What Does Your Dead Man's Switch Do?

LqdEngineer asks: "How many of you use or have used a Dead Man's Switch designed to perform some action if you don't check in for a certain amount of time? Recently, I decided to put one together using MySQL and some cron jobs, but I wanted to see what others have their switches set up to do in the event you fail to check in. E-mails to loved ones? Send encryption keys to friends/family? Hate mail to your boss? Has anyone ever been on the receiving end of the results of such a system?"

    I've always thought that a Dead Man's Switch held too many problems. Unless you have people that are 'out to get you' and your switch is your leverage, then it's not much use.

    What happens if you get into a severe accident and end up in the hospital without the ability to 'check in' with it? What happens if you are stranded at an airport with a snowstorm? What if you are stranded at a ski lodge in the mountains in the middle of a snow storm? etc...

    If you were ever unable to check in with the switch, then you would probably regret hate mail to your boss or other nasties that you had planned to send to people you hate. It would also be an unwelcome surprise for friends and family to get 'letters from the dead' just to find out that you really aren't dead. It would definitely be a detriment to you if you had it setup to donate all of the money in your bank accounts to charities....

    The Dead Man's Switch has too many if's in it. It makes more sense to just put together a will and make sure you entrust someone you deeply trust to execute it.

      Well ..... considering that whatever is encrypted behind those keys might conceivably be enough to send you to jail anyway (and possibly for a longer term), it might be worth swallowing the lighter sentence for not handing over your keys.

    When you're gone, you're gone. The world is meaningless, because you no longer exist.

    No matter how inflated our egos, after a few tears and a small feast for the worms, the planet will continue as if we never even happened. Why complicate matters with a dead man's switch?

    What a sadly egoist world view you have.

    World may be meaningless to you. You are dead. You, in effect, do not exist anymore. But the world does not stop existing simply because you expire.
    You are not the center of the universe. You are merely an almost infinitesimal part of the big, grand, large, larger than life universe.

    Children are naturally egoist. You are 22. What is your excuse? :)

  5. I've got one. by munpfazy · · Score: 4, Insightful

    I often take part in political protests, and have on occasion been arrested and held for days.

    So, I put together a quick routine using perl and chron that dispatches email to my workplace, the local legal rep contact, and some friends. The later includes directions to a hidden key and asks them to feed my cat until they hear from me. I only enable the system when I'm expecting a significant risk of arrest. Once it's started, if I don't either log into the machine or send myself an email containing a specific string once every 24 hours, the alarm goes off.

    Turns out it's never actually been used (except when testing.) I did get caught up in a surprise arrest not too long ago, but since my girlfriend was going to be at home and able to take care of any problems I didn't turn on the system.

    But, if you ask me, trusting life-changing information to a php script is a really, really scary idea. Even my trivial "please feed my cat" letters included disclaimers explaining that they may have been falsely triggered.

    Now, on the other hand, the possibility of spoofing dead man's letters from other people *does* sound promising.

    Whatever these little consequences are, they can't concern me anymore, since i'm already dead...This thinking can, of course, lead to amoral decisions, and that's why we have invented religion :)

    The fact that consequences of your death can't concern you when you're dead, in no way means that reasonably foreseeable post-mortem consequences should not concern you now.

    That's why even people who don't believe in any sort of "afterlife" still buy life insurance to take care of their kids.

    You don't need any sort of supernatural belief to end up with behavior that most people would call "moral", just some compassion and a reasonable ability to foresee the consequences of your actions.

    Which takes me off on a bit of a tangent...

    Foreseeing the effects of our actions is of obvious use; if you can't do that to at least some degree, you'll quickly end up dead or institutionalized.

    But compassion? What's in it for me, you wonder.

    Cultivating compassion expands the self. We're pretty darn sure that the human body known as "Lukas Beeler" is eventually going to stop functioning and in some way dissolve (rot in the ground, be burned up, eaten by squirrels, whatever). If you completely identify "yourself" as "Lukas Beeler", well, then, that's it for you. Maybe you can tickle the pleasure centers of that lump of meat a little bit before it dissolves, but that seems an unsatisfactory goal.

    But is identifying "yourself" as "Lukas Beeler" the only option? Throughout history, some people - people who seem to derive a great deal more contentment from life than the average Joe - have suggested that transpersonalization provides a more satisfactory experience. This means identifying "yourself" as more than "Lukas Beeler".

    By "more than", I do not mean anything supernatural, I am not speaking of a "soul" or anything metaphysical like that. But what if, for example, you were to invest a portion of your own concept of identity into your family? Unless all your relatives are childless, your family will outlast your body, so that "you" might have a larger and longer existence than the body of "Lukas Beeler".

    What if you were to invest your identity into your community, your city or your nation? That's an even larger and longer existence. Perhaps we have here a sensible argument for patriotism. But why stop there, when by identifying "yourself" with the whole human race, "you" get even bigger and longer-lived?

    Now, hold on there, you ask. How in world am I supposed to accomplish this "investment of identity" that you're going on about? Well, it means to think of yourself as these other people. It's an exercise of imagination, to see things through their eyes, to feel what they feel. With that exercise, eventually it can be seen that the ordinary idea of "self" is just a mental construct, just an idea, not an immutable reality.

    In other words, compassion is the tool and the method to get You out of you, the "big You" of consciousness out of the "small you" of flesh.

    Indeed, if you get good at it, you may find that you can see "yourself" not just in other humans, but in other animals; in the trees; in the whole biosphere. Expanding "yourself" until not much identity is left connected with the body known as "Lukas Beeler".

    And maybe you can keep going. Eventually you might find yourself worrying about the heat death of the observable Universe, billions of years in the future, as your end, instead of the dissolution of "Lukas Beeler" in a few decades. That's a pretty massive trade-up. And if you get that far, it's comforting to consider that cosmology seems more and more to be considering some sort of "multi-verse" scheme in which our observable Universe is only a part; there's still more to become.

    "A human being is a part of a whole, called by us 'universe', a part limited in time and space. He experiences himself, his thoughts and feelings as something separated from the re
