How to Change the tech gender ratio

I'm in favour of creating a level playing field between men and women in tech (and any other X/Y you want to compare) but creating a level playing field and a lot of these measures don't seem (to me) to be the same thing.

Though in fairness this list is better than most I've seen.

Finally a good article discussing actual possible solutions instead of just reiterating the problem. I'll be adding some of these to a presentation I'm working on for this topic.

One thing the article implies but doesn't explicitly say: stop relying on hiring friends of your early employees. Chances are, your white/asian male engineers know predominantly other white/asian male engineers, so you end up not making any progress on the diversity front.
