"Ada Lovelace Day is an international day of blogging to draw attention to women excelling in technology. Women's contributions often go unacknowledged, their innovations seldom mentioned, their faces rarely recognised. We want you to tell the world about these unsung heroines. Whatever she does, whether she is a sysadmin or a tech entrepreneur, a programmer or a designer, developing software or hardware, a tech journalist or a tech consultant, we want to celebrate her achievements.
"It doesn't matter how new or old your blog is, what gender you are, what language you blog in, or what you normally blog about - everyone is invited to take part. All you need to do is sign up to this pledge and then publish your blog post any time on Tuesday 24th March 2009. If you're going to be away that day, feel free to write your post in advance and set your blogging system to publish it that day."
