Comment Re:Is this additional income tax? (Score 1) 481

My wild-ass-guess is that everything we buy costs at least double due to taxes all along the way that accumulate.

That would be true with a straight revenue tax but almost nobody does that. Let's say you charge a 20% tax rate. That's not 20% of the ore that's 20% of profit on the ore. So if your margin is 5% on mineral extraction your effective tax on the ore is actually 1%. Add up say 20 steps and that's only 20% not 50%. That's where your logic fails. The next place to do a quick sniff test on your assumption is total taxes / GDP. Thankfully someone has already done that.

It's around 25% of GDP. So about 33% of the price of goods and services is tax. But that's the maximum not the minimum. A lot states like mine charge a 10% sales tax. So you can't double count that tax. It would be 15% of GDP or about 17% more expensive.

I am comparing it to Manhattan because that's the rate of sprawl [Seattle has] been experiencing

LOL Wut!? Ok, sure, compared to Manhattan Seattle is a "ghost town". But so is every other city in North America. You're expecting foot traffic in Seattle to be similar to Manhattan because "it's the same rate of sprawl". That's the dumbest fucking metric I've ever heard. So a small town of 50 people which quadruples to 200 people should see Manhattan foot traffic rates because their rate-of-sprawl metric is similar?

There is one statistic that affects foot traffic, it's called density. Manhattan has a population density of 70,517/sq mile. Belltown is the *most dense* Seattle neighborhood and it has 13,516/sq mile. Seattle as a whole is around 7,000/sq mile or 1/10th of Manhattan's density.

One might well say that she can do all this and just not get the diploma if it's so important to her.

Anyone saying that would be a capital A asshole. A straight-A student has earned her graduation certificate. That her future plans didn't align with those encouraged by the state isn't relevant.

Yes there are always exceptions

I'm not talking exceptions at all. Only average generalities.

And I stick with my age 10, for the majority of kids that is when they should have the skills, knowledge and thinking skills to get the most benefit from CS.

You have a particular notion of what skills and benefits are associated with CS, and I fully agree that your set of skills and benefits will work best around age 10 (maybe later).

I have a different notion of what skills and benefits are associated with computing in school. I think it keys off a set of skills that are much more fundamental and early skills than the ones you do. I think its benefits are more broad-ranging than you do. That's why I think an earlier age is appropriate.

So, the age I was talking about is close to being the same as yours. you said 9, I said 10, neither age is preschool

True, but you justified your claim of 10 year minimum by listing the skills that people acquire around 10 years of age:

language, mathematics, 3d space, geometry, numbers, size , abstract ideas and hopefully the start of critical thinking

I justified the usefulness of teaching computing to younger kids with an entirely different skillset, skills which are developed since toddlerhood. My only personal experience datapoint was of teaching computer science to 9 year olds (which is why I gave the example) but now that my oldest child is 3 I'm already seeing her have a bunch of these skills:

algorithmic thinking, control, power, data not a mystery

Uh, no one's done 3D facial scanning for authentication

Are you sure about that?

Windows Hello-supported devices use two cameras to create a 3D image of your face.

One of the cool new features announced for the upcoming WIndows* 10 is Windows* Hello [...] The recognition is done using two type of camera in cooperation; the first is a classical HD camera and the second is a depth camera (infrared) for 3D an temperature scanning.

http://www.pcworld.com/article/2937701/why-most-of-us-will-miss-out-on-windows-hello-windows-10s-facial-recognition-feature.html
But the technology depends on “depth cameras,” which use infrared light to peer through makeup and beards to identify users. It’s these cameras, primarily made by Intel, that analysts and some PC makers believe will be too expensive to build into the sort of cheap PCs (with cheap webcams) that consumers prefer.

http://www.dell.com/support/article/us/en/19/SLN298266/windows-10-hello-facial-recognition-feature---supported-systems-and-requirements?lang=EN
The Windows 10 Hello Facial Recognition feature requires an Intel RealSense or 3D Camera to support facial unlock features. This is not available on all Windows 10 tested systems and the current list is detailed below.

It's true that one page in the Microsoft docs say that they use IR to account for differences in ambient lighting, and make no mention of the presence of absence of 3d scanning:
https://docs.microsoft.com/en-...
But then other docs give the impression that Windows provides two API frameworks, "Companion Device Framework" and "biometric":
https://docs.microsoft.com/en-...

So maybe it's just down to the device driver whether it uses 2d or 3d scanning to power Windows Hello, as suggested in this article:
