Description:About the Author Albert Sweigart (but you can call him Al), is a software developer in San Francisco, California who enjoys bicycling, reading, volunteering, computer security, haunting coffee shops, and making useful software. He is originally from Houston, Texas. He finally put his University of Texas at Austin computer science degree in a frame. He is a friendly introvert, an atheist, a cat person, and fears that he is losing brain cells over time. He laughs out loud when watching park squirrels, which makes people think he's a simpleton. His childhood Nintendo habit led him into programming and all the joys that come of it. His web site and blog are located at http://coffeeghost.net
