I started writing this post because, for whatever reason, I keep forgetting what the difference is between a ring and a group, which is funny to me because I never forget the difference between a semiring and a semigroup – although other people do, because it’s quite easy to forget! So, I wanted a fast reference to the kinds of algebraic structures that I am most often dealing with in one way or another, usually because I’m writing Haskell (which has some reliance on terminology and structure from abstract algebra and category theory) or I’m trying to read a book about category theory and they keep talking about “groups.” Wikipedia, of course, defines all these structures, and that’s fine, but what I need in those times is more of a refresher than an in-depth explanation.

Games can be made in many different ways. Many games are made using big, general purpose game engines such as Unity and Godot. I enjoy using the Odin Programming Language combined with Raylib.
Odin is a C-like programming language and Raylib is library for drawing graphics, checking input and playing sounds. So it’s just a program that uses a simple library, no engine!
There are no objectively best ways to create games.

Interesting setup for pet computers. Debian + sway + cage

In modern Java, the visitor pattern is no longer needed. Using sealed types and switches with pattern matching achieves the same goals with less code and less complexity.

There's a concept that I've heard called by a lot of different names, but my favorite name for it is …

A lightning post on logic programming in Haskell to construct a workout weekly schedule given the set of exercises, days and constraints.

build2 is an open source (MIT), cross-platform build toolchain that aims to approximate Rust Cargo's convenience for developing and packaging C/C++ projects while providing more depth and flexibility, especially in the build system.

Using systemd to avoid having to write some risky code

From Erlang, to Elixir and now, GLEAM!?

piku, inspired by dokku, allows you do git push deployments to your own servers, no matter how small they are.

Hare is a systems programming language designed to be simple, stable, and robust. Hare uses a static type system, manual memory management, and a minimal runtime. It is well-suited to writing operating systems, system tools, compilers, networking software, and other low-level, high performance tasks.
