The Atlantic's James Fallows has turned in an excellent piece on China's Great Firewall, the censorship system that controls the flow of information into and within China. There's some meaty technical detail here, but the kicker is the social and political impact of the firewall: simply by making it inconvenient to read certain sites, the Chinese government can keep politically charged issues from surfacing in the national discourse:
Thus Chinese authorities can easily do something that would be harder in most developed countries: physically monitor all traffic into or out of the country. They do so by installing at each of these few “international gateways” a device called a “tapper” or “network sniffer,” which can mirror every packet of data going in or out. This involves mirroring in both a figurative and a literal sense. “Mirroring” is the term for normal copying or backup operations, and in this case real though extremely small mirrors are employed. Information travels along fiber-optic cables as little pulses of light, and as these travel through the Chinese gateway routers, numerous tiny mirrors bounce reflections of them to a separate set of “Golden Shield” computers.Here the term’s creepiness is appropriate. As the other routers and servers (short for file servers, which are essentially very large-capacity computers) that make up the Internet do their best to get the packet where it’s supposed to go, China’s own surveillance computers are looking over the same information to see whether it should be stopped...
[I]t would also be wrong to ignore the cumulative effect of topics people are not allowed to discuss. “Whether or not Americans supported George W. Bush, they could not avoid learning about Abu Ghraib,” Rebecca MacÂKinnon says. In China, “the controls mean that whole topics inconvenient for the regime simply don’t exist in public discussion.” Most Chinese people remain wholly unaware of internationally noticed issues like, for instance, the controversy over the Three Gorges Dam.

China’s nightmarish “citizen scores” system uses your online activity, purchases, messages, and social graph to rate your creditworthiness and entitlement to services. One way your score can be plunged into negative territory is for a judge to declare you to be a bad person (mostly this happens to people said to have refused to pay […]
The current pre-clearance rules for Canadians being processed through US immigration at Canadian airports limit the powers of US immigration officials, preventing them from strip-searching Canadians (they can ask Canadian border guards to do it, but if the Canadian guards refuse, they’re out of luck) and giving Canadians the ability to turn around and leave […]
If you want to work in tech, but don’t have any desire to code web apps to help businesses sell things to other business, you might want to consider a career in cybersecurity. Judging from the apparent complete infiltration of Russian hackers in American cyberspace, it seems fair to speculate that there’s a major shortage of […]
All moms are different. But all moms like getting flowers on Mother’s Day, and that’s a fact (not, however a fact we can document in any fashion.) Instead of getting chewed out for forgetting to call her on the second Sunday of May, you can take care of it ahead of time with Teleflora’s flower […]
