Colloquium - Najork

Oblets and Collaborative Active Textbooks
Digital Systems Research Center

Many Web browsers now offer some form of active objects, written in a variety of languages, and the number and types of active objects are growing daily in interesting and innovative ways. This talk describes our work on Oblets, active objects that are distributed over multiple machines. Oblets are written in Obliq, an object-oriented scripting language for distributed computation. The high-level support provided by Oblets makes it easy to write collaborative and distributed applications.

Oblets form the basis of CAT, a Web-based algorithm animation system. CAT augments the expressive power of Web pages for publishing passive multimedia information with a full-fledged interactive algorithm animation system. It improves on previous Web-based algorithm animations by providing a framework that makes it easy to construct new animations, including those that involve multiple views. Because views of the same running algorithm may reside on different machines, CAT is particularly well-suited for electronic classrooms.

Refreshments will be served immediately before the talk at 3:30pm.
Hosted by Dirk Grunwald.
