To get the most out of this book

To get the most out of this book, I highly recommend that you work through the programming exercises in each chapter thoroughly. Each exercise is meant to lay a solid foundation for more advanced exercises, so it is critical that you follow each and every step in the programming exercises. I also recommend you be adventurous. Different technologies and techniques discussed in each chapter can be mixed with those from other chapters. A technique used in one chapter is not meant to be exclusively applicable to that specific chapter. You can apply the technology and techniques learned from one chapter to other chapters, so it will be beneficial for you to go through the examples from the beginning again and try to mix up different techniques learned from other chapters when you finish this book.
