In working with women in open source, the Ada Initiative found that many women are reluctant to post their code publicly when they are first getting started in open source software. This reluctance has good reasons behind it: fear of being told they are bad programmers, fear of being publicly mocked or harassed, and even fear of losing job opportunities. All of these are greater risks for women on average than men. But the best way to get better at programming is to collaborate with and get review from other programmers, which is far easier to do with a shared repository like those provided by GitHub. Unfortunately, private repositories are too expensive for most women just getting started in open source software.
We went to GitHub with our dilemma, and they immediately offered us unlimited free repositories on the Ada Initiative GitHub account.
