A nice modal window kit for Prototype.

"Amplify's goal is to simplify all forms of data handling by providing a unified API for various data sources." Looks like a write-once way to handle client side storage.

Some strategies for dealing with persistant URLs, Ajax state changes, and the back button.

Write an HTML5/JavaScript app and PhoneGap will turn it into a native app for various mobile devices including iPhone, Android, and Blackberry.

Still in Alpha, but this looks like a great way to speed-up mobile site development. The form elements demo is impressive.
