Distributed version control is all the rage these days, but is it worth it? It has been transformative for the dozens of organizations and thousands of developers that I've mentored on the unique implementation called Git. But don't take my word for it. Discover the joy of a version control system that works for you, not against you, in a hands-on workshop. Bring a Windows, Mac, or Linux laptop and we'll install, set up, use and bend Git into workflows that weren't even possible with the version control systems of yesteryear. Be prepared to rethink how lightweight, fast, and refreshing source code control can be. After completing this workshop you'll be able to do practical work with Git for your day job or weekend OSS hobby

This full day workshop takes you from the ground up with Git. By the end of the day you'll be proficient enough to contribute to an open source project using Git or to leverage inside your corporate as the canonical version control system.

During the all day iOS hands-on tutorial, we will do soup to nuts iOS development. We will start with how to use XCode and build a universal application for iPhone and iPad using a variety of common APIs. We will finish up talking about and demoing how to prepare and deploy to the app store.

The app we build will allow us to experiment with a bunch of APIs including Core Data, Camera, and more.

As a web application developer, most of the focus is on the user stories and producing business value for your company or clients. Increasingly however the world wide web is more like the wild wild web which is an increasingly hostile environment for web applications. It is absolutely necessary for web application teams to have security knowledge, a security model and to leverage proper security tools.

This training workshop on security will provide an overview of the security landscape starting with the OWASP top ten security concerns with current real world examples of each of these attack vectors. The first session will consist of a demonstration and labs using hacker tools to get an understanding of how a hacker thinks. It will include a walk through of the ESAPI toolkit as an example of how to solve a number of these security concerns including hands-on labs using the OWASP example swingset.

The workshop will include several hands on labs from the webgoat project in order to better understand the threats that are ever so common today.

Attendees will come away with the following skills / capabilities: - threat modeling - security audit plan - introduction to Pen testing - key / certificate management - fixing web application security issues

Don't be the weakest link on the web!

Grails represents technology that offers great flexibility and power without the complexity introduced by other Java web application frameworks. Custom tag libraries are a snap. GSP Templates provide a simple mechanism for reusing UI elements. Sitemesh is integrated to help provide a consistent presentation across the entire application. GORM is super powerful ORM. Grails provides simple mechanisms for leveraging the power of Ajax.

This session will cover all of the fundamentals of the framework and will serve as a thorough introduction to developers not familiar with the framework and also include a number of tips and tricks for developers who do have experience with the framework.

For a long while, we've built applications pretty much the same way. Regardless of the frameworks (or even languages and platforms) employed, we've packaged up our web application, deployed it to a server somewhere, and asked our users to point their web browser at it.

But now we're seeing a shift in not only how applications are deployed, but also in how they're consumed. The cost and hassle of setting up dedicated servers is driving more applications into the cloud. Meanwhile, our users are on-the-go more than ever, consuming applications from their mobile devices more often than a traditional desktop browser. And even the desktop user is expecting a more interactive experience than is offered by simple page-based HTML sites.

With this shift comes new programming models and frameworks. It also involves a shift in how we think about our application design. Standing up a simple HTML-based application is no longer good enough.

In this 2-part workshop, you'll get hands-on experience building a simple, yet complete next-generation application that can be deployed in the cloud, consumed from any device, and offers a rich experience for your users.

In an increasingly crowded field of languages, Clojure stands alone. It is a dynamic, functional, high performance dialect of Lisp that runs on both the JVM and CLR. The creator cast aside assumptions from both the Lisp and Java communities to create a remarkable language implementation.

This workshop introduces Clojure to Java developers who might not have seen a Lisp and don’t yet understand why that’s such an advantage. I introduce the language syntax (what little there is of it), cover interoperability with Java, macros, mutlti-methods, and more. I also cover the functional aspects of Clojure, showing its powerful immutable data structures, working with threads and concurrency, and sequences. Beyond just showing syntax, I also show how to build real applications in Clojure, and give you a chance to do the same. Attending this workshop shows enough to pique your interest and show why many of the people who were interested in Java in 1996 are interested in Clojure now.

Domain Specific Languages have two main characteristics, fluency and context. Creating external DSLs has the advantage of good validation. However, we have to struggle with parsers. Internal DSLs offer the benefit of using the language as the host and its compiler as the parser. For a language to be a host, it needs two important characteristics: low-ceremony and metaprogramming.

In this workshop you will learn how to create internal DSLs using Groovy metaprogramming and scripting techniques. We will start with a short warmup of metaprogramming techniques and then dive into creating DSLs.

This presentation seeks to provide a solid introduction to the fundamentals of DDD. Learn why modeling a complex business domain in software is so advantageous to your business and ways in which your team can go about delivering software models to give your business a competitive edge.

