Implementing a Simple State Machine with Akka

Problem

Prof. Charles Pinter's A Book of Abstract Algebra presents the following exercise:

Ch 6 (Functions) part H, problem 4
Given a stream of 1's and 0's, draw the state machine diagram if the stream ends with 111

I came up with the following diagram:

{-# LANGUAGE GeneralizedNewtypeDeriving #-}
module SliderPuzzle where

import Prelude hiding (Either(..))
import Data.Vector (Vector, (//), (!?))
import qualified Data.Vector as Vec
import Control.Arrow (second, (***))
import Control.Monad.State.Strict
import Data.Set (Set)
import qualified Data.Set as Set

	end

Getting Started in Scala

This is my attempt to give Scala newcomers a quick-and-easy rundown to the prerequisite steps they need to a) try Scala, and b) get a standard project up and running on their machine. I'm not going to talk about the language at all; there are plenty of better resources a google search away. This is just focused on the prerequisite tooling and machine setup. I will not be assuming you have any background in JVM languages. So if you're coming from Python, Ruby, JavaScript, Haskell, or anywhere…  I hope to present the information you need without assuming anything.

Disclaimer It has been over a decade since I was new to Scala, and when I was new to Scala, I was coming from a Java and Ruby background. This has probably caused me to unknowingly make some assumptions. Please feel free to call me out in comments/tweets!

One assumption I'm knowingly making is that you're on a Unix-like platform. Sorry, Windows users.

Recently I happen to see so many posts regarding this " Google XSS Challenge " and i was fortunate enough to complete them..
These are the solutions for the challenges ;)

What is the appeal of dynamically-typed languages?

Kris Nuttycombe asks:

I genuinely wish I understood the appeal of unityped languages better. Can someone who really knows both well-typed and unityped explain?

I think the terms well-typed and unityped are a bit of question-begging here (you might as well say good-typed versus bad-typed), so instead I will say statically-typed and dynamically-typed.

I'm going to approach this article using Scala to stand-in for static typing and Python for dynamic typing. I feel like I am credibly proficient both languages: I don't currently write a lot of Python, but I still have affection for the language, and have probably written hundreds of thousands of lines of Python code over the years.
