Joda Time and a Brief History of the World
8:30 PM MDT
JodaTime is Java Date/Time and Calendering done right. There are many problems with the original Date/Time API that came prepackaged in the early Java days. There are even
One of the obvious issues is that Calendar is mutable and can unintentionally be changed. Another issue is that constructing Calendars in Java involves setting certain fields at certain times during coding, but not always getting the expected result. Joda Time repairs those issues and offers a robust and immutable date, time, and duration API.
In Joda Time and a Brief History of the World, I provide a quick rundown of calendaring throughout the centuries, describe UTC, compare UTC to GMT, discuss how time is calculated, and then dive into Joda Time in every popular JVM language. The end result provides the audience with compelling proof that Joda Time should always be their Date Time API of choice.
Personal Agility with the Pomodoro Technique
1:30 PM MDT
Time is very precious and is often threatened by phone calls, emails, co-workers, bosses, and most of all, yourself. The Pomodoro Technique reigns in unfocused time and gives your work the urgency and the attention it needs, and it's done with a kitchen timer.
In this presentation we discuss how to set up, estimate time, log time, deal with interruptions, and integrate with Agile as a team. We discuss timer software and even some of the great health benefits of the Pomodoro Technique.
Testing In Scala
1:30 PM MDT
Most introductory programming books include a chapter on testing, seemingly as an afterthought. For the test-driven developer, that's a little too late. Some programmers approach a new programming language with a few test-cases to understand a concept. Others thrive under fire and want to hit the ground running in a new programming language by creating an application. Regardless of your profile, this presentation will help you get started with a Scala testing environment so you can concentrate on the finer points of the language.
This presentation will cover SBT (Scala Build Tool), Specs, ScalaTest, and Automatic Test Generation with ScalaCheck.

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
