Country of the Week
I had a very simple "Country of the Week" webpage a while ago, and I really liked the idea but the implementation wasn't all that great, and during some recent moving around of servers and the like, it broke.
I recently developed an interest in Ruby, and used a Country of the Week 2.0 as a bit of a test project.
Obviously the webpage you're seeing is WordPress, but the weekly country entries are created by a combination of XML parsing, HTML parsing, and MetaWebLog API posting all written in Ruby.
The most impressive part, to me, is that the whole project is only about 200 lines of Ruby code.
I did run into a few problems along the way - I'll post about those shortly.
