I was just going to post that. I don't think any other explanation or tutorial does a more complete-yet-understandable job of explaining how the DFT actually works. I feel like there are a million articles out there that do basically what this article does, which is to explain kinda-sorta what the Fourier Transform is (i.e. "make a wave using other waves!") but never go into any detail about how you select which constituent waves contribute to the overall wave etc., and so I was always left unsatisfied.
