Michael Kan, writing for PCMag: NZXT is a popular PC desktop case vendor, but the California-based company recently had to raise its prices. The reason? The new US tariffs on Chinese imports includes PC cases. In September, the Trump administration imposed the 10 percent duty, which also cover motherboards, graphics cards, and CPU coolers from the country. As a result, NZXT had to introduce a 10 percent price increase on PC cases to deal with the added costs, VP Jim Carlton told PCMag in an interview.

And building a PC could get even more expensive in 2019; US tariffs on Chinese-made goods will rise from 10 percent to 25 percent in January. "If I needed to build a system in the next six months, I'd definitely build it before the end of the year," Carlton told us. For PC builders, the tariffs risk adding a few hundred dollars to the total cost of components for a custom desktop. "If it's a $2,000 purchase on 25 percent tariffs, it's going to be a $2,500 purchase," Carlton said. "So we are very concerned with the direction of where this is going. I don't have a 10 percent [profit] margin I can just throw away and absorb the tariffs," he added. "And certainly no one has a margin for 25 percent."

Netflix says it plans to begin testing lower-priced subscription in some markets in a bid to see if it will help the company boost the number of subscribers, CEO Reed Hastings told Bloomberg. The company has not identified the markets where it will be testing the lower-priced subscription, and has not clarified how soon it intends to conduct these tests. The company will likely consider Asian markets where it is having a tough time gaining the market share against local services that are much aggressively priced.

Ed Yong, writing for The Atlantic: For many people, a two-and-a-half-minute video of a baby brown bear trying to scale a snow-covered mountain was a life-affirming testament to the power of persistence. As it begins, the cub is standing with its mother on the side of a perilously steep ridge. The mother begins walking across, and despite slipping a few times on the loose snow, she soon reaches the top. Her cub, following tentatively after her, isn't so fortunate. It loses its footing and slides several feet. It pulls itself together and reattempts the ascent, before slipping again.

Finally, the cub nears the top. But as the footage zooms in to focus on the moment of reunion, the mother inexplicably swipes at the youngster with her paw, sending it hurtling downward again. It slides a long way, scrabbling for purchase and finding some just before it hits a patch of bare rock. Once again, it starts to climb, and after what seems like a nail-biting eternity for anyone watching, it reaches its mother. The two walk away.

The video was uploaded to the ViralHog YouTube channel on Friday, and after being shared on Twitter, it rapidly went viral. At the time of this writing, it has been watched 17 million times. The cub's exploits were equal parts gif, nature documentary, and motivational poster. It had all the elements of an incredible story: the most adorable of protagonists, rising and falling action (literally), and a happy ending. It was a tale of tenacity in the face of adversity, triumph against the odds. But when biologists started watching the video, they saw a very different story.

The video, they say, was clearly captured by a drone. And in it, they saw the work of an irresponsible drone operator who, in trying to film the bears, drove them into a dangerous situation that almost cost the cub its life. "I found it really hard to watch," says Sophie Gilbert, an ecologist at the University of Idaho who studies, among other things, how drones affect wildlife. "It showed a pretty stark lack of understanding from the drone operator of the effects that his actions were having on the bears." (It wasn't just scientists, either; several drone pilots were also dismayed by the footage.)

In a fireside chat in New Delhi, India, Twitter CEO Jack Dorsey said Monday the "follower count" metric on the social platform is meaningless. Talking in front of a live audience, the Twitter co-founder said it was probably unwise to include and emphasize on the follower count on his social network, a move he said the company did not realize while implementing it back in the day. "Back then, we were not really thinking about all the dynamics that could ensue afterwards," he said.

"One of the things we did was we had people follow each other -- so you can be a follower of someone," Dorsey said, explaining the thinking that went into carving some of the core features of Twitter. The company listed the number of people you had, and "made the font size a little bit bigger than everything else on the page. We did not really think much about it and moved on to the next problem to solve. What that has done is we put all the emphasis, not intending to, on that number of how many people follow me. So if that number is big and bold, what do people want to do with it? They want to make it go up."

"So when you open Twitter and you see that number is five. It is actually incentivizing you to increase that number. That may have been right 12 years ago, but I don't think it is right today. I don't think that's the number you should be focused on. I think what is more important is the number of meaningful conversations you're having on the platform. How many times do you receive a reply?"

