#Code is Data, So Own Your Code!

Other day a co-worker showed me this piece of code and asked me how we could re-write it in a more Scala way.

//generate id based on rule characteristics
if(priceStatusRule && hierarchyRule && markdownRule && lastReceivedDateRule){
  priorityId = 1
} else if(hierarchyRule && markdownRule && lastReceivedDateRule && !priceStatusRule){
  priorityId = 2

#Questions for Martin Odersky @ Saks ##Grouped by areas

1. Future of JVM and Scala

   • Where do you see the future of JVM languages going? Scala, Java 8, Closure.
   • Can you speak about dotty and how older scala versions will be impacted?
   • Future evolution of the Scala Stack: should we expect more new features in the core of the language (e.g. Macros in * Scala 2.10) or more on the "enterprise" stack (e.g. Akka, Play, ...) ?
   • Java 8 lamba expressions: is Scala going to include that as part of its syntax or is it going to keep the same functional syntax leveraging the implementation on lambda expressions?

2. Functional Programming

   • It's been 35 years since John Backus's Turing award speech about FP. What are your thoughts about where FP is today?

#Coding Exercise ##Abstract

The exercise is broken in 3 parts, as described below. When you are done, follow these steps to delivery your answers.

• Create a new repository in Github, and upload your entire project, with the code you wrote, into Github
• Send us the URL to the repository
• Note, we should be able to clone your repo and compile all code in the project you created.

#How to handle caching in a functional way

scala> case class StlCache(pcode : String, stl_pcode : List[String], ttl : Int)
defined class StlCache

scala> val lamer = StlCache("01", List("02", "03"), 100)
lamer: StlCache = StlCache(01,List(02, 03),100)

scala> val lancome = StlCache("04", List("05", "06"), 500)
lancome: StlCache = StlCache(04,List(05, 06),500)
