CNN has a story about a slimy, gooey orange gel developed by British company D3O as far back as 1999 that is very soft and fluid-like normally, but that hardens immediately when it receives an impact: It's a gel that acts as both a liquid and a solid. When handled slowly the goo is soft and flexible but the moment it receives an impact, it hardens. It's all thanks to the gel's shock-absorbing properties... Felicity Boyce, a material developer at D3O, told CNN, "if you hit it with great force, it behaves more like a solid that's absorbing the shock and none of that impact goes through my hand."
American football has become a huge market for the British company, where the gel is incorporated in padding and helmets to absorb the impact of any hits a player receives. D3O claims it can reduce blunt impact by 53% compared to materials like foam. The material can also be put inside running shoes to improve performance and reduce the risk of foot injury. Usain Bolt ran with D3O gel insoles in his shoes at the 2016 Rio Olympics.
The material is being tested in body armor. "While we don't have a material that can stop a bullet, we do have a material that can reduce the amount of trauma that your body would experience if you got shot." There are also soft smartphone casings using the gel that harden when the phone is dropped and hits a hard surface.

More details are emerging about an online gamer whose fake call to Kansas police led to a fatal shooting:
"After phoning in a false bomb threat to a Glendale, California TV station in 2015, Tyler Barriss threatened to kill his grandmother if she reported him, according to local reports and court documents." -- The Wichita Eagle "The Glendale Police Department confirmed to ABC News that Tyler Barriss made about 20 calls to universities and media outlets throughout the country around the time he was arrested for a bomb threat to Los Angeles ABC station KABC in 2015... He was sentenced to two years and eight months in jail, court records show." -- ABC News "Within months of his release in August, he had already become the target of a Los Angeles Police Department investigation into similar hoax calls... LAPD detectives were planning to meet with federal prosecutors to discuss their investigation..." -- The Los Angeles Times The Wichita Eagle reports that even after the police had fatally shot the person SWauTistic was pretending to be, he continued his phone call with the 911 operator for another 16 minutes -- on a call which lasted over half an hour. Brian Krebs reports that police may have been aided in their investigation by another reformed SWAT perpetrator -- adding that SWauTistic privately claimed to have already called in fake emergencies at approximately 100 schools and 10 homes.
Just last month SWauTistic's Twitter account showed him bragging about a bomb threat which caused the evacuation of a Dallas convention center, according to the Daily Beast -- after which SWauTistic encouraged his Twitter followers to also follow him on a second account, "just in case twitter suspends me for being a god." Later the 25-year-old tweeted that "if you can't pull off a swat without getting busted you're not a leet hacking God its that simple."

Slashdot's Time-for-Bill-Gates department:
Long-time Slashdot reader theodp writes: Time invited Bill Gates to be the first guest editor in the 94-year history of the magazine. Among the news Bill deemed fit to print in Time's first augmented-reality-enhanced issue were articles by wife Melinda and pal Bono, both of whom graced the cover of Time with Bill as the 2005 Persons of the Year... Another article reveals that "the four learning hacks Bill Gates swears by" include Khan Academy (a $10+ million Gates Foundation partner), tech-backed Code.org (to which Bill, the Gates Foundation, Microsoft, and Steve Ballmer have given somewhere north of $17M), the Big History Project (to which Bill had contributed a "modest $10 million" as of 2014), and The Teaching Company (which got Bill stoked about Big History).
The issue also includes Gates' "four favorite ways to give back" and "six innovations that could change the world." In fact, the theme of the whole issue is "optimism," with 62-year-old Gates writing that "On the whole, the world is getting better. This is not some naively optimistic view; it's backed by data. Look at the number of children who die before their fifth birthday. Since 1990, that figure has been cut in half. That means 122 million children have been saved in a quarter-century, and countless families have been spared the heartbreak of losing a child."
Another optimistic essay came from Daily Show host Trever Noah, who writes, "Mock millennials all you want. Here's why they give me hope."

At least four pre-paid debit cards that accept cryptocurrencies abruptly suspended service on Friday. An anonymous reader quotes TheNextWeb:
Speaking to their customers on Twitter, the affected companies have said the move is the result of actions from their card issuer, [WaveCrest], who was acting on behalf of Visa Europe... A statement from Visa Europe obtained by The Daily Beast reporter Joseph Cox said the action was taken due to WaveCrest's "non-compliance" with VISA's membership regulations... In its statement, Visa makes clear that this isn't a crackdown on cryptocurrencies, but rather action against one company that broke its rules.
"All funds stored on cards are safe and will be returned to your Cryptopay accounts ASAP," one of the affected debit card companies assured users on Twitter, adding "Sorry for all the inconvenience caused..."
According to the article, "Some users on Twitter are reportedly stranded abroad without funds."

