Reduce the size of MySQL ibdata1 on OSX

So I finally figured out why my TimeMachine backups were becoming bigger and bigger, 3-4GB backing up every day when I come home from work… It seems that my MySQL database file (/usr/local/mysql/data/ibdata1) keeps getting larger and larger, unnecessarily, even if I deleted databases, tables, etc. It seems even if I only update a few rows in a table in a small database, the ginormous idbdata1 file grows and then get marks as a candidate for backup into TimeMachine. Ugh.

How to print from iPhone/iPad (iOS 4.2) via Ubuntu

I just noticed that with the latest 10.6.5 update, Apple at the last minute disabled support for printing from iOS 4.2 devices to shared printers in OSX. Instead of trying to overwrite new drivers with prerelease versions, I thought that there must be someone, somewhere out there who has figured out how to do this using the fine, free tools available to us. I like open standards, open tools, open source.
