That's one of the many many reasons I miss my dad so much. He went straight from MIT to GenRad circa 1970. I didn't start doing software till 1998, but we had some years of overlap -- and it was profoundly gratifying to connect w/ him on engineering topics. The learning was even bidirectional tho I'm sure I got more out of our pseudo-professional interactions than he did. Sigh. I really miss him.
