This is not F1 (or NASCAR): High-End Hybrids Race In Texas 16

Ars Technica takes an in-depth look at some of the tech side of the hybrid racing circuit, in particular the World Endurance Championship . From the article: Hybrid systems are allowed to deploy between 2MJ and 8MJ of energy during a single lap of Le Mans, augmenting the power from an internal combustion engine. Energy can be recovered from up to two motor/generator units (MGUs); usually this means recapturing kinetic energy from the front and rear wheels under braking. To balance things out, cars that recover and deploy 8MJ carry less fuel, and the flow rate at which they can feed it to the engine decreases. Audi's R18, with its mix of turbo diesel and flywheel hybrid technology, was king of the hill for several years, but the hybrid systems were much less powerful. Last year, Toyota's gasoline V8 and supercapacitor-powered TS040 was the car to beat. But 2015 is the year of the Porsche 919 Hybrid. Porsche chose lithium-ion batteries to hybridize the 919's turbocharged gasoline V4, and this year is able to capture and deploy the full 8MJ (Toyota is in the 6MJ class and Audi 4MJ). The article spends more space on Audi's approach than the others, but offers a cool glimpse at all three of these companies' niches within the field, as represented at the Texas' Lone Star Le Mans.

Chrome AdBlock Joining Acceptable Ads Program (And Sold To Anonymous Company) 133

basscomm writes: Hot on the heels of the formation of the independent board to oversee "acceptable ads", users of the popular Chrome ad blocking extension, AdBlock, got notice that AdBlock is participating in the program, and that acceptable ads are being turned on by default. At the bottom of the announcement, buried in the fine print is word that AdBlock has been sold, but nobody will say to whom.

Ask Slashdot: Best Country For Secure Online Hosting? 58

An anonymous reader writes: I've recently discovered that my hosting company is sending all login credentials unencrypted, prompting me to change providers. Additionally, I'm finally being forced to put some of my personal media library (songs, photos, etc.) on-line for ready access (though for my personal consumption only) from multiple devices and locations... But I simply can't bring myself to trust any cloud-service provider. So while it's been partially asked before, it hasn't yet been answered: Which country has the best on-line personal privacy laws that would made it patently illegal for any actor, state, or otherwise, to access my information? And does anyone have a recommendation on which provider(s) are the best hosts for (legal) on-line storage there?

When Fraud Detection Shuts Down Credit Cards Inappropriately 181

reifman writes: On Sunday, Capital One declined a $280 travel reservation I charged at India-based ClearTrip.com and immediately shut off my card for all transactions until I contacted them by phone. It wasn't the first time that CapitalOne had shut off my card after a single suspect transaction. But, I'd actually purchased from ClearTrip.com using my CapitalOne card on two prior occasions. It was an example of very poor fraud detection and led me on a tour of their pathetic customer service. The banks want to cut their losses regardless of how it impacts their customers. Having had my own credit card suspended out of an abundance of caution on a different credit card issuer's part (for legitimate charges), but having recently had some widely known scam charges get accepted, the fraud protection algorithms that the credit companies use certainly seem inscrutable sometimes, and so do the surrounding practices about communicating with customers. How would you like it to work instead?

Stolen Patreon User Data Dumped On Internet 85

After the personal data breach at crowd-funding site Patreon reported a few days ago, there's some worse news: the information isn't just in limbo any more; Patreon reported Saturday that the compromised information has been leaked in the form of a massive data dump. (The slightly good news is that no credit card information was leaked.)

Submission Why It Was Easier to Be Skinny in the 1980s

schwit1 writes: A new study finds that people today who eat and exercise the same amount as people 20 years ago are still fatter.

A study published recently in the journal Obesity Research & Clinical Practice found that it's harder for adults today to maintain the same weight as those 20 to 30 years ago did, even at the same levels of food intake and exercise. The authors examined the dietary data of 36,400 Americans between 1971 and 2008 and the physical activity data of 14,419 people between 1988 and 2006. They grouped the data sets together by the amount of food and activity, age, and BMI.

They found a very surprising correlation: A given person, in 2006, eating the same amount of calories, taking in the same quantities of macronutrients like protein and fat, and exercising the same amount as a person of the same age did in 1988 would have a BMI that was about 2.3 points higher. In other words, people today are about 10 percent heavier than people were in the 1980s, even if they follow the exact same diet and exercise plans.

