"Saying that the government subsidises the USPS is no more true than saying that the government subsidises the Catholic Church."
Actually if person A gives money to the Catholic or any of a number of other churches, they can take a tax deduction, which means that person B, who spent the money on a new TV or something, gets to pay a little more in taxes to make up for person A paying a little less. So the government isn't subsidizing the church, but they're making the non-church goers do so.
They are exempt from state and local taxes because they're on federal property, just like military bases. They don't run that flag up the pole every morning just for fun.

"Voltage is just the 'speed' the current 'flows' at..."
Wrong, wrong, horribly wrong. An interesting analogy, but fatally flawed. Even if you start from the premise that the "speed" at which current flows varies with variations in voltage, that's still not the definition of voltage.
Voltage is the expression in units (Volts) of electromotive force (the E in E=IR, Ohm's law). It's how much difference in electrical potential exists between 2 points. If a conductive path is established between those 2 points then the E will cause the flow of current (I, expressed in Amperes).
How much current flows depends on the voltage difference between those 2 points and the conductance of that path. The conductance is usually expressed as its mathmatical inverse, resistance (R, expressed in Ohms). The higher the resistance, the lower the current.
How fast that current flows will be somewhere just a little shy of the speed of light and will be pretty much independant of voltage level.
To get a certain amount of current to flow through a given resistance a certain voltage must be applied across that resistance. The amount of power, measured in Watts, is the voltage times the amperage. 10 Volts will drive 1 Ampere through 10 Ohms for a dissipation of 10 Watts, or 10 Amperes through 1 Ohm for a dissipation of 100 Watts.
If one is talking about AC (alternating current), then the power equation (P=EI) has to be modified to take into account the continuous change of voltage and amperage over time, as well as another kind of opposition to the flow of current, known as reactance, which changes as the frequency of alternation changes (and whether it increases or decreases in response to an increase or decrease in frequency depends upon the presence or absence in the conductive path of a couple of other electrical characteristics), but for household stuff the DC equation can still give you a rough idea of power consumption, or a way to figure average current by starting with the Watts and doing the math backwards.
Often the Supreme Court removes a whole bill if an unconstitutional bit of it is inseperable from the rest..."
I find it troubling that they could do anything else, i.e., declare part of a law unconstitutional and leave the rest of it in force. When the law was voted for by a sufficient majority of the legislators and signed by the executive, it was the entire law. Some of the legislators may have voted for it by way of compromise because they were willing to accept the parts they didn't like in order to get the parts they did like. Same for the signing of it by the executive. Disabling part of it is the equivalent of breach of contract.
The Star Trek episode in question came about 10 years before the Chrysler ads. They were more contemporaneous with Montalban's role as Mr. Rourke on Fantasy Island.
"How often do shows get shifted around to make it an inconvenience, though?"
Every damn chance they get!!! Especially if they notice that the show of theirs you want to tape is one of the few not already on at the same time and day as the ones you want to tape on the other channels. I have almost too many VCRs to deal with as it is, if I wanted to put consecutive episodes of the same show on the same tape and whatever show follows on a different tape (like say "Fastlane" and "John Doe" or "Enterprise" and "Twilight Zone" or various PBS stuff or whatever) there wouldn't be enough room in the house for all the separate VCRs I'd need.
"Does anyone remember the HardCard? It was a hard drive + controller on a fullsized ISA card. I had one... I still might have it in my 286, I wonder where I put it?"
"one thing you can't do to real radio is have too many users.;-)"
The word "broadcast" does seem to have acquired a wider range of meaning than previously. I was wondering where they got the money to operate several actual over the air radio stations. Apparently they didn't. Perhaps a new word for over the air broadcasting and only over the air broadcasting is needed.
"If everyone sat around and ate "shreddies" while watching TV, there would be much less violence in this world, the problem is that people put down their toys and picked up guns."
I think you'll find that people without TV, toys, or enough to eat are often a big part of the causes of wars, if not by acting out of their own desperation then by having that desperation exploited by others for their own power-hungry ends. War isn't always the result of people with options preferable to violence choosing violence anyway.
What I was talking about is getting a RoadRunner cable modem account, an AOL cable modem account, and an Earthlink cable modem account (all of which are available over my cable company, Time-Warner), without having to install 2 more runs of coaxial cable (for a total of 3) from the pedestal out at the street back to my house, and then somehow "bonding" all 3 cable modem feeds so that each carries part of each upload or download to reduce the total time necessary, similar to the system of dual modems, each with its own phone line, that I originally respnded about.
Please note that I'm not really interested in paying for 3 cable modem accounts, it was more of a joke.
I'm also somewhat reluctant to put my internet connectivity at the mercy of Time-Warner, having experienced their cable TV service these many years.
So would it be ethical for me to start publishing out of copyright works and either not credit the original creator or, even worse to my way of thinking, claim that I am the creator of the work? Would it be okay for me to find an out of copyright dissertation and submit it as my own work to get a doctorate degree?
Sounds as though while Fox may have no grounds for action Doubleday may very well have and I'd love to see them (and perhaps Eisenhower's descendants as well) burn Dastar a new one, just so that they get the punishment they deserve for not giving credit where credit is due (even if monetary payment wasn't). This isn't so much copyright infringement so much as it is plain old fashioned plagarism.
And in other news Slashdot user Jonathan Swift's post "A Modest Proposal" was also modded as "flamebait".
One wonders why this story isn't considered important enough for the main page. Will these seized computers ever be returned to their owners or will they wind up being sold at police auction? Even if the police can prove in court that they (the police) did not doctor the photos, can they prove that the photos weren't doctored before being seized?
"still gotta have swiches otherwise its a giant hub with all connected to all"
But does there really have to be a switch at every transformer, or can they be located upstream at the transformer that feeds that (and other) transformer(s)?
That computeruser article, though interesting, doesn't say anything about the lower and upper frequencies of the signal imposed upon the power lines, or the voltage at which those frequencies would be imposed. It does, however, seem to indicate that this is designed to push bits down the lines to the subscriber but not necessarily up the line from the subscriber. Yet another way for The Powers That Be to deliver Pay-Per-View is not exactly what I'm looking for.
Yeah, but the important question is whether Time-Warner cable, who offer RoadRunner, AOL, and Earthlink over cable modem, can give me all three over the same single piece of co-ax that we get our TV over.:-)
If neither AMD nor any other company were competing with Intel we'd be awaiting the debut of the 486 "real soon now". Even Moore's law depends on competition to drive semiconductor manufacturers to continually develop the new techniques and technologies necessary to be able to double the number of transistors per unit of area every 18 months.
"Besides, if you've got a (mostly) pure sine wave at 50Hz, and you're using that as a carrier for a much higher frequency signal,..."
then all you need is a low-pass filter to pass the 50 Hz and severly attenuate the high frequency signal (or a high-pass filter to do it the other way around). A notch filter (an inverted bandpass filter, basically) is unnecessary, and unnecessarily expensive, overkill.
"The US uses induction transformers, how will the signal get through the transformer?"
The power company transmits a 60 Hz "signal" through those transformers just fine. The question here is how much higher in frequency a signal can also be efficiently coupled from one winding to the other. The higher the frequency the greater the bandwidth possible.

"But his trucks only drive on the surface of the road, so they won't damage the roadbed at all."
Excellent, in the sense that it shows how ridiculous the claims are, analogy.
Don't you just love the way they imply that the data can ride the magnetic field and get to the other end a lot faster than the (large sized fraction of light speed) current that creates that field in the first place? And leaves out that once the field is changed in any way by the data waveform it will "back-EMF" that change onto the current?
