New Book: From Java to Ruby by Bruce Tate

Given the recent debate sparked by Joel Spolsky's questioning of Ruby's fitness for enterprise production use, and also a some recent comments on this site about "sneaking" Ruby into an environment, it seems worthwhile to mention a new book published by Pragmatic Bookshelf called From Java To Ruby: Things Every Manager Should Know (Amazon), by Bruce Tate, a long time Java supporter and author who has more recently been covering Ruby. It's clear from the promotional text where the book stands:

As a development team, you want to be productive. You want to write flexible, maintainable web applications. You want to use Ruby and Rails. But can you justify the move away from established platforms such as J2EE? Bruce Tate's From Java to Ruby has the answers, and it expresses them in a language that'll help persuade managers and executives who've seen it all. See when and where the switch makes sense, and see how to make it. ...

Most books talk about the benefits of technology, but risk, skills, and fit also come into play. Other books cannot overcome the most basic management objection: risk. This book attacks user objections head on, in language friendly to developers and managers.

The description for the book on Amazon says that the book uses a decision tree process to work through the issues, which I found interesting. A glance at the Table of Contents (PDF) also reveals that after a series of chapters that appear to argue pretty squarely in favor of a move from Java to Ruby are followed by some suggested strategies.

Comments welcome--has anyone read this one?

Update: Incidentally, InfoQ.com has published this article by Bruce Tate related to the Java To Ruby book.

Thanks for reading,
