  • Learn How to Use Postman to Test APIs

    Anyone who creates APIs should also be testing APIs. One of the most popular ways to test APIs is to use Postman. Postman has over 10 million users worldwide.

    Valentin Despa created this course. Valentin is a developer educator who has been teaching software concepts for many years.

  • How to find NetworkManager version on Linux - nixCraft

    How do I check or find NetworkManager version on Linux distribution?

    We can use the nmcli command line for controlling NetworkManager and reporting network status. Another option is to use the NetworkManager to print the version on Linux.

  • [Older] Introduction to database normalization: the first three normal forms

    The table above, doesn’t satisfy the first normal form, why? For the first normal form to be satisfied, each column of a table must contain atomic (indivisible) data. In the second row of our table, which contains information about the “The Usual Suspects” movie, we can see that the genre column contains data which is not atomic. Two genres are actually listed: Thriller and Neo-noir. Let’s say in our representation we want to allow one movie to be associated with more than one genre; how do we solve the problem?

    The first thing that comes to mind may be to add a new row in the same table, repeating the information about the movie, and just specify one genre per raw. This idea is quite horrible, since we would have a lot of redundant data (we should repeat the same movie information each time we want to associate it with a new genre!).

    Another slightly better solution, would be to add a new column, so to have, for example, a genre1 and genre2 columns. This however would, among the other things, represent a limit: what if a movie should be listed under more than two genres?

  • How To Install Atom Text Editor on Manjaro 20 [Ed: The problem is that it's controlled by Microsoft]

    In this tutorial, we will show you how to install Atom Text Editor on Manjaro 20. For those of you who didn’t know, Atom is a free and open-source text and source code editor for OS X, Linux, and Windows with support for plug-ins written in Node.js, and embedded Git Control, developed by GitHub. It supports more than 35+ programming languages by default.

    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 Atom Text Editor on a Manjaro 20 (Nibia).

  • 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.
