The New York Police Department said this week that it will stop using the "Digidog," a four-legged robot occasionally deployed for recon in dangerous situations. NYPD officials confirmed in a statement it had terminated its contract and will return the dog to vendor Boston Dynamics. Last December, the agency leased the Digidog, nicknamed Spot, for $94,000. From a report: John Miller, the police department's deputy commissioner for intelligence and counterterrorism, told The New York Times that the contract was "a casualty of politics, bad information, and cheap sound bites." Miller bemoaned the role of bad press in the backlash, but in many ways the NYPD's own actions were a blueprint for how not to introduce new tech. And, for activists, how to effectively agitate for banning unwanted technologies.

In truth, it wasn't just sound bites that doomed Spot. New Yorkers didn't want it. In February, the NYPD used Spot to defuse a hostage situation in the Bronx. When video of the device went viral, its flexible legs and camera-for-a-head design spooked people. The robot is quadrupedal but doesn't actually look like a dog. A more immediate comparison is the armed robots featured in a postapocalyptic episode of Black Mirror. This comparison spread rapidly on social media. The NYPD's secrecy worked against it: There was no public comment process for Spot, and residents hadn't known to expect to see robot-dogs respond to hostage situations. The NYPD had exactly this opportunity, months earlier, when it had to disclose both the price and governing policies for all surveillance devices as defined by the city's Public Oversight of Surveillance Technology (POST) Act. Instead, the agency included a passing reference to Spot in a larger section on "situational awareness cameras," with no images.

An anonymous reader quotes a report from PC Gamer: The Oculus Quest 2 is a hell of a lot of hardware for $299. In fact, we're convinced that Facebook is making a loss on each unit sold. Even so, that pricing is one of the main reasons it's the most popular headset on Steam and our pick as the best VR headset. Well, that and the ease of use. [...] The thing is, that price seems too good to be true, with no other manufacturer's VR headset close to the specs list of the Quest 2 -- in either tethered or standalone form -- hitting the same low, low price. That money gets you a robust virtual reality headset with 6GB of RAM, a Qualcomm Snapdragon XR2 CPU, 64GB of storage, 1832x1920 per eye display and a pair of controllers. [...]

But there's one factor that could potentially offset that price -- Facebook has access to a whole lot of your data. This is something the Oculus Quest 2 is upfront about: You absolutely need a Facebook account in order to use the device and it does have its data collection policies in black and white. Although what isn't quite so obvious is how much your data is worth to Facebook. At least it isn't without a tiny bit of digging.

There is another version of the Quest 2 that isn't as discounted as the consumer version, and that's the one aimed at businesses. The actual hardware is identical, but the difference is you don't need to login in with a Facebook account in order to use it. The price for this model? $799. There's also an annual fee of $180 that kicks in a year after purchase, which covers Oculus' business services and support, but that just muddies the waters a little. The point being, the Quest 2 for business, the headset from which Facebook can't access your data directly, costs $500 more. So that's looking essentially like the value the social media giant attributes to your data, which either seems like a lot or barely anything at all, depending on your stance. The Supplemental Oculus Data Policy outlines what sort of data is actually being collected when you use the Quest 2. Such things as your physical dimension, including your hand size, how big your play area is using the Oculus Guardian system, data on any content you create using the Quest 2, as well as more obvious stuff like your device ID and IP address.

An anonymous reader quotes a report from Motherboard: The IRS is looking for help to break into cryptocurrency hardware wallets, according to a document posted on the agency website in March of this year. Many cryptocurrency investors store their cryptographic keys, which confer ownership of their funds, with the exchange they use to transact or on a personal device. Some folks, however, want a little more security and use hardware wallets -- small physical drives which store a user's keys securely, unconnected to the internet. The law enforcement arm of the tax agency, IRS Criminal Investigation, and more specifically its Digital Forensic Unit, is now asking contractors to come up with solutions to hack into cryptowallets that could be of interest in investigations, the document states.

