6 do not have a C.S. degree,
2 have a liberal-arts degree,
1 has an engineering-related graduate (and post-graduate) degree,
4 did not finish college (or did not attend), instead opting for entering business,
2 are women (because I know someone's going to ask),
5 are over 40.
This deserves some additional commentary, to which I will have to attend later.
(I'd been thinking that of the best engineers I know, the majority did not finish university or did not attend. I'd also thought that many, or most, of them had some sort of liberal-arts study. I quickly compiled a list and derived some elementary statistics in order to do a quick analysis of my supposition. More on this later.)
