Last week I spent a few minutes over lunch cleaning up the code behind killthe.net and posting the results to GitHub.
There’s nothing terribly interesting about it if you’re already familiar with the Sinatra micro-framework for Ruby, but I think it’s a decent starter app for someone new to Sinatra or Rack who wants to see how some things fit together.
As described more fully in the README, the app simply checked the Delicious.com “killthenet” tag feed for new entries and adds them to its database. The web interface is just a simple listing of those entries, with minimal search available as well.
It’s a very thin example that ties a lot of technologies together, so I’m sure there’s a helpful example for somebody in there.
