#Kubernetes community, SIG-apps is working on adding new metrics to the StatefulSet controller upstream. Are there specific metrics you’ve felt were missing that would help in debugging or operating StatefulSets in production?

Ok, I have a rant I have to let go of.
If you generate a change to an open-source project fully with AI, didn't read, review, understand, and questioned it, then at least have the decency to say this on the PR description.
You're stealing people's time by making them review it for you.

My latest post on @OReillyMedia. Many Silicon Valley investors and entrepreneurs even seem to view putting people out of work as a massive opportunity. That idea is anathema to me. It’s also wrong, both morally and practically.

Constraints in Go — Bitfield Consulting
Freedom is nothing without constraints, and Go’s generics gives us a powerful way to build polymorphic types and functions constrained by type sets . Let’s geek out.

No one gets promoted for removing chaos or saying no to prematurely built artifacts that are guaranteed to drag the company down. Until this culture doesn't change, I don't expect anything to change.

This is 100% true. I’ve been seeing this for a while. Knowing how things work deeply is a super power, and one you can use to create better products.
In the age of AI, short form video and hot takes, the competitive advantage of the future is the ability to go deep, read the docs, build something new, learn hard things that take time.
