Presentation: Adding HTML5 to your Native Android Application

There are many reasons for integrating web content into your native Android applications, for example formatting and styling text or reusing content between platforms. Either way, a thorough understanding of how the web component works, and what you can and can't do with it, is the key to successfully implementing a hybrid application.

In this presentation the different techniques used to integrate HTML5 content into an native Android application will be demonstrated.

The audience will learn how to communicate between Android and the web component, customizing the web component, taking care of resource loading, handling errors, and making the web view blend into the native application.

Presentation: Are Your GC Logs Speaking to You

Getting GC logs is cheap and easy. Just set a couple of switches on the command line and you'll be given the insight into what this performance critical piece of the JVM is up to. For example, many applications are starved for memory in at least one of their internal memory pools. A simple check of the GC logs will tell you if your suffering from starvation. That same data can then be used to calculate a configuration that can result in huge differences in the performance of your application. But it's not only starvation that can be a problem. Having too much memory or an unbalanced configuration can be equally problematic. Or your problem may be as simple as your application's calling System.gc(). All these conditions can be, and in some cases, can only be, diagnosed by listening to what the logs are telling you. In this session we will look some interesting GC logs as well as tools that can be helpful in identifying anti-performance conditions.

Presentation: BeagleBoard, RasberryPi, HTML5 and Java

Usually Java developers do not create code for embedded devices because there was no good Java support on these devices. Oracle figured out that there is a huge market for embedded devices and decided to support Java and JavaFX on hardware like the very popular Raspberry Pi and the BeagleBoard xM. With Java technology available on these platforms it's very interesting to see what you can do with this. This session will give you a short overview on the available technologies and will explain the interaction between different technologies and where they make sense. The uses case will be a temperature monitoring application where a Raspberry Pi running on Java7 embedded is measuring the temperature and sends the measured data to other devices. One of these devices is a BeagleBoard xM running Java7 incl. JavaFX for ARM which is visualizing the measured data from the Raspberry Pi on a touch screen. Also involved in the use case will be a desktop application running JavaFX to visualize the data and at least a mobile device visualizing the measured data using HTML5 Canvas.

Tutorial: Behaviour Driven Development with Cucumber for Java

Cucumber has been around a long time in the Ruby world. It is a popular tool that allows development teams to describe how software should behave in plain text. The text is written in a business-readable domain-specific language and serves as documentation, automated test and development-aid - all rolled into one format. Cucumber-JVM has been available to the Java community since March 2012.

I will develop an example where we can see how a model will grow from the desired external behaviour. The developed model doesn't yet have a GUI. I will extend the example with a GUI without changing the wanted behaviour and test it using Selenium.

Feature: A system need to be developed to show BDD
-Given a requirement
-When we develop a model
-Then we have a working system

Feature: Add GUI to the system developed
-Given a model
-When we add a user interface
-Then we will not need to change the specifications

I will finally show you how Cucumber can be fitted into your continuous integration/delivery system using Maven and thus be a crucial part of your automated acceptance test suite.

Presentation: Continuous Delivery Patterns for Large Software Stacks

We will look at common patterns for building larger software stacks and discuss their advantages and disadvantages. We will also present a new build and promotion patterns that scales even with very large software stacks and allows you to integrate as early as possible but at the same time keep the delivery pipeline for new features flowing. This is a critical problem for many teams. The presenter will share many stories of real life projects, how they were affected by a dysfunctional pipeline and what it took to improve their situation. There are quite a few larger projects for which a naive practice of early integration between their components lead to constant breakages and a defect delivery pipeline. Thus they were not capable to successfully build a new version of the software stack for days or even weeks. Obviously the problem of that is dramatic as no regular manual testing and capacity testing is taking place. Not only is this a massive waste of testing resources, it also leads to very long and therefore expensive feedback cycles that severely affect your time-to-market of new features. It also a likely source of conflict between the CI team and software development, as with no other means at hand, there is a desire to create stability by not adding new features or doing important refactorings.

