@Robusto thanks to you I still have the link to the original. He had to unlist it and replace it with a censored version because apparently Stalin is still watching even today. Delicious.
@SEJPM ELL: There is a chance it will get closed as a dictionary question (and OPs of migrated stuff never respond) but it will receive answers and probably a couple of upvotes as well.
@SEJPM Also it's poorly posed for ELU. The word 'modulo' and how it is used in English is interesting, but the question is asking 'How in general are all the versions of mod, modulus, modulo, etc are used?'. It's off-putting on ELU to request a summary.
