More and more applications are being written in dynamically typed languages like JavaScript and Ruby. Theoretically, this is progress. But, what happens when they go bad? What are the recovery options. This talk explores methods for making sense of, and recovering large legacy code bases in dynamically type languages. It concentrates on the differences between them and their statically-typed counterparts.

There are several current trends that are forcing application architectures to evolve. Users expect a rich, interactive and dynamic user experience on a wide variety of clients including mobile devices. Applications must be highly scalable, highly available and run on cloud environments. Organizations often want to frequently roll out updates, even multiple times a day. Consequently, it’s no longer adequate to develop simple, monolithic web applications that serve up HTML to desktop browsers.

Facebook chat used to be notoriously unreliable. User complaints about disconnection, incorrect message counts, and missed messages dominated Facebook’s overall product feedback. New code frequently caused regressions because of untracked dependencies in our ginormous, monolithic Javascript codebase.

Learn how a team developed a lightweight JavaScript real-time event-driven platform utilizing WebSockets and proven open source technology such as jQuery to enable a cross platform mission operations center.

Javascript is ubiquitous. Node.js tries to be the next PHP but it just can’t. This talk presents an experiment that freaked out many people: NodePHP. NodePHP is an inline PHP server running on Node.js During the talk, the speaker goes over what “node-php” is and more importantly how is that possible or why would anyone do this. Towards the end, he shows how the two technologies can be coopetitors rather than competitors.

Almost two decades after the birth of JavaScript, its creator gives a whirlwind history of the language with stories (and dirt!) dished out from each era. What worked well for JavaScript and what has continued to make developers groan? What’s coming in ES6 and where next for the JavaScript community? Brendan Eich, responsible for architecture and the technical direction of Mozilla, answers to these questions and more.

There are 1 thing(s) that you have probably noticed about l10n and I18n in your JavaScript App(s). The sentences, even in english, are as ridiculous as the first one in this paragraph. Sure, you may be used to it, but it’s a crappy user experience. There’s lots you can do to make your data driven sentences valid, even expressive, in your language, and then expand that to any language. This talk will round up a set of tools and techniques to help prepare you to write apps that don’t sound …

This talk will cover both pitfalls and opportunities of single-page applications, with a focus on native behavior that your application needs to provide in order to behave like an actual web site, while fixing a lot of the usability issues that web sites usually have.

Learn how to structure web applications by using the good old Model-View-Controller pattern in the browser rather than on the server. You’ll learn how to build models with key-value binding and custom events, collections with a rich APIs and views with declarative event handling. You’ll also learn how to connect it all to REST interfaces built with the Service Stack API. After attending this tutorial you’ll be able to build modern web applications with super snappy user interfaces using technologies you’re already familiar with.

Do you write a lot of HTML and JavaScript code to push and pull data? In this session, learn popular techniques to use data binding to bind your data to your target controls in HTML writing less code, but gaining more power. See how to consume json data, use json objects in JavaScript, use declarative binding, using KnockoutJS. Also, see how to use the MVVM pattern to write data centric JavaScript code that follows good separation patterns and creates highly maintainable code.
