Three choices, but none of them gives the optimal solution, which is unmodified guest OSs on processors lacking specific hardware support.
This is apparently hard or impossible on many i386 processors due to the difficulty of intercepting certain instructions. But since Linux updates the processor microcode at boot time, would it be possible to modify the processor microcode to change the way the offending instructions operate ? (just invalidating them would proably be enough)
You're wasting your time - every time this is discussed people submit great and/or obvious ideas for improving Slashdot. Not once have any of them been taken up.
Here's my obvious and great idea for improving it: have a period after the the arrival of the story on the front page in which people are not allowed to post. That would go a long way to minimise the idiot postings from people who DNRTFA.
Is there a reason why it's called a NOT gate rather than XOR ? Is there some quantum wierdness that makes the thing asymmetric and causes A-inverts-B to mean something different to B-inverts-A ?
IIRC, quantum computers have one killer app, which is that they can simulate other quantum systems (i.e. Stuff). If you try simulating a lump of high temperature superconductor on a classical computer you won't get very far, but on a quantum computer you just might.

more cosmic rays get through. Meaning warming. The only tiny snag with this theory being that the only effect anyone has claimed for cosmic rays is an increase in cloud and thus a decrease in temperature.
You download the package and build the package yourself. Building a package is almost exactly not what I mean by easy installation - and the fact that software authors so rarely provide packages on their websites suggests that they don't feel it's a trivial amount of work either.
Then you do the same thing that you do on Mac or Windows. I don't think I've ever seen a Windows program that didn't run within a couple of mouse clicks.
That's all very well if I want a package that's in the repository, but if I want one that isn't ? Or a version that's newer than the one in my distribution ? Then unix installation is sheer hell.
On the subject of Global Warming, allow me to be the first Canadian to say YES, YES, AWESOME, FUCK YEAH! Say, that's some nice climate you have there buddy ! And only a few hours tank drive away !
Could someone help me out here - are these people trolls, shills or tards ? Because it's quite hard to tell on Slashdot. I'm even beginning to wonder if it's the staff, trying to drum up pageviews.
I thank God the scientists keep looking for patterns and physics to try to explain what we see in the geologic and solar record & current observations of the sun, as that is the ONLY WAY we will ever have a chance of really knowing what long term cycles are caused by.

But that is not convenient for politicians who want power, and bureaucrats who can manage whole new divisions of government if they get funding to try to act on something with the citizens money, when there is only speculation as to what is going on and to what degree, let alone whether we can actually do anything about it.
Yes indeed. It brings me to tears to think of the better, finer world we could have had if only the World Government hadn't risen to power on the pretext of controlling the Milankovitch cycles.
If only the voters had the same firm grasp of reality as the people who marked you +5 insightful.
Ye gods. Just what sort of fucking ultra-morons have we got reading slashdot these days ? People who think a megajoule is a huge amount of energy, rather than enough to boil a kettle ? People who think we need to give ships nuclear reactors to give projectiles the energy of "a Ford Taurus at 380 mph".
I've been following global warming for a long time now doing a lot research on the side for the last couple of years. Here are some facts about global warming. Some of which you hear and don't hear from the main stream media:
1.) The world appears to be getting warmer with many computer models showing an increase in global temperature.
The word you're looking for here is "thermometers".
3.) Apparently, the Earth magnetic field has decreased by 10% in the last 150 years (source: http://www.space.com/scienceastronomy/earth_magnet ic_031212.html). I'm an electrical engineer and during my studies in particle physics, I learned that a particles velocity can be affected by magnetic fields. I believe it's possible that more of the Sun's radiation is penetrating the Earth's magnetic field due to it being weaker. If more radiation hits the Earth, shouldn't that also increase the overall temperature of the Earth and can global warming be attributed to this?
No, obviously not. The temperature was falling throughout those 150 years and has only started rising recently. The only correlated factor is CO2.
Complete crap. We have absolutely no idea what the temperature history of the other planets is and so we have no way of drawing any conclusions from any changes we see.
6.) The United Nations found that there is more Methane produced from livestock, which raises global temperature greater than CO2 by a factor of approx. 20, than any human caused CO2 combined (source: http://www.fao.org/newsroom/en/news/2006/1000448/i ndex.html)
The article you linked to says that CH4 only amounts to 18% of CO2-equivalent emissions. Since the lifetime of CH4 is only 12 years, the cumulative effect is smaller still.
How can you explain the recent same climate changes on different planets? I doubt it's all those cars being driven there.
See above. However, since temperatures on Earth have only started rising recently, and we've been monitoring the Sun's output longer than that, we can be sure the reason isn't a change in the Sun.
Is it possible that the warmer temperatures that Earth is experiencing are caused by cyclical natural phenomena? What about glaciers in Greenland that have been shrinking for 100 years (source: http://www.breitbart.com/news/2006/08/21/060821191 826.o0mynclv.html [breitbart.com])? Also, how do you explain huge ice ages on Earth? Were thse caused by huge carbon emissions or was it a small natural climate cycle that just happens? Were those climate changes, which are no doubt more extreme than what's going on now, caused by the combustion engine? I don't have answers and everyone seems to have an opinion including a Nobel laureate who says the answer is more pollution (source: http://www.cnn.com/2006/TECH/science/11/16/smog.wa rming.ap/index.h
Wrong again. [...]Submerged ice melting in water leaves the water level at exactly the same place.
No, Wrong Again Again.
When you melt ice it produces a volume of water a few percent smaller. But this volume would (were it not so runny) still have a large part above the [sea] surface because because sea water is much denser. So when
it melts, the water level will go up.

My apologies. It was actually the guy below I was thinking of.
*Sigh*. On the internets, no-one can hear you sarcasm. I'll remember next time.
Everyone knows this one already, right ? But just in case.

Logic....hurting....brain....
1) Do what thou wilt
2) See above
3) GOTO 1

Apparently this gun will fire a Ford Taurus at 380mph.
Does anyone know if Clarkson or Hammond have expressed an interest ?
