New submitter joshtops shares a report from Scientific American: As NASA makes plans to one day send humans to Mars, one of the key technical gaps the agency is working to fill is how to provide enough power on the Red Planet’s surface for fuel production, habitats and other equipment. One option: small nuclear fission reactors, which work by splitting uranium atoms to generate heat, which is then converted into electric power. NASA’s technology development branch has been funding a project called Kilopower for three years, with the aim of demonstrating the system at the Nevada National Security Site near Las Vegas. Testing is due to start in September and end in January 2018. The last time NASA tested a fission reactor was during the 1960s’ Systems for Nuclear Auxiliary Power, or SNAP, which developed two types of nuclear power systems. The first system — radioisotope thermoelectric generators, or RTGs — taps heat released from the natural decay of a radioactive element, such as plutonium. RTGs have powered dozens of space probes over the years, including the Curiosity rover currently exploring Mars. The second technology developed under SNAP was an atom-splitting fission reactor. SNAP-10A was the first — and so far, only — U.S. nuclear power plant to operate in space. Launched on April 3, 1965, SNAP-10A operated for 43 days, producing 500 watts of electrical power, before an unrelated equipment failure ended the demonstration. The spacecraft remains in Earth orbit. Read more of this story at Slashdot.

Chinese Court Seizes Millions in Assets of LeEco Founder as Conglomerate’s Troubles Grow
Chinese Internet tycoon and LeEco founder Jia Yueting’s ambition to challenge the likes of Apple and Tesla looks even more in doubt after $182 million of his assets were frozen by a Shanghai court following unpaid loans. From a report: Jia and LeEco came in for stinging criticism from Chinese media Wednesday, which warned that the Internet streaming company and hardware manufacturer was set to fall into further trouble, with the asset freeze as only the beginning. LeEco’s development “is too big, too quick and too reckless, ” Beijing Business Today wrote. “Developing TV [programs and TV sets], mobile phones, [electric] cars and sports programs all consume too much cash at the same time. Not only can the capital not sustain these developments; fractures are inevitable in areas ranging from human resources, technology and management.” According to the official Xinhua news agency, the Shanghai High People’s Court last week ruled in favor of China Merchants Bank’s application to freeze $182 million in assets belonging to Jia, his wife and three LeEco affiliates.

‘Severe’ Systemd Bug Allowed Remote Code Execution For Two Years
ITWire reports: A flaw in systemd, the init system used on many Linux systems, can be exploited using a malicious DNS query to either crash a system or to run code remotely. The vulnerability resides in the daemon systemd-resolved and can be triggered using a TCP payload, according to Ubuntu developer Chris Coulson. This component can be tricked into allocating less memory than needed for a look-up. When the reply is bigger it overflows the buffer allowing an attacker to overwrite memory. This would result in the process either crashing or it could allow for code execution remotely. “A malicious DNS server can exploit this by responding with a specially crafted TCP payload to trick systemd-resolved in to allocating a buffer that’s too small, and subsequently write arbitrary data beyond the end of it, ” is how Coulson put it. Affected Linux vendors have pushed out patches — but the bug has apparently been present in systemd code since June of 2015. And long-time Slashdot reader walterbyrd also reports a recently-discovered bug where systemd unit files that contain illegal usernames get defaulted to root. Read more of this story at Slashdot.

California Has So Much Solar Power That Other States Are Paid To Take It
“On 14 days during March, Arizona utilities got a gift from California: free solar power, ” reported the Los Angeles Times. Mic reports: California is generating so much solar energy that it is resorting to paying other states to take the excess electricity in order to prevent overloading power lines. According to the Los Angeles Times, Arizona residents have already saved millions in 2017 thanks to California’s contribution. The state, which produced little to no solar energy just 15 years ago, has made strides — it single-handedly has nearly half of the country’s solar electricity generating capacity… When there’s too much solar energy, there is a risk of the electricity grid overloading. This can result in blackouts. In times like this, California offers other states a financial incentive to take their power. But it’s not as environmentally friendly as one would think. Take Arizona, for example. The state opts to put a pin in its own solar energy sources instead of fossil fuel power, which means greenhouse gas emissions aren’t getting any better due to California’s overproduction. The Los Angeles Times suggests over-construction of natural gas plants created part of the problem — Californians now pay roughly 50% more than the rest of the country for power — but they report that power supplies could become more predictable when battery storage technologies improve.

