Though internet spreads the word at lightening speed, but i came to know about Ada Lovelace Day 3 days late. Pardon my ignorance.
To quote from website http://findingada.com/
Ada Lovelace Day is an international day of blogging to draw attention to women excelling in technology
Who was Ada ?
Ada Lovelace wrote the world’s first computer programmes for the Analytical Engine, a general-purpose machine that Charles Babbage had invented.
The computer language Ada, created by the U.S. Defense Department, was named after Lovelace
The name that promptly came to my mind of woman in technology i admire is :
She was founder and lead developer of Pownce (a twitter clone), She has contributed to OAuth and many more open source projects and another important thing she writes code in python :).
Nowdays she works with SixApart.
Its not too late to celebrate i think, spread the word and tell the world about women you admire in technology.
