A main route between England and Wales was closed after a man climbed a bridge and flew a drone from the top. An anonymous reader shares a report: Traffic was stopped on the M48 -- the older of two Severn crossings -- because of "concern for welfare," police said. The man, in his 20s, came down voluntarily from the 47m (154ft) bridge tower and was arrested on suspicion of causing a public nuisance. Highways England said it was deeply concerned and that "a person has put their life at serious risk". "The incident was quickly spotted on our security cameras and reported to police and thankfully there was no injury or worse on this occasion," it said. "Appropriate security is in place on the bridge, we are liaising with Avon and Somerset Police and will be undertaking investigations to determine if any damage was caused during the incident." Police said: "Officers attended the M48 Severn Bridge at 08:10 this morning after concerns were raised for a man who appeared to have climbed one of the towers and was flying a drone off it."

Sony, the biggest maker of camera chips used in smartphones, is boosting production of next-generation 3D sensors after getting interest from customers including Apple. From a report: The chips will power front- and rear-facing 3D cameras of models from several smartphone makers in 2019, with Sony kicking off mass production in late summer to meet demand, according to Satoshi Yoshihara, head of Sony's sensor division. Sony's bullish outlook for 3D cameras provides much needed optimism to the global smartphone industry, which is suffering a slowdown as consumers find fewer reasons to upgrade devices. The Tokyo-based company has started providing software toolkits to outside developers so they can experiment with the chips and create apps that generate models of faces for communication or virtual objects for online shopping. "Cameras revolutionized phones, and based on what I've seen, I have the same expectation for 3D," said Yoshihara, who has worked for more than a decade on wider industry adoption of cameras in smartphones. "The pace will vary by field, but we're definitely going to see adoption of 3D. I'm certain of it."

Late last week, a team of about 50 scientists, drillers, and support staff successfully punched through nearly 4,000 feet of ice to access an Antarctic subglacial lake for just the second time in human history. From a report: On Friday, the Subglacial Antarctic Lakes Scientific Access (SALSA) team announced they'd reached Lake Mercer after melting their way through an enormous frozen river with a high-pressure, hot-water drill. The multi-year effort to tap into the subglacial lake -- one of approximately 400 scientists have detected across Antarctica -- offers a rare opportunity to study the biology and chemistry of the most isolated ecosystems on Earth. The only other subglacial lake humans have drilled into -- nearby Lake Whillans, sampled in 2013 -- demonstrated that these extreme environments can play host to diverse microbial life. Naturally, scientists are stoked to see what they'll find lurking in Lake Mercer's icy waters. "We don't know what we'll find," John Priscu, a biogeochemist at Montana State University and chief scientist for SALSA, told Earther via satellite phone from the SALSA drill camp on the Whillans Ice Plain. "We're just learning, it's only the second time that this has been done."

Russell Lewis, writing for NPR: When Nancy Grace Roman was a child, her favorite object to draw was the moon. Her mother used to take her on walks under the nighttime sky and show her constellations, or point out the colorful swirls of the aurora. Roman loved to look up at the stars and imagine. Eventually, her passion for stargazing blossomed into a career as a renowned astronomer. Roman was one of the first female executives at NASA, where she served as the agency's first chief of astronomy. Known as the "Mother of Hubble," for her role in making the Hubble Space Telescope a reality, Roman worked at NASA for nearly two decades. She died on Dec. 25 at the age of 93.

Roman fought to earn her place in a field dominated by men, paving the path for future female scientists. She was born in Nashville, Tenn. in 1925 and organized an astronomy club in fifth grade. She attended high school in Baltimore, where she requested to take a second year of algebra instead of a fifth year of Latin. When she made the appeal, she recounted in a 2017 interview with NPR that the guidance counselor wasn't supportive of her dream to become a scientist.

Her efforts helped lead to the creation of the Hubble Space Telescope. In her role at NASA, Roman developed and planned the Hubble Space Telescope, which is famous for its stunning images of space. Because of the Hubble Space Telescope, scientists have been able to collect data and gain insight into even the most remote galaxies of the universe. The success of the project led to future space telescopes. Roman's work, however, reached far beyond just the Hubble Space Telescope. In an interview with NASA, Roman once stated that one of the highlights of her career was when she discovered the first indication that common stars were not all the same age.

Apple has for years been a premium brand that rarely, if ever discounted products. Every year, the company could raise prices on products, and consumers would not only happily pay, but stand in long lines for the privilege of doing so. From a report: So when Apple started putting misleading, but seemingly consumer-friendly posters in front of Apple Stores at the end of 2018 offering a new iPhone model for $300 off (with trade-in of your current phone), you know something different happened for the company this year. Consumers fought back. Many analysts have reported that in the wake of poorer-than-expected sales for this year's crop of iPhones, Apple cut back on production, including on the $1,100 iPhone XS Max, the $999 iPhone XS and the XR, the "budget" model that replaced the previous entry-level new phone, the $349 SE. The price for the XR (the one Apple is hawking discounts for): $749.

