I worked my way through Task E: Checkout in the Agile Development Book today. I find myself increasingly confused by what is going on behind the scenes as my depot project gets more complicated.

Since I got a Mac Mini over the holiday break, I decided that I might as well start over using the new computer to learn Ruby. Of course, this meant installing the Ruby development environment on a Mac after finally getting it to work on my PC.
Ruby is amazing for handling databases. I couldn't believe how easy it was to create an admin interface for my test demo application. The only problem I ran into today was adding a column to the database. I couldn't get the database table to updated after adding a price column. I finally realized that it was my fault for not reading page 2 of the book more carefully. Since Agile Web Development is written for Rails 1.2, I needed to install the Rails framework snapshot for the time being.
