IN BRIEF:

• 🔊 We linked to the 15-minute weekly Go podcast Cup o'Go when it launched and it's still going strong with ▶️ the latest episode talking about the Reddit strike, Women Who Go, and Fyne.

• If GitHub is looking a little different for you lately, here's why. They've redesigned their navigation system and it's now being gradually pushed out.

• GoLand 2023.3 EAP 5 has landed with improvements to how you update dependencies in go.mod files, plus extra Kubernetes and Docker features.

• The 2023 Stack Overflow Developer Survey results are out and Go has fared reasonably well coming in as the 13th most popular technology (lucky for some), 9th in the list of 'admired and desired' languages, and did very well in the list of top paying technologies too.

• VMware Labs has announced support for Go workers on its Wasm Worker Server.

▶  Comparing Stacks for Building REST APIs: Go vs the World — You’ll need some time to work through these, but it’s interesting to see a single developer take on the task of implementing a CRUD-style REST API in ten different ecosystems. ▶️ The Go-based one leans on the now-archived Mux, but you can also enjoy quick tours of doing the same in Java, Rust, PHP, C#, and others.