"The decentralization and anonymity provided by cryptocurrencies has fostered an environment for the storage and exchange of something of value, outside of the traditional purview of law enforcement and regulatory organizations," the document reads. "There is a portion of this cryptographic puzzle that continues to elude organizations -- millions, perhaps even billions of dollars, exist within cryptowallets." The security of hardware wallets presents a problem for investigators. The document states that agencies may be in possession of a hardware wallet as part of a case, but may not be able to access it if the suspect does not comply. This means that authorities cannot effectively "investigate the movement of currencies" and it may "prevent the forfeiture and recovery" of the funds. "The explicit outcome of this contract is to tame the cybersecurity research into measured, repeatable, consistent digital forensics processes that can be trained and followed in a digital forensics' laboratory," the document says.

Tesla CEO Elon Musk wants to turn every home into a distributed power plant that would generate, store and even deliver energy back into the electricity grid, all using the company's products. TechCrunch reports: While the company has been selling solar and energy storage products for years, a new company policy to only sell solar coupled with the energy storage products, along with Musk's comments Monday, reveal a strategy that aims to scale these businesses by appealing to utilities. "This is a prosperous future both for Tesla and for the utilities," he said. "If this is not done, the utilities will fail to serve their customers. They won't be able to do it," Musk said during an investor call, noting the rolling blackouts in California last summer and the more recent grid failure in Texas as evidence that grid reliability has become a bigger concern.

Last week, the company changed its website to prevent customers from only buying solar or its Powerwall energy storage product and instead required purchasing a system. Musk later announced the move in a tweet, stating "solar power will feed exclusively to Powerwall" and that "Powerwall will interface only between utility meter and house main breaker panel, enabling super simple install and seamless whole house backup during utility dropouts." Musk's pitch is that the grid would need more power lines, more power plants and larger substations to fully decarbonize using renewables plus storage. Distributed residential systems -- of course using Tesla products -- would provide a better path, in Musk's view. His claim has been backed up in part by recent studies from the Massachusetts Institute of Technology, which found that the U.S. can reach a zero-carbon grid by more than doubling its transmission capacity, and another from Princeton University showing that the country may need to triple its transmission systems by 2050 to reach net-zero emissions.

The next generation of Mac processors designed by Apple entered mass production this month, Nikkei Asia reported Tuesday, citing sources, bringing the U.S. tech giant one step closer to its goal of replacing Intel-designed central processing units with its own. From the report: Shipments of the new chipset -- tentatively known as the M2, after Apple's current M1 processor -- could begin as early as July for use in MacBooks that are scheduled to go on sale in the second half of this year, the people said. The new chipset is produced by key Apple supplier Taiwan Semiconductor Manufacturing Co., the world's largest contract chipmaker, using the latest semiconductor production technology, known as 5-nanometer plus, or N5P. Producing such advanced chipsets takes at least three months. The start of mass production came as Apple introduced new iMac and iPad Pro models using the M1. The company said the M1 offers CPU performance up to 85% faster than an iMac using an Intel chipset, and graphics performance that is twice as fast.

For TSMC, being the world's largest foundry with nearly 500 customers has its peculiarities. On the one hand, the company can serve almost any client with almost any requirements. On the other hand, it has to stay ahead of everyone else both in terms of capacity and in terms of technology. As far as capacity is concerned, TSMC is unchallenged and is not going to be for years to come. From a report: As for fabrication technologies, TSMC has recently reiterated that it's confident that its N2, N3, and N4 processes will be available on time and will be more advanced than competing nodes. Early this year TSMC significantly boosted its 2021 CapEx budget to a $25-$28 billion range, further increasing it to around $30 billion as a part of its three-year plan to spend $100 billion on manufacturing capacities and R&D. [...] TSMC's N5 family of technologies also includes evolutionary N4 process that will enter risk production later this year and will be used for mass production in 2022. [...] In 2022, the world's largest contract maker of chips will roll out its brand-new N3 manufacturing process, which will keep using FinFET transistors, but is expected to offer the whole package of PPA improvements.

Jack Dorsey, the co-founder and CEO of Twitter, tweeted Wednesday that bitcoin "incentivises renewable energy." And Elon Musk responded "True."

The BBC adds that the tweets came "despite experts warning otherwise." The cyrptocurrency's carbon footprint is as large as some of the world's biggest cities, studies suggest. But Mr Dorsey claims that could change if bitcoin miners worked hand-in-hand with renewable energy firms.

One expert said it was a "cynical attempt to greenwash" bitcoin. China, where more than two-thirds of power is from coal, accounts for more than 75% of bitcoin mining around the world...

