Introduction The other day I was reading this blog post covering existential types in Rust (also known as impl Trait or opaque types). In that blog post, the author makes the following claim. We’re going to have to take a slight diversion into type theory here because it motivates a result that is perhaps intuitive…
What do you think about when writing a new function in Python? The function name, parameter names, optional/required parameters, and default arguments are all on the list. Here is a simple Python f...

ECMAScript supports proper tail calls. How come browser don't support it?
In Python as in other programming languages, this grand principle encourages software architects to escape from Object Orientation and enjoy the simpler practices of Object Based programming instead.
Last week someone posted a /r/cpp thread titled “Declaring all variables local to a function as const”: Ok, so I’m an old-school C++ programmer using the language now since the early ’90s. I’m a fan of const-correctness for function and member declarations, parameters, and the like. Where, I believe, it actually…
My engineer friends are surprised when I mention I know and I even wrote code in the D programming language (aka Dlang).
In my previous blog post on pointer provenance, I have shown that not thinking carefully about pointers can lead to a compiler that is internally inconsistent: programs that are intended to...
Learn Rust to 80% in 5 minutes by leveraging your existing JavaScript knowledge. In this article, I list a number of differences Rust has compared to JS that is crucial to understanding it.
A few thoughts on why I think you should learn Racket.

Zig lets you run code during compilation. What are the implications?

The yearly benchmarking Ruby post
Macros are a powerful and interesting feature of the Julia programming language, but they can also be confusing. Users coming from Python, Matlab or R have not come in contact with similar constructs before, and they require a different way of thinking about code. This article is supposed to be a simple introduction…
In previous years, the core team have asked the community to write new years blog posts about Rust in the coming year. They haven't this year, but I wanted to write one anyway. However, it turned out to be harder than expected. Perhaps that's due to Rust being in an
They have potential to be more than "no static types", but that hasn't happened.
Rewriting the Inhyped.com React frontend in ReScript brought a sound type system and easy JS interop, at the cost of a small community.
Notable programmers describe understanding and coding in LISP as a semi-religious experience. What gives the language this power?
Just my website. Some Elixir, some Ruby, some more exotic languages and general thoughts on tech.
I’m a Haskell failure, don’t tell anyone! Recently I encountered some dubious error handling code. Not only was it failing, it was failing WRONG 1. This frus
Perverse incentives surrounding best practices
The code formatting and typography is frequent, controversial but probably unavoidable topic among programmers. This document contains some representative and possibly, relevant examples of the Lisp code.
Master them in 20 minutes. Use them every day.
Let me show you characteristics of APL that will influence your understanding of programming concepts and the way you use other languages.
One of the things people often complain about when doing Async Rust is cancellation. This has always been a bit confusing to me, because it seems to me that async cancellation should feel a lot like panics in practice, and people don’t complain about panics very often (though they do sometimes). This post is the start…
I've debated with myself for several years about whether or not to write this down. After so much time has passed, the facts are confused, 20/20 hindsight creeps in, and selective memory plays a role in how fairly I can portray the events. Many reporters have asked me my version of these past few years, several have…
