One of the prototypes Alphabet's Sidewalk Labs is working on for its planned neighborhood on Toronto's waterfront is a hexagonal paving system. "The slabs are porous and heated, which may keep snow and ice at bay without salting," reports Engadget. "They're easy to replace, and include LED lights that can, for instance, help direct traffic flow during construction or mark street closures." From the report: Sidewalk will also demonstrate what it's calling a Building Raincoat, an awning it says will help protect sidewalks from wind, rain, sun and snow to make outdoor space usable throughout the year. It attaches to the sides of buildings and is fixed to ground anchors. It's made from a durable, lightweight and transparent plastic called ETFE (Ethylene Tetrafluoroethylene).

In addition, Sidewalk will have a number of art installations at the public event, which "use lighting, projection mapping, mud and other techniques to reflect on relationships between humans and animals in public space, and the broader connection of ecology and urbanism." Some of the works will be projected onto the awning. Along with the prototypes, Sidewalk will discuss some of its broader ideas about how to make its neighborhood livable and accessible, in part through affordable housing and its transit system.

Microsoft has built a "Clinical Trials Bot" that does just as the name implies: suggests links to trials that best match the patients' needs. The bot "lets patients and doctors search for studies related to a disease and then answer a succession of text questions," reports Bloomberg. "Drugmakers can also use it to find test subjects." From the report: Microsoft won't release the bot as its own product. Instead, the software giant is talking to pharmaceutical companies that it hopes will use the bot to find trial participants, while pitching it to other partners that could turn the technology into a tool for patients, said Hadas Bitran, group manager of Microsoft Healthcare Israel. Bitran declined to name possible partners because no deals have been agreed yet. The project is part of a larger Microsoft health-care bot initiative that's helped partners build automatic chat programs for things like triaging patients and answering questions about insurance benefits. The clinical trials bot was accepted as part of the U.S. White House Presidential Innovation Fellows program and Bitran showed it on Thursday at a closed door event at the White House. She will demonstrate the tech publicly on Friday during a session at the U.S. Census Bureau.

The technology uses a form of artificial intelligence called machine reading to ingest the selection criteria for each clinical trial. It uses this data to decide which questions to ask patients and how to match their answers to suitable trials. Here's how it works for patients: They type in a search, such as "trials for a 52-year old California female with breast cancer." The bot responds with questions such as whether the patient had chemotherapy for metastatic disease -- a cancer that has spread -- and how far the patient can travel. It offers five choices that describe the patient's current health and ability to be active and care for herself. As the patient selects from the multiple-choice answers, the software generates the next question and refines the list of available trials.

Josh Constine, writing for TechCrunch: Facebook has changed its story after initially trying to downplay how it targeted teens with its Research program that a TechCrunch investigation revealed was paying them gift cards to monitor all their mobile app usage and browser traffic. "Less than 5 percent of the people who chose to participate in this market research program were teens," a Facebook spokesperson told TechCrunch and many other news outlets in a damage control effort 7 hours after we published our report on January 29th. At the time, Facebook claimed that it had removed its Research app from iOS. The next morning we learned that wasn't true, as Apple had already forcibly blocked the Facebook Research app for violating its Enterprise Certificate program that supposed to reserved for companies distributing internal apps to employees.

It turns out that wasn't the only time Facebook deceived the public in its response regarding the Research VPN scandal. TechCrunch has obtained Facebook's unpublished February 21st response to questions about the Research program in a letter from Senator Mark Warner. [...] In the response from Facebook's VP of US public policy Kevin Martin, the company admits that "At the time we ended the Facebook Research App on Apple's iOS platform, less than 5 percent of the people sharing data with us through this program were teens. Analysis shows that number is about 18 percent when you look at the complete lifetime of the program, and also add people who had become inactive and uninstalled the app."

Biting your tongue at yet another questionable article shared in your message group? Add artificial-intelligence fact-checker Meiyu, she will jump in with 'False.' From a report: The artificial-intelligence bot will interject in real time when she detects posts about the news, pointing out factual errors and alternative interpretations. The technology, created by Taiwanese developers, is a step ahead of most fact-checking apps, including versions offered in Brazil and Indonesia, which don't jump into conversations. Other popular fact-checkers, such as Snopes in the U.S., are public databases that users consult for reviews of news items. Meiyu quickly became hot in Taiwan, which had just gone through divisive local elections and is rife with rumors of China's interference in social media. The bot now has more than 110,000 users on the Japanese messaging app Line, which covers about 90% of the mobile-messaging market in Taiwan.

