Brad will speak on "The History and Design of Objective C". Brad's interests are in digital rights management, reconceptualizing universities as interactive distributed learning communities, and software engineering. Most of his recent work is in XML, Java, Ruby, Python and Perl. Before those, he mainly used the language he invented early in his career, Objective-C[http://www.dekorte.com/Objective-C/].
