YAML Cookbook 3
While researching what some of the YAML syntax was doing in Ben Bleything's article on DRY'ing up your database config, I ran across the YAML Cookbook. I've only ever used YAML for my database.yml and test fixtures, so I was really surprised to see the power YAML affords the Ruby programmer. Check it out, you will find a few things useful in your fixtures and I'm sure other ideas on it's use will come to you as you see how powerful it is.
