  • Fixing toolbox due to glibc 2.34 changes

    glibc 2.34 has moved pthreads functions from libpthread to libc and toolbox has started to fail in rawhide builds due to this change.

    The root of this problem is that toolbox need to bind mount itself inside the container to initialize it, so we need the same executable file from the host to work on different containers.

  • How to Read, Write & Parse JSON in Python – TecAdmin

    JavaScript Object Notation aka JSON is a very lightweight standard data representation format. It is used for storing and transporting data. It was derived from Javascript but is now language-independent. It was created with the intention of making a text-based interchange format that is easily readable by humans.

    JSON is compatible with most programming languages and can easily be integrated as they have built-in functionalities to read, write and parse JSON.

    JSON is commonly used across the computing world for APIs and for Config files of different programs such as games. It is also used to transfer data from a server to the client and vice versa.

    In this post, we will go through a guide on how to read, write and parse JSON in python. Python has a built-in package named JSON which can be used to manipulate JSON data.

  • 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.
