Try 10 times and assume that there isn't a cap after that... But he also blatantly broke the rules.

Please provide pseudocode that determines whether he used brute-force. Be sure to fully justify, with citations where possible, any violation of the zero-one-infinity rule in your answer. For example, why 10 attempts? Why not 9, or 11?

If you can do this, then your claim that he "blatantly" broke the rules might be valid. Good luck!

Serious question: how could someone determine that PINs can be brute-forced without brute forcing them? Without the ability to prove it, it's the bounty hunter's word against the website, and we already know websites will do anything they can to avoid paying.

Not a lot of storage is necessary as long as electricity is never priced below market equilibrium, which it should never be. So all we really need to keep the grid blackout- and brownout-free running exclusively on renewable energy are smart meters and lead-acid batteries.

this doesn't make it easy to navigate traffic in a busy city where you are trying to pay attention to 1000 things on the road at once.

When you have trouble paying attention to your surroundings, you should slow down to a reasonable and prudent speed for conditions. That's the law.

Comment: Re: Effect of nukes on NEOs (Score 1) 272 272

Nukes are FAR less effective in space because there's no atmosphere for the thermal energy to create a big shockwave, and there's no solid ground beneath it to amplify the intended direction of said shockwave.

So there's nothing for the explosion to push up against (Newton's Third Law). That makes sense.

IMO if you want to blow up an NEO, you'll probably want some kind of kinetic weapon akin to a giant bullet, maybe a space born railgun or something.

What's that going to push up against?

If you look at Amtrak and other train transportation within the state, they are all subsidized and still don't run at capacity.

Thank you for mentioning Amtrak. Did you know that Amtrak's only profitable line is also the only high speed rail line in the country? This is why all interstate passenger rail ought to be high speed rail.

Plus, if you think it's ONLY going to cost $68B by the time it's finished, you are being quite naive... The final cost off by almost 5X what the original estimate was.

So if we apply that same 5X multiplier to HSR, it will cost $340 billion to build HSR, versus $790 billion to build the equivalent capacity in freeways and airports. So building HSR becomes $450 billion cheaper than not building HSR. Thanks again for proving my point!
