Finding Life In Space By Looking For Extraterrestrial Pollution

Slashdot - 33 min 5 sec ago
coondoggie writes: If what we know as advanced life exists anywhere other than Earth, then perhaps they are dirtying their atmosphere as much as we are. We could use such pollution components to perhaps more easily spot such planets. That's the basis of new research published this week by researchers at the Harvard-Smithsonian Center for Astrophysics. They say that if we could spot the fingerprints of certain pollutants under ideal conditions (PDF), it would offer a new approach in the search for extraterrestrial intelligence."

The Secret Government Rulebook For Labeling You a Terrorist

Slashdot - 1 hour 15 min ago
Advocatus Diaboli sends this report: The Obama administration has quietly approved a substantial expansion of the terrorist watchlist system, authorizing a secret process that requires neither "concrete facts" nor "irrefutable evidence" to designate an American or foreigner as a terrorist, according to a key government document obtained by The Intercept. ...The heart of the document revolves around the rules for placing individuals on a watchlist. "All executive departments and agencies," the document says, are responsible for collecting and sharing information on terrorist suspects with the National Counterterrorism Center. It sets a low standard—"reasonable suspicion"—for placing names on the watchlists, and offers a multitude of vague, confusing, or contradictory instructions for gauging it. In the chapter on "Minimum Substantive Derogatory Criteria"—even the title is hard to digest—the key sentence on reasonable suspicion offers little clarity.

'Just Let Me Code!'

Slashdot - 1 hour 56 min ago
An anonymous reader writes: Andrew Binstock has an article about the ever-increasing complexity required to write code. He says, "I got into programming because I like creating stuff. Not just any stuff, but stuff other people find useful. I like the constant problem solving, the use of abstractions that exist for long periods nowhere but in my imagination, and I like seeing the transformation into a living presence. ... The simple programs of a few hundred lines of C++ long ago disappeared from my experience. What was the experience of riding a bicycle has become the equivalent of traveling by jumbo jet; replete with the delays, inspections, limitations on personal choices, and sudden, unexplained cancellations — all at a significantly higher cost. ... Project overhead, even for simple projects, is so heavy that it's a wonder anyone can find the time to code, much less derive joy from it. Software development has become a mostly operational activity, rather than a creative one. The fundamental problem here is not the complexity of apps, but the complexity of tools. Tools have gone rather haywire during the last decade chasing shibboleths of scalability, comprehensiveness, performance. Everything except simplicity."

Intel Launches Self-Encrypting SSD

Slashdot - 2 hours 38 min ago
MojoKid writes: Intel just launched their new SSD 2500 Pro series solid state drive, the follow-up to last year's SSD 1500 Pro series, which targets corporate and small-business clients. The drive shares much of its DNA with some of Intel's consumer-class drives, but the Pro series cranks things up a few notches with support for advanced security and management features, low power states, and an extended management toolset. In terms of performance, the Intel SSD 2500 Pro isn't class-leading in light of many enthusiast-class drives but it's no slouch either. Intel differentiates the 2500 Pro series by adding support for vPro remote-management and hardware-based self-encryption. The 2500 Pro series supports TCG (Trusted Computing Group) Opal 2.0 features and is Microsoft eDrive capable as well. Intel also offers an administration tool for easy management of the drive. With the Intel administration tool, users can reset the PSID (physical presence security ID), though the contents of the drive will be wiped. Sequential reads are rated at up to 540MB/s, sequential writes at up to 480MB/s, with 45K – 80K random read / write IOps.

'Optical Fiber' Made Out of Thin Air

Slashdot - 3 hours 20 min ago
Dave Knott writes: Scientists from the University of Maryland say they have turned thin air into an "optical fiber" that can transmit and amplify light signals without the need for any cables. As described in the research, this was accomplished by generating a laser with its light split into a ring of multiple beams forming a pipe. Very short and powerful pulses from the laser are used to heat the air molecules along the beam extremely quickly. Such rapid heating produces sound waves that take about a microsecond to converge to the center of the pipe, creating a high-density area surrounded by a low-density area left behind in the wake of the laser beams. The lower density region of air surrounding the center of the air waveguide has a lower refractive index, keeping the light focused, and allowing the higher-density region (with its correspondingly higher index of refraction) to act like an optical fiber. The findings, reported in the journal Optica, have applications in long range laser communications, high-resolution topographic mapping, air pollution and climate change research, and could also be used by the military to make laser weapons.

The Department of Homeland Security Needs Its Own Edward Snowden

Slashdot - 4 hours 3 min ago
blottsie writes: Out of all the U.S. government agencies, the Department of Homeland Security is one of the least transparent. As such, the number of Freedom of Information Act requests it receives have doubled since 2008. But the DHS has only become more adamant about blocking FOIA requests over the years. The problem has become so severe that nothing short of an Edward Snowden-style leak may be needed to increase transparency at the DHS.