The tweet comes soon after the release of a White Paper from Mr Dorsey's digital payment services firm Square, and global asset management business ARK Invest. Entitled "Bitcoin as key to an abundant, clean energy future", the paper argues that "bitcoin miners are unique energy buyers", because they offer flexibility, pay in a cryptocurrency, and can be based anywhere with an internet connection. "By combining miners with renewables and storage projects, we believe it could improve the returns for project investors and developers, moving more solar and wind projects into profitable territory," it said.

Author and bitcoin critic David Gerard described the paper as a "cynical exercise in bitcoin greenwashing".

"The reality is: bitcoin runs on coal," he told the BBC.... "Bitcoin mining is so ghastly and egregious that the number one job of bitcoin promoters is to make excuses for it — any excuse at all."

An anonymous reader quotes a report from South China Morning Post: In a rare public appearance since retiring nearly three years ago, Morris Chang, the 89-year-old founder of the world's largest contract chip maker, said China is not yet a competitor in chipmaking and that Taiwan should defend its leadership in semiconductor manufacturing. "Mainland China has given out subsidies to the tune of tens of billions of US dollars over the past 20 years but it is still five years behind TSMC," Chang said. "Its logic chip design capability is still one to two years behind the US and Taiwan. The mainland is still not yet a competitor."

In his speech, Chang also took a swipe at US chip giant Intel, describing its recent decision to enter the contract chip making market as "very ironic" because it turned down an opportunity to invest in TSMC more than three decades ago. Contract chip makers like TSMC typically take orders from so-called fabless chip makers like Qualcomm, which design their products but outsource the manufacturing. Chang said he was rejected by Intel when he approached it for funding in 1985. "In the past, Intel was the alpha sneering at us and thought that we would never get big," he said. "They never thought the business of [outsourced] wafer fabrication would become so important today."

Chang said the US is also at a disadvantage compared with Taiwan because it lacks engineers dedicated to the semiconductor manufacturing sector, adding that the "US level of dedication to manufacturing was absolutely no match for that of Taiwan." "What I need right now are capable and dedicated engineers, technicians and operators. And they have to be willing to throw themselves into manufacturing," he said. "In the US, doing manufacturing isn't popular. It hasn't been popular for decades."

According to Sacramento CBS affiliate KOVR-TV, Yana Sydnor called the police to report a possible home invasion. Turns out, it was a robovac that her son turned on before leaving for the weekend. Android Police reports: At 1 a.m., she and her 2-year-old daughter woke up to loud booms coming from her stairs disrupting her meditation music. She texted her friends about the sounds before they quickly responded, urging her to call 911. "I hear someone walking down my stairs, so it's like boom, boom, boom, boom, boom," Sydnor recalls telling the dispatcher. Desperate to exit the house and avoid a run-in with the invader, she ran to the bathroom, put her daughter in the tub, and thought about grabbing a ladder to get them both outside to ground level.

Officers arrived within 10 minutes of Sydnor's call. They rammed the front door wide open only to find a poor robovac, fresh from a tumble down a flight of stairs. "My son turned on the vacuum cleaner because he didn't want to do chores before he left for the weekend," she explained to the reporter after a moment of exasperated silence. The vacuum hadn't been used for 2 years and, even after the fall, it still works. We couldn't make out the make and model of the robovac, so we don't quite know if it could stop itself from going over the ledge much less what exactly happened in this case if it did have the ability.

chicksdaddy shares a report from The Security Ledger: Websites for customers of agricultural equipment maker John Deere contained vulnerabilities that could have allowed a remote attacker to harvest sensitive information on the company's customers including their names, physical addresses and information on the Deere equipment they own and operate, The Security Ledger reported. The researcher known as "Sick Codes" published two advisories on Thursday warning about the flaws in the myjohndeere.com website and the John Deere Operations Center website and mobile applications. In a conversation with Security Ledger, the researcher said that a he was able to use VINs (vehicle identification numbers) taken from a farm equipment auction site to identify the name and physical address of the owner. Furthermore, a flaw in the myjohndeere.com website could allow an unauthenticated user to carry out automated attacks against the site, possibly revealing all the user accounts for that site.

