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).

Tuesday August 18, 2015: the Java Spark framework

Java Spark: Ruby developers get some of the coolest toys. They have these fun little frameworks that just do stuff in the most annoying way. Sinatra is one of those frameworks. Luckily for us Per Wendel decided that Java devs should get in on the fun, and so now we have the Java Spark framework, because Ruby shouldn’t get all the cool toys.

Bio:  Seth Lachner is very cool.  He’s is a long time member of OJUG.org.   His talks are always wonderful.

Tuesday: November 17, 2015 – Microservices and the great migration

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  :-)
Bio: Baruch Sadogursky (a.k.a @JBaruch) is the Developer Advocate of JFrog, the creators of Artifactory Binary Repository, the home of Bintray

Tuesday July 21, 2015: Java and Performance – Biggest Mistakes

Have you ever wondered why your e-Banking system is down yet again for maintenance or what problem it was that caused your check-out to take forever until it terminated with a weird error message?

Misconfigured O/R Mappers causing millions of SQL Queries and “leaking” DB connection leaks, excessive logging that consumes all Disk I/O, memory leaks that bring the JVM to crash every couple of hours or a forgotten XML configuration entry that causes millions of “Control-Flow Exceptions” that never make it to any log file. These are some of the problems that crashed large enterprise applications in the last 12 years (some even made it to national & international news). In this session we learn how to avoid these top problems by automatically looking at key performance and architectural metrics along your continuous deployment pipeline.

SPEAKER: Asad Ali

Asad Ali is an application performance enthusiast who has over 15 years of experience in Object oriented programming, Java, scripting languages and databases. For the last 7 years he has been working with enterprise clients with key focus on application performance. During his spare time, Asad likes to pursue his passion for photography.

Tuesday June 16, 2015: “A Brief History of Java” – an irreverent look at Java through the ages.

“A Brief History of Java” – an irreverent look at Java through the ages.

This somewhat tongue-in-cheek look at the development of developing with Java from 1.0 beta in late 1994 through today examines the popular tools and technique of the language and how they have evolved over the last 2 decades, from a guy who has been with Java since the beginning.
Bio:
Kent Smotherman taught his first lecture class for computer programming in 1980 at Kansas State University, at the age of 19. Since then, he has learned and programmed in over 2 dozen programming languages, including Fortran (that very first class), LISP, various assembly languages, C++, and Java, on platforms ranging from IBM Mainframes down to Android devices. Java is his favorite, however. “Java brings the power of programming to almost any platform on the planet, and the significance of that to the academic world of computer science as well as the practical world of Information Technology cannot be understated.” Kent has worked for most of Omaha’s biggest companies like Mutual of Omaha, First Data, and CSG. In his roles at these companies, he has traveled all over the country and the world as a specialist in programming, technology, and systems software debugging. But what really excites him is the web. “The explosion of the world wide web is an historic epoch in modern civilization. Not just in what everyone can do with it, but the fact that web development itself is so accessible. Combine that with the flexibility offered by Java, and you have an environment where the sky is the limit.”
Kent has taught web development technologies for government agencies such as the Florida Department of Education and Strategic Air Command, as well as free programs for kids that just wanted to learn how to make a web site. “It doesn’t matter what you know now, it only matters what you are capable of learning. And with the right attitude, a little hard work, and a good instructor – anyone can learn web development.”
Kent currently works during the day as the mild-mannered senior web application architect at NCR, and superhero Java web instructor at night for Interface Web School.

Tuesday March 17, 2015 — Groovy kata

At this meeting, we’ll work through a solution to the Bank OCR kata, http://codingdojo.org/cgi-bin/index.pl/index.pl?KataBankOCR, using Groovy and functional programming techniques. As we work through this programming kata using Groovy, we’ll use pure functions that are small and easy to test. The code will use recursion plus Groovy methods that support functional programming such as take, drop, first, tail, find, findAll, collect, collectMany, and transpose.

