Twitter is introducing a new toggle in the app to allow users to switch from the ranked timeline to the original, reverse-chronological feed. "The company says the move comes in recognition of the fact that Twitter is often most useful in real time, particularly during live events such as sports games or the Oscars," reports The Verge. From the report: The latest incarnation of the original Twitter feed can be accessed by tapping the cluster of small stars -- the company calls it the "sparkle" and now so shall we all, forever -- and switching to see the latest tweets. Over time, the company will learn your behavior. If you routinely switch to the latest tweets, Twitter will default you to them. This marks a change from the past, when the app would switch you back to the ranked timeline at unpredictable intervals.

An anonymous reader quotes a report from Ars Technica: T-Mobile has denied an allegation that it lied to the Federal Communications Commission about the extent of its 4G LTE coverage. A group that represents small rural carriers says that T-Mobile claimed to have 4G LTE coverage in places where it hadn't yet installed 4G equipment. That would violate FCC rules and potentially prevent small carriers from getting network construction money in unserved areas. T-Mobile said the allegations made by the Rural Wireless Association (RWA) in an FCC filing on Friday "are patently false."

"RWA's misrepresentations are part of an ongoing pattern of baseless allegations by the organization against T-Mobile designed to delay or thwart competition in rural America and deprive rural Americans of meaningful choice for broadband services," T-Mobile wrote. "The organization's repeated disregard for fact-based advocacy is a disrespectful waste of Commission time and resources." RWA members have conducted millions of speed tests at their own expense to determine whether the major carriers' coverage claims are correct. The RWA says both Verizon and T-Mobile have exaggerated coverage, and the FCC is taking the allegations seriously. FCC Chairman Ajit Pai announced last week that the FCC has begun an investigation and that a preliminary review of speed-test data "suggested significant violations of the Commission's rules." The FCC has not said which carrier or carriers violated the rules.

"Anthony Levandowski, the controversial engineer at the heart of a lawsuit between Uber and Waymo, claims to have built an automated car that drove from San Francisco to New York without any human intervention," reports the Guardian. Levandowski told the Guardian that he completed the 3,099-mile journey on October 30th using a modified Toyota Prius, which "used only video cameras, computers and basic digital maps." From the report: Levandowski told the Guardian that, although he was sitting in the driver's seat the entire time, he did not touch the steering wheels or pedals, aside from planned stops to rest and refuel. "If there was nobody in the car, it would have worked," he said. If true, this would be the longest recorded road journey of an autonomous vehicle without a human having to take control. Elon Musk has repeatedly promised, and repeatedly delayed, one of his Tesla cars making a similar journey. A time-lapse video of the drive, released to coincide with the launch of Levandowski's latest startup, Pronto.AI, did not immediately reveal anything to contradict his claim. But Levandowski has little store of trust on which to draw.

Kroger is launching its unmanned grocery delivery service in Scottsdale, Arizona. The company first announced the pilot with robotics company Nuro in June, and since August, "they have tested an autonomous fleet of 'a handful of' Priuses with safety drivers just in case someone needed to intervene," reports Adweek. "Together, they have completed nearly 1,000 deliveries in Scottsdale." From the report: Now, Kroger is adding two R1 unmanned vehicles to its fleet, which Nuro designed to transport goods on public roads without passengers and marks the first deployment of its technology for the general public. (The Priuses will continue to have safety drivers.) To start, deliveries are available from a single store in the "Kroger Family," the Fry's Food Store at 7770 East McDowell Road. A Kroger rep said customers who live within the store's zip code -- 85257 -- will have access to the service. Customers place orders online or via the Fry's app. An announcement said same- and next-day delivery is available. All orders have a $5.95 fee, but there is no minimum for order total.

An anonymous reader quotes a report from Ars Technica: We seem to be on the cusp of a revolution in storage. Various technologies have been demonstrated that have speed approaching that of current RAM chips but can hold on to the memory when the power shuts off -- all without the long-term degradation that flash experiences. Some of these, like phase-change memory and Intel's Optane, have even made it to market. But, so far at least, issues with price and capacity have kept them from widespread adoption. But that hasn't discouraged researchers from continuing to look for the next greatest thing. In this week's edition, a joint NIST-Purdue University team has used a material that can form atomically thin sheets to make a new form of resistance-based memory. This material can be written in nanoseconds and hold on to that memory without power. The memory appears to work via a fundamentally different mechanism from previous resistance-RAM technologies, but there's a small hitch: we're not actually sure how it works. The two mechanisms used to change the resistance have been reported in the journal Nature Materials.

