Navštívili jsme meteoradar Skalky, kde se dálkově detekuje srážková oblačnost. Tady se získávají data pro mapy srážek, které používáme v mobilu i na webu. V pondělí vyjde obsáhlá reportáž, teď se podívejte na fotky.

During this year's X.Org Foundation elections there was the key ballot initiative on whether the X.Org Foundation should formally accept FreeDesktop.org into its umbrella. That measure, which required a super majority of members to approve, passed. But the X.Org Foundation Board of Directors voting hit an oops...

[3 minuty čtení] Steven J. Vaughan-Nichols roztančil prsty po klávesnici a připomněl tak nejen půl roku starý rozhovor s Linusem Torvaldsem, ale i pár témat, která do linuxového světa v posledních letech pronikla. Úvodem vzpomeňme inkriminovaný rozhovor z loňského října, kdy Swapnil Bhartiya tři čtvrtě hodiny rozprávěl s Linusem Torvaldsem (a také Gregem K-H).

Purism's Coreboot support for their laptops has evolved nicely over the past two years after initially not having support. While their devices have been shipping with Coreboot for some time now, Coreboot updates up until now have involved having to build them from source, but now they are offering pre-built binaries...

As has been expected the past several weeks, NVIDIA rolled out a driver update today providing DXR ray-tracing support going back to non-RTX Pascal GPUs. While NVIDIA has mostly been trumpeting the DirectX 12 ray-tracing abilities now with these older GPUs lacking RTX cores, their work does include enabling of Vulkan VK_NV_ray_tracing support on these graphics processors...

With the continuously evolving RADV Mesa Radeon Vulkan driver and near-weekly updates to the AMD's official "AMDVLK" open-source tree Vulkan driver, how are these competing AMD Vulkan Linux drivers comparing these days? As it's been a while since our last benchmarking comparison of the official AMDVLK driver against the open-source and more common/popular Mesa RADV driver, here are some fresh benchmarks of RADV from Mesa 19.0 on Ubuntu 19.04 as well as 19.1-devel compared to the latest AMDVLK driver code.

Proxmox VE 5.4 was released today as the server virtualization environment based on Debian and allows for easily deploying LXC containers and KVM-based virtual machines from a web-based interface...

The belated Mesa 19.0.2 is now available as the newest stable release to these open-source OpenGL/Vulkan drivers...

Seven years after Luc Verhaegen started the Lima driver project for open-source Mali graphics -- one of the first reverse-engineered, open-source Arm graphics driver attempts in general -- while he is no longer involved with the initiative, developer Qiang Yu picked it up and has successfully worked it into a functioning open-source OpenGL Gallium3D driver that has been merged into Mesa Git...

HDR (High Dynamic Range) je technologie zpracování obrazu, která rozšiřuje dynamický rozsah fotografie kombinováním několika obrazů téže scény s různou expozicí. Díky tomů tak lze vytvořit obraz, který svým dynamickým rozsahem překonává dynamický rozsah čipu fotoaparátu. V tomto seriálu si ukážeme několik způsobů, jak HDR obrázek sestavit.
