Comment By this logic (Score 5, Interesting) 238

shouldn't we also have usage-based pricing for the TV they sell us? So that we pay "fairly" for for the fixed cost of establishing the network? Why would that model be different, since it's not really about congestion, as admitted in the article?

The electric bill and buffet examples in the article are terrible: when we pay for electric usage, we actually are paying for utlization/generation; use more and something (coal, natural gas, etc.) actually gets consumed more. And most buffets are all-you-can-eat; if you're paying by weight or something, the analogy is the same — you're actually consuming something. But both bandwidth and TV channels are there no matter how much they're "consumed." Bandwidth can be saturated (the congestion problem) but it can't be actually consumed.

If we're going to talk about "fairness", let's talk about:

  1. 1. Fair access to the wired networks built out, frequently, under monopoly guarantees
  2. 2. Fair levels of monetization of the network: does the telecom industry really want the equivalent of a utilities commission deciding how much they profit?

But the objection still holds: you haven't told us what consciousness is, just that it's not "something else." Fine. What about the human cognitive processes working produces whatever-it-is that we experience as introspection, and why do we experience it the way we do?

Until someone can answer that question, functionalism has written a check it can't cash. Assigning consciousness to some not-yet-understood aspect of cognitive processes is in no important respect different than simply declaring consciousness "mysterious."

There's no explanation on offer for how processes such as the ones we're currently able to describe produce phenomena like consciousness -- so either there's a "something else," or there's "something else" about the processes that we don't yet know.

You can take your mystery in whatever box you like, but the point is that consciousness is not yet anywhere near being well-understood, even in principle.

The consciousness "debate" will never be settled (at rather, widely agreed upon), because the answer just doesn't mesh intuitively with human introspection.

And, put non-technically, that's kind of a problem for functionalism.

We need either (a) an explanation of how some activity describable in functionalist terms can account for the experience of introspection or (b) an explanation of why introspection is unimportant to the relevant definition of consciousness.

Since case (b) seems unlikely, and case (a) is a blank check drawn on an unknown account, the pronouncements of experts giving us a timeframe seem fairly unreliable.

And this opens up an interesting possibility to provide an incentive to properly mark packets for QoS (on the user's end).

If Comcast added to this the following wrinkle: packets marked for "bulk" QoS automatically get assigned to the BE traffic level, but do not count against the consumption metric used to prioritize the rest of your traffic.

Presto: anyone who both torrents and watches streamed video now has an incentive to use a torrent app that marks its traffic as bulk.

Additionally, maybe streaming providers start getting sophisticated about how they deliver their streamed video to try to make part of that bulk as well, or at least do so adaptively when congestion is low. And downloads to iTunes, etc., easily go bulk.

"Miraculous" Stem Cell Progress Reported In China 429

destinyland writes "In China's Guangdong Province there's been 'almost miraculous' progress in actually using stem cells to treat diseases such as brain injury, cerebral palsy, ataxia and other optic nerve damage, lower limb ischemia, autism, spinal muscular atrophy, and multiple sclerosis. One Chinese biotech company, Beike, is now building a 21,500 square foot stem cell storage facility and hiring professors from American universities such as Stanford. Two California families even flew their children to China for a cerebral palsy treatment that isn't available in the US. The founder of Beike is so enthusiastic, he says his company is exploring the concept of using stem cells to extend longevity beyond 120 years."

Comment 40-minute reset timer? (Score 1) 560

From TFA:

Because we didn't know why this problem kept appearing at 40 minutes, we decided to set a timer. After 40 minutes, we would stop the car and reboot the computer to restore the performance.
So they knew that around 40 minutes, the performance would *gradually* degrade, and they fixed it with a timer that rebooted their system.

People! Of course it's a memory issue -- not a leak, as everybody else has explained, but of course the issue is that your system got memory-poor. Of course. Nobody every checked the Windows task manager to say "Gosh, no more memory. Maybe that hurts us?" You don't need a profiler to figure out what this problem was; it probably helped to figure out where the problem was.

The bigger question is, who sets a reset timer and considers their problem fixed, and, even if you don't have the timeline to find and fix the problem, who times the reset to the magic number of 40 minutes and not to the degrading performance?

The truly amazing thing is that people bright enough to build the rest of this system could be so remarkably clueless about basic debugging.

Microbes Churn Out Hydrogen at Record Rate 168

FiReaNGeL writes to mention that Penn State Researchers have improved on their original microbial electrolysis cell design bringing the resulting system up to better than 80 percent efficiency when considering all energy inputs and outputs. "By tweaking their design, improving conditions for the bacteria, and adding a small jolt of electricity, they increased the hydrogen yield to a new record for this type of system. 'We achieved the highest hydrogen yields ever obtained with this approach from different sources of organic matter, such as yields of 91 percent using vinegar (acetic acid) and 68 percent using cellulose,' said Logan. In certain configurations, nearly all of the hydrogen contained in the molecules of source material converted to usable hydrogen gas, an efficiency that could eventually open the door to bacterial hydrogen production on a larger scale."
