Go Protobuf and the New Opaque API — The existing protobuf module is here to stay, but now we get an additional API that provides a more loosely coupled abstraction for working with protobufs without being tied to their underlying in-memory representations. The benefits? Memory efficiency, lazy decoding, and fewer opportunities for bugs.

8. Go Performance from Version 1.0 to 1.22 — Two years ago we enjoyed the author’s Go performance analysis from Go 1.2 to 1.18. This was an update taking things from Go 1.0 through to 1.22 (the latest version back in April).

4. Rust vs Go in 2024? — A perennially popular post from yesteryear was tweaked for 2024 with a comparison of the ‘both awesome’ languages including what they’re both good at, their key differences, and some trade-offs to consider. More recently, however, John has asserted that Rust and Go are better off together than apart.
