Yes, I'm back this week... Did you miss me? No, well ... ? Another thorny subject this week, I'm often asked: "Hey, do you know a free web host? How do you make a site for free? ... etc." So here I'm going to explain why what we think is free isn't, and more importantly, why we think it is. Everything on the Internet is free - where does that come from? The Internet is a medium, and like many media before it, its business model is based on advertising, often aimed at individuals (there'...

The what? What's this now? No, I'm sure you've already heard of it. Double authentication, often referred to under the acronym 2FA (for 2 Factors Authentication), is the principle of requiring 2 proofs of identity from a user to connect to a site, app or service. So here's a scoop: you've all used this before, and for a very long time. And yes, when you withdraw money from a cash dispenser (or make a contact payment with your bank card), it's 2FA. You use your card itself, with its number a...

Hey, hello there ... it's been a long time ... well, a week! How have you been? Sunbathing, sunbathing? Yes, it's important to have a good time! Speaking of good times, have you been sitting on a terrace recently? No, because that's what we're going to talk about today. In fact, we're going to be talking about MealPay, a project that grew out of an adventure that began with my partner Josselin Dionisi. The QR Code as a contactless payment system In fact, the basic idea is simple: we're s...

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...

New week, new article! How are you? The wife? The kids? The goldfish? (is the goldfish important?) This week we're going to try and figure out what the padlock in your browser's address bar means, so yes on this site there is one (there, I've just saved you the trouble of looking up to check). Naaaaaa but don't go away, it's an interesting subject! promise?. Before you start I'm redirecting you to the "asymmetric encryption" paragraph of my article on ransomware, because there's no p...

Remember the 1990s? Remember what? Some of you weren't born then? Ah OK .... all right! Back in the 90s, a "trendy new thing" was just starting to make waves, and for the most part, apart from a small group of geeks, nobody could see what it could be used for... that trendy little thing was... the Internet. Thirty years on, I think we've understood what it could be used for.... For me, blockchain is a bit like the Internet at the time, nobody really knows what it could be used for, and in 30...

Come on, this week I'm making enemies! Here we go! Since the beginning of the crisis, we've been seeing "Get a website and increase your visibility" all over the place. Watch out! Hold on to your hats, a huge "scoop" is coming: a site costing just a few euros a month won't bring you ... ANYTHING. What's that? What do you mean you knew? Ah yes, nothing worthwhile in life is easy to achieve... that's true. What's a website for? Let's say you had your "ma-super-boutique.com" website made,...

Ahhhh, passwords ... I've already talked about them in a previous article, but in this one we're going to talk about a method for saving our dear little users from having to remember their passwords... Apple now makes it possible to "sign in with Apple", basically the same thing as Google, Facebbok and all the others. But! the Apple way... In this article, we'll look at how to integrate this feature into a Symfony application. You need Apple developer access to access "sign in with Apple...

New week, new article, how are you? Well, the title isn't crazy, we agree, but SEO and all that ... You're present on social networks, you have subscribers, relations ... etc. (in short, there are people in your network!), but when you publish something, your publication reaches few people ... so you ask yourself "But WHY? "I'd say, "That's just the way it is, life's unfair", but that'd be pointless and would evade the question.... Social networks are private companies I think it's wort...

Like any dev, I sometimes want to test small pieces of code, make an example landing page to test a service or API... In short, there are many cases where you just want to try something out, without it being a full-fledged project. To do this, of course, we run our development environment on our own machine, "locally". Let the world benefit from our local project Okay, that's all well and good, but what if we need to access this local code from the outside? And yes, it can happen...
