Tesla switched on the world's biggest lithium ion battery on Friday in time to feed Australia's shaky power grid for the first day of summer, meeting a promise by Elon Musk to build it in 100 days or give it free. From a report: "South Australia is now leading the world in dispatchable renewable energy," state Premier Jay Weatherill said at the official launch at the Hornsdale wind farm, owned by private French firm Neoen. Tesla won a bid in July to build the 129-megawatt hour battery for South Australia, which expanded in wind power far quicker than the rest of the country, but has suffered a string of blackouts over the past 18 months. In a politically charged debate, opponents of the state's renewables push have argued that the battery is a "Hollywood solution" in a country that still relies on fossil fuels, mainly coal, for two-thirds of its electricity.

The video takes the viewer to the "Ground Zero" of climate change. Throughout the 7-minute long video, the viewer can interactively look around the locations visited. Voice narration and various scientists featured in the video explain what is happening in the Arctic, what causes the melting, and what the potential consequences are for the world.

According a report from Defense One, a United Nations meeting in Geneva earlier this month on lethal autonomous weapons systems (LAWS) was derailed when Russia said they would not adhere to any prohibitions on killer robots. "The U.N. meeting appeared to be undermined both by Russia's disinterest in it and the framework of the meeting itself," reports International Business Times. "Member nations attempted to come in and define what LAWS' systems would be, and what restrictions could be developed around autonomous war machines, but no progress was made." From the report: In a statement, Russia said that the lack of already developed war machines makes coming up with prohibitions on such machines difficult. "According to the Russian Federation, the lack of working samples of such weapons systems remains the main problem in the discussion on LAWS... this can hardly be considered as an argument for taking preventive prohibitive or restrictive measures against LAWS being a by far more complex and wide class of weapons of which the current understanding of humankind is rather approximate," read the statement.

An anonymous reader quotes a report from CNNMoney: The McKinsey Global Institute cautions that as many as 375 million workers will need to switch occupational categories by 2030 due to automation. The work most at risk of automation includes physical jobs in predictable environments, such as operating machinery or preparing fast food. Data collection and processing is also in the crosshairs, with implications for mortgage origination, paralegals, accounts and back-office processing. To remain viable, workers must embrace retraining in different fields. But governments and companies will need to help smooth what could be a rocky transition.

Despite the looming challenges, the report revealed how workers can move forward. While the introduction of the personal computer in the 1980s eliminated some jobs, it created many more roles. Workers who are willing to develop new skills should be able to find new jobs. The authors don't expect automation will displace jobs involving managing people, social interactions or applying expertise. Gardeners, plumbers, child and elder-care workers are among those facing less risk from automation. The report says that 39 million to 73 million jobs in the U.S. could be destroyed, but about 20 million of those displaced workers can be shifted fairly easily into similar occupations. Globally, up to 800 million workers could be displaced.

Two teams of researchers have published papers [1, 2] in the journal Nature detailing how they were able to create unprecedented quantum simulators consisting of over 50 qubits. The University of Maryland team and National Institute of Standards and Technology team -- the two teams behind one of the two new papers -- were able to create a quantum simulator with 53 qubits. Motherboard reports: Quantum simulators are a special type of quantum computer that uses qubits to simulate complex interactions between particles. Qubits are the informational medium of quantum computers, analogous to a bit in an ordinary computer. Yet rather than existing as a 1 or 0, as is the case in a conventional bit, a qubit can exist in some superposition of both of these states at the same time. For the Maryland experiment, each of the qubits was a laser cooled ytterbium ion. Each ion had the same electrical charge, so they repelled one another when placed in close proximity. The system created by Monroe and his colleagues used an electric field to force the repelled ions into neat rows. At this point, lasers are used to manipulate all the ytterbium qubits into the same initial state. Then another set of lasers is used to manipulate the qubits so that they act like atomic magnets, where each ion has a north and south pole. The qubits either orient themselves with their neighboring ions to form a ferromagnet, where their magnetic fields are aligned, or at random. By changing the strength of the laser beams that are manipulating the qubits, the researchers are able to program them to a desired state (in terms of magnetic alignment).

According to Zhexuan Gong, a physicist at the University of Maryland, the 53 qubits can be used to simulate over a quadrillion different magnetic configurations of the qubits, a number that doubles with each additional qubit added to the array. As these types of quantum simulators keep adding more qubits into the mix, they will be able to simulate ever more complex atomic interactions that are far beyond the capabilities of conventional supercomputers and usher in a new era of physics research. Another team from Harvard and Maryland also released a paper today in which it demonstrated a quantum simulator using 51 qubits.

