Opting In to Transparent Telemetry in Go — A debate around adding telemetry to the Go toolchain has been rolling for the past few weeks. Now there’s a new development: “By far the most common suggestion was to make the system opt-in (default off) instead of opt-out (default on). I have revised the design to do that.” There are some downsides to that, of course.

Service Weaver: Google's Framework for Writing Distributed Go Apps — A new open-source framework from Google that lets you “write your (Go) application as a modular monolith and deploy it as a set of microservices” to get the best of both worlds, namely: “the development velocity of a monolith, with the scalability, security, and fault-tolerance of microservices.” If you fancy something more technical and less salesy, Robert Grandl has a quick introduction here.
