Ada Lovelace Day is an international day of blogging (videologging, podcasting, etc.) to draw attention to the achievements of women in technology and science.
Ada Lovelace was one of the world's first computer programmers, and one of the first people to see computers as more than just a machine for doing sums. She wrote programs for Charles Babbage's Analytical Engine, a general-purpose computing machine, despite the fact that it was never built. She also wrote the very first description of a computer and of software.
The first Ada Lovelace Day was held on March 24th last year and attracted nearly 2000 signatories to the pledge and 2000 more people who signed up on Facebook. Over 1200 people added their post URL to the Ada Lovelace Day 2009 mash-up.
The goal of Ada Lovelace Day is for people to pledge to publish a blog post about a woman in technology or science whom they admire on Ada Lovelace Day, March 24th 2010. You can make your pledge at http://findingada.com/.
And if you'd like to share your tech heroine and hear about other people's, there is an Ada Lovelace Day event in London on March 24 at the Centre for Creative Collaboration.
