The latest barrier to 5G speeds? The summer

Ars Technica - July 12, 2019 - 7:08pm

Enlarge / 5G is here, but that doesn't mean you have to buy into it.

Thermal throttling is a fact of life for smartphones. SoCs generate a lot of heat, and when this heat can't be dissipated, processors react by slowing down and thereby generating less heat. Usually this is just an issue for heavy 3D gaming sessions or a phone directly exposed to sunlight for a long time, like when mounted on a car windshield. In the era of 5G, though, heat is also an issue for your modem.

While the vast majority of people don't yet have access to a 5G phone or 5G service, PCMag's Sascha Segan has been flying around the country testing out the carriers' nascent implementation of 5G. So far, the heat generated by Qualcomm's first-generation chips is an issue. Segan writes:

On a hot Las Vegas morning, my two Galaxy S10 5G phones kept overheating and dropping to 4G. This behavior is happening with all of the millimeter-wave, first-generation, Qualcomm X50-based phones when temperatures hit or exceed 85 degrees. We saw it with T-Mobile in New York, with Verizon in Providence, and now with AT&T in Las Vegas. It's happened on Samsung and LG phones, with Samsung, Ericsson, and Nokia network hardware.

As we wrote back in December, Qualcomm's first-generation 5G design is a significant regression from the fully integrated 4G chips we've been used to. A modern 4G LTE smartphone packs everything into a single main chip, which houses all of the usual computer components along with the LTE modem. Today's 5G design requires that same chip, along with a separate chip for the 5G mmWave modem and several more chips for the mmWave antenna modules. The result is that 5G takes up a lot more space and generates a lot more heat than 4G, and when this heat gets to be too much, all that 5G circuitry just shuts off.

US gov’t growing a record 2-ton cannabis crop—but still won’t let others grow

With the recent explosion of cannabis access and CBD products, federally funded scientists are craving more research on the potential risks and benefits. But if any researchers were hoping for more varied sources of cannabis—sources that could better reflect what patients have access to, for instance—they may be left holding their breath.

Three years after saying it wanted more suppliers of cannabis for research, the US government continues to hold a monopoly on growing the crop. While more than two dozen entities have submitted applications to the Drug Enforcement Administration to become growers, the government has dragged its feet in processing the paperwork and is instead stepping up its own crop; its exclusive supplier, the University of Mississippi, is growing 2 tons this year, the largest crop in five years, according to a report by the Associated Press.

Orthopedics researcher Emily Lindley at the University of Colorado and other researchers are not happy with the situation, according to the AP. Lindley, who is studying whether cannabis with high THC levels could be an alternative to addictive opioids for chronic back pain, says she wants more suppliers than just Ole Miss, which has had limited strain varieties and product availability. “We want to study what our patients are using,” she said.

Evidence points to another Switch hardware revision on the horizon

Ars Technica - July 12, 2019 - 5:44pm

Enlarge / Could changes be coming to the Tegra X1 chip that powers the Nintendo Switch?

Wednesday's announcement of the Switch Lite put to rest months of credible rumors that a miniature, portable-focused Switch was on the horizon. But Nintendo still has yet to confirm the other side of some of those rumors: suggestions that the company is planning to upgrade the Switch's internal hardware in the near future.

Nintendo CEO Doug Bowser recently told CNET that no further updates to the original Switch hardware are coming this year. But that hasn't stopped Nintendo-watchers from trying to glean information about Nintendo's future hardware plans from various tea leaves.

Following the evidence

The most concrete of these hints is an FCC request (noticed by The Verge) that Nintendo filed July 2, seeking a "class II permission change" for the original Switch model. The request says the new hardware revision will feature a "change of SoC type," a "change of NAND memory type," and a new CPU board to accommodate those changes.

Charter Communications has received final approval to stay in New York State despite violating merger commitments related to its 2016 purchase of Time Warner Cable.

The New York State Public Service Commission (PSC) had revoked its approval of the merger and ordered Charter to sell the former Time Warner Cable system in July 2018. Charter repeatedly failed to meet deadlines for broadband expansions that were required in exchange for merger approval, state officials said.

But Charter and state officials struck a deal in April, and yesterday the PSC approved the settlement.

On Friday, Ford and Volkswagen made official news that first leaked last week. The pair are strengthening their alliance to work together on those hottest of emerging automotive technologies, electric vehicles and autonomous driving.

