I pushed out a couple of plugins over the weekend for dealing with failure in Pakyow apps. Here are some links:
These two gems are the first plugins for Pakyow. By plugin, I mean that a developer doesn't have to do anything but update their Gemfile to get the functionality in their app. Things just work out of the box, and the developer still has the ability to override functionality at will (e.g. use their own 404.html page). I plan to write a more formal guide on Pakyow's plugin architecture as I think this opens the door to lots of cool things.
If you have any questions or comments I'd love to hear them.
Take care,
