SOLID Code 5/17/16

“Is your code SOLID? How do you know if your code is SOLID? One way to solidify your code is by following the SOLID design principles and other principles of good design. At this meetup, Jessica Codr will lead us through these principles by showing examples of code that could be improved and getting your feedback on how to improve that code. Along the way, we will identify SOLID and other principles that we can apply to our everyday coding lives.

After we’ve seen these examples we will, as time allows, work together on refactoring a code base to better adhere to principles of good design, with the end goal of making the code more maintainable and extendable.

This will be an interactive session, so come willing to share your thoughts as we all learn and grow together!”

Bio: Jessica Codr is very cool. She is a long time member of OJUG.org (and one of the organizers). Her talks are always wonderful.

Intro To Groovy 6/21/16

Intro To Groovy

We’ll run through a whirl-wind tour of the Groovy language, pointing out a few things that differentiate Groovy from Java.  Syntax and code style will be covered and we’ll introduce closures and Traits. There are real labs that we can cover to get you more familiar with the basic concepts!

Ratpack.io Tuesday April 19, 2016

From ratpack.io

Ratpack is a set of Java libraries that facilitate fast, efficient, evolvable and well tested HTTP applications. It is built on the highly performant and efficient Netty event-driven networking engine.

Ratpack is purely a runtime. There is no installable package and no coupled build tooling (e.g. Rails, Play, Grails). To build Ratpack applications, you can use any JVM build tool. The Ratpack project provides specific support for Gradle through plugins, but any could be used.

Ratpack is published as a set of library JARs. The ratpack-core library is the only strictly required library. Others such asratpack-groovy, ratpack-guice, ratpack-jackson, ratpack-test etc. are optional.

This talk is constructed to describe the conciseness of ratpack applications while discussing how this solution breaks away from servlet based solutions. It will be a tutorial that will allow the audience to play with functioning aspects of the different ways you may want to configure your ratpack applications.

DropWizard

 

DropWizard
This talk will cover the basics of DropWizard. The goal is to describe what it is, what it does, and some of it’s capabilities. We’ll go through a working example of a DropWizard Service. Finally, I’d like to share with you how we are using it and how we got into it.

Java 8! (12/15/15)

Dive into the new Lambda Expressions in Java 8, including method references, the new functional interfaces provided by the JDK, the Stream & CompletionStage APIs, and possibly a few other new features like default methods in interfaces and the compiler’s improved type inference.

Microservices and the great migration (Nov 17th)

The Great Migration

Micro-services have been getting a lot of attention in the past year, but is it really a viable solution or just a passing fad?

In this presentation we’ll look deep into Bintray.com’s service architecture and talk about how and why we found ourselves naturally migrating from a central web application to a flock of micro-services.

Of course maybe a groovy puzzle or two if we have time :-)

September 15 – IntelliJ vs Eclipse Showdown

Think of your classic rivalries:

  • Sega versus Nintendo
  • Hulk Hogan versus Andre the Giant
  • PC versus Mac
  • Tabs versus Spaces

The most contentious of all: which Java IDE is the greatest? We’ll be settling this score, once and for all!

Join us this month for an IntelliJ vs Eclipse Showdown – we have champions on each side (David Zemon for IntelliJ, Paul Heaberlin for Eclipse) ready to showcase their editor’s features, trash talk their opponent, and definitively prove which 200 megabyte zip you should be downloading the next morning.

Bios:

David Zemon is an technology evangelist raised by two computer engineering graduates. His free time is entirely consumed by programming the Parallax Propeller microcontroller (with JetBrains CLion).

Paul Heaberlin has been working with Java as a backend dev for over a decade and still enjoys it!  He’s presented at OJUG a few times, and if given the chance will likely talk your ear off on any topic he knows about (and probably a few he doesn’t).
