I worked out that there were 38 women and 12 men for the first session
of the LinuxChix miniconf. In the question time, it came out that
the FOSSPOS study (I've yet to find it on the intarweb) showed that
FOSS and Linux has an order of magnitude
fewer women compared to
the rest of the IT industry. And yet, when I asked my question "why is
this?" Val Henson pointed out to us that, even with that
proportion of women in the room, all of the questions up to and
including mine had been asked by men.
Ouch.
