Google Play Shows Warning To Anyone Searching For Fortnite APKs (betanews.com) 83
Mark Wilson quotes a report from BetaNews: The arrival of Fortnite on Android has not only been eagerly awaited, but also steeped in controversy. In addition to making the game a Samsung exclusive (for a few days, anyway), Epic Games decided to bypass Google Play and host APK downloads on its own servers. But this isn't going to stop people looking for Fortnite in the Play Store. Google is well aware of this, and that there is the potential for fake, scam apps to appear, tricking users into downloading something malicious. As such, the company is taking action, and is showing a warning to anyone who searches for Fortnite in Google Play. Conduct a search for Fortnite in Google's app store and you'll be greeted by a message that reads "Fortnite Battle Royale by Epic Games, Inc is not available on Google Play." Searchers are also advised that Fortnite rival PlayerUnknown's Battlegrounds (PUBG) is available to download.
Submission + - SPAM: The Next Falcon Heavy Will Carry the Most Powerful Atomic Clock Ever Launched
schwit1 writes: This isnt your average timekeeper. The so-called Deep Space Atomic Clock (DSAC) is far smaller than Earth-bound atomic clocks, far more precise than the handful of other space-bound atomic clocks, and more resilient against the stresses of space travel than any clock ever made. According to a NASA statement, its expected to lose no more than 2 nanoseconds (2 billionths of a second) over the course of a day. That comes to about 7 millionths of a second over the course of a decade.
Every deep-space mission that makes course corrections needs to send signals to ground stations on Earth. Those ground stations rely on atomic clocks to measure just how long those signals took to arrive, which allows them to locate the spacecrafts position down to the meter in the vast vacuum. They then send signals back, telling the craft where they are and where to go next.
Thats a cumbersome process, and it means any given ground station can support only one spacecraft at a time. The goal of DSAC, according to a NASA fact sheet, is to allow spacecraft to make precise timing measurements onboard a spacecraft, without waiting for information from Earth.
A DSAC-equipped spacecraft, according to NASAs statement, could calculate time without waiting for measurements from Earth — allowing it to make course adjustments or perform precision science experiments without pausing to turn its antennas earthward and waiting for a reply.

Submission + - College Senior Upgrades His Honda Civic to Drive Itself Using Free Software (technologyreview.com)
holy_calamity writes: University of Nebraska student Brevan Jorgenson swapped the rear view mirror in his 2016 Honda Civic for a home-built device called a Neo, which can steer the vehicle and follow traffic on the highway. Jorgenson used hardware designs and open source software released by Comma, a self-driving car startup that decided to give away its technology for free last year after receiving a letter from regulator the NHTSA. Jorgenson is just one person in a new hacker community trying to upgrade their cars using Comma's technology.
Submission + - SPAM: Researchers hack Philips Hue smart bulbs from the sky
schwit1 writes: Researchers were able to take control of some Philips Hue lights using a drone. Based on an exploit for the ZigBee Light Link Touchlink system, white hat hackers were able to remotely control the Hue lights via drone and cause them to blink S-O-S in Morse code.
The drone carried out the attack from more than a thousand feet away. Using the exploit, the researchers were able to bypass any prohibitions against remote access of the networked light bulbs, and then install malicious firmware. At that point the researchers were able to block further wireless updates, which apparently made the infection irreversible.
“There is no other method of reprogramming these [infected] devices without full disassemble (which is not feasible). Any old stock would also need to be recalled, as any devices with vulnerable firmware can be infected as soon as power is applied,” according to the researchers.
The researchers notified Philips of the vulnerability. The company then delivered a patch for it in October.

It wasn’t long ago that claiming “Drones are controlling my lightbulbs!” would have gotten you locked up for your own protection.

Submission + - ReactOS 0.4.2 Officially Released (with introduced dot.NET 2.0/4.0 support) (reactos.org)
jeditobe writes: Version 0.4.2 of ReactOS, the open-source binary-compatible Windows re-implementation, is now officially available.
What’s more appealing in ReactOS 0.4.2 is it includes the ability to read and write various file systems for Linux/Unix namely ext family and Btrfs and ability to read such file systems as ReiserFS and UFS.
ReactOS 0.4.2 also features Cygwin support, .NET 2.0 (https://jira.reactos.org/browse/CORE-6382) and 4.0 (https://jira.reactos.org/browse/CORE-11266) application support, among other updated packages and revised external dependencies such as Wine and UniATA. The team also worked to improve overall user experience.
ReactOS support has improved to the point that games like Elder Scrolls: Skyrim (https://www.youtube.com/watch?v=hJTL8srScQI) and Doom 3 (https://www.youtube.com/watch?v=rluGgjcXtEY) should even be playable on this "open-source Windows" OS along with applications like Thunderbird and 7-Zip.
ReactOS is free. You can boot your desktop or laptop from it. It looks like Windows (a 10-year-old version, anyway), so you already know how to use it. And it'll run some Windows and DOS applications, maybe including DOS games that regular 64-bit Windows can no longer touch.

Submission + - NASA Funds Plan To Turn Used Rocket Fuel Tanks Into Space Habitats (ieee.org)
An anonymous reader writes: A couple of weeks ago NASA announced it has committed $65 million to six companies over the course of two years for the purpose of developing and testing deep-space habitats that could be used for future missions to Mars. One of the six companies, called NanoRacks, is attempting to take empty fuel tanks from the upper stages of rockets and turn them into space habitats on-orbit. IEEE Spectrum reports: "A rocket like the the Atlas V, which can deliver payloads of nearly 19,000 kg to low Earth orbit, consists of three primary pieces: on the bottom, you've got the first stage booster, which consists of a huge engine and some big tanks holding kerosene fuel and oxidizer. Above that, there's the second stage, which consists of one or two smaller engines, a big tank for storing liquid hydrogen fuel, and a smaller tank for oxidizer. The payload, which is what all of the fuss is about, sits on top. The first stage launches the rocket off of the pad and continues firing for about four minutes. Meanwhile, the second stage fires up its own engine (or engines) to boost the payload the rest of the way into orbit. On the Atlas V, the second stage is called Centaur. Once Centaur gets its payload where it needs to go, it separates, and then suicides down into Earth's atmosphere. Getting a payload into space is so expensive because you have to build up this huge and complicated rocket, with engines and guidance systems and fuel tanks and stuff, and then you basically use it for like 15 minutes and throw it all away. But what about the second stage? You've got a whole bunch of hardware that made it to orbit, and when getting stuff to orbit costs something like $2,500 per kilogram, you then tell it to go it burn itself up in the atmosphere, because otherwise it's just useless space junk." NanoRacks thinks this is wasteful, so they want to turn these tanks into deep space habitats. IEEE notes that the hydrogen fuel tank on a Centaur upper stage has a diameter of over 4 meters, and an interior volume of 54 cubic meters, while the inflatable BEAM module that arrived at the ISS earlier this year has an interior volume of 16 cubic meters.

An anonymous reader writes: Google's Project Magenta, which aims to use machine learning to create music and art, just created its first song.

Star Wars is 30 Years Old 223
javipas writes "On May 25th, 1977 the first film of the Star Wars Saga was released to theaters. Thirty years later, and celebrations are being held all around the globe. Wired has a series of articles entitled The Empire at 30, and many fans are posting about this particular birthday. For example, you can see the best 30 clips made by fans to celebrate this anniversary. The BBC is chronicling the journey of one man who had never seen Star Wars before. IGN has a rundown on some of the highlights of the Celebration convention, running this weekend."
