But it's not protected from denial of service. If tampering alters the entire bitstream, is there any error correction method that can self-correct if there is a non-zero probability that any bit in the stream could be wrong?
Someone's probably going to have to come up with some sort of orthogonal method of information propagation with photons, sort of like a fourier transform of a signal from time domain to frequency domain, where the information is transformed from the photon stream to some other realm which isn't affected so much by the actual delivery and integrity of the photon stream.
Doesn't this then just simply open the door for someone to put a tap on the line just to keep the message from getting through, because if peeking at the photons perturbs them, does this not lead to a loss of information in a real sense?
You get bent by the IRS if you are underclaiming your total income, unless you are completely volunteering. In this case, they still have to declare their stock incomes, capital gains from stock sales/options realizations, etc., on their tax forms, and probably any other fringe benes they will still get from Google.
But taxes are weird for company owners compared to regular employees, too.
Yes, if you're self-employed, and you under-report your income relative to your company's income, you will probably invite unwanted attention from IRS Agent Smiths.

Our most likely enemy, China, is 30 years behind us in military technology and the two gulf wars have shown the superiority of precision weapons over masses of infantry and tanks. India, which seems to be advancing faster, appears to be doing so because they have been so far behind.
But for some reason I think there are a lot of French, and to a lesser extent, other European, military companies that would be more than happy to sell their tech to China, if just to shove a red hot poker up the US's ass, even if it means that the red hot poker might end up in their ass sometime later.
Had Saddam Hussain not been so stupid, some of the tech he had bought from France, Germany, South Africa, et al. in '91 could have given the US a far rougher time than it did. But alas, he stranded his bullet sponges...er, cannon fodder...er, conscript infantry, in trenches for weeks, only to be pummeled relentlessly by B-52 carpet bombing and BLU-182 drops...
Funny, I was just reading an article the other day that the funding for the supercomputing centers (SDSC, NCSA, etc) by the NSF was going to be up in the air in a couple of years...
People live up to, or down to, the expectations placed on them.
In the US, I would say we're doing a good job of making sure people live down to them...
People bitch about "new textbooks" for static subjects like mathematics and basic science, english comprehension and vocabulary, etc.
Others worry that w/o computers in school, their kids won't be able to find jobs when they graduate because they don't know how to use computers.
Having experienced working with older "non-traditional" college students (Univ. of Washington, Bothell, 1991-1994) in a computer lab, most people figure it out soon enough. Solitaire and Mindsweeper are the two main aptitude applications one must master, and "using the computer" is 80% done.
95% of computer users do not use styles or templates. about 20% of them (young and old) would manually try to paginate their papers, and be baffled when the hard page formatting for their home printers was completely fucked up when they printed out at school.
My kids (6 and 4 yrs old) need to know how to program computers? Not really. I hope that they learn algebra and basic calculus, as well as have a good hand at mental arithmetic, just so that they can think symbolically and abstractly. I also hope that they end up liking to read.
But if they can use Windows, er, a "computer"? Please. They will learn that by osmosis.
Thomas Edison and Benjamin Franklin would not have circles run around them by anyone, and I'm sure if they were able to read your post they would simply quiver that the thought you yourself were a CS student
No, they'd be ROFLAOUTV (rolling on floor, laughing asses off until they vomit).
Agriculture, entertainment and industry account for a huge chunk of the US
Depends. Just ask a sheep rancher. Bolliwood (sp) makes 10x more movies per year than Holliwood, and reaches more people (OK, most of them are in India).
Niche markets survive in the US (mini-mill steel vs. Big Iron), but there is heavy pressure to send scrap steel to China, which is then sold back in the US cheaper than US producers can make.
Other countries will kick US' ass in basic ag commodity production, because they don't have the labor costs or environmental restrictions.
I like the environmental restrictions, because I see them as a form of mandated efficiency for the whole economy, not for the farmer. Fewer chemical bad effects 5-20 years down the line more than offsetting any short-term gains), but I think it would also be fair for the US to insist that imported commodities meet the same standards.
Hey, if Japan can get away with the same line of reasoning against US imports...
Does it suck? Sure. But America has shown in elections it doesn't want European-style high taxes to pay for stuff, and when you can't pay for stuff, you can't have stuff.
But does it suck more to have to pay for things you don't want?
Oh well. The Republican side of Congress, and now the Administration, has shown it doesn't really care much what the majority of people think (how many of the polls were really in favor of the HoR continuing with their impeachment proceedings against Clinton?), and how hard will the Prez continue to pound sand w.r.t. SocSec reform (why not instead lower the rates, and boost the limits on IRAs/401Ks/etc.)?
