Nation's Biggest Nuclear Firm Makes a Play For Carbon Credit Cash 8

Posted by samzenpus
from the cash-grap dept.
tomhath writes with this story that make shake up the nuclear industry. "The biggest player in the beleaguered nuclear power industry wants a place alongside solar, wind and hydroelectric power collecting extra money for producing carbon-free electricity. Exelon Corp., operator of the largest fleet of U.S. nuclear plants, says it could have to close three of them if Illinois rejects the company's pitch to let it recoup more from consumers since the plants do not produce greenhouse gases. Exelon and other around-the-clock plants sometimes take losses when wind turbines produce too much electricity for the system. Under the system, electric suppliers would have to buy credits from carbon-free energy producers. Exelon says the plan would benefit nuclear plants, hydroelectric dams, and other solar and wind projects."

NSA: We Mulled Ending Phone Program Before Edward Snowden Leaks 40

Mark Wilson writes Edward Snowden is heralded as both a hero and villain. A privacy vigilante and a traitor. It just depends who you ask. The revelations he made about the NSA's surveillance programs have completely changed the face of online security, and changed the way everyone looks at the internet and privacy. But just before the whistle was blown, it seems that the NSA was considering bringing its telephone data collection program to an end. Intelligence officials were, behind the scenes, questioning whether the benefits of gathering counter-terrorism information justified the colossal costs involved. Then Snowden went public and essentially forced the agency's hand.

from the play-time dept.
Billly Gates writes "Since Unity has been given a liberal license and free for non commercial developers it has become popular. A computer science student Erik Roystan Ross used the tool to remake SuperMario 64 with a modern Unity 5 engine. There is a video here and if you want to play the link is here. You will need Firefox or Chrome which has HTML 5 for gamepad support if you do not want to use the keyboard. "I currently do not have any plans to develop this any further or to resolve any bugs, unless they're horrendously game-breaking and horrendously simple to fix," says Ross.

Experts: Aim of 2 Degrees Climate Goal Insufficient 130

Posted by samzenpus
from the keeping-it-cool dept.
An anonymous reader points out that a long held goal of keeping the Earth's average temperature from rising above 2 degrees Celsius might not be good enough. "A long-held benchmark for limiting global warming is 'utterly inadequate,' a leading U.N. climate scientist declared. Keeping the Earth's average temperature from rising past 2 degrees Celsius – a cap established by studies in the early 1970s – is far too loose a goal, Petra Tschakert, a professor at Penn State University and a lead author of an assessment report for the U.N.'s Intergovernmental Panel on Climate Change, or IPCC, said in a commentary published in the journal Climate Change Responses. Already, with an average increase of just 0.8 degrees Celsius, she wrote, 'negative impacts' are 'widespread across the globe.' Tschakert called for lowering the warming target to 1.5 degrees Celsius."

Former HP CEO Carly Fiorina Near Launching Presidential Bid 160

Posted by samzenpus
from the in-the-hunt dept.
Rambo Tribble writes "Former Hewlett-Packard CEO Carly Fiorina announced on Fox News Sunday that she stood a 'higher than 90 percent' chance of running as a presidential candidate in 2016. Fiorina's tenure at HP was marked by controversy over her leadership, and it is unclear what level of name recognition she enjoys. Her only previous political experience appears to be a failed U.S. Senate seat effort in 2010, as the Republican candidate challenging sitting Democrat Barbara Boxer, in California. Fiorina lost by 10%.

SeaWorld and Others Discover That a Hashtag Can Become a Bashtag 60

Posted by samzenpus
from the getting-hit-with-your-own-stick dept.
HughPickens.com writes Alison Griswold writes that in an effort to improve its tanking image, SeaWorld launched a new advertising campaign this week to educate the public about its "leadership in the care of killer whales" and other work to protect whales in captivity and in the wild. As part of that head-on initiative, someone at SeaWorld decided to invite Twitter users to pose their questions to the company directly using the hashtag #AskSeaWorld. That was not a good idea as twitter users bashed Sea World relentlessly.. "As easy as it is to make fun of SeaWorld here, the real question is why any company still thinks hosting an open Twitter forum could be good for public relations," writes Griswold. "So maybe SeaWorld's social and PR folks just really have no idea what they're doing. Even so, you'd think they'd have learned from the corporate failures before them."

