To avoid contacts, restaurants are now using QR Codes to allow their customers to consult the menu. The PDF format To start with, you'll need the menu in PDF format. The "PDF" format is a standard format that can be read on any device, iOS or Android, so using the PDF format means you won't have any compatibility problems with your customers' phones. It's also possible to have a simple web page, but since that's more difficult to achieve, stick to a PDF format, which you should already ha...

I bootstrap, you bootstrap, he bootstrap, we bootstrap... Oulah, what's wrong with me ... ? Hello, hello? This week, we're going to talk about CSS, and more specifically about CSS frameworks, the best-known of which is Bootstrap, and the new kid on the block, Tailwind, who's trying to steal its number 1 spot... Bootstrap released in 2011 This framework arrived at a time when the web looked nothing like it does today - just to give you another date, Chrome came out 3 years before. B...

Oh no, did he say hacker, like too dark, behind black screens and all? Actually, no, in people's minds, a "hacker" is malicious and does some pretty uncool stuff, but actually, no. Hackers are already divided into "white hats" and "black hats", the former being harmless, while the latter are not so nice. This week, we're going to talk about the "hacker spirit". Of course, that's my own definition, and others will have other visions? My definition of the hacker spirit A hack is a "d...

Hello ?, This week's article is based on something that happened to me recently. During an Ubuntu server update, it seems that the bind9 package, after the update, started to crash after a while. The problem is that on this machine, I need DNS resolution, as it hosts services that need to complicate with other online services like Stripe. So I end up with a call informing me that when it comes to entering the bank card on this Symfony application, well, it doesn't display the form reques...

Hello ?, After Josselin's article on languages and Sylius, I'd like to take you through the framework in its entirety... Have you ever come across a complicated e-commerce project? Or rather, have you ever found yourself unable to adapt or customize your e-commerce site the way you want? As if you had to adapt to the solution rather than the solution adapting to you? Does this sound familiar? If so, I've got something for you: Sylius. Have you ever heard of it? No ? In any cas...

Hello, hello? Have you ever watched a child playing with "Legos"? Stacked one on top of the other, they create complex structures that are both unique and fundamentally similar, because they all share the same basic elements... What if I told you that playing with Legos is a bit like our topic for today... Welcome to the concept of object-oriented programming (OOP)! It may sound like an obscure concept, a maze of jargon designed to confuse, but fear not, it will! We're about to emba...

This text was on the home page of the site, but after updating it I decided to move it to the blog? 1998 - Discovering computers At elementary school, I discovered computers. At the time, Windows 95 was the star product, and I fell in love with these machines. A teacher, noticing this growing passion, decided to encourage it by giving me a computer; it was a Compaq, with a 486 processor and 4 MB RAM. At the same time, I got an Amstrad CPC equipped with BASIC, which marked the beginning of...

Hello everyone and thank you for clicking on this article. 🙂 There's a debate that's been raging for a long time in the developer community, namely: PHP vs Javascript. Leaving aside the relevance of such debates (each techno having its pros and cons), today I've decided to perform the complete heresy. 😛 Let's take a look at how to integrate React (a Javascript Front library) into a Symfony project (PHP back-end framework). 😀 "Isn't that a bit counter-intuitiv...

This week's article is all about developers, yes ... there's something for everyone. How are you? Whit Monday and all that ... yeah well, that's no reason to get up and get to work. What's a slug? For the guys at the back, we'll remind you what a slug is. It's a "string" normalized so that it can be inserted into a URL, for example on the article you're reading in your address bar there's no "index.php?article=49" because well .... it's ugly (if it's ugly, that's all.), a nice URL that l...
