Profile-Guided Optimization (PGO) in Go 1.21PGO has been a popular topic for blog posts recently, but here’s an as-close-to-official-as-it-gets example of using it to improve code, including deeper dives into two major optimizations enabled by the process. If nothing else convinces you to give it a shot, consider this: “In Go 1.21, workloads typically get between 2% and 7% CPU usage improvements from enabling PGO.”

Michael Pratt (The Go Team)

And if you fancy another article on the topic, Landon Clipp has another practical intro to PGO here that provides more of a "user-facing perspective."

Scaling gopls for the Growing Go Ecosystem — The official Go blog gives us two posts to sink our teeth into this week. This time, the spotlight shines on the gopls Go language server used by a variety of IDEs to enhance their Go support. This post looks at some recent advancements and speedups, and invites you to take this survey if you’re a gopls user.

  • Go 1.21.1 and 1.20.8 have been released. Minor point releases with some security fixes.

  • I want to take another opportunity to link to The Free Gophers Pack by Maria Letta – it's a helpful set of Go gopher illustrations (based upon the original by Renée French) and we used it in today's lead image.

  • Talking of the Go gopher, back in 2016 Renée French gave an ▶️ interesting talk about the Go gopher, how it came together, and some of Renée's favorite adaptations of it.

  • If you've got to write any C++, coost is worth a look. It's a tiny Boost-esque library to make C++ easier to write and with a little more Go flavor, including Go-style coroutines.

  • IEEE Spectrum has released its list of 'top programming languages' in 2023 and Go does pretty well in 8th place.

  • 📅 🤖 In a few weeks I'm attending the AI Engineer Summit in SF – if you're into the rapidly growing field of using AI and ML tools and technologies alongside software development, check it out. Even if you can't attend, you can snag a free remote ticket to watch from afar.
