  • The Networking Changes For Linux 5.17 Are Very Exciting - Phoronix

    The Linux networking subsystem updates for the in-development 5.17 kernel are quite exciting as usual given how prolific Linux is from large servers in the cloud to running on enterprise networking gear down to Linux on small IoT hardware. Not only is there a lot of hardware driver action as usual but also some key performance/latency optimizations. 

    On the performance optimization front, there is a significant latency optimization for AF_UNIX sockets. 

  • Linux 5.17 EDAC Driver Brings Support For New AMD Zen CPUs, RDDR5 / LRDDR5 Memory - Phoronix

    With the Linux 5.17 kernel merge window formally open today, among the early pull requests sent out this morning were the Error Detection And Correction (EDAC) driver updates which is notable this time in preparation for next-generation AMD EPYC server hardware.

    The most exciting EDAC work for this next kernel cycle is preparation for next-generation AMD Zen processors as well as adding support for DDR5 system memory to this kernel code that deals with ECC and other error detection/correction handling. The DDR5 support within the scope of EDAC is both for Registered DDR5 and Load-Reduced DDR5 memory. This EDAC work I previously reported on last month while the news today is that it's been submitted for debuting in Linux 5.17.

  • The Intel/AMD Laptop & Tablet Support Improvements For Linux 5.17 - Phoronix

    The x86 platform drivers area of the kernel remains very active in recent times thanks to the continued investments by Red Hat as well as growing IHV interest from the likes of Lenovo while also still having many contributions flow in from the likes of AMD and Intel. With Linux 5.17 are a number of driver additions and improvements for benefiting various x86 laptops and tablets.

  • USI Stylus, LetSketch Tablet Driver, Better Apple Magic Device Support In Linux 5.17 - Phoronix

    The HID subsystem changes are rather exciting this time around of the new feature material for Linux 5.17.

    First up, there is USI stylus/pen support with Linux 5.17. USI is the Universal Stylus Initiative for supported styluses/pens that would work across devices supporting the standard. Google has been backing USI for Chromebooks and other major IHVs/ISVs have been backing USI for much more convenient stylus support across devices. Intel worked out the USI standards support for the Linux kernel.

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.
