Yes, but.

In the case of AT&T there were real physical limits to the number of calls that could be made from A -> B, and if the last slot was used by a hacker, there was one less slot for a paying customer. Most of the time there was overcapacity, mostly because AT&T did overcharge business customers, so they could afford to overbuild.

Still not getting it.

Over here, broadcast television doesn't have anything like a "Listen Live" button. It's strictly one way.
Exactly what buttons might one accidentally click on, on television?

In the US, there is "free" commercial broadcast TV, and paid subscription TV over closed cable. Internet TV is either free or paid subscription. For the paid stuff, you have to sign up for an account, and although there are ways to circumvent it, if you don't pay, you can't watch.

I was aware that British broadcast television was licensed, rather than a subscription. Is there a similar model for BBC Internet TV?

Did Gauss "put forward a multitude of propositions which one could neither prove nor disprove"?

Especially now that we have very fast computers, it seems like the false conjectures would be quickly disproven, and the true ones might take a bit longer. If we eliminate needlessly complicated conjectures, are we left with only "interesting" ones?

That's why you need to be a lawyer to understand this. It's possible that for a given State or Federal law that the owner's intent is what's important, not their implementation. And the intent of the defendant is also a factor.
So, if the owner intended the site to be secure, and the defendant intended to break that security, the actual security might be irrelevant.

IANAL, YMMV, talk to a lawyer in your own state for specifics.

A regular car probably has some place where exactly 1 logic 1 or 0 can be sent to unlock the door, but it's not unusual to have a system that first requires an enable solenoid to be activated, then simultaneously the unlock solenoid actually moves the bolt. (Mostly military stuff)

The solenoids also take a bit of current, so if the logic controller is well shielded and takes a stream of bits to open, your system would be fairly secure against EMP type attacks, even if the solenoid isn't well shielded. You don't want your doors unlocking every time you pass a Semi with a 1kw linear amp on his CB rig.

Please explain this to the people on the other side of the pond.

There's a web site where you can get information, but only if you click a certain place are you liable for a fee? Why doesn't the click take you to a login page that verifies you have the license?

A stream of particles traveling above a surface in uniform motion. A vehicle hovering above the surface could only be pushed as fast as the stream is moving.

A wheel on the surface moving at the same speed as the surface isn't all moving at that speed, even if it's center of mass is. The part that touches the surface is stationary w.r.t. the surface, and the top is moving faster than the center speed. If the stream of particles is directed at the center of mass, the most it could be pushed is up to the speed of the particles.
If the stream is directed more to the bottom of the wheel, the center of the wheel could be pushed faster than the stream of particles is moving.

I'm not saying that this is what is happening, just that it could be.

Doctor Who, Gregory House, and Sherlock Holmes are all the same character, with different occupations.

A difficult to work with genius, almost always with a companion. (On "House" they made the companion a team.)

Anything that moves in response to commands is going to be more interesting that stuff that just sits there. Start a robotics curriculum that can be expanded as you find more resources and sponsors.

Throw in a 3D printer and there will be all sorts of interest.

A great idea, but if you implemented it, companies would hack around it. Perhaps by adding another layer of lawyers invoking client privilege, or binding arbitration by a secret panel.

When companies sue each other, neither wants the results public. When a person sues a company, the company will offer them more money to stay quiet, than they can get from the original lawsuit. (once you figure the likelihood of winning & the time value of the money) A settlement keeps most of the facts away from the courts.

Stronger whistleblower protection and a better FTC would help shine light on corporate malfeasance. A law that made silence contracts non-binding would be bad for a few individuals, but good for the rest of the country.

People need privacy. Corporations, not so much.

Everything is possible if someone else has to do it and pay for it.

Movie companies still own movies that have child stars. What's special about entertainment contracts that can't be applied to PayPal contracts?

Kids write, record and perform songs all the time, the the record companies have found a way to hold them to contracts. Ditto for kids that appear in films. What does Nashville and Hollywood know that PayPal can't figure out?

They shouldn't wage an expensive a war against nature.

You shouldn't spend too much just to stay alive.

I will spend whatever it takes to stay alive and comfortable.

Substitute anyone for "They", "You", and "I".
