Snapchat said Wednesday it would no longer promote President Donald Trump's content in its Discover section, a move that brings the messaging company closer to Twitter's approach in the ongoing debate over political speech. From a report: The company said in a statement that it would not "amplify voices who incite racial violence." Snapchat's Discover section typically features content from news organizations, brands, celebrities and sometimes politicians. The president's account remains visible on the platform, and anyone can follow the account for updates. Snapchat's change will remove Trump from the Discover section. "We are not currently promoting the president's content on Snapchat's Discover platform," the company said. "We will not amplify voices who incite racial violence and injustice by giving them free promotion on Discover. Racial violence and injustice have no place in our society and we stand together with all who seek peace, love, equality, and justice in America."

Researchers from Stanford University have devised a way for hundreds of drones to use the bus or trams in an effort to redesign how packages are distributed in cities. Should such a solution ever scale, it could reduce delivery van congestion and energy usage while extending the distance a drone can travel to deliver a package. From a report: There's a reason most delivery drones we've seen thus far are dropping packages off in the suburbs. Urban centers can be dynamic environments, full of unexpected obstacles, and drones are still not permitted to fly freely through cities. But researchers say using public transportation can increase a drone's range up to 360% beyond travel with flight alone.

"Our approach strives to minimize the maximum time to complete any delivery," the team writes in a paper published this week at the online 2020 IEEE International Conference on Robotics and Automation (ICRA). "By combining the strengths of both, we can achieve significant commercial benefits and social impact." This approach, which involves the drones hitching a ride on the outside of buses and trams, could help overcome the limited travel capacity of drones today. The popular DJI Mavic 2, for example, is able to fly a maximum distance of 18 kilometers, or about 11 miles round trip.

Remove China Apps, the viral Android app for flagging software made in China, has been removed from Google's Play Store. From a report: Before its demise, the app had reached the coveted number-one free download spot on the Play Store. The app was removed for violating Google's "Deceptive Behavior Policy," which states that apps cannot incentivize users to disable or remove other applications. Though Remove China Apps did not remove apps automatically, it did prompt users to do so. It had been downloaded more than 5 million times before its removal. Google is notoriously bad at policing its own Play Store, so the swift removal here is something of an outlier. The app's quick rise to fame made waves, especially in its home market of India, which likely led to a faster-than-usual investigation on Google's part.

Microsoft is starting to roll out its new Edge browser through Windows Update. The new Chromium-based version of Edge launched in January, but Windows users had to specifically download it. From a report: A Microsoft support article notes that it's now available on Windows Update, meaning it will soon arrive on the more than 1 billion Windows 10 devices in use. It appears that Edge will be automatically installed through Windows Update on Windows 10 version 1803 and higher. That covers the vast majority of versions of Windows 10 that are currently supported, meaning it should start showing up in Windows Update for everyone soon. As always, this is a gradual rollout, so you might not see it immediately on Windows Update just yet.

China's Huawei acted to cover up its relationship with a firm that had tried to sell prohibited U.S. computer gear to Iran, after Reuters in 2013 reported deep links between the firm and the telecom-equipment giant's chief financial officer, newly obtained internal Huawei documents show. From the report: Huawei has long described the firm -- Skycom Tech -- as a separate local business partner in Iran. Now, documents obtained by Reuters show how the Chinese tech titan effectively controlled Skycom. The documents, reported here for the first time, are part of a trove of internal Huawei and Skycom Iran-related business records -- including memos, letters and contractual agreements -- that Reuters has reviewed. One document described how Huawei scrambled in early 2013 to try to "separate" itself from Skycom out of concern over trade sanctions on Tehran. To that end, this and other documents show, Huawei took a series of actions -- including changing the managers of Skycom, shutting down Skycom's Tehran office and forming another business in Iran to take over tens of millions of dollars worth of Skycom contracts.

