Mars (One) Needs Payloads 24

Posted by timothy
from the ok-but-nothing-too-heavy dept.
mbone (558574) writes Mars One has announced that their first, unmanned, lander, targeted for 2018, needs payloads. Along with their 4 experiments, and a University experiment, they have two payloads for hire: "Mars One offers two payload opportunities for paying mission contributors. Proposals can take the form of scientific experiments, technology demonstrations, marketing and publicity campaigns, or any other suggested payload. 'Previously, the only payloads that have landed on Mars are those which NASA has selected,' said Bas Lansdorp, 'We want to open up the opportunity to the entire world to participate in our mission to Mars by sending a certain payload to the surface of Mars.'" The formal Request for Proposals for all of this is out now as well.

+ - Magnetic Field of Earth Weakening a Sign Poles Are Flipping->

Submitted by Trachman
Trachman (3499895) writes "The magnetic field of Earth is weakening more rapidly than many scientists thought it would, a sign that Earth’s magnetic poles might flip within a few hundred years as opposed to thousands of years. Data collected from Swarm, the collective name for three European Space Agency (ESA) satellites, confirms that Earth’s magnetic field is weakening, something which has led to many past switches in Earth’s magnetic poles.Deep ocean core studies have confirmed, according to NASA, that the Earth’s magnetic poles reverse on a relatively frequent basis. They usually switch anywhere from 200,000 to 300,000 years. As it has been 700,000 years or so since a flip has taken place, Earth is overdue for one. The weakening magnetic field might be a sign that the switch will occur sooner, rather than later. Scientists, according to a report by LiveScience, had thought that Earth’s magnetic field was weakening by about five percent every hundred years. At that rate, they calculated that a flip in the Earth’s magnetic fields would not happen for around another 2,000 years. However, the new data from Swarm indicates that Earth’s magnetic field is actually currently weakening at a rate of five percent every decade instead of century. That rate is 10 times faster than the scientists had allowed for in their calculations about when the next flip would happen. That being said, we know that the Earth's magnetic field is primary protecting shield from cosmic particles and, consequently, is a primary factor to the Earth's temperature.

My Scoop is following: At the risk of being not popular here at Slashdot I dare to ask: can magnetic field changes and climate changes be connected and analyzed in concert?"

O3b Launches Four More Satellites To Bring Internet To 'Other 3 Billion' 40

Posted by timothy
from the from-above dept.
An anonymous reader writes "O3b Networks is aiming to provide internet access through satellite, to the "other three billion" people in under-served equatorial regions (Africa, the Pacific, South America). O3b launched four more satellites [Thursday], to add to the four they already have in orbit. This is a very international effort; a Russian Soyuz rocket went up from South America, carrying satellites built in France. There's a video of the rocket and payloads coming together and a video of the rocket launch. There's also an academic paper describing using the O3b system from the Cook Islands in the Pacific, giving an idea of what it does and those all-important ping times."

Lyft's New York Launch Halted By Restraining Order 48

Posted by timothy
from the restraining-competition-is-more-like-it dept.
Forbes reports that Lyft's planned expansion into the New York market has been delayed by a restraining order. The article explains that State officials had asked Lyft to delay its launch. When Lyft refused, New York Attorney General Eric Schneiderman's office filed a temporary restraining order against the startup Friday morning to prevent its launch. Other statements said that the restraining order had been granted, though Simpson said that was untrue. Lyft and officials will reconvene in court Monday for a hearing. Lyft will not launch until it has reached an agreement with the city, Simpson said. Since Monday, when Lyft announced it was planning to launch in the two boroughs [of Queens and Brooklyn], the app has faced criticism from city officials. The taxi and limousine commission declared the app 'unauthorized' and said its riders were at risk and its drivers could be cited and fined if they were caught using it. Lyft seems to to have left riders mostly unscathed in Boston, where it's been operating since early last year, and in numerous other cities. Also at Ars Technica.

"Internet's Own Boy" Briefly Knocked Off YouTube With Bogus DMCA Claim 81

Posted by timothy
from the until-proven-innocent dept.
An anonymous reader writes "In a bitter irony, a documentary celebrating Aaron Swartz, the late Internet activist who helped create the Creative Commons, has been taken down from YouTube by a misguided copyright claim." From the article: [O]ne of the dark sides of how copyright is enforced on the Internet is that sites that don't actually infringe are sometimes mistakenly swept up in rightsholders' takedown notices, which are frequently automated. Visitors who tried to watch The Internet's Own Boy on YouTube Friday were greeted by the message, "This video is no longer available due to a copyright claim by Remove Your Media LLC," a reference to a company that specializes in sending copyright takedowns in accordance with the law that governs them, the Digital Millenium Copyright Act (DMCA). It's not clear who made the claim, but that's not the point—as activists are all too aware, false copyright claims can can knock legitimate content offline.

DARPA Successfully Demonstrates Self-Guiding Bullets 128

Posted by Soulskill
from the jerks-with-aim-bots dept.
Lucas123 writes: A DARPA-funded project has successfully developed a .50 caliber sniper round capable of maneuvering during flight in order to remain on target. The self-guiding EXACTO bullet, as it's being called, is optically guided by a laser that must remain on target for the bullet to track. The EXACTO round is capable of accurately tracking a target up to 1.2 miles away, DARPA stated. The technology, which is being developed by Teledyne Scientific and Imaging, is targeted at helping snipers remain at longer distances from targets as well as improving night shots. While DARPA's tracking bullet is the first to use a standard, small-arms caliber round, in 2012 Sandia National Laboratories (SNL) successfully demonstrated a prototype self-guided bullet that was more like like a four-inch dart.

+ - FAA Intimidates Coldwell Banker, Other Realtors Into Shunning Drone Photography-> 1

Submitted by mpicpp
mpicpp (3454017) writes "For months, the Federal Aviation Administration (FAA) has been investigating realtors who use drones to film their properties. Now, Forbes has learned that the FAA’s investigations have succeeded in intimidating NRT —the nation’s largest residential real estate brokerage company — into advising their members to not only cease flying drones as part of their work, but to also cease using drone footage.

This is a troubling development in an ongoing saga over the FAA’s rules which punish the safe commercial use of drones. Currently, the FAA does not prohibit the use of drones for a hobby — flying over your home and taking pictures of it for fun is allowed, but because real estate drones take pictures for a commercial purpose, the FAA prohibits their use."

Ask Slashdot: Unattended Maintenance Windows? 234

Posted by Soulskill
from the wake-me-if-there's-fire dept.
grahamsaa 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?

Child Thought To Be Cured of HIV Relapses, Tests Positive Again 117

from the poor-kid dept.
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.

Google's Experimental Newsroom Avoids Negative Headlines 104

Posted by Soulskill
from the giant-earthquake-provides-thousands-with-early-access-to-afterlife dept.
theodp 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.

While much of his declaration consists of vague and positive-sounding phrases ("crease the fluidity of information and ideas by taking actions to flatten the organization and develop leaner business processes"), he outlined his main goals for the shift: reduce time it takes to get things done by having fewer people involved in each decision; quantify outcomes for products and use that data to predict future trends; and increasing investment for employee training and development."
