Hacker News with Generative AI: Lambda Calculus

Making Sense of Lambda Calculus 0: Abstration, Reduction, Substitution? (aartaka.me)
I am a programmer. A Lisp programmer, in fact. I have a creeping desire to understand Lambda Calculus because it's a powerful and elegant tool and an inspiring idea underlying many functional languages and idioms. I use lambdas every day, without knowing their secret power. Might be useful to unleash this power and tame it for productivity.
Damas-Hindley-Milner inference two ways (bernsteinbear.com)
Damas-Hindley-Milner (HM) is a type system for the lambda calculus (later adapted for Standard ML and the ML-family languages) with parametric polymorphism, aka generic functions. It sits at a sweet spot in PL design: the type system is quite expressive, and there are well known type inference algorithms that require absolutely no annotations from the programmer.
Introduction to the λ-Calculus (lawrencecpaulson.github.io)
The λ-calculus has had a pervasive impact on computer science – and not just in functional programming languages, most of which can be viewed as extended λ-calculi, but even in modern systems programming languages such as Rust.
