On the Topic of Making Simple Useful Things (A Distributed Counter)
Counting things across multiple servers sounds trivial. It is not. A walkthrough of the design space for distributed counters, from atomic Redis scripts to per instance tracking with automatic cleanup of dead instances, and the Rust crate I built to handle all of it.

Projects
Laye
Framework-agnostic RBAC library for Rust with composable AccessPolicy rules and plug-and-play middleware for actix-web and tower/axum.
