Tim Cook condemns ‘repulsive’ racist violence in Charlottesville

Tim Cook made his stance about Charlottesville clear enough by tweeting out that “violence and racism have no place in America” as the tragic events were unfolding. This internal letter sent to employees that Recode obtained, however, will give you even more insight into where he stands. Apple’s head honcho wrote that Americans must unequivocally reject hate and bigotry in the country. It’s not about “left or the right, conservative or liberal,” but “about human decency and morality.” He stressed that he disagrees with the President and other people who “believe that there is a moral equivalence between white supremacists and Nazis, and those who oppose them by standing up for human rights.”

Cook also revealed that Apple will be donating $1 million each to the Southern Poverty Law Center (SPLC) and the Anti-Defamation League to help both organizations working to get rid of hate. In addition, Apple will match its employees’ donations to human rights groups 2-for-1 until September 30th. You can look forward to a new iTunes feature that will make it easy to donate to SPLC, as well.

Over the past few days, the President has lost the support of many other high-profile tech personalities due to his actions. Intel CEO Brian Krzanich, Jeff Immelt of GE and a list of other executives from other industries left his manufacturing council and other advisory boards following the events in Charlottesville. (Elon Musk peaced out way back when the administration decided to leave the Paris climate agreement.)

Unlike those execs, the Apple CEO never had a close relationship with the President. He worked with Trump when it came to tax reform and used his influence to talk to the President’s people about improving LGBTQ+ rights, but he butted heads with the administration over the Muslim immigration ban and its stance on climate change. His position might not be that surprising, but it’s good to know where people, especially powerful ones like Cook, stand. Here’s the CEO’s full letter to his employees:

Team,

Like so many of you, equality is at the core of my beliefs and values. The events of the past several days have been deeply troubling for me, and I’ve heard from many people at Apple who are saddened, outraged or confused.

What occurred in Charlottesville has no place in our country. Hate is a cancer, and left unchecked it destroys everything in its path. Its scars last generations. History has taught us this time and time again, both in the United States and countries around the world.

We must not witness or permit such hate and bigotry in our country, and we must be unequivocal about it. This is not about the left or the right, conservative or liberal. It is about human decency and morality. I disagree with the president and others who believe that there is a moral equivalence between white supremacists and Nazis, and those who oppose them by standing up for human rights. Equating the two runs counter to our ideals as Americans.

Regardless of your political views, we must all stand together on this one point — that we are all equal. As a company, through our actions, our products and our voice, we will always work to ensure that everyone is treated equally and with respect.

I believe Apple has led by example, and we’re going to keep doing that. We have always welcomed people from every walk of life to our stores around the world and showed them that Apple is inclusive of everyone. We empower people to share their views and express themselves through our products.

In the wake of the tragic and repulsive events in Charlottesville, we are stepping up to help organizations who work to rid our country of hate. Apple will be making contributions of $1 million each to the Southern Poverty Law Center and the Anti-Defamation League. We will also match two-for-one our employees’ donations to these and several other human rights groups, between now and September 30.

In the coming days, iTunes will offer users an easy way to join us in directly supporting the work of the SPLC.

Dr. Martin Luther King said, “Our lives begin to end the day we become silent about the things that matter.” So, we will continue to speak up. These have been dark days, but I remain as optimistic as ever that the future is bright. Apple can and will play an important role in bringing about positive change.

Best,
Tim

We’ve seen the terror of white supremacy & racist violence before. It’s a moral issue – an affront to America. We must all stand against it

Latest LG V30 render leak shows front, back and sides in full

The LG V30 has leaked yet again, showing a similar design to the G6.

The LG V30 is scheduled to be announced on August 31 at IFA, but we’ve been getting a steady bit of information as that date gets closer. LG has already announced the phone will feature special haptics to provide for an “innovative touch experience,” and LG has confirmed the 6-inch OLED display with small bezels that look a lot like the G6.

@evleaks has now released a full render of the upcoming device, showing much more of the hardware design than previous leaks. The V30 overall looks like a mix of the LG G6 and the Samsung Galaxy S8 — not that that’s a bad thing. It confirms the combined power button and fingerprint sensor will be in on the back of the device, near the middle for easy reaching (unlike the GS8). Also shown is the dual camera system, next to the flash and what looks like a laser autofocus.