Presentation: Continuous Delivery: from Dinosaur to Spaceship in 2 years

The SAP ID Service is SAP's identity management system for its websites and cloud operations. The team that built it came from a background of writing web applications in Java 1.4 for an ageing and proprietary platform where it took up to a week just to deploy a new release after it had passed mostly manual QA. With the SAP ID Service project starting in 2010 the team rebooted itself: we adopted Scrum and started building the SAP ID Service using a lean, modern and standards-based application server built from open source components and using Continuous Delivery for build, test and deployment. We are now at the stage where each commit leads to a build with automated test coverage via Cucumber followed by a blue/green deployment to a production-like QA landscape which is provisioned from a cloud and configured automatically using Chef. A similar deployment to production is just a couple of clicks away, and the cloud-based technology used for this also enables developers to provision their own landscapes using a simple web-based tool. This talk will describe our journey, not only sharing our experiences but also welcoming questions and stories from others in the room.

Quickie: Creating a Configuration Standard for Java EE

A recurring problem that developers and devops face is when they deploy an existing Java EE application in a different environment and want to configure it for the new environment without having to crack open the archive. We will introduce a potential JSR proposal that will go about solving this problem by defining a new Java EE configuration service. Such a service would provide the ability to create one or more configurations independent of the applications that use them. We will describe how such a service could provide other kinds of configuration features as well, including tenant-based configuration, configuration change notification, versioned profiles, and more. Come see how Java EE is getting more devops friendly!

Hands-on lab: Hands-on Lab: Deadlocks and Concurrent Testing in Java

One of the hazards of multi-threaded code is that if we are not careful, we might cause a deadlock in our program. The simplest of these is the "deadly embrace", where locks are acquired by multiple threads in different orders. The simple deadlocks can be detected automatically with the deadlock detection tool in the ThreadMXBean. However, there is another class of deadlock that requires us to analyze the stack traces of all the threads. In this hands-on-lab, we will explain what causes deadlocks and how we can find them. You will then be given a body of code to test for deadlocks using the techniques learned. We will also present techniques for testing concurrent code and show some of the pitfalls where the HotSpot profiler overoptimizes our code, thus leading either to code that does not fail, though it should, or that only fails in certain JVMs.

Presentation: How To Do Kick-Ass Software Development

With Kick-Ass Software Development you actually get stuff done. Feedback cycles are short, code quality is awesome and customers get the features they lust after. Less mangers managing, less testers testing and less IT-operators operating. The developers take the power back, making them much happier. Sound like paradise? It is! This session will show you how we do Kick-Ass Software Development at Atlassian. I will talk about how we: use pull requests for better code quality; collaborate fast to develop ideas; avoid meetings to get more stuff done; tighten our feedback loops to fail faster; shorten our release cycles; and work together happily on different continents. It's a great way to develop software and we think it can work in your company, too.

Presentation: How to fail a software project fast and efficiently?

Software development is an industry that has been around for a little bit more than 50 years. There are a lot of really smart people working in this industry. How is it possible that these smart people are so good at failing? How can we as an industry continue year after year with failing or really slow development?
There are many anti patterns that can be applied to software projects.
We will look at a selection of these anti patterns and see why they are so bad and the problems they contribute with.

Just looking at bad examples may be depressing. But if you can identify a bad example in your own project or product then you have a chance to do something about it. Understanding and accepting that you have a problem is always the first step to fix it.

Presentation: Java and the Machine

In Terminator 3 - Rise of the Machines, bare metal comes back to haunt humanity, ruthlessly crushing all resistance. This keynote is here to warn you that the same thing is happening to Java and the JVM! Java was designed in a world where there were a wide range of hardware platforms to support. It's premise of Write Once Run Anywhere (WORA) proved to be one of the compelling reasons behind Java's dominance (even if the reality didn't quite meet the marketing hype). However, this WORA property means that Java and the JVM struggled to utilise specialist hardware and operating system features that could make a massive difference in the performance of your application. This problem has recently gotten much, much worse. Due to the rise of multi-core processors, massive increases in main memory and enhancements to other major hardware components (e.g. SSD) means that the JVM is now distant from utilising that hardware, causing some major performance and scalability issues! Martijn Verburg will take you through the complexities of where Java meets the machine and loses. He'll give up some of his hard won insights on how to work around these issues so that you can plan to avoid termination, unlike some of the poor souls that ran into the T-800...

