I've never seen that. Do you have a reference? I see some snow-like stuff in the freezer all the time but I've never seen hairy ice. The ice spikes were mentioned in SciAm some time ago.
Since most of them are on teh intertubes these days, you'd expect that the average level of know-how is much lower than back in the days when only scientists and 1337 folks were online. That doesn't preclude the existence of some that are knowledgeable of course. But I sometimes wonder why it is that the majority on/. seem to be old farts (like me, cough cough) these days. Maybe today 1337 is to know HTML and Excel formulas?
The growing mechanism is completely different for ice spikes. They grow because water increases its volume right before it freezes. Water at the surface of the volume freezes first when it's in contact with cold air and then some water is squeezed out of the last remaining opening in the surface ice.
The whole WEEE/RoHS thing originated in Europe but then other states/countries got on the bandwagon too. Smog is more of a problem in many areas of the US. And every time some politicians try to do something about it everybody screams about the costs. In Europe the politicians have data about the effect of bad air on e.g. childrens' health. In the US, they have data about the effect on the economy.
So why go full tilt towards banning lead in electronics for something that *might* be a problem (and probably making the problem worse by increasing failure rates), but not do anything about lead roofing, which is probably a far more serious risk of leeching into groundwater and also has plenty of proven alternatives?
I guess if banning lead roofing was going to increase failure rates there, the roofing industry would be all for it; more revenue for them. One of the reasons was that in many places, trash is incinerated due to lack of landfill space. Lead is the top toxin that's left over after incineration and it is hard to filter lead out of the exhaust with high effectiveness. And in the end most of what we bury in landfills comes back into the environment one way or another. Organic compounds decay; it's the inorganics that are the problem long term.
Lead is only dissolved in the presence of acids. Pure lead forms an oxide layer and doesn't dissolve in noticeable amounts. I don't know if acid rain is strong enough to dissolve significant amounts of lead from roofing.
"We already knew of the theory behind why demagnetizing CDs nets audible results. The aluminum used for the reflective CD layer is contaminated with ferrous impurities and thus susceptible to magnetizing. Ditto for the ink used for printing the label. When the CD spins at up to 500 RPM, these ferrous particles begin to act as magnets as they are moving in a -- however small -- magnetic field. "
Man, this is hard physics. Nothing that a humble EE would understand.
Now THIS is BS. There are innumerable reasons a technology, which can improve fuel efficiency in modern vehicles, might not be used. Things like weight, maintenance, reliability, etc. Don't forget fat, dumb and happy Detroit companies.
Meh. If you use thermoelements to remove heat from the CPU, you get electrical power back. I have a wonderful design that'll run your entire laptop just from the CPU heat that would otherwise be wasted by cooling. No batteries needed anymore! Investors are welcome to get in touch with me. I guess I'll have to submit the scoop to a Reuters editor.
That is what's often recommended by doctors like chiropractors. A little weird at first and you can't recline, but it's optimal for typing. Not only does it force you to use correct posture, it also causes you to move around slightly, which keeps circulation up, burns calories and strengthens the core. They are really cheap so just try it. Make sure you get the right diameter - a few inches above knee height, then pump it up so that your thighs are horizontal when you sit. And no, they don't explode. The better brands guarantee that they're burst proof.
What? You are not for IP? I like it. After all, the entire Internet is based on it. We should also have a Pro-TCP act. Then we can work our way up the layers. On second thought, why not simply make the RFCs law?
How do you verify that a file is or is not pirated, exactly? You don't. Obviously if there's a copy of the file out there on P2P you must have downloaded it from there. Just run some MD5 or SHA1 hashes and anyone who has a matching hash is guilty until proven innocent.
Do you think many representatives, senators or industry bosses read Stephenson? Somehow I doubt it. They probably think more along the lines of panem et circensis, where both is copyrighted.
Not to mention freedom of speech... You say mostly what you want in public without having the FCC or some moralists on your back just because you used some choice words.
Development might grind to a halt, since no one could easily validate the source for various underground successor projects. Assuming the project is hosted in a country that is affected by the government(s) you're talking about. And if that's a problem just use P2P and/or an anonymous overlay network.
I don't get it, why would the government want to shut down a sci-fi/fantasy publisher? They're giving away free e-books, which obviously makes them part of the anti-**AA/copyright terrist plot.

Sounds a lot like Knoppix on a stick to me.
I have one on my keychain.

You just don't know the science behind it:

Easily fixed. All you need is a few RC cars.

Lime in beer is a sacrilege. It should carry the death penalty. At least.

If there's anything you can do that can't be construed as criminal if need be, the laws need to be fixed.
