Many of you may have an architect title, take on the role of an architect, or even aspire to be an architect, but are you thinking like an architect? Architectural thinking is learning to look at a problem or task from an architect's point of view. In this session we will look at many facets of architectural thinking, including how requirements shape the architecture, component-based thinking, how to make architecture decisions, and what feasibility and vitality means to an architect.

Agenda:

expectations of an architect
technical breadth vs. depth
how requirements shape the architecture
making architecture decisions
component-based thinking

Just as developers use design patterns in software development, architects use well-defined architecture patterns to get a head start on defining the characteristics and shape of the architecture for a system. In this session we will explore some of the more common architecture patterns and use concrete real-world examples to demonstrate how the patterns work. I will also go over the pros and cons of each pattern and discuss how requirements and operational aspects can drive which patterns to use. Using the right architecture pattern for your system is critical, because as we all know, once in place the architecture is very hard to change.

Agenda:

Why use architecture patterns?
Layered Architecture Patten
Event Driven Architecture Pattern
Microkernel Architecture Pattern
Space-based Architecture Pattern

In the past I have presented quite a few fun sessions about software development anti-patterns - things we repeatedly do while developing code that produce negative results. In this session, I will use the same “pattern” as with my other anti-pattern talks and introduce and discuss many of the common software architecture anti-patterns. These are perhaps more significant than the development anti-patterns because they are harder to refactor. Therefore, knowing these anti-patterns ahead of time will save you time, trouble, and perhaps even your job!

Agenda:

Introduction
A detailed look of the most common architecture anti-patterns

Service-Oriented Architecture (SOA) has become an ugly word in the industry. Not only is everyone more confused than ever about what SOA is, but the tooling and products surrounding SOA has made it into a ubiquitous buzzword that has little or no meaning these days. That said, SOA as an architecture pattern is still very much alive and solves many issues within a service-based architecture approach. So what is SOA from an architecture standpoint? In this product-free session we will take a detailed look at SOA from an architecture pattern point of view, understand how abstraction plays a part in SOA, and also understand the implementation aspects of the pattern. At the end of this session we will look at a few service bus considerations, including dealing with single point of failure scenarios, performance bottleneck issues, and service bus roles and responsibilities.

Agenda:

architecture pattern elements
forms of abstraction
pattern implementation (no products!)
service bus considerations

Now that Java is supporting lambda expressions, it's time to hone our skills to make use of them. Lambda expressions can help create concise code, however, it takes more than learning the syntax to put them to good use.

In this presentation we will learn the idiomatic use of lambda expressions, explore the ways in which we can use them to solve common tasks, and look into libraries and APIs that make use of them in Java.

Java 8 brings support for lambda expressions and functional style of programming. With that, the design concepts and the patterns we're used to in Java enjoy a makeover.

Come to this presentation to learn about how the familiar patterns transform and shine in Java 8.

Programming concurrency has turned into a herculean task. I call the traditional approach as the synchronized and suffer model. Fortunately, there are other approaches to concurrency and you can reach out to those directly from your Java code.

In this presentation we will discuss the actor based concurrency and also the software transaction memory. We will then develop examples using AKKA and compare the power of these approaches in contrast to the traditional approach.

It was over 10 years ago that Spring hit the scene and made a big impact in the enterprise Java development ecosystem. Now that Spring 4.2 is available (and Spring 5 on the way), there's a lot of new features and a lot that you may not know about yet.

Whether you're already working with Spring 4 or are anxious to make a move up, there's plenty of new tricks Spring has in store for you. We'll explore them all in this overview of everything that's new in Spring.

In this session, we'll see how to build real Spring applications using Spring Boot. We'll also look under the covers to see what makes Spring Boot tick.

Spring offers a number of configuration options: XML configuration, Java configuration, and Groovy configuration to name a few. To some degree, component-scanning and autowiring help eliminate some explicit configuration. But in general most Spring applications require some essential “bootstrap” configuration to enable key functionality. What's the right way to build Spring applications when there are so many choices?

What if I told you that configuration was optional?

