Newly Discovered Greenhouse Gas Is 7,000 Times More Powerful Than CO2 216

Hugh Pickens DOT Com writes "Suzanne Goldenberg writes at The Guardian that researchers at the University of Toronto's department of chemistry have identified a newly discovered greenhouse gas, perfluorotributylamine (PFTBA), in use by the electrical industry since the mid-20th century, that is 7,000 times more powerful than carbon dioxide at warming the Earth. 'We claim that PFTBA has the highest radiative efficiency of any molecule detected in the atmosphere to date,' says Angela Hong. Concentrations of PFTBA in the atmosphere are low – 0.18 parts per trillion in the Toronto area – compared to 400 parts per million for carbon dioxide but PFTBA is long-lived. There are no known processes that would destroy or remove PFTBA in the lower atmosphere so it has a very long lifetime, possibly hundreds of years, and is destroyed in the upper atmosphere. 'It is so much less than carbon dioxide, but the important thing is on a per molecule basis, it is very very effective in interacting with heat from the Earth.' PFTBA has been in use since the mid-20th century for various applications in electrical equipment, such as transistors and capacitors. 'PFTBA is just one example of an industrial chemical that is produced but there are no policies that control its production, use or emission,' says Hong. 'It is not being regulated by any type of climate policy.'"

+ - The math behind beaming a human->

Submitted by pjbass
pjbass (144318) writes "A group of physics students from the University of Leicester recently undertook the question, "how long would it take to beam a human being?" While some loose assumptions were made regarding available bandwidth (and its impact on the time to transfer the data), it is very interesting to see how much "data" a human being occupies."

Yet another prime example of why alien civilizations won't contact us openly: How can a truly civilized race possibly take us as anything other than animals when we still do things like this? Our so-called "civilization" is just as thin a patina over the animal underneath as our neo-cortex is over the rest of our brains. It's positively heartbreaking to read of things like this in this day and age when I know that the human race, at it's best, is in such stark contrast with such senseless ignorance and brutality.

I don't disagree with your overall premise, but what says that an alien civilization with technology to travel inter-planet has to be a truly civilized race?

+ - Short interview with kernel.org's Warthog9->

Submitted by Anonymous Coward
An anonymous reader writes "After the events of last year, kernel.org needed to redo their infrastructure. Intel was proud to help out and provide all new Intel® Ethernet X520 adapters to the kernel.org team. Team member John 'Warthog9' Hawley was kind enough to spend a few minutes answering some questions for us and I figured I’d share his answers.He shares some little known details about the kernel.org infrastructure that we all know and love. And since IT can often be thankless, thanks to John and the rest of the behind the scenes people that keep Linux moving forwards. (Full disclosure, I edited the article)"

Sorry, but this isn't significant. And to be honest, it sounds like it should be in the noise. Flash memory is flash memory. The cell can swell based on many environmental factors (air pressure changes, humidity, temperature, etc.), and TFA clearly mentions heat as a possible factor. The fact a downloaded piece of data measured at all could be the cells were heated as the gates were being used to store the data. Who knows. A billionth of a billionth of a gram for 4GB of data just sounds too tiny to be remotely significant, let alone noteworthy outside of an extremely controlled environment.

I'd like to see more data on the experiment itself, to see if the measurements were all taken in a very controlled environment or not. TFA is really lacking any details that would intrigue people who cared.

The issue today though isn't in-house vs. colocated, it's cost. Most of these companies don't have the cash to build proper infrastructure to house their services locally. The cloud services from various companies, like Amazon, take care of the physical maintenance and cooling and power, etc.

Even if your local datacenter housed mission-critical data, I'm sure it's possible to come up with 100 scenarios where you could lose all connectivity to your locally-housed infrastructure (power company accidentally digs up your comm lines, etc.).

The cloud isn't perfect, but neither is in-house colocation. It depends on how much money you want to spend for the control. Even with the control, you can't plan for the worst and still remain cost-effective. This is just a crappy situation that is amplified given how many people rely on the services.

I don't play games on my laptop, but I do run compiz-fusion with many of the features enabled. It's very eye-candy-heavy, and my integrated Intel graphics chip keeps up just fine. My CPUs don't bear much load at all. I don't think things are as grossly out of proportion as you make them out to be. 5 years ago, yes. Today, not so much.

Users' Admin Logins Make Most Windows Malware Worse 420

nandemoari writes "A new analysis claims that over 90% of the Windows security vulnerabilities reported last year were made worse by users logged in with administrative privileges — an issue Microsoft has been hotly debating recently. According to BeyondTrust Corp., the result of the analysis of the 154 critical Microsoft vulnerabilities indicated that a full 92% could have been prevented if users were not logged into their systems with administrator status. BTC believes that restricting the number of users who can log in with these privileges will 'close the window of opportunity' for attackers. This is particularly true for users of Internet Explorer and Microsoft Office."

Another big portion is companies like Novell contract themselves to other companies to do their kernel development for them. AMD, for example, pays Novell to do their kernel work for them. This isn't an uncommon practice, since RedHat also gets money from other companies to do their development work in the kernel. But when it comes down to it, the actual "originator" of the code or concept may not be Novell or RedHat, but they're the email address getting merged on the Signed-off-by: lines, which isn't a big deal.

I don't see this as anything evil or underhanded, being a network stack hacker myself. The kernel maintainers and core contributers are far from stupid and gullible, and will *not* accept anything if they see proprietary undertones. I'm also sure they're putting a bit more scrutiny into reviewing patches from Novell just because. But the bottom line is more people are working on the kernel, trying to make it better, which is the end-goal. It really, in my mind, doesn't matter who is doing it, just as long as it's getting done and done well.

prostoalex writes "USA Today interviews Jim Buckmaster, CEO of popular online classifieds site CraigsList. The company currently has 23 employees, never paid a single dime to advertise itself, but nevertheless is 9th most popular Web site in the US (USA Today quotes Alexa). Viewed as a major factor in declining newspaper subscriptions, CraigsList has this to say: "On the charge of "stealing" ads from newspapers, Buckmaster remains quietly unapologetic. The big newspaper chains continue to be about twice as profitable as the average American business, he says, "so it's not as though they're hurting." Newspapers have become "beholden to Wall Street," he says. "The primary focus is not necessarily on journalism; it's on maximizing revenue.""
