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.
