Global shutter sensors with no skew or distortion have been promised as the future of cameras for years now, but so far only a handful of products with that tech have made it to market. Now, Raspberry Pi is offering a 1.6-megapixel global shutter camera module to hobbyists for $50, providing a platform for machine vision, hobbyist shooting and more. From a report: The Raspberry Pi Global Shutter Camera uses a 6.3mm Sony IMX296 sensor, and requires a Raspberry Pi board with a CSI camera connector. Like other global shutter sensors, it works by pairing each pixel with an analog storage element, so that light signals can be captured and stored by all pixels simultaneously. By comparison, regular CMOS sensors read and store the light captured by pixels from top to bottom and left to right. That can cause diagonal skew on fast moving subjects, or very weird distortion on rotating objects like propellers.

Bing has crossed 100 million daily active users a month after the launch of its chatbot AI, according to Yusuf Mehdi, Microsoft's VP for Modern Life, Search and Devices. Engadget: He said the company is fully aware that it's still just "a small, low, single digit share player," but hey, there was a time when Bing wasn't even a part of the conversation.

Now, after the tech giant released its next-gen version, even those who haven't used it in the past are relying on it for their searches: Mehdi noted that one-third of Bing's daily active users are new to the search engine. "We see this appeal of the new Bing as a validation of our view that search is due for a reinvention and of the unique value proposition of combining Search + Answers + Chat + Creation in one experience," the VP said.

A SPAC merger brought a global "Uber for bus" startup to the Nasdaq just as tech investment was about to dry up. From a report: In July 2021 the world's tallest tower, the Burj Khalifa in Dubai, was briefly lit up in brilliant red, with animated electronic text scrolling up its height announcing "the Middle East's first $1.5 billion unicorn to list on Nasdaq." The splashy marketing was for Swvl, a company with lofty ambitions to become a hybrid of a ride-hailing app and bus service in cities across the globe. Twenty months later, the Dubai-based company's shares have dropped more than 99%. Its roughly $9 million market value is a shadow of the billion-dollar-plus valuation that once gave it so-called unicorn status.

A deal to buy Turkish transit company Volt Lines largely using Swvl shares fell apart in January. Once trumpeted by Dubai ruler Sheikh Mohammed bin Rashid Al Maktoum as a symbol of the Middle East's startup spirit, Swvl Holdings has become another example of tech-sector overreach -- and how quickly investor money dried up once superlow interest rates went away. It also shows the perils of trying to build a business that straddles emerging markets vulnerable to currency shocks as the dollar rises. Swvl was co-founded in Cairo in 2017 by former Rocket Internet SE executive Mostafa Kandil along with Ahmed Sabbah and Mahmoud Nouh. The trio started the company as a solution for commuters who didn't want to rely on public transit but couldn't pay a premium for ride-share services. Their idea: buses and vans running along routes that users could book a ride on with an app.

The U.S. Chamber of Commerce on Thursday called for regulation of artificial intelligence technology to ensure it does not hurt growth or become a national security risk, a departure from the business lobbying group's typical anti-regulatory stance. From a report: While there is little in terms of proposed legislation for AI, the fast-growing artificial intelligence program ChatGPT that has drawn praise for its ability to write answers quickly to a wide range of queries has raised U.S. lawmakers' concerns about its impact on national security and education.

The Chamber report argues policymakers and business leaders must quickly ramp up their efforts to establish a "risk-based regulatory framework" that will ensure AI is deployed responsibly. It added that AI is projected to add $13 trillion to global economic growth by 2030 and that it has made important contributions such as easing hospital nursing shortages and mapping wildfires to speed emergency management officials' response. The report emphasized the need to be ready for the technology's looming ubiquity and potential dangers.

A week away from the March 16 launch of Baidu's ChatGPT equivalent, employees at China's biggest search-engine operator said they are racing to meet the deadline with the chatbot still struggling to perform some basic functions. From a report: To develop the artificial-intelligence-powered chatbot, dubbed Ernie Bot, hundreds of people have been working around the clock, people familiar with the project said. Other teams have been asked to lend their staff and their powerful computer chips, which Chinese companies can no longer buy because of U.S. sanctions, they said. The AI model that is the basis of the chatbot is still being trained with data ahead of the scheduled launch, a highly anticipated event in China's tech industry, some of the people said. Some employees said they haven't had sufficient time to build a well-functioning product. Baidu plans to roll out the product in stages, first opening it up for public testing to a restricted pool of users, people briefed about the plan said. Last month, Baidu said that it will embed Ernie Bot into its search engine first and will open it to the public in March.

