My phone battery has a capacity of 2.1Ah. To charge it in 20 seconds would require a current of 380 Amps. What kind of charger could safely supply that?

it provides the contradiction by constructing a list of numbers at least one of which must be a new prime. It's simple to test each of them. If you want to construct an infinite list of primes, just repeat indefinitely.

I'm pointing out that the existing proof is constructive, not giving another proof.

N!+1 either is prime or has prime factors not in 1...N. Try factorizing the integers N+1 ... N!+1 in turn until you come to one that is prime.

What have you bought over the last year? How has their price varied in dollars and in bitcoins? No currency's value is constant, but some are a lot more constant than others.

Oh wait, it *is* a press release.

A program can't necessarily fail gracefully. An assertion failing means that something has already gone wrong; perhaps data structures are corrupted and continuing might result in worse damage: writing wrong data, deleting the wrong file. Returning to the caller is not necessarily safer than exiting.

It turns out that some programs (e.g. Unison, a usenet reader) will crash if they try to display a document containing the string. Quite possibly more will turn up - they'll be programs that try to recognise URLs and display them as a link.

However, in this case the only bug is in the assert() call itself. It didn't catch a mistake, it was one.

> I thought it was more if you win playing the same moves that a computer would make you are cheating.

As Regan points out, this is only unlikely if you play the same moves as a computer, and many of these are cases where the advantage of the chosen move was tiny. If the computer chooses moves that are forced or better by a clear margin, so will a good player. On the other hand, if the computer's preferred move is only better by an insignificant amount, it's very unlikely that a human will repeatedly do the same.

Of course, this allows cheats to improve their strategy: where there are several moves with little difference between them, choose randomly instead of choosing the best.

I have to type something here to please the filter.

... that the people with the most interest in putting malware on computers were the very same people who sold you software to remove it. So I don't find this in the least surprising.

I think "Scorpion Stare" and make sure I'm not in the line of sight of two of them.

So he left the US because he didn't want to pay taxes, and now finds that instead he has to bribe politicians. Life is so hard for the rich.
