[5 minut čtení] Apple udělal to, co většina certifikačních autorit udělat nechtěla: zkrátil maximální platnost vydávaných certifikátů na jediný rok. Certifikáty s delší dobou platnosti to tak mají vlastně za sebou. Apple tento týden na setkání zástupců certifikačních autorit a prohlížečů CA/B Forum v Bratislavě oznámil, že od 1. září tohoto roku bude maximální délka platnosti TLS certifikátů v Safari (a nejspíš i v celém macOS a iOS a všech aplikacích na nich spuštěných) pouze 1 rok, přesněji 398 dní. A to je skvělé, ale proč vlastně?

[4 minuty čtení] V dnešním bezpečnostním povídání se vydáme po stopách liščí kočky, trochu si zaemulujeme pod rootovskými právy, obveselíme izraelské vojáky sličnou děvou a zakopeme si se španělskou mičudou. Možná, že znáte Ezopovu bajku o kočce a lišce. Kočka uměla hbitě vyskočit a liška si myslela, že je nejchytřejší na světě. Íránská kočko-liška má, zdá se, zatím obě zmíněné schopnosti. Alespoň tedy na poli kyberkriminality.

[4 minuty čtení] Příští generace (i)GPU Intel bude podporovat 12bit VP9/H.265, začíná Google Summer of Code 2020, PipeWire 0.3 dostal nový scheduler s vyšším výkonem, příjmy z waferů rostou. Ač to zatím vypadá, že příští generace GPU architektury od Intelu známá jako XE, resp. Gen12 (v případě integrovaných jader) nezašlape konkurenci v prach, potěší video fanoušky. Intel v této generaci, která přijde do procesorů s architekturou Tiger Lake, nabídne podporu hardwarové práce s 12bit videem ve formátech H.265 (HEVC) a VP9. Na druhou stranu vývoj v ovladači od Intelu ukazuje, že naopak zmizí z VA-API podpora hardwarové akcelerace staršího formátu VP8.

PipeWire is the Red Hat engineered project aiming to offer better audio/video stream handling on Linux that integrates well with Flatpak and can optimally handle use-cases currently covered by the likes of PulseAudio and JACK. This week marked the release of PipeWire 0.3 as another big step forward for the effort...

Going back to the start of 2020 we've been seeing a few patches here and there around AMD Family 19h, almost certainly Zen 3. That patch work has continued with a few more bits out this week while hopefully more bring-up is on the horizon ahead of the Linux 5.7 merge window opening in just over one month's time...

Big "open-source" achievements aren't too common for NVIDIA or Microsoft much less together, but thanks to their open-source work on the DXC DirectXCompiler it's possible to easily convert HLSL DXR shaders to SPIR-V for Vulkan...

Vždycky je fajn si zpětně ohodnotit a oslavit plody své práce. Některé věci ale člověk tvoří tak dlouho, až na zdárně zdolané překážky, často provázené kriticky zvýšenou hodnotou krevního tlaku, prostě zapomene.

CodeWeavers working under contract for Valve on their Wine downstream Proton is out with a new update to their Proton 5.0 series...

While Clear Linux is well known as being the performance-optimized Linux distribution out of Intel and catered towards performing the best on their hardware (though as we continue to show, Clear Linux does also perform incredibly well on AMD hardware too and generally faster than other distributions), when it comes to AMD-optimized distributions the primary example remains OpenMandriva. Since 2018 OpenMandriva has been providing an AMD Zen optimized build where their operating system and entire package archive is built with the "znver1" compiler optimizations. As it's been almost a year since last looking at OpenMandriva's Zen optimized build, here are some fresh benchmarks using the newly-released OpenMandriva 4.1.
