It’s 3am in Kiribati, 2am in New Zealand and 1am in Fiji, which means it’s now 24th March and Ada Lovelace Day has started!

Some people have already blogged, and we’re beginning to see posts trickling into our Ada Lovelace Day Collection mash-up. We have pins on our map from New Zealand, Israel, Sweden, the Netherlands and the UK! When you have published your contribution, please add it to our database.

You can view the posts on the map, in a list, by language, or by subject, i.e. the woman or women blogged about. It’s going to be fascinating to see how this shapes up over the course of the next 47 hours – due to various international date line shenanigans, one day lasts 50 hours online!

In other news, Ruth Wilson of the UK Resource Centre for Women in Science, Engineering and Technology emailed me to let me know that their guest blogger from today is the great-great-great niece of Ada – Honora Smith, Operational Research and Management Science at the University of Southampton.

If you’re going to the Game Developers Conference, look out for Celia Pearce and her colleagues at Ludica who have created an Ada Lovelace badge that they’ll be giving away throughout the event. The badges (or buttons, if you’re American!) are free but they are accepting donations to cover the cost. You can also buy online.

NetBehaviour are inviting all women who work in media arts and net art to join their email list for a week between 23rd and 30th March to talk about inspirational women. At the end of the week they will collate all of the posts in the thread and feature them on Furtherfield.org.

And there’s more from the Science Museum on Ada Lovelace Day:

It’s just one week now until Ada Lovelace Day, and we have some great news to announce.

Ada Lovelace Day at The Science Museum
As you may know, The Science Museum has a reconstruction of Charles Babbage’s Difference Engine on display, which is worth a visit on its own. But on 24th March the museum is putting on a special treat: Ada herself will be will be walking the floors throughout the museum, telling her story.

Visit the Science Museum website for more information, especially on the day as an article about Ada by Tilly Blyth, the computing curator, will be featured on the front page.

Computer Weekly
I’ve been chatting to the lovely folks over at Computer Weekly, who happen to have an issue out on the day itself. They are going to be featuring Ada Lovelace Day in the magazine, and will be blogging as well. So take a look if you see it on the news stands, or visit their website and the WITsend blog.

Summer events with Nesta
I am particularly pleased to be able to announce that Nesta, the National Endowment for Science, Technology and the Arts, is going to be hosting a series of events for women in technology over the summer. The first is scheduled for June 10th, so get that date in your diary! We’ll announce more details slightly nearer the time.

Ada Lovelace Day on Flickr
If you’re doing something on the day, or what to post related photos, we now have a Flickr group you can join.

Meanwhile, we are still working on our mash-up which will let you add your blog post, and will send out the URL for that as soon as we have it, although details will of course be posted here.

I hope you’ll agree that it’s looking like the 24th March is going to be a fun day. I’ll be going to the Science Museum to see Ada, so if you see me there please do come and say hello!

Ada Lovelace Day itself is fast approaching – we’re just two weeks away now.

Please remember that you can talk about your tech heroine in any medium you choose: blog, video, podcast, newspaper column… the choice is up to you. Your contribution can be as long or as short as you wish, in any language, and can be published any time on 24th of March, regardless of time zone.
