Slashdot reader chicksdaddy quotes an article from Security Ledger:
The Federal Trade Commission is warning consumers to beware of new 'connected car' features that allow rental car customers to connect their mobile phone or other devices to in-vehicle infotainment systems. "If you connect a mobile device, the car may also keep your mobile phone number, call and message logs, or even contacts and text messages," the FTC said in an advisory released on Tuesday. "Unless you delete that data before you return the car, other people may view it, including future renters and rental car employees or even hackers."
The Commission is advising renters to avoid syncing their mobile phones to their rental car, or to power devices via a USB port, where settings on your device may allow automatic syncing of data. Consumers who do connect their device should scrutinize any requests for permissions.
Security researchers have also discovered another car-related vulnerability. The software connecting smartphones to in-vehicle "infotainment" systems could also make cars vulnerable to remote attacks.Read Replies (0)

NASA will land a new probe on Mars on November 26, 2018, "paving the way toward an ambitious journey to send humans to the Red Planet," according to one NASA official. The $828 million project will investigate how the planet was formed, NASA announced Friday, calling it "an unparalleled opportunity to learn more about the internal structure of the Red Planet."
Meanwhile, long-time Slashdot reader taiwanjohn shares an editorial published by Ars Technica the same day, titled "We love you SpaceX, and hope you reach Mars. But we need you to focus." Noting that SpaceX receives the majority of its funding from NASA, the site's senior space editor writes that the company's business model requires that they ultimately deliver a reusable launch system.
"I understand SpaceX has a master plan -- the company wants to colonize Mars... But at some point you have to focus on the here and now, and that is the Falcon 9 rocket... if there is no Falcon 9, there is no business."
In a related story, Saturday NASA's history office shared a photograph from the Viking 2's landing on the surface of Mars -- which happened exactly 40 years ago.Read Replies (0)

An anonymous Slashdot reader quotes BetaNews about new legal documents filed Friday:
Microsoft is fighting the US Justice Department in an attempt to quash a law that prevents companies informing customers that the government is requesting their data. The technology giant has the backing of other tech companies as well as media outlets. Amazon, Apple, Google, Fox News, Electronic Frontier Foundation and Mozilla are among those offering their support to Microsoft. The lawsuit says that blocking companies from keeping their customers informed is unconstitutional, and it comes at a time when tech companies in particular are keen to be as open and transparent as possible about government requests for data....
As EFF Senior Staff Attorney Lee Tien puts it: "Whether the government has a warrant to rifle through our mail, safety deposit boxes, or emails stored in the cloud, it must notify people about the searches. When electronic searches are done in secret, we lose our right to challenge the legality of law enforcement invasions of privacy. The Fourth Amendment doesn't allow that, and it's time for the government to step up and respect the Constitution."
Mozilla argues transparency "is critical to our vision of an open, trusted, secure web that places users in control of their experience online," in a blog post announcing that they'd joined a brief filed by Apple, Twilio, and Lithium Technologies.
And a statement from an EFF staff attorney argues that notifying the targets of searches "provides a free society with a crucial means of government accountability."Read Replies (0)

"Researchers at the University of Wisconsin-Madison are the first to have fabricated carbon nanotube transistors (CNTs) that outperform the current-density of conventional semiconductors like silicon and gallium arsenide," reports NanotechWeb.
Slashdot reader wasteoid
shares the site's interview with one of the researchers:
"When the transistors are turned on to the conductive state (meaning that current is able to pass through the CNT channel) the amount of current traveling through each CNT in the array approaches the fundamental quantum limit," he tells nanotechweb.org.
"Since the CNTs conduct in parallel, and the packing density and conductance per tube are very high, the overall current density is very high too -- at nearly twice that of silicon's. The result is that these CNT array FETs have a conductance that is seven times higher than any previous reported CNT array field-effect transistor."
The research was funded in part by the U.S. Army and Air Force, as well as the National Science Foundation. "The implication here is that by replacing silicon with a CNT channel, it should be possible for us to make either a higher performing device or one that works at lower power." In other news, Fujitsu announced this week that it's joining an effort to release a 256-megabyte 55-nanometer carbon nanotube-based NRAM by 2018.Read Replies (0)

