    Big Data or Big Hype - Analytics from the Developer Perspective

    by Aaron Erickson

    Unless you've been hiding under a rock, you have likely read an article, seen a talk, or read some noxious vendor's brochure hailing the coming "Big Data Revolution". The hype has become so thick that anything that involves a database is being rebranded "Big Data" in the same way that anything that involves the Internet has been rebranded "Cloud".

    In this talk, we are going to separate the cool stuff from the malarkey. We will cover:

    • Big Data and Analytics - Why it Matters
    • What is a Data Scientist? - How are they different?
    • What kind of problems are solved using Analytics?
    • What are the boundaries? What kinds of things should not be called Analytics?
    • What technologies are used? Do they involve functional programming? Hint: It isn't just trendy Hadoop stuff...
    • Real world examples from recent projects

    By the end of this talk, you should be both:

    • excited about analytics - what it can really do for you and your clients
    • prepared to fight the battle between the hucksters who are out there rebranding anything that remotely involves a database as big data - and the real thing that can really drive business value

    Windows Store Tips & Tricks

    by Adam Grocholski

    Congratulations! You made it! The endless cups of coffee, the countless late nights, the lines and lines and lines of code have put brought you to this moment. You're ready to submit your app to the Windows 8 store. You're ready to hit submit. Wait! Stop! Before you click that button, it might be a good idea to make sure you understand the Windows Store certification process to make sure you don't encounter any publication delays due to certification failures that could have been easily avoided. In this session, you'll learn more about the end-to-end process to publish an app to the Store, including monetization options, submission flow and best practices, and certification tips and tricks. Even if you haven't started creating Windows Store applications yet, this session will serve as a good foundation to help you start your journey, and it will help you avoid many of the pitfalls that many first time developers run into.

    9 Tips for a clean BackboneJS App

    by Adam Terlson

    This presentation seeks to eliminate that spaghettified, unmaintainable, untestable mess that JavaScript is so famous for producing and turn it into something beautiful. Developed after working on large teams with devs unfamiliar with JavaScript (not to mention Backbone) and yet tasked to create with it, I will walk through the 9 tips that I've found in practice will make your BackboneJS implementation easily maintained, easier to read, run better, and will allow you to effortlessly write those ever-so-important unit tests. Heavy on code samples, best practices, anti patterns, gotchyas, and random insights, this presentation is meant to serve as a reference point for creating a beautiful Backbone implementation for apps of any size and reduce the learning curve of BackboneJS. Prior experience working with Backbone is recommended, but not strictly necessary.

    Workflow Manager and Service Bus

    by Andreas Erben

    Service Bus has been known for several years as one of the capabilities only available in Azure. There was also no complete engine to run persistent workflows for "cloud scale". Aligned with the release of SharePoint 2013, Microsoft brought Service Bus "OnPremise" and developed a new Workflow Engine that will drive many, if not most future iterations of Microsoft products requiring any type of workflow or messaging. Now everybody has access to those. Both technologies are available now free to use in your own applications or solutions. This talk will introduce those to .NET Developers and demo how to use them.

    Code Portability in .NET

    by Barry Stahl

    Using .NET Portable Libraries and the Dependency Injection pattern we will build an application with versions that run on 3 distinct platforms (Win8, WP8 and the Web), with the goal of achieving the greatest possible reuse across those platforms. The techniques we use will minimize the code we have to create without having to resort to the source-control trickery of the past. This session will be extremely code focused as most of it will be spent in Visual Studio, creating code.

    Powershell for .Net Developers

    by Brad Candell

    Powershell is a robust scripting and automation tool created to perform administrative tasks within Windows. While it initially focused heavily on system administration, Powershell has become more integrated within our development world (Nuget, Azure, etc). What is better? The fact that it is built entirely on the .Net Framework and all its glory!

