I've been a Silicon Valley software engineer for 15 years. I see no disparity of gender that's a concern.
I work in a team of 6. We just hired a senior engineer, a woman. Of the 9 people I interviewed, I only recall 2 men in the interview. In our team, there are 2 men, me and another guy in another so called discriminated class - age. He's 53. Our entire dev team is about 50/50 and might even be tipped to the female side.
When we went to universities to screen for interns, no identifiable difference at one I went to at San Jose State.
Now, there is a disparity in American v. Indian (and some Chinese and Russian), but I don't think it's anyone's fault. Those are the people looking for the jobs.
Granted I have seen some companies that put their white male faces from a Portland company right up front, but my personal observations in Silicon Valley are quite different.
