 +> Given an ASCII string X, take the len(X) most significant bits of the md5 hash digest of that string. Treat those bits as an unsigned int, and append its base16 representation to "http://swiftstack.com/". Do it for "pycon2013."
 +
 +Hmm, something like this works:
 +
 +<code>
 +>>> s = "pycon2013"
 +>>> hex( int( bin( int( hashlib.md5( s ).hexdigest(), 16 ) )[2:len(s)+2], 2 ) )[2:]
