    When hit with one yes... But the voltage is just 12V (or maybe 24V for a large one).
    That won't do much unless you find some way to lower your resistance a lot (like the darwin award mentioned above). What is dangerous is that a car battery can sustain a large current for a long time.
    (A quick shock to the hart is not as bad as keeping it from beating for several seconds). But you still need the low resistance to actually let it flow.

    Arp still is only used in a single subnet at a time.
    Likewise your MAC address was only in use (and only usefull) in a single subnet at a time (asuming you weren't bridging 150 networks at the SAME time)
    If I had your MAC would I have been able to trace you to any of the 150+ ip addresses or do anything without happening to be in the same subnet you were at that time?

    A merry go round is a very bad example for orbital mechanics....

    By moving the center of gravity of the elevator around the geosynchronous orbit you can slingshot yourself pretty much to any orbit you want using the pivot point on earth as a lever.
    You would need some energy to move the mass around though... (For instance using solar panels on the counterweight to move a small piece of it to a higher or lower orbit along the cable) This energy makes up for the energy you loose by letting the stuff that goes up go.

    Its not a problem at all and would be negligable in comparison to the corrections you would have to do anyway to keep the thing in the right spot.

    And that is the trick:
    You have a big counterweight in geosynchronous orbit. The mass you launch is significantly smaller.
    Once it gets up there it is also in a geosynchronous orbit and you simply let go of it and it will stay in orbit.

    The call to your own fixed phone from anywhere in the world is totally unrelated to what I was talking about.
    Also the mobile being reachable is not the same since the call will still be routed through your telcos system. (Your number still points and always has pointed to your operator, they just reroute it to your phone over a different system but the number still ends up pointing to them)

    A sim is not like a mac address, since mac addresses generally don't travel beyond one subnet so your analogy is even worse.
    If I know your ip number I have a pointer to some place on the internet, if I have your mac address I don't have shit (except who made your nic).

    If I know your telephone number I have a pointer to some telcos network. I know in which country the central is where calls for this number are handled.

    Funny, you are arguing against yourself:

    With 'NO' you imply that me tripping the power cord wasn't a software bug....
    Now lets have some fun with the rest of your post:

    I'm saying it's a software bug when your code goes blank and stops when it was supposed to make sense and execute.

    If the programmer explicitly blanked the RAM it's a bug in the software due to the fault of the programmer. If the user randomly pulls the plug, it's a bug in the software due to the fault of the user.

    Just because the user caused the bug in the software to appear doesn't mean it's not a software bug. Users aren't any less capable of adding bugs to software than an incompetent programmer is.
