  • Get started with edge computing by programming embedded systems |

    RTOS is an open source operating system for embedded devices developed by RT-Thread. It provides a standardized, friendly foundation for developers to program a variety of devices and includes a large number of useful libraries and toolkits to make the process easier.

    Like Linux, RTOS uses a modular approach, which makes it easy to extend. Packages enable developers to use RTOS for any device they want to target. One of RTOS's most popular extensions is the AT device package, which includes porting files and sample code for different AT devices (i.e., modems).

  • 15 Quick Git Commands with Examples in Linux

    Git is an open-source distributed version control system and it’s free to use under GNU General Public License Version 2. In today’s context, everyone in software development uses it from small to very large projects because it keeps track of our source code history which adds more flexibility to projects. It’s usually used by developers in the software development process collaborating with the team as it has full control over version tracking of any set of files. Git was developed by Linus Torvalds with the intention of support for distributed, non-linear workflows, the minimal number of complexities, data integrity, and flexibility in the software development.

  • 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.
