Comment is 400 a special value in nature. (Score 5, Insightful) 376

We just see it as a round number because we use base 10.

So it is actually nothing special.about 400. It is all numerology crap/superstition.

If we instead of 10 fingers, only had 7 fingers, the number would be ... Oh crap ... 400 in base 7 is actually 1111.

The world will end.

Submission + - Bill Gates To Invest $2 Billion In Renewables (theguardian.com)

An anonymous reader writes: Bill Gates has invested about a billion dollars in renewable energy, and now he's ready to double down. Gates announced he will increase his investment in renewable energy technologies to $2 billion in an attempt to "bend the curve" on limiting climate change. He is focusing on risky investments that favor "breakthrough" technologies because he thinks incremental improvements to existing tech won't be enough to meet energy needs while avoiding a climate catastrophe. "There’s no battery technology that’s even close to allowing us to take all of our energy from renewables and be able to use battery storage in order to deal not only with the 24-hour cycle but also with long periods of time where it’s cloudy and you don’t have sun or you don’t have wind. Power is about reliability. We need to get something that works reliably." At the same time, Gates rejected calls to divest himself and his charitable foundation of investments in fossil fuel companies.

Submission + - The Milky Way has a skeleton, and its first "bone" may be huge

StartsWithABang writes: Spiral galaxies contain high density dust at the centers of their spiral arms, forming the skeleton of galactic structure. While these arm-tracing infrared dark clouds had been seen in many galaxies external to our own, none had ever been discovered in the Milky Way. Until, that is, one of these “skeletal” features was discovered using the Spitzer Space Telescope in 2010. Recently, that “bone” was discovered to be even longer than suspected, and may be the central feature of the Scutum-Centaurus arm, the closest major spiral arm to the Sun.

Submission + - Cyber Attack Grounds Polish LOT Aeroplanes

An anonymous reader writes: Around 1,400 unlucky travelers who were set to depart from Warsaw's Frederic Chopin Airport on Sunday had their flights cancelled or delayed for hours, as the computer system that issues flight plans for Polish airline LOT was hacked. It took some five hours to fix the problem, and in the meantime the passengers were either placed on other (non-LOT) flights or given vouchers to stay the night and depart the next morning.

Submission + - Your Toyota's Software has 10,000 Global Variables (safetyresearch.net)

obscuro writes: In 2013, Toyota settled an unintended acceleration lawsuit out of court for $3 million after software forensics experts explained that their system was run on Spaghetti code. This article is the first I'd heard of it and I thought it might also be /.'s first shot at it... or, at least, a chance to stroll down memory lane.

Submission + - Researchers developed stretchable lithium-ion batteries

jan_jes writes: An Arizona State University research team has used a variation of origami, called kirigami, as a design template for batteries that can be stretched to more than 150 percent of their original size and still maintain full functionality. The kirigami-based prototype battery was sewn into an elastic wristband that was attached to a smart watch. The battery fully powered the watch and its functions – including playing video – as the band was being stretched. Few months back Stanford University researchers have invented a bendable aluminium-ion battery(video)

Submission + - Pothole alert system can be a big boon to car owners (dqindia.com)

An anonymous reader writes: The 'Pothole Alert' research technology could help save motorists billions of pounds in punctures, vehicle damage and road accidents every year. Jaguar Land Rover has developed a new connected car technology that will allow a vehicle to identify the location and severity of potholes, broken drains and manhole covers, and then share this data in real-time via the cloud with other vehicles and with road authorities to help them prioritize repairs.

Submission + - Encryption Would Not Have Protected Secret Federal Data Says DHS

HughPickens.com writes: Sean Gallagher reports at Ars Technica that Dr. Andy Ozment, Assistant Secretary for Cybersecurity in the Department of Homeland Security, told members of the House Oversight and Government Reform Committee that in the case of the recent discovery of an intrusion that gave attackers access to sensitive data on millions of government employees and government contractors, encryption would "not have helped" because the attackers had gained valid user credentials to the systems that they attacked—likely through social engineering. Ozment added that because of the lack of multifactor authentication on these systems, the attackers would have been able to use those credentials at will to access systems from within and potentially even from outside the network. "If the adversary has the credentials of a user on the network, they can access data even if it's encrypted just as the users on the network have to access data," said Ozment. "That did occur in this case. Encryption in this instance would not have protected this data."

The fact that Social Security numbers of millions of current and former federal employees were not encrypted was one of few new details emerged about the data breach and House Oversight member Stephen Lynch (D-Mass.) was the one who pulled the SSN encryption answer from the teeth of the panel where others failed. "This is one of those hearings where I think that I will know less coming out of the hearing than I did when I walked in because of the obfuscation and the dancing around we are all doing here. As a matter of fact, I wish that you were as strenuous and hardworking at keeping information out of the hands of hackers as you are in keeping information out of the hands of Congress and federal employees. It's ironic. You are doing a great job stonewalling us, but hackers, not so much."