The revelations in the new documents could buttress a high-profile criminal case being pursued by U.S. authorities against Huawei and its chief financial officer, Meng Wanzhou, who is also the daughter of Huawei's founder. The United States has been trying to get Meng extradited from Canada, where she was arrested in December 2018. A Canadian judge last week allowed the case to continue, rejecting defense arguments that the U.S. charges against Meng do not constitute crimes in Canada. A U.S. indictment alleges that Huawei and Meng participated in a fraudulent scheme to obtain prohibited U.S. goods and technology for Huawei's Iran-based business via Skycom, and move money out of Iran by deceiving a major bank. The indictment alleges that Skycom was an "unofficial subsidiary" of Huawei, not a local partner.

If you're a free Zoom user, and waiting for the company to roll out end-to-end encryption for better protection of your calls, you're out of luck. From a report: Free calls won't be encrypted, and law enforcement will be able to access your information in case of 'misuse' of the platform. Zoom CEO Eric Yuan today said that the video conferencing app's upcoming end-to-end encryption feature will be available to only paid users.

An anonymous reader quotes a report from Ars Technica: In January, my coworker received a peculiar email. The message, which she forwarded to me, was from a handful of corporate Walmart employees calling themselves the "Concerned Home Office Associates." (Walmart's headquarters in Bentonville, Arkansas, is often referred to as the Home Office.) While it's not unusual for journalists to receive anonymous tips, they don't usually come with their own slickly produced videos. The employees said they were "past their breaking point" with Everseen, a small artificial intelligence firm based in Cork, Ireland, whose technology Walmart began using in 2017. Walmart uses Everseen in thousands of stores to prevent shoplifting at registers and self-checkout kiosks. But the workers claimed it misidentified innocuous behavior as theft and often failed to stop actual instances of stealing.

They told WIRED they were dismayed that their employer -- one of the largest retailers in the world -- was relying on AI they believed was flawed. One worker said that the technology was sometimes even referred to internally as "NeverSeen" because of its frequent mistakes. WIRED granted the employees anonymity because they are not authorized to speak to the press. The workers said they had been upset about Walmart's use of Everseen for years and claimed colleagues had raised concerns about the technology to managers but were rebuked. They decided to speak to the press, they said, after a June 2019 Business Insider article reported Walmart's partnership with Everseen publicly for the first time. The story described how Everseen uses AI to analyze footage from surveillance cameras installed in the ceiling and can detect issues in real time, such as when a customer places an item in their bag without scanning it. When the system spots something, it automatically alerts store associates. A video from the Concerned Home Office Associates "purports to show Everseen's technology failing to flag items not being scanned in three different Walmart stores," adds the report. "Set to cheery elevator music, it begins with a person using self-checkout to buy two jumbo packages of Reese's White Peanut Butter Cups. Because the packages are stacked on top of each other, only one is scanned, but both are successfully placed in the bagging area without issue."

"The same person then grabs two gallons of milk by their handles and moves them across the scanner with one hand. Only one is rung up, but both are put in the bagging area. They then put their own cell phone on top of the machine, and an alert pops up saying they need to wait for assistance -- a false positive."

Following the rioting and looting from the death of George Floyd, Apple has a message for those who power on a stolen iPhone: "This device has been disabled and is being tracked. Local authorities will be alerted." Forbes reports: Apple CEO Tim Cook sent a message to his employees as those protests escalated, saying that "there is a pain deeply etched in the soul of our nation and in the hearts of millions. To stand together, we must stand up for one another, and recognize the fear, hurt, and outrage rightly provoked by the senseless killing of George Floyd and a much longer history of racism." Cook went on to say that "at Apple, our mission has and always will be to create technology that empowers people to change the world for the better. We've always drawn strength from our diversity, welcomed people from every walk of life to our stores around the world, and strived to build an Apple that is inclusive of everyone."

