Assume server rack and contents are made of aluminum (what is the predominant material in a server rack?). Let's say the server rack is 2m in height, but it's not fair to make the whole thing metal. Let's say 20% of it is metal (aluminum for this calculation), the rest is air (or, for the sake of calculation, vacuum). Alumnium has a density of 2g / cm^3 (so a 1m x 1m x 0.4 m slab of alumnium would weigh 800 kg, which appears to be in the middling range for what a server rack can accomodate--again, keep in mind, this is a really rough calculation).
Okay, plugging in Aluminum into XCOM gives a total attenuation in the 100-1k MeV range of ~0.03 cm^2/g.
e^[-(0.03 cm^2/g) * (2g / cm^3) * 40 cm] = 0.09
In other words, that's 90% attenuation. Keep in mind that this was a ridiculously sloppy calculation, with my material assumptions (and possibly energetic ranges) being way off (also, neutron cross-sections could easily be different than photon cross-sections). The point is, it's certainly possible (nay, likely) that the material of the servers themselves are providing shielding from the servers on the bottom of the rack.
I know how to interpret my LDL and HDL levels. Most people understand what it means to be "positive" for HIV or Hepatitis. The last blood panel I had included a whole column of "acceptable" ranges. I think the idea here is either that your doctor orders the blood panel and gets you the results that day (rather than a week later) or that you take the test and then say, "Oop. Time to see the doctor." Or it's for chronic conditions (like high cholesterol) where self-monitoring is entirely possible.
It was your choice to sign up for a plan with a $6000 deductible, and I'd imagine it's quite a bit less expensive than your old plan. If not, pony up some details. We don't need your name and Social Security number to verify what you're paying for a plan under the new healthcare exchanges.
Keep in mind, the cost of the pharmaceutical company's study used to verify the accuracy of the test and gain FDA approval likely pushes the cost-per-test up quite a bit.
I'm sure it depends on the test, but my guess is pretty accurate. I was going to throw in some citations with some actual figures, but without specific tests / brand names, all I can tell you is that tests based on microfluidics are being billed as "fast and accurate."
Exponentially implies that the growth rate is proportional to the population size. So if the author's point is that every conversation he has leads to two more (matching my experience) then "exponentially" is used correctly.
It all depends on how you measure the "community." If you're talking about unique visitors to/., then I can pretty much guarantee that lurkers who never/rarely post are in the majority. Trolls, by their nature, tend to post more than other types of people on the interweb.
I feel that DVRs are vital to a healthy democracy. Being able to skip all political ads, I feel, has made me a more informed (or, rather, less misinformed) voter this year.
I don't know what airline YOU fly, but any flight attendant on any flight I've ever been on would make the passenger hang up, and if they refused, they'd call over the sky marshal.
Now you'll be able to read your kindle on the plane, but you still won't have to put up with the passenger next to you carrying on a loud phone conversation (save, maybe voip?).
I'm a firm believer in not getting any new console until you absolutely have to (read: until there's a game you really want to play that's only on that console). If good titles are scarce (::cough:: 3DS::cough::), it means you get to wait for the price drop / patching / additional features / new version.
GDP measures what we PRODUCE, but this article, as I read it, was talking about SALES taxes. So it's not relevant what we produce--it's relevant what we BUY. Did I misread?

Back-of-the-envelope calculation using XCOM.

Q: Why does a Mars rock taste better than an Earth rock?
A: Because it's a little meteor.
What I'm asking is why people are concerned about him being extradited to the US when, as far as anyone knows, the US doesn't want him.
I'm confused--isn't he hiding out because he's worried about getting extradited to Sweden to face rape charges?

Indeed, thank you.
Someone asked, here's the answer: a whole lot better than the labwork you get now. Example: HDL tests are allowed to have a 30% margin of error. Theranos' tests are accurate to within 10%.

There are far easier--and less obvious--ways of getting someone's DNA.

What, would we stop after finding just one sign of intelligent life?
Ah, thank you. Was wondering about that.
Luckily, the extinction mechanism is strong.

Can this Linux kernel run a Javascript VM? If so, can that VM run the Linux kernel? And if so, can that kernel run a Javascript VM? And if so...
Having the same problem. Based on the above comments, I think we all managed to slashdot it.

I shouldn't have to install IE if I want to set up a little virtual ecosystem.