The philosophy of domain-driven design (DDD) – first described by Eric Evans in his book [of the same name – is about placing our attention at the heart of the application, focusing on the complexity that is intrinsic to the business domain itself. We also distinguish the core domain (unique to the business) from the supporting sub-domains (typically generic in nature, such as money or time), and place appropriately more of our design efforts on the core.

Domain-driven design consists of a set of patterns for building enterprise applications from the domain model out. In your software career you may well have encountered many of these ideas already, especially if you are a seasoned developer in an OO language. But applying them together will allow you to build systems that genuinely meet the needs of the business.

The premise of domain-driven design is two-fold:

• For most software projects, the primary focus should be on the domain and domain logic; and
• Complex domain designs should be based on a model.

Domain-driven design is not a technology or a methodology. It is a way of thinking and a set of priorities, aimed at accelerating software projects that have to deal with complicated domains.

Note: Laptops are not required - there is no hands-on coding for this workshop.

After 9 years and several significant releases, Spring has gone a long way from challenging the then-current Java standards to becoming the de facto enterprise standard itself. Although the Spring programming model continues to evolve, it still maintains backward compatibility with many of its earlier features and paradigms. Consequently, there's often more than one way to do anything in Spring. How do you know which way is the right way?

In this 2-part workshop, you'll get a hands-on feel for the current best approaches in Spring development. We'll start with a poorly written Spring application and work our way through it, bringing it up to speed with the techniques encouraged by the most recent versions of the Spring Framework and other Spring projects.

In this workshop Oleg will give a short overview of the Enterprise Integration Patterns (EIP) as catalogued in the highly influential book of the same name and Spring Integration (SI) framework. As one of the core developers of the Spring Integration(SI) framework, Oleg will provide a quick introduction of Spring Integration, its API and will demonstrate how SI enables the development of Message and Event based systems. Along the way, you will see how SI builds upon familiar Spring idioms such as interceptors, templates, strategy and other patterns. You will also see how SI maximizes reuse of the integration support available in the Spring Framework core for everything from remoting, JMS/AMQP, data, transactions, task execution and others flattening the learning curve considerably for those already familiar with Spring framework.

After attending this workshop, you will be able to start applying these patterns immediately within your Spring-based applications to solve many of the challenges of enterprise integration. This session consists of 30% slide-ware and 70% live coding.

Git is a version control system you may have been hearing a bit about lately. But simply hearing more about it may not be enough to convince you of its value. Getting hands on experience is what really counts. In this workshop, you'll bring your Windows, Mac or Linux laptop and walk through downloading, installing, and using Git in a collaborative fashion.

The workshop style of this class will allow you to observe and discover the value of this new version control tool first hand. You'll be cloning, creating, commiting, and pushing repositories by the conclusion of this session.

Gradle. Another build tool? Come on! But before you say that, take a look at the one you are already using.

Whether your current tool is Make, Rake, Ant, or Maven, Gradle has a lot to offer. It leverages a strong object model like Maven, but a mutable, not predetermined one. Gradle relies on a directed acyclic graph (DAG) lifecycle like Maven, but one that can be customized. Gradle offers imperative build scripting when you need it (like Ant), but declarative build approaches by default (like Maven). In short, Gradle believes that conventions are great -- as long as they are headed in the same direction you need to go. When you need to customize something in your build, your build tool should facilitate that with a smile, not a slap in the face. And customizations should be in a low-ceremony language like Groovy. Is all this too much to ask?

Gradle has received the attention of major open source efforts and has chalked up significant conversions by the Spring Integration, Hibernate, and Grails projects. What do these technology leaders see in this bold new build tool? They see not only a better way to build Java applications, but an extensive ecosystem of connecting to existing Ant and Maven build files while expanding the horizon of test, CI, and deployment automation in an easy manner. Join us for 90 minutes and let us take you on this same walk of discovery of the most innovative build tool you've ever seen.

This half-day workshop will bring you up to speed on the specifics of the Groovy programming language. We'll touch on most of the major features of the language, from collections and closures to builders, AST transformations, and metaprogramming. Specific examples will cover topics from Groovy itself and will be supported by unit and integration tests and built using Gradle.

Featured topics will include: collections, closures, operator overloading, scripts and classes, unit and integration testing, AST transformations, parsing and building both XML and JSON, and working with SQL. If time is available, other projects from the Groovy ecosystem, like Gradle, Spock, and GPars, will be included.

A minimum comfort level with Java is assumed. Some exposure to Groovy would be helpful but not required.

The net has cracks and crackers are among us. With all the news of security failures, it can be a challenge to know what is FUD and what is really at risk and to what extent. This session isn’t about hacking an application together nor is it about coding a solution. It is about looking at the network and network infrastructure and understanding some of its weaknesses. This workshop is a 50% mix of lecture / discussion and hands on attacking in order to best understand the challenges.