Sick Codes disclosed both flaws to John Deere and also to the U.S. Government's Cybersecurity and Infrastructure Security Agency (CISA), which monitors food and agriculture as a critical infrastructure sector. The information obtained from the John Deere websites, including customer names and addresses, could put the company afoul of data security laws like California's CCPA or the Personal Information Protection Act in Deere's home state of Illinois. However, the national security consequences of the company's leaky website could be far greater. Details on what model combines and other equipment is in use on what farm could be of very high value to an attacker, including nation-states interested in disrupting U.S. agricultural production at key junctures, such as during planting or harvest time.

The consolidated nature of U.S. farming means that an attacker with knowledge of specific, Internet connected machinery in use by a small number of large-scale farming operations in the midwestern United States could launch targeted attacks on that equipment that could disrupt the entire U.S. food supply chain, researchers warn. The Agriculture sector and firms that supply it, like Deere, lag other industries in cyber security preparedness and resilience. A 2019 report (PDF) released by Department of Homeland Security concluded that the "adoption of advanced precision agriculture technology and farm information management systems in the crop and livestock sectors is introducing new vulnerabilities" (and that) "potential threats to precision agriculture were often not fully understood or were not being treated seriously enough by the front-line agriculture producers."

According to a report from the U.S. Energy Information Administration (EIA), Texas will add a record 10 GW of utility-scale solar capacity by the end of 2022, compared with 3.2 GW in California. A third of all U.S. utility-scale solar capacity planned to come online in the next two years (30 GW) will be in Texas. Reuters reports: California currently has the most installed utility-scale solar capacity of any state - about 16 gigawatts (GW). One gigawatt can power about 1 million U.S. homes. But since solar power is on only about a third of the time, a gigawatt of solar can only power about 330,000 homes. Texas added 2.5 GW of solar capacity in 2020, and EIA said it expected the state to add another 4.6 GW in 2021 and 5.4 GW in 2022, bringing the state's total to 14.9 GW. Solar is expected to make up the largest share of capacity additions in Texas between 2020 and 2022, with almost half of the additions, compared with 35% for wind and 13% for gas, according to EIA projections.

At today's Spring Loaded event, Apple unveiled a new version of the iPad Pro, equipped with the M1 chip that was first introduced on the company's Mac line. TechCrunch reports: The new chip sports an 8-core CPU, with performance up to 50% faster than the A12Z Bionic found on the previous generation. There's also an 8-core GPU, which it claims is up to 40% faster. The system can be decked out to up to 16 GB of RAM and 2 TB of storage. The device further blurs the line between the company's tablet and desktop offerings, as well as improved battery life now listed as "all day." The Pro also adds Thunderbolt support to the USB-C, which allows for a number of new features including external display support and wired transfers up to 40 Gbps.

As reported, the new tablet (12.9-inch only for now) features an improved display -- Liquid Retina XDR, according to Apple's marketing terms. Among other things that brings much improved high dynamic range. The display is powered by 10,000 micro-LED. That allows for a hugely improved contrast ratio and 1,000 nits of brightness, without hammering the battery life. The 11-inch version starts at $799 and the 12.9-inch, which adds the Liquid Retina display, starts at $1,099. Pre-orders on the tablets starts April 30 and the product is set to start shipping in the second half of May -- along with a number of other products introduced at today's show.

Researchers have developed a tool that can design complex DNA robots and nanodevices in minutes instead of days. Phys.Org reports: In a paper published today in the journal Nature Materials, researchers from The Ohio State University -- led by former engineering doctoral student Chao-Min Huang -- unveiled new software they call MagicDNA. The software helps researchers design ways to take tiny strands of DNA and combine them into complex structures with parts like rotors and hinges that can move and complete a variety of tasks, including drug delivery. One advantage is that it allows researchers to carry out the entire design truly in 3-D. Earlier design tools only allowed creation in 2-D, forcing researchers to map their creations into 3-D. That meant designers couldn't make their devices too complex.

The software also allows designers to build DNA structures "bottom up" or "top down." In "bottom up" design, researchers take individual strands of DNA and decide how to organize them into the structure they want, which allows fine control over local device structure and properties. But they can also take a "top down" approach where they decide how their overall device needs to be shaped geometrically and then automate how the DNA strands are put together. Combining the two allows for increasing complexity of the overall geometry while maintaining precise control over individual component properties. Another key element of the software is that it allows simulations of how designed DNA devices would move and operate in the real world.

