errtrace: An Alternative to Stack Traces for Your Errors — Inspired by Zig, errtrace is an experimental package to trace an error’s return path through a Go program, i.e. the code path that the error took to get to the user, which may well be different to the code path that led to an error. Luckily, the repo has a comparison, if you’re confused.

Turning a Go App into a 'Static' WASM-Powered Site — The author built a tool in Go to convert CRDs (custom resources in Kubernetes) into YAML and wanted to offer the tool online.
