  • Linux 5.7 DRM Bringing New "TIDSS" Driver

    The first batch of DRM-Misc changes following the recent Linux 5.6 merge window have been merged into DRM-Next in forming the early material that will ultimately come to the Linux 5.7 cycle in April.

    With this first batch of new feature material there are changes like the Arm Mali 400/450 "Lima" driver now supporting heap buffers, various DRM core improvements, DPMS clean-ups of atomic drivers, other maintenance items, and a new Direct Rendering Manager driver.

  • Intel Ethernet E823 Support Coming To The ICE Driver In Linux 5.7

    Intel's ICE driver for the Ethernet E800 series is seeing a new member of the family come Linux 5.7.

    Queued in net-next thanks to an Intel developer is adding support for Intel Ethernet E823 series devices. This Intel E823 support for the Linux ethernet driver covers E823-L and E823-C adapters.

  • Linux EFI Going Through Spring Cleaning Before RISC-V Support Lands

    The Linux EFI boot code is going through some "spring cleaning" ahead of the RISC-V EFI support landing that still could make it for the Linux 5.7 kernel cycle this spring.

    The EFI kernel code is seeing some cleaning before the RISC-V support is merged since that increases the complexity of the code-base and for testing due to having an extra architecture in there. With this early batch of EFI changes to be staged until the Linux 5.7 merge window in April, the RISC-V support isn't yet included but it still could get pulled together in the next month for making the 5.7 kernel.

  • Linux NUMA Patches Aim To Reduce Overhead, Avoid Unnecessary Migrations

    A set of patches that continue to be worked on for the Linux kernek is reconciling NUMA balancing decisions with the load balancer. Ultimately this series is about reducing unnecessary task and page migrations and other NUMA balancing overhead.

    The main focus with the patch series is addressing inconsistencies between the kernel's NUMA balancing code and the load balancer. "The NUMA balancer makes placement decisions on tasks that partially take the load balancer into account and vice versa but there are inconsistencies. This can result in placement decisions that override each other leading to unnecessary migrations -- both task placement and page placement. This series reconciles many of the decisions -- partially Vincent's work with some fixes and optimisations on top to merge our two series."

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.