Vostochny Launch Building Built To the Wrong Size 66

schwit1 writes: The Russians have just discovered that their Soyuz 2 rocket does not fit in the building just finished at their new spaceport at Vostochny: "The cutting-edge facility was meant be ready for launches of Soyuz-2 rockets in December, but an unidentified space agency told the TASS news agency late Thursday that the rocket would not fit inside the assembly building where its parts are stacked and tested before launch. The building 'has been designed for a different modification of the Soyuz rocket,' the source said, according to news website Medusa, which picked up the story from TASS." The rocket had just been delivered to Vostochny for assembly, so this report, though unconfirmed at this time, fits well with current events.

Hour of Code Kicks Off In Chile With Dog Poop-Themed CS Tutorial 43

theodp writes: In an interesting contrast to the Disney princess-themed Hour of Code tutorial that 'taught President Obama to code' last December, Chile is kicking off its 2015 Hora del Codigo this week with a top-featured Blockly tutorial that teaches computer science by having kids drag-and-drop blocks of code to pick up dog poop. "Collect all the shit you have left your dog," reads the Google translated instructions for the final coding exercise. In its new video for the Hour of Code 2015 campaign, tech billionaire-backed Code.org notes that it's striving to reach 200 million schoolchildren worldwide by this December. Presumably towards that end, Code.org warns that it will penalize Computer Science tutorials that "work only in English."

Legionnaires' Bacteria Reemerges In Previously Disinfected Cooling Towers 84

schwit1 writes with the New York Times' unsettling report that 15 water-cooling towers in the Bronx that this week tested positive for Legionnaires' disease had been disinfected less than two months ago. From the NYT: After an outbreak of the disease killed 12 people in July and August in the South Bronx, the city required every building with cooling towers, a common source of the Legionella bacteria that cause the disease, to be cleaned within two weeks. ... [The] city found this week that bacteria had regrown in at least 15 towers that had been cleaned recently in the Morris Park section of the Bronx. The testing occurred after a fresh outbreak in that area that has killed one person and sickened at least 12, and spurred an order from health officials for the towers to be disinfected again.

'Legacy' London Car Hire Companies Lawyer Up Against Uber 164

An anonymous reader writes with The Stack's report that: The London Private Hire Car Association (LPHCA) has engaged a major firm of lawyers to present its case against Uber in the UK capital, citing lack of continuous insurance checks, Uber's tax avoidance practices and even 'loitering' Uber drivers as reasons to impose regulations which would eliminate Uber's competitive advantage in London. A lot of Londoners like to have that competition around, though.

Michigan Mammoth May Have Been Butchered By Humans 35

Forbes reports that a mammoth recently unearthed in rural Michigan includes evidence that the animal was butchered for food: From the article: A small stone that could potentially be a cutting tool was also found with the mammoth bones. To confirm that this animal was butchered by humans, researchers will examine the bones for cut marks that would indicate people were processing it for meat. A third piece of evidence is the organized way the neck vertebrae of the mammoth were found. "An animal doesn't just come apart naturally leaving a sequence of tightly articulated vertebrae like that," Fisher said, indicating that the animal would have had to have been moved by humans for paleontologists to find the bones laid out in such a fashion.

Apollo-Era Photos Now Up at NASA's Flickr Account, In High-Res 90

Submission Legionnaires' Bacteria Regrew in Bronx Cooling Towers That Were Disinfected->

schwit1 writes: The 15 water-cooling towers that were found to be contaminated this week amid a new cluster of Legionnaires' disease cases had been disinfected less than two months ago, New York City officials said on Thursday, raising questions about how successful the city can be in containing the disease.

After an outbreak of the disease killed 12 people in July and August in the South Bronx, the city required every building with cooling towers, a common source of the Legionella bacteria that cause the disease, to be cleaned within two weeks.

Despite that order, as well as new legislation mandating quarterly inspections of cooling towers, the city found this week that bacteria had regrown in at least 15 towers that had been cleaned recently in the Morris Park section of the Bronx. The testing occurred after a fresh outbreak in that area that has killed one person and sickened at least 12, and spurred an order from health officials for the towers to be disinfected again.

Inside the Spaceflight of 'The Martian' 85

benonemusic writes: Science writer Michael Greshko partnered with a team of scientists and engineers to explore the spacecraft and mission plans in The Martian (novel and movie), down to the rescue plan itself. Incorporating the help of Andy Weir, the novel's author, he comes up with a calendar of events for The Martian, explores the hazards of going back to save Mark Watney, and explains how a real world interplanetary spacecraft would pull off a rescue maneuver.
