HackMeSomeUnicoins.md

Just go to stackoverflow.com then define this in your Javascript console:

(function(myFkey) {
  console.log("Ok, let's hack you some shiny unicoins! <3 /dev/alias (www.devalias.net)")
  console.log("The powers that be say you can only mine a rock every 10sec, so we do it every 11sec to be sure.")
  window.setInterval(function(){
    $.get( "http://stackoverflow.com/unicoin/rock", function( data ) {
      var rockId = data.rock;
      $.post( "http://stackoverflow.com/unicoin/mine?rock=" + rockId, { fkey: myFkey })
      .done(function( data ) {
        var bal = $('.uc-balance');
        bal.text(parseInt(bal.text())+data.value);
        console.log(data);
      });
    });
  }, 11000);
})(StackExchange.options.user.fkey);

(Thanks to @ouranos for the fkey options string)

You can get your fkey by inspecting the POST made when you successfully (manually) mine a rock. (It's also stored in a data-fkey type value somewhere, but haven't been bothered to find it and automagically pull it out (feel free to contribute some JS to do it)

Just updated to be easier to copy and paste, as well as update the count on the sidebar.
