  • A Lesson in LoRa Module P2P Standards (or the Lack Thereof)

    I got a handful of LoRa modules from Reyax a while back, the RYLR896 model based on Semtech SX1276 chips. Instead of using an SPI interface they operate over UART using a small set of AT commands. This made them easier to work with since I didn't have to dig too deeply into a bunch of SPI registers and Semtech specs and they communicate between one another really well. My Espruino JS module for them is available here, which I've used in a few of my YouTube videos.

  • Coding the Classic Snake Game with Python Turtle Graphics

  • Django + AJAX : How to use AJAX in Django Templates

    AJAX or Asynchronous JavaScript And XML is a set of web development techniques using web technologies on the client-side to create asynchronous web requests.

    In simpler words, AJAX allows web pages to be updated asynchronously by exchanging data with a web server behind the scenes. This means that updating parts of a web page is possible, without reloading the whole page.

    We can make AJAX requests from Django templates using JQuery. With the jQuery AJAX methods, you can request text, HTML, XML, or JSON from a remote server using both HTTP Get and HTTP Post and you can load the external data directly into the selected HTML elements of your web page.

    In this tutorial, we will learn how to make AJAX HTTP GET and POST requests from Django templates.

  • 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.
