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). […]

Javascript Web Workers: From Basics to jQuery.Hive
This is long overdue. Also, it should serve as a context for my slides from jQuery Conference, San Francisco 2010 (use the up and down arrow keys to navigate). Whether or not you’ve read the WHATWG Web Worker spec and are looking for more information about Javascript multi threading OR you already have a rudimentary […]

Web Audio – All Aboard!
In this post I will talk about Mozilla’s Web Audio Data API. I will cover where we have come from, demonstrate some of the incredible results that have already been achieved; I will talk about why audio in the browser is so important, take a look at where we are headed and explore some of […]

CSS SVG-Filters Elem.style & xlink:href=”url(#id)” #fail
I have been playing around with SVG Filters a lot over the last few weeks and I have to say that the SVG Filters are a) really freekin’ cool and b) powerful in ways yet undiscovered. When these things land cross-browser, it will really polish off the modern web-app paradigm, adding a level of depth […]

Publish/Subscribe with jQuery Custom Events
The Publish Subscribe or pub/sub pattern is used to logically decouple object(s) that generate an event, and object(s) that act on it. It is a useful pattern for object oriented development in general and especially useful when developing asynchronous Javascript applications. This post explores its implementation in jQuery. The Dojo javascript framework provides an explicit […]

JavaScript Enumerable.Map() with WebWorkers
For those with short attention spans, here’s how you call the function: map(enumerable, mapFunction, callback, numWorkers); I wanted an easy way to divide up a parallelizable task with Web Workers, so I create a Worker enabled Map function for arrays and objects. It works just like the map function in your favorite functional languages, except […]

Quickest Loop Through an Object
A little experiment to find the fastest for-loop for an object. Approx. Results: ARY-INDEX: “for(var i = 0” -> 13ms OBJ-INDEX: “for(var i = 0” -> 218ms OBJ-KEY: “for(var i in” -> 975ms var len = 1000000; // ARRAY VERSION var check = 0; var ary = []; for( var i = 0, l = […]

Faster Javascript – Part 2
In Faster Javascript Part 1 we compared a three methods for evaluating a string of alien DNA. With Switch, Boolean & Conditional going head to head, Switch was the clear winner with Conditional (Ternary) trailing way behind. Testing methods is one thing, but there’s more to writing fast code than just testing. For example: order […]

Long Division In Javascript
We are exploring the possibility of developing a workshop to help high-school students solidify their knowledge of core mathematical concepts using a computer to write Javascript code. The best way for a student to demonstrate and reinforce knowledge of mathematical concepts is to be able to teach them or explain them to another person. We […]

Compiling Clarkson’s Hull in OS X
If you’re interested in parametric or generative design (the terminology doesn’t seem to be well standardized) you have probably run into Voronoi diagrams and their cousins, Delaunay triangulations. The latter can be used to make concave hulls given an input point set, a construction which is called an Alpha Shape. Jim Clarkson wrote a great […]