BOF: Java EE.express BOF

Java EE has a broad array of technologies that can be leveraged in almost any enterprise scenario. While the mature breadth of the platform has definitely been one of its strengths, community involvement has also been a major contributor to its success. As software trends change over time the community voices their opinions about which new technologies and practices should be included or made optional in subsequent platform releases.
This BoF will be an opportunity for developers to express their views about the overall direction of Java EE, as well as make suggestions for features and improvements to individual specifications.
Come out and be heard? or just listen to what others have to say and assert your agreement/disagreement over their opinions!

Presentation: Nashorn: Optimizing JavaScript Execution on the JVM

There are many implementations of JavaScript, meant to run either on the JVM or standalone as native code. Both approaches have their respective pros and cons. The soon-to-be open sourced Oracle Nashorn JavaScript project is based on the former approach. This presentation goes through the performance work that has gone on in Oracle?s Nashorn JavaScript project to date in order to make JavaScript-to-bytecode generation for execution on the JVM feasible. Aside from covering the Nashorn project itself, we show that the new invoke dynamic bytecode gets us part of the way there but may not quite be enough. Nashorn is also the first JavaScript runtime in the world to achieve 100% EcmaScript compliance. What other tricks did the Nashorn project use? The presentation also discusses future directions for increased performance for dynamic languages on the JVM, covering proposed enhancements to both the JVM itself and to the bytecode compiler.

Presentation: Netflix OSS Cloud Architecture

This talk presents a general overview of the Netflix cloud architecture built upon the Amazon Web Services (AWS) foundation. It covers how we use existing AWS features to improve the manageability of our cloud objects, and how we add a few abstractions to tie the AWS objects neatly together. It also covers some of the Netflix OSS tools (and a few non-OSS), and how they fit into this picture to help run the show.

Presentation: OSGi vs Spaghetti - Part II, The Enterprise strikes back

Software engineering sometimes seems like a struggle against spaghetti. Without lots of care, modern projects risk becoming an unwieldy tangle of closely-coupled code whose behaviour and dependencies are mostly unknowable. OSGi can help keep the complexity at bay, but until recently OSGi didn't play very well with modern enterprise programming models such as dependency injection, WARs, JPA, and application deployment. The Enterprise OSGi programming model is changing all this, and can help keep your applications from descending into a noodly mess. This session will discuss the basics of OSGi modularity, and demo the build tools, middleware, and architectural principles which can be used to turn a chunky WAR into a lean, mean, extensible OSGi web application.

Presentation: Patterns for key-value stores

As nosql gathers more and more momentum I have discovered that there is a need for good patterns. You want to organize the data as well as possible. With good organising it will be easier to find the data again.This can be a real challenge when you have little or no experience dealing with key-value stores. If you use good patterns, your database scheme will make sense, you will get better performance and hopefully your code will look better as well. My presentation with look at patterns for all key-value stores, and patterns for Redis, Riak and end with a peek into what good patterns + Redis + Riak can give you.

Presentation: Phaser and StampedLock Concurrency Synchronizers

In Java 7, the Phaser was introduced to give us a more flexible form of CountDownLatch and CyclicBarrier. In this presentation, we will show examples of how Phaser can be used to communicate between threads and how it simplifies your code. A new construct that is being worked on is the StampedLock. This new type of locking mechanism allows readers to access state concurrently, much like the ReadWriteLock. However, it is much more efficient for readers, since you can do so in a more optimistic fashion. In this presentation, we will show how to use it and what some of the common coding patterns are that we can use.

Tutorial: Practical Guide to Modularity in the Cloud Age

Java EE 6 is an awesome platform and probably the best choice for any kind of enterprise (web) application today. But what about taking it to the next level? How do you design a system that can evolve for many years in production? And how do we run this stuff in the cloud?

