If every bank involved agrees the invalid signature is valid, what happens to the money?

Stealing a coin here or there from a wallet that hasn't been touched in a while would be more "practical", and for all we know, is being done now.

Anyone can audit the blockchain, not just miners.

It'd be possible to find every bitcoin not traded in the past 3 years, assert it "lost" then the attacker fraudulently claim them with the attack given, and it's possible he could liquidate after the theft without anyone noticing until he's cashed out.

It's not just miners checking the transactions.

I do understand Bitcoin, and what you are describing is impossible. Bitcoins cannot be transferred from one account to another unless you have the private keys to the account that currently holds them. It's like a signed check - it can't be transferred to another account without a valid signature.

Comment Restoring tissues and organs (Score 5, Funny) 94

I know it was demonstrated awhile back that a rabbit kidney could be cryopreserved and then restored to function.

Seriously, the longer I live, the more it seems plausible that one day it will be possible to cryopreserve a human brain and restore it to function later. One day human lifespan may be greatly extended in a way that looks like this:

McCoy: "He's dead, Jim."

Kirk: "Bones, do something!"

McCoy: "Sorry, Jim, there isn't anything I can do."

KirK: "Why?"

McCoy: "Because he's dead."

Kirk: "How do you know he's dead?"

McCoy: "Because there's nothing I can do."

Kirk: "Because he's dead?"

McCoy: "That's right."

Kirk: "But I was talking to him just one minute ago!"

McCoy: "Dammit Jim, I'm a doctor not a spiritual medium! I can't bring back the dead anymore than I can cure a common cold."

Spock: "Doctor, we could take him back to the ship, dissolve any blood clots, restore circulation, and restore homeostasis by molecular repair. He could fully resume duty within days."

McCoy: "Spock, leave doctoring to doctors! What this man needs is a decent burial."

Comment Re:"After a Year In Space" (Score 1) 58

Sigh. 11 months (340 days is a hell of a lot closer to that than it is to 12 months) is in no way shape or form "one year".

It's 0.9315 years. How many significant digits do you want on that?

(Actually given that his year in space included February 29, it might be more accurate to say it was 0.92896 years.

Comment What keeps people from just leaving? (Score 2) 114

Some of India's top IT firms ... impose the three-month notice period policy on their employees.

When I don't want to work for a company any more, I don't continue to follow its policies for three months just because they tell me to. What are the consequences for not complying, and what is enabling these companies to impose those consequences?

Comment Re:and so the cycle continues. (Score 1) 242

Individual choice is fine if all the consequences are borne by that individual.

And they should be. We have a criminal justice system to make sure that happens in the case of drunk drivers, and taxpayers should stop paying for obesity related diabetes (because taxpayers should have individual choice as to where their money goes).

Comment Not really private (Score 1) 355

It starts by abandoning NASA's expensive Space Launch System and Orion capsule, and spending the money saved on private-industry efforts like Elon Musk's SpaceX and Robert Bigelow's Bigelow Aerospace

I'm sure suddenly throwing a bunch more government money at private space efforts won't change those projects in the least or make them more expensive or anything like that.

What about the tests?

This is crypto-currency, the hot new thing tests are for old fogeys who still use dollars. Get with the times, young programmers are Agile, they don't plan and test their work, they release early and often. They release the Minimum Viable Product (minimum piece of shit they can get away with for a moment), it's illegal now to even think about corner cases and make code robust.

I don't know about ZCash, but Bitcoin has an extensive regression test suite and test mode. And test-first development is a principle of agile, so I'm not sure why you concluded agile programmers don't test.
