Recently, I have been playing around with lots of interesting technologies. I will use this writing to describe some interesting concepts, and also share with the world my favorite bookmarks and my web files.
The best of all, they are all FREE. Here is the list:

1) http://www.loki.com GPS locator: My favorite Firefox plug-in, a virtual-GPS locator using nearby wireless access point to triangulate and identify one’s location.

2) http://del.icio.us Online Social Bookmark: Ever wonder what the world is bookmarking? This utility shows that by leveraging social network and also allows one to tag and create online bookmarks to share with others.
3) http://www.frucall.com Smart Shopper. While shopping in the store, ever wonder what price the same product costs online? Now one can call this phone number 1-888-DO-FRUCALL (1-888-363-7822), enter the product bar code number, and hear an automated voice response of the same product’s online price comparison.
