It's Ada Lovelace Day. A day to celebrate women in science, technology, engineering and mathematics.
All of the women mentioned in the title of this post are women I've worked with and for. All were programmers, testers, writers and designers who helped create software I've worked on. They were few among a tide of men.
It made a difference to have that diversity. Thanks for being there!
PS My keynote from OSCON 2011 about diversity and strength.