Designing a system that can evolve without creating a maintenance nightmare is far from trivial and there are no silver bullets to do this correctly. A service oriented, modular architecture will help a lot to achieve this goal. Modularity forces separation of concerns which, when combined with a service oriented architecture, enables you to replace parts of a system without breaking others. The only mature modularity approach for Java is OSGi. OSGi is a framework that enables low-level modularity and services, but it is not an application framework like Java EE, i.e. you still need APIs to create web applications, use transactions, access data sources etc. Without these APIs you will have a hard time to actually build applications. Unfortunately OSGi and Java EE did not interoperate well in the past; it was very challenging to mix both. But what if we want modularity in our architecture, but also the ease-of-use of Java EE 6?

Luckily times are changing. All major application servers are getting support for deploying mixed Java EE and OSGi applications. This makes it possible to deploy OSGi bundles that contain Java EE 6 code such as EJBs, JPA and JAX-RS resources. CDI can be used to inject OSGi services and EJBs can easily be exported as OSGi services too.

The next question is how to deploy this in the cloud. Of course you could use one of the existing PaaS providers, but these basically deploy your old, monolithic WAR/EAR in the cloud. This doesn't fit modularity very well. How can you update just parts of a running application without breaking the rest of it? We will introduce Apache ACE, an Open Source Provisioning Platform to deploy OSGi bundles (containing Java EE code) and other artifacts to the cloud.

In this presentation you will learn the following things:

1. Understand the benefits of a modular code base
2. Learn how to mix OSGi and Java EE
3. Manage cloud deployments using Apache ACE

..and of course there will be lots of live coding!

Presentation: Project Lambda: Functional Programming Constructs and Simpler Concurrency in Java SE 8

The big language features for Java SE 8 are lambda expressions (closures) and default methods (formerly called defender methods or virtual extension methods). Adding lambda expressions to the language opens up a host of new expressive opportunities for applications and libraries. You might assume that lambda expressions are simply a more syntactically compact form of inner classes, but, in fact, the implementation of lambda expressions is substantially different and builds on the invokedynamic feature added in Java SE 7. This session will explain the ideas behind lambda expressions, how they will be used in Java SE 8 and look at some of the details of their implementation.

Presentation: Real-Time Delivery Architecture at Twitter

With hundreds of millions of users, Twitter operates one of the world's largest real-time delivery systems, large enough and pervasive enough to exert noticeable "pressure" on the overall internet itself. At steady state, Twitter receives thousands of tweets a second that it needs to deliver to disks, in-memory timelines, email, and mobile devices. The name of the game for Twitter is "now", so those deliveries, which multiply according to the graph of who follows whom, need to occur in real-time. In this session, we will dive into both the "write path" and "read path" of Twitter to understand the architecture which supports those tweets, and also how Twitter serves them through one of the world's largest web sites.

Presentation: Scala your Android

Many of us are aware that it's possible, and quite easy, to use some other language than Java on Android's DVM, but still not many have actually tried it. As it turns out, one of the best languages fit to do Android development is... Scala. Remember how you had to override methods to create menus, and sharing those was quite hard due to Java's inheritance model? Well, Scala's traits solve that problem for you. Or how much boilerplate (with explicit type casting) you had to write to find a view by id? Say hello to Typed Resource! And there's even more pain to be relieved by using some of Scala's features - which, oddly enough, seem to be a perfect `match` for `lazy` Android development... And I assume you're already on the Scala Collections drug? If not - be prepared to get addicted. During this session we'll explore those, and some more techniques that you can use to Develop your Android apps with Scala as well as problems you might encounter.

Tutorial: Secrets of an Agile Architect

We architects love a good framework. We like our abstractions, we like to design "enterprise" solutions, we like to mandate complex algorithms, or better yet to prescribe toolkits to enable other teams to implement complex algorithms under our expert guidance. If it looks like a good idea we slap the label "pattern" on it and tell everyone to do it.

Ok, maybe that isn't you. But it's likely you work in an organisation where the other guys do. So what can you do about it? Is this the only way to do architecture?

