Finding Bugs with Fuzzing — The final post in a series about fuzz testing in Go (you can start here) wraps things up with a practical example of finding and fixing a subtle bug in Go code using the process.

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.. 😅

  • sqlc is a popular tool for working with SQL that compiles queries into type-safe Go code, and its creators have great news: they will now be working on sqlc full-time.

  • 🇪🇺 GopherCon Europe 2023 took place a few weeks ago and Benjamin Bryant has shared this 'totally nonprehensive' recap of how it went, focused mostly on the nice people he met which, to be fair, is what conferences are all about.

  • 🇺🇸 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.
