Google’s mysterious Fuchsia OS looks like an Android re-do

When we last looked at Google’s Fuchsia operating system , it was very modest. While it was designed for everything from Internet of Things devices to PCs, there wasn’t even a graphical interface to show. Well, things have… evolved. Ars Technica has revisited Fuchsia several months later, and it now touts an interface (nicknamed Armadillo) that makes it clear this isn’t just some after-hours experiment. It’s only a set of placeholders at the moment, but it gives you a good idea as to what to expect. The home screen is a large, vertically scrolling list of cards for “stories, ” or collections of apps and OS components that work together to complete a given task. There’s also a Google Now -style section that has “suggestion” cards for tasks — use them and you’ll either add to an existing story or create a new one. The prototype UI also includes a simple split-screen interface, and scales up to tablet size. Fuchsia isn’t based on Linux, like Android or Chrome OS, but it still uses open source code that would let anyone tinker with the inner workings. Apps, meanwhile, are built using Google’s Flutter kit, which lets developers write both Android and iOS apps. Things are clearly coming along. But there’s one overriding question: just what role will Fuchsia have? Google’s Travis Geiselbrecht stresses that this “isn’t a toy thing, ” but there’s no public strategy. Ars speculates that Google is treating this as a sort of Android re-do: what if the company could design a platform while dumping all the technology it no longer needs or wants, such as Linux or any traces of Java ? The use of Flutter would let you run Android apps until there’s broader software support. It might take years before Fuchsia is ready for public use, assuming that’s the ultimate plan, but there could be a day where Android is no longer the center of Google’s computing universe.

New ultra-high resolution printer makes colors from nanostructures

Researchers from the Technical University of Denmark demonstrated a new nanotechnology-based printing technique that produces long-lasting color images on plastic at resolutions up to 127,000 dots per inch, many times more detailed than traditional laser printers. The system uses a laser to alter the structure of nanoscale structures on the plastic material. (A nanometer is one-billionth of a meter; a human hair is around 60,000 nanometers in diameter.) The nanoprinting technique could also lead to new kinds of 3D displays or invisible watermarks. From New Scientist : The surface of the plastic is shaped so that it has lots of tiny pillars, one roughly every 200 nanometers. A thin film of the element germanium is then spread over the plastic. Heat from a laser melts the germanium on each pillar, morphing its shape and thickness. As a result, it reflects a specific color. The coating protects the shapes of the newly carved nanostructures.

NIST’s Draft To Remove Periodic Password Change Requirements Gets Vendors’ Approval

An anonymous reader writes: A recently released draft of the National Institute of Standards and Technology’s digital identity guidelines has met with approval by vendors. The draft guidelines revise password security recommendations and altering many of the standards and best practices security professionals use when forming policies for their companies. The new framework recommends, among other things: “Remove periodic password change requirements.” There have been multiple studies that have shown requiring frequent password changes to actually be counterproductive to good password security, said Mike Wilson, founder of PasswordPing. NIST said this guideline was suggested because passwords should be changed when a user wants to change it or if there is indication of breach. Read more of this story at Slashdot.

Scientists stunned by new findings about salt’s effects on body

Conventional wisdom: If you eat a lot of salt, you will get thirsty to dilute the sodium level in your blood. The excess salt will be excreted in your urine. But a new study of Russian cosmonauts is challenging this long-held belief. When the cosmonauts ate more salt, the became less thirsty. And their appetite increased – they had to eat 25 percent more to maintain their weight. From the New York Times : The crew members were increasing production of glucocorticoid hormones, which influence both metabolism and immune function. To get further insight, [Dr. Jens Titze, now a kidney specialist at Vanderbilt University Medical Center and the Interdisciplinary Center for Clinical Research in Erlangen, Germany] began a study of mice in the laboratory. Sure enough, the more salt he added to the animals’ diet, the less water they drank. And he saw why. The animals were getting water — but not by drinking it. The increased levels of glucocorticoid hormones broke down fat and muscle in their own bodies. This freed up water for the body to use. But that process requires energy, Dr. Titze also found, which is why the mice ate 25 percent more food on a high-salt diet. The hormones also may be a cause of the strange long-term fluctuations in urine volume. Scientists knew that a starving body will burn its own fat and muscle for sustenance. But the realization that something similar happens on a salty diet has come as a revelation. https://youtu.be/aJEzl31zL-I

