New week, new article! How are you? The wife? The kids? The goldfish? (is the goldfish important?) This week we're going to try and figure out what the padlock in your browser's address bar means, so yes on this site there is one (there, I've just saved you the trouble of looking up to check).

Last time, I told you about CI/CD right here I don't know if you thought it was cool, but today we're going to talk about Git itself. "You've already explained to us, though, that it's meant to deploy our code online, is there anything else?" Yes, CI/CD is only part of what Git can be used for. Indeed, its primary use is versioning. Behind this rather barbaric name lies something that is both very useful and almost magical. Yes, it is. "What's this guy trying to sell us now? Noth...

Today we're going to be talking about one of the most important topics on the web, yet one that is all too often overlooked by many. That subject is Responsive Design. "What's this thing you're doing? Just another gimmick to look good? To look good, yes, but it's anything but a gimmick? It's about adapting the size of your website to all screen formats. From a smartphone to a TV or even an overhead projector. Why is this important? Which device do you think is most often used to acce...

Ah, updates! You must see dozens of them every day. It's time-consuming, it's inconvenient, if they're launched when you're busy (hello Windows?). But then... Yes. But it's important. An update is never done by chance, and its main purpose is to correct bugs and, above all, security flaws. "What do you mean? You're developers and you don't code properly? " It's a little more complicated than that. Indeed, even if the error remains human, flaws generally occur AFTER a product has bee...

Hello ?, This week's article is based on something that happened to me recently. During an Ubuntu server update, it seems that the bind9 package, after the update, started to crash after a while. The problem is that on this machine, I need DNS resolution, as it hosts services that need to complicate with other online services like Stripe. So I end up with a call informing me that when it comes to entering the bank card on this Symfony application, well, it doesn't display the form reques...

Hello and thank you for clicking on this article 😁 Today we're going to talk about experimental code that I've been interested in recently. To contextualize, I finished a PHP course for a promo I had as a trainer. Once we'd seen the basics and got to the end of the program, we naturally moved on to the MVC and object-oriented aspects of implementing a project in native PHP. It was at this point that I asked myself the question of how to implement a router in a project of this t...

Without realizing it, you use them every day. For example, on your packages ordered online, there are labels. These self-adhesive labels are created using a label printer.