"This should be a wakeup call for Apple," says Daniel Ives, an analyst with Wedbush Securities. "They swung, and they really missed." The prices on the new phones are "far too high," says Terry Walton, a tourist from Auckland, New Zealand. He has an iPhone 7 and didn't even consider any of the X-series iPhones because it still works just fine. Upgrading "didn't enter my mind at all," he says. It wasn't just iPhones that got price hikes. Apple also upped the cost of the top-of-the-line iPad to $1,000 as well (or over $2,800 for a loaded model) and added $300 to the cost of the Mac Mini and new MacBook Air computers.

Perhaps the most insightful piece that sums up why the U.S. and its allies are apprehensive of using Huawei's products. Six reasons, we are just highlighting the pointers, click on the source story to read the description:
1. There could be "kill switches" in Huawei equipment.
2. ... That even close inspections miss.
3. Back doors could be used for data snooping.
4. The rollout of 5G wireless networks will make everything worse.
5. Chinese firms will ship tech to countries in defiance of a US trade embargo.
6. Huawei isn't as immune to Chinese government influence as it claims to be.

schwit1 shares a report: Another year, another reason to take the promises of residential home batteries with a grain of salt. This month, a group of researchers from the University of California San Diego (UCSD) published a paper in Environmental Science and Technology reporting that there are very few cases in which operating a residential home battery reduces overall emissions -- assuming that households are economically rational and trying to minimize costs.

Of course, if the battery is only discharged during periods of peak emissions and only charged when fossil fuel use is low, then a household might reduce emissions. But across 16 representative regions, operating a battery this way ended up being costly. "There may be good reasons to decentralize the grid through ubiquitous installation of small RES [Residential Energy Storage], but cost-effective emissions control is not one of them at the moment," the researchers write.

The reputation of the meat industry will sink to that of big tobacco unless it removes cancer-causing chemicals from processed products such as bacon and ham, a coalition of experts and politicians in UK warn this week. From a report: Led by Professor Chris Elliott, the food scientist who ran the UK government's investigation into the horse-meat scandal, and Dr Aseem Malhotra, a cardiologist, the coalition claims there is a "consensus of scientific opinion" that the nitrites used to cure meats produce carcinogens called nitrosamines when ingested. It says there is evidence that consumption of processed meats containing these chemicals results in 6,600 bowel cancer cases every year in the UK -- four times the fatalities on British roads -- and is campaigning for the issue to be taken as seriously as sugar levels in food.

"Government action to remove nitrites from processed meats should not be far away," Malhotra said. "Nor can a day of reckoning for those who dispute the incontrovertible facts. The meat industry must act fast, act now -- or be condemned to a similar reputational blow to that dealt to tobacco." [...] In a statement issued today, the coalition warns "that not enough is being done to raise awareness of nitrites in our processed meat and their health risks, in stark contrast to warnings regularly issued regarding sugar and fattening foods."

In late 1966, a 29-year-old computer scientist drew a series of abstract figures on tracing paper and a quadrille pad. Some resembled a game of cat's cradle; others looked like heavenly constellations; still others like dress patterns. Those curious drawings were the earliest topological maps of what we now know as the internet. The doodler, Lawrence G. Roberts, died on Dec. 26 at his home in Redwood City, Calif. He was 81. The New York Times: The cause was a heart attack, said his son Pasha. As a manager at the Pentagon's Advanced Research Projects Agency, or ARPA, Dr. Roberts designed much of the Arpanet -- the internet's precursor -- and oversaw its implementation in 1969. Dr. Roberts called upon a circle of colleagues who shared his interest in computer networking for help in creating the technical underpinnings of the Arpanet, integrating and refining many ideas for how data should flow. Dr. Roberts was considered the decisive force behind packet switching, the technology that breaks data into discrete bundles that are then sent along various paths around a network and reassembled at their destination. He decided to use packet switching as the underlying technology of the Arpanet; it remains central to the function of the internet.

And it was Dr. Roberts's decision to build a network that distributed control of the network across multiple computers. Distributed networking remains another foundation of today's internet. Dr. Roberts's interest in computer networking began when he was a graduate student at the Massachusetts Institute of Technology in the early 1960s. He paid close attention to the work of his longtime colleague, Leonard Kleinrock, who had done research on theoretical aspects of computer networks, analyzing the problem of data flow. Dr. Roberts also followed the ideas of J.C.R. Licklider, a prominent psychologist and predecessor of Dr. Roberts's at ARPA, who envisioned what he called an "intergalactic computer network."