Spring Boot is an exciting new programming model for Spring that makes it extremely easy to create stand-alone, production-ready Spring applications. Rather than writing lots of code to satisfy the needs of a framework, Spring Boot helps you focus your coding efforts on your application. Spring Boot takes an opinionated approach to configuring Spring, making it possible to create Spring applications with little or, in some cases, no Spring configuration at all!

For over 10 years, Spring has been the go-to framework for developing powerful Java server applications. Increasingly, however, modern applications are placing heavier demands on the client side, expecting applications to be available anywhere, anytime, and on any device. In a client-rich world, where does Spring fit it?

In this session, we'll explore Spring's role in modern applications where the client can be on someone's desk or in someone's hands. We'll see how to take advantage of various Spring features and libraries to create a rich and responsive application that can run on a variety of devices.

Some come to Agile assuming it involves less discipline than their traditional methods, but this is a misperception. Today, the need for discipline in software development is greater than it ever was. Agile answers that need, arriving at discipline through the Team. Agile Teams must collaborate to develop strong discipline in both planning and execution.

We'll discuss how teams can obtain Agile discipline to achieve one of our core principles of delivering “working software” frequently. We'll explore some of the key Agile planning and engineering practices like continuous planning, Test-Driven Development, Continuous Integration and Acceptance testing. We'll look at the discipline involved in these practices, their inter-relationship, and the benefits they realize in delivering value to the customer.

The Executable Specification is a result of implementing a set of practices that allow frequent change in software products to ensure that the right product is delivered economically. We'll explore how mature Agile Team's go from User Stories to Executable Specifications by implementing practices that foster collaboration, shared understanding and liberal automation to achieve living documentation that supports the team.

We'll collaboratively walk through a evolving example of how software can be created by utilizing an executable specification to document the the software requirements and confirm it completeness.

Learn how Kanban can lead your team or organization to a sane approach to dealing with too much work while addressing problems quickly in a collaborative environment that drives continuous improvement.

Kanban can be used as a lightweight process to manage the process of a small development team or production support team. It is also used as the engine of a large-scale Agile Enterprises. We will explore the simplicity of Kanban and discipline required to adhere to the basic principles and practices of Kanban. Learn how Kanban can lead your team or organization to a sane approach to dealing with too much work while addressing problems quickly in a collaborative environment that drives continuous improvement.

Although Agile has proven to provide incredible benefits in software development and delivery, it is not foolproof, nor a “Silver Bullet.” Plenty of factors need to be considered before attempting this highly disciplined approach.

Learn from the mistakes other organizations have made and discover which pitfalls to avoid to ensure that your first attempt at applying an Agile approach will be met with a successful outcome. This hour-long web seminar will explore these areas and provide clear steps your team and organization should consider to provide a clear set of tools to maximize the opportunity for best results possible.

In this presentation, we'll see how to use Spring to create, secure, streamline, hyperlink, and consume REST APIs.

In modern applications, there are a diverse array of clients consuming content from the web. Each of these clients has unique capabilities and limitations, therefore demanding presentation of the application to be tailored to each device. As a result, presentation logic is often pushed into the client itself, leaving the application to serve a common data-oriented lightweight API to be consumed by each client.

The sea change in HTML 5 is likely to shift the pendulum away from today's thin-client based server-side web frameworks like Struts 2 and JSF to JavaScript powered next generation rich clients. With strong support for REST, WebSocket and JSON, Java EE 7 is well positioned to adapt to this change.

In this heavily code driven session, we will show you how you can utilize today's most popular JavaScript rich client technologies like AngularJS, Backbone, Knockout and Ember to utilize the core strengths of Java EE using JAX-RS, JSR 356/WebSocket, JSON-P, CDI and Bean Validation.

This session explores how NoSQL solutions like MongoDB, Cassandra, Neo4j, HBase and CouchDB can be used in a Java EE application with or without a JPA centric facade.

Although the primary focus is on EclipseLink NoSQL, we will also cover Hibernate OGM, EasyCassandra, Morphia, etc as well as seeing how NoSQL can be used natively via basic CDI injection.

