Intel Open Image Denoise 2.2 s rychlejším během na CPU, opravná verze Mesa 24.0.1, KDE Plasma 6.0 za méně než týden, dav1d 1.4 s dalšími AVX-512 optimalizacemi.

The GNOME 46 beta is out today for featuring the latest fixes and last-minute enhancements to this open-source desktop environment update due out in March...

System76 has been developing the Rust-based COSMIC desktop for their Pop!_OS Linux distribution but its usage won't be artificially limited to that in-house distro. Among other distributions that have been looking toward packaging it, interest is currently being evaluated in creating a Fedora special interest group (SIG) for the COSMIC desktop environment...

The Ubuntu 24.04 LTS desktop installer has rolled out accessibility options built into the initial GUI for helping enable additional features...

While recent graphics cards support GPU-accelerated AV1 video decoding, for those still relying on dav1d for CPU-based AV1 decode there is now version 1.4 "Road Runner" available that adds support for LoongArch and RISC-V architectures while continuing to further enhance the performance of this open-source AV1 decoder on x86_64 Intel/AMD processors too...

There is just two weeks to go until the much-anticipated KDE 6 Mega-Release that includes KDE Plasma 6.0, KDE Frameworks 6, and the updated KDE Gear apps. KDE developers continue fixing bugs as well as already working on KDE Plasma 6.1 features...

A merge request was opened this week for plumbing fractional scaling support for XWayland clients running on the GNOME Mutter compositor...

Longtime Linux kernel developer Thomas Gleixner with Intel-owned Linutronix has been spending much time over the past several months reworking the Linux kernel's x86 CPU topology evaluation code. This is to clean-up a mess of aging kernel code as well as some areas of the code being incorrect in today's era of hybrid Intel Core processors with a mix of P / E cores with the E cores lacking SMT/HT and thus throwing off prior kernel assumptions. With the code now queued up in a TIP branch today, it looks like that CPU topology rework could be good to go with Linux 6.9...

The FreeBSD project today issued their Q4'2023 status report that highlights all of their interesting work accomplished last quarter on this open-source platform. Among the interesting achievements were the FreeBSD Foundation sponsoring AMD64 SIMD improvements for FreeBSD 15 that will also be back-ported to FreeBSD 14.1...

Merged to the LLVM compiler stack two years ago was the BOLT tool for optimizing the layout of generated binaries for offering even greater performance than the likes of Profile Guided Optimizations (PGO) alone. BOLT had been in development for years by Facebook/Meta engineers and has continued to be improved upon for enhancing the code layout of binaries to yield enhanced performance. Recently there's been renewed work on using BOLT to optimize Linux kernel images...

Ahead of the SUSE/openSUSE Adaptable Linux Platform (ALP) their engineers have been working on a new web-based OS installer. Originally known as the "D-Installer" and now going by the "Agama" name, this new installer architecture has plans for many architectural improvements this calendar year...

Intel engineers working on their open-source Mesa OpenGL/Vulkan driver code currently replay captured error state / GPU hangs using a simulator, but a new patch proposal allows for replaying GPU hangs on the actual hardware. In turn this will hopefully help Intel driver developers better address some real-world issues...

Iced is the Rust GUI library that's been gaining quite a lot of interest by Rust developers for creating cross-platform user interfaces. Iced is also what's being used by the Pop!_OS COSMIC desktop environment. Iced v0.12 released yesterday as the first new release for this GUI toolkit since last July...

Valve's Linux graphics driver team has fixed the Vulkan mesh shader support for those using RDNA3 integrated graphics with Phoenix APUs on the latest Mesa RADV driver code...

Vulkan 1.3.278 was published this morning and in addition to the usual documentation corrections/clarifications, there are also two new Vulkan extensions in tow...

V tomto článku bych rád navázal na předchozí zabývající se klasifikací EKG signálů s využitím konvolučních neuronových sítí. Na problematiku bych se chtěl ale podívat poněkud z jiného úhlu.

AMD on Valentine's Day released an updated Radeon Software for Linux packaged driver stack for enterprise Linux operating systems that targets the Radeon RX 7900 series and Radeon PRO W6800 / W7800 / W7900 graphics cards...

Dvě nové zranitelnosti umožňují zahltit DNS resolver a zastavit jeho běžné fungování. Vývojáři totiž neposlouchali rady tvůrců DNS a jejich doporučení. Silná komunita naštěstí dokázala problém vyřešit.

GhostBSD as one of the few actively maintained desktop-focused BSD distributions is out with a new release this week...
