The starting point of the track titled Think Tank - Open Diversity Summit: Why women matter? was more or less Women constitute 25 to 30 per cent of wider engineering community, but only 1/2% in Free/Open Source software development. Why, and what are the consequences?. Here are, as food for thought, some comments from ladies attending the track:
(in FOSS) women are told to start with documentation, translation and similar support activities. We must not settle for that, there's more to do.
This is really a cultural issue, quite different from country to country. I (background: highly educated Indian family) went to a software engineering college in the USA where I had zero white women as classmates.
