Presentation: A JVM Does What?

Just what the heck is a JVM *supposed* to do? JVMs already provide a host of services. The 'J' part definitely slants the service selection and the 'V' part means that underneath the illusion there's a lot of really cruddy stuff. The success of these illusions has led to the real popularity of JVMs. In particular, JVMs are probably the most popular way to distribute ready-to-use GC technology to the masses, and the 2nd most popular way to distribute ready-to-use compilation technology (just behind "gcc" I'm guessing).

Just what are these illusions? The illusion that bytecodes are fast and have a reasonable cost model : (machine code generation, profiling, JIT'ing). The illusion that you can quickly change the program at any time (dynamic class loading, deoptimization, re-JIT'ing). The illusion of infinite memory (Garbage Collection). The illusion of a consistent threading and memory model (the JMM, volatiles, locks). The illusion of quick time access (i.e. Intel's "rdtsc" is mostly useless for time). The illusion that these other illusions all work on all sorts of machines from cell phones to 1000-cpu mainframes (it's kinda sorta mostly true). But these are not enough! The People cry out for more illusions! The illusion of an Infinite Stack (tail recursion), the illusion that running-code-is-data (closures), the illusion that Integers are as cheap as 'ints' (autoboxing optimizations), or that BigIntegers are as cheap as 'ints' (tagged ints), the illusion that memory supports atomic update (software transactional memory), or the illusion that with enough hard work other language implementation experts can make a JVM run utterly different languages (invokedynamic). Meanwhile, JVM engineers labor under the illusion that they can maintain this giant piggy pile of code, and maybe even expand the provided services without it collapsing under it's own weight.

Here's my take on what services could & should be provided by a JVM, what services probably belong to the next layer up (STMs, new concurrency models), and what services belong to the next layer down (fast time management, sane thread scheduling).

Tutorial: A Practical Introduction To Kanban

Kanban is a software development methodology that implements the pull and flow elements of lean thinking. Learn how to use Kanban as a tool that can enhance other methodologies through visualisation of the workflow to highlight bottlenecks, impediments and other problems, limiting work in process to eliminate waste, and more. This talk introduces Kanban from a practitioners point of view which let you get started with Kanban and lean inspired enhancements right away, regardless of what methodology you use today. We will show the mechanics of visualisation, flow, and how to monitor the flow in order to identify bottlenecks, impediments etc, using animations of real bords created with more than 150 photographs. This method has shown to be very popular and successful when teaching the practice of Kanban to many teams. There will also be a case study of a Scrum team that adopted Kanban. This will give attendees an opportunity to learn and discuss how to apply Kanban to their own team and process.

Quickie: An Intro to Hadoop

Enterprises today collect and generate more data than ever before. Relational and data warehouse products excel at OLAP and OLTP workloads over structured data. The open-source project administered by the Apache Software Foundation known as Hadoop, is designed to solve a different problem: the fast, reliable analysis of both unstructured and complex data. As a result, many enterprises deploy Hadoop alongside their legacy IT systems, which allows them to combine old data and new data sets in powerful new ways. Technically, Hadoop consists of two key services: reliable data storage using the Hadoop Distributed File System (HDFS) and high-performance parallel data processing using a technique called MapReduce. This technology opens the door to new enterprise solutions, as you no longer have to predict how you want to search or query your data in future use cases! This technology is playing a key role in the new trend of Big Data that is taking off in a rapid speed within huge enterprises. Come see this talk to get an intro to Hadoop, what it is, and what it can do for you - and how you can get involved to influence the future!

Presentation: Building iOS applications in Java

Vaadin gives a server-centric programming model for building rich web applications in any JVM compatible language. The presentation shows how this development model can be extended to mobile touch devices, how server-side tooling and languages can be used to build rich applications for mobile and what are the limitations of Vaadin in respect to mobile application development. During the presentation, the programming model is introduced by developing a native looking iPhone and iPad applications for managing enterprise wide address book. This is done step by step to teach you how to use the technology to build iPhone and iPad user interfaces for your existing enterprise applications really fast. In the example, Vaadin TouchKit components are used to make the application look and feel like a native iOS application. The same programming concepts can be used to develop applications for Android, Windows Mobile, Symbian and other mobile platforms with modern web browser and if the native look is not required, they can be programmed with just the core Vaadin Framework. As a conclusion the pros and cons of the programming model of Vaadin are compared to developing mobile web applications using JavaScript with jQuery Mobile and developing native applications using the iOS and Android platform SDKs.

