It blows me away that "The Jargon File" is not required canon. Well, it can be anachronistic and old-school-nerd-bro coded, but there's some primal stuff in there http://catb.org/jargon/html/
I'm trying to maintain that the nerds of yore and the bros* who invaded in the 2010s are different groups -- in which case "old-school nerd bro" would be a contradiction in terms -- but alas "bro" has simply come to mean "male", and, to the English majors writing the newspaper articles, "they all look the same". So maybe I need to give up.
* etymology: "tech bro", in analogy with "finance bro", which originated because fraternity brothers from top schools used to go into finance, but then migrated into Tech around '08. Associated stereotypically with developed pectorals and polo shirts with popped collars. Close to the "Chad" archetype, but with some light granola/yoga overtones.
