Unicorn "Miner" CodeGolf This is a pretty cool CodeGolf challenge in the sense that you're only going to have a limited amount of time to do it. You need to build a program that "mines" StackOverflow unicoins. In order to do this, you need to perform just two HTTP requests. I'm not going to say how, to add to the fun.

The first person to do this gets a -10 on their score. Good luck! Also, if your doing this in JavaScript or similar, you don't need to account for the target browser's XSS, etc. prevention.
Javascript, 104 (114 chars - 10 bonus)
All due credit here.  Simply posting this to get the &quot;first answer&quot; -10 bonus ;-).
p='$.post(&quot;/unicoin/'
setInterval(p+'rock&quot;,function(o){'+p+'mine?rock=&quot;+o.rock,StackExchange.options.user)})',2e4)

setInterval accepts both functions and strings of code. After susbtituting the variable p, the following gets executed every 20 seconds:
$.post(&quot;/unicoin/rock&quot;, function(o) {
    $.post(&quot;/unicoin/mine?rock=&quot; + o.rock, StackExchange.options.user)
} 


Edits are welcome.  I don't know javascript well enough to really competitively golf this.
