  • The Art of (Not) Painting Pixels – GNOME Shell & Mutter

    Being a compositor and a compositing window manager, the most important aspect Mutter and GNOME Shell is to paint pixels to your monitors with relevant content. A large part of this content is provided by applications themselves, but many elements still need to be rendered on top of them.

    Over the past few years, Mutter’s codebase has slowly but steadily been refactored, cleaned up, reorganized, and modernized. This includes the internal copies of Clutter and Cogl. With the beginning of the GNOME 40 development cycle, it all converged in a specially large and exciting set of changes which we’ll be talking about in this article.

  • GSoD Weekly Summary 5

    Before starting this week, I created an issue mentioning all the issues that I found and started completing them one by one while I kept adding new ones when required. So now the second task was to look again for the next issue which I found under “Using the Keyboard” there was a link missing which I added in the documentation.

    After this, the next task was to fix the subscript and superscript page style and add a link to it too. These changes I included with my previous PR.

  • Canonical Drops etcd for Dqlite For MicroK8s

    MicroK8s is a lightweight and easy to use Kubernetes distribution designed to run in resource-constrained environments such as IoT and edge devices. As Canonical is eyeing enterprise use-cases it’s making Microk8s more resilient by adding high availability capabilities to it.

    Microk8s already has the clustering feature; with a single command, users can join multiple MicroK8s nodes in a cluster. With HA, as soon as users join three or more nodes, they get the Kubernetes control plane distributed across these nodes. If they join more nodes they get all the API services of Kubernetes available on all nodes and the control plane is still distributed on these nodes.

  • 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.
