This document summarizes a presentation about developing desktop applications using Adobe Integrated Runtime (AIR) with Aptana Studio. The presentation demonstrates building a Twitter client application called YafTc that retrieves and sends tweets using AIR features like accessing the filesystem and network. It discusses installing Aptana Studio and the AIR SDK, creating an AIR application, adding a user interface with controls, retrieving external data via AJAX, and saving data to the local filesystem. The goal is to show how developers can create rich desktop applications using the web development skills and technologies they already know like HTML, JavaScript and jQuery.
