fabulous update to this prominent leading-edge Linux distribution sponsored by Red Hat. I've been running Fedora 42 on several systems already -- including upgrading my main production system to it -- and it's been working out very well. Fedora 42 is packed full of new features and software updates making it a great H1'2025 Linux operating system release...

There's the possibility raised that the mainline Linux kernel might remove its file-system kernel drivers for Apple HFS and HFS+ this year...

The Intel Video Processing Library GPU Runtime "VPL-GPU-RT" as the run-time component to the Intel VPL API for video processing with a variety of video encoders/decoders and filters is preparing to end mainline support for Intel graphics prior to Tiger Lake...

The Datagram Congestion Control Protocol (DCCP) intended for online gaming, IP telephony, multimedia streaming, and other online real-time purposes for this transport layer protocol is expected to be stripped out of the Linux kernel with the upcoming v6.16 cycle...

In addition to yesterday's alpha release of the semi-immutable Majaro Summit distribution, Manjaro Linux has now resolved Manjaro 25.0 as the newest version of this (non-immutable) Arch Linux based desktop operating system...

Oracle today debuted the newest version of their Unbreakable Enterprise Kernel "UEK" designed to be paired with their RHEL-derived Oracle Linux operating system as a heavily-patched version of the Linux kernel. With today's release of UEK 8 they have rebased atop the current Linux 6.12 long-term support codebase...

CA/Browser Fórum odhlasovalo změnu maximální délky platnosti nově vystavovaných certifikátů. Zatímco dnes můžeme mít certifikáty uznávaných autorit v délce platnosti 398 dnů, připravuje se zkrácení na 47 dnů.

Dnes si ukážeme základy práce s instrukcemi AVX v assembleru, konkrétně v Netwide Assembleru běžícího v Linuxu. Samotné AVX (Advanced Vector Extensions) rozšiřuje možnosti vektorových instrukcí na x86 i x86–64.

After nearly one and a half decades after the packaging request was made, GNOME Shell Frippery extensions have finally worked their way into Debian via the unstable archive for offering a GNOME2-like desktop experience...

For fans of the Arch-based Manjaro Linux distribution, the distribution team announced the public alpha release of Manjaro Summit: a new semi-immutable flavor along similar lines to Fedora Silverblue, Nitrux, Aeryn OS, openSUSE Aeon, and others...

The work talked about back in January for improving the 32-bit PAE Linux kernel code for Physical Address Extensions to better jive with the code around Page Table Isolation (PTI) for mitigating the Meltdown vulnerability could soon be merged...

Earlier this month I looked at the AMD RDNA 3.5 graphics with Strix Point between Windows 11 and Ubuntu 25.04 Linux. The testing showed the AMD RDNA 3.5 graphics on the open-source Linux driver up to around 96% the performance of Radeon Software on Windows. The most frequent question that came up from that most recent round of benchmarking was wondering how the Intel Xe2 graphics on Core Ultra Series 2 "Lunar Lake" now compares between Windows 11 and Linux given that both drivers have been maturing the past several months. Here's the story of the Xe2 graphics between Windows 11 and Ubuntu 25.04 while using a Lenovo ThinkPad X1 Carbon Gen 13 Aura Edition laptop.

Being worked on for a while now by engineers from Amazon, Microsoft, and Google has been Kexec HandOver "KHO" as a means of allowing some kernel state to be retained when Kexec'ing into a new kernel such as for maintenance/security updates. The KHO patches in recent days were queued up into Andrew Morton's "MM" staging area leading to hope that this work is ready for mainlining with the Linux 6.16 kernel cycle this summer...

A decade after Intel acquired FPGA maker Altera for $16.7 billion and recently working to make Altera an independent company, Intel announced today it has sold 51% of its Altera business in a deal that values that business at $8.75 billion...
