Cronic (http://habilis.net/cronic/) has been a real life-saver when it comes to using cron in production services. I've been using it for 4+ years without looking back.

There's also "chronic" in Moreutils https://joeyh.name/code/moreutils/ which seems to serve a similar purpose.

In the same-ish vein, may I suggest http://ikura.co for anyone wishing to link timely jobs w/ their web applications.
