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...

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 there! Today's article is going to be quite short, but practical. In my little life as a freelance developer, I have to monitor my customers' applications and websites to make sure they're up and running, including the site you're currently on.... So I don't miss a single incident, the device that alerts me if there's the slightest problem with one of the services I manage is on my wrist... and yes, it's the Apple Watch. Basically, I'm someone who doesn't like notifications; they t...

What is a slash? Let's start by explaining what a slash is. A slash is simply the slash found in Internet addresses, which is simply "/". It's also found in file paths on Unix-based operating systems (such as macOS) or Linux (such as Ubuntu). On Windows, the convention is for file paths to use backslashes, i.e. the same slash, but the other way round. A little history. In the past, putting a slash in Internet addresses made it possible to differentiate a "file" from a "folder".I use qu...

Hello everyone, This week we're going to talk about the link between creating content, like the one you're reading right now for example, and increasing sales for your business... because yes, there is a link, and yes, it's possible. Why can content creation increase sales? The first question to ask yourself is "What do you sell?". For most of you, the answer would be "I sell development time" or "I sell training courses"... and so on. But really? No... "What? What do you mean? I'm...

Today, I've chosen a subject that is sometimes neglected by developers, but is nonetheless very practical: testing. No, I'm not talking about testing your code before sending it to production by pressing F5 to see if everything works. 😛 I'm talking about automated tests that you write following the logic of an algorithm to create practical cases that can be launched at different times. Imagine you have an e-commerce site and you want to test that a product is actually added to...