Chinese artificial intelligence groups are skirting export controls to access high-end US chips through intermediaries, revealing potential loopholes in Washington's blockade of cutting-edge technology to the country. From a report: AI surveillance groups targeted by US sanctions have found ways to obtain restricted technology by using cloud providers and rental arrangements with third parties, as well as purchasing the chips through subsidiary companies in China. iFlytek, a state-backed voice recognition company blacklisted by Washington in 2019, has been renting access to Nvidia's A100 chips, which are critical in the race to develop groundbreaking AI applications and services, according to two staffers with direct knowledge of the matter.

Facial recognition group SenseTime, sanctioned at the same time as iFlytek, has used intermediaries to purchase banned components from the US, according to three senior employees familiar with the situation. Privately controlled cloud computing companies also provide access to high-end US chips. AI-Galaxy, a Shanghai-based cloud computing company founded by former employees from Nvidia and AliCloud, charges $10 for one-hour access to eight of its A100 Nvidia chips. The ability of Chinese AI groups to continue accessing Nvidia's crucial high-end chips and other cutting-edge technology underlines the challenge the US faces in enforcing its trade restrictions against Chinese companies.

U.S. President Joe Biden's proposed budget, set to be unveiled Thursday, will include a provision to close tax loss harvesting on crypto transactions. From a report: A White House official confirmed that the budget will include a tax provision intended to reduce wash sales trading by crypto investors. At present, investors can sell any cryptocurrencies at a loss, claim the loss on their taxes and then buy the same amount and type of cryptocurrencies again. According to the Wall Street Journal, the provision would be expected to raise up $24 billion.

The president's proposed budget will lay out his fiscal priorities. White House officials told the Journal the plan would lower the U.S. deficit by $3 trillion over the next 10 years. Any budget would need passage through the House of Representatives and the Senate before going to the president's desk for his signature.

An anonymous reader quotes a report from Motherboard: A security researcher appears to have tracked the physical location of a former top Biden administration official through his apparent usage of AllTrails, a popular hiking app with more than 30 million registered users. The AllTrails records appear to show the official visiting sensitive locations such as the White House, and also suggests the specific house where he or his family lives. By default, AllTrails users' activity is public for anyone to view, including completed trails, maps, and activities. But that convenience and focus on providing a social network style experience comes with potential risks around national security or privacy, depending on the particular user. Whether a public figure like a government official or celebrity, or someone at risk of stalking in general such as someone in an abusive relationship, AllTrails' privacy settings may be something users should consider.

"I found interesting results by searching near the Pentagon, NSA, CIA or White House and then looking at the user's other activity," Wojciech, the security researcher, told Motherboard in an email. Wojciech said they used their own open source intelligence platform as part of the investigative process. They said the tool supports Strava and another app called SportsTracker, and will include AllTrails itself soon. Wojciech sent Motherboard a link to what they believed to be the AllTrails profile of the former top Biden official. Motherboard is not naming the official because they did not respond to requests for comment, and their profile is still publicly accessible.

One trip to the White House in December recorded in AllTrails also shows a nearby apartment building he ended his journey at. More trips recorded that month show the official's other movements throughout Washington D.C. Much of the AllTrails activity relates to when this official was part of the administration. Motherboard searched through the official's AllTrails activity and found multiple hikes starting from the same location. Motherboard then queried public records and found this location was a house registered to the official's family, meaning AllTrails had helped identify where the official or his family may have been living. Motherboard also verified that the official does have an account on AllTrails by attempting to sign up to the service with the official's personal email address. This was not possible because the address was already registered to an account.

Scientists have created mice with two biological fathers by generating eggs from male cells, a development that opens up radical new possibilities for reproduction. The Guardian reports: The advance could ultimately pave the way for treatments for severe forms of infertility, as well as raising the tantalizing prospect of same-sex couples being able to have a biological child together in the future. "This is the first case of making robust mammal oocytes from male cells," said Katsuhiko Hayashi, who led the work at Kyushu University in Japan and is internationally renowned as a pioneer in the field of lab-grown eggs and sperm. Hayashi, who presented the development at the Third International Summit on Human Genome Editing at the Francis Crick Institute in London on Wednesday, predicts that it will be technically possible to create a viable human egg from a male skin cell within a decade. Others suggested this timeline was optimistic given that scientists are yet to create viable lab-grown human eggs from female cells.

The study, which has been submitted for publication in a leading journal, relied on a sequence of intricate steps to transform a skin cell, carrying the male XY chromosome combination, into an egg, with the female XX version. Male skin cells were reprogrammed into a stem cell-like state to create so-called induced pluripotent stem (iPS) cells. The Y-chromosome of these cells was then deleted and replaced by an X chromosome "borrowed" from another cell to produce iPS cells with two identical X chromosomes. "The trick of this, the biggest trick, is the duplication of the X chromosome," said Hayashi. "We really tried to establish a system to duplicate the X chromosome."

