KVM does not need to do para-virtualization, but it can do para-virtualized I/O to get better performance (see virtio).

I believe he meant that the hypervisor itself is a forked version of Linux. Sure, you can run any guest OS you want on both Xen and KVM.

Correction: Red Hat aquired Qumranet, the inventors of KVM (link), so Red Hat is abandoning Xen in favor of KVM as well.

Yea but properly use them? Today, the OS uses the cores in a pretty stupid way, and you end up with data structures being shared by cores, and so you need to lock them (expensive) and copy data between cores (expensive).

Once the operating systems handle them well, and application programmers are more aware of these issues, things will be much better in multi-core-land.

Does the Istanbul have Extended Page Table support like Nehalem does? This is supposed to give a big performance boost to virtual machines, though I haven't seen any hard numbers. Any info?

So?

Not quite there yet, but I saw a nice Israeli UAV on Futureweapons. You launch by hand, can select a location to "hover" over, and then press "return home". It flies back on its own, points itself in the direction of the wind, and glides down.

Or maybe you're just posting a negative review because you work for the competition? :-)

Good thing Slashdotters don't read articles. Otherwise we would be an accessory to linking an article about linking articles.

That's only if a human needs to interface with it directly. If the tiny computer had networking capabilities, you could access it through that. How about a pre-programmed computer that collect data from their surroundings? They could be injected into a person's blood stream for health monitoring, spread around the worlds oceans, and even dispersed in the atmosphere. And that's just one direction that you could go with this. Don't limit your thinking to the computer that you're sitting in front of.
