today on adafruit i'm helping limor fried (first female engineer on the cover of WIRED) with 24 hours of posts with cool women doing great stuff in the world of making, engineering, science and more. she also has 10% off everything in the store to encourage giving the gift of electronics to spark imagination - http://www.adafruit.com/blog/category/random/ald/
I applaud the day, but I wish the website made it more obvious who Ada Lovelace is. I have a vague idea because I'm in the same industry, but I doubt the audience that this day is truly intended for -- the many girls and women out there who don't see the sciences and engineering as a female career -- know off the top of their head. Even going into the About page, her bio is very small.
I want to tweet/share this link but am afraid most people will click on it and go "What the?". So I'll just send the wikipedia entry on her instead.