Finally, the cells were cultivated in an ovary organoid, a culture system designed to replicate the conditions inside a mouse ovary. When the eggs were fertilized with normal sperm, the scientists obtained about 600 embryos, which were implanted into surrogate mice, resulting in the birth of seven mouse pups. The efficiency of about 1% was lower than the efficiency achieved with normal female-derived eggs, where about 5% of embryos went on to produce a live birth. The baby mice appeared healthy, had a normal lifespan, and went on to have offspring as adults. "They look OK, they look to be growing normally, they become fathers," said Hayashi. He and colleagues are now attempting to replicate the creation of lab-grown eggs using human cells.

sciencehabit shares a report from Science Magazine: Has the quest for room temperature superconductivity finally succeeded? Researchers at the University of Rochester (U of R), who previously were forced to retract a controversial claim of room temperature superconductivity at high pressures, are back with an even more spectacular claim. This week in Nature they report a new material that superconducts at room temperature -- and not much more than ambient pressures. "If this is correct, it's completely revolutionary," says James Hamlin, a physicist at the University of Florida who was not involved with the work. A room temperature superconductor would usher in a century-long dream. Existing superconductors require expensive and bulky chilling systems to conduct electricity frictionlessly, but room temperature materials could lead to hyperefficient electricity grids and computer chips, as well as the ultrapowerful magnets needed for levitating trains and fusion power. [...]

On February 22, [physicist Ranga Dias] and his colleagues doubled down on their original claim. In a preprint posted on arXiv they reported synthesizing a new version of CSH that superconducts at a slightly lower 260 K, but at only about half the previous pressure. "This should clear up any questions regarding CSH," says co-author Russell Hemley, an x-ray crystallographer at the University of Illinois, Chicago, who helped determine the material's structure. Now comes the even more promising substance: nitrogen-doped lutetium-hydride (LNH). To make it, Dias's team loaded a thin lutetium foil in a diamond vise and injected a mix of hydrogen and nitrogen gas. By ramping the pressure up to 2 gigapascals (nearly 20,000 times atmospheric pressure) and baking the mix at 200C for up to 3 days, they forged a bright blue crystalline fleck, one that survived even after the pressure was eased.

When they dialed the pressure back up to as little as 0.3 gigapascals, the blue fleck turned pink as the electrical resistance plunged to zero. The substance reached a peak superconducting temperature of 294 K-7-degrees warmer than the original CSH and truly room temperature -- at pressures of 1 gigapascal. Magnetic measurements also showed the sample repelled an externally applied magnetic field, a hallmark of superconductors. The paper, the authors say, went through five rounds of review. Given the U of R group's recent retraction, many physicists won't be easily convinced. "I think they will have to do some real work and be really open for people to believe it," Hamlin says. Jorge Hirsch, a physicist at the University of California, San Diego, and a vociferous critic of the earlier work, is even more blunt. "I doubt [the new result], because I don't trust these authors."

schwit1 shares an excerpt from a Substack article, written by former cybersecurity reporter Catalin Cimpanu: The Canada Revenue Agency (CRA), the tax department of Canada, recently updated its terms and conditions to force taxpayers to agree that CRA is not liable if their personal information is stolen while using the My Account online service portal -- which, ironically, all Canadians must use when doing their taxes and/or running their business. The CRA's terms of use assert the agency is not liable because they have "taken all reasonable steps to ensure the security of this Web site."

Excerpt from the CRA terms statement: "10. The Canada Revenue Agency has taken all reasonable steps to ensure the security of this Web site. We have used sophisticated encryption technology and incorporated other procedures to protect your personal information at all times. However, the Internet is a public network and there is the remote possibility of data security violations. In the event of such occurrences, the Canada Revenue Agency is not responsible for any damages you may experience as a result."

Unfortunately, that is not true. After reviewing the HTTP responses from the CRA My Account login page, it's clear the agency has not configured even some of the most basic security features. For example, security protections for their cookies are not configured, nor are all the recommended security headers used. Not only is that not "all reasonable steps," but the CRA is missing the very basics for securing online web applications.

The terms of use also state that users are not allowed to use "any script, robot, spider, Web crawler, screen scraper, automated query program or other automated device or any manual process to monitor or copy the content contained in any online services." Looking at the HTTP response headers using web browser developer tools doesn't breach the terms of services, but the CRA must be well aware that internet users perform scans like this all the time. And it's not the legitimate My Account users who are likely to be the culprits. Unfortunately for Canadians, threat actors don't read terms of use pages. A statement like this doesn't protect anyone, except CRA, from being held responsible for failing to properly secure Canadian citizens' personal data.

