Solar Geoengineering 'Only Option' To Cool Planet Within Years, UN Says

著者: BeauHD
2023年3月4日 22:00
The United Nations Environment Program (UNEP) is investigating the potentials and dangers of solar geoengineering technologies, stating that these controversial interventions are humanity's "only option" to quickly cool the planet within years. An anonymous shares an excerpt from a Motherboard article: In a report published by UNEP in February, an independent panel describes what's currently known about so-called solar radiation modification, also called solar geoengineering, and concludes that, despite its great potential, it's not viable or even safe right now. Nonetheless, amid growing calls from governments to find an emergency brake for climate change -- and ongoing, independent efforts to develop solar geoengineering technology -- the UNEP is calling for a full-scale global review of the tech and eventual multinational framework for how it should be governed. The recommendations have some opponents fearing that this amounts to endorsement of adopting the technology -- a move that could create an even worse environmental crisis by messing with intertwined natural climate systems or pulling the focus away from mitigation measures, as well as further widening the inequalities that already exist as a result of climate change. Solar radiation modification describes a range of technologies that aim to cool our overheated planet by reflecting incoming sunlight back out into space, or making it easier for heat coming off the earth to escape. Blocking out just two percent of sunlight could, according to some estimates, totally offset the warming that comes from doubling the amount of CO2 in the atmosphere from pre-industrial levels. It's a tantalizing prospect, but comes with a raft of issues. For one, as the report notes, the best large-scale evidence we have that it could even work is from volcanic eruptions, where the smog cooled the globe for a couple of years afterwards. Most of the actual research has involved climate modeling, theoretical analyses or cost estimates. Some groups have conducted small-scale indoor experiments of how the tech might work. No one's taken the trials outdoors yet. Even if we knew more, it's not a be-all-end-all climate solution, said UNEP's chief scientist, Andrea Hinwood. "SRM technologies, should they be considered at some point in the future, do not solve the climate crisis because they do not reduce greenhouse gas emissions nor reverse the impacts of climate change. The world must be crystal clear on this point," she said in a UN media release. What solar geoengineering might do though, is buy the planet some time. The UNEP report highlights that even if we fully halted CO2 emissions right now, it could take at least until the end of the century to see a drop in temperature. "Make no mistake: there are no quick fixes to the climate crisis," wrote UNEP executive director Inger Andersen in the report. "Increased and urgent action to slash greenhouse gas emissions and invest in adapting to the impacts of climate change is immutable. Yet current efforts remain insufficient." Despite firm opposition from some, the message from the UNEP report seems to be to proceed with caution. "While UNEP is concerned, it is naive to think research will cease and the issues will disappear. We cannot afford to bury our heads in the sand," said chief scientist Hinwood.

Google has begun the process of bringing Chrome's full Blink browser engine to iOS against current App Store rules, and now we have our first look at the test browser in action. 9to5Google reports: In the weeks since the project was announced, Google (and Igalia, a major open source consultancy and frequent Chromium contributor) have been hard at work getting a simplified "content_shell" browser up and running in iOS and fixing issues along the way. As part of that bug fixing process, some developers have even shared screenshots of the minimal Blink-based browser running on an iPhone 12. In the images, we can see a few examples of Google Search working as expected, with no glaringly obvious issues in the site's appearance. Above the page contents, you can see a simple blue bar containing the address bar and typical browser controls like back, forward, and refresh. With a significant bit of effort, we were able to build the prototype browser for ourselves and show other sites including 9to5Google running in Blink for iOS, through the Xcode Simulator. As an extra touch of detail, we now know what the three-dots button next to the address bar is for. It opens a menu with a "Begin tracing" button, to aid performance testing. From these work-in-progress screenshots, it seems clear that the Blink for iOS project is already making significant progress, but it's clearly a prototype not meant to be used like a full web browser. The next biggest step that Google has laid out is to ensure this version of Blink/Chromium for iOS passes all of the many tests that ensure all aspects of a browser are working correctly.

