Following the fire in a datacenter in France, I saw reactions on social networks such as "I've got my company in your servers", which gave me the idea of writing this article.Of course, it's not the owner of the data center who's to blame here, but accidents like this do happen, so you need to be prepared.

Double authentication, often referred to under the acronym 2FA (for 2 Factors Authentication), is the principle of requiring 2 proofs of identity from a user to connect to a site, app or service.

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...

This text was on the home page of the site, but after updating it I decided to move it to the blog? 1998 - Discovering computers At elementary school, I discovered computers.

That's all well and good, but for the sake of sound mental health, let's take a look at how to block these calls, and thus remove unhelpful distractions.

Hello, hello? Have you ever watched a child playing with "Legos"? Stacked one on top of the other, they create complex structures that are both unique and fundamentally similar, because they all share the same basic elements... What if I told you that playing with Legos is a bit like our topic for today... Welcome to the concept of object-oriented programming (OOP)! It may sound like an obscure concept, a maze of jargon designed to confuse, but fear not, it will! We're about to emba...

Hello over here 🙂, Thank you so much for clicking on this article 😁. On the last post, I told you it smelled like spring, but now it's cooled off severely 😅. Ah yes, it's true we're still not here to talk weather... I'm sorry (well, I think.). This week, we're going to play with CSS and completely break Twig, you'll see it's fun, well, it's a bit "not very clean" as a method, but hey, on this blog, I tell you all about it. Anyway, this week, we're making art...
