A "Russian Troll" that is saying "let the market handle where and how those resources should be managed" ?
LOL, well if the Russians have come over to capitalistic principles from communism, I guess we have come full circle, because the USA has been walking away from capitalism for decades.
When business becomes over intrusive into our lives, who else can you turn to but the government? When business says it's more profitable to lock it's workers into a warehouse with poor ventilation and no fire safety equipment (that costs $$!), who else can you turn to but the government? When business feels they can sell you a product that they know will either kill you or it does nothing at all, and feels it's your problem for buying it, who else can you turn to but government?
Government is what it is because it's been cleaning up Capitalism's messes since we started this country.
Oh yea, you DIDN'T read what I said now did you, you heard what you wanted to make your argument... The straw man that it is.
Look, I said government should be as unobtrusive as possible, I DIDN'T say non-existent. There are problems for which government is the ONLY tool, but I'm trying to point out that if the problem is a screw, then government is a sledge hammer. You can insert a screw with a sledge hammer, but the results are not pretty.
The tool we call government is a blunt instrument yet we insist on trying to solve surgical problems with it. It's like trying to replace a surface mount IC using a 100W trigger Weller iron. Sure, in theory it should work, but in practice you are going to destroy 99.9% of the circuit cards you try it on.
Government is a solution that should be your LAST resort because it's horribly ineffective and inefficient at nearly everything it does. We've made it our first solution for nearly everything now, and are paying the price in taxes and freedom while getting inferior service.
So if you think having laws to prevent a warehouse full of people from going up in flames actually work, I have a number of recent examples of this not being true, in the USA even. Sure they may help, but might there be other options that are as effective but don't cost tax money? I think there may be, but we already have "fixed" that one with a government program, and people keep dying in similar ways....
And when all the businesses collude to fuck your ass with a rusty nail, to whom will you turn?
You turn to YOURSELF.. What part of build something better don't you get. If businesses insist on mistreating their customers, even if they collude with all the others providing the goods or services in question, then YOU build a business that DOESN'T and you will win the game and others will be better off for it. Look, building a business may be hard work, but if everybody out there is abusing their customers what's YOUR excuse? You don't want to try?
There isn't a business out there "too big to fail" or "too big to be beaten" if things are as bad as you want to think.
You are basically saying that we are ignoring the Constitution... And I agree with you. Government needs to be as unobtrusive in our lives and businesses as possible, yet we've made it into the one organization that controls everything imaginable. Our constitution was not written to do this, quite the opposite. We may no longer have a king to pay tribute to, but what we now have is far worse, a government run on regulations written by unaccountable bureaucrats that demands ever more tribute (taxes) be paid.
Man.. You just had to bring up a Nazi reference didn't you... Usually that means you are losing the argument, but in this case I think you actually won the point. Well done there AC.
Sir, I know you are now faced with your own mortality and like everybody, you want to believe that your life, once over, had meaning. Where I totally disagree with your atheist world view, I want to offer you the following assurances...
Professor Hawking, you have already changed the face of physics and will be remembered for your brilliant contributions until the end of time. Your legacy is secure. You will be remembered in the same breath with Einstein, Planck and Newton. NOTHING will change this. Please rest assured that you have indeed lived a life with significant meaning.
Professor, Given the above, there is no need to embarrass yourself with these lessor topics like the existence of alien life and artificial intelligence taking over the world. It only makes you look the fool when you get involved in this stuff where you are assuming you know the future. These things only serve to tarnish your previous contributions to mankind and are not necessary. I urge you to stop.
Well. if we apply DC voltage in the case of a doubler, the device just won't work. I don't see how it will self destruct because the input current using DC voltage will simply drop to zero as the capacitors get charged. The inrush currents might be high enough to damage a diode if the capacitors are large, but this issue wouldn't go away using AC though, so I figure the designer would have to deal with that anyway. My Electrical engineering professor called AC 60Hz just DC rounded off, and in this case it would apply.
