Effective Spring
Friday 1:15 PM - Craig Walls
After almost a decade 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?
Watch Video Preview >NoSQL Smackdown 2012
Friday 1:15 PM - Tim Berglund
Alternative databases continue to establish their role in the technology stack of the future—and for many, the technology stack of the present. Making mature engineering decisions about when to adopt new products is not easy, and requires that we learn about them both from an abstract perspective and from a very concrete one as well. If you are going to recommend a NoSQL database for a new project, you're going to have to look at code.
Watch Video Preview >Build Lifecycle Craftsmanship Tools
Friday 1:15 PM - Matthew McCullough
You've heard a bit about Git, Gradle, Jenkins, and Sonar, but are you putting them to use? Are you maximizing what they can offer in terms of standardized project models, faster incremental compiles, automated commit-triggered builds, and rapid source code analysis? In this intense presentation, live demonstrations will be given for all of the latest versions of the aforementioned tools and what they have to offer a highly proficient Java developer.
Watch Video Preview >Groovy, part 1: Collections, closures, and the Groovy JDK
Friday 1:15 PM - Kenneth Kousen
Want to use Groovy but don't have time to read all of Groovy in Action? This talk gives you a whirlwind introduction to its capabilities, from basic data types, Groovy strings, POGOs, collections, Groovy SQL, and the Groovy JDK.
Watch Video Preview >Developing Next-Generation Applications
Friday 3:15 PM - Craig Walls
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.
Watch Video Preview >Cassandra: Radical NoSQL Scalability
Friday 3:15 PM - Tim Berglund
Want to go deep on a popular NoSQL database? Cassandra is a scalable, highly available, column-oriented data store in use at Netflix, Twitter, Reddit, Rackspace, and other web-scale operations. It offers a compelling combination of a rich data model, a robust deployment track record, and a sound architecture, making it a good choice of NoSQL databases to study first.
Watch Video Preview >Sonar Code Metrics Workshop (Bring a Laptop)
Friday 3:15 PM - Matthew McCullough
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.
Watch Video Preview >Groovy, part 2: Builders, metaprogramming, and AST Transformations
Friday 3:15 PM - Kenneth Kousen
Want to use Groovy but don't have time to read all of Groovy in Action? Building on the Groovy 101 talk, this presentation reviews features of Groovy that aren't based on simplifying Java. Topics include building and parsing XML and JSON, using the metaclass to enhance existing classes, and Abstract Syntax Tree Transformations like @Delegate, @Immutable, @Canonical, and more.
Watch Video Preview >Securing the Modern Web with OAuth
Friday 5:00 PM - Craig Walls
In this session, we'll look at OAuth, focusing on OAuth 2, from the perspective of an application that consumes an OAuth-secured API as well as see how to use OAuth to secure your own APIs.
Watch Video Preview >Git Workshop (Bring A Laptop)
Friday 5:00 PM - Matthew McCullough
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.
Watch Video Preview >Connected Data with Neo4j
Friday 5:00 PM - Tim Berglund
Neo4j is an open-source, enterprise-class database with a conventional feature set and a very unconventional data model. Like the databases we're already used to, it offers support for Java, ACID transactions, and a feature-rich query language. But before you get too comfortable, you have to wrap your mind around its most important feature: Neo4j is a graph database, built precisely to store graphs efficiently and traverse them more performantly than relational, document, or key/value databases ever could.
Watch Video Preview >Spring Data
Saturday 9:00 AM - Craig Walls
This session starts with a high-level look at all that the Spring Data project has to offer. Then we'll dive deeper into a few select Spring Data modules, including Spring Data Neo4j, Spring Data MongoDB, Spring Data Redis, Spring Data JPA, and Spring Data JDBC Extensions
Watch Video Preview >JavaScript Libraries You Aren't Using...Yet
Saturday 9:00 AM - Nathaniel Schutta
You're all over jQuery - you write plugins in your sleep - and before that, you were a Prototype ninja. Your team treats JavaScript like a first class citizen, you've even written more tests than Kent Beck. Is that all there is in the land of the JavaScript developer? Believe it or not, the JavaScript party hasn't stopped. What other libraries are out there? What do they offer? This talk will survey the field of modern JavaScript libraries getting you up to speed on what's new. We'll dive in just deep enough to whet your appetite on a wide variety of libraries such as Backbone, Underscore, Zepto and more.
Watch Video Preview >Gradle Workshop (Bring a Laptop)
Saturday 9:00 AM - Matthew McCullough
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?
Watch Video Preview >Understanding Garbage Collection
Saturday 9:00 AM - Douglas Hawkins
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.