Europe Pushing For Lunar Time Zone

With more lunar missions than ever on the horizon, the European Space Agency wants to give the moon its own time zone. The Associated Press reports: This week, the agency said space organizations around the world are considering how best to keep time on the moon. The idea came up during a meeting in the Netherlands late last year, with participants agreeing on the urgent need to establish "a common lunar reference time," said the space agency's Pietro Giordano, a navigation system engineer. "A joint international effort is now being launched towards achieving this," Giordano said in a statement. For now, a moon mission runs on the time of the country that is operating the spacecraft. European space officials said an internationally accepted lunar time zone would make it easier for everyone, especially as more countries and even private companies aim for the moon and NASA gets set to send astronauts there. [...] The international team looking into lunar time is debating whether a single organization should set and maintain time on the moon, according to the European Space Agency. There are also technical issues to consider. Clocks run faster on the moon than on Earth, gaining about 56 microseconds each day, the space agency said. Further complicating matters, ticking occurs differently on the lunar surface than in lunar orbit. Perhaps most importantly, lunar time will have to be practical for astronauts there, noted the space agency's Bernhard Hufenbach. "This will be quite a challenge" with each day lasting as long as 29.5 Earth days, Hufenbach said in a statement. "But having established a working time system for the moon, we can go on to do the same for other planetary destinations."

2 Drug Companies Can Legally Start Selling Cocaine, Heroin, and MDMA

2023年3月4日 12:30
An anonymous reader quotes a report from Motherboard: At least two companies in British Columbia, Canada, say they've received exemptions from the federal government allowing them to produce and distribute cocaine, heroin, MDMA, or magic mushrooms. But it's not clear under what circumstances the companies will be able to sell the drugs, and B.C. Premier David Eby said he was "astonished" to hear the announcement. On Thursday, Sunshine Earth Labs, a psychedelics manufacturer announced that Health Canada, a federal government agency, is allowing the company to legally produce and distribute the coca leaf and cocaine; MDMA; opium; morphine, heroin and psilocybin, the active ingredient in shrooms. The company said it plans to "bring a safer supply of drugs to the global market." Meanwhile, cannabis extractions company Adastra announced it's now legally allowed to both produce and distribute psilocybin and cocaine. In a statement to VICE News, Health Canada said Adastra is licensed to produce the drugs for scientific and medical purposes but cannot sell products to the general public. "They are only permitted for sale to other licence holders who have cocaine listed on their licence, pharmacists, practitioners, hospitals, or the holder of a section 56(1) exemption for research purposes," the agency said. Both companies claim they received amendments under Health Canada's Dealer's Licenses, which grant manufacturers, doctors, and researchers exemptions to the Controlled Drugs and Substances Act, allowing them to legally possess and make banned drugs. In a news conference, Eby said the licenses were granted without consultation from the province. "It is not part of our provincial plan," he said, noting that he would be following up with Health Canada about the announcements. Adastra said it's license allows it to "interact with up to 250 grams of cocaine and to import coca leaves to manufacture and synthesize the substance."

2023年3月4日 11:02
Mere weeks after achieving experimental airworthiness certification from the Federal Aviation Administration (FAA), Universal Hydrogen has successfully taken its 40-passenger regional hydrogen electric plane to the skies. Electrek reports: Universal Hydrogen is celebrating today following the first successful flight of the hydrogen electric plane this morning, which took off in Grant County, Washington, at 8:41 a.m. PST and flew for 15 minutes. For this initial flight, one of the airplane's engines was replaced with Universal Hydrogen's fuel cell-electric powertrain. The other standard engine remained to ensure the safety of the plane and its pilot, former US Air Force test pilot Alex Kroll. Kroll spoke to the confidence achieved during flight: "During the second circuit over the airport, we were comfortable with the performance of the hydrogen powertrain, so we were able to throttle back the fossil fuel turbine engine to demonstrate cruise principally on hydrogen power. The airplane handled beautifully, and the noise and vibrations from the fuel cell powertrain are significantly lower than from the conventional turbine engine." Connect has secured the first US order to convert 75 ATR 72-600 planes to Universal Hydrogen powertrains with the purchase rights for 25 more. With the first successful flight complete, Universal Hydrogen kicks off a two-year testing program that is expected to enable full certification for hydrogen electric passenger flights using the aforementioned ATR 72 planes by 2025. The flight also marks the Dash-300 flying test bed as the largest hydrogen electric plane to take flight, paving the way for more hydrogen electric conversions of existing aircraft. You can watch a video of the flight on YouTube or embedded in Electrek's article.

