Spoofing User-Agent with Chrome’s WebRequest API
Whenever you ask for a page on the web, your request has a lot of data attached to it. One part of your request (the “user-agent” string) describes your software environment—usually your operating system and your browser’s name and version number. Like many things on the web, this data is a convention, not a law. […]

JavaScript: Firefox Nightly introduces DOM Joystick Events
Late last week, excitement buzzed here at Bocoup, when David Humphrey of Mozilla dropped us a line with links to a Firefox nightly build that had added rudimentary support for a set of DOM Joystick events. Several hours later we, along with Jason Orendorff and TedMielczarek of Mozilla, put together a couple of prototype experiments […]

Synchronizing HTML5 Slides with Node.js
I gave a talk in February on Advanced jQuery Templates that had an interesting and unique twist. Instead of changing slides using traditional presentation delivery methods such as a clicker or a laptop keyboard, I used my smartphone which made asynchronous calls to a Node.js server. The server then propagated events to all connected viewers, regardless of […]

The Strategy Pattern in JavaScript
I was recently re-factoring some code under Rick‘s guidance, and we implemented what I would later recognize as the Strategy pattern. JavaScript’s objects and first-class functions make this pattern extremely simple to implement, although you can optionally take some additional steps to add robustness. Background: Design Patterns A lot of my troubles with design patterns […]

Implementing the Google Contacts AuthSub flow with jQuery
Google AuthSub follows a common oAuth style handshake flow. Unfortunately, it is not immediately clear how to implement this flow with the AuthSub GData JavaScript Library using their documentation examples or the library’s API. I recently implemented the flow for a Google Contacts viewer that we are working on here at Bocoup, and thought I […]

JavaScript: EventSource is Long Polling
UPDATE: With some serious modification to the server end point, Luke Morton was able to achieve a single open event that fires message events as responses are received via a “push” from the server: https://gist.github.com/1002722. By modifying the original example’s PHP end point, Luke’s approach was to omit the closing PHP tag (ensures that no […]

JavaScript: Firefox/Aurora 6 and EventSource API
I originally wrote this as a comment on Mozilla’s “Aurora 6 Is Here” article – but I’m impatient and couldn’t wait for the comment to be moderated. Also, I haven’t posted in a while and figured Bob the Rooster would appreciate it. Glad to see support for the EventSource API has made it to Firefox. […]
