A Dutch schoolteacher with no formal training in astronomy, Ms. van Arkel had joined tens of thousands of other Web volunteers to help classify photographs taken by deep-space telescopes. Stumped by the unusual image on her computer screen, she e-mailed the project staff for guidance. Staff members were stumped, too. And thus was christened the celestial body now known to astronomers worldwide as Hanny's Voorwerp (Dutch for "object"). Stories like Ms. van Arkel's are becoming more common, as the Internet opens up new opportunities for so-called citizen scientists. And as millions of people get involved in these participatory projects, scientists are grappling with how best to harness the amateurs' enthusiasm.

Facebook may have found a way to break the Egyptian government's blockade of its website. The government there has been blocking several social media sites that demonstrators are using to organize and document protests. Today marks the third day of protests in Egypt calling for the ouster of long-time President Hosni Mubarak. Facebook is using lessons it learned in Tunisia, where the government allegedly hacked its Web site and tried to steal the passwords and personal information of protesters in that country. Jillian York of Harvard's Berkman Center for Internet and Society monitors the Arab world online and discusses efforts to get around governments' blockades of social media sites.

Tor is free software and an open network that helps you defend against a form of network surveillance that threatens personal freedom and privacy, confidential business activities and relationships, and state security known as traffic analysis. Tor protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, and it prevents the sites you visit from learning your physical location. Tor works with many of your existing applications, including web browsers, instant messaging clients, remote login, and other applications based on the TCP protocol. Hundreds of thousands of people around the world use Tor for a wide variety of reasons: journalists and bloggers, human rights workers, law enforcement officers, soldiers, corporations, citizens of repressive regimes, and just ordinary citizens. (Note: sometimes ITGS students need to be able to access sites that are sometimes blocked)

Over a single generation, the Web and digital media have remade nearly every aspect of modern culture, transforming the way we work, learn and connect in ways that we're only beginning to understand. FRONTLINE producer Rachel Dretzin (Growing Up Online) teams up with one of the leading thinkers of the digital age, Douglas Rushkoff (The Persuaders, Merchants of Cool), to continue to explore life on the virtual frontier. The film is the product of a unique collaboration with visitors to the Digital Nation Web site, who for the past year have been able to react to the work in progress and post their own stories online. Dretzin and her team report from the front lines of digital culture -- from love affairs blossoming in virtual worlds, to the thoroughly wired classrooms of the future, to military bases where the Air Force is fighting a new form of digital warfare. Along the way, they begin to map the critical ways that technology is transforming us -- and what we may be learning about ourselves in the process.