An anonymous reader quotes a report from 9to5Google: The latest addition coming to Microsoft Edge is "performance mode." Rolling out first to the Canary channel, "performance mode" in Microsoft Edge is designed to improve how the browser uses the resources available to it. In practice, Microsoft says the new mode will improve speed and responsiveness overall while "optimizing" the use of battery, CPU, and RAM. Apparently, the mode may adjust based on your browsing habits too. "Performance mode helps you optimize speed, responsiveness, memory, CPU and battery usage," says Microsoft. "Performance improvements might vary depending on your individual specifications and browser habits."

One specific change Microsoft notes is that the "Sleeping Tabs" feature in Edge will be locked to five minutes when performance mode is turned on. "Sleeping Tabs" essentially freezes a tab that's left open in the background, saving resources when it's not actively being used. Performance Mode is rolling out now in version 91.0.856.0, available in the Canary channel. The toggle is available in the "System" section of the settings menu.

schwit1 writes: Able to move 1,600 boxes per hour using just one arm, Dill relies on humans to keep it operating efficiently Pickle Robots says that Dill's approach to the box unloading task is unique in a couple of ways. First, it can handle messy trailers filled with a jumble of boxes of different shapes, colors, sizes, and weights. And second, from the get-go it's intended to work under human supervision, relying on people to step in and handle edge cases.

We asked Meyer how much Dill costs, and to our surprise, he gave us a candid answer: Depending on the configuration, the system can cost anywhere from $50-100k to deploy and about that same amount per year to operate. Meyer points out that you can't really compare the robot to a human (or humans) simply on speed, since with the robot, you don't have to worry about injuries or improper sorting of packages or training or turnover. While Pickle is currently working on several other configurations of robots for package handling, this particular truck unloading configuration will be shipping to customers next year.

"Jensen Huang, the CEO of Nvidia, the nation's most valuable semiconductor company, with a stock price of $645 a share and a market cap of $400 billion, is out to create the metaverse," writes Time magazine.

Huang defines it as "a virtual world that is a digital twin of ours." Huang credits author Neal Stephenson's Snow Crash, filled with collectives of shared 3-D spaces and virtually enhanced physical spaces that are extensions of the Internet, for conjuring the metaverse. This is already playing out with the massively popular online games like Fortnite and Minecraft, where users create richly imagined virtual worlds. Now the concept is being put to work by Nvidia and others.

Partnering with Nvidia, BMW is using a virtual digital twin of a factory in Regensburg, Germany, to virtually plan new workflows before deploying the changes in real time in their physical factory. The metaverse, says Huang, "is where we will create the future" and transform how the world's biggest industries operate...

Not to make any value judgments about the importance of video games, but do you find it ironic that a company that has its roots in entertainment is now providing vitally important computing power for drug discovery, basic research and reinventing manufacturing?

No, not at all. It's actually the opposite. We always started as a computing company. It just turned out that our first killer app was video games...

How important is the advent and the adaptation of digital twins for manufacturing, business and society at large?

In the future, the digital world or the virtual world will be thousands of times bigger than the physical world. There will be a new New York City. There'll be a new Shanghai. Every single factory and every single building will have a digital twin that will simulate and track the physical version of it. Always. By doing so, engineers and software programmers could simulate new software that will ultimately run in the physical version of the car, the physical version of the robot, the physical version of the airport, the physical version of the building. All of the software that's going to be running in these physical things will be simulated in the digital twin first, and then it will be downloaded into the physical version. And as a result, the product keeps getting better at an exponential rate.

The second thing is, you're going to be able to go in and out of the two worlds through wormholes. We'll go into the virtual world using virtual reality, and the objects in the virtual world, in the digital world, will come into the physical world, using augmented reality. So what's going to happen is pieces of the digital world will be temporarily, or even semipermanently, augmenting our physical world. It's ultimately about the fusion of the virtual world and the physical world.

The New York Focus site writes: A decade ago, the bankrupt owner of the Greenidge power plant in Dresden, New York, sold the uncompetitive coal-fired relic for scrap and surrendered its operating permits. For the next seven years, the plant sat idle on the western shore of Seneca Lake, a monument to the apparent dead end reached by the state's fossil fuel infrastructure. But today, Greenidge is back up and running as a Bitcoin mining operation. The facility hums with energy-hungry computers that confirm and record Bitcoin transactions, drawing power from the plant's 106-megawatt generator now fueled by natural gas.

