Your executable is a SQLite database

This article discusses a clever Linux technique that turns a SQLite database file into an executable binary. By setting the SQLite file's application ID to 'SELF' and arranging ELF components into SQLite tables, a custom interpreter can execute the file. The article also explains how to use binfmt_misc to register the pattern for automatic execution, with an example for NixOS and a generic registration command.
