Ethereum Exchange Reimburses Customer Losses After 'Flash Crash'

Slashdot - Sun, 06/25/2017 - 20:34
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."

90 Cities Install A Covert Technology That Listens For Gunshots

Slashdot - Sun, 06/25/2017 - 19:34
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."

Self-Driving Cars Are Safer When They Talk To Each Other

Slashdot - Sun, 06/25/2017 - 18:34
An anonymous reader quotes Engadget: A University of Michigan public-private partnership called Mcity is testing V2V, or vehicle to vehicle communication, and has found that it makes their autonomous prototypes even safer. V2V works by wirelessly sharing data such as location, speed and direction. Using DSRC, or Dedicated Short Range Communication, V2V can send up to 10 messages per second. This communication allows cars to see beyond what is immediately in front of them -- sensing a red light around a blind curve, or automatically braking for a car that runs a stop sign... The catch of V2V? It has to be installed in the majority of cars and infrastructure (such as traffic lights) to function adequately.

Los Angeles Tests Reflective 'Cool Pavement' On Streets

Slashdot - Sun, 06/25/2017 - 17:34
mikeebbbd writes: As reported in the Los Angeles Daily News, during the current heatwave various officials swooped down on streets coated with an experimental light-gray sealer that makes the old asphalt into a "cool street" -- and it works, with average temperature differences between coated streets and adjacent old asphalt around 10F. At a large parking lot, the temperature reduction was over 20F. If the material holds up and continues to meet other criteria, LA plans to use it on more pavement rehab projects, which could eventually make a difference in the heat island effect. The "CoolSeal" coating is apparently proprietary to a company named GuardTop LLC, costs $25-40K/mile, and lasts 5-7 years. At that price, it's might not be used a lot, at least at first; typical slurry seals run $15-30K/mile.

Software Developer Explains Why The Ubuntu Phone Failed

Slashdot - Sun, 06/25/2017 - 16:28
troublemaker_23 quotes ITWire: A developer who worked with the Ubuntu Phone project has outlined the reasons for its failure, painting a picture of confusion, poor communication and lack of technical and marketing foresight. Simon Raffeiner stopped working with the project in mid-2016, about 10 months before Canonical owner Mark Shuttleworth announced that development of the phone and the tablet were being stopped. Raffeiner says, for example, that "despite so many bugs being present, developers were not concentrating on fixing them, but rather on adding support for more devices." But he says he doesn't regret the time he spent on the project -- though now he spends his free time "traveling the world, taking photographs and creating bad card games, bad comics and bad games." "Please note that this post does not apply to the UBPorts project, which continues to work on the phone operating system, Unity 8 and other components."

How A Contractor Exploited A Vulnerability In The FCC Website

Slashdot - Sun, 06/25/2017 - 15:24
RendonWI writes: A Wisconsin wireless contractor discovered a flaw in the FCC's Antenna Structure Registration (ASR) database, and changed the ownership of more than 40 towers from multiple carriers and tower owners into his company's name during the past five months without the rightful owners being notified by the agency, according to FCC documents and sources knowledgeable of the illegal transfers. Sprint, AT&T and key tower companies were targeted in the wide-ranging thefts... Changing ASR ownership is an easy process by applying online for an FCC Registration Number (FRN) which is instantly granted whether the factual or inaccurate information is provided. Then, once logged in, an FRN holder can submit a form stating that they are the new owner of any or multiple structures in the database. As soon as it is submitted, the change is immediately reflected in the ASR.

What Happens When Geoengineers 'Hack The Planet'?

Slashdot - Sun, 06/25/2017 - 13:14
Dan Drollette shares an article by an Oxford physics professor who's concerned about the popularity of radical new proposals to fight global warming. The Christian Science Monitor wonders if it's time to re-engineer our climate. MIT's Technology Review basically thinks the answer is "yes," having described it earlier as "cheap and easy." The Atlantic seems quite smitten with Economist writer Oliver Morton's vision of remaking the planet, which geoengineering booster Jane Long breathlessly called "geopoetry." The idea received recent coverage (much of it favorable) by New Scientist, NBC, and in TED talks; I myself have recently participated in an NPR panel discussion on the subject... But what has really catapulted the idea into the public eye is Harvard's reckless plan for a privately-funded field trial testing some of the key elements needed... Proceeding to field experimentation crosses a thin red line beyond which lies the slippery slope down to ever-larger field trials and ultimately deployment. Harvard's experiment -- which is partially funded by Bill Gates -- is "subject to no governance save what Harvard chooses to impose upon itself," according to the article. The experiment involves "putting something in the atmosphere to reflect more sunlight back out into space," which the article warns will create "enduring" effects -- and require humanity to commit to maintaining the same atmospheric conditions forever.

