Comment Why aren't 12V Lithium car batteries more popular? (Score 5, Interesting) 138

I've noticed that replacement lithium polymer battery packs for hybrid cars sell often sell for less than $1000 on eBay, while much smaller lithium based 12v batteries for conventional cars (with starter motors) often sell for more. As an example, here is a battery suitable for starting a small V8 that sells for $1600.00 http://www.jegs.com/i/Lithium-...

I would assume that it would be much easier to manufacture conventional 12v starter batteries in volume due to the ability to put them in many more different models of vehicles.

The ability to shave off 30+ lbs of weight from racecars would be enormous, so the demand is there, but why not the supply?

Submission + - Tinder and Grindr dating apps linked to more than 500 UK crimes (mirror.co.uk)

schwit1 writes: Data compiled by almost three-quarters of police forces across England and Wales listed 523 crimes from the past five years where official logs included the words Tinder or Grindr.

It comes after serial killer Stephen Port was jailed last month for the murders of four young men, including Daniel Whitworth, he met on gay websites and apps including Grindr. Lib Dem leader Tim Farron warned: “I worry that these shocking figures could just be the tip of the iceberg.”

Submission + - Firefox 52 Borrows One More Privacy Feature from the Tor Browser (bleepingcomputer.com)

An anonymous reader writes: Mozilla engineers have added a mechanism to Firefox 52 that prevents websites from fingerprinting users using system fonts. The user privacy protection system was borrowed from the Tor Browser, where a similar mechanism blocks websites from identifying users based on the fonts installed on their computers, only returning a list of "default fonts" per each OS.

While sabotaging system font queries won't stop user fingerprinting as a whole, this is just one of the latest privacy-related updates Mozilla has added to Firefox, taken from Tor. Back in July 2016, Mozilla engineers started the Tor Uplift project, which aims to improve Firefox's privacy features with the ones present in the Tor Browser.

Submission + - Robot lie detector being tested by Canada (phys.org)

schwit1 writes: What could possibly go wrong? Canada’s border police are currently testing a robot lie-detector that would be used to screen travelers and flag those whose answers it doesn’t like.

AVATAR is a kiosk, much like an airport check-in or grocery store self-checkout kiosk,” said San Diego State University management information systems professor Aaron Elkins. “However, this kiosk has a face on the screen that asks questions of travelers and can detect changes in physiology and behavior during the interview. The system can detect changes in the eyes, voice, gestures and posture to determine potential risk. It can even tell when you’re curling your toes.”

Here’s how it would work: Passengers would step up to the kiosk and be asked a series of questions such as, “Do you have fruits or vegetables in your luggage?” or “Are you carrying any weapons with you?” Eye-detection software and motion and pressure sensors would monitor the passengers as they answer the questions, looking for tell-tale physiological signs of lying or discomfort. The kiosk would also ask a series of innocuous questions to establish baseline measurements so people are just nervous about flying, for example, wouldn’t be unduly singled out.

Once the kiosk detected deception, they would flag those passengers for further scrutiny from human agents.

This Elkins guy fits perfectly the 1960s stereotype of the scientist who is so caught up with the coolness of his invention that he is completely oblivious to its moral and ethical short-comings. Sadly, he appears to be finding lots of governments interested in buying his product.

Submission + - GRIZZLY STEPPE: Technical report on DNC hack (nymag.com)

schwit1 writes: Following weeks of accusations and insinuations — and counterclaims and skepticism — about the role of the Russian government in this summer’s hack of the Democratic National Committee’s email (an attack given the evocative name “GRIZZLY STEPPE” by the Department of Homeland Security) a new joint report was published today by the DHS and FBI. The question is, does the new report actually clear anything up?

Submission + - Facebook Buys Data From Third-Party Brokers To Fill In User Profiles (ibtimes.com)

An anonymous reader writes: According to a report from ProPublica, the world’s largest social network knows far more about its users than just what they do online. What Facebook can’t glean from a user’s activity, it’s getting from third-party data brokers. ProPublica found the social network is purchasing additional information including personal income, where a person eats out and how many credit cards they keep. That data all comes separate from the unique identifiers that Facebook generates for its users based on interests and online behavior. A separate investigation by ProPublica in which the publication asked users to report categories of interest Facebook assigned to them generated more than 52,000 attributes. The data Facebook pays for from other brokers to round out user profiles isn’t disclosed by the company beyond a note that it gets information “from a few different sources.” Those sources, according to ProPublica, come from commercial data brokers who have access to information about people that isn’t linked directly to online behavior. The social network doesn’t disclose those sources because the information isn’t collected by Facebook and is publicly available. Facebook does provide a page in its help center that details how to get removed from the lists held by third-party data brokers. However, the process isn’t particularly easy. In the case of the Oracle-owned Datalogix, users who want off the list have to send a written request and a copy of a government-issued identification in the mail to Oracle’s chief privacy officer. Another data collecting service, Acxiom, requires users provide the last four digits of their social security number to see the information the company has gathered about them.

Comment Correlation between Antibiotics and Obesity? (Score 3, Interesting) 256

On a hunch I decided to see if there's a correlation between obesity and antibiotics (which are known to kill both the good and bad types of gut bacteria)

Here's a map showing antibiotic prescribing rates.

Here's a map showing obesity rates:

Correlation is not causation, but in my unprofessional opinion, these maps look eerily similar.
