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...

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...

Hello over here 🙂, Thank you for clicking on this article, I hope as always you enjoy it 😁. This week, we're going to talk about a hot topic, well hot ... when I see the heated debates on LinkedIn that I never take part in, because I find it a debate that is a bit pointless. And yes, I'm talking about telecommuting, I don't really understand all the fuss about this practice, but hey, why not, today I'm going to give a bit of my vision of the thing and above all: ho...

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...

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...

Remember the 1990s? Remember what? Some of you weren't born then? Ah OK .... all right! Back in the 90s, a "trendy new thing" was just starting to make waves, and for the most part, apart from a small group of geeks, nobody could see what it could be used for... that trendy little thing was... the Internet. Thirty years on, I think we've understood what it could be used for.... For me, blockchain is a bit like the Internet at the time, nobody really knows what it could be used for, and in 30...

Good morning Good morning, This week, for once, we're going to talk about software development (no kidding??). And I'm going to try to shed some light on why I chose web development over other fields, and ... there are some! (who's for a bit of assembling here??) Got a hot drink handy? OK! Let's get started! Other types of developers This list isn't exhaustive - there are bound to be areas I haven't mentioned - but I'll try to give you an idea of what's out there. Foreword: Wh...

Hello? How are you? Once again this week, we're going to talk about blockchain, but this time from a more dev point of view than the other times. Did you know that it's possible to develop on blockchain? Let's talk about it. Is a decentralized application (dApp) completely decentralized? As I write these lines, there are points of centralization in these applications, in fact it's relatively simple to understand "why? "These dApps run in a browser, but a browser only recognizes a fe...

Hello ?, This week, we're going to talk about business servers... (more of a web server, actually). Did you know that since January 2023, 10-year security updates are no longer reserved for RedHat and Microsoft Widows Server? And yes... there's a newcomer, so shall we talk about it? Enterprise and servers As technology enthusiasts/developers, we want to play with the latest toys, download the latest Debian for testing, or install a web server on a Raspberry Pi. But once we ge...

Hi there, how are you? 😁. Thanks for clicking on this article, I hope you like it even if the subject is quite specific 😛. This week we're going to talk about APIs, developers use them every day in their work, bah yes, for example for online payments often we use Stripe's or PayPal's. But we're going to go a little deeper, because there are two types of API: public and private. Are you ready? Here we go 🙂. Why this article? When I'm not working on custo...
