Sonda do světa otevřeného softwaru. Dnes integrujeme AirPlay do prostředí GNOME, vyzkoušíme muultiplatformní e-mailový klient, připojíme se sociální síť Bluesky přes terminál a upravíme se videa s ohledem na fyziku.

That Flatbox app sandboxing and distribution system is out today with important security updates...

Jay is a new open-source shader compiler being developed for Intel's open-source OpenGL and Vulkan Linux drivers. Ultimately this Jay shader compiler should help in delivering better Linux graphics performance with modern Intel hardware...

For those that like to make remarks about AMD "fine wine" especially when it comes to open-source Linux drivers and/or nostalgic about feature work on really old hardware, to much amusement there are new patches today for the AMD InterWave ISA sound card from the 1990s...

Last week I provided benchmarks to quantify how the AMD Strix Halo graphics performance has evolved since launch one year ago, in today's article is a look at how the Zen 5 CPU performance with the flagship Ryzen AI Max+ 395 has evolved under Linux in the year since these exciting APUs began making their way to high-end laptops and desktops. Complementing the nice Radeon 8060S performance gains are also some nice CPU performance benefits quantified when using Ubuntu 26.04.

The Intel QuickAssist "QAT" driver for the mainline Linux 7.1 kernel is adding support for Zstd offloading across QuickAssist Gen 4 / Gen 5 / Gen 6 accelerators for Zstandard compression as well as Zstandard decompression (limited there to the latest Gen 6 hardware)...

Greg Kroah-Hartman, the main Linux stable kernel maintainer and typically viewed as the second-in-command to the Linux kernel development, has turned to new "gregkh_clanker_t1000" fuzzing tooling to help uncover new kernel bugs...

Framework Computer on Monday issued their latest update concerning the ongoing price increases for memory and solid state drives affecting the industry. There has been some more price increases, signs of some temporary reprieve, and then a bit of good news on pricing for select Framework hardware...

It looks like with the Linux 7.2 kernel later in the year the AMD ISP4 driver will finally be merged to mainline. This driver is needed for the web camera on the HP ZBook Ultra G1a Strix Halo laptop and other future AMD Ryzen laptops...

Introduced in Linux 5.13 back in 2021 was eXecute In Place "XIP" support for RISC-V that allows for the kernel image to be executed from ROM. The intent is on allowing the kernel to run from non-volatile storage like NOR flash that is directly addressable by the CPU and to reduce RAM usage. But after RISC-V XIP support is broken for months at a time, the feature is now set to be retired from the mainline kernel...

It doesn't change too much in practice with how Mesa updates typically have been handled under Fedora Linux, but now it's officially documented: Mesa graphics drivers have a permanent updates exception so new Mesa versions can be shipped as updates in Fedora stable releases...

Following last month's Lemonade SDK 10.0 release that finally makes AMD Ryzen AI NPUs under Linux useful for running large language models (LLMs) where as before the Linux build could only target GPUs, released on Monday was Lemonade 10.1 with more enhancements to this local LLM solution...

Building on prior Mesa contributor guidelines and discussions among upstream Mesa developers, there are two generative AI "GenAI" policies that have now been decided upon for Mesa development moving forward...

Rust Coreutils 0.8 was released today as the newest major release to this alternative to GNU Coreutils...

Vydání nové verze distribuce antiX založené na Debianu 13 tentokrát trvalo poněkud déle, ale výsledek rozhodně stojí za to. Vyzkoušejte lehkou distribuci, která poběží svižně i na 32bitovém počítači se 4GB RAM.

Knihovna SciPy obsahuje i funkce pro zpracování signálů ve frekvenční oblasti, resp. umožňuje signály do frekvenční oblasti transformovat. Dnes se s těmito funkcemi seznámíme. Bude se jednat o výpočet FFT, ale i zpětné FFT a DCT.

Over the past year the FreeBSD project has been making much progress on making it more viable to run this BSD operating system on laptop hardware. They have worked on better graphics driver support, improved power management / suspend, making sure audio is working, and even rolling out a KDE desktop option from the FreeBSD OS installer to ease the deployment on desktops. While that engineering work continues, they are also working now to make it easier to summarize laptop hardware working or not on FreeBSD...

A small but convenient feature is coming with the Linux 7.1 that will be useful in debugging AMD Zen system problems and information reporting/transparency purposes...
