Amazon launches its first inexpensive Fire TV televisions with Dolby Vision support

Posted: 20 Jun 2019 03:27 PM PDT

Amazon and its manufacturer partners have been selling inexpensive 4K TVs with Fire TV software built in for a few years now. But tonight, Amazon announced the first model that includes support for Dolby Vision. The Toshiba-branded set will be sold exclusively by Amazon and Best Buy. A 55-inch model ($449.99) is on sale immediately today, and 43-inch ($329.99) and 50-inch ($379.99) models will be available later this month on June 30th.

Dolby Vision is an HDR format that offers a wider color palette and brighter highlights than TVs that lack HDR. It's also seen as superior to HDR10 since adjustments to picture quality can be made scene by scene, whereas HDR10 applies one set of parameters to an entire show or movie. Dolby Vision and...

Netflix’s latest Hack Day projects include rumble packs for smartphone viewers

Posted: 20 Jun 2019 03:14 PM PDT

A couple of times a year, Netflix hosts an internal hackathon for its employees, where they can take time off of their regular duties and try their hand at playing with new ideas. At this spring's Hack Day, Netflix employees devised a haptic feedback system for mobile devices, and a novel way to get their colleagues out of a meeting room when their time runs over.

In past years, Netflix employees have used the Hack Day event on zany ideas like playing House of Cards on an original NES, turning their catalog into a VR rental store, creating a search system that uses Morse code, and adding a "jump to shark" button to Sharknado, among other things. The ideas don't generally have practical purposes — the purpose of the day is the creative...

Everything you need to know about Libra, Facebook’s ambitious cryptocurrency

Posted: 20 Jun 2019 02:35 PM PDT

Facebook is planning to launch a cryptocurrency it hopes will "transform the global economy." The currency, named Libra, is being developed by Facebook, but the company intends to share control with a consortium of organizations, including venture capital firms, credit card companies, and other tech giants.

At launch, you'll be able to send Libra inside of Facebook Messenger and WhatsApp, with it mostly being meant as an intermediary for transferring traditional currencies. Eventually, Facebook hopes Libra will be accepted as a form of payment, and other financial services will be built on top of its blockchain-based network.

Facebook is also launching a subsidiary company, Calibra, which will develop products and services based around...

YouTuber proves Apple’s new Mac Pro would not actually grate cheese that great

Posted: 20 Jun 2019 12:53 PM PDT

Ever since Apple first announced its new, cheese grater-shaped take on the Mac Pro, one question has been on everyone's mind: how well would the Mac Pro actually work as a $6,000-plus cheese grater? Fortunately, we no longer have to wait, thanks to YouTube Winston Moy, who went and machined a replica of Apple's new Mac Pro chassis to answer the question once and for all.

Unsurprisingly, it doesn't do a great job, which sort of makes sense given the Mac Pro is not even remotely designed to grate cheese. It's designed to vent air from the inside of the Mac Pro, not turn hard cheeses into shredded bits to garnish a bowl of pasta.

But what Moy's video does highlight is the level of detail and difficulty that Apple is...

Google says it’s done making tablets and cancels two unreleased products

Posted: 20 Jun 2019 12:29 PM PDT

Google will not be launching a sequel to last year's Pixel Slate tablet, according to Business Insider and Computer World, and will instead focus its Chrome OS hardware efforts on traditional laptop devices like the Pixelbook. "For Google's first-party hardware efforts, we'll be focusing on Chrome OS laptops and will continue to support Pixel Slate," a spokesperson told Business Insider.

Translation: you can expect the Slate to continue to receive software and security updates for several years to come — but there won't be a Pixel Slate 2. Rick Osterloh, who leads Google's hardware business, confirmed as much on Twitter on Thursday afternoon.

Walmart is using AI-powered cameras to prevent theft at checkout lanes

Posted: 20 Jun 2019 12:12 PM PDT

Walmart has been surveilling its checkout registers using a computer vision technology called Missed Scan Detection to identify when items move past the scanner without having been scanned. As reported by Business Insider, the technology has been implemented in more than 1,000 stores across the US over the past two years, and it monitors both self-checkout kiosks and traditional registers managed by human cashiers.

The system runs on cameras that watch as items move across the register. If an unusual activity occurs, such as an item moving into a bag without being scanned, a checkout attendant will be notified to take action. Missed Scan Detection was designed to help reduce theft and other losses, a problem that has cost US retailers up...

Good Omens protesters demand show be removed from completely wrong company

Posted: 20 Jun 2019 12:06 PM PDT

It's a truth universally acknowledged, that an angry fan online must be in search of a website to launch a mostly useless petition. A recent protest from a Christian group asking Netflix to remove Good Omens from its library is a perfect example — except that Good Omens isn't part of Netflix's library, because it's an Amazon show.

The petition was first reported by The Guardian, which discovered that a Christian organization known as the Return to Order campaign launched the petition on its website asking Netflix to remove the series, which is an adaptation of Neil Gaiman and Terry Pratchett's beloved satirical novel from 1990 about the apocalypse. The petition argued the show was another flagrant attempt to "make satanism appear...

Apple says incoming China tariffs would be disastrous for business

Posted: 20 Jun 2019 11:35 AM PDT

Apple says the Trump administration's tariffs could lower the company's economic output and put it at a disadvantage compared to its international competitors, particularly its Chinese counterparts. In Apple's letter to US Trade Representative Robert Lighthizer, the company argues that the proposed tariffs, which would impact nearly every Apple device including the iPhone, MacBook, AirPods, and Apple Watch, would hurt Apple's US employees and its ability to contribute to the US economy.

Up until now, Apple has more or less skirted around the Trump administration's tariffs, despite its heavy reliance on Chinese manufacturing. Earlier rounds of China tariffs had avoided Apple's highest volume devices, like the iPhone and Apple Watch, but...

Google Maps has a fake business listing problem

Posted: 20 Jun 2019 11:28 AM PDT

Google Maps is overrun with fake business listings and phone numbers that reroute to competing businesses, according to a Wall Street Journal report. Hundreds of thousands of fake listings appear on Google Maps every month, with the Journal estimating the service currently has about 11 million falsely listed businesses.

Though Google claims in a self-funded 2017 academic study that only 0.5 percent of local searches are false listings, a separate investigation by the Journal suggested otherwise. In searching for plumbers in New York City, the Journal found 13 of the top 20 Google search results listed false addresses, and only two were real businesses that actually adhered to Google guidelines, which stipulate that pushpin listings must...

Facebook’s Libra won’t be as power-hungry as Bitcoin

Posted: 20 Jun 2019 10:36 AM PDT

Facebook Prineville Data Center

Libra, Facebook's new cryptocurrency, is expected to have a smaller environmental footprint compared to some of its more notorious blockchain brethren, including bitcoin, according to experts. Its energy demands are projected to be more like those of existing data centers — which, while still demanding, aren't quite as energy-hungry as mining bitcoins.

The currency hasn't launched yet, so it's hard to know how those claims will stack up against reality. But its design — more centralized than most cryptocurrencies — means that Libra will likely draw less energy. Unlike its more decentralized peers, only a few trusted members of the Libra Association, the centralized hub for the currency, can create Libra.
