Facebook Had a Terrible, Horrible, No Good, Very Bad Day

Facebook and Instagram users across the globe experienced outages for most of Wednesday starting around 1 pm EST and ending late Wednesday night. But why?

You Had a Bad Day

Facebook just had a very bad day.

Facebook, including Messenger, and Instagram users across North America experienced outages for most of Wednesday, starting in the afternoon and ending late the same night. Third party outage sites suggested it affected users across the entire globe.

The media reported it was perhaps the longest interruption ever experienced by two of the largest social networks in the world. But nobody really knows what specifically caused the outage — beyond a tweet today blaming the outage on a “server configuration change.”

“We’ve now resolved the issues and our systems are recovering,” read the tweet. “We’re very sorry for the inconvenience and appreciate everyone’s patience.”

Yesterday, as a result of a server configuration change, many people had trouble accessing our apps and services. We've now resolved the issues and our systems are recovering. We’re very sorry for the inconvenience and appreciate everyone’s patience.

— Facebook (@facebook) March 14, 2019

“Server Configuration Change”

Theories swirled on Twitter about what could have caused the massive outage on Facebook, which didn’t respond to questions from Futurism.  Facebook quickly ruled out one of the most popular theories via a tweet: it wasn’t a denial-of-service attack (DDoS) — an attack that involves countless infected computers being leveraged to attack a single target system.

It was an outage that didn’t just enrage individual users: Facebook likely felt the pressure from countless ad partners and businesses that relied on the network.

Founder and CEO of free encrypted messaging app Telegram announced that the service signed up three million new users on the day of Facebook’s outage.

Break ‘Em Up

The outage came days after senator and presidential candidate Elizabeth Warren announced a bold plan Friday to break up tech giants Amazon, Facebook, and Google.

“Unwinding these mergers will promote healthy competition in the market — which will put pressure on big tech companies to be more responsive to user concerns, including about privacy,” Warren wrote in a Medium post.

To make Facebook’s terrible day even worse, the company was hit with a criminal investigation by New York prosecutors about data deals Facebook struck with other tech companies like Amazon, Apple, Microsoft, and Sony.

A grand jury in New York requested records from two device makers who had active partnerships with Facebook, the New York Times reported yesterday. The exact focus of the investigation isn’t yet clear.

See the Most Breathtaking Views of the Martian Surface Yet

Mars in Stereo

The European Space Agency’s (ESA) ExoMars Trace Gas Orbiter, which launched in 2016, just sent back some spectacular images of the Martian surface.

The orbiter is equipped to take images of the Martian surface in glorious 3D. The picture below shows the Columbus Crater on Mars’ southern hemisphere — which NASA discovered that sulfate particles contain hydrated minerals.

Peekaboo, InSight

Another amazing shot: a pic of NASA’s InSight lander hammering away at the Martian surface earlier this month. It’s the first time a European orbiter has taken a picture of InSight — though NASA’s own Mars Reconnaissance Orbiter spotted InSight from orbit in December.

InSight’s heat shield, landing parachutes protective shell can also be seen as small dots.

Martian Dust Devils

A stereoscopic image shows dust devil streaks, in blue, on the edge of a massive crater. Throw on a pair of basic 3D glasses to appreciate the full effect.

The following images shows the edge of the Burroughs crater roughly 120 miles northwest of Mars’ northern polar ice cap. Some of the northernmost mounds are thought to be completely made up of “nearly pure water ice.”

This Autonomous Robot Arm Feeds People Who Can’t Feed Themselves

Mealtime Tech

An estimated one million Americans can’t feed themselves. That leaves them little choice but to rely on another person at mealtime, which can be both awkward and time-consuming.

But now, researchers from the University of Washington have built Assistive Dexterous Arm (ADA), an artificially intelligent robot arm capable of using a fork to move food from a person’s plate to their mouth — another encouraging example of how AI and robotics can help people with disabilities live more independent lives.

Food for Bot

In a pair of recently published papers, the UW team describes how a pair of algorithms give ADA the ability to feed a person.

The first algorithm, RetinaNet, is an object-detection system. It scans a plate to determine the types of food on it, placing a “frame” around each item.

The second algorithm, SPNet, analyzes the food in a frame and sends instructions to the robot arm that let it know how to skewer the food in a way that’ll be easy for a person to eat — it might instruct the bot to stab a piece of banana in its center, for example, but a carrot near one end.

