6:20-7:50: Mean.js: A Yeoman Path to the MEAN Stack – Scott Davis

The MEAN stack (MongoDB, ExpressJS, AngularJS, NodeJS) is a compelling new way to build modern web applications, but integrating these separate projects can be a daunting tasks, especially for newcomers. Thankfully, Mean.js offers a cohesive stack, plus a set of Yeoman generators to making getting started and ongoing development efforts easier.

In this talk, you’ll learn how each one of these pieces of technology complement each other. But this is more than a simple change in letters — the move from relational databases to NoSQL and from server-side MVC to client-side MVC represents a major shift in architecture and mental models. Come see how these four independent pieces of technology work together to form the “new way” of doing web development, and how Yeoman ties together all of the loose strings.

6:20-7:10: Future of Development and the Cloud – Ken Sipe

A large change is afoot in software development. Baby steps have lead the way noted by continuous delivery efforts, virtual machines and service oriented architecture. I will reveal my team’s research results as part of R&D on the future of cloud. It is clear the next steps in cloud development are through virtualized applications and application containers (not virtual machines). This movement has already started and is being used at dotCloud, twitter, foursquare, AirBnb and Baidu just to name a few. The technology will have greater acceptance and reach with built in support in RedHat Linux schedule to have a public release in April 2014.

This session will cover the future of cloud development using docker and mesos and how it will create a commoditized cloud solution set and how it will change software development.

7:10-7:30: Break

7:30-8:20: Advance Spock – Ken Sipe

The Spock unit testing framework is on the verge of a 1.0 release and has already proven itself to be the next generation thinking on how to test Java production code. Spock hands down is the best way for developers to mock and test Java applications. One of Spock’s great features is the ability to write your own custom extensions.

This session is a fast paced (not for beginners), code centric view on how to use the advanced features in spock including custom extensions and interceptors.

About Ken Sipe:

Ken has worked with Fortune 500 companies to small startups in the roles of developer, designer, application architect and enterprise architect. Ken’s current focus is on enterprise system automation and continuous delivery systems.

Ken is an international speaker on the subject of software engineering speaking at conferences such as JavaOne, JavaZone, Jax-India, and The Strange Loop. He is a regular speaker with NFJS where he is best known for his architecture and security hacking talks. In 2009, Ken was honored by being awarded the JavaOne Rockstar Award at JavaOne in SF, California and the JavaZone Rockstar Award at JavaZone in Oslo, Norway as the top ranked speaker.

Any direct employee of a company, in attendance, may also announce open Java Developer positions within their company.

6:30-7:50: Main talk – JSON at work: Overview and Ecosystem

JSON is more than just a simple replacement for XML when you make an AJAX call. JSON is becoming the backbone of any serious data interchange over the Internet. There are emerging standards and best practices that can be used to harness the energy and enthusiasm around JSON to build truly elegant, useful, and efficient applications. If you’re already using JSON, you may be thinking:
• What else is there to talk about?
• What additional tools and standards are available, and why do they matter?
• Everything is great, so how would these tools and standards help?

If you’re not using JSON, you may be wondering:
• Why use it?
• Where does it fit?

In this presentation, we’ll cover:

JSON Overview
• JSON Beginnings – language overview, best practices, and the JSON Ecosystem
• JSON Tools

The JSON Ecosystem
• Structuring JSON (JSON Schema)
• RESTing with JSON – modeling, prototyping, and testing
• Text Search with JSON

Attendees will learn how to leverage JSON in new ways to enhance their architecture and development efforts.

About Tom Marrs

Tom Marrs is a Technical Architect at Perficient, where he specializes in RESTful Web Services and Service-Oriented Architecture (SOA). He designs and implements mission-critical web and business applications using the latest SOA, Ruby on Rails, JSON, HTML5, JavaScript, Java/EE, and Open Source technologies.

Tom is currently authoring JSON at Work for O’Reilly, and wrote the Core JSON Refcard for DZone (the #1 downloaded Refcard in 2013). Tom is also a speaker at the No Fluff Just Stuff (NFJS) and Great Indian Developer Summit (GIDS) conferences.

6:10-7:00: Spring Boot: More Spring, Less Configuration – Craig Walls

Spring offers a number of configuration options: XML configuration, Java configuration, and Groovy configuration to name a few. To some degree, component-scanning and autowiring help eliminate some explicit configuration. But in general most Spring applications require some essential “bootstrap” configuration to enable key functionality. What’s the right way to build Spring applications when there are so many choices?
What if I told you that configuration was optional?
What if I told you that it is entirely possible to write a Spring application that is short enough to broadcast *twice* in a single tweet?
Spring Boot is an exciting new project that makes it extremely easy to create stand-alone, production-ready Spring applications. Spring Boot takes an opinionated approach to configuring Spring, making it possible to create Spring applications with little or, in some cases, no Spring configuration at all!

7:00-7:15: Break

7:15-8:45: Spring Data – Craig Walls

This session starts with a high-level look at all that the Spring Data project has to offer. Then we’ll dive deeper into a few select Spring Data modules, including Spring Data Neo4j, Spring Data MongoDB, Spring Data Redis, Spring Data JPA, and Spring Data JDBC Extensions.
In recent years, there has been a renewed interest in how data is stored. Although RDBMS has long been treated as a one-size-fits-all solution for data storage, a new breed of datastores has arrived to offer a best-fit solution. Key-value stores, column stores, document stores, graph databases, as well as the traditional relational database are options to consider.
With these new data storage options come new and different ways of interacting with data. Even though all of these data storage options offer Java APIs, they are widely different from each other and the learning curve can be quite steep. Even if you understand the concepts and benefits of each database type, there’s still the huge barrier of understanding how to work with each database’s individual API.
Spring Data is a project that makes it easier to build Spring-powered applications that use new data, offering a reasonably consistent programming model regardless of which type of database you choose. In addition to supporting the new “NoSQL” databases such as document and graph databases, Spring Data also greatly simplifies working with RDBMS-oriented datastores using JPA.

About Craig Walls:

Craig Walls has been professionally developing software for over 17 years (and longer than that for the pure geekiness of it). He is a senior engineer with SpringSource as the Spring Social project lead and is the author of Spring in Action and XDoclet in Action (both published by Manning) and Modular Java (published by Pragmatic Bookshelf). He’s a zealous promoter of the Spring Framework, speaking frequently at local user groups and conferences and writing about Spring and OSGi on his blog. When he’s not slinging code, Craig spends as much time as he can with his wife, two daughters, 5 birds and 3 dogs.