The V30 is shaping up like an LG G6 and Galaxy S8 smashed together.

One key missing component, of course, is the second screen — but as we know already LG’s goal was to reduce the overall size of the phone while keeping the screen large. While the second screen may have been useful for some, LG obviously doesn’t feel it was compelling enough to justify the compromises in size. The front and bottom of the phone are not shown, but other leaks have shown the phone will feature a 3.5mm headphone jack.

Are you looking forward to the LG V30? Let us know down below!

• Latest render shows LG V30 alongside Galaxy Note 8
• LG V30 will have curved OLED display

Ford patents removable wheel and pedals for future autonomous cars

Lawmakers have cautiously supported automakers’ experiments with self-driving vehicles, but they’ve been split on whether cars need a steering wheel at all times in case humans need to take over. But with more and more concepts ditching control elements (wheels, pedals, gear shifts) entirely, it’s likely a matter of time before those wholly autonomous options head to consumers. In the meantime, Ford has received a patent that splits the difference: A wheel and pedals that are completely removable.

Ford actually filed the patent in February 2016, and it was awarded to the automaker last week on August 10th, as originally reported by Motor1. It’s not a perfect solution, the document notes: Designers will have to reconsider how they implement airbags, which are traditionally situated in the steering wheel. Ford’s patent proposes one in both the wheel and dashboard behind it, electronically switching off the latter if the wheel column is locked in.

But it isn’t just about popping a wheel in and out: This redesign would probably require major structural changes, as the steering column is an integral part of any car’s frame. While this is only a patent, it shows that automakers are thinking hard about steering and control compromises that will let them sell autonomous vehicles in countries with different legal requirements — along with users who might just want to take the wheel from time to time.

Squarespace pulls hate sites from its web hosting service

The post-Charlottesville crackdown on internet hate speech is expanding at a very rapid pace. Squarespace, the web design and hosting service, has revealed to The Verge that it’s removing a “group of sites” for violating its policy banning advocacy of bigotry and hate. The company isn’t saying which sites are getting the axe, but it’s giving the affected producers 48 hours’ notice before their pages vanish.

The move to remove hate material began in earnest when GoDaddy pulled the domain registration for the Daily Stormer after the neo-Nazi site tried to justify the murder of protester Heather Heyer through character attacks. It quickly snowballed from there: Google canceled the site’s attempt to switch to its domain service, and other internet giants quickly started banning hate-oriented campaigns and communities.

In most cases, the providers say the issue isn’t hate speech by itself, but the tone it has taken since the ‘alt-right’ Charlottesville march. White supremacist sites celebrated or excused Heyer’s murder, and providers saw that as actively promoting violence. However, the issue is quickly becoming a hot potato — internet firms don’t want to appear as if they condone white supremacists in any form, whether or not they were involved in the recent violence. This won’t please free speech advocates who believe non-violent material should stay, but they’re unlikely to sway private companies who both have the legal freedom to host what they want and a concern that they’ll lose customers if they let hateful material remain.

AT&T Again Giving New DirecTV Now Subscribers a Free Apple TV

AT&T today announced that it’s reactivated a deal offering new DirecTV Now subscribers a free 32GB fourth-generation Apple TV with the purchase of a 3-month prepaid DirecTV Now subscription.

A DirecTV NOW subscription starts at $35 per month for the most basic package, so subscribers will need to pay $105 up front to get the deal. AT&T offered a similar deal back when the service first launched, but the original promotion ended months ago.

To get the free Apple TV, new subscribers will need to sign up for DirecTV now at an AT&T Retail or Authorized Retail Store, or through an AT&T Call Center. The deal is not available online.

While pricing for DirecTV Now starts at $35 for 60 channels, AT&T’s other pricing plans include $50 per month for 80+ channels, $60 per month for 100+ channels, and $70 per month for 120+ channels. HBO and Cinemax are also available for an additional $5 each per month.

AT&T says the Apple TV deal will be available while supplies last.