Equal partners in Argo AI

VW will become an equal partner in the self-driving startup Argo AI, putting in $1 billion in cash and another $1.6 billion in the form of Audi's Autonomous Intelligent Driving spinoff, which will become Argo AI's European center of operations. Over the next three years, VW will also buy an additional $500 million of Argo AI shares from Ford. (Ford will still complete its billion-dollar investment in Argo AI). Until now, Argo AI has operated as a de facto Ford subsidiary, but this investment makes VW an equal partner, with the remaining shares in the company reserved for employee compensation.

Argo AI's technology will be incorporated into both Ford and VW vehicles as part of each company's plans to offer geofenced driverless robotaxis or goods delivery services in the US and Europe. "While Ford and Volkswagen remain independent and fiercely competitive in the marketplace, teaming up and working with Argo AI on this important technology allows us to deliver unmatched capability, scale, and geographic reach," said Ford President and CEO Jim Hackett in a statement.

Donald Trump is not a fan of Libra, Facebook's proposed cryptocurrency, the president made clear in a series of tweets on Thursday evening.

"Facebook Libra’s 'virtual currency' will have little standing or dependability.," Trump tweeted. "If Facebook and other companies want to become a bank, they must seek a new Banking Charter and become subject to all Banking Regulations, just like other Banks."

Trump is the latest—and most high-profile—public official to raise doubts Facebook's cryptocurrency plans. On Wednesday, Federal Reserve chairman Jerome Powell warned that "Libra raises many serious concerns regarding privacy, money laundering, consumer protection and financial stability."

Amazon Music Unlimited is growing faster than Apple Music or Spotify, report says

Amazon grew its Music Unlimited streaming service by more than 70% in the past year, according to data by Midia Research published by the Financial Times. The service currently has approximately 32 million subscribers. However, the report didn't clarify whether that includes trial subscriptions as well as paid ones.

Amazon Unlimited Music is still smaller than its biggest competitors. Apple services head Eddie Cue recently revealed that Apple Music has about 60 million subscribers. Spotify has more than 100 million. Google has offered a variety of streaming services via YouTube that it has shuttered, rebranded, and shuffled around, making it difficult to quantify the company's traction with music listeners. In any case, Amazon still has a lot of catching up to do.

Midia Research credits the rapid growth of Amazon Unlimited Music to the proliferation of Amazon Echo smart speakers and other devices with Alexa. While these devices can play music from other services like Spotify, they default to Amazon services in many cases. For example, if you ask Alexa to play David Bowie's "Heroes" on a Sonos One speaker, Amazon's streaming music service will be used. You have to say "Play David Bowie's 'Heroes' on Spotify" to get a different result.

The 2019 Volkswagen Golf R is king of the hot hatches

Ars Technica - July 12, 2019 - 12:15pm

From its earliest days, the automobile has been a status symbol, where badge has mattered often as much as engineering. There's a human tendency to pigeonhole, and we infer much about a person simply by knowing what they drive. Occasionally though, something comes along that transcends this class structure: the original Mini, which appealed to the smart set in 1960s Europe, for instance; or the Ford F-150, used as often to commute to an office as to a construction site. The Volkswagen Golf definitely falls into that category.

When it was first launched in Europe in 1974, the Mk1 Golf was utilitarian, a people's car to replace the Beetle. But the secret of a classless car is that it's anything but. Peter Sellers might have driven a Mini at the height of stardom, but his was lavishly trimmed by the coachbuilder Radford. Suburban dads can spend as much on a leather-lined F-150 as they could on a big BMW the way their forebears did in the '90s. And the Golf broke out of being a mere people's car when it added the GTI to the lineup. VW didn't invent the hot hatch, but it did execute it probably better than anyone else. The company certainly advertised it better, and the car was as popular with yuppies as it was with middle-class moms.

Take a GTI and turn it up to 11

More recently, VW decided it could sell even more Golfs if it added a variant above the giant-killing GTI—enter the Golf R. If the idea behind a GTI was to take a front-wheel-drive hatchback and give it more power and better suspension, the R takes it a bit further. Now there's an even more powerful engine—a 2.0L turbocharged direct-injection four-cylinder with 288hp (215kW) and 280lb-ft (380Nm). To achieve this with VW's ubiquitous EA888 engine, the R engineers gave it a new cylinder head (plus valves and springs), a new turbocharger, new pistons, and a new injection system.
