Navy Guilty of Illegally Broad Online Searches: Child Porn Conviction Overturned

slashdot.org - dg, 14/09/2014 - 21:24
An anonymous reader writes In a 2-1 decision, the 9th Circuit Court ruled that Navy investigators regularly run illegally broad online surveillance operations that cross the line of military enforcement and civilian law. The findings overturned the conviction of Michael Dreyer for distributing child pornography. The illegal material was found by NCIS agent Steve Logan searching for "any computers located in Washington state sharing known child pornography on the Gnutella file-sharing network." The ruling reads in part: "Agent Logan's search did not meet the required limitation. He surveyed the entire state of Washington for computers sharing child pornography. His initial search was not limited to United States military or government computers, and, as the government acknowledged, Agent Logan had no idea whether the computers searched belonged to someone with any "affiliation with the military at all." Instead, it was his "standard practice to monitor all computers in a geographic area," here, every computer in the state of Washington. The record here demonstrates that Agent Logan and other NCIS agents routinely carry out broad surveillance activities that violate the restrictions on military enforcement of civilian law. Agent Logan testified that it was his standard practice to "monitor any computer IP address within a specific geographic location," not just those "specific to US military only, or US government computers." He did not try to isolate military service members within a geographic area. He appeared to believe that these overly broad investigations were permissible, because he was a "U.S. federal agent" and so could investigate violations of either the Uniform Code of Military Justice or federal law."

Solar Powered Technology Enhances Oil Recovery

slashdot.org - dg, 14/09/2014 - 20:11
mdsolar writes with this story of a company that uses solar energy to recover crude oil. Royal Dutch Shell has teamed with a sovereign investment fund from Oman to invest $53 million in a company that manufactures solar power equipment designed for increasing oil production. Glasspoint Solar Inc. installs aluminum mirrors near oil fields that concentrate solar radiation on insulated tubes containing water. The steam generated from heating the water is injected into oil fields to recover heavy crude oil. This concept of enhanced oil recovery. involves high pressure injection of hot fluids to recover heavy crude oil. The use of renewable energy like solar power makes great economic sense, as the fuel cost associated with this enhanced oil recovery technology is practically zero. Shell hopes to employ this technology in its oil fields in Oman. The company hopes to reduce greenhouse gas emissions associated with enhanced oil recovery operations. A large-scale successful implementation of this technology could be a game changer for major consumers like India and the U.S.. Both have substantial oil reserves, but are unable to tap them due to high costs involved in heavy oil recovery.

Sapphire Glass Didn't Pass iPhone Drop Test According to Reports

slashdot.org - dg, 14/09/2014 - 19:00
SternisheFan notes reports about why Apple didn't use sapphire glass screens in the latest iPhones as many expected. Sapphire screens were part of the iPhone 6 design until the glass repeatedly cracked during standard drop tests conducted by Apple suppliers. So Apple abandoned its sapphire plans before the iPhone 6 product launch September 9. VentureBeat has learned that recent supplier channel checks by an IDC analyst yielded several reports of the sapphire failures and Apple's decision against using the glass material. As we heard on Tuesday in Cupertino, both the iPhone 6 and the larger iPhone 6 Plus will ship with screens made of "ion-strengthened" glass. This was apparently Apple's second choice. IDC analyst Danielle Levitas says it isn't clear when exactly the drop-test failures took place, or when Apple abandoned plans for sapphire-screened iPhones. She says the poor drop-test results, combined with the relative high cost of sapphire glass, could have made plans to ship sapphire glass phones too risky. One researcher who covers GT Advanced Technologies, the company that was to produce the glass for the iPhone 6, wrote in a research note earlier this week that plans for the sapphire screens were cancelled in August, just weeks before the September 9 launch. The new Apple Watches (except the "Sport" version) do use sapphire for their screens. Levitas believes that the glass for the smaller 1.5-inch and 1.7-inch watch screens was less likely to break in drop tests.

KDevelop 4.7.0 Released

slashdot.org - dg, 14/09/2014 - 17:50
KDE Community (3396057) writes "KDevelop team is proud to announce the final release of KDevelop 4.7.0. This release is special, as it marks the end of the KDE4 era for us. As such, KDevelop 4.7.0 comes with a long-term stability guarantee. The CMake support was improved and extended to ensure that all idioms needed for KF5 development are available. The unit test support UI was polished and several bugs fixed. In the same direction, some noteworthy issues with the QtHelp integration were addressed. KDevelop's PHP language support now handles namespaces better and can understand traits aliases. Furthermore, some first fruits of the Google summer of code projects are included in this release. These changes pave the path toward better support for cross compile toolchains. Feature-wise, KDevelop now officially supports the Bazaar (bzr) version control system. On the performance front, it was possible to greatly reduce the memory footprint when loading large projects with several thousand files in KDevelop. Additionally, the startup should now be much faster."

