Java, Python, and Jython
Today, James Gosling announced that Ted Leung (Python) and Frank Wierzbicki (Jython) will become Sun employees this month.
Ted is an author, Apache Software Foundation (ASF) member, and long-time Python developer at the Open Source Applications Foundation (OSAF). Frank Wierzbicki is lead implementer of the Jython project (Python on the Java VM). They'll be working full-time on Jython, paying attention to developer tools in particular.
Sun believes the Java platform is bigger than just the Java language and supports giving developers a choice. In fact, Sun is planning to support multiple languages on the Java platform (i.e. Groovy, Ruby, and Java FX) and to provide more interoperability between Java and other languages.
Ted and Frank join other technologists, such as Ian Murdock, Charles Nutter, Thomas Enebo, and Nick Kew who have recently joined Sun to pursue open source project development and community activities.
