Nice. I love these posts so much I keep a collection of them.

For this though “one of the easiest ways to make a program faster is to make it do less work”. Correct me if I am wrong but isn’t that the only way to make programs faster? Do less work on a single core is the only method I have ever seen. Everything, from memory alignment to SIMD is just reducing the amount of steps. Would be happy to know an exception to this.
