Asynchronous User Interfaces - the future of Web UIs

Asynchronous UIs are a complete revolution in the way programmers are creating interfaces for the web, with an emphasis on speed and client-side state.

This talk will take you through all the steps needed to implement an asynchronous UI, from serving up JSON to rendering everything client side with frameworks like Backbone and Spine.

Pure, Functional Javascript

Are you comfortable passing functions around, returning them from other functions, and generally enjoy the pleasures of higher-order functions? Join in on a brief hour implementing ideas from functional programming in JavaScript. I will show you how you can significantly up your game by leaving loops behind and embracing functions as your primary unit of abstraction.

Pure, Functional JavascriptChristian Johansen

Christian is a passionate programmer currently working at where he does everything from JavaScript to Ruby to Unix systems tuning. He is the author of "Test-Driven JavaScript Development", and he maintains several open source projects, including the recently released test-framework Buster.JS and the popular mocking framework Sinon.JS. After dark you may find him tinkering with his Emacs setup, coding Lisp and slowly being devoured by the world of functional programming.


Unlock your Inner Node.js in the Cloud with Windows Azure

If I told you that you can build node.js applications in Windows Azure would you believe me? Come to this session and I’ll show you how. You’ll see how take those existing node apps and easily deploy them to Windows Azure from any platform, how you can make yours node apps more robust by leveraging Azure services like storage and service bus and how to take advantage of cool tools like for WebSockets, node-inspector for debugging and Cloud9 for an awesome online development experience.

Building Real-Time Web Applications with ASP.NET SignalR

WebSockets is introducing web developers to a whole new world of real-time programming but that isn't the end of the story. SignalR gives ASP.NET developers the ability to build real-time web apps that work both with and without websockets and with an API so easy to use it almost seems like magic (really). You want scale too? No problem; SignalR scales out with your application. Come and see why web programming will never be the same again.

Web Performance

Speed is an essential for a great web experience but it often gets overlooked.

We'll examine how speed affects the users' experience and cover some ways we can measure and analyse it.

Then we'll run though optimisation best practices, take a look at how browsers and networks affect load times, before diving into some of the challenges the mobile web and the dangers third-party javascript bring.

Web PerformanceAndy Davies

Andy is a freelance consultant who first stumbled into web performance in late '90s when he was trying to deliver e-learning over dial-up connection speeds and has been hooked ever since. Based in the UK, Andy helps companies measure, analyse and improve the performance, and reliability of their web sites and applications. Before going freelance, Andy led the development and delivery of web-based products across a variety of sectors including education, ecommerce and logistics.


TypeScript: JavaScript development at Scale

TypeScript is a new programming language aiming to improve the development experience of writing and maintaining application-scale JavaScript programs. TypeScript is a superset of JavaScript, adding optional static typing to improve the tooling experience, as well as EcmaScript 6 style classes and modules to help organize large programs. The TypeScript compiler is open source and translates to plain JavaScript that runs in any browser on any platform.

The power of node

Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

This talk introduces node.js by exploring practical examples of suitable use cases.

Expect lots of code, demos, and a clear analysis on the strengths and weaknesses of node.js as a plattform.

Nashorn: Optimizing JavaScript and dynamic language execution on the JVM

There are many implementations of JavaScript, meant to run either on the JVM or standalone as native code. Both approaches have their respective pros and cons. The soon-to-be open sourced Oracle Nashorn JavaScript project is based on the former approach. This presentation goes through the performance work that has gone on in Oracle’s Nashorn JavaScript project to date in order to make JavaScript-to-bytecode generation for execution on the JVM feasible.
