Hello and thank you for clicking on this article! Some time ago I told you about my nuclear disaster, the super adventure of a server that suddenly shuts down and gives no sign of life. Recently I received an email from my service provider saying "Please note that your Ubuntu version will soon no longer be supported. You should upgrade to 22.04 minimum". Well, even if this email seems nicer, I still had a feeling of déjà vu of my server getting lost in the cosmic uni...

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...

Hello and thank you for clicking on this article 😁 Today we're going to talk about experimental code that I've been interested in recently. To contextualize, I finished a PHP course for a promo I had as a trainer. Once we'd seen the basics and got to the end of the program, we naturally moved on to the MVC and object-oriented aspects of implementing a project in native PHP. It was at this point that I asked myself the question of how to implement a router in a project of this t...

Hello everyone and thank you for clicking on this article 😊 I don't know about you, but there's a little shopping site called Amazon that I find really handy. Today I wanted to tell you about something you can implement on Sylius that can make all the difference to your e-commerce. "Wait a minute, you mean that Amazon is developed with Sylius? No, Amazon is much older and existed before the very idea of Sylius. 😛 On the other hand, these days, for an e-commerce stor...

Well, happy new year! Admittedly, I'm a little late in wishing you a happy new year, but January is always the month for getting back into the swing of things, planning for the year and getting back in touch with just about everyone. Not to mention the galettes ... anyway 😛 Today I wanted to talk about a handy little tool that appeared on iOS 14: widgets. Personally, I use them a lot for apps that give me info at a glance like the weather, the day's to-do list, the calendar, et...

Hi there 😁, Thank you for clicking on this article, I hope you enjoy it, despite its very "niche" nature....

Without realizing it, you use them every day. For example, on your packages ordered online, there are labels. These self-adhesive labels are created using a label printer. The one I'm most familia...

Hello little wolves 🙂, Happy New Year 2025! So, have you been spoiled for Christmas? 😁 As far as I'm concerned, in December I wanted to set myself a slightly "silly" challenge. The idea was to create three free SaaS that meet real needs that can arise in VSEs and SMEs. In fact, you've probably already seen them... Yes, the little orange insert above the blog posts! So, shall we talk a little more about these little SaaS and their history? Let's get started! Creati...
