Did you know that you can enable access logging on S3? Did you know that you can add arbitrary metadata to objects in S3? Did you know that you can serve compressed content from S3?

The S3 Cookbook, an e-book written by Scott Patten, has easy-to- follow recipes to do those and about 60 other things (including one that I contributed for backing up a MySQL database to S3). In addition to the recipes, it also has chapters on S3's architecture, authenticating S3 requests, and an overview of the S3 API.

You can checkout the full table of contents and download a sample chapter.

It's published on Sopobo, a new platform for authors to self-publish technical books (that also happens to be created by Scott!). Sopobo includes tools for readers to interact with each other and with the author. If I were writing a book that I planned to shop around to a few publishers I'd seriously consider putting it on there first to get some feedback (and make a few bucks) before it got picked up.
