    Introduction to Real-Time Notifications With SignalR

    by Anne Bougie

    As the user experience becomes more important, real-time push notifications are an important tool for web developers to master. Learn how to build real-time server-to-client and client-to-server push services in ASP.NET using SignalR. SignalR makes it incredibly simple to build communication hubs for real-time notifications, peer-to-peer collaboration, and real-time content delivery. SignalR is flexible, extensible and scalable. We will cover setting up a complete MVC5 application using both the Javascript client API and the .NET client. There are several transport protocols available depending on which server and client platforms you are using. We will discuss these options as well as extending, scaling and customizing SignalR.

    A Developer's Guide to Finding Optimal Solutions

    by Barry Stahl

    Solving problems that have more than one possible solution is something every developer will be asked to do over the course of his or her career. Figuring out the best way to utilize the capacity of a device or machine, finding the shortest path between two points, or determining the best way to schedule people or events are all problems where mathematical optimization techniques can be used to quickly and efficiently find solutions.

    In this introduction to mathematical optimization designed specifically for software developers, we will explore some of the foundational techniques for solving these types of problems, and add several of these methods to your toolbox so that you can put them to work for your customers. Since this is a session for developers, we'll keep it in terms that work best for us. That is, we'll go heavy on the code and lighter on the math.

    Business Driven Development

    by Benoy John

    Business Driven Development is a development methodology based on communication between the business customers, the developers, and the testers. BDD encompasses many of the same practices as Specification by Example, Acceptance Test Driven Development (ATDD), Example-Driven Development (EDD), and Story Test-Driven Development (SDD). All these processes aid developers and testers in understanding the customer’s needs prior to implementation and allow customers to be able to converse in their own domain language. This talk will focus on why we need to do BDD, How we can include BDD into our development process, the advantages and challenges in implementing BDD. Examples for this talk will be in .Net/SpecFlow. If you are a Developer, Tester, Business Analyst, Product Owner or a stakeholder in a software development project this talk will show you how you could build products with in-built quality and value and can be extended easily.

    Rethink Frontend Development With Elm

    by Brian Hogan

    Come explore Elm, a functional programming language for making web things. Elm aims to solve some of the same problems that Ember, React, and Angular 2 solve, but in a radically different way. Strong and static typing ensures that data you pass around in your apps really is what you think it is. A simple and tried-and-true architecture makes it easy to understand, and great tooling makes it fun to use.

    In this talk, we'll explore how we use Elm to build our user interface and our code, and we'll take an honest look at where Elm can make a difference for you, and where it falls short. By the end of the talk, you'll know how to get started and have all the resources you need to explore Elm on your own.

    What the Heck is WebAssembly, and do I Have to Learn C Now?

    by Dan Callahan

    Three years ago, Mozilla began experimenting with a low-level subset of JavaScript that supported ahead-of-time compilation and eliminated garbage collection pauses. The experiment worked: Programs written in C and compiled to this intermediate language, called asm.js, could deliver runtime performance within 1.5x of their native C speed. In contrast to Google's Native Client (NaCl / PNaCl) projects, asm.js remained backwards compatible with existing JavaScript engines.

    Clearly, there was room for performance improvement on the Web, and a way to get there without breaking old browsers.

    Last year, Apple, Google, Microsoft, and Mozilla formed a W3C Community Group to collaborate "on a new, portable, size- and load-time-efficient format suitable for compilation to the web." They called it WebAssembly, and it starts landing in browsers this year.

    Suddenly, JS isn't the only game in town: programs will be written in C, compiled to WebAssembly, and run faster than JavaScript ever could. Is this the end? Do we all have to learn C? Come to the talk and find out!

    Creating RESTful Web Services with Grails 3

    by Jennifer Strater

    Integration is a key piece of modern software development. Whether integrating with external vendors or providing APIs for front-end technologies like AngularJS, REST has become the standard. This session will cover the basic principles of REST, how to create RESTful APIs in Grails, and end with a comparison of some of the plugins available.

    Test-Driven Approaches to Documenting RESTful APIs (for Groovy/Java)

    by Jennifer Strater

    Documentation generated from source code is very popular. Solutions such as Swagger are available for many different languages and frameworks. However, limitations of annotation based tools are becoming apparent. An overwhelming number of documentation annotations make for great docs but muddy the source code. Then, something changes and the docs are out of date again.

