Coalton Playground: Type-Safe Lisp in the Browser
I wanted to share a side project I’ve been tinkering with for a while and finally got around to shipping: Coalton Playground – basically a web-based REPL for Coalton, which is this inte…

Recto – A Truly 2D Language
Recto is a 2D programming language that uses nested rectangles as its core syntax, encoding structure and recursion directly in space instead of a linear stream of text. Recto explores new ways to write, parse, and reason about code—and even natural language—spatially.

Generic Containers in C: Safe Division Using Maybe
Martin Uecker, 2025-08-10 I discuss the implementation of type and bounds safe generic containers in C. Previously, I discussed a span type , bounds checking using arrays . and a a vector type . This time, I will discuss maybe inspired by Haskell. This type can used to return a value that may not exist, e.g. because…

Zig's Lovely Syntax
It's a bit of a silly post, because syntax is the least interesting detail about the language, but, still, I can't stop thinking how Zig gets this detail just right for the class of curly-braced languages, and, well, now you'll have to think about that too.

Partially Matching Zig Enums

Undefined Behavior in C and C++ (2024)
In some ways, that's because C is a lower-level language, closer to assembly; it just gives you what the underlying machine gives you.

Why tail-recursive functions are loops
One story every computing enthusiast should hear is the lesson ofhow loops and tail-recursion are equivalent. We like recursivefunctions because they’re amen...

Zig Error Patterns
Although I try to make good use of the debugger, I am quite used to print-based debugging, especially for unit tests. I wanted to explore some tricks to improve print-based debugging, and also incorporate the debugger more.

My Ideal Array Language
The fundamental units of computation available to users today are not the same as they were 20 years ago. When users had at most a few cores on a single CPU, it made complete sense that every program was written with the assumption that it would only run on a single core.

Typed languages are better suited for vibecoding
My >10 year old programming habits have changed since Claude Code launched. Python is less likely to be my go-to language for new projects anymore. I am managing projects in languages I am not fluent in—TypeScript, Rust…

C++26 Reflections adventures and compile-time UML
The first thing I do every time I need to learn a new codebase is to start drawing the UML diagram of its classes, and usually give up soon after I started. The process of doing it manually is certainly useful, but now with reflections I figure it would be fun to try to generate it instead.

The /o in Ruby regex stands for "oh the humanity "
Your code using the /o modifier Source: wikipedia Hi there! Do you like Regex? Do you like performance? Do you like creating confounding bugs for yourself rooted in the mechanics of the Ruby VM itself? If you said yes to all of the above, have I got a feature for you! But first, let’s start with a story. The cliffs of…

Resizable structs in Zig
In this post I will make the case for the concept of a “runtime resizable struct” in Zig. I will then design an API by exploiting Zig’s powerful comptime functionality.

Use Your Type System
Today I'm discussing a trivially simple technique that I've rarely seen used in production codebases. In programming, we often need to deal with simple values that can be represented by simple, generic types built into our programming language or provided by libraries: types like integer, string, or UUID. In any

Why I write recursive descent parsers, despite their issues (2020)
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…

Hacking Coroutines into C
A while ago, I was part of a team developing embedded software. The software was deeply rooted in state machines - dozens of them—spread across multiple functions. While this architecture is common in embedded development, especially for systems without an operating system, I started to question: Is this really the…

Working through 'Writing A C Compiler'
