I've asked the team behind Cue to come prepared to discuss the limits of configuration management when dealing with different configuration systems, for example, using Terraform, Kubernetes, and GitHub Actions to manage a single project, something that occurs more often than you would think.
Final call! 📣
Join us with @kelseyhightower.com tomorrow, Tuesday, Nov 4, at 17:00 UTC to explore the future of configuration with our Configuration Control Plane, and turn configuration from a source of risk into a source of reliability!

Fun little Go compiler CL merged today: go.dev/cl/706655
Uninlined generic functions have a "dict" arg, since Go generics are neither erased nor monomorphized, but instead instantiated for each "GC shape" (e.g. T=*int and T=*float64 get the same code, but T=int32 and T=int64 do not).

Interesting: the YAML organization has adopted a fork of go-yaml/yaml, also known as gopkg.in/yaml.v3. Beyond security updates for v3, they have begun work on a future v4!