Giving the system the contextual knowledge that not all food should be treated the same way was a key part of ADA’s development process, according to researcher Siddhartha Srinivasa.

“If we don’t take into account how easy it is for a person to take a bite, then people might not be able to use our system,” he said in a press release. “There’s a universe of types of food out there, so our biggest challenge is to develop strategies that can deal with all of them.”

Team Effort

Once the robotic arm, which attaches to a wheelchair, receives its instructions from the algorithm, it relies on a system of sensors and cameras to skewer each piece of food with a 3D-printed fork and move it to a person’s mouth so they can eat it.

While Srinivasa is hopeful that ADA will provide people who have trouble feeding themselves with a new level of independence, he doesn’t see envision the system eliminating the need for human help altogether.

“Ultimately our goal is for our robot to help people have their lunch or dinner on their own,” he said in the press release. “But the point is not to replace caregivers: We want to empower them. With a robot to help, the caregiver can set up the plate, and then do something else while the person eats.”

DARPA Is Building an Open Source Voting Machine

DARPA is developing technology that could finally lead to secure voting machines. It plans to have experts from professors to hackers kick the tires.

Cracking Down

Voting booths are notoriously buggy. Whether they’ve been actively hacked or just improperly calibrated, every election season is rife with complaints that machines misrecorded ballots or that an election has been compromised by hackers.

To prevent us from having to take a technological step backwards to paper ballots, U.S. Department of Defense’s research division DARPA is working with cybersecurity firm Galois to develop open source voting machine technology that would let people verify that their votes were tallied correctly, according to Motherboard.

Open Source

The ultimate goal isn’t to sell machines, but to develop tech that would beef up existing voting machine vendors’ security.

“We will not have a voting system that we can deploy. That’s not what we do,” Linton Salmon, the DARPA scientist managing the project, told Motherboard. “We will show a methodology that could be used by others to build a voting system that is completely secure.”

Kicking The Tires

To make sure that any new voting machines built with DARPA software are actually better than today’s, the plan is to invite experts ranging from academic computer scientists to hackers to test it out and search for vulnerabilities, according to Motherboard.

One way that the new system might improve upon others is by printing out a sheet showing a voter’s selections so that they can look it over before feeding it into a separate machine that will actually record the vote.

“That receipt does not permit you to prove anything about how you voted, but does permit you to prove that the system accurately captured your intent and your vote is in the final tally,” Galois principal scientist Joe Kiniry told Motherboard.

Scientists Create Material That Blocks Sound, but Not Air or Light

A new

Listen Up

By combining math with 3D printing, researchers from Boston University have created a new material that seemingly defies logic: light and air have no trouble passing through it — but sound cannot.

“The idea is that we can now mathematically design an object that can block the sounds of anything,” researcher Xin Zhang said in a press release — meaning the future could be far quieter than the present.

Silent Treatment

In a paper published in the journal Physical Review B , the researchers describe the work that went into creating what they call their “acoustic metamaterial.”

They started by calculating the dimensions and specification a material would need to have to be able to reflect incoming sound waves back to their source without blocking air or light. Then they 3D printed the material into a donut shape and attached it to one end of a PVC pipe, the other end of which they attached to a loudspeaker.

When they blasted a high-pitched note from the loudspeaker, they found that the shape blocked 94 percent of the sound coming through the pipe.

“The moment we first placed and removed the silencer…was literally night and day,” researcher Jacob Nikolajczyk said in the press release. “We had been seeing these sorts of results in our computer modeling for months — but it is one thing to see modeled sound pressure levels on a computer, and another to hear its impact yourself.”

A Quiet Place

The researchers envision many applications for their acoustic metamaterial, which they claim isn’t limited to the donut shape demonstrated by their research.

“Our structure is super lightweight, open, and beautiful,” Zhang and her fellow researcher Reza Ghaffarivardavagh said in the press release. “Each piece could be used as a tile or brick to scale up and build a sound-canceling, permeable wall.”

They also note the potential to use the material to dampen the sound of drones, HVAC systems, or even MRI machines — seemingly anything that makes noise could make less noise with the addition of this new material.

Mind Bomb – Wikipedia

1989 studio album by The The

Mind Bomb is the third studio album by English post-punk band The The, released by Some Bizzare/Epic on 11 July 1989 and recorded between October 1988 and May 1989.

