Comment Re:Anyone who knows refrigeration? (Score 3, Informative) 95

Because ammonia works. It handles wide temperature swings. It is very efficient weight wise. The tech is well known. The instrumentation is well known. The only downside is that it's impressively corrosive. That said, the Russians don't use it.

Which, in the end, is likely why we do.

Comment Re:Neuronal Tumors (Score 4, Informative) 110

The article lies. It says, "[t]he reason the viruses are activated specifically in the brain is probably due to the fact that tumours cannot form in nerve cells, unlike in other tissues."

Leaving aside the awkward phrasing ("form _in_ nerve cells" [emphasis added]), it turns out that 1% of brain tumors are neuronal tumors. "Tumors of the central nervous system that contain abnormal neuronal elements, termed neuronal tumors, make up approximately 1% of all brain tumors." (http://pubs.rsna.org/doi/pdf/10.1148/radiographics.22.5.g02se051177)

That said, I think I understand the gist of the argument. But I didn't know that neuronal tumors were so rare (or supposedly impossible, according to TFA) and felt compelled to fact check that assertion.

I think it may refer to the fact that neural derived tumors typically form from the neural support cells (glial cells, astrocytes) rather than the axons and dentrite of a 'nerve cell'. Lousy phrasing and really a stretch as far as significance.

Which segues into nicely hyperbolic title in TFA. What the research shows is that retroviral-derived sequences have some interesting control factors that are different from other cells. To intimate that this has anything to do with intelligence or even brain function is rather a stretch. It's a shame because the findings (a novel control pathway in the brain) is interesting all by itself.

Sigh.

Comment Re:Just hire a CPA (Score 1) 450

I imagine all professional CPAs use some sort of professional CPA program. The value is in the overall issues that the program doesn't understand. Despite TT's underlying complexity and the fact that thousands of hours of research have gone into the program, it can't tell you the annoying little details of many of the forms - the exceptions, the gotchas.

I quit doing my own taxes several years ago after the IRS came back and asked for $65,000 in back taxes because of some presumed investments that one of my wife's Mutual Funds had screwed up. The accountant took about 15 minutes, found that I had put one number in the wrong place and that the Mutual Fund AND the IRS had put a bunch of numbers in the wrong place - I ended up with a thousand dollar refund.

My taxes are moderately complex - a couple with W2's, 1099's, Schedule C's and some investment income. The entire tax code is batshit insane (like the rest of the country) but I can't do anything about that. I don't pretend I'm a lawyer, an accountant or a pilot. I'll mess with a lot of things, but not my money or my life.

Comment Re:AI acting against its programming? (Score 2) 258

Either the the one who said that is not very familiar with AI programming, or he/she means the vulnerability of an AI controlled system to remote code injections.

You can't just say we need to protect mankind from machines. What precise values do you want to force upon advanced AI controlled agents? Fail-safe circuit against murder, torture, censorship, discrimination or massive logic fault cascades?

A good start would be a promise not to create AI politicians. That should cover a whole bunch of evils.
