It might be the case that this strikes me as a man's writing just because there are more men in tech, but I don't know that it's the incompetence per se. It's sentences like, "Often in this situation I’ll break out something like the Saxo board, with an FPGA and a thick USB 2.0 pipe," that I just have a very hard time imagining a woman writing. In the same way that a woman couldn't have written Cory Doctorow's Little Brother. I think it's the implied, "I'm so cool because of all my techno whizbangs." But it's even in the non-tech writing: "In other words, I wanted to hack something I actually use: my vagina." is so horrid that I have to believe that even the bona fide female Xeni Jardin, lover of techno whizbangs, would have a hard time accepting it as... womanly... to talk about "using her vagina".
My girlfriend has screamed at me more than once over the futility of sharing my thoughts with "you people" who "will never understand [my] perspective", but at least a few here are kind, even if I'm not, and for that I'm grateful.
