SunJUG September Meeting - Introduction to Apache Mesos

September's topic will be "Introduction to Apache Mesos" presented by Chris Schaefer

Meeting Overview:

Over the history of data center computing, machines and later virtual machines have been statically allocated for various needs. These machines and instances take time to provision, allocate and generally go under utilized. Apache Mesos is a cluster management tool that takes the computing power in your data center (or cloud provider) and represents it as one large computer by providing access to resources (RAM, CPU, etc) instead. This removes the need for static allocations of machines/VM's, provides developers easier access to computing power and potential cost savings by sharing the load across all machines in the cluster where resources are available. In this session we will cover what Mesos aims to solve and how, along with how to use it to run your applications in a scalable and fault tolerant way.

This event will take place on September 24th, 2014.

Please RSVP for this event!

SunJUG May Meeting - The Bilingual Developer - iOS and Android

May's topic will be "The Bilingual Developer - iOS and Android" presented by Tim Crowley

Meeting Overview:

The mobile market has seen an explosion in development and innovation over the past several years. And although there were several initial players, the market has consolidated around two key platforms - iOS and Android.

Although these operating systems have many similarities, the development environments are significantly different. In this introductory presentation, Tim will compare and contrast the platforms, and provide guidance on how to minimize the amount of rework that's required when developing for them.

Speaker Bio

Tim Crowley has been developing software for most of his life, although he's been doing it professionally for 20 years. Tim primarily works on Java applications, but has developed a passion for mobile apps, and is currently published on both the iOS and Android app stores. When not developing software, Tim spends time with his kids fishing and (poorly) skateboarding.

This event will take place on Wednesday May 28th, 2014.

SunJUG February Meeting - Computer Vision using Java

Please join us for our February meeting, presented by Steve Goldsmith on "Computer Vision using Java".


Computer vision is a field that includes methods for acquiring, processing, analyzing, and understanding images and, in general, high-dimensional data from the real world in order to produce numerical or symbolic information, e.g., in the forms of decisions. I'll break down the installation of OpenCV on Ubuntu (although there's support for Windows, Mac, iOS and Android) on x86, x86_64 and ARM based devices. I built an automated script that does all the heavy lifting of installing and compiling FFMPEG (x264, fdk-aac, libvpx, libopus) and OpenCV from source. This will get you the latest and greatest OpenCV with Java and Python bindings. Then I'll move into Java examples for motion and people detection. Finally I'll cover a new project I'm working on called Java Video Processor that uses a plugin based architecture and lose coupling to provide a complete Computer Vision solution. I'll try to stay away from the rocket science of computer vision and focus how you can get started without a PhD.

Presenter Bio:

Senior level professional with extensive experience in architecture, development, testing, continuous build processes, declarative and meta programming. I have worked for insurance, real estate, finance and technology companies. I'm currently focusing on large scale middleware built with open standards. I have led/managed development teams as well as being in the trenches. I enjoy the total life cycle challenge of R&D, networking, deploying servers, database design, developing code and post production support. I have over 34 years of experience in the Computer Science field with 27 years of that being an IT professional.

SunJUG January meeting - Modern Messaging with RabbitMQ

January's topic will be "Modern Messaging with RabbitMQ" presented by Vladimir Vivien, Senior Consultant of Pivotal, Inc.

Meeting overview:

If you have built message-based software systems in Java over the years, your choices where most likely limited to "JMS" broker. While JMS is the workhorse in numerous enterprises, it has several shortcomings that make it less than ideal for the emerging polyglot and agile technological ecosystems. This presentation is to provide a high-level introductory view of modern messaging using RabbitMQ, an open source messaging platform. We will look at RabbitMQ, its underlying protocol AMQP, and how to build scalable messaging infrastructure using Java + RabbitMQ.


  • Why Modernize Messaging?
  • What is RabbitMQ + AMQP
  • Concepts in AMQP
  • Messaging with Java + RabbitMQ
  • Scalable Enterprise Messaging with RabbitMQ
  • The event will take place on Monday January 27th, 2014:

Looks like things are a go and we are having our first meeting before the new year starts as a "brew night" where we can just get together and talk about tech stuff then resume meetings Jan. 2014.

    While the main site will still be active, I will be using as well which provides the ability to RSVP for events and so on. With that said, please join me in starting the SunJUG up again!.

    If you plan on attending the brew night please RSVP, otherwise feel free to join the SunJUG meetup group itself for future updates.
