Here are a few miscellaneous tech bits you may want to try out this weekend!
Gina Trapani on Lifehacker says:
As a prolific netizen, you generate lots of web-based feeds: your Flickr photos, your del.icio.us bookmarks, your weblog posts and your Lifehacker comments, to name a few. Instead of going here, there and everywhere to see all the content you create on the web, combine it all into one master feed using with the newly-launched Yahoo! Pipes.

And by the way, you can download many other gadgets to run on this, or even create your own! Microsoft has taken the idea of Widgets a bit further pretty nicely this time!
Chris Double put up an example of using Zimbra (a web based email/calendar system with heavy AJAX use) offline. He says:
Zimbra is heavily ajax based and gives a good idea of how difficult or easy it is to convert an existing application to use the offline support. For this first cut I made Zimbra work when the browser is in offline mode and provide the ability to browse the email folders, and view messages while offline that are held in the Inbox and Drafts folders.
He used DOM Storage, Jar file protocol and Offline events to achieve the feat. He even has a nice screencast showing the stuff. This is quite neat, since occasionally connected model of computing is very much going to be mainstream in the next few years.
