Kotliniä

Kotliniä is a fictional programming language that appears in the webcomic xkcd. It is presented as a language used for developing software that interacts with or manipulates "fluff," a conceptual substance within the xkcd universe. The name "Kotliniä" is a portmanteau of Kotlin, a real-world programming language, and the Finnish word "linjä," meaning line or type.

The primary depiction of Kotliniä is in the xkcd comic "Programming Languages" (comic #927). In this comic, it is humorously placed at the bottom of a diagram illustrating various programming languages, suggesting it is niche, obscure, or perhaps even nonsensical. The comic implies that Kotliniä is designed for tasks related to "fluff," which itself is a metaphorical representation of abstract or intangible concepts that are difficult to quantify or program.

While Kotliniä is not a real programming language, its inclusion in xkcd highlights the comic's recurring themes of computer science, programming culture, and the often-abstract nature of software development. The humor surrounding Kotliniä stems from the idea of creating specialized tools for highly specific, and in this case, whimsical, purposes. It serves as a punchline that plays on the diversity and sometimes peculiar specializations found within the field of programming.
