🕒 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. This time it’s the experimental testing/synctest package which opens up some added opportunities for testing code involving time or concurrency: “It seems that testing/synctest will significantly improve testing code that involves time or concurrency. At work, I’ve already tried it on some flaky tests like the ones above and it’s helped.”

IN BRIEF:

• Mostly noteworthy for its nice sounding version number, Go 1.23.4 has been released.

• 🤖 An interesting result in Cloudflare's 2024 year in review: Go has overtaken Node.js as the most common language they see being used to power 'API clients'/automated requests.

• Microsoft has released new versions of its custom Go builds covering Go 1.23.4 and 1.22.10. (You'd use these for FIPS compliance in the MS ecosystem.)

• 🤖 If you're into working with LLMs and AI from Go, /r/LLMGophers is a new sub-Reddit you might want to help populate.

• Simon Willison tries to figure out what the absolute simplest possible Hugo-powered site would be.