Zooming photos is finally a thing for image-driven Pinterest

Pinterest is adding a couple of new features to help you get more use out of it. First, the app now (finally) allows you to pinch to zoom in on Pins, which it said in a blog post is one of its most requested features. Not surprising as it has been building itself to be a visual search engine and the lack of zooming ability has been noticeably absent. It has also tweaked its visual search tool, which lets you select an object within a Pin and find items that are similar. The visual search button has been moved and made to be more noticeable. Pinterest says that in tests, 70 percent more people used the tool after the changes were made. Finally, those using visual searches through Chrome don’t need to have a Pinterest account to do so any longer.

The app has seen a few changes of late that have given a lot of added functionality. Earlier this year it launched Lens, which allows users to take pictures and then find Pins related to objects in the photo. Updates in May then made it possible to search multiple items in the same pic and find recipes based on photos of food. And recently, Pinterest gave Lens the capability to help users put together outfits and find new clothes they might like.

The new zoom feature starts rolling out to iOS users today and Pinterest says Android users will get access to it soon.

Motorola designed a phone screen that repairs itself

Motorola doesn’t just want to make phone screens that are shatter-resistant… if it has its way, what cracks that do show up could be fixed on the spot. It recently applied for a patent on a phone screen whose shape memory polymer heals damage when you subject it to rapid changes in heat. The phone itself could produce the heat (Motorola even envisions an app that tells the phone where to start repairs), but your body heat, a dock or a plug-in panel might also work.

This seems like a dream for anyone who’s ever smashed a phone screen. However, there are bound to be a few caveats. First, of course, is that this is a patent application — there’s no guarantee that Motorola or parent company Lenovo has something in the cards. And just like Motorola’s anti-shatter screens, this may be an exercise in compromise. A polymer screen probably won’t feel as nice to the touch as glass, and the technology never completely restores the screen’s strength. If you’re a butterfingers type, you might still have to take your phone in after enough abuse. This beats having to pay through the nose for a single fix, though, and it could easily make sense for rugged devices where drops are virtually expected.

All the Apple iMac Pro news you can handle: Xeon inside and a star-studded GPU

Why it matters to you

Here’s all the Apple iMac Pro news you can chew on to better understand what’s inside Apple’s upcoming all-in-one workstation with a $5,000 starting price.

On June 5, 2017, Apple revealed the iMac Pro, the next installment in its family of iMac workstations. Starting at a meaty $5,000, the all-in-one device will sport an Intel Xeon processor with up to 18 cores, an AMD professional graphics card with up to 22 teraflops of graphics computations, and an attractive new Space Gray enclosure seemingly ripped out of the future. That said, here is all the current Apple iMac Pro news we could dig up.

Xeon inside

First, we’re not entirely sure what processors Apple will be using in December. The company lists Intel “Xeon” chips with eight, 10, and 18 cores, but no specific models. For a while, signs have pointed to the possibility that Apple may be using Intel’s just-announced Xeon “Purley” processors based on the Skylake-SP architecture. The belief is that if Apple relied on Intel’s existing crop of Haswell-based Xeon E5 and E7 chips, then the iMac Pro would already be on the market.

But a leaked slide regarding Intel’s three-year Xeon processor roadmap positions the “Basin Falls” one-socket workstation platform for the end of 2017. It will be based on the Skylake Server Socket R, aka Socket R4, or better known as LGA 2066, the same socket used by Intel’s latest X-Series chips for the enthusiast desktop market. This socket only supports four memory modules, which is what we see in product images of the iMac Pro’s internals provided by Apple (shown below).

Meanwhile, the new “Purley” Platinum and Gold Xeon processors rely on the LGA 3647 socket (Socket P). Those chips are meant for scalable, datacenter servers with two processors or more, and the CPU family itself doesn’t even offer a 10-core model at the time of this publication. Adding to that, the LGA 3647 socket supports six memory modules, which would be overkill for Apple’s all-in-one workstation.

