That's enough angry Facebooking for you:

Late on Thursday, Facebook announced a plan to emphasize more "meaningful" interactions on the platform. Posts are considered meaningful when they generate lots of comments, likes, and shares. Facebook's researchers have found that when people are actively commenting on posts, they tend to feel better about using social networks — and feel better about themselves in general.

The change may sound relatively small, but it's likely to have significant consequences for the broad subset of Facebook users that aren't individual people: media companies, small businesses, big brands, and everyone else who has come to see Facebook's News Feed as an essential way to reach audiences and customers. In a post yesterday, CEO Mark Zuckerberg said the pages managed by those businesses are likely to reach far fewer people in 2018.

"As we roll this out, you'll see less public content like posts from businesses, brands, and media," he wrote. "And the public content you see more will be held to the same standard -- it should encourage meaningful interactions between people."

He added: "Now, I want to be clear: by making these changes, I expect the time people spend on Facebook and some measures of engagement will go down. But I also expect the time you do spend on Facebook will be more valuable. And if we do the right thing, I believe that will be good for our community and our business over the long term too."

Sixty games were booted off the Play Store after security firm Check Point discovered that they contained pornographic ads and malicious components. Before their removal, the games were downloaded between 3 million and 7 million times, according to the download metrics on the Play Store.

The malware is dubbed "AdultSwine," and according to Check Point Research, it had three main features:

1. Displaying ads from the Web that are often highly inappropriate and pornographic
2. Attempting to trick users into installing fake "security apps"
3. Inducing users to register to premium services at the user's expense

The 60 listings in the Play Store were generally knockoff games, like "Five Nights Survival Craft." In some cases, the creator simply stole a real IP, as in "Drawing Lessons Angry Birds." Once installed, the app would phone home, sending information about the user's phone and receiving instructions on how to operate. The app could hide its icon, making removal more difficult. Check Point says the malware could display ads from "the main ad providers" or switch to its own ad server, which provided porn ads, scareware ads, and ads that tricked the user into signing up for premium services. AdultSwine not only displayed ads while users played the game that came with the malware; it could also show pop-up ads on top of other apps.

What caught my eye initially was the unusual track of the flight path.

A United Launch Alliance Delta 4 rocket climbed into orbit Friday from Vandenberg Air Force Base in California with a top secret spy satellite, adding a new set of eyes in the sky for the U.S. government's intelligence community and nudging part of the Delta 4 family closer to retirement.

The 217-foot-tall (66-meter) Delta 4 rocket lifted off at 2:11 p.m. PST (5:11 p.m. EST; 2211 GMT) from Space Launch Complex 6 at Vandenberg on the power of an Aerojet Rocketdyne RS-68A main engine and two Orbital ATK-built solid rocket boosters.

[...] ULA confirmed the flight's successful outcome in a press release around two hours after liftoff.

[...] "It's a classified payload for the NRO," Varghese said in a pre-launch interview. "We can't go into the details of what the payload does, but it's a national security priority, and it's mission will ensure that the warfighters across the globe have the appropriate intel that they need to be able to support operations."

Codenamed NROL-47, the satellite lofted Friday will likely join the NRO's fleet of orbiting radar reconnaissance stations.

The Delta 4's trajectory toward the southwest suggested it was bound for an unusual high-inclination retrograde orbit that would allow the rocket's top secret payload to travel in the opposite direction of Earth's rotation.

Psychologists claim that taking three or more selfies a day could be a sign of mental illness.

In 2014, a spoof news article coined the term "selfitis," saying that the American Psychiatric Association was going to start recognising it as a real disorder.

Three years on, two researchers have looked at the term and have decided there could be some truth to it.

Psychologists Mark D. Griffiths and Janarthanan Balakrishnan have published a paper in the International Journal of Mental Health and Addiction, in which they argue that selfitis is a real condition, and can be diagnosed as excessive selfie taking.