Does US Have Right To Data On Overseas Servers? We're About To Find Out

Slashdot - Sun, 06/25/2017 - 09:10
Long-time Slashdot reader quotes Ars Technica: The Justice Department on Friday petitioned the US Supreme Court to step into an international legal thicket, one that asks whether US search warrants extend to data stored on foreign servers. The US government says it has the legal right, with a valid court warrant, to reach into the world's servers with the assistance of the tech sector, no matter where the data is stored. The request for Supreme Court intervention concerns a 4-year-old legal battle between Microsoft and the US government over data stored on Dublin, Ireland servers. The US government has a valid warrant for the e-mail as part of a drug investigation. Microsoft balked at the warrant, and convinced a federal appeals court that US law does not apply to foreign data. According to the article, the U.S. government told the court that national security was at risk.

Account Registrations Enable 'Password Reset Man In The Middle' Attacks

Slashdot - Sun, 06/25/2017 - 06:06
"Attackers that have set up a malicious site can use users' account registration process to successfully perform a password reset process on a number of popular websites and messaging mobile applications, researchers have demonstrated." Orome1 quotes Help Net Security: The Password Reset Man in the Middle attack exploits the similarity of the registration and password reset processes. To launch such an attack, the attacker only needs to control a website. To entice victims to make an account on the malicious website, the attacker can offer free access to a wanted resource. Once the user initiates the account registration process by entering their email address, the attacker can use that information to initiate a password reset process on another website that uses that piece of information as the username (e.g. Google, YouTube, Amazon, Twitter, LinkedIn, PayPal, and so on). Every request for input from that site is forwarded to the potential victim, and then his or her answers forwarded back to that particular site. Interestingly, it can also beat two-factor authentication -- since the targeted user will still input the phone code into the man-in-the-middle site.

Germany Cracks Down On Illegal Speech On Social Media.

Slashdot - Sun, 06/25/2017 - 03:02
ArmoredDragon writes: German police have raided 36 homes of people accused of using illegal speech on Facebook and Twitter. Much of it was aimed at political speech. According to the article, "Most of the raids concerned politically motivated right-wing incitement, according to the Federal Criminal Police Office, whose officers conducted home searches and interrogations. But the raids also targeted two people accused of left-wing extremist content, as well as one person accused of making threats or harassment based on someone's sexual orientation." This comes just as a new law is being debated that can fine social media platforms $53 million for not removing 70% of illegal speech (including political, defamatory, and hateful speech) within 24 hours of it being posted, which Facebook argues will make it obligatory for them to delete posts and ban users for speech that isn't clearly illegal.

Linus Explains What Surprises Him After 25 Years Of Linux

Slashdot - Sun, 06/25/2017 - 00:58
Linus Torvalds appeared in a new "fireside chat" with VMware Head of Open Source Dirk Hohndel. An anonymous reader writes: Linus explained what still surprises him about Linux development. "Code that I thought was stable continually gets improved. There are things we haven't touched for many years, then someone comes along and improves them or makes bug reports in something I thought no one used. We have new hardware, new features that are developed, but after 25 years, we still have old, very basic things that people care about and still improve... Our processes have not only worked for 25 years, we still have a very strong maintainer group... And as these maintainers get older and fatter, we have new people coming in." Linus also says he's surprised by the widespread popularity of Git. "I expected it to be limited mostly to the kernel -- as it's tailored to what we do... In certain circles, Git is more well known than Linux." And he also shares advice if you want to get started as an open source developer. "I'm not sure my example is the right thing for people to follow. There are a ton of open source projects and, if you are a beginning programmer, find something you're interested in that you can follow for more than just a few weeks... If you can be part of a community and set up patches, it's not just about the coding, but about the social aspect of open source. You make connections and improve yourself as a programmer." Linus also says that "I really like what I'm doing. I like waking up and having a job that is technically interesting and challenging without being too stressful so I can do it for long stretches; something where I feel I am making a real difference and doing something meaningful not just for me."