Tutorial: Building Next-generation Enterprise Applications in Java a.k.a. Duke's Duct Tape Adventures

Java EE 6 contains new APIs that revolutionary change the way you can build enterprise level applications with an even stronger focus on ease-of-development and further reducing the need of boilerplate code and configuration. The result is a strongly simplified programming model, while still keeping enterprise features such as transactions, security, load-balancing and fail-over. In this session we'll demonstrate how to use the APIs together to build a portable, full stack enterprise application and solve real-world problems. We'll not only focus on the APIs but we'll also show you how to set up a vanilla Maven build from scratch and do unit and integration testing going into almost all parts of the Java EE 6 specs. At the end we'll discuss the architectural consequences of this simplified programming model. Do we still need business delegates, transfer objects or DAOs? And what about separation of concerns? The session is fun and very interactive while still showing the technology in depth.

Video: Introduction

Presentation: CoffeeScript: JavaScript without the Fail

JavaScript. Love it or hate it, in the web development world it's impossible to avoid it. It was designed in one week by one man at Netscape, just to keep the browser from standardising on something even worse—and it shows. Oh, it's not all bad, but the Good Parts—which actually make up a pretty neat language—are well hidden in among all the Bad Parts, which are there to make you, the JavaScript developer, suffer.

CoffeeScript is a language designed to take the Good Parts out of JavaScript and make a new, concise and beautiful language out of them. It runs anywhere JavaScript does—in fact, it compiles to fairly readable JavaScript—so you can already use it in your web applications and wherever else you've been stuck with JavaScript. In this talk, you'll learn what CoffeeScript looks like, how it relates to the JavaScript you know, and what new features it has to offer. In fact, if you already know JavaScript well, you'll probably be perfectly fluent in CoffeeScript after this—it's that easy. And trust me, your life will be so much better for it.

Video: Introduction

Tutorial: Continuous Delivery

Getting software released to users is often a painful, risky, and time-consuming process. This workshop sets out the principles and technical practices that enable rapid, incremental delivery of high quality, valuable new functionality to users. Through automation of the build, deployment, and testing process, and improved collaboration between developers, testers and operations, delivery teams can get changes released in a matter of hours, sometimes even minutes, no matter what the size of a project or the complexity of its code base. In this workshop we take the unique approach of moving from release back through testing to development practices, analyzing at each stage how to improve collaboration and increase feedback so as to make the delivery process as fast and efficient as possible. At the heart of the workshop is a pattern called the deployment pipeline, which involves the creation of a living system that models your organization?s value stream for delivering software. We spend the first half of the workshop introducing this pattern, and discussing how to incrementally automate the build, test and deployment process, culminating in continuous deployment. In the second half of the workshop, we introduce agile infrastructure, including the use of Puppet to automate the management of testing and production environments. We?ll discuss automating data management, including migrations. Development practices that enable incremental development and delivery will be covered at length, including a discussion of why branching is inimical to continuous delivery, and how practices such as branch by abstraction and componentization provide superior alternatives that enable large and distributed teams to deliver incrementally.

Keynote: Cool Code

In most disciplines built on skill and knowledge, from art to architecture, from creative writing to structural engineering, there is a strong emphasis on studying existing work. Exemplary pieces from past and present are examined and discussed in order to provoke thinking and learn techniques for the present and the future. Although programming is a discipline with a very large canon of existing work to draw from, the only code most programmers read is the code they maintain. They rarely look outside the code directly affecting their work. This talk examines some examples of code that are interesting because of historical significance, profound concepts, impressive technique, exemplary style or just sheer geekiness.

