order_by('RAND()')
That might use the same seed each time.
To create, for example, a rotating home page with different content
each day, but the same after each page refresh, take today's date, MD5
hash it, and stick the hash between the () on RAND().
We used to use that with MySQL in a performance-sensitive environment,
and nobody complained about it...
