if got, want: A Simple Way to Write Better Go Tests — “There’s an excellent Go testing pattern that too few people know. I can teach it to you in 30 seconds” is quite the pitch. The trick is using both assignments and a comparison on a single if line to make a test easier to read — it’s even used in the standard library.

Cogent’s site itself is built with the framework and compiled to WASM to run on the Web. It...

Go 1.24 Release Candidate 1 Released — This announcement isn’t particularly exciting, but if you want to get ahead of what’s coming in February 2025 with the final Go 1.24 release, the holidays aren't a bad time to have a play. The draft Go 1.24 release notes go into more detail.

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).

🕒 Coming in Go 1.24: An Experiment for Time and Concurrency Testing — A look at another feature coming to Go 1.24 early next year.

At work, I’ve already tried it on...

Echo: Extensible, Minimalist Go Web Framework — Though it’s not too minimal, offering HTTP routing, automatic TLS, data binding, templating, middleware, and different ways to render data out of the box. v4.13.0 removes the JWT middleware from Echo core due to security issues. GitHub repo.

Why Go Slices Still Surprise Me — Slices are a common source of confusion and bugs, and this could be due to the merging of two different use cases into one concept. Sometimes, it’s a 'fat pointer'; sometimes, it’s a dynamic array. Confusing the two is where the pain starts.
