About the Book

Human brains are funny things. At the end of the day, our brains are still wired the same way they were when we were cavemen trying to survive in the wild. Anything relevant to our immediate survival tended to "stick" in our brains, and anything not relevant tends to slip past. Tell a child, "don't touch that hot pot on the stove!" all you want to, they're still likely to touch it—once.
This book is the hot pot on the stove. It's a collection of mistakes, and an opportunity to solve them, albeit without burning your fingers.
In this book, I've collected edited versions of PowerShell questions and "broken" code, and in each chapter I'll present one. You'll take the time to read the code, figure out the problem, and try to solve it. Then, I'll present a solution, along with a detailed explanation of not only what was wrong, but why.
This book is not a how-to, and I presume that you already have a decent amount of basic PowerShell education under your belt. This book is not about how to make Active Directory work, or Exchange Server, or SharePoint Server, or anything else; this is about PowerShell. So you're going to see problems that relate to the core of how PowerShell works. Many of these problems spring from "gotchas" in PowerShell, while others have their origin in very common misunderstandings about how the shell works.
If you feel that you learn best by getting your hands dirty, making mistakes, and figuring them out, then this book is for you.
And if you've ever wondered, "do I really know what PowerShell is all about?" then you can consider this book to be an ongoing quiz of sorts. Each chapter offers a new opportunity to test your PowerShell mojo, validate what you know, and perhaps pick up a new trick or two along the way.
NOTE: This is a "continually published" book, and it is open-source. All proceeds (whatever you set the price to when you buy the book) are donated to The DevOps Collective's scholarship and other nonprofit programs.
