Bas Nieuwenhuizen on Ray-Tracing Support in RADV

 

• First Rays

  Given that the new RDNA2 GPUs provide some support for hardware accelerated raytracing and there is even a new shiny Vulkan extension for it, it may not be a surprise that we’re working on implementing raytracing support in RADV. Already some time ago I wrote documentation for the hardware raytracing support. As these GPUs contain quite minimal hardware to implement things there is a large software and shader side to implementing this.

  

• Mesa's Radeon "RADV" Vulkan Driver Makes First Steps Towards Ray-Tracing - Phoronix

  There still is much work left to be completed but Mesa's Radeon Vulkan driver "RADV" has made its first baby steps towards ray-tracing support with Radeon RX 6000 "RDNA2" series hardware.  RADV lead developer Bas Nieuwenhuizen announced his "first rays" progress in being able to provide RDNA2 Vulkan ray-tracing with the RADV driver. After hacking on the functionality the past few weeks, Bas hit his personal milestones including a fully recursive Fibonnaci shader and a ray-traced cube...

• How To Install Apache Subversion on CentOS 8 - idroot

  In this tutorial, we will show you how to install Apache Subversion on CentOS 8. For those of you who didn’t know, The Apache Subversion (SVN) is a free and open-source version control system used to manage and track changes in files and directories. Any time you change, add or delete a file or folder that you manage with Subversion, you commit these changes to your Subversion repository, which creates a new revision in your repository reflecting these changes. You can always go back, look at and get the contents of previous revisions. SVN supports several protocols for network access: SVN, SVN+SSH, HTTP, HTTPS. If you are behind a firewall, HTTP-based Subversion is advantageous since SVN traffic will go through the firewall without any additional firewall ruleset. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by-step installation of the Apache Subversion on a CentOS 8.

• Diskonaut: A Terminal Disk Space Navigator for Linux - LateWeb.Info

  Diskonaut is a simple terminal disk space navigator created using Rust and supports Linux, macOS and Windows. The usage of the app is very easy, specify an absolute path in your file system, or run it in any directory you want. It will scan the directory and convert it to memory, allowing you to explore its contents. It also allows you to check space usage even during the scanning process. When the scan is complete, you can navigate the subdirectories of interest and get a visual representation of a tree map of what consumes your disk space. diskonaut allows you to delete files and directories and as a result tracks the amount of space you have freed up in the process. It also supports keyboard shortcuts to facilitate navigation.
