It does show how "Scala is powerful", exactly in the meaning that Mario gave a few days ago. Complexity is not easily to demonstrate in a blog post, because I interpret it as the required bag of notions needed by a developer (who's neither Dick nor Mario) to solve a problem in a smart way.
In other words, let's give: 1. a problem 2. a solution in Java made of 100 LoC and a cost of maintenance that I set to "1" 3. a solution in Scala made of 10 LoC and a cost of maintenance that I set to "0.1" This is the typical Scala ( / whatever) evangelism example. This demonstrates that Scala is more powerful with respect to two software qualities (LoC and cost of maintenance). Still, if - starting from zero knowledge of both languages - I need 4 months of learning / trying to get to the Scala solution and 4 weeks to get to the Java solution, I'm still saying that Java is simpler. Note that - also to bring in the other thread by Mario - in function of the numeric relative figures of properties (that of course in my example I put at some example random values), the Scala solution might prove an advantage in the long run (because when I'll eventually get proficient in Scala I'll be able to write better solutions) or not (because the time will be longer that a given milestone, or because when I'll get to that Scala proficiency I'll move to a new, better paid job, leaving my employer with an open problem - he'll have to spend more, or get back to another new Java developer who's not able to maintain the current Scala code. I hope that this example clarifies where the Scala adoption problems lie in the real world and can't be solved by a blog post. - -- Fabrizio Giudici - Java Architect, Project Manager Tidalwave s.a.s. - "We make Java work.
