  • State Machines in Qt 6.2

    State machines are abstract computational machines that can be in only one of their finite number of states at any given time. They can change from one state to another in response to inputs. State machines can be defined by the list of their states, their initial state and the inputs that trigger the state transitions.

  • Time to Say Goodbye: Python 3.6 Is End-of-Life

    Why? Because it will no longer receive either bug or security fixes. What does that mean? It means if you’re using Python 3.6 past this month, you do so at your own risk.

    Trust me when I say you do not want that. This is especially so with the recent discovery of the Log4j vulnerability. No, that doesn’t directly involve Python, but it makes a very loud and painful case for always staying up to date.

    That’s a problem. Consider this: As of Dec. 16, 2021, at least 17.39% of packages that were downloaded from PyPI were based on Python 3.6. And that’s knowing this version of Python was about to reach end of life.

  • 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.