Your issue with Power factor correction is a possible problem, but usually the reactance of a switching power supply is inductive, meaning that the easiest and cheapest way to correct this is to add capacitance. Common circuits also add in mutual inductance between the two power lines, but copper costs money so this is not likely. Where it is used, DC won't upset the apple cart all that much, unless the current demands are wildly varying and the variances are happening pretty often, but most of this would be absorbed by the capacitance. I don't see a serious problem with this though in most situations.
As with any "off spec" use of things, you need to know what you are doing and understand there are risks associated with going off label. However, using DC to drive a switching power supply designed to accept AC is pretty low risk if you keep the DC voltages applied within the peak to peak voltage AC voltage on the label.
You wildly over-estimate how long it typically takes to recuss someone and how long it takes to legally confirm someone's wishes.
You assume too much.
I fully understand that the ER doctor is going to do what they do best until they KNOW (legally) that the person they are working on has other wishes. All I'm saying is that if YOU want to have a DNR order, it's up to you to communicate this wish, clearly and legally, even when you are personally unable to provide such information. A tattoo doesn't do this.
Why do you suppose we carried that binder around with my Mom? Might it be to speed up the communication of her wishes?
Sure, until you can get the paper work to the ER doctor, they will do what they will do and try to save your life best they can. At least until the Fax machine gets the necessary paperwork transferred and your wishes can be legally determined. Remember, I'm only trying to get the paperwork to the ER doctors sooner rather than later so your wishes are carried out sooner rather than later so providing information about how to get the paperwork only speeds that process along. You want a DNR order? It's your responsibility to commutate this fact, even when you can't.
When we went though this stuff with my mother who had brain cancer a few years ago, we carried a binder with her medical history and all the necessary legal paperwork to fulfill her DNR wishes any time we visited a medical facility. This binder was handed to the nurse when we checked in with an explanation of what it was and what Mom's wishes where. Of course they'd ask mom to confirm this wish when she was lucid, but having the paperwork in hand made it easier for those last days when she wasn't able to express this. In the end, if you want a DNR order, it's up to you to make sure you or your designate communicates this to your medical caregivers.
Instead of putting DNR on your chest... Why not provide the contact information of somebody who understands your medical history, your wishes, has a copy of your living will properly executed and has a valid medical power of attorney? Forget the tattoo and just go for the medical alert bracelet with the same information if you are serious.
Seems to me that a tattooed DNR request isn't likely to have the desired effect regardless of where you end up. What you need to provide access to is the actual legal paperwork and the faster you can get this into the ER doctor's hands, the better.
Wow, now that's one heck of a security feature. I'll bet somebody did this on purpose...
Did somebody's head roll over there at Apple? This should have been an obvious "feature" in the code change that should have been caught by development in a peer review of the code, should have been caught by the test team as an untested new feature, or should have been caught by the build team as an unverified change.
A bunch of folks should be reprimanded for this slipping though.. Do your jobs people!
What? You don't follow a process that creates multiple points where such a thing would be caught? Nobody can be blamed? If this is true, Apple scares me more than it used to.
Security must be both designed in and part of the process or you are wasting your time.
Yea, that wasn't a good idea was it.... Stupid is as Stupid does. Who ever did this was an idiot. Even joking about a "bomb" at the security check point will get you an all expense paid trip to the holding room and/or a brief jail stay.
Why not use something like "Free WiFi" if you insist on letting everybody on board share your service? It's bad enough you are cutting into the revenue stream of the airline by depriving them of the fees the other users of your connection would have paid, then you pile on by making a joke about having a bomb on board? Way to go....
Not only did you get your butt in trouble over the "bomb" thing, you made the airlines aware of your little sharing scheme. I'm guessing they will do something about both and send you the fuel bill for the diversion.
A wise person once told me that the most environmentally friendly building is one that's already built, at least in most instances.
Tearing down a building to put up another is horrible for the environment. All things considered it is USUALLY better for the environment to revamp and remodel an existing building over removing it and starting new.
