The rise of lightweight technologies was largely due to developers' rebellion against the "heavyweight" of EJB 2.1 (and earlier). Lightweight frameworks aim to make developers more productive and the applicatio... (more)

Michael Yuan's Java Blog: "Is Ruby Replacing Java? – Not So Fast"

And Ruby has nifty language features we can only dream of in Java. So, Ruby must be replacing Java to become the "next" programming language just as Java "replaced" C++/COBOL and C++ "replaced" Fortran. We... (more)