The only people who don't mind the current tax structure (even as they bitch about it) are the ones most able to dodge it.
Also, we fought and won a cold ideological war of a much starker, more manichaean nature against communism that lasted fifty years. And the commies had nucular weapons. If you're old enough to recall, the arguments among the allies were much the same ("cowboy" president, "reckless" policies, the British PM being a "lackey" or "poodle", etc), and they're as stupid now as they turned out to be then.
Whatever. But in some cases we're against perceived grudges that have a couple of thousand years' history behind them. Hard to just roll that back instantly.
Just go to Atlanta, GA, and openly say something smart like, "Sherman should have kept going..."
About as smart as wearing orange to a Saint Patrick's Day parade in Chicago or Boston.
The red light cameras deserve to go in. The speed trap cameras don't.
Accidents go up? It's because people are used to zooming through an intersection 10 seconds after the light turns red (saw enough of this in San Diego, LA), and aren't actually expecting someone to stop correctly.
Funny thing is, cops in the traffic flow probably do more to prevent accidents, but of course, they reduce revenue, because everyone is behaving.
When a car passes over the loop the magnetic field changes and the system knows a car went over. Not only can it count cars, it can tell the size of the vehicle (motorcycle v. car v. truck) and estimate the speed and direction.
It takes more than one loop to calculate speed. Sure, they can guestimate size of vehicle, but that's about it.
This is usually to help control traffic lights so that the light doesn't sit on red when there are no cars there.
They're also cut into the highways to monitor average traffic speeds and count car flux. But now they're using cameras and computers to do a lot of that, even for intersection control.
It also is used in apartments and mini-storage areas to let cars out and shut the gate behind the car to prevent tailgaters from sneaking in.
This is a pretty old use of induction loops...
Somehow, an antenna buried inches in tarmac or concrete doesn't seem like a good way to read RFID tags.
Criminals could set up readers around police stations and record tags from police cars. Then they could setup readers around their "areas" for a early warning system.
Some are called "scanners", and others are called "radar detectors".
Another network is called "citizen band radio".
Criminal organizations just need to use "screwdrivers" to remove license plates.
Here's a great prank to play on someone: take their license plates off of their car, and throw them away. The cops *WILL* pull them over, and probably drag them to jail while they sort out the "someone stole my plates! really! It's my car! See, it's my registration!" later.
I saw within the last year, though, a show about the so-called "mimic" octopus, which I think this is an example of. It's kind of small, but it quite literally mimics other creatures rather well, both in coloring and behavior.
A rather remarkable little creature.
Also amazing about octopi is that the coloring cells on their bodies are, IIRC, directly mapped into neurons in their brains. No ganglia, etc., to combine signals in.
sprinkler heads aren't even electronic. They have metal plugs that melt at a given temperature, which releases the water and the pressure drop by one sprinkler going off usually will set off several others in the same area or zone. The pressure drop is also detected by pressure monitors hooked up to the fire alarm system.
Don't want students to hack into the building management system? Simple, then. Just have that system dump its data to a secure store, and have the accounting system read that data. You don't want a live feed off of the HVAC monitoring system anyways.
The utilities and industry use SCADA to gather data from instrumentation and equipment. Then you just need the system that aggregates that information to report to F&A (finance & accounting).
As long as it's a one-way system, then the only risk for hacking is some knob futzing the info and making fraudulent payments, not screwing up the HVAC in a lab with a critical experiment, a hospital ICU, etc.
Look (how I think you will think I look with it) and feel may be first, but then comes imagined/perceived/possible utility, and a distant third, whether it's actually the best tool to do what it will actually be doing at the right price.
So, using CSS, someone could probably do it with a series of overlapping images, right, and just pop z-orders for the images as the mouse pointer approaches the "icon"? Or maybe use a clever image-scaling JavaScript function, possibly invoked by code that ensures only the icons adjacent to the pointer are being actively scaled (and let the browser move the pieces around), and not evaluating the entire strip of icons?
I take the design specifications from the customer and give them to the engineers. You don't want the customers talking to the engineers. I have people skills!

GM's "X Frame" concept is pretty innovative, but it depends on a hydrogen infrastructure.
The new "hybrid" GM pickup truck is not innovation.

Uh, no it won't. And an M-1, with the governors removed, can do 60mph+ on the road or in the open desert.

1936. Remember, that's quite some time into the automotive revolution...millions of Ohioans had driven without licenses till that point.

Furthermore, he says, grass is perennial, does not require fertilization and can be grown on marginal farmland.
No, only some grass is perennial. Many others are perpetual, but they're botanically speaking, annuals.
