As one whose music collection may be sorely lacking in danceable tunes, I couldn't see myself dropping $350 on the Rolly. It goes on sale in Japan on September 29 for equivalent of about $353 U.S. The gadget is small enough to fit in your hand and comes standard with 1GB of internal memory (some 500 songs, though programing the Rolly with more complex dance moves will diminish that capacity), stereo speakers, and a five hour battery life. Users can even program the Rolly's moves themselves.

In addition to playing back music from its internal memory the Rolly can also receive music streamed via a Bluetooth connection.Īs far as I'm concerned the best part of the Rolly is its reported ability to analyze music and come up with the dance moves. In addition to history sniffing, the UC San Diego researchers also looked at how major sites such as YouTube and The Huffington Post use scripts to track your mouse pointer movements. Firefox users could also disable CSS visited links by modifying the browser's about:config file. If you want to make sure you are completely protected, you could also use the Firefox browser add-on NoScript that prevents sites from running JavaScript in your browser. Internet Explorer may also defend against this attack if you use the browser in private browsing mode. Many modern browsers, including Google Chrome, Apple Safari, and Mozilla Firefox are able to defend against history sniffing. If you don't want your history sniffed or hijacked, there are several things you can do. There's no question, however, that having a Website target you in such a specific way can, as Google CEO Eric Schmidt might say, "cross the creepy line." Or displaying mapping services you are more likely to use, such as Google Maps or Map Quest when you click a "show map" link.
Other uses include targeting you with your favorite blog aggregation service such as Google Reader and Netvibes, instead of showing you every RSS reader link on the planet. Blogger and Web developer Niall Kennedy points out that you can use history sniffing to determine which social networking sites you visit and show you "share" or "like" buttons only for those specific sites. One possibility could be building a profile about you based on your browsing history and other information collected by the site.īut there are also more benign uses of history sniffing that can actually make your browsing experience better, some Web developers argue. History-Sniffing ImplicationsIt's easy to get carried away with the fear that your browsing history could be used for some nefarious purpose. The researchers even say that some Web analytics companies such as Tealium and Beencounter provide history-sniffing services to their clients. History sniffing is nothing new, but the UC San Diego study shows just how prevalent this exploit is. , an amateur porn site and one of the 100 most visited sites on the Web, analyzes your browsing history for more than 21 sites, according to the researchers. About 18 of the offending 46 sites, such as, , and, are using the exploit to analyze your past visits to more than 220 sites.
Reading over the researcher's findings, it's amazing to see how many hidden links are used by each site. The majority of sites, according to the UC San Diego researchers, are only inspecting the style properties and nothing more. The researchers also found that another 17 sites for a total of 63 are transferring your browsing history to their network, but couldn't confirm the sites were using the information collected. Although the researchers found 485 sites are exploiting the history-sniffing flaw, 46 of those sites are actively downloading your browser history.
