MojoKid writes: In recent months, the cryptocurrency industry has taken a sharp downturn in valuations of virtually all major currencies, from Bitcoin to Ethereum. As a result, cryptocurrency mining itself has become significantly less lucrative for the average miner. In addition, demand on GPUs from the major OEM suppliers like NVIDIA and AMD, has fallen off dramatically as well. Cryptocurrency miner demand for graphics cards has fallen so much so, that pricing of board partner brands like EVGA, Asus, MSI, Gigabyte and others, has returned basically to MSRP levels. This is compared to the sharp price gouging that was going on earlier in 2018 and late last year, when demand was far out-stripping supply. In fact, reports are emerging now that another approximate 20 percent price drop could be coming to GPUs this month, especially as NVIDIA is expected to launch its next generation gaming graphics card very soon. Whether or not this is indicative of some sort of cryptocurrency bubble burst remains to be seen. However, for now, gamers and PC enthusiasts are likely breathing a sigh of relief, as better supply/demand dynamics are clearly in sight.

An anonymous reader shares a report: Homeland Security has served Twitter with a subpoena, demanding the account information of a data breach finder, credited with finding several large caches of exposed and leaking data. The New Zealand national, whose name isn't known but goes by the handle Flash Gordon, revealed the subpoena in a tweet last month. The pseudonymous data breach finder regularly tweets about leaked data, found on exposed and unprotected servers. Last year, he found a trove of almost a million patients' data leaking from a medical telemarketing firm. A recent find included an exposed cache of law enforcement data by ALERRT, a Texas State University-based organization, which trains police and civilians against active shooters. The database, secured in March but reported last week, revealed that several police departments were under-resourced and unable to respond to active shooter situations.

Homeland Security's export control agency, Immigration and Customs Enforcement (ICE), served the subpoena to Twitter on April 24, demanding information about the data breach finder's account. ICE demanded Twitter turn over his screen name, address, phone number -- and any other identifying information about the account, including credit cards on the account. The subpoena also demanded the account's IP address history, member lists, and any complaints filed against the Twitter account.

An anonymous reader quotes the Independent: Millions of people face the prospect of being scanned by police facial recognition technology that has sparked human rights concerns. The controversial software, which officers use to identify suspects, has been found to be "staggeringly inaccurate", while campaigners have branded its use a violation of privacy. But Britain's largest police force is set to expand a trial across six locations in London over the coming months.

Police leaders claimed officers make the decision to act on potential matches with police records and images that do not spark an alert are immediately deleted. But last month The Independent revealed the Metropolitan Police's software was returning "false positives" -- images of people who were not on a police database -- in 98 percent of alerts... Detective Superintendent Bernie Galopin, the lead on facial recognition for London's Metropolitan Police, said the operation was targeting wanted suspects to help reduce violent crime and make the area safer. "It allows us to deal with persons that are wanted by police where traditional methods may have failed," he told The Independent, after statistics showed police were failing to solve 63 per cent of knife crimes committed against under-25s....

Det Supt Galopin said the Met was assessing how effective facial recognition was at tackling different challenges in British policing, which is currently being stretched by budget cuts, falling officer numbers, rising demand and the terror threat.
A policy officer from the National Council for Civil Liberties called the technology "lawless," adding "the use of this technology in a public place is not compatible with privacy, and has a chilling effect on society."

But a Home Office minister said the technology was vital for protecting people from terrorism, though "we must ensure that privacy is respected. This strategy makes clear that we will grasp the opportunities that technology brings while remaining committed to strengthening safeguards."

An anonymous reader quotes the New York Times: We've hit what I call Peak Screen. For much of the last decade, a technology industry ruled by smartphones has pursued a singular goal of completely conquering our eyes. It has given us phones with ever-bigger screens and phones with unbelievable cameras, not to mention virtual reality goggles and several attempts at camera-glasses. Tech has now captured pretty much all visual capacity. Americans spend three to four hours a day looking at their phones and about 11 hours a day looking at screens of any kind.

So tech giants are building the beginning of something new: a less insistently visual tech world, a digital landscape that relies on voice assistants, headphones, watches and other wearables to take some pressure off our eyes. This could be a nightmare; we may simply add these new devices to our screen-addled lives. But depending on how these technologies develop, a digital ecosystem that demands less of our eyes could be better for everyone -- less immersive, less addictive, more conducive to multitasking, less socially awkward, and perhaps even a salve for our politics and social relations. Who will bring us this future? Amazon and Google are clearly big players, but don't discount the company that got us to Peak Screen in the first place. With advances to the Apple Watch and AirPods headphones, Apple is slowly and almost quietly creating an alternative to its phones... If it works, it could change everything again.
Warning that screens are insatiable vampires for your attention, the piece argues we should be using our phones more mindfully -- and exploring "less immersive ways to interact with the digital world" like Google and Amazon voice assisants.