The labs will require the use of: - a virtual machine with BackTrack 5 - a wifi adaptor - and a laptop.

We will have ISO installations of BackTrack 5 for you to install on your VM. It is best if you have this pre-installed, it can be downloaded at http://www.backtrack-linux.org/ . In order to run backtrack, you will want to install this to a virtual machine, if this is new to you, pick up virtualbox or vmware.

The wifi adaptor needed is an Alfa AWUS036H or Alfa AWUS036NHA. You will need 1 of these external adaptors. There are ~ $30 at amazon.

Through the labs we will: - Disassociate wireless traffic - Crack a WEP key - Learn to break through a WPA device - Scan for open ports

When you want to measure fractions of a millimeter, you get a micrometer. When you want to measure centimeters, you get a ruler. When you want to measure kilometers, you might use a laser beam. The abstract task is the same in all cases, but the tools differ significantly based on the size of the measurement.

Likewise, there are some computations that can be done quickly on data structures that fit into memory. Some can't fit into memory, but will fit on the direct-attached disk of a single computer. But when you've got many terabytes or even petabytes of data, you need tooling adapted to the scale of the task. Enter Hadoop.

Hadoop is a widely-used open source framework for storing massive data sets in distributed clusters of computers and efficiently distributing computational tasks around the cluster. Come learn about the Hadoop File System (HDFS), the MapReduce pattern and its implementation, and the broad ecosystem of tools, products, and companies that have grown up around this ground-breaking project.

You may have heard about cloud storage offerings such as Amazon S3, OpenStack or Microsoft Azure. While conceptually similar, these offerings have different apis and behaviour that place the "write once (run|test) anywhere" mantra at risk. The jclouds open source java and clojure library aims to eliminate cloud vendor lock-in, exposing easy to use, portable, and powerful APIs. Bring your laptop, armed with latest revs of Eclipse, git, and maven, and we'll walk through getting you setup to hack jclouds java or clojure BlobStore applications in a collaborative fashion.

During this workshop, you'll discover the value and key gotchas of cloud storage providers first hand. By the end of this session, you'll be writing testable code that creates and manages containers and blobs, and understand how cloud storage can fit into your architecture.

Interested in HTML5? Want a change to play around with the latest and greatest in web app development? This workshop is for you! We'll cover feature detection, web forms, the new HTML elements, take a spin around the canvas, and we'll finish up with offline/local storage and web sockets.

Detecting 101 Before you can take advantage of a new HTML5 feature, you have to make sure a given browser can support it. This section will cover the basics of detection as well as getting the most out of rocking cool libraries like Modernizer. We'll also look at just what to do when a browser doesn't support a feature you're trying to leverage.

New elements Along with a new human type-able doctype, HTML5 introduces several new semantic elements. Recognizing that nearly every website in existence has a header, a footer and some navigation divs, HTML5 gives us a header, a footer and a nav element along with a few others. HTML5 seeks to pave cowpaths, not force the web to bend to its ways...

Canvas One of the most exciting features of HTML5 is the canvas, a space you can use to draw anything from shapes to text to, well, anything! From basic drawing to graphs to full fledged games, canvas opens up a whole new world of possibility, a world sans browser plugins.

Local Storage Web apps are, in many cases, indistinguishable from their thick client brethren, at least if you're not on an airplane. OK, so many planes have wifi, but there are parts of the world that don't have reliable Internet connections! Thanks to local storage and the offline API, all is not lost - you can create a web app that works offline.

Web sockets and web workers Ajax is like so many things in the web world - a simple (but very powerful) hack that isn't defined by a spec. With the advent of the web socket API, we'll finally have a native way to have bi-directional communication with the server. As we create richer and richer clients, we're writing more and more JavaScript. While the JS engines are getting faster and faster, there are cases where it'd be very handy to run scripts in the background. Web workers give us just such an opportunity.

The last decade has seen an explosion in the number of languages targeting the Java runtime. Amongst these, one of the (arguably) strong contenders is JRuby - a 100% Java port of the Ruby language. Ruby aims to make programmers "happy", and with JRuby you can find happiness without having to leave your favorite runtime! JRuby also provides deep integration with Java, allowing you to leverage existing Java libraries while writing code that is succinct, elegant and beautiful.

In this hands-on workshop we will talk about JRuby the language, explore it's syntax and constructs like classes and modules. We will discuss advanced topics like meta-programming and domain specific languages, see how we can write Java applications without writing Java code, and some potential gotchas.

