Sets in Go: Using Maps and Recommended Packages — Go hasn’t got a native data type for sets, but maps can help you implement your own, as well as packages like golang-set. Willem shows us how.

Go's Singleflight Melts in Your Code, Not in Your DB — The last post in a series on concurrency describes singleflight, a non-core package (that’s maintained by the Go team) that ensures a function is only run once and its result reused by later callers. There are loads of use cases, especially around database access.
