I decided to learn Clojure (and therefore ClojureScript, since the two intersect significantly) by doing. Who'd ever blame me with that?

Scalr

Cron Jobs Are Hard To Distribute

Watch out when scaling out instances with cron jobs on them. Cron jobs aren't designed for the cloud. If the machine image holding your cron job scales out to 20 instances, your cron job will be executed 20 times more often.

This is fine if the scope of your cron job is limited to the instance itself, but if the scope is larger, the above becomes a serious problem. And if you single out a machine to run those cron jobs, you run the risk of not having it executed if that machine goes down.