Speaker: Scott Hickey is Chief Technologist (Object Partners, Inc.) at Mutual of Omaha.   He is a wonderful speaker and very nice guy.

Lightning Talks and CodeEnvy.com January 20, 2015

two part meeting:

Part One: Local Lightning talks from Seth Lachner (jClouds), Matt Payne (SonarQube etc).

Part Two: Remote via WebEx/GotoMeeting/Google-hangout

Tyler Jewel from CodEnvy.com writes:

Title: Contribute to Any Project in Seconds with a Cloud IDE

The Java community is filled with terrific solutions for enabling development of apps.  Every Java developer has their choice of tools and the openness of the platform makes it accessible to anyone and extensible by everyone.But why then, is 99% of all development still done locally?  While sales, marketing, customer service, support, finance, and infrastructure has steadily moved to the cloud over the past decade, Java development remains rooted on the desktop.  Will it always be this way?

Coder utopia: where environments are instantly accessible from any computer; where any number of private machines with root access can be provisioned at will; and developers build, test and debug with infinite, non-thrashing resources.

In this session we will introduce Codenvy, a no-blocking, no thrashing cloud IDE combined with automation that provisions developer workspace replicas that are simply shareable and secure to manage.

Session Length: 45 Mins

Session Agenda

1) Why Cloud Development

2) Types of Cloud IDEs

3) Demo of Codenvy

** Remote workspace & project configuration

** CLI & Browser access

** Temporary, on-demand environments

** Shared development: editor, syntax analysis, collaborative coding

** Cloud build, dependency management, unit test (maven / ant / groovy)

** Cloud debug (runner, multi-process container, shell access)

** Project persistence (storage, image mgmt, privacy)

** Project creation (resource management, cloud bindings)

** Datasource management (cloud vs. local resources)

** Analytics (user dashboard, derived metrics, session tracking)

** Cloning (creating re-usable environments, embeddable, customizable)

** Plug-ins (extending browser and server-side cloud functionality)

** APIs (accounts, workspaces, projects, runners, builders, etc.)

** Offline and On-Premises Access (running proprietary clouds)

 

i) Lift, grails, wicket, tapestry, GWT, JSF, Thymelaf, xtream, Vaadin, Shale, velocity, Play, Struts

ii) JBoss, GlassFish, WebSphere, Oracle WebLogic, Jetty, Resin, Tomcat, Virgo, Geronimo, TomEE

iii) JRuby, Groovy, Maximize, Kotlin, Jython, Scala, Ceylon, Clojure, Rhino.

Tuesday October 21, 2014 – Buzzworthy Java with Spring Boot and JHipster

Learn about Spring Boot, a new opinionated convention-over-configuration RESTful framework that makes your life easier.

  • Get up and running in minutes

  • Writing web apps without or with a WAR?!?!

  • Deploy without or with an app server?!?!

Yes is the answer!

“Spring Boot makes it easy to create Spring-powered, production-grade applications and services with absolute minimum fuss. It takes an opinionated view of the Spring platform so that new and existing users can quickly get to the bits they need.

You can use Spring Boot to create stand-alone Java applications that can be started using java -jar or more traditional WAR deployments.” — https://github.com/spring-projects/spring-boot

Then take it to the next level with JHipster, a buzz-worthy opinionated full stack generator that pulls together AngularJS + Spring Boot with many tools:

  • build (Gradle + Grunt)

  • front end (Twitter Bootstrap, Thymeleaf, WebSockets)

  • back end (Spring-Loaded hot reload, monitoring metrics, Hazelcast, HikariCP)

“JHipster is a Yeoman generator, used to create a Maven + Spring + AngularJS project, with full hot reload of Java and JavaScript code.” — http://jhipster.github.io/

Speaker: Jeff Sheets is a Principal Consultant with Object Partners working on Grails and Java projects.
