comment Error checking in actor-based paradigm
Moreover, one has to send back the failure explicitly, as the docs say: "To complete the future with an exception you need send a Failure message to the sender. This is not done automatically when an actor throws an exception while processing a message."

comment Error checking in actor-based paradigm
Yes, this is what I added parenthetically "One can have a return value using Futures, but it certainly not customary to ask for futures on every message.". But this requires generating a Future for every call, which basically means doing away with ! and getting a fixed overhead. I do not think this is the customary way to build an actor-based application.

comment Is Groovy going away?
I beg to disagree about Scala being academic. It is actually very productive and helpful, and currently in use in many financial institutions, on Linkedin, Twitter and so on. I actually tried both Scala and Groovy here where I work, and I would never choose Groovy for projects over a mild threshold of complexity.

comment Is Neo4j graph database sufficient to itself for all query types?
Given that the only operations in SQL are essentially join and filters, and that filters are trivial in Neo4j, while joins can be simulated by following a relation with a given name, I would say yes. I am not sure that it would be a very efficient way to query, though.

comment How will the new development of Java influence its interoperability with languages like Scala and Clojure?
@maple_shaft Yes, a Scala String is a Java String. As with any other class, the mechanism of implicits can be used to add new methods to the existing class at compile time, but these are translated by the compiler in calls to methohds on a wrapper class.

comment Are immutable/stateless singletons bad?
It is not bad, to the point that Scala has a keyword for it (object) and that these objects are the basis of Scala's module system

Yes, you definitely should learn the language you are using from simple examples, before trying to learn a complex platform.
