How to Use This Book

You can read this book from cover to cover if you like, but each hack stands on its own, so feel free to browse and jump to the different sections that interest you most. If there's a prerequisite you need to know about, a cross-reference will guide you to the right hack. We've also tried not to be shy or "our book"-centricif there are other books on a topic that we particularly like or find valuable, we've put references to them at the end of the hack. Some of them are other books from O'Reilly, but we're not recommending them for any reason other than the fact that we've found them to be useful. We only recommend what we believe in.