School Installs Biometric Fingerprint System For Cafeteria

slashdot.org - dg, 14/09/2014 - 16:44
An anonymous reader writes with news about a school in England that has introduced a cashless cafeteria system that is raising some privacy concerns among some. Stourbridge students will soon be able to pay for their lunch without searching their pockets for change. Redhill School has spent £20,000 updating its dining facilities and introducing a cashless catering system. The system will allow parents to deposit funds into students catering accounts, to be debited by the pupil's biometric fingerprint scan at the point of sale. Headteacher Stephen Dunster said: "The benefits are that pupils are less likely to lose cash, parents know their children are using their dinner money to buy nutritious food and there will also be a system to alert staff if students are purchasing food that they may be allergic to."

Original 11' Star Trek Enterprise</em> Model Being Restored Again

slashdot.org - dg, 14/09/2014 - 14:36
NormalVisual (565491) writes The original 11-foot U.S.S. Enterprise studio model from the original series has gone back into the shop again. The Smithsonian owns the model and has had it on display in a gift shop at the National Air and Space Museum for the last 13 years, but will be placed on display in the Boeing Milestones of Flight Hall in 2016, to coincide with the museum's 40th anniversary. In the meantime, the model will be undergoing its fourth restoration to address a number of issues. The last restoration in 1991 was performed by Ed Miarecki, a professional modelmaker well known for his work in "Star Trek: The Next Generation", as well as films such as "Event Horizon". This previous restoration had Trek fans up in arms owing to the paint job, which many feel doesn't represent the way the model looked originally. Hopefully this next restoration will bring her back to her former glory.

High School Student Builds Gun That Unlocks With Your Fingerprint

slashdot.org - dg, 14/09/2014 - 13:28
An anonymous reader writes: Kai Kloepfer is a 17-year-old high school student from Colorado who just won the Smart Tech for Firearms Challenge. Kloepfer designed and built a smart gun that will only unlock and fire for users who supply the proper fingerprints. "The gun works by creating a user ID and locking in the fingerprint of each user allowed to use the gun. The gun will only unlock with the unique fingerprint of those who have already permission to access the gun. ... According to him, all user data is kept right on the gun and nothing is uploaded anywhere else so it would be pretty hard to hack." The gun can have up to 999 authorized users, and its accuracy at detecting fingerprints is 99.99%. For winning the challenge, he won $50,000 in funding to continue developing the smart gun. Some of the fund have already gone toward 3-D printing portions of the prototype.

If We Can't Kill Cancer, Can We Control It?

slashdot.org - dg, 14/09/2014 - 10:20
An anonymous reader sends this excerpt from The New Yorker: In April, [Dr. Eytan Stein] presented his findings to a packed auditorium at the annual meeting of the American Association for Cancer Research, in San Diego. It was the first public airing of the results of AG-221; patients with progressive [acute myelogenous leukemia] had never improved so quickly and definitively. ... The breakthrough is notable in part for the unconventional manner in which the drug attacks its target. There are many kinds of cancer, but treatments have typically combated them in one way only: by attempting to destroy the cancerous cells. Surgery aims to remove the entire growth from the body; chemotherapy drugs are toxic to the cancer cells; radiation generates toxic molecules that break up the cancer cells' DNA and proteins, causing their demise. A more recent approach, immunotherapy, co-opts the body's immune system into attacking and eradicating the tumor. The Agios drug, instead of killing the leukemic cells — immature blood cells gone haywire — coaxes them into maturing into functioning blood cells. Cancerous cells traditionally have been viewed as a lost cause, fit only for destruction. The emerging research on A.M.L. suggests that at least some cancer cells might be redeemable: they still carry their original programming and can be pressed back onto a pathway to health.

NSA Metadata Collection Gets 90-Day Extension

slashdot.org - dg, 14/09/2014 - 07:43
schwit1 sends word that the Foreign Intelligence Surveillance Court has authorized a 90-day extension to the NSA's ability to collect bulk metadata about U.S. citizens' phone calls. In April, the House of Representatives passed a bill to limit the NSA's collection of metadata, but the Senate has been working on their version of the bill since then without yet voting on it. Because of this, and the alleged importance of continuing intelligence operations, the government sought a 90-day reauthorization of the current program. The court agreed. Senator Patrick Leahy said this clearly demonstrates the need to get this legislation passed. "We cannot wait any longer, and we cannot defer action on this important issue until the next Congress. This announcement underscores, once again, that it is time for Congress to enact meaningful reforms to protect individual privacy.

