I updated the source code of my blog on github. I'm too tired to write much about it at the moment.
Suffice it to say I rewrote it all from scratch for the purpose of sharing, because lots of people were asking for it. It uses Tokyo Cabinet instead of mysql now, which is nice. I gutted the codebase so it's about 700 lines now (down from 1500, not bad). I plan to write up some posts later exploring various parts of it, for those who are interested.
Hope someone gets something out of it. Use at your own risk.
