Greg Flurry has worked as a programmer and electronics engineer for IBM. In the span of a 40-year career, his roles have included product development, product architecture, research, and client services. He achieved the title of IBM Distinguished Engineer. Greg has authored over 50 articles in IBM and non-IBM publications on topics ranging from simple programming examples to large-scale system architectures. He is an inventor, with over 30 patents. He started programming in Java from the time it became public in 1996 and, over time, wrote thousands of lines of Java code. After retiring in 2013, he started working with the Raspberry Pi, to use it as the brain in autonomous robots. As the robots became more complex, he longed for Java and professional development tools. In 2017, he began using Java on the Raspberry Pi and has done so since, educating himself on the techniques of connecting various devices to the Raspberry Pi via Java as well as identifying techniques useful in building moderately complex robotics systems.