They also developed a "Selfitis Behaviour Scale" by surveying the selfie behaviour of 400 participants from India. The scale assesses the severity of the condition, of which there are three levels.

India was chosen for the study as the country has the most selfie-related deaths. Out of 127 selfie-related deaths that have been reported worldwide between March 2014 and September 2016, 76 occurred in India.

You may not think much about the switches that sit underneath the keycaps of your keyboard, but there's a large contingent of enthusiasts who really, really care. And for those users, Cherry's various MX-branded switches are somewhat of a standard. Because they include a number of mechanical parts, though, you won't see a lot of laptop-like thin mechanical keyboards or mechanical keyboards on more than a handful of laptops.

The trend, however, is clearly going toward slim keyboards — and that's not lost on Cherry. So at CES this week, the company is introducing a completely new line of keyboard switches that may just be small enough to bring mechanical keyboards to more laptops (or at least more niche gaming laptops) and thinner keyboards. These new switches are low-profile versions of the Cherry MX RGB switch, a switch that features colored LEDs and which is especially popular with gamers. The company tells me that, if successful, it'll launch thinner versions of its other MX switches, too.

The explosive growth in the NAND flash market may be slowing down:

After a blistering year-and-a-half long surge, a sudden drop in some memory prices, followed by Samsung Electronics Co's disappointing profit estimate, is causing jitters among investors who had bet the chip boom would last at least another year.

Amid news that the market has started losing some steam - prices of high-end flash memory chips, which are widely used in smartphones, dropped nearly 5 percent in the fourth quarter - some analysts now expect the industry's growth rate will fall by more than half this year to 30 percent.

That led shares in Samsung to dip 7.5 percent last week, while its home rival SK Hynix fell 6.2 percent. But analysts say that there is unlikely to be a sudden crash, and that 2018 should be a relatively stable year for chipmakers.

The $122 billion memory chip industry has enjoyed an unprecedented boom since mid-2016, expanding nearly 70 percent in 2017 alone thanks to robust growth of smartphones and cloud services that require more powerful chips that can store more data.

CubeSats carrying amateur radio payloads were among the 31 satellites successfully launched on January 12 at 0359 UT on the ISRO PSLV-C40 mission from Satish Dhawan Space Centre in Sriharikota, India.

Two of the CubeSats, Fox-1D and PicSat, carry amateur radio FM transponders, but neither is yet available for general amateur use. The PicSat FM transponder is unusual in that instead of a CTCSS tone it requires a 1750 Hz tone burst to activate. The 1750 Hz tone burst used to be popular on IARU Region 1 FM repeaters in the 1980s and 90s before the widespread use of CTCSS.

CNUSail-1, built by students at the Chungnam National University in Korea, carries a deployable sail. The students have requested the help of radio amateurs in receiving the 437.100 MHz 9600 bps BPSK beacon, further information is available at https://sites.google.com/view/cnuusg

One site lists these frequencies for the satellites carrying amateur radio payloads, while JE9PEL has these frequencies for the latest launches.

Everyone Is Getting Hilariously Rich and You're Not

Recently the founder of something called Ripple briefly became richer than Mark Zuckerberg. Another day an anonymous donor set up an $86 million Bitcoin-fortune charity called the Pineapple Fund. A Tesla was spotted with a BLOCKHN license plate. There's a surge in people looking to buy Bitcoin on their credit cards. After the Long Island Iced Tea company announced it would pivot to blockchain, its stock rose 500 percent in a day.

In 2017, the cryptocurrency Bitcoin went from $830 to $19,300, and now quivers around $14,000. Ether, its main rival, started the year at less than $10, closing out 2017 at $715. Now it's over $1,100. The wealth is intoxicating news, feverish because it seems so random. Investors trying to grok the landscape compare it to the dot-com bubble of the late 1990s, when valuations soared and it was hard to separate the Amazons and Googles from the Pets.coms and eToys.