This session examines the efforts with JSR 356 to support WebSocket in the Java programming model, from its base-level integration in the Java Servlet and Java EE 7 containers to a new, easy-to-use API and tool set that is part of the standard enterprise Java platform.

The family of HTML5 technologies has pushed the pendulum away from thin client technologies and toward ever-more-capable Web clients running on today’s browsers. In particular, WebSocket brings new opportunities for efficient peer-to-peer communication, providing the basis for a new generation of interactive and “live” Web applications. JSR 356 brings these capabilities to server-side Java developers.

The session is a deep dive into JSR 356 including some demos.

Java EE 7 is around the corner and the horizons for Java EE 8 are emerging. This session looks into the key changes the community can expect. The goal of this session is to foster interest and discussion around these changes.

Some of the changes discussed include retiring EJB 2 entity beans and JAX-RPC, greater alignment with CDI, WebSocket/HTML 5 support, a standard API for JSON processing, the next version of JAX-RS, an overhaul of JMS, long-awaited concurrency utilities, batch processing in Java EE and much, much more.

Domain-Driven Design (DDD) promises to simplify enterprise application development and is gradually gaining traction as an alternative to traditional four-tier architectures originally popularized by J2EE. As the name implies, DDD is an architectural approach that strongly focuses on materializing the business domain in software. This session demonstrates first-hand how DDD can be implemented using Java EE via a project named Cargo Tracker.

Part of the Java EE Blue Prints, Cargo Tracker seamlessly maps concepts like bounded contexts, layered architectures, entities, value objects, aggregates, services, repositories and factories to realistic code examples. The Cargo Tracker project also embraces popular practices adopted by the DDD community such as Object Oriented Analysis, Domain Models, Test Driven Development, Agile Refactoring, Continuous Integration, Object Relational Mapping, Dependency Injection and Cross-Cutting Concerns, incorporating these concepts into a realistic Java EE application.

HotSpot promises to do wonders for us by Just-in-Time (JIT) compiling the “right” code for us, but how does it makes those decisions? And, perhaps more importantly, what happens when it's wrong?

In this talk, you'll learn through real code examples just how the JVM decides to compile your code, deoptimize your code, and stop-the-world for a GC.

Early releases of Java performed poorly, but those issues largely disappeared long ago with the introduction of HotSpot. However, much of the performance advice for Java persists through hearsay from those early days.

In this talk, we'll forget the hearsay and take an objective look using benchmarking and profiling tools to find out which optimizations matter today and just as importantly those that don't.

Over the years, Java developers have learned through trial-and-error the best ways to use Java's type system. But certain parts of the type system like wildcard generics and covariant return types are
under used; in-part, because they are not well understood.

Fortunately by going back to the mathematical roots of type systems, we can understand not only wildcard types and covariance, but also why we should prefer composition over inheritance and even how compilers perform some of their optimization magic.

Reactive programming is gaining some good attention recently. If you wonder what this is all about come to this presentation for a practical introduction.

Reactive Programming, what is it, what does it solve, how to use it today?

Spock brings fluency, nice DSL like syntax for writing unit tests. Spock leverages JUnit, but helps makes tests a lot more expressive. Mocking is baked in as well.

In this presentation we will take a look at Spock to unit test both Java and Groovy code. We will build an example, test driven, and along the way explore the features of this powerful tool.

Even taking into account everything that we've learned about operating at “web scale” in the last several years, most applications are designed and implemented to be, as Michael Nygard highlights in his book Release It!, “feature complete” not “production-ready.” Unfortunately, the architectural patterns associated with operating at scale – notably the move toward “micro-services” – introduce an order of magnitude more ways in which our applications can fail. If we do not plan well for failure, we will experience the ultimate failure. But if we do plan well for failure, we have a fighting chance at success.

This talk will take a tour through the James Chiles' book Inviting Disaster: Lessons From the Edge of Technology, and examine what we can learn from engineering fields in the physical world, applying those learnings to the way in which we develop fault tolerant applications.