Of course, sometimes the real issue is that the old building just looks dated or takes up too much of the buildable space and replacing it is really just an esthetics and convenience question, often justified by "we will build an environmentally friendly replacement!" statement.
Yea, but 1929 was a LOT worse because folks where losing more money than they had invested because they where buying on margins and leveraging small amounts of money to control large blocks of stock. At the end of the day, margin calls where being made and you had to make your account good. Debt was pilling up faster than anybody imagined was possible.
BitCoin investors who actually buy them can only lose their up front money should BitCoin prove worthless before they can sell them, somehow.... Nobody is going to suffer from a margin call here.
True, but 99.99% of PC power supplies built today will accept DC just fine because the first thing that happens is the AC is converted to DC in a bridge rectifier. Other designs are possible, but they are considerably more expensive to implement so they are not used. I would include Laptop supplies in the "it just works" group. In fact, *most* modern electronic equipment with an internal power supply are also likely to be fine as well, though I'd recommend at least taking a look before hooking that stuff up. One does have to watch the voltage being applied and don't exceed about 1.4X the AC input voltage or allow this to drop under about 110VDC. (So keep it under about 160 VDC for 115VAC, or 300VDC for 220VAC).
I would recommend a "test" for any expensive equipment you attach though. Put a fast blow fuse in line with the device sized to match the AC input current specified on the supply and a couple ohm resister (say about 5) to damp any inrush currents. If the fuse doesn't blow and the device powers up, you can remove the resistor (but leave the fuse in place [for safety]),
Now that does NOT mean all those wall warts will work, most of these will NOT work (and smoke will be released).
As with any rules of thumb... Your mileage may vary, proceed with caution. And I'd add that if you didn't understand everything I said above and cannot afford to replace the device, don't do this.
The Russians are not rattling their sabers claiming that they will "bomb the US out of existence" so It's going to take a lot of poking. Historically we DID poke the bear, quite a lot and managed to best the Russians in the cold war. The Russians are not crazy, they know this.
The DPRK on the other hand IS making crazy threats on the USA and it's allies in the region. So there is a BIG difference right now. Also, what about the citizens of DPRK and their plight? Are you that cold and unfeeling that you are ready to let millions of them die at the hands of a crack pot dictator who is so full of himself and his power that he would condemn his people to live in less than third world status? The problem here is Kim and his desire to keep a firm hand on the reigns of power while he beats his little pony to keep it moving.
You and I know Kim get's one nuclear shot and can do grave damage to South Korea with his conventional weapons. He's holding a hostage and making demands. How do you handle this situation? Give him what he wants?
I don't think just giving in is a prudent approach to a hostage situation, nor is giving him more hostages by allowing him to get and deploy nuclear weapons. So what are we doing? Basically, we shutoff his supplies, turned off the electricity, refused to give him anything and wait. Of course, you never know what he might do so we stand ready to defend the hostages with overwhelming force and make it clear we won't back down. It's literally Kim's move and he's running around shooting the ceilings like an idiot in an attempt to scare us.
Problem here is we don't know what Kim will do when/if he gets cornered and runs out of supplies... Will he just go out in a blaze of glory and nuke the US? Will he give up, cry uncle and start cooperating? Or, (my personal bet) will he be put down from within? One of those options makes a bomb shelter a good investment..
Back with the Prius first came out, I read a story about how the battery voltage (somewhere between 100 and 200V DC) could easily drive almost any computer power supply DIRECTLY, no modifications required. This guy figured out that he could run his whole Ham Radio station and computers using his 2nd hand Prius as a source of backup power. Said it had a really nice battery capacity and you could just let the motor run to charge it now and then. I don't suppose a Tesla would be much different, except you won't have the backup generator part.

In fact.. Don't mine at all because it may be profitable based on the electricity used, but you will be hard pressed to pay for the hardware.
What? You don't take BitCoin? Shame on you!

Hey, if you are day trading, a week ago doesn't mater. It's ancient history.
