The jQuery offline plugin provides an easy mechanism for retrieving JSON data from a remote server, and then caching it. Subsequent requests for the same URL will retrieve the data from the cache, rather than the remote server.

If the user is online, the plugin will transparently request new content from the remote server, firing the callback again if the content has changed. If the user is offline, the plugin will request the data from the remote server for the most recent request when the user comes back online.

jQuery Offline uses the HTML5 localStorage API for persistence. You can use the same API for browsers that do not support localStorage, jQuery Offline will simply fall back to making a request to the server each time. As a result jQuery.retrieveJSON is a portable way to make a request for JSON that should be cached if possible.

I was recently surprised to find out how little the topic of DOM extensions is covered on the web. What’s disturbing is that downsides of this seemingly useful practice don’t seem to be well known, except in certain secluded circles. The lack of information could well explain why there are scripts and libraries built today that still fall into this trap. I’d like to explain why extending DOM is generally a bad idea, by showing some of the problems associated with it. We’ll also look at possible alternatives to this harmful exercise.

Doloto is an AJAX application optimization tool, especially useful for large and complex Web 2.0 applications that contain a lot of code, such as Bing Maps, Hotmail, etc. Doloto analyzes AJAX application workloads and automatically performs code splitting of existing large Web 2.0 applications.
