Comment Re:Not bad, looks like a clean record to me. (Score 2) 97

Too bad almost none of the commentators understand common facts about sports physiology and pharmacology. For example, the CORTICOsteroids given the tennis players for injuries would tend to make them weaker, not stronger (it is the ANDROGEN type steroids that are used by dopers), And it's dubious that Ritalin would help a gymnast, though it might an endurance athlete.

Comment Not bad, looks like a clean record to me. (Score 0) 97

Looking at the details, it looks like the positives in the US database were related to treament of injuries plus one gymnast with an ADHD diagnosis. Whereas, as far as we can tell, the Russian athletes were being dosed with more conventional doping agents that have no general use in Russia for non-athletes, and were forbidden to be tested for exactly that reason.

So I see the hack results as so far posted as a vindication for the US Olympic teams. Either they were remarkably clean or they were unusually good at hiding any doping that actually went on. Upright living (and avoiding doing vandalism if you are a swimmer) can be an excellent defense against scandal.

Submission + - Neuroscience would Fail to Make Sense of a 1970's Era Microprocessor, Says Paper (biorxiv.org)

wherrera writes: According to a preprint entitled "Could a neuroscientist understand a microprocessor?" on the biology preprint archive bioRxiv.org, using the same techniques as used in with latest probes used to inspect the function of the mammalian brain and its connectome fail spectacularly when used to probe a running simulation of the MOS6502 processor used in playing the classic Atari era video games Donkey Kong, Space Invaders, and Pitfall.

The investigators used probability analysis of correlation in signals as well as such techniques as "lesion studies" which used the destruction of a simulated transistor to imitate the process used by researchers investigating the effects of a lesion on the nervous system. They conclude that reverse engineering the brain is likely not to succeed until we have a better understanding of what the brain as a system is doing, since "we do not generally know how the output relates to the inputs" in the brain to even begin to properly guide such investigations.

Why not use google and a calculator yourself? Anyway,

see here for counts: http://www.cattlerange.com/cat...

Biggest cow states: Texas and Nebraska.

Cattle in Texas plus cattle in Nebraska: 11,700,000 + 6,250,000 = 17,950,000
Methane output per year per cow per Google: about 95 kg per year, or 8 kg per month

Therefore, Texas plus Nebraska cattle make about 143,600,000 kg = 143,000 metric tons of methane per month. And there are a lot more cattle in other Western states.

The spill was of 98,000 tons, or 98,000,000 kg. ...you are welcome :)

Comment Same as the ITunes DRM cat-and-mouse game (Score 1) 405

Remember back in the Jobs days when Apple sold music with digital rights (mis)management? Back then, they would re-update iTunes to re-encrypt every time the music player's encryption dll was (re)cracked.

So now it's a new decade, but same old same old cat-and-mouse game, except that:

This time it's Apple doing the cat and mouse game with its own people :).

Comment Re:I have a bridge to sell you, says Mr. Oliphant (Score 2) 138

That those prehistoric people were probably at least as intelligent as the average slashdotter, and they likely spent decades testing, reviewing, debating, and verbally sharing various hunting skills. It's likely that they had many ways of crippling or killing large game other than the ones we can see by marks left on old bones.