Technological Solution For Texting While Driving Struggles For Traction

slashdot.org - dg, 14/09/2014 - 04:04
An anonymous reader writes: While legislators and police try to tackle the epidemic of distracted driving through education, regulation, and enforcement, Scott Tibbitts is trying to solve it through engineering. He developed a small device which, when plugged into a vehicle, would determine which phone belonged to the driver and shut off its texting and voice call capabilities. "The telematics box sends a wireless message that the car is moving. The phone sends its own message about its location. Both sets of information — from the car and phone — are sent to Katasi's servers. Then, an algorithm weighs the incoming data with other information, like the location of the phones belonging to all the people who drive the car and the starting point of the trip; if the trip starts at Junior's high school, and mom and dad's phones are at work, the driver has been identified — Junior is driving." The problem is that Tibbitts can't get anyone interested in setting up a system to make these devices ubiquitous. Consumers can't be sold on such a product: all evidence suggests people are increasingly unwilling to be cut off from constant communication. So, he tried working with carriers. Sprint partnered with Tibbitts long enough to test the device, but they were afraid of the legal risks involved. Now, Tibbitts is nursing the technology along, looking for a way to get it into cars and make people safer.

US Patent Office Seeking Consultant That Can Stamp-out Fraud By Patent Examiners

slashdot.org - dg, 14/09/2014 - 01:00
McGruber writes: A month after Slashdot discussed "Every Day Is Goof-Off-At-Work Day At the US Patent and Trademark Office," the USPTO issued a statement that it is "committed to taking any measures necessary" to stop employees who review patents from lying about their hours and getting overtime pay and bonuses for work they didn't do. USPTO officials also told congressional investigators that they are seeking an outside consulting firm to advise them on how managers can improve their monitoring of more than 8,000 patent examiners. The Patent Examiners union responded to the original Washington Post report with a statement that includes this line: "If 'thousands' of USPTO employees were not doing their work, it would be impossible for this agency to be producing the best performance in recent memory and, perhaps, in its entire 224 year history." In related news, USPTO Commissioner Deborah Cohn has announced plans to resign just months after a watchdog agency revealed that she had pressured staffers to hire the live-in boyfriend of an immediate family member over other, better-qualified applicants. When he finished 75th out of 76 applicants in the final round of screening, Cohn "intervened and created an additional position specifically for the applicant," wrote Inspector General Todd Zinser in a statement on the matter.

Why Atheists Need Captain Kirk

slashdot.org - ds, 13/09/2014 - 23:50
New submitter anlashok writes: Atheism and science face a real challenge: To frame an account of science, or nature, that leaves room for meaning. According to this article, atheists have pinned their flag to Mr. Spock's mast. But they need Captain Kirk. Quoting: "I'm pro-science, but I'm against what I'll call "Spock-ism," after the character from the TV show Star Trek. I reject the idea that science is logical, purely rational, that it is detached and value-free, and that it is, for all these reasons, morally superior. Spock-ism gives us a false picture of science. It gives us a false picture of humankind's situation. We are not disinterested knowers. The natural world is not a puzzle. ... The big challenge for atheism is not God; it is that of providing an alternative to Spock-ism. We need an account of our place in the world that leaves room for value."

US Scientists Predict Long Battle Against Ebola

slashdot.org - ds, 13/09/2014 - 22:38
An anonymous reader writes: Despite recent advances in medicine to treat Ebola, epidemiologists are not hopeful that the outbreak in west Africa will be contained any time soon. Revised models for the disease's spread expect the outbreak to last 12 to 18 months longer, likely infecting hundreds of thousands of people. "While previous outbreaks have been largely confined to rural areas, the current epidemic, the largest ever, has reached densely populated, impoverished cities — including Monrovia, the capital of Liberia — gravely complicating efforts to control the spread of the disease. ... What worries public health officials most is that the epidemic has begun to grow exponentially in Liberia. In the most recent week reported, Liberia had nearly 400 new cases, almost double the number reported the week before. Another grave concern, the W.H.O. said, is 'evidence of substantial underreporting of cases and deaths.' The organization reported on Friday that the number of Ebola cases as of Sept. 7 was 4,366, including 2,218 deaths." Scientists are urging greater public health efforts to slow the exponential trajectory of the disease and bring it back under control.

