On a sunny day in July, some 35 budding computer science students sat in a large room with beige walls and blocks of tables arranged into nine group work stations. The room was a temporarily commandeered art gallery in New York City, directly underneath the city’s High Line park, in a now-gentrified neighborhood that was once the seedy heart of Bohemia. Below the tables snaked power strips secured to the floor with electrical tape. Above them, a sea of adolescent faces — overwhelmingly male — stared intently into their MacBooks, typing and occasionally reaching for bowls of snacks that seemed rarely out of reach.
