Building Deterministic Systems with Non-Deterministic Tools
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.
Large Language Models are probabilistic text generators. Their raw outputs cannot be trusted for correctness. So how do you build reliable software with unreliable assistants?
You don't ask for answers. You ask for tools that produce answers.
