Andy Harris

Andy Harris earned a degree in Special Education from Indiana University/Purdue University–Indianapolis (IUPUI). He taught young adults with severe disabilities for several years. He also taught himself enough computer programming to support his teaching habit with freelance programming.
Those were the exciting days when computers started to have hard drives, and some computers connected to each other with arcane protocols. He taught programming in those days because it was fun.
Eventually, Andy decided to teach computer science full time, and he still teaches at IUPUI. He lectures in the applied computing program and runs the streaming media lab. He also teaches classes in whatever programming language is in demand at the time. He has developed a large number of online video-based courses and international distance education projects.
Andy has written several books on various computing topics and languages including Java, C#, mobile computing, JavaScript, and PHP/MySQL.
Andy welcomes comments and suggestions about his books. He can be reached at [email protected].
