  • What the Web Still Is

    Make no mistake: I feel a lot of what makes the web great is actively being dismantled, either inadvertently or deliberately. But as I mentioned earlier, cynicism is easy. My wish for next year? That all the qualities mentioned here are still present. My New Year’s resolution? To help ensure it.

  • Object detection and tracking in Python

  • How to Compare Files in Linux Using Meld (Diff/Merge) Tool

    If you are familiar with diff; a Linux terminal-based tool for comparing two files in terms of contextual differences and layout, you are going to love what Meld has to offer. Think of Meld as a diff tool with graphical upgrades.

    Whether you are dealing with Git repository files, directory files, or ordinary system files, the visual capability of Meld makes any file comparing task not only fun but also a walk in the park.

    Therefore, sorting through data and code files no longer needs to be a struggle for developers and novice Linux users. Additionally, Meld offers a merge functionality on top of it being a graphical diff tool.

  • Screen Recording in Linux With OBS and Wayland - It's FOSS

    There are tons of screen recorders available for Linux. But when it comes to supporting Wayland, almost all of them do not work.

    This is problematic because many new distribution releases are switching to Wayland display manager by default once again. And if something as basic as a screen recorder does not work, it leaves a bad experience.

    GNOME’s built-in screen recorder works but it is hidden, has no GUI and no way to configure and control the recordings. There is another tool called Kooha but it keeps on displaying a timer on the screen.

    Switching between Xorg and Wayland just for screen recording is not very convenient.

    Amidst all this, I was happy to learn that Wayland support landed in OBS Studio with version 27 release thanks to Pipewire. But even there, it’s not straightforward and hence I am going to show you the steps for screen recording on Wayland using OBS Studio.

  • 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.