These words were being digested as the tech giant made the decision to close the majority of its U.S. stores for the safety of those staff and its customers, stores that had only just reopened after the COVID-19 shutdown. Apple has unsurprisingly become a favored target of looters, given the likely spoils on offer, and the decision was taken to remove stock from shop floors and shutter locations. It has long been known that Apple operates some form of proximity software that disables a device when it is taken illegally from a store. Until now, though, little had been seen of that technology in action. Well, thanks to social media, we can now see the message that greets a looter powering up their new device: "This device has been disabled and is being tracked," it says. "Local authorities will be alerted."

Google was sued on Tuesday in a proposed class action accusing the internet search company of illegally invading the privacy of millions of users by pervasively tracking their internet use through browsers set in "private" mode. Reuters reports: The lawsuit seeks at least $5 billion, accusing the Alphabet unit of collecting information about what people view online and where they do their browsing, despite using what Google calls Incognito mode. The complaint said Google surreptitiously collects data through Google Analytics, Google Ad Manager and other applications and website plug-ins, including smartphone apps, regardless of whether users click on Google-supported ads. This helps the Mountain View, California-based company learn details about users' friends, hobbies, favorite foods, shopping habits, and even the "most intimate and potentially embarrassing things" they search for online, the complaint said.

Google "cannot continue to engage in the covert and unauthorized data collection from virtually every American with a computer or phone," the complaint said. The complaint said the proposed class likely includes "millions" of Google users who since June 1, 2016 browsed the internet in "private" mode. It seeks damages per user of $5,000 or three times actual damages, whichever is greater, for violations of federal wiretapping and California privacy laws.

MojoKid writes: AI and Machine Learning performance benchmarks have been well explored in the data center, but are fairly new and unestablished for edge devices like smartphones. While AI implementations on phones are typically limited to inferencing tasks like speech-to-text transcription and camera image optimization, there are real-world neural network models employed on mobile devices and accelerated by their dedicated processing engines. A deep dive look at HotHardware of three popular AI benchmarking apps for Android shows that not all platforms are created equal, but also that performance results can vary wildly, depending on the app used for benchmarking.

Generally speaking, it all hinges on what neural networks (NNs) the benchmarks are testing and what precision is being tested and weighted. Most mobile apps that currently employ some level of AI make use of INT8 (quantized). While INT8 offers less precision than FP16 (Floating Point), it's also more power-efficient and offers enough precision for most consumer applications. Typically, Qualcomm Snapdragon 865 powered devices offer the best INT8 performance, while Huawei's Kirin 990 in the P40 Pro 5G offers superior FP16 performance. Since INT8 precision for NN processing is more common in today's mobile apps, it could be said that Qualcomm has the upper hand, but the landscape in this area is ever-evolving to be sure.

Instagram users are flooding the platform with black squares in support of black victims of police violence as part of a Blackout Tuesday protest. CNBC reports: As of 11:45 a.m. ET, more than 14.6 million Instagram posts used the hashtag #BlackoutTuesday. Searches for "blackout tuesday image" and "blackout image" surged 400% Tuesday morning, according to Google Trends. The idea of an online movement was announced last week, when music executives Jamila Thomas and Brianna Agyemang called on members of the music industry to pause business on Tuesday and take a stand against racism.

"We will not continue to conduct business as usual without regard for Black lives," the founders wrote. Platforms, such as Apple Music, Spotify and YouTube Music, joined the movement and are using their apps to promote black artists. Additionally, media company ViacomCBS, which owns MTV, Comedy Central, Nickelodeon, Paramount Pictures, Pop, VH1, TV Land, among others, also joined this call to action. On Monday, the company's networks all went off the air for eight minutes and 46 seconds, the length of time that an officer in Minneapolis pressed his knee on Floyd's neck. The movement has since spread to brands, organizations and individuals, who are using Instagram to post only a black square Tuesday to show a virtual moment of silence. Others are choosing to continue posting, but will only amplify voices of the black community.