Even with the recent explosion in alternative languages for the JVM, the vast majority of us are still writing code in “Java the language” in order to put bread on the table. Proper craftsmanship demands that we write the best Java code that we can possibly write. Fortunately we have a guide in Joshua Bloch's Effective Java.

In his foreward to the first edition, Guy Steele writes about the importance of learning three aspects of any language: grammar, vocabulary, and idioms. Unfortunately many programmers stop learning after mastering the first two. Effective Java is your guide to understanding idiomatic Java programming.

Effective Java is organized into 78 standalone “items,” all of which will be impossible to cover in one session. Instead I've chosen a subset of the most important techniques and practices that are commonly missed by today's Java programmers. You'll pick from a menu and decide where we'll head. Regardless of the path we take, you'll leave this session thoroughly equipped to write better Java code tomorrow!

“Docker is an open-source engine that automates the deployment of any application as a lightweight, portable, self-sufficient container that will run virtually anywhere.” Docker creates containers that provide running process with:

an equal slice of CPU
a maximum memory quota
its own process ID (PID) namespace
its own network interface
its own private root filesystem

It does this by leveraging low-level Linux kernel primitives like cgroups and namepaces. The end result is a portable application container that can run anywhere Docker can run, including on VMs, bare-metal servers, OpenStack clusters, public instances, or combinations of the above.

Containers are an excellent way to package your application such that it can run consistently everywhere you want to run it, a fantastic step toward Continuous Delivery. In this session we'll look at how to use Docker to package, deploy, and run Java applications and other services. We'll also compare Docker to another container solution, Warden, which is a key component of the Cloud Foundry PaaS.

We make many assumptions when we develop our applications. Many of these assumptions no longer hold true when we start to build applications for the cloud. Cloud platforms also introduce architectural possibilities that do not exist in traditional deployment settings. This session will examine five architectural patterns that we can apply to our applications in order to prepare them for the unique characteristics of cloud environments.

We'll cover the following patterns:

Microservice
API Gateway
Stateless / Shared-Nothing
Configuration / Service Consumption
Fault Tolerance

Examples will focus on the application of these patterns using Java/Spring and Cloud Foundry-based PaaS platforms, but should be applicable to any language/framework/PaaS platform combination.

Encryption is a powerful tool for privacy. At least that is what we're meant to think.

If you consider encryption to be a black box of magic, you should probably attend this talk.
If you think encryption will protect your secrets, you should probably attend this talk.
If you have (or haven't) been following the news, you should probably attend this talk.

The truth is, encryption can be an effective way of making it harder for people to steal your secrets. But it isn't magical, it isn't fool proof and, depending on how you are using it, may be completely useless. It is a hard topic that we'll only touch the surface on, but there are very few topics that are more crucial for our industry and profession to understand better than encryption. You don't have to understand the math (although that will help), but you do have to understand what it will and won't do for you*.

*and how implementations of it may have been intentionally compromised

Almost every example of an agile project involves a single team and while many successful projects are delivered that way, most enterprise software requires the interaction of several teams. But how do we scale agile beyond a single team? What practices translate and which ones don't? In this talk we'll discuss some of the issues you'll encounter as you move agile beyond a single group and how you can keep multiple stakeholders happy. While it isn't as simple as having a “scrum of scrums” it isn't as hard as replacing every line of COBOL.

Technology changes, it's a fact of life. And while many developers are attracted to the challenge of change, many organizations do a particularly poor job of adapting. We've all worked on projects with, ahem, less than new technologies even though newer approaches would better serve the business. But how do we convince those holding the purse strings to pony up the cash when things are “working” today? At a personal, how do we keep up with the change in our industry?

This talk will explore ways to stay sharp as a software professional. We'll talk about how a technology radar can help you stay marketable (and enjoying your career) and how we can use the same technique to help our companies keep abreast of important changes in the technology landscape. Of course it isn't enough to just be aware, we have to drive change - but how? This talk will consider ways we can influence others and lead change in our organizations.

Back in the day, web developers had to rely on their wits and a plethora of alert statements - to say our toolkit was spartan would be an understatement. But with the increased importance of web front ends and the rise of JavaScript MVC frameworks, a modern web developer toolkit is finally emerging.

