BigO = Performance! And other lies programmers tell themselves!!

Have you ever analyzed your algorithm and found out that it runs in O(n^2) and thought to yourself, "man I'm a crappy programmer...". Well, you are! But not for the reasons you think! If you think Big Oh = performance, boy have I got news for you. In this video I try to dispel this fallacy that programmers have assumed, that Big Oh complexity equates to performance.

Yea, there's probably issues with the way I timed this and stuff. I don't really care. It's simply to illustrate a point, which is this is all utterly worthless and I wasted my time to try to illustrate that Big Oh complexity means absolutely nothing in terms of profiling your code.