Quickie: Developing Mobile Web Apps with PhoneGap

If you decide today that you want to create a mobile application, you have to decide on a development strategy - especially if you want to target multiple platforms. You can either learn to program from scratch for each platform or you can use a framework that abstracts on top of all of the platforms - like Apache PhoneGap. If you decide to use PhoneGap, you still have decide whether to use a library specially designed for mobile applications - like Sencha or jQuery mobile - or whether to use general libraries like Zepto or jQuery. There are a lot of decisions to make, and there's no one best strategy at this point in the game. In this talk, I'll explain my development strategy, why I chose it, and what I've learnt along the way - so that your own decision process is easier.

Presentation: Developing portable PaaS applications

In demonstrating how the Java cloud library jclouds makes it easy to work with cloud services in a simple, portable way, we've written a bunch of applications that run on many of today's Platform as a Service offerings, including Google App Engine, CouldBees RUN@cloud, Amazon Elastic Beanstalk, OpenShift, Cloud Foundry and Heroku. In this session, we'd like to share our experience in developing and, just as importantly, managing portable Java PaaS applications. We'll set the context by identifying some pointers to help you decide whether a public or private PaaS makes sense for your application, or whether an IaaS solution in a public or private cloud might be more appropriate. We'll then compare PaaS APIs, provided resources and replacements, and discuss ways of separating your core portable business logic from your "PaaS binding". Finally, we'll look at "live-from-IDE" development, continuous integration and deployment options and touch on monitoring and application management in a multi-PaaS setup.

Are you waiting for closures in Java 8 or hoping for more type inference in Java 9? Thinking about switching to Scala or even holding your horses for Ceylon or Kotlin? How about keeping Java where it seems fit, but replacing just its outdated parts with a concise and modern language? What about an enhancement to Java instead of yet another attempt to hire a killer.

Xtend is an open-source programming language hosted at Eclipse.org and built for Java developers. It reuses Java's keywords, terminology and concepts as much as possible, but abandons some dead freight at the same time. Xtend is a very powerful alternative for implementing Java classes and works great with all the existing libraries. Since the language can be seen as a little complementary add-on to Java, it offers many modern language features that you are currently missing in your daily work. Xtend comes with a variety of goodies reaching from type inference over closures and extension methods up to smart string interpolation that make development great fun again. And of course there is powerful Eclipse IDE tooling available.

In this session we will demonstrate why Xtend is so great for everyday programming. You will get an introduction to the seamless integration with the Eclipse Java IDE and an impression of the expressiveness and conciseness of the language.

Presentation: Enterprise Integration Patterns and DSL with Apache Camel

Apache Camel, a very popular integration framework, builds on the principles of the EIPs (Enterprise Integration Patterns) and DSLs (Domain Specific Language). In this talk we show how integration can become much easier and accessible with Camel. By wiring together EIP patterns, processes and transports, integrating becomes as simple as building routes "lego style.", The wiring is done using the Camel DSL. We will cover some of the most used EIP patterns such as Splitter, Aggregator, Recipient List, Dead Letter Channel, Idempotent Consumer etc. And give pointers about tips and tricks along the way. This talk includes live demos that show how to build integration flows in the four DSLs: plain Java, XML, Groovy and Scala. We will also show you how you can use Eclipse tooling to build routes using a graphical drag'n'drop environment, as well how to gain insights into running Camel applications, such as message tracing.

Keynote: Enterprise Java in 2012 and Beyond

The Java space is facing several disruptive middleware trends. Key factors are the recent Java EE 6 and Java SE 7 platform releases, but also modern web clients, non-relational datastores and in particular cloud computing, all of which have a strong influence on the next generation of Java application frameworks. This keynote presents selected trends and explores their relevance for enterprise application development, taking the most recent Java SE and Java EE developments into account as well. In addition, the Spring Framework will serve as a reference example for an application framework on top of modern deployment platforms. Topics include flexible deployment, web endpoints, caching abstractions, access to alternative datastores, and patterns for concurrent programming.

