Have a Look at GitHub's Backend Magic

[geoff-codes]

Spin up an instance of one of the GitHub Enterprise AMIs — they're public, easy to find.

SSH in, then use my little script here: http://git.io/XKINlw

...which de-obfusacates everything in /data, the code that powers GitHub.com and GitHub Enterprise.

(You can then make a tarball and copy it locally, and terminate the instance.)

I sent this to the GitHub security team a week ago. The response I got was basically "yeah we know, its whateva".
