Following the fire in a datacenter in France, I saw reactions on social networks such as "I've got my company in your servers", which gave me the idea of writing this article.Of course, it's not the owner of the data center who's to blame here, but accidents like this do happen, so you need to be prepared. By having a data backup strategy. Can you imagine? Losing your accounting data? I've already touched on this subject in my article "How to protect yourself from ransomware". The disaster r...

I thought it would be interesting to write an article on the subject now that I've set up a Messenger bot for my Boréales Créations Facebook page. What is a Messenger bot? You've created a robot? It's your fault, isn't it Skynet? Well, not yet anyway. Here the Messenger bot is simply used to answer for you when people, prospects, customers write to you on your Facebook page. 😃 You know what it's like when you're busy, you don't necessarily check all the notificat...

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...

Following my first article, I was now able to run a development environment to create Symfony projects. Okay, that was all well and good, but for the moment it was only running locally on my MacBook, and that's no way to host a site. Since shared servers are already a hell of a thing to configure for a simple site, I didn't dare imagine running Docker on them. So I opted for a dedicated server from Scaleway and once I'd placed the order, I installed Docker on Ubuntu 20.04. I organize...

It's a widespread practice, and understandably so: dozens or even hundreds of different passwords to remember, it's complicated. Nevertheless, you should be aware that it's a very bad practice that can one day turn against you, and as I say, prevention is better than cure. How are passwords entered on sites and applications? Before we understand why it's a bad idea to use the same password everywhere, we need to understand how and/or where your passwords are stored. What happens whe...

E-commerce is an ever-growing sector, with consumers becoming accustomed to this mode of consumption that allows them to find everything they want without leaving their living rooms.In this article, I won't talk about the so-called "sales tunnels" - I'll save that for a future article. Here, we'll talk about the e-commerce store itself. Site ergonomics To begin with, the days when people mainly consulted the Internet on their computers are over. In fact, on average, between 70% and 80% of...

Sharing resources is at the heart of the Internet, and social networking buttons can be found on all kinds of sites, making it easy to share content so that others can enjoy it.

This article will be very brief, showing how to use this API. window.navigator.share This is the name of the function for sharing via the native window of the operating system, iOS or Andro...

What is a slash? Let's start by explaining what a slash is. A slash is simply the slash found in Internet addresses, which is simply "/". It's also found in file paths on Unix-based operating systems (such as macOS) or Linux (such as Ubuntu). On Windows, the convention is for file paths to use backslashes, i.e. the same slash, but the other way round. A little history. In the past, putting a slash in Internet addresses made it possible to differentiate a "file" from a "folder".I use qu...

Ah Docker! I've been hearing about it for years, but like many people (I think) I hadn't yet taken the plunge. I'd read several articles on this technology, and even looked at the official documentation to try and tweak a few things, but it was still too vague for me. First of all, what is Docker? It's (almost) magic in the sense that you don't need to worry about your server configuration, your OS or your version of PHP, Node, React ... in short. You just code on your machine, and miracu...
