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. Compiling it all into a WebAssembly powered app that can be hosted in a static fashion, while offering dynamic features (that aren't reliant upon a server), wasn’t easy, but it works.
