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)

/**
 * Builds a horizontal masonry in whats possbily (i haven't researched
 * the techniques) a crude manner.
 * Fits elements into columns if there is room and sets the width of
 * the container element to contain all the columns.
 * 
 * Known Issues:
 * - Does not do anything clever for elements where height exceeds 
 * window height (probably just gets chopped off if overflow: hidden)
 * - All elements are expected to be the column width
