[go-callvis: Visualize the Call Graph of Go Programs](https://github.com/ofabry/go-callvis) — We first linked to this project _over six years ago_, but it’s still going strong and has reached [version 0.7.](https://github.com/ofabry/go-callvis/releases/tag/v0.7.0) The idea is simple: turn the call graph of a Go program into a visual overview courtesy of Graphviz. You can also navigate the graph if you use its interactive viewer.

👀 [.ʕ◔ϖ◔ʔ As an Alternative to `.go`?](https://github.com/golang/go/issues/59968) — It’s nice to see Russ having some fun after the more serious telemetry proposal. Inspired by another language’s attempt to use an emoji as a filename extension, Russ considers an interesting alternative to `.go` that looks a little more gopher-y.

[A FAAS in Go with WASM, WASI and.. Rust?](https://eli.thegreenplace.net/2023/faas-in-go-with-wasm-wasi-and-rust/) — Eli won me over straight away with _“This post is best described as a technology demonstration.”_ There are a lot of moving parts here, but the idea is showing how you could create a simple serverless FaaS (Functions as a Service) system in Go that could run modules written in any language that can target WebAssembly.
