Functional correctness -- Haskell-ing your way to reliable code (hackover2024)

In the realm of modern software development, ensuring correctness and reliability of software systems is paramount. Functional programming langaunges like Haskell offer a unique approach to achieving these goals through strong type systems, immutable data structures, and pure functions. Despite its practical benefits, functional programming is not yet widely-used in mainstream development. Here, we'll take you on a gentle exploration of the fundamentals of functional programming, emphasizing concepts like referential transparency, purity, and correctness through verifiable specifications. Through practical examples and approachable explanations, we will illustrate how Haskell's paradigms can lead to a more robust and maintainable codebase. This talk serves as a friendly guide for beginners eager to dive into the world of functional programming and to harness its power to write verifiably correct, maintainable software.
