Eloking writes: Canadian Prime Minister Justin Trudeau's Twitter account lit up today with a message all too familiar to many indie devs: Mr. Trudeau has made a video game, and he'd like everyone to play it. It was a cute bit of promotion for Hour of Code, the computer science education event masterminded every year by the Code.org nonprofit. While the Hour of Code websites hosts one-hour tutorials (in 45 languages) for coding all sorts of simple applications, game developers may appreciate that the lion's share appears to be game projects, like the one Trudeau modified into a sort of hockey-themed Breakout variant.

Satellites cost millions of dollars to be launched into space and there's no guarantee that they will work without electrical or mechanical problems once in orbit. NASA has recently announced that it will award a $127 million contract to a company that aims to use a robotic spacecraft to fix satellites in space, thus potentially saving millions of dollars in the long-run by fixing satellites that would otherwise be "expensive e-waste." Gizmodo reports: NASA has just announced that it will award a $127 million contract to the California-based satellite company Space Systems/Loral for Restore-L, a robotic spacecraft capable of grasping, refueling and relocating a satellite in low Earth orbit, in addition to testing technologies for future missions. SSL has three years to build the bot, which is projected to launch in 2020. Without the ability to refuel, a satellite's lifespan is restricted by the amount of propellant engineers can pack in its tank at launch. That lifespan can be cut even shorter should the spacecraft encounter any electrical or mechanical problems on orbit. As more and more satellites reach the end of their operational lifespans, government agencies and private companies have been working to remedy this problem by developing robots that can give satellites a tune-up in zero-gravity. DARPA, for instance, recently launched a program aimed at designing robots capable of servicing satellites at the hard-to-reach but highly-desirable perch of geosynchronous orbit, 22,000 miles above Earth. NASA's Satellite Servicing Division, meanwhile, has a handful of on-orbit repair and refueling technology demonstrators in the works, including a robotic arm with the same range of motion as a human arm, a navigation system designed to help robots rendezvous with moving objects in space, and Restore-L, which combines these and other capabilities into a multi-purpose space mechanic. For now, Restore-L's primary goal is to refuel Landsat 7, a critical Earth-monitoring satellite operated by NASA and the U.S. Geological Survey. If successful, the spacecraft may be modified for all sorts of other useful tasks, from mopping up the ever-growing halo of space junk encircling our planet, to servicing exciting new science missions like the Asteroid Redirect Mission, which will grab a multi-ton boulder from the surface of an asteroid and tow it back to orbit around the Moon.

An anonymous reader quotes a report from The Verge: Microsoft polled 17 women working in its research organization about the technology advances they expect to see in 2017, as well as a decade later in 2027. The researchers' predictions touch on natural language processing, machine learning, agricultural software, and virtual reality, among other topics. For virtual reality, Mar Gonzalez Franco, a researcher in Microsoft's Redmond lab, believes body tracking will improve next year, and then over the next decade we'll have "rich multi-sensorial experiences that will be capable of producing hallucinations which blend or alter perceives reality." Haptic devices will simulate touch to further enhance the sensory experience. Meanwhile, Susan Dumais, a scientist and deputy managing director at the Redmond lab, believes deep learning will help improve web search results next year. In 2027, however, the search box will disappear, she says. It'll be replaced by search that's more "ubiquitous, embedded, and contextually sensitive." She says we're already seeing some of this in voice-controlled searches through mobile and smart home devices. We might eventually be able to look things up with either sound, images, or video. Plus, our searches will respond to "current location, content, entities, and activities" without us explicitly mentioning them, she says. Of course, it's worth noting that Microsoft has been losing the search box war to Google, so it isn't surprising that the company thinks search will die. With global warming as a looming threat, Asta Roseway, principal research designer, says by 2027 famers will use AI to maintain healthy crop yields, even with "climate change, drought, and disaster." Low-energy farming solutions, like vertical farming and aquaponics, will also be essential to keeping the food supply high, she says. You can view all 17 predictions here.

Apple has launched Single Sign-on, a service designed to make logging into TV apps much less annoying. It "allows cable subscribers to sign in once with their cable credentials to gain access to all cable-restricted content in iOS and tvOS apps," writes Juli Clover via MacRumors: Single Sign-on is limited to the United States, and according to a support document, is available for the following providers: CenturyLink Prism, DirecTV, Dish, GVTC, GTA, Hawaiian Telecom, Hotwire, MetroCast, and Sling. While Single Sign-on was introduced and tested in the tvOS 10.1 and iOS 10.2 betas, the feature was remotely released today to all iOS 10 and tvOS 10 devices. Using Single Sign-on does not require one of the betas, and is instead immediately available to all iPhone and Apple TV users running iOS 10 or tvOS 10. With Single Sign-on, customers with a supported provider will use the Settings options in iOS or tvOS to sign in with their cable credentials. From then on, when accessing a supported app that requires a cable subscription, the app will ask to use the saved sign-on credentials. Most cable channels and content providers offer individual apps on the Apple TV and iOS devices, but still require cable authentication before users can access content. Prior to Single Sign-on, customers were required to enter their credentials in each individual app, a frustrating and time-consuming process.

