Random ramblings on Open Source, integration and other malarkey Don't get me wrong - I've written tons of Java over the last decade or so & think its been a great evolutionary step from C++ and Smalltalk (lots of other languages have helped too like JavaScript, Ruby, Groovy, Python etc). However I've long wanted a long term replacement to javac. I even created a language to scratch this itch. Java
