Comment Re:Intensely idiotic (Score 4, Interesting) 127

Is this a trick question? How is "fair use" not applicable?
This is absolutely no different from the "scanning" and "putting up" that google does of every other part of the internet. Why should the fact that it started out in a grossly inefficient medium be any distinction whatsoever?

Comment Re:Correlation != causation. (Score 3, Insightful) 223

The correlations are NOT "false". The relationships between the numbers are (almost always) NOT "conterfeit".

"Correlation does not imply causation" means exactly that. If the sky is dark and people are carrying around umbrellas, this does NOT imply that darkness causes umbrellas, or that umbrellas cause darkness. The causal relationship between two numbers is not determined by how often one number changes at the same time as another.

To put it another way: correlation is an *observed* behaviour, causation is a *tested* behaviour.

Comment Accountant Metaphor (Score 1) 383

It's always strange to me that business people understand the importance of keeping track of money, but not other company resources.
To put it in terms they understand, try explaining it in terms of accounting.

Imagine an accountant who only kept track of exactly one number: The amount of money the company currently had.
This accountant might be really good at remembering where all the money is, and can even explain where all of that money needs to go and where it came from, usually. But he only ever actually writes down the current amount.

Throughout the day he does everything on a single calculator, then at the end of the day he writes down the final number, to use as the starting point for the next day.

Sometimes, just before or just after a major transaction, he'll write down the number and maybe the date, first.

But it's only ever one number.

Would you hire that accountant? Would you trust them with your accounts? Even if the accountant seemed really good at staying on top of things?

You can't just keep track of "where you are." you need to know how you got there. You need to know why you took each step along the way.

Indeed. This is the one that people don't seem to understand.
As far as I am aware, no mathematical proof has ever been offered which declares cold fusion to be impossible. This is as opposed to, say, accelerating beyond the speed of light, which has been proven to require infinite energy.

Note that I don't mean to imply that this "cold fusion" is not a fraud, but crying "Thermodynamics!" at every alternative-fuel story makes me wonder how these people would have responded to the discovery of coal.

Comment bitcoin: broken by design (Score 1) 858

bitcoin is designed to have "diminishing returns" in terms of bitcoin generation. ie: the longer the project goes on, the fewer new bitcoins will be generated. This ignores that the longer the project goes on, especially if it is successful, the fewer bitcoins will usefully exist. ie: not just a counter that says how many bitcoins exist, but the number of bitcoins which are valid and usable, as opposed to being lost due to lost keys, etc.
