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'...

Hello, hello 🙂, Thank you for clicking on this article, was it the cow photo that made you click? So, yes... I see what you mean...

In the first part, we'll cover the basics, and in the second, we'll take a look at some very concrete cases....

Hello there, This week's article comes from an observation I made recently. Before, in Chrome, when you visited a site that offered OpenSearch, it automatically added it to the browser's search engines, so all you had to do was type "a keyword" + space and start searching directly from the browser's omnibox. This browser behavior has recently changed (perhaps for the better, as it prevents anything and everything from being added to the browser). Now, in Chromium (and therefore Chrome and...

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...

Hello 🙂 Lately we've been talking about Turbo and iOS, and about making PWAs installable. This article is the continuation of those two articles (well, more the one on iOS), so I invite you to skim it, because even if the two systems are quite different, the principle is the same. The application in production As always, the app we're going to talk about is the one I use every time I want to test new technologies.

Hello Hello ?, Windows isn't my main operating system, in fact I'm more Linux / macOS, but that doesn't stop me from following what's going on with Windows and using it from time to time. It has to be said that Microsoft's work over the last few years has been quite remarkable; between the terminal, "WSL 2" and "Powershell", there's plenty to do. This week, I'd like to talk a little about "PowerToys", a set of tools made available by Microsoft to enhance the Windows experience. As the...

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...
