About the Authors

Peter J. Langley has been developing websites ever since he owned his first computer. He has been working professionally for many years as a lead web developer for various companies and industries as an employee & freelancer. As the influx of available technologies and capabilities in web browsers continues to increase, he has been fortunate enough to play a leading role in the software engineering of some sophisticated solutions, such as web-based GIS applications for Britain's mapping agency, Ordnance Survey.

Peter is passionate about the Internet, computing, and software engineering principles. He enjoys working on engaging projects in vibrant atmospheres that quickly deliver value to consumers. He has been sharing how-to guides on his website, www.codechewing.com, for many years. This is a demonstration of his personal desire to encourage people to passionately unite knowledge and thrive from each other's experiences, interests, and perspectives.

I would like to thank my partner, Alanna, for all her dependable support and positivity during the undertaking of this book.
