what if you could use the lighting that already exists in your house to do this? kinda like internet over power lines?
Probably not. The summary mentions "plain old desk lamps", but TFA is specific in stating the lamps must be LED, which is still not common.
Incandescent can't be modulated at the frequencies necessary for anything much beyond S O S signals.
Of course once all your house lighting is converted to LED, your network might work provided you modulated at least one lamp in every room. This of course would leak out windows, which the Summary writer would be perfectly fine with, even tho he disparages leaking radio waves.
Also, when a flock of chickens suddenly loses it's rooster, the dominant female will sometimes act as a rooster. That isn't hormonal?
This does happen.
Apparently this is not all that common, that is, not every hen can become a henry, and perhaps TFA suggests the means by which this does happen when it does.
"Yes a type of sex reversal does occur in poultry. Both a right and left ovary start to develop in the embryo but between day 7 and 9 of incubation the right gonad ceases to continue development. If in the adult, the left ovary is removed or fails to function the right gonad hypertrophies to become a testis-organ and thus "a male' instead of what was a hen."
The implication of this is with regard to TFA is that failure of one gonad cease development leads to the double expression of traits documented in the story.
So there is nothing new here that hasn't been known for some time with regard to chicken sex other than that the normal failure to enter stasis can lead to odd birds.
Not all the command nodes are in jurisdictions that are reachable. Some peer with larger carriers from behind borders where they are essentially untouchable.
Some may represent a large amount of income for there ISPs. Some may cross the palms of their upstreams.
Its hard to cut off an entire country just because the only backbone provider has one customer that bribes them to look the other way.
The ISPs that hosted these botnet control centers had their wires cut. The entire ISP is offline. None of the companies they send their internet traffic to will talk to them any more.
Almost every bigger city has an artist community and almost any art shop will be able to point you to people who specialize in super high resolution scanning. (For a price, but its not usually unreasonable.)
How does projecting "roads" into the air clear up traffic problems? Moving a problem off the ground does not eliminate the problem.
The only source of improvement is emergency vehicles wouldn't block the roadway after every traffic accident. The wrecked cars would fall to the ground, taking with them untold number of other cars from lower lanes and landing on god knows what.
As for the "Simple collision detection sensors", good luck with that. Even the brain dead systems being offered on high end cars today trigger high volumes of false alarms, often applying brakes just as drivers were about to pass a slower vehicle.
Its easy to handwave into existance all the necessary technology to make this work. After all, Popular Science magazine has been doing it for 70 years.
You need immense pulses of power for railguns, and having a ready supply of preloaded nonotube "cartridges" could reduce the need for huge and dangerous capacitors.
But you are talking about school spending, not teacher salaries.
Your argument could be better phrased as those school districts with small class size, excellent materials, new and comfortable physical plants, in upscale neighborhoods will educate children better than poorer states.
Because 90% of Wikipedia is dead. People drive-by now and then and drop in a sentence or fix a spelling error, but for the most part nobody is editing the articles unless it's a politically contentious topic.
The fun part was writing the articles in the first place, now phase is over, nobody wants to be Wikipedia's janitorial crew and deal with the super-aspbergers that populate that place. Which is why Wikipedia is doomed to a slow bit-rot into irrelevance.
While true, one might say that stasis is the proper state for a repository of knowledge. Why should articles be under continual maintenance when the subject area is for the most part static?
Politics, religion, and anything that passes for either are the least desirable things for Wiki. Any articles dealing in either area are essentially useless, bias magnets.
But there is very little new information on the vast majority of subjects, so having 90% of them "dead" is just fine.
Equally nonsensical are the seemingly random insertion of [citation needed] tags on things that are matters of public record. Often these are used to cast doubt on an article where there is no question of fact. (I've even seen them inserted after well known figures middle name, as if there were some question what the middle name was).
Oh, excuse me, hadn't realized I stepped into the Village that it takes to raise a child.
The US/Canada has always been a society of fracturing, it is built of immigrants. Some call this a strength. But if that is something you can't live with, there is always Norway, or France.
True, but its not like the Government isn't already involved to the point that its virtually impossible to make any significant changes in our educational system without federal approval of one sort or another.
Any new method for evaluation teacher effectiveness would be studied to death. The NEA would see to that.
The slow creep of Privately run schools ("charter" schools, and their ilk) is probably the only route open to any significant change. It would allow parents to vote with their pocketbooks.
You know the best way to break a union? Pay the better employees more than the lesser employees.
As long as you're unwilling to admit that the better employees should earn as much as, if not more than, their boss, you will always be under the union's heel, and rightfully so.
But had you bothered to read the summary, (let alone TFA) you would have discovered there is no generally accepted way to distinguish between the Better and lesser employees.

Apparently One in 10,000 hens can change sex, usually in response to a gonad ceasing to function. One professor explained it this way:
"Yes a type of sex reversal does occur in poultry. Both a right and left ovary start to develop in the embryo but between day 7 and 9 of incubation the right gonad ceases to continue development. If in the adult, the left ovary is removed or fails to function the right gonad hypertrophies to become a testis-organ and thus "a male' instead of what was a hen."

Hand held? That would be a mess.
To the OP:
Almost every bigger city has an artist community and almost any art shop will be able to point you to people who specialize in super high resolution scanning. (For a price, but its not usually unreasonable.)
The file sizes will be huge.

Assuming of course you have enough of what passes for rudder to control the asymmetric thrust.
Oh, thanks, I feel much better now.
Oh, but the web page says its easy to maintain, so no doubt that overhall is all done with just a screw driver, right?
Redundant systems too it says.
Two fans. I bet it doesn't fly worth didly squat when one gives out.
Exactly.
This is one of those things that is seemingly announced annually, and never seems to get any closer than a few prototypes.
Flying is dangerous. A sky full of unregulated idiots is even more scary. Luckily the price tag is high, probably to fund the lawyers they will need.
Prevention is not at issue here, other than you would expect them to use a reliable supply chain.
The issue is having their lawyers send cease and desist orders to those revealing the story without even bothering to check it out first.

Railgun or laser power source.?
This doesn't look like a battery solution.
It looks like a railgun power source to me.

Sorry if you find the English language confusing.
The title does not change depending on where the work is performed.
Because Jr. High students aren't in a position to know how effective a teacher was.
You never realize this until YEARS after the fact. (Hence the title of this thread).
Letting students evaluate teachers would be nothing but a popularity contest - who gave the least homework and the easiest grades. DUH!
What a bunch of nonsense.
Why should ever mention of a persons name hold a reference to the county courthouse in which his birth records are stored?
But you are talking about school spending, not teacher salaries.
Your argument could be better phrased as those school districts with small class size, excellent materials, new and comfortable physical plants, in upscale neighborhoods will educate children better than poorer states.
Here, take a look at income figure.. Notice how each of your examples pretty much defines average income of the respective states?
Yet nothing you have posted offers any proof that paying teachers more will actually make them teach better.
In fact, the most often heard argument is: If you want them to teach better reduce class size.

And it worked so well with the bankers we should follow that model with teachers?
Are ye Daft Man?
Well, at least slashdotters are powerless, and can't get into your wallet, and never make anything worse.
Oh, well then, if congress is involved the problem is as good as solved, and we can all rest easy.
This isn't a term paper. You don't need to double space. Ok?

Solve THAT problem and the rest will be simple.
