IS THE LEAKED HDCP MASTER KEY REAL? Discuss your thoughts here
HDCP MASTER KEY (MIRROR THIS TEXT!)
This is a forty times forty element matrix of fifty-six bit
hexadecimal numbers.
To generate a source key, take a forty-bit number that (in
binary) consists of twenty ones and twenty zeroes; this is
the source KSV. Add together those twenty rows of the matrix
that correspond to the ones in the KSV (with the lowest bit
in the KSV corresponding to the first row), taking all elements

Is this partial application? Currying? Something else? Vindaloo maybe?
// See my blog post:
// http://benalman.com/news/2010/09/partial-application-in-javascript/
// In the following code sample, invoking the curried function will always
// return a function until all arguments are satisfied, at which point the
// original function is invoked, returning its result. This means that all
// function arguments are required, which also allows the function to be
// called either like foo( 1, 2, 3 ) or foo( 1 )( 2 )( 3 ). This also means
// that if any argument is omitted, the original function is never invoked.
