I always refuse to take the nuclear power protestors seriously until they agree to go out and pull their electric meters and refuse to do any business with anybody who uses electricity both directly and indirectly.
So far, I've not found anybody I can take seriously....
I didn't say it was an impossible problem to solve, only that Un has caused his people unnecessary work for the express purpose of thumbing his nose at Japan... Some OS vendors may provide the necessary changes, others may not care. Certainly any embedded devices won't likely see firmware updates any time soon.
Really, it doesn't matter what Un does or which time zone he creates... It's all for DPRK PR purposes and nothing more. He had to do *something* about the 70th anniversary of some big event to mark it and if this is all he can manage, he really is impotent in all the world beyond his country's borders.
Yea, just don't try to connect up to a NTP server or build a strat 1 server from a GPS receiver when you fudge the hardware clock... You are going to be on your own. And that's going to make things like navigation and advancing technology all that much harder there.
Little'Un just made life harder for his people by doing this, but he doesn't care. Folks have to remember ONE very important fact. Little'Un does what he does for consumption INSIDE of North Korea and that's it. The world will deride him for doing stupid things, but what matters is how the North Korean's perceive it. You can bet they all praise "Dear Leader" for his strong defiance of the Imperialist Japan and most will actually believe what they are saying. Few will realize that he's really showing his impotence, his lack of power and how the rest of the world is making fun of him and the ones that DO realize this won't say anything different because they know it means death for them and their extended families.
So while we laugh because we find it funny, in reality this is really very sad for the people it most concerns..
Any processor, much less Xenons, in Epoxy is going to get hot. Like, the epoxy is going to melt hot.
Even without the epoxy, that's a huge power profile in a small space. How exactly are they going to cool that?
That's true... But it's not the car being broke, but your ability to refuel it being broke.
Gasoline cars will suffer from the same "how can I refuel it" problem. Without power, the local gas station won't be working for you either... I suppose you could manually pump gasoline out of the ground, or have fuel in storage, but if you are a real preper type, you've thought of all that..
Koreans, even North Koreans, have very legitimate historical reasons to tell Japan to FUCK OFF.
That is true, but how does THIS have anything to do with what Japan did to them before WW2? How's it harm Japan if NK want's to change their wristwatches? Yea, I'm sure that has half of Tokyo shaking in their boots....
This is not much more than symbolic, but NK has been reduced to making symbolic gestures for decades. (Hey, isn't that little'Un with is middle finger in the air again?) I'm laughing over here in North America, and I'm sure about all that's shaking in Japan is heads..
Keep trying to poke the world in the eye with your little stick..
Seriously? Who cares? It just means that all the computers in North Korea won't show the right time until somebody decides to update the operating system..
You don't get out of jail free by using diesel. Modern diesel engines on the road today are cuck full of electronic controls used to meet the EPA's standards.
To protect against nuclear EMP (since we were talking Fallout)? Not so much.
Trust me on this... EMP is NOT an issue for your automobile... They tested this with a number of vehicles years ago and found that EMP was not a major issue for the electronics in cars.
EMP affects electronics to varying degrees. I break it down into three groups. First there is the "no noticeable" affect group. This is where an EMP has no noticeable affect on the equipment's operation, for a car this means it keeps running. Second there is the "upset" where the EMP causes the equipment to malfunction temporally. Then there is the "Requires repair" category where the EMP breaks something so the system doesn't operate.
As I recall, they tested a dozen vehicles, ranging from small cars to large trucks and they applied pulses at the strength one expects to see just outside the blast radius of your standard nuclear device where one would expect that people could drive. ALL of the vehicles fell in the first two categories, with most falling in the first. It was like 2 out of 12 vehicles that where upset enough to stop running, and both of these where "repaired" by turning off the key and restarting them.
I conclude from this that EMP isn't a problem for the vast majority of vehicles on the road today. If you think about this, it makes perfect sense. Electronics in cars are basically inside of a metal box, which is itself inside of metal boxes. They are self contained electrical systems in a faraday cage, especially the parts that "make it run" down the road.
So don't worry your self over your modern car not running in the event of an EMP.... There will be MUCH bigger fish to fry if that happens. You are going to need water, food and protection first, not transportation.
Some day there will be a market for a car with no on board computer or electronics.
Not going to happen, both the EPA and the CAFE standards have seen to that. There is ZERO chance you can meet the emission and mileage standards for any vehicle which doesn't include some kind of engine and drive train control electronics.
Unless, of course, you are talking about a future time w/o the Federal Government being around... In which case, buying cars will be the least of your worries...
I am not as convinced with the theory I put forth now, but it did force me to take a look at what happened closer.
Actually, there are two major problems with this theory of mine... 1 is what you point out and 2 is that the aircraft actually flies a completely different route than I had thought. Yes, it does look like the aircraft returned to Malaysia as I suggested, but then it turns right and flies north west and doesn't change to a southern route until after it passes out of RADAR coverage. This implies that somebody did some fairly involved flying, or spent some time programming the flight director at some point.
