I wonder if this would make possible the following:
Here is Encrypt(www.slashdot.org), please compute Encrypt(DNSLookup(www.slashdot.org)) so that I can then Decrypt(Encrypt(DNSLookup(www.slashdot.org))) to produce 216.34.181.48.
But the output is encrypted. So basically you give them your sales data ( encrypted ) and they compute the results ( encrypted ). They can't understand the results they produce. Only you can decrypt the results and make use of them.
It's orders of magnitude easier to live at the south pole or deep under the ocean than it is to live on Mars. And it's orders of magnitude easier to live on Mars than any other non-Earth body in the solar system.
Until we've run out of places on Earth to colonize which are easier to live on than Mars, there is absolutely no compelling reason to colonize Mars. Explore, sure, but not colonize. To have a colony it must be completely self supporting or be capable of making a product the parent country/world wants which is valuable enough to justify transport. The only such product is knowledge which can only be obtained by exploration. Once the knowledge is transferred, the colonists no longer have anything of value,and would die of starvation/asphyxiation when supplies from Earth stopped arriving, and their last rocks2air maker broke.
I live in the US. My family doctor is one of many at a Family Practice. If I am getting a physical, then I get 'my' doctor, but if I am sick, I basically get whatever random doctor has a free slot for a short notice appointment. The doctors all have access to the same computer system with my records on it. My doctor doesn't remember my face among the zillions. Why should he?
Seriously. I am not joking. They don't know what is good for them most of the time. Neither do developers, but by innovating and finding out what works, that's how improvements that do work are winnowed from the chaff.
Giving users what they want is often like giving your 4 year old what she wants for breakfast. She'll choose the donut and candy breakfast of champions every time. You have to show her what she really wants because she is 4, and you know of better and more wholesome things than she can even imagine to want. Once she's introduced to them, she'll be greatful because they really are better. Sometimes grownups know best.
I'm thinking of tools like the command line, emacs, and vi here. Users don't like them. They require some chewing, but once you learn to love em, they're much better for you. In the long run learning them will give you increased productivity not possible in the world of ooey gui candy. But even gui tools, follow the same pattern. Children ( novice adults ) don't like them at first if they're any good.
It doesn't seem nearly as surprising that the levels of CO2 in the atmosphere are being raised significantly as a result of man made emmissions of the gas, as that the carbolic acid levels of the ocean would be significantly changed.
The atmosphere seems so light and airy compared with the dense and vast oceans. A gallon of air weighs almost nothing, whereas a gallon of water is frikken heavy!
What would the atmospheric pressure be at what is now sea level if the oceans were boiled into steam? It's probably many many times 14 lbs/sq inch. ( Actually I have no idea but that's the feeling my intuition gives me. )
I guess the numbers have been run, and the CO2 in the air is enough to account for the acidification, ( gotta give em the benefit of the doubt unless you're willing to do better ) but wow man.
Well the 20% would be less if more people wanted 1g wafers. The means for providing them would become more efficient.
In fact anything over ~10% markup seems to be premium being charged for the novelty, and convenience. People who go to these vending machines probably wouldn't have gone through the hassle of seeking out the same thing though other channels. And the product likely has the company name, purity and weight of the gold stampped onto it. It's a (privately minted) coin.
It makes sense to accept this coin as being what it purports to be because it's kind of hard to fake. It looks like gold, it's heavy like gold, and it has been manufactured to appear to be gold of a certain purity and weight.
Someone could go through the trouble to fake this, but it wouldn't be trivial. And they would have to be willing to commit a crime (fraud) to do so. So if someone tried to pay me with 50 bucks worth of gold minted into a coin, then I'd likely accept it as readily as I would a $50.00 bill, especially if I'd seen such a coin before, and were familiar with the vending machines.
I would certainly do so if it were possible to put coins back into the vending machines and get credits for currency deposited on my debit card.
Vending machines already verify that money is real, why couldn't they verify the goldness of coins snapping a picture of you and recording your name ( on your debit card ) to prevent money laundering.
The question is whether the premium attached to holding gold should also be credited to the gold depositor valued in currency, or remain with the operators of the vending machines. 1 gram of gold coins should be worth more than 1 gram of gold. The machines could/should offer the service of verification for free. You insert a coin, and the machine tells you if it's genuine and it's true weight.
The operators of the machines might choose to keep the premium as a way to make money. This would discourage people from depositing gold at all, and keep it in circulation, increasing it's appeal as it became more ordinary for people to use. Because they charge a high premium they concentrate not on having convenient machines all around, but on selling the gold coins.
