On: I, Lady Coder, will probably never go to a Hackathon.

Yes, because she says "I, lady coder" in the title. This implies that she's speaking for women. If she wasn't, then she shouldn't mention her gender.

My point stands. She identifies herself as female for the purposes of giving a data point and explain why she wrote the post in the first place.

The author left a follow-up comment:

my point isn't that that female coders aren't interested -- it's that I am not interested, and a lot of day-job-coders aren't interested

So regardless of your interpretation, she wasn't trying to speak for all women. Personally I think it's a stretch to draw that conclusion.
