GP was not talking about a 44.1 kHz sine wave, but about a 44.1 kHz sampling rate. In order to reasonably reproduce a 20 kHz signal, you'd need at least twice the 44.1 kHz sampling rate Granted, my old ears probably can't hear above 15kHz, still the artifacts produced by a 44kHz sampling rate could be heard on good enough equipment.
You seem to be comparing the bit-rate of a digital recording with a "bit-rate" calculated for an analog recording. I'm not convinced that that is valid, since analog doesn't really have a bit-rate. E.g., how much does the particle size really matter if cutting/pressing the record can push the particle an arbitrary amount. And how much difference does the absolute position of the groove edge mean anyway, since what you are trying to record are the frequencies, not the instantaneous absolute values. Further, a digital recording is quantized in the time domain, in a manner quite unlike the groove in vinyl. I'm not saying that those things will sway the argument in favor of vinyl. I understand that you're just making a rough estimate to make a point, and I won't dwell on technical issues that other commenters have covered, such as equalization curves, variable groove spacing, etc., just trying to say that I can't take your analysis at face value.
That's not saying I'm jumping on the vinyl bandwagon. I own a lot of vinyl LPs, but many are scratchy and worn, unlike my few CDs, which are recorded with redundant info to reduce issues of wear and tear.
The bottom line is that a well engineered CD could sound great, and better than vinyl. (And I don't buy those highly compressed banal pop CDs anyway.)

Although I do agree that _forcing_ the energy savings shouldn't go over too well, the rest of the comment is mistaken. Saving energy is generally good for the environment, but that has nothing to do with the issue at hand. The issue is one of short-term peak demands outstripping supply. It is definitely NOT economical to address this issue by building more capacity (even though capacity will have to increase because of separate issues about increasing population / increasing energy use). And solutions like this have been successfully used in the commercial and industrial sectors for a long time, though usually through voluntary means like rate incentives and not mandates.
. . . but God Bless Ronald Reagan for repealing that IDIOTIC 55 mile-an-hour speed limit. I don't remember what Carter's other idiotic ideas were, but Carter deserves a post-presidency impeachment for that.