Maybe national governments could get in on the game, as they have recognizable stamps to put on coins already.
What if the US for instance minted 1 dollar gold coins containing say 1/9 oz of gold charging the spot price of ~ $100.00 for each coin plus whatever minting premium the market would bear. The coins should have the denomination ( really used here as more of a trademark ) and also the more important purity and weight of the gold, as well as LEGAL TENDER. They would be legal tender valued at $1.00 but only an idiot would give one up for a dollars worth of goods.
I wonder why the DoD wanted to be able to retrieve sattelites intact unless they had nuclear material on them.. Maybe there were sattelites with nukes orbiting the earth at one time... Probably not though. They probably just planned it to make some of the Star Wars junk they were scaring the Soviets with seem more plausable. I mean we wouldn't send up a sattelite with nukes ( such as that once planned sattelite that would explode a nuke to generate an X-Ray Laser to shoot down ICBMS. ) if there were no way to retrieve them. You wouldn't want to shoot it down ( or have it fall out of orbit ) with nuclear waste on board.
With no more manned space program to sap the funds from all the very worthwhile space exploration and science, we could be doing, there will be that many more discoveries made.
Except that the money will just disappear into the general fund. Still, it's better than completely wasting it on manned space missions.
In this case our daughter is 3, and so can't play WoW, and her play till sunup behaviour means she sleeps till noon and doesn't even get her breakfast. then she's cranky from lack of sleep on top of her unpleasant sharp temper. I don't care if she ignores me, and her while I'm home, but can't abide by the neglect while I'm at work, and she won't get a job. Now she'll have to.
I played a couple of characters, I got one to level 17, and one to level 9 or 10. I honestly found WoW boring, repetitive and basically not very fun.
And I used to be quite the gamer back in the days of FF7..
My how things have changed. My (soon to be ex) wife however has basically chosen WoW over our marriage. Whatever. She basically obsesses about one thing to the detriment of everything else in her life, and I've had it. Before WoW it was backyardchickens.com and if it wasn't WoW it would be something else.
The oxygen combines with the lithium and stays in the battery - it's a solid i believe. Then when you recharge it, the oxygen goes back into the atmosphere - don't recharge in a confined space while smoking.
A fuel cell is an electrochemical conversion device. It produces
electricity from fuel (on the anode side) and an oxidant (on the cathode
side), which react in the presence of an electrolyte. The reactants flow
into the cell, and the reaction products flow out of it, while the
electrolyte remains within it. Fuel cells can operate virtually
continuously as long as the necessary flows are maintained.
Fuel cells are different from electrochemical cell batteries in that they
consume reactant from an external source, which must be replenished ^[1]
-- a thermodynamically open system. By contrast batteries store
electrical energy chemically and hence represent a thermodynamically
closed system.
This thing is sort of half way to being a fuel cell, the air flows in, but the fuel and reaction products also stay in.
I wonder if one's laptop gets significantly heavier with one of these batteries as the fuel is oxidized since the reaction products include both the weight of the fuel and of the oxygen used to burn it..
"Man, I've been working all day and this laptop feels like it weighs a ton" " It does!"
As has been said before, the guy who shasums a MyPet01.txt file and submits it to every site is giving the support people at every site the means to bypass all his password protections since that will be stored cleartext.
Not filling them out is dangerous. If you don't fill them out then a question is selected by default. No answer is still an answer. A reasonable guess to 'the answer' is nothing, or rather, I didn't fill it out.
I imagine an operator asking: What is your mother's maiden name? Then the perp being stumped, and after a period of silence, the operator determining that the question was answered correctly.
And a machine is almost guaranteed to be that dumb.
Yeah, that's my question, but I type in a bunch of crap I don't bother to remember as the answer. Basically, If I lose my password I'm toast, but nobody's going to guess the answer to my secret question, not even me.
In most cases speed is not a compelling reason - even at 'OS Level'. Premature optimization is the root of all evil even there. If speed is not obviously a compelling reason, then don't prematurely optimise for speed. Use performance profiling to optimize only where it actually helps. I think 'at OS Level' means it's easier for developers to hand wave about speed when there was really no compelling reason to make things complicated and/or error prone.
I should have said a higher level library. If you're doing high level programming in any language use high level libraries. If you truely need to get down to the bare iron for some COMPELLING reason other than 'I just felt like it' then use lower level libraries.
In almost all cases there would be no performance penalties. In a few cases there would be slight performance penalties. In a very very few cases, there would be significant performance penalties. In those cases use whatever works and be very careful.
