We'd be more than happy to host a SHDH. Shoot me an email at dr@fb.com.

Allow me to say this is why I love HN. :-)

Email on the way!

It's under "Account Security" on https://www.facebook.com/editaccount.php?ref=mb&drop.

Hmm, does anyone else not see it there? Perhaps they're still rolling it out.

Not there for me. Looks like a slow roll out.

There's definitely a desire to build out more environments. Just decided to get it up and running on x86 first with both 32 and 64 bit architectures on a variety of Linux distributions.

This headline is actually pretty misleading. From what I've seen of the project, it is not about the government issuing online identities. Rather they've realized that people already have identities from services like Facebook and Google as well as banks.

This project is aimed at making it possible for people to interact with government agencies using identities they already have. Some interactions require very little security and knowledge of who a person is (leaving a comment here for example) while others (paying your taxes) require quite a bit.

Is it really in the best interest of collecting taxes to defer authentication (and even authorization) to a third party such as Google, or even banks?

I interact with the IRS once a year having to remember a short PIN I created years ago and can't figure out how to change. My bank has a very strong knowledge of who I am partially via http://en.wikipedia.org/wiki/Know_your_customer and because I login to it on a much more frequent basis.

It isn't that my bank would change the role of the IRS, but I'd login to the IRS using a strong identity issued by my bank versus this silly PIN I use today.

...or you could use the mail.

A bit strange though when comparing the pie chart with the other graphs.

http://www.facebook.com/notes/facebook-engineering/the-under... talks a bit more about this decision.

That comment is in Primer which is a very small piece of JavaScript loaded at the beginning of every page.

Thanks, did FB ever release anything more from Primer? https://gist.github.com/376039

Or is this it? I didn't see the comment.

That it is, it just excludes the comment at the header. It has actually changed a bit since then, but that is still pretty much it.

As a number of other people have pointed out, we (I'm an engineer at Facebook) use http://www.java.com/js/deployJava.txt which Oracle has released under the BSD licensed. One of the requirements of the license is that their copyright header is preserved when distributing the source code.

Beyond the script from derferman, you can download a copy of all of your photos (and videos, wall posts, etc) as a zip file directly off of Facebook from the bottom of your Account Settings page.