State Legislators Want Surveillance Cameras To Catch Uninsured Drivers

Slashdot - Sat, 06/24/2017 - 23:54
An anonymous reader quotes Ars Technica: A Rhode Island legislative committee has approved a bill that would greatly expand the surveillance state through the deployment of license plate readers. For the first time in the US, these devices would be attached along Rhode Island highways and roads for the stated purpose of catching uninsured motorists from any state... The legislation spells out that the contractor for the project would get 50 percent of the fines paid by uninsured motorists ensnared under the program. The state and the contractor would each earn an estimated $15 million annually. Fines are as high as $120. Many police departments nationwide are using surveillance cameras tacked onto traffic poles and police vehicles to catch traffic violators and criminal suspects. The proceeds from traffic fines usually are divvied up with contractors. But according to the Rhode Island lawmaker sponsoring this legislation, it's time to put surveillance cameras to a new purpose -- fining uninsured motorists.

Survey Says: Raspberry Pi Still Rules, But X86 SBCs Have Made Gains

Slashdot - Sat, 06/24/2017 - 22:50
DeviceGuru writes: Results from LinuxGizmos.com's annual hacker-friendly single board computer survey are in, and not surprisingly, the Raspberry Pi 3 is the most desired maker SBC by a 4-to-1 margin. In other trends: x86 SBCs and Linux/Arduino hybrids have trended upwards. The site's popular hacker SBC survey polled 1,705 survey respondents and asked for their first, second, and third favorite SBCs from a curated list of 98 community oriented, Linux- and Android-capable boards. Spreadsheets comparing all 98 SBCs' specs and listing their survey vote tallies are available in freely downloadable Google Docs. Other interesting findings: "A Raspberry Pi SBC has won in all four of our annual surveys, but never by such a high margin."The second-highest ranked board -- behind the Raspberry Pi 3 -- was the Raspberry Pi Zero W."The Raspberry Pi's success came despite the fact that it offers some of the weakest open source hardware support in terms of open specifications. This, however, matches up with our survey responses about buying criteria, which ranks open source software support and community over open hardware support.""Despite the accelerating Raspberry Pi juggernaut, there's still plenty of experimentation going on with new board models, and to a lesser extent, new board projects."

Should Your Company Switch To Microservices?

Slashdot - Sat, 06/24/2017 - 21:46
Walmart Canada claims that it was microservices that allowed them to replace hardware with virtual servers, reducing costs by somewhere between 20 and 50 percent. Now Slashdot reader snydeq shares an article by a senior systems automation engineer arguing that a microservices approach "offers increased modularity, making applications easier to develop, test, deploy, and, more importantly, change and maintain." The article touts things like cost savings and flexibility for multiple device types, suggesting microservices offer increased resilience and improved scalabiity (not to mention easier debugging and a faster time to market with an incremental development model). But it also warns that organizations need the resources to deploy the new microservices quicky (and the necessary server) -- along with the ability to test and monitor them for database errors, network latency, caching issues and ongoing availability. "You must embrace devops culture," argues the article, adding that "designing for failure is essential... In a traditional setting, developers are focused on features and functionalities, and the operations team is on the hook for production challenges. In devops, everyone is responsible for service provisioning -- and failure." The original submission ends with a question for Slashdot reader. "What cautions do you have to offer for folks considering tapping microservices for their next application?"

Researcher Finds Critical OpenVPN Bug Using Fuzzing

Slashdot - Sat, 06/24/2017 - 20:42
"Guido Vranken recently published 4 security vulnerabilities in OpenVPN on his personal blog," writes long-time Slashdot reader randomErr -- one of which was a critical remote execution bug. Though patches have been now released, there's a lesson to be learned about the importance of fuzzing -- bug testing with large amounts of random data -- Guido Vranken writes: Most of these issues were found through fuzzing. I hate admitting it, but...the arcane art of reviewing code manually, acquired through grueling practice, are dwarfed by the fuzzer in one fell swoop; the mortal's mind can only retain and comprehend so much information at a time, and for programs that perform long cycles of complex, deeply nested operations it is simply not feasible to expect a human to perform an encompassing and reliable verification. ZDNet adds that "OpenVPN's audits, carried out over the past two years, missed these major flaws. While a handful of other bugs are found, perhaps OpenVPN should consider adding fuzzing to their internal security analysis in the future." Guido adds on his blog, "This was a labor of love. Nobody paid me to do this. If you appreciate this effort, please donate BTC..."

