Programming Language File Extensions That Match ISO 3166-1 Country Codes
Programming language file extensions that match ISO 3166-1 alpha-2 country code
I explored the surprising overlap between programming language file extensions and ISO 3166-1 alpha-2 country codes. Starting with Rust's .rs extension coinciding with Serbia, I compiled a list of other matches like Python for Paraguay and Ruby for Russia. This curiosity-driven investigation reveals how technical standards and geographical identifiers sometimes intersect in unexpected ways.
Either by a sheer coincidence or someone playing 5D chess, .rs is also the file extension for the Rust programming language, which is why the domain name of every other Rust project now belongs to Serbia.
