It should be mentioned in outro/intro that there are already some good libraries to do linear algebra out there and that we don't have to reimplement vector operations ourselves in 2023.
-> icedquinn's icedgmath: <https://sr.ht/~icedquinn/icedgmath/> -> Scinim's nimblas: <https://github.com/SciNim/nimblas> (if telling in layman's terms what a BLAS implementation and Nim bindings are does not overload your tutorial). -> mratsim's Arraymancer: <https://github.com/mratsim/Arraymancer> Have you consider the eventuality to use <https://github.com/pietroppeter/nimib> to automatically check your tutorial's code? I am looking forward to the more advanced tutorials you mentioned.