An anonymous reader quotes the official Rust blog:
The Rust team is happy to announce a new version of Rust, 1.23.0... New year, new Rust! For our first improvement today, we now avoid some unnecessary copies in certain situations. We've seen memory usage of using rustc to drop 5-10% with this change; it may be different with your programs...
The documentation team has been on a long journey to move rustdoc to use CommonMark. Previously, rustdoc never guaranteed which markdown rendering engine it used, but we're finally committing to CommonMark. As part of this release, we render the documentation with our previous renderer, Hoedown, but also render it with a CommonMark compliant renderer, and warn if there are any differences.
A few new APIs were also stabilized in this release -- see the complete release notes here -- and you no longer need to import the trait AsciiExt to provide ASCII-related functionality on u8, char, [u8], and str.
The Rust blog made another announcement earlier this week. "As open source software becomes more and more ubiquitous and popular, the Rust team is interested in exploring new and innovative ways to solicit community feedback and participation." So while defining Rust's roadmap for 2018, "we'd like to try something new in addition to the RFC process: a call for community blog posts for ideas of what the goals should be."

BrianFagioli writes: About 16 years ago, a for-pay Linux distribution caused quite a stir all because of its name -- Lindows. Yes, someone actually thought kicking the billion dollar hornets nest that is Microsoft by playing off of the "Windows" name was a good idea. To be honest, from a marketing perspective, it was brilliant -- it got tons of free press. Microsoft eventually killed the Lindows name by use of money and the legal system, however. Ultimately, the Linux distro was renamed "Linspire." Comically, there was a Lindows Insiders program way before Windows Insiders! After losing the Lindows name, the operating system largely fell out of the spotlight, and its 15 minutes of fame ended. After all, without the gimmicky name, it was hard to compete with free Linux distros with a paid OS. Not to mention, Richard Stallman famously denounced the OS for its non-free ways. The company eventually created a free version of its OS called Freespire, but by 2008, both projects were shut down by its then-owner, Xandros. Today, however, a new Linspire owner emerges -- PC/OpenSystems LLC. And yes, Lindows is rising from the grave -- as Freespire 3.0 and Linspire 7.0! "Today the development team at PC/Opensystems LLC is pleased to announce the release of Freespire 3.0 and Linspire 7.0. While both contain common kernel and common utilities, they are targeted towards two different user bases. Freespire is a FOSS distribution geared for the general Linux community, making use of only open source components, containing no proprietary applications. This is not necessarily a limitation : through our software center and extensive repositories, Freespire users can install any application that they wish," says PC/OpenSystems LLC. Back in 2003 the CEO of Lindows answered questions from Slashdot readers.
The first question was "Why oh why?"

An anonymous reader shares some new statistics from Laurie Voss, co-founder and COO of npm (the package manager/software registry for JavaScript):
The sum of all the package downloads in the npm Registry shows that the npm ecosystem continues to experience explosive, continuous growth... Right now, we estimate about 75% of all JavaScript developers use npm, and that number is rising quickly to reach 100%. We believe there are about 10 million npm users right now.
The first post in a three-part series graphs the popularity and growth rate for seven JavaScript frameworks.
Preact is tiny but the fastest-growing. Vue is also very fast growing and neck and neck with Ember, Angular and Backbone Ember has grown more popular in the last 12 months. Angular and Backbone have both declined in popularity. jQuery remains hugely popular but decreasingly so. React is both huge and very fast-growing for its size.

Slashdot's unknown-to-history department:
schwit1 shares the findings of a new study of 11,500-year-old bones: Sunrise girl-child ("Xach'itee'aanenh T'eede Gaay") lived some 11,500 years ago in what is now called Alaska, and her ancient DNA reveals not only the origins of Native American society, but reminds the world of a whole population of people forgotten by history millennia ago. "We didn't know this population existed," says anthropologist Ben Potter from the University of Alaska Fairbanks. "It would be difficult to overstate the importance of this newly revealed people to our understanding of how ancient populations came to inhabit the Americas." In a new study published this week, the team reports that a genetic analysis of sunrise girl-child's DNA shows she belonged to a forgotten people called the Ancient Beringians, unknown to science until now. Before now, there were only two recognized branches of early Native Americans (referred to as Northern and Southern). But when the researchers sequenced sunrise girl-child's genome -- the earliest complete genetic profile of a New World human to date -- to their surprise it matched neither.
Given the nature of this field of research -- and the scope of the new findings -- it's unlikely the new hypotheses will remain uncontested for long. But in the light of all the new evidence researchers are uncovering, it's clear the first settlers of America carried a more diverse lineage than we ever realized. "[This is] the first direct evidence of the initial founding Native American population," Potter says. "It is markedly more complex than we thought." The findings are reported in the journal Nature.