Dorsey's remarks comes as he has publicly acknowledged that the company is rethinking about some of the core features of Twitter. late last month, a report claimed that Twitter was also thinking about discontinuing the "likes" feature -- Twitter neither confirmed nor denied it. On Monday, Dorsey reaffirmed that focusing on number of likes and retweets is not healthy.

Dorsey is not the only Twitter co-founder who has, of late, shown disdain for the follower count. Last week, Ev Williams expressed a similar sentiment. "I think showing follower counts was probably ultimately detrimental. It really put in your face that the game was popularity," he said at a conference.

Prime Minister Justin Trudeau told a press freedom event in Paris Sunday that one of the bulwarks protecting democratic governments from being undermined is also an institution under stress -- a free-thinking, robust media. From a report: "If a democracy is to function you need an educated populace, and you need to have an informed populace, ready to make judicious decisions about who to grant power to and when to take it away," Trudeau said. "When citizens cannot have rigorous analysis of the exercise of the power that is in their name and they have granted, the rest of the foundation of our democracies start to erode at the same time as cynicism arises." The press freedom advocacy organization Reporters Without Borders has developed a six-page international declaration on information and democracy to establish basic principles for the "common good of mankind." The organization hosted a small event on the sidelines of the Paris Peace Forum late Sunday afternoon where five presidents and prime ministers, including Trudeau, offered endorsements for this declaration. The Paris Peace Forum, intended to be an annual gathering of political, business and civil society leaders to explore peaceful solutions to the world's problems, was hosted by French President Emmanuel Macron to coincide with this weekend's events marking the centenary of the armistice agreement that ended the First World War.

Trudeau, addressing the audience at the press freedom event without a prepared text, also talked about the risk if too many citizens become too cynical about public institutions. "Attacks on the media are not just about getting your preferred political candidate elected," he said. "They're about increasing the level of cynicism that citizens have toward all authorities, toward all of the institutions that are there to protect us as citizens." Citizens are feeling "very real anxiety," Trudeau said, because their jobs are transforming as globalization increases competition around the world. When that anxiety is exacerbated, it undermines trust in institutions and increases cynicism. "One of the bulwarks against that, and one of the institutions that is most under stress right now, is a free-thinking, independent, rigorous, robust, respected media," the prime minister said.

The Chinese government doesn't want children playing games for several hours every day. It said as much in a public notice from August. Now, Tencent is going along with that recommendation. The world's biggest gaming company started pushing out its new "real name identity system" (RNIS) across China on November 1, according to market intelligence firm Niko Partners. From a report: This program aims to mitigate concerns about addiction and myopia in children. It limits people 12 and younger to an hour of gaming per day. And it forces every player to register themselves in the game with their real name and government ID. Of course, this program isn't new. Tencent introduced a version of its RNIS in May 2017. That also required players to register their age, but it was easy to fool. In September, however, the publisher revised and strengthened the program. And the government also stepped in to help. Regulators are providing Tencent with access to a massive list of every person who lives in China.

While the European Union has worked hard to strengthen its copyright laws in recent years, one country in the heart of the continent chooses its own path. Switzerland is not part of the EU, which means that its policies deviate quite a bit from its neighbors. According to Hollywood, that's not helping creators. From a report: Responding to recent submission to the United States Trade Representative (USTR), the MPAA has identified several foreign "trade barriers" around the world. In Hollywood's case, many of these are related to piracy. One of the countries that's highlighted, in rather harsh terms, is Switzerland. According to the MPAA, the country's copyright law is "wholly inadequate" which, among other things, makes it "extremely attractive" to host illegal sites. "Switzerland's copyright law is wholly inadequate, lacking crucial mechanisms needed for enforcement in the digital era," MPAA writes. [...] The European country has plans to update its laws, but the proposed changes are not significant improvements, Hollywood's trade group notes.

Your phone knows where you shop, where you work and where you sleep. Hedge funds are very interested in such data, so they are buying it. From a report: When Tesla Chief Executive Elon Musk said the car maker would work around the clock to boost production of its Model 3 sedan, the number crunchers at Thasos Group decided to watch. They circled Tesla's 370 acres in Fremont, Calif., on an online map, creating a digital corral to isolate smartphone location signals that emanated from within it. Thasos, which leases databases of trillions of geographic coordinates collected by smartphone apps, set its computers to find the pings created at Tesla's factory, then shared the data with its hedge-fund clients [Editor's note: the link may be paywalled; alternative source], showing the overnight shift swelled 30% from June to October.

