I have written about the kgateway vulnerabilities I’ve found, and also why IMO they should have a bigger score. Also regardless of the score, remember to always keep your stuff updated :)

Oooh this is nice. I know a lot of Kubernetes subprojects that use mkdocs + material, would for sure follow this effort!
Also links validations and better search ❤️

I've been a fan of Material for MkDocs since I was introduced to it through the stucco #powershell module. The stale upstream MkDocs community represented a lot of risk through, so the Material team have introduced a new SSG I'm excited to try. Faster builds and better live previews are 💪
Zensical – a modern static site generator.
We're excited to release @zensical.org, our new SSG that is compatible with Material for MkDocs:
– 5x faster rebuilds
– Modern design
– Blazing-fast search

Apropos of nothing: now would be a real cool time for the CNCF to realize that North America includes both Mexico and Canada and decide that KubeCon NA can be somewhere other than the US

This is also a nice read, to understand some AWS internals, some architectural decisions impacts, etc
