An anonymous reader shares a report: Google is adding a personalised Facebook-style news feed to its homepage -- Google.com -- to show users content they may be interested in before they search. It will display news stories, features, videos and music chosen on the basis of previous searches by the same user. Users will also be able to click a "follow" button on search results to add topics of interest to their feed. One analyst said the move would help Google compete with rivals. "Google has a strong incentive to make search as useful as possible," said Mattia Littunen, a senior research analyst at Enders Analysis. "Facebook's news feed is one of its main rivals. It is competing with other ways of accessing content."

Apple, Google and Microsoft are sitting on a mountain of cash -- and most of it is stashed far away from the taxman. Those three tech behemoths held a total of $464 billion in cash at the end of last year, according to a Moody's report published this week. From a report: Apple alone had a stunning quarter-trillion dollars of cash thanks to years of gigantic profits and few major acquisitions. That's enough money to buy Netflix three times. It's also more cash than what's sitting on the balance sheet of every major industry except tech and health care. All told, non-financial U.S. companies studied by Moody's hoarded $1.84 trillion of cash at the end of last year. That's up 11% from 2015 and nearly two and a half times the 2008 level. Roughly $1.3 trillion -- 70% of the total -- is being held overseas, where the money isn't subject to U.S. taxes. Apple, Google owner Alphabet, Microsoft, Cisco, and Oracle hold 88% of their cash overseas. Moody's said the tower of money stashed abroad reflects the "negative tax consequences of permanently repatriating money to the U.S."

An anonymous reader shares a report:Elon Musk just tweeted that his Boring Company tunnel project has just received "verbal [government] approval" to build a hyperloop connecting New York City, Philadelphia, Baltimore, and Washington, DC. While we work to verify his claim, Musk is continuing to tweet more details about the project. The hyperloop, an ultrafast method of travel first developed by Musk in 2013, would only take 29 minutes to travel between New York City and DC, he claims. And it would feature "up to a dozen or more" access points via elevator in each city.

Reader Baron_Yam shares a PCWorld report: No Windows 10 Creators Update for you, Microsoft says -- at least, not if you happen to be the unlucky owner of certain older Atom-based Windows devices, and other aging models in the future. After stories arose of failed attempts to upgrade such hardware to the Creators Update, Microsoft confirmed late Wednesday that any hardware device that falls out of the manufacturer's support cycle may be ineligible for future Windows 10 updates. In the case of the four "Clover Trail" processors (part of the Cloverview platform) that have fallen into Intel's End of Interactive Support phase, they will be ineligible for the Windows 10 Creators Update, Microsoft confirmed. Instead, they'll simply be offered the Windows 10 Anniversary Update, plus security updates through January, 2023, the end of the original Windows 8.1 support period. The problem, however, is that Microsoft's language opens up the possibility that any unsupported hardware device could be excluded from future Windows 10 updates. "Recognizing that a combination of hardware, driver and firmware support is required to have a good Windows 10 experience, we updated our support lifecycle policy to align with the hardware support period for a given device," Microsoft said in a statement. "If a hardware partner stops supporting a given device or one of its key components and stops providing driver updates, firmware updates, or fixes, it may mean that device will not be able to properly run a future Windows 10 feature update." The reader adds, it's not a case of "feature updates are not recommended and may not work", it's a case of "we will block feature updates to your device".

Intel has axed the division that worked on health wearables, including fitness trackers, CNBC is reporting citing a source. From the report: The company has been slowly de-emphasizing its own line of wearables for the past several years, and has not mentioned wearables on its earnings calls since 2014. In November, TechCrunch reported that the company was planning to take a step back from the business after its acquisition of the Basis fitness watch didn't pan out as expected. Intel denied at the time that it was stepping back. But a source told CNBC that the chip maker in fact let go about 80 percent of the Basis group in November. Many of the people were given the opportunity to relocate to other parts of the business. About two weeks ago, Intel completely eliminated the group, this person said. The company's New Technologies Group, which looks at cutting-edge business areas, is now focusing on augmented reality, another source told CNBC.