Watch Video Preview >Decision Making in Software Teams
Saturday 9:00 AM - Tim Berglund
Alistair Cockburn has described software development as a game in which we choose among three moves: invent, decide, and communicate. Most of our time at No Fluff is spent learning how to be better at inventing. Beyond that, we understand the importance of good communication, and take steps to improve in that capacity. Rarely, however, do we acknowledge the role of decision making in the life of software teams, what can cause it to go wrong, and how to improve it.
Watch Video Preview >Building Social Web Clients
Saturday 11:00 AM - Craig Walls
You see them everywhere: "Like" buttons, "Tweet" buttons, and now there are "+1" buttons. The social networks have extended their reach beyond their own websites and into almost every web site you visit. But did you know that these simple little buttons are just the tip of the iceberg when it comes to adding social features to your website?
Watch Video Preview >Leading Technical Change
Saturday 11:00 AM - Nathaniel Schutta
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?
Watch Video Preview >Code Archaeology
Saturday 11:00 AM - Matt Stine
Feature requests are steadily pouring in, but the team cannot respond to them. They are paralyzed. The codebase on which the company has "bet the business" is simply too hard to change. It's your job to clean up the mess and get things rolling again. Where do you begin? Your first task is to get the lay of the land by applying a family of techniques we'll call "Code Archaeology."
Watch Video Preview >ClojureScript
Saturday 11:00 AM - Tim Berglund
Clojure has recently been gaining attention as one of the most innovative languages of the JVM in current use, and it has mostly found a home on the server. In parallel, JavaScript has ascended to the position of the most important language of the web, and until recently it has lived only on the client. Few observers looked at the world of web development and predicted that these two would get together. Happily for us, they have!
Watch Video Preview >MongoDB: Scaling Web Applications
Saturday 1:30 PM - Ken Sipe
Google “MongoDB is Web Scale” and prepare to laugh your tail off. With such satire, it easy to pass off MongoDB as a passing joke… but that would be a mistake. The humor is in the fact there seems to be no end to those who parrot the MongoDB benefits without a clue. This session is about getting a clue.
Watch Video Preview >Designing for Mobile
Saturday 1:30 PM - Nathaniel Schutta
The word just came down from the VP - you need a mobile app and you need it yesterday. Wait, you've never built a mobile app...it's pretty much the same thing as you've built before just smaller right? Wrong. The mobile experience is different and far less forgiving. How do you design an application for touch? How does that differ from a mouse? Should you build a mobile app or a mobile web site? This talk will get you started on designing for a new, and exciting, platform. Whether that means iPhone, Android, Windows Phone or something else, you need a plan, this talk will help.
Watch Video Preview >Effective Java Reloaded
Saturday 1:30 PM - Matt Stine
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.
Watch Video Preview >Continuous Delivery Pt 1: Deployment Pipelines
Saturday 1:30 PM - Neal Ford
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. This workshop focuses on the Deployment Pipeline concept from Continuous Delivery.
Watch Video Preview >Enterprise Security API library from OWASP
Saturday 3:15 PM - Ken Sipe
When it comes to cross cutting software concerns, we expect to have or build a common framework or utility to solve this problem. This concept is represented well in the Java world with the loj4j framework, which abstracts the concern of logging, where it logs and the management of logging. The one cross cutting software concern which seems for most applications to be piecemeal is that of security. Security concerns include certification generation, SSL, protection from SQL Injection, protection from XSS, user authorization and authentication. Each of these separate concerns tend to have there own standards and libraries and leaves it as an exercise for the development team to cobble together a solution which includes multiple needs.... until now... Enterprise Security API library from OWASP.
Watch Video Preview >The Mobile App Smackdown: Native Apps vs. The Mobile Web
Saturday 3:15 PM - Nathaniel Schutta
Mobile is the next big thing and your company needs to there. But what does there actually entail? Should you build a native app? On which platforms? Do you have the skills for that? What about the web? Can you deliver an awesome experience using nothing but a mobile web browser? This talk will help you navigate these treacherous waters. We'll discuss the pros and cons of the various approaches and give you a framework for choosing.
Watch Video Preview >Resource-Oriented Architectures : REST I
Saturday 3:15 PM - Brian Sletten
The first in a series of talks that are part of an arc covering next-generation information-oriented, flexible, scalable architectures. The ideas presented apply to both external and internal-facing systems.
Watch Video Preview >Continuous Delivery Pt 2: Infrastructure
Saturday 3:15 PM - Neal Ford
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. This workshop focuses on the agile infrastructure required to implement a deployment pipeline and continuous delivery.
Watch Video Preview >Programming with HTML 5
Sunday 9:00 AM - Venkat Subramaniam
Developing a rich user interface for web applications is both exciting and challenging. HTML 5 has closed the gaps and once again brought new vibe into programming the web tier. Come to this session to learn how you can make use of HTML 5 to create stellar applications.