This toturial looks at strategies and techniques to incrementally architect your way out of a legacy mess, and to set up new applications for success.

Keynote: Simplicity: the Way of the Unusual Architect

It is often said that the difference between architecture and design is one of scale. Architects are concerned with "big" design and "big" integration. As developers become architects and architects become enterprise architects, the systems they build grow ever bigger and more complex. But does big necessarily need to mean complicated?

In this talk Dan argues for a new appreciation of simplicity, using examples from systems design, enterprise integration, build and deployment, and provides strategies to help you extract the simple essence from complex situations and problems, and to distinguish the simple from the simplistic.

Presentation: Strategies for Loose Coupling in Large Java Desktop Applications

Large Java desktop applications are found throughout the software world, typically in back offices doing behind the scenes work, for example, in air traffic control, defense force simulations, risk managament analysis, and, generally, in the processing and visualization of large sets of data. Such applications will never completely run in the browser, on a tablet, or on a mobile phone.

These applications, typically very well hidden, are doing mission critical work. In this session, you will learn strategies for simplifying the work that needs to be done when creating and maintaining such applications in Java. With Swing or JavaFX (or both) on the frontend, a stable and powerful framework beneath, and modularity natively built in, you will see how the infrastructure of NetBeans can be leveraged as the basis of any Java desktop application, from NATO to Swedish defence force, and from finance to software development tools.

The session focuses on how to create loosely coupled features in large Java desktop applications and includes a panel, with discussion, and interaction from participants. By the end you will know everything to get started creating pluggable and maintainable applications yourself. Stand on the shoulders of giants, stand on the NetBeans rich client platform.

It has been proven in numerous enterprise settings as an ideal solution combining flexibility and convenience, and yet the frameworks that provide dependency injection must often choose between either flexibility or simplicity, often because of limitations of the host language.

Scala offers the flexibility, power and abstraction necessary to provide a truly simple but powerful solution to the problem. SubCut (Scala Uniquely Bound Classes Under Traits) is a library that anyone can learn and use within minutes, and which will scale up to large software installations without problem. It is actually a combination of dependency injection and service locator patterns, and relies on the power of Scala to make the difficult seem easy. Some of the features that make SubCut unique include:
* Inject instances of classes, but still use "new" to create them
* No mutable state required, injected values can be assigned to vals in the class
* Immutable configuration (with a mutable builder to make life easy)
* A readable, simple DSL that leads you through the process of binding traits to implementation
* Deep type safety, e.g. inject a List[Int] and a List[String] from the same configuration with different values
* Lightweight identification of configuration values with symbols or names
* Compatible with any other library without needing a compatibility layer
* Compile time verification of the presence of a configuration module for any injected class
* Easy modification and combination of configuration modules at runtime (e.g. for testing) but with the original configuration remaining immutable
* A completely optional compiler plugin for drop-dead simple injection
* Works extremely smoothly with all IDEs

SubCut 1.0 got some good use from interested developers, and led to a number of improvements from lessons learned. The recent SubCut 2.0 has improved on most of the features of the original release, without getting much more complicated as a result.

Presentation: Surviving the Zombie Apocalypse of Connected Devices

The zombie apocalypse has begun.
The number of different types of connected devices is increasing. We have already built ourselves a large amount of code duplication between client applications (both native apps and web apps) and it's only getting worse. Also, cheap low-profile devices are getting bigger market shares and users will still expect a good experience when using our software.
To solve the problem of code duplication on the clients, we need to pull as much code as we can from the clients back to the server. A good way to achieve this is to build a Hypermedia API and to use HTML as the media type for the API. A nice side-effect of this is that we can show the received HTML directly to the user, which will be good enough for a majority part of a client application.
The problem of low-profile devices is best solved by using Progressive Enhancement, which will allow us developers to provide the best experience that the device is capable of delivering.
Finally, combining HTML Hypermedia APIs and Progressive Enhancement will allow us to have a single endpoint for our web and our API. Grab your keyboards and join the resistance!

