The Challenges of Developing an Ajax Application
I do not think anyone prefers the old style click->reload style applications over newer Web 2.0 applications. Think back to the first time you saw Google Maps: was your first though closer to “Cool!” or “Mapquest’s UI is so much better?” There was an initial wave of resistance to developing applications with this technology, with […]

Version 3.0, Revisited
Months ago, I began to rethink the visual identity of this site. Moving from Blogger to Wordpress made the material far more searchable and browsable.

Audio Passthru on PowerMac
For many months, I’ve had my iPod sitting on the desk in its dock, with the speakers plugged into it. The old PowerMac sits on the floor, outputting its alerts through the built in speaker. It’s not an ideal setup, but it works, especially considering the music is more important than dings.
