  • Intel Has A Number Of WiFi Improvements Ready For Linux 5.17 - Phoronix

    Intel's modern WiFi driver "IWLWIFI" is set to see a number of improvements with the Linux 5.17 kernel development cycle kicking off in January.

    Merged to the networking subsystem's net-next branch ahead of the Linux 5.17 merge window in mid-January were a number of improvements for new and existing wireless hardware. Some of the Intel WiFi improvements coming for the Linux 5.17 kernel include:

    - Continued work enabling their next-generation "Bz" hardware family. Going back to the summer Intel was working on Linux support for yet-to-be-released "Bz" WiFi hardware and that enablement work is continuing for Linux 5.17. There are also Rx changes for new hardware families.

  • Sound Open Firmware 2.0 Released For The Intel-Led Open-Source DSP Stack - Phoronix

    It was nearly four years ago already that Intel announced Sound Open Firmware in pushing for open-source sound firmware for their hardware. The Sound Open Firmware effort has been a great success even if it's not a shiny project widely talked about among consumers. Just prior to the holidays Sound Open Firmware 2.0 was quietly released.

    The Sound Open Firmware project provides an open-source digital signal processing (DSP) firmware stack and software development kit around it as well as open-source emulation support with QEMU, etc. Beyond the firmware itself the Linux kernel has the Sound Open Firmware host driver support and the SOF driver stack is dual-licensed under both the BSD and GPL. More details on the SOF project can be found via the project documentation.

  • Linux Kernel Preparing Support For A More Practical Virtual M68k Machine - Phoronix

    When it comes to the Motorola 68000 "m68k" virtual machine targets, the most powerful option under Linux right now is the Quadra 800. That though for virtualization purposes isn't too useful by today's standards with being limited to 1GB of RAM and limited interface support. But a new Virtual M68k Machine aims to provide a more useful target and support has already landed in QEMU while the Linux kernel support is pending.

    The new Virtual M68k Machine is based on Google's Goldfish interfaces used for the Android simulator and reuses some of that Goldfish code for this more relevant M68k machine.

  • AMDVLK 2021.Q4.3 Released To Fix Poor Wayland Performance - Phoronix

    AMD's official Vulkan driver team is ending out the year by pushing out AMDVLK 2021.Q4.3 as their official open-source Radeon Vulkan driver implementation for Linux systems. This alternative to the Mesa RADV driver finally has fixed up its very poor performance for Vulkan under Wayland. 

    AMDVLK 2021.Q4.3 was released this morning as their latest routine code drop accompanied by binaries for RHEL/CentOS 7 and 8 and Ubuntu LTS releases. It's been three weeks since the last AMDVLK code drop while this end-of-year release has just a few changes but rather notable.

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.