Tesla's Model 3 has a confirmed range of 310 miles, according to the Environmental Protection Agency. "That figure applies to the long-range version of the Model 3, and echoes the vehicle specs released by Tesla back in July," reports The Verge. "It also makes the Model 3 one of the most efficient passenger electric vehicles on the market." From the report: The EPA's range is used as the advertised figure for electric vehicles that are sold in the US. The 310-mile range is an estimate of the number of miles the vehicle should be able to travel in combined city and highway driving from a full charge. That's 131 miles per gallon gasoline equivalent (MPGe) for city driving, 120 MPGe on the highway, and 126 MPGe combined. You'll have to pay more to get that extended range, though. Tesla said it would be selling a standard version of the Model 3, with just 220 miles of range, for $35,000. The long-range version will start at $44,000, the automaker says. Production on the standard version isn't expected to begin until 2018.

Heart44 writes: A number of outlets are reporting a Samsung laboratory breakthrough allowing smaller and faster charging lithium-ion batteries using three-dimensional graphene. Digital Trends reports: "Scientists created a 'graphene ball' coating for use inside a regular li-ion cell, which has the effect of increasing the overall capacity by up to 45 percent and speeding up charging by five times. If your phone charges up in 90 minutes now, that number will tumble to just 18 minutes if the cell inside has been given a graphene ball boost. What's more, this doesn't seem to affect the cell's lifespan, with the team claiming that after 500 cycles, the enhanced battery still had a 78 percent charge retention. The graphene coating improves the stability and conductivity of the battery's cathode and electrode, so it's able to take the rigors of fast charging with fewer downsides." The technical paper describing how the graphene ball works and how it's produced is published in the journal Nature.

dmoberhaus writes: Someone claimed to use their Tesla to power a cryptocurrency mine to take advantage of the free energy given to Tesla owners. But even with free energy, does this scheme make sense? Motherboard ran the numbers.

From the report: "...If we assume that each of the GPUs in this rig draws around 150 watts, then the 16 GPUs have a total power draw of 2.4 kilowatts per hour or 57.6 kilowatt hours per day if they ran for a full 24 hours. According to Green Car Reports, a Tesla Model S gets about 3 miles per kilowatt hour, meaning that running this mining rig for a full day is the equivalent of driving nearly 173 miles in the Tesla. According to the Federal Highway Administration, the average American drives around 260 miles a week. In other words, running this cryptocurrency mine out of the trunk of a Tesla for a day and a half would use as much energy as driving that Tesla for a full week, on average. Moreover, drivers who are not a part of Tesla's unlimited free energy program are limited to 400 kilowatt hours of free electricity per year, meaning they could only run their rig for a little over 7 days on free energy.

Okay, but how about the cost? Let's assume that this person is mining Ethereum with their GPUs. Out of the box, an average GPU can do about 20 megahashes per second on the Ethereum network (that is, performing a math problem known as hashing 20 million times per second). This Tesla rig, then, would have a total hashrate of about 320 megahashes. According to the Cryptocompare profitability calculator, if the Tesla rig was used to mine Ethereum using free electricity, it would result in about .05 Ether per day -- equivalent to nearly $23, going by current prices at the time of writing. In a month, this would result in $675 in profit, or about the monthly lease for a Tesla Model S. So the Tesla would pay for itself, assuming the owner never drove it or used it for anything other than mining Ethereum, Ethereum doesn't drop in value below $450, and the Tesla owner gets all of their energy for free." Motherboard also notes that this conclusion "doesn't take into account the price of each of the mining rigs, which likely cost about $1,000 each, depending on the quality of the GPUs used." TL;DR: Mining cryptocurrency out of your electric car is not worth it.

Microsoft has reportedly finished testing out its Office apps on Chromebooks as a number of Chromebooks are now seeing the Office apps in the Google Play Store. Samsung's Chromebook Pro, Acer's Chromebook 15, and Acer's C771 have the Office apps available for download. The Verge reports: The apps are Android versions of Office which include the same features you'd find on an Android tablet running Office. Devices like Asus' Chromebook Flip (with a 10.1-inch display) will get free access to Office on Chrome OS, but larger devices will need a subscription. Microsoft has a rule across Windows, iOS, and Android hardware that means devices larger than 10.1 inches need an Office 365 subscription to unlock the ability to create, edit, or print documents.

An anonymous reader quotes a report from Quartz: Researchers at Harvard's Wyss Institute and MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) announced today (Nov. 27) that they've created robotic "muscles" that can lift up to 1,000 times their own weight. The simple objects are constructed out of metal or plastic "skeletons" that are covered in either a liquid or air, and then sealed in plastic or fabric "skins." The muscle pulls taught when a vacuum is created inside the skin, and goes slack when the vacuum is released. By folding the skeletons in different ways, the vacuum can pull the muscle in different directions. "Vacuum-based muscles have a lower risk of rupture, failure, and damage, and they don't expand when they're operating, so you can integrate them into closer-fitting robots on the human body," Daniel Vogt, a research engineer at the Wyss Institute, said in a release.

