Read much more coherent coverage from IEEE Spectrum.

Spectrum is great - important and well-written technological articles that 1) get their units correct and 2) don't get breathlessly hyped up like a press release. For a while, the print magazine was the main reason I kept my IEEE membership current. Now the whole thing is posted for free online.

Shade, dark weater, and high lattitude shifts it downward. (Forget about solar in Seattle, for instance.)

Someone ought to tell that to Germany, which has a mean latitude of 51 and plenty of cloudy days, and generates a significant fraction of their power from photovoltaics.

Naw, who am I kidding, everyone knows that the reason Germany is so successful with PV is because they get more sun! Seattle doesn't stand a chance by comparison!

The cheapest thing with solar is massive massive land area at like 8-15% efficiency, with a flat nonmoving panel, that might cost a couple ten bucks a square meter, long term

I am always astounded that parking lots in hot climates - a WalMart in Phoenix, say - doesn't have a roof of PV panels. Provide shade for customers' cars and generate power at the same time. In those sunny climates, the payback period is well less than a decade.

Over 1,000 nuclear weapons have been detonated on Earth in the past 50+ years

And about half of those were detonated underground, after the 1963 Test Ban Treaty. The ban on atmospheric testing was put into place once people realized that irradiating their own planet and dispersing toxic metals was a bad idea.

Russia recently stopped all shipments of processed Uranium from Russia to America for fuel processing, a move that indicates they have no intention of reducing their arsenal.

Do you mean the Megatons to Megawatts Program? It ended of its own accord: the deal from 20+ years back was for 500 tons of enriched uranium, that amount was delivered as planned.

That the program wasn't extended seems more to be a lack of leadership than hostility. At the time when such an extension could/should have been enacted, when the New Start treaty was signed, the US was on OK terms with Russia. As the article points out, however, the hawks in the Senate stonewalled on ratifying the treaty unless they got their shiny new nuclear complex. They got what they wanted, and undercut the President's ability to negotiate further nuclear deals at the same time.

The iPhone 6 is 4.7", and might fit your hand better than the 4.7" phone you had.

Because Apple measures inches differently than everyone else?

Apple. Measure Different.

Joking aside, what you say is possible, since the screen's diagonal measurement is hardly the only metric for the size of a phone. Aspect ratio, bezel width, thickness, sharpness of corners - all of these impact "holdability"

The Dev Board that Edison plugs into appears to have Arduino R3 headers on there, presumably for plugging in Arduino-compatible shields. That's interesting, and makes a fair bit of sense: there are thousands of Arduino-compatible shields out there, and adding some serious computational power in there plus wire(d)(less) networking opens up a lot of possibilities.

The Force is what holds everything together. It has its dark side, and it has its light side. It's sort of like cosmic duct tape.

Working...
