Kubernetes 1.37 Really Can Flag Unused PVCs, but the Viral YAML Is Wrong
A post making the rounds says Kubernetes 1.37 adds an unusedSince field to PVC status. The feature is real and it is genuinely good news for storage bills; the YAML being shared shows an API that does not exist. Here is what KEP-5541 actually shipped, the correct fields, and a working query for "PVCs unused for 30 days".
WAL as the Source of Truth: What Lakebase Storage on S3 Means for You
Neon published a deep dive on the storage engine behind Lakebase Postgres: the write-ahead log is the database, S3 holds the history, and Postgres itself runs stateless on top. This is the reader-level version, with a hands-on session where we watch LSNs move, delete a table, and branch back to the moment before the mistake in under a second.
The Anatomy of Kubernetes Persistent Storage: PV, PVC and the Parts That Bite
A PersistentVolumeClaim is a request and a PersistentVolume is the thing you get. That part takes five minutes to learn. The lifecycle rules underneath, which decide whether deleting a claim also deletes your data, are where teams lose production volumes.
The Everything-on-Your-Branch Architecture
For a decade "branch the database" has meant a copy of the schema and rows. But your app is also files, backend code, and model config. Neon now forks all of it on one branch: Postgres, object storage, functions, and the AI gateway, together and isolated. I branched a full-stack project to prove it.
