Data Race Patterns in Go — Uber's engineers analyzed over 1,100 data races and found that it’s much easier than you might think to introduce them in Go "due to certain language design choices." This post breaks down seven of the most common reasons – your code probably engages in one of them too.

Ebiten, the 2D Game Library for Go, Becomes Ebitengine™ — If you want to create a 2D game in Go, whether for desktop, mobile, or even the Nintendo Switch, this remains a great place to start, and now it’s got a new name too (in order to land a trademark in Japan, I'm told). There’s also an Ebitengine Game Jam starting next week, if you want some motivation to give it a try.

(Mostly) Automatic Go Dependency Updates with GitHub Actions — When there’s no defined process ensuring dependencies get updated, well.. you’re going to end up with some outdated packages in your stack. This isn’t a hard task, really, but one that people don’t always think about.
