Walking with filesystems: Go's fs.FS interface (bitfieldconsulting.com)
The new io/fs package introduced in Go 1.16 gives us a powerful new way of working with filesystems: that is, trees of files. In fact, the fs.FS interface can be used with more than just files: it abstracts the idea of a path-value map.

Extensible WASM Applications with Go (go.dev)
Go 1.24 enhances its WebAssembly (Wasm) capabilities with the addition of the go:wasmexport directive and the ability to build a reactor for WebAssembly System Interface (WASI). These features enable Go developers to export Go functions to Wasm, facilitating better integration with Wasm hosts and expanding the possibilities for Go-based Wasm applications.

We replaced our React front end with Go and WebAssembly (dagger.io)
A few weeks ago, we launched Dagger Cloud v3, a completely new user interface for Dagger Cloud. One of the main differences between v3 and its v2 predecessor is that the new UI is written in WebAssembly (WASM) using Go. At first glance, this might seem an odd choice - Go typically isn't the first language you think of when deciding to program a Web UI - but we had good reasons.

Go Data Structures: Interfaces (2009) (swtch.com)
Go's interfaces—static, checked at compile time, dynamic when asked for—are, for me, the most exciting part of Go from a language design point of view. If I could export one feature of Go into other languages, it would be interfaces.

Go Data Structures (2009) (swtch.com)
When explaining Go to new programmers, I've found that it often helps to explain what Go values look like in memory, to build the right intuition about which operations are expensive and which are not. This post is about basic types, structs, arrays, and slices.

Go 1.24's go tool is one of the best additions to the ecosystem in years (jvt.me)
For those that aren't aware, one of the big changes in February's upcoming Go 1.24 release is the new go tool command, and tool directive in the go.mod to manage any tools your project uses. I'm incredibly excited about this, and in my opinion, this is one of the best changes we've had in recent years in the ecosystem as a whole.

Alibaba, Datadog, and Quesma Join Forces on Go Compile-Time Instrumentation (opentelemetry.io)
Standards are only useful if they’re widely adopted, and adoption is only effective if the available tooling facilitates it. I imagine SI units would not have been too popular when they were introduced if you had to build your own scales to weigh things in Kilograms!

The most recent one, Contributors Summit, is a nice write-up on the issues that the Go contributors have been talking about. While reading it, I stumbled upon a sentence that made me write this post.

Go is a well designed language, actually (mattjhall.co.uk)
In many ways 2009 decided my future career. I was thirteen and had just scored my first goal in a competitive football match - a lovely one-two with the winger finished by a powerful strike into the top left corner. Sadly the talent scouts were missing that day. Whilst I was dreaming of Wembley, Go was announced to the world.

Go Upgrade Checklist (hakann.substack.com)
Upgrading your service to a new golang major release is supposed to be a painless process thanks to the Go 1 promise of compatibility. However, there can always be small issues around security updates, packages, tools, linters, etc. If you have an uncritical standalone service, it is probably best to upgrade and see if everything works as expected.