For this album, instead of recording with numerous session musicians as he did previously, Matt Johnson assembled a genuine band behind him to play the bulk of the instrumentation (additional flourishes were nevertheless provided by sessioneers, most notably keyboard player Wix). Instead of the darkly polished dance-pop styling of earlier albums Soul Mining and Infected, Mind Bomb opens up the music to reveal a slow, winding textured world of sound, thanks in no small means to ex-Smiths guitarist Johnny Marr. Lyrical subjects include politics, religion, and romance. The band would also play a world tour and record a follow-up, Dusk. After that, Johnson dissolved it and went about his business alone again. A remastered version of the album was released in 2002.

Tracks written by Matt Johnson, except where noted.

Ripple Price Forecast: XRP vs SWIFT, SEC Updates, and More

Ripple vs SWIFT: The War Begins
While most criticisms of XRP do nothing to curb my bullish Ripple price forecast, there is one obstacle that nags at my conscience. Its name is SWIFT.

The Society for Worldwide Interbank Financial Telecommunication (SWIFT) is the king of international payments.

It coordinates wire transfers across 11,000 banks in more than 200 countries and territories, meaning that in order for XRP prices to ascend to $10.00, Ripple needs to launch a successful coup. That is, and always has been, an unwritten part of Ripple’s story.

We’ve seen a lot of progress on that score. In the last three years, Ripple wooed more than 100 financial firms onto its.

Cryptocurrency Price Forecast: Trust Is Growing, But Prices Are Falling

Trust Is Growing…
Before we get to this week’s cryptocurrency news, analysis, and our cryptocurrency price forecast, I want to share an experience from this past week. I was at home watching the NBA playoffs, trying to ignore the commercials, when a strange advertisement caught my eye.

It followed a tomato from its birth on the vine to its end on the dinner table (where it was served as a bolognese sauce), and a diamond from its dusty beginnings to when it sparkled atop an engagement ring.

The voiceover said: “This is a shipment passed 200 times, transparently tracked from port to port. This is the IBM blockchain.”

Let that sink in—IBM.

Cryptocurrency News: Bitcoin ETFs, Andreessen Horowitz, and Contradictions in Crypto

Cryptocurrency News
This was a bloody week for cryptocurrencies. Everything was covered in red, from Ethereum (ETH) on down to the Basic Attention Token (BAT).

Some investors claim it was inevitable. Others say that price manipulation is to blame.

We think the answers are more complicated than either side has to offer, because our research reveals deep contradictions between the price of cryptos and the underlying development of blockchain projects.

For instance, a leading venture capital (VC) firm launched a $300.0-million crypto investment fund, yet liquidity continues to dry up in crypto markets.

Another example is the U.S. Securities and Exchange Commission’s.

Cryptocurrency News: Looking Past the Bithumb Crypto Hack

Another Crypto Hack Derails Recovery
Since our last report, hackers broke into yet another cryptocurrency exchange. This time the target was Bithumb, a Korean exchange known for high-flying prices and ultra-active traders.

While the hackers made off with approximately $31.5 million in funds, the exchange is working with relevant authorities to return the stolen tokens to their respective owners. In the event that some is still missing, the exchange will cover the losses. (Source: “Bithumb Working With Other Crypto Exchanges to Recover Hacked Funds,”.

Cryptocurrency News
On the whole, cryptocurrency prices are down from our previous report on cryptos, with the market slipping on news of an exchange being hacked and a report about Bitcoin manipulation.

However, there have been two bright spots: 1) an official from the U.S. Securities and Exchange Commission (SEC) said that Ethereum is not a security, and 2) Coinbase is expanding its selection of tokens.

Let’s start with the good news.
SEC Says ETH Is Not a Security
Investors have some reason to cheer this week. A high-ranking SEC official told attendees of the Yahoo! All Markets Summit: Crypto that Ethereum and Bitcoin are not.

Cryptocurrency News: What You Need to Know This Week

Cryptocurrency News
Cryptocurrencies traded sideways since our last report on cryptos. However, I noticed something interesting when playing around with Yahoo! Finance’s cryptocurrency screener: There are profitable pockets in this market.

Incidentally, Yahoo’s screener is far superior to the one on CoinMarketCap, so if you’re looking to compare digital assets, I highly recommend it.

But let’s get back to my epiphany.

In the last month, at one point or another, most crypto assets on our favorites list saw double-digit increases. It’s true that each upswing was followed by a hard crash, but investors who rode the trend would have made a.

