    Regional Failover and Disaster Recovery in Azure

    by Anne Bougie
    In recent years there have been instances where the Internet is not available across broad geographical regions. One of the benefits of moving to the cloud is being able to utilize geo-redundancy for disaster recovery. Azure has a bewildering array of tools and services available, but the devil is in the details, and using the wrong tool for the job could be, well, disastrous. This session will cover the services and their trade-offs. We will demonstrate a working example of a coordinated solution that gracefully fails over with minimal disruption to the end user.

    Docker for Everyone

    by Brian Hogan
    Docker is an amazing tool, but unless you work with it every day, you're probably left with a ton of questions. What's a container? What's an image? What's the difference between Docker, Machine, Compose, and Swarm? Why the heck should I care? Well, Docker makes it easier than ever to deploy and scale your applications and services. In addition, it lets you simulate your production environment on your local machine without heavy virtual machines. In this talk, we'll explore the basics of Docker, create a custom image for a web application, create a group of containers, and look at how you can put your apps into production on various cloud providers. At the end of the talk, you'll have the knowledge you need to put this to use with your own applications.

    Approaching WebAssembly

    by Dan Callahan
    WebAssembly is a new low-level, high-performance alternative to JavaScript on the Web. As an open standard developed by Mozilla, Google, Microsoft, and Apple, WebAssembly will eventually run everywhere that JavaScript does: in every major Web browser, and in runtimes like Node.js and Electron which are derived from those browsers. After three years of research and experimentation, WebAssembly is finally real. The specification has stabilized, and the first implementation debuted with Firefox 52 on March 7th, and in Chrome shortly thereafter. This talk examines WebAssembly from a practical standpoint, answering what it is, why it was created, how it works, and how you can use it today.

    Building Shiny Web Apps with TypeScript and Angular 2

    by Dustin Ewers
    From humble beginnings, JavaScript has gone from a hastily thrown together language for web pages to a hastily thrown together language that runs everywhere. If you can do it with code, you can probably do it in JavaScript. It's the Swiss Army Knife of programming languages.  Unfortunately, JavaScript wasn't designed for the large scale apps we use it in today. We've had to rely on design patterns, willpower, and luck to mitigate JavaScript's failings. However, there is a better way. TypeScript adds features to JavaScript that make it usable on large projects. Additionally, the bar for web applications gets higher everyday. jQuery was cool ten years ago, but it doesn't cut it for modern web apps. We need something with a little more horsepower. Angular 2 makes it easy to build clean, modular web apps. In this talk, we'll explore TypeScript and Angular 2 and how they can be used together to build large-scale web applications. We will learn how to get started and get up to speed quickly.

    Understanding Async in Javascript

    by Hao Luo
    Javascript traditionally relied on callback functions to handle asynchronous processes. As your Javascript application grows, you would encounter "Callback Hell", which makes your code unreadable and error-prone. There are now several ways to combat callback hell, and make your application development more enjoyable. The presentation will quickly go over shortcomings of callback functions, an overview of ES2015 promises, and generators, and how those two paradigms are related to the new ES2016 feature async/await.

    Tabs Vs. Spaces - The Greatest Battle of Our Time

    by Jason Bock
    Tabs. Spaces. Such simple things, yet the epic wars that have been raged around these characters in developer circles have been tumultuous. Countless hours have been wasted in code reviews debating who is right and wrong. Teams have been torn asunder. Trolling has reached internet-crashing proportions. But the question remains: which one is better? In this session, we'll cut through the hyperbole and emotions and get down to business. We'll see how compilers work with code, and how tests are set up to yield hard facts on performance and memory usage. We'll use this information to make rationale judgements for our coding standards. Come to this session with a sense of humor, and leave with insight into code analysis, automation, and decision making.

    Why You Really Need Azure Functions

    by Jason Lattimer
    Have some code that's maybe not quite a full application that you need to deploy without worrying about the hassle of managing environments? Well look no further than Azure Functions! Yes, you're probably thinking there's already a dozen other ways to host an application that you already know about so why think about another? Azure Functions provide a uniquely flexible platform which allows developers to deploy code in multiple ways using multiple languages while being able to bind directly Azure or HTTP based triggers. If that doesn't sound appealing then at least you could tell everyone you're going serverless, which sounds cool, right? In this session we'll explore scenarios where using Azure Functions could be useful, pros and cons compared to other technologies, and plenty of examples to give you some ideas.

    Speed vs. Speed to Market

    by Jeremy Wagner
    We all agree that performance is important, but in our zeal to be first to market, we don’t realize that performance problems exist until a site is already in production. This talk is intended to arm developers and other technically-inclined professionals with knowledge that will help them be proactive in addressing this difficult problem. In this session, you’ll learn about: - Evoking genuine concern for performance by helping your colleagues identify your site’s target audience, and identify that audience’s capabilities by using data from Akamai’s State of the Internet connectivity report. - How to use this newly-acquired information in concert with automated testing tools to approximate what key performance metrics will be for your users. - Spring into action by automating optimization tasks with Node and gulp, so that you’ll be optimizing as you develop, instead of after the fact. - Some techniques for achieving quick performance wins for troublesome sites already in production, such as resource hints, PostCSS and more.

    The Psychology of Error: Why Smart Teams do Dumb Things

    by Ken Howard
    Why do even the smartest teams make decisions that seem dumb in retrospect? What do you do when the biggest impediment to success is your own brain? Even equipped with the best possible data, a growing body of research reveals just how deeply flawed our perceptions, thinking, and conclusions are and why.  Be careful not to assume that agile methods alone are the solution. What is the Solution? Awareness! By exploring the psychology of error we create the opportunity to overcome many of the pitfalls hindering even the best teams.  We reveal a common condition that lowers individual IQ by 13 points! We show why many teams perform far below the level they think they are. We explore the biases, fallacies, and mental pratfalls common to every one of us rendering even the smartest teams dumb. You’ll come away with an understanding of the very real forces that distort our decisions and concrete tips you can use to mitigate the damage, and avoid these traps altogether.