Watch Video Preview >Rock SOLID Software
Sunday 9:00 AM - Matt Stine
Object-oriented programming was formally introduced in the 1970's with the advent of Smalltalk. C++ took it mainstream in the 1980's, and Java carried it to the next level in the 1990's. Unfortunately, if you examine the vast majority of Java codebases, what you'll find is a bunch of C-style structs (a.k.a. JavaBeans) and functions. As these codebases grow, a number of design smells can potentially crop up, which in turn cripple our ability to respond to change. We need SOLID principles that we can apply to keep our software clean and malleable.
Watch Video Preview >Resource-Oriented Architectures : REST II
Sunday 9:00 AM - Brian Sletten
The second in a series of talks that are part of an arc covering next-generation information-oriented, flexible, scalable architectures. The ideas presented apply to both external and internal-facing systems.
Watch Video Preview >4 Practical Uses for Domain Specific Languages
Sunday 9:00 AM - Neal Ford
Domain Specific Langauges seems like a cool idea, but where's the payoff? This talk provides an overview of how to build both internal and external DSLs (including the state of the art tools), stopping along the way to show how this is practical to your day job.
Watch Video Preview >OOP Principles
Sunday 9:00 AM - Ken Sipe
For decades object-oriented programming has been sold (perhaps over sold) as the logical programming paradigm which provides “the way" to software reuse and reductions in the cost of software maintenance as if it comes for free with the simple selection of the an OO language. Even with the renewed interests in functional languages, the majority of development shops are predominately using object-oriented languages such as Java, C#, and Ruby. So most likely you are using an OO language… How is that reuse thing going? Is your organization realizing all the promises? Even as a former Rational Instructor of OOAD and a long time practitioner, I find great value in returning to the basics. This session is a return to object-oriented basics.
Watch Video Preview >Agile Engineering Practices
Sunday 11:00 AM - Neal Ford
Most of the time when people talk about agile software development, they talk about project and planning practices and never mention actual development practices. This talk delves into best development practices for agile projects, covering all of its aspects.
Watch Video Preview >Resource-Oriented Architectures : REST III
Sunday 11:00 AM - Brian Sletten
The third in a series of talks that are part of an arc covering next-generation information-oriented, flexible, scalable architectures. The ideas presented apply to both external and internal-facing systems.
Watch Video Preview >Spock - Unit Test and Prosper
Sunday 11:00 AM - Ken Sipe
Spock is a groovy based testing framework that leverages all the "best practices" of the last several years taking advantage of many of the development experience of the industry. So combine Junit, BDD, RSpec, Groovy and Vulcans... and you get Spock!
This is a significant advancement in the world of testing.
Watch Video Preview >Programming with Actors
Sunday 2:15 PM - Venkat Subramaniam
Actor based concurrency was popularized by languages like Erlang and Scala. This model of programming provides isolated mutability (as opposed to shared mutability) and easy way implement coordinating processes or tasks. Actors can be local to a JVM, or distributed across VMs and machines. In this presentation we will learn how to use Akka Actors to design and implement distributed concurrent Java applications.
Watch Video Preview >Web Security Workshop
Sunday 2:15 PM - Ken Sipe
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.
Watch Video Preview >Emergent Design
Sunday 2:15 PM - Neal Ford
Emergent design is a big topic in the agile architecture and design community. This session covers the theory behind emergent design and shows examples of how you can implement this important concept.
Watch Video Preview >Semantic Web Workshop
Sunday 2:15 PM - Brian Sletten
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.
Watch Video Preview >Taming Shared Mutability with Software Transactional Memory
Sunday 4:00 PM - Venkat Subramaniam
Mutability is something we're quite used to in Java. Sharing is a good thing. However, shared mutability is pure devil's work. If we remove shared mutability, all the problems of concurrent go away. In practice, however, it's hard to completely get rid of shared mutability. This is where STM comes in with managed shared mutable variables. In this presentation we will take an example driven approach to dive deep into STM, look at what it has to offer, explore different implementations, and how we can design concurrent applications without any explicit locks.
Watch Video Preview >Build Your Own Technology Radar
Sunday 4:00 PM - Neal Ford
A Technology Radar is a tool that forces you to organize and think about near term future technology decisions, both for you and your company.
Watch Video Preview >Stop, DevOp, and Roll Out Software
Sunday 4:00 PM - Matt Stine
What is the DevOps movement? It a nutshell, it is the idea that the days of silos are over. Development, QA, and operations can no longer be thought of as separate warring divisons with their own "turfs." Instead, we must focus on the fact that we are all part of a single value stream for the customer. By collaboration and shared expertise, we can find real overlaps between our previously segregated areas of expertise and optimize that value stream.
