Would Chuck Norris ask you to come hear him speak at a conference? No, he wouldn't. He would TELL you that you're coming, and then roundhouse kick you in the face if you gave him any more lip.
“What would Chuck Norris do?” is a philosophy this session will cover in depth. Other topics include: badass vs a-hole, human duck typing, the art of [not] caring, instrumentality, and what your facial hair says about you. You won't learn any new code in this session, but you might unleash a Pandora's box of awesomeness that will change the way you interact with your coworkers forever.
Architecture has lots of difficult problems, many revolving around modularity and granularity. This session delves into many of the hard parts in architecture and makes many of the problems softer.
Architects often look harried and worried because they have no clean, easy decisions: everything is an awful tradeoff. Architecture has lots of difficult problems, which this talk highlights by investigating what makes architecture so hard. At the of core many architectural problems: getting good granularity, which we illustrate via event-driven architectures, teams, components, architectural quantum, and a host of other examples. We also illustrate reuse at the application, department, and enterprise level, and why /reuse/ seems simple but isn't. We also discuss difficult decisions, how to do tradeoff analysis, tools like MECE lists, and how to decouple services to achieve proper granularity. Architecture is full of hard parts; by tracing the common reasons and applying lessons more universally, we can make it softer.
This session describes how architects can identify architectural characteristics from a variety of sources, how to distinguish architectural characteristics from domain requirements, and how to build protection mechanisms around key characteristics. This session also describe a variety of tradeoff analysis techniques for architects, to try to best balance all the competing concerns on software projects.
Architects must translate domain requirements, external constraints, speculative popularity, and a host of other factors to determine the key characteristics of a software system: performance, scale, elasticity, and so on. Yet architects must also analyze the tradeoffs each characteristics entails, arriving at a design that manages to maximize as many beneficial properties as possible. This session describes how architects can identify architectural characteristics from a variety of sources, how to distinguish architectural characteristics from domain requirements, and how to build protection mechanisms around key characteristics. This session also describe a variety of tradeoff analysis techniques for architects, to try to best balance all the competing concerns on software projects.
This session covers basic application and distributed architectural styles, analyzed along several dimensions (type of partitioning, families of architectural characteristics, and so on).
A key building block for burgeoning software architects is understanding and applying software architecture styles and patterns. This session covers basic application and distributed architectural styles, analyzed along several dimensions (type of partitioning, families of architectural characteristics, and so on). It also provides attendees with understanding and criteria to judge the applicability of a problem domain to an architectural style.
Patterns/antipatterns, techniques, engineering practices, and other details showing how to restructure existing architectures and migrate from one architecture style to another.
A common challenge facing many architects today involves restructuring their current architecture or migrating from one architectural style to another. For example, many companies start with monolithic applications for simplicity, but find they must migrate it to another architecture to achieve different architectural characteristics. This session shows patterns/antipatterns, techniques, engineering practices, and other details showing how to make major changes to architectures. This session introduces a new measure, the architectural quantum, as a way of measuring and analyzing coupling and portability within architectures.
This session describes mechanisms to automate architectural governance at application, integration, and enterprise levels
A nagging problem for architects is the ability to enforce the governance policies they create. Yet, outside of architecture review boards or code reviews, how can architects be sure that developers utilize their rules? This session describes mechanisms to automate architectural governance at application, integration, and enterprise levels. By focusing on fitness functions, architects define objective tests, metrics, and other criteria to ensure governance polices stick.
Java is a language in evolution. There are a handful of language changes in Java 9 and 10 plus several JDK changes in 9, 10, 11, and 12. Some of these changes are significant in that they allow us to do things more effectively than before. The difference can be anywhere from reducing code to avoiding errors that come from verbosity. In this presentation we will explore the language changes first. Then we will visit the additions to the JDK. Along the way we will also look at a few things that have been removed from Java as well.
.
We will program with Java quite differently in the future than we do today. The reason is that Java is embracing asynchronous programming like never before. This will have a huge impact on how we create services and web applications. In this presentations we will look at what asynchronous programming is, what continuations are, how they get implemented under the hood, and how we can benefit from them.
.
