No. It's for when you'd want a VM to run a similar OS or separate hardware but without the overhead of either. A full VM has far more overhead and in some situations all you really want the VM for is put a bunch of applications in a separate space with their own IP address, so that's where you use a zone. A very similar thing is in development on linux and is called a "container", which is also how zones started to be described a couple of years ago.
Physics gets in the way and thermal power generation is at its best when large. Nukes are a special case where all that exotic stuff required needs to be done in bulk to justify the infrastructure needed to get any of it at all. While a large nuclear plant theoretically gets a vastly better value of $ per MW than any of the other alternative energies the need for a lot of capital at once and the need to sell the electricity in large volumes makes it unattractive to investors which is why so few have been built since the 1980s. So while it would be nice to have a magic cheap little nuke we only get two out of the four since magic doesn't exist to give us the other three - cheap or little, where cheap is per MW and not for the enormous thing cheapskates do not want to pay for even if it's going to deliver a very good value of $/MW when it gets completed in a decade. More expensive per MW windmills are available far sooner and so much easier to pay for that popular short term voodoo economics judges them cheaper than something with a better return in the long run.
Holland built a tourist industry around those "horrible blights on the landscape" before you were born so I suggest you try harder and try something informed by reality and not what some pathetic political hack has told you to repeat.
Ah - the guy with not even a high school level understanding that pretended to be an electrical engineer is back! You can make up for that lack by looking at a weather map and trying to identify a day when there is no wind at all over a region large enough to be covered by a national grid - or pretty close to continental in the case of the USA. Ask a small child to help if you like to get an answer about "unreliability of wind". It's always blowing somewhere and not just out of your rear to provide misinformation like the post above.
Yes, ZFS will eat whatever memory it can find and give you your files faster in exchange. It's amusing when you grab a file from two days ago and it arrives faster than disk speed.
By default Vista did things very, very wrong initially. It couldn't even log into an MS domain without downloading and running a fix from the command line. That was very amusing at a time when MS fanboys were blasting linux for having a command line at all. After a while and a lot of updates it settled down, using far less memory, doing file copies at full speed and so on. There's still a couple of Vista systems in my workplace used by some people that did an end run around IT to get them - they are sort of usable but make Win7 look like a work of wonder in comparison.
Now here is why the above example may be relevant to you - several popular image editing programs do a lot of operations on the working data from your current image on disk instead of in memory no matter how much memory you have. Put it's cache on ramdisk and some operations speed up by an order of magnitude or more and let other operations happen. I've seen a machine lock up for twenty minutes rotating a large TIF file despite having a lot of free memory because it was thrashing the disk flat out.
In my workplace there is a rather braindead application that sorts a lot of data on disk instead of in memory (closed source - otherwise would have been fixed ten years ago), even when the dataset is a lot smaller than memory. So we fed it a striped set of disks. Then we fed it an SSD. Then we fed it a couple of striped SSDs. Now it's using a RAM disk and it's an order of magnitude faster than even striped SSDs. Instead of going through a controller and other bottlenecks - bang - in and out almost as quick as sorting in memory. Several hours down to a few minutes. The RAM disk is 200GB of 512GB of onboard memory though:)
but would he have foreseen them any better than Bush
He turns up for work, so yes, most definitely - just as any other President before baby Bush would have.
You see, despite people calling the President...
You see, despite people calling the CEO of GM the carmaker in chief, he doesn't actually weld up those chassis. Does that inform you of how idiotic some of the things written above are? It's not your fault since a lot has been spent on PR about how some sort of superhero at the top is needed instead of the head of a vast org, but without a working head the vast org gets manipulated just as it did under Clinton and baby Bush, under which it all fell apart eight years after Clinton had left the building. If Clinton alone was responsible why didn't it happen earlier and why didn't baby Bush take steps to deal with it on those days when he was not on vacation?
