Ada Lovelace Day: Women in PHP

This morning, as the first Ada Lovelace Day posts started rolling into my Google Reader, I found out about the whole concept of Ada Lovelace Day. I immediately pledged to write a post, because I think it is a good idea to give "women in technology" some attention. I would wish it wasn't necessary, but we're living in a world where this is still necessary. I'm going to pick two "heroines" though, instead of one.