Ebay may be paving the way to auction off some of its businesses. The e-commerce company said Friday that it is initiating a strategic review of its assets, including ticket sales site StubHub and the Classifieds Group, after facing pressure from activist investors to spin off or sell these properties. From a report: Ebay is also adding two directors to its board, including Jesse Cohn of Elliott Management, a hedge fund that disclosed a 4% stake in the company in January and began agitating for change. Devin Wenig, Ebay's president and CEO, said in a statement Friday that these moves are the result of "two months" of dialogue between the company and investors. "The bottom line is that we all share common ground: We see tremendous opportunity ahead and want to see Ebay's full potential realized over the long-term," Wenig said. Last month, eBay announced a restructuring that would bring various regional marketplace units under one global leadership team.

Amazon's physical Dash buttons are no more. The e-commerce giant has stopped selling its tap-to-order Dash buttons as of February 28th. From a report: If you still proudly use a Dash button (or a few dozen), don't worry: Amazon plans to continue supporting new orders through existing Dash buttons so long as the public keeps using them. So what killed the Dash button's future? Well, by Amazon's telling, the device was a victim of its own success, since it helped nudge forward the concept of the connected home to what it is today. Daniel Rausch, an Amazon vice president who helped grow the Dash program from its start, said that back in early 2015, when the Dash button first came out, there were far fewer options for connected home gadgets. Amazon workers were trying to figure out a way "to make shopping disappear" for grocery list items like paper towels and printer ink and whatever else is pretty not-fun to go out and buy, Rausch said.

The mammoth University of California (UC) system announced this week that it will stop paying to subscribe to journals published by Elsevier, the world's largest scientific publisher. From a report: Talks to renew a collective contract broke down, the university said, because Elsevier refused to strike a package deal that would provide a break on subscription fees and make all articles published by UC authors immediately free for readers worldwide. The stand by UC, which followed eight months of negotiations, could have significant impacts on scientific communication and the direction of the so-called open access movement, in the United States and beyond. The 10-campus system accounts for nearly 10 percent of all U.S. publishing output and is among the first American institutions, and by far the largest, to boycott Elsevier over costs. Many administrators and librarians at American universities and elsewhere have complained about what they view as excessively high journal subscription fees charged by commercial publishers.

An anonymous reader quotes a report from TechCrunch: Twitter today confirmed it's developing a new "Hide Tweet" feature, which it says will give users another option to protect their conversations. The option, spotted in Twitter's code, is available from a list of moderation choices that appear when you click the "Share" button on a tweet -- a button whose icon has also been given a refresh, it seems. Like it sounds, "Hide Tweet" functions as an alternative to muting or blocking a user, while still offering some control over a conversation. Related to this, an option to "View Hidden Tweets" was also found to be in the works. This allows a user to unhide those tweets that were previously hidden by the original poster.

Immediately, there were concerns that an option like this would allow users to silence their critics -- not just for themselves, as is possible today with muting and blocking -- but for anyone reading through a stream of Twitter Replies. Imagine, for example, if a controversial politician began to hide tweets they didn't like or those that contradicted an outrageous claim with a fact check, people said. It also requires the user to click to view the Replies that were hidden, which some users may not know to do and others may not bother to do. They may then miss out on an important point in the conversation, or a critical fact check. On the flip side, putting the original poster back in control of which Replies are visible may allow people to feel more comfortable with sharing on Twitter, which could impact user growth -- a number Twitter struggles with today. And it could encourage people to debate things with less vitriol, knowing that their nastier tweets could get hidden view. The "Hide Tweet" feature was first discovered by Jane Manchun Wong.

An anonymous reader quotes a report from ScienceDaily: Humans and other mammals are limited to seeing a range of wavelengths of light called visible light, which includes the wavelengths of the rainbow. But infrared radiation, which has a longer wavelength, is all around us. People, animals and objects emit infrared light as they give off heat, and objects can also reflect infrared light. A multidisciplinary group of scientists led by Xue and Jin Bao at the University of Science and Technology of China as well as Gang Han at the University of Massachusetts Medical School, developed the nanotechnology to work with the eye's existing structures.