Cryptocurrency News: XRP Validators, Malta, and Practical Tokens

Cryptocurrency News & Market Summary
Investors finally saw some light at the end of the tunnel last week, with cryptos soaring across the board. No one quite knows what kicked off the rally—as it could have been any of the stories we discuss below—but the net result was positive.

Of course, prices won’t stay on this rocket ride forever. I expect to see a resurgence of volatility in short order, because the market is moving as a single unit. Everything is rising in tandem.

This tells me that investors are simply “buying the dip” rather than identifying which cryptos have enough real-world value to outlive the crash.

So if you want to know when.

Cryptocurrency News: New Exchanges Could Boost Crypto Liquidity

Cryptocurrency News
Even though the cryptocurrency news was upbeat in recent days, the market tumbled after the U.S. Securities and Exchange Commission (SEC) rejected calls for a Bitcoin (BTC) exchange-traded fund (ETF).

That news came as a blow to investors, many of whom believe the ETF would open the cryptocurrency industry up to pension funds and other institutional investors. This would create a massive tailwind for cryptos, they say.

So it only follows that a rejection of the Bitcoin ETF should send cryptos tumbling, correct? Well, maybe you can follow that logic. To me, it seems like a dramatic overreaction.

I understand that legitimizing cryptos is important. But.

Although cryptocurrency prices were heating up last week (Bitcoin, especially), regulators poured cold water on the rally by rejecting calls for a Bitcoin exchange-traded fund (ETF). This is the second time that the proposal fell on deaf ears. (More on that below.)

Crypto mining ran into similar trouble, as you can see from Advanced Micro Devices, Inc.‘s (NASDAQ:AMD) most recent quarterly earnings. However, it wasn’t all bad news. Investors should, for instance, be cheering the fact that hedge funds are ramping up their involvement in cryptocurrency markets.

Cryptocurrency News: Vitalik Buterin Doesn’t Care About Bitcoin ETFs

Cryptocurrency News
While headline numbers look devastating this week, investors might take some solace in knowing that cryptocurrencies found their bottom at roughly $189.8 billion in market cap—that was the low point. Since then, investors put more than $20.0 billion back into the market.

During the rout, Ethereum broke below $300.00 and XRP fell below $0.30, marking yearly lows for both tokens. The same was true down the list of the top 100 biggest cryptos.

Altcoins took the brunt of the hit. BTC Dominance, which reveals how tightly investment is concentrated in Bitcoin, rose from 42.62% to 53.27% in just one month, showing that investors either fled altcoins at higher.

Self-Powered Sensor Helps Track Firefighters in Burning Buildings

A sensor the size of a watch battery could help track firefighters and those in dangerous working conditions.

Heated Situation

No bigger than an ordinary watch battery, adding this little sensor to firefighter’s gear could help save lives.

Researchers from McMaster University in Hamilton, Ontario announced on Friday they had created a fireproof, self-powered sensor that could be used to track people working in high-risk environments, such as firefighters, steelworkers, and miners. The research team – from McMaster, UCLA, and University of Chemistry and Technology Prague – published their work in the journal Nano Energy.

Cool Gadget

The self-powered sensor is embedded in the sole of a boot or under the arm of a jacket, areas where frequent motion can be registered by the device. The friction of motion generated in these areas charges the sensor, similar to the static charge you sometimes generate by sliding your socks on the carpet. If motion stops, the device alerts someone outside the hazardous area so help can be sent.

“If somebody is unconscious and you are unable to find them, this could be very useful,” said Ravi Selvaganapathy, a professor of mechanical engineering who oversaw the project. “The nice thing is that because it is self-powered, you don’t have to do anything. It scavenges power from the environment.”

High heat environments have posed a challenge to similar sensors. The new sensor is self-charging, since most batteries breakdown in hot environments, and thanks to its key material, a new carbon aerogel nanocomposite, it successfully withstood temperatures up to 300° Celsius (572° Fahrenheit), around the temperature most wood starts to burn.

Stayin’ Alive

The research team is hoping to connect with a commercial partner to help make the device more accessible to a larger market. Such a device could make a world of difference to those working in hostile environments and particularly to local fire departments.

“It’s exciting to develop something that could save someone’s life in the future,” said co-author Islam Hassan, a McMaster PhD student in mechanical engineering. “If firefighters use our technology and we can save someone’s life, that would be great.”
