China Mobile begins TD-LTE trials in Guangzhou and Shenzhen, users need a Galaxy S III for now

It looks like China Mobile is making good on its promise to carry out TD-LTE trials this year: the carrier is launching test programs in both Guangzhou and Shenzen, according to a report from the Chinese news site Guangming Online. As it happens, this isn't technically the first time China Mobile has invited users to test its LTE network, but it is the first time people can access it via smartphones (as opposed to routers and MiFi devices).

Curiously, the trial will initially work only on the TD-LTE-capable Galaxy S III, which is strange because China Mobile just unveiled a handful of LTE handsets at MWC, and didn't even mention the GSIII at its press conference. Once you've got that phone in hand, you'll need to preload it with 4,699 yuan worth of credits and sign a two-year agreement, with 388 yuan to be deducted each month. Already signed up for 2G or 3G service with China Mobile? You can add 1,500 yuan to receive a 4G device, USIM card and 15 gigs of LTE data (free for the first three months).

Shifting sands: Force is the key to granular state-shifting

Feb. 15, 2013 ? Ever wonder why sand can both run through an hourglass like a liquid and be solid enough to support buildings? It's because granular materials -- like sand or dirt -- can change their behavior, or state. Researchers from North Carolina State University have found that the forces individual grains exert on one another are what most affect that transition.

Physicists have explored the changing behavior of granular materials by comparing it to what happens in thermodynamic systems. In a thermodynamic system, you can change the state of a material -- like water -- from a liquid to a gas by adding energy (heat) to the system. One of the most fundamental and important observations about temperature, however, is that it has the ability to equilibrate: a hot cup of tea eventually cools to match the temperature of the room.

Physicists thought they could use thermodynamics' underlying ideas to explain the changes in granular materials, but didn't know whether granular materials had properties which might equilibrate in a similar way. In other words, instead of temperature being the change agent in a granular system, it might be a property related to the amount of free space, or the forces on the particles. But no one had really tested which of the two might exhibit this property of equilibration.

NC State physicist Karen Daniels and former graduate student James Puckett devised a way to do just that. Puckett used two different types of plastic "granules" with different properties that floated atop a layer of air on a small table. Puckett and Daniels wanted to see what would bring the two types of particles into equilibrium with one another. In order to make their measurements, they used a plastic material that indicated a change in force by a change in brightness.

First, they measured compactivity, which describes the number of ways particles can arrange themselves inside a given space, or volume, by reducing the physical space around the granules, but the two types of particles failed to achieve equilibrium. When they measured the ways that the forces between the particles could rearrange, they saw the equilibrium they were looking for.

Their findings appear in Physical Review Letters.

"Physicists often have ideas that are theoretically elegant, such as the idea that there might be new temperature-like variables to be discovered, and then it's exciting to go into the lab and see how well these ideas work in practice," says Daniels. "In this case, we found it is possible to take the temperature of a granular system and find out more about what makes it change its state. The 'thermometer' for this temperature is actually the particles themselves."

[News] Bugs & Fixes: iPhone fails to pair to Bluetooth device

Last September, a new thread in Apple Support Communities briefly noted that a user was unable to get his iPhone 5 to pair with other Bluetooth devices. As it turned out, he was not alone. Cut to the present: this thread is now 29 pages long, with several hundred confirmations of the symptom.

Here's the problem: In the most common scenario, users are unable to pair an iPhone 5 to a Bluetooth car audio system. In some other cases, users are unable to pair an iPhone 5 to a Bluetooth headset. Pairings to other devices may or may not work. Typically, problems begin after upgrading from an older iPhone model (which was working just fine) to an iPhone 5, running iOS 6. In a few instances, the same sort of pairing problems have been reported for the iPhone 4S.

If this has happened to you, one or more of the following fixes should get you connected again:

Update the car audio firmware: Several postings in the above Communities thread cite confirmations from automobile manufacturers that their cars' audio systems are "not compatible with iPhone 5." In particular, the older Bluetooth drivers in these systems are not compatible with the Bluetooth 4.0 standard used by the latest iPhones. A firmware update to the audio system eliminates the problem. Check with the manufacturer of your car or audio system for details.

Apple has confirmed that some car audio systems require a firmware update to work with AVRCP 1.4 Bluetooth. However, the symptoms described in the Apple article refer only to an inability to perform certain music playing functions--not an inability to pair devices. So I doubt this is a cause of the problems described in the Communities thread.

Follow the instructions: Several users were able to pair their new iPhone to their car's audio system only after they made sure to precisely follow instructions. In particular, pairing required a confirming action from both the iPhone and the car audio system. Users, apparently having forgotten how they originally paired their older iPhone model, were erroneously attempting to pair their new iPhone 5 by confirming only on one device. Similarly, when attempting to pair an iPhone to a Bluetooth headset, some users didn't realize that it was necessary to hold down the headset's call button.

In other words, RTFM. If you can no longer locate the manual for your device, check the thread cited above. Numerous posts offer step-by-step instructions for how to pair different devices to an iPhone.

Modify iPhone Settings: A number of users had success by making a change in the iPhone's Settings app. Specifically, navigate to General > Accessibility > Physical & Motor. From here, change the Incoming Calls setting from Default to Headset. This change ensures that the iPhone creates a Bluetooth headset pairing to your car's audio system, which is needed for phone calls to work as expected. When you are not in your car, the iPhone reverts to its "normal" behavior.