In this study, the scientists made nanoparticles that can anchor tightly to photoreceptor cells and act as tiny infrared light transducers. When infrared light hits the retina, the nanoparticles capture the longer infrared wavelengths and emit shorter wavelengths within the visible light range. The nearby rod or cone then absorbs the shorter wavelength and sends a normal signal to the brain, as if visible light had hit the retina. "In our experiment, nanoparticles absorbed infrared light around 980 nm in wavelength and converted it into light peaked at 535 nm, which made the infrared light appear as the color green," said one of the researchers. The researchers tested the nanoparticles in mice, which, like humans, cannot see infrared naturally. Mice that received the injections showed unconscious physical signs that they were detecting infrared light, such as their pupils constricting, while mice injected with only the buffer solution didn't respond to infrared light. The study was published in the journal Cell.

itwbennett writes: If you're running Elasticsearch 1.4.2 and lower, you should make sure your patches are up to date. That's because researchers from Cisco's Talos group have "detected an increase in attacks targeting unsecured Elasticsearch clusters." At least six different groups are responsible for the increase, each deploying different malware, but regardless of the method, the potential impact of a breach is huge because Elasticsearch is designed to work with big data and companies use it to process sensitive data. "Given the size and sensitivity of the data sets these clusters contain, the impact of a breach of this nature could be severe," the Talos researchers warned.

An anonymous reader quotes a report from The New York Times: Some of the world's biggest internet messaging companies are hoping to succeed where cryptocurrency start-ups have failed by introducing mainstream consumers to the alternative world of digital coins. The internet outfits, including Facebook, Telegram and Signal, are planning to roll out new cryptocurrencies over the next year that are meant to allow users to send money to contacts on their messaging systems, like a Venmo or PayPal that can move across international borders. The most anticipated but secretive project is underway at Facebook. The company is working on a coin that users of WhatsApp, which Facebook owns, could send to friends and family instantly.

The Facebook project is far enough along that the social networking giant has held conversations with cryptocurrency exchanges about selling the Facebook coin to consumers. Telegram, which has an estimated 300 million users worldwide, is also working on a digital coin. Signal, an encrypted messaging service that is popular among technologists and privacy advocates, has its own coin in the works. And so do the biggest messaging applications in South Korea and Japan, Kakao and Line. The messaging companies have a reach that dwarfs the backers of earlier cryptocurrencies. Facebook and Telegram can make the digital wallets used for cryptocurrencies available, in an instant, to hundreds of millions of users. Most of them appear to be working on digital coins that could exist on a decentralized network of computers, independent to some degree of the companies that created them. Facebook reportedly has more than 50 engineers working on their cryptocurrency. Their project is being run by former president of PayPal, David Marcus, and started last year after Telegram raised $1.7 billion to fund its cryptocurrency project. "The five people who have been briefed on the Facebook team's work said the company's most immediate product was likely to be a coin that would be pegged to the value of traditional currencies," NYT reports, citing a report from Bloomberg. "A digital token with a stable value would not be attractive to speculators -- the main audience for cryptocurrencies so far -- but it would allow consumers to hold it and pay for things without worrying about the value of the coin rising and falling." The coin should come out in the first half of the year.

Tesla CEO Elon Musk said in a call with reporters Thursday that the company will only sell its vehicles online. As a result, the electric carmaker will close most of its stores over the "next few months." The Verge reports: Tesla will keep some of its retail locations open, which the company described as "a small number of stores in high-traffic locations remaining as galleries, showcases and Tesla information centers." The decision to shift away from brick-and-mortar retail is necessary if the company is to remain financially sustainable, Tesla said. The company's finances have stabilized somewhat in recent months, but Tesla still operates on very tight margins. Tesla said in a blog post: "You can now buy a Tesla in North America via your phone in about 1 minute, and that capability will soon be extended worldwide. We are also making it much easier to try out and return a Tesla, so that a test drive prior to purchase isn't needed. You can now return a car within 7 days or 1,000 miles for a full refund. Quite literally, you could buy a Tesla, drive several hundred miles for a weekend road trip with friends and then return it for free."

The company announced the move at the same time it said it will finally begin to sell its long-promised $35,000 Model 3.

In a call with reporters Thursday, Tesla CEO Elon Musk said the company is finally launching the long-promised standard Model 3 with a base price of $35,000. "The automaker is now making several new versions of the Model 3 available with a shorter range and new interior options," reports Electrek. From the report: Today, Tesla sent an email to its retail stores the details of the announcement of the new options being available to order in the U.S. today and available as soon as next month. All the details are expected to become available in the next hour, but here's what we know so far: Customers are now able to order the $35,000 Model 3 with a standard interior and standard battery pack enabling 130mph top speed and 5.6s 0-60s acceleration. Tesla is also making a new "Partial Premium Interior" with better seats than the standard interior available with a different "standard range plus" battery pack for a $2,000 premium. The Model 3 Standard Range Plus results in 240 miles of range, a top speed of 140mph, 0-60mph acceleration of just 5.3 seconds. Tesla says that deliveries are starting within the next 2 to 4 weeks depending on the configuration in the U.S. In Europe, Musk said it will be available to order within the "next 3 to 6 months." Slashdot reader Rei provides additional details: The new unveiling introduced a whole slew of variants, including (price, range, top speed, 0-60, premium):

