It was just earlier this month that mainline Mesa achieved OpenGL 4.1 for Zink, the Gallium3D driver allowing OpenGL to be implemented atop Vulkan. Now OpenGL 4.2 support is in place for this promising Mesa component...

[3 minuty čtení] Red Hat oznámil, že od února rozšíří bezplatnou nabídku své linuxové distribuce Red Hat Enterprise Linux pro malá nasazení. Distribuci bude možné nasadit v menších produkčních prostředích a vývojářských týmech. V prosinci Red Hat způsobil velké pozdvižení tím, že oznámil konec projektu CentOS v jeho dosavadní podobě. Ten doposud fungoval jako nezávislý epigon, který svou distribuci vytvářel na základě zdrojového kódu distribuce Red Hat Enterprise Linux (RHEL).

Not only is the AMD "CPU frequency invariance regression" from that new support with the in-development Linux 5.11 kernel on course to address the performance shortcomings I outlined last month, but with the patched kernel for a number of workloads the performance is now ahead of where it was at with Linux 5.10.

Red Hat hasn't been the only major enterprise Linux distribution shifting around their pieces with regards to how RHEL is formed with moving to CentOS Stream as its future upstream. Over the past year especially openSUSE Leap and SUSE Linux Enterprise having been moving closer together with the source trees now being more closely aligned between Leap and "SLE". SUSE has published an insightful blog post series detailing the prior way that openSUSE Tumbleweed and Leap tied in with SUSE Linux Enterprise and then the direction they have been shifting...

Nadace Raspberry Pi Foundation představila nejmenší počítač ze své rodiny. Jedná se o jednočipovou destičku Raspberry Pi Pico, která je postavena na novém čipu RP2040. Nabízí spoustu portů, včetně analogových.

With the in-development Linux 5.11 kernel there are many great features and improvements especially for AMD users with some new drivers and other pleasant enhancements. But as I outlined back on Christmas day: Linux 5.11 Is Regressing Hard For AMD Performance With Schedutil. Fortunately, a fix is now en route to the Linux 5.11 kernel for fixing that performance regression affecting AMD Zen 2/3 desktops and servers...

Lightworks, the professional-grade video editing system that works well on Linux but has remained elusive of its long past open-source promise, is out with its first major release of 2021...

[8 minut čtení] První díl z nové série článků, která se bude zabývat ukázkou návrhu a postupu realizace některých základních funkcí distribuovaného informačního systému. Centrálním bodem bude message broker. Zabývám se návrhem a vývojem distribuovaných komunikačních systémů již řadu let. Tak jsem si řekl, že by nebylo špatné shrnout některé své zkušenosti a nabídnout je k širší diskuzi a použití.

[30 minut čtení] Funkce jsou jednou z nejužitečnějších abstrakcí používaných při vývoji. Jazyk R práci s funkcemi samozřejmě podporuje a funkce jsou zde dokonce plnohodnotným typem s podporou lexikálních uzávěrů i funkcí vyššího řádu. 1. Funkce v programovacím jazyku R

One of the last pieces of the puzzle for supporting an entirely Vulkan-based Wayland compositor is coming together with a new extension that looks like it will be merged soon and there already being work pending against Sway/WLROOTS to make use of the Vulkan path...

If Red Hat's new no-cost offering for up to 16 production systems for RHEL doesn't fit your requirements and are evaluating alternatives to CentOS 8 that will be EOL'ed this year, Rocky Linux remains one of the leading contenders and is on track for its inaugural release in Q2 of this year...

Following a very active past couple of days, developers from security startup Corellium have followed through on their word so far of publishing the Apple Silicon patches to the Linux kernel mailing list for possible upstreaming in the future that allow the Linux kernel to boot with Apple M1 hardware...

Following the announcement at the end of last year that CentOS 8 will be ending and instead focusing on CentOS Stream as the future upstream to RHEL, there have been many concerned by the absence of CentOS 8 past this year. In trying to fill that void, Red Hat announced today they will be making Red Hat Enterprise Linux free for small production deployments...

For those still making use of pre-GCN AMD graphics cards supported by the R600 Gallium3D driver (namely the Radeon HD 5000/6000 series), the open-source "R600g" Gallium3D driver now has nearly feature complete NIR support...
