Mesa 18.2 as the next quarterly feature release to the contained OpenGL/Vulkan drivers is about two weeks out if all goes well, but today for testing Mesa 18.2-RC3 is now available...

Yesterday the latest speculative execution vulnerability was disclosed that was akin to Meltdown and is dubbed the L1 Terminal Fault, or "L1TF" for short. Here are some very early benchmarks of the performance impact of the L1TF mitigation on the Linux virtual machine performance when testing the various levels of mitigation as well as the unpatched system performance prior to this vulnerability coming to light.

QEMU 3.0 is now officially available. This big version bump isn't due to some compatibility-breaking changes, but rather to simplify their versioning and begin doing major version bumps on an annual basis. As an added bonus, QEMU 3.0 comes at a time of the project marking its 15th year in existence...

[4 minuty čtení] Vloni jsme začali pracovat na projektu celkového posílení infrastruktury autoritativních DNS serverů zabezpečujících provoz .CZ domény. Hlavní motivací bylo zvýšit odolnost DNS infrastruktury proti DoS útokům. V předchozím díle seriálu o upgrade DNS infrastruktury jsem popsal proces výběrového řízení na 100GE router, switche a servery. Dnešní díl bude věnován přípravě zázemí v datacentru, konkrétně výběru racku a jeho součástí.

[1 minuta čtení] Sonda do světa otevřeného softwaru. Dnes se podíváme na přizpůsobitelnou virtuální klávesnici, vyzkoušíme nástroj pro testování webových stránek, vytvoříme spustitelný soubor z python skriptů a nakonec si ověříme integritu souboru. Celým názvem Unicode Virtual Keyboard je virtuální klávesnice postavená na JavaFX, se kterou můžete procházet znaky dle kategorií, vyhledávat znaky na základě jejich názvu, přidávat a mazat znaky, přistupovat k často používaným a oblíbeným znakům rychleji, kopírovat je do schránky či vkládat do jiných aplikací. V okně je zobrazen i přehled nedávno použitých kláves (znaků).
