Session description

The Canvas tag has been around for a while, and HTML5 has given it more visibility. It’s now finding its way into most mobile browsers, and even a majority of desktop browsers. This talk will give a solid overview of what the canvas tag is, what it can do, and how it compares with other technologies like SVG and Flash. Several practical code examples will show how you can use it along with CSS3 and other HTML5 goodies to make your web apps more featured, efficient and downright cool.

Session description

While location-based mobile apps are becoming increasingly popular, they are still relatively new. Special considerations need to be made for battery life and handling large data sets of geolocated data. The good news is there are many services and technologies you can use to assist you in building mobile location-based apps.In this session, Aaron Parecki, co-founder of Geoloqi.com, shows you services you can leverage to do things like nearby business lookups, location-based triggers, nearest intersection queries, and more. Aaron also covers the location services available on the various mobile platforms as well as in HTML 5, and shares some insights on how to deal with battery life. The session concludes with some real-world use cases for real-time location such as turning on and off your lights in your house or notifying your boss if you’ll be late to work.

Session description

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.

Session description

The USA and UK governments have made significant progress with linked, open data in recent months. Several fundamental datasets from the Australian Government are on the cusp of being exposed as meaningful, reusable, machine-​​readable assets, further driving the adoption of linked data within and around government.Making better use of online data offerings using a combination of top-​​down policy and guidance, together with bottom-​​up development efforts from agency web teams, would seem to describe a sustainable, organic growth in linked government data.Learn about the path to the first release of data​.gov​.au; a draft roadmap to future releases; the barriers to linked data and open public sector information (PSI); and the real-​​world questions this technology aims to solve.

Session description

Remember how fun it was to do hands-on classroom projects together in kindergarten? Well, this interactive session is going to be like that, but just with bigger people.In the first part of the session, I'll hand out blank report cards, and each of us will -- individually and based on whatever criteria we personally want to use -- use those report cards to assign A, B, C, D, and E letter grades to particular new features that are part of HTML5 and related specifications that are supported to some degree in browsers.Then I'll collect those, and use the info to judge which HTML5 features to focus the discussion on during the second part of the session. During the second part of the session, we'll make a handful of poster-side HTML5 Report Cards together, by taking a look at the HTML5 features we identified during the first part of the session, and then assigning A, B, C, D, and E letter grades to those together -- based on the current quality of the features/implementations, and on criteria such as if/how well the features actually work as expected, as well as on some criteria such as "plays well with others", "areas where improvement is needed", etc.

Session description

RDFa is a W3C standard for embedding semantic metadata directly into HTML web pages. While early work on RDFa dates back to 2004, it recently gathered a lot of uptake and traction through the adoption by big players such as Google, Yahoo! and Facebook. This has put the Semantic Web into the attention of a much wider public, setting RDFa out the be the technology to finally bring the Semantic Web into the mainstream. The language gained the status of a W3C recommendation in late 2009 as RDFa 1.0. Since then, the RDFa working group has been established to improve and extend the standard. Eventually, this work will result in a new version of the language, which is set to be released as RDFa 1.1 in 2011. In this talk, an overview will be given of the RDFa technology in general, followed by an outline of its latest developments, such as the RDFa API, or the definition of RDFa Core, which prepares the standard to extend its scope beyond the context of web pages, by allowing it to be included into any other markup language than just HTML.

Web technologies are evolving at such a frenetic pace that it becomes almost mandatory to learn on your own. A lot of us still depend on other people to do this learning for us, and we tend to use their answers to solve our everyday problems. Inconsistent implementations, rapidly evolving specs, questionable performance impacts and maintenance implications mean we cannot always depend on others for answers but must involve ourselves actively in the process of developing specifications for new Web technologies. But how do we go about it? There are some simple rituals we can all do, which can have us be better-informed and also better inform the people and groups who are most directly involved in the development of new Web technologies.

Despite being an option on web servers as early as 1995 with Netscape's LiveWire, JavaScript has long been regarded as a language only of the browser.Approaching sweet sixteen JavaScript has evolved in the community and gained acceptance as a general purpose programming language.In this session Patrick will be looking at JavaScript outside of the browser, focusing on how to use it for web server applications. Starting with the old in Helma and progressing through various usages to the most new and exciting with node.js, Patrick will talk about why JavaScript on the server matters right now and show you how to get started using it.

Session description

There is no denying that the Apple App Store is huge, but who wants to have to deal with Objective-C? Thankfully, technologies like PhoneGap and Sencha allow web developers to work in languages they know (HTML/CSS/JavaScript) while still making them look native. PhoneGap also allows us to port our apps to other platforms, like Android. This session will look at the mobile web development lifecycle from building a prototype in the browser, integration with the phone, app submission and some basic marketing tricks.

HTML5 introduces several so-called “offline” technologies: application caching, local storage, and file access, to name a few. But these technologies are not just for purely offline apps; they boost startup performance, overcome network outages, and partition content away from the server. This talk will explain how you can incorporate these technologies into your work today and identify the features browsers will be supporting in the near future.

Web 2.0 is adding more and more content to our pages, especially features that are implemented in Ajax. But our web applications are evolving faster than the browsers that they run in. We don't have to rely on or wait for the release of new browsers to make our web applications faster. In this session, Steve Souders discusses web performance best practices from his second book, Even Faster Web Sites. These time-saving techniques are used by the world's most popular web sites to create a faster user experience, increase revenue, and reduce operating costs. Steve provides technical details about reducing the pain of JavaScript, as well as secrets for making your page load faster in emerging markets where network connectivity is a challenge.

Presentation slides

These slides are available on the W3C website. In a masterstroke of self-referential genius, Doug's slides are in fact all created in SVG itself, so it may in fact be a little difficult to piece them together with the podcast. This was an amazing presentation though - you'll have to be there next time :).

Session description

This session will be a solid introduction to CSS3 by way of practical examples that can get you started using CSS3 on your projects today.Rachel Andrew will take you through some of the core features of CSS3 including advanced selectors, media queries and other features that are being developed and starting to be implemented in browsers.In addition to discovering how CSS3 will change the way that we develop in the future we will explore current and upcoming browser support. We will also see how it is possible to start using some of CSS3 in your projects now, with the help of a little JavaScript to plug the holes in current browsers.

Session description

Server-side JavaScript has really started to take off, with a number of great projects providing different pieces of the puzzle. This talk will introduce server-side JavaScript and provide an overview of the existing projects as well as some ideas about where it’s all going in the future.Tom will look at how the various JavaScript runtimes, such as V8 and Rhino, affect development and provide their own unique features. You’ll also see the standardisation effort of Common.js and why it’s shaping how people write server-side JavaScript.All the leading SSJS frameworks – Node.js, Narwhal, Jaxer – will be discussed as well as some more quirky uses of JavaScript on the server such as CouchDB and YQL.

The Canvas tag has been around for a while, and HTML5 has given it more visibility. It’s now finding its way into most mobile browsers, and even a majority of desktop browsers. This talk will give a solid overview of what the canvas tag is, what it can do, and how it compares with other technologies like SVG and Flash. Several practical code examples will show how you can use it along with CSS3 and other HTML5 goodies to make your web apps more featured, efficient and downright cool.