An anonymous reader quotes a report from The New York Times: President Trump's crackdown on social media companies faced a new legal challenge on Tuesday, as a technology policy organization claimed in a lawsuit that he violated the companies' right to free speech with his executive order aimed at curtailing their legal protections. The nonprofit Center for Democracy and Technology says in the suit that Mr. Trump's attempt to unwind a federal law that grants social media companies discretion over the content they allow on their platforms was retaliatory and would have a chilling effect on the companies.

The lawsuit -- filed in U.S. District Court for the District of Columbia -- is indicative of the pushback that the president is likely to face as he escalates his fight with social media companies, which he has accused of bias against conservative voices. It asks the court to invalidate the executive order. [...] "President Trump -- by publicly attacking Twitter and issuing the order -- sought to chill future online speech by other speakers," its filing said. The center added, "The order clouds the legal landscape in which the hosts of third-party content operate and puts them all on notice that content moderation decisions with which the government disagrees could produce penalties and retributive actions, including stripping them of Section 230's protections."

The U.S. investigation targets nine countries, plus the European Union, that have adopted or are considering new taxes that would hit American companies like Google and Amazon. From a report: The Trump administration said on Tuesday that it would open an investigation into taxes on digital commerce that have been adopted or proposed in nine countries and the European Union, escalating a global battle that will affect where big American tech companies like Facebook and Amazon pay taxes. The administration's move could ultimately lead to American tariffs on imports from Brazil, Britain, India and a host of other countries, heightening the chances of another global trade dispute that results in retaliatory taxes on U.S. goods.

The investigation, which will be conducted by the United States Trade Representative, could also complicate global negotiations that have been underway for more than a year and are aimed at reaching a multinational consensus on how to tax internet commerce that crosses borders. At issue are efforts spreading across Europe and beyond to impose so-called digital services taxes on economic activity generated online. Those taxes deviate from many traditional international tax regimes by affecting revenues earned by a company where they are generated -- regardless of whether the company has a physical presence there. For example, India imposed a 2 percent tax in April on online sales of goods and services to people in India by large foreign firms. The European Union has revived its push for a similar tax as a way to help fund response measures to the coronavirus.

In a call with Facebook employees, who have protested the inaction on Mr. Trump's messages, Mr. Zuckerberg said his decision was "pretty thorough." From a report: Mark Zuckerberg, Facebook's chief executive, on Tuesday stood firmly behind his decision to not do anything about President Trump's inflammatory posts on the social network, saying that he had made a "tough decision" but that it "was pretty thorough." In a question-and-answer session with employees conducted over video chat software, Mr. Zuckerberg sought to justify his position on Mr. Trump's messages, which has led to fierce internal dissent. The meeting, which had been scheduled for Thursday, was moved up to Tuesday after hundreds of employees protested the inaction by staging a virtual "walkout" of sorts on Monday. Facebook's principles and policies around free speech "show that the right action where we are right now is to leave this up," Mr. Zuckerberg said on the call, the audio of which was heard by The New York Times. He added that though he knew many people would be upset with the company, a review of its policies backed up his decision. "I knew that I would have to separate out my personal opinion," he said. "Knowing that when we made this decision we made, it was going to lead to a lot of people upset inside the company, and the media criticism we were going to get."

Services like Google Translate support only 100 languages, give or take. What about the thousands of other languages -- spoken by people just as vulnerable to this crisis? From a report: If we want to avoid a pandemic spreading to all the humans in the world, this information also has to reach all the humans of the world -- and that means translating Covid PSAs into as many languages as possible, in ways that are accurate and culturally appropriate. It's easy to overlook how important language is for health if you're on the English-speaking internet, where "is this headache actually something to worry about?" is only a quick Wikipedia article or WebMD search away. For over half of the world's population, people can't expect to Google their symptoms, nor even necessarily get a pamphlet from their doctor explaining their diagnosis, because it's not available in a language they can understand.

