A new Chat Resource Center has been launched, offering overviews, tutorials, and design patterns for creating mobile and web chat applications. Developers can quickly start mobile app development using jQuery Mobile and PubNub, exemplified by a mobile chat app built in under an hour with only 125 lines of HTML, CSS, and JavaScript code. The app utilizes basic jQuery functions for UI interaction and PubNub's publish and subscribe functions for cross-device communication, with all necessary code available on GitHub. A PubNub account is required to obtain unique keys from the PubNub Developer Portal to enable these functionalities.
