Bill Gates has donated over $4 million to Code.org, while Mark Cuban has donated over $500,000. But long-time Slashdot reader theodp writes that they're now doing even more: As it strives to "teach your children at home while school is closed", tech-backed Code.org's efforts to engage students and their parents have included encouraging kids to email app pitches for Shark Tank investor Mark Cuban (AP CSP teachers were contacted and asked to make students aware of this "once in a lifetime opportunity") and join two-way Zoom meetings with Cuban and other celebrities like Bill Gates.
Gates called the health crisis "a bit like war, with all of humanity fighting the virus," and added that the internet was helping to "reduce the pain a little bit," according to Geekwire's report.

"Calling it a 'crazy time,' Gates said he is safe with his family at home and he's consuming endless information about what's happening with the pandemic in the United States and around the world...

"He said it will be interesting to see whether some students learn better, going at their own pace, digging online for more information, reaching out to friends who are good at particular subjects."

This week, tech pundit Robert Cringely described how a chance conversation with China-based entrepreneur Anina led to a friend with a garment factory "now making fully certified N-95 respirators with no clear distribution plan." Late on a Sunday night with the tech world in shut-down, how long would it take for me to find someone looking for up to five million N-95 masks? It took 10 minutes.

I reached out to Salesforce.com CEO Marc Benioff and to Mark Cuban from the Dallas Mavericks and Shark Tank... Mark Cuban put me in touch with ProjectN95, a just-created national clearinghouse for urgently needed medical equipment... It's important to realize what a miracle we accomplished. Normally there are lots of middlemen in Chinese distribution, but in this case, there were none, which meant maximal speed and minimal price. The goods were U.S. FDA certified, too, and the certification could be verified...

We are tech people attempting to function during a pandemic, but what really counted here were personal relationships. Anina knows and trusts the factory owner. Anina and I have known each other for 15 years and I've known Marc Benioff and Mark Cuban even longer. We spend billions as a culture trying to build digital versions of such webs of trust, but sometimes it is better to do it the old fashion way.

An anonymous reader quotes a report from Ars Technica: So-called "acoustic metamaterials" are specifically designed to control and manipulate sound waves, usually for the purpose of dampening or transmitting sound. But such an acoustic device can only perform the function for which it was created, such as dampening outgoing sound in a submarine, for example. That same device could not be repurposed to communicate with another passing vessel should the situation aboard the submarine require it; a different acoustic device must be used, one developed expressly for that purpose. Now a team of scientists from the University of Southern California have developed an acoustic metamaterial that can switch between different uses by applying carefully tailored magnetic fields, according to a new paper in the journal Research. The structure of these new metamaterials was inspired by the unusual structure of shark skin. They can be used to mimic the function of switches, logic gates, or diodes, raising the possibility of a sound "computer."

CNN has a story about a Chinese prototype helicopter that looks like a UFO. Slashdot reader ClickOnThis shares the report: China has been unveiling a lot of new weaponry lately, but one of their latest reveals looks really, well, out of this world. Called the "Super Great White Shark" by Chinese media, the aircraft conjures up images of 1950s sci-fi movies more than 21st century technology. But China says the "armed helicopter" was designed for the "future digital information battlefield." State-tabloid the Global Times published an image gallery of the aircraft, calling it a fusion of modern, proven helicopter designs -- such as the American AH-64 Apache and CH-53 Sea Stallion as well as the Russian Ka-52 and Mi-26 copters. It also has the blended-wing design employed by stealth aircraft, including the US B-2 bomber. [...] The prototype was displayed last week at the China Helicopter Exposition in Tianjin. It was a static display only. The aircraft is landbound -- at least for now.