Java Modules are the future. However, our enterprise applications have legacy code, a lots of it. How in the world do we migrate from the old to the new? What are some of the challenges. In this presentation we will start with an introduction to modules and learn how to create them. Then we will dive into the differences between unnamed modules, automatic modules, and explicit modules. After that we will discuss some key limitations of modules, things that may surprise your developers if they're not aware of. Finally we will discuss how to migrate current applications to use modules.
.
Vue is a new, progressive front end framework. At first glance, Vue might look like Yet Another Javascript Framework, it's time to take a look.
It is designed from the ground up to be incrementally adoptable, and can easily scale between a library and a framework depending on different use cases. It consists of an approachable core library that focuses on the view layer only, and an ecosystem of supporting libraries that helps you tackle complexity in large Single-Page Applications.
In this session we'll start with a look at how VueJS stacks up against the competition. We will explore VueJs from incremental adoption to building a full SPA. We'll the core concepts and capabilities and take a look at the growing ecosystem around it.
You understand the basics: The core vue library, templates, styling and components. You understand the how and why of Vuejs. What's next?
In this session we start with some core best practices for the vue ecosystem. We dive deeper into some capabilites of the core Vue library, as well as branching out into some of the offical add-ons; specifically:
Vutify, the Vue CLI, vue-router, and nuxt.js.
You've got an legacy MV* app. It's hard to maintain, hard to test, and it's a thorn in your side. You're keeping it running but both the code, and your skillset are getting a little old. If a ground-up rewrite is out of the question, you can use Vue to piecemeal refactor and modernize the app with minimal risk and zero downtime.
One of my favorite features of Vue.js is that it is incrementally adoptable, but what does this mean? Ultimately you can take any part of a webpage and turn it into a vue component. Does that piece require some jQuery widget? No problem. The libraries work just fine, side by side.
This session provides a roadmap for taking a legacy app and incrementially turning it into a modern vue masterpiece.
In this example-driven presentation, you'll learn how to leverage Spring Boot to accelerate application development, enabling you to focus coding on logic that drives application requirements with little concern for code that satisfies Spring's needs.
For over a decade, Spring has sought to make enterprise Java development easier. It began by offering a lighter alternative to EJBs, but continued to to address things such as security, working with various sorts of databases, cloud-native applications, and reactive programming. And, along the way, Spring even took steps to make itself easier to use, offering Java-based and automatic component configuration. Even so, there's still a lot of near-boilerplate code required to develop Spring applications.
Enter Spring Boot. Spring Boot's primary purpose is to make Spring easier to work with. It achieves this in three ways:
All together, Spring Boot lets you focus on fulfilling your application's requirements without worrying about writing code that satisfies the needs of a framework.
In this session, you'll learn how to take your Spring Boot skills to the next level, applying the latest features of Spring Boot. Topics may include Spring Boot DevTools, configuration properties and profiles, customizing the Actuator, and crafting your own starters and auto-configuration.
TBD
In this session, we'll explore the Spring Boot Actuator, a runtime component of Spring Boot that lets you peer inside a running application and, in some cases, even tweak configuration on the fly. We'll look at many of the Actuator's endpoints, learn how to customize and even create new endpoints, and see how to expose Actuator metrics to several popular instrumentation and monitoring systems.
Spring Boot makes developing applications with Spring easy work by offering auto-configuration for many common application scenarios. And with Spring Boot's starter dependencies, even an application's build file can be easily managed. But Spring Boot's powers don't end when the application is deployed. That's where the real fun begins.
You have some modular code with a REST API. You are on your way to Microservices. Next, you package it in a container image that others can run. Simple. Now what? Your service needs to log information, needs to scale and load balance between its clones. Your service needs environment and metadata way outside its context. What about where the service will run? Who starts it? What monitors its health? What about antifragility? Updates? Networking? Oh my.
Don't get flustered. We will explore how Kubernetes simplifies the complexity of distributed computing.
This session will help you understand the terms, architecture and the mechanics of the Kubernetes tools. You will understand how to target your applications to a seemingly complex distributed compute platform.
Prerequisite: If you are unfamiliar with Kubernetes be sure to attend: Kubernetes Koncepts (1 of 2)
Aha moments with apps in containers can be quite liberating. The mobile space is saturated with “there's an app for that”. For us, we now expect “there's a container for that”. “Write once, run anywhere” (WORA) has changed to “Package once, run anywhere” (PORA). The growing community of containers is riding up the hype curve. We will look at many ways to assemble pods using architecture patterns you already know.
