6:00 - 7:00: HTML5 Geolocation, by Scott Ryan

 HTML5 introduces a standardized access to geolocation data.  We will look at the interface and how to use the data.  We will explore the privacy settings and how they are handled as well as how to determine accuracy of the locations. We will look at how to utilize the data and how to implement a fallback if your browser does not yet support the HTML5 geolocation features.  We will explore this interface on Firefox, Opera and Android.

  • Laying the Foundation
  • Privacy and what it means
  • The Geolocation interface
  • How accurate are my results (speed versus accuracy)
  • How to use the location data for something useful
  • Fallback alternatives


7:30 - 9:00: Mobile HTML5: Optimize your website a little or a lot, by Scott Davis


Apple sold 4.1 million Macs in Q4 of 2010 -- an impressive number until you consider that they sold 7.3 million iPads, 9.1 million iPods, and 16.3 millions iPhones in the same timeframe. IDC reports that smartphones outsold desktop PCs across the board for the first time in history, and the trend is expected to continue in 2011.

The mobile web is here, and this talk aims to help you get your website up to speed. You can make some subtle tweaks to your existing website to make it more mobile friendly -- accounting for the smaller viewport screen size, providing layouts for both portrait and landscape mode, and making your hyperlinks mobile-friendly. Or you can optimize it a lot by providing a dedicated website that leverages HTML5 local storage, application cache, and more. 

As the mobile ecosystem continues to grow and fragment with devices from smartphones to tablets -- running iOS, Android, WebOS, and everything else -- having a coherent mobile web strategy can help smooth out the bumps and move you from a "one size fits all" mentality to a more adaptive, right-sized approach to web development.