[...] In a pandemic, the challenge isn't just translating one or a handful of primary languages in a single region -- it's on a scale of perhaps thousands of languages, at least 1,000 to 2,000 of the 7,000-plus languages that exist in the world today, according to the pooled estimates of the experts I spoke with, all of whom emphasized that this number was very uncertain but definitely the largest number they'd ever faced at once. Machine translation might be able to help in some circumstances, but it needs to be approached with caution. [...] That's not to say that machine translation isn't helpful for some tasks, where getting the gist quickly is more important than the nuanced translations humans excel at, such as quickly sorting and triaging requests for help as they come in or keeping an eye on whether a new misconception is bubbling up. But humans need to be kept in the loop, and both human and machine language expertise needs to be invested in during calmer times so that it can be used effectively in a crisis.

The bigger issue with machine translation is that it's not even an option for many of the languages involved. Translators Without Borders is translating Covid information into 89 languages, responding to specific requests of on-the-ground organizations, and 25 of them (about a third) aren't in Google Translate at all. Machine translation disproportionately works for languages with lots of resources, with things like news sites and dictionaries that can be used as training data. Sometimes, like with French and Spanish, the well-resourced languages of former colonial powers also work as lingua francas for translation purposes. In other cases, there's a mismatch between what's easy to translate by machine versus what's useful to TWB: The group has been fielding lots of requests for Covid info in Kanuri, Dari, and Tigrinya, none of which are in Google Translate, but hasn't seen any for Dutch or Hebrew (which are in Google Translate but don't need TWB's help -- they have national governments already producing their own materials). Google Translate supports 109 languages, Bing Translate has 71, and even Wikipedia exists in only 309 languages -- figures that pale in comparison to the 500-plus languages on the list from the Endangered Languages Project, all human-created resources.

HBO Max, AT&T's big bet on the future of streaming, will be excused from AT&T's mobile data caps, while competing services like Netflix and Disney Plus will use up your data. From a report: That's the follow-up from a Vergecast conversation with Tony Goncalves, the AT&T executive in charge of HBO Max. Asked whether HBO Max would hit the cap, Goncalves said his team "had the conversation" but didn't have the answer. AT&T later confirmed to The Verge that HBO Max will be excused from the company's traditional data caps and the soft data caps on unlimited plans. According to an AT&T executive familiar with the matter, HBO Max is using AT&T's "sponsored data" system, which technically allows any company to pay to excuse its services from data caps. But since AT&T owns HBO Max, it's just paying itself: the data fee shows up on the HBO Max books as an expense and on the AT&T Mobility books as revenue. For AT&T as a whole, it zeroes out. Compare that to a competitor like Netflix, which could theoretically pay AT&T for sponsored data, but it would be a pure cost.

Hackers who obtained personal data on users of Canadian cryptocurrency exchange Coinsquare say they plan to use the information to perform so-called SIM swapping attacks, according to one of the hackers. Motherboard: The news shows hackers' continued interest in trying to leverage security issues with telecom-based forms of authentication. In a SIM swapping attack, a hacker takes control of a target's phone number, which then gives them the ability to request password resets for some websites or a victim's two-factor authentication code. Often, SIM swappers will use these techniques to steal cryptocurrency. The breach also signals the continued risk of insider access, with Coinsquare telling Motherboard a former employee was responsible for stealing the data. "The original intent was to sell it [the data] but we figured we would make more money by SIM swapping the accounts," a pseudonymous hacker who provided the Coinsquare data to Motherboard said in an online chat.

The US Department of Defense is woefully behind on its plan to upgrade its IT infrastructure to support the newer IPv6 protocol, according to a government report published on Monday. From a report: This current effort is the third time the DOD attempts to upgrade its infrastructure to support IPv6 over in the past 17 years. The first two attempts took place in 2003 and 2010, respectively. The 2003 effort was abandoned with the DOD citing security risks and a lack of personnel trained in IPv6, while the second attempt was also abandoned, similarly on the grounds that IPv6 was not yet secure enough for the DOD's sensitive networks.