However, the fire theory does have some merit. There was a pallet of LiIon batteries in the forward hold which could have easily disabled the radios in the forward avionics bay, or had the pilots turning off stuff fairly quickly, and even in commercial flying you'd be turning off the radios when dealing with a fire of unknown origin. And I'd like to point out that "Establish Crew Communication" means that the two pilots and possibly the flight attendants are talking, not that you can talk to ATC.
Further, they are out over open water being handed off from one country's controllers to another. There is no huge hurry to check in and if something starts to come apart, like you smell smoke just as you are hitting the swap button on the coms to bring up the next frequency it is conceivable that they actually tried to communicate, but where unsuccessful.
But it does seem clear that nobody was able to do anything to control the aircraft for a LONG time before it crashed. That as it flew south into the Indian Ocean everybody on board was likely incapacitated. That looks like a loss of cabin pressurization, and the question then becomes why did it happen? Did somebody make it happen or was it an accident? Was this a secondary result of a fire?
It's anybody's guess, until we find the aircraft, look at it and winnow down the possibilities. Lord I hope they are looking in the right place though..
A vacuum has less atoms there to create the ionized gas to make a plasma trail. It also has a higher breakdown voltage and should you get an arc, more resistance. Other gasses are sometimes used because they are harder to ionize either do to the valiance electrons being tightly bound in filled orbits or tightly held by chemical bonds. That is why they use the noble gasses for this kind of thing, they are very unreactive with the top level electron orbits being full.
For automobile manufacturers to start factoring in the time of day and keeping the "key" hidden...
It works this way... You have an pre-shared key and you encrypt an ever changing sequence of messages, say something related to the current time of day or the "rolling code" thing they use now only the code rolls over time not when it's used. Then the "code" that worked 5 seconds ago, won't work in the future. That ends the "record and playback" messages from being seen as valid and all you need to have is a reasonably accurate scheme to advance time on both the car and the key fob. I imagine that regular resyncing of the clocks might be necessary, but I'm sure we can work something out where you "program" your key fob by inserting it into a port on your car or by using some RF backscatter power process the fob and the car can get into sync.
It doesn't stop brute force attacks to recover the key, but it does make it time consuming and unlikely to be accomplished by some thief walking though the parking lot.
Google may indeed be engineering their own systems, but THEY don't build them, they have that done. They also don't build the components that go into the systems, they buy this stuff already made. Further they don't go out and produce the raw materials that go into the components that they are stuffing into the custom designed motherboards....
But that doesn't change what I'm saying... There is a specific cost involved in setting up a data center. Then it costs you money to operate the thing, plus it costs you to get rid of it. All these costs must be less than what you can make running the data center or the whole thing is not worth considering as a business... But even more, you must have a cash flow structure that allows you to pay the bills as they come in as well, which is where MOST businesses started by non-business folks fail...
It's a total lifecycle cost and cash flow question and if you don't have a plan that gets you a profit and cash flow necessary it doesn't matter. PUE and WEE have zero bearing on cash flow or profit and as I've been arguing, have nothing to do with the business side of a datacenter...
Just remove the TCP stack.
If you have physical access to the machine however, that's a different story.
Unplug the Monitor and remove the keyboard too?
Oh heck, just totally disassemble the computer and disconnect all the cables, store it in a EM and physically sealed container which is buried under a few feet of reinforced concrete....
No computer is unhackable, especially one that is turned on and connected to ANYTHING else.
So, if it's unknowable with any certainty you want to just ignore the costs? That's not a good idea..
You simply have to at least think about decommissioning costs, if you are going to be responsible in your business plan. Sure, you can ignore these costs and just plan to go bankrupt and let your creditors and share holders clean up the mess but I don't feel that is ethical and just going out of business is generally not the desired situation.
You keep dropping into the supply chain and talking about raw materials. That is totally irrelevant to the business we are discussing, unless you are suggesting that the business you are in is doing all of these things. If you are going to buy your servers from Dell or HP, all you need to know is how much the servers will cost you to buy, maintain, and get rid of when they are useless someday.
This is crap and it won't work for practical power generation, TRUST me on this, I'm an electrical engineer.
BTW... Power is the issue here. Voltage is but ONE part of how you get power. You can have a thousand volts, but if it can only supply a few micro amps, you don't have much power.
So you are waving around a big coil of ware and measuring a voltage across it.. Big deal, the question is HOW MUCH POWER are you getting? 37 volts is NOT a measure of power, but Electro Motive Force. You need CURRENT to go with that 37 volts, or this whole exercise is pointless.
For the LED experiment you describe, I don't doubt you can get 60 cycle power by placing a long wire along a power transmission line. (50 Cycles in Europe) But that's not "free" energy from the sun. In engineering school one of the home work problems we did was EXACTLY about this. We where asked to calculate how much wire it would take to get 100W off of that standard power transmission line. Using both magnetic and electric fields, the amount of wire was HUGE and when you added in I^2R losses of copper to find the gage you needed it became very expensive indeed.
So, remember what this ol' engineer told you.. Interesting experiment, but very much not practical on any scale that is useful.

I agree, the solution you suggest would be MUCH safer, but as you point out, this makes the fob a whole lot more complex (and power hungry).
In fact both of the suggested solutions are not new concepts, but have been used in networks for years.