A popular app for 3D artists just received an accessible way to experiment with generative AI: Stability AI has released Stability for Blender, an official Stable Diffusion plug-in that introduces a suite of generative AI tools to Blender's free 3D modeling software. The Verge reports: The add-on allows Blender artists to create images using text descriptions directly within the software -- just like the Stable Diffusion text-to-image generator. You can also create images using existing renders, allowing you to experiment with various styles for a project without having to completely remodel the scene you're working on. Textures can similarly be generated using text prompts alongside reference images, and there's also the function to create animations from existing renders. The results for the latter are... questionable, even in Stability's own examples, but it's fun to play around with crudely transforming your projects into a video format. Stability for Blender is completely free and doesn't require any additional software or even a dedicated GPU to run. Providing you have the latest version of Blender installed, all you need to get Stable Diffusion running inside it is an internet connection and a Stability API key (which you can get directly from Stability AI). Installing the plug-in is relatively straightforward, and Stability has provided several tutorials to walk through how to use its various features.

2023年3月4日 09:45
Urban scooter company Lime sued Hertz Corp on Thursday alleging unfair competition and accusing the rental car giant of improperly hiring the startup's senior engineers. Reuters reports: San Francisco-based Neutron Holdings Inc, which does business as Lime, filed the lawsuit (PDF) in California federal court seeking unspecified monetary damages and an injunction "to recover and protect its trade secrets." It also named Charlie Fang, who previously was Lime's head of engineering, and another engineer as defendants. Lime claimed that Fang, who joined Hertz last year as a senior vice president, violated his employment agreement to not solicit former colleagues after leaving the company. Hertz said in a statement it "vehemently disagrees with the claims made in the lawsuit." The loss of engineers has "significantly harmed" Lime, which provides short-term e-bike and scooter rentals in about 30 countries. The company said in the lawsuit it now faces "staff shortages, recruiting costs, and critical project delays." Hertz sought to "capitalize" on Fang and his team's knowledge of building "back-end infrastructure for ride-sharing and consumer facing apps so that it could gain a competitive advantage over other companies," according to the complaint.

An anonymous reader quotes a report from Electrek: The Mississippi Senate has passed a bill that will stop electric car companies from opening their own dealerships in the state [...]. The bill started as House Bill 401, which you can see on the Mississippi Legislature's website. It amends Mississippi law related to car dealerships, clarifying that EV manufacturers can't get around the state's dealership laws, an exception that has been used by some manufacturers who have never opened a licensed dealer before. This will stop EV manufacturers from opening any physical locations in Mississippi. There is an exception in the law carved out for Tesla, which currently operates a single location in Brandon, Mississippi. "Mississippi has no statewide electric vehicle purchase incentive but does impose an annual $150 tax on electric vehicles, far above the amount of taxation that a hypothetical similarly efficient gas vehicle would have to pay," notes Electrek. "This charge is approximately equivalent to the amount of gas taxes a similarly efficient gas vehicle would pay if it drove 100,000 miles in a year."

Zoom has sacked its president, Greg Tomb, a former Google employee who only began working at the company around 10 months ago. Insider reports: Zoom said in a filing with the Securities and Exchange Commission that Tomb's termination was effective as of Friday. He will receive severance benefits in line with his employment arrangements, which are payable upon a "termination without cause," according to the SEC filing. The filing was signed off by Aparna Bawa, the chief operating officer at Zoom. It is unclear who will take over Tomb's position as president of Zoom. A spokesperson from Zoom told Insider the company won't find a replacement for Tomb and declined to comment further. Tomb's LinkedIn profile shows that he joined Zoom as president in June 2022. Before this, he worked at Google for more than a year as the vice president of sales for Google Workspace, Security, and Geo Enterprise. Tomb was also previously a president at software firm SAP and computer programming provider Vivido Labs, according to LinkedIn. He is a member of the board of Pure Storage, a tech company, his LinkedIn profile said.