Even if you explicitly tell Facebook to not track your location, it says it will still use your IP address to track your location. Kashmir Hill, reporting for Gizmodo: Aleksandra Korolova has turned off Facebook's access to her location in every way that she can. She has turned off location history in the Facebook app and told her iPhone that she "Never" wants the app to get her location. She doesn't "check-in" to places and doesn't list her current city on her profile.

Despite all this, she constantly sees location-based ads on Facebook. She sees ads targeted at "people who live near Santa Monica" (where she lives) and at "people who live or were recently near Los Angeles" (where she works as an assistant professor at the University of Southern California). When she traveled to Glacier National Park, she saw an ad for activities in Montana, and when she went on a work trip to Cambridge, Massachusetts, she saw an ad for a ceramics school there. Facebook was continuing to track Korolova's location for ads despite her signaling in all the ways that she could that she didn't want Facebook doing that.

[...] "There is no way for people to opt out of using location for ads entirely," said a Facebook spokesperson by email. "We use city and zip level location which we collect from IP addresses and other information such as check-ins and current city from your profile to ensure we are providing people with a good service -- from ensuring they see Facebook in the right language, to making sure that they are shown nearby events and ads for businesses that are local to them."

Google has listened to user feedback and is currently testing a feature that will let G Suite users invite non-Google account holders to view, comment, suggest edits, and even directly edit Google Docs, Sheets, and Slides files. From a report: This wasn't possible until now, and G Suite users could only share documents and request feedback from users that owned a Google account. The way this new feature will work is via PINs (Personal Identification Numbers). Google said that G Suite users would be able to invite a non-Google user to view or edit a document via email. The said email would contain a link to the shared document. Non-Google users will be able to access the link and request an PIN that it would be delivered via a second email. Once they enter the PIN code, users can then view or edit the shared file -based on the assigned permissions.

London's Metropolitan Police is testing its facial recognition technology in the capital this week. From a report: It's the seventh time the Metropolitan Police, the UK capital's police force, has trialled facial recognition in public. The technology has previously been used at large events, including Notting Hill Carnival in 2016 and 2017, and Remembrance Day services last year. This year, the technology is being used Monday and Tuesday of this week in Soho, Piccadilly Circus, and Leicester Square -- all major shopping areas in the heart of the city.

Cameras are fixed to lampposts or deployed on vans, and use software developed by Japanese firm NEC to measure the structure of passing faces. This scan is then compared to a database of police mugshots. The Met says a match via the software will prompt officers to examine the individual and decide whether or not to stop them. Posters will inform the public they're liable to be scanned while walking in certain areas, and the Met says anyone declining to be scanned "will not be viewed as suspicious."

Amazon may have turned off its Oracle data warehouse in favor of Amazon Web Services database technology, but no one else in their right mind would, Oracle's outspoken co-founder and CTO Larry Ellison says. From a report: "We have a huge technology leadership in database over Amazon," Ellison said on a conference call following the release of Oracle's second quarter financial results. "In terms of technology, there is no way that... any normal person would move from an Oracle database to an Amazon database." During last month's AWS re:Invent conference, AWS CTO Werner Vogels gave an in-the-weeds talk explaining why Amazon turned off its Oracle data warehouse. In a clear jab at Oracle, Vogels wrote off the "90's technology" behind most relational databases. Cloud native databases, he said, are the basis of innovation.

The remarks may have gotten under Ellison's skin. Moving from Oracle databases to AWS "is just incredibly expensive and complicated," he said Monday. "And you've got to be willing to give up tons of reliability, tons of security, tons of performance... Nobody, save maybe Jeff Bezos, gave the command, 'I want to get off the Oracle database." Ellison said that Oracle will not only hold onto its 50 percent relational database market share but will expand it, thanks to the combination of Oracle's new Generation 2 Cloud infrastructure and its autonomoius database technology. "You will see rapid migration of Oracle from on-premise to the Oracle public cloud," he said. "Nobody else is going to go through that forced march to go on to the Amazon database."

AT&T said Tuesday its network is now live in parts of 12 cities across the United States, with the first mobile 5G device arriving on Friday, December 21. From a report: According to an AT&T spokesperson, the company's 5G network is already up and running in parts of the previously promised dozen cities: Atlanta, Charlotte, Dallas, Houston, Indianapolis, Jacksonville, Louisville, Oklahoma City, New Orleans, Raleigh, San Antonio, and Waco. However, the first consumer device that will be able to access that network, Netgear's Nighthawk 5G Mobile Hotspot, will become available just ahead of the Christmas holiday.

