Julia Macros for Beginners
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…

Const all the things?
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…

Strict Python function parameters
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...

I'm making a Typescript type-checker in Rust
TLDR; I'm making a Typescript type-checker in Rust. Right now it supports a smaller subset of the type-system and exists as a fun side-project, but the end goal is a compilation tool we can use to make Typescript compilation go brrrr...

My Elm Experience
I've been using Elm since about one year back now. At the start of 2021 I began working with a client that had an existing Elm frontend code base and an early stage backend built in Elixir and Phoenix. This post will be about my experiences running face first into Elm. I'll be vague on some details as I can't share…

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.

Rust in 2022
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

From TypeScript to ReScript
Rewriting the Inhyped.com React frontend in ReScript brought a sound type system and easy JS interop, at the cost of a small community.

Dear sir, you have built a compiler
I am afraid to inform you that you have built a compiler. I know you wanted a “simple prototype” that would just add that one feature to your programming model. You said that “SSA is an overkill” and “it’s just way too much infrastructure to maintain for a simple task” and yet, six months later, you have pile of…

Fortran is easy to learn
Some may think Fortran is an archaic language, and certainly not one that should be taught, but in any respects modern Fortran is an exceptionally good language to teach programming in. Certainly b…

Almost Always Unsigned
Almost Always Unsigned # Written by Dale Weiler Twitter GitHub Last updated Saturday, January 1, 2022 The need for signed integer arithmetic is often misplaced as most integers never represent negative values within a program. The indexing of arrays and iteration count of a loop reflects this concept as well. There…

Why is my Rust build so slow?
I’ve recently come back to an older project of mine (that powers this website), and as I did some maintenance work: upgrade to newer crates, upgrade to a newer rustc, I noticed that my build was ta...
