Submission + - IBM creates first cheap, commercially viable, electronic-photonic integrated chi (extremetech.com)

An anonymous reader writes: After more than a decade of research, and a proof of concept in 2010, IBM Research has finally cracked silicon nanophotonics (or CMOS-integrated nanophotonics, CINP, to give its full name). IBM has become the first company to integrate electrical and optical components on the same chip, using a standard 90nm semiconductor process. These integrated, monolithic chips will allow for cheap chip-to-chip and computer-to-computer interconnects that are thousands of times faster than current state-of-the-art copper and optical networks. Where current interconnects are generally measured in gigabits per second, IBM’s new chip is already capable of shuttling data around at terabits per second, and should scale to peta- and exabit speeds.

Submission + - Australian police warn against using Apple Maps (techworld.com.au)

angry tapir writes: "Australian police are warning people not to rely on Apple's new mobile mapping application after several motorists ended up in a semi-arid national park where temperatures can reach 46C and there is no water supply. Police in the town of Mildura, Victoria, issued a statement saying they've responded to several drivers who became stranded in Murray Sunset National Park. Apple's Maps application, introduced in iOS 6, shows Mildura near part of the park when it is actually located about 70 km to the northeast, according to police. Some motorists have been stranded for a day without food or water, walking long distances through dangerous terrain to get phone reception, police said."

Comment Re:queue and charge for invalid takedown notices (Score 1) 196

It's a nice idea, but I see a couple problems:

1. The rights holders likely subcontract out the actual take-down notification services, perhaps more than one.

2. An infringing site today may be no longer infringing when the request is reviewed. That is, the site may change between the time the take-down request is generated and the time Google actually reviews it. How would Google know?

Submission + - After 60 years, a room-temperature maser (nature.com)

gbrumfiel writes: "Before there were lasers, there were masers: systems that amplified microwaves instead of light. Solid state masers are used in a variety of applications, including deep space communication, but they've never been as popular as lasers, in part because they have to be cooled to near absolute zero in order to work. Now a team of British physicists have built a room-temperature maser using some spare chemicals and a laser they bought off of E-Bay. The new device is 100 million times as powerful as existing masers and might revolutionize telecommunications."

Not entirely true. Some Facebook pages (like mine: http://facebook.com/lannocc), are publicly viewable to anyone (as long as you're logged in). I actually wish FB would remove the logged-in restriction so my page could be searched and accessed by any person or web spider.

However, your other idea about hosting your own personal data is something I like and have thought about frequently. I imagine a social web of providers where you can pick a storage provider (or provide your own) from a marketplace. Some would be free, probably ad-supported. Others might take a small payment but guarantee an encrypted store with options for key delegation in the event of death, etc.

Submission + - Caught on camera: quantum mechanics in action (gla.ac.uk)

hawkinspeter writes: Scientists at the University of Glasgow have captured images of ‘quantum entanglement’ on camera for the first time.

In quantum mechanics, entanglement is one of the bizarre behaviours exhibited by particles where the rules of classical physics are broken and seemingly impossible events are a reality.

Described by Einstein as ‘spooky action at a distance’, entanglement is the phenomenon whereby two particles act as one system even when separated by immense distances.

The entangled particles are in a superposition where their individual state isn’t known. However, as soon as one of them is measured or observed the other will take on a correlated state instantaneously, seemingly violating the speed of light.

Being able to exploit such behaviour would have major applications in communications encryption and could underpin the next generation of computer technology, known as quantum computation.

If properly designed, something like a Facebook page actually is cacheable. Once an entry is made the entry itself remains static unless there is an edit. The page is simply a feed of resources that are all may be cached individually. Imagine it's an XML document with many xlinks to other resources, optionally also embedded in the original request. This is how I would do it.