We've evolved from text editors to full fledged IDE's with code completion and refactoring tools but our toolchain doesn't end there. With multiple testing libraries, mocking frameworks, test drivers and even code coverage tools, today's web developer gets to walk downhill on a sunny day.

By now, the importance of having a mobile solution is obvious to just about every seat in the organization…but how do develop expertise? How do we work through the inevitable politics and organizational issues? What about the technical questions about hybrid vs. web vs. native?

Before you think about a mid life career change, spend some time listening to what we did in one large company. We may not have had all the right answers, but we learned a few things along the way.

Many software developers point their career towards ascending to the gilded rank of Architect…but what does it mean to actually be one? While many of us labor under false pretense of abject technical decision making, the reality is often very different. You'll code less, spending more time on activities that lack an objective green/red bar. But you'll also an opportunity to impact far more than one project.

In this talk, I'll speak to my own journey. We'll touch on influencing coworkers, the importance of communication and the importance of cup of coffee.

Have you looked at the client side code for a website and noticed all the javacript lives in one file? Does your javascript look like a handful of javascript functions, onClick events and “this”? Having trouble to add new user interaction on your website? Have you heard about some javascript frameworks but not sure of the best steps to get there?

This session is about some practical tips on how to clean up your old javascript. These tips range from some helpful, first small steps to how to add in testing.

You understand the Web. Why do you do REST so wrong?

Doing REST “right” isn't a matter of conformance or purity. It isn't about pleasing hard-to-please Restafarian personalities. It's about understanding that WYBIWYG (What you Build is What You Get). Decisions have consequences. You are free to design and implement whatever you like, but you need to understand the consequences of your choices.

REST, as defined by Roy Fielding's thesis, is a collection of architectural constraints designed to yield certain properties in deployed systems. When you take shortcuts, you simply will not receive all the benefits of loose-coupling, evolvable, flexible, scalable systems. URLs are not enough. HTTP is not enough. To fully embrace the world of REST, you must understand Hypermedia. The good news is that you already do, you've apparently just forgotten.

Here's the thing though. REST is not an endpoint, it is just a beginning. Come to this talk to hear how the story starts. We will take a deep dive into why the Web works, the implications for building Hypermedia-driven REST APIs and start to look at what this means in practice.

The cost of integrating information isn't cheap. Well, at least it isn't if you do it wrong. Chances are, you're doing it wrong.

The single most difficult aspect of data integration is the effort to achieve consensus. It isn't just that we are disagreeable people. It's also that it is a fantasy that there is a “common model” or a “global truth”. Different groups and individuals see the world differently and have different needs from information systems. Language, and therefore what we call things, isn't simply reflective of reality. It plays a constructive and interpretive role.

The problem is that our technologies force us to make choices about world views and pretend that things aren't changing constantly. This yields fragile systems and high impedance to change that cascades through our organizations. This translates to expensive, rigid and difficult to extend failure to give the business what they want.

Our friend Tim Berners-Lee and his Happy W3C Merrymakers have given us a set of technologies to help us solve these problems though. We forget that the Web he designed was not the public Web, but one to solve integration needs for complex organizations like CERN. The HTML bit that we have gotten so excited about is but a small part of the vision. We will introduce RDF and SPARQL as enabling technologies. They do not necessarily replace what you already have, but they do make it possible to share information with people you've never talked to: Collaboration without Coordination.

Webs of documents are fabulous enough. Webs of data will blow your mind.

A table is a fixed structure. A tree is as well. A graph can go on forever and be extended at any time by anyone.

The Web is an unbounded graph. It is our definition of scale. What happens when we start to use it as the basis of sharing information, not just documents. This does not necessarily mean the public Web (although it is certainly appropriate for that as well). It simply means thinking of information as a web of linked entities through discoverable relationships.

Linked data is a way of doing this, but it is also an established project connecting billions of entities from disparate, unrelated sources. How does that even work? What can you do with such a thing? And what does that mean for your organization?

