  • Mesa 21.x Seems To Muck Up Gamers' Trust Factor For Counter-Strike: Global Offensive - Phoronix

    Those moving to Mesa 21.x releases for the latest open-source GPU driver support on Linux are seemingly finding their Valve "Trust Factor" matchmaking system scores dropping for Counter-Strike: GO, leading to numerous upset Linux gamers with AMD Radeon GPUs.

    Back in January for Mesa 21.0 there was the CS:GO whitelisting for OpenGL threading with a focus on improving the performance for the RadeonSI Gallium3D driver with modern AMD Radeon graphics cards. Unfortunately, that appears to be lowering the Trust Factor for the game. Valve's Trust Factor is their matchmaking system in use for Counter-Strike: Global Offensive for finding gamers to compete against with similar scores. Cheating and other opaque inputs go in to calculating the Trust Factor value for a particular game.

  • 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.
