+ - Photon-transistors exchange data between photons->

Submitted by gregor-e
gregor-e (136142) writes "Scientist from the Niels Bohr Institute at University of Copenhagen and from Harvard University have come up with a way for photons to exchange data. Normally, photons pass right by each other without interacting. What these guys have done is establish a means of transferring information from one photon to another by using a single atom intermediary. This provides a step toward practical quantum computation, by allowing the signals to be purely optical in nature."

+ - Amtrak Reservation System Fails Nationwide->

Submitted by

xrsblu writes "Amtrak's ARROW ticketing system has suffered an as-yet-unexplained nationwide failure, beginning Saturday afternoon and persisting through the time of this submission. Customers are unable to make reservations or purchase tickets online, via phone operator, or in person at a ticket window. Train status updates are also unavailable. Amtrak has not issued a press release and their website makes no mention of the system failure, until one attempts to make a reservation whereby a standard "system maintenance" error appears."

+ - Google revoking DRM permissions on bought videos! 1

DoofusOfDeath (636671) writes "A few months ago I purchased a great Discovery Channel video from Google's downloadable video service. Sure I can't media-shift it, but I was willing to trade away some fair-use rights so my kids could see the video. I paid cash, they give me the video. End of story, right?

Wrong. Today I got this email (see below). It just goes to show that with DRM, there's little limit to the evil that can be done to you:

Hello,

As a valued Google user, we're contacting you with some important information about the videos you've purchased or rented from Google Video. In an effort to improve all Google services, we will no longer offer the ability to buy or rent videos for download from Google Video, ending the DTO/DTR (download-to-own/rent) program. This change will be effective August 15, 2007.

To fully account for the video purchases you made before July 18, 2007, we are providing you with a Google Checkout bonus for $20. Your bonus expires in 60 days, and you can use it at the stores listed here: http://www.google.com/checkout/signupwelcome.html. The minimum purchase amount must be equal to or greater than your bonus amount, before shipping and tax.

After August 15, 2007, you will no longer be able to view your purchased or rented videos.

If you have further questions or requests, please do not hesitate to contact us. Thank you for your continued support.

Sincerely,

The Google Video Team

AT&T To Offer TV Over Phone Lines 303

Posted by Zonk
from the next-up-is-radio-via-peanut-butter dept.
ppadala writes "AT&T is upgrading their phone lines to offer video programmes over phone line. The service, called U-verse TV will be available in parts of Southern California communities initially. Channel lineups will be similar to traditional cable and dish offerings. AT&T is insisting that, 'This offering is on par with those of its cable rivals. But AT&T claims that it offers customers more for their money, including fast channel changing, video-on-demand, three set-top boxes, a digital video recorder, a picture-in-picture feature that allows viewers to surf channels without switching channels and an interactive program guide.'"
Privacy

+ - Identification through Reverse DNS?

Submitted by
An anonymous reader writes "I've recently noticed that the reverse DNS name given to my IP from my ISP contains my mac address. It seems to me that regardless of IP address/dhcp logs that this could serve as a permanent unique identifier for a person. How many other ISPs do this? Are we clearing our google cookies periodically for nothing? Is this a privacy hole that should be closed up? I can see the ISPs internally being able to recognize their clients uniquely, but to the rest of the Internet is it a security violation for people to be tracked by an unchanging hostname?"

The Force is what holds everything together. It has its dark side, and it has its light side. It's sort of like cosmic duct tape.