A team of former Samsung engineers have developed a smart umbrella, dubbed Opus One, that tells its owner if it's going to rain with the shake of the handle. International Business Times reports: Developed by a team of former Samsung engineers, Opus One smart umbrella works when it is connected to the smartphone via Bluetooth 4.1 through its companion app Jonas. The device gets weather reports every morning from credible sources and sends alert to its owner when its handle is shaken. Red light on the device indicates rain on that particular day, while a green one indicates clear skies. Jonas collects weather data of select cities and sends the information to Opus One smart umbrella, thus helping the owner to know if it's going to rain on a particular day. The device notifies its owner by vibrating if the smartphone connected to the app receives calls, emails or text messages. The smart umbrella also vibrates if its owner leaves behind the smartphone that is connected to it before the user gets too far away. The smartphone too will vibrate and alert its owner if the smart umbrella is left behind. This will help prevent loss of both the products. The umbrella runs on AAA batteries and costs about $105.

An anonymous reader quotes a report from Phys.Org: Scientists have developed a mind-controlled robotic hand that allows people with certain types of spinal injuries to perform everyday tasks such as using a fork or drinking from a cup. The low-cost device was tested in Spain on six people with quadriplegia affecting their ability to grasp or manipulate objects. By wearing a cap that measures electric brain activity and eye movement the users were able to send signals to a tablet computer that controlled the glove-like device attached to their hand. Participants in the small-scale study were able to perform daily activities better with the robotic hand than without, according to results published Tuesday in the journal Science Robotics. It took participants just 10 minutes to learn how to use the system before they were able to carry out tasks such as picking up potato chips or signing a document. According to Surjo R. Soekadar, a neuroscientist at the University Hospital Tuebingen in Germany and lead author of the study, participants represented typical people with high spinal cord injuries, meaning they were able to move their shoulders but not their fingers. There were some limitations to the system, though. Users had to have sufficient function in their shoulder and arm to reach out with the robotic hand. And mounting the system required another person's help.

Last month, Apple announced a repair program for a "small number" of iPhone 6s phones that suffer from faulty batteries. The phones that were affected by this fault were manufactured between September and October 2015. Two weeks later, Apple now says the fault was caused by overexposure to "controlled ambient air." Ars Technica reports: The same press release -- issued only in China so far, but available in English if you scroll down -- says that some owners of later iPhone 6S models are also reporting problems with unexpected shutdowns. Apple isn't replacing those batteries just yet, but the company says that an iOS update "available next week" will add "additional diagnostic capability" that will allow Apple to better track down and diagnose the causes of these shutdowns. It "may potentially help [Apple] improve the algorithms used to manage battery performance and shutdown," as well. Those improvements will be included in future iOS updates. Apple says that the battery problem "is not a safety issue," an important thing to note given the way the Galaxy Note 7 blew up in Samsung's face. The software update that Apple mentions in the release is almost certainly iOS 10.2, which is currently in its sixth beta build. The update will be the first major bug-fix release since October's iOS 10.1, and it also includes a handful of other changes like new and redesigned emoji, the TV app that Apple demoed at its last product event, and other features.

Some headphones marketed for children may not restrict enough noise for young ears. From a report on ABC: The Wirecutter, a technology products review website (owned by the New York Times), tried out 30 different children's headphones for style, fit and safety by using both a plastic model ear and a few real children. "There's no governing board that oversees this," Lauren Dragan, the Headphone Editor at The Wirecutter, told "Good Morning America" in an interview that aired today. Dragan added that the headphones for children all claim to limit volume to around 85 decibels. Sound below the 85 decibel mark for a maximum of eight hours is considered safe, according to the World Health Organization. The Wirecutter report found that some of these headphones emit sound higher than the 85 decibel mark. The full report here.

Samsung is planning to ditch headphone jack in its next flagship smartphone, called the Samsung Galaxy S8, reports SamMobile, a Samsung-focused blog that has a pretty good track record with these things. From the report: Removing the 3.5mm headphone jack enables Samsung to make the Galaxy S8 thinner while also freeing up more space inside for a bigger battery. Samsung may also integrate stereo speakers which some believe will be made in collaboration with Harman, a company that Samsung is acquiring for $8 billion.

