If you find yourself in China or some other country that puts up firewalls blocking access to web sites that offer views which governments don't want you to know then check out which tools a recent Harvard study found are the best to use to get around internet censorship attempts.

Ten tools--some commercial products and some open-source, nonprofit efforts--were tested for the new study, which was conducted partly in a lab setting at Harvard and partly in cybercafes in Beijing, Shanghai, Hanoi, and Seoul. Hal Roberts, a senior researcher at Berkman, visited the cafes and ran the circumvention tools through their paces. The best tools overall were found to be Ultrareach, Psiphon, and Tor, while Dynaweb and Anonymizer also scored well. Others suffered greater problems with usability or security.

Load up your laptop before international travel so you can get thru to your favorite sites from cyber cafes.
