"Enlightenment Now: The Case for Reason, Science, Humanism, and Progress"
Is the world really falling apart? Is the ideal of progress obsolete?

This is a shameless copy of a more complete review I blogged about:
Unsurprisingly, puppet cannot be run by itself. The first chapter points out that you need to also install Apache and Passenger. For a unix/linux machine, Apache is probably already present. So you just need Passenger. Unfortunately, there are dependent packages. Namely Rails, Ruby and MySql. Apache is recommended by Arundel, instead of sticking with the default puppet web server which he says is too slow.
Puppet as you will see is run at the command line. Serious sysadmins should prefer this to a slick GUI, because the text based input lends itself to crontabbing (scheduling under linux) and also to a modular format in line with other unix based packages.
It is indeed possible to program in puppet. It comes with what seems to be a simple scripting language that, above all, has conditional statements ("if"). The code snippets are deliberately easy to follow. Your usages might end up with far more intricate logic. Puppet also comes in a modular form. So that 3rd parties (you?) can add to it. As inspired by the success of packages like Apache. The text explains how. Somewhat non-trivial, but it certainly looks possible. Speaking of Apache, one section of the text involves writing a module for it to interact with puppet.
The best part is the way each content is organized. Each topic is distributed into following sections "Getting ready", "How to do it", "How it works", "There's more", and "See also". This made things detailed and clear for me.
Even if you have done puppet set-up in this book you might find some useful info which can make things easier or better. For example, this books, talks about various puppet.conf parameters (as common as modulepath and as unknown as usecacheonfailure, ).
Another good thing which I felt that apart from managing Application, Packages and Virtual resources, this book covered Reporting and graphing. Though I haven't tried reporting and graphing yet, but courtesy this book I might try that soon.
The only 2 things to keep in mind regarding this book. First, it is not for beginners and demands some understanding of Puppet and Linux (though author has mentioned in the book, but thought you should be aware). Second, it is not purely a "How do I" kind of book.
I highly recommend the book for anyone that wants to get a better handle on common problems.