The latest rumor, then, is that the three Xeon processors installed in Apple’s upcoming iMac Pro will be based on three Intel X-Series processors. According to Apple’s own website, iMac Pros will have “Turbo Boost speeds up to 4.5GHz,” matching the maximum speeds of two of the three chips listed below. This rumor stems from digging around in the source code of the MacOS High Sierra developer beta, which lists the “Basin Falls” and “Purley” code-names.

But Apple says the iMac Pro’s Xeon processors will have up to 42MB in cache, indicating that the X-Series chip foundation will outfitted for the professional workstation environment. But again, all of this is mere speculation, and we won’t know any solid Xeon details until the iMac Pros hit the market in December.

Still, here are the processors Intel may be refitting and re-branding for use in workstations:

Cores / Threads

Base Speed

Maximum Speed

Cache

Power Use

Core i9-7980XE
18 / 32
2.60GHz
4.40GHz
24.75MB
165 watts
Core i9-7900X
10 / 20
3.30GHz
4.50GHz
13.75MB
140 watts
Core i7-7820X
8 / 16
3.60GHz
4.50GHz
11MB
140 watts

Note that the eight-core ($600) and 10-core ($1,000) models are available on the enthusiast desktop market now. The 18-core model won’t arrive until September 25 for $2,000.

Keeping the processor, graphics chip, and memory inside cool are two blowers mounted in the upper half of the iMac Pro. These two blowers turn in opposite directions to pull air into the workstation through a long slit running across the bottom of the back plate. This air is pulled up across the memory and storage, and then pushed down across the massive heatsink covering the processor . The warm air appears to be pushed out through a discrete vent hidden from view by the iMac Pro’s stand. Heatpipes appear to connect the heatsink to the system memory, Radeon Pro Vega graphics chip, and storage as well.

Performance graphics pulled from the stars

With the introduction of the upcoming iMac Pro came a quiet reveal that they would have options for two unannounced graphics cards by AMD: the Radeon Pro Vega 64, and the Radeon Pro Vega 56. They’re currently not on the market, nor has AMD provided any information about these two cards. But the names indicate they’re closely related to the two add-in cards released for the desktop PC gaming market on August 14 – the Radeon RX Vega 64, and the Radeon RX Vega 56. There are a few similarities to AMD’s upcoming Radeon Pro WX 9100 cards for workstations, too.

Here’s how they fit into AMD’s Vega-based graphics chip lineup (not including the Radeon Pro SSG):

As the chart shows, the “Pro” Vega 64 model will supposedly have twice the on-board memory than the “RX” 64 version, which is already available. We don’t know its base and boost speeds just yet, and both performance numbers appear to be carbon copies of the “RX” numbers for now, until AMD releases official information. How the Pro Vega 64 and the Pro WX 9100 card will differentiate from each other could be in their feature sets.

The specifications really speak for themselves. There’s enough hardware to optimally run a virtual reality headset, such as the HTC Vive shown on the product page. There are no physical video outputs, so adding external displays must be done through the provided Thunderbolt 3 ports, which support the DisplayPort protocol. One Lightning-to-USB cable is provided, but you’ll need to purchase Type-C cables/adapters supporting Thunderbolt 3 and your external display’s port (VGA, HDMI, DVI, or DisplayPort).

Based on Apple’s live diagram, the iMac Pro’s speakers are mounted towards the top near the two cooling fans. But the company has designed the internals to where the output audio is directed downwards and through the long slit lining along the bottom back of the all-in-one PC. Apple says these two speakers deliver “broad frequency response, rich bass, and more volume” even though they’re packed under the iMac Pro’s rear hood.

“We re engineered the whole system and designed an entirely new thermal architecture to pack extraordinary performance into the elegant, quiet iMac enclosure our customers love — iMac Pro is a huge step forward and there’s never been anything like it,” said John Ternus, Apple’s vice president of Hardware Engineering.

What’s not crystal clear is what type of SSD Apple is using in the iMac Pro. For starters, any SSD will be faster than using a clunky mechanical drive, because they don’t rely on spinning discs for reading information like a compact record player. But the fastest SSDs can access data lanes typically used by add-in-cards (PCI Express), which are around five times faster than lanes typically used by storage devices (SATA 3).