The United States has ended a four-month ban on passengers carrying laptops onboard US-bound flights from certain airports in the Middle East and North Africa, bringing to an end one of the controversial travel restrictions imposed by President Donald Trump's administration. From a report: Riyadh's King Khalid international airport was the last of 10 airports to be exempted from the ban, the US department of homeland security (DHS) confirmed in a tweet late on Wednesday local time. Middle East carriers have blamed Trump's travel restrictions, which include banning citizens of some Muslim-majority countries from visiting the United States, for a downturn in demand on US routes. In March, the United States banned large electronics in cabins on flights from 10 airports in the Middle East and North Africa over concerns that explosives could be concealed in the devices taken onboard aircraft. The ban has been lifted on the nine airlines affected -- Emirates, Etihad Airways, Qatar Airways, Turkish Airlines, Saudi Arabian Airlines, Royal Jordanian , Kuwait Airways, EgyptAir and Royal Air Maroc -- which are the only carriers to fly direct to the US from the region. A ban on citizens of six Muslim-majority countries -- Iran, Libya, Somalia, Sudan, Syria, and Yemen, -- remains in place, though has been limited after several US court hearings challenged the restrictions.

An anonymous reader quotes a report from Reuters: A U.S. House panel on Wednesday approved a sweeping proposal by voice vote to allow automakers to deploy up to 100,000 self-driving vehicles without meeting existing auto safety standards and bar states from imposing driverless car rules. Representative Robert Latta, a Republican who heads the Energy and Commerce Committee subcommittee overseeing consumer protection, said he would continue to consider changes before the full committee votes on the measure, expected next week. The full U.S. House of Representatives will not take up the bill until it reconvenes in September after the summer recess. The measure, which would be the first significant federal legislation aimed at speeding self-driving cars to market, would require automakers to submit safety assessment reports to U.S. regulators, but would not require pre-market approval of advanced vehicle technologies. Automakers would have to show self-driving cars "function as intended and contain fail safe features" to get exemptions from safety standards but the Transportation Department could not "condition deployment or testing of highly automated vehicles on review of safety assessment certifications," the draft measure unveiled late Monday said.

randomErr shares a report from CTV News: The first child in the world to undergo a double hand transplant is now able to write, feed and dress himself, doctors said Tuesday, declaring the ground-breaking operation a success after 18 months. The report in The Lancet Child & Adolescent Health provides the first official medical update on 10-year old Zion Harvey, who underwent surgery to replace both hands in July 2015. Harvey had his hands and feet amputated at the age of two, following a sepsis infection. He also had a kidney transplant. Harvey was already receiving drugs to suppress any immune reaction to his kidney, which was a key factor in his selection for the 10-plus hour hand transplant surgery.

SpaceX has largely confirmed the rumors that the company is no longer planning to send an uncrewed version of its Dragon spacecraft to Mars in 2020, or later. Ars Technica reports: The company had planned to use the propulsive landing capabilities on the Dragon 2 spacecraft -- originally developed for the commercial crew variant to land on Earth -- for Mars landings in 2018 or 2020. Previously, it had signed an agreement with NASA to use some of its expertise for such a mission and access its deep-space communications network. On Tuesday, however, during a House science subcommittee hearing concerning future NASA planetary science missions, Florida Representative Bill Posey asked what the agency was doing to support privately developed planetary science programs. Jim Green, who directs NASA's planetary science division, mentioned several plans about the Moon and asteroids, but he conspicuously did not mention Red Dragon. After this hearing, SpaceX spokesman John Taylor didn't return a response to questions from Ars about the future of Red Dragon. Then, during a speech Wednesday at the International Space Station Research and Development Conference, Musk confirmed that the company is no longer working to land Dragon propulsively for commercial crew. "Yeah, that was a tough decision," Musk acknowledged Wednesday with a sigh. "The reason we decided not to pursue that heavily is that it would have taken a tremendous amount of effort to qualify that for safety for crew transport," Musk explained Wednesday. "There was a time when I thought the Dragon approach to landing on Mars, where you've got a base heat shield and side mounted thrusters, would be the right way to land on Mars. But now I'm pretty confident that is not the right way." Musk added that his company has come up with a "far better" approach to landing on Mars that will be incorporated into the next iteration of the company's proposed Mars transportation hardware.

