  • i.MX8 SoC Support Is Heading Into Linux 4.21 Along With Another ARM Platform

    A few days back there was the main ARM pull request for Linux 4.21 with new SoC and board support. A second ARM pull request has been submitted now during the final moments of the 4.21 kernel merge window and it offers up some new features, most notably the initial i.MX8 SoC support.

    Developers had been aiming the i.MX8 support for Linux 4.21 after it wasn't ready the past few cycles contrary to some old plans to get it in ~4.18. But now with the pull request sent in on Friday by Olof Johansson, the support is now in place.

  • Experimental Rockchip Video Codec Linux Driver Posted

    There is an experimental Rockchip open-source video codec driver for accelerated video encode/decode posted for the Linux kernel but in its current form isn't suited for mainline inclusion.

    Randy Li of the Rockchip Linux work posted this vendor video codec support as an initial design implementation for the kernel. The driver in its current form isn't geared for being merged but rather for comparing to the status of other Rockchip video codec driver work, helping with those working on V4L2 API improvements particularly around the request API, and other open-source assistance.

  • Linux Kernel Developers Discussing Generic RGB LED Interface

    With the ever increasing usage of RGB LEDs on modern computer systems, Linux kernel developers have begun discussing a formal RGB LED user-space interface.

    To date RGB LED interface controllers supported by Linux have often exposed separate red/green/blue interfaces to user-space as separate LEDs while now there is a new discussion taking place regarding generic RGB LED support.

  • A Smackerel of Opinion: Kernel commits with "Fixes" Tag (revisited)

    Last year I wrote about kernel commits that are tagged with the "Fixes" tag. Kernel developers use the "Fixes" tag on a bug fix commit to reference an older commit that originally introduced the bug.

  • KUnit Testing Framework
  • Too much disk IO on sda in RAID10 setup

    I have a RAID10 setup with 4x 2 TB WD Red disks in my server. Although the setup works fairly well and has enough throughput there is one strange issue with that setup: /dev/sda has more utilzation/load than the other 3 disks.

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.
