Amazon Warehouse Collapse in Baltimore Leaves Two Dead (engadget.com) 135

An anonymous reader quotes Engadget: Amazon is grappling with tragedy at one of its warehouses this weekend. A 50-foot wall at the company's southeast Baltimore fulfillment center collapsed on the night of November 2nd in the midst of a large storm, killing two people. They worked for an external company, an Amazon official told the Baltimore Sun... The storm was a particularly violent one that had torn roofs off apartment buildings and collapsed a ceiling at a TJ Maxx store, injuring three people. Amazon was caught up in extreme weather that unfortunately led to fatalities.

Researchers Explore New Batteries To Power Electric Planes (technologyreview.com) 141

Can researchers built a new kind of battery powerful enough to fuel an electric airplane? MIT's Technology Review profiles a company co-founded by MIT materials science professor Yet-Ming Chiang: He and his colleague, Venkat Viswanathan, are taking a different approach to reach their next goal, altering not the composition of the batteries but the alignment of the compounds within them. By applying magnetic forces to straighten the tortuous path that lithium ions navigate through the electrodes, the scientists believe, they could significantly boost the rate at which the device discharges electricity. That shot of power could open up a use that has long eluded batteries: meeting the huge demands of a passenger aircraft at liftoff. If it works as hoped, it would enable regional commuter flights that don't burn fuel or produce direct climate emissions...

The initial plan is to develop a battery that could power a 12-person plane with 400 miles (644 kilometers) of range -- enough to make trips from, say, San Francisco to Los Angeles, or New York to Washington. In a second phase, they hope to enable an electric plane capable of carrying 50 people the same distance.... Last year, the company announced plans to deliver a line of "hybrid to electric" aircraft with room for 12 passengers in 2022. At launch, the company intends to offer a hybrid plane with a gas turbine and two battery packs capable of flying around 700 miles (1,127 kilometers), as well as an all-electric version with three battery packs and a range of less than 200 miles....But crucially, the plane itself is expected to feature an open architecture that allows owners to switch out these modules over time, enabling them to upgrade to better batteries developed in the future or shift from hybrid to all-electric operation.

About 2% of the world's CO2 emissions come from air travel, and it's one of the fastest-growing sources of greenhouse-gas pollution. "More than a dozen companies, including Uber, Airbus, and Boeing, are already exploring the potential to electrify small aircraft," the article points out, "creating the equivalent of flying taxis that can cover around 100 miles (161 kilometers) on a charge. The hope is that these one- or two-passenger vehicles -- in most cases envisioned as autonomous vertical takeoff and landing aircraft -- could shorten commutes, ease congestion, and reduce vehicle emissions."

But with less ambitious batteries, "these would largely replace car rides for the rich, not displace air travel."

Is Data Science For All the New Computer Science For All? (berkeley.edu) 51

UC Berkeley's fastest-growing class is their introduction to data science. (The Wall Street Journal calls it a combination of computer science and statistics "to mine the growing troves of data on everything from traffic patterns to the habits of social-media users.") But that's only the beginning. UC Berkeley plans to create a new Division of Data Science -- one of their biggest reorganizations in decades -- and this fall they even began offering a major in data science. "The division will enable students and researchers to tackle not just the scientific challenges opened up by pervasive data, but the societal, economic and environmental impacts as well."

"We need to consider the ethical implications of these technologies as they are being developed," says Data 8 instructor David Wagner -- "what does the world look like when decisions are made by algorithms rather than people, and how do we ensure that when we analyze data our decisions reflect not just numbers but the humans behind them?"

Slashdot reader theodp writes: With a reported 1,295 students enrolled this semester, Berkeley's Data 8: The Foundations of Data Science boasts even bigger numbers than Harvard's most popular course, the more traditionally CS-focused CS50, which saw 724 students enroll this Fall....

Berkeley's embrace of Data Science coincidentally comes as Code.org is giving kudos to partners Microsoft, Facebook, Google, and Amazon for helping it convince lawmakers and tens of thousands of educators that more traditional computer science is what's needed for the K-12 masses, including the adoption of a new AP Computer Science program for high school students (an AP CS version of CS50 was funded by Microsoft).

So, is Data Science for All the new Computer Science for All? And, if so, will U.S. schools be looking at a major case of buyer's remorse?

How New, Polite Linus Torvalds Points Out Bad Kernel Code (phoronix.com) 370

Linus Torvalds "has shown already for the new Linux 4.20~5.0 cycle he isn't relaxing his standards but is communicating better when it comes to bringing up coding," reports Phoronix, adding "So far it looks like Linus' brief retreat is paying off with still addressing code quality issues -- and not blatantly accepting new code into the kernel as some feared -- but in doing so in a professional manner compared to his past manner of exclaiming himself over capitalized sentences and profanity that at time put him at odds with some in the Linux kernel community."

