Na předchozí článek o knihovně Go18DS dnes navážeme. Popíšeme si další dva velmi důležité kontejnery, konkrétně stromy (několika typů) a binární haldu. Ovšem nezapomeneme ani na benchmarky.

The Rust-GCC front-end that allows Rust code to be compiled with the GNU Compiler Collection (GCC) could possibly be upstreamed for next year's GCC 13 compiler release but not necessarily complete at that stage.

Merged today to Mesa 22.2 was a four month old merge request for the open-source Radeon Vulkan driver "RADV" that significantly improves the 16-bit FidelityFX Super Resolution (FSR) performance...

Coming about last week was a Fedora 37 change proposal to improve the profiling and debugging of Fedora packages but with possible performance costs. That suggested change is about adding "-fno-omit-frame-pointer" to the default CFLAGS/CXXFLAGS when building packages so the frame pointer is always available for improving the debugging/profiling of the stock Fedora packages. Unfortunately, it can come with significant performance costs as these benchmarks show.

One of Intel's many wonderful open-source projects for creators is OSPRay Studio that is their interactive visualization and ray-tracing application built atop their OSPRay portable ray-tracing engine. OSPRay Studio has been making steady progress since its 2020 debut and out today is their newest update...

Google engineers are working on the notion of "memory modes" for the Flash-Friendly File-System (F2FS) with the intent on introducing a "low memory" mode for storage devices that would alter its behavior. Presumably Google is working on this new F2FS feature for low-end Android devices...

Linus Torvalds just released Linux 5.19-rc4 as the newest weekly test candidate. There are more patches this week than in the prior Linux 5.19-rc versions but nothing too scary as well as having some notable patches in tow...

V dnešním souhrnu novinek ze světa bezpečnosti se podíváme na zranitelnost QNAP NAS a Citrix ADM, na DDoS útoky hrozící Litvě, na likvidaci jednoho botnetu, pokračující pokusy o zneužití Log4Shell a další zajímavosti.

Minimalistický operační systém Fedora CoreOS doufá v povýšení na oficiální edici. CBL-Mariner 2.0 podporuje PXE boot a kernel live patching. FreeNAS se spojuje s TrueNAS. Google uvolnil systém Fuchsia pro Nest Hub Max.

Jens Axboe, Linux storage expert and IO_uring lead developer, released liburing 2.2 this weekend as the newest version of this helper library that makes it easier for user-space software to make use of the Linux kernel's IO_uring support...

NVIDIA has contributed support to the FFmpeg multimedia library for being able to take advantage of AV1 GPU-accelerated video decoding by way of the VDPAU API when using the latest-generation NVIDIA RTX 30 "Ampere" GPUs...

Last month Microsoft issued the first production release of CBL-Mariner 2.0, its in-house Linux distribution used for powering services from Microsoft Azure to WSL use-cases and more.

For the Fedora 37 cycle Fedora CoreOS is hoping to be promoted to an official release "edition" alongside the likes of Fedora Workstation and Fedora Server...

2022 is certainly looking to be interesting on the open-source graphics driver front... You probably didn't have Imagination publishing an open-source PowerVR Vulkan driver on your 2022 bingo card nor NVIDIA working on an open-source GPU kernel driver. The latest 2022 surprise is the OpenChrome driver project is hoping to finally be mainlined in Linux 5.20 for open-source VIA graphics for those still running vintage VIA x86 hardware...

LLVM developers are eyeing Zstandard "Zstd" use within this compiler stack as a secondary compression method to Zlib. Zstd could be used for compressing ELF debug sections, AST data structures, and other purposes within this open-source compiler stack...

While Arch Linux itself is quite easy to get setup these days thanks to Archinstall for a quick installation process and sane defaults, for those looking for a nice and polished experience EndeavourOS remains one of the nice Arch-based desktop Linux distributions...