Slashdot's cease-and-desist department:
An anonymous reader quotes a report from The Verge: Amid vocal calls for the company to act, Twitter today offered its first explanation for why it hasn't banned President Donald Trump -- without ever saying the man's name. "Elected world leaders play a critical role in that conversation because of their outsized impact on our society," the company said in a blog post. "Blocking a world leader from Twitter or removing their controversial Tweets, would hide important information people should be able to see and debate. It would also not silence that leader, but it would certainly hamper necessary discussion around their words and actions." In its blog post, Twitter reiterated its previous statement that all accounts still must follow the company's rules. The statement seemed to leave open the possibility that it might one day take action against Trump's account, or the accounts of other world leaders who might use the platform to incite violence or otherwise break its rules. "We review Tweets by leaders within the political context that defines them, and enforce our rules accordingly," it said. In response to the claims that Twitter doesn't ban President Trump because he draws attention -- and ad revenue -- to the company, Twitter said: "No one person's account drives Twitter's growth, or influences these decisions. We work hard to remain unbiased with the public interest in mind."

Slashdot's final-frontier department:
An anonymous reader quotes a report from Ars Technica: A new NASA mission, the first to hitch a ride on a commercial communications satellite, will examine Earth's upper atmosphere to see how the boundary between Earth and space changes over time. GOLD stands for Global-scale Observations of the Limb and Disk, and the mission will focus on the temperature and makeup of Earth's highest atmospheric layers. Along with another upcoming satellite, called ICON, GOLD will examine how weather on Earth -- and space weather caused by the sun -- affects those uppermost layers. GOLD, which will inspect the ultraviolet radiation that the upper atmosphere releases, will also be the first to take comprehensive records of that atmospheric layer's temperature. The satellite carrying GOLD will orbit 22,000 miles (35,400 kilometers) above Earth in a geostationary orbit, which means GOLD will stay fixed with respect to Earth's surface as the satellite orbits and the world turns. GOLD will pay particularly close attention to Earth's thermosphere, which is the gas that surrounds the Earth higher than 60 miles (97 km) up, and the layer called the ionosphere, which forms as radiation from the sun strips away electrons from particles to create charged ions. And although solar flares and other interactions on the sun do have a strong impact on those layers, scientists are learning that Earth's own weather has an impact on the layers, too.

Slashdot's one-man-army department:
Motherboard reporter Lorenzo Franceschi-Bicchierai has interviewed Emily Crose, a former NSA hacker, who has built NEMESIS, an AI-powered program that can help spot symbols that have been co-opted by hate groups to signal to each other in plain sight. Crose, who has also moderated Reddit in the past, thought of building NEMESIS after the Charlottesville, Virginia incident last year. From the report: Crose's motivation is to expose white nationalists who use more or less obscure, mundane, or abstract symbols -- or so-called dog whistles -- in their posts, such as the Black Sun and certain Pepe the frog memes. Crose's goal is not only to expose people who use these symbols online but hopefully also push the social media companies to clamp down on hateful rhetoric online. "The real goal is to educate people," Crose told me in a phone call. "And a secondary goal: I'd really like to get the social media platforms to start thinking how they can enforce some decency on their own platforms, a certain level of decorum." [...] At a glance, the way NEMESIS works is relatively simple. There's an "inference graph," which is a mathematical representation of trained images, classified as Nazi or white supremacist symbols. This inference graph trains the system with machine learning to identify the symbols in the wild, whether they are in pictures or videos. In a way, NEMESIS is dumb, according to Crose, because there are still humans involved, at least at the beginning. NEMESIS needs a human to curate the pictures of the symbols in the inference graph and make sure they are being used in a white supremacist context. For Crose, that's the key to the whole project -- she absolutely does not want NEMESIS to flag users who post Hindu swastikas, for example -- so NEMESIS needs to understand the context. "It takes thousands and thousands of images to get it to work just right," she said.

Mike Murphy, writing for Quartz: Ford's cars are getting closer to driving themselves, but they still need humans to build them. And because people aren't quite as durable as robots, it's trying to make those jobs easier by developing a suit with Ekso Bionics that takes the stress out of working long hours on a car assembly floor. Ekes, founded in 2005 in California, builds exoskeletons, essentially robotic assistive systems that people strap into to make walking, lifting, and standing easier. It's worked with the US military to build suits for soldiers. The system Ekso developed with Ford, called the EksoVest, doesn't use any motors to make working on factory lines less stressful, and it's nothing like what you see in movies, as it simply uses hydraulics to redistribute weight so that workers can comfortably raise their arms above their heads for extended periods of time. The suit can be worn by anyone from 5 ft to 6 ft 4 inches tall, and can provide lift assistance up to 15 pounds per arm. Some assembly-line workers at the average Ford plant lift their arms 4,600 times a day -- or about 1 million times a year, the company said.
