  • A good, solid Linux kernel, and more industry trends

    The impact: Linux kernel development is a never-ending series of itches getting scratched. Sometimes those are big, widely felt itches, sometimes they're more niche or targetted ones, but the progress and the process never ceases to amaze me.

  • RadeonSI Gallium3D Adds Support for EGL Protected Surfaces Using AMDGPU TMZ [Ed: More DRM in Linux -- a kernel that now works to prevent you doing what you want on your very own PC]

    This year AMD has been working on the likes of TMZ as well as HDCP support for handling DRM'ed/encrypted content on Linux. This work appears to be mainly driven by AMD APUs beginning to appear in Google Chromebooks and ensuring copy-protected content can play properly, etc. For most users EGL_EXT_protected_surface will go unused but at least the capability is there for those who want it.

  • Setting Up the ARM32 Architecture, part 1

    After we have considered how the ARM32 kernel uncompressed and the early start-up when the kernel jumps from executing in physical memory to executing in virtual memory we now want to see what happens next all the way until the kernel sets up the proper page tables and starts executing from properly paged virtual memory.

    To provide a specific piece of the story that does not fit into this linear explanation of things, i have also posted a separate article on how the ARM32 page tables work. This will be referenced in the text where you might need to recapture that part.

  • Reiser4 + Reiser5 File-Systems Updated For Linux 5.9 Support - Phoronix

    For any of you that happen to still be relying on the out-of-tree Reiser4 file-system or interested in the technical design of Reiser5, these file-system drivers have been updated for Linux 5.9 compatibility.

    Edward Shishkin continues with Reiser file-system development and spent a portion of his Sunday getting out updated patches for applying Reiser4/Reiser5 support against upstream Linux 5.9.

    The v5-unstable patches have been updated against Linux 5.9.2 and in the process also adds optimized operations on striped extents to deliver a data migration speed-up. There are also other changes as a result of the re-base.

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.
