Nice "initiation" article/post about "Perceptual Hashing".
Its continuation (of sorts) it's also a worthy read (2nd jump).

But Adleman wanted to tackle the question from the opposite direction. What if life itself, already susceptible to genetic engineering, could be used to solve problems? What if DNA could be shifted from reproducing life to thinking about it?

Directly from the author's pen:
I have been intending to write this essay for months. Why am I finally doing it? Because I finally found some uncommitted time? Wrong. I have papers to grade, textbook orders to fill out, an NSF proposal to referee, dissertation drafts to read. I am working on this essay as a way of not doing all of those things.
