It's back to school time, and we're off to work on a new series of articles, starting with a closely related topic... ? Among the questions most often asked of a developer are : I've got a great idea! Are you up for doing the new Facebook? How much does a site cost? How hard is it to code?

Recently I received an email from my service provider saying "Please note that your Ubuntu version will soon no longer be supported. You should upgrade to 22.04 minimum". Well, even if this email seems nicer, I still had a feeling of déjà vu of my server getting lost in the cosmic uni...

So today we're going to take a look at the main forms that exist, and why they're useful in your apprenticeship or career as a developer?

Hello there, This week we're going to talk about what makes a good developer, but not in the way you might think. The idea for this article comes from the discussions I have with my customers and why they enjoy working with me. This article also comes from the fact that, last weekend, I was taking a look at the state of the infrastructure on which this site (and the customers) are hosted, and in two years a lot has happened.... Are you ready? Then let's get started. What this artic...
