No, you can't use a BUD C-band for Ku-band reception because they resonate at different frequencies. They make large Ku-band dishes, but you probably don't have one. A 36-inch Ku-band dish will get anything you need to get anyway...but I realize you're trying to find a use for that huge hunk of steel.
3-cylinder engines suffer from the problem that you can never get equal numbers of cylinders going up and down at the same time, so they have a primary imbalance. That results in additional weight and complication necessary to isolate the engine vibrations.
Personally, I'm all for ridding the world of all fossil fuel consumption within the next month. Once we have an economic, social, governmental, and population collapse (in that order), perhaps the world will re-form itself into something better...or descend into The Road Warrior, which would be cool too.
That's unfortunately part of the problem. I've dealt with plenty of "justice" people, from District Attorneys to Police Officers, that think they know what technology is all about. This judge is confident in her understanding of how computers work, and no justice-evading "thief" is going to outsmart HER. I'll bet the judge can't even program her VCR.
I don't think that OPEC is a free market; but they only produce something like 45 percent of world oil. In any case, OPEC has very limited control over its own pricing; its producers regularly flaunt overproduction in violation of quotas...that's the market at work. When oil prices neared $80 per barrel, it was interesting to me how many long-dormant oil wells started pumping again. That's in western Illinois, where oil production hasn't been serious for 30 years.
Still, I'm very glad to see the biodiesel plants starting up...production of any sort of energy will only help the world along. I'm not opposed to things like that...but only if the market demands them, and not if a mindless government committee demands them.
I think that "costs of pollution" is a nebulous figure. How do you monetize pollution? Do you count the cost of a hurricane that hits New Orleans, and blame it on OTR truckers? The costs of pollution are already passed on to truckers...if they produce global warming, then it will certainly bother profitibility at some point, and the market will react. If they produce noxious gases, then they will be sued by sick employees, or perhaps simply have health costs passed to them through taxes. The point I'm trying to ultimately make is that government's "visible hand" is a very poor and heavy substitute for Adam Smith's "invisible hand."
The problem is that to get all of this wonderful clean environmentally-friendly energy you talk about requires the shackling of the free market. The free market should be determined by prices, supply, and demand, not an amorphous government committee made up of elite eggheads. "Entire new industries" will be opened up, but they will be industries in the states of well-connected congressmen, and they will not be well-managed industries if they are created by the government. The goals of higher energy-effeciency are laudable...but if they were true, the free market would be using them NOW. Look at "hybrid" cars...if they were really better, every over-the-road trucking company would convert tomorrow.
I have used RHEL5 and FC6, and had no stability problems.
Obviously your requirements are higher than mine, and your datacenter larger than mine. I salute you.
Well, I've done numerous tests of live migration, and it works for me. Do I know something they don't? I don't think you can say either way. Perhaps on somebody else's network, it might not work. But I've done migration under heavy load and not had any failures, zombies, or crashing of Dom0. I had to clarify the 6ms delay in another post. Here's the way I put it, simplified because I screwed up the formatting...
ping...64 bytes from xxxx...5 ms ping...64 bytes from xxxx...5 ms ping...64 bytes from xxxx...11 ms ping...64 bytes from xxxx...5 ms ping...64 bytes from xxxx...5 ms
The bump to 11ms was the transition between real machines.
We use it because we like to have lots of machines doing different things at different times. The developers have wild ideas, so we give them what they want as far as an OS, and create and destroy as necessary. We keep the migration as an option in case of failure; we don't do it on a regular basis.
Maybe I should clarify some things, since I'm on Slashdot and can't expect people to take things in context. You are pinging an active machine that is to be moved. Here's what it looks like:
64 bytes from xxx.xxx.xxx.xxx: icmp_seq=1 ttl=64 time=5.01 ms
64 bytes from xxx.xxx.xxx.xxx: icmp_seq=2 ttl=64 time=5.21 ms
64 bytes from xxx.xxx.xxx.xxx: icmp_seq=3 ttl=64 time=5.10 ms
64 bytes from xxx.xxx.xxx.xxx: icmp_seq=4 ttl=64 time=11.10 ms
64 bytes from xxx.xxx.xxx.xxx: icmp_seq=5 ttl=64 time=5.01 ms
64 bytes from xxx.xxx.xxx.xxx: icmp_seq=6 ttl=64 time=5.31 ms
That bump in latency was the transition. You have officially gone from one machine to another. That's what I meant by 6ms. I have tested this over a range of CPU usages, and it's pretty consistent, at least on my network (full gigabit Extreme switches, newer Dell 4-CPU servers, SAS drives, lots of RAM.)
