Note Some code on the website may differ slightly from the listings presented in the printed book. Initially we tried to use this site to keep pace with the API changes, and for about a year we didn’t do too badly. In the end though, with the release of API v3 it was hopeless. Most of this code still works very very well, however with API v3 most of it can be done a lot faster, leaner and more maintainably than the code presented here.
To whet your appetite, you can also read a PDF of Chapter 4 in full.