With respect, I was teaching engineering students about corrosion before this site even started so unlike you I am not making shit up. The tiny amounts of chlorine required (wikipedia says 0.5 ppm to 2 ppm you utterly lazy creature), as there is in the drinking water in some places, fail to do measurable damage to stainless steel fittings that they come in contact with when used as drinking water. It's nothing remotely close to the amount of chlorine that is in seawater which attacks many different types of stainless steel. It's nothing remotely close to the concentration in a swimming pool. Look it up instead of making it up - that's what I did but I looked it up first in 1990 and have read a bit since. Now it only takes seconds to look it up - wikipedia has it FFS. So why do you wish to spread such misinformation? Does it give you some sense of power over the kiddies to make them believe something you just made up? They should look for themselves instead of falling for shit from you or taking my word for granted.
Yes, but what did Bush do about it? Blame it on Clinton if you like (also an example of influence on the economy) but Bush could have done something between 2001 and 2008 when it all fell apart, which is my point about how having someone asleep at the wheel is a poor influence on the economy.
I disagree. That WWII bury them in bodies attitude was still very much in place among the leadership in the 1980s as shown by how the USSR Afganistan campaign was run among other things. It looks like they expected to lose a lot but keep on going in the minor cities. Remember that Stalingrad lost more of it's population than Hiroshima or Nagasaki.
Look up imply and read the post you wrote again. You are suggesting we should give people a free pass due to incompetence - which implies a total lack of confidence in the armed forces.
Translation: more than enough to damage the equipment.
WTF do you get something as utterly ridiculous as that from? If you made it up - why? The difference is several orders of magnitude. The drinking water in my city has a concentration of chlorine several times higher than this bacteria can stand, and domestic bleach is far more concentrated again yet still unlikely to "damage the equipment".
plus, it's an added cost, both in time and materials
True, but that's life when you are squirting a deadly bacteria laden aerosol into areas where people are breathing. Some expense to avoid doing that is considered tolerable.
Examples are being able to have solaris8 and solaris9 zones on a solaris10 machine with each zone having a different network address without the overhead of actually running three different operating systems. A trivial use is running legacy software and preventing copy protection software locked to an interface address or hostid from colliding with the same poorly written copy protection software for licencing another application running on the same machine - as far as it can see it is not running on the same machine.
Come off it - if his mythical week involves only getting four hours of sleep every work night that implies not being able to shift some work onto the weekend and get more sleep. It's bullshit and if you cannot see it then I have a bridge to sell you.
Zones are like having a virtual machine without the overhead - a step beyond jails and similar to containers. Among many other things they are a good way to run legacy software from a collection of old machines that need different libraries, different hostids etc.
The problem with civilian nuclear is that community outrage about safety resulted in the cheap option of hiding safety issues instead of dealing with them.
Actually it does in the case. Chlorine in the water kills the stuff. The problem here is killing the stuff and walking away instead of putting chlorine in the cooling water and keeping up the chlorine levels. According to a microbiologist I spoke to about this some years ago the amount needed is less than is in drinking water in some places - enough to taste awful but not enough to make it unfit to drink.
Gnome3 is so slow that Wayland fanboys use it to to try to prove that remote access via X is slow. It's only accelerated video cards that make it usable on the desktop. Try to put it on another screen and that crutch gets kicked away. Meanwhile plenty of workplaces are using Gnome2 remotely as if the applications were on their desktop (eg. in RHEL6/CentOS6)

A cache doesn't help much when the stuff changes, such as in a sort or image transformation operations.
No. It's for when you'd want a VM to run a similar OS or separate hardware but without the overhead of either. A full VM has far more overhead and in some situations all you really want the VM for is put a bunch of applications in a separate space with their own IP address, so that's where you use a zone.

Very different so superior for some situations but not others.
For example a zone can have it's own network address.

By that time the Pentium Pro was being designed due to 4GB per CPU not being seen as enough and a 64 bit SPARC was available.
