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?"
Ok it sounds paranoid but on several occasions I've met up with someone from the internet.
I usually have a few details about them but given I'm into the alternative scene (and I don't mean music) you don't usually just pass these details to a friend.
Never the less, meeting up with someone like this for these kind of activities is down right dangerous, taking a few precautions is always sensible.
I usually put together a zip file filled with every piece of contact information I have for this person and use a cron job to email this in 48 hours if I dont stop it.
I also send a text message to myself prior to entering anyones house that I am meeting like this - the uk mobile phone companies will store location information for up to 3 years.
Ok its paranoid but I know several people (though usually women) that have been raped meeting like this - worse things could possibly happen as you are taking your life in your hands doing though. I'll admit that being a guy I am probably less vulnrable - but its better to be on the safe side and atleast give yourself some backup.
Its never gone off before... but its nice to know its set up - just in case.
About six years ago I had the misfortune of working for a company where our lead developer was a complete fruitcake. He wore all black every day, put his cigarettes out on his keyboard, you name it. He was one of those die-hard, born-in-the-soup hackers who started out configuring the household appliances to kill his family.
A genuine genius, and impossible to work with.
Well, one week he had happened to catch some variant on the face-melting death. I'm talking about the kind of influenza which turns your various facial orifices into creeping faucets of mucus. His wife assured me of a fever which would kill a lesser being. Sweat sheeted off his face like a rainstorm on a greenhouse roof. Needless to say he took some time off.
I get a call on Friday afternoon and it's him. The sounds coming from his end of the call were like the elephant throwing up and trying to talk into the little voice scrambling doohickey from the movie Scream. "You have to come get me," he says. "Why?" I reply. "Because I'm in no shape to drive, and I need to login to my computer there." Empathetically, I told him to stay there if he was sick. "You don't understand," he barfed, "If I don't login once a week..."
Yes. He had a DMS on our key development machines. One which he explained would lock up everything tighter than [gratuitous image deleted].
I was unthrilled to say the least, and refrained from chewing him out as he brought his barely clothed mass of plague into my beautiful car, coughed plumes of virii and bacteria into our office, made my boss practically bust a vein in his forehead as I led his nearly-blind ass to his computer-- all because he refused to share his password with us to access and protect company property --then finally have the nerve to croak a child-like plea for McDonald's from my back seat on the way home.
Once he was fully recovered we had the intervention and asked the usual questions, Why do you think this is necessary? What are you hiding from us? How screwed would we actually be if he actually died? Etc. In his paranoid, seen-the-Matrix-too-many-times universe, there was nothing wrong with installing some 'basic security'.
I did mention this guy was a genius, right?
The boss caved completely, and to be honest, we all knew there was no way in heck we could find whatever weird little bombs he'd hidden in our own system let alone the machine he'd practically joined to at the spine 12 hours a day. I quit the company that June, Mr. Maniac is still writing all their code and the company is quite successful.
So, yeah, DMS... Why send email to the unworthy after you're claimed in the Lord's rapture, when you can just grab your entire company by the nuts and twist?
