The Physics Of A Personal Injury

needhelp1800 (3663221) writes | about half an hour ago


needhelp1800 (3663221) writes "The most common question that is usually asked first in a personal injury case is “How is it that I got hurt?”. Many times, the answer is not always easily apparent, especially in a relatively low impact situation. As personal injury experts at 1-800-NeedHelp, this is usually the most contentious matter that often comes up when we assist in resolving a claim for our clients. A great way to combat the arguments of the insurance industry regarding low impact collisions is to work with and educate the adjuster about the basic physics of human physiology."

The ultimate goal of the NSA is total population control

stephendavion (2872091) writes | 49 minutes ago


stephendavion (2872091) writes "William Binney is one of the highest-level whistleblowers to ever emerge from the NSA. He was a leading code-breaker against the Soviet Union during the Cold War but resigned soon after September 11, disgusted by Washington’s move towards mass surveillance.

On 5 July he spoke at a conference in London organised by the Centre for Investigative Journalism and revealed the extent of the surveillance programs unleashed by the Bush and Obama administrations.

“At least 80% of fibre-optic cables globally go via the US”, Binney said. “This is no accident and allows the US to view all communication coming in. At least 80% of all audio calls, not just metadata, are recorded and stored in the US. The NSA lies about what it stores.”"

Google: You Can't Handle the Brazil Defeat Truth!

theodp (442580) writes | 1 hour ago


theodp (442580) writes "After Brazil's dramatic World Cup defeat by Germany, writes NPR's Aarti Shahani, Google's experimental newsroom focused on search trends that didn't rub salt in Brazil's wounds, choosing to not publish a single trend on Brazilian search terms. Copywriter Tessa Hewson said they were just too negative. "We might try and wait until we can do a slightly more upbeat trend." It's a decision that puzzles Shahani, but producer Sam Clohesy explained, "a negative story about Brazil won't necessarily get a lot of traction in social." In old-school newsrooms, if it bleeds, it leads. But because this new newsroom is focused on getting content onto everyone's smartphone, marketing expert Rakesh Agrawal says, editors may have another bias: to comb through the big data in search of happy thoughts."

Google, Dropbox, And Others Forge Patent 'Arms Control Pact'

jfruh (300774) writes | yesterday


jfruh (300774) writes "Patent trolling is a serious irritatnt and financial drain on many big tech companies — but those same companies can't guarantee that their own future management won't sell the patents they own to a 'non-practicing entity', especially in the case of sale or bankruptcy. That's why a number of tech giants, including Google and Dropbox, have formed the 'License or Tranfer Network,' in which a patent will automatically be licensed to everyone else in the network in the event that it's sold to a third party."

Peer Review Ring Broken - 60 Articles Retracted

blackbeak (1227080) writes | 8 hours ago


blackbeak (1227080) writes "The Washington Post reports that the Journal of Vibration and Control's review system was hijacked by a ring of reviewers. 60 articles have been retracted as a result. If a relatively nonpolitical field like JVC covers is subject to this kind of nonsense, what might be lurking behind peer reviews in the pharmaceutical or petroleum fields? Maybe non peers should be partnered with peers to do the reviewing."

Child Thought to Be Cured of HIV Relapses, Tests Positive Again

Anonymous Coward writes | 5 hours ago


An anonymous reader writes "The Mississippi child, who was born with HIV passed from her mother, received HIV treatment for 18 months after her birth. In the course of over two years after the treatment, her blood indicated no trace of the virus or of HIV-specific antibodies, leading many to hope that she may have been cured completely. Earlier this month, however, the virus was detected again. Nearly 4 years old, the child is once more being given HIV treatment, and scientists are trying to figure out how she could have gone so long before relapsing."

