So someone was able to construct a hard drive in mine craft, good.
For someone to have a working hard-drive of capacity N, the game itself needs to be running on a computer which has a hard drive of capacity N+1, the +1 is for storing the actual game itself.
We can similarly say to have a working cpu of capacity N, the game itself needs to be running on a computer which has a cpu capacity of N+1, the +1 for actually running the game itself.
If we were to assume that we live in a virtual world, then in order for us to create new artificial life inside of our virtual world, we would first need to construct a computer that is at-least as big as the computer we are already in.
Can you simulate a computer that is bigger and faster than the computer on which the simulation is running ? I would say no, hence we can never simulate artificial life in its truest form.
I am sure we can and will create artificial life but will it ever match what we ourselves live in ? I don’t think that so.
Wow, I did not know about it till last week and when I read about it, I was like where has this been all my life :-)
Anyways its called Pairing Functions, which allows you to reduce 2 positive numbers into 1 and back.
Uses: Imagine you had a set of objects called Pair(long,long) and you wanted to search if a particular pair exists in that set, the usual way would be implement hashcode and equals . But with a pairing function you can reduce it to a set of longs.
In my experiments I saw an improvement of 30-40%.
