Since Showtime replaced Totem as the default video player of GNOME, the desktop has lacked thumbnail capabilities for audio and video files. But to address that defect, the Rust-based gst-thumbnailers project has been in development to leverage GStreamer and paired with Rust to provide safe thumbnail generation capabilities for audio and video content...

The newest Mesa 26.0-devel code as of today has landed initial support for Qualcomm Adreno Gen 8 graphics into the Freedreno Gallium3D driver. The Adreno Gen 8 graphics so far are most notably used by the new Snapdragon X2 Elite laptop SoC with its X2-85 GPU as well as the new Snapdragon 8 Elite Gen 5 with Adreno 840 graphics...

Zaměříme se na praktickou stránku provozu zařízení: ukážeme si skript, který zajišťuje automatické přepínání režimů při připojení nebo odpojení klávesnice, ovládá zapínání a vypínání spodního displeje a řeší rotaci obrazovky.

Většina programátorů vytvářejících aplikace v Go používá překladač, který je součástí standardní instalace Go. Ovšem existují i alternativy, mezi než patří gccgo a TinyGo. Dnes se seznámíme se základními vlastnostmi TinyGo.

Beginning with the Linux 6.19 kernel, the hung task detector and system lock-up detector are now optionally able to provide greater insight into the issues by dumping additional system information. The new lockup_sys_info and hung_task_sys_info sysctl knobs were merged over as part of the pull requests managed by Andrew Morton...

Google engineers for the past number of months have been working on the Live Update Orchestrator as a new way of applying live Linux kernel updates. The Live Update Orchestrator "LUO" builds atop the Kexec Handover "KHO" functionality already within the kernel. Google has since been deplyoing LUO in their production environments for faster security updates to kernels, especially when involving VMs. LUO is now upstream in Linux 6.19...

Meson 1.10 is out today as the newest feature release for this popular cross-platform build system...

The Mozilla Firefox 146.0 release binaries are now available with a very exciting improvement for Linux users relying on Wayland...

Recently there were Phoronix benchmarks looking at the Intel Battlemage GPU compute performance since last year when the Arc B580 graphics card launched as well as the OpenGL and Vulkan graphics performance for the B580 on Linux since launch. There was much progress on the open-source Intel Linux graphics drivers at large this year but especially for Battlemage. Following that a Phoronix Premium reader asked about seeing some fresh Llama.cpp AI benchmarks with its Vulkan back-end now for the Arc B580 compared to competing AMD and NVIDIA graphics cards. Here are those benchmarks as requested.

While just half-way through the Linux 6.19 merge window, over the weekend I began running some benchmarks of the current Linux 6.19 Git state compared to Linux 6.18 LTS stable. There are some minor performance improvements to note in a few of the tests on the first system I tested but also some regressions at this very early pre-RC1 state of the Linux 6.19 kernel...

One of the new Linux engineering initiatives out of AMD is working to further enhance Linux performance on today's large core count systems by introducing push-based load balancing...

Do zoznamu noviniek novej stabilnej verzie distribúcie Alpine Linux 3.23 sa opäť dostali aktualizácie softvérových balíčkov. Dostupná je aj nová verzia apk v3 a balíček jadra linux-edge má iný názov a konfiguráciu.

All of the Human Interface Devices (HID) subsystem updates were merged a few days ago for the ongoing Linux 6.19 kernel merge window. Standing out this cycle on the HID side are seeing new/improved support for several Logitech devices...

I2C in Linux 6.19 brought support for Rust-written I2C drivers. The newer I3C "Improved Inter-Integrated Circuit" interface changes have now been merged and the big feature there is HDR support. Not to be confused with the more common High Dynamic Range acronym usage for HDR, HDR in the I3C context is for the "High Data Rate" mode for facilitating faster data transfers...

The ARM64 code changes were merged last week into the in-development Linux 6.19 kernel. The most notable of the ARM64 architecture changes this cycle is landing the Arm MPAM driver for Arm's Memory System Resource Partitioning and Monitoring...

Větev Tumbleweed systému openSUSE změnil výchozí zavaděč z GRUB2 na GRUB2-BLS. Projekt Fedora zlepší zpracování poškozených balíčků. Spolu s uvedením levnější varianty Raspberry Pi 5 s 1 GB RAM došlo ke zdražení stávajících modelů.

Released today is a new version of Iced, the popular cross-platform GUI library for the Rust programming language. Iced is notably used by the COSMIC desktop environment and a growing variety of different Rust apps...

Týden započneme odhalením náborové kampaně severokorejských Chollimas – kdo by nechtěl peníze bez práce?! Dále opět zabrousíme do zranitelného AI, zmíníme React2Shell a navštívíme Indii a jejich nařízení.

Moduly se do C++ dostaly s verzí 20 a byly doručeny jen jako papírový „koncept“, než reálná funkční věc. Po skoro dvou letech se k nim vracím. Už se to dá používat? Jak daleko se posunul vývoj? A jaké máme nástroje?

Merged to the mainline Linux kernel last year was GPIB drivers in the kernel's "staging" area. GPIB is the General Purpose Interface Bus launched by HP back in 1972 for lab equipment and more. After a year of cleaning up the code in the kernel's staging area, for Linux 6.19 the GPIB drivers have been promoted out of the staging area and into the Linux kernel proper. The Linux kernel now has stable driver support for this 8 Mbyte/s parallel bus that was introduced 53 years ago...
