@ottocrat I'm from roughly the first generation of software engineers who didn't get an Electrical Engineering degree, which was once the only relevant discipline the universities knew about. So occasionally I'll find myself in the lab trying to solder together some a cable end or something in order to get some vintage hardware working as a reference, and a slightly older bloke will watch me for a moment in growing dismay and finally say "for god's sake didn't anyone teach you how to solder?", gently move me aside and with a deftness I could never hope to emulate produce this seamless thing in seconds...