theodp writes: In A Son's Race to Give His Dying Father Artificial Immortality (Warning: may be paywalled; alternate source), James Vlahos recounts his efforts to turn the story of his father's life -- as told by his 80-year-old Dad in his final months after being diagnosed with stage IV lung cancer -- into what Vlahos calls "a Dadbot -- a chatbot that emulates not a children's toy but the very real man who is my father." Given the limits of tech at the time (2016) and his own inexperience as a programmer, Vlahos recognized that the bot would never be more than a shadow of his real dad, but hoped to get the bot to communicate in his father's distinctive manner and convey at least some sense of his personality. Of the first time he demoed the bot for his parents, Vlahos writes: "Emboldened, I bring up something that has preoccupied me for months. 'This is a leading question, but answer it honestly,' I say, fumbling for words. 'Does it give you any comfort, or perhaps none -- the idea that whenever it is that you shed this mortal coil, that there is something that can help tell your stories and knows your history?' My dad looks off. When he answers, he sounds wearier than he did moments before. 'I know all of this shit,' he says, dismissing the compendium of facts stored in the Dadbot with a little wave. But he does take comfort in knowing that the Dadbot will share them with others. 'My family, particularly. And the grandkids, who won't know any of this stuff.' He's got seven of them, including my sons, Jonah and Zeke, all of whom call him Papou, the Greek term for grandfather. 'So this is great,' my dad says. 'I very much appreciate it.'"

An anonymous reader quotes a report from Quartz: A team of computer scientists at the University of Washington have used artificial intelligence to render visually convincing videos of Barack Obama saying things he's said before, but in a totally new context. In a paper published this month, the researchers explained their methodology: Using a neural network trained on 17 hours of footage of the former U.S. president's weekly addresses, they were able to generate mouth shapes from arbitrary audio clips of Obama's voice. The shapes were then textured to photorealistic quality and overlaid onto Obama's face in a different "target" video. Finally, the researchers retimed the target video to move Obama's body naturally to the rhythm of the new audio track. In their paper, the researchers pointed to several practical applications of being able to generate high quality video from audio, including helping hearing-impaired people lip-read audio during a phone call or creating realistic digital characters in the film and gaming industries. But the more disturbing consequence of such a technology is its potential to proliferate video-based fake news. Though the researchers used only real audio for the study, they were able to skip and reorder Obama's sentences seamlessly and even use audio from an Obama impersonator to achieve near-perfect results. The rapid advancement of voice-synthesis software also provides easy, off-the-shelf solutions for compelling, falsified audio. You can view the demo here: "Synthesizing Obama: Learning Lib Sync from Audio"

HBO is leaving no stones unturned in keeping Game of Thrones' piracy under control. The company is monitoring various popular torrent swarms and sending thousands of warnings targeted at internet subscribers whose connections are used to share the season 7 premiere of the popular TV series, reports TorrentFreak: Soon after the first episode of the new season appeared online Sunday evening, the company's anti-piracy partner IP Echelon started sending warnings targeted at torrenting pirates. The warnings in question include the IP-addresses of alleged BitTorrent users and ask the associated ISPs to alert their subscribers, in order to prevent further infringements. "We have information leading us to believe that the IP address xx.xxx.xxx.xx was used to download or share Game of Thrones without authorization," the notification begins. "HBO owns the copyright or exclusive rights to Game of Thrones, and the unauthorized download or distribution constitutes copyright infringement. Downloading unauthorized or unknown content is also a security risk for computers, devices, and networks." Under US copyright law, ISPs are not obligated to forward these emails, which are sent as a DMCA notification. However, many do as a courtesy to the affected rightsholders. The warnings are not targeted at a single swarm but cover a wide variety of torrents. TorrentFreak has already seen takedown notices for the following files, but it's likely that many more are being tracked.

