You have a strange definition of efficiency. In my universe it's [money used on medical stuff by medicaid]/[money given to medicaid]. Doesn't matter if there is any relationship between the person giving and the person recieving. Or charities would be awfully close to 0%.

And, um, if you want 'huge overhead'...please actually look at the money you donate to a church. Even the most honest and ethical church gives less to actually help people than, oh, Medicaid.

Snopes’ review lists several charities whose efficiency ratings are between 80%-90%.

And medicaid seems to be around 94-96%.

Comment Only 2T ? (Score 5, Insightful) 98

I wonder how smart it is to design a spec now with the upper boundary in size equivalent to a normal hard drive. Why stop at 32bits addressing when 48 probably doesn't make much of a difference (the 16 extra will be all zero for a while after all, close to no cost on the card and negligible on the controller) and would match (s)ata that way with its far more future-proof 128PB limit.

Flash cards seem to move as fast as HDDs, they only started later.

You missed that one Watt Balance.

The lump of platinum is precise at around 5e-8, the watt balance has reached 3.6e-8 at that point, but they expect to do better than that. The Nist, while holding the record right now, does not seem to have chosen the best path to reach better precisions than that. 1e-9 is expected (hoped? ;-) in some of the french experiments in a handful of years.

The Reason you use gas is it's easier to turn on and off the Coal/Nuclear.

Gas is only marginally easier than coal - it's the preheat time for the water in the loop that's the real killer AIUI.

Gas turbines (no water) are fast to start and stop, and they're very good when you need power *now*. They're used in France a lot for peaks. Civilian nuclear takes 2-3 days to change power levels significantly. I suspect that, compared to submarines, size matters.

There are so many things that can trip you up and give a completely wrong answer - and unlike programming (where your program doesn't compile or run correctly) you have no automatic way of discovering mistakes.

Errr, you probably don't realize it, but that sentence proves you're not qualified to talk about programming. Defining and verifying "run correctly" can be as hard as validating experimental results, simply because a run of a program is an experiment.

One interesting thing is that some of the most successful physical theories, successful in an "experimental validation" sense of the word, are pretty much out there where it comes to how things are really happening. Quantum electrodynamics are an impressive case. If you have the time, read "QED: The Strange Theory of Light and Matter", by R. Feynman. Not only it's very interesting and well written, it's also pretty illuminating on that subject. A good quarter of the book is about driving home the point that it is a mathematical theory that works impressively well but at the same time makes no intuitive sense, some like Einstein would say no sense at all ("God does not play dice" is the common paraphrase), where it comes to understanding the world.

His point three is not about whether the current concentrations of CO2 are human-produced (as you say, the isotopic ratios seem conclusive), but how much of the measured warming is due to CO2 concentrations. "We can't think of anything else" is not very good as an answer and, according to him (I have no idea), predictive models of temperature-vs-CO2 concentration seem to be lacking.

The state-of-the-art is crap, but it's still the state-of-the-art. In any case, that's what is currently best, for a value of best meaning "gets the best score in most MT evaluations when used competently". Moses is a bunch of code implementing fun statistical algorithms though, not a full translation system. The quality of the system you get depends on the quality of the training you do, and pretty much how you setup the system together. The guy was asking for the algorithms though :-)

Comment Re:I'd like to see this happen in Eve Online (Score 1) 134

IMHO, Eve Online is much more commerce oriented than Second Life. The makers, CCP, support a pseudo mechanism for real to virtual currency excahnge. A player can use real money to buy a game card, then sell the game code to another player for virutal money. So, there is market established exchange rate.

But that only goes from real to virtual. There is no CCP-supported mechanism for virtual to real conversion afaict, which would change things, starting with this little thing called taxes.
