Take Screenshots of Webpages with HTML2Canvas

html2canvas allows you to take “screenshots” of webpages or parts of it, directly on the users browser. The script renders the current page as a canvas image, by reading the DOM and the different styles applied to the elements.

It does not require any rendering from the server, as the whole image is created on the clients browser. However, for browsers without canvas support alternatives such as flashcanvas or ExplorerCanvas are necessary to create the image.

The script should work fine on the following browsers: Firefox 3.5+, Google Chrome, Newer versions of Opera, >=IE9 (Older versions compatible with the use of flashcanvas).

Standalone Test Spies, Stubs and Mocks for JavaScript

Sinon.JS is a Standalone test spies, stubs and mocks for JavaScript. No dependencies, works with any unit testing framework. A test spy is a function that records arguments, return value, the value of this and exception thrown (if any) for all its calls.

Test spies are useful to test both callbacks and how certain functions/methods are used throughout the system under test. Use a stub when you want to control a method’s behavior from a test to force the code down a specific path. Mocks are fake methods (like spies) with pre-programmed behavior (like stubs) as well as pre-programmed expectations.

Suhosin – Advanced Protection System for PHP

Suhosin is an advanced protection system for PHP installations. It was designed to protect servers and users from known and unknown flaws in PHP applications and the PHP core. Suhosin comes in two independent parts, that can be used separately or in combination. The first part is a small patch against the PHP core, that implements a few low-level protections against bufferoverflows or format string vulnerabilities and the second part is a powerful PHP extension that implements all the other protections.

If you are using PHP only for your own server and only for your own scripts and applications, then you can judge for yourself, if you trust your code enough. In that case you most probably don’t need the Suhosin extension. Because most of it’s features are meant to protect servers against vulnerable programming techniques. However PHP is a very complex programming language with a lot of pitfalls that are often overseen during the development of applications. Even PHP core programmers are writing insecure code from time to time, because they did not know about a PHP pitfall. Therefore it is always a good idea to have Suhosin as your safety net.

Create Games with melonJS HTML5 Game Engine

How to Build a Custom HTML5 Video Player with jQuery

As professional web designers, we want to create a video player that looks consistent across browsers. Each browser however provides its own different look and feel for the player, from the minimal approach of Firefox and Chrome, to the more shiny controls of Opera and Safari. If we want our controls to look the same across all browsers, and integrate with our own design, we’ll have to create our own controls from scratch. This is not as hard as it seems.

All media elements in HTML5 support the media elements API, which we can access using JavaScript and use to easily wire up functions such as play, pause, etc. to any buttons we create. Because the native video player plays nicely with other open web technologies, we can create our controls using HTML, CSS, SVG or whatever else we like.

Article: Building a custom HTML5 video player with CSS3 and jQuery taught us how to build an easily customizable HTML5