"The sooner we find something else, the better."

An anonymous reader quotes Reuters: Bitcoin's value slid to its lowest level since November on Friday, as waning investor interest and recent negative headlines from global regulators weakened demand for the cryptocurrency and most of its rivals. Virtual currencies, including the best-known and biggest, bitcoin, have been stuck in a downward trend for most of 2018 after last year's frenzied interest fizzled. Recent hacks and the "cyber intrusion" of cryptocurrency exchanges in key Asian markets has also encouraged investors to exit.

Bitcoin fell to as low as $5,774 on the Bitstamp exchange, the lowest since November 12... So far in 2018, bitcoin has tumbled almost 60 percent after soaring more than 1,300 percent last year. It is now down 70 percent from its December peak... The total market capitalization of cryptocurrencies has fallen to around $230 billion from a peak of around $800 billion in January.
Will Hobbs, Head of Investment Strategy at Barclays Smart Investor, now tells Reuters that "None of the crypto currencies currently fulfill any of the criteria that we would look for in an investible asset, and we would continue to advise extreme caution. The rout in crypto currencies is still not finished."

Bloomberg Businessweek Middle East reports: India's space program wants to go where no nation has gone before -- to the south side of the moon. And once it gets there, it will study the potential for mining a source of waste-free nuclear energy that could be worth trillions of dollars. The nation's equivalent of NASA will launch a rover in October to explore virgin territory on the lunar surface and analyze crust samples for signs of water and helium-3. That isotope is limited on Earth yet so abundant on the moon that it theoretically could meet global energy demands for 250 years if harnessed....

[A]ccomplishing feats on the cheap has been a hallmark of the agency since the 1960s. The upcoming mission will cost about $125 million -- or less than a quarter of Snap Inc. co-founder Evan Spiegel's compensation last year, the highest for an executive of a publicly traded company, according to the Bloomberg Pay Index... The upcoming launch of Chandrayaan-2 includes an orbiter, lander and a rectangular rover. The six-wheeled vehicle, powered by solar energy, will collect information for at least 14 days and cover an area with a 400-meter radius. The rover will send images to the lander, and the lander will transmit those back to ISRO for analysis. A primary objective, though, is to search for deposits of helium-3. Solar winds have bombarded the moon with immense quantities of helium-3 because it's not protected by a magnetic field like Earth is.
The European Space Agency points out that helium-3 isotope isn't radioactive and "would not produce dangerous waste products." And one former member of the NASA Advisory Council estimates that the moon-derived fuel could generate enough power to meet the world's energy demands for between two at least two centuries.

An anonymous reader quotes a report from Ars Technica: A new study led by the University of California, Santa Cruz's Greg Rau highlights another tool for our CO2 removal toolbox: splitting seawater to produce hydrogen gas for fuel while capturing CO2 with ocean chemistry. In electrolysis, a device powered by electricity is used to split H2O, producing hydrogen gas. Several chemical modifications to this process have been proposed that can also grab CO2 from the atmosphere. Like the idea of using biofuels, this represents a "win-win" by producing an energy resource while capturing CO2, bringing the cost down. [T]he gist is that atmospheric CO2 goes into the ocean as bicarbonate -- which won't acidify the water or harm ecosystems. So if you power the electrolysis process with renewable energy, you can turn solar/wind/hydroelectric energy into hydrogen fuel while also removing CO2 from the air.

The new study focuses on a basic estimate of the cost and maximum potential of this technique. First, the researchers worked out its efficiency of CO2 capture -- about 0.3 tons captured per gigajoule of electricity input, including the losses from quarrying and crushing rock. That's around 10 times greater than biofuel schemes, but it depends on the assumption that there is demand for all the hydrogen fuel you make. The hydrogen can be used by vehicles, and there's the possibility of using hydrogen as a type of storage for the electric grid -- using excess power to make hydrogen that can run a power plant when needed. So it's not too farfetched that demand could rise to meet supply. The researchers' back-of-the-envelope estimate puts the cost of this system at between $3 and $161 per ton of captured CO2, depending on which type of renewable energy powers it. The study has been published in the journal Nature Climate Change.

