I have a SQL query that examines an entire column (right now 25,000
rows, but growing fast), it finds the top 50 most common elements in a
column. To reduce load, I want to execute this script only once a week
instead of every time the page is loaded.
What is the best way to do this? Just run a cron job that executes a
Ruby script once a week? Or does MySQL have something built in for this?

I have the same situation with scripts, cron is a right choice.

What exactly do you mean by "every time the page is loaded"? Is this some kind of web application? Are you using some kind of framework?

I don't know MySQL - it probably has. An alternative approach is to use cron to schedule your script and have the script write the result of processing in a table inside your DB. The "page" can then read from that instead of triggering the complex process every time. HTH
