Is "Hudson 3 Essentials" for programmers that have other continuous integration experience? Or would something like this be helpful to someone like me, who has never used a continuous integration tool?
I would say you would be the perfect audience for the Hudson 3 Essentials book. The book starts with no assumptions about experience with other CI tools. The book is example driven and covers the main features of Hudson 3. I wanted the book to be very hands-on and show more than tell you how to do things.
If you have experience with CI tools other than Hudson/Jenkins, the book could help you quickly get up to speed on Hudson.
Non-programmers (operations users or managers) may find the book useful as it shows how to use Hudson 3 to track and understand the development life-cycle and keep up with the status/health of the project.
I do think if you are an experienced Hudson/Jenkins user, there may only be a couple of interesting topics (writing a plugin, the Team Concept feature that was added in Hudson 3.1).
