// i often do this just so i can make a variable a constant let and not a var;
// with a var I could just use a switch, but it's better to have a let when possible

// how to make this prettier?

                someBoolExpression ? 1 :

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:

http://www.techmeme.com/070812/p1#a070812p1

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