    This session will provide a brief introduction to Powershell and its concepts and explore the following:

    • Ways that a .Net developer can utilize Powershell
    • Syntax differences between Powershell and .Net
    • Developing custom Powershell Commands (Cmdlets) in C#
    • Integrating Powershell into your C# applications

    From Ruby to Haskell: how they are more alike than you might think!

    by Chris Wilson

    This is a talk about the similarities between Ruby and Haskell. It is also an introduction to either; though you'd have to be familiar with the other! I'll show how you can develop code in a cycle between testing, type checking, and refactoring that's reminiscent of the "red, green, refactor" cycle. I will give some short code examples and then develop a more interesting small/medium example. This is a focused version of a series of blog articles that I've written: http://bendyworks.com/geekville/articles/2012/12/from-ruby-to-haskell-part-1-testing (only one is currently published).

    Documentation Driven Development

    by Corey Oordt

    Developers usually leave documentation as a final step; one that they will get to as soon as they are forced with threats of bodily harm. Writing the documentation before writing the code, can lead to better code, better implementation and, of course, actual documentation. This talk isn't just about philosophy. It covers actual experiences and contains practical tips and solutions to get started. Discover how easy it is to write down your ideas and iteratively develop the documentation. Learn some of the tools to use to make your documentation look great. Find out that writing things down doesn't have to be a chore, but can be liberating, and helpful when working with non-technical people.

    Using Lean for Product Development

    by Doug Rhoten

    Build it and they will come, right? Right?! As developers, it’s very easy for us to fall into the trap of building products by adding feature after feature of what we think users or customers may want in an application. Before you know it, you’ve amassed a large amount of technical debt in an application where very few folks use all the features or worse, no one buys. What if there was a tool you could use to help keep you focused, validate your idea before writing a line of code and help save you time and money? In this session, we’ll cover the basics of the Lean Startup process and learning how to apply it to product development through using the Validation Board.

    Building a Single Page App the Easy Way With Durandal, Knockout and FluentKnockoutHelpers

    by John Culviner

    So you want to write a single page app eh? I’m not going to pretend that there aren’t lots of frameworks out there to get the job done but something about Durandal.js feels different – it’s simple, it runs on Knockout.js for MVVM goodness and importantly you don’t have to write much code! FluentKnockoutHelpers builds on the power of Knockout by using .NET and the Razor view engine to create ‘ASP.NET MVC like’ statically typed helpers for use with Knockout. Utilize static typing, intellisense and the compiler you already have in .NET to make Knockout development easier! In this presentation expect to learn some pros and cons of SPAs including reasons to create a SPA in the first place. After that we’ll dive right into the code of a non-trivial SPA utilizing Durandal.js, Knockout.js, Require.js, Razor and WebAPI.

    From the Front-line: Windows 8 Store Apps by the Numbers

    by Josh Pierce and Joe Luhman

    This talk, presented by See Sharp Guys, will provide real-world numbers from an independent development team focusing on building applications for the last frontier in app stores: the Windows 8 Store. The Google Play store has the largest install base, and iOS undoubtedly generates the most revenues. But for developers looking for a new opportunity, can the Windows 8 store offer opportunities the established players can't? During this talk, we will demonstrate how it's still early days in the Windows 8 store, and now is the time to get your app in the store and capitalize on this new and growing market. We will cover what we have seen by having a top 10 app, a top 100 app, and a low-tier app in the store at the same time. During the second portion of our talk, we will do a 'deep dive' and look at analytics of user behavior inside mobile applications, what metrics drive revenues, and how you can capture metrics in your app (whether on Windows, Android or iOS) to increase your revenues too.

    Real-Time Web Applications Using Windows Azure and SignalR

    by Justin Wendlandt

    Let’s face it, devices and apps are going to become a crucial part of our everyday life. Tickers, dashboards and real-time systems will become more ubiquitous and stuffed full of data than we see today. The philosophy of the world wide web being a medium for static data is almost non-existent, yet the infrastructure hasn’t changed in years. In this talk, we will explore how Microsoft proposes to solve this issue with SignalR, Azure Service Bus and ASP.NET MVC 3 to build a horizontally scalable solution to a real-time internet problem.

