Dans l’épisode précédent "La sécurisation des mots de passe, c’est salée", j’avais expliqué l’intérêt du sel pour protéger les mots de passe de ses utilisateurs. On va voir désormais que cela n’est toujours pas suffisant, et que seul les poissons volants (blowfish) pourront nous sauver la mise !
Saler et hacher ne suffit pas
A la lecture de deux très bons articles sur le sujet : How to safely store a password (en), Exemple de stockage de mot de passe en Java : hashage et salage, est-ce suffisant ? ; on se rend compte que saler et hacher ne suffit pas !

Modular programming is used to break large applications into smaller blocks of manageable code. Module based coding eases the effort for maintenance and increases reusability. However, managing dependencies between modules is a major concern developers face throughout the application development process. RequireJS is one of the most popular frameworks around for managing dependencies between modules. This tutorial examines the need for modularized code, and shows how RequireJS can help.
Eden is a PHP library designed for rapid prototyping, with less code. Yes, Really.
Ever thought about doing a Facebook+Twitter+Google mashup? How about integrating that with PayPal? Is setting up shipping options in your cart a pain? Adding different libraries form different sources add more complexity to your project and ends up to be hard to maintain. Eden simply a set of reusable components, that works with any PHP framework and CMS. Eden makes code logical and readable with dead simple syntax.

QRCode.js is javascript library for making QRCode. QRCode.js supports Cross-browser with HTML5 Canvas and table tag in DOM. QRCode.js has no dependencies.
True story: I was tasked by the lovely Mrs Lawson to buy some curtains that match our carpet during the January sales. I dutifully did so — and had to return to the shop straight away because they didn’t match at all. Mrs Lawson accompanied me, and with a withering glance at her incompetent mate, immediately found some correctly hued fabric, and all was well.
But what’s a middle-aged colour-blind bloke to do? I had early in the curtain procurement process decided against cutting a hole in the carpet in order that I may take a sample with me. (All other mistakes aside, this was a correct decision.)
So, in order to ensure that I would never again repeat the mistake, I set out to make an app that would allow me to capture the colour of an image straight from my camera. Of course, it had to be a web app rather than a native app, because we’re web angels, not proprietary devils.

In this two part series, we’re going to look at Web Storage, one of the best and most interesting features to come out of the HTML5 spec. We’ll look at the history of both Web Storage and cookies, and consider the following points
QCon is a practitioner-driven conference designed for team leads, architects and project management. The program includes two tutorial days led by over 80 industry experts and authors and three conference days with 18 tracks and over 80 speakers covering a wide variety of relevant and exciting topics in software development today. There is no other event in the US with similar opportunities for learning, networking, and tracking innovation occurring in the enterprise software development community.
The intention was that within organizations web developers would work to keep an updated list of html5 features that they would adopt or not. However, Paul Irish and I thought it would be useful if there were a global set of recommendations that web developers could consult and tap on when they are deciding on how to use features. This was the seed for the creation of HTML5 Please.
Starting from scratch, we’re going to learn through these 2 tutorials how to build a small RSS reader with HTML5, CSS3 and WinJS, the Microsoft JavaScript framework for Windows 8. We will then build a WinRT application targeting the Windows Store. We’ll try also to follow the Windows 8 UI design guidelines by using Expression Blend 5. If everything goes fine, you should be able to follow these 2 articles in 30 minutes.
A lot is said about LESS and Sass, and for good reason. CSS is hell to get right and even harder to maintain. LESS and Sass (and similar tools) make CSS into a much more useful language.
But when people talk about why they are so great, they miss the main point. It is true that your style files are now shorter and more readable. However, there is something deeper going on than mere saving of keystrokes and being able to name things.
In this essay, I will try to put into words (and some pictures) what my intuition tells me as a developer and programming language enthusiast to clarify why CSS is innately unmaintainable, does not satisfy its own design goals, and why LESS and Sass make a bad language more bearable. I also will propose solutions which would raise the bar past the high level where LESS and Sass have taken it.

When I started writing for PHPMaster, my first article was about Zend Framework. Since then, the framework has released version 2 stable. Apart from the name, version 2 is really a new project compared to the older version; ZF has been totally rewritten. In this article I’ll give you an overview of the new features and the changes that have been introduced.
Flexbox is a new layout mode in CSS3 that is designed for the more sophisticated needs of the modern web. This article will describe the newly-stablized Flexbox syntax in technical detail. Browser support is going to grow quickly, so you’ll be ahead of the game when support is wide enough for Flexbox to be practical. Read on if you want to know what it does and how it works!
The Android SDK includes a virtual mobile device emulator that runs on your computer. The emulator lets you prototype, develop and test Android applications without using a physical device.
The Android emulator mimics all of the hardware and software features of a typical mobile device, except that it cannot place actual phone calls. It provides a variety of navigation and control keys, which you can "press" using your mouse or keyboard to generate events for your application. It also provides a screen in which your application is displayed, together with any other active Android applications.

An average page is now over 1200kB in size and 60% of that is in images. With all the focus on performance and speed across the web performance industry, you would think that innovating on better image formats would be a top agenda item. Not so. Instead, we are living in a self-imposed world of scarcity of formats, effectively limiting ourselves to gif’s, png’s and jpeg’s.
In practice, deploying new image formats has been painful - just think back to the saga of png. But one would also hope that png was not the last. In fact, if we really want to make an impact on web performance, then image formats is the place to do it. There is absolutely no reason why we shouldn't have dozens of specialized formats, each tailored for a specific case and type of image. But before we get there, we need to iron out some kinks...

jQuery 1.9 removes or modifies several APIs that behaved inconsistently or inefficiently in the past. The majority of these changes have been foreshadowed by their deprecation in previous versions of jQuery, particularly 1.7 and 1.8.
In making these changes, the team's goal was to fix behavior that makes jQuery inconsistent or hard to use, and in the process improve both file size and overall performance.
This list is deceptively foreboding. Most of these changes address special situations and edge cases, and a few are changes that have been widely requested where jQuery's historical behavior has been problematic. As a first step, the best way to see if your code works is to try it with both jQuery 1.9 and the Migrate Plugin as described below.
For now, this guide serves as an appendix to the standard jQuery API documentation, and those pages may not describe the behavior of version 1.9. Please be patient while we update the documentation for the individual pages at api.jquery.com to reflect the changes in 1.9.

The first PHP 5.5 alpha has been publicly released. After having some time to test and experiment with it, we can now bring you our in-depth overview of what to look forward for!
LivePipe UI is a suite of high quality widgets and controls for web 2.0 applications built using the Prototype JavaScript Framework. Each control is well tested, highly extensible, fully documented and degrades gracefully for non JavaScript enabled browsers where possible. MIT licensed and actively maintained.
When you want to build something for the web, it's surprisingly difficult to find out how you can implement your vision across all browsers and operating systems. You often need to search across various websites and blogs to learn how certain technologies can be used. It's kind of like a scavenger hunt, except it's not any fun.
This scavenger hunt is soon coming to an end. Google along with the W3C and several leading internet and technology companies just announced the alpha release of Web Platform Docs. Web Platform Docs is a community-driven site that aims to become the comprehensive and authoritative source for web developer documentation.

Most of us know that with the introduction of what we customarily call “CSS3″1, there have been changes and additions to CSS, compared to what we had in CSS2.1.
Putting all cross-browser issues aside, I thought it would be nice to be able to document all these changes into a single post and keep it up to date.
So if you want a list of everything that’s been introduced into the CSS spec since CSS2.1, here it is.