Presentation: Functional Thinking

Learning the syntax of a new language is easy, but learning to think under a different paradigm is hard. This session helps you transition from a Java writing imperative programmer to a functional programmer, using Java, Clojure and Scala for examples. This session takes common topics from imperative languages and looks at alternative ways of solving those problems in functional languages. As a Java developer, you know how to achieve code-reuse via mechanisms like inheritance and polymorphism. Code reuse is possible in functional languages as well, using high-order functions, composition, and multi-methods. I take a variety of common practices in OOP languages and show the corresponding mechanisms in functional languages. Expect your mind to be bent, but you?ll leave with a much better understanding of both the syntax and semantics of functional languages.

Tutorial: HANDS-ON LAB: Building an end-to-end application using Java EE 6 and NetBeans

The Java EE 6 platform allows you to write enterprise Java applications using much lesser code from its earlier versions. It breaks the "one size fits all" approach with Profiles and extensively improves on the Java EE 5 developer productivity features. Several specifications like CDI, JSF 2, EJB 3.1, JAX-RS, JPA 2, Servlets 3, and Bean Validation make the platform more powerful. It also enables extensibility by embracing open source libraries and frameworks such that they are treated as first class citizens of the platform. NetBeans, Eclipse, and IntelliJ provide extensive tooling for Java EE 6.

This hands-on lab builds a complete end-to-end application using all different technologies of Java EE 6 with NetBeans. You'll learn the tips and tricks to be more effective in your development and deployment cycles. And you'll also learn how to monitor your Java EE 6 applications more effectively. A quick preview of Eclipse and IntelliJ tooling will also be shown.

Please have the following software pre-installed:
JDK 1.6/1.7 (http://www.oracle.com/technetwork/java/javase/downloads/index.html)

Trots att Java och JavaScript båda såg världens ljus 1995 så har det dröjt helt nyligen innan JavaScript nådde sin hajp. Orsaken är förstås prestandan i moderna JavaScript-motorer som V8 och den nya vågen rika webbapplikationer. Men också språket, formellt EcmaScript, har utvecklats. Vi går igenom språkkonstruktioner och designmönster i JavaScript och jämför kontinuerligt med Java för att hitta likheter, skillnader och typiska fallgropar. Hur enhetstestar man JavaScript? Finns privata variabler i JavaScript? Hur paketerar man sin kod? Vilka problem uppstår när mängden JavaScript blir stor?

Quickie: One-liners are your friend: Increasing Productivity with Scala

We believe the success of communication through SMSs, Tweets and Facebook Status messages lies in its conciseness (i.e. 140 characters). Similarly, short and expressive code not only reduces maintenance needs but also increases readibility and ultimately affect the productivity of a programmer. This session is about pragmatic examples of such "one-liners" commonly found in enterprise applications development. In particular, we will exhibit the invocation and transformation of REST services with frameworks like Unfiltered and Akka Futures and show how the REPL(Read Eval Print Loop) command tool can save you a lot of time by programming interactively with one-liners.

Presentation: PaaSing a Java EE Application

A PaaS offering typically facilitates application deployment without the cost and complexity of managing infrastructure, by providing all of the facilities required to build and deliver services. Current Java EE deployment requires the deployer to provision the various dependent services of an application in that container. To support PaaS deployment scenarios, GlassFish is working to provide a simplified application provisioning and deployment interface to users, with the runtime handling the discovery of service dependencies, provisioning services, and associating service references with these services. Some of the metrics (such as CPU, memory, and response times) can be used to monitor system health. These metrics can then be used to determine if the cluster of virtual machines hosting the Java EE container needs to be dynamically expanded or shrunk to accommodate fluctuations in demand. This session details how Java EE containers such as GlassFish can provide such service orchestration and elasticity capabilities.

This session will take an existing Java EE 6 application and walk through the complete life cycle of taking this application from desktop to a PaaS environment. The session will explain the development, testing, and debugging of such an application in the PaaS envinronment.

