Well, duh.

That's because, when the autopilot fails, and the humans can't figure out what to do in a situation where the computer can't figure out what to do either, and fly the plane into the sea, the cause of the crash is listed as 'pilot error'.

If you are talking about AF447, then it was pilot error - those pilots should have easily been able to determine the situation and recover the aircraft. Instead, they didn't follow procedure, did exactly the opposite of what they should have in that situation (as defined in the flight operations manual) and crashed the aircraft.

The original issue that caused the autopilot trip would not by itself have led to the stall that ultimately caused the crash - that took pilot intervention.

If Aereo simply sent the received signal, unchanged, unaltered, and as-is to your device, chances are they wouldn't have ended up in court. What they actually did was reencode the signal and rebroadcast it to you. Entirely two different things.

  And its also why your contrived example falls down. Because they didn't run a wire which carried the same signal, they altered the signal.

Who is going to be fined? (I assume that is what you meant) The people doing the manipulation, so the people aNonnyMouseCowered allege that are manipulating the market. Who would do the fining? The SEC, the FCA or another countries financial authority. Wouldn't take much for them to do it either.

Really? Its 15.54 currently here in the UK, and its already dark. And I'm not even home yet. When I get home, there's the heating to go on (gas, luckily), food to be cooked (gas hob, electric oven), the house to be lit (electric), housework to be done (electric), and then entertainment for the evening (usually electric consuming). So from when I get home at 17.30 to when I go to bed at 22.30, there's 5 hours of electricity usage.

And that's not counting things like night storage heaters, economy 7 power use washing machines or dish washers that can be put on overnight etc.

So yes, the bulk of our power usage (and Im not the poster you replied to) is over night.

Bankers drafts *are* cleared funds - the drawer pays the bank the sum of money, and the bank issues a cheque for that amount in its own name - once the recipient is in possession of the bankers draft, the original drawer is out of the equation, all interactions are then between the recipient and the bank. Unless something very very very unusual happens at the banks end, its a guaranteed transaction. Without the bankers draft, the drawer has no way to cancel the transaction - even if he loses it.

Debit card transactions have never been cleared funds however, as they occur based on one of several basis and can be reversed.

BACS transfers can also be reversed (had a once major UK supermarket do this with my wages back when I had just quit - deposited my wages in the morning as normal, so I drew some cash out. Came to pay something by debit card later that day and it was refused - odd as I should have had a lot of money in that account, but it had all vanished. The supermarket employer had reversed the BACS because they had "miscalculated" my end wage - infact they had undercalculated it, but instead of just giving me the difference they reversed the entire payment and ... sat on it.)

What you are describing is what I already described via method #2. If and only if they are able to add their root public key to the user's computer will their fraudulently issued certificates successfully validate.

Actually I wasn't, because you specifically said in #2 "Somehow maliciously insert their own public key onto your computer". Key there is "maliciously". No need to do that as most governments have legitimately issued root CA certs in most browsers already. Including China...

No need to maliciously insert anything, they are already there waiting to be used.

Cheques are notoriously bad for guaranteed payment - businesses would only accept a cheque if your bank also issued you with a cheque guarantee card (usually just a different design on your debit card), which means the bank would guarantee to cash the cheque up to a certain amount, taking the matter up with the writer of the cheque if it bounced. If you tried to cash a cheque without a guarantee (or a cheque over the guarantee amount) and it bounces, you are SOL and have to take it up with the writer yourself.

And cheque guarantees usually only went up to a few hundred quid.

Car dealers would typically want a bankers draft, which is a bit of paper issued by your bank for a specific amount and is treated as cash - the value is held on the paper, its not an instruction to transfer money, its an actual promissory note just like paper note cash is. Lose the bankers draft, and the money is gone, you can't get it back.

Bankers drafts cost you money to buy, and you have to go to a bank to have one issued.

Pretty much no larger business accepts cheques these days in the UK, and hasn't for several years - cheques have essentially been relegated to inter-personal transactions or smaller business (single person style businesses) because of the cost of handling them as a business.
