  • How To Restore Broken Arch Linux To Previous Working State

    This brief tutorial describes how to restore broken Arch Linux and its variants like EndeavourOS, Manjaro Linux to previous working state.
    The other day, I did a full system upgrade using command "sudo pacman -Syu", and ended up with a broken Arch Linux system.

    My Arch Linux refused to boot into graphical mode, and kept displaying the error messages: "dependency failed multi-user system" and "dependency failed for graphical interface".

    The only option I had is to login to single user mode and try to rollback the updated packages to their previous versions.

    From the single user mode, I tried the following:

  • Managing files using command-line tools - Linux Concept

    Commands are names of programs installed on the system.

  • Using man pages and the help command - Linux Concept

    We could spend a good amount of time learning CentOS; it is equivalent to serving you cooked food, but in place of this, we could actually learn how to cook, so that you’ll be able to make your own different recipes. Linux has one of the best and largest bodies of documentation in the operating system for most of the commands and their options. Whether you are an experienced user or a beginner, you will never remember the exact use of all the Linux commands and utilities, each with its own multiple options. It is in this case that Linux documentation comes to our rescue.

  • Document Typeset with LaTeX and TeXstudio on Fedora – Part 1 | FOSS Linux

    LaTeX is a free and open-source software for typesetting documents. LaTeX is a preparation system for high-quality typesetting and the defacto for large technical documents, computer science, mathematics, and physics documents. TeXstudio makes it easy to edit and format LaTeX documents. You can use LaTeX to create reports, a resume, cover letters, students can present assignments or thesis, and instructors can edit presentations, syllabi, or exams.

    Technically, LaTeX is a set of macros and commands for the programming language TeX. Leslie Lamport originally wrote LaTeX to extend the functionality of the TeX typesetting engine by Donald Knuth.

    Part 1 of this article is an introduction document typesetting with LaTeX on the TeXstudio app. It will cover formatting, page layout, lists, tables, and graphics. Part 2, document typesetting with LaTeX and TeXstudio on Fedora – Part 2 will cover Math formulas, listing content and references, cross-referencing.

  • Linux apps on Chrome OS in 2021: A complete guide

    Chrome OS is incredibly powerful and versatile, running on a variety of hardware and can also run a variety of apps. In addition to running Android apps from the Play Store, it’s also possible to run full Linux apps. For many users, the basic Chromebook functionality is just fine. However, if you find yourself wanting an app or service your Chromebook doesn’t offer out of the box, Linux apps may be for you.

    What exactly can you accomplish running Linux apps? Chrome OS by default is a cloud computing platform, which leaves out some desktop-class apps you might see on a Mac or PC. For instance, if you need to run Photoshop natively, that’s not possible on your Chromebook. Video editing is also quite difficult by default on Chrome OS. Both of these problems are addressed by Linux apps.

    In addition, if you’re a developer, you undoubtedly need Linux for coding tools. While not all Chromebooks support Linux apps (there are some baseline system requirements), most modern Chromebooks will have the option available. In this guide we walk through precisely how to enable and install Linux apps on your Chromebook, and run down the best Linux apps available on Chrome OS.

  • 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.
