Hi there 😁, Thank you for clicking on this article, I hope you enjoy it, despite its very "niche" nature.... But hey, this adventure happened to me in December 2024, so I figured I'd make an article out of it. Are you ready? Let's get started! What is a label printer (Zebra)? 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.

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.

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...
