  • Sony Engineer Talks Up Using Flutter + Wayland For Their Embedded Interfaces - Phoronix

    A Sony engineer confirmed at this week's Embedded Linux Conference Europe that the company has begun using the Flutter toolkit atop Wayland as their means of developing user-interfaces on embedded systems.

    Hidenori Matsubayashi of Sony talked at ELCE 2020 about their evaluation of different GUI toolkits for embedded use and ultimately how they fell for Flutter and Wayland. They came to that decision when evaluating the likes of Electron, Qt, GTK, WebKit/Chromium with WebView, and the many other options out there.

    Their design requirements were needing to be able to make "beautiful" user interfaces, support easy development, exhibit low CPU and RAM requirements, work across display servers and software stacks, and the toolkit must allow use within proprietary software.

  • Linux Support Expectations For The AMD Radeon RX 6000 Series

    Lisa Su is about to begin the presentation unveiling the much anticipated Radeon RX 6000 "Big Navi" (RDNA 2) graphics cards. This article will be updated live as the event progresses but first up let's recap the current Linux open-source driver state for these forthcoming graphics cards.

    Under the codename Sienna Cichlid, the Linux support for the next-generation Navi graphics cards have been underway going back to the middle of the year. There is initial support for the next-gen hardware within the recent released Linux 5.9 kernel and Mesa 20.2. This still puts it just out-of-reach for seeing out-of-the-box support in the likes of Ubuntu 20.10 given the 5.8 kernel so the user must manually move to the newer kernel. At least with the likes of Fedora Workstation 33 there will be Linux 5.9 as a stable release update. Also important to the driver equation is needing to be using LLVM 11.0+ for the GFX10.3 back-end target and also ensuring to have the latest linux-firmware for the binary microcode files needed for GPU initialization.

    So at least going into this launch it's great there is at least open-source driver support available but not necessarily easy reach for all users right now. By the time of the spring 2021 Linux distributions like Ubuntu 21.04 there should be nice out-of-the-box support for those wanting good support without any hassles. Or if you are on an enterprise distribution like RHEL/CentOS or SUSE Linux Enterprise or Ubuntu 20.04 LTS, AMD should be providing their usual Radeon Software for Linux packaged driver that ships updated user and kernel-space components for deploying their driver that way.

  • Mesa 20.3 Supports Intel Alder Lake Gen12 Graphics - Phoronix

    Last week Intel open-source engineers began publishing Linux kernel patches for the "Alder Lake S" graphics support. That work should be found in the Linux 5.11 cycle being christened as stable in early 2021. In user-space, Alder Lake graphics patches also appeared for their OpenCL / oneAPI Level Zero compute stack and now merged into Mesa 20.3 as well for OpenGL / Vulkan support.

    Given that Alder Lake is using Intel Xe "Gen12" graphics as found already for Tiger Lake and Rocket Lake, the actual driver-side enablement is quite minimal thanks to employing the existing code paths. The Alder Lake "ADL-S" support was merged into Mesa on Tuesday and is just 20 lines of new code. That consists of just adding the new PCI IDs and then the family bits for the Alder Lake family and indicating they make use of Gen12 features.

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.