Silvergate Capital, the publicly-traded parent of Silvergate Bank, said Wednesday that it would liquidate the bank, just days after saying future operations would be uncertain. Axios reports: "In light of recent industry and regulatory developments, Silvergate believes that an orderly wind down of Bank operations and a voluntary liquidation of the Bank is the best path forward," a press statement reads. While the bank's demise had everything to do with its choice of industry -- FTX's collapse sent the entire crypto world in hunt of liquidity, causing a run on deposits at Silvergate -- balance-sheet problems in today's high-rate environment is not a crypto bank-specific stumbling block. Silvergate's troubles were in plain sight in that respect.

When customers pulled more than $8 billion from its platform late last year, the bank got a $4.3 billion assist in home loan advances from the Federal Home Loan Bank (FHLB). It effectively benefited from an implicit government backstop. But between having to pay those loans back right away and other investment losses, its outlook was grim, even before the company filed a registration statement saying so.

The overwhelming majority of bank liquidations are announced on a Friday afternoon, to give the FDIC a full weekend to shore up the institution and reassure depositors before the next business day. The fact this happened on a Wednesday is an indication of just how quickly Silvergate imploded. "Crypto exchanges, platforms and stablecoin issuers at least have the excuse that they don't have direct access to central bank liquidity," Frances Coppola, an economist and writer of blog Coppola Comment, said in a recent post about the bank. "But Silvergate does -- and yet it didn't use it." That would appear to be an oversight for the bank, but also its regulator.

Last month, Volkswagen garnered plenty of bad publicity when it emerged that the company's connected car service refused to help track a stolen car -- with a 2-year-old child still on board -- until someone paid to reactivate the service. Now, the automaker says it's very sorry this happened, and it's making its connected vehicle emergency service free to most model-year 2020-2023 Volkswagens. Ars Technica reports: "The family was thankfully reunited, but the crime and the process failure are heartbreaking for me," said Rachael Zaluzec, VW's SVP for customer experience and brand and marketing. "As a mom and an aunt, I can imagine how painful this incident must have been. Words can't adequately express how truly sorry I am for what the family endured."

"Volkswagen must and will do better for everyone that trusts our brand and for the law enforcement officials tasked with protecting us. In addition to a full investigation of what went wrong and actions taken to address the failure, we want to make it right for the future. Today, we are setting a new standard for customer peace of mind. As of June 1, we will make these connected vehicle emergency services free for five years as one significant step we can take as a commitment to our owners and their families," Zaluzec said in a statement sent to Ars.

Most MY2020 or newer VWs can use connected services, apart from MY2020 Passats. From June, owners can sign up for five years of free Car-Net Safe and Secure, which uses the vehicle's onboard modem to connect to the emergency services via the car's SOS button. In gasoline-powered VWs, there is also an anti-theft alert. VW says it will make Car-Net Remote Access free for five years as well. This lets owners interact with their car via a mobile app and can lock and unlock the doors, honk the horn and flash the lights, and, if fitted, remote-start the vehicle.

An anonymous reader quotes a report from Politico: The Dutch government confirmed for the first time Wednesday it will impose new export controls on microchips manufacturing equipment, bowing to U.S. pressure to block the sale of some of its prized chips printing machines to China. The U.S. and the Netherlands reached an agreement to introduce new export restrictions on advanced chip technology to China at the end of January, but until now, the Dutch government hadn't commented publicly on it. The deal, which also included Japan, involves the only three countries that are home to manufacturers of advanced machines to print microchips. It is a U.S.-led initiative to choke off the supply of cutting-edge chips to China.

"Given the technological developments and geopolitical context, the government has concluded that it is necessary for the (inter)national security to expand the existing export controls on specific manufacturing equipment for semiconductors," Foreign Trade Minister Liesje Schreinemacher wrote in a letter to Dutch lawmakers published Wednesday evening. The Dutch government wants to prevent Dutch technology from being used in military systems or weapons of mass destruction, Schreinemacher wrote — echoing the U.S. reasoning when it imposed its own export controls in October. The Netherlands also wants to avoid losing its pole position in producing cutting-edge chip manufacturing tools: Schreinemacher said the government wants to uphold "Dutch technological leadership." While China is not explicitly named in Schreinemacher's letter, the new policy is targeted at Chinese efforts to overtake the U.S. and others like Taiwan, South Korea, Japan and leading European countries in the global microchips supply chain.

The new export restrictions deal a blow to ASML, the global leader in producing advanced microchips printing machines based in Veldhoven, in southern Netherlands. In the letter, Schreinemacher said the new export control measures include the most advanced deep ultraviolet (DUV) machines, which are part of ASML's advanced chips printers portfolio. The Dutch firm, which is the highest-valued tech company in Europe, already did not receive export licenses for selling its most advanced machines using extreme ultraviolet light (EUV) technology to China since 2019. ASML in a statement confirmed it will now "need to apply for export licenses for shipment of the most advanced immersion DUV systems," but it noted it has not yet received more details about what "most advanced" means.
