The fact that there are not so many female developers ine the FLOSS world is clear for everyone. Reasons? Well... complex. Apache has now a list that is intended to help them start, as ZDNet writes. It's third such initiative I know, after Debian Women and KDE Women.
I have mixed feelings about such initiatives. They, however, help those with not enough self-confidence to jump into FLOSS development on their own. I'm wondering about the effectiveness, but it's very very hard to check.
