  • X.Org Reins In Their Cloud Costs, Switches Public Clouds

    Last year we wrote how the X.Org/ cloud hosting costs were getting out of control so much so that they would either need to start finding sponsors and/or cut the continuous integration (CI) services offered to the hosted open-source projects, among other measures, as the costs were ballooning greatly. Thanks to a number of improvements to their hosting configuration, that is becoming a more manageable amount.

    Last year after they came to the realization how their cloud costs were getting out of control, they did make a number of improvements to tune their configuration in order to reduce costs. With that initial round of optimizations they went last year from spending around $6k USD on monthly cloud costs to around $3k and then continued their optimizations and other ways to spend less on the cloud.

  • QEMU Support For Rendering Vulkan Software On The Hosts GPU In Virtual Machines Using Virgil 3D Is Underway - LinuxReviews

    It is currently possible to run OpenGL applications in virtual Linux machines in QEMU and have the rendering done on the host machines GPU. It works, and it is faster than software rendering within the virtual machine, but it is not blazing fast. It will eventually be possible to render Vulkan software the exact same way.

  • Zink: Running OpenGL on top of Vulkan - Interview with Mike Blumenkrantz - Boiling Steam

    This time we have the pleasure to discuss Zink with one of his key contributors, Michael Blumenkrantz. What is Zink, you may wonder? Zink is a project somewhat similar to DXVK in concept, where you take calls from one API language and you translate them to Vulkan instructions. For DXVK, it’s DirectX 9,10 and 11. For Zink, we are talking about OpenGL.

    Now, why support OpenGL through Vulkan? After all, OpenGL drivers are typically available on Linux, and most hardware should properly support it. Well this is your lucky day, as Mike will provide a full perspective about the Zink project and what it can be used for.

    Since this interview was conducted in mid January 2021, a few things have changed since them, the most relevant one being that GL 4.6 and GLES 3.1 support was already merged into Zink in the meantime.

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.