Your software package delivery and installation is no longer an rpm, deb, dmg, jar, war, native executable or a run script, it is simply an image that has a common run container command.
During the presentation, we will explore some examples on Katacoda.

At the 2009 Agile conference, J.B.Rainsberger declared “Integration tests are a scam”. I agree. Come see some compelling reasons why consumer-driven contract testing is a much better approach. Particularly for microservices.
We will explore different testing techniques on Kubernetes, including an important one called “Consumer-Driven Contracts”.
After a brief overview of the concepts a live demonstration will show you how to:
Based on the book with the same title as this talk, this presentation will explore the modern features of JavaScript that make this a pleasant language to use. Come to this presentation to get a quick jumpstart on the elegant capabilities from passing arguments, to creating iterators, to destructring, and working with classes using ES 6 and beyond.
.
JavaScript modules are highly powerful but an be confusing with the number of options available to explore and import. In this presentation we will take a through look at what modules are, how to export from a module, how to import, and the dos and don'ts. This will help you get comfortable with modules as you develop applications with JavaScript libraries/frameworks, like Angular, React, Vue, etc.
.
Some developers simply hate type inference. And then there others who love it. Neither one of them is entirely right. In Java we have been making extensive use of type inference for several years without realizing it. The introduction of “var” in Java 10 has stirred up some surprising debate. In this presentation we will step back and review type inference in Java. Then we will dive deep into type inference in Java 10 and 11. We will wrap up the presentation will good recommendations on when to use type inference and when to avoid it.
.
Functional style of programming was introduced in Java 8. If you are like the speaker, who spent decades on imperative style, then the transition to functional style can be intimidating. In this presentation, we will learn about the fundamentals of programming in functional style, the set of tools that we can reach into to solve problems as a series of state transformation. We will learn the how but also the benefits along the way as well.
.
This is the droid you are looking for. Within this droid are hundreds of rules designed to review your code for defects, hotspots and security weaknesses. Consider the resulting analysis as humble feedback from a personal advisor. The rules come from your community of peers, all designed to save your butt.
We will explore techniques on how to add these checks to your IDE, your build scripts and your build pipelines.
Too much chatter in your pull requests? See how the analysis tools teach best practices, without ego or criticism, to a spectrum of developers. As a leader see how to develop an effective code quality intern program around this technique. We will also see some techniques to use Kubernetes to obtain reports and dashboards right on your local machine and from your continuous integration pipeline.
Prerequisite: If you are unfamiliar with Kubernetes be sure to attend: Kubernetes Koncepts.
From operating system on bare metal, to virtual machines on hypervisors, to containers orchestration platforms. How we run our code and bundle our applications continues to evolve. Serverless computing continuous our evolutionary path for our architectures.
Kubernetes provides an ideal, vendor-agnostic platform for serverless computing. Serverless promises to developers that we can worry less about the cluster and focus more on their logic. Based on your Kubernetes knowledge we will discover the various contributors of serverless frameworks on Kubernetes. Specifically, we will unpack how two open source serverless frameworks, Kubeless and OpenFaaS, leverage Kubernetes to achieve their promises. We will explore how Knative is helping the serverless providers evolve to the next levels sophistication.
Kubernetes out of the box is a strong platform for running and coordinating large collections of services, containers, and applications. As is, Kubernetes is powerful for many solutions.
Remember Underdog? He was a mild-mannered dog, but when stress and conflict were introduced to the plot he took a magic pill, he became a superhero. Istio is a superhero for Kubernetes.
Istio is an open, platform-independent service mesh that manages communications between services in a transparent way. With a distributed architecture many things can fail, slow down and become less secure. Istio provides solutions to those stresses in our plot toward this architecture style:
• Traffic management
• Observability
• Policy enforcement
• Service identity and security
We will explore these benefits with Istio through some working examples on Kubernetes. The key point is this meshing solution allows your Java code to be less coupled to the inherent weaknesses of a distributed platform.
Explore another learning medium to add to your toolbox: Katacoda.
