Boomerang — measure your site's performance from your end user's point of view, Philip Tellis (video | slides)
Monday, November 8, 9am

As a web developer, you probably care deeply about the performance, security, accessibility and internationalisation aspects of your site. You do a lot of testing during development to make sure your web site follows best practices. Tools like YSlow and PageSpeed help you identify and fix performance problems during development, but it's still very hard to tell how your site performs from your end user's point of view.

Are your users on dial-up, wireless or broadband? Do they have fast computers, are they on a shared network? What else do they have installed that can slow down their browsing experience? It's almost impossible to simulate all conditions that a user will browse your site with, but it is possible to measure what they experience.

This talk will show you how to use the Boomerang library to test your site's performance from your user's point of view.

Building YQL Open Data Tables with YQL Execute, Nagesh Susarla (slides)
Tuesday, November 9, 1:45pm
Yahoo Query Language was built with a goal of making webservice access simpler. In our endeavor, we realized that it was essential to expose a familiar language to augment, enhance and manipulate data from the plethora of web services and provide a consistent API. This led us to choosing server side JavaScript as the language. In this talk, we'll cover the various features and APIs at the Table author's disposal which make mixing and matching web services easy. All this with the power of simple and pure server side JS.
Creating Wow! web graphics with YUI extensions for SVG, Vincent Hardy
Tuesday, November 9, 11:45am
This session demonstrates how YUI can be used with SVG (Scalable Vector Graphics) to create rich, animated and interactive graphical effects. After showing examples from the svg-wow.org web site, the session will show in detail how the gallery-svg module for the YUI gallery can be used for simple examples (such as animating shape properties) to or more complex ones (such as morphing shapes or animating filter effects).
CSS 3 Beyond The Hype, Nicole Sullivan
Wednesday, November 10, 11:45am
This session will cover practical techniques for using CSS 3 to eliminate unnecessary images and make your site super fast. It will also cover places where the new technologies break down and discuss ways of giving IE users the best possible experience.
Finger Tips: Lessons Learned From Building a Touch-Based Experience, Mark Kawakami (video | slides)
Tuesday, November 9, 3pm
Creating a touch-based interface for devices like the iPad and iPhone is easy with YUI 3. But giving your users a truly great experience means paying attention to details such as finger size (they're big) or the speed of the devices (they're slow). Mark will share some of the lessons his team learned while adding touch support to Yahoo! Fantasy Sports, including tips like replacing "fancy" with "fancier" and the value of procrastination.
Handling Data in YUI3, Tilo Mitra (video | slides)
Tuesday, November 9, 9am
An overview of how to work with data across its entire lifecycle: Retrieval, Parsing, Normalization and Display. Along the way, we'll cover various YUI 3 utilities and widgets which make working with data super-easy, such as Datasource, Dataschema, Datatype, Recordset, Datatable, Autocomplete & Charts. Working code will be provided.
High Performance JavaScript, Nicholas Zakas (slides)
Tuesday, November 9, 3pm
Ever wonder why the page appears frozen or why you get a dialog saying, "this script is taking too long"? Inside of the browser, JavaScript and the page's UI are very intertwined, which means they can affect each other and, in turn, affect overall page performance. Ensuring the fastest execution time of JavaScript code isn't about geek cred, it's about ensuring that the user experience is as fast and responsive as possible. In a world where an extra second can cost you a visitor, sluggishness due to poor JavaScript code is a big problem. In this talk, you'll learn what's going on inside the browser that can slow JavaScript down and how that can end up creating a "slow page". You'll also learn how to overcome the conspiracy against your code by eliminating performance bottlenecks.
How to stop writing spaghetti code, Tom Hughes-Croucher (video | slides)
Tuesday, November 10, 9am
This talk will examine different coding styles for event driven, non-blocking SSJS and which styles are most successful.
HTML5: Right Here, Right Now, Tantek Çelik (video | slides)
Monday, November 8, 4:30pm

HTML5 is the first major revision to the web's lingua franca in over 10 years and disrupting web development as we know it.

In this presentation Tantek illuminates what makes HTML5 both easier and more powerful, which HTML5 features are ready now, roughly usable, unfortunately ugly, or worthy of web application experiments. HTML5 is also a work in progress - learn how by using it and providing feedback, anyone can help shape this important update to the foundation of the web.

Finally, Tantek will touch on a little bit of CSS3, microformats, and Javascript that every professional web design or developer speaker should be using.

Internationalizing Applications Using YUI 3, Norbert Lindenberg (video | slides)
Wednesday, November 10, 9am
On the web as in the real world, every language is a minority language. To reach a majority of users, your software will need to support multiple languages and be adapted to the needs and expectations of different cultures. This talk discusses how to do this building on YUI 3.
Introduction to YQL, Mirek Grymuza & Josh Gordineer (video)
Monday, November 8, 11:45am

Node.js Roadmap, Ryan Dahl (video)
Monday, November 8, 3pm
Node is meant to be a minimalistic system for doing non-blocking I/O with javascript. The initial implementation is usable and generally fast, but there are many cases where needed features are missing and performance is not good. In this talk I will explain what I see was Node's deficiencies and how they are being addressed.