Netflix Fights Attempt To Make Streaming Firms Pay For ISP Network Upgrades

著者: BeauHD
2023年3月4日 07:40
An anonymous reader quotes a report from Ars Technica: Netflix co-CEO Greg Peters spoke out against a European proposal to make streaming providers and other online firms pay for ISPs' network upgrades. "Some of our ISP partners have proposed taxing entertainment companies to subsidize their network infrastructure," Peters said in a speech Tuesday at Mobile World Congress in Barcelona (transcript). The "tax would have an adverse effect, reducing investment in content -- hurting the creative community, hurting the attractiveness of higher-priced broadband packages, and ultimately hurting consumers," he argued. [...] "ISPs claim that these taxes would only apply to Netflix. But this will inevitably change over time as broadcasters shift from linear to streaming," Peters said at MWC. Sandvine data suggests that nearly half of global Internet traffic is sent by Facebook, Amazon, Google, Apple, Netflix, and Microsoft. Online video accounts for 65 percent of all traffic, and Netflix recently passed YouTube as the top video-traffic generator. Peters cited Nielsen data showing that "Netflix accounts for under 10 percent of total TV time" in the US and UK while "traditional local broadcasters account for over half of all TV time." Live sports account for much of that. "As broadcasters continue the shift away from linear to streaming, they will start to generate significant amounts of Internet traffic too -- even more than streamers today based on the current scope and scale of their audiences," Peters said. "Broadband customers, who drive this increased usage, already pay for the development of the network through their subscription fees. Requiring entertainment companies -- both streamers and broadcasters -- to pay more on top would mean ISPs effectively charging twice for the same infrastructure." Telcos that receive new payments wouldn't be expected to lower the prices charged to home Internet users, Peters said. "As the consumer group BEUC has pointed out, there is no suggestion these levies would be passed onto consumers in the form of 'lower prices or better infrastructure,'" he said. Peters said Netflix's "operating margins are significantly lower than either British Telecom or Deutsche Telekom. So we could just as easily argue that network operators should compensate entertainment companies for the cost of our content -- exactly as happened under the old pay-TV model." While telcos claim companies like Netflix don't pay their "fair share," Peters pointed out that Netflix has spent a lot building its own network that reduces the amount of data sent over traditional telecom networks. "We've spent over $1 billion on Open Connect, our own content delivery network, which we offer for free to ISPs," he said. "This includes 18,000 servers with Netflix content distributed across 6,000 locations and 175 countries. So when our members press play, instead of the film or TV show being streamed from halfway around the world, it's streamed from around the corner -- increasing efficiency for operators while also ensuring a high-quality, no-lag experience for consumers." Peters also touted Netflix's encoding technology that cut bit rates in half between 2015 and 2020. While Internet traffic has increased about 30 percent a year, "ISPs have managed this increased consumer usage efficiently while their costs have remained stable," Peters said. "Regulators have highlighted this, too, calling out that infrastructure costs are not sensitive to traffic and that growing consumption will be offset by efficiency gains."

Amazon Pauses Construction On 2nd Headquarters In Virginia

2023年3月4日 07:00
Amazon is pausing construction of its second headquarters in Virginia following the biggest round of layoffs in the company's history and its shifting plans around remote work. The Associated Press reports: The Seattle-based company is delaying the beginning of construction of PenPlace, the second phase of its headquarters development in northern Virginia, Amazon's real estate chief John Schoettler said in a statement. He said the company has already hired more than 8,000 employees and will welcome them to the Met Park campus, the first phase of development, when it opens this June. "We're always evaluating space plans to make sure they fit our business needs and to create a great experience for employees, and since Met Park will have space to accommodate more than 14,000 employees, we've decided to shift the groundbreaking of PenPlace (the second phase of HQ2) out a bit," Schoettler said. He also emphasized the company remains "committed to Arlington" and the local region, which Amazon picked -- along with New York City -- to be the site of its new headquarters, known as HQ2, several years ago. More than 230 municipalities had initially competed to house the projects. New York won the competition by promising nearly $3 billion in tax breaks and grants, among other benefits, but opposition from local politicians, labor leaders and progressive activists led Amazon to scrap its plans there. In February 2021, Amazon said it would build an eye-catching, 350-foot Helix tower to anchor the second phase of its redevelopment plans in Arlington. The new office towers were expected to welcome more than 25,000 workers when complete. Amazon spokesperson Zach Goldsztejn said those plans haven't changed and the construction pause is not a result -- or indicative of -- the company's latest job cuts, which affected 18,000 corporate employees. Goldsztejn said the company is expecting to move forward with what he called pre-construction work on the construction in Virginia later this year, including applying for permits. He said final timing for the second phase of the project is still being determined. [...] Suzanne Clark, a spokeswoman for the Virginia Economic Development Partnership, said state officials are not concerned about Amazon filling its commitments. The total of 8,000 workers now employed at the new headquarters is already running about 3,000 ahead of what was expected at this point, she said. She said no incentive money has been paid out yet to Amazon.