An anonymous reader shares a report: Intel's delayed release of a new processor is going to have a noticeable effect on the laptop market this year. As there is little chance of seeing anything new until towards the end of this year, laptop designers will not be able to offer new models for the holidays and will instead have to rework existing products. DigiTimes suggests we will see trimmed down models with lower price tags to try to entice consumers into purchasing something, as they expect lower demand than we saw last year. Hopefully some gaming machines may become more affordable, or we will start to see models incorporating AMD's new chips become more common.

An anonymous reader quotes a report from NPR: The city of Orlando, Fla., says it has ended a pilot program in which its police force used Amazon's real-time facial recognition -- a system called "Rekognition" that had triggered complaints from rights and privacy groups when its use was revealed earlier this year. Orlando's deal to open part of its camera systems to Amazon was reported by NPR's Martin Kaste in May, after the ACLU noticed that an Amazon Rekognition executive mentioned the city as a customer.

On Monday, the ACLU of Florida wrote a letter to Mayor Buddy Dyer and the Orlando City Council, demanding that the city "immediately" shut down "any face surveillance deployment or use by city agencies and departments." On the same day, Orlando city and police officials issued a joint statement saying that the test of how its officers might use the Rekognition technology ended last week. The city added, "Staff continues to discuss and evaluate whether to recommend continuation of the pilot at a further date," adding that "the contract with Amazon remains expired." Orlando police say the test was limited to only a fraction of the city's cameras, and that the system was tested by tracking its own officers. The Rekognition deal with Orlando caused a stir after Ranju Das, the head of the Rekognition unit, said in early May: "City of Orlando is a launch partner of ours. It's a smart city; they have cameras all over the city. The authorized cameras are then streaming the data [...] we are a subscriber to the stream, we analyze the video in real time, search against the collection of faces that they have."

An anonymous reader shares a report: A U.S. judge who held a hearing about climate change that received widespread attention ruled Monday that Congress and the president were best suited to address the contribution of fossil fuels to global warming. So he threw out lawsuits that sought to hold big oil companies liable for the Earth's changing environment. Noting that the world has also benefited significantly from oil and other fossil fuel, Judge William Alsup said questions about how to balance the "worldwide positives of the energy" against its role in global warming "demand the expertise of our environmental agencies, our diplomats, our Executive, and at least the Senate. The problem deserves a solution on a more vast scale than can be supplied by a district judge or jury in a public nuisance case," he said. Alsup's ruling came in lawsuits brought by San Francisco and neighboring Oakland that accused Chevron (CVX), Exxon Mobil (XOM), ConocoPhillips (COP), BP (BP) and Royal Dutch Shell (RDS.A) of long knowing that fossil fuels posed serious risks to the environment, but still promoting them as environmentally responsible.

Valve's "Knuckles" controllers for VR, first introduced in 2016, are getting upgraded. According to Engadget, Valve is "sending game makers another version, the EV2, that has revamped buttons, straps and a slew of sensors that essentially translate finger motion and pressure to let you touch, grab and squeeze objects inside games." From the report: Some of the EV2's changes are evident: The old Steam Controller-style touchpad that dominated the controller's top has been shrunken to an oval 'track button' that measures touch and force. That's flanked by traditional inputs: A joystick (by developer demand, Valve noted in a blog post) and standard circular buttons. The strap is adjustable for different hand sizes and pulls tight to let players let go of the controller completely without dropping it -- which could be key for the pressure inputs.

While last year's model had touch inputs tracking each finger in the 'grip' area, the EV2 introduces pressure sensors that measure how much force the wielder is using. Obviously, this has implications for VR developers who want players to grip or squeeze objects in the world, but as Valve's blog post points out, combining those with the touch sensors tells games when players let go of the grips -- like, say, when they're throwing things in-game. Lastly, the battery life has been extended to last six hours.

Chinese raids of U.S. intellectual property have helped China build a solid high-tech economy. But the U.S. semiconductor industry is still far ahead -- and China is desperate to catch up. From a report: Semiconductor manufacturers are fighting to protect IP from the Chinese, fearing that, without coherent action from the Trump administration, Beijing could bulldoze their industries. Three weeks ago, Micron and South Korean chipmakers Samsung and SK Hynix all reported that the Chinese government had launched antitrust probes into their firms, and accused them of setting artificially high prices for memory chips. American companies and the U.S. government have long been suspicious about the link between China's anti-monopoly policies and its industrial goals. "They want access to the intellectual property. They need us to teach them how to do it. Once they have the industry, they want to push us out," an industry source familiar with China's investigation into Micron tells Axios. The price hikes, the source says, are largely due to a boom in demand for memory chips in everything from smartphones to autonomous vehicles. China's investigation is "a clear indication that they're not ready to make [semiconductors] work," says the source. The New York Times has a story which also details the lawsuit of how a Fujian govt-backed chipmaker allegedly stole secrets from Micron. Then Micron got sued for patent infringement in Fujian.