The cryptocurrency community is centered around a tightknit group of friends — developers, libertarians, Redditors and cypherpunks — who have known each other for years through meet-ups, an endless circuit of crypto conferences and internet message boards. Over long hours in anonymous group chats, San Francisco bars and Settlers of Catan game nights, they talk about how cryptocurrency will decentralize power and wealth, changing the world order. The goal may be decentralization, but the money is extremely concentrated. Coinbase has more than 13 million accounts that own cryptocurrencies. Data suggests that about 94 percent of the Bitcoin wealth is held by men [archive], and some estimate that 95 percent of the wealth is held by 4 percent of the owners.

There are only a few winners here, and, unless they lose it all, their impact going forward will be outsize.

They also remember who laughed at them and when.

It's a fart-measuring pill:

Scientists often hope to break ground with their research. But a group of Australian researchers would likely be happy with breaking wind.

The team developed an ingestible electronic capsule [open, DOI: 10.1038/s41928-017-0004-x] to monitor gas levels in the human gut. When it's paired with a pocket-sized receiver and a mobile phone app, the pill reports tail-wind conditions in real time as it passes from the stomach to the colon. The researchers, led by Kourosh Kalantar-Zadeh of RMIT University and Peter Gibson of Monash University, reported their invention Monday in Nature Electronics.

Jeff Bezos is coming out of his shell, and it only took $100+ billion to get started:

As he was shaping Amazon into one of the world's most valuable companies, Mr. Bezos developed a reputation as a brilliant but mysterious and coldblooded corporate titan. He preferred to hunker down in Amazon's hometown, Seattle, at least partly because he thought it was better for Amazon's growing business, largely avoiding public causes and the black-tie circuit. But while Mr. Bezos — who at 53 is the world's richest person, with a net worth of more than $100 billion — can afford virtually any luxury, obscurity is no longer among them.

Amazon, now a behemoth valued at more than $600 billion, has become one of the faces of "big tech," along with Apple, Alphabet's Google and Facebook. These companies are facing a backlash. Amazon is under the microscope for what critics say is its corrosive effect on jobs and competition, and Mr. Bezos has become a bête noire for President Trump, who repeatedly singles out him and Amazon for scorn on Twitter. "People are starting to get scared of Amazon," said Steve Case, a co-founder of America Online, who recently started an investment fund focused on start-ups in underserved areas, with Mr. Bezos among its contributors. "If Jeff continues to hang out in Seattle, he's going to get a lot more incoming. Even for just defense reasons, he has to now play offense."

Mr. Bezos' portfolio of other ventures has thrust him farther into the spotlight. Four years ago, he bought The Washington Post for $250 million, jump-starting a renaissance of the paper. In 2016, Mr. Bezos bought a $23 million home in Washington, one of the city's most expensive, which is undergoing extensive renovations to make it a suitable party spot for the city's political class. Nearby neighbors include former President Barack Obama and his family, and Mr. Trump's daughter Ivanka Trump and her husband, Jared Kushner.

Mr. Bezos' space start-up, Blue Origin, is also making its efforts more public, giving him another stage. The company is trying to rescue Earth by helping to move pollution-belching heavy industries off the planet.

The Guardian is reporting Cranberries singer Dolores O'Riordan dies aged 46:

Death of Irish singer, whose band sold more than 40m records, is being treated as ‘unexplained’

[...] The news was confirmed by her publicist in a statement, but no cause of death has yet been announced. O’Riordan, who had to cancel a tour with a reunited Cranberries in 2017 because of a back problem, had been in London for a recording session.

The statement described the death as sudden, and added: “Family members are devastated to hear the breaking news and have requested privacy at this very difficult time.”

A Metropolitan police statement also confirmed the news, and that O’Riordan’s body was found at a Park Lane hotel. “At this early stage the death is being treated as unexplained,” the statement read.

A spokeswoman for the London Hilton on Park Lane said: “It is with deep regret that we can confirm a guest sadly passed away at the hotel on Monday 15 January. We offer our sincere condolences to their family at this difficult time.”