CO2 Emissions May Be Starting To Plateau, Says Global Energy Watchdog

著者: msmash
2023年3月4日 06:22
Global carbon dioxide emissions are still rising but may at least be reaching a plateau, research from the International Energy Agency has shown. From a report: CO2 from energy -- by far the biggest source of emissions -- increased by less than 1% in 2022. This was despite the turmoil in energy the markets caused by Russia's invasion of Ukraine. The rise is smaller than the 6% increase in emissions from energy recorded by the IEA in 2021, a leap that came on the back of the rebound from the Covid-19 pandemic. However, a 7% reduction is needed every year to meet the goal of halving emissions this decade. Many experts had feared the soaring price of gas could push countries back towards using coal, which has much higher carbon emissions. But renewable energy seems to have been a big beneficiary, as countries opted for solar and wind power, and encouraged the take-up of heat pumps and electric vehicles (EVs). A mild start to Europe's winter also helped to save energy across the EU. Even a small increase in greenhouse gas emissions takes the world much further away from the path to net zero , the goal needed to limit global temperature rises to 1.5C above pre-industrial levels. Scientists have warned emissions need to fall by nearly half in this decade, if the world is to have a good chance of holding to the 1.5C limit.

A proposed law in Florida would force bloggers who write about Gov. Ron DeSantis and other elected officials to register with a state office and file monthly reports or face fines of $25 per day. The bill was filed in the Florida Senate Tuesday by Senator Jason Brodeur, a Republican. From a report If enacted, the proposed law would likely be challenged in court on grounds that it violates First Amendment protections of freedom of speech and the press. Defending his bill, Brodeur said, "Paid bloggers are lobbyists who write instead of talk. They both are professional electioneers. If lobbyists have to register and report, why shouldn't paid bloggers?" according to the Florida Politics news website. The bill text defines bloggers as people who write for websites or webpages that are "frequently updated with opinion, commentary, or business content." Websites run by newspapers or "similar publications" are excluded from the definition. The proposed registration requirements apply to bloggers who receive payment in exchange for writing about elected state officers, including "the Governor, the Lieutenant Governor, a Cabinet officer, or any member of the Legislature." Bloggers who write about a member of the legislature would have to register with the state Office of Legislative Services, while bloggers who write about the governor or other members of the executive branch would have to register with the Commission on Ethics.

Crypto Companies Behind Tether Used Falsified Documents and Shell Companies To Get Bank Accounts

In late 2018, the companies behind the most widely traded cryptocurrency were struggling to maintain their access to the global banking system. Some of their backers turned to shadowy intermediaries, falsified documents and shell companies to get back in, documents show. WSJ: One of those intermediaries, a major tether trader in China, was trying to "circumvent the banking system by providing fake sales invoices and contracts for each deposit and withdrawal," Stephen Moore, one of the owners of Tether Holdings, said in an email viewed by The Wall Street Journal. Mr. Moore said it was too risky to continue using the fake sales invoices and contracts, which he had signed, and recommended they abandon the efforts to open the accounts, the emails show. "I would not want to argue any of the above in a potential fraud/money laundering case," he wrote. Tether runs tether, the $71 billion stablecoin that is the most widely traded cryptocurrency, and a sister company runs Bitfinex, one of the world's largest crypto exchanges. Losing access to the banking system was "an existential threat" to their business, the companies said in a lawsuit. A cache of emails and documents reviewed by the Journal show a long-running effort to stay connected to the financial system. The companies often hid their identities behind other businesses or individuals. Using third parties occasionally caused problems, including hundreds of millions of dollars of seized assets and connections to a designated terrorist organization. Tether has been under investigation by the U.S. Justice Department, according to a person familiar with the matter. The investigation has been overseen by the Manhattan U.S. attorney's office.