    Diving Into the Deep with Web API

    by Kamran Ayub

    You've watched introduction videos and presentations, you've played with Web API, and now you're considering it for a real-world project. In this session, we'll go over multiple issues with using Web API "in the real world" including debugging, IOC, custom routing, error handling, working with the client-side, versioning, anti-XSS protection, async actions, authorization/authentication, and working with multiple front-ends (Windows 8 and the web). This session is intended for those who are already familiar with Web API, but everyone is welcome. Kamran will be using his own project as an example, for better or worse, and would love for attendees to bring their own experiences to the discussion. Code will be slung, questions will be raised, and knowledge will be shared.

    C# From Abstract to Yield: How Well do You Really Know C#?

    by Keith Dahlby

    With each successive version, C# has added more and more keywords to do new and (mostly) exciting things. Before you can use them, you need to know they exist. From flagship language features like async and LINQ, to the subtleties of co- and contravariant generic type parameters, we'll discuss every language keyword/operator and provide some context for when you might see it in the wild or want to use it yourself.

    No-screen User Interfaces

    by Kevin Whinnery

    Does your application send users a text message when their order has been filled? Can they place an order by sending you a text? Can you interactively ask a user for pertinent information while they wait on hold for a support rep? Can you call them back when a rep becomes available? Can a user speak with a sales person in their browser if they have a question about a product on your web site? These are just a few opportunities, beyond the LCD or touch screen, that you might be missing to interface with your users. There are approximately 7 billion users on the global telecom network. That's over twice as many as computers and smart phones combined. Creating rich voice and SMS interfaces will allow you to reach more people and serve your existing customers better than ever before. Twilio makes creating these "no-screen" user interfaces incredibly easy. If you've created a web page before, you've already got what it takes to create a phone or SMS interface with Twilio. In this session, we will explore how and where to add telephony into an existing application using the Twilio platform. After a high-level overview of Twilio, we will live code new voice and SMS features into an existing web application. We'll demonstrate how developers can receive and respond to text messages and voice calls, and how developers can reach out to any of the ~7 billion users on the global telecom network at any time. Finally, we will demonstrate how developers can turn any web browser, iDevice, or Android device with a network connection into a VoIP telephone using Twilio Client. Code examples will be primarily JavaScript and Ruby, but the core concepts will be applicable to any server-side programming environment. No previous experience with telecom or a particular web development framework will be assumed. Voice and SMS are the next frontier of usability, and Twilio can help you blaze the trail.

    Dipping Your Toes Into Mobile: The Low-Hanging Fruit

    by Vince Bullinger

    Mobile development used to be a niche development platform. Many of us shied away from it due to unfamiliarity, lack of computing power, diversity of development environments for different devices or because we scoffed at its insignificance. Those of us who did are now behind the times. Mobile browsing will be the PRIMARY browsing environment in the next couple of years and just about everybody has a smart phone and/or tablet. The revolution is here and you must adapt. For the developer that's been reluctant to make the switch, we'll be going over the low-hanging fruit that's been developed in the last few years by people sharing your concerns that will help you ease into the mobile development world including PhoneGap, jQuery Mobile, mobile websites and responsive web design.

    How To Pitch a Groovy Tent in a Java Code Base

    by Wendy Istvanick

    Do you often find yourself writing yet another Java web app while secretly, or not so secretly, envying your co-workers who are playing with Ruby or Clojure with features like closures that make it so much easier to express yourself? If the answer is yes, perhaps you should be taking a look at Groovy. It sort of looks like Java, acts like Java, and under the covers really is Java (i.e. it compiles to byte code) so one could say it acts like a duck, talks like a duck, and therefore must be a duck. So, what exactly is that duck? It is a language that - supports closures for functional programming - can be either dynamically or statically typed (depending on the preferences of the programmer or the context of the code) - has built in mocking, which achieves great power through closures, while at the same time - looks like and plays well with Java - interoperates with Spring - is understood by IntelliJ Interested, come and chat about real life experiences of Groovy into Java code bases.