Irish president Michael D Higgins said he learned of the news with “great sadness”, adding: “To all those who follow and support Irish music, Irish musicians and the performing arts, her death will be a big loss.”

Musicians have started to pay tribute, including Irish songwriter Hozier, who said he was “shocked and saddened”, and that O’Riordan’s voice “threw into question what a voice could sound like in that context of rock. I’d never heard somebody use their instrument in that way.”

The Guardian also has a story up The Cranberries: five of Dolores O’Riordan's best performances which has background stories on — and links to — five of her performances.

Also covered by the BBC.

Though I was not a huge fan, I most certainly recognized a unique and unmistakable voice that carried passion and power. RIP.

Google temporarily bans addiction center ads globally following exposure of seedy referral deals

Google is temporarily halting advertisements worldwide for addiction and rehabilitation centers, following a report last week showing it was acting as a platform for shady referral services earning huge undisclosed commissions.

Essentially these ads, which commanded huge prices on Google's networks, would show for people seeking addiction treatment; the help lines and services listed would then refer the person to an addiction center. These centers were, unknown to their new patients, paying enormous finders fees to the referral services, on the order of tens of thousands of dollars.

The ads were already banned in the U.S., but were banned in the UK following a Sunday Times investigation. Google then extended that ban worldwide.

Physicists Say They've Created a Device That Generates 'Negative Mass'

Physicists have created what they say is the first device that's capable of generating particles that behave as if they have negative mass. The device generates a strange particle that's half-light/half-matter, and as if that isn't cool enough, it could also be the foundation for a new kind of laser that could operate on far less energy than current technologies.

This builds on recent theoretical work on the behaviour of something called a polariton, which appears to behave as if it has negative mass – a mind-blowing property that sees objects move towards the force pushing it, instead of being pushed away.

Now physicists from the University of Rochester have created a device that allows them to actually create these polaritons at room temperature. They do this by manipulating captured photons and combine them with a kind of quasi-particle called an exciton to make something half-light/half-matter that some scientists affectionately refer to as 'magic dust'.

This alone is "interesting and exciting from a physics perspective," says quantum physicist Nick Vamivakas from Rochester's Institute of Optics. "But it also turns out the device we've created presents a way to generate laser light with an incrementally small amount of power."

Virgin Galactic conducted its first test flight of its SpaceShipTwo suborbital vehicle in more than five months Jan. 11 as the company prepares to begin powered test flights of the vehicle.

The glide flight, conducted in the skies above the Mojave Air and Space Port in California, was the seventh for the second SpaceShipTwo, named VSS Unity, dating back to December 2016. Pilots Mark Stucky and Michael Masucci landed the vehicle at the airport after a successful flight.

The glide flight was the first for SpaceShipTwo since one in early August. The company said in a statement that it had spent the intervening months on "extensive analysis, testing and small modifications to ensure vehicle readiness for the higher loads and forces of powered test flight."

Virgin Galactic tested those modifications on the glide flight, as the pilots pushed the vehicle into a steep descent shortly after release from its WhiteKnightTwo carrier aircraft, reaching a top speed of Mach 0.9. That is the fastest the vehicle can fly without igniting its hybrid rocket motor, according to the company.

This flight may be the last glide test before the vehicle begins powered test flights. "I think we'll probably do one more glide flight, and then we'll be ready to go into powered flight," George Whitesides, chief executive of Virgin Galactic, said in a presentation at the Next-Generation Suborbital Researchers Conference in Broomfield, Colorado, Dec. 18.

[...] Virgin Galactic's first SpaceShipTwo, VSS Enterprise, was lost in an accident in a powered test flight in October 2014, the fourth for that vehicle. An investigation by the National Transportation Safety Board concluded the vehicle's co-pilot prematurely unlocked the feathering system for the vehicle that raises its tail for reentry, causing the vehicle to become aerodynamically unstable and break up as it passed through Mach 1. The investigation also blamed vehicle designers for not including safety systems that would have prevented the feathering system from being unlocked during that phase of flight.