This is a 90-minute mini-workshop where you learn to be an author on Katacoda. Bring your favorite laptop with just a browser and a text editor.
Have a Github account and bring your laptop. Let's learn together.
We are continuously learning and keeping up with the changing landscapes and ecosystems in software engineering. Some technologies are difficult to learn or may take too much time for us to set up just to get to the key points of each technology. One of the reasons why you might be here at NFJS is to do exactly that – too learn. Great!
There are many mediums we use to learn and we often combine them for different perspectives. Books, how-to articles, GitHub readmes, blog entries, recorded talks on YouTube, and online courses. All these help us sort through the new concepts. I'm sure you have your favorites.
Katacoda is becoming a compelling platform for learning and teaching concepts. You can also author your own topics for public communities or private teams. Katacoda offers a platform that hosts live server command lines in your browser with a split screen for course material broken into easy to follow steps.
These days, you can’t swing a dry erase marker without hitting someone talking about microservices. Developers are studying Eric Evan’s prescient book Domain Driven Design. Teams are refactoring monolithic apps, looking for bounded contexts and defining a ubiquitous language. And while there have been countless articles, videos, and talks to help you convert to microservices, few have spent any appreciable time asking if a given application should be a microservice. In this talk, I will show you a set of factors you can apply to help you decide if something deserves to be a microservice or not. We’ll also look at what we need to do to maintain a healthy micro(services)biome.
There are many good reasons to use a microservices architecture. But there are no free lunches. The positives of microservices come with added complexity. Teams should happily take on that complexity…provided the application in question benefits from the upside of microservices. This talk will cut through the hype to help you make the right choice for your unique situation.
Every organization has at least a phalanx or two in the “Cloud” and it is, understandably changing the way we architect our systems. But your application portfolio is full of “heritage” systems that hail from the time before everything was as a service. Not all of those applications will make it to the valley beyond, how do you grapple with your legacy portfolio? This talk will explore the strategies, tools and techniques you can apply as you evolve towards a cloud native future.
In this talk, you will learn:
Rich Hickey once said programmers know the benefits of everything and the trade offs of nothing…an approach that can lead a project down a path of frustrated developers and unhappy customers. As architects though, we must consider the trade offs of every new library, language, pattern or approach and quickly make decisions often with incomplete information. How should we think about the inevitable technology choices we have to make on a project? How do we balance competing agendas? How do we keep our team happy and excited without chasing every new thing that someone finds on the inner webs?
As architects it is our responsibility to effectively guide our teams on the technology journey. In this talk I will outline the importance of trade offs, how we can analyze new technologies and how we can effectively capture the inevitable architectural decisions we will make. I will also explore the value of fitness functions as a way of ensuring the decisions we make are actually reflected in the code base.
If you’ve spent any amount of time in the software field, you’ve undoubtably found yourself in a (potentially heated) discussion about the merits of one technology, language or framework versus another. And while you may have enjoyed the technical debate, as software professionals, we owe it to our customers (as well as our future selves) to make good decisions when it comes to picking one technology over another.
In this talk, I will explore what criteria we should consider when comparing technologies, how we can avoid burning platforms as well as what to do when we’ve reached a dead end. We will also apply these techniques to a current technology or two.
Development teams often focus on getting code to production losing site of what comes after the design and build phase. But we must consider the full life cycle of our systems from inception to deployment through to sunset, a discipline many companies refer to as site reliability engineering.
While your organization may or may not have an SRE team, you have someone playing that role and we can all benefit from looking at the principles and practices that we can bring to bear on our projects. In this talk, I will introduce the concepts of SRE and how you can adopt these ideas on your applications.
By now I bet your company has hundreds, maybe thousands of services, heck you might even consider some of them micro is stature! And while many organizations have plowed headlong down this particular architectural path, your spidey sense might be tingling…how do we keep this ecosystem healthy?
In this talk, I will go beyond the buzzwords into the nitty gritty of actually succeeding with a service based architecture. We will cover the principles and practices that will make sure your systems are stable and resilient while allowing you to get a decent night's sleep!
Angular 7 is a big jump for the entire platform, but what does it mean for you? (We'll also cover what's new in Angular 8!)