The Guardian has an opinion piece by Richard Stallman which argues that we should be able to pay for news anonymously. From the article: "Online newspapers and magazines have come to depend, for their income, on a system of advertising and surveillance, which is both annoying and unjust... What they ought to do instead is give us a truly anonymous way to pay."
He also (probably not coincidentally) has developed a method to do just that. "For the GNU operating system, which was created by the free software movement and is typically used with the kernel Linux, we are developing a suitable payment system called GNU Taler that will allow publishers to accept anonymous payments from readers for individual articles."
Publishers "can profit from defending privacy rather than from exposing their readers," argues Stallman, ending his article with a simple plea. "Publishers, please let me pay you -- anonymously!"Read Replies (0)

An anonymous reader quotes Softpedia: Anthony Di Iorio, founder of Jaxx, a crypto-currency wallet, claims that an Apple representative revealed to him the six crypto-currencies allowed on the App Store, during a private phone conversation... Di Iorio had this conversation with the Apple employee after the company removed his Jaxx iOS app from the store. The Apple employee told Di Iorio that they had to remove his app because it featured support for Dash, another blockchain technology, touted as an alternative to Bitcoin. During the conversation, Di Iorio asked what crypto-currencies Apple approves of, so he'd know what to remove from Jaxx's iOS version and get his app back on the App Store. Di Iorio says that Apple is comfortable approving apps on its App Store that handle only six crypto-currencies: Bitcoin, Dogecoin, Litecoin, Ethereum, the DAO and Ripple. Reaction to Apple's list of approved crypto-currencies wasn't positive, at least on Twitter. Most users criticized Apple's decision to limit the list to only six, which they considered might thwart the evolution of other, lesser-known crypto-currencies.
Vitalik Buterin, who helped create Ethereum with Di lorio, tweeted "For the record: despite being a beneficiary of this instance of (private) regulatory protectionism, I oppose it."Read Replies (0)

Long-time Slashdot reader RockDoctor writes: Remember the screaming and welcoming of our Dyson-Sphere-Dwelling 1500 LY distant Overlords that accompanied the news that star KIC 8462852 was irregularly dimming on both short and longer timescales? A second star with a similar light curve has been discovered and reported on ARXIV. With the euphonious names "EPIC 204278916" and "2MASS J16020757-2257467", the star is a young M1 (red) star, traveling as part of a group of stars which haven't had time to disperse from their place of formation. The age is estimated at 5 — 11 million years. Analysis of 70+ days of data from the K2 mission epoch shows a rotation of 3.6 days, but a period of 25 days near the start of the observation epoch showed dips in intensity of up to 60% lasting for up to about a day each. Details are in the Arxiv paper linked to above, particularly figures 1 and 4.
If confirmed, this discovery changes the situation with interpreting the so-called "Tabby's Star". Firstly with a second object in the class, the odds of it representing a class of naturally occurring objects compared to a unique, unusual object is greatly increased. Secondly, the different celestial mechanical situations around the different stars allows a better estimate of plausible formation mechanisms. One potentially important point is that clumps of debris that could produce these dimmings seem to be quite large. "It is also important to note that the resulting size for the transiting and occulting clump would be quite large at with the clump being in the order of 1.5 times the radius of the Sun. Sadly, this appears to be a new class of "dirty young planetary system." no alien Overlords, no screaming in the streets. Just business-like astronomy.Read Replies (0)

An anonymous Slashdot reader quotes a report from the San Jose Mercury News:
Apple CEO Tim Cook says the company plans to bring back billions of dollars in profit to the U.S. next year. Cook's statement, made during an interview with RTE radio Thursday, contradicts his previous public statements on the issue: He has said for years that U.S. corporate taxes are too high, and that the Silicon Valley company wouldn't be repatriating profit until its home country changed its tax code.
"Right now I would forecast that we repatriate next year"Cook said, saying that the company has "provisioned several billion" for that purpose.
An interesting side-note: Apple accounts for 40% of Silicon Valley's profits.Read Replies (0)

Dozens of aircraft fires have been caused by lithium batteries, and after 2013 Tesla even strengthened their battery shields after several of their cars caught on fire. An anonymous Slashdot reader quotes the AP:
Samsung's Note 7 isn't the only gadget to catch fire thanks to lithium-battery problems, which have afflicted everything from iPhones to Tesla cars to Boeing jetliners. Blame chemistry and the fact that the batteries we rely on for everyday life are prone to leaking and even bursting into flame if damaged, defective or exposed to excessive heat...
Still, lithium batteries are so ubiquitous that ordinary users of phones and computers shouldn't worry. Research suggests that you're more likely to get hurt by a kitchen grease fire or a drunk driver than the battery powering your iPhone, Kindle or laptop. "It's not like we live in a world where people's smartphones spontaneously combust," said Ramon Llamas, research manager of research firm IDC's mobile phones team. He said owners of Galaxy Note 7s should err on the side of caution and contact Samsung for a replacement that doesn't run the same risk.
The article also reports that hoverboards were linked to at least 99 electrical fires in America that were presumably caused by battery problems. "Amazon, Best Buy and other retailers dumped the products after videos of burning hoverboards went viral."Read Replies (0)