Some of the most popular apps for Android smartphones, including Skyscanner, TripAdvisor and MyFitnessPal, are transmitting data to Facebook without the consent of users in a potential breach of EU regulations. From a report: In a study of 34 popular Android apps, the campaign group Privacy International found that at least 20 of them send certain data to Facebook the second that they are opened on a phone, before users can be asked for permission. Information sent instantly included the app's name, the user's unique ID with Google, and the number of times the app was opened and closed since being downloaded. Some, such as travel site Kayak, later sent detailed information about people's flight searches to Facebook, including travel dates, whether the user had children and which flights and destinations they had searched for. European law on data-sharing changed in May with the introduction of General Data Protection Regulation and mobile apps are required to have the explicit consent of users before collecting their personal information.

The rarest bird in the world -- a species of duck called the Madagascar pochard -- has been given a new home in time for the new year. From a report: An international team of researchers released 21 of the birds at a lake in the north of Madagascar. It is a step towards the recovery of a species that just over a decade ago was thought to be extinct. Rescuing the species could also be a first step in protecting Madagascar's threatened wetlands. When it wasn't seen for 15 years, the Madagascar pochard was believed to have been wiped out completely. Then a tiny group of the birds was rediscovered in 2006 at one remote lake. These were the last 25 Madagascar pochards on the planet. Wetland habitats in the country have been so polluted and damaged that these few remaining birds had been forced into this last untouched area.

Corn and soybean crops have been good to farmers in the American Midwest and Plains. But these staple crops have taken a toll on the very earth they draw nourishment from. Now, a new generation of farmers is looking underground to try to replenish their soils in a way that both restores nutrients and reduces chemical runoff into the environment. From a report: "Mainstream agriculture, they just don't get it," says North Dakota farmer Jerry Doan. "You have got to feed the biology of the soil." Some farmers are experimenting with growing cover crops on their fields. Devoting valuable land to new crops can be risky for producers, whose thin margins make them reluctant to make big changes if their yields are going to fall, even temporarily. But in some communities, such as Washington County, Iowa, farmers are taking the leap together.

New York City police will deploy a camera-equipped drone above Times Square, along with new "counter-drone technology" blocking other devices from the area, where they expect as many as 2 million New Year's Eve revelers. From a report: The drone technology is the newest innovation developed by the largest U.S. police department as it prepares for an annual event that already features a broad array of anti-terrorism tactics. They will be used along with police airplanes and helicopters as surveillance tools, said Police Commissioner James O'Neill. Police and federal agents have worked with hotel staffs throughout the area in an effort to prevent an incident similar to the sniper who shot to death 59 outdoor concert-goers from a hotel room high above the Las Vegas strip on Oct. 1, 2017. O'Neill said authorities have no evidence of any credible threat of terrorism for New Year's Eve.

An anonymous reader shared a report: Sam Schreiber was mid-shampoo at a Drybar blow-dry salon in Los Angeles when someone from the front desk approached her stylist with an emergency: a woman was trying to pay for her blow-out with cash. "There was this beat of silence," says Ms. Schreiber, 33 years old. "She literally brought $40." More and more businesses like Drybar don't want your money -- the paper kind at least. It's making things awkward for those who come ill prepared. After all, you can't give back a hairdo, an already dressed salad or the two beers you already drank. The salad chain Sweetgreen has stopped accepting cash in nearly all its locations.

Most Dig Inns -- which serve locally sourced, healthy fast food -- won't take your bills either. Starbucks went cashless at a Seattle location in January, and at some pubs in the U.K., you can no longer get a pint with pound notes. The practice of not accepting cash has become popular enough to catch the attention of American lawmakers. [...] Despite the popularity of debit- and credit-card transactions, plenty of people do still pay for things with actual money. Cash represented 30% of all transactions and 55% of those under $10, according to a Federal Reserve survey of 2,800 people conducted in October 2017.

Here's an analysis by OverOps on how shared accountability affects the delivery of reliable software in a DevOps environment, and what are some of the top challenges teams face when it comes to building and maintaining quality applications. Conclusion from the report [PDF], which relies on a survey of over 2,000 IT professionals around the globe : At the center of this DevOps adoption chaos is the evolving relationship between development and operations. Many organizations are already taking a shared approach to accountability for application health, however they still lack the tools and application visibility needed to know who is ultimately responsible for addressing and fixing each issue. As the lines between these two teams continue to blur, organizations will need to focus on adopting tools that deepen visibility into their applications. Clarifying ownership of applications and services, and avoiding the "multiple owners = no owner" syndrome is a crucial for even the most bleeding edge organizations.

The "Dev vs. Ops: State of Accountability" survey revealed that as more organizations begin the transition to DevOps workflows, defining roles and processes becomes more difficult and more important. Furthermore, businesses of all sizes are building and releasing new code and application features faster than ever before, which adds additional pressure across the entire software delivery supply chain. Organizations going through the DevOps transformation are more likely to face visibility challenges that make it difficult to maintain or improve application quality and reliability.
