An Introduction to Generics — It’s brief but it’s as official an introduction as it gets with two Go project members introducing generics (as now generally available in Go 1.18) focusing on type parameters, type sets/constraints, and type inference in a well-explained set of examples. Some caution is advised, however, to tread carefully when deploying generic code in production. There’s a 30-minute talk from last year’s GopherCon, too, if you prefer video.

How Glean Analyzed and Fixed a Go 'Memory Leak' (Sort Of) — It looked like a memory leak, smelled like a memory leak, and while it was ultimately down to a quirk of memory management that you’re not going to run into in Go 1.16+, you might enjoy this little look under the covers.
