Static type checking in the programmable programming language (Lisp)
Static type checking in the programmable programming language (Lisp) There is a misconception that Lisp is a dynamically typed language and doesn’t offer compile-time type checking. Lisp being the programmable programming language that is of course not true.

Dropbox releases PyAnnotate -- auto-generate type annotations for mypy
Updates about mypy, an optional static type checker for Python For statically checking Python code, mypy is great, but it only works after you have added type annotations to your codebase. When you have a large codebase, this can be painful. At Dropbox we’ve annotated over 1.2 million lines of code (about 20% of our total Python codebase), so we know how much work this can be. It’s worth it though
Write You a Haskell ( Stephen Diehl )
There is nothing more practical than a good theory. — James C. Maxwell Hindley-Milner Inference The Hindley-Milner type system ( also referred to as Damas-Hindley-Milner or HM ) is a family of type systems that admit the serendipitous property of having a tractable algorithm for determining types from untyped syntax. This is achieved by a process known as unification, whereby the types for a well-
Typing the technical interview
Previously: Hexing the technical interview. In the formless days, long before the rise of the Church, all spells were woven of pure causality, all actions were permitted, and death was common. Many witches were disfigured by their magicks, found crumpled at the center of a circle of twisted, glass-eaten trees, and stones which burned unceasing in the pooling water; some disappeared entirely, or wa
