Hello, hello 🙂. Thanks for clicking on this article 😁, for the record, it will be less condensed than the last one, this week, we're going softer 😛. Basically, I'm not familiar with Powershell, I'm more in the world of penguins and all that... but a few months ago, I had to work with Powershell ... and Linux. Today, I'd like to tell you a little about my experience of this adventure, take this article as a little story from a guy who didn't know Powershell, but...

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...

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). Naaaaaa but don't go away, it's an interesting subject! promise?. Before you start I'm redirecting you to the "asymmetric encryption" paragraph of my article on ransomware, because there's no p...

Hello, good morning 😁, To kick off 2023, we're going to talk about freelancing, and more specifically about the different ways of working in the freelancing world. As you'll have gathered from the title, the two most common working methods are agency and fixed-price... but késako? 😛 Contract work Let's start with this, because it's very widespread, especially when the client is a large group. In fact, freelancing is very similar to salaried employment. F...

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...

How important are updates?

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...
