My blog and book reviews disappeared for a few days as I moved to a set of static pages that are generated up-front. cgis have never really suited me - I don't like the possibility of exploits, and I always managed to annoy sysadmins by getting the scripts spammed. So, a change of hosting gave me the excuse (or requirement, I guess :) to switch to the static approach.
So, one Lua script later and it's all back. More or less. I think there are a some bits and bobs that I'll want to improve, but basically I think this'll do.
