In August 2007 a hacker found a way to expose the PHP source code on facebook.com. He retrieved two files and then emailed them to me, and I wrote about the issue:

http://techcrunch.com/2007/08/11/facebook-source-code-leaked/

It became a big deal:

The two files are index.php (the homepage) and search.php (the search page)

#
# this module encapsulate the interface expected by DelayedJob, and Resque -
# if you use it your app will not need to change if you change background
# processing systems.  it also centralizes and makes easy to test all
# potential background jobs independently of your preferred system.
#
# all jobs are stored in the db, but a queueing system, like resque, is used
# to run them in the background.  this way the job class can support a rich
# query interface and persistence regardless of the background processing
# system used.

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs
