Protons Collide At 13 TeV For the First Time At the LHC 31

Posted by Soulskill
from the go-big-or-go-home dept.
An anonymous reader writes to let everyone know the LHC has now smashed protons together at 13 TeV, the highest energy level yet achieved. They've posted the first images captured from the collisions, and explained the testing process as well. Jorg Wenninger of the LHC Operations team says, "When we start to bring the beams into collision at a new energy, they often miss each other. The beams are tiny – only about 20 microns in diameter at 6.5 TeV; more than 10 times smaller than at 450 GeV. So we have to scan around – adjusting the orbit of each beam until collision rates provided by the experiments tell us that they are colliding properly." Spokesperson Tiziano Camporesi adds, "The collisions at 13 TeV will allow us to further test all improvements that have been made to the trigger and reconstruction systems, and check the synchronisation of all the components of our detector."

How Cities: Skylines Beat SimCity At Its Own Game 44

An anonymous reader writes: Maxis, the studio behind SimCity, was shuttered earlier this year. Fortunately, another studio has taken up its mantle. The small team at Colossal Order has already won acclaim for city-builder game Cities: Skylines (and sold millions), earning a great reputation with the modding community by avoiding all the mistakes the last SimCity release made, such as enforced online/multiplayer. A new behind the scenes feature looks at how the game came about — it was not a response to SimCity, surprisingly — as well as what's next from the studio.

"We are planning to start another game project sometime soon," says Colossal CEO Mariina Hallikainen. "We definitely want to focus on old-school simulator games and definitely PC. PC, Mac and Linux, those are our 'thing.' But I think we're maybe going to do something a little bit different."

'Prisonized' Neighborhoods Make Recidivism More Likely 89

sciencehabit writes: One of the most important questions relating to incarceration and rehabilitation is how to discourage recidivism. After a prison stint, about half of convicts wind up back in the slammer within three years. But sociologist David Kirk noticed a pattern: convicts who moved away from their old neighborhood when released from prison had a much smaller recidivism rate. Kirk found that the concentration of former prisoners in a neighborhood had a dramatic effect on the likelihood of committing another offense (abstract). "So if an ex-con’s average chance of returning to prison after just 1 year was 22%—as it was in 2006—an additional new parolee in the neighborhood boosted that chance to nearly 25%. The numbers climb for each new parolee added. In some of the most affected neighborhoods—where five of every thousand residents were recent parolees—nearly 35% were back behind bars within a year of getting out." The rates stayed consistent even when controlling for chronic poverty and other neighborhood characteristics.

A Conversation with Druva Co-Founder Jaspreet Singh (Video) 30

Posted by Roblimo
from the doo-wop-is-now-de-dupe dept.
This was originally going to be an interview about the state of enterprise-level backup software in an increasingly edge computing-focused world, but we rapidly drifted into talking about how Druva started in Pune (near Bangalore) and ended up moving to Silicon Valley. We hear plenty about American software companies moving to India, but not a lot about Indian software companies moving here. Druva had good reasons for the move, the chief one being a financing deal with Sequoia Capital. Aside from that, though, Jaspreet says the talent pool -- not just developers but software marketing people and other important staffers -- is more concentrated in Silicon Valley than almost anywhere else in the world. 'It's like Hollywood for geeks,' Jaspreet says. This doesn't mean business is necessarily easy in the USA: Jaspreet ended up laying off his entire staff. Twice. And he made other mistakes as a young, new CEO bringing a company to life in a crowded field.

Those mistakes, which Jaspreet shares freely with us, are like a business school 'Start-Up Pitfalls' class. You may never want to do your own startup, but if you're a developer or otherwise involved with the software industry, there's a good chance that you'll have a chance to work for one at some point. And if you have that chance, you'll be glad you watched this video (or read the transcript) before you take the startup plunge.

Nerval's Lobster writes: Want more people to program? Encourage them to play more video games, at least according to Facebook CEO Mark Zuckerberg. In an online Q&A, Zuckerberg suggested that a lifetime spent playing video games could prep kids and young adults for careers as programmers. "I actually think giving people the opportunity to play around with different stuff is one of the best things you can do," he told the audience. "I definitely would not have gotten into programming if I hadn't played games as a kid." A handful of games, most notably Minecraft, already have a reputation for encouraging kids to not only think analytically, but also modify the gaming environment — the first steps toward actually wrestling with code.

jones_supa writes: After lots of work by Chrome for Android team and a huge change, Chrome for Android is now almost entirely open source, a Google engineer announced in Reddit. Over 100,000 lines of code, including the Chrome's entire user interface layer, has been made public, allowing anyone with the inclination to do so to look at, modify, and build the browser from source. Licensing restrictions prevent certain media codecs, plugins and Google service features form being included, hence the "almost." This is on par with the open source Chromium browser that is available on the desktop.

sciencehabit writes: The gates at American prisons can seem like revolving doors. People come in, do their time, and—within 3 years—half are back behind bars, according to U.S. Department of Justice statistics. Now, a scientist says he has nailed down one potential risk factor. An intriguing natural experiment that followed ex-cons displaced by Hurricane Katrina suggests that when former prisoners wind up moving to the same neighborhood, they are more likely to return to a life of crime.

The Body Cam Hacker Who Schooled the Police 134

Posted by Soulskill
from the watching-the-watchers dept.
New submitter Cuillere writes: In the fall of 2014, a hacker demanded the Seattle Police Department release all of their body and dash cam video footage, prompting chaos within the institution. Although it was a legal request per Washington state's disclosure laws, Seattle's PD wasn't prepared to handle the repercussions of divulging such sensitive material — and so much of it. The request involved 360 TB of data spread across 1.6 million recordings over 6 years. All recordings had to be manually reviewed and redacted to cut out "children, medical or mental health incidents, confidential informants, or victims or bystanders who did not want to be recorded," so fulfilling the request was simply not within the department's capabilities. Thus, they took a different strategy: they hired the hacker and put him to work on developing an automated redaction system. "Their vision is of an officer simply docking her body cam at the end of a shift. The footage would then be automatically uploaded to storage, either locally or in the cloud, over-redacted for privacy and posted online for everyone to see within a day."

Asteroid Risk Greatly Overestimated By Almost Everyone 202

Posted by Soulskill
from the but-my-asteroid-insurance-business-is-thriving dept.
StartsWithABang writes: When it comes to risk assessment, there's one type that humans are notoriously bad at: the very low-frequency but high-consequence risks and rewards. It's why so many of us are so eager to play the lottery, and simultaneously why we're catastrophically afraid of ebola and plane crashes, when we're far more likely to die from something mundane, like getting hit by a truck. One of the examples where science and this type of fear-based fallacy intersect is the science of asteroid strikes. With all we know about asteroids today, here's the actual risk to humanity, and it's much lower than anyone cares to admit.

+ - Neural implants let paralyzed man take a drink->

Submitted by mpicpp
mpicpp writes: Erik Sorto was shot in the back 13 years ago and paralyzed from the neck down. Yet recently the father of two lifted a bottle of beer to his lips and gave himself a drink, even though he can’t move his arms or legs.

Mr. Sorto, 34, picked up his drink with a robotic arm controlled by his thoughts. Two silicon chips in his brain read his intentions and channeled them via wires to the prosthetic arm on a nearby table. The team that developed the experimental implant, led by researchers at the California Institute of Technology, reported their work Thursday in the journal Science.

“That was amazing,” Mr. Sorto said. “I was waiting for that for 13 years, to drink a beer by myself.”

Mr. Sorto’s neural implant is the latest in a series of prosthetic devices that promise one day to restore smooth, almost natural movement to those who have lost the use of their limbs through disease or injury, by tapping directly into the signals generated by the brain.

For years, laboratories at Brown University, Duke University and Caltech, among others, have experimented with brain-controlled prosthetics. Those devices include wireless implants able to relay rudimentary mental commands, mind-controlled robotic leg braces, and sensors that add a sense of touch to robotic hands. In 2012, University of Pittsburgh researchers demonstrated a brain implant that allowed a paralyzed woman to feed herself a chocolate bar using a robot arm.

New Class of "Non-Joulian" Magnets Change Volume In Magnetic Field 30

Posted by Soulskill
from the polarizing-research dept.
Zothecula notes an announcement from the University of Maryland saying they have developed a new class of magnets, called "Non-Joulian" magnets, which physically expand in the presence of a magnetic field. "In the 1840s, physicist James Prescott Joule discovered that iron-based magnetic materials changed their shape but not their volume when placed in a magnetic field. This phenomenon is referred to as "Joule Magnetostriction," and since its discovery 175 years ago, all magnets have been characterized on this basis." Another significant property of these new magnets is that they can harvest or convert energy with very little waste heat (abstract). The magnets are created when thermally-treated, iron-based alloys are heated in a furnace, then rapidly cooled. When they reach room temperature, they have an odd, almost cellular shape on the microscopic level. The researchers say the magnets have numerous applications for energy-efficient sensors and actuators.

Adult Dating Site Hack Reveals Users' Sexual Preference, Extramarital Affairs 162

Posted by Soulskill
from the another-day,-another-breach dept.
An anonymous reader notes this report from Channel 4 News that Adult FriendFinder, one of the largest dating sites in the world, has suffered a database breach that revealed personal information for 3.9 million of its users. The leaked data includes email addresses, IP addresses, birth dates, postal codes, sexual preferences, and information indicating which of them are seeking extramarital affairs. There even seems to be data from accounts that were supposedly deleted. Channel 4 saw evidence that there were plans for a spam campaign against these users, and others are worried that a blackmail campaign will follow. "Where you've got names, dates of birth, ZIP codes, then that provides an opportunity to actually target specific individuals whether they be in government or healthcare for example, so you can profile that person and send more targeted blackmail-type emails," said cybercrime specialist Charlie McMurdy.
