The article discusses the creation of a portable executable format called αcτµαlly pδrταblε εxεcµταblε, which allows a single binary to run on multiple platforms, including Windows, macOS, and Linux. This is achieved by encoding the binary in a way that is compatible with multiple file formats, including ELF, PE, and MachO. The project, called Cosmopolitan, aims to make it easy to write software that can run on any platform without modifications. The article also touches on the potential benefits and limitations of this approach.
