SwissMap: A Smaller, Faster Hash Table for Go — The creators of the DoltDB database have open-sourced SwissMap, a Go port of a hash map from Google’s Abseil library. It uses less memory than Go’s built-in map and is well-suited for performance-sensitive contexts where memory use for large hash tables is a concern – though, as always, there are tradeoffs to consider. (GitHub repo.)

🎂  Go 1 Released 11 Years Ago — A quick jump back in time to March 2012 when “Go version 1” was officially released. A lot has changed since then, but Andrew ended the post with one thing that is still true: “There has never been a better time to be a Go programmer.”

The Adapter Pattern in Go — How do you test a database without a database? It’s not a trick question. There’s a synergy between testability and good design, and the adapter pattern can help you decouple business logic (“knowing about widgets”) from persistent storage (“knowing about Postgres”).

gotraceui: A GUI App for Viewing Go Execution Traces — Meant to be a faster, more accessible, and more powerful alternative to go tool trace with a Gio UI-powered interface tuned specifically to the unique characteristics of Go traces.

go-nbd: Pure Go NBD Server and Client Library — NBD means Network Block Device and in Linux this provides a mechanism for providing block devices (e.g. a hard drive) over a network rather than in local hardware. With go-nbd, you can build your own abstractions and bridges, such as to turn a file, byte slice, S3 bucket or other io.ReadWriter into a fully-fledged block device.
