Golang sync.Pool is not a silver bullet (wundergraph.com)
When it comes to performance optimization in Go, sync.Pool often appears as a tempting solution. It promises to reduce memory allocations and garbage collection pressure by reusing objects. But is it always the right choice? Let's dive deep into this fascinating topic.

The right way to do data fixtures in Go (brandur.org)
Every test suite should start early in building a strong convention to generate data fixtures. If it doesn’t, data fixtures will still emerge (they’re that necessary), but in a way that’s poorly designed, with no API (or a poorly designed one), and not standardized.

Don't Be Afraid of Types (lmika.org)
I found that there’s a slight aversion to creating new types in the codebases I work in. I saw it during my early days while I was working in Java projects, and I see it today in the occasional Go project. Function bodies with lots of local variables, functions that take a large number of arguments or returning a large number of results, extensions to existing types rather than making new ones. It’s a strange phenomenon.

Goth stack: building front-ends with Go, HTML and a little duct tape (thefridaydeploy.substack.com)
I’ve been a fan of Go for the better part of 10 years now. Its simplicity and portability quickly earned it a place as my language of choice. But the frontend experience has always left something to be desired for me. While powerful, Go templates are a language unto themselves and for any kind of interactivity you’re going to want to reach for some JavaScript or TypeScript.

Decoding JSON sum types in Go without panicking (nicolashery.com)
The Go programming language doesn't have native support for sum types, but we'll see how we can emulate them, how to decode and encode them into JSON, and how in some cases they can help avoid runtime panic exceptions.

Were multiple return values Go's biggest mistake? (herecomesthemoon.net)
The Go programming language is frequently critizied for all sorts of reasons. To name a few crowd favorites: Lack of sum types, lack of enums, lack of null safety, lack of const correctness or immutability guarantees, verbose error handling that still makes it easy to accidentally ignore errors, the infamous time formatting and of course the lack of generics (this one is admittedly outdated).