235 apps attempt to secretly track users with ultrasonic audio

Ultrasonic beacons ( previously , previously ) let advertisers build an idea of when and where you use your devices: the sound plays in an ad on one device, and is heard by other devices. This way, they can associate two gadgets with a single user, precisely geolocate devices without aGPS, or even build graphs of real-world social networks. The threat was considered more academic than some, but more than 200 Android apps were found in the wild using the technique . In research sponsored by the German government [PDF], a team of researchers conducted extensive tests across the EU to better understand how widespread this practice is in the real world. Their results revealed Shopkick ultrasonic beacons at 4 of 35 stores in two European cities. The situation isn’t that worrisome, as users have to open an app with the Shopkick SDK for the beacon to be picked up. In the real world, this isn’t an issue, as store owners, advertisers, or product manufactures could incentivize users to open various apps as a way to get discounts. From the paper: While in April 2015 only six instances were known, we have been able to identify 39 further instances in a dataset of about 1,3 million applications in December 2015, and until now, a total of 234 samples containing SilverPush has been discovered. We conclude that even if the tracking through TV content is not actively used yet, the monitoring functionality is already deployed in mobile applications and might become a serious privacy threat in the near future Apparently it’s not very effective—consumer speakers and mics aren’t designed with ultrasonic use in mind and the authors say noise, audio compression and other factors “significantly affects the feasibility” of the technology—but the intent is clearly there on the part of advertisers and appmakers to make a stab at it. Annoyingly, there doesn’t seem to be a list of the apps that are doing this, but there is a reference to a McDonalds app. If an app asks for access to your device’s microphone, camera, etc., and you don’t know why, delete the app.

Workhorse W-15 revealed: PHEV pickup with 80-mile range

Not even a year after releasing renderings of its new range-extended electric truck , Workhorse has unveiled the real thing. As promised, the new Workhorse W-15 uses a pair of electric motors, one in the front and one in the back, for propulsion, along with a BMW gas engine and Panasonic batteries to supply power. Impressively, the truck is rated to go 80 miles on a full charge, and it will manage 32 mpg highway and 28 mpg city with the gas engine in use. While delivering these environmentally friendly numbers, the W-15 won’t be lacking in performance and usability. The dual motors produce 460 horsepower and deliver that power to all four wheels. As a result, Workhorse says it will go 0-60 mph in just 5.5 seconds. The W-15 can also carry up to 2, 200 pounds of cargo in its bed, and it has a 7.2kW, 30-amp power outlet on the side suitable for running power tools. The only weak point in the truck’s capability is towing, which is rated at 5, 000 pounds. For comparison, a base, V6-powered Chevrolet Silverado will tow 7, 600 pounds , and a Ford F-150 with the smallest EcoBoost V6 can tow up to 8, 500 pounds . Of course neither is as economical nor as powerful. The W-15’s performance isn’t let down by the exterior, either. The exterior is chiseled and chunky, with no shortage of flat planes and sharp angles. It screams tough commercial truck . The look is carried inside to the custom dashboard, too, with lots of tough plastic in gray, white, and orange. The interior is quite spartan, with hardly any controls except a simple dial for shifting in the center. Instruments and infotainment are displayed on two LCD screens, with the infotainment one controlled via touch. Even though the truck is fairly barebones, Workhorse has included dual airbags , automatic emergency braking, and lane-departure warning. The Workhorse W-15 is aimed primarily at the commercial market, and demand appears to be high. The company says it currently has 4, 650 pre-orders . Pricing hasn’t been announced, but Workhorse intends to deliver trucks next year. We think this truck could have some strong appeal to private consumers as well, however the company hasn’t announced plans for personal-use sales. Related Video: Source: Workhorse

LAX’s New Private Luxury Terminal For The Rich Is The Most Obnoxiously LA Thing Ever

The one thing that helped me combat my irritation at being at an airport was the knowledge that airports are the great social equalizer: generally, it doesn’t matter who you are—rich, poor, famous, normal, whatever—you still have to check-in, go through security and get on the moving sidewalks to your gate. It sucks… Read more…

California utility augments 1,800 air conditioning units with “ice battery”

Ice Energy A Santa Barbara-based company called Ice Energy has partnered with NRG Energy to deliver 1,800 “ice batteries” to commercial and industrial buildings served by electric utility Southern California Edison (SCE). The units are expected to reduce air conditioning bills by up to 40 percent and eliminate 200,000 tons of CO 2 over the next 20 years. Ice Energy has been building ice-based cooling systems since the early 2000s. Much like pumped storage or compressed air “batteries,” Ice Energy essentially stores electricity by drawing power from the grid at non-peak times to freeze water in a special container. Then at peak times, when the cost of electricity is high and grid operators are struggling to keep up with demand, Ice Energy’s systems kick in and use that block of ice to cool the space that the air conditioning unit normally serves.
