Sonda do světa otevřeného softwaru. Dnes si navrhneme pružinové animace, vyzkoušíme textový editor, který „stojí míň za prd“, vygenerujeme si náhodný text a povíme si o zajímavém spouštěči aplikací.

XZ 5.8 is out today as the first notable feature release since last year's malicious backdoor in XZ 5.6 inserted by a then-co-maintainer of the project. XZ 5.6.2 was out last May while XZ 5.8.0 is now stable today for bringing new features to this lossless data compressor project...

Earlier this month for launch-day there were NVIDIA GeForce RTX 5070 Linux GPU compute benchmarks. The graphics/gaming benchmarks of the GeForce RTX 5070 on Linux were held up by waiting for a new R570 Linux driver release with proper support for this new Blackwell graphics card. Last week that new Linux driver arrived in the form of the NVIDIA 570.133.07 Linux build. That new NVIDIA Linux driver is working out great with the GeForce RTX 5070 Founder's Edition and in this article are some initial Linux gaming/graphics performance benchmarks for that new graphics card competing with the AMD Radeon RX 9070 series.

Over the past week a lot of new Rust "gccrs" code was merged into the GCC 15 compiler code-base as a big step forward for this open-source Rust front-end. Another big batch of patches have been merged with for-loops now working among other functionality...

An exciting new Linux kernel patch series was posted today for testing... Introducing support for cache-aware load-balancing. The patch comes from a veteran Intel Linux engineer but this cache aware load balancing may also prove very applicable for AMD Linux users for EPYC and Ryzen processors...

In addition to the Btrfs updates with real-time Zstd compression support and Bcachefs stabilizing its on-disk format, the Flash Friendly File-System updates have also been submitted already for the newly-opened Linux 6.15 merge window. There are a few exciting improvements for F2FS with this next Linux kernel version...

Building off yesterday's Linux 6.14 release, the GNU Linux-libre 6.14-gnu downstream is now available for this flavor of the Linux kernel that strips out support for hardware/drivers depending upon non-open-source firmware/microcode as well as the ability to load proprietary kernel modules and other tainted code...

The GRUB bootloader saw a set of 73 patches last month for addressing a variety of security flaws that were discovered...

V dnešním článku dokončíme návrh ISA procesoru MB5016. Popíšeme si jednotlivé skupiny instrukcí budeme se zabývat obsluhou přerušení a výjimek, včetně příslušných registrů a instrukcí.

Dnes se budeme zabývat vektorizací smyček, v nichž se zpracovávají pole (vektory), což vyžaduje instrukce SSE2 nebo AVX. Důležité bude taktéž zjištění, jak je vektorizován přístup k prvkům pole s volitelným krokem (stride).

GIMP 3.0 was 7+ years in development before releasing as stable last week for this much anticipated, GTK3-ported image manipulation program update. Thankfully we're not seeing any lengthy periods of time for new bug-fix releases with today already marking the release of GIMP 3.0.2...

Last month Bcachefs lead developer Kent Overstreet talked of Bcachefs getting to the point of freezing its on-disk format with future on-disk format updates slated to be optional. With today's Bcachefs pull request for Linux 6.15, it's now being treated as "soft frozen" and also landing other new features for this copy-on-write file-system. Among the new features is case insensitive file/folder support contributed by Valve...

David Sterba of SUSE sent in all of the Btrfs file-system updates today for the now-open Linux 6.15 kernel merge window. There are some new performance optimizations, new and faster Zstd compression level options, and other changes slated to be included for this CoW file-system in Linux 6.15...
