The what? What's this now? No, I'm sure you've already heard of it. 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. So here's a scoop: you've all used this before, and for a very long time. And yes, when you withdraw money from a cash dispenser (or make a contact payment with your bank card), it's 2FA.

Hello there, This week we're going to be talking about image formats. In fact, this article follows on from my article on CSS, and we're going to be talking about optimizing sits, in this case images. First of all, we'll review the older image formats, find out how to optimize them and finally talk about WEBP. We'll even see how it's possible to have a site or application that uses this format automatically, as is the case on the site you're currently visiting. Other image formats We'...

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...

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...

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. At the time, Windows 95 was the star product, and I fell in love with these machines.

At the same time, I got an Amstrad CPC equipped with BASIC, which marked the beginning of...

Well, happy new year! Admittedly, I'm a little late in wishing you a happy new year, but January is always the month for getting back into the swing of things, planning for the year and getting back in touch with just about everyone. Not to mention the galettes ... anyway 😛 Today I wanted to talk about a handy little tool that appeared on iOS 14: widgets. Personally, I use them a lot for apps that give me info at a glance like the weather, the day's to-do list, the calendar, et...

Hello, hello?. This week, we're going to talk about a subject that bothers us all. We've all received at least one in our lives, and for some of us (like me, for example), it's easily 10 or so a day. 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. If the line belongs to a company If the phone line belongs to a company, that company has fewer options for blocking these calls, sin...