These new structures are also surprisingly cheap. As they don't require anything other than water or air to move them, the researchers told Harvard that a single muscle can be built in about 10 minutes, for less than $1. (Obviously, there'd still be a cost for the vacuum or whatever is being used to change the pressure of the muscles.)

Paul Lilly, writing for HotHardware: Looking at the release notes for the latest AIDA64 system diagnostics and benchmarking utility, there are several unannounced Intel processors on tap, including a mobile Core i9 processor and what appears to be a Coffee Lake refresh, due out sometime in 2018. Starting with mobile, it looks like Intel will be making an aggressive play in the laptop space with several new laptop chips, including at least one Core i9 processor with an unlocked multiplier. That is the Core i9-8950HK, a 6-core CPU with Hyper Threading support, 12MB of L3 cache, and a 45W TDP. Sitting below that are a handful of other mobile products, all based on Intel's Coffee Lake-H architecture. Two of them are Core i7 parts -- Core i7-8850H and Core i7-8750H, both of which are 6-core/12-thread processors with 12MB of L3 cache and a 45W TDP, same as the Core i9-8950H, but at presumably different clockspeeds and without an unlocked multiplier. The other two are the Core i5-8400H (6-core/6-thread, 9MB L3 cache, 45W TDP) and Core i3-8300H (4-core/4-thread, 8MB L3 cache, 45W TDP).

Vox reports on Amazon's recent push for "corporate sustainability": It plans to have 15 rooftop solar systems, with a total capacity of around 41 MW, deployed atop fulfillment centers by the end of this year, with plans to have 50 such systems installed by 2020. Amazon was the lead corporate purchaser of green energy in 2016. That year, it also announced its largest wind energy project to date, the 253 MW Amazon Wind Farm Texas. Overall, the company says, it has "announced or commenced construction on wind and solar projects that will generate a total of 3.6 million megawatt hours (MWh) of renewable energy annually."
But here's the most interesting part. GeekWire reports: Amazon is moving ahead with a unique plan to use heat generated from data centers in the nearby Westin Building to warm some of its new buildings downtown. The system transfers the heat from the data centers via water piped underground to the Amazon buildings. The water is then returned to the Westin Building once it's cooled down to help cool the data centers. The setup will be unusual. "Certainly there are other people using waste heat from server farms but you don't hear a lot about tying it in with buildings across the street from each other," said Seattle City Councilmember Mike O'Brien.

"Computer pioneer Geoff Tootill passed away in October," writes long-time Slashdot reader tigersha. Born in 1922, Tootill began his career troubleshooting airborne radar systems during World War II, leading him to some pioneering research in the late 1940s. "He worked on the first computer that stored a program in main memory, as opposed to a paper tape, and actually had the opportunity to teach Alan Turing and debug one of Turing's programs." The Guardian remembers: The computer could store just 32 instructions or numbers using a single cathode ray tube. The machine first worked in June 1948, taking 52 minutes to find the highest factor of 262,144, involving about 3.5 million arithmetic operations. The following year, Tootill transferred to Ferranti, the Manchester-based electrical engineering company, to specify a full-scale computer...the world's first commercially available computer.
That was the Ferranti Mark I, first released in 1951.

Tootill passed away at the age of 95.

schwit1 tells us that "Robby the Robot" -- a prop from the 1956 movie Forbidden Planet -- has just been auctioned for $5.3 million, making it the second most-expensive movie prop in history. New Atlas reports: The complete Robby suit, control panel, his jeep, numerous spares, alternate original "claw" hands, and the original wooden stage shipping crates, were sold Tuesday by Bonhams in New York for US $5,375,000 including buyers premium. The only purpose-built movie prop to have ever sold for more is Marilyn Monroe's "subway dress" from The Seven Year Itch (1955) which was sold by Profiles in History for $5,520,000 (including buyers premium) in 2011.
After Forbidden Planet, Robby the Robot reappeared in a movie called The Invisible Boy, and later had a climactic showdown with the robot from Lost in Space. He also made appearances on other TV shows, including The Twilight Zone, Mork & Mindy, and The Many Loves of Dobie Gillis. And he even appeared in commercials, including one warning about the dangers of depleting the ozone layer -- plus a commercial for Charmin bathroom tissue.

