I’ve turned on caching for the blog: it gets little enough traffic that 99.9% of the time I don’t need it, but I had one incident a month or so ago where traffic overnight overwhelmed the machine a couple of days in a row, requiring a reboot both times. So, since I want the blog to work and since I depend on the machine for other purposes, I figured I should turn on caching.

Please let me know if you see anything strange.

I’m using hyper-cache; another plugin I considered was w3-total-cache. Here’s a useful-sounding page on the topic.

Update: hyper-cache didn’t work so well.
