Comment Re:Fact check or PC checking? (Score 4, Informative) 337

It's immigration (and emigration) whenever a group of people migrate from one region to another, regardless of what the reason is or how they're treated.

It's a little bit of a tricky word territory because it would be inaccurate to call them "immigrants". That word is usually used in modern English to refer to non-forced migration, so could make the reader draw inaccurate conclusions.

It is, though, completely reasonable to put the event under a discussion of "Patterns of Immigration", because that is clearly referring to large-scale movements of people with important sociological and historical impacts. Historically, many major human migrations have been the result of slavery, exile, genocide, and other such unpleasant and rather non-voluntary reasons. They're still called migrations.

Comment Re:Perhaps this explains my Garmin (Score 1) 131

According to this article (okay, okay, the summary), GPS error causes measured distances to be systematically overestimated.

What you're talking about -- a different but noticeable factor -- is that GPS polling frequency causes measured distances to be systematically underestimated. Because it's only sampling once every N seconds and then, because there's quite a bit of noise, applying a smoothing function to the result, it cuts the corners off of paths. It can cause pretty substantial underestimation, even when moving relatively slowly along gently curved paths.

Bullshit. Exposure to RF is inducing cancer because it randomly changes DNA. The dose does not matter in this effect.

Bullshit. Wavelength is not a dose.

Long-wavelength RF, below the ionization threshold, does not cause cancer because it lacks the energy necessary to "randomly change DNA". You're right, the dose doesn't matter -- sub-ionization RF doesn't cause cancer.

Comment Re:Amazon has gone for obfuscation as business mod (Score 1) 259

I order quite a bit from Amazon, including things that split shipments (ship different days or are a mix of Prime and non-Prime). The "Your order [...] has shipped!" e-mails list an amount charged for the items that actually shipped, and these are the same values that appear on my credit card. While the default "Your Orders" view on the website groups things by order (which is not the same as shipment or credit card charge), the "Invoice" link on each order breaks down the order correctly (by shipment, with separated charges). These also match up with credit card charges.

Comment Re:n=6? Seriously? (Score 4, Informative) 96

I know the Slashdot trope is that n is always too small in any study, regardless of the actual size of n.

The sample size you need to demonstrate statistical significance (or, conversely, the level of statistical significance achieved for a given sample size) depends on the behavior you're measuring. If you're measuring a small change in a rare occurrence, you need a very large sample population. If, on the other hand, your hypothesis is "black sheep exist" or "this vaccine reduces the mortality rate of a disease that has an untreated survival rate of 1 in 100,000", then a single occurrence (black sheep, surviving subject) is significant at n=1, and two occurrences out of even a tiny n is excellent.

Shade, local terrain, building codes, subsidies, power company buyback policies and rates. There are also a lot of odd business arrangements that are localized that can dramatically reduce the solar capital cost.

I have no idea if they account for any of these factors, but there are certainly a lot more factors than weather-adjusted annual insolation.

The US has officially been proven to be an oligarchy as described here

You know you're on the Internet when a single study counts as "official proof".

Now you just need someone to reply asking for confirmation, then a person to reply that it is confirmed, since they saw that the same study does in fact exist. (Needless to say, no involved parties have read the study.)

Yes. That is made clear. Almost all of the article is about the NSA's capabilities. Then, at the end, some text, including the quoted part, about how this is important even if you don't mind the actions of the NSA.

"Even if you're not inclined to view the NSA as an adversary ... America is hardly the only intelligence agency capable of subverting the global communications network. ... While it's cheap to hold China out as some sort of boogeyman, it's significant that someday a large portion of the world's traffic will flow through networks controlled by governments that are, at least to some extent, hostile to the core values of Western democracies."