By building on the ideas introduced in the Data Integration talk, we will explore how webs of data built on standards can change everything.

The surge of interest in the REpresentational State Transfer (REST) architectural style, the Semantic Web, and Linked Data has resulted in the development of innovative, flexible, and powerful systems that embrace one or more of these compatible technologies. However, most developers, architects, Information Technology managers, and platform owners have only been exposed to the basics of resource-oriented architectures.

This talk, based upon Brian Sletten's book of the same name, is an attempt to catalog and elucidate several reusable solutions that have been seen in the wild in the now increasingly familiar “patterns” style. These are not turn key implementations, but rather, useful strategies for solving certain problems in the development of modern, resource-oriented systems, both on the public Web and within an organization's firewalls.

NoSQL, not using SQL, has a variety of ways to migrate data. One of my teams wrote their own automated fashion to migrate our database. While doing this we made a conscience decision to remove the ability to “roll back” the database. Why did we think this was a good idea? What are some other alternative approaches to keeping your schema current?

During this talk, I'll discuss solutions with specific examples centered around one popular NoSQL database, MongoDB.

The Cloud Foundry engineering teams have steadily increased their use of the Go programming language (http://golang.org) for building (or rebuilding) components, starting with the Router, and progressing through Loggregator, the “cf” CLI, and more recently the Health Manager 9000.

As a Java-developer-turned-DevOps-junkie focused on helping our customers and community succeed with Cloud Foundry, it's become clear to me that I need to add Go to my knowledge portfolio.

Go is a very interesting language, open-sourced by Google in late-2009, that takes a “less is more” (http://commandcenter.blogspot.de/2012/06/less-is-exponentially-more.html) approach to language design, but that also bakes in a powerful concurrency model.

This talk will introduce Go, delve into its distinctives, and contrast its approach with that of Java (where appropriate). We'll also write a fair amount of Go code along the way. This talk will be of particular interest to Java developers looking to add Go to their toolkits, but will also be of interest to anyone looking to learn a little bit more about Go.

Most of us don't want to go back to the days of malloc and free, but the garbage collector isn't always our friend.

In this presentation, you'll learn about the different garbage collection strategies used in JVMs, how to monitor garbage collection, analyze memory dumps, and why you might want to use one collection strategy instead of another.

Unlike earlier languages, Java had a well-defined threading and memory model from its inception, and over the years additional packages have been added to the standard library to help solve concurrency problems.

Despite all this, Java's memory model still remains poorly understood and
its concurrency libraries under utilized.

In this talk, we'll discuss concurrency in detail starting from the low-level
of the hardware up to the high-level of concurrent collections and Java 7's
new parallel fork join library.

Time is very precious and is often threatened by phone calls, emails, co-workers, bosses, and most of all, yourself. The Pomodoro Technique reigns in unfocused time and gives your work the urgency and the attention it needs, and it's done with a kitchen timer.

In this presentation we discuss how to set up, estimate time, log time, deal with interruptions, and integrate with Agile as a team. We discuss timer software and even some of the great health benefits of the Pomodoro Technique.

Didn't you hear the news? TDD is dead. Yet many developers rely on it for quality code. Come join the zombie apocalypse and learn and understand TDD, what sets it apart from unit testing after the fact, what to do when you need to update code, effective mocking, automatically generating test data and lots of it, leaving code alone and respecting your work, and more

This presentation will cover:

What is TDD?
Benefits of TDD
How to TDD
Mocking
The Great TDD Debate
Opinions of TDD from Industry Leaders
JVM Testing Tools
JVM Testing Languages
Testing Static Calls
Updating Code

This presentation covers the Guava library developed by Google (http://code.google.com/p/guava-libraries/). Guava provides collection extensions to the Java Collection API and, along with this, a cornucopia of time-saving utilities that bring Java as close as possible to some of the more functional and dynamic language competitors like Scala, Ruby, and Clojure.

This presentation focuses on the following topics: how to make Predicates and Functions; how to use new collection constructs that make life easier, including MultiMap, BiMaps, and MultiSets; how to set up and use Guava preconditions; and how to create truly immutable collections, and more. All of this is done with Java.

