More Functional in Java with JavaSlang
9:00 AM MDT
Java 8 is pretty great, but mix in JavaSlang (now called Vavr) and get ready for some functional programming excitement.
JavaSlang is a project that decorates Java with immutable data structures, better Optionals, tuples, and more. Now with JavaSlang (Vavr) we can really bring in some more power to functional programming and Java. We will even discuss some new concepts like for comprehensions, Try, and Either!
Unveiling Kafka and Streaming
10:45 AM MDT
Kafka has captured mindshare in the data records streaming market, and in this presentation, we knock on its door and see what lies behind. What is the draw? What makes it an attractive addition? How does it compare to Message Queues and other message streaming services?
We will do a thorough introduction into what is Kafka. We will also discuss Consumers, Producers, Streams. Integration with ZooKeeper, and discuss the performance aspect of using Kafka.
Scala for Java Developers (1/2) (Laptops Optional)
1:30 PM MDT
Scala for Java Developers is a full live code and fast paced presentation and workshop (laptops optional), and this is all about the Scala language.
Scala is a wonderful functional/hybrid language. It will become one of the 5 languages that you will need to know to be a highly successful JVM developer in the very near future (others being Groovy, Clojure, Java 8, and JRuby). Scala, as opposed to some of the other languages, has quite a learning curve. This presentation was built for questions. We will start with some basics, how this presentation will flow and end will be up to you, the audience. Bring your intellect, curiosity, and your questions, and get ready for some Scala. Laptops optional so you can try stuff out on your machine and create questions of your own!
Scala for Java Developers (2/2) (Laptops Optional)
3:15 PM MDT
Scala for Java Developers is a full live code and fast-paced presentation and workshop (laptops optional), and this is all about the Scala language. This is Part 2, continuing where we left off from Part 1.

Testing in Scala
by Daniel Hinojosa
If you build your Scala application through Test-Driven Development, you’ll quickly see the advantages of testing before you write production code. This hands-on book shows you how to create tests with ScalaTest and the Specs2—two of the best testing frameworks available—and how to run your tests in the Simple Build Tool (SBT) designed specifically for Scala projects.
By building a sample digital jukebox application, you’ll discover how to isolate your tests from large subsystems and networks with mocking code, and how to use the ScalaCheck library for automated specification-based testing. If you’re familiar with Scala, Ruby, or Python, this book is for you.
- Get an overview of Test-Driven Development
- Start a simple project with SBT and create tests before you write code
- Dive into SBT’s basic commands, interactive mode, packaging, and history
- Use ScalaTest both in the command line and with SBT, and learn how to incorporate JUnit and TestNG
- Work with the Specs2 framework, including Specification styles, matchers DSLs, and Data Tables
- Understand mocking by using Java frameworks EasyMock and Mockito, and the Scala-only framework ScalaMock
- Automate testing by using ScalaCheck to generate fake data
