Yes, in practice mining mostly follows price, but it's still not quite that cut and dry.
Miners also need to sell bitcoin to recoup operational costs. They influence the value of bitcoin by being an active trader and setting limits to their sale price.
Current price influences future mining. Past mining influences current price.
Well, theoretically the value of Bitcoin would be a function of energy costs and mining difficulty, but that hasn’t happened in practice, and would still be volatile anyway.
It's an okay-ish alternative to a password, but if we're going to use cryptographic secrets for auth, I'd hope to see more of a handshake and challenge-response involved.
As it stands, anyone who has access to a private key momentarily can generate any number of tokens for use, practically indefinitely (just sign a timestamp for every second for the next N years). This system is open to replay attacks as well.
It also glosses over the entire problem of trust establishment, cert revocation, etc.
> Heartbleed (and all the other serious memory exploits) required a great deal of skill and a lot of luck to exploit, and in return you either don't get a remote execution, or you get a very tiny chance of a remote execution.
Heartbleed wasn't about RCE at all. It was about memory disclosure -- memory that contained secret signing keys. The fallout was that keys needed to be revoked and rotated.
Reading out memory and extracting the secret keys was actually pretty simple. There were multiple POCs available.
If I drove my manual better, I could probably achieve that, but spirited driving made me replace everything twice over in 100k miles, with a third needed soon. :(
Acceleration does not waste energy (other than speed related things like wind resistance). This is a myth that is perpetuated without merit, but probably because it's typically associated with overall aggressive driving, which implies bad braking habits.
Max efficiency is typically near peak torque for internal combustion engines [0]. For EV's, electric motors are actually most efficient at higher RPMs [1].
Fuel efficiency can be measured by breaking habits alone.

This doesn't make any sense, unless very, very specific bounds are put on the interview questions beforehand...
Without that, what is a candidate to do? Memorize all known data structures and algorithms?
> a jury of random people is probably the most qualified way to determine the question "would average people see these two things as substantially the same."
A jury of random people can be confused and then convinced by lawyers. That's the way they like it, and that's the problem with jury selection - they chose people specifically because they are not knowledgeable.
