Integral of (1-cos(x))/x^2 from 0 to infinity

In this neat video, I calculate the integral from 0 to infinity of 1-cos(x)/x^2 using complex analysis. For this I choose a very clever contour that jumps over the singularity at 0. This problem is taken from the book Complex analysis by Stein and Shakarchi
