Comment Vehicle platoons (Score 1) 262

If cars were on electronic adaptive cruise control and set to keep only a few feet between cars, and cars were organized into platoons based on the length of the typical green light, everything would move faster and smoother.

Traffic tangles are chaotic systems with properties like a gas. Fast movers just increase the temperatures all around. Platoons are like polymers and step down the chaos.

Comment Home remedies vs quack remedies (Score 1) 517

Cinnamon oil, mustard poultice, licorice root tea, green tea, honey, cumin, are all useful home remedies with medical effects well beyond the placebo effect. Just because they cannot be patented by Big Pharma does not mean they are ineffective. At issue here is the tens of millions of dollars it takes to run a full set of placebo-based double-blind studies. There is no profit in running these studies for home remedies.

There is a competition between "ethical" pharmaceutical companies that require a doctor's prescription for there products and the OTC suppliers like Life Extension, who have extensive research on animal models and metabolic pathways. If a Pharma company takes over an OTC formula the price goes up by a factor of ten. Lots of prescriptions could be safely delivered OTC at great savings to the consumer.

I don't support homeopathic remedies.

Comment It's a science show, not a religion show. (Score 1) 667

Keep the religious ideology on the religious channels. There are plenty of them. Creationists like to pretend that their religious ideas are science, but they are totally devoid of scientific evidence, by their very faith-based nature. Teaching Creationism as an alternative scientific doctrine is just another way to destroy young minds.

Every Creationist should read, as a penance, at least two textbooks on molecular genetics.

Comment Triconex SIS (Score 1) 245

I'm the original VP R&D of Triconex and developer of the triplicated fault-tolerant industrial control system.

These systems have NO single points of failure, not even the power supplies, and each independent CPU is "educated" from the other verified good boards. There is no commercial operating system in these computers. They run a combination of Relay Ladder Logic and Analog Control System usually downloaded from a Wonderware or XCell application in a PC and run-tested on the actual plant machinery..

The vulnerability would be in the PC end, if those PC's are running unprotected interfaces to the Web. The PC control systems must not be connected to the Web, and the actual control application in the control computers should be programmed with automatic safety shutoffs and overrides which do not depend on the PC connections. The applications I oversaw were set up that way.

Comment Re: I went back to corporate America because Obama (Score 1) 578

"Minimums are needed because cross subsidisation is rather integral to having affordable healthcare for everyone. Meaning those who are in the stage of their life that don't need much medical care pay more, but those that do are able to afford it."

In other words, you believe in redistribution of wealth. Maybe you don't understand that insurance is supposed to pool risks, not redistribute premiums.

Comment Re:I went back to corporate America because Obamac (Score 1) 578

Yep. definitley a troll.

I was part of a team of people that suggested HC plans that did not require turning insurers into Federally controlled utility companies. Some of the features we worked out were interstate portability, a homologated minimal support plan, FDA reform, medical liability reform that made sense and included BIg Pharma, and a new specialty of medical advisers who could navigate the treatment options in complex cases.

What did we get?

If you are in the middle class and you buy a new policy you will be paying more for the premium, even after reimbursements. Probably much more. However, with annual deductibles in the range of $3000 to $6500, all you really have is major medical insurance. It will be a genetically unlucky few who mange to collect anything over the deductible.

Comment Block chain was not hacked (Score 1) 704

From my reading of the article, the Bitcoin block chain was not affected. The vault is a list of account holders, their Bitcoin keys and names and their bit coin balances. The block chain is not touched until a transfer in or out of an account was made. It was the bank that was broken, not Bitcoin itself.

Yes, a better crypto currency would have a distributed banking system on a peer to peer basis instead of centralized banking like Bitcoin. It is coming (see Coinbase.com). Until then, keep your Bitcoin keys on paper in a a safe at home.

Comment Evolution is misunderstood (Score 1) 593

I'm writing an S.F. novel, "The Sage of Saggitarius" ,that features an enhanced woman, Zila, searching for the "secret of life" with the aid and funding of a very unhuman sentient over a thousand years old.

I've done years or research on evolution. The modern basis is molecular biology, not fossils, and the key constructs are the conserved genes that are 100 million years old. Evolution turns out not to be "survival of the fittest" because no one can define fitness with all the implication of the relationships among the environment, competitors, predators and their feedback loops. These are impenetrable webs of non-linear equations. Fitness landscapes probably exist, but most of the hill climbing leads to dead ends. And what happens when a particular species, such as humans, is no longer dependent on a particular fitness niche?

The work of Jeffrey England may be the great breakthrough. He sees evolution as part and parcel of of entropy. It cannot be observed by examining instances. It's an emergent phenomenon, like entropy itself. Life serves the Tree of Life. Evolution serves entropy.

These are not easy things to explain, and perhaps harder to understand.

Comment Re:even a broken clock... (Score 1) 523

Unlike the "parties" who need a fascist lockstep mentality to keep their supporters in line, there is no singular "Tea Party" nor any single tea Party leader. Not even Sara Palin.

It's hard for a fascist to understand, but we are principled individuals acting on our personal convictions, and we don't always agree. You can't characterize us as a collective. The fact that you try shows you can't think outside your own collective box.
