What's the deal?
To quote the site:
Ada Lovelace Day is an international day of blogging to celebrate the achievements of women in technology and science.
Ada Lovelace was a 19th century mathematician who wrote the first computer program for a machine called the Analytical Engine invented by Charles Babbage.
It takes place on March 24th and provides an opportunity to blog about and share information about our science & tech heroines. It's just over a month away, so you have plenty of time to do some research and write about a pioneering woman.