Researchers Print Electronic Memory On Paper

Slashdot - 5 hours 25 min ago
MTorrice (2611475) writes Electronics printed on paper promise to be cheap, flexible, and recyclable, and could lead to applications such as smart labels on foods and pharmaceuticals or as wearable medical sensors. Many engineers have managed to print transistors and solar cells on paper, but one key component of a smart device has been missing—memory. Now a group of researchers has developed a method that uses ink-jet technology to print resistive random access memory on an ordinary letter sized piece of paper. The memory is robust: Engineers could bend the device 1,000 times without any loss of performance. The memory is not yet very dense, but could be: "Each silver dot they printed was approximately 50 microns across and separated from its neighbor by 25 microns, so each bit of memory is 100 microns on a side. At that size, a standard 8.5- by 11-inch piece of paper can hold 1 MB of memory. Der-Hsien Lien, the paper's lead author, says existing ultrafine ink-jet technology can produce dots less than 1 micron across, which would allow the same piece of paper to hold 1 gigabyte. Reading and writing the bits takes 100 to 200 microseconds"

SpaceX Releases Video of Falcon Rocket's Splashdown

Slashdot - 5 hours 45 min ago
First time accepted submitter cowdung (702933) writes In spite of Elon Musk's characterization of the landing as a KABOOM event. Judging by this video SpaceX has managed to land the first stage rocket booster nicely on the ocean after their Orbcomm launch on July 14th. It seems we're one step closer to a landing on dry land. Both this and the previous landing seem to have gone well. Hopefully the next landing test camera has something to deice the camera lens.

Microsoft FY2014 Q4 Earnings: Revenues Up, Profits Down Slightly

Slashdot - 6 hours 4 min ago
Microsoft has released their latest earnings report, and it's not as bleak as last week's news might have you suspect. Quoting Forbes: Microsoft reported $23.38 billion of revenue for the fourth quarter, up 17.5% from the same period last year. Net income, however, came in at $4.6 billion, down from last year and behind Wall Street analysts' consensus estimate, both about $5 billion. At 55 cents earnings per share were down 4 cents and a nickel short of the Street’s call. For the full year, revenue clocked in at $86.8 billion an 11.5% increase from a year earlier. Net income was $22.1 billion and earnings per share were $2.63. They took a hit from finalizing the acquisition of Nokia's handset division (not unexpected). The cloud services side of the business appears to be growing, while traditional software sales have stagnated. The layoffs will cost Microsoft between $1.1 and $1.6 billion over the first half of next year.

CNN iPhone App Sends iReporters' Passwords In the Clear

Slashdot - 7 hours 15 min ago
chicksdaddy (814965) writes The Security Ledger reports on newly published research from the firm zScaler that reveals CNN's iPhone application transmits user login session information in clear text. The security flaw could leave users of the application vulnerable to having their login credential snooped by malicious actors on the same network or connected to the same insecure wifi hotspot. That's particularly bad news if you're one of CNN's iReporters — citizen journalists — who use the app to upload photos, video and other text as they report on breaking news events. According to a zScaler analysis, CNN's app for iPhone exposes user credentials in the clear both during initial setup of the account and in subsequent mobile sessions. The iPad version of the CNN app is not affected, nor is the CNN mobile application for Android. A spokesman for CNN said the company had a fix ready and was working with Apple to have it approved and released to the iTunes AppStore.

Robot With Broken Leg Learns To Walk Again In Under 2 Minutes

Slashdot - 7 hours 56 min ago
KentuckyFC (1144503) writes When animals lose a limb, they learn to hobble remarkably quickly. And yet when robots damage a leg, they become completely incapacitated. That now looks set to the change thanks to a group of robotics engineers who have worked out how to dramatically accelerate the process of learning to walk again when a limb has become damaged. They've tested it on a hexapod robot which finds an efficient new gait in under two minutes (with video), and often faster, when a leg becomes damaged. The problem for robots is that the parameter space of potential gaits is vast. For a robot with six legs and 18 motors, the task of finding an efficient new gait boils down to a search through 36-dimensional space. That's why it usually takes so long. The new approach gets around this by doing much of this calculation in advance, before the robot gets injured. The solutions are then ordered according to the amount of time each leg remains in contact with the ground. That reduces the dimension of the problem from 36 to 6 and so makes it much easier for the robot to search. When a leg becomes damaged, the robot selects new gaits from those that minimize contact with the ground for the damaged limb. It compares several and then chooses the fastest. Voila! The resulting gaits are often innovative, for example, with the robot moving by springing forward. The new approach even found a solution should all the legs become damaged. In that case, the robot flips onto its back and inches forward on its "shoulders."