In this session we’ll explore the things you couldn’t do before by diving into changes in the core framework, Angular Material, and the CLI. We’ll discuss other improvements to the framework and why they might matter to you. We’ll upgrade an Angular 6 application and add some new features to it. And if you’ve stepped away from Angular for a while, you might be surprised at how easy it is to pick it back up.
Microservices have helped us break apart back end services, but large front ends often remain problematic monoliths.
In this session you’ll learn how to apply the same concepts to large front-end applications, slicing them into end-to-end verticals. These verticals can then be owned by different teams and even written in different frameworks. Can Angular, React, and Vue all live together in harmony? How about AngularJS and Angular2+? With micro frontends, the answer is yes!
Git. It can be intimidating if you're accustomed to other kinds of source control management. Even if you're already using it and comfortable with the basics, situations can arise where you wish you understood it better. Developers often just want to write code and tell everyone else to take a hike, but the reality is that most of us work on teams where the feature-based code we write must be integrated, tested, and ultimately released.
This session will cover the most critical git concepts, basic and advanced, in a completely visualized way. At the same time, you’ll pick up git terminal commands to help you understand (or even eliminate) a git GUI you already use. Go beyond the basics to learn how to get yourself out of a git pickle, practical release management strategies, and more.
On the NFJS tour, there are questions that seem to come up again and again. One common example is “How do we determine which new tools and technologies we should focus our energy on learning?” another is “How do we stop management from forcing us to cut corners on every release so we can create better and more maintainable code?” which, after awhile becomes “How can we best convince management we need to rewrite the business application?”
There is a single metaanswer to all these questions and many others.
It begins with the understanding that what we as engineers value, and what the business values are often very different (even if the ultimate goals are the same) By being able to understand these different perspectives it's possible to begin to frame our arguments around the needs and the wants of the business. This alone will make any engineer significantly more effective.
This session picks up from where “Stop writing code and start solving problems” stops discussing what is value, how do we align the values of the business with the needs and values of the engineer.
In this example-driven presentation, we'll look at Spring Data REST, an extension to Spring Data that exposes your data repositories as a RESTful API, complete with hypermedia links. We'll start with essential Spring Data REST, but then go beyond the basics to see how to customize the resulting API to be more than just CRUD operations over HTTP.
Spring Data is a brilliant extension to the Spring Framework that makes simple work of exposing a database–any kind of database–via repositories. But as is often the case, your application's data doesn't usually stay within the application. It is consumed by external applications or from a Javascript client in the web browser. That means, we'll need to build a RESTful API around those repositories.
In this session, we'll explore Spring Security and OAuth2, including building an OAuth2 authorization server, fronting an API with a resource server, and verifying an OAuth2 access token's claims to ensure that the client is allowed to access the resource they are asking for.
Securing REST APIs presents some unique challenges as compared to securing a typical web application. The client of any REST endpoint may not even be a user in the traditional sense, but is more likely to be another application or a browser-based Javascript client. How can you ensure that the clients of your REST API are allowed to access the resources they are asking for?
OAuth2 offers a means by which a client application can request authorization to access a resource and be given an access token that must be presenting when making HTTP requests. This involves creating an authorization server that issues tokens and defining a resource server which acts as a wall around an API that verifies the presented access token's claims before allowing the request to proceed.
Spring Security has historically supported OAuth2 as part of a separate project called Spring Security for OAuth. But gradually, Spring's OAuth2 support is moving into the main Spring Security project.
The way we communicate with our applications is an ever-evolving experience. Punch cards gave way to keyboards. Typing on keyboards was then supplemented by pointing and clicking with a mouse. And touch screens on our phones, tablets, and computers are now a common means of communicating with applications.
These all lack one thing, however: They aren’t natural.
As humans, we often communicate with each other through speech. If you were to walk up to another human and start tapping them, you’d likely be tapped (or punched) in response. But when we talk to our applications, we communicate on the machine’s terms, with keyboards, mice, and touch screens. Even though we may use these same devices to communicate with other humans, it’s really the machine we are communicating with—and those machines relay what we type, click, and tap to another human using a similar device.
Voice user-interfaces (Voice UIs) enable us to communicate with our application in a human way. They give our applications the means to communicate to us on our terms, using voice. With a voice UI, we can converse with our applications in much the same way we might talk with our friends.