AmiMoJo quotes their report: Last Saturday he took issue with the HID pull request and its introduction of the BigBen game controller driver that was introduced: the developer enabled this new driver by default. Linus Torvalds has always frowned upon random new drivers being enabled by default in the kernel configuration driver. [H]e still voiced his opinion over this driver's default "Y" build configuration, but did so in a more professional manner than he has done in the past:

We do *not* enable new random drivers by default. And we most *definitely* don't do it when they are odd-ball ones that most people have never heard of.

Yet the new "BigBen Interactive" driver that was added this merge window did exactly that.

Just don't do it.

Yes, yes, every developer always thinks that _their_ driver is so special and so magically important that it should be enabled by default. But no. When we have thousands of drivers, we don't randomly pick one new driver to be enabled by default just because some developer thinks it is special. It's not.... Please don't do things like this.

Phoronix also describes another "kernel oops" testing Torvalds' patience, in which Linus responded tactfully that "What makes me *very* unhappy about this is that if I'm right, I think it means that code was literally not tested at all by anybody who didn't have one of the entries in that list."

Billionaires Are Chasing The Holy Grail of Energy: Fusion (bloombergquint.com) 185

Long-time Slashdot reader Zorro shared this article from Bloomberg: Not long before he died, tech visionary Paul Allen traveled to the south of France for a personal tour of a 35-country quest to replicate the workings of the Sun. The goal is to one day produce clean, almost limitless energy by fusing atoms together rather than splitting them apart. The Microsoft Corp. co-founder said he wanted to view the early stages of the International Thermonuclear Experimental Reactor in Cadarache firsthand, to witness preparations "for the birth of a star on Earth." Allen wasn't just a bystander in the hunt for the holy grail of nuclear power. He was among a growing number of ultra-rich clean-energy advocates pouring money into startups that are rushing to produce the first commercially viable fusion reactor long before the $23 billion ITER program's mid-century forecast. Jeff Bezos, Bill Gates and Peter Thiel are just three of the billionaires chasing what the late physicist Stephen Hawking called humankind's most promising technology.

Scientists have long known that fusion has the potential to revolutionize the energy industry, but development costs have been too high for all but a handful of governments and investors. Recent advances in exotic materials, 3D printing, machine learning and data processing are all changing that. "It's the SpaceX moment for fusion," said Christofer Mowry, who runs the Bezos-backed General Fusion Inc. near Vancouver, Canada. He was referring to Elon Musk's reusable-rocket maker. "If you care about climate change you have to care about the timescale and not just the ultimate solution. Governments aren't working with the urgency needed."

The company Allen supported, TAE Technologies, stood alone when it was incorporated as Tri-Alpha Energy two decades ago. Now it has at least two dozen rivals, many funded by investors with a track record of disruption. As a result, there's been an explosion of discoveries that are driving the kind of competition needed for a transformational breakthrough, according to Mowry.

The article reports one fusion company founded last year by six MIT professors is "confident they'll be able to produce a prototype of a so-called net energy reactor by 2025."

Twitter Deletes Over 10,000 Bots That Discouraged US Midterm Voting (cnn.com) 177

Twitter has deleted over 10,000 disinformation bots discouraging Americans from voting in Tuesday's midterm elections.

An anonymous reader quotes CNN: Twitter said that the Democratic Congressional Campaign Committee had brought the accounts to their attention. "For the election this year we have established open lines of communication and direct, easy escalation paths for state election officials, DHS, and campaign organizations from both major parties," the spokesperson said. The company said it believes the network of accounts was run from the United States.
The 10,000 accounts were deleted in late September and early October, Reuters reports: The number is modest, considering that Twitter has previously deleted millions of accounts it determined were responsible for spreading misinformation in the 2016 U.S. presidential election. Yet the removals represent an early win for a fledgling effort... The DCCC launched the effort this year in response to the party's inability to respond to millions of accounts on Twitter and other social media platforms that spread negative and false information about Democratic presidential candidate Hillary Clinton and other party candidates in 2016, three people familiar with the operation told Reuters... The DCCC developed its own system for identifying and reporting malicious automated accounts on social media, according to the three party sources.

Have We Really Wiped Out 60 Percent of Animals? (theatlantic.com) 86

Remember that study which reported humanity had wiped out 60 percent of animal populations since 1970? The researchers' findings "have been widely mischaracterized," reports the Atlantic's science writer -- while adding that "the actual news is still grim."

