  • AMD Prepping Compute Shader Support For Video Compositor Rendering

    AMD's Linux graphics deriver developers are preparing a set of Mesa patches that allow for compute shaders to be used for the video compositor render process within Gallium3D's video layer code.

    This compute shader video compositor render support is within the common Gallium3D code but obviously written with AMD's RadeonSI driver in mind. Activating this compute shader support requires setting the CS_COMPOSITOR_render=true environment variable.

  • AMDVLK Driver Updated With Environment Variable To Enable Experimental Extensions

    AMD normally just does one code drop per week to their open-source "AMDVLK" Linux Vulkan driver code-base but now today marks the second time this week being greeted by new code. This latest release, v-2019.Q1.5, should provide for some fun weekend testing by Linux gamers preferring this driver over Mesa's RADV.

    Earlier this week saw the AMDVLK 2019.Q1.4 build with Vega 20 support as well as Raven 2 support. There were also some DXX fixes/adjustments, more VK_EXT_transform_feedback code being merged, and other changes.

  • Weston Adds Pixman Renderer Config Option

    In making it easier to persistently enable Weston's Pixman rendering code, the next Weston release offers up a configuration file option for flipping it on.

    The Pixman renderer for Wayland's Weston compositor is primarily used as a fall-back in the case the OpenGL (ES) renderer isn't working for one reason or another, but should you want to use this Pixman software-based rendering, it can now be enabled with the Weston configuration by adding use-pixman=true to the core section. Weston has long supported a --use-pixman switch when launching the compositor, but this option makes it easier should you want it to be persistent, etc.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. 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 the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
