So thought Kim Jong-il and Castro, who closed their countries to foreign trade and have essentially brought the dark ages to their nations. Please stay away from politics, before the Tea Party gets elected and we op in for a world of hurt.
Apples and oranges. The United States is the only nation on earth that could get away with closed borders and have anywhere near the standard of living we currently enjoy. Even with China's near meteoric economic growth, pulling the US GDP out of the world market would literally kill millions of jobs across the globe. Maybe a trial run is in order? See how China likes the shoe on the other foot?
As others have posted and others sill undoubtedly post, we need more information to give you the recommendation you want. Making some assumptions from your question, it sounds like you want to virtualize your workstation. For full baremetal performance, don't virtualize your primary OS. The technology isn't there yet, but VMWare is making huge strides with their VMView product. Set up properly, you can have CAD running in a virtual machine on a server with a thin client displaying the output with very respectable speeds.
For your application, it sounds like you need something like Virtual PC or VMWare Workstation. Virtual PC comes free with Windows 7 Pro and Ultimate. That's what I use and it allows me to have two or three VMs running XP for testing and/or risky web use. I haven't tried Ubuntu as a VM in virtual PC, but I have an ESXi server running, so I haven't bothered. I'm very happy with my setup, below:
There's a lot of technology out there, so you may have to do some fiddling around yourself to see what works for you. It took me a few years to gather all the hardware together and work out how to build the software just right, but it works. I use my main rig for video (kids soccer, family vacations, birthdays, etc), photo slideshows, gaming, developing, etc, so performance was key. My setup isn't top of the line, but something close to bleeding edge while maintaining a budget. Virtualization is a tool. Find something that fits your needs, understanding each product's weaknesses and strengths and you will do just fine.
I realize they were in their "rights" legally and such to put out the neighbours fire and not his.. (from the TFA, they just sat there and made sure it didn't spread). But I mean, as a human, what the ****. Is there so little empathy?
Why couldn't they have put it out and then billed him? He probably would have been so happy he would have paid it. This reeks of callousness. What have "we" become (I'm not american, but I am a human, I think..)
I imagine that if the guy or his wife or kid were trapped in the house, they would have done something. Since it's just property, they were under no such humanistic constraint. Human compassion has to have limits, or we would go around trying to fix every injustice. So I say, "well done" on calling it right for such a tough situation.
Stellar rays prove fibbing never pays. Embezzlement is another matter.
