  1. Running An Apache Spark Application on Amazon Elastic MapReduce

    This is a series of guided screenshots on how to run an AWS EMR Spark application. Last time we wrote a spark count application that found the list of channels with more than 24 hours of programming. We will run that same application this time on EMR instead of the…

  2. Getting Unique Combinations Of Products with Apache Spark

    This Apache Spark snippet looks at users who have rated a series of products and pulls out the unique combinations of the products rated by each user to start building a recommendation system. To get there though we will go through a multi-part MapReduce algorithm. Some Terminology: (k,v) denotes…

  3. Running A Count With MapReduce in Apache Spark

    Apache Spark Snippet - Counts This is the first in a series of snippets on Apache Spark programs. In a previous post I ran a machine learning algorithm through Spark and will be following a similar setup using the Hortonworks Sandbox. In the future I'll do some snippets on AWS'…

  4. RabbitMQ, FTP Microservice and Docker

    I decided to make a quick video on a microservice written in Scala and Akka working with a RabbitMQ message broker and a Pure FTPD service both running inside Docker containers. The video will demonstrate: An Intro to RabbitMQ and its web interface. Some fallback mechanisms if RabbitMQ goes down…

  5. Solving A 2D Maze Game Using a Genetic Algorithm and A* Search - Part 2

    Part 2 focuses on solving the simple maze in this earlier post. Just as a recap though the maze looks like this: # = Wall P = Player F = Finish = Floor Tile # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # P # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # F # # # # # # # # # # # # # # # # Solving it might not be the right word as a genetic algorithm is more of an optimization algorithm. Optimization…

  6. Solving A 2D Maze Game Using a Genetic Algorithm and A* Search - Part 1

    There's a lot of material out there on genetic algorithms and A * Search. I decided to just make a little 2D maze and approach the problem two different ways to better understand both algorithms without introducing too much complexity, get familiar with Scala and of course make it a bit…
