  • How To Install Tig on Ubuntu 20.04 LTS - idroot

    In this tutorial, we will show you how to install Tig on Ubuntu 20.04 LTS. For those of you who didn’t know, Tig refers to the text mode interface for Git. It provides you with a very efficient user interface for interacting with Git. It functions mainly as a Git repository browser, but can also assist in staging changes for commit at chunk level and act as a pager for output from various Git commands.

    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 Tig on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.

  • Video Editing With Shotcut

    I recently took on a project at work which involved editing videos. I wasn't sure how to do that, or even what editor to use, but Shotcut and Avidemux were recommended to me as good programs. Both have Windows versions as well, and both are in our repo. I chose Shotcut, knowing I could use it on my work computer (Windows) and my home computer (PCLinuxOS, of course!). I also frequently take my work laptop to another office, and wanted to be able to work there as well. While working on my project, I have gotten started learning Shotcut. I won't pretend I know everything about it, but this article might get you started if you're interested. Let's explore.

  • Tutorial: Integrating OmniAuth with Sinatra Application

    As part of my GSoC project, my first task includes that user could login into their account on debci using their Debian Salsa account (collaborative development server for Debian based on the GitLab software).

    The task is officially completed using OmniAuth library and while implementing it, I found that the documentation of OmniAuth is quite a mix-match and more focused on using it with Rails app and this gives me a idea to write a tutorial for people looking to integrate OmniAuth with Sinatra application. So here it is.

    Now, depending on the provider, Omniauth requires specific strategy which are generally released individually as RubyGems. For this tutorial, I would be using omniauth-gitlab which I used for Debian Salsa in my project, omniauth-twitter and a developer strategy which could be used for project in development mode and comes with omniauth gem itself.

    For simplicity purposes, I have included all routes and OmniAuth configurations in a single file app.rb.

    Let’s start.

  • 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.
