Yahoo! released the Yahoo User Interface Library (YUI) as a free, open-source JavaScript and CSS library eighteen months ago along with a commitment to the developer community: We'll share with you our best frontend tools, engage with you about how they're built and why, and we'll document them fully. In that short time, YUI has become one of the best-regarded frontend libraries and has been adopted by individuals on their blogs, startups who are going all-in with YUI as the foundation of their frontend architecture, and Fortune 500 companies using YUI as a trusted, tested, long-view toolkit for creating great user-experiences on the Web.

In this session, we'll look closely at the state of YUI today:

1. How is YUI organized around the challenges of CSS and JavaScript as they manifest in rich web applications?

2. What problems does YUI solve?

3. What does YUI offer as a foundation for your own development?

4. How can you deploy YUI to best effect with respect to accessibility, performance, and scalability?

Throughout, we'll look at specific examples with code and hear from the developers who are working on the YUI codebase. You'll leave with a deep understanding of what YUI is, what its development philosophies are, and whether it's a good choice for your own projects.

Speaker Bio: Eric Miraglia, engineering manager of the YUI Team at Yahoo!,has been authoring social Web applications since 1995, when he began developing interactive writing spaces for universities; his Speakeasy Studio & Cafe was used by more than 100 universities between 1997 and 2004.