    That is where test-driven approaches come in.

    Test-driven documentation solutions, such as Spring Rest Docs, generate example snippets for requests and responses from tests ensuring both code coverage and accurate documentation. It can even fail the build when documentation becomes out of date. This session will walk through how to implement test-driven documentation solutions for groovy ecosystem technologies like Spring Boot and Grails. Attendees should have a basic understanding of AsciiDoc and how to construct RESTful APIs in Spring Boot and/or Grails.

    TypeScript In Action

    by Kamran Ayub

    Do you want to learn how to automatically generate strongly-typed Angular services for your Web API? What about Knockout view models that stay synced with your server-side code? In this session, we will walk through a sample application that leverages TypeScript, Angular2, and ASP.NET MVC/Web API. You will learn how TypeScript can help augment your development experience and your existing knowledge as a Javascript developer by adding type safety, OO concepts, and ES6 features to your codebase. If you consider yourself a C# or .NET developer and do Javascript on the side, TypeScript is a great fit for all the paradigms you're used to. If you work in a Linux or Mac world, you’ll still be able to leverage TypeScript with cross-platform tooling. Come and learn something that might help you become more productive and make your applications more robust and less scary to refactor. The speaker recommends watching his previous TypeScript Demystified talk for a grounding in the concepts of TypeScript but it’s not required.

    An Introduction to Semantic 2.0

    by Nate Taylor

    Is CSS and layout a mystery to you? When you read HTML are you able to understand what will be displayed without constantly looking up classes or documentation? If you’re like me, these are problems you run into when doing the view layer of your application. CSS classes become meaningless combinations of letters that don’t really seem to express intent.

    However, there’s a library to help with that. Semantic UI is a framework that aims to create rich UIs “using human-friendly HTML.” Gone are the days of col-md-3. Instead, our HTML will have classes like “three column wide”. But it’s more than that. Semantic UI has a wide variety of elements, collections, and views that can make any application pop, all while following sane patterns.

    Throughout this talk, we’ll look at several key UI components, and talk about the underlying principles of Semantic UI. After leaving the talk, you’ll be bale to install Semantic UI (hint: it’s really simple) and get up and running on your next project.

    Open Source Software for Microsoft Developers

    by Rockford Lhotka

    In today's world it has become virtually impossible to write software without using open source tools, libraries, or frameworks. Even if you avoid "third party" open source components, Microsoft is open sourcing more and more of .NET itself that it is inescapable. So should you be worried? Didn't Steve Ballmer tell us open source was bad and dangerous? Well, there are things you should know about open source in terms of licensing, maintainability, support. Many are things you need to think about when using ANY code you didn't write yourself, whether open source or not. By the end of this session you'll understand where open source does and doesn't differ from traditional proprietary tools, libraries, and frameworks. You might still be worried, but you'll understand WHY you are worried.

    The Definitive Guide to the Flux Pattern for React

    by Vince Bullinger

    React is a JavaScript framework that makes a radical departure from the MV* frameworks that have been inundating the development space for the last several years. With this radically new approach comes a pattern to replace the common paradigm of two-way data-binding MV* frameworks. This pattern is known as "Flux." While React has been gaining steam for a couple of years now, the Flux pattern is still a relative mystery to most of us.

    In this talk, we'll start with a quick recap of React to get everybody up to speed. Then we'll dive into the nuts and bolts of the Flux pattern, investigate some of the more popular Flux frameworks and make sure you walk away fully understanding this enigma.

    Continuous Security

    by Wendy Istvanick

    Worldwide, from government to retail, banking to healthcare, hacks and data breaches are becoming household names. Yet we often ignore many security concerns as we work towards our various delivery deadlines, handling only those that are easy to incorporate. And we generally rely on manual processes to ensure that even these steps are followed.

    Similar to what we are doing with increasing frequency for functional testing, configuration, and deployment, we can integrate some security measures into our pipelines and other processes.

    This talk will go through a few options, using examples for multiple programming languages including C#, Java, and Ruby and highlighting how running them regular could thwart various security threats.
