About the Author

John Shovic has been working with software and electronics since he talked his school into letting him use their IBM 1130 computer for the whole summer of 1973. That really launched him into his lifelong love affair with software. Dr. Shovic has founded multiple companies: Advance Hardware Architectures; TriGeo Network Security; Blue Water Technologies; InstiComm, LLC; and bankCDA. He has also served as a professor of computer science at Eastern Washington University, Washington State University, and the University of Idaho. Dr. Shovic has given over 70 invited talks and has published over 50 papers on a variety of topics on Arduinos, Raspberry Pis, iBeacons, HIPAA, GLB, computer security, computer forensics, embedded systems, and others. Currently John is proud to be serving as a computer science faculty member, specializing in robotics and artificial intelligence, at the University of Idaho, Coeur d’Alene, Idaho, and is surrounded by a bunch of students that are as excited about technology and computers as he is.

Alan Simpson is the author of over 100 computer books on database, programming, and web development.