For instance, a 2.5-inch hard drive with platters moving at 7,200RPM typically have a read speed of 80 to 160MB per second. A decent 2.5-inch SSD using the same SATA 3 connection can have a read speed of around 540MB per second. That’s a huge performance increase, but a stick-sized SSD using a PCI Express-based connection could have read speeds of around 2,500MB per second or higher.

Apple’s standard iMacs have been somewhat disappointing in storage performance because they come standard with a “Fusion” hard drive, that matches a small solid state storage cache with a large mechanical hard drive. However, Apple’s MacBook line has some of the quickest storage options around, so the company does know how to use the latest storage tech. Given it’s price and purpose, we think it’s a good bet the iMac Pro will come standard with a solid state drive connected over PCI Express.

Finally, as previously reported, the iMac Pro will ship with a keyboard and mouse in a unique Space Grey color, and they won’t be made available to purchase as standalone peripherals.

Apple gets high with MacOS

Powering the iMac Pro will be Apple’s MacOS High Sierra operating system. Apple provides a glimpse of the platform here, such as a new file system with a not-so-creative name (Apple File System), support for the high-definition HEVC (H.265) video codec, Metal 2 graphics, and support for high-definition VR headsets. Other features include a handful of revamped apps, a better Safari browser, and improvements to Siri.

“Siri has a more natural voice, with more changes in expression, intonation, and emphasis based on what it’s saying. In other words, your personal assistant sounds more like a person — whether it’s telling a joke or helping you find that presentation from last week,” Apple says.

You can actually give MacOS High Sierra a run now by heading here. Just sign up for the Apple Beta Software Program to download and use a pre-release of the platform. Enrollment also provides you with access to the latest preview builds of iOS and tvOS as well.

So how much is the workstation and when can I get it?

Right now, Apple doesn’t provide an exect date, but merely states that the iMac Pro will be available in December. The starting price will be a massive $5,000, so you’ll have to smash your piggy bank to afford it.

Imaginative AI dreams up its own high-resolution street scenes

Why it matters to you

Impressive AI demonstration could be a useful tool for animators and video game designers, as well as making machines smarter.

Remember when Apple had its disastrous launch of Apple Maps in 2012 and real-world geography suddenly received a dose of accidental “creativity” which replaced hospitals with supermarkets and turned bridges into death slides? Well, researchers at Stanford University and Intel have just debuted a new project which creates imaginary street scenes — except these folks have done it on purpose.

What the researchers have developed is an imaginative artificial intelligence that can create photorealistic Google Street View-style images of fake street scenes. These scenes are rendered in highly detailed 1,024 x 2,048 HD resolution.

A bit like a comic artist who draws a city backdrop by taking photo references from different places and weaving them together, the street scenes Stanford and Intel’s AI imagines are based on individual elements it saw during its training — and then combines them to create novel images. The technology that makes this possible is something called a cascaded refinement network, a type of neural network designed to synthesize HD images with a consistent structure. Like a regular neural network, a cascaded refinement network features multiple layers, which it uses to generate features one layer at a time. Each layer has a higher resolution than the layer which came before it. Layers receive a coarse feature from the previous layer and then compute the details locally; allowing synthesized images to be generated in a consistent way.

The result? Street images equivalent to a photo taken with a two-megapixel camera.

While the work is an interesting example of computational creativity in its own right (think Google’s DeepDream or the Massachusetts Institute of Technology’s Nightmare Machine for other examples), this project’s creators think it has multiple real-world applications.

“One application is a new rendering pipeline for video games and animations,” Qifeng Chen, a Stanford Ph.D. researcher on the project, told Digital Trends. “We do not need artists to create the virtual scenes manually. An AI painter can automatically learn from real images and translate the real world content to the virtual world in video games and movies. This approach can save a lot of human labor and potentially synthesize photo-realistic images. The second motivation is that mental imagery is believed to play an important role in decision making and the ability to synthesize photo-realistic images may support the development of artificially intelligent systems.”

Right now, the project is only able to create variations on German streets, because these are the images it was trained on. Going forward, however, it could be possible for the system to expand its knowledge to generate streets styled after any city in the world.
