    If Tor is running on the local machine, yes. Normally you don't use a remote HTTP TOR.

    Classical proxy server HTTP sends a normal HTTP request, but always sends it to a particular IP. Normally you look up www.slashdot.org and send the request there. The request includes a Host: header always, so instead of GET /index.html HTTP/1.1 to Host: www.slashdot.org on 216.34.181.48, you send that to 10.10.100.50. 10.10.100.50 uses the Host: header to DNS look-up www.slashdot.org and sends the exact same request on.

    It's not that simple. If an independent steel mill operates favorably with an independent construction company, you have what is considered illegal trust activity. This is no different with the same shareholders on the board; just the burden of proof is lower because of obvious conflict of interest, rather than implied collusion. If they operate independently without favoritism to anyone, then it's not considered trust activity.

    So you see, if Tesla spins off Tesla Dealerships, they could be put under scrutiny for vertical monopolization; but if the same shareholders found Nicholai Tesla Dealerships without collusion, kickbacks, or whatnot--with just the normal business operations of any other Ford or Mazda dealership--it's perfectly legal. It'll draw scrutiny, but it's not illegal per se.

    In a mechanical system, you can have things like viscous couplers or torsion differentials. The wheels will spin at the same speed, but if one encounters less resistance then more power will move to the others. A single power unit supplies power input, which is then distributed based on the laws of physics as applied to a complex mechanical system. Gears and metal poles are lossy due to heat from flexing, compressing metal; viscous couplings are obviously more lossy because they're non-solid and thus the working fluid is experiencing far more deformation than metal.

    In a hub layout, all those inefficiencies go away. Computers perfectly apply the correct amount of torque at the correct rotational speed directly to each wheel. For a given RPM, the motor will simply spin at no torque unless there is resistance, at which point it will draw more power to retain spin speed.

    Unless... your calculations are slightly wrong. And the motors have loss by heat--which they do. And the computer has to calculate when to back off power to one free-spinning motor which is now heating up and spinning the wheel too god damn fast, but only after taking a sample.

    Hub motor efficiency gains aren't ungodly massive; they're small, and they require perfect operation. They also require additional (powered) sensors and computer number crunching, rather than passive mechanical systems which simply cannot function in any manner besides "distribute power correctly" or "fail completely because the system is broken". Drifting sensors, poor sampling, and just the need to get enough of a sample to make a statistically significant analysis and adjust power output per wheel all rob hub motor systems of their theoretical maximum efficiency. The first of these is of particular practical importance: it's extremely easy for this system to be out of spec and inefficient without the end user knowing or caring. The rest are engineering challenges.

    All of these potential failures are multiplied by the number of hub-powered wheels. An entire drive train system--a hub motor, its connection to the wheel, sensors, power connectors, regenerative braking mechanisms, and so on--must be duplicated four times to get all-wheel drive. With a single power unit in a mechanical system, you only need to build one drive train, which is simpler and only needs to be incrementally improved in very direct and simple ways. No improving computer code for the average case while trading off the better case; no attempting to get sensors to get more precise data, then trying to factor that improvement into the rest of the control system. You use better alloys, better machined gears, you use what you learn from further research to tweak the design so that it couples and transfers power more effectively and reacts more quickly and immediately to slippage.

    The big driver for hub motor vehicles is all the things you can do in theory. Modern traction control and ESC applies braking force to individual wheels, whereas you could just back off the hub motor... or apply braking force by the regenerative brake. But that begs the question: aren't you using the same computer control programs for regenerative brake applied traction control as you are for hub motor regenerative brake traction control? And then of course those benefits essentially come down to the corner case of driving in terrible conditions, which is inefficient as hell anyway--and your efficiency gains are minimal.

    Lots of funny theory, lots of "with X we can Y", as it has always been. One of the big pushes with Firewire was that we were going to have revolutionized home entertainment: you would have abstract equipment with IEEE1394 ports, plug a speaker into the VCR, plug another into the TV, subwoofer into a receiver deck at the back of the room daisy chained to the DVD player, and daisy chain rear room speakers off that, and all these devices would find each other through these arbitrary connections and unify themselves as your home theater. That was being heavily advertised in home theater shops for a while, but it never happened. All these things you should be able to do with your iPad never materialized. The XO Laptop hasn't met its potential yet--it has revolutionized nothing. Same with hub motors.

    There's one motor, a direct drive linkage (no transmission), and differentials. Hub motors require all kinds of computer control, with associated high chances of fault that could much more easily lead to loss of control or efficiency. Hub motor efficiency is kind of like video poker: perfect play for 3 years straight will net you a profit, absolutely, no question you will beat the casino; the profit is small, and a single small mistake will set you back about 85 years. It only makes sense in a motorcycle, where you have one rear wheel hub motor.

    Maybe. A good, readily-accessible education system is great for businesses who want to access an abundant supply of off-the-shelf talent at low, low prices. It's not so good for the supply, which is somewhat perishable.

    The supply is vocational graduates.

    When Arthur Anderson was in business, accounting was big business; a lot of students went to school for accounting, got jobs, made a lot of money. Left to its own devices, the market would have eventually saturated, and a lot of accountants would have come along with no jobs--the ones who did get jobs would be cheap, low-salary accountants. As is, Arthur Anderson collapsed after Enron, flooding the streets with accountants; this accomplished the same: starving, worthless, jobless accountants everywhere.

    The US had a nurse shortage around the early 2000s. Nobody wanted to be nurses. Since nurses were so rare, salaries became high. It is well-known that this created the nursing bubble, in which many students went to school for nursing. Short years later, nurses were worth $40k with a master's degree; most couldn't get jobs because there were far too many nurses.

    We did the same with Web developers, programmers, and most IT. Runaway investment in these jobs because of the high demand and the high salaries soon lead to a cycle of many, many IT graduates coming out of college ready to go into programming jobs and network administration and not able to find any. The ones that did could net $50k.

    So in the end we have all these students who are simple resources that companies could bring in as entrants, shift low-skill tasks onto as a way to free up high-skill labor for more high-skill demanding tasks (Miyomoto Musashi, Book of Five Rings), and pass more skill-intensive tasks as they train the entrants into high-skill labor. Instead, the students go out to train themselves on their own investment, and then hope that the skills they acquire are still in demand--often they're not.

    This is good for businesses, in some short-sighted manner: labor is cheap, readily-available in certain sectors, and so on. It is bad for entrant labor. It is actually bad for business when demand shifts onto new sectors, because they must wait for entrant labor to saturate the market with skilled workers before they can pursue new business strategies--and of course the entrant laborers continue to over-saturate the market past that point, reducing their individual value and increasing the unemployment (Failure) rate.

    This is economics, game theory, speculative investment, all rolled into one. I'm sorry if you're not a polymath, but take my word for it: it's complex and the naive solution is harmful. Too much education availability is a poison.
