Ah Docker! I've been hearing about it for years, but like many people (I think) I hadn't yet taken the plunge. I'd read several articles on this technology, and even looked at the official documentation to try and tweak a few things, but it was still too vague for me. First of all, what is Docker? It's (almost) magic in the sense that you don't need to worry about your server configuration, your OS or your version of PHP, Node, React ... in short. You just code on your machine, and miracu...

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...

It's a widespread practice, and understandably so: dozens or even hundreds of different passwords to remember, it's complicated. Nevertheless, you should be aware that it's a very bad practice that can one day turn against you, and as I say, prevention is better than cure. How are passwords entered on sites and applications? Before we understand why it's a bad idea to use the same password everywhere, we need to understand how and/or where your passwords are stored. What happens whe...

Hello everyone, thank you for clicking on this article! 😊 Today we're going to talk security and authentication. What is OAuth2? In life, and especially on the web, we generally authenticate ourselves with an email and a password. But this isn't always the case, especially when you need to connect to a third-party service or API. If this is your case, you'll probably come across a type of protocol called OAuth2. "What the hell is this?" If you've ever had to create AP...

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...
