The author of TFA didn't write "perfectly accurate" but "land mass size on a relative scale". Bud is correct.

You can perfectly "host your own email server" while sending outgoing mail through a smart host. No falsely-tagged-spam issue that way.

Decidedly, statistics is hard. Everything above is wrong. Let's label the twenty drives D0 through D19. There are 2^20 possible scenarios, which can be represented as a string of 20 bits: • 00000000000000000000 = all 20 drives are work

by mrb 8y ago
Yes, but this was the OP's scenario: what happens when 3% of drives all fail at the same time when the DC is powered back on. Edit: actually the math is still wrong. The chance any 4 out of 20 drive is failing is: .03^4 × C(20,4) = .03
942.
by mrb 8y ago
Oh you are right. The OP still has a slight error though. C(20,4) = 4845 possible combinations of failing drives (4 out of 20.) Therefore the chance a file is irrecoverable is: .97^16 × .03^4 × 4845 = 0.241% (not 0.3%) But the OP's con

You are right that Summit is overbuilt if it was going to be used just for raw crypto mining hashpower. However, even so, it would be quite profitable... The last double spend attack on BTG stole ~$20M. There is no reason to think it couldn

The trend of power consumption is no different between GPUs and ASICs. Either way, miners will always be competing to add more and more capacity.
