I was originally a developer from Des Moines, IA. Moving to Boston, and Los Angeles after that I was surprised to learn one of the early real time operating systems, called os9, came from a company from Des Moines in the 80's. That OS was used on the original generations of ATM machines deployed world wide. I worked on early real time streaming during the early 90's in Los Angeles, and Des Moines was one of the better places for locating experienced real time developers. A while ago I heard Iowa in general and Omaha, NE have growing tech hubs.
