Go 1.24 Interactive Tour (antonz.org)
Go 1.24 is scheduled for release in February, so it's a good time to explore what's new. The official release notes are pretty dry, so I prepared an interactive version with lots of examples showing what has changed and what the new behavior is.

Build a Database in 3000 Lines with 0 Dependencies (build-your-own.org)
I’ve built a small database in 3000 lines from scratch in Go to learn the core ideas of databases. It’s not that complicated if you approach it in a certain way.

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.

I think Go union type proposals should start with their objectives (utoronto.ca)
At this point I've skimmed a number of relatively serious union type proposals for Go (which is to say, people who were serious enough to write something substantial in the Go issue tracker). One of the feelings I've wound up with as a result of this is that any such union type proposal should probably start out by describing what its objectives are, not what its proposed syntax is.

Go's Weird Little Iterators (mcyoung.xyz)
A second post on Go silliness (Miguel, aren’t you a C++ programmer?): in 1.23, Go finally added custom iterators. Now, back when I was at Google and involved in the Go compiler as “the annoying Rust guy who gets lunch with us”, there were proposals suggesting adding something like this, implemented as either an interface or a func:

Go should sometimes be a no-go (brainbaking.com)
As I will be switching clients next year, I will also be switching programming languages, from Go back to Java. Truth to be told, I’m relieved because of it. The biggest challenges faced were most definitely not related to the choice of programming languages, but after cursing and fighting with Go’s mechanics and philosophy for years, I’m ready to throw in the towel. Depending on the type of software you’re developing, that is. Sometimes, Go should be a No-Go.

Union types ('enum types') would be complicated in Go (utoronto.ca)
Every so often, people wish that Go had enough features to build some equivalent of Rust's Result type or Option type, often so that Go programmers could have more ergonomic error handling.

Good union types in Go would probably need types without a zero value (utoronto.ca)
One of the classical big reason to want union types in Go is so that one can implement the general pattern of an option type, in order to force people to deal explicitly with null values.