Or as the Times reporter describes it, "This is how you lose a major tech company. First, a Beijing-backed buyout offer. Then friendly Chinese partnership proposals. Then the tech gets stolen. Then when you file a complaint in court, you get hit with investigations in China, your biggest market."

An anonymous reader writes: Conamix, a little-known startup based in Ithaca, New York, has raised several million dollars to accelerate its development of cobalt-free materials for lithium-ion batteries, the latest sign that companies are eager to find alternatives to the increasingly rare and expensive metal. The problem: The price of cobalt has more than doubled in recent months, as global demand skyrockets for the lithium-ion batteries that power electric vehicles and smartphones. It's also being driven up by the fact that the metal is mined primarily in the Democratic Republic of Congo, where labor and corruption issues are rife. Earlier this year, the nation decided to raise royalties on cobalt and other metals.

Given the ambitious expansion plans of lithium-ion producers, the world will face cobalt shortages by the early 2020s, according to Bloomberg New Energy Finance. This is keeping prices of lithium-ion batteries high and preventing major automakers from lining up long-term supply deals on favorable terms. The mounting threat to electric-vehicle growth has prompted a growing number of companies to explore other solutions.

Reports out of Taiwan now suggest that Nvidia has a gaming GPU inventory problem. An anonymous reader writes: Tech news site SemiAccurate which covers the GPU space pretty closely, and has broken stories like AMD's acquisition of ATI Technologies and Nvidia's Bumpgate, just published an article on why Nvidia has delayed their new gaming GPUs. It seems the Hot Chips 30 agenda cancellation and Jensen's no new GPUs for 'a long time' comment have created enough of a stir to get journalists and industry insiders asking questions. While curiosity amongst all this confusion is natural, I was surprised to discover that people were starting to speculate Nvidia's delay was due to technical issues with their new GPUs. This had never been a concern of mine, and as it turns out, it's clearly not the case. So, what the problem? Nvidia has overestimated pent-up gaming demand and underestimated the impact of declining mining demand.

Yesterday, 43-year-old Iowa man Sherman Hopkins Jr. was sentenced to 20 years in prison for attempting to rob a domain name from another man at gunpoint in 2017. As Motherboard reports, "this may be the first time someone has attempted to steal a domain name at gunpoint." From the report: Last June, Hopkins broke into the home of 26 year-old Ethan Deyo in Cedar Rapids, Iowa one afternoon and demanded that Deyo to log on to his computer to transfer the domain name for "doitforstate.com" to another account. According to Deyo's bio on his personal website, he is a web entrepreneur who previously worked for the web hosting service GoDaddy. After seeing Hopkins enter the apartment, Deyo locked himself into his room and Hopkins kicked in the door. Hopkins kicked in the door and "pistol-whipped" Deyo, held a gun to his head and used a stun gun on him during the encounter. While he attempted to wrestle the gun away from Hopkins, Deyo was shot in the leg, but he eventually gained control of the firearm and shot Hopkins multiple times in the chest. It's unclear why Hopkins wanted the domain name or who he was transferring the domain name to.

A concentrated campaign of price manipulation may have accounted for at least half of the increase in the price of Bitcoin and other big cryptocurrencies last year, according to a paper released on Wednesday by an academic with a history of spotting fraud in financial markets. From a report, first shared to us by reader davidwr: The paper by John Griffin, a finance professor at the University of Texas, and Amin Shams, a graduate student, is likely to stoke a debate about how much of Bitcoin's skyrocketing gain last year was caused by the covert actions of a few big players, rather than real demand from investors. Many industry players expressed concern at the time that the prices were being pushed up at least partly by activity at Bitfinex, one of the largest and least regulated exchanges in the industry. The exchange, which is registered in the Caribbean with offices in Asia, was subpoenaed by American regulators shortly after articles about the concerns appeared in The New York Times and other publications. Mr. Griffin looked at the flow of digital tokens going in and out of Bitfinex and identified several distinct patterns that suggest that someone or some people at the exchange successfully worked to push up prices when they sagged at other exchanges. To do that, the person or people used a secondary virtual currency, known as Tether, which was created and sold by the owners of Bitfinex, to buy up those other cryptocurrencies.