Let's review some of the times this has backfired, starting with the infamous McDonald's #McDStories Twitter campaign of January 2012. Rather than prompting customers to share their heart-warming McDonald's anecdotes, the hashtag gave critics a highly visible forum to share their top McDonald's horror stories. MacDonalds pulled the campaign within two hours but they discovered that crowd-sourced campaigns are hard to control. Three years later the #McDStories hashtag is still gathering comments. "Twitter Q&As are a terrible idea.," concludes Griswold. "A well-meaning hashtag gives critics an easy way to assemble and voice their complaints in a public forum. Why companies still try them is a great mystery. Maybe they'll all finally learn from SeaWorld and give this one horrible PR trick up for good."

Festo Reveals New Robotic Ants and Butterflies 12

Posted by samzenpus
from the metal-swarm dept.
mikejuk writes "Every year around this time of year Festo builds some amazing robot or other — last year it was a kangaroo. What could it possibly do to top previous amazing devices? What about some even more amazing robotic insects. BionicANT is designed not only look good but to demonstrate swarm intelligence. The robot not only looks like an ant, but it works like one. The design makes use of piezo bending transducers rather than servos to move. As well as being able to move its six legs, it also has a piezo-activated pair of pincers. The second insect robot is a butterfly — eMotion. For flying machines these are incredibly lightweight at 32 grams. The bodies are laser sintered and the wings use carbon fiber rods. Two miniature servo motors are attached to the body and each wing. The electronics has a microcontroller, an inertial sensor consisting of gyro, accelerometer and compass and two radio modules. Flying time is around 3 or 4 minutes."

Arduino Dispute Reaches Out To Distributors 56

Posted by samzenpus
from the what's-in-a-name dept.
szczys writes Two companies are claiming ownership of the Arduino Trademark. The most recent development in this sad state of affairs is a letter from Arduino SRL to long-time Distributors of Arduino products. SRL is claiming they are the real Arduino, but there are some tasty tidbits including a Q/A section with some peculiar answers. From the article: "In short, Arduino LLC has been working on developing the Arduino platform, software, and community while Smart Projects / Arduino SRL was the major official producer of the hardware for most boards. Both are claiming to 'be' Arduino, and going after each other in court. So it’s not strange that Arduino SRL would like to try to keep its hold on the distribution channels."

SpaceX's New Combustion Technologies 81

Posted by samzenpus
from the try-this-one dept.
An anonymous reader shares this story that takes a look at some of the advances SpaceX is working on. "Getting a small group of human beings to Mars and back is no easy task, we learned at the recent GPU Technology Conference in San Jose hosted graphics chip and accelerator maker Nvidia. One of the problems with such a mission is that you need a very large and efficient rocket engine to get the amount of material into orbit for the mission, explained Adam Lichtl, who is director of research at SpaceX and who with a team of a few dozen programmers is try to crack the particularly difficult task of better simulating the combustion inside of a rocket engine. You need a large engine to shorten the trip to Mars, too....Not only do you need a lot of stuff to get to Mars and sustain a colony there, but you also need a way to generate fuel on Mars to come back to Earth. All of these factors affect the design of the rocket engine....As if these were not problems enough, there is another really big issue. The computational fluid dynamics, or CFD, software that is used to simulate the movement of fluids and gases and their ignition inside of all kinds of engines is particularly bad at assisting in rocket engine design. 'Methane is a fairly simple hydrocarbon that is perfectly good as a fuel,' Lichtl said. 'The challenge here is to design an engine that works efficiently with such a compound. But rocket engine CFD is hard. Really hard.'"

Comment: "Harder To Invade But Easier To Lock Up" (Score 1) 365

I'd restate as "harder to invade but easier to lock valid personnel out", which seems a classic problem with any secure location. As such, there has to be existing solutions. Having two crew in the cockpit at all times is a good start but not a complete solution. (You could probably think of at least three ways around this.)