The Future According To Stanislaw Lem

slashdot.org - ds, 13/09/2014 - 21:30
An anonymous reader writes "The Paris Review has an article about SF author Stanislaw Lem, explaining Lem's outlook on the future and his expectations for technological advancement. Lem tended toward a view that technology would infect and eventually supplant biological evolution. But he also suggested an interesting explanation for why we haven't detected alien civilizations: "Perhaps ... they are so taken up with perfecting their own organisms that they've abandoned space exploration entirely. According to a similar hypothesis, such beings are invisible because technological ease has resulted in a 'Second Stone Age' of 'universal illiteracy and idleness.' When everyone's needs are perfectly met, it 'would be hard, indeed, to find one individual who would choose as his life's work the signaling, on a cosmic scale, of how he was getting along.' Rather than constructing Dyson Spheres, Lem suggests, advanced civilizations are more likely to spend their time getting high.""

Justice Sotomayor Warns Against Tech-Enabled "Orwellian" World

slashdot.org - ds, 13/09/2014 - 20:16
An anonymous reader writes: U.S. Supreme Court Justice Sonia Sotomayor spoke on Thursday to faculty and students at the University of Oklahoma City about the privacy perils brought on by modern technology. She warned that the march of technological progress comes with a need to enact privacy protections if we want to avoid living in an "Orwellian world" of constant surveillance. She said, "There are drones flying over the air randomly that are recording everything that's happening on what we consider our private property. That type of technology has to stimulate us to think about what is it that we cherish in privacy and how far we want to protect it and from whom. Because people think that it should be protected just against government intrusion, but I don't like the fact that someone I don't know can pick up, if they're a private citizen, one of these drones and fly it over my property."

DARPA Funds Harvard's Soft Exoskeletal Suit

slashdot.org - ds, 13/09/2014 - 19:04
An anonymous reader writes: The military and private contractors have been toying with exoskeletal combat suits for a while, but Harvard's Wyss Institute has a new take on the concept. Rather than using a hard metal frame and the massively overpowered mechanical servos necessary to move it, the Soft Exosuit is a lightweight mesh of webbing combined with a series of strain sensors and basic microprocessors. "The suit mimics the action of leg muscles and tendons when a person walks, and provides small but carefully timed assistance at the leg joints without restricting the wearer's movement." The suit continually monitors its wearer's body position, movement, and muscular strain, providing small amounts of targeted support. The team has now received $2.9 million in funding from DARPA to refine the suit's design. They say they'll be working on medical applications for the suit as well as military ones.

The Challenges and Threats of Automated Lip Reading

slashdot.org - ds, 13/09/2014 - 16:45
An anonymous reader writes: Speech recognition has gotten pretty good over the past several years. it's reliable enough to be ubiquitous in our mobile devices. But now we have an interesting, related dilemma: should we develop algorithms that can lip read? It's a more challenging problem, to be sure. Sounds can be translated directly into words, but deriving meaning out of the movement of a person's face is much more complex. "During speech, the mouth forms between 10 and 14 different shapes, known as visemes. By contrast, speech contains around 50 individual sounds known as phonemes. So a single viseme can represent several different phonemes. And therein lies the problem. A sequence of visemes cannot usually be associated with a unique word or sequence of words. Instead, a sequence of visemes can have several different solutions." Beyond the computational aspect, we also need to decide, as a society, if this is a technology that should exist. The privacy implications extend beyond that of simple voice recognition.

The MOOC Revolution That Wasn't

slashdot.org - ds, 13/09/2014 - 15:41
An anonymous reader writes: Dan Friedman at TechCrunch is ready to call Massive Open Online Courses a failure. Originally hailed as a revolution in learning, MOOCs have seen disappointing course completion numbers. Coursera and Udacity, two of the most prominent online learning hubs, have seen about 8 million enrollments in the past few years. Unfortunately, half of those students didn't even watch a single lecture, and only a few hundred thousand completed the course they signed up for. Friedman says, "[N]ew technologies enable methods of "learn by doing" that just weren't possible before we could deliver immersive experiences to people's laptops and phones. In the 1960's, Jerome Bruner expanded an educational theory known as constructivism with the idea that students should learn through inquiry under the guidance of a teacher to grasp complex ideas intuitively. That process of trial, failure, and then being shown the correct path has been proven to drive student motivation and retention of learning. What we don't yet know is if that process of trial and failure can become 10x more engaging when delivered through a new medium such as Minecraft or Oculus. ... These new immersive worlds promise to hold the attention of students in ways textbooks never could."
