Comment What carriers want is not to be carriers (Score 4, Insightful) 126

They want to be closed worlds, revenue generating from everything you do on their network and with their business partners only.

They want perpetual customer lock-in, because each "carrier's" dog's breakfast of apps and locked-content portals would be so different from other carriers' offerings that it would be too confusing and too much work to ever change the "Carrier-net" (as opposed to Internet) that you belong to.

Comment This representation does not seem compact (Score 2) 68

I only glanced at the news article summary of the research, but it seems like they're saying you need an exponential number of neuron groups compared to the amount of information in bits that is coming in or being classified. It's hard to see how ONLY this organizing principle could be efficient in terms of amount of matter and energy needed to store the info.

There must be another organizing principles going along with this, to make it representationally and physically efficient.
Principles such as perhaps:
1) The cliques are organized in an efficient representation abstraction hierarchy
2) Only create neuron cliques for those combinations of things which DO occur, rather than the exponential number of possible combinations which do not occur in the world. i.e a sparse distributed representation, as has been suggested in other neuroscience and computational neuroscience research.

the challenge is to make truly decentralised versions of Internet communications technology popular and easy to use, therefore adopted widely. ...and to do this quickly, so decentral tech can be well established before governments try to make decentral and personally owned comms and encryption technology illegal.

Comment Energy storage and HVDC transmission (Score 5, Interesting) 275

"Wind and solar are viable, they just don't lessen the needed amount of fossil fuel capacity needed"

I call bullshit. We could put in HVDC transmission lines (Max distance around 3500km or 83% of the width of the contiguous United States) running from east to west and north to south. Those lines are each longer than a weather system is big, so you ship wind power from windy areas to calm areas that need power, and from sunny daylight areas to dark or cloudy areas that need power.

For the rest of the balancing needed, we could, for example, put in one gigantic hydrogen electrolysis and storage and fuel cell generator facility in the geographic center of the country. It would only be 30% round-trip efficient (energy out compared to energy in) however then you just need to install three times the wind and solar you would otherwise need, and Bob's your Uncle. If you don't want to do that, use a bunch of large compressed air storage facilities http://energystorage.org/advan... running at 70% round-trip energy efficient.

And if you still don't want to do very large storage for some reason, then tap into the enormous geothermal energy rersources under the US. Way more than enough energy for the country's needs there. No GHG emissions.

How about a combination of all these strategies. The technology is there. The price is becoming reasonable, and a small and not too punitive carbon tax would make it economical to build all this new infrastructure fast. We just need to get off our asses and do it.

You mean issues like that everything Trump touches is going to turn to shit?

He's the shit alchemist version of King Midas.

You're going to have healthcare for the rich, stupid-ass trade wars that are no-one's fault but your own and a sinking economy because you're opting out of the rest of the world, and a more messed up environment. Oh well at least the 1% will be laughing all the way to the bank with their new plunder, freed up from those pesky regulations and taxes, so it's not all bad.

He proposed a lot of good policy, but Republicans vetoed pretty much all of it. They were actively obstructionist, for the sake of messing with both him and everything he stood for. They've developed a truly evil strategy of sabotaging government, as their strategy of winning the next election. You can't blame the lack of progressive government action over his term on Obama. That would be very naive.

Comment Re: Stop breathing! (Score 1) 559

You have perhaps forgotten that virtually every proposed Obama policy and budget was rejected by Republican legislators and thus not implemented. There was one major exception, the ACA.
So the result of Obama's term cannot be judged as a being a result of being what he would have done had he had the power. He did not have the power. The few things he did have direct executive power over, like getting Bin Laden, and regulating CO2 pollution, he did implement and they had some positive impact.
Everything else was blocked by Republican linebackers. What a f*cking waste of opportunity.

It's really really hard, granted.

In my experience in the systems engineering industry, there was rarely any re-use of design or code from one project to the next similar project. Silo-ism and misaligned incentives.

Imagine if the reliability of this kind of EDL system and its software could be improved by evolution where different space agencies and subcontractors shared and re-used their ideas for improving solutions to the complex problem.

Imagine all the landers... living for today.