randomErr writes from a report via Business Insider (alternate source): Ethereum, the rival to bitcoin, has been on a tear. Its founders said the latest trend in the cryptocurrency space may not be as good for the cryptocurrency as some might think. Ethereum is up 1,700% over the last year, and that spike has occurred in tandem with the growth of the hottest new trend in fundraising: initial coin offerings. Approximately $1.2 billion has been raised by the new cryptocurrency-based capital raising method this year, according to Autonomous Next, a financial technology analytics service. It is a trend that has sparked excitement across Wall Street. But the cofounder of the company behind the cryptocurrency, Charles Hoskinson, told Bloomberg that initial coin offerings may not benefit Ethereum. "People say ICOs are great for ethereum because, look at the price, but it's a ticking time-bomb," said Hoskinson. "There's an over-tokenization of things as companies are issuing tokens when the same tasks can be achieved with existing blockchains. People are blinded by fast and easy money."

After 3 months, Samsung announced that the voice capabilities of its digital assistant are now rolling out to U.S. Galaxy S8 and S8+ owners. Now, if you happen to own a Galaxy S8 or S8+, the physical Bixby button on the lefthand side of your phone will be able to actually do something somewhat useful. The Verge reports: Bixby's voice capabilities have been available in the US as part of an opt-in beta test, and Samsung says that feedback has led to faster response times, improved comprehension of varied phrasing around the same question, better hands-free operation, and more. Over 100,000 users of the flagship devices have enrolled in the early access program and issued over 4 million voice commands. Also, Samsung says Bixby can now read aloud your latest SMS messages and emails -- if you use its stock apps on the Galaxy S8. Bixby can be activated with a push of the dedicated Bixby button located on the side of the Galaxy S8 and S8+, or by saying "hi Bixby." Like Siri and Google Assistant, Bixby can handle alarms, send texts, and so on, but its real power lies in the ability to access granular phone settings or -- in supported apps -- automatically move through several menu screens to perform commands that Google Assistant simply can't do. Samsung says that deep learning should allow Bixby to improve over time as it begins to recognize users' preferences and ways of speaking. Here's a video showing some of the voice commands Bixby can respond to.

An anonymous reader quotes a report from Bleeping Computer: An unknown hacker has used a vulnerability in an Ethereum wallet client to steal over 153,000 Ether, worth over $30 million dollars. The hack was possible due to a flaw in the Parity Ethereum client. The vulnerability allowed the hacker to exfiltrate funds from multi-sig wallets created with Parity clients 1.5 and later. Parity 1.5 was released on January 19, 2017. The attack took place around 19:00-20:00 UTC and was immediately spotted by Parity, a company founded by Gavin Wood, Ethereum's founder. The company issued a security alert on its blog. The Ether stolen from Parity multi-sig accounts was transferred into this Ethereum wallet, currently holding 153,017.021336727 Ether. Because Parity spotted the attack in time, a group named "The White Hat Group" used the same vulnerability to drain the rest of Ether stored in other Parity wallets that have not yet been stolen by the hacker. This money now resides in this Ethereum wallet. According to messages posted on Reddit and in a Gitter chat, The White Hat Group appears to be formed of security researchers and members of the Ethereum Project that have taken it into their own hands to secure funds in vulnerable wallets. Based on a message the group posted online, they plan to return the funds they took. Their wallet currently holds 377,116.819319439311671493 Ether, which is over $76 million.

schwit1 shares a report from CNN: In the sometimes hostile waters of the Persian Gulf looms the U.S. Navy's first -- in fact, the world's first -- active laser weapon. The LaWS, an acronym for Laser Weapons System, is not science fiction. It is not experimental. It is deployed on board the USS Ponce amphibious transport ship, ready to be fired at targets today and every day by Capt. Christopher Wells and his crew. It costs "about a dollar a shot" to fire, said Lt. Cale Hughes, laser weapons system officer. LaWS begins with an advantage no other weapon ever invented comes even close to matching. It moves, by definition, at the speed of light. For comparison, that is 50,000 times the speed of an incoming ICBM. For the test, the USS Ponce crew launched the target -- a drone aircraft, a weapon in increasing use by Iran, North Korea, China, Russia and other adversaries. In an instant, the drone's wing lit up, heated to a temperature of thousands of degrees, lethally damaging the aircraft and sending it hurtling down to the sea. "It operates in an invisible part of the electromagnetic spectrum so you don't see the beam, it doesn't make any sound, it's completely silent and it's incredibly effective at what it does," said Hughes.

