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...

Setting the scene I've been working with Les Frères Marchand, for over a year now, at first we made a website together (it was Ludo Dev CMS's second instance), then we got the urge to create an online cheese shop together, which has been online since September 2021. On this cheese shop, everything is automated to simplify life for customers...

How are you? Last week, the "Ludo Dev E-Shop" explanatory page was released. On this page, it's explained that the emphasis has been placed on the user experience, and that everything has been done to try and keep the experience as simple as possible. Behind this interface, there's a lot of technology (full automation), but is this technology alone enough? In this week's article, we're going to talk about the user experience, and how to make it a pleasant one. For this, I'm going to use t...

Hey there. How are you? Good, not too cold? so much the better! This week's article is for my fellow developers, and we're going to talk about search ... but real search! I often see MYSQL used as a search engine ... It's a fact! In the projects I've worked on, I've often seen this database management system (or MariaDB or Postgresql) used as a search engine, with things like "where my_attribute LIKES '%blabla%". And this is a very bad practice... What's the real use of a relational...

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...

Hi there, how are your vacations going? Today we're talking about a subject that's all too trendy: the health pass (yes, I'm still in vogue!). What do you mean? Another thorny subject? But no, no ... it'll pass. This article is in the same vein as "the HTTPS padlock" and "ransomware", because the health pass uses cryptography, but not for encryption. Ready to go? Let's get started! How do I get a free health pass? Ah! that's why you're here (you little rascal?), OK, I'm going to give y...
