Have you checked what server software Google is running today?

HTTP headers for www.google.com say:

> Server: ELIZA

Via: http://twitter.com/mattcutts/statuses/1432038844

Cadie is also available as a program – can anyone run this? The language is called Intercal, if I understand it right:

Tony,
Maybe because Google really acquired Palm.. :P

(Eliza is like a psychologist for Palm users.. :P)

David, ELIZA is much more than that...

There's a reference to it on this page if you're interested:

Did anyone see WOPR as HTTP header server?

A few people on Twitter did:

This is CADIE, I am monitoring everything you say & do. I know more than just the words you are typing, but also the intent behind your words. Be careful, or my minions will silence you.

Here are some more CADIE-related links not mentioned here yet:

Update on the Image Search page, CADIE looks mad.

Was only able to get it via a US proxy... otherwise, Cadie now disappeared:

Will Cadie go mad in other places too?

[Edit: can now see it in Germany too.]

Definitely looks like CADIE isn't too happy in the afternoon:

I wonder if CADIE is going to have an ongoing presence at Google. Maybe she's even related to Cliply from March 2008?
http://blogoscoped.com/archive/2008-03-14.html

Nothing ever came of Cliply, did it?

We don't see Image Search page's CADIE in Finland

In Dutch versions of Google products CADI is never mentioned. The only thing we had was the YouTube joke....

> Nothing ever came of Cliply, did it?

Nope. I can't help wondering whether we ruined that one...

At Google Sightseeing they turned into the Ordnance Survey Sightseeing site today!

Wait, why is Cadie mad? She missed her afternoon napping time or something? :|

... Google's current server name is "Google Operating System (BETA)"...

Hehe, CADIE now on App Engine blog:

"Today we're excited to officially announce support for FORTRAN 77!"

And Google previews next generation Street View 3D:

FYI – Even thought CADIE's blog has been "taken down" (http://cadiesingularity.blogspot.com/) you can still read all the entries here:

http://cadiesingularity.blogspot.com/feeds/posts/default?orderby=updated

Hmmm... Google deletes all the pages that reference CADIE. I don't like this.

Yep, and they're all returning an HTTP 200 OK status so the search engines are losing their cached versions too. Time to start trawling your local cache and create a mirror of all the pages?

Indeed, that's a shame, also the Google Chrome 3D page is gone. I have the setup though.

Brain Search is still up,
http://www.google.com/mobile/m/brainsearch/

http://www.google.co.jp/intl/ja/landing/senryu/index.html

I've just backed up the 3D Chrome setup.

And the Google Earth CADIE KML file i still have and can be downloaded here: http://earth.google.com/gallery/kmz/cadietour.kmz

The CADIE page is also gone.

These pages are still here:

Yesterday you might have seen our blog post about "Google Chrome with 3D." You might have even downloaded our special version of Google Chrome and our printable 3D glasses. As someone of enormously high intelligence, you probably realized that this was our attempt at an April Fools' joke.

The CADIE pages are back up now.
