Software engineering is about managing complexity
There is a misunderstanding about software engineering that AI is making increasingly visible: we tend to confuse writing code with building software.

A case against currying
Curried functions are probably one of the first new things you come across if you go from an imperative language to a functional language. In purely functional languages, the convention is to define an n-parameter function inductively by staggering the parameters: applying the function to argument #1 returns a…

Log messages are mostly for the people operating your software
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…

NoiseLang: Where N = 5 is a Dirac delta
A signals-and-noise course left me writing Monte Carlo math on paper and wishing the notation itself would run. Nine years later, with an AI agent doing the heavy lifting, NoiseLang became a real Monte Carlo language that runs the same fused kernel on the GPU, on every CPU core, and on WebAssembly.

80386 Memory Pipeline
The FPGA 386 core I've been building now boots DOS, runs applications like Norton Commander, and plays games like Doom. On DE10-Nano it currently runs at 75 MHz. With the core now far enough along to run real software, this seems like a good point to step back and look at one of the 80386's performance-critical…

Making ASCII Art in Vim
I like using Vim to make ASCII art. I don't use any plugins; Vim already has a bunch of built-in features that are super useful for making ASCII art!

Things I want in a modern relational query language
This was a very old draft I’ve had sitting around for years. The recent discussions of new query languages like Acadia spurred me to revisit, revise, and publish this. I think one of the biggest causes of NoSQL is that… Continue reading →
