lgreco asks: "I've been thinking about the similarities between the community of early ham radio operators and software developers. Both communities produced a lot of useful technologies that found applications beyond the scope of a 'just a hobby'. Ham radio operators built their own equipment and experimented with modulation and propagation techniques. The results of their efforts today are used in a variety of radio communication applications, from cell phones to marine radios. Similarly, hackers developed concepts of computing that are now universally accepted tools of productivity. Both communities share an enthusiasm for technical creativity and up until recently there was even some overlap between the two groups. Are there any interesting stories about the creativity of either groups (that relate to the other group perhaps) that should be recorded and documented?"
