Submission + - Blackjack Player Breaks the Bank at Atlantic City

Hugh Pickens writes writes: "Mark Bowden writes that blackjack player Don Johnson won nearly $6 million playing blackjack in one night, single-handedly decimating the monthly revenue of Atlantic City’s Tropicana casino after previously taking the Borgata for $5 million and Caesars for $4 million. How did Johnson do it? For one thing, Johnson is an extraordinarily skilled blackjack player. "“He plays perfect cards," says Tony Rodio. But that's not enough to beat the house edge. As good as Johnson is at playing cards, his advantage is that he's even better at playing the casinos. When revenues slump as they have for the last five years at Atlantic City, casinos must rely more heavily on their most prized customers, the high rollers who wager huge amounts and are willing to lessen its edge for them primarily by offering discounts, or “loss rebates.” When a casino offers a discount of, say, 10 percent, that means if the player loses $100,000 at the blackjack table, he has to pay only $90,000. Two years ago the casinos started getting desperate and offered Johnson a 20 per cent discount. They also offered playing with a hand-shuffled six-deck shoe; the right to split and double down on up to four hands at once; and a “soft 17" whittling the house edge down to one-fourth of 1 percent so in effect, Johnson was playing a 50-50 game against the house, and with the discount, he was risking only 80 cents of every dollar he played. Johnson had to pony up $1 million of his own money to start, but, as he would say later: “You’d never lose the million. If you got to [$500,000 in losses], you would stop and take your 20 percent discount. You’d owe them only $400,000.”"

Submission + - Nvidia's Fermi GPU architecture makes its debut (techreport.com)

crookedvulture writes: Fermi is here. Nvidia has lifted the curtain on reviews of its latest GPU architecture, which will be available first in the high-end GeForce GTX 680 graphics card. The underlying GK104 processor is much smaller than the equivalent AMD GPU, with fewer transistors, a narrower path to memory, and greatly simplified control logic that relies more heavily on Nvidia's compiler software. Despite the modest chip, Nvidia's new architecture is efficient enough that The Tech Report, PC Perspective, and AnandTech all found the GeForce GTX 680's gaming performance to be largely comparable to AMD's fastest Radeon, which costs $50 more. The GTX 680 also offers other notable perks, like a PCI Express 3.0 interface, dynamic clock scaling, new video encoding tech, and a smarter vsync mechanism. It's rather power-efficient, too, but the decision to focus on graphics workloads means the chip won't be as good a fit for Nvidia's compute-centric Tesla products. A bigger GPU based on the Kepler architecture is expected to serve that market.

Submission + - Millions in China Live in Energy Efficient Caves

Hugh Pickens writes writes: "Barbara Demick reports in the LA Times that more than 30 million Chinese people live in caves, many of them in Shaanxi province where the Loess plateau, with its distinctive cliffs of yellow, porous soil, makes digging easy and cave dwelling a reasonable option. The better caves protrude from mountains and are reinforced with brick masonry and some are connected laterally so a family can have several chambers. Electricity and even running water can be brought in. "Most aren't so fancy, but I've seen some really beautiful caves: high ceilings and spacious with a nice yard out front where you can exercise and sit in the sun," says Ren, who works as a driver in the Shaanxi provincial capital, Xian. "It's cool in the summer and warm in the winter. It's quiet and safe." In recent years, architects have been reappraising the cave in environmental terms, and they like what they see. "It is energy efficient. The farmers can save their arable land for planting if they build their houses in the slope. It doesn't take much money or skill to build," says Liu Jiaping, director of the Green Architecture Research Center in Xian and perhaps the leading expert on cave living. Liu helped design and develop a modernized version of traditional cave dwellings that in 2006 was a finalist for a World Habitat Award, sponsored by a British foundation dedicated to sustainable housing. Meanwhile a thriving market around Yanan means a cave with three rooms and a bathroom (a total of 750 square feet) can be advertised for sale at $46,000. "Life is easy and comfortable here. I don't need to climb stairs. I have everything I need," says 76-year-old Ma Liangshui. "I've lived all my life in caves, and I can't imagine anything different.""

Submission + - 15% of the internet routed through China in April (washingtontimes.com)

olsmeister writes: For 18 minutes this past April, 15% of the world's internet traffic was routed through servers in China. This includes traffic from both .gov and .mil US TLD's. Is this related to the recent hacking of gmail accounts that appear to have originated in China? Probably not ... but the moral of the story is, if you're sending sensitive information across the net, make sure it is encrypted.

