Comment Re:No Threat To Thunderbolt (Score 1) 355

So, I'm having trouble understanding this. The OS has a buffer somewhere in memory, and the the host controller has full R/W acess to the entire memory space so that it can try and write into that little buffer? Never mind the security implications, what about reliability? It seems nice and easy to take a system down through some really simple address arithmetic bugs. I really can't see the advantage they were trying for.

Comment Re:Memories do decay (Score 1) 426

Not strictly true.

Sometimes a particular item can be degraded by the the storage of another item. For example, artificial neural networks store trained stimuli in the weights between nodes. This storage is global in the sense that storing a new pattern causes a shift in all weights and so alters every other stored item slightly. No idea how it works in the human brain, but it seems completely plausible that storing a memory changes all of the others slightly up until saturation at which point they all get erased.

The idea that (in the article) that human memory should be lossless is bizarre and has no basis in any neuroscience whatsoever.

Comment Re:More or less than bitcoin? (Score 1) 88

There is a little under $6B of bitcoin in circulation, and it has a much wider range of uses. The thing to bare in mind about this story is:

Economist who studies Eve says it is very important and interesting to have economists studying Eve. Srly?

The article contains little or no value (cough, bit like the Eve economy then, cough) and the only vaguely interesting point that he makes is glossed over. Apparent ISK is not a fiat currency because CCP closely control the supply by tying it directly to... *stuff*. Remarkable.

That's interesting, thinking of scenarios where there is no adversary (other than "dumb luck") would a usage pattern like the following degrade the life of the drive:

Random access to live data: e.g. using the drive as a cache or hosting a database on it that contains live data. (in both cases assuming the size of the cache/database was filling the drive).

Or, to put it another way: what is the probability that a (uniformly?) random-access pattern on a drive-filling file would trigger the worst-case behaviour?

Efficiency is the ratio of useful output to wasted effort. Are you really in a position to evaluate what kind of society that would produce and how their global output would compare to our current system?

It may sound expensive in comparison to our current education system, but expense is a different issue to efficiency. What kind of society would result from every individual being raised to their own personal maximum potential. I suspect that the productivity of such a society would be higher than our own, and surprised that you feel capable of calculating the trade-off that implies between allocation of resources into education and increased productivity across the board.
