Lots of new projects for Ruby on Rails and/or just Ruby:

As I mentioned earlier, I launched ActiveShipping which can be used either with Rails or by itself.

If you ever wanted an easy way to write forms for which portions appear/disappear based on the results of a drop-down box, I have a Rails plugin called Applicability:

If you ever wanted an easy way to do client-side tabbed panels, I now introduct RailsTabbedPanel:

Neither of these require you to manage Javascript yourself -- it handles all of the Javascript generation for you in a clean manner. You can even have multiple tabbed panels and multiple applicability containers together, and nested.