SR: $35K, 220 miles, 130mph, 5.6 seconds, non-PUP
SR+: $37K, 240 miles, 140mph, 5.3 seconds, partial-PUP
MR: $40K, 264 miles, 140mph, 5.2 seconds, PUP
LR: $43K, 325 miles, 140mph, 5.0 seconds, PUP
AWD: $47K, 310 miles, 145mph, 4.5 seconds, PUP
P: $48K, 310 miles, 162mph, 3.2 seconds, PUP

Pricing, ranges, and features have by and large significantly surpassed initial promises. For example, the Long Range (LR) variant was supposed to be a $9K premium over SR, with the Premium Upgrades Package another $5k, but now PUP is included in LR and the price difference is only $8K. Range and performance specs have been upgraded not just on new vehicles, but will also be upgraded on existing vehicles, where applicable, via software update. The price for Autopilot has dropped from $5K to $3K, and some features once planned to be premium-only -- including the glass roof and auto dimming, power folding, heated side mirrors -- are now standard. The Model S and X product line has also been modified, with higher performance at the top end and lower prices at the bottom.

To achieve cost savings, in addition to production optimizations and the recent layoffs, Tesla announced an unexpected strategy: they're closing most of their stores. Sales will only be conducted online. Instead of test drives, cars can be returned within 7 days or 1,000 miles at no charge. "Quite literally, you could buy a Tesla, drive several hundred miles for a weekend road trip with friends and then return it for free," Tesla said in their blog post.

The Polestar 2 is the first all-electric car from Volvo, and the first car to feature Google's new native version of Android Auto. Billed as a competitor to Tesla's Model 3, "the Polestar 2 should be able to travel up to 275 miles (about 443 kilometers) on a single charge thanks to a 78kWh battery that makes up the entire floor of the car," reports The Verge. "It will be quick, too; Polestar says there's 300kW (about 408 horsepower) to play with, spread across dual electric motors. That all-wheel drive power should help the car get from 0 to 60 miles per hour in under 5 seconds." From the report: All this will eventually cost about 39,900 euros, or about $45,000, at the cheapest. Polestar will sell versions of the car that cost as much as 59,900 euros, or about $68,000. But none of that will happen until the second year of production. The version available when the car launches later this year will cost $63,000, and Polestar will make only that "launch edition" car for the first 12 months. Pre-orders are open now, and production begins next year in China (where Volvo's Chinese parent company Geely is headquartered). Polestar's launching the car with in an ambitious slate of markets, too: China, the United States, Canada, the United Kingdom, Germany, the Netherlands, Norway, Sweden, and Belgium.
[...]
[T]he Polestar 2's interior looks more fully developed and coherent than the one in the Polestar 1, to my eyes at least. The centerpiece is an 11-inch portrait oriented touchscreen where the company's Android-based infotainment system lives. Car companies have built infotainment systems on Android in the past, but they essentially had to fork the open source operating system and build their own solution on top. What's more, Google wasn't involved in those efforts. This meant the cars would wind up with outdated versions of Google's operating system, which complicated upgrades and security. [...] A big benefit to this embedded approach is customers will have instant access to Android Auto-approved apps like Google Maps, or Play Music, or Google Assistant without needing to use their smartphones. Another is that it will have access to the car's functions, meaning it can control climate settings, or send you maintenance alerts. This native version of Android will also be updatable, meaning Polestar and Google can push over-the-air software updates to improve the car's functions long after it's sold.

Mozilla wants to make it easier for startups, researchers, and hobbyists to build voice-enabled apps, services, and devices. From a report: Toward that end, it's today releasing the latest version of Common Voice, its open source collection of transcribed voice data that now comprises over 1,400 hours of voice samples from 42,000 contributors across 18 languages, including English, French, German, Dutch, Hakha-Chin, Esperanto, Farsi, Basque, Spanish, Mandarin Chinese, Welsh, and Kabyle. It's one of the largest multi-language dataset of its kind, Mozilla claims -- substantially larger than the Common Voice corpus it made publicly available eight months ago, which contained 500 hours (400,000 recordings) from 20,000 volunteers in English -- and the corpus will soon grow larger still. The organization says that data collection efforts in 70 languages are actively underway via the Common Voice website and mobile apps.

