  • Intel Has Been Quietly Developing A New Backend Compiler For Their OpenGL/Vulkan Drivers

    One of the interesting reveals so far from this week's X.Org Developers' Conference in Montreal is that Intel has been developing a new back-end compiler for their OpenGL/Vulkan Linux drivers based upon their experiences so far with their NIR support and the lessons learned over the past number of years.

    While Valve has been developing ACO as a new Radeon compiler back-end, Intel developers have been creating "IBC" as the new "Intel Backend Compiler" for their Iris OpenGL and ANV Vulkan driver components living within Mesa.

  • The Matrix Of Software Projects Mapping Khronos APIs From DXVK To Zink & CLVK

    Neil Trevett, the president of the Khronos Group, presented at the X.Org Developers' Conference for the first time. During his presentation on Wednesday he covered their usual initiatives, how Khronos engages in open-source and open standards, and related bits -- plus a few interesting ones.

    For the most part the presentation isn't really dramatic for any veteran developer or anyone reading Phoronix for enough years. Though he did re-affirm the commitment that "open-source is vital to build ecosystems around open API standards" -- yes, many of you will find that ironic with Trevett being employed by NVIDIA. On the Khronos front, they have continued engaging and pushing forward their conformance test suites (CTS) as open-source and that's been one of the exciting developments of recent years and ensuring better quality drivers.

  • Why HDCP support in Weston is a good thing

    First I'll reiterate what HDCP is and why supporting it cannot take away any freedoms. Then I'll give some background on Weston's ideology and justify supporting HDCP in Weston with both economical and technical arguments. While I do work for Collabora, these are my personal opinions.

    [...]

    I was not participating in the project yet when the license was chosen, but I agree with it. I, with my upstream Weston maintainer hat on, want Weston to be used by companies, including in their shipping products. MIT license makes that very easy for the companies. GNU GPL or LGPL could make it hard, especially GPL v3+ which many companies just steer very clear of. This is the reality outside of our control, however sad you might think it is. Forced with a trade-off not unique to the Weston project, it chose to favour adoption over strong copyleft, as did other open source projects before, Xorg and Mesa for example.

    When Weston is used in shipping products, it is much more likely that companies will provide resources to improve Weston also in upstream. Even if companies did not directly do that, they might hire others like Collabora to work on Weston, and then Collabora can redirect some of that revenue back to Weston upstream development. That will likely benefit also other users of Weston, even the private home users and hobbyists. It is all the same reasons why hardware drivers should go into the Linux kernel upstream, just in much smaller scale.

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.