Equal Rights Center Sues Uber For Denying Equal Access To People Who Use Wheelchairs
The Equal Rights Center is suing Uber, alleging that the company has chosen not to include wheelchair-accessible cars as an option in its standard UberX fleet of vehicles, and excludes people who use wheelchairs in Washington, D.C. According to the lawsuit, Uber is in violation of Title 3 of the Americans with Disabilities Act and the D.C. Human Rights Act. TechCrunch reports: After conducting its own investigation of Uber’s services for people in wheelchairs, the ERC found that passengers had to wait an average of eight times longer for an accessible car to arrive. They also had to pay twice as much in fares, according to the ERC’s study. Ultimately, the ERC wants Uber to integrate wheelchair accessible cars into its UberX fleet so that people who use wheelchairs don’t have to wait longer and pay more to use the car service. Uber said in a statement provided to TechCrunch: “We take this issue seriously and are committed to continued work with the District, our partners, and stakeholders toward expanding transportation options and freedom of movement for all residents throughout the region.” Read more of this story at Slashdot.

Ethereum Exchange Reimburses Customer Losses After ‘Flash Crash’
An anonymous reader writes: “The price of ethereum crashed as low as 10 cents from around $319 in about a second on the GDAX cryptocurrency exchange on Wednesday, ” reports CNBC, calling it “a move that is being blamed on a ‘multimillion dollar market sell’ order… As the price continued to fall, another 800 stop loss orders and margin funding liquidations caused ethereum to trade as low as 10 cents.” An executive for the exchange said “Our matching engine operated as intended throughout this event and trading with advanced features like margin always carries inherent risk.” Though some users complained they lost money, the price rebounded to $325 — and according to a report on one trading site, “one person had an order in for just over 3, 800 ethereum if the price fell to 10 cents on the GDAX exchange, ” reports CNBC. “Theoretically this person would have spent $380 to buy these coins, and when the price shot up above $300 again, the trader would be sitting on over $1 million.” Yet the currency exchange announced Friday that they’re honoring everyone’s gains, while also reimbursing customers who suffered losses. “We view this as an opportunity to demonstrate our long-term commitment to our customers and belief in the future of this industry.” Read more of this story at Slashdot.

Anthem To Pay $115 Million In The Largest Data Breach Settlement Ever
An anonymous reader quotes CNET: Anthem, the largest health insurance company in the U.S., has agreed to settle a class action lawsuit over a 2015 data breach for a record $115 million, according to lawyers for the plaintiffs. The settlement still has to be approved by US District Court Judge Lucy Koh, who is scheduled to hear the case on August 17 in San Jose, California. And Anthem, which didn’t immediately respond to a request for confirmation and comment, isn’t admitting any admitting any wrongdoing, according to a statement it made to CyberScoop acknowledging the settlement. But if approved, it would be the largest data breach settlement in history, according to the plaintiffs’ lawyers, who announced the agreement Friday. The funds would be used to provide victims of the data breach at least two years of credit monitoring and to reimburse customers for breach-related expenses. The settlement would also guarantee a certain level of funding for “information security to implement or maintain numerous specific changes to its data security systems, including encryption of certain information and archiving sensitive data with strict access controls, ” the plaintiff attorneys said. The breach compromised data for 80 million people, including their social security numbers, birthdays, street addresses (and email addresses) as well as income data. The $115 million settlement averages out to $1.43 for every person who was affected. Read more of this story at Slashdot.

90 Cities Install A Covert Technology That Listens For Gunshots
An anonymous reader quotes Business Insider: In more than 90 cities across the US, including New York, microphones placed strategically around high-crime areas pick up the sounds of gunfire and alert police to the shooting’s location via dots on a city map… ShotSpotter also sends alerts to apps on cops’ phones. “We’ve gone to the dot and found the casings 11 feet from where the dot was, according to the GPS coordinates, ” Capt. David Salazar of the Milwaukee Police Dept. told Business Insider. “So it’s incredibly helpful. We’ve saved a lot of people’s lives.” When three microphones pick up a gunshot, ShotSpotter figures out where the sound comes from. Human analysts in the Newark, California, headquarters confirm the noise came from a gun (not a firecracker or some other source). The police can then locate the gunshot on a map and investigate the scene. The whole process happens “much faster” than dialing 911, Salazar said, though he wouldn’t disclose the exact time. The company’s CEO argues their technology deters crime by demonstrating to bad neighborhoods that police will respond quickly to gunshots. (Although last year Forbes discovered that in 30% to 70% of cases, “police found no evidence of a gunshot when they arrived.”) And in a neighborhood where ShotSpotter is installed, one 60-year-old man is already complaining, “I don’t like Big Brother being in all my business.” Read more of this story at Slashdot.