Roomba robotic vacuum maker IRobot Corp. is suing rival SharkNinja for copying a device of theirs and selling it at "half the price." "Shark is not even shy about being a copycat," iRobot said in a lawsuit filed Tuesday in federal court in Boston, "claiming that the Shark IQ Robot offers the same iRobot technology at 'half the price of iRobot i7+'."Bloomberg reports: The company that unveiled the Roomba robotic vacuum in the early 2000s launched a product last year that takes house cleaning to a new level: It maps your home, schedules sweeps through each room, empties the dust bin itself and even knows where to resume cleaning after has returned to its base for a recharge. After being recognized by Time magazine for one of 2018's inventions of the year, IRobot Corp. says it's no accident that rival SharkNinja Operating LLC came out with a similar device a year later. [...] SharkNinja, a unit of closely held EP Midco LLC, on Friday filed a pre-emptive lawsuit in federal court in Delaware, asking the court to declare that the Shark IQ doesn't infringe six patents cited in iRobot's complaint, nor five others. IRobot had previously demanded that the Shark IQ be pulled off store shelves.

MojoKid writes: Gamer-targeted smartphones are beginning to pop up more often now, with devices like the Razer Phone 2, Xiaomi Black Shark, and the ASUS ROG Phone making waves in the market with performance enthusiasts. The latest release from ASUS, the ROG Phone II sports a specially binned chip from Qualcomm called the Snapdragon 855+. The higher performance SoC sports an octa-core CPU clocked at 2.96GHz, paired with an overclocked Adreno 640 GPU that can boost its performance up to 15 percent above spec. A generous 12GB of RAM, 1TB of storage and a 120Hz 6.59 FHD display trim out the rest of the ASUS ROG Phone II's specs. In addition, an enhanced on-board cooling system features a 3D vapor chamber, heat spreaders, and cooling pads that efficiently dissipate heat from inside the phone to the outside. It is designed to be above spec for the Snapdragon 855 chipset and necessary to keep 855+ stable during long gaming sessions. In benchmark testing, there's no question these system upgrades put up significantly better numbers than the average high-end Android phone on the market these days, such that the phone is about 10% faster than devices like Samsung's Galaxy Note 10 or the OnePlus 7 Pro. The ASUS ROG Phone II will be available later this month but pricing is still being determined.

Police have urged everyone to download a smartphone app they say has already saved several lives. What is it and how does it work? From a report: Kicked. Converged. Soccer. These three randomly chosen words saved Jess Tinsley and her friends after they got lost in a forest on a dark, wet night. They had planned a five-mile circular stroll through the 4,900 acre (2,000 hectare) woodland Hamsterley Forest, in County Durham, on Sunday evening, but after three hours they were hopelessly lost. "We were in a field and had no idea where we were," the 24-year-old care worker from Newton Aycliffe said. "It was absolutely horrendous. I was joking about it and trying to laugh because I knew if I didn't laugh I would cry."

At 22:30 BST they found a spot with phone signal and dialled 999. "One of the first things the call-handler told us to do was download the what3words app," Ms Tinsley said. "I had never heard of it." Within a minute of its download, the police said they knew where the group was and the soaked and freezing walkers were swiftly found by the Teesdale and Weardale Search and Mountain Rescue Team. "I have told everyone I know to download this app," Ms Tinsley said. "You never know when you are going to get lost and need it." What3words essentially points to a very specific location. Its developers divided the world into 57 trillion squares, each measuring 3m by 3m (10ft by 10ft) and each having a unique, randomly assigned three-word address. For example, the door of 10 Downing Street is slurs.this.shark, while the area across the road where the press congregate is stage.pushy.nuns.

dryriver writes: The line "sharks with fricking lasers" was once popular on Slashdot. It sounds like a joke, but a never-made James Bond movie co-written back in the day by Sean Connery was actually going to feature robotic sharks carrying stolen NATO nukes in order to attack New York. Bond was going to stop the sharks inside the New York sewer system, waterski out of the sewers, paraglide up to the Statue of Liberty's head, then fight a Bond villain inside said head, with the villain's "blood trickling out of the Statue of Liberty's eye like tears" at the end of the fight. All this was going to happen without the consent of Cubby Broccoli, the official producer of the Bond movies. Why did the movie never get made? The producers of competing Bond movies were fighting in court over who has what rights to the franchise and characters. In the end, "Bond fights robot sharks with nukes" was scrapped, and "Never Say Never Again," a remake of "Thunderball," was made instead. This featured stolen nukes as well, but unfortunately no robot sharks or other "Austin Powers" style silliness.

