MAIN TOPIC ABSTRACT
NetKernel

NetKernel is a software platform that combines the idea of simple abstractions and sets of tools (awk, grep, sed, etc.) with the flexibility of the World Wide Web. The question that drove the research and development behind NetKernel is simple:

Can the flexibility of the Web be provided inside software?

This presentation will show how NetKernel 4 answers this question
with a resounding "yes".

NetKernel 4 is a fully refined REST computing abstraction that runs on an operating-system caliber microkernel. On top are a wide range of libraries supporting languages such as Java, Scala, Python, Ruby, Groovy, JavaScript, XSLT, XQuery, etc.

BASIC CONCEPTS ABSTRACT
Whither Micro Java?

The cell-phone version of the Java Virtual Machine is estimated by Microsoft to be available on two billion phones presently in use. It may therefore be surprising that this mature technology is widely considered to be the "least cool" application delivery platform of the Iphone Age.

What Sun created ten years ago was a specification without a corresponding implementation of the sort that made Java free and popular on desktop platforms, and the result has been a programmer's nightmare of incompatible and buggy JVMs on an incredible variety of phones.

Now phone makers and service providers are desperate for new features, distribution strategies, and buzz to compete with Apple, and even open-source is part of the push to revive this technology.

MAIN TOPIC ABSTRACT
Concurrency on the JVM Using Scala

Multithreading on multi-core processors and multi-processors bring a new challenge. Unlike multi tasked systems, your applications when deployed on these processors get a greater availability of computing power and resources. However, the level of abstraction for creating multithreaded applications is too low in Java. You are confronted with possibilities of data contention and thread deadlocks. One of the key strengths of Scala is its actor based concurrency model with immutable state. In this presentation we will exclusively focus on the concurrency API and facilities of Scala. We will develop a very practical and realistic application that illustrates the elegance, simplicity, and strength of Scala Concurrency.

BASIC CONCEPTS ABSTRACT
Scala Paradigms

Whenever a language begins to gain popularity there is a need to present introductory material. But after a awhile the need shifts to understanding the strengths of a language.

So in this presentation I am going to present a snapshot of Scala's unique features and paradigms. At start of the talk you will get to know Scala syntax, closures and functional programming. From this point we will study the improvements Scala makes to OO with strong typing, traits and mixins and how these improvements provide intrinsic support for new paradigms. Finally we will discuss how Scala's capabilities are finding there way into the real world.

MAIN TOPIC ABSTRACT
Database Refactoring with Liquibase

You're good at building applications, and you impress DBAs with your relational database designs. Your schemas as flexible, expressive, and performant—but not even you get it right on launch day. If you don't have a way to manage changes to your database, it will soon become mummified, cursing your application with declining performance and ugly hacks for the rest of its life.

Or maybe you've been saddled with a legacy database that looks like it was designed by the High School DBA Club on the last day of the semester, then filled with ten years of critical business data. You can't throw it away, but you can't build the next-gen application on it either. Learn how change control and the right set of practices can help you build an application you love from a database you'd just as soon do without.

MAIN SPEAKER BIOGRAPHY
Tim Berglund

Tim Berglund runs a software consulting firm called the August Technology Group, which provides training and development services to customers building web applications on the JVM. With his keen sense of timing, Tim spent his early career writing firmware, then switched to the Internet just as soon as the dotcom boom was coming to an end. He loves open-source software and the rapidly diversifying world of the Java platform. He has been writing software since he was a boy, but only started brewing his own beer a few years ago. He lives in Littleton with his wife and three children who, despite being the homeschooled children of a programmer father, don't write as much code as you might think.

BASIC CONCEPTS ABSTRACT
Intro to Python

Python, named after Monty Python's Flying Circus, is a dynamic, strongly-typed, bytecode compiled, cross-platform, programming language. Python has extremely readable syntax and is used in a multitude of problem domains, from numerical computing to network games. As well as being easy to read, python is easy to write. With python, you develop more with less effort. It is a language that allows rapid development of maintainable code.

This talk will cover The Zen of Python, python syntax, the powerful built in object system and built in datatypes. After the basics, we'll cover some of the awesome features of python, such as decorators, doctests, generators, list comprehensions, tuple unpacking, the 'with' statement, keyword arguments and the interactive interpreter.

MAIN TOPIC ABSTRACT
AMQP and QPID

Enterprise Messaging systems let programs communicate by exchanging messages. Enterprise messaging systems require guaranteed delivery, high throughput, low latency, and other features like security. Until recently, there was no open standard for Enterprise Messaging systems, so programmers either wrote their own, or used expensive proprietary systems. Even standards like Java's JMS specify no standard on-the-wire-protocol and can lock users into proprietary implementations.

Advanced Message Queuing Protocol or AMQP is the first open standard for Enterprise Messaging. It is designed to support messaging for just about any distributed or business application. Routing can be configured flexibly, easily supporting common messaging paradigms like point-to-point, fanout, publish-subscribe, and request-response.

Apache Qpid implements the latest AMQP specification, providing transaction management, queuing, distribution, security, management, clustering, federation and heterogeneous multi-platform support and a lot more. And Apache Qpid is extremely fast. Apache Qpidamins to be 100% AMQP compliant.

In this discussion we will look at the AMQP standard and how it's architecture provides both flexibility and high performance. We will then take a look at some code examples using Apache Qpid in several computer langauges. As we wrap up the discussion we will take a lookat some of the use cases in various industries and other open source projects that AMQP and Apache Qpid are being used today.

BASIC CONCEPTS ABSTRACT
Intro to JRuby

There was a time not too far ago where adopting Ruby meant having to abandon Java. JRuby allows you to adopt a powerful and expressive language and still have access to the abundance of libraries and frameworks available on the Java Platform.

This talk will provide an introduction to JRuby and how to combine Java and Ruby code to write powerful and flexible applications.

MAIN TOPIC ABSTRACT
Intro to Rails

During the previous meetup, we learned about the Ruby language. In this talk, we are going to take Ruby to the next level and learn about the Ruby on Rails. Ruby on Rails is a web framework built on top of Ruby that focuses on convention over configuration to get things done quickly. It was originally developed by David Heinemeier Hansson at 37signals for the Basecamp application. Eventually, the framework was extracted from Basecamp, open sourced, and is now known as Ruby on Rails.

You will learn how to install Rails; build models, views, and controllers; connect to a local database, and quickly get an app up and running. Code will also be provided so that you can play with Rails on your own.

BASIC CONCEPTS ABSTRACT
Getting started with Android development

Many of us have small powerful computers, disguised as cell phones, that we carry with us all the time. These devices have been opened up, to a varying degree, to allow us to run our own applications creating whole new opportunities that did not exist previously. In this talk we will examine the similarities and differences of two interesting and important systems: The iPhone and Android. We will also talk about how to get started programming and developing for the Android.

BASIC CONCEPTS SPEAKER BIOGRAPHY
