What a good treat when you are learning something (generating functions in my case) and find a blog post written by someone you know: Dice, (De)Convolution and Generating Functions. Thank you, @demofox.

Also, it’s a good observation that generating functions are like the Z-transform (and also Fourier/Laplace in continuous space). All of those solve problems by transforming into a different space, solving the problem there, and then transforming back.