Presentation: Patterns of Agile Enterprise Architecture

There is widespread acceptance that software development using Agile methods works well. However, there are still areas of software development organisations that view their roles or mandates as incompatible with Agile methods. This talk addresses the legitimate role of an Enterprise Architect and provides concrete recommendations on how Architects can work with Agile development teams to accomplish their objectives. Topics will include concerns about data architecture, addressing the "ilities", and why evolutionary architecture works.

Presentation: Play Framework 2.0

The Play framework has brought high-productivity web development to Java with three innovations that changed the rules on Java EE: Java class and template save-and-reload that just works, a simplified stateless architecture that enables cloud deployment, and superior ease-of-use. Following Play's rapidly-growing popularity, Play 2.0 will be released in early 2012 with innovations that are not just new in the Java world: type safe view templates and HTTP routing, compile-time checking for static resources, and native support for both Java and Scala.

Type safety matters. After dynamically-typed programming languages such as PHP and Ruby set the standard for high-productivity web development, Play built on their advantages and has created a type safe web development framework with extensive compile-time checking. This is essential for applications that will scale to tens of thousands of lines of code, with hundreds of view templates. Meanwhile, Play avoids the architectural-complexity that is promoted by Java EE-based approaches. The result is that Play 2.0 first enables rapid initial application development and then Play 2.0 helps you build big, serious and scalable web applications.

Presentation: Retrospective from the year of DevOps

The way we are developing systems is undergoing a radical change. Starting with the agile movement a few years ago, we are now in a position where organizational walls are falling like domino bricks and people think in new ways to such extent that a paradigm shift is the only suitable description. How can it be possible to have more fun, experiment more, do less boring tasks, while at the same time make business people feel free, happy and innovative - in short - create a more successful company. This talk addresses some of what this is all about and hopefully sends the audience a bit on the way to a full paradigm shift.

Presentation: SQL, NoSQL, NewSQL? What's a developer to do?

The database world is undergoing a major upheaval. NoSQL databases such as MongoDB and Cassandra are emerging as a compelling choice for many applications. They can simplify the persistence of complex data models and offering significantly better scalability and performance. But these databases have a very different and unfamiliar data model and APIs as well as a limited transaction model. Moreover, the relational world is fighting back with so-called NewSQL databases such as VoltDB, which by using a radically different architecture offers high scalability and performance as well as the familiar relational model and ACID transactions. Sounds great but unlike the traditional relational database you can't use JDBC and must partition your data.

In this presentation you will learn about popular NoSQL databases - MongoDB, and Cassandra - as well at VoltDB. We will compare and contrast each database's data model and Java API using NoSQL and NewSQL versions of a use case from the book POJOs in Action. We will learn about the benefits and drawbacks of using NoSQL and NewSQL databases.

Presentation: Tackling Android fragmentation

The number of Android powered devices are sky rocketing. To reach larger audiences, developers want to create applications that are compatible with as many devices as possible. This results in having to cope with different android versions, screen sizes, aspect ratios and pixels densities. The possibilities have become even greater with the introduction of Android 4, Ice cream sandwich. Since Google's latest version of Android is backwards compatible with Honeycomb, developers can potentially adapt their tablet applications to work on the latest phones and reach a larger, and growing user base. An important goal for Android 3 was to make it easier for developers to write applications that can scale across a variety of screen sizes, beyond the facilities already available in the 2.x platform.

The presentation will cover how to use fragments to achieve a high level of code reuse in the UI layer. The presentation will also cover how to use the Android compatibility package to build applications that can be installed, from a single APK, to a wide range of devices including both phones and tablets. A migration path from applications written for phones to tablets, using this package, will also be outlined.

Presentation: The Art of (Java) Benchmarking

People write toy Java benchmarks all the time. Nearly always they "get it wrong" -- wrong in the sense that the code they write doesn't measure what they think it does. Oh, it measures something all right -- just not what they want. This session presents some common benchmarking pitfalls, demonstrating pieces of real, bad (and usually really bad) benchmarks such as the following: SpecJVM98 209_db isn't a DB test; it's a bad string-sort test and indirectly a measure of the size of your TLBs and caches. SpecJAppServer2004 is a test of your DB and network speed, not your JVM. SpecJBB2000 isn't a middleware test; it's a perfect young-gen-only garbage collection test. The session goes through some of the steps any programmer would go through to make a canned program run fast -- that is, it shows you how benchmarks get "spammed." The session is for any programmer who has tried to benchmark anything. It provides specific advice on how to benchmark, stumbling blocks to look out for, and real-world examples of how well-known benchmarks fail to actually measure what they intended to measure.

