Traffic Jams In Your Brain 250

An anonymous reader writes "Carl Zimmer's latest foray into neuroscience examines why the brain can get jammed up by a simple math problem: 'Its trillions of connections let it carry out all sorts of sophisticated computations in very little time. You can scan a crowded lobby and pick out a familiar face in a fraction of a second, a task that pushes even today's best computers to their limit. Yet multiplying 357 by 289, a task that demands a puny amount of processing, leaves most of us struggling.' Some scientists think mental tasks can get stuck in bottlenecks because everything has to go through a certain neural network they call 'the router.'"

I beg to differ. btrfs is mainly oracle driven. Most of the development is by oracle payed engineers - and oracle bought sun with zfs already mature and in place - what's their incentive to continue pouring money to compete with their own product?

FUSE is bad on so many levels - basically it doesn't work, crashes repeatedly and generally unsuited as hell for an FS that wasn't created for it. tried several instances of zfs FUSE over the years - never got it to work anywhere near as well as on native solaris. That said, there are other alternatives openindiana is based on the opensolaris codebase, created by whatever remains of the community after oracle killed(? in some press releases oracle tech strategists claimed opensolaris is transformed to a new solaris express...) the project. and slashdot already reported on native zfs for linux - http://linux.slashdot.org/story/10/08/27/2259253/Native-ZFS-Is-Coming-To-Linux-Next-Month

Investors walk away because investors walk away. Investors walked away on almost all major artists of the 20th cent. If it's not the perception of piracy, it'd be the perception of poor sales figures, or the perception of public backlash, or the perception of of being under/over perceptive. Investors in the art industry mostly suck at recognizing new talent. Old (as in provably profitable) talent they have no problem with. Go figure.

get a notebook (not net , note) with the new intel core i7 640M (U or L - http://ark.intel.com/Compare.aspx?ids=43563,47700,). The U model at 18W TDP gives the atom chips a run for their money (well, not really in same category, but much better performance/wattage than anything before mobile nehalem came along). Lenovo has the x201s, but I'd take a look at the fujitsu P770 series - http://store.shopfujitsu.com/fpc/Ecommerce/buildseriesbean.do?series=P770. Not really in the netbooks price range, and not featuring ION (which is a true shame) but more than adequate from power consumption versus performance standpoint. If you want a portable gaming platform, either alienware or one of the eurocom models ( http://www.eurocom.com/ ) might suit you better.

Comment Re:Article missing a critical detail. (Score 1) 687

I actually read TFA, and it states, as the summary quotes, "Apparently, the student violated school policies", but the article doesn't state the policy in question. It is hard to know if this is a case of stupid overreaction or a real violation of the rules. Does anyone know the exact wording of this "policy"?
