I have been told that the long-awaited book Real World Ajax is nearing completion.
This book includes two chapters by myself and my good friend Jay Fienberg on Ajax Security and the creation of an Ajax IM client.
The book will be like the OED of Ajax, I think it's like 2 million pages long or something. So it's a steal at the pre-order price of $50.
Check it out. It's almost ready for press!