Last month, many on Wall Street were surprised when Tesla disclosed a rare quarterly profit, the result of Model 3 production that had nearly doubled in three months. Shares shot up 9.1% the next day. Thasos is at the vanguard of companies trying to help traders get ahead of stock moves like that using so-called alternative data. Such suppliers might examine mine slag heaps from outer space, analyze credit-card spending data or sort through construction permits. Thasos's specialty is spewing out of your smartphone.

Thasos gets data from about 1,000 apps, many of which need to know a phone's location to be effective, like those providing weather forecasts, driving directions or the whereabouts of the nearest ATM. Smartphone users, wittingly or not, share their location when they use such apps. Before Thasos gets the data, suppliers scrub it of personally identifiable information, Mr. Skibiski said. It is just time-stamped strings of longitude and latitude. But with more than 100 million phones providing such coordinates, Thasos says it can paint detailed pictures of the ebb and flow of people, and thus their money.

More and more Americans want to work longer -- or have to, given that many aren't saving adequately for retirement. From a report: Before our eyes, the world is undergoing a massive demographic transformation. In many countries, the population is getting old. Very old. Globally, the number of people age 60 and over is projected to double to more than 2 billion by 2050 and those 60 and over will outnumber children under the age of 5. In the United States, about 10,000 people turn 65 each day, and one in five Americans will be 65 or older by 2030. By 2035, Americans of retirement age will eclipse the number of people aged 18 and under for the first time in U.S. history.

[...] Soon, the workforce will include people from as many as five generations ranging in age from teenagers to 80-somethings. Are companies prepared? The short answer is "no." Aging will affect every aspect of business operations -- whether it's talent recruitment, the structure of compensation and benefits, the development of products and services, how innovation is unlocked, how offices and factories are designed, and even how work is structured -- but for some reason, the message just hasn't gotten through. In general, corporate leaders have yet to invest the time and resources necessary to fully grasp the unprecedented ways that aging will change the rules of the game.

What's more, those who do think about the impacts of an aging population typically see a looming crisis -- not an opportunity. They fail to appreciate the potential that older adults present as workers and consumers. The reality, however, is that increasing longevity contributes to global economic growth. Today's older adults are generally healthier and more active than those of generations past, and they are changing the nature of retirement as they continue to learn, work, and contribute. In the workplace, they provide emotional stability, complex problem-solving skills, nuanced thinking, and institutional know-how. Their talents complement those of younger workers, and their guidance and support enhance performance and intergenerational collaboration. In encore careers, volunteering, and civic and social settings, their experience and problem-solving abilities contribute to society's well-being.

Paradoxically, the abundance of tight interactions among living species usually leads to disasters in ecological models. New analyses hint at how nature seemingly defies the math. Veronique Greenwood, writing for Quantamagazine: Behind the beautiful facade of a rainforest, a savanna or a placid lake is a world teeming with contests and partnerships. Species are competing for space, consuming one another for resources, taking advantage of one another's talents, and brokering trades of nutrients. But there's something funny about this picture. When ecologists try to model ecosystems using math, they tend to find that the more interactions there are among species, the more unstable the system. For a simple ecosystem model to be stable, all the interactions among its species must be in perfect harmony. Maintaining that balancing act gets much harder, however, as the number of coupled species and the strengths of their interactions rise: Any disturbance or imbalance for one couple ripples outward and sows chaos throughout the network.

Bring in mutualisms, relationships in which species contribute directly to each other's survival, and things can really fly off the handle. Pairs of organisms that live off each other sometimes do so well in the mathematical simulations -- thriving exponentially in extreme cases, in what Robert May, the theoretical ecology pioneer, once called "an orgy of mutual benefaction" -- that everything else can go extinct. It seems unlikely that real ecosystems are quite this flimsy. In a new paper in Nature Communications, a pair of theoretical ecologists at the University of Illinois explored more precisely how the give-and-take in mutualism affects ecosystem stability and how, under the right conditions, it might contribute to it. Their result joins previous work in suggesting how real-world communities manage to be more resilient than the models imply.

