There's ways to amuse yourself while doing things and thats how I look at efficency.
It would be nice if we could design a virtual reality in Hyperbolic Space, and meet each other there.
Beware of bugs in the above code; I have only proved it correct, not tried it.
We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Yet we should not pass up our opportunities in that critical 3%
An algorithm must be seen to be believed.
If you optimize everything, you will always be unhappy.
