    Under CEO Arvind Krishna, IBM is in the midst of the biggest transformation in its 109-year history, doubling down on the hybrid cloud and artificial intelligence.

  • Shifting left: Davie Street Enterprises implements DevSecOps [Ed: Countless buzzwords here: "DevSecOops", "DevOops", "Clown", "solution", "Ecosystem", "culture"...]

    Davie Street Enterprises (DSE) continues its digital transformation journey. After transforming the culture, standardizing and automating the IT infrastructure, deploying a middleware strategy, and deploying its cloud strategy, DSE is beginning to shift towards DevOps. This is where DSE can leverage the cultural changes implemented within its development and operations teams to release features faster than the competition, using container technology.

  • New systemd 248 feature 'extension images' updates immutable file systems without really updating them

    Version 248 of systemd, a widely used system and service manager for Linux, adds a feature called system extension images, designed to allow system files to be added, or appear to be added, even on read-only file systems.

    As developer Lennart Poettering explained: "When a system extension image is activated, its /usr/ and /opt/ hierarchies and os-release information are combined via overlayfs with the file system hierarchy of the host OS."

    The primary use case for system extension images is for immutable operating systems like Red Hat's Silverblue and Kinoite. In these OSes, the file system is read-only and is updated by replacing it with a new image rather than being patched, which is better both for security and stability.

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.

  • 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.
