     Comparison of Scala & Go's concurrency constructs
            By Brent Smith and Leon Gibson
   What does Scala and Go offer your company for a scalable concurrent 
   solution?
   ● Scala
      ○ Immutable, persistent data structures
      ○ Functional Programming via First class functions, and Closures 
      ○ Scales up (concurrency) and out (remoting) with the Actor model
      ○ Software Transactional Memory
   ● Go
      ○ An expressive lightweight machine code driven language
      ○ Re-introduces the concept of "goroutines" and "Unix pipe-like" 
        channels
      ○ Simple abstractions that support concurrency via isolated mutability
      ○ High speed compilation
  Agenda
  ● Introduction to languages
   
  ● Discuss Scala concurrency features
   
  ● Discuss Go concurrency features
   
  ● Examples included in ScalaAndGo-
    CSCI5828_S12_BSMITH-LGIBSON.zip
   
  ● Comparison and Summary
    Scala
     ● General purpose language
     
     ● Built on top of the Java VM platform
     
     ● Mixes OO (imperative) and functional programming 
        styles
     
     ● Syntax is more concise and extensible than Java
     
     ● Average 2x reduction in code size vs. Java programs
     
     ● Scales up (concurrency) and out (remoting)
     
     ● Built-in support for Actors based concurrency model
