This was an interesting read. I found it well written and kind of sad, if optimistic and hopeful. Personally, I would love to see a lot more female developers. I am betting there is no significant difference in inherent potential talent between the two genders, so why are almost all coders I've worked with male?
I find blind technical interviewing easy because I don't usually remember new people after a few moments. My reports say "The applicant" not out of a deliberate effort to screen the potential hire's name, race, gender - anything like that but because if they left an hour ago I already couldn't tell you anything whatsoever about them besides that they've got this very idiosyncratic approach to loop structures or they seemed not to understand what thread safety means or whatever.
The only interviewee I remember at all now was a Russian woman for whom it was her first interview in the country, and her first interview in English, and my core goal for the entire time was to keep her calm enough that I could discern whether she knew how to do the job. It isn't humanly possible to stay terrified for say months, eventually she will relax if we hire her (and she did, she was fine within a week) - but she might manage to stay terrified for long enough that I can't tell if she actually understands what a compound primary key is and how these iterators I'm talking about work and if I'm not sure then hiring her would be a big risk.
