No. The VM does not have the key. The hardware has the key and only that core can run it. Practically, someone can take the die apart, xray it, and get the key. At that point they have access to the code that was was on that cpu -- maybe -- but you can avoid total loss by distributing across a large number of cores. The intel implementation was broken, but the idea is pretty sound. Seriously, read the papers.

Comment Re:The Great Ethanol Scam (Score 1) 556

The most likely case is that the EFI system does not have enough control authority to trim the mixtures for fuels that have very different stoichiometric ratios. For example, E85 may require up to 30% more fuel volume than gasoline. That means you need fuel injector with 30% additional capacity _and_ EFI logic to drive them. It's not very hard to do, it just hurts the bottom line.

The information in that article skirts the border of misleading and bogus. Almost any modern (EFI) gasoline engine is capable of running an alcohol fuel with minimal modifications. Many engines, such as low displacement supercharged ones used in small cars, _will_ run more efficiently because of the higher octane rating. Ethanol is a very effective cleaning product. Many people seems to believe it can "gum" up engine parts while in reality it is simply stripping precipatates off the fueling system itself that may have built up over years of use.

The 10 Most Absurd Scientific Papers 127

Lanxon writes "It's true: 'Effects of cocaine on honeybee dance behavior,' 'Fellatio by fruit bats prolongs copulation time,' and 'Are full or empty beer bottles sturdier and does their fracture-threshold suffice to break the human skull?' are all genuine scientific research papers, and all were genuinely published in journals or similar publications. Wired's presentation of a collection of the most bizarrely-named research papers contains seven other gems, including one about naval fluff and another published in The Journal of Sex Research."
