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:

It became a big deal:

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

Divisibility

整除的性质:

Lemma 23. The following statements about divisibility hold.

If $a\mid b$, then $a\mid bc$ for all $c$.

If $a\mid b$ and $b\mid c$, then $a\mid c$.
