Javascript Typed Arrays: Method Support
Al MacDonald recently posted http://stage1.bocoup.com/blog/javascript-typed-arrays – which is an interesting look at the benchmarkable speed differences between FireFox 4’s Float32Array constructor and the traditional Array constructor. As expected, the Typed Arrays are definitively faster due entirely to native optimization: they only allow integer or floating point numbers (respectively to their Int or Float prefix); additionally […]

New Training: Foundations of Programming with JavaScript
Since I joined Bocoup just a few short weeks ago, I’ve been spending a whole lot of time talking to Jory Burson. She’s the training coordinator here, and she’s everything you’d want in a training coordinator at a place like Bocoup. Most of our conversations have been focused on something we can’t help but notice: […]

Javascript Web Workers: From Basics to jQuery.Hive, Part II (Browser Implementations)
As I mentioned in Part I, the Web Worker API is available for use in Firefox 3.5+, Safari 4+ and Chrome 4+, however the implementations are inconsistant. This has been completely overlooked by every single tutorial I’ve found. The issue revolves around the accepted argument to postMessage() (from both the main window and the worker). […]