Voice UIs are truly the next logical step in the evolution of human-computer interaction. And this evolutionary step is long overdue. For as long as most of us can remember, science fiction has promised us the ability to talk to our computers. The robot from Lost in Space, the Enterprise computer on Star Trek, Iron Man’s Jarvis, and HAL 9000 (okay, maybe a bad example) are just a few well-recognized examples of science fiction promising a future where humans and computers would talk to each other.
Our computers are far more powerful today than the writers of science fiction would have imagined. And the tablet that Captain Picard used in his ready room on Star Trek: The Next Generation is now available with the iPad and other tablet devices. But only recently have voice assistants such as Alexa and Google Assistant given us the talking computer promised to us by science-fiction.
In this example-driven session, we'll explore the Alexa Skills Kit (ASK) and see how to develop skills for Amazon's Alexa. You'll learn how to use the ASK CLI to jumpstart skill development and how to create conversational applications in NodeJS.
Serverless is a big topic these days. More specifically, Function as a Service (FaaS) enables small-scale functions deployed in the cloud to be enabled only as needed. Compared to Platform as a Service (PaaS) services which are “always on” and require explicit scaling, FaaS services wake up when needed and are scaled by the platform automatically.
Imagine a service that only gets invoked one per hour. In PaaS, that service is always running and ready to handle requests, consuming processor resources and ultimately costing more to be ready at a moment's notice. In contrast, FaaS services awaken quickly upon invocation and go away when finished, conserving resources and cost.
In this example-driven session, we'll see how to create and deploy Function as a Service (FaaS) services with Spring and Spring Boot.
An overview of various popular streaming technologies on the JVM: Kafka Streams, Apache Storm, Spark Streaming, Apache Beam. Discuss “the bill of rights” of what to expect of all streaming libraries and frameworks, security, failover, exactly once processing.
Streaming is now an essential part of our life. We have cheaper drives, faster networks, and more memory. We can haul tons of data, but we need to process that data, manipulate and enrich. To do so we need some sort of streaming solution. Let's look at the most common ones and expose the differences and similarities between frameworks so you, the attendee, can make a better decision.
Kafka is more than just a messaging queue with storage. It goes beyond that and with technology from Confluent open source it has become a full-fledged data ETL and data streaming ecosystem.
When we utter the words, Kafka, it is no longer just one component but can be an entire data pipeline ecosystem to transform and enrich data from source to sink. It offers different ways to handle that data as well. In this presentation, we define:
We then discuss KSQLDB. A SQL layer built upon Kafka Streams that provides a simple query language to perform streaming operations
Spark has a machine learning aspect to it and it's called Spark MLLib. We discuss an intro into machine learning, some models, then apply some of those common machine learning models.
You may also already know what Spark is, if not, well, we will either introduce it again or remind you. We will go over a quick introduction to its purpose. Then we will go all Machine Learning on it. We will have a discussion of the purpose of data science, what the rigors are with data science and then apply this data into Spark MLLib. We will discuss the various models and then apply various data into Spark in order to achieve some insight into the data you have and have currently been aggregating.
For those still grappling with Generics. This will be an attempt to clear the air about generics. What are wildcards? What is extends
? What is super
? What is covariance? What is contravariance? What is invariance? What is erasure? Why and when do I need this?
Generics or parameterized type is one of the more pain items in any statically typed language on the JVM. This presentation is set to overcome some of these hurdles and understand some of these confusing terms. We will cover the following:
Creating code is easy, creating good code takes a lot of time, effort, discipline, and commitment. The code we create are truly the manifestations of our designs. Creating a lightweight design can help make the code more extensible and reusable.
In this presentation we will take an example oriented approach to look at some core design principles that can help us create better design and more maintainable code.
For those programmers aspiring to be polyglot, there's a virtual machine that's all polyglot. In this presentation you can learn about GraalVM, what it's for, the benefits it offers, and where you may use it.
.
Many developers aspire to become architects. Some of us serve currently as architects while the rest of us may hope to become one some day. We all have worked with architects, some good, and some that could be better. What are the traits of a good architect? What are the skills and qualities we should pick to become a very good one?
Come to this presentation to learn about things that can make that journey to be a successful architect a pleasant one.
