As a woman in tech I felt angry reading this history, but I'm not surprised by the information. It covered countries outside of the US which I appreciate because many of the resources I read on the tech industry generally tend to be US-focused, which is like another planet compared to Europe.
I'm only giving this 4 stars as I'm not sure I agree with the conclusion that the nerd culture is not driving women out of tech. The nerd culture is immature, pervasive, creepy, hostile, rationalised by pseudo-intellectuality, and yet managers let these people dictate the hiring practises which thus fuels the expectation that we spend all our spare time programming until we become an "asocial, malodorous, pasty-faced monomaniac with all the personality of a cheese grater"** because obsessiveness is the signifier of technical prowess, apparently. It's like a cult. Don't even get me started on the totalitarian dictatorship of Scrum.
I like that it is a collection of research by different people. I especially enjoyed chapter 11 "Programming Enterprise" which focused on the success stories of various female software developers.
