In addition to Intel this week sending out their first big batch of graphics driver changes for the Linux 5.5 kernel cycle kicking off at year's end, today AMD developers sent in their first batch of AMDGPU/AMDKFD kernel driver changes targeting this next version of the Linux kernel...

There hasn't been a major release of the X.Org Server now in 17 months... Not because there haven't been any changes (in fact, a lot of GLAMOR and XWayland work among other fixing) but because no one has stepped up as release manager to get the next version out the door. But to workaround that, developers are looking at moving the X.Org Server to purely time-based releases and letting their continuous integration testing be the deciding factor on if a release is ready to ship...

While Ubuntu developers are busy adding experimental ZFS support to their installer, the SUSE developers working on their YaST installer are working on offering better security options for their platform by beefing up the encryption capabilities at install-time...

RenderDoc has already been the leading open-source graphics debugging tool for OpenGL / Vulkan / Direct3D across multiple platforms and it continues only getting more useful with each new feature release...

Google's newest open-source contribution for benefiting the Linux kernel is SchedViz...

[2 minuty čtení] Dovolte mi další krátký díl našeho „nekonečného“ seriálu o zvyšování bezpečnosti provozu DNS pro .CZ doménu. Tentokrát o tom, jak jsme instalovali další uzel naší anycastové sítě. Tentokrát v Miláně. Zřejmě proto, že jeho poslední zveřejněný díl znamenal upgrade v řádu 100 GE, a také proto, že naši administrátoři mají plné ruce práce se stěhováním do privátního sálu, tento vychází poněkud zpožděný a navíc z mé klávesnice.

[46 minut čtení] Dnes si ukážeme, jakým způsobem lze zajistit zveřejnění různých metrik službami či mikroslužbami, které jsou naprogramovány v Go. Metriky mohou být zaznamenány a zpracovány systémem Prometheus a vizualizovány pomocí Grafany. 1. Monitoring služeb a mikroslužeb psaných v Go nástrojem Prometheus

[2 minuty čtení] V minulých dílech jste se mohli dočíst, jak funguje IQRF, jak si snadno postavíte síť ze zařízení komunikujících touto bezdrátovou technologií a jak můžete v síti komunikovat a získávat například senzorické hodnoty. Aby byla komunikace stejného typu na zařízeních od různých výrobců jednotná (např. čtení teploty nebo rozsvícení světla), začala IQRF Alliance spolu se svými členy před třemi roky pracovat na definici standardu. Zařízení, které je pak certifikováno na IQRF interoperabilitu, splňuje tento standard, a proto je velmi snadné zařadit takové zařízení do sítí obsahující nejrůznější zařízení od různých výrobců, protože komunikace s nimi je předem daná a jednotná.

With Stallman sticking around as head of the GNU and with that the Free Software Foundation re-evaluating their GNU relationship, Richard Stallman is already saying there will be no major changes to the project he founded...

Last week I shared benchmark results of the AMD Ryzen 9 3900X vs. Intel Core i9 9900K in 400+ benchmarks in the largest comparison ever for these two competing ~$500 USD processors. If that wasn't enough, I repeated the hundreds of CPU/system benchmarks again but without any of the recent CPU security mitigations in place to see how the situation would have played out pre-2018.

The Qt Company has shipped Qt 5.14 beta as the newest version of the Qt5 tool-kit and their last real feature update as Qt 5.15 will focus more on bug fixes as development is shifting towards Qt 6.0 due out in one year's time...

Currently when resuming from systemd suspend or switching back to the KDE desktop from an alternate VT, it's possible with the NVIDIA proprietary driver to see screen corruption or leakage of previous screen contents to areas of the lock screen / desktop. This annoying issue is now being better addressed with Qt 5.14...

As we reported this weekend, the Ubuntu desktop installer "Ubiquity" has landed the much anticipated ZFS install support. That's now propagated through to the Ubuntu 19.10 daily ISOs and does indeed make for a quick and easy setup of Ubuntu Eoan running off a root ZFS file-system...
