Most people surf the web blithely unconcerned about whether their surfing habits can be tracked, or, perhaps, even used against them. A new project of the Electronic Frontier Foundation,
Panopticlick, will perform a free test on your browser to determine how "unique" it is. You'll be amazed at how much information about you and your system can be retrieved over the Web. Many will find that their browser can be traced directly to them, without any doubt as to the accessing computer. If your browser is unique in this sense, it might be time to work on making it less so.

All religions, arts and sciences are branches of the same tree. All these aspirations are directed toward ennobling man's life, lifting it from the sphere of mere physical existence and leading the individual towards freedom. - Albert Einstein
