Hello, hello, How are things around here? Not too cold? This week, we're diving back into the world of Symfony with a short article on bundles. We're going to take a look at the bundles you need to know when you're a Symfony developer. The idea here is to bring together the bundles I see and use most often in my projects. Here, we won't really be talking about bundles that are part of the Symfony "core", such as the "DoctrineMigrationbundle", which you'll find everywhere. Are you read...

Hello ?. Well, yes, we're back together this week for an article that's more "entrepreneurial" than "tech", but don't worry, tech isn't far off. If you're an entrepreneur, you might learn a few things, and if you're not, well ... you might too! Foreword: In this article I'm going to talk about products and services, there's no commercial connection with the products I'm talking about, I'm only doing it because I find it interesting and because it may solve problems for some of you.

Hello there, This week we're going to be talking about image formats. In fact, this article follows on from my article on CSS, and we're going to be talking about optimizing sits, in this case images. First of all, we'll review the older image formats, find out how to optimize them and finally talk about WEBP. We'll even see how it's possible to have a site or application that uses this format automatically, as is the case on the site you're currently visiting. Other image formats We'...

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...
