I have worked in industry all my life only swaying towards lecturing in the late 90’s when asked to present a journal on electronic commerce. My own education was completed on a part-time basis, starting with electronics & computing, business (MBA), and finally a PhD (focused on EDI). I still working in both industry and education employing what I teach.
Electronics & computing and the uses of in both a hobby and business environment.
Computing and the outside World (IoT), Hardware and software system integration. Embedded systems for daily use (new tech and using old tech in a new way).
