Dion and Ben are joining forces and have the opportunity to start a new group at Mozilla, focused on developer tools on the Open Web.

In this announcement we chat about our excitement, what we are looking to do, and how we can't wait to approach this in a Mozilla like way: with openess, transparency, and community.

If we started annotating the events in our Web applications, then we could allow users and scripts to come in and add key bindings to tie into those events. This is a simple experiment of that in practice.

In this video I am showing a simple example of custom events, using Prototype (although I could use other libraries), and how I tend to think of the events that my application has, and I strap on behaviour via the fire() and observe() methods.

I recently ported my Gears-front end Addressbook History pattern sample to use App Engine as the backend data store. This short video walks through the application and the code, to give you a quick feel for App Engine development.

The form history pattern gives you a way to show history to your users as an even better UNDO. This video walks you through an example with code.
