Extending Python with Rust
Sometimes a pure Python script can't just deliver the performance we need. When that's the case we have to resort to writing our logic in a "fast" compiled language like C or Rust and expose the function with through a Python module. This way we get the best of both worlds. Today I focus on how to use Rust for writing…

Why static languages suffer from complexity
People in the programming language design community strive to make their languages more expressive, with a strong type system, mainly to increase ergonomics by avoiding code duplication in final software; however, the more expressive their languages become, the more abruptly duplication penetrates the language itself.

Using unwrap() in Rust is okay
One day before Rust 1.0 was released, I published a blog post covering the fundamentals of error handling . A particularly important but small section buried in the middle of the article is named “ unwrapping isn’t evil ”. That section briefly described that, broadly speaking, using unwrap() is okay if it’s in…

I hate LaTeX, I love LaTeX
Everyone who knows me IRL (and, I suppose, who follows me online for long enough), knows that I have a… special relationship with LaTeX. I think it has something to do with its obscurity, when it wasn’t specifically made to be obtuse, and then being so good at what it does — which is typeset documents. It doesn’t help…

The First Lisp Compiler
This page examines the earliest surviving Lisp compiler, written by Timothy Hart and Michael Levin around 1961. To avoid repetition of phrases like “the compiler”, we will use the abbreviation “ HLC ” (for “Hart–Levin Compiler”) to refer to it. The HLC was introduced in M.I.T. AIM -039 and documented more fully in the…

Learning Go as a Python Developer: The Good and the Bad
I've been thinking about supplementing another language to Python for some time – mainly to cope with areas Python struggles with, or is a pain to use (which I'll go over in a minute). I had used C/C++ some years ago, but don't want to go back to them. C
