Updated FUTEX2 Patches Posted For The Linux Kernel With A Focus On Helping Games

Submitted by Roy Schestowitz on Monday 15th of February 2021 06:18:12 PM Filed under
Linux
Gaming

It's approaching one year since the proposal of FUTEX2 for addressing shortcomings of the existing FUTEX system call and allowing the semantics to better match that of the Windows behavior, which is of use when running Windows games on Linux via Steam Play's Wine/Proton. In the end the FUTEX2 system call can lead to lower CPU utilization and in turn allowing for greater Linux gaming performance.

André Almeida of Collabora today posted the latest patches introducing the FUTEX2 system call though with these patches are still marked as "request for comments" (RFC) so don't expect them to be merged to mainline in short order -- plus the fact that it would already be too late for trying to get it into the now-open 5.12 merge window.

  • 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.
