I'm not an HN user because this website sucks, I was informed that someone shared my post here by email so I went to check it out and remember why I don't use this site. You're a woman-repellent and this place is full of the likes of you, that's the reason you don't see many women here, and it's the same reason you don't see women in real life.
In summary, since I know you can't handle too many words and summaries are all you read: Go fuck yourself.
So of any statement of "<X broad group> just wanna have fast mpmc queues" should be obviously taken as a parody.
At which point... why rail on this?
Yes, but even of those who do care the vast majority will obviously be male.
I definitely know some girls who'd love this, and see this as having fun.
That's hard to believe. Then you should know at least an order of magnitude more "boys" who would love this: At an estimated 95% male ratio on HN, 20 times as many. If the "some girls" you "definitely" know are 3, then you would be expected to know about 3x20=60 males who are interested in "fast MPMC queues with bounded waiting", which sounds about equally hard to believe.
