  • How to record your Linux desktop in Wayland

    Wayland is a new desktop protocol for Linux desktops. It has been in development for quite a while, and it is a modern alternative to the most used desktop protocol on Linux: X11 Server.

    Wayland has tons of excellent modern features, however, a lot of apps still rely on the old X11 ways of doing things. As a result, users using Wayland might be frustrated in trying to do things that come easy on X11 desktops.

    One such thing that is easy to do on X11 but tough to accomplish on Wayland is screen recording. Thankfully, Blue Recorder exists and makes recording Wayland desktops a little easier.

  • Install the latest version of the Docker engine to avoid vulnerabilities - TechRepublic

    Ubuntu is a great Linux for numerous purposes. For the desktop, for servers, for production, for operations, for development and for deploying Docker containers. But there's one thing you must know about Ubuntu. Although it's a rock-solid, incredibly user-friendly operating system, the available software isn't always the latest-greatest. You might even find, in some instances, that software is a few releases behind. Why? Because the developers want to ensure your experience is always the best it can be.

    Take, for instance, my Pop!_OS (based on Ubuntu 21.04) version of Docker is 20.10.2. The most recent Docker release, however, is 20.10.7 (released June 6, 2021). Now that point release may or may not contain bold new features, but it will certainly include bug fixes and various patches. In certain circumstances, it might behoove you to always have the latest version of Docker installed (especially given the mercurial nature of container security.

  • Automate performance metrics collection and visualization with RHEL System Roles

    One of the main challenges that system administrators, developers, and others face when running workloads on Red Hat Enterprise Linux (RHEL) is how to optimize performance by properly sizing systems, understanding utilization, and addressing issues that arise. In order to make data-driven decisions about these topics, performance metrics must be recorded and accessible by the administrator or developer.

    Performance metric tracking with Performance Co-Pilot (PCP) and Grafana can be useful in almost any RHEL environment. However, the process to get it set up across a large number of hosts might seem daunting at first. This is why Red Hat introduced a Metrics System Role, which automates the configuration of performance metrics. I’ll show you how in this post.

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.

  • 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.
