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.

Sam Stephenson, creator of the Prototype library, sat down and recorded himself remotely as we talked about what excited him about new Prototype versions, browsers, and the state of Ajax in general.

I use Aptana Jaxer, the Ajax Server, as a proxy for Twitter. This shows how you can write an application in pure JavaScript using 3rd party libraries such as Prototype on the server side.

I decided to give it a go, and used one of the 300 invite codes for myself. I added this to Wordpress, and was up and running in minutes.

I sat down with Zach Coelius, CEO of Triggit, who just released, in beta form, their WYSIWYG content insertion platform. It is good for your mum as she can add content without touching HTML. If is good for developers if we can plugin our own modules and use their platform.