Taxonomy of Touch, Nate Koechley (video | slides)
Tuesday, November 9, 1:45pm

You may now use direct manipulation for fun and profit. Finger replaces mouse. Direct replaces indirect. Users swipe, flick, pinch and tap where recently they clicked and clicked and clicked. And it's not just for phones anymore.

But some things don't change: Complexity accumulates and must be engineered down. Idioms emerge and diverge, and standards must arise. Normalization is necessary and tooling is needed. As the new outcroppings of touch appear on the landscape, YUI will once again lend a hand, joining forces with us all to tackle these challenges in the service of our users. In this session we'll survey the current landscape of touch across multiple devices and use cases. We'll identify where patterns are emerging, where YUI is engaging, and where we can all get involved.

Followed up with a dive into TipTheWeb's advanced usage of YQL to process our most important data, URLs; making YQL the place where web service requests are made and data is gathered.
Understanding Progressive Enhancement with YUI: Write Less, Achieve More, Christian Heilmann (slides)
Tuesday, November 9, 4:30pm
There are a lot of myths about progressive enhancement and it gets a bit of a bad rap from people "on the bleeding edge". In this talk Chris Heilmann will show you how embracing the idea of progressively making a system more complex after testing for support will make you build great solutions faster and in a more maintainable fashion.
Using (Not Abusing) YQL for Caching, Filtering and Collating Data, Christian Heilmann (video | slides)
Monday, November 8, 1:45pm
YQL and webservices go very well together. Using the query language to get all kinds of information of the web to remix is amazingly easy, and powering your web sites with YUI and YQL will make you create compelling demos and systems in a matter of minutes. There are however some dangers in the use of YQL with JavaScript and in this talk Chris will show how to avoid them and use HTML5 solutions for niggling problems of the past.
A Whirlwind Tour of AlloyUI Components in the YUI 3 Gallery, Nate Cavanaugh & Eduardo Lundgren (video)

Yeti: YUI's Easy Testing Interface, Reid Burke (video | slides)
Wednesday, November 10, 3pm
Testing cross-browser web applications has been too difficult for too long: You're either manually reloading browsers or struggling with complicated automation software. YUI changed all of that with Yeti.

Yeti delivers your test results from any number of browsers with one command. Yeti requires no "driver" software—if you can navigate a browser to a web page, you're set—so it's ideal for mobile device testing.

In this session, you'll learn when you should use automated testing, how Yeti works with YUI Test, how to setup cross-browser testing in minutes and how the YUI team uses Yeti to ship a better product.

You'll also learn how Yeti itself, written in JavaScript, leverages Node.js to make it all possible.

YUI 3 & NodeJS for JavaScript View Rendering on Client or Server, Matt Taylor (video | slides)
Monday, November 8, 4:30pm
The premise of this idea is to enable data to be translated into HTML either on the browser or the server. The only way to do this on the browser is with JavaScript, so we must have JavaScript on the server as well. Good thing we have NodeJS. Most web application frameworks have some type of templating engine that accepts two things: (1) data, (2) template, and returns HTML to be assembled into an HTTPResponse. But what if we could take the browser-side JavaScript function that handles the XHR response data and run it on the server? With the nodejs-yui3 module, we can! Recommended prerequisite: Node.js + YUI 3 / Dav Glass.
YQL + YUI: Building End-to-End Applications , Nagesh Susarla & Paul Donnelly (video | slides)
Wednesday, November 10, 10:15am
When developing widgets it's not how to use YQL data that comes up in question, but how to access it. We'll go over starting your query out in the YQL console, how to access YQL data via the various endpoints and going through YQL's various authentication layers.
YUI 3: Below the Surface, Luke Smith
Wednesday, November 10, 9am
A look inside some of the core patterns and infrastructure pieces that lie at the heart of YUI 3. This talk is not about sugar; there will be JavaScript. You've been warned.
YUI 3 Loading Strategies: A Yahoo! Search Case Study, Caridy Patino (video | slides)
Wednesday, November 10, 4:30pm
A robust loading strategy is one of the most important pieces when you think about optimization for high traffic websites. YUI Loader is a wonderful piece of software, and learning how to leverage it is a MUST-HAVE for YUI developers. Dynamic injections, controlling early user interactions, parallel downloads, preloading asssets, and window-iframe loading strategies are some of the topics that Caridy will cover in this presentation that examines Yahoo! Search as a case study.
YUI Test, Nicholas Zakas (video)
Tuesday, November 9, 3pm
JavaScript testing has grown by leaps and bounds over the past few years. When YUI Test was first introduced in 2007, it was just the first step in a long process of bringing test-driven development to the front end. YUI Test evolved with the release of YUI 3 to introduce mock objects as feedback indicated a need. As feedback continued to come in, YUI Test continued to evolve. Learn about the next version of YUI Test, how it makes testing any JavaScript code easier, and the brand new tools that allow you to integrate your testing into a continuous integration environment.