Clear the device's memory: A few users claimed that, when trying to pair an iPhone 5 to their car's audio system, the system would instead continue to attempt to connect with a previously paired, now absent, iPhone model. To fix this, wipe the car system's memory clean, having it "forget" all previously paired devices. After doing so, pairing with the new iPhone should succeed.

Update to iOS 6.1: In some cases, the culprit may be a bug in the iOS 6.0 software. At least for Honda CR-V owners, upgrading to iOS 6.1 seemed to eliminate Bluetooth pairing problems.

Consider the hardware: As it happens, my wife's iPhone 4 fell victim to an intermittent Bluetooth failure. About half the time, the phone would successfully pair with the aftermarket Sony Bluetooth audio system in her car. At the other times, the iPhone would fail to pair. None of the above suggested solutions had any effect. What did work was dumping the iPhone 4 and moving up to an iPhone 4S. In this case, I suspect there was a Bluetooth hardware failure in the iPhone 4.

World's largest trove of tiny cars goes to auction

Robert Frank, CNBC ? ? ? 8 hrs.

Like many of the wealthy, Bruce Weiner likes to collect things.

The candy entrepreneur who made his fortune from Double Bubble and Razzles gum, wax lips and other confections collects radios, watches, vintage motorcycles and Volkswagens.

But his real passion in recent years has been collecting small cars. Very small cars. Over 11 years, Weiner has built the world's largest collection of "microcars" ? three- and four-wheeled cars made after World War II that are the early predecessors of today's increasingly popular Smart cars, MINI Coopers and Fiat 500s.

Today and tomorrow, Weiner and RM Auctions will be selling off the collection of more than 200 cars and 300 car-related collectibles. The collection is expected to fetch more than $6 million.

Weiner said he's selling the collection as part of a broader downsizing of his lifestyle and desire to share the cars with others after spending years hunting them down.

"I'm 54 and I'm starting to simplify," he said. "I don't want my stuff to own me. "

He said that it took 11 years to build the collection. While microcars have always been the poor cousin to vintage muscle cars and exotics, they have a cult following among collectors. Many microcars were built in Europe and Asian after World War II, when money, gasoline and raw materials were scarce. In many countries, cars with three wheels didn't require a driver's license, making them more attractive.

"They are very rare," Weiner said. "And they're part of history."

Weiner said much of the joy of building the collection was "the thrill of the hunt."

Take, for example, his ordeal in buying the 1955 Kroboth Allwetter-Roller, a three-wheel convertible designed by car-design legend Gustav Korboth. Weiner heard that a prized example of the car was owned by an older man in Bavaria. Weiner traveled to the man's house every three months for three years, but the seller adamantly refused.

"He chased me off the property every time," he said. "He either met me with a shot gun or German shepherds."

Eventually, the owner died and Weiner befriended the man's sister and brother, and convinced them to sell. The car could sell for $40,000 to $50,000 (there are no reserves in the sale).

Among the most valuable cars to be sold in the auction is a 1958 F.M.R. Tg 500 "Tiger," which could sell for more than $150,000. A modified 1959 BMW Isetta, called "Whatta Drag," could fetch $100,000. The car was commissioned by Weiner to look like a famous Hot Wheels drag-racer. It's only one of four Hot Wheels to be turned into real cars.

The smallest production car ever built will also be sold. The 1964 Peel P50 could sell for $35,000 to $40,000. The sales slogan for the three-wheeler used to be "Almost cheaper than walking!" Apparently, not anymore.

David Plouffe: "Bigger Problem [GOP Has] Got With Latinos Isn?t Immigration. It?s Their Economic Policies ..."

Robert Draper writes a long article in the New York Times called "Can the Republicans Be Saved from?Obsolescence?" that mostly consists of younger GOP operatives like Patrick Ruffini explaining how they aren't to blame for the Romney Campaign and how they would have been awesome if anybody had hired them, what with their digital wizardry and all.

I presume there's a good story out there somewhere about the Romney campaign and its multitudinous consultants that would involve the terms "conflict of interest" and "financial malfeasance," but this isn't it.?

However, when you finally get to p. 8, there's an interview with David Plouffe, manager of the 2008 Obama campaign and who just retired from being Senior Adviser to the President to go make money. Plouffe, who has just about the best track record in American politics of knowing what he's talking about when it comes to winning elections, points out that everything you've read since the election is wrong:

But, I asked Plouffe, wasn?t the G.O.P. just one postmodern presidential candidate ? say, a Senator Marco Rubio ? away from getting back into the game??

Pouncing, he replied: ?Let me tell you something. The Hispanic voters in Nevada, Colorado and New Mexico don?t give a damn about Marco Rubio, the Tea Party Cuban-American from Florida. You know what? We won the Cuban vote! And it?s because younger Cubans are behaving differently than their parents. It?s probably my favorite stat of the whole campaign. So this notion that Marco Rubio is going to heal their problems ? it?s not even sophomoric; it?s juvenile! And by the way: the bigger problem they?ve got with Latinos isn?t immigration. It?s their economic policies and health care. The group that supported the president?s health care bill the most? Latinos.?

All this Rubio / "path to citizenship" talk, it's just a Democratic honey trap to lure Republicans in to their destruction. Ask Plouffe.
