  • Zink Is Now OpenGL 3.0 Complete For Generic GL Over Vulkan

    A few days ago I wrote about Zink now exposing GLSL 1.30 shader support as one of the few remaining hurdles for exposing OpenGL 3.0 support for this Gallium3D OpenGL-on-Vulkan implementation. It turns out this same week, Zink would already cross the significant OpenGL 3.0 milestone.

    As of this morning, Zink has now marked its OpenGL 3.0 support as complete with all necessary functionality being exposed.

  • RADV+ACO Lands FP16 Features - One Step Closer To Making ACO The Default

    The Mesa Radeon Vulkan "RADV" driver's ACO shader compiler back-end has merged its FP16 related bits and in turn putting the ACO back-end very close to being enabled by default for this open-source AMD Vulkan driver.

    VK_AMD_gpu_shader_half_float, VK_AMD_gpu_shader_int16, and shaderFloat16 are now working and enabled when using the ACO back-end. The work was merged on Wednesday for Mesa 20.2.

  • AMD Posts New AMDGPU Patches For UVD Video Decode For GCN 1.0

    One of the main blockers from AMD Radeon GCN 1.0 "Southern Islands" GPUs achieving feature parity when using the newer AMDGPU DRM kernel driver rather than the older "Radeon" DRM kernel driver has been in regards to UVD video decoding. But in 2020 it looks like that might finally change.

    For years there have been experimental patches for UVD with GCN 1.0 on the AMDGPU driver albeit never merged and hasn't come up now in several years. But surprisingly today an AMD engineer posted new patches for bringing GCN 1.0 UVD support to AMDGPU.

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.
