Could 'Re-Engineering' Earth Help Ease the Hurricane Threat? (nbcnews.com) 262

Posted by msmash from the mission-saving-the-planet dept.
As hurricanes continue to increase in frequency and intensity, a $10-billion-a-year project proposes injecting sulfate into the atmosphere to cool down the Earth and reduce the number of hurricanes by 50% for a staggering 50 years. From a report: In an attempt to combat climate change, a multinational team of scientists are working on a plan to literally re-engineer the Earth in order to cool it down and reduce the impact of storm systems. For example, a team led by John Moore, who is the head of China's geoengineering research program, is studying how shading sulfate aerosols that are dispersed into the stratosphere could help cool the planet and reduce the number of hurricane occurrences. In an interview with Popular Mechanics, outlining how the plan works, Moore asserts, "We're basically mimicking a volcano and saying we're going to put 5 billion tons of sulfates a year into the atmosphere 20 kilometers high, and we'll do that for 50 years." In their current research model, in which the scientists tested a senario where the sulfate injection is doubled over time, the team found that incidences of Katrina-level hurricanes could be maintained (they would be kept at the same rate that we currently see) and that storm surges, which is the rise in seawater level that is caused solely by a storm, could be mitigated by half. The researchers noted that the volcanic eruption in 1912 of Katmai in Alaska "loaded the Northern Hemisphere with aerosol [sulfates], and [was] followed by the least active hurricane season on record." Moore explains that warmer waters can spark and fuel hurricanes, and cooling them with shading sulfates reduces the size and intensity of these hurricanes.

Submission + - Scala: Next Steps (infoworld.com)

rfernand79 writes: Infoworld has an interview with Martin Odersky, designer of Scala, in which they discuss the future of this popular language. Three versions are discussed as being part of the Scala roadmap: The first one (2.12) focuses on better integration with Java 8, and making use of the latest improvements in the JVM. The second one (Aida) focuses on cleaning up the Scala libraries. But the third one (Don Giovani) is about a fundamental rethink of Scala, with a strong focus on simplicity.

Google's Driverless Car and the Logic of Safety 510

Posted by timothy from the professor-I-have-the-solution dept.
mikejuk writes "Google's driverless car could save more than 1 million deaths per year and tens of millions of injuries. It is an impressive achievement, but will we allow it to take over the wheel? Sebastian Thrun puts the case for it in a persuasive TED Talk video. However it may be OK for human drivers to kill millions of people each year but one human fatality might be enough to finish the driverless car project — in fact it might not even take a death as an injury might cause the same backlash. Robot drivers might kill far fewer people than a human driver but it remains to be seen if we can be logical enough to accept the occasional failure of algorithm or hardware. Put simply we might have all seen too many 'evil robot' movies."

Utah To Teach USA is a Republic, Not a Democracy 1277

Posted by CmdrTaco from the only-two-of-three-wives-agree dept.
0ryan0 writes "Utah lawmakers passed a bill today to force public school teachers to teach that the USA is a republic, not a democracy, because a 'Democracy' would have 'Democrat' in it." The good news must be that all issues of unemployment, finance and social service must be resolved in Utah for their legislature to spend time on this. It must be a utopia!

Vatican Bans IOS Confession App 323

Posted by samzenpus from the get-your-iabsolution-somewhere-else dept.
An anonymous reader writes "Despite all the hype that a lowly priest had approved the new confessional app hitting the app store, the truth has now revealed itself. According to today's Daily Mail, a spokesman for the Vatican, Federico Lombardi said: 'It is essential to understand that the rites of penance require a personal dialogue between penitents and their confessor. It cannot be replaced by a computer application. I must stress to avoid all ambiguity, under no circumstance is it possible to confess by iPhone."

Are You Sure SHA-1+Salt Is Enough For Passwords? 409

Posted by CmdrTaco from the good-enough-for-govt-work dept.
Melchett writes "It's all too common that Web (and other) applications use MD5, SHA1, or SHA-256 to hash user passwords, and more enlightened developers even salt the password. And over the years I've seen heated discussions on just how salt values should be generated and on how long they should be. Unfortunately in most cases people overlook the fact that MD and SHA hash families are designed for computational speed, and the quality of your salt values doesn't really matter when an attacker has gained full control, as happened with rootkit.com. When an attacker has root access, they will get your passwords, salt, and the code that you use to verify the passwords."

CouchOne, Membase Merge, Form NoSQL Powerhouse 46

Posted by Roblimo from the one-big-base-instead-of-two-small-ones dept.
Julie188 writes "CouchOne and Membase, two of the most popular noSQL projects, have merged in an attempt to become an open source database powerhouse. Even the company's new name is merged: Couchbase. The founders of the new Couchbase say they will offer the ability to scale from the largest data center and distributed cloud environments all the way down to smartphones and other mobile devices. As is the standard disclaimer during merger announcements, the leaders also promise to continue their support for their open source, community versions of their programs."

Sputnik Moment Or No, Science Fairs Are Lagging 414

Posted by Soulskill from the joe-vs-the-papier-mache-volcano dept.
An anonymous reader writes "The NY Times is running a story about the response from some high school science teachers to Obama's State of the Union address. It's nice that he wants to celebrate science fair winners, they say, but his obsession with standardized math and reading test scores means they have no time to teach students the fundamentals of how to do science. 'I have so many state standards I have to teach concept-wise, it takes time away from what I find most valuable, which is to have them inquire about the world,' said one teacher."
