    It might only have to access it and that can be done through the OS now. It might be possible to piggyback on that, no?

    No, actually, not really. There are registers that, after a certain point of the bring-up process for the silicon, are locked out from access in production parts. In testing the boot process is halted at a certain point in order to 'unlock' parts and allow access to various registers. Once an OS is booted, it's no longer possible to access some of those registers.

    It's true. It's incredibly expensive to scrap silicon once it's been cut from the wafer, attached to the package, and tested. They'll fuse them differently and mark them differently and sell them. The consequence of just shit-canning everything but the cream-of-the-crop parts would be you'd pay $1000 for a CPU (or some such relatively astronomical figure). Also, there is such a thing as 'margining', where silicon is tested beyond the design parameters, but not 'officially' rated for operation outside those parameters, to ensure reliable operation if the silicon is in some circumstances pushed to extremes.

    I wonder if a rootkit could make the motherboard burn up the CPU? Poof! La computer muerte.

    Depends on how the power delivery on the motherboard is designed, really. You'd have to be able to turn up the supply rails well beyond the margin the silicon is designed and tested for, and I don't think any competent manufacturer would design SMBus-accessible on-board switching regulators to do that; plus tune relevant PLLs for a higher output frequency, plus turn off the CPU cooling fan, plus disable all thermal management that would otherwise shut everything down. Much of this would have to be done at system power-on before everything gets locked down. You'd probably have to infect the BIOS itself, and aren't they all signed now to prevent such a thing from happening?

    I should have been more descriptive. What I meant was how a twisted-pair cable cancels out common-mode noise, and how a differential pair also doesn't radiate much, because the magnetic fields are 180 degrees out of phase, so they cancel. Is that a fair approximation of what's going on here, the magnetic field that the plasma is generating is cancelling itself out because it's twisted?

    I dunno about 'secessionism' being a basic right of all sentient beings, but 'civil disobedience' sure as hell is, or should be; life (the continuance of, and quality of, that is) more important than government, or even laws; those two things are supposed to facilitate life, not the other way around. When they get transposed, then Bad Things are happening; the system is broken and must be 'fixed' -- thus 'civil disobedience'. As someone else once said, 'Soap box, ballot box, and ammo box -- use them in that order'. 'Secession' should the be last resort. If your system of government doesn't allow the first two, and you have to immediately go to the third and last option, then you've got a poorly designed system of government.

    You, apparently, have never considered what it's like for someone who has been in an accident caused by someone with no auto insurance. They walk away from the whole thing more or less scot-free, and you're left with no working vehicle (that you may still be making payments on) and maybe no way to afford repairing it anytime soon (or replacing it if it's totalled). Meanwhile the jerk with no insurance, who more likely than not has no money and no regular income (or at least so little income that there's not much to take from them in court) shrugs and tells you 'tough luck'. That's a valid use for insurance, as much as we hate paying it. Note that I am not saying insurance companies are all or always fair when you make a claim, I personally know better than that. But at least if the jerk that hits you has insurance you have a chance of getting your vehicle repaired.

    Making guns more difficult to obtain isn't going to solve a single violence problem in the U.S. People who want to commit acts of violence will find a way to get the weapons they want to use to commit that violence, and if they can't get guns, they'll find some other way.

Gasoline and a few other things can be used to make very messy bombs. Knives, swords, machetes from Harbor Freight Tools.. the list goes on. Making guns harder and harder to get or banning gun ownership won't do a damn thing, and I have nothing but contempt for people who are using recent tragedies as a springboard for their anti-gun agendas.

    Can you 'fake it' at home with makeshift equipment? Yes, sort of. The problem is when you assemble your board, and you find it doesn't work. You can't check the solder connections on a BGA device unless you've got an Xray machine to do that. What you're faced with then, is trying to get the BGA packaged device back off the PCB without destroying the PCB, throwing the device away, and trying again with a new device -- and you're back where you started from, hoping all the balls made contact and reflowed properly so your board works. If the device(s) in question are expensive then, well, it can get expensive quick. If there are multiple BGA's in your design, you may very well not have any way to troubleshoot it and determine which device didn't reflow properly. Your other option would be to see if an assembly house would do the job for you -- and I've never tried arranging that, but I think, knowing what I know of this, it would be expensive. So can you do it? Yes. Can you do it successfully? It's a coin-flip.

    Pretty much, yeah. The prevalence of large devices in BGA packages has also more or less destroyed any ability to repair anything; most of it may as well be sealed in a block of opaque epoxy for all the good it'll do you. Even you have the thousands of dollars of equipment necessary to deal with BGA packaged devices, you can't easily salvage and re-use anything; even if you can re-ball them, they might not survive the entire process. Thankfully there is still quite a bit of SM devices that you can hand-solder, or at least deal with without having to have $10000 worth of equipment to work with, and if your design can be 100% SMD, creating a PCB with home equipment is actually easier since you don't need to worry so much about drilling holes and plating them through (except for vias, if you need them). If you're brave and resourceful small BGA devices could be IR reflowed, with of course a chance of failure.
