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.

On the day, please use this to tag on your post, video, podcast etc.:

• ALD09post

And if you’d like to link to us, we’re on the web here:

• Pledgebank
• Twitter
• Yahoo Groups
• Facebook

We’ve some exciting last-minute news brewing, so please do keep an eye out for our next announcement!

In the meantime, why not pop along to the Guardian Tech Weekly podcast to hear Aleks Krotoski, Emily Bell, Jemima Kiss and I talk about women in tech.

Finally, we currently have 1386 people signed up to the pledge. Can we hit 2000 before the 24th? Please do continue to spread the word and see if we can’t find another 614 people over the next two weeks.

I’ve been thinking about how we might keep track of all the Ada Lovelace Day blog posts, podcasts etc., and have had a number of emails from people thinking the same thing. Initially I was thinking perhaps a Delicious tag and an RSS feed, but surely there’s a more visually exciting way to do it than that!!

So, what about a map mash-up? Can we set something up so that people can locate themselves on a map, link to their post and state who they’re talking about? I think the minimum info that I’d like to collect would be:

• geolocation
• language
• URL for blog post, video, audio, etc.
• name of blog or blogger
• name of woman featured

What would be the best way to do this? And is there someone out there willing to build something for us? It’d be good to have a permanent archive of the day and a visual representation of all the posts. Please use the comments to discuss your ideas.

The last couple of weeks, since launching Ada Lovelace Day, has been bonkers. I originally worried that we wouldn’t find enough people to sign the pledge, but it took just seven days to get 1000 signatories and we now stand at 1183. That’s fabulous, but we’ve got 62 days left before the pledge completes. Surely we can find another few thousand people willing to sign up?

I want to make a really big splash on 24th March, so even though the pledge target has been met, let’s keep on spreading the word and recruiting new bloggers, podcasters, video bloggers, Seesmicer, Twitterers and, hey, even journalists!

Here are a few things you might like to do:

• Blog about Ada Lovelace Day: Dozens, possibly hundreds, of people have already written about Ada Lovelace Day, for which I’m very grateful. But if you haven’t yet mentioned it, please do.
• Put the pledge badge on your blog.
• Tell your friends. If you know someone who might be interested, let them know!
• Tell your local media outlets. Can’t hurt to try and get a bit of press, can it?
• Invite your Facebook network. There’s an event page on Facebook, but we also need people to sign the pledge as well.
• Go crazy mad with the social bookmarking: Digg it, Reddit, Delicious it, just get it out there.
• Twitter a link: Let’s have a big push on Twitter to get the word out to our communities!

How else can we spread the word? Let me know in the comments, and let’s get as many people as possible to join us all on Ada Lovelace Day.

We are just 95 signatories off reaching our target of 1000 people, all promising to blog about a woman they admire on 24 March 2009. I had originally been a bit worried that we wouldn’t see 13 people per day sign up, but the reaction to the pledge has been just awe inspiring. Now my aim is to get 1000 people within the first seven days – which means that we have to reach our target by 10pm tonight, GMT.

If you haven’t signed the pledge, please do. If you haven’t blogged about it or Twittered about it yet, please do. We have less than twelve hours to hit the target!