Feel a sense of elation? Already rubbing your hands in glee? Well look no further than this workshop - with lot's of examples and practice code (read: bring a laptop) to work with, you will certainly walk away feeling a sense of euphoria.

Do you want to learn more about Mockito framework directly from the founder? Join the workshop and get up to speed with: - principles of interaction testing - using test spies to drive the design and high quality production code - getting most of the test spy pattern to produce readable and maintainable tests - solutions to typical unit testing challenges with regards to mocking - Mockito features and patterns along with the use cases when they are most useful

See you at the workshop! Please take your laptop so that you can code the exercises in your own, most friendly environment.

The premise of Nicholas Carr's "Does IT Matter?" book was that if everyone uses the same tools, processes, products, etc., is there any competitive advantage to be had from the average IT organization?

NetKernel represents a fundamentally different approach to building systems. It takes what we like about Unix, REST and SOA and mixes it together. It inexplicably changes everything while allowing you to reuse existing code, services and libraries. Not only can it make building the kinds of systems you are building today easier, it does it more efficiently, with less code and a far more scalable runway to allow you to take advantage of the emerging multi-core, multi-CPU hardware that is coming our way.

This workshop will be a deeper dive into Resource-Oriented Computing with NetKernel. We will explore:

• the resource model as it applies to general computing
• the intersection of REST and the resource model
• scaling your software without really trying
• interacting with relational databases
• orchestration around different service types
• logically-layering applications for flexibility
• advanced caching strategies
• leveraging dynamic languages with the resource model
• instant cloud support

It is rare that a technology comes along that is both revolutionary and lets you reuse what you already know. All it takes is a bit of different thinking and a little courage to try something new.

Have you looked into Scala? Scala is a new object-functional JVM language. It is statically typed and type inferred. It is multi-paradigm and supports both object oriented and functional programming. And it happens to be my favorite programming language.

If you are interested in Scala, how you are planning to learn Scala? You probably are going to pick up a book or two and follow through some examples. And hopefully some point down the line you will learn the language, its syntax and if you get excited enough maybe build large applications using it. But what if I tell you that there is a better path to enlightenment in order to learn Scala?

Scala Koans, a set of test cases that will teach you Scala language. The Scala koans will help the audience learn the language, syntax and the structure of the language through test cases. It will also teach the functional programming and object oriented features of the language. Since learning is guided by failing tests it allows developers to think and play with the language while they are learning.

The Web is changing faster than you can imagine and it is going to continue to do so. Webs of Documents are giving way to machine-processable Webs of Information. We no longer care about data containers, we only care about data and how it connects to what we already know.

Perhaps the concepts of the Semantic Web initiative are new to you. Or perhaps you have been hearing for years how great technologies like RDF, SPARQL, SKOS and OWL are and have yet to see anything real come out of it.

Whether you are jazzed or jaded, this workshop will provide you with the understanding of a technological tidal wave that is heading in your direction.

In this workshop, we will:

Explain the Web and Web architecture at a deeper level Apply Web and Semantic Web technologies in the Enterprise and make them work together Integrate structured and unstructured information Create good, long-lived logical names (URIs) for information and services Use the Resource Description Framework (RDF) to integrate documents, services and databases Use popular RDF vocabularies such as Dublin Core, FOAF, DOAP Query RDF and non-RDF datastores with the SPARQL query language Model and Do Inference with the Web Ontology Language (OWL)

Bring your laptops. This is a hands-on workshop.

Solr Recipes provides quick and easy steps for common use cases with Apache Solr. Bite-sized recipes will be presented for data ingestion, textual analysis, client integration, and each of Solr’s features including faceting, more-like-this, spell checking/suggest, and others.

Quick and easy steps for common Apache Solr use cases

• Ingesting recipes: CSV, relational databases, file system, web crawls, API

• Analysis recipes: copyField, character mapping, tokenizing and filtering, configuring for suggest, data exploration

• Faceting recipes: field, date and numeric range, pivot, and query faceting

• Other featured recipes: more like this, spell checking/suggest, grouping, clustering

You're serious about improving the quality of your code base, but with 10,000 lines of code, where do you start and how do you ensure the greatest ROI for the re-work your team members will perform?

Sonar is an open source tool that brings together the best of breed static and dynamic analysis of Java projects. The result is a unified view of problematic areas of your code on a time-line basis, allowing the team to attack the problems with the best ROI, and maintain a more watchful eye for positive and risky trends in the codebase in the future.

This workshop will get you up and running with Sonar on your laptop and analyzing the source code of a project in under 90 minutes.

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.

In this 2-part workshop, we'll dig in with a hands-on exploration of a variety of data stores, including Redis, MongoDB, Neo4j, and traditional RDBMS. In doing so, you'll experience first-hand how Spring Data simplifies working with these data stores.