My company is currently using Xen on something like 40 "virtual machines" on 6 "real machines." Works almost flawlessly. Runs heavily-used multi-gigabyte MySQL databases and Java web apps without complaining. You can move virtual machines between real machines while they're under load, with a 6ms delay. If a developer wants to try something weird, go ahead. If you hose the system, I'll just re-image it and have you going again in 5 minutes. There's nothing wrong with Xen at all, if it's done right. It's ready for the datacenter, because we use it now.
Here's what I contend: Chinese coal fires produce 360 million tons of CO2 per year...more than all cars in the United States COMBINED. We need to work on the big stuff before we start enacting laws to force people to ride bicycles to work. Or what would you suggest to get rid of CO2 production in the US?
Not that I broke it up into paragraphs, but...
"The Chinese fires also make a big, hidden contribution to global warming through the greenhouse effect, scientists said. Each year they release 360 million tons of carbon dioxide into the atmosphere, as much as all the cars and light trucks in the United States."
http://www.post-gazette.com/healthscience/20030215 coalenviro4p4.asp
"Stracher's research suggests coal wildfires in China burn 200 million tonnes a year, equivalent to about 20 per cent of the total used by the US for power generation."
http://www.newscientist.com/article.ns?id=dn3390
"Carbon dioxide emissions from personal vehicles in the United States equaled 314 million metric tons in 2004. That much carbon could fill a coal train 55,000 miles long--long enough to circle the Earth twice."
"Although SUVs currently trail small cars as sources of carbon dioxide emissions that contribute to global warming (67 million metric tons or 21 percent of all U.S. auto emissions), they will soon be in first place and will remain a leading cause of global warming on U.S. roads for many years."
http://environment.about.com/od/globalwarming/a/au toemissions.htm
So you can see...if we got rid of coal fires, we could get rid of 360 MILLION tons of CO2 per year...that's 5 times as much as every last hated SUV in the United States. Imagine the joy of countless Al Gore-types if we suddenly passed a law condeming every Hummer, every Suburban, every gas-guzzling pickup to a junkyard...and yet we ignore something 5 times as large. Like I said, all of the political work that's going on to encourage things like carbon trading and the banning of SUV's has one thing directly in its sites...MONEY. There are carbon trading floors already set up, and the government is ready to dole out trillions worth of these "credits" to politically-connected people. Make no mistake...there will be little environmental impact, because a huge amount of CO2 is coming from sources other than humans.
Nobody ever pays attention to the coal fires. If it were REALLY about limiting carbon emissions, we would go solve that problem. ONE of those fires puts out more CO2 than every automobile in the US, and they are burning all over the world. It's not about "saving the planet"...it's about establishing a stock market for carbon trading that will make a few well-positioned people trillions of dollars.
Look up the case of Bill Cheek sometime. He was an electronics hobbyist producing a very simple box that sliced up PSK data streams so, for instance, a hobbyist could decode police dispatching systems. He produced them for sale. With absolutely no warning, FBI agents raided his house and took practically everything he had to make a living, from computers to paper records, and refused to let him touch them at all. The production of data slicers was not illegal, nor was it particularly serious. It was basically people in the government harassing someone. The government dragged his case out for months, until he died of lung cancer. He was saddled with thousands of dollars of legal fees, and eventually his wife was too. There is no way you can stand up to the government; they have unlimited resources and lawyers on tap. It may be a moral imperative, but that has to intersect with practicality for the individual, too.

Obviously we need massive government subsidies and laws that compel people to buy their products.
You like to eat, don't you? Farm tractors run on diesel. It's as simple as that.
Most cordless phones are now digital 900 or 2400MHz. Unless you can decode that stuff on the fly, all you're going to hear is scratchy noise.