The Amazon panopticon may soon be getting a few new eyes. From a report: In February 2018, Amazon paid $1 billion to acquire Ring, the connected-camera doorbell company whose founder was once rejected on Shark Tank. Since then, Ring has been integrated with other Amazon services, allowing live feeds from its devices on Amazon Echo Shows and leading to new products such smart floodlights. Ring has also helped Amazon to flesh out its rather creepy Key service, where users with Ring doorbells (and other connected products) can choose to let people and deliveries into their homes remotely. Ring has also been building up its Neighbors app, which allows Ring users to share their camera footage with people who live nearby, allowing them to see if they believe any crimes have been committed nearby.

Ring has also forged partnerships with more than 50 police departments, leading to communities that are effectively surveilled by the police, through the camera company owned by the US's largest e-commerce company. Amazon is apparently not stopping there with its one-stop viewing. The company recently received trademarks, uncovered by Quartz, for multiple products that bear the Ring name, including Ring Beams, Ring Halo, and Ring Net. All three trademarks are listed as covering a range of uses, many matching what Ring products currently offer, including internet-connected security cameras, alarm systems, lighting, and cloud video storage.

Augmented reality is coming to Google Search, allowing you to "check out a pair of shoes in the 'real world' while you're shopping online or put an animated shark in your living room," reports The Verge. From the report: At I/O, Google offered a few different examples of how its AR search options might work. If you search for musculature, for instance, you can get a model of human muscles -- which you can either examine as an ordinary 3D object on your screen or overlay on a camera feed, letting you "see" the object in the real world. If you're looking at shopping results, you can preview a piece of clothing with your existing wardrobe.

3D AR objects will start showing up in search results later this year, and developers can add support for their own objects by adding "just a few lines of code." It's apparently already working with NASA, New Balance, Samsung, Target, Volvo, and other groups to add support for their 3D models.

An anonymous reader quotes a report from Motherboard: Now, emails obtained through a public records request provide insight into how facial recognition companies attempt to strike deals with local law enforcement as well as gain access to sensitive data on local residents. The emails show how a firm backed by Shark Tank judge, Dallas Mavericks owner, and billionaire entrepreneur Mark Cuban pushed a local police department to try and gain access to state driver's license photos to train its product. The emails also show the company asked the police department to vouch for it on a government grant application in exchange for receiving the technology for free.

"Chief, you seemed pretty keen on the use of facial recognition in stadiums. If you know of any place to start, please let me know," a 2016 email from Jacob Sniff, a co-founder of facial recognition startup Suspect Technologies, addressed to Michael Botieri, chief of the Plymouth Police Department in Massachusetts, reads. In the emails, Sniff repeatedly asked Botieri to deploy the technology in his district to help improve the product. Sniff mentioned plans for the technology to search through results for people of a particular gender or ethnicity, and deploy "emotion recognition."

"So you would aim to do this on all or most of the buildings you showed me in person? We would be fine on the privacy concerns for this?" Sniff wrote in a November 2017 email to the police department. "I do realize the technology could be perceived as controversial, though the stark reality is that it could save lives." "Ed, you mentioned that if we did the lobby idea in Boston, that they would go absolutely nuts and it would be a privacy disaster. Our discussion last week was that police departments are supposed to be welcoming and this would ultimately deter people from showing up," Sniff wrote in an April 2018 email chain including Ed Davis, former Boston Police Commissioner and who now runs a security consulting firm. [...] Sniff asked Chief Botieri to sign a letter helping Suspect Technologies receive a grant from the National Institute of Standards and Technology (NIST), according to a January 2017 email. Sniff offered to give the police department the facial recognition technology for free in exchange for signing the letter.