Google said today it will power 100 percent of its sprawling data centers and offices with renewable energy starting next year. The company said today it has bought enough wind and solar power to account for all the electricity it uses globally each year. In comparison, 44 percent of Google's power supplies came from renewables last year. From a blogpost: To reach this goal we'll be directly buying enough wind and solar electricity annually to account for every unit of electricity our operations consume, globally. And we're focusing on creating new energy from renewable sources, so we only buy from projects that are funded by our purchases. Over the last six years, the cost of wind and solar came down 60 percent and 80 percent, respectively, proving that renewables are increasingly becoming the lowest cost option. Electricity costs are one of the largest components of our operating expenses at our data centers, and having a long-term stable cost of renewable power provides protection against price swings in energy.

Security experts consider the aging FTP and Telnet protocols unsafe, and HP has decided to clamp down on access to networked printers through the remote-access tools. From a report on PCWorld: Some of HP's new business printers will, by default, be closed to remote access via protocols like FTP and Telnet. However, customers can activate remote printing access through those protocols if needed. "HP has started the process of closing older, less-maintained interfaces including ports, protocols and cipher suites" identified by the U.S. National Institute of Standards and Technology as less than secure, the company said in a statement. In addition, HP also announced firmware updates to existing business printers with improved password and encryption settings, so hackers can't easily break into the devices.

Though several companies are struggling to sell their smartwatches, Apple CEO Tim Cook says sales of Apple Watch set a record during the first week of holiday shopping. Cook added that the current quarter is on track to be the best ever for the product. The only problem: The company, which loves to numbers do all the talking, won't disclose how many Apple Watch units were shipped or sold. From a report on Mashable: "During the first week of holiday shopping, our sell-through of Apple Watch was greater than any week in the product's history. And as we expected, we're on track for the best quarter ever for Apple Watch," Cook told Reuters in an email. This is not surprising: The company has never revealed any sales data for the Watch, bundling it with the "other products" category in its earnings reports. There have been quite a few attempts to extrapolate what this means in numbers, but the truth is that any of those attempts could be a few million units wrong either way.

Microsoft's response to the Amazon Echo and Google Home is Home Hub, a software update for Windows 10's Cortana personal assistant that turns any Windows PC into a smart speaker of sorts. Mashable reports: Microsoft's smart digital assistant Cortana can already answer your queries, even if the PC's screen is locked. The Home Hub is tied to Cortana and takes this a few steps further. It would add a special app with features such as calendar appointments, sticky notes and shopping lists. A Home Hub-enabled PC might have a Welcome Screen, a full-screen app that displays all these, like a virtual fridge door. Multiple users (i.e. family members) could use the Home Hub, either by authenticating through Windows Hello or by working in a family-shared account. Cortana would get more powerful on Home Hub; it could, for example, control smart home devices, such as lights and locks. And even though all of this will work on any Windows 10 device -- potentially making the PC the center of your smart home experience -- third-party manufacturers will be able to build devices that work with Home Hub. You can read Windows Central's massive report here. Do note that Home Hub is not official and individual features could change over time. The update is slated for 2017.

OLED panels have always been known to have higher contrast ratios than LCD panels, but that may be about to change with Panasonic's recently announced LCD IPS display. The display boasts a 1,000,000:1 contrast ratio, which is up to 600 times more contrast than some of the company's conventional LCD panels that tend to offer around 1800:1 ratios, and rivals OLED specifications. Android Authority reports: Panasonic has accomplished this through the use of its new light modulating cell technology, which allows the company to switch off individual pixels in the display using a secondary control layer. Typically, LCD backlights mean that either the entire or only large parts of the display can be dimmed at any one time. OLED panels switch off lights entirely for a black pixel to offer very high contrast ratios, and this new LCD technology works on a very similar principle. This is particularly important for reproducing HDR video content, which is becoming increasingly popular. Furthermore, this new light modulating cell technology allows Panasonic to increase the peak brightness and stability of the display, which can reach 1,000 cd/m2 while also providing HDR colors. Many other HDR TV panels top out in the range of 700 to 800 cd/m2, so colors, highlights, and shadows should appear vivid and realistic. Panasonic plans to ship the new display starting in January 2017 with sizes ranging from 55 to 12 inches.

Engineers with manufacturing technology company Instrumental tore apart a Galaxy Note 7 to try and figure out what may have caused some devices to overheat and explode, causing Samsung to recall and eventually cancel all Galaxy Note 7 devices. In their damning new report, the engineers discovered the root of the problem appears to be that the battery is too tightly packed inside the body of the Note 7. Digital Trends reports: They discovered the battery was so tightly packed inside the Galaxy Note 7's body that any pressure from battery expansion, or stress on the body itself, may squeeze together layers inside the battery that are never supposed to touch -- with explosive results. Batteries swell up under normal use, and we place stress on a phone's body by putting it our pocket and sitting down, or if it's dropped. Tolerances for battery expansion are built into a smartphone during design, and Instrumental notes Samsung used "a super-aggressive manufacturing process to maximize capacity." In other words, the Galaxy Note 7 was designed to be as thin and sleek as possible, while containing the maximum battery capacity for long use, thereby better competing against rival devices such as the iPhone 7 Plus and improving on previous Note models. The report speculates that any pressure placed on the battery in its confined space may have squeezed together positive and negative layers inside the cell itself, which were thinner than usual in the Note 7's battery already, causing them to touch, heat up, and eventually in some cases, catch fire. Delving deeper into the design, the engineers say the space above a battery inside a device needs a "ceiling" that equates to approximately 10 percent of the overall thickness. The Galaxy Note 7 should have had a 0.5mm ceiling; it had none.

