The One Billion Row Challenge in Go: from 1m45s to 3.4s in nine solutions a great write up by Ben with lots of details about the Go implementation. It’s always fun to optimize something to the point where it does not really make any sense anymore as long as you do not have to ship it.

The two domains in which I have seen the most absurd things are embedded systems and high frequency trading. Both domains I am not involved with for a long time, so something like this hits the spot :)

The Java implementation linked in the article is also worth checking out.
