PyPy has been working for me for several years now
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…

Three Laws of Software Complexity
I posit that most software engineers (particularly those working on infrastructural systems) are destined to wallow in unnecessary complexity due to three fundamental laws.

Fast Shadow Stacks for Go
tl;dr : Software shadow stacks could deliver up to 8x faster stack trace capturing in the Go runtime when compared to the frame pointer unwinding that landed in go1.21. This doesn’t mean that this idea should escape from the laboratory right away, but it offers a fun glimpse into a potential future of hardware…

Shadama: A particle simulation programming environment for everyone
We present a prototype of a programming system called Shadama. Shadama is designed for writing programs that create, control and visualize large numbers of objects. The basic execution model follows the tradition of StarLogo and its "turtles and patches" abstraction. Turtles, Termites, and Traffic Jams: Explorations…

Generalizing Support for Functional OOP in R
R has built-in support for two functional Object Oriented Programming (OOP) systems: S3 and S4, corresponding to the third and fourth version of the S language, respectively. The two systems are largely compatible; however, they are two fundamentally distinct systems, two systems for a user to understand, two systems…

Runtime code generation and execution in Go
Disclaimer: I won’t expand on why/when you want to do this kind of hack, and you should not do this unless you know exactly what you are doing. Everything I talk about here is completely unsafe and might not be accurate for the future Go versions. This is not a recommendation, but more of a fun story.

Evolution of the ELF object file format
Updated in 2025-09. The ELF object file format is adopted by many UNIX-like operating systems. While I've previously delved into the control structures of ELF and its predecessors, tracing the historical evolution of ELF and its relationship with the System V ABI can be interesting in itself. The format consists of…

Taming floating-point sums
Suppose you have an array of floating-point numbers, and wish to sum them. You might naively think you can simply add them, e.g. in Rust:

Abusing Go's Infrastructure
I apologize if this information is already known, but I couldn’t find any references about it and I wanted to understand what was going on and share with you because I think there is some value doing it. In case this wasn’t known, I apologize to the Go team for not talking to them first and jumping the full disclosure…

A simple core.async job system in Clojure
In my off time (and my on time, for that matter) I've been working on this quirky thing I've called Scinamalink (sounds like 'skinamarink'). Scinamalink lets customers send Magic login links to their users with a single REST API call. If you don't know what a magic