There, fixed that for you

When I was younger, we made it at home from real milk, sugar and a bit of flavoring . . .
Ha, then yours wouldn't qualify to bear the label "Ice Cream", as milk doesn't have enough fat in it for the FDA.
Sadly, adding junk processed butterfat type substances could bring it up to standards.
And as far as snow flea-like food-derived chemicals, they're probably (but not necessarily) better than the propylene glycol that can sometimes be found listed as an ingredient in cheap popsicles, and occasionaly in cheap ice creams.
The traditional, old-time way of increasing smoothness is to add a bit of egg to the ice cream. I believe lecithin and gums are what are used for that purpose in factory foods.
Yep, New Jersey was definitely the license to alter back in our early college years.
. . .
We had a digital camera and colored paper (for the BG) to do replacement photos and everything
Back in my early college years, the Illinois licenses didn't yet have pictures on them, just a piece of card stock including a description like age, weight, height, hair color, eye color, etc. I wasn't 21 yet, but the drinking age was 19 for beer and wine. I "lost" my license, only to find out after I replaced it that my high-school age brother had stolen it and was a regular at one of the local bars.
And to reply to the GP, every driver's license I've ever had has had my address on it, they used to even have your social security number on them. I consider carrying a license with my address on it far less intrusive than if I needed to carry around my passport.
The precision they're talking about is probably pretty imprecise by terrestial standards; astronomers are often satisfied if they're within an order of magnitude+/-.
But the existence of dark matter is not a matter of debate: How much of the interstellar dust and debris do you think is visible? We've inferred planets that we can't see from the wobble of their stars. And, since we can't reconcile the motions of galaxies with the distributions of the visible matter (stars) we try to infer the distribution of unseen (dark) matter to explain them.
The theoretical parts of this are not that there is no dark matter, but that with our first guesstimates of what the amounts and distribution dark matter should be, we still can't fully explain what we observe.
Many theories about exactly what dark matter is and exactly how it's distributed are in dispute, but there is no dispute that dark matter exists and exerts a significant portion of all gravitational forces observed.
hy oh why do programs like Word default to turning blue and underlining anything beginning with http or containing an @
Because Word assumes that you want the recipient of your Word.doc to click on the link. MS is thinking of you, their customer, and wants to help you infect others with a keylogger or spambot.
Seriously, though, that @ thing gets me all the time when I want to call out a pump for 100 gpm at 100 ft head or an electrical load of 20 amps at 120 volts.
. . . stock holders mostly don't give squat about good will.
I worked for a small consulting firm. My boss was the sole proprieter, so there were no other stock holders to give a squat about good will, still you can bet the owner cared about good will. He sold the business in '94 in order to retire and the only asset that potential buyers had an interest in was the good will. Unfortunately for him, the buyers saw most of that good will as as much tied to his employees as to his business. Still, it was good for $100,000, a guaranteed part time job with a title and pay of Vice President, and 10% of gross from any business of his clients he brought over. (OK, an offer for a percent of business is not really about good will; but without the good will, no sale would have happened)
-- installing or increasing more air-locks/decontamination/containment/quarantine areas
Making an effective air lock is not a trivial matter (and ineffective one is easy), and not really necessary if you're in the hospital because of a non-infectious disease related matter. Already, patients that have easily communicable diseases such as tuberculosis are kept in negative pressure rooms with air locks and patients with depressed immune systems are kept in positively pressurized rooms with air locks.
-- improving anti-bacterial ventilation and air cleaning/recirculation equipment
Air handling systems serving patient areas are already required to include HEPA filters, which must trap at least 99.97% of particles below 3 microns in diameter. That's smaller than all but the smallest bacterial spores. While viruses are small enough to get through the spaces between the filter fibers, a large number of particles that small are absorbed by by the fibers by diffusion. Some air handling systems also include ultraviolet lights capable of directly or indirectly killing mold, bacteria, viruses, and spores in the equipment.
-- setting up scanners points to look for flush/sickly people who emit fumes of certain bug signatures
?? How is that to be accomplished ??
-- make the doctors and staff ALL wear anti-microbial/bacterial surgical masks EVEN FOR NON-SURGICAL visits (hey, they may be amped on anti-biotics, but aren't they still carriers?)
The main problem is with multiple-antibiotic resistant strains of germs. Indiscriminately throwing around anti-microbial chemicals is a contributing factor to the development of resistance. (and, hey, if they're amped up on effective anti-biotics, they shouldn't be carriers)
-- emulate (if not doing so already) practices of the travel/cruise industry which separates various linens according to bacterial or viral risk
Isn't it the travel/cruise industry that's emulating the health care industry? There are already stringent requirements for the handling, washing, and disinfecting of linens in hospitals, and much of that includes throwing things away rather than resuing them.
. . . hospitals and clinics should not be "walk-in-as-you-will" facilities. They should have screening or quarantine areas to separate and manage ENTRY of DETECTABLE vermin/air-borne agents.
What, are you going to turn away "walk-ins" from a hospital because you can't prove they're not infectious?
Anyway, more and more emergency rooms are being equipped with (properly ventilated and disinfected) isolation rooms to hold potential problem patients while being evaluated. But other than diagnosing them, I don't know how you're going to DETECT vermin/air-borne pathogens,at least not in real time.
I work for a consulting engineering firm in the construction industry, and I've designed air handling and filtration systems, ventilation for isolation rooms, and even laundry systems for hospitals, among other things. I've also worked in a hospital in my youth, and was given the hand washing lecture: 20% of the people in hospitals get infections that they didn't come in with, and the majority of those could be eliminated by properly washing hands.
Apple might be good for a grandma or for a graphic designer, but for a programmer it's an annoyance.
My son who uses a Mac laptop might disagree. He's a graduate student studying artificial intelligence and tells me that Macbooks are the most popular laptop in the computer science department (of course most of those dual or triple boot XP, Vista, or Linux, after all, they get free licenses)
Sears have had their problems in the past, but what they are since K-Mart (well, Lampert, really) bought them out is not the same Sears anymore.
At one point in the past (the '80s, when I first started dealing with them as a consulting engineer on construction projects), Sears was a huge conglomerate, the largest retailer in the world, the owner of the tallest building in the world, of Allstate, Homeart, and Dean Witter, among other companies, and the creator of Discover Card. But their "core" retail business was threatened by cheap dicount department stores like K-Mart. Sears changed its mind about once a year on whether it should compete as a discount chain, or distinguish themselves from the discounts as a better, more upscale place to shop. While confusing shoppers that way, the cheapest of the cheap, Walmart, snuck up on both Sears and K-Mart and passed them both up.
Still, though their retail business barely made a profit in good years, they were profitable overall because of their other businesses. But, shareholders, at least a few of the bigger individual investors, insisted on splitting up the conglomerate, and get Sears to "focus on their core business", retail. Though that proved bad in the long run for Sears, if you were a stockholder, you made gobs of money from the stocks in the spun-off businesses.
The final straw was when Lampert bought the bankrupt K-Mart and used it to buy Sears and creating "Sears Holding". The stock of Sears was undervalued because of their poor performance, but they have value because of all the real estate they own. You can be pretty sure that Lapert will squeeze what he can out of the assets and leave little for the customers or employees.
95% of the fuel used in fission plants can be reprocessed
. . . into fuel for nuclear bombs.
That's the main political problem. Current methods of efficient reprocessing are actively discouraged because they produce fuel that can be easily processed into bomb-grade materials.
Ab sorption chillers use salt solutions, usually of lithium bromide. They run at much lower temperatures than stated in the summary, typically somewhat over the boiling point of the salt solution at high pressure. I've never seen one using solar power, though I have seen them using natural gas, waste gas from a landfill, waste heat from electricity generators, and steam.

GP was not talking about a 44.1 kHz sine wave, but about a 44.1 kHz sampling rate. In order to reasonably reproduce a 20 kHz signal, you'd need at least twice the 44.1 kHz sampling rate

You seem to be comparing the bit-rate of a digital recording with a "bit-rate" calculated for an analog recording. I'm not convinced that that is valid, since analog doesn't really have a bit-rate.

And how much difference does the absolute position of the groove edge mean anyway, since what you are trying to record are the frequencies, not the instantaneous absolute values.

You've got it all wrong, It's Propylene Glycol that's a common food additive, not ethylene glycol.
Sadly, adding junk processed butterfat type substances could bring it up to standards.

A missing watermark is evidence that you don't have an authorized copy.
On the other hand, if it's destroyed by compression, then lack of a watermark in your fair use copy may not be reliable evidence.