Scientists in Hong Kong, the Philippines and Guam have found that whale shark tourism in Tan-awan, Oslob, the Philippines, has led to degradation of the local coral reef ecosystem. They reported their findings in Environmental Management. From a report: Oslob, a small municipality on the south coast of Cebu, the Philippines, has become a domestic and international tourism hotspot since 2011, attracting over 300,000 visitors to the village of Tan-awan in 2015. The mass tourism phenomenon is fueled by the year-round presence of whale sharks along the local shallow reef. This unusual aggregation is maintained by the local tourism association feeding the whale sharks with up to 50 tons of shrimps annually.

In this study, scientists from the University of Hong Kong (HKU), the University of Guam, and the Large Marine Vertebrates Research Institute Philippines (LAMAVE) have demonstrated that whale shark tourism has had a detrimental effect on the local reef ecosystem off the coast of Tan-awan. They found that Tan-awan had higher macroalgae and lower coral density, as well as a less diverse coral community dominated by weedy corals and stress-tolerant corals, in comparison to a reference site further south of the coast.

[...] The researchers added that reef degradation in Tan-awan requires immediate attention, given that reef health underpins the ecosystem services afforded to the local communities, including the important tourism sector. As whale shark tourism is projected to grow continuously in the foreseeable future, the research team urges the need for local authorities to implement proper management strategies to mitigate the problems and risks associated with the rapid tourism development.

Mary Jo Foley, writing for ZDNet: Every tech vendor these days is quick to slap the AI label on products and services. Up until today, I thought Microsoft had done an admirable job in refraining from doing this with Windows. But the shark has been jumped as of March 7, the company's latest Windows Developer Day. Cue the eye rolls. Microsoft is telling developers that the next release of Windows 10, which we are still calling by its codename, "Redstone 4," will enable developers to "use AI to deliver more powerful and engaging experiences." Microsoft execs say there's now an AI platform in Windows 10 that enables developers to use "pre-trained machine learning in their apps on Windows 10 devices."

An anonymous reader writes: As climate change ushers in another year of extreme global temperatures -- a phenomenon President Trump seems a little confused about -- cities up and down the East Coast are facing record-breaking snowfall and subzero temperatures. But while city dwellers might be able to hide indoors and crank up the heat, some animals aren't so lucky. According to the Cape Cod-based Atlantic White Shark Conservancy, it's gotten so cold that sharks in the area have been washing up on the shore and essentially freezing to death. This week, the organization responded to three thresher sharks that likely suffered "cold shock" in the surrounding waters. Organisms suffer cold shock when they're exposed to extreme dips in temperature and can sometimes experience muscle spasms or cardiac arrest. Scientists believe the sharks swimming off the coast of Cape Cod -- where temperatures have dropped to 6 degrees -- suffered cold shock in the water, and then wound up getting stranded on the shore, where they likely suffocated. "If you've got cold air, that'll freeze their gills up very quickly," Greg Skomal, a marine scientist, told the New York Times. "Those gill filaments are very sensitive and it wouldn't take long for the shark to die."

An anonymous reader shares a report: Kevin O'Leary has invested hundreds of thousands of dollars in small businesses over the course of his tenure as a star and investor on ABC's "Shark Tank." But there is one business to which he refuses to fork over his hard-earned dollars: coffee shops. "Do I pay $2.50 for a coffee? Never, never, never do I do that," O'Leary tells CNBC Make It. "That is such a waste of money for something that costs 20 cents. I never buy a frape-latte-blah-blah-blah-woof-woof-woof for $2.50." Instead, he makes it at home. "I drink coffee, one cup every morning," he explains. "It costs about 18 cents to make it, and I invest the rest." That idea -- saving small sums and investing continually -- is central to O'Leary's personal finance advice. "The truth is, there is a lot of crap you don't need," he explains.

