  • Another Potential CPU Optimization For Mesa: Quadratic Probing

    Mesa developer Thomas Helland is looking at reviving an old set of Mesa patches that could help out in some CPU-bound scenarios.

    Helland re-discovered some old Mesa patches from April 2015 for implementing quadratic probing in hash tables for being faster rather than the linear re-probing hash table as is used currently. Helland explained further in the patch, "This will allow us to remove the large static table and use a power of two hash table size that we can compute on the fly. We can use bitmasking instead of modulo to fit our hash in the table, and it's less code. By using the algorithm hash = sh + i/2 + i*i/2 we are guaranteed that all retries from the quad probing are distinct, and so we should be able to completely fill the table."

  • Libinput X.Org Driver Updated With New Capabilities

    Libinput is the input handling library that originated with Wayland but has since been adopted by Mir as well as X.Org when using the xf86-input-libinput handling driver. This xf86-input-libinput adaptation for X.Org Servers has seen a new release today.

    Last month marked the libinput 1.6 release with new features to the input library. Now xf86-input-libinput has been upgraded for improving the support for this generic input handling implementation on xorg-server systems.

  • RadeonSI Working Toward Better Rocket League Performance

    Marek Olšák has posted a set of patches today to the Mesa mailing list and they should help some Linux games, at least Rocket League.

  • Wayland's Weston 2.0 Beta Released

    One day after the Wayland 1.13 Beta, the reference Weston compositor is updated to its 2.0 beta state.

    Wayland's reference compositor, Weston, is moving to version 2.0 rather than version 1.13 since its new output configuration ABI has broken Weston's ABI. In addition to the new output handling API, Weston 2.0 has seen work on DRM compositor improvements, support for using EGL_KHR_swap_buffers_with_damage, initial window positioning for XWayland apps, desktop shell refinements, and other improvements.

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.