UK Parliament Emails Closed After 'Sustained And Determined' Cyber-Attack

Slashdot - Sat, 06/24/2017 - 19:38
An anonymous reader quotes the Guardian: Parliament has been hit by a "sustained and determined" cyber-attack by hackers attempting to gain access to MPs' and their staffers' email accounts. Both houses of parliament were targeted on Friday in an attack that sought to gain access to accounts protected by weak passwords... The estate's digital services team said they had made changes to accounts to block out the hackers, and that the changes could mean staff were unable to access their emails... The international trade secretary, Liam Fox, told ITV News the attack was a "warning to everyone we need more security and better passwords. You wouldn't leave your door open at night." In an interview with the BBC, he added: "We know that there are regular attacks by hackers attempting to get passwords. We have seen reports in the last few days of even Cabinet ministers' passwords being for sale online. We know that our public services are attacked, so it is not at all surprising that there should be an attempt to hack into parliamentary emails." One member of Parliament posted on Twitter "Sorry, no parliamentary email access today â" we're under cyber-attack from Kim Jong-un, Putin or a kid in his mom's basement or something." He added later, "I'm off to the pub."

'Stack Clash' Linux Flaw Enables Root Access. Patch Now

Slashdot - Sat, 06/24/2017 - 18:34
msm1267 writes: Linux, BSD, Solaris and other open source systems are vulnerable to a local privilege escalation vulnerability known as Stack Clash that allows an attacker to execute code at root. Major Linux and open source distributors made patches available Monday, and systems running Linux, OpenBSD, NetBSD, FreeBSD or Solaris on i386 or amd64 hardware should be updated soon. The risk presented by this flaw, CVE-2017-1000364, becomes elevated especially if attackers are already present on a vulnerable system. They would now be able to chain this vulnerability with other critical issues, including the recently addressed Sudo vulnerability, and then run arbitrary code with the highest privileges, said researchers at Qualys who discovered the vulnerability.

Former Slashdot Contributor Jon Katz Believes He Can Talk To Animals

Slashdot - Sat, 06/24/2017 - 17:34
Long-time Slashdot reader destinyland got a surprise when he visited his local bookstore: Jon Katz turns 70 this August, and he's published a new book called Talking to Animals: How You Can Understand Animals and They Can Understand You. Katz was a former newspaper reporter (and a contributing editor to Rolling Stone) who wrote for HotWired, the first online presence for Wired magazine in the mid-1990s, before becoming a controversial contributor to Slashdot during the site's early days. Katz left Manhattan in the 1990s to live on a farm "surrounded by dogs, cats, sheep, horses, cows, goats, and chickens," according to the book's description, an experience he writes about on his blog. His new book promises that Katz now "marshals his experience to offer us a deeper insight into animals and the tools needed for effectively communicating with them."

Phoronix is hosting a 2017 Linux Laptop Survey. From their site: While Linux laptop compatibility is much better than where it was years ago, it's still not too uncommon to run into display/hybrid issues, shorter battery life under Linux than Windows or macOS, touchpad problems, and other occasional compatibility/performance shortcomings. So we've established this Linux Laptop Survey in conjunction with Linux stakeholders to hopefully gather more feedback that will be useful to many different parties... The survey will be online until July 6th, after which the results will be publicly available, and will determine the most popular brands, distros, screen sizes, and GPUs, as well as common pain points and popular price points. And one particularly interestng question asks respondents what they'd like to see in a "dream Linux laptop."

The People GoFundMe Leaves Behind

Slashdot - Sat, 06/24/2017 - 15:00
citadrianne shares a report from The Outline: President Donald Trump's proposed budget seeks to slash $54 billion from social services including programs like Medicaid and Meals on Wheels. As these resources dry up, crowdfunding websites will further entrench themselves as extra-governmental welfare providers in order to fill the gap. For a lucky few, these sites are a lifeline. For most people, they are worthless. Crowdfunding's fatal flaw is that not every campaign ends up getting the money it needs. A recent study published in the journal Social Science & Medicine found that more than 90 percent of GoFundMe campaigns never meet their goal. For every crowdfunding success story, there are hundreds of failures. "As many happy stories as there are in charitable crowdfunding, there are a lot of really worthy causes when you browse these platforms that nobody has given a cent to," Rob Gleasure, professor at the business school of the National University of Ireland, Cork told The Outline. "People haven't come across them." Feller and Gleasure's report highlighted how fickle crowdfunding can be. Of all the Razoo campaigns started in 2013, they found, more than a third didn't receive any funding at all. According to their report, donors are more likely to give to campaigns that feature lots of pictures and accompanying text.
