Some First Impressions of Go 1.21 — The impending 1.21 release feels more significant than other recent releases due to the items mentioned in this post, including new slice/map API functions (including many that take advantage of generics), structured logging, and the (experimental, opt-in only for now) tweak to loop variable capture.

Wazero 1.3.0: WebAssembly Runtime for Go Developers — The goal here is being Go 1.21 ready (since it’s released next month). That’s important because Go 1.21 will directly support compiling to WASI-backed WASM which, in turn, Wazero will be able to run. Now we’re just waiting to see if Wazero can be compiled to WASM and run by itself.. 😅

  • 🇺🇸 Don't forget that the US outing of GopherCon is taking place this September in San Diego, CA.

  • In the wild, gophers tend to live alone, and many Go-programming gophers work alone too. Last week's Go Time podcast focused ▶️ on solo gophers and the realities of working on a team of one.
