Margaret Hamilton: she is quite impressive

She's quite awesome.

but famous is basically just luck at the right time, I don't tend to be a fanboy ... I prefer to see humans and possibilities to learn from them. :) There are so many impressive achievements from women and so many impressive women everywhere same goes for men but we're currently statistically overpopulated .... ;)

Sandi Metz is missing in that list: twitter.com/sandimetz

Her speeches are always entertaining, even though I don't care about Ruby.
