    Did you miss the part were peering with Netflix relieves their transit requirements? If it is less expensive to peer with Netflix (and/or host their caching appliances) than to pay for the transit required to support them, why wouldn't this make sense?

    Free peering with Netflix assuming that they meet the requirements other than traffic parity has the advantage of removing their traffic from the ISP's expensive transit links.

    Most of the grid-tie inverters I have seen do not support a stand alone operating mode; they *must* be connected to the grid to operate. The exceptions are the ones which also support batteries for independent operation when the grid power fails.

  8. For a given density, the satellite's cross sectional area (and drag) are proportional to the square of the linear size but the mass is proportional to the cube of the linear size so drag has a smaller effect on larger satellites.

    The major difference between physical and software was that she was without her car for 10 weeks while they waited for parts, vs a quick trip for a software update.

    Removing the battery would allow the alternator to power the car by itself. Without the battery to smooth out the dirty alternator power, chances are the ECU and any other delicate electronics could be damaged. And with how much a serpentine belt connects to nowadays I wouldn't even begin to consider changing one (thus disconnecting the alternator) while the engine is running. It would be a great way to lose a hand.

    Yep. The battery filters the output from the alternator and is required for proper operation. Removing it alters the frequency compensation and may result in catastrophic failure. It is possible to design the charging loop to work without the battery but how likely is that?

    I would not even mess with a V-belt while the engine is operating.

    What *would* work although it is hard on the alternator is to disconnect just the alternator charging connection on the battery side. Then disconnect the battery.

    The easiest and safest way would be the pull the relay for the fuel pump, or, if that's too hard to find, start smacking the rear sides of the vehicle until the cutoff activates. Also possible, though a bit harder, would be to choke out the engine by opening the intake and placing a plate over the opening. If it were a modern gas vehicle you could also unplug the coils.

    These are good alternatives. If the fuel from the pump goes through a rubber gas line, that could be pinched with some vice grips.

    I have used Compact Flash to IDE adapters to replace old hard drives however apparently I have also been lucking in my choice of Compact Flash cards; like almost all Flash storage except for some SSDs, most are terribly unreliable.

    In short, there is no reliability issue, and the write limitation is a non issue for 99.999% of the computers out there. It just doesn't seem to be working for *you*

    SSD reliability issues include in rough order of importance:

    1. Corruption on Power Loss
    2. Trim Corruption
    3. Unpowered Retention
    4. Write Endurance

    The problems with trim are annoying but no SSD should need to use trim for good performance. Those that do were designed poorly:

    Corruption on power loss in this case is not corruption of data being written at the time of power loss; that is expected. It is corruption of unrelated data or state which may render the drive unusable. Some SSDs do not suffer from this problem and it should not occur in a portable application because of battery operation but a desktop is different matter.

    The mercury switches were a source of mercury not a source of switches. The presence of chemicals suggest the possibility of making mercury fulminate which is a friction and pressure sensitive explosive that can be used to trigger larger explosive charges.

    This is why I use silver fulminate for my initiators. Buying silver does not bring the same attention as scavenging or buying mercury does.

    The other thing that really fucked up state's rights was the change to the senate. The senate used to be elected by the states themselves. Thus the house was a democratic body where people would vote on the basis of population and the states themselves had to approve things for it to become law.

    Now the senate is basically the same as the house.

    I agree but before the 17th Amendment, a majority of the States were already directly electing their Senators to Congress so this was a state by state change.

    It would be but the official PoE standards, 802.3af or 802.3at, are not trivial to implement and consumer PoE ports are not common so it would be a wasted capability which just raises the cost for most consumers. If they used simpler passive PoE, then it would result in more support costs.

    I guess SSD warranties now need a clause about not being unused for too long. In fact, I wouldn't expect a HD to stay fully functional after 10 years of shelf time.

    I would. I have powered up hard drives after 10 years and they retained their contents just fine but of course those hard drives were at least 10 year old designs. I have yet to power up any high density Flash device after 1 year and have it fully retain its contents.

    Well, I sort of figured this out, and hence wanted to point out that the terminology does not make sense. "Triple Level" does not sound like three bits or eight levels.

    This is marketing at work; it does not have to make technical sense. MLC is an acronym for multi level cell and commonly means 2 bits or 4 levels. TLC is an acronym for triple level cell and means 3 bits or 8 levels. This is why marketing gets the big bucks and engineering gets layoffs; if you are not sales, then you are overhead.

    And what is the unpowered retention time of those inexpensive Flash memory sticks? All of the USB Flash drives I have tested had an unpowered (and powered) retention time of less than a year when new which makes them suitable for only short term storage.