It seems like all we talk about these days is making our architectures more modular. Buy why? In this session I will discuss the drivers and reasons why it is essential to move towards a level of modularity in our architectures. I will discuss and show real-world use cases of distributed modular architectures (specifically microservices and service-based architecture), and then discuss in detail the core differences between microservices and service-based architecture and when you should consider each. I'll end the talk by discussing the most effective way of migrating to modular distributed architectures.

Agenda:

Drivers for modularity
Modular distributed architectures
Microservices vs. service-based architecture
The move towards modularity

Languages bring a lot beyond syntax, they bring idioms and promote a particular paradigm or even a combination of paradigms. Learning about different languages makes us better designers in languages we work with everyday. That gives us a good incentive to keep an eye on what's out there, what's relatively new and emerging.

In this presentation we will take a look at some relatively new languages, what's special about them, and how we can benefit from them.

Moderns IDEs are great, they let us get our work done, focus on solving problems, provide code prompts, and more. On the flip-side, they hide of lot of details and often do not provide everything to help get our work done. Learning to effectively use the command line, can help us navigate around, write script to automate certain routine tasks, isolate and understand issues, and more.

In this presentation we will lear some ticks and tips we can do on the command line, using some common editors, and general navigation, both for unix-like machines and Windows.

Just like you need to understand execution plans to write efficient SQL, it helps to understand the JVM's execution engine to write efficient Java code.

In this talk, you'll learn how Java's Just-in-Time (JIT) compiler dissects your code, and by doing so you'll learn how to write efficient code more efficiently, but also gain a better understanding of concurrency challenges as well.

One of the key strengths of Groovy is its metaprogramming capabilities. Tools like Grails and Gradle make heavy use of this feature.

In this presentation we will dig into metaprogramming, its strengths, capabilities, and limitations. We will discuss both method injection and method synthesis using live coded examples.

Finally, the Java 8 Date Time API will be in our grasps and now we will celebrate gleefully in the streets! ISO8601 and UTC standards! Immutability! Time to set attention to stun as this presentation will cover all the goods about the new Date/Time API that makes Java programming safe.

We cover in 90 Minutes:
ISO 8601 & UTC
Instants
Periods
Durations
Parsing
Time Zone Manipulations and Updates
Conversion from Old Java Date Times
Whatever else we can cram into the presentation

This will interactive for the most part with few slides. Bring on your questions.

As Tech Leaders, we are presented with problems and work to find a way to solve them, usually through technology. In my opinion this is what makes this industry so much fun. Let's face it - we all love challenges. Sometimes, however, the problems we have to solve are hard - really hard. So how do you go about solving really hard problems? That's what this session is about - Heuristics, the art of problem solving. In this session you will learn how to approach problems and also learn techniques for solving them effectively. So put on your thinking cap and get ready to solve some easy, fun, and hard problems.

Agenda:

Architecting and developing user interfaces used to be relatively easy, pick a server side framework, define a standard monitor resolution and spend your days dealing with browser quirks. But today, the landscape presents us with a plethora of screen sizes and resolutions covering everything from a phone to a tablet to a TV. How does a team embrace this brave new world knowing that the future will introduce even more volatility to the client space?

This talk will walk you through this brave new world. We'll discuss the deluge of devices the typical application must deal with today as well as looking at the plethora of client side rendering technologies. This isn't strictly a front end problem though, we need to reconsider how we've built our server side solutions as well; modern applications rely on RESTful web services delivering data to a diverse set of clients. The development landscape has changed, this talk will prepare you to face these challenges.

Developers are flocking to client side frameworks and, as a result, there are more and more JavaScript libraries attempting to solve the rich internet application problem. In a space where new libraries seem to spring up weekly, what framework should you choose for your next project? While there is consensus around basic ideas like Model View Whatever, there are some strong philosophical differences amongst the various libraries. In this talk, we'll look at the similarities and the differences of some emerging JavaScript libraries discussing why you need to be aware of this rapidly evolving aspect of software development.
