- 6. 2008 JavaOneSM Conference |java.sun.com/javaone | 6 Why We Chose Ruby? Primarily because of the Rails framework I resisted the hype of Rails for 1+ year but finally: • Took the advise of many intelligent pragmatic developers I know • Spent 4+ weeks developing with it • Conclusion? The hype is mostly true; productivity is very high Business Technical benefits seen so far Rapid prototyping/development because: • Language is concise and easy to read • Single-stack application framework (web MVC, ORM, unit testing…) • Almost no configuration required (No XML hell!) • Dynamically typed • Can be used for full OO applications or just procedural scripting • No compilation (prediction: in 5+ years, we will do away with compilation for 80% of the application development; just like we did away with linking) • More…
