Try getting a technical job as with a popped collar. Even if you are technically very proficient, there is stigma and distrust from people like the author of the article
Most of those "drunk frat boys" someday grow up and get jobs somewhere. They're always the rare guy that everybody at their workplace hates, so I don't think anybody will ever legitimately associate programmers with party dudes. If anything, we're all lumped together as smug assholes who love to complain about other men's lifestyles.
I don't really care what someone does in their free time. If they can code well and they don't get in the way of my job, then they're fine. If their idea of a good weekend is going to a party with naked women, then I don't care. Claiming they're sexist is putting women on a pedestal, because some women chose to go to a party to meet such guys, and they're going to go back to their workplace and brag about the hot guys they saw at the party.
I'm not even a "brogrammer" by any means, but I hate how much male programmers go out of their way to claim to be morally superior.
The tech world is a meritocracy. If 'brogrammers' can live up to the standards then why shouldn't companies hire them? The question is will they make tons of sexist comments at work and make people uncomfortable? You have to hire a few and find out.
Kids these days...
