Abstract: Netflix has moved its production services from being completely datacenter-based, to being primarily cloud-based in a little over a year. This talk will briefly explain why we did it and why we chose Amazon's AWS. The talk will then delve into the evolution of our build and deployment architecture, starting with how our orignal monolithic DC-based SQL-tied webapp was built and deployed, and then detailing the evolution of our continuous integration systems which helped prepare us for the cloud move. And finally, it will cover our current full build pipeline and deployment system which keeps us agile in the cloud now by providing quick turnaround, and rapid roll-out and recovery.

Abstract: FindBugs is a static analysis tool that finds coding mistakes in Java programs. It is widely popular, with more than a million downloads. In a student involving hundreds of engineers at Google, the issues identified by FindBugs were evaluated as should fix or must fix issues 81% of the time. However, many projects and developers use FindBugs on an ad-hoc basis, with individual developers running FindBugs sporadically. Some projects use FindBugs as part of their continuous build system, but find themselves unsure of the return on their investment and wondering if there might be a more effective way to use FindBugs. When first applying FindBugs is a large project and seeing hundreds or thousands of issues, others simply give up on using FindBugs. I'll briefly review FindBugs, and describe techniques for cost-effective integration of FindBugs into the software development process for medium to huge software projects, with a focus on new features available in FindBugs 2.0. Topics include how to customize FindBugs to prioritize and filter issues important to your project, how to store bug data in a cloud so that everyone working on the project shares information about when the issue was first seen and whether people think the issue is important to fix, and ways to use annotations to help FindBugs detect even more errors in your code.

Abstract: Functional programming is in the air. The most common question in java programmers mind is whether it is useful and possible to do functional programming(FP) in Java ? I will start of with a quote from Timothy Budd, “Research results from the psychology of programming indicate that expertise in programming is far more strongly related to the number of different programming styles understood by individual than it is the number of years of experience in programming.” So FP will help you to become a better Java developer. And the good news is FP is language agnostic. Its a style that you learn and can use in almost all programming languages. Outline of the presentation - Introduction to FP with examples written in Java - Why FP is important to learn and explain the benefits of FP in enterprise software development - Overview of the FP libraries available in Java (functionaljava, lambdaj etc)

Presented By: Nilanjan Raychaudhuri

About the Speaker: I am Nilanjan Raychaudhuri working for Livingsocial. Previously worked in companies like Pillar technology and Thoughtworks. I have managed and developed software solutions for more than 12 years and specializing in integrated multi-tiered web and server applications. I am known for hard work, well-tested code, and clean OO design. I believe in high-discipline agile methodologies, customer focus, simple tools applied elegantly, and continuous improvement. I believe I am almost unique among programmers having strong skills with both databases and objects together. I have a passion for the elimination of duplication in design, code, data, and most of all – effort. I write software for a living. But since I enjoy creating things and solving problems, I also write software on my pastime. I am currently working on scala-webmachine (restful resource framework). In past I worked on other open source projects like Panopticode, scala-inline and autotest4j. When I am not working on projects I play with functional programming and DSL. Currently writing a book on Scala programming language called “Scala in Action” from Manning publication.

Abstract: Google Web Toolkit is five years old now, and has changed greatly since it was launched at JavaOne in 2006. Most already know that GWT allows you to cross-compile Java into JavaScript for HTML applications, but there is much more to it. In this session we will look at the best-practices that are baked into GWT. These include safety and optimization, but also a lot of things many people developing HTML applications might know they should be doing, but don't because it is hard. In short, GWT can write your code better than you can. If you haven't worked with GWT, or haven't looked at it in years, this session will provide and solid overview of all the fundamental components included in the toolkit. Outline I. The Original Release a) Perfect caching strategies b) i18n c) Image compositing d) Compression optimization e) Testing, Packaging II. 1.x Evolution a) SOYC b) Improved compression c) JavaScriptObject Overlay d) Handlers vs Listeners e) Pluggable dev server III. 2.x Breathrough a) OOPHM b) New Resources System c) Compiled Stylesheets d) data: image inlining e) UIBinder f) Compiler point-cuts g) CSS3 optimized Layout IV. 2.x Evolution a) Improve i18n/RtL support b) SpeedTracer c) Editors framework d) Spring Roo and Data bound widgets V. The Capital-F Future a) More HTML5 b) Stealing from the future! c) Dart/Dash d) SourceMaps

Abstract: The Java SE 7 release is the result of nearly five years of industry-wide development involving open review, weekly builds and extensive collaboration between Oracle engineers and members of the worldwide Java community via the OpenJDK project. Over the past year the OpenJDK community has continued to grow, including the addition of major vendors such as IBM and Apple. In June Oracle announced that the Java SE 7 Reference Implementation will be based entirely on the OpenJDK open source code. The Java SE 7 release includes new features such as small language changes for improved developer productivity, a new Filesystem API, support for asynchronous I/O, a new fork/join framework for multicore performance, improved support for dynamic and script languages, updates to security, internationalization and web standards and much more. In this session, we'll provide an overview of the these new features and highlight the major improvements.

Abstract: JavaFX 2.0 is the next version of a revolutionary rich client platform for developing immersive desktop applications. One of the new features in JavaFX 2.0 is a set of pure Java APIs that can be used from any JVM language, opening up tremendous possibilities. This presentation demonstrates the potential of using JavaFX 2.0 together with alternative languages such as Groovy and Scala. It also will showcase the successor to JavaFX Script, Visage, a DSL with features specifically targeted at helping create clean UIs.

Abstract: With experience based on Java Programming Puzzlers (previously presented with Joshua Bloch), looking at thousands of coding mistakes found by FindBugs, and working with students and developers writing Java code for over 15 years, I'll discuss some common Java coding puzzlers and bug patterns, and techniques you can use to avoid them. While inexperienced developers can be particularly subject to many of these mistakes, they also occasionally bite experienced developers. Many of them are puzzlers, in the sense that they are hard to detect in code reviews, exhibit surprising behavior, and hard to debug. I'll avoid esoteric puzzlers that are largely a theoretical possibility, and focus on real bugs that occur with a distressing frequency in real code, illustrated by examples from current open source software. The talk will be accessible and value both to those new to the Java programming language and those with more than a decade of experience.
