  • The Work Ahead For Ubuntu 21.04 To Switch To Wayland By Default

    Last month was the delightful news that Ubuntu 21.04 is aiming to use Wayland by default for non-NVIDIA systems on the GNOME desktop rather than the X.Org session. While there is two months to go until the Ubuntu 21.04 release, there still is more work ahead in making that shift a reality.

    The Ubuntu developers working on the Wayland-by-default transition have made their Trello workboard now public and it offers a glimpse at some of their planning and challenges around this significant shift in moving to Wayland by default. Their motivation in doing so now is to ensure that by Ubuntu 22.04 LTS next year the Wayland support will be shining and in excellent shape given that it is a long-term support release.

  • There's Finally A Decent Vulkan Ray-Tracing Benchmark

    While so far only the NVIDIA proprietary driver on Linux supports the Vulkan ray-tracing extensions, eventually we will see support for these new Vulkan extensions with the AMD Vulkan drivers for the Radeon RX 6000 series and newer. There has also been work by Intel in preparing for Vulkan ray-tracing with Xe HPG. For when the time comes to test those implementations, there is finally one good, open-source, automated Vulkan RT benchmark so far.

  • NVIDIA Posts Patches For SVM Atomics Support With Open-Source Nouveau - Phoronix

    There are a new round of kernel patches posted today by NVIDIA for the open-source, traditionally reverse-engineered "Nouveau" graphics driver: implementing support for SVM atomic memory operations.

    NVIDIA has in the past posted Nouveau patches pertaining to Shared Virtual Memory (SVM) and Heterogeneous Memory Management (HMM). Their proprietary driver has been implementing bits of HMM and other new Linux kernel interfaces while with NVIDIA providing relevant pieces to Nouveau allows for demonstrating an open-source "client" / user of new code for satisfying upstream requirements. But Red Hat has also been actively working on improving the OpenCL/compute support for Nouveau too for some interesting reasons. So long story short, in the area of GPU compute is where NVIDIA has -- and continued -- volleying open-source patches.

  • RADV+ACO Look To Your Help For Improving The Vulkan Driver & Linux Gaming Performance

    RADV is a Vulkan driver for AMD GPUs that is part of the Mesa project and installed on most Linux distros out of the box. Our goal is to deliver a stable and performant driver to Linux gamers, and recently we've made our own shader compiler called ACO. To create the best possible experience, we'd like to take it a step further and ask our users for some testing and feedback.

Wayland Woes

  • Ubuntu 21.04 will try to use Wayland by default

    I try to use Wayland wherever possible, since the performance gains and battery life improvements are just too good to ignore. There’s still two major blockers, though – first, NVIDIA support is problematic, at best, so my main computer will remain on X until NVIDIA gets its act together.

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.
