Creating Offline Web Applications With Dojo Offline
by Brad Neuberg (SitePen), September 23rd, 2007
This tutorial steps you through creating offline web applications using Dojo Offline.
What is Dojo Offline?
Dojo Offline is an open-source toolkit that makes it easy to create sophisticated, offline web applications. It sits on top of Google Gears, a plugin from Google that helps extend web browsers with new functionality. Dojo Offline makes working with Google Gears easier; extends it with important functionality; creates a higher-level API than Google Gears provides; and exposes developer productivity features. In particular, Dojo Offline provides the following functionality:
An offline widget that you can easily embed in your web page with just a few lines of code, automatically providing the user with network feedback, sync messages, offline instructions, and more
A sync framework to help you store actions done while offline and sync them with a server once back on the network
Automatic network and application-availability detection to determine when your application is on- or off-line so that you can take appropriate action
A slurp() method that automatically scans the page and figures out all the resources that you need offline, including images, stylesheets, scripts, etc.; this is much easier than having to manually maintain which resources should be available offline, especially during development.
Dojo Storage, an easy to use hashtable abstraction for storing offline data for when you don't need the heaviness of Google Gear's SQL abstraction; under the covers Dojo Storage saves its data into Google Gears
Dojo SQL, an easy to use SQL layer that executes SQL statements and returns them as ordinary JavaScript objects
New ENCRYPT() and DECRYPT() SQL keywords that you can mix in when using Dojo SQL, to get transparent cryptography for columns of data. Cryptography is done on a Google Worker Pool thread, so that the browser UI is responsive.
Integration with the rest of Dojo, such as the Dojo Event system

TechTLV : Can you hear me now? The operator-centric mobile model is over
Can you hear me now? The operator-centric mobile model is over
Last week, T-Mobile Germany made some waves by banning Skype for the iPhone. Some might read this as a long overdue reassertion of operator power, but I disagree. A few months ago, I learned from a reliable source that a major operator was deliberately not shipping a very popular mobile phone model that they knew their customers wanted because the phone didn’t give them enough control over what the customer does. The phone was too open. This is exactly what Google was talking about back in 2007 when it insisted on openness as a condition to bidding in the FCC’s spectrum auction.
Ten years ago, when I covered mobile operators on Wall Street, they used to cite their vast capital expenditure on building on their cellular networks as their core differentiator. This was the reality behind Verizon’s amusing “can you hear me now?” campaign.
