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 […]

Bocoup is excited to be working with Gradient Studios to port the hit mobile game Fieldrunners, by Subatomic Studios, to HTML5. This is the second in a series of weekly development blog posts. Last time, I posted about some basic WebGL particle system benchmarks we ran. We were extremely pleased with the results. The next […]

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 […]

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 […]

I’ve recently been working on an update to JavaScript Debug, which has me doing a lot of cross-browser testing, and I noticed a few “interesting quirks” with try…catch in Internet Explorer 6-8 that I couldn’t find documented anywhere. The Backstory Since the primary goal of JavaScript Debug is to normalize the console cross-browser, I’ve been […]

The “Wayback Machine” is one of the more important services in the history of the Internet (and happens to be named after a great gag on the old Rocky & Bullwinkle show). From about 2001 through 2005 it could be counted on it to give you a reasonable snapshot of many of the home pages […]

UPDATE!!! This morning (2010-10-22) Chromium dev channel updated to Chromium 8.0.552.11 dev and the indexedDB implementation has been renamed to webkitIndexedDB. I must admit – sometimes browser updates are like Christmas. Like today. I updated Chrome and as usual I went through the motions of inspecting the window (DOMWindow) object in the console looking for […]

Last friday Google publicly announced a new way to view traffic on your web site; by using the web site itself. This is a replacement for the clumsy Site Overlay feature that has existed since the Urchin analytics system was absorbed by the software giant. It looks like a great way to visualize the traffic […]

The Official Opera Blog has announced that Opera 10.70 will feature a reimplementation of the EventSource API. I say “reimplementation” because Opera was actually the first modern browser to add support for Server Sent Events back in 2006. The implementation was awkward and required a DOM element. Last week, Opera Core Concerns posted an update […]

I feel like I've given jQuery UI a bad rap. I passed judgement too fast. At first glance, it was a pile of rigid prefab user interface objects generated by jQuery being peddled as 'official'. I know now that it's much more. jQuery UI is not (just) about a fancy accordion slider. It's a framework […]
