  • How to Install/Upgrade GIT on Ubuntu 22.04 LTS - LinuxCapable

    GIT is a free and open-source version control system that can efficiently manage small projects or huge ones. It enables multiple developers to work together on nonlinear development, as it tracks changes in source code for each branch of our project’s history. Hence, we never lose anything by going back through old stages if something goes wrong!

    In the following tutorial, you will learn how to install the latest or upgrade GIT on Ubuntu 22.04 Jammy Jellyfish using the GIT Maintainers PPA.

  • Dark window decorations for st and Emacs

    Since a few weeks, I’m a new happy user of the Pantheon desktop environment (built by the community behind Elementary OS[1]). Thus, I moved from i3 and a border-less tiling window manager to a more classical floating window manager. After many years of using a tiling manager, I realized I never make full use of them: I only have an heavy usage of virtual desktop, with one maximized window on each desktop. My three main applications are Firefox[2], GNU Emacs[3] and simple terminal[4] with tmux[5] embedded. Emacs and Tmux already gives me a powerfull in-app windowing system and websites are more and more designed for wide screens. That is why, in the end, any window manager works for me, as soon as they allow me to maximize a window.

    Pantheon desktop is built on the same root as the Gnome desktop and use recent GTK version behind the scenes. We now have the ability to use a unique theme through the whole desktop, but select between dark and light variant on a per application basis. This is already supported by a lot of Gnome or Elementary applications, but it is a bit more complicated for other apps.

    What become very annoying is when you use a dark application, which keeps light window border, because that application does not know how to tell to the window manager that it prefer a dark theme. That was my case with both GNU Emacs and simple terminal. In both of them I use the Dracula dark theme[6], and thus having light window borders was a bit sad.

  • How to Install Sublime Text 4 on Ubuntu 22.04 LTS - LinuxCapable

    Sublime Text 4 is an excellent choice as your go-to program to edit code. Sublime is known for its speed, ease of use, cross-platform, and community contribution. It natively supports many programming languages and markup tongues, but users can also expand its functionality with plugins!

  • How to Install/Connect PuTTY SSH Client on Ubuntu 22.04 LTS - LinuxCapable

    PuTTy is an open-source, lightweight program that you can use to login into your remote machine with a terminal emulator that has been around since 2002.

  • Install Brave Browser on Ubuntu 22.04 LTS Jammy JellyFish - Linux Shout

    Brave was launched in 2016 by Brendan Eich, co-founder of Mozilla and JavaScript. Brave aims to make the web a better place, and its primary concern is privacy and security. Here we learn the steps to install Brave browser on Ubuntu 22.04 LTS Jammy JellyFish using the command terminal.

    Brave is a popular browser yet still behind Google Chrome even it offers more features. This browser keeps trying to position itself as a “safer and faster web browser ” against other similar software providers. To make itself apart from other browsers, Brave has an integrated ad blocker called “Brave Shields”. The interesting thing is it is also based on Chromium, i.e. based on the open-source code of Google Chrome, and is therefore not a completely new invention of the browser.

  • How to screen share with the Linux KDE Plasma Desktop | Opensource.com

    If you've ever done remote support professionally or out of familial obligation, then you've been on a call where solving problems are only secondary to the impossible task of visualizing what's actually on your user's screen. How many times have you described complex desktop tasks only to later realize that your user hasn't even turned their computer on yet? Support is important, but the frustration is real, and it's a shared experience for both the people in need of support and the people who graciously try to provide it. I believe it's important for people to perform tasks themselves as a way to learn a new skill, but there's also an argument for observing the way it's meant to be done by an expert. That's what screen sharing is for, and the KDE Plasma Desktop has it built-in.

  • How to Change the Output Color of Echo in Linux

    In UNIX-like operating systems, the echo command is used to display a string of characters onto the terminal.

    Usually, the color of output of the echo command follows the terminal theme, nothing unusual about that.

    But if you want, you can change the color of the output text of the echo command in Linux.

    Why would you want to do that? There could be several reasons for that. For examples, if you are writing a script that has a step where it needs to warn the user, using red colored output could be useful.

  • How To Install GCC Compiler on AlmaLinux 8 - idroot

    In this tutorial, we will show you how to install GCC Compiler on AlmaLinux 8. For those of you who didn’t know, The GNU Compiler Collection, commonly known as (GCC), is a software package with compilers and development tools for several programming languages such as C, C++, Objective-C, Fortran, Java, and many more. It is free and open-source software, which means that everyone has the opportunity to contribute or modify the application according to their own needs.

    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 through the step-by-step installation of the GCC Compiler on an AlmaLinux 8. You can follow the same instructions for CentOS and Rocky Linux.

  • Scan documents and old photos on Linux with Skanlite | Opensource.com

    Although the world has mostly gone digital now, there are still times when you just have to print a form, sign it, and scan it back in. Sometimes, I find that a snapshot on my phone suffices, but some industries require a better copy than a hasty snapshot, and so a flatbed scanner is necessary. The KDE project provides an application called Skanlite that helps you import documents scanned on a flatbed, or even a tethered camera.

  • 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.

  • 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.