The researchers had studied sample population estimates representing 4,000 of 63,000 known vertebrate species -- or 6.4 percent -- then performed a scientific extrapolation: Ultimately, they found that from 1970 to 2014, the size of vertebrate populations has declined by 60 percent on average. That is absolutely not the same as saying that humans have culled 60 percent of animals -- a distinction that the report's technical supplement explicitly states. "It is not a census of all wildlife but reports how wildlife populations have changed in size," the authors write. To understand the distinction, imagine you have three populations: 5,000 lions, 500 tigers, and 50 bears. Four decades later, you have just 4,500 lions, 100 tigers, and five bears (oh my). Those three populations have declined by 10 percent, 80 percent, and 90 percent, respectively -- which means an average decline of 60 percent. But the total number of actual animals has gone down from 5,550 to 4,605, which is a decline of just 17 percent.

For similar reasons, it's also not right that we have "killed more than half the world's wildlife populations" or that we can be blamed for "wiping out 60 percent of animal species" or that "global wildlife population shrank by 60 percent between 1970 and 2014." All of these things might well be true, but they're all making claims about metrics that were not assessed in the Living Planet Index... The average 60 percent decline across populations also obscures the fates of individual species. In the hypothetical scenario above, lions are still mostly fine, the tigers are in trouble, and the bears are on the brink of extinction. And of the species covered in the actual Living Planet Index, half are increasing in number, while only half are decreasing. This means that for those that are actually in decline, the outlook is even worse than it first appears.

The science writer also points out that vertebrates studied are vastly outnumbered by the millions of species of invertebrate, "which make up the majority of animal life..."

"None of this is to let humanity off the hook... At least a third of amphibians face extinction, thanks to climate change, habitat loss, and an apocalyptic killer fungus. "

Apple Used To Be an Inventor. Now It's Mainly a Landlord. (bloomberg.com) 205

An anonymous reader quotes a report from Bloomberg: For years, analysts and journalists watching Apple have talked up the growing importance of services, as opposed to hardware sales, to the company's top line. But it's only now that Apple's business model truly appears to be shifting toward collecting rent from the company's ecosystem and increasingly relying on gadget sales to perpetuate this rent rather than drive growth. Apple's decision to stop reporting iPhone unit sales underscores the shift. Services have been steadily growing in importance for Apple since 2016, while the share of revenue provided by the flagship gadget, the iPhone, has gone up and down depending on the popularity of different models.

There's a lot of potential for Apple to squeeze a higher rent directly out of its captive user base. Goldman Sachs estimates that only 10 percent of Apple's user base pay for iCloud Storage; in terms of price and service quality, iCloud has been a poor competitor to services provided by Google and some smaller companies such as Dropbox, but that only means Apple can increase revenue from it exponentially if it bothered to compete more aggressively, as it does with another key service, Apple Music. Even that streaming service has relatively low penetration, though, with only about 35 million users last year. Goldman Sachs predicts that number will grow to 83 million by 2020. Goldman's proposal for Apple is to create a services bundle similar to Amazon Prime; for $30 a month or so, subscribers would get access to music, video, 200 GB of storage and phone repair. The investment bank calculates that with just 50 million subscribers, such a bundle could add $18 billion in services revenue in 2019.
"Rent extraction from a user base that finds it hard to go away may sound a bit like extortion," Leonid Bershidsky writes in closing. "But it's more honest and upfront than extracting data from users in ways they often don't understand and then making money off the data, as Facebook does. That honesty is in itself a competitive advantage for Apple as it gradually reimagines itself as more of a services company."

The challenge, Bershidsky writes, "is to grow the services offering fast enough to make up for potential iPhone revenue losses; gadget prices cannot keep going up forever without hurting the top line, and in the end, a phone is just a phone. We only need it to gain access to all the nice digital stuff out there."

NASA, ESA Release First 8K Video From Space (engadget.com) 21

NASA and the European Space Agency have released the first 8K ultra high definition video filmed in space. It was shot with a RED Helium 8K camera and provides a glimpse of what the astronauts are working on aboard the International Space Station. Engadget reports: The camera was delivered to the ISS in April by a SpaceX cargo resupply mission, and the new video shows astronauts living aboard the ISS as they work and conduct experiments. Some of the experiments included in the video are the BEST investigation, which uses DNA sequencing to identify microbes in the space station; an experiment that compares plants grown in space to those grown on Earth; and the BCAT-CS study, which investigates the dynamic forces that exist between sediment particles. "We're excited to embrace new technology that improves our ability to engage our audiences in space station research," David Brady, assistant program scientist for the ISS Program Science Office at Johnson, said in a statement. "Each improvement in imagery fidelity brings that person on Earth closer to the in-space experience, allowing them to see what human spaceflight is doing to improve their life, as well as enable humanity to explore the universe."
