When I spoke with a female intern this summer, she recounted how, in 2006, the GNOME Project, a free and open source software project, received almost 200 Google Summer of Code applicants. All of them were male. When GNOME advertised an identical program for women, emphasizing opportunities for learning and mentorship instead of tough competition, they received more than 100 highly qualified female applicants for the three spots they were able to fund.