Presentation: The Wearable Application Server and Other Adventures in Software Engineering

Mobile technology has so far mostly been confined to the client side, for fairly obvious reasons - traditionally, clients are mobile, and servers are not. However, not only is hardware getting smaller, servers are too. When your application server can run on pocket-sized £25 hardware it opens up some pretty cool possibilities - your server is literally lightweight. Not only can you have location-based services, you can have locatable servers. Servers can run on phones, they can run on the Raspberry Pi, and so they can go almost anywhere you can think of. Modularity gives software the flexibility it needs to cram into these tight spaces without sacrificing power. This talk will demonstrate developing and deploying a web application to an application server embedded in a silly hat.

Tutorial: Thinking and Programming in Functional Style

Functional programming has been around for a while, however, they have sharply raised to prominence on the JVM with the emergence of languages like Scala, Clojure, Groovy, and JRuby. Programming in functional style is not about picking a set of syntax, it is thinking in a particular idiomatic style and programming using a set of constructs. One of the better way to learn this is by doing it. In this workshop, we will take ten different tasks, discuss how to do them with the all-too-familiar imperative style and then how to program it using functional style. We will then implement our design for each task using a language that provides functional style of programming on the JVM.

Presentation: WebSocket and Java EE: A State of the Union

Java EE is beginning its climb into the cloud. In addition to updates to existing technologies such as JPA and EJB, Java EE 7 is introducing new technologies such as WebSocket that aim to provide bidirectional, asynchronous communication between a client and a server. This session introduces the protocol itself, discussing the various ways it differs from HTTP. It also touches briefly on how it differs from existing asynchronous approaches. From there the presentation moves to examples of existing APIs that provide support for the protocol and then discusses the current state of the JSR and what remains to be done before final delivery of Java EE 7 in the first half of 2013.

Presentation: What Every Hipster Should Know About Functional Programming

Different programming paradigms serve different purposes. Systems programmers prefer tools that are dumb, imperative and close to the metal. Enterprise programmers prefer tools which foster complexity, increasing billable hours and the client's dependency on the developer.

And, let me just come clean and admit it, functional programmers do it for that delicious feeling of superiority that comes from looking down your nose at the normals in their caves banging together for loops and mutable state to make fire.

Treat yourself to a crash course in the vocabulary of functional programming: lambdas, higher order functions, purity and immutability, the infinite opportunities to throw the word "monad" in the face of anyone who thinks an ironic moustache is enough to justify all that self-assured smugness these days. You'll never have to lose a programming argument again once you've learned where to casually toss terms like "applicative functor" and "Kleisli triple" into the conversation.

This is the War of the Hipsters. Arm yourself now, before it goes mainstream.

Video: Introduktion

Quickie: Why you should use a Java Cloud platform? Because it's Easy!

Are you still struggling with your own server set-ups? We will show some of the benefits with deploying your application on a Java Paas Cloud instead. Choose your software stack, set the limits for autoscaling and in just a few seconds your environment will be up and running! Without installing and configuring your own. These days you don't need to code against third-party APIs - you just upload your application and start. Simply upload your application package and choose the right environment. If your environment has multiple computing instances, all of them will automatically be updated with Maven and Ant plugins, deployment as simple as mvn:deploy. As your traffic grows, CPU and RAM automatically scale your application needs to handle the load. If your traffic decreases,it will immediately reduce the resources again.

Come and see the next generation of Java hosting platforms which can run and scale ANY Java application with no code changes required! We will use Jelastic, The Duke Choice Award winning cloud platform to exemplify what a modern Java PaaS will provide for you!

Presentation: Will It Float [in Java]?

In this session we will undertake a rigorous, empirical methodology to find out the current state of Java on devices of all sizes and shapes. Using the time-tested technique of technology immersion, the capabilities of running different devices in Java will be physically demonstrated. We will uncover some surprising developments in Java on mobile, embedded, and consumer devices with a look into the future of Java machine-to-machine (M2M) applications. This session will be run by an expert in the field of device buoyancy, so audience members are strongly cautioned against trying these experiments on their own!
