First Measurement of Magnetic Field In Earth's Core 34

An anonymous reader writes "A University of California, Berkeley, geophysicist has made the first-ever measurement of the strength of the magnetic field inside Earth's core, 1,800 miles underground. The magnetic field strength is 25 Gauss, or 50 times stronger than the magnetic field at the surface that makes compass needles align north-south. Though this number is in the middle of the range geophysicists predict, it puts constraints on the identity of the heat sources in the core that keep the internal dynamo running to maintain this magnetic field."

Man Takes Up Internal Farming 136

RockDoctor writes "'A Massachusetts man who was rushed to hospital with a collapsed lung came home with an unusual diagnosis: a pea plant was growing in his lung.' Just that summary should tell you enough to work out most of the rest of the details, but it does raise a number of questions unaddressed by the article: How did the pea roots deal with the patient's immune system? What would have happened if the situation had continued un-treated? I bet the guy has a career awaiting him in PR for a pea-growing company."

Well I say self publish AND fuck the radio stations too.

The real reason that the RIAA and the media groups are going after p2p and internet streaming is that they would like to abolish/control a much more flexible and cheaper method of distribution than CDs and radio.

So make your own music. Play it in the park. Share with your friends stream it on the internet and do it for free.

I agree about the importance of privacy regardless of where you register on the something-to-hide-o-meter, and I agree that Google really dropped the ball on Buzz's privacy settings, but at the same time you really need to question the wisdom of using a "private Gmail account" for anything other than Gmail. Google's been ladling the social sauce on to all of their services over the past couple of years, so it's not like that person didn't have the opportunity to see this coming.

Its not about "shutting the fuck up" or even being introspective (which one should be able to do without a computer/mobile device in their hands). Its about being able to handle yourself without some sort of on demand self-determined audio/visual stimulation.

I am genuinely concerned that kids are living in a world where they are almost always able to distance themselves from the here and now. They are not as empathic, not inclined to listen or engage in, or with, the unfamiliar when its not self-directed. Not that kids aren't 'bored enough' but its being able to genuinely think and act creatively in an otherwise blank slate of time that kids are missing out on. /plus I like to think, "what happens when the bombs fall and we don't have technology to coddle us every single second of our lives?" Power outages become truly devastating when kids are emotionally tethered to their devices.

Snapshot what you get - don't change it, don't even look at it. As soon as you get it, check it in, binaries and all, to a change tracking system (eg, CVS, SVN, etc).

This I agree with but for one thing: Verify that the binaries you are given correspond to the code you are given. I've seen it too many times where they release a binary, then go back and do 'minor' bug fixes and don't recompile before handing it off to you.

Save the binaries you've been given, then do a clean recompile and compare the two versions as well!

Wrong. Wrong, And Wrong!

But they were the ones who put the word pirate in the name of their site.

Originally PirateBay published economic trends. They used the price of Four'n'Twenties as a cost of living indicator.

Hence the name - "Pi Rate" which translates into English as "cost of a meat pie".

the city would be called Boozer City.

Which I think does exist somewhere in Australia

There is no city in this fine and fair land called "Boozer City". You fool! (perhaps you've just come back from BongBong - hopefully Mount Camel was not on the way)

All the towns are called "Boozer Town". The cities, going clockwise from the bottom-south, are Shooter City, Underbelly City, City of Colour and Movement, PartyCrash City, Big Stubby City, Bundaberg City, Ice City, and (my city) Tired And Emotional Politician City.

Don't listen to the talking Polar Bear on the bottle - he studied at the school of Tallho Rolling paper trivia.

Wrong again! You are watching the dishwasher (and that is a mouse in your hand).

Make sure your GRUB shows the new 2.6.31 kernel. When I upgraded, the kernel installed, but it didn't run update-grub, and so my GRUB menu didn't show the new kernel. When it booted into the old kernel, I had the same problem as you, where it showed that no audio devices were installed. Merely booting into the proper new kernel fixed it.

You've got to factor in the bias of the poll - the people likely to be looking around on the forums and especially at items related to the upgrade are likely to be those who have issues. A user who has updated without any hitches is likely to get on with whatever they want to do with the computer, not go to the forums and respond to a poll.

RobDude - I hear your frustration. Personally, it's been quite some time since I had a *serious* hardware problem. Yeah, I struggled, until about the time Suse 9 came out. With that download, everything "just worked" for me. Things have gotten better since then, as well. But, that doesn't help the guy with this thing, or that gadget for which there IS NO SUPPORT! So, I hear you.

Did you contact the vendor of the gadget that refused to work? Yeah - it's a pain, just one more pain in a long list of pains when the gadget doesn't work. But, I hope you DID contact the mfgr, and give them a good cussing out.

Doing so makes them aware that more and more of the world is using Linux, and that they can make money by supplying a driver for us. I've contacted several, myself. It ain't that big a deal, but if it helps to convince one mfr to support Linux, well, I've done a little bit for the community.

BTW - you are aware that not every distro and/or repository supports the same hardware? If you feel like experimenting, you might try some Live-CD's to see which if any makes your gadget work. Just an idea......

Alas, as others have pointed out upthread, the high-temp superconductors don't work well for magnets. All superconducting materials lose their superconductivity at a certain magnetic field-strength threshold; for high-Tc materials, that threshold is much lower than it is for "conventional" superconductors.

Even if that weren't an issue, the ceramic materials are generally too brittle to stand up to the mechanical forces inside a high-field magnet coil.

Our lab has experimented with high-Tc superconducting probes for MRI. Even though they're high-Tc, we still end up cooling them to the liquid-helium range.