New submitter sarbonn writes: Facebook is testing whether or not it can start charging for stories by placing a paywall that appears after ten stories have been viewed from one of its media sources. An interesting takeaway is that Facebook would like to do this by avoiding the mandatory 30 percent cut that Apple and Google get from their stores by going around their app stores. This is being targeted for around October. The news comes from Campbell Brown, who heads Facebook's new partnerships business. "We are in early talks with several news publishers about how we might better support subscription business models on Facebook. As part of the Facebook Journalism Project, we are taking the time to work closely together with our partners and understand their needs," Brown told TechCrunch in a statement via a spokesperson.

An anonymous reader quotes a report from The Verge: In a recent report, Russia-24, a state-owned news channel, suggests that fidget spinners are being used by Russian opposition parties in order to recruit young people. As reported by The New York Times, the reporters in Russia-24's initial story say, "It is a mystery why it has become so popular in Russia right now. Who is promoting this to the masses so actively?" The video segment says the toys were being distributed at a rally for opposition leader Alexei Navalny and in online ads that direct viewers to YouTube channels that promote opposition politicians. The reporters said that while the toy's popularity was declining in the West, fidget spinners are more popular than ever in Russia. "As you can see here there is only writing in English, on the other side there is not a word in Russian," says one of the show's anchors during the report, presenting a new spinner in its packaging to the camera. According to Newsweek, a second report on Russia-24 also aired on July 12th, directly saying fidget spinners were an "object for zombifying" and a form of "hypnosis." The program featured a report from psychologist Svetlana Filatova, claiming that the spinners could help dexterity in children but otherwise "dulls" people's minds. The reports spurred Russia's consumer protection agency, Rospotrebnadzor, into action, saying on Tuesday they would launch an investigation into the toy.

An anonymous reader shares a report: According to a confidential document obtained by Motherboard, wireless communications lobby group CTIA took issue with an in-depth report by the Department of Homeland Security on mobile device security, including flaws with the SS7 network. In a white paper sent to members of Congress and the Department of Homeland Security, CTIA, a telecom lobbying group that represents Verizon, AT&T, and other wireless carriers, argued that "Congress and the Administration should reject the [DHS] Report's call for greater regulation" while downplaying "theoretical" security vulnerabilities in a mobile data network that hackers may be able to use to monitor phones across the globe, according to the confidential document obtained by Motherboard. However, experts strongly disagree about the threat these vulnerabilities pose, saying the flaws should be taken seriously before criminals exploit them. SS7, a network and protocol often used to route messages when a user is roaming outside their provider's coverage, is exploited by criminals and surveillance companies to track targets, intercept phone calls or sweep up text messages. In some cases, criminals have used SS7 attacks to obtain bank account two-factor authentication tokens, and last year, California Rep. Ted Lieu said that, for hackers, "the applications for this vulnerability are seemingly limitless."

Earlier this week, Comcast filed its comments in favor of the FCC's plan to eliminate the 2015 net neutrality rules. While much of the document was devoted to arguments we've heard before -- Comcast believes the current rules are anti-competitive and hurt investment, but generally supports the principles of net neutrality -- one statement stood out. The Verge adds: Buried in the 161-page document was this quirky assertion (emphasis ours): "At the same time, the Commission also should bear in mind that a more flexible approach to prioritization may be warranted and may be beneficial to the public... And paid prioritization may have other compelling applications in telemedicine. Likewise, for autonomous vehicles that may require instantaneous data transmission, black letter prohibitions on paid prioritization may actually stifle innovation instead of encouraging it. In other words, Comcast is arguing for paid prioritization and internet fast lanes to enable self-driving cars to communicate better with other vehicles and their surrounding environment, thus making them a safer and more efficient mode of transportation. The only problem is that autonomous and connected cars don't use wireless broadband to communicate. When cars talk with each other, they do it by exchanging data wirelessly over an unlicensed spectrum called the Dedicated Short Range Communications (DSRC) band, using technology similar to Wi-Fi. The FCC has set aside spectrum in the 5.9GHz band specifically for this purpose, and it is only meant to be used for vehicle-to-everything (V2X) applications. That includes vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), and vehicle-to-pedestrian (V2P) -- so cars talking to other cars, to traffic signals, to the phone in your pocket... you name it. Soon enough, all cars sold in the US will be required to include V2V technology for safety purposes, if the Department of Transportationâ(TM)s new rule goes into effect.

