Personal Agility with the Pomodoro Technique

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.

Making Java Bearable with Guava (2013 Edition)

This presentation covers the Guava library developed by Google (http://code.google.com/p/guava-libraries/). Guava provides collection extensions to the Java Collection API and, along with this, a cornucopia of time-saving utilities that bring Java as close as possible to some of the more functional and dynamic language competitors like Scala, Ruby, and Clojure.

This presentation focuses on the following topics: how to make Predicates and Functions; how to use new collection constructs that make life easier, including MultiMap, BiMaps, and MultiSets; how to set up and use Guava preconditions; and how to create truly immutable collections, and more. All of this is done with Java. All code is stored on github. Laptops are optional but bring them over if you want to play along.

Testing In Scala

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.

It just so happens that testing code in Scala is a great way to learn Scala, but also really good at testing Java code. This presentation started a book on how to use some of the greatest tools that you can use to test. This presentation will cover ScalaTest, Specs2, ScalaMock and ScalaCheck all in a triggered execution environment using SBT. For those that do not wish to use SBT, we will cover other options as well. Using these tools you may never want to use those plain jane java testing frameworks ever again. While this presentation is not interactive, all demos will be available on github for those that want to "play" along with their laptops.

Scala: Demystifying The Funky Stuff

Scala is known for both its clarity in some cases, and its obscurity in others. Well, this presentation sticks with the obscurity. We will cover abstract types, the Predef, implicit conversions, creating infix types, singleton types, type variance, type bounds, type variance, partially applied functions vs. partial functions, type projections, and overcoming type erasure using Manifests.

This presentation is geared in at the programmer level and not at a scientific level, with no type theory or calculus. Basic knowledge of Scala is preferrable, though not required. Asking tough questions is mandatory.

Playing with the Play Framework

The presentation will cover an introduction on the framework by creating a basic web application in both Java and Scala to get you started.

The Play Framework is a lightweight and stateless web framework that is part of the TypeSafe stack, a stack which includes Akka middleware and the Scala programming language. The presentation will cover an introduction on the framework by creating a basic web application in both Java and Scala to get you started. The presentation will also cover javascript library integration and explain the philosophy behind the framework and give an honest analysis on the advantages and disadvantages of the framework. While this presentation is not interactive, all demos will be available on github for those that want to "play" along with their laptops.

I have seen the top Akka mountain, and it is good.

Presentation on Akka. A set various tools to write concurrent, fault-tolerant applications using immutable data, asyncronous message passing using local and remote actors, software transactional memory, and supervised systems.

Akka is a middleware, but it is not your 1990s middleware. Akka is a set of various tools to write concurrent, fault-tolerant applications using immutable data, asyncronous message passing using local and remote actors, software transactional memory, and supervised systems. Akka is also part of the Typesafe stack, a stack that include the Play web framework and the Scala programming language. This Akka presentation will cover both Scala and Java style usage of Akka and give the audience a 30k view of how it comes together. While this presentation is not interactive, all demos will be available on github for those that want to "play" along with their laptops.