Biden Administration Announces Plan To Stop Water Plant Hacks

2023年3月4日 03:01
The Biden administration announced on Friday a new plan to improve the digital defenses of public water systems. From a report: The move comes one day after the announcement of a national cybersecurity strategy by the White House, which seeks to broadly improve industry accountability over the cybersecurity of American critical infrastructure, such as hospitals and dams. The water system plan, which recommends a series of novel rules placing more responsibility for securing water facilities at the state-level, follows several high-profile hacking incidents in recent years. In February 2021, a cyberattack on a water treatment plant in Florida briefly increased lye levels in the water, an incident that could have been deadly if an alert worker had not detected the hack quickly. And in March 2019, a terminated employee at a Kansas-based water facility used his old computer credentials to remotely take systems offline, according to an administration official. The government is acting now because of the urgency of the threat, according to a senior U.S. Environmental Protection Agency (EPA) official. Radhika Fox, the assistant administrator in the EPA's Office of Water, said hackers had "shut down critical treatment processes" and "locked control system networks behind ransomware," underscoring the current danger. However, some experts say the new plan will not do enough to help make systems more secure.

New Disease Caused by Plastics Discovered in Seabirds

A new disease caused solely by plastics has been discovered in seabirds. The birds identified as having the disease, named plasticosis, have scarred digestive tracts from ingesting waste, scientists at the Natural History Museum in London say. From a report: It is the first recorded instance of specifically plastic-induced fibrosis in wild animals, researchers say. Plastic pollution is becoming so prevalent that the scarring was widespread across different ages of birds, according to the study, published in the Journal of Hazardous Materials. Young birds were found to have the disease, and it is thought chicks were being fed the plastic pollution by parents accidentally bringing it back in food. Scientists, including the Natural History Museum's Dr Alex Bond and Dr Jennifer Lavers, studied flesh-footed shearwaters from Australia's Lord Howe Island to look at the relationship between levels of ingested plastic and the proventriculus organ -- the first part of a bird's stomach. They found that the more plastic a bird had ingested, the more scarring it had. The disease can lead to the gradual breakdown of tubular glands in the proventriculus. Losing these glands can cause the birds to become more vulnerable to infection and parasites and affect their ability to digest food and absorb some vitamins.

Microsoft Unveils AI Model That Understands Image Content, Solves Visual Puzzles

Researchers from Microsoft have introduced Kosmos-1, a multimodal model that can reportedly analyze images for content, solve visual puzzles, perform visual text recognition, pass visual IQ tests, and understand natural language instructions. From a report: The researchers believe multimodal AI -- which integrates different modes of input such as text, audio, images, and video -- is a key step to building artificial general intelligence (AGI) that can perform general tasks at the level of a human. "Being a basic part of intelligence, multimodal perception is a necessity to achieve artificial general intelligence, in terms of knowledge acquisition and grounding to the real world," the researchers write in their academic paper, Language Is Not All You Need: Aligning Perception with Language Models. Visual examples from the Kosmos-1 paper show the model analyzing images and answering questions about them, reading text from an image, writing captions for images, and taking a visual IQ test with 22â"26 percent accuracy. [...] In this case, Kosmos-1 appears to be purely a Microsoft project, without OpenAI's involvement. The researchers call their creation a "multimodal large language model" (MLLM) because its roots lie in natural language processing, like a text-only LLM, such as ChatGPT. And it shows: For Kosmos-1 to accept image input, the researchers must first translate the image into a special series of tokens (basically text) that the LLM can understand.

San Diego Police Want To Add Surveillance Tech: 500 Streetlight Cameras Plus License Plate Readers

著者: msmash
2023年3月4日 01:09
San Diego Union-Tribune: Almost three years ago, the city of San Diego cut off access to its broad network of Smart Streetlights -- more than 3,000 devices perched atop light poles that could collect images and other data, some of which the Police Department used to solve criminal cases. The city removed that access, at least without a warrant, because of concerns from the public about surveillance and privacy issues. On Wednesday, the San Diego Police Department said it wants access to 500 of those devices to be restored -- and they want to add another crime-solving tool to the network: automated license plate readers. The controversy surrounding the Smart Streetlights began in 2019 when it was revealed that the cameras had been installed without public input. Police started accessing the camera footage in 2018 for investigations. Direct access was cut off in 2020 as a result of public outcry. Because the Smart Streetlight cameras had not been well maintained over the years, the city would need to install new cameras. Adding the license plate reader technology would mark the first time the city of San Diego would have the readers in fixed locations. This is the first big push for surveillance technology in San Diego since the city approved ordinances last year specifically setting rules to govern this kind of technology in light of privacy concerns.