We all have seen our share of bad code and some really good code as well. What are some of the common anti patterns that seem to be recurring over and over in code that sucks? By learning about these code smells and avoiding them, we can greatly help make our code better.
Come to this talk to learn about some common code smell and to share your experiences as well.
In Part 1, you learned the core principles of influence and persuasion. How to we take this back to the office and apply what we've learned?
We dive deep in to specific strategies to get both the team and the business on board with your ideas and solutions. We cover several realworld patterns you can follow to be more effective and more persuasive. Part 1 was conceptual, part 2 is practical.
By the end of this conference you will have learned many new tools and technologies. The easy part is done, now for the hard part: getting the rest of the teamand managementon board with the new ideas. Easier said than done.
Whether you want to effect culture change in your organization, lead the transition toward a new technology, or are simply asking for better tools; you must first understand that having a “good idea” is just the beginning. How can you dramatically increase your odds of success?
You will learn 12 concrete strategies to build consensus within your team as well as 6 technique to dramatically increase the odds that the other person will say “Yes” to your requests.
As a professional mentalist, Michael has been a student of psychology, human behavior and the principles of influence for nearly two decades. There are universal principles of influence that neccessary to both understand and leverage if you want to be more effective leader of change in your organization.
In this session we discuss strategies for getting your team on board as well as when/how to approach management within the department and also higherup in the organization.
Many new features have been added between the last Long Term Support release in Java 8 and the current one in Java 11. This talk will summarize many of those capabilities, from the Jigsaw implementation of JPMS to unmodifiable collections to local variable type inference and more. In addition to the basic code changes, the new six-month release schedule and associated licensing issues will be reviewed.
If, as anticipated, Java 12 is released in March and Java 13 in September, new features from those versions will also be included, even though they will break the joke in the title of this talk.
Learn the basic syntax and semantics for the Kotlin programming language. Kotlin is an alternative JVM language that provides null safety, static typing, and powerful IDE support. This talk will emphasize the relationships between Kotlin and Java, highlighting the differences in types, functional programming, collections, and more.
Demonstrations will include:
and much more.
Good discussions are supposed to diverge from their intended path. Free association is a feature, not a bug, and helps you see new connections between ideas. Without structure, however, it can be difficult to add context to new ideas and understand how they relate to more immediate problems. This talk discusses the technique of mental bookmarks – how to remember where you were when a discussion diverged. In addition to giving you a reputation for having an amazing memory, the skill also helps with personal awareness in general.
To give the technique context, we'll look at the fractal nature of success – the way we tend to see our current environment in relative terms, always comparing ourselves to those slightly more successful and slightly less successful.
Gradle is the build tool of choice in the open source world, and rapidly becoming the standard in industry as well. Anyone who works with Gradle on a Java project knows the basics of the Java plugin and how to write simple tasks in Groovy. Gradle can do much more, however. This talk will demonstrate how to write your own custom task classes and how to create Gradle plugins from them. Other Gradle features will be demonstrated as well, including file manipulation, incremental builds, generating the Grade wrapper, and resolving conflicts in dependencies.
Gradle Inc also provides a free build scan capability to analyze build files. This too will be demonstrated, as well as profiling your build, determining dependencies, and more.
It happens to us all; there are simply days where it seems impossible to get anything done. This session focuses on techniques and tips to get into the zone, stay in the zone and to protect your productivity, even in disruptive environments.
Rather than focusing on any one productivity methodology (e.g. GTD) This talk analyzes the internal and external factors that affect our productivity and offers broader strategies to get back on track.
Micronaut is a modern, JVM-based, full-stack framework for building modular, easily testable microservice applications.
In this session we'll dive deep into Micronaut, it's strengths, capabilities and best practices when building & testing services, functions and reactive apps.
One of the biggest impediments to overall developer productivity and the overall success of the software organization is inefficient processes. Without the right tooling to get to the root of the problem, debugging build and test failures is incredibly frustrating and leads to delays in shipping software.
In this workshop, you’ll work through examples using Maven, Gradle, and Gradle Enterprise on our real data and that of some popular open source projects. You'll learn how to measure build speed and reliability, which metrics are important, how to apply these analyses to your own builds, and how to use build caching to make those builds dramatically faster enabling your team to achieve better developer productivity.
