  • Red Hat takes Kubernetes to the cloud's edge

    Arpit Joshipura, The Linux Foundation's general manager of networking, predicted "edge computing will overtake cloud computing" by 2025. IBM Services Global CTO and Vice President Bridget Karlin won't go that far but said: "We will see an increase in edge computing due to the sheer quantity of instances compared to centralized cloud centers." How many? IDC forecasts that by 2025 there will be 55.9 billion connected devices. Leading Linux and cloud company Red Hat will be ready.

  • Get your choice of Linux distribution on IBM LinuxONE

    When you first learn about IBM LinuxONE, many of the resources talk about security, resiliency, open source, and innovation. These benefits have been covered extensively. But on a practical level, what distribution of Linux does LinuxONE actually run?

    First, let’s back up for a moment. From a Linux perspective, LinuxONE is a mainframe (like its sister IBM Z, often referred to as the s390x architecture in the open source world) that IBM has developed to exclusively run Linux. This is enforced through specific Integrated Facility for Linux (IFL) processors that only run Linux, and do not run some of your more traditional mainframe operating systems, like z/OS. From there, you can run Linux directly on a Logical Partition (LPAR) from the Processor Resource/System Manager (PR/SM) or, more commonly, on z/VM or KVM. Once that decision is made, you can install Linux.

  • Libre/Open-Source POWER10 Hardware Systems Unlikely Until At Least 2022

    While Raptor Computing Systems has been making fabulous 100% open-source/libre hardware systems based around POWER9 with the likes of their Talos II and Blackbird systems, don't hold your breath on quickly seeing fully-open POWER10 systems even with "OpenPOWER" being trumpeted in recent years and similar for being more open-source friendly than the likes of Intel and AMD.

    IBM today announced POWER10 for shipping in H2'2021. But as mentioned in that article, seeing "libre" POWER10 hardware might not come so quickly. Unfortunately that was confirmed this morning by Raptor that any POWER10 platforms from them will not come until at least 2022.

  • vDPA Kernel Framework Part #1: vDPA Bus for Abstracting Hardware

    In the previous post, we provided a high level overview of the kernel vDPA framework solution. Starting with this post and for the posts, we will dive into the technical details of the architecture and use cases for the kernel vDPA framework interacting with containers and VMs.

    The audience of these technical articles are those who really want to understand the logic and details behind the vDPA kernel design. For those who only want to focus on the high level solution we recommend sticking to the previous post

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.
