Tesla’s Model Y crossover is ready for production, Elon Musk says

Posted: 24 Oct 2018 05:51 PM PDT

Tesla CEO Elon Musk said Wednesday that he recently approved the final prototype of the Model Y, signaling that the forthcoming all-electric crossover SUV is far enough along in development to go into production. Approval aside, though, he said full volume production still isn't slated to happen until 2020, which has been the target for a while now.

"We've made significant progress on the Model Y," Musk said in an uncharacteristically subdued call with investors and analysts, following news of the company's first profitable quarter in two years. The CEO has previously teased a March 2019 reveal of the SUV.

Musk didn't offer any more detail about the Model Y's development, but one reason for the delay is that Tesla doesn't have anywhere...

Don’t stress out yet about stress shrinking your brain

Posted: 24 Oct 2018 05:31 PM PDT

Relax: A new study shows that people with higher levels of the "stress hormone" tend to have smaller brains — but that doesn't mean one causes the other.

The study, published today in the journal Neurology, reports smaller brain volumes and worse memories in people with higher-than-average levels of cortisol — popularly known as the stress hormone. But any media coverage that warns stress is going to shrink your brain is premature. "Right now all we can say is A is associated with B, we can't really say anything about causality," says Sudha Seshadri, a professor of neurology at the University of Texas Health Science Center at San Antonio and senior author on the study.

"The results are fascinating," says Bruce McEwen, a neuroscientist...

Trump reportedly still uses an unsecured iPhone, and China and Russia are listening in

Posted: 24 Oct 2018 04:22 PM PDT

President Donald Trump routinely calls old friends, business partners, and confidants on his personal iPhone while in the White House, giving Chinese and Russia spies easy access to his personal communications and interests, reports The New York Times.

The story cites American intelligence reports, which detail how Trump aides have repeatedly warned the president not to use his personal iPhone and to use the secure White House landline instead. Despite the warnings, Trump continues to take personal cellphone calls, and the White House has resolved to simply hoping the president doesn't discuss classified matters over the phone.

According to the report, US intelligence agencies have reason to believe that Chinese and Russian spies are...

Amazon’s Echo and Alexa devices come to Spain and Italy

Posted: 24 Oct 2018 02:44 PM PDT

Amazon is bringing Alexa and Echo devices to Spain and Italy, months after it announced support for Spanish and Italian languages for its digital voice assistant. You can now preorder devices like the Echo, Echo Plus, Echo Dot, Echo Spot, and Echo Sub in Italy and Spain. They begin shipping next week, the company says.

It's likely Amazon wanted to wait until Alexa supported those countries' languages before selling the devices there, as it has in other international markets. In addition to language support, the Echo devices in Italy and Spain are also getting culture-specific updates to better reflect the countries they're in. For instance, by partnering with local brands, Amazon made its Echo devices capable of suggesting local news...

The first Bird Box trailer makes it look like the opposite of A Quiet Place

Posted: 24 Oct 2018 02:41 PM PDT

Back in 2014, The High Strung frontman Josh Malerman wrote his debut novel, Bird Box — a chilling post-apocalyptic movie about a young mother trying to get her two children to safety in a world overrun with monsters. The book's big hook: no one actually knows what those monsters looks like, because anyone who sees them immediately loses their mind and kills themselves, often in spectacular, horrific fashion. So the survivors protect themselves by wearing blindfolds — which limits their movement, leaves them open to all sorts of other dangers, and makes every stray sound into an unknown threat.

Bird Box is a relatively quiet, spooky novel, the kind of literary fiction that's perfect reading for a windy October night leading up to...

The Galaxy A6s is the first Samsung phone not made by Samsung

Posted: 24 Oct 2018 02:26 PM PDT

Samsung launched two new Galaxy A series phones in China today, the Galaxy A6s and the Galaxy A9s, via SamMobile. The Galaxy A9s is just a renamed Galaxy A9 for the Chinese market, so it's still the same mid-range phone with a whopping four cameras on the back. What's more interesting is the Galaxy A6s, which is Samsung's first ODM phone, or one produced by another company. According to The Korea Herald, Samsung had been in talks to outsource production of its mid- to low-end Galaxy phones to Chinese original design manufacturing company Wingtech, which produces Xiaomi phones.

The Galaxy A6s has two 12MP cameras on the back, and one 12MP front camera. The screen is a 1080p 6-inch Super AMOLED display. It's powered by a Snapdragon 660...

Major airline Cathay Pacific says up to 9.4 million passengers had their data stolen

Posted: 24 Oct 2018 01:46 PM PDT

Major international airline Cathay Pacific revealed today that as many as 9.4 million passengers had their records stolen in a data breach that occurred in March. Passport information, including identity card numbers, names, dates of birth, and postal addresses may all have been compromised.

The breach also included details about where each passenger had traveled and any comments made by customer service representatives. The amount of data accessed varied among passengers. Cathay also noted that 403 expired credit card numbers were accessed and so were 27 credit card numbers with no CVV numbers attached. We've reached out to the airline to ask if other credit cards with CVVs that haven't expired were accessed.

Tesla rides Model 3’s popularity to its first profit in two years

Posted: 24 Oct 2018 01:38 PM PDT

Tesla has posted its first profitable quarter in two years, its third ever, thanks to the popularity of the Model 3 sedan. The automaker said on Wednesday that it generated $6.8 billion in revenue in the third quarter of 2018 and walked away with $311 million in profit — the most the company has ever made in a quarter.

The company finished the quarter with $3 billion in cash, up $731 million from the second quarter of the year. Tesla's last two profitable quarters came in 2013 and 2016, and it has never made a profit over an entire year.

"Q3 2018 was a truly historic quarter for Tesla," CEO Elon Musk and CFO Deepak Ahuja wrote in a letter to investors. "Model 3 is attracting customers of both premium and non-premium brands, making it a...

An anonymous 4chan post could help solve a 25-year-old math mystery

Posted: 24 Oct 2018 01:33 PM PDT

A 4chan poster may have solved part of a very tricky math problem that mathematicians have been working on for at least 25 years. The user was just trying to figure out the most efficient way to watch episodes of a nonlinear anime series, but the result has generated considerable interest from mathematicians around the world who have no way to identify the anonymous user.

Yesterday, Robin Houston, a computer scientist and mathematician tweeted about the bizarre intersection of 4chan and mathematics, inadvertently setting off a wave of public interest in the story. Within hours of his tweet, his phone was vibrating constantly. "It started to go mad," he says. "My phone started going crazy."

The 4chan part of this saga began on...

Tim Cook wants a federal privacy law — but so do Facebook and Google

Posted: 24 Oct 2018 01:12 PM PDT

Tim Cook is done with being polite about ad-tracking. At a privacy conference in Brussels this morning, Cook gave a fiery speech denouncing the current state of data collection and targeted misinformation, drawing on aspects of Google's ad-targeting system and Facebook's social profile-building practices. For Cook, that system of data collection, collation, and targeting amounts to a "data-industrial complex," which threatens both privacy and democracy itself.

"This crisis is real," the Apple CEO said. "It is not imagined, or exaggerated, or crazy."

In what has become the most noted portion of the speech, Cook threw his support behind a new federal privacy law in the US, casting it as a necessary step in countering the growing torrents...