Slashdot reader overheardinpdx shares a video from the SC17 supercomputing conference where Bruce Tulloch from BitScope "describes a low-cost Rasberry Pi cluster that Los Alamos National Lab is using to simulate large-scale supercomputers." Slashdot reader mspohr describes them as "five rack-mount Bitscope Cluster Modules, each with 150 Raspberry Pi boards with integrated network switches." With each of the 750 chips packing four cores, it offers a 3,000-core highly parallelizable platform that emulates an ARM-based supercomputer, allowing researchers to test development code without requiring a power-hungry machine at significant cost to the taxpayer. The full 750-node cluster, running 2-3 W per processor, runs at 1000W idle, 3000W at typical and 4000W at peak (with the switches) and is substantially cheaper, if also computationally a lot slower. After development using the Pi clusters, frameworks can then be ported to the larger scale supercomputers available at Los Alamos National Lab, such as Trinity and Crossroads.
BitScope's Tulloch points out the cluster is fully integrated with the network switching infrastructure at Los Alamos National Lab, and applauds the Raspberry Bi cluster as "affordable, scalable, highly parallel testbed for high-performance-computing system-software developers."

"Tesla's newest promises break the laws of batteries," writes Bloomberg. Long-time Slashdot reader rudy_wayne summarizes their report. "Elon Musk knows how to make promises. Even by his own standards, the promises made last week while introducing two new Tesla vehicles...are monuments of envelope pushing. To deliver, according to close observers of battery technology, Tesla would have to far exceed what is currently thought possible." The Tesla Semi, which Musk claims can haul 80,000 pounds at highway speeds for 500 miles, then recharge 400 miles of range in 30 minutes, would require "a charging system that's 10 times more powerful than one of the fastest battery-charging networks on the road today -- Tesla's own Superchargers."

The Tesla Roadster is promised to be the quickest production car ever built. But that achievement would mean squeezing into its tiny frame a battery twice as powerful as the largest battery currently available in any electric car. These claims are so far beyond current industry standards for electric vehicles that they would require either advances in battery technology or a new understanding of how batteries are put to use, said Sam Jaffe, battery analyst for Cairn Energy Research in Boulder, Colorado.
But Jaffe reaches an interesting conclusion. "I don't think they're lying. I just think they left something out of the public reveal that would have explained how these numbers work."

Slashdot reader AmiMoJo reports: Sharp's COCOROBO (heart-bot) vacuum cleaners can not just clean your house. They have cameras that can be viewed from a smart phone, and automatically take pictures of things they find under your sofa. They have microphones and voice recognition, and are able to ask how your day was when you get home from work. You can even activate their speakers and talk to your pets from the office. Unfortunately, so can anyone else if you don't install critical firmware updates.
JPCERT's warning says that the attacker must be on the same LAN to impersonate you, though "as a result, there is a possibility that an arbitrary operation may be conducted."

MojoKid writes: AMD Ryzen Mobile processors are arriving now in retail laptops from the likes of HP, Lenovo and Acer. With the first CPUs to hit the market, AMD took quad-core Ryzen and coupled it with 8 or 10-core Vega GPUs on a single piece of silicon in an effort to deliver a combination of strong Ryzen CPU performance along with significantly better integrated graphics performance over Intel's current 8th Gen Kaby Lake laptop chips. AMD Ryzen 7 2700U and Ryzen 5 2500U chips have 4MB of shared L3 cache each, but differ with respect to top-end CPU boost clock speeds, number of integrated Radeon Vega Compute Units (CUs), and the GPU's top-end clocks. Ryzen 7 2700U is more powerful with 10 Radeon Vega CUs, while Ryzen 5 2500U sports 8. Ryzen 7 2700U also boosts to 3.8GHz, while Ryzen 5 2500U tops out at 3.6GHz. In the benchmarks, Ryzen Mobile looks strong, competing well with Intel quad-core 8th Gen laptop CPUs, while offering north of 60 percent better performance in graphics and gaming. Battery life is still a question mark, however, as some of the very first models to hit the market from HP have inefficient displays and hard drives instead of SSDs. As more premium configurations hit the market in the next few weeks, hopefully we'll get a better picture of Ryzen Mobile battery life in more optimized laptop builds.

Rei writes: Tesla announced the completion of the world's largest battery -- a 100 MW/129 MWh wind-power backup system for 30,000 homes in South Australia. Three times more powerful than any other battery on Earth, the $50 million project had garnered press due to Elon Musk's Twitter boast that it would be completed within 100 days of the contract signing or it would be free. In the end, Tesla took it up a notch: the battery was finished 55 days from the date of contract signing and 99 days from the date of Musk's boast itself.

There is nothing that people want robots to be able to do more than to wash the dishes, according to Alphabet Chairman and former CEO Eric Schmidt. From a report: "When you ask a person what they would like a robot to do, the thing that they would like more than anyone else, is clean up the dishes in the kitchen," the billionaire Google executive says speaking at the Halifax International Security Forum. "That is literally the number one request. And I say this having done this exhaustively," he says. Though you may dream of a robot dishwasher, don't hold your breath for it to happen in the immediate future. "That turns out to be an extraordinarily difficult problem," says Schmidt.
