The article bounces around to touch so many different social issues its nearly incoherent. Regarding the main point I think it's a non issue. Companies are only interested in hiring OSS contributors to get a feel for their work. There are many other ways to do this. For example since a lot of my work is visual I maintain a demo reel. For others it may be articles you've written or even Stackoverflow contributions. It…
Lucky for you that you can show your work to people outside of your company, right? > Also the author says she knows "many" women who have had trouble contributing to OSS based on how they were treated. GitHub should make it easy to provide examples of this right? Now you're being deliberately obtuse. Not everyone uses github, and not all communication happens through github.
It's also important to apply Hanlon's Razor [2], "Never attribute to malice that which is adequately explained by stupidity.". Sometimes that stupidity (or ignorance) is the person rejecting your contributions, but it could also be your own stupidity (or ignorance). I have found that most people who try to contribute to open-source and fail have never read esr's classic "How to Ask Questions the Smart Way" [3]
If you eliminate all identifier's of gender by using non-gendered handles and initials for your first name in your git config, you can safely look for other explanations for your difficulties contributing to open-source besides your gender. It's called applying the scientific method. If you hypothesis is "I'm having trouble contributing to open-source because of my gender", you should obfuscate your gender in your contributions to control for that variable. Once you eliminate it as a possible confounding factor, you're free to come up with alternative hypotheses for your difficulties.
Personally, I don't have my name, gender, or location on my github profile. It's a community for contributing code, so all such metadata is irrelevant. I'm genuinely curious what percentage of github users cannot be determined to be male or female (which is a figure the author did not cite).
