You must be new to IT, or at least networks. "Cloud" isn't new at all. Network diagrams (going back at least to how DEC drew DECnet ones) have long used "grey clouds" to indicate areas of the network where the internal details weren't important to understanding. So, "cloud" in relation to networks has been used for 30+ years.
So, "cloud" services are just ones that are out there in that cloud - you don't necessarily know or care the exact network path to the service, it's just at the other end of some pipe (oh, that's another networking term you should get used to - we don't use real pipes, either).
Being generous, and assuming polarizers consume 75% of the available light, and the light-voltage conversion is 30% efficient, aren't OLEDs already more energy efficient?
Since this is based on organic technology, why not just use an OLED display, and avoid wasting that energy in the first place? (assuming that this would add costs similar to the LCD/OLED delta, or greater).
The whole point being, it's always better to reduce energy use, than to try to inefficiently recapture otherwise wasted energy.
There's nothing in the article to indicate that the energy capture on this technology is variable. If you can't control how much dimming these provide by capturing photons, on an individual basis, then your point is moot.
I thought perpetual motion was settled a long time ago.
The only way converting backlight to energy works is by stealing photons (effectively dimming the display), and putting it through a level of inefficiency. Better to just adjust the display backlight to the appropriate level.
I've broadened by navigational horizons. First, by turning on "Avoid Highways," which exposes you to side roads. Secondly, I've found that GPS can show you shorter routes you might never have found/taken because you chose the simple/easy route.
How is it calculating to punch numbers and symbols into a calculator to get a result? Sure, the calculator is doing math, but that's hidden from the user.
Even if you limit the class to Verizon 4G Android phones, this isn't new or unique. Inductive charging is already available for the HTC Thunderbolt and LG Revolution.
"DNA not only identifies you, it identifies your siblings and your entire family?"
Which, if your family is native to the US, is already a matter of public record, so what's your point?
Furthermore, I assume that they're actually cataloging the DNA markers which allow statistically unique identification, not sequencing the entire genome. Those markers have been chosen so you are unique from your parents and siblings.
How does this differ from collecting fingerprints at arrest? Because they draw blood (I'm assuming that's what they do)? How about if they brush their hair, and keep some follicles?
At least in my state, fingerprints are collected upon arrest, but are supposed to be destroyed if there is no conviction.
Next thing you know, IT departments are going to have to get rid of their IBM 360 mainframes and DEC PDP-11s, and start supporting those new-fangled "personal computers."
Calm down. I didn't claim anything different. But, the majority of the Federal debt isn't sold to/held by the Federal Reserve, it's held by other governments, mutual funds, pensions, etc.
"A very accurate time can be determined from WWV by synchronizing with the carrier frequency."
No, it can't. Frequency != time. Besides, even frequency from the NIST stations is only good to ~1e-7, as received. With much effort, you can get to about 10e-10 in a month. You can do a couple orders of magnitude better with a GPSDO.
WWV, et al, work on HF, and are subject to significant propagation delays. You can get much better time from the GPS constellation (25 ns, pretty easily). To get into the inch/centimeter range, you need sub nanosecond accuracy.
FTA: "The researchers sent a follow-up survey to their student participants asking them whether the first five digits of the social security number their algorithm predicted was correct. "
SS numbers are 9 digits long. Matching the first 5 digits isn't matching 9 digits. The first 3 are associated with place, the second 2 are fairly predictable based on when the SSN was issued, but the last 4 are just assigned sequentially. Also, there is no requirement to get an SSN shortly after birth, so SSNs aren't even necessarily associated with birth date.
"The US government should have minted two $1 trillion dollar platinum coins, thus creating debt free currency "
Don't be silly. It's thinking like that which brought us to the financial problem we're in. Creating money from nothing doesn't avoid creating debt, it just causes the debt to payed in monetary inflation. Really, instead of just minting 2 coins, why not 300,000,000 of them, and send one to everyone - we'd all be trillionaires, and then they could pay off the debt with the taxes we'd pay on that income.

"their own backlight into energy"
I thought perpetual motion was settled a long time ago.
The only way converting backlight to energy works is by stealing photons (effectively dimming the display), and putting it through a level of inefficiency. Better to just adjust the display backlight to the appropriate level.
No, it's more like a car being advertised as having a 200 hp engine, even though drivetrain losses result in only 170 wheel hp.
"Exthort?" Really?
...and the Commodore PET, and the TRS-80, and the Sinclair ZX-80 and the Commodore 64.
at least to me.

it looks like a mashup of Opera's Speed Dial and the embedding/customization of Apple's circa-1996 Cyberdog.
