I've worked with women my whole life in tech. I sit right next to one currently and she's an awesome talent and from what I can tell is an equal member of the team. I do see some passive things like their opinions not being heard as much and I think that has almost as much to do with how they speak (not with confidence) as it does their gender. I try to make a point to listen more carefully and help promote the ideas of my female coworkers when they are good. I've never seen nor heard of any of the more overt things mentioned in the blog post like being groped or anything of the sort. Probably the worst I've heard is the guys lamenting that there are no women on the team and commenting that they can't find women interviewees that have the skills required for the type of project we were doing.