Layoffs coming at Microsoft?

whoever57 (658626) writes "Shaun Nichols at The Register interpets Satya Nadella's open letter as "prepare for layoffs". The letter suggests radical changes are coming to Microsoft and, combined with duplication of functions because of the Nokia handset business acquisition, he thinks that layoffs are highly likely. Wes Miller, research vice-president at Directions on Microsoft, says that Microsoft is shifting from the Windows-everywhere approach, towards supporting productivity applications on different platforms. More details will be forthcoming from Microsoft on July 22."

Where will we all be in 100 billion years?

StartsWithABang (3485481) writes | 6 hours ago


StartsWithABang (3485481) writes "We've come a long way in the Universe to get to where we are: we had to form protons and neutrons, atomic nuclei, neutral atoms, many generations of stars and galaxies and clusters on the largest scales to create the Universe we see today. And yet, the 13.8 billion years that have passed since our Big Bang is just a drop in the bucket compared to what's coming in our future. How would we perceive our Universe differently if we, instead, came about in this Universe 100 billion years ago? The differences are shocking, but maybe even more shocking is how much we'd be unable to know about our cosmic origins!"

Unattended maintenance windows

grahamsaa (1287732) writes | 7 hours ago


grahamsaa (1287732) writes "Like many others in IT, I sometimes have to do server maintenance at unfortunate times. 6AM is the norm for us, but in some cases we're expected to do it as early as 2AM, which isn't exactly optimal. I understand that critical services can't be taken down during business hours, and most of our products are used 24 hours a day, but for some things it seems like it would be possible to automate maintenance (and downtime).

I have a maintenance window at about 5AM tomorrow. It's fairly simple — upgrade CentOS, remove a package, install a package, reboot. Downtime shouldn't be more than 5 minutes. While I don't think it would be wise to automate this window, I think with sufficient testing we might be able to automate future maintenance windows so I or someone else can sleep in. Aside from the benefit of getting a bit more sleep, automating this kind of thing means that it can be written, reviewed and tested well in advance. Of course, if something goes horribly wrong having a live body keeping watch is probably helpful. That said, we do have people on call 24/7 and they could probably respond capably in an emergency. Have any of you tried to do something like this? What's your experience been like?"

NNSA Reveals Supercomputer Set to Take Over China's Top System

Anonymous Coward writes | 8 hours ago


An anonymous reader writes "The National Nuclear Security Administration just unleashed news that it's invested close to $200 million for a new system so powerful, it could topple the far-dominant Chinese supercomputer, called Tianhe-2. Powered by the next generation Haswell processors and the upcoming, still mysterious self-hosted Intel Knight's Landing chips, the machine might be capable of close to 100 petaflops, at least if my math is correct given the node and rack figures leaked here."

SpaceX Wins FAA Permission to Build a Spaceport in Texas

Jason Koebler (3528235) writes | 13 hours ago


Jason Koebler (3528235) writes "SpaceX just got approval from the Federal Aviation Administration to build a 56.5-acre spaceport along the Gulf of Mexico on the Texas-Mexico border—a huge step toward actually making the spaceport a reality.
Wednesday, the FAA, which handles all commercial space launch permitting in the United States, issued what's known as a "Record of Decision" that suggests the agency would allow the company to launch 10 Falcon 9 rockets and two Falcon Heavy rockets per year out of the spaceport, through at least 2025."

Hints of Life's Start Found in a Giant Virus

Anonymous Coward writes | 12 hours ago


An anonymous reader writes "In the world of microbes, viruses are small — notoriously small. Pithovirus is not. The largest virus ever discovered, pithovirus is more massive than even some bacteria. Most viruses copy themselves by hijacking their host’s molecular machinery. But pithovirus is much more independent, possessing some replication machinery of its own. Pithovirus’s relatively large number of genes also differentiated it from other viruses, which are often genetically simple — the smallest have a mere four genes. Pithovirus has around 500 genes, and some are used for complex tasks such as making proteins and repairing and replicating DNA. “It was so different from what we were taught about viruses,” Abergel said.

The stunning find, first revealed in March, isn’t just expanding scientists’ notions of what a virus can be. It is reframing the debate over the origins of life."