An anonymous reader quotes a report from Ars Technica: The Windows 10 Insider Preview Slow Ring -- the beta track that's meant to receive only those builds that are free from any known serious problems -- hasn't received an update for months. While the fast ring is currently testing previews of the April 2019 release, codenamed 19H1, and the even-faster skip-ahead ring is testing previews not of the October 2019 release, 19H2, but of the April 2020 release, 20H1, the Slow Ring is yet to receive a single 19H1 build. This has prompted some concern among insiders that perhaps the ring has been forgotten about, and it has even caused a few complaints from companies that are using the Windows Insider for Business program to validate new Windows releases before their launch. Without Slow Ring builds to test, there's nothing to validate, meaning that they'll have to delay deployment of 19H1 once it ships.

Microsoft's Dona Sarkar, chief of the Windows Insider program, explained yesterday what the problem is, and in many ways it's a throwback to Windows' past, before the days of DEP and ASLR and PatchGuard and all the other measures Microsoft has implemented to harden Windows against malicious software: the build is crashing when some unspecified common anti-cheat software is used. Sarkar's tweet says that the software causes a GSOD, for Green Screen of Death; the traditional and disappointingly familiar Blue Screen of Death, denoting that Windows has suffered a fatal error, is colored green for preview releases so they can be distinguished at a glance from crashes of stable builds. Fast ring builds have the same GSOD issue, and indeed, it has been listed on their known issues list for many months. Sarkar says that the fix must come from the third-party company that developed the anti-cheat software. In an update, Ars Technica's Peter Bright says Microsoft has pushed a build to the Slow Ring, number 18342.8, but the GSOD issue remains. "To avoid crashing machines, the build won't be offered to any system that has the offending anti-cheat software installed," Bright writes. "It's not clear why this approach could not have been used months ago."

U.S. companies installed more robots last year than ever before, as cheaper and more flexible machines put them within reach of businesses of all sizes and in more corners of the economy beyond their traditional foothold in car plants. From a report: Shipments hit 28,478, nearly 16 percent more than in 2017, according to data seen by Reuters that was set for release on Thursday by the Association for Advancing Automation, an industry group based in Ann Arbor, Michigan. Shipments increased in every sector the group tracks, except automotive, where carmakers cut back after finishing a major round of tooling up for new truck models.

The U.S. Department of Transportation and the Federal Aviation Administration have issued new rules designed to protect air passengers from the potential dangers of lithium ion batteries. From a report: The new Transportation Department rules come after Congress last year directed the agency to adopt the new rules. The new restriction doesn't apply to passengers or crew bringing electronics aboard aircraft. "This rule will strengthen safety for the traveling public by addressing the unique challenges lithium batteries pose in transportation," US Secretary of Transportation Elaine L. Chao said in a statement. In the past couple of years, the use of lithium-ion batteries has been linked to fires and spewing smoke in a slew of products, including Samsung's now-canceled Galaxy Note 7, hoverboards and Boeing's 787 Dreamliner.

YouTube said today it will disable the ability for viewers to leave comments on most videos featuring minors, as it tries to contain the damage from a scandal involving child predators leaving coded sexual comments on the site. From a report: YouTube said in a blog post Thursday that over the past week it had already disabled comments from "tens of millions of videos" that could be subject to predatory behavior. Now, it will expand that to suspend comments on virtually all videos featuring young minors, as well as videos featuring older kids that "could be at risk of attracting predatory behavior." In a tweet, YouTube CEO Susan Wojcicki linked to the update and explained the change: "Recently, there have been some deeply concerning incidents regarding child safety on YouTube. Nothing is more important to us than ensuring the safety of young people on the platform."

Even San Francisco's tech chops can't save it from relying on computers that belong in a museum. From a report: The only place in San Francisco still pricing real estate like it's the 1980s is the city assessor's office. Its property tax system dates back to the dawn of the floppy disk. City employees appraising the market work with software that runs on a dead programming language and can't be used with a mouse. Assessors are prone to make mistakes when using the vintage software because it can't display all the basic information for a given property on one screen. The staffers have to open and exit several menus to input stuff as simple as addresses. To put it mildly, the setup "doesn't reflect business needs now," says the city's assessor, Carmen Chu.

San Francisco rarely conjures images of creaky, decades-old technology, but that's what's running a key swath of its government, as well as those of cities across the U.S. Politicians can often score relatively easy wins with constituents by borrowing money to pay for new roads and bridges, but the digital equivalents of such infrastructure projects generally don't draw the same enthusiasm. "Modernizing technology is not a top issue that typically comes to mind when you talk to taxpayers and constituents on the street," Chu says. It took her office almost four years to secure $36 million for updated assessors' hardware and software that can, among other things, give priority to cases in which delays may prove costly. The design requirements are due to be finalized this summer.
