The document discusses the ATS programming language. ATS is presented as a safer alternative to C for systems programming due to its use of dependent types, linear types, and optional garbage collection. It can be compiled to run without a runtime on baremetal systems like an Arduino. The author is looking to spread awareness and use of ATS in Japan by starting a user group and showcasing its use for functional IoT programming.
