  • Wayland Has A Color Manager Calibration Protocol In The Works

    The latest Wayland protocol in the works is a color manager calibration protocol.

    This experimental protocol is designed to allow a compositor to calibrate a given output, an interface for a calibration/profiling application to send the needed colors to the display, an interface to inform the application of the display depth, setting a specific color on an output, loading an ICC profile for a compositor, and saving the last profile loaded.

  • Nouveau Developer Working On OpenGL Extension To Help With Reverse-Engineering

    Longtime open-source NVIDIA "Nouveau" driver developer Ilia Mirkin is drafting a new OpenGL extension proposal for helping out in driver reverse-engineering efforts.

    The proposed GL_MESA_debug_operations extension is about making it easier to insert arbitrary commands into existing shaders to better understand these operations in different combinations. This extension is designed to help reverse engineering activities like Nouveau as they try to understand NVIDIA's hardware behavior but could have use-cases by other reverse-engineered OpenGL drivers like Freedreno, Panfrost / Lima, Etnaviv, and others. It's also possible this could be used as a sorts of testing/fuzzing different shader operations/behavior.

  • Unigine Superposition 1.1 Adds Linux SteamVR Support, Up To 16K Rendering

    It's already been two years since Unigine Corp introduced their very fascinating Superposition graphics benchmark. Today they have rolled out Unigine Superposition 1.1 as the next installment of this demanding GPU benchmark to showcase the Unigine 2 engine's abilities.

    While most of you were probably hoping this Unigine benchmark update would bring Vulkan API support, sadly it does not. The Unigine 2 engine doesn't yet support Vulkan but the company is said to still be working on that support to complement OpenGL on Linux systems. Unigine Superposition 1.1 still relies upon OpenGL but with this release now supports up to 16K x 16K rendering.

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.