After analyzing 1.4 million scores on HackerRank's tests for coding accuracy and speed, Chinese programmers "outscored all other countries in mathematics, functional programming, and data structures challenges". Long-time Slashdot reader DirkDaring quotes a report from InfoWorld:
While the United States and India may have lots of programmers, China and Russia have the most talented developers according to a study by HackerRank... "If we held a hacking Olympics today, our data suggests that China would win the gold, Russia would take home a silver, and Poland would nab the bronze. Though they certainly deserve credit for making a showing, the United States and India have some work ahead of them before they make it into the top 25."
While the majority of scores came from America and India, the two countries ranked 28th and 31st, respectively. "Poland was tops in Java testing, France led in C++, Hong Kong in Python, Japan in artificial intelligence, and Switzerland in databases," reports InfoWorld. Ukrainian programmers had the top scores in security, while Finland showed the highest scores for Ruby.Read Replies (0)

the_newsbeagle writes: You can now buy gadgets online that send electric current through your scalp to stimulate your brain. Why would you want to do that? Because the easy technique, called transcranial direct current stimulation (tDCS), is being investigated as a treatment for depression, a rehab aid for stroke patients, a learning enhancer for healthy people, and for many other neuropsychiatric applications. However, the technique is so new that companies selling brain-zapping gadgets aren't bound by any regulations, and experts are worried that consumers will end up buying devices that aren't safe or simply aren't effective. So scientists and some manufacturers recently got together to discuss the scope of the problem, and what can be done about it. Earlier IEEE reported that "Professional basketball, baseball, and American football teams are also experimenting with it," adding that some Olympic athletes, including sprinters and swimmers, even used a premarket version of one brain-zapping device to prepare for the Olympics in Rio.Read Replies (0)

An anonymous reader writes: In a report via IEEE Spectrum, Facebook's VP of Engineering Jay Parikh described the company's "Project Storm" -- regular takedowns of Facebook's data center intended to stress test the company's disaster recovery efforts. The first few didn't go so well, he reports. (Perhaps doing a test during a World Cup final was not such a good idea). Months and months of planning went into the initial effort, though up until the actual moment, other Facebook leaders didn't think he'd actually take out an active data center. "In 2014, Parikh decided Project Storm was ready for a real-world test: The team would take down an actual data center during a normal working day and see if they could orchestrate the traffic shift smoothly," reports IEEE Spectrum. Parikh recalls: "I was having coffee with a colleague just before the first drill. He said, 'You're not going to go through with it; you've done all the prep work, so you're done, right?' I told him, 'There's only one way to find out'" if it works. (Parikh made the remarks at this week's @Scale conference in San Jose.) Parikh says there never seemed to be a good time to perform the live takedowns. "Something always ended up happening in the world or the company. One was during the World Cup final, another during a major product launch." The report adds, "The live takedowns continue today, with the Project Storm team members coming up with crazier and crazier ambitions for just what to take offline, Parikh says.Read Replies (0)

An anonymous reader writes from a report via TechCrunch: SpaceX appears to be hard at work building its Hyperloop test track through Hawthorne, a city in southwestern Los Angeles County, California. TechCrunch reports: "SpaceX is hosting a Hyperloop Pod Design Competition for student and engineering teams, and 23 winners were selected earlier this year to build their pod prototypes and race them on the test track, a 1-mile tube capable of achieving 99.8 percent vacuum. Said track was photographed by reddit user 42finder this week (via Electrek). Pod testing would be a big step for Hyperloop technology. The two main companies competing to build the first operational Hyperloop systems, Hyperloop Transportation Technologies and Hyperloop One, have yet to create pod tests. HyperloopOne has begun construction on its own test track in the Nevada desert, of course, but the SpaceX project looks considerably further along. Back when SpaceX first announced the competition, the timing of the final round which includes the actual test of final prototype pods was set for Summer 2016, but in July SpaceX announced that would slip to January of next year."Read Replies (0)