Microsoft will add mouse and keyboard support to the Xbox One next week, the company announced during its X018 gaming event. From a report: In a surprising twist, Fortnite will be one of the first games to take advantage of the new feature. This update has been discussed for years, but the feature was given a concrete launch window back in September of this year, when Microsoft claimed that Warframe would be playable with a mouse and keyboard in October. The free-to-play first-person shooter will still be among the earliest games to enable this control option. Here's a roundup of everything else Microsoft announced at the gaming conference.

An anonymous reader shares a report: The ironic thing about the compressed state of air travel today is that planes are getting larger. The jet I was on, an Airbus A321, stretches nearly 23 feet longer than its predecessor, the A320. More space, more passengers, more profit. These bigger planes are increasingly the most common Âvariants -- both on American Airlines and across all carriers. The current Boeing 737s, the world's most flown craft, are all longer than the original by up to 45 feet. And yet, on the inside, we're getting squeezed.

That's because more space doesn't equal more space in Airline World. It equals more seats -- and typically less room per person. In 2017, for example, word leaked that American was planning to add six economy spots to its A320s, nine to its A321s, and 12 (that's two rows) to its Boeing 737-800s. JetBlue is reportedly ramming 12 extras into its A320s, and Delta's will gain 10. And, come 2020, you'll likely find more seats on every United plane. In Airline World, they call this densification, which is a silly word. Passengers call it arrrgh!

Consumer Reports recently polled 55,000 of its members about air travel. There were complaints about all aspects, from ticketing to agents checking carry-ons at the gate. But 30 percent of coach-class fliers rated their seats as outright uncomfortable, and every airline received extremely low scores on legroom and cushiness in economy. Clearly, things are dismal and seem to be getting even worse. They're so bad, in fact, that last year, nonprofit consumer-advocacy group FlyersRights.org filed a suit against the Federal Aviation Administration, after lobbying the agency to stop the squeeze and standardize seat sizes.

Smartphone data from riders and drivers schlepping meals for restaurant-to-home courier service Deliveroo shows that bicycles are faster than cars and motorized two-wheelers. From a news writeup, which sources its data from Deliveroo, a UK-headquartered food delivery company with more than 30,000 riders and drivers in 13 countries: That bicyclists are faster in cities will come as no surprise to bicycle advocates who have staged so-called "commuter races" for many years. However, these races -- organized to highlight the swiftness of urban cycling -- are usually staged in locations and at hours skewed towards bicycle riders. The Deliveroo stats are significant because they have been extracted from millions of actual journeys. And it's all thanks to Frank.

Frank is the name Deliveroo gives its routing algorithm (the name was chosen for the Danny DeVito character in the TV series "It's Always Sunny in Philadelphia.") Delivering millions of simultaneous orders from thousands of restaurants to hungry consumers within 30 minutes using roving self-employed couriers equipped with smartphones is a complex vehicle routing problem: consumers want piping hot food; restaurants want meals picked up when cooked; riders -- paid per drop -- want multiple deliveries per hour, and Deliveroo needs to make money. The algorithm team employs data scientists with PhDs in computer vision, computer science, operations research, cognitive neuroscience, econometrics, machine learning, and physics.

An anonymous reader writes: The Ruby programming language is impacted by a similar "deserialization issue" that has affected and wreaked havoc in the Java ecosystem in 2016; an issue that later also proved to be a problem for .NET and PHP applications as well. Researchers published proof-of-concept code this week showing how to exploit serialization/deserialization operations supported by the built-in features of the Ruby programming language itself.

"Versions 2.0 to 2.5 are affected," researchers said. "There is a lot of opportunity for future work including having the technique cover Ruby versions 1.8 and 1.9 as well as covering instances where the Ruby process is invoked with the command line argument --disable-all," the elttam team added. "Alternate Ruby implementations such as JRuby and Rubinius could also be investigated."

The deserialization issues can be used for remote code execution and taking over vulnerable servers. While .NET and PHP were affected, it was Java until now that has faced the biggest issues with deserialization, earlier this year, Oracle announcing it was dropping deserialization support from the Java language's standard package.
