Mobile Web Workshop (Web Bowling)

Build a Web Bowling game using HTML5, CSS, accelerometer and gyroscope, web sockets, and Box2D physics.

Hey wii bowling fans, in this workshop you will learn how to build a mobile web client that utilizes the accelerometer and gyroscope data of your smartphone to build a control for throwing objects at a remote display. We will create a node websocket server for handling the communication between the controller and the display. On the display we dig into the fantastic JavaScript Box2d physics engine to create obstacles for our remote objects to crash into. Come see just how easy this is to do and build a souvenir to take home to your kids that they really will enjoy a lot more than that starfish you were thinking of buying.

Browser Dev Tools Showdown

Every developer has their favorite tools and today when it comes to which browsers to develop in we have a few choices.

In this session we will be looking at the different dev tools that can be used in each of the popular browsers and discover their strengths and weaknesses. We will be looking at how to inspect elements in the DOM, use the JavaScript console, analyze network requests, spot problematic performance issues, tweak css and much more. Knowing how to use these tools and what they each offer can greatly increase your productivity as a developer and help you quickly troubleshoot browser issues. We will be focusing on Chrome's developer tools, Safari, Firebug and IE.

Native Mobile vs. The Open Web

We will be exploring the features and capabilities of native platforms and comparing them to what is available via the mobile browsers. The strengths and weaknesses of both native and web approaches will be demonstrated through example applications and code.

Comparisons and debate will include graphic acceleration, persistence, geolocation, orientation changes, offline support, camera, file system access, overall experience, etc. We will touch on industry trends, what development organizations are doing, and what technical research firms are predicting.

netty vs. node.js

Node.js and Netty are both frameworks for building scalable network applications. While Node.js runs on Chrome's V8 JavaScript engine and Netty runs on the JVM, they both have a similar architecture for building event-driven network applications.

This presentation will compare each framework’s pros and cons and discuss their weaknesses and strengths.

JavaScript Puzzlers

We will be going through a handful of strange and seemingly anomalous JavaScript programming puzzles in the style of Joshua Bloch's entertaining and enlightening game show.

The goal of the presentation is to highlight some of the less understood pieces of JavaScript in an engaging format. Understanding some of the subtle nuances of the language will allow developers to deliver cleaner, more bug-free code. Come to see how well you do at answering these puzzles.

Web Gaming APIs and their applications in business

In the last couple months many new gaming APIs have landed in the latest browsers. These APIs give game developers better access to hardware and device resources. They also provide significant performance improvements to existing code.

In this presentation I will demonstrate how these gaming improvements can be used to improve enterprise application experience and make business logic more efficient.

The Web API

The WebAPI is providing developers with the ability to interact with device hardware and resources that have only been available to native platform stacks. Through the WebAPI web developers now have access to battery levels, screen orientation, cameras, background services, the file system, network status, radios, and much more. We will step through each of the APIs within the WebAPI showing code, demos, and browser support.

The objective of this presentation is to give participants an idea of the many new things that can be accomplished via the web.

Vert.x vs. Node.js

Node is fast, dynamic, and trendy. Vert.x is practically unheard of. But some people claim that Vert.x could be the Node killer.

We will compare the two and outline their similarities and differences.

Simpler Social Integration using API Mashups

Each day our mobile gaming platform is becoming more and more capable. Each day the need to send games to the mobile browser increases. Many game designers are forcing developers into the same social integration UI flows that Desktop browsers have.

This class will show many different ways to connect your users with their friends, by using combinations of the new APIs available in our gaming device browsers. We will cover bump and simple gaming auto. Additionally we will unveil a new concept audio-signal auth to allow for seamless broadcast authorization.
