I’ve been researching vCard for a project involving contacts management. This is a quick overview on vCard aimed at developers, with a demo and stealing the example from wikipedia’s vCard entry. The official standard is here.
The Format
vCard is a standard for representing contact information, the kind of info you would see for a contact in [...]
This is the third in the four-part series on Ajax functionality and usability patterns (Book: Part 4, pp 327-530). An audio discussion of visual effects is ideally short and sweet, so this podcast is but 13 minutes long.
This 13-minute podcast covers ten patterns of Ajax Architecture (Book: Chapter 16, pp 445-472):

The third podcast in this series of Ajax Programming Patterns. The 29-minute podcast covers five patterns. As with the previous podcast, there is reason for concern about the audio quality herein.

Continuing from the previous podcast (*cough* 12 weeks ago), more programming patterns. Unfortunately, this recording (and the next one) went pear-shaped. Sorry. I do, however, recommend them to those of you who’ve been wondering what an Ajax talk would have sounded like in crackly 1930s recording technology, and one in which the speaker has a [...]

As just mentioned, I’ve posted code for the AjaxPatterns demos and the tutorial. You can run the tutorial here. The interesting thing here is it’s all designed to be hand-coded, so you can see how an Ajax app can easily be built up from first principles, good for learning. The final demo then uses an [...]