Come see - I?ll show you), so you get the best language (Lisp) on the best runtime (JVM) -Isn?t Lisp the one with all the parenthesis? Yes. -What?s so compelling about Clojure? It?s fast, expressive, powerful, and allows you to do all sorts of things that other languages won?t let you do. It?s an elegant language. -Why is the entire talk done as question and answer? It?s an homage to a series of books, The Little Lisper and The Little Schemer. Because Lisp?s are simple and homoiconic, this style works nicely for them. Besides, it?s better than 1000 bullets, isn?t it?

Presentation: The Kotlin Programming Language

Kotlin is a new statically typed JVM-targeted programming language developed by JetBrains and intended for industrial use. Kotlin is designed to be fully Java-compatible, and at the same time safer, more concise than Java and way simpler than its main competitor, Scala. Also, IDE support is being developed in parallel with the language itself. Kotlin is under development. Currently, documentation describing the design of the language is available, and an initial beta release of the compiler is planned for the end of 2011. In the presentation, we will give an overview of the language and demonstrate the IDE support capabilities. The features we're planning to cover include: first-class functions (closures), pattern matching, null safety and automatic casts, extension functions, class objects, reified generics and declaration-site variance.

Presentation: Tuning the HotSpot JVM's Garbage Collectors

The HotSpot JVM has been refined and revised with every release of the JDK since the advent of Java in the mid 90ies. Today, Java developers face an abundance of GC algorithms - from plain and simple serial stop-the-world collectors with a single reaper thread to highly parallelized collectors that run several GC threads concurrently with application threads. Each of these collectors can be configured and tuned in various ways in order to control pause times or increase throughput. The number of choices a Java developer has for configuring the JVM:s garbage collection for his application is overwhelming. Hence, garbage collector tuning for the SUN/Oracle JVM is a daunting task. The talk aims to shed light onto the garbage collection strategies in the Sun/Oracle JVM by explaining all algorithms (including Java 7:s Garbage-First collector) and discussing strategies for tuning and configuration of the various collectors.

Presentation: Up and out: Scaling software with Actors

We believe that one should never have to choose between productivity and scalability, which has been the case with traditional approaches to concurrency and distribution. The cause of that has been the wrong tools and the wrong layer of abstraction and Akka is here to change that. Akka is using the Actors together with Software Transactional Memory (STM) to create a unified runtime and programming model for scaling both UP (utilizing multi-core processors) and OUT (utilizing the grid/cloud). With Akka 2.0 this will be taken to a whole new level, and in this presentation we will talk about "Distributed by Design", how it scales from small projects to huge projects, and how we've projected what we've learned during the 1.x series into the 2.x series.

Presentation: Zero Downtime Continuous Deployment of Java Web Applications

Continuous Deployment allows to deploy code in production as soon as it has passed the quality assurance tests. This technique can dramatically reduce the release cycles, giving the company the speed expected in today's world, specially for internet based services. With the right tooling and techniques, a company can create an error free and secure process to automatically deploy its applications in production. Continuous deployment, however, is only viable if you can guarantee zero downtime for your application during the deployment process. With dynamic languages like PHP and Ruby, this is straightforward. Just copy the new files to the deployment folder and voilà! With Java web applications, however, things are not so simple. Although many application servers offer autodeploy features, you'll still have a few seconds of downtime while the server is deploying the application. This presentation will show how to create a continuous deployment process with zero downtime for Java web applications. Using tools like Hudson/Jenkins, REST services and open source application servers, you'll learn through real world examples how to create a secure and error free continuous deployment process for your application. We will also show how to deploy to cloud based servers, like Amazon AWS, what are pitfalls and limitations for these cloud offers and how you can overcome them.