On Monday, the Government Accountability Office (GAO), the auditing agency of the US government, said that the DOD's third attempt isn't doing any better either. GAO officials said the DOD failed to follow four basic requirements that were set out by the White House Office of Management and Budget (OMB) in 2006. The four requirements were part of an OMB guideline sent to all federal agencies detailing the proper procedure for upgrading networks from IPv4 to IPv6. "For its current [third] initiative, DOD has not completed three of four longstanding OMB requirements," GAO auditors said in a report published on Monday.

Social media has become a central battleground for the protests across the U.S., with tech platforms amplifying tensions while also providing a real-time chronicle of the riots and police responses that might not have otherwise gained widespread attention. From a report: A lone video of the violent arrest that led to the death of George Floyd posted last Monday on Facebook by a bystander, Darnella Frazier, has been shared by 52,000 people there and found its way to Twitter, Instagram and other social platforms, widening awareness of the episode. Since then, those outlets have been a tool to spread dissent and anger by those upset at Mr. Floyd's death and those disturbed by the sometimes violent actions of both protesters and police in cities across the country. Social media played a critical role in galvanizing the protesters through the quickly shared video around Mr. Floyd's arrest, said Alex Stamos, director of Stanford University's Internet Observatory. "It nationalizes local issues like this," he said, adding that "maybe 20 years ago this might have only been covered at the local press."

The unrest also has fueled an online battle over how they are viewed, said Nathaniel Persily, a Stanford law professor and co-director of the California university's Cyber Policy Center, said the riots also have turned into an online battle of opposing viewpoints. "There is a fight on social media as to how to portray the events on the ground," he said. In some cases, distortions are fanning the anger. One photo pairing widely shared last week purported to show Derek Chauvin, the police officer who knelt on Mr. Floyd's neck during the fatal arrest, having previously worn a red cap resembling those favored at President Trump's rallies but with the slogan "Make Whites Great Again." Twitter slapped a label saying "Manipulated media" on tweets containing the photos -- including one from the rapper Ice Cube that has been liked more than 148,000 times -- taking users to a post where it said several photos purporting to show Mr. Chauvin were of other people.

It's no secret that 5G networks drain battery. "To rectify that grim side effect, researchers at the University of Texas at Austin and the University of Lille in France have developed a new radio-frequency switch they say is 50 times more energy efficient than the current solid-state switches," reports Popular Mechanics. From the report: The solution is actually rooted right in the problem. Because smartphones are packed with switches that perform duties like hopping back and forth between different networks and spectrum frequencies (4G to LTE, to WiFi, to Bluetooth, etc.), batteries drain much faster. State-of-the-art radio-frequency switches are constantly running in the background on your iPhone or Android device, consuming not only battery life, but processing power. So when the limited number of 5G-enabled smartphones on the market are constantly bouncing back and forth between 4G and 5G communications, for instance, the problem is amplified.

"The switch we have developed can transmit an HDTV stream at a 100GHz frequency, and that is an achievement in broadband switch technology," lead researcher Deji Akinwande, a professor at the University of Texas at Austin, said in a prepared statement. And the premise is simple: the switches stay off most of the time. Unless the radio-frequency switches are actively helping the device jump between networks at that precise point in time, they stay off, preserving precious battery life for other processes.

To build it, the scientists used a nanomaterial called hexagonal boron nitride, a newcomer in the materials science field that comes from the same family as graphene, a honeycomb-lattice sheet of carbon atoms used in everything from bike tires to cleaning up radioactive waste. According to research in Semiconductors and Semimetals, hexagonal boron nitride is only as thick as a single layer of atoms and is the thinnest known insulator in the world, with a thickness of 0.33 nanometers (for comparison's sake, a human hair is about 100,000 nanometers thick). In this case, these scientists used a single layer of boron and nitrogen atoms in a honeycomb pattern. Then, they sandwiched the layers between a set of gold electrodes. The findings have been published in the journal Nature Electronics.
