Building Maintainable Javascript with Coffeescript

Friday 1:15 PM - David Bock

CoffeeScript is a little language that compiles into JavaScript. Underneath all of those embarrassing braces and semicolons, JavaScript has always had a gorgeous object model at its heart. CoffeeScript is an attempt to expose the good parts of JavaScript in a simple way.

The golden rule of CoffeeScript is: "It's just JavaScript". The code compiles one-to-one into the equivalent JS, and there is no interpretation at runtime. You can use any existing JavaScript library seamlessly (and vice-versa). The compiled output is readable and pretty-printed, passes through JavaScript Lint without warnings, and runs in every JavaScript implementation.

Cryptography on the JVM: Boot Camp

Friday 3:15 PM - Matthew McCullough

Does your application transmit customer information? Are there fields of sensitive customer data stored in your DB? Can your application be used on insecure networks? If so, you need a working knowledge of encryption and how to leverage Open Source APIs and libraries to make securing your data as easy as possible. Cryptography is quickly becoming a developer's new frontier of responsibility in many data-centric applications.

Pragmatic Architecture

Friday 3:15 PM - Ted Neward

Building an application is not the straightforward exercise it used to be. Decisions regarding which architectural approaches to take (n-tier, client/server), which user interface approaches to take (Smart/rich client, thin client, Ajax), even how to communicate between processes (Web services, distributed objects, REST)... it's enough to drive the most dedicated designer nuts. This talk discusses the goals of an application architecture and why developers should concern themselves with architecture in the first place. Then, it dives into the meat of the various architectural considerations available; the pros and cons of JavaWebStart, ClickOnce, SWT, Swing, JavaFX, GWT, Ajax, RMI, JAX-WS, , JMS, MSMQ, transactional processing, and more.

Groovy Web Services, Part II: SOAP and JAX-WS

Friday 3:15 PM - Kenneth Kousen

Although RESTful web services have gotten better press, SOAP-based web services are often the backbone of many large enterprises. The user-friendly advances in JAX-WS 2.* make developing such services much easier. As with most Java topics, Groovy simplifies the development of web services as well. Since it is particularly well-suited to XML processing, Groovy is quite helpful in the web services and SOA worlds.

Developing Social-Ready Web Applications

Friday 5:00 PM - Craig Walls

Businesses are increasingly recognizing the value of connecting with their customers on a more personal level. Companies can utilize social networking to transition from "Big Faceless Corporation" to "Friend" by taking their wares to the online communities where their customers are. In this age of social media, those communities are found at social network sites such as Facebook, Twitter, and LinkedIn. In this session, you'll learn how to build applications that interact with the various social networks. We'll also look at Spring Social, a new feature in the Spring portfolio that enables integration with social networks in Spring-based applications.

Simpler Cryptography with 3 JVM Libraries

Friday 5:00 PM - Matthew McCullough

Cryptography at first seems like a daunting topic. But after a basic intro and the leverage of the Java Cryptography Extension (JCE), it seems downright feasible to add encryption and decryption capabilities to your application.

Developers weren't satisfied with just the JCE and its plug-in concepts though. Over the last few years, framework architects have made strides in either wrapping or re-writing the approachable JCE in more convenient APIs and fluent interfaces that make effective and accurate crypto down right simple.

Explore three of these libraries -- Jasypt, BouncyCastle and KeyCzar -- and how they can be leveraged to make your next Java cryptography and data security effort a simple exercise and not a tribulation.

Architectural Kata Workshop

Friday 5:00 PM - Ted Neward

Fred Brooks said, "How do we get great designers? Great designers design, of course." So how do we get great architects? Great architects architect. But architecting a software system is a rare opportunity for the non-architect.

The kata is an ancient tradition, born of the martial arts, designed to give the student the opportunity to practice more than basics in a semi-realistic way. The coding kata, created by Dave Thomas, is an opportunity for the developer to try a language or tool to solve a problem slightly more complex than "Hello world". The architectural kata, like the coding kata, is an opportunity for the student-architect to practice architecting a software system.

Cascading through Hadoop: A DSL for Simpler MapReduce

Saturday 3:15 PM - Matthew McCullough

Hadoop is a MapReduce framework that has literally sprung into the vernacular of "big data" developers everywhere. But coding to the raw Hadoop APIs can be a real chore. Data analysts can express what they want in more English-like vocabularies, but it seems the Hadoop APIs require us to be the translator to a less comprehensible functional and data-centric DSL.

The Cascading framework gives developers a convenient higher level abstraction for querying and scheduling complex jobs on a Hadoop cluster. Programmers can think more holistically about the questions being asked of the data and the flow that such data will take without concern for the minutia.

We'll explore how to set up, code to, and leverage the Cascading API on top of a Hadoop sample or production cluster for a more effective way to code MapReduce applications all while being able to think in a more natural (less than fully MapReduce) way.

Complexity Theory and Software Development

Saturday 3:15 PM - Tim Berglund

Some systems are too large to be understood entirely by any one human mind. They are composed of a diverse array of individual components capable of interacting with each other and adapting to a changing environment. As systems, they produce behavior that differs in kind from the behavior of their components. Complexity Theory is an emerging discipline that seeks to describe such phenomena previously encountered in biology, sociology, economics, and other disciplines.

The Busy Java Developer's Guide to Akka

Sunday 11:00 AM - Ted Neward

With the rise of multi-core processors, and their growing ubiquity (on client machines, to say nothing of the server machines on which Java applications most frequently execute), the need to "program concurrently" has risen from "nice-to-have" to "mandatory" requirement, and unfortunately the traditional threading-and-locking model is just too complicated for most Java developers--even the brightest of the lot--to keep track of with any degree of reliability. As a result, numerous new solutions are emerging, each of them with their own strengths and weaknesses, leaving the Java developer in a bit of a quandary as to which to examine.
