For those wondering about the status of his book, "Zend Framework: Survive The Deep End", Padraic Brady has posted an update of where he's at.

Since the rumor mill has been active a while, I confirm two chapters of the book will be released this week. [...] To kick off a new spell of book updates, the next Chapter will be "A Simple Hello World Example", with an Appendix titled "Virtual Hosts On Apache 2". The following Chapter approximately one week later will be an introduction to the application to be built for most of the first half of the book.

He notes that, while normal print books usually have schedules, self-publishing is a bit more flexible. He does want to assure the readers of the book that work is actively being done and the chapters will keep coming.
