'Wash Me' taken to a new level - the Dust Art of Scott Wade
Topic: Miscellaneous 11:57 am EDT, Jul 26, 2006

As a kid there was nothing like dragging your finger across the dirty back window of your mom's minivan. Imagine lifting your finger to find you've created a Mona Lisa on the rear glass. Scott Wade of San Marcos, TX is perhaps the only person who could say he's done this.

State Agency Uses Patriot Act to get Facebook info
Topic: Miscellaneous 2:27 pm EDT, Jul 19, 2006

From Slashdot:

"An article from the National Association of Colleges and Employers contains yet another horror story about a prospective hire's Facebook being checked — with a different twist. The interviewee had enabled privacy on his profile, '[b]ut, during the interview, something he was not prepared for happened. The interviewer began asking specific questions about the content on his Facebook.com listing and the situation became very awkward and uncomfortable. The son had thought only those he allowed to access his profile would be able to do so. But, the interviewer explained that as a state agency, recruiters accessed his Facebook account under the auspices of the Patriot Act.' How can a 'state agency' use the Patriot Act to subpoena a Facebook profile?"

What he said... how?

Ignoring the Great Firewall of China
Topic: Miscellaneous 4:31 pm EDT, Jun 27, 2006

We've all heard of the Great Firewall of China. These guys found a clever way around it:

The Great Firewall of China is an important tool for the Chinese Government in their efforts to censor the Internet. It works, in part, by inspecting web traffic to determine whether or not particular words are present.
...
It turns out [caveat: in the specific cases we’ve closely examined, YMMV] that the keyword detection is not actually being done in large routers on the borders of the Chinese networks, but in nearby subsidiary machines. When these machines detect the keyword, they do not actually prevent the packet containing the keyword from passing through the main router (this would be horribly complicated to achieve and still allow the router to run at the necessary speed). Instead, these subsiduary machines generate a series of TCP reset packets, which are sent to each end of the connection. When the resets arrive, the end-points assume they are genuine requests from the other end to close the connection — and obey. Hence the censorship occurs.

However, because the original packets are passed through the firewall unscathed, if both of the endpoints were to completely ignore the firewall’s reset packets, then the connection will proceed unhindered! We’ve done some real experiments on this — and it works just fine!! Think of it as the Harry Potter approach to the Great Firewall — just shut your eyes and walk onto Platform 9¾.
