Why Does “=” Mean Assignment?
Take the following code: a = 1 a = a + 1 print(a) A common FP critique of imperative programming goes like this: “How can a = a + 1? That’s like saying 1 = 2. Mutable assignment makes no sense.” This is a notation mismatch: “equals” should mean “equality”, when it really means “assign”. I agree with this criticism and…

Hacker News now runs on top of Common Lisp

I know it didn’t just come to me in a vision—I have an iterative design process…

Rust After the Honeymoon
Two years ago, I had a blog entry describing falling in love with Rust . Of course, a relationship with a technology is like any other relationship: as novelty and infatuation wears off, it can get on a longer term (and often more realistic and subdued) footing – or it can begin to fray. So well one might ask: how is…
