Last week at a convention for Python programmers in Santa Clara, California, where I live and teach, an attendee named Adria Richards posted a tweet complaining about the "not cool" jokes being made by the men sitting behind her (something about sexualized forks and dongles, which I am the wrong kind of nerdy to get). Her tweet included a photo, presumably of the offending man, which soon led his employer to fire him. Since then, Richards herself has been fired, as well as becoming the sadly predictable object of misogynist venom. Welcome to Silicon Valley's high-tech business culture.
