It uses native where available and an invisible flash player to emulate for other browsers. It provides a consistent html player UI to all browsers which can be styled used standard css. audio.js focuses on playing mp3s. It doesn’t currently support the ogg format.

Organizing A jQuery Application - Jupiter JavaScript Consulting
Thursday 11 November, 2010 by moschel Earlier this week, I realized that every organizing-a-jQuery-application blog, article, and conference talk misses the most important lesson on how to organize a jQuery app. They talk about how to organize an individual widget or piece of functionality, but not how you can break up an application into logically separate and testable components. Separation of concerns is the bedrock of software engineering. It is the best way to achieve a quality, error free, and maintainable project. Think about it ...
The manifest is a nice summary of the contents, and allows browsers to cache the app for offline use. Combine this with mobile Safari's "Add to Home Screen" button and you have yourself a free chalkboard app that works offline. CACHE MANIFEST / /zepto.min.js /chalk.js /images/background.jpg /images/chalk.png /images/chalk-sprites.png /images/chalk-tile-erase.jpg /images/chalk-tile-red.png /images/chalk-tile-white.png /stylesheets/chalk.css The rest of the HTML is mainly structural.

evercookie - virtually irrevocable persistent cookies
evercookie is a javascript API available that produces extremely persistent cookies in a browser. Its goal is to identify a client even after they've removed standard cookies, Flash cookies (Local Shared Objects or LSOs), and others. evercookie accomplishes this by storing the cookie data in several types of storage mechanisms that are available on the local browser. Additionally, if evercookie has found the user has removed any of the types of cookies in question, it recreates them using each mechanism available.
Erich Ocean, a SproutCore contributor since the early days, and others have been hard at work on a new fork of the SproutCore project called Blossom , which reimagines the view layer without the use of any HTML or CSS. How does it do this? It renders the entire view structure of your application on a giant HTML5 canvas element.

Sylvester - Vector and Matrix math for JavaScript
var V1 = $V([3,4,5]); var V2 = $V([9,-3,0]); var d = V1.dot(V2); // d is 15 var c = V1.cross(V2); // c is the vector (15,45,-45) var M1 = $M([ [1,7,3], [9,4,0], [2,7,1] ]); var M2 = $M([ [6,2,8], [9,1,3], [0,7,6] ]); var M = M1.x(M2); // M is the matrix // 69 30 47 // 90 22 84 // 75 18 43
SimpleYUI is a new way of loading and instantiating YUI. The SimpleYUI file contains a rollup of basic Ajax library functionality: DOM tasks, event abstraction, transitions, and Ajax. Unlike other ways of loading YUI, SimpleYUI creates a YUI instance immediately upon loading, binding all included components to a global Y . Using SimpleYUI is easy:

Functions that take a variable number of arguments should have the last argument named var_args . You may not refer to var_args in the code; use the arguments array. Optional and variable arguments can also be specified in @param annotations. Although either convention is acceptable to the compiler, using both together is preferred.
