Re: Iran is building a Fake Aircraft Carrier

As far as IDing a carrier, anything that big going that fast is a US carrier (if they aren't going fast it might be a supertanker, or maybe the carrier doesn't want to make it obvious). Same logic in telling an airbus from a F-14. It is very difficult to judge the size and speed of a ship from the ...

Re: What determines the pricing of hardware?

At the very high end (eg. Intel's "Extreme Edition" CPUs), the price is determined by how much they think people are willing to pay, rather than on performance or production cost. For example, the Intel i7-4960X is only about 5% more powerful than the i7-4930K, but costs twice as much.
