Java

Dr. Stefan Schmidt (@schmidtstefan) has been working with SpringSource for almost two years and has been a key developer on the Spring Roo team in Sydney, Australia. Spring Roo is a project designed to assist you in creating fully working Java applications based on Spring technologies. Stefan will be speaking about Spring Roo at the Strange Loop conference.

Charles Oliver Nutter (@headius) is well-known for his work on JRuby, the JVM-based implementation of Ruby. During his time at Sun, he has also been an enthusiastic early adopter of the work done by the JVM team for JSR 292 and invokedynamic to allow more flexible method invocation, a key feature needed by dynamic languages.
