Comment: 20% to 40% ??? No. Just no. (Score 1) 331

To avoid the 20% to 40% power loss when converting from DC to AC

...they're doing it wrong. DC to AC conversion is easily achieved in the high 90% range. For instance, a typical solar inverter is around 95% efficient. And you can do better, it just gets more expensive (although that's a one-time cost, whereas energy loss is a constant concern.)

Someone is pushing some other agenda here.

Sure. Did it to myself decades ago. Offspring of my genetic line aren't of the least bit of interest to me; perfectly happy raising kids of other birth who needed parents (5 so far, mostly excellent results.) Plus that whole "all the bareback sex with my SO we want, any time" thing is awesome.

Which, again, is just how I approach feline guardianship. Don't need new kittens from them. Plenty of kittens out there that need to own their own human.

Funny that, your point 2 is in direct contradiction to point 1a. You are effectively stating that your needs as the vendor are more important than the needs of the customer organisation.

Apparently you're a good example of "there's money to be made prolonging the problem".

Dolby does a lot of good research. That you throw them aside as a relic of the past, while at the same time discrediting them for some of the formats you praise (AAC is a thing in part due in part to Dolby's participation in creating the standard) simply shows that you have a myopic and illogical view of the world.

We are a representative democracy, and also a republic, and those are not the same thing.

The US is both a democracy and a republic.
The UK is a democracy but not a republic.
North Korea is not a democracy but is a republic.
Saudi Arabia is neither a democracy nor a republic.

Being a democracy or not is about how and by whom the power of the state is exercised. Being a republic or not is about in whose name the power of the state is exercised.

A republic is a state that officially belongs to the people, in whose name its power is exercised. The degree to which the people themselves direct the use of that power can vary from complete (in a direct democracy) to partial (in a representative democracy) to none at all (in an autocracy).

A democracy is a state that is directed and controlled (to at least some extent) by the people, whether the power of that state is in their name (as in a republic) or not (as in a monarchy).

The US is a republic, because the power of the state is officially that of the people (which is why court cases are titled things like "The People vs ..."). But the US is also a democracy, because that power is exercised, indirectly through representatives, by the people themselves, and not held by an autocrat who wields it in their name and ostensibly for their good but without any input from them.

I think it's a little too easy to say that the problem is "we're being too easy on children". And yes, I think that there's a sort of Mrs. Lovejoy "Won't someone think of THE CHILDREN" every-child-is-a-perfect-snowflake political correctness that is a problem. However, I also think it is important to be accommodating to the different needs of different children.

There's a larger problem, which is that we don't know what we're doing, and we don't even know what we're trying to do with education. Are we providing vocational training to get a job? Are we advocating a general liberal-arts-type education? Are liberal arts stupid and useless? I can't seem to find a consensus.

So instead, we speak broadly about accountability without specifying what people are accountable for producing. We make our kids take a crazy number of silly standardized tests, and put a lot of pressure on them (and on teachers) to perform well. It's not clear that the standardized tests are testing anything that we care about, especially since it's not clear what we care about. We're telling kids, though, that it's vital that they do extremely well on such tests, or else they're stupid useless people who are unfit to do anything but become a janitor, and "being a janitor" is described as a punishment.

It's not at all clear to me what we think we're doing, but what we're doing is awfully stupid.

I know you just want to dig at creationists, but keep in mind - since "scientific consensus" is considered an alternative to hard evidence, the problem is just as bad on the other end of the spectrum.

Worse, really - at least creationists don't pretend to have scientific backing when they're making shit up.

Add the error and difficulty of subtracting rider movement (remember, a phone's accelerometer is not something that is fixed to the chassis of the vehicle, but instead is something loosely carried by a squishy human being) and I'm going to say the answer is probably far closer to 0% than it is 92%.
