Go Weekly

go-callvis: Visualize the Call Graph of Go Programs — We first linked to this project over six years ago, but it’s still going strong and has reached version 0.7. 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? — 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.

Kubernetes API Access Security Hardening — The control plane controls k8s nodes, nodes control pods, pods control containers... But what controls the control plane?

Teleport | goteleport.com sponsor

Go 1.20.4 and Go 1.19.9 Released — Minor releases that include three security fixes for html/template, all (1, 2, 3) oriented around sanitization and improper handling of Web content.

A 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.

▶  Production Ready Concurrency — Concurrency is difficult to get right even when a language offers convenient features for working with it. Egon’s preference? Avoid concurrency where possible. But for when you can’t.. he has some tips.

🛠 Code & Tools

mimetype: Library for Detecting MIME Types and Extensions — Supporting 172 different types, you pass in data, a stream, or filename and, hopefully, find out what type of data you’re working with.

Dolt 1.0: It's Like Git.. for Data — Dolt is an SQL database that introduces git-like forking, cloning, branching and merging features: “It’s like Git and MySQL had a baby,” they claim. GitHub repo.
