  • More NIR Optimizations En Route, "Soft FP64" Still Being Worked On

    When it comes to letdowns for Mesa in 2018, sadly OpenGL 4.6 support didn't reach mainline. Another unfortunate feature not making it into the Mesa 18.x release series is the "soft FP64" support to allow some older GPUs to work with OpenGL 4.x. While we haven't seen any new soft FP64 patches in a while, not all hope is lost.

    It's been a while since any exciting soft FP64 work was presented, but this work is notable in it will let AMD Evergreen GPUs expose OpenGL 4.3 with the open-source driver stack. This FP64 emulation support will also help out older Intel and NVIDIA (via Nouveau) GPUs as well that lack native hardware double precision floating point capabilities.

  • More DRM Changes Queued Ahead Of Linux 4.21

    Another batch of drm-misc-next changes has been staged ahead of the Linux 4.21 kernel merge window that will open at the end of December or early January.

    This latest round of drm-misc-next code includes more core changes as well as changes to the smaller Direct Rendering Manager drivers that don't otherwise send in their own pull requests direct to DRM-Next.

  • Mozilla VR Blog: Updating the WebXR Viewer for iOS 12 / ARKit 2.0

    Last year, we created an experimental version of an API for WebXR and built the WebXR Viewer iOS app to allow ourselves and others to experiment with WebXR on iOS using ARKit. In the near future, the WebXR Device API will be finalized and implementations will be begin to appear; we're already working on a new Javascript library that allows the WebXR Viewer to expose the new API, and expect to ship an update with the official API shortly after the webxr polyfill is updated to match the final API.

    We recently released an update to the WebXR Viewer that that fixes some small bugs and updates the app to iOS 12 and ARKit 2.0 (we haven't exposed all of ARKit 2.0 yet, but expect to over the next coming months). Beyond just bug fixes, two features of the new app highlight interesting questions for WebXR related to privacy, friction and platform independence.

    First, Web browsers can decrease friction for users moving from one AR experience to another by managing the underlying platform efficiently and not shutting it down completely between sessions, but care needs to be taken to not to expose data to applications that might surprise users.

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.