The European Union's top court is set to decide whether the bloc's "right to be forgotten" policy stretches beyond Europe's borders, a test of how far national laws can -- or should -- stretch when regulating cyberspace. From a report: The case stems from France, where the highest administrative court on Wednesday asked the EU's Court of Justice to weigh in on a dispute between Alphabet's Google and France's privacy regulator over how broadly to apply the right (Editor's note: the link could be paywalled; alternative source), which allows EU residents to ask search engines to remove some links from searches for their own names. At issue: Can France force Google to apply it not just to searches in Europe, but anywhere in the world? The case will set a precedent for how far EU regulators can go in enforcing the bloc's strict new privacy law. It will also help define Europe's position on clashes between governments over how to regulate everything that happens on the internet -- from political debate to online commerce. France's regulator says enforcement of some fundamental rights -- like personal privacy -- is too easily circumvented on the borderless internet, and so must be implemented everywhere. Google argues that allowing any one country to apply its rules globally risks upsetting international law and, when it comes to content, creates a global censorship race among autocrats.

Software companies are seeking to exploit the current artificial intelligence craze by "AI washing" -- exaggerating the role of AI in their products, according to a new report by Gartner, the research firm. From a report: Gartner, which tracks commercial manias through a tool it calls the Hype Cycle, compares what is currently going on in AI with a prior surge in environmental over-statement -- "greenwashing, in which companies exaggerate the environmental-friendliness of their products or practices for business benefit." The bottom line: More than 1,000 vendors say their products employ AI, but many are "applying the AI label a little too indiscriminately," Gartner says in its report. Kriti Sharma, who runs the AI team at Sage, tells Axios that a lot of companies are seeking to solve problems using AI that would be better done by humans. And what is often called AI "is just automation that you are doing," she said.

An anonymous reader tips us a story: Just two years ago, Microsoft cast its Wilsonville factory as the harbinger of a new era in American technology manufacturing. The tech giant stamped, "Manufactured in Portland, OR, USA" on each Surface Hub it made there. It invited The New York Times and Fast Company magazine to tour the plant in 2015, then hired more than 100 people to make the enormous, $22,000 touch-screen computer. But last week Microsoft summoned its Wilsonville employees to an early-morning meeting and announced it will close the factory and lay off 124 employees -- nearly everyone at the site -- plus dozens of contract workers. Panos Panay, the vice president in charge of the Surface product group, traveled from corporate headquarters in Redmond, Washington, to tell the staff that Microsoft was moving production to the same place it makes all other Surface products. Though workers present say he didn't disclose the location, Microsoft has previously said it makes its other Surface computers in China. The company hasn't explained, in public or to its Wilsonville employees, why it gave up on domestic manufacturing so quickly and didn't respond to repeated inquiries for comment. But the only thing surprising about Microsoft's decision is that it tried to make its computers in the U.S. in the first place.

An anonymous reader shares a report: India's massive diesel-guzzling railway network is getting serious about its experiments with solar. On July 14, Indian Railways rolled out its first train with rooftop solar panels that power the lights, fans, and information display systems inside passenger coaches. Although the train will still be pulled by a diesel-powered locomotive, a set of 16 solar panels atop each coach will replace the diesel generators that typically power these appliances. The railways estimate that a train with six solar-powered coaches could save around 21,000 litres (5,547 gallons) of diesel every year, worth around $108,000. In 2014, Indian Railways consumed 2.6 billion litres of diesel, accounting for around 70% to the network's total fuel bill of $4.4 billion. The first of these trains will be pressed into service on the suburban railway network of New Delhi, one of the world's most polluted cities, before two dozen more coaches are fitted with similar rooftop solar systems. Retrofitting each coach with these system, including an inverter to optimise power generation and battery for storing surplus power, costs around $14,000.