An anonymous reader shares an article: While Daymond John was building his clothing line FUBU, which would evolve into a $6 billion brand, the entrepreneur was living on the tips he made waiting tables at Red Lobster. "I was working at Red Lobster for five years as a waiter as I was running this business," the Shark Tank star said at the iConic conference in New York City on Wednesday. At first "it was 40 hours at Red Lobster and six hours at FUBU. Then it was 30 hours at Red Lobster and 20 hours at FUBU, because money started to come in." Even after FUBU started to take off, John continued waiting tables. He wouldn't do things any differently if he could, he told the audience on Wednesday: "Don't quit your day job. [...] Let's say I was making an average of $40,000 a year," he continued. "After five years, that's $200,000 of salary. I would have had to sell $1 million more worth of FUBU product to bring home the $200,000, but I didn't have to do that. I just had to sacrifice time."

On Tuesday, Apple made its debut into the world of original television programming with "Planet of the Apps," a reality show that brings app developers in a competition to try to get mentoring and assistance from hosts Jessica Alba, will.i.am, Gwyneth Paltrow and entrepreneur Gary Vaynerchuk. Contestants describe their proposals as they ride an escalator down onto a stage where the judges sit, and then fire questions at the app developer. The problem? Critics aren't pleased. An anonymous reader shares a Variety report: Apple's first offering, "Planet of the Apps," feels like something that was developed at a cocktail party, and not given much more rigorous thought or attention after the pitcher of mojitos was drained. It's not terrible, but essentially, it's a bland, tepid, barely competent knock-off of " Shark Tank." Apple made its name on game-changing innovations, but this show is decidedly not one of them. The program's one slick innovation is the escalator pitch. You read that right; I didn't mistype "elevator pitch." The show begins with an overly brief set-up segment, which doesn't spend much time explaining the rules of the show, and which also assumes that a viewer will know who host Zane Lowe is, though a reasonably large chunk of the audience won't. Soon enough, app developers step into a pitch room with a very long escalator in the middle of it. As the four judges listen (often with looks of glacial boredom on their faces), the aspiring creators have one minute of escalator time to tout the product they want funding for. After the app makers get to the bottom of the conveyance, the judges (or "advisors") vote yea or nay. As long as one judge has given the developers a green light, they can continue making their pitch.

An anonymous reader quotes a report from New Scientist: A female shark separated from her long-term mate has developed the ability to have babies on her own. Leonie the zebra shark (Stegostoma fasciatum) met her male partner at an aquarium in Townsville, Australia, in 1999. They had more than two dozen offspring together before he was moved to another tank in 2012. From then on, Leonie did not have any male contact. But in early 2016, she had three baby sharks. Intrigued, Christine Dudgeon at the University of Queensland in Brisbane, Australia, and her colleagues began fishing for answers. One possibility was that Leonie had been storing sperm from her ex and using it to fertilize her eggs. But genetic testing showed that the babies only carried DNA from their mum, indicating they had been conceived via asexual reproduction. Some vertebrate species have the ability to reproduce asexually even though they normally reproduce sexually. These include certain sharks, turkeys, Komodo dragons, snakes and rays. However, most reports have been in females who have never had male partners. In sharks, asexual reproduction can occur when a female's egg is fertilized by an adjacent cell known as a polar body, Dudgeon says. This also contains the female's genetic material, leading to "extreme inbreeding", she says. "It's not a strategy for surviving many generations because it reduces genetic diversity and adaptability." Nevertheless, it may be necessary at times when males are scarce. "It might be a holding-on mechanism," Dudgeon says. "Mum's genes get passed down from female to female until there are males available to mate with." It's possible that the switch from sexual to asexual reproduction is not that unusual; we just haven't known to look for it, Dudgeon says.

Long-time Slashdot reader v3rgEz writes: Documents recently declassified show one of the odder experimental weapons developed after World War II: Weaponized sharks. Guided by sharp electric shocks, the sharks were trained to deliver explosive payloads -- essentially turning them into living, breathing, remote-controlled torpedoes that could be put to use in the Pacific Theater.
Following years of research on "shark repellent," the Navy spent 13 years building a special head gear for sharks which sensed the shark's direction and tried to deliver shocks if the sharks strayed off-course. The journalist who tracked down details of "Project Headgear" published the recently-declassified information on MIT's journalism site Undark, noting that "The shark wasn't so much a 'torpedo' as a suicide bomber... "