An anonymous reader quotes InfoQ: Ron Jeffries, author, speaker, one of the creators of Extreme Programming (XP), and a signatory of the Agile Manifesto back in 2001, shared a post on his blog in which he advocates that developers should abandon "Agile". The post further elaborated that developers should stay away from the "Faux Agile" or "Dark Agile" forms, and instead get closer to the values and principles of the Manifesto. The terms "Faux Agile" and "Dark Agile" are used by the author to give emphasis to the variety of the so-called "Agile" approaches that have contributed, according to him, to make the life of the developers worse rather than better, which is the antithesis of one of the initial ideas of the Agile Manifesto...
Jeffries writes that "When 'Agile' ideas are applied poorly, they often lead to more interference with developers, less time to do the work, higher pressure, and demands to 'go faster'. This is bad for the developers, and, ultimately, bad for the enterprise as well, because doing 'Agile' poorly will result, more often than not, in far more defects and much slower progress than could be attained. Often, good developers leave such organizations, resulting in a less effective enterprise than prior to installing 'Agile'...

"it breaks my heart to see the ideas we wrote about in the Agile Manifesto used to make developers' lives worse, instead of better. It also saddens me that the enterprise isn't getting what it could out of the deal, but my main concern is for the people doing the work..." He argues developers should instead just focus on Agile's good general software development practices -- like regularly producing fully-tested software and consciously avoiding "crufty" complex designs.

But what do Slashdot's readers think? Should developers abandon Agile?

Since there aren't enough construction workers in the country to keep up with housing demands, the city of Eindhoven in The Netherlands is turning to robots for help. The city will soon boast the world's first commercially-developed 3D-printed homes, a endeavor known as Project Milestone. The project is being handled by Dutch construction company Van Wijnen and researchers from Eindhoven University of Technology. Quartz reports: Construction on the first home begins this year and five houses will be on the rental market by 2019, project organizers say. Within a week of releasing images of the new homes, 20 families expressed interest in dwelling in these postmodern pods, according to the project website. the project website. "The first aim of the project is to build five great houses that are comfortable to live in and will have happy occupants," developers say. Beyond that, they hope to promote 3D concrete printing science and technology so that printed housing "will soon be a reality that is widely adopted."

The "printer" in this case is a big robotic arm that will shape cement of a light, whipped-cream consistency, based on an architect's design. The cement is layered for strength. The project developers say that the consistency of this concrete and the precision of the printer will make it possible to mix and use only as much cement as is needed, which makes it environmentally-friendly and less expensive than classic construction methods. The printer and unique cement will also allow them to create unusual forms that challenge conventional notions of home design.

The jobs market has reached what should be some kind of inflection point: there are now more openings than there are workers. From a report: April marked the second month in a row this historic event has occurred, and the gap is growing. According to the monthly Job Openings and Labor Turnover Survey released this week, there were just shy of 6.7 million open positions in April, the most recent month for which data are available. That represented an increase of 65,000 from March and is a record. The number of vacancies is pulling well ahead of the number the Bureau of Labor Statistics counts as unemployed. This year is the first time the level of the unemployed exceeded the jobs available since the BLS started tracking JOLTS numbers in 2000. As of April, the total workers looking and eligible for jobs fell to 6.35 million, a decrease from 6.58 million the previous month. The number fell further in May to 6.06 million, though there is no comparable JOLTS data for that month. Under normal circumstances, the mismatch would be creating a demand for higher wages. However, average hourly earnings rose just 2.7 percent annualized in May, up one-tenth of a point from April. Further reading: Why Nebraska has an amazing jobs market but nobody is moving there.

Honolulu could become the first U.S. city to limit fares ride-hailing companies can charge when demand spikes, following a city council vote on Wednesday, the Honolulu Star-Advertiser newspaper reported. From a report: Ride-hailing companies such as Uber and Lyft use a model known as "surge pricing" in which the fare for a ride rises when factors such as rush hour and bad weather increase demand for the service. The practice could be limited in the future in Hawaii's largest city after the Honolulu City Council approved by a 6-3 vote a bill requiring city officials to cap surge pricing by ride-hailing companies, the newspaper reported. For the bill to become law, however, it still needs to be signed by the Mayor Kirk Caldwell, whose administration appears to oppose the measure, Hawaiinewsnow.com reported.