The mining activity is exceptionally profitable, thanks to an 800 percent rise in Bitcoin's price since last April. Seeking to ride the boom, the plant's new owners plan to quadruple the power used to process Bitcoin transactions by late next year. Environmental advocates view Greenidge's ambitions, if left unchecked, as an air emissions nightmare. And they fear that dozens of other retired or retiring fossil-fueled power plants across New York could follow Greenidge's example, gaining new life by repurposing as Bitcoin miners or other types of energy-intense data centers.
The New York Times recently touted an alternative to bitcoin mining: the "proof of stake" method, which "instead awards miners new blocks based on how much cryptocurrency they already own." The world's second-largest cryptocurrency by market capitalization, Ethereum, has said it is moving toward proof of stake (that switch is likely to take up to another year). Though some critics say Bitcoin will eventually need to follow, particularly if an environmental backlash grows, there are no current plans to do so and such a move is unpopular within the Bitcoin community.

"That reduces your emissions to almost nothing," said Joseph Pallant, Blockchain for Climate's founder and executive director. Cryptocurrency platforms like Tezos or Near Protocol already use proof of stake and have vastly lowered their energy use.

An anonymous reader quotes a report from IGN: In its first five months on the market, The PlayStation 5 has become the fastest-selling console in U.S. history in both unit and dollar sales. As revealed by The NPD Group's Mat Piscatella, this news arrives one month after the PS5 became the fastest-selling console in U.S. history in dollar sales. Despite that new record, the Nintendo Switch has continued its reign as the best selling hardware platform in both units and dollars during March 2021. However, the PS5 did rank first in hardware dollar sales in Q1 2021.

In his final letter to shareholders as Amazon CEO, Jeff Bezos said that the company has to "do a better job for our employees." But, as The Verge points out, the outlined strategy includes "a robotic scheme that will develop new staffing schedules using an algorithm." From the report: Bezos pushed back on the idea that, according to news reports, Amazon doesn't care for its employees. "In those reports, our employees are sometimes accused of being desperate souls and treated as robots. That's not accurate,â he wrote. To address concerns about working conditions, Bezos said the company will develop new staffing schedules "that use sophisticated algorithms to rotate employees among jobs that use different muscle-tendon groups to decrease repetitive motion and help protect employees from MSD risks." The technology will roll out throughout 2021, he said.

In addition to giving a nod to working conditions at Amazon, the letter is the first time Bezos has publicly addressed the failed union drive at its Bessemer, Alabama plant. "Does your Chair take comfort in the outcome of the recent union vote in Bessemer? No, he doesn't," Bezos wrote. "I think we need to do a better job for our employees. While the voting results were lopsided and our direct relationship with employees is strong, it's clear to me that we need a better vision for how we create value for employees -- a vision for their success."

How many years will the ongoing chip shortage affect technology firms across the world? This week, multiple tech executives offered their own dismal estimates as part of their usual public financial disclosures, with the worst one coming in at "a couple of years." From a report: That nasty estimate comes from Intel CEO Pat Gelsinger, who offered that vague timeframe to The Washington Post in an interview on Tuesday. He clarified that was an estimate for how long it would take the company to "build capacity" to potentially address supply shortages. The conversation came as Intel offered to step up for two supply chains particularly pinched by the silicon drought: medical supplies and in-car computer systems.

In previous statements, Gelsinger pointed to Intel's current $20 billion plan to build a pair of factories in Arizona, and this week's interview added praise for President Joe Biden's proposed $50 billion chip-production infrastructure plan -- though Gelsinger indicated that Biden should be ready to spend more than that. TSMC CEO C.C. Wei offered a similarly dire estimate to investors on Thursday, saying that the Taiwan-based company hoped to "offer more capacity" for meeting retail and manufacturing demand "in 2023." TSMC, coincidentally, is moving forward with a manufacturing plant of its own in Arizona, which Bloomberg claims could cost "up to $12 billion," despite the company clarifying that it intends to prioritize research, development, and production in its home nation.
