  • IBM Linux-only mainframe delivers breakthrough security
  • Kubernetes Meets HPC

    Anyone who has worked with Docker can appreciate the enormous gains in efficiency achievable with containers. While Kubernetes excels at orchestrating containers, high-performance computing applications can be tricky to deploy on Kubernetes.

    In this post, I discuss some of the challenges of running HPC workloads with Kubernetes, explain how organizations approach these challenges today, and suggest an approach for supporting mixed workloads on a shared Kubernetes cluster. We will also provide information and links to a case study on a customer, IHME, showing how Kubernetes is extended to service their HPC workloads seamlessly while retaining scalability and interfaces familiar to HPC users.

  • WordPress to ditch React library over Facebook patent clause risk

    Automattic, the company behind the popular open source web publishing software WordPress, has said it will be pulling away from using Facebook’s React JavaScript library over concerns about a patent clause in Facebook’s open source license.

    In a blog post explaining the decision yesterday, WordPress’ Matt Mullenweg said Automattic had hoped to officially adopt React for WordPress — noting it has already used it for the Calypso ground-up rewrite of WordPress.com a few years ago, and had started using it for its major Gutenberg core project.

    But he reveals it’s changed its mind after seeing Facebook dig in behind the patent clause — which was recently added to the Apache Software Foundation’s (ASF) list of disallowed licenses.

  • 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.