An anonymous reader shares a report on BetaNews:Although artificial intelligence (AI), robotics and other emerging technologies may reshape the world as we know it, a new global study has revealed that the many CEOs now value technology over people when it comes to the future of their businesses. The study was conducted by the Los Angeles-based management consultant firm Korn Ferry that interviewed 800 business leaders across a variety of multi-million and multi-billion dollar global organizations. The firm says that 44 percent of the CEOs surveyed agreed that robotics, automation and AI would reshape the future of many work places by making people "largely irrelevant." The global managing director of solutions at Korn Ferry Jean-Marc Laouchez explains why many CEOs have adopted this controversial mindset, saying: "Leaders may be facing what experts call a tangibility bias. Facing uncertainty, they are putting priority in their thinking, planning and execution on the tangible -- what they can see, touch and measure, such as technology instruments."

America's Transportation Security Administration has been making some surprising announcements on social media. An anonymous reader writes: A TSA spokesperson says 70 laptops were left behind in just one month at an airport security checkpoint in Newark. "And yes, there are plenty of shiny MacBooks in that pile," reported BravoTV, "which can cost in the $2,000 range new." The TSA shared an image of the 70 laptops on their Instagram page and on Twitter, prompting at least one mobile project designer to reclaim his laptop. "The most common way laptops are forgotten is when traveler's stack a bin on top of the bin their laptop is in," the TSA warns. "Out of sight out of mind."
The TSA is also sharing pictures on social media of the 70 guns they confiscated at security checkpoints in one week in November, reporting they've also confiscated a blowtorch, batarangs, and a replica of that baseball bat from "The Walking Dead". They're reporting they found 33 loaded firearms in carry-on luggage in one week, and remind readers that gun-carrying passengers "can face a penalty as high as $11,000. This is a friendly reminder to please leave these items at home."

Remember that story about the "artificial leaf" solar cells? Long-time Slashdot reader managerialslime quotes the Chicago Tribune: University of Illinois at Chicago researchers have developed a way to mimic plants' ability to convert carbon dioxide into fuel, a way to decrease the amounts of harmful gas in the atmosphere and produce clean energy. The artificial leaf essentially recycles carbon dioxide. And it's powered entirely by the sun, mimicking the real photosynthesis process.
But meanwhile, in Germany: Biochemists led by Tobias Erb at the Max Planck Institute for Terrestrial Microbiology...have developed a new, super-efficient method for living organisms to suck CO2 out of the atmosphere. Plants, algae, and other organisms turn CO2 into fuel. Erb and his colleagues reengineered this process, making it about 25 percent more energy efficient and potentially up to two or three times faster... Erb hopes that one day the CETCH cycle could be genetically engineered into living organisms, helping them more rapidly reduce atmospheric CO2 while producing useful materials.
The researchers created their new CO2-transforming cycle using 11 carefully chosen enzymes.

Bre PettisâS once said MakerBot gave you a superpower -- "You can make anything you need." But four years later, mirandakatz writes that though MakerBot promised to revolutionize society, "That never happened." At Backchannel, Andrew Zaleski has the definitive, investigative account of why the 3D printing revolution hasn't yet come to pass, culled from interviews with industry observers, current MakerBot leadership, and a dozen former MakerBot employees. As he tells it, "In the span of a few years, MakerBot had to pull off two very different coups. It had to introduce millions of people to the wonders of 3D printing, and then convince them to shell out more than $1,000 for a machine. It also had to develop the technology fast enough to keep its customers happy. Those two tasks were too much for the fledgling company."

Long-Time Slashdot reader sconeu is finally replacing his 10-year-old Toshiba Satellite laptop, and needs suggestions on the best current laptops for running Linux. I'm looking to run some flavor of Linux (probably KDE-based UI, but not mandatory) while using a virtual machine to run Windows 7 (for stuff needed for work). For me personally, battery life and weight are more important than raw power. I'm not going to be running games on this. I've been considering an XPS 13 Developer Edition, or something from System76, ZaReason or Emperor Linux. What laptop do you use? Do you have any suggestions?