Australian Politician Caught Viewing Porn 150

destinyland writes "An Australian Parliament member has resigned after admitting he'd used government computers to access porn and gambling sites. McLeay 'gave an uncomfortable press conference outside Parliament House,' notes one technology site, 'during which he admitted he had acted in a standard not expected of cabinet ministers.' Paul McLeay was also the Minister for Mineral and Forest Resources as well as the Minister for Ports and Waterways. In resigning, he apologized to his constituents and parliamentary colleagues, as well as to his wife and family."

Submission + - Facebook bug could give spammers names, photos (idg.com.au)

angry tapir writes: "Facebook is scrambling to fix a bug in its website that could be misused by spammers to harvest user names and photographs. It turns out that if someone enters the e-mail address of a Facebook user along with the wrong password, Facebook returns a special "Please re-enter your password" page, which includes the Facebook photo and full name of the person associated with the address. A spammer with an e-mail list could write a script that enters the e-mail addresses into Facebook and then logs the real names. This could help make a phishing attack more realistic."

The Case Against Net Neutrality 702

jeek writes "While I certainly don't agree with it, this article tries to make the case that Net Neutrality may actually be bad for America. From the article: 'If the government regulates net neutrality, policies for internet access are set by one entity: the FCC. However, if the government stays out, each company will set its own policies. If you don’t like the FCC’s policies, you are stuck with them unless you leave the United States. If you don’t like your internet service provider’s policies, you can simply switch to another one. So which model sounds better to you?'"

Submission + - Obama Wants Allies To Go After Wikileaks (thedailybeast.com) 1

krou writes: Coming on the back of human rights groups criticising Wikileaks, American officials are saying that the Obama administration is pressuring allies such as Australia, Britain, and Germany to open criminal investigations against Wikileaks founder Julian Assange, and to try limit his ability to travel. 'It’s not just our troops that are put in jeopardy by this leaking. It’s U.K. troops, it’s German troops, it’s Australian troops—all of the NATO troops and foreign forces working together in Afghanistan,' said one American diplomatic official, who added that other governments should 'review whether the actions of WikiLeaks could constitute crimes under their own national-security laws.'

Submission + - Screw It, You're Dead Anyway (discovery.com) 1

disco_tracy writes: A California inventor has filed a patent for a coffin that screws into the ground vertically. The reason? It greatly reduce excavation labor and burial costs, decreases land use, and opens up more space for burials in unused areas of a cemetery. Writer Clark Boyd also lists 5 other unconventional burial options, including lye, ecopods, GPS devices that track bodies buried without headstones, cryogenics and — my favorite — getting buried in the sky.

sciencehabit writes: Modern physics can get complicated. Sure, researchers know exactly what forces act on a ball rolling down an incline—an experiment that helped Galileo develop universal laws for movement and acceleration. But what happens when a deformable shape like a rubber band rolls around? A new study reveals that the faster it goes, the more squashed it gets. (Video included)

Submission + - What to do with an old G5 Tower?

lunatic1969 writes: I've got an old G5 PowerPC tower that's sitting in a spare room not seeing much in the way of use. I'd like to stick a linux distribution on it and maybe breath some life back into it. I've got a few vague ideas. It might be a handy file server, streaming video for a security system, or simply just to have a spare box around. My question is therefore in two parts: First, are there any particularly creative projects or ideas anyone has for an old G5, and second and most important, which distribution currently offers the best support for this box?

Submission + - Wireless PCIe to enable remote graphics cards (techreport.com) 1

J. Dzhugashvili writes: If you read Slashdot, odds are you already know about WiGig and the 7Gbps wireless networking it promises. The people at Atheros and Wilocity are now working on an interesting application for the spec: wireless PCI Express. In a nutshell, wPCIe enables a PCI Express switch with local and remote components linked by a 60GHz connection. The first applications, which will start sampling next year, will let you connect your laptop to a base station with all kinds of storage controllers, networking controllers, and yes, an external graphics processor. wPCIe works transparently to the operating system, which only sees additional devices connected over PCI Express. And as icing on the cake, wPCie controllers will lets you connect to standard Wi-Fi networks, too.

Submission + - SSDs clash with hard drives in value comparison (techreport.com)

EconolineCrush writes: SSDs hardly offer compelling value on the cost-per-gigabyte scale. But what if one considers performance per dollar? This article takes a closer look at the value proposition offered by today's most common SSDs, mixing raw performance data with each drive's cost, both per gigabyte and as a component of a complete system. An even dozen SSD configurations are compared, and results from a collection of mechanical hard drives provides additional context. The data are laid out in detailed scatter plots that clearly illustrate the most favorable intersections of price and performance, and you might be surprised to see just how well the SSDs fare versus traditional hard drives. A few of the SSDs offer much better value than their solid-state competition, too.