The company also revealed that it will be using the name "5G+" for the part of its network that will use millimeter wave spectrum and technologies, and it said the Nighthawk 5G Mobile Hotspot will run on that 5G+ network. [...] AT&T's 5G pricing is also interesting. Like Verizon, AT&T is offering an initial promotion that makes the hardware and 5G service cheap up front, with new pricing set to follow later. Early adopters from the consumer, small business, and business markets will be able to "get the mobile 5G device and wireless data at no cost for at least 90 days," AT&T says, with new pricing beginning in spring 2019. At that point, the Nighthawk 5G Mobile Hotspot will cost $499 outright, with 15GB of 5G service priced at $70 per month, which AT&T calls "comparable" to its current $50 monthly charge for 10GB of 4G data.

Sphero's hinted that it's getting out of the licensed product game, but this week CEO Paul Berberian confirmed that the company is clearing out its remaining licensed inventory and won't be restocking the supply. From a report: That means the company won't be producing any more BB-8s, R2-D2s, Lightning McQueen cars, or talking Spider-Mans. The listings for all the toys list them as "legacy products" that are no longer in production. App support will continue for "at least two years, if not longer," Berberian says. The Disney partnership lasted three years, but ultimately, the licensed toy business required more resources than it was worth, Berberian tells The Verge. These toys sold well when released with a movie, but interest waned over time as the movie became more distant, he says. Still, the company sold "millions" of BB-8s, although company data shows that the toys weren't used much after initial play time and eventually sat on shelves.

They say revenge is a dish best served cold. But for Mark Rober, it's much sweeter served smart, smelly and covered in glitter. From a report: The former NASA engineer-turned-YouTube star has received plaudits online after designing a booby trap to avenge all those who've fallen victim to a new wave of neighborhood crime: doorstep delivery theft. Rober spent six months combining GPS tracking, cameras, fart spray and glitter in an elaborate and amusing mechanism after discovering thieves had stolen an Amazon delivery from his doorstep.

In a video posted on his channel, the 38-year-old, who helped design the U.S. space agency's Curiosity Rover, said his engineering experience left him well-placed to "take a stand" after dismissive police left him feeling "powerless." "If anyone was going to make a revenge ... package and over-engineer the crap out of it, it was going to be me," said Rober, who spent nine years with NASA.

Consumers in Taiwan will only be able to use 4G services from 2019 as the government will shut down 3G services by the end of the year, according to a Sina news report on Monday, citing local Taiwan media reports. From a report: Although the vast majority of the population in Taiwan have shifted to 4G networks, there are still around 200,000 consumers using 3G. This has prompted local carriers to roll out incentives and promotions to get 3G users to shift onto the latest 4G plans. Taiwan's latest move to shut down 3G networks follows its earlier decision to remove all 2G networks on July 1, 2017, as local regulators and telecom operators continue to actively push for the development of 4G network coverage. As of March this year, the number of 4G users has already exceeded the population in Taiwan, said the report. The number of 3G users has declined to some 228,000 people in mid-November from 5.5 million in 2017.

An anonymous reader shares a report: According to the yearly report published by Stockholm-based phone number-identification service Truecaller, spam calls grew by 300 percent year-over-year in 2018. The report also found that telecom operators themselves are much to blame. Between January and October of this year, Truecaller said, users worldwide received about 17.7 billion spam calls. That's up from some 5.5 billion spam calls they received last year.

One of the most interesting takeaways from the report is a sharp surge in spam calls users received in Brazil this year, making it the most spammed country in the world. According to Truecaller, an average user in Brazil received over 37 spam calls in a month, up from some 20 spam calls during the same period last year. According to the report, telecom operators (at 32 percent) remained the biggest spammers in Brazil. The report also acknowledged the general election as an event that drove up spam calls in the country. As in Brazil, Indians were bombarded by telecom operators (a whopping 91 percent of all spam calls came from them) and service providers trying to sell them expensive plans and other offerings.

Spam calls received by users in the U.S. were down from 20.7 calls in a month to 16.9, while users in the U.K. saw a drop in their monthly dose of spam calls from 9.2 to 8.9. [...] Truecaller also reported that scam calls subjecting victims to fraud attempts and money swindling are still a prevalent issue. One in every 10 American adults lost money from a phone scam, according to a yearly report the firm published in April this year.
