About This Blog

This blog documents learnings from building Angzarr — a polyglot event sourcing framework. The framework core is written in Rust, so examples here are primarily Rust.

Angzarr doesn't require Rust. Client SDKs exist for Go, Python, Java, C#, and C++. The author — a polyglot developer — doesn't believe Rust is the best language for everything. It is the right choice for this framework's core, and building it has produced these learnings.

The Rust should be readable by most programmers. If you have questions: consult The Rust Book, ask an LLM, or email the author.

This post has moved to Append Only, my main blog. Future updates will live there.

The Angzarr blog will keep covering things specific to the framework. General software, AI tooling, and workflow lessons now live with the rest of my writing.
