Building Gin: Simple Over Easy — Did you know Gin, the popular Go web framework, was built for a social network that never took off?

Understanding the Go Runtime: Profiling — Jesús is back with another of his deep dives, this time into how profiling works under the hood. If you’ve ever used pprof, you’ll learn exactly what’s going on inside Go to make it work, and what the five different types of profile measure.

IN BRIEF:

A proposal to allow Go doc examples with any signature is now a 'likely accept'. Examples with parameters or return values will appear in docs but won't be run by go test.
/r/golang discussed Go's conservative approach to language evolution. The consensus is that Go's simplicity is a key selling point.
A proposal to add Server.MaxHeaderValueCount to net/http (to mitigate attacks where large numbers of spurious HTTP headers are sent) has been accepted.
Go Report Card has closed after over a decade of scoring the quality of Go repos. We first linked to it in issue 50!
