With the mobile world becoming more complex with platforms like Palm webOS, iOS, Android, Blackberry, and Symbian all with growing user bases, how can you build applications that target a wide variety of devices? In the past, the solution was J2ME (boo! ;), but now the common denominator for the smartphones of the world is WebKit, the HTML5-based engine that's powering today's smartphones.
The Web has the opportunity to be the unifying platform, but really? How can you actually create a Web application that spans all of the platforms? There is an exciting new world brewing. A world that isn't about a "browser" but is about a global runtime. Learn how the computing game has changed, and how you can disrupt the industry using productive and fun technology.

Straight from the JSConf.us talent pool comes the wonderful Jenn Lukas. If you missed her talk in the US, go watch it on blip.tv (when it is released :) because here comes part 2:
Doing animations in the dark ages of the internet led you to technologies like Flash, or even Java Applets. Early arcane magicians tried bending the will of the DOM to create shiny stuff. It felt wrong.
With HTML5 two technologies arrived to fix that: Say hi to Canvas and SVG!
Our talk will cover basic usage and use cases of both technologies. By showing demos and real world examples we'll try to give you an understanding of when to choose what. Eventually we will show you libraries based on Canvas or SVG which should save you some time.

Be prepared to have your mind warped and molded as you are trained to not only accept this fact of life, but embrace it. You'll even be thinking in callbacks by the time this talk is over.

You like the idea of Object Oriented CSS, but your website has out-of-control CSS bloat. You know your performance is being impacted, but how do you move from organic CSS with no particular architecture to something lighter, more logical, and easier to maintain? How do we automate some of the heavy-lifting and stop wasting our own time?
CSS is typically the most difficult layer to automate, but a more clearly defined CSS architecture makes lint much more powerful. In this session, Nicole will show you how she improved the CSS at Facebook and demo tools that you can use to test your own CSS.
For a variety of reasons CouchDB and node.js are a perfect fit. This talk will focus on node.js tools and utilities for accessing CouchDB, writing Couchapps and responding to _changes events.
Felix was supposed to speak at JSConf 2010 in Washington, DC, but then there was a volcano!
What would happen if your database would have no network interface, no query abstractions and less than 250 lines of node.js code? You would end up with a very flexible in-memory database that is wonderfully suitable for dirty tasks such as rapid prototyping or performing millions of GET/SET operations per second.
This talk is about rethinking current database technology and exploring situation-based CAP tradeoffs.

Building native mobile applications across platforms with PhoneGap is super easy but developers are still required to install a dizzying array of SDKs for: iOS, Android, Blackberry, webOS, Symbian, MeeGo and Windows Phone. At JSConf.eu the PhoneGap team is releasing a special sneak peak at two new projects which aim to solve this problem. Unlike our previous sessions which have been information dense lightened up with pixel art and 4chan pictures this session will be more code intense: with pixel art and 4chan pictures!
In order to find out whether node.js is ready for production use and to scratch an itch, tempalias.com was started as a fun project.
The service allows anybody to create a temporary email alias with a limited validity (either time- oder usage based). Mail sent to that alias within the validity constraints is then forwarded to any address of your choice.
The talk gives a behind-the-scenes look on how the (free software) project was built and how its architecture works. On the process, we'll learn how to build a web application without dynamically generating a single byte of HTML on the server side, how SMTP works, and how to implement a bookmarklet without destroying arbitrary target pages. And we'll learn how to design a daemon in a way sure to bring your server down under load :-)
Aside of the technical issues, we'll also have a look at how to be a good citizen in the open source community by providing upstream with usable and easily applied patches. And as it's the case with all cool free services, we'll learn how to deal with Spammers.

The area of Research and Development (R&D) in software, web and user interface engineering is making quite a statement in many large and small scale organizations lately. With such a vast amount of data and web service APIs available to developers, coupled with a huge demand for multiple systems integrating seamlessly across several platforms and devices, it should come as no surprise that companies are creating "Labs" departments left and right to create the "next big thing."
In order to cultivate innovative products and services, designers and developers need to research, ideate, and collaborate to develop creative approaches to current products or services, or even fill voids for users for products or services that have not been created. Developers need to quickly build out prototypes of these ideas in order to not only implement the ideas and prove the value of the concept, but to also provide new products and/or services for the business itself (and keep the R&D department alive!).
From My Presentation, You Will Learn...
What rapid prototyping is and why it is important.
Tips on baking in ideas like performance, scalability, and maintenance into the prototypes and why you should avoid them.
How to utilize a single codebase for usage across various devices and platforms including the desktop browser, the mobile browser and mobility products (e.g. Ipad).

Plugin-independent client side data storage, like HTML5 powered localStorage or IndexedDB, is becoming more relevant every day, though it had been there for ages. In fact, IE 5.5 was the first browser to offer data persistence in other forms than cookies. However, today, as we are online most of our time, handling offline situations has become important for many web apps. And for mobile dev, storage is crucial: You wouldn't want to pull some hundred k of data via a slow connection again and again.
"This talk will take a tour around existing client side storage mechanisms. We'll start with cookies and see why it's a bad place to stay. Then we'll quickly move on to the good neighbours, visiting ancient places as well as futuristic ones and investigating their ins and outs. And we'll also stop by the frameworks/wrappers that give easy access to them. To make things more interesting, we'll then board a submarine and dive into the crazy world of mobile devices, it's special demands and see what options exist over there. Finally, we'll have a look at performance and security concerns. Don't forget your towel!"

HTML5 and friends have been getting implemented in browsers at an impressively quick pace. But that leaves us as web developers wondering, "Great, but how am I supposed to build cross-browser applications with these features when I still have to support IE".
We'll take a look at what the landscape of implementable features are, detailing best practices of implementation and fallback solutions where appropriate. For example, how do you pair WebSockets with a standard comet stack and what do you have to watch out for.
We'll also review your available feature set if you're only targeting webkit mobile, or if you've already given IE6 the boot.
The data will be up-to-the-day accurate, covering all major browsers and filled with best practices from topic experts.
After last year's standing ovations performance, he is back. His last talk's video was viewed 12 thousand times. We're excited what will happen this year.

Mobile applications are a huge trend at the moment. But there is one major drawback: You need to develop them from scratch for every-single-platform. That hurts. Web technology seems like a natural choice to develop cross platform and fundamentally increases efficiency during development. This talk is about the richness of Unify applications, the focus of the project and our future plans.
Socket.IO provides an API that enables WebSocket for every browser (IE5.5, IE6, IE7, IE8, Safari, Chrome, Firefox 3-4, Opera 10) and multiple mobile devices (including the iPhone and the iPad).
I'll talk about how you can get started using Socket.IO today, how people are using it in production environments, and how to create realtime web applications with just a few lines of code.
We're really proud to have a large number of Bespin devs at JSConf.eu. Three of them will give us a heads up on their work:
In this talk, the Mozilla developer tools team will run through what Bespin can do for you, how you can customize it and where the project is headed.
Meet the person that made deep linking into things that used have no URIs possible:
"Do you want to take your AJAX powered website to the next level by making it easily accessible through deep links? And how about making all the dynamic data available to the major search engines? Come and learn more about all the existing and evolving techniques, the best practices and details that you should have in mind."
