"gcc -O4 sends your code to Jeff Dean for a complete rewrite" is my favorite fact.

The internal version of the Jeff Dean Facts site has a picture of Jeff Dean's calculator, which has three four buttons: 0, 1, NAND, and =. +Kenton Varda links to the picture in the comments.
Kenton Varda originally shared:
"Jeff Dean puts his pants on one leg at a time, but if he had more than two legs, you'd see that his approach is actually O(log n)."

A little bit of Google culture for you...

I created "Jeff Dean Facts" as a Google-internal April Fool's joke in 2007. Apparently, nearly five years later, it has leaked to the public!

It's basically just a web site (available only on the Google internal network) like those "Chuck Norris Facts" sites you used to see around the net, where people can submit "facts" about the person, rate other "facts", and see a list of the top-rated "facts". Except they're about Google engineer +Jeff Dean, not Chuck Norris.

I actually built the site on an early version of App Engine, which had not yet been announced to the public. Even back then, while they were still busily developing the thing, it was really easy! I even helped them find a couple bugs... :)

On April 1st, I sent out a company-wide announcement of the site as if it were a new Google project. I hid my identity by attributing the mail to a mailing list with private membership. April 1st was a Sunday that year, but the next morning, at 9:32 AM, I received an e-mail from Jeff detailing how he had hacked through my servers and discovered my identity. :)

The site has continued running ever since, and hundreds of Googlers have submitted "facts". At some point, +Ari Wilson took over maintainership and expanded the site to allow you to post "facts" about any employee, though Jeff remained the main focus.

No one ever had to approve any of this. I just did it, because I thought it would be funny, and people loved it. That's kind of how things work at Google. But my little creation is nowhere near the biggest or funniest of our internal prank sites... I'll let the creators of said sites decide if and when to talk about them. ;)

Here are some of my other favorite "facts" about Jeff (at least, of the ones that would make sense to people outside the company):

"Jeff Dean compiles and runs his code before submitting, but only to check for compiler and CPU bugs."

"Jeff Dean once failed a Turing test when he correctly identified the 203rd Fibonacci number in less than a second."

"The speed of light in a vacuum used to be about 35 mph. Then Jeff Dean spent a weekend optimizing physics."

"Jeff Dean was born on December 31, 1969 at 11:48 PM. It took him twelve minutes to implement his first time counter."

"Jeff Dean escews both Emacs and VI. He types his code into zcat, because it's faster that way."

"When Jeff Dean sends an ethernet frame there are no collisions because the competing frames retreat back up into the buffer memory on their source nic."

EDIT: I posted a few more as a reply to this post.

That's really amazing -- a great way to use data that we already have to learn new things.

It turns out I'm allergic to desserts that don't contain gluten.

I am so excited to share one of the things I've been working on since I left Google: a Java library for building MapReduce pipelines in Hadoop.
