  • Linux 5.9 To Expose Adaptive-Sync / VRR Range Via DebugFS

    For aiding in testing and other purposes, the Variable Refresh Rate (VRR) range for FreeSync/Adaptive-Sync setups will now be exposed via DebugFS with Linux 5.9. 

    Sent in today was the latest weekly drm-misc-next round of updates. This includes many DRM core changes like NV15 / Q410 / Q401 YUV format support, uncompressed AFBC (Arm Framebuffer Compression) modifier support, and DebugFS reporting of VRR monitor ranges. There are also updates to the various smaller DRM drivers like Lima, Panfrost, and others.

  • Mesa 20.2 gets Valve-backed ACO shader compiler on by default for AMD RADV

    With the upcoming release of Mesa 20.2 which should hopefully be in late August, it seems AMD GPU owners will get a nice boost thanks to the Valve-backed ACO shader compiler.

    Introduced by Valve back in 2019, ACO was designed to replace the huge LLVM project in Mesa for AMD GPUs on Linux, with a specific focus on improving gaming performance. Yesterday, ACO was enabled by default in the Mesa 20.2 development code for the AMD RADV driver, with a note that "No more dragons have been seen, caution is still required...". There's also now a "RADV_DEBUG=llvm" environment variable you can set to force it back to LLVM for testing purposes.

  • Linux Foundation interview with NASA Astronaut Christina Koch

    Jason Perlow, Editorial Director at the Linux Foundation, had a chance to speak with NASA astronaut Christina Koch. This year, she completed a record-breaking 328 days at the International Space Station for the longest single spaceflight by a woman and participated in the first all-female spacewalk with fellow NASA astronaut Jessica Meir. Christina gave a keynote at the OpenJS Foundation’s flagship event, OpenJS World, on June 24, 2020, where she shared more on how open source JavaScript and web technologies are being used in space. This post can also be found on the OpenJS Foundation blog.

  • 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.
