When df lies and du swears, look for Loki’s orphaned WAL segments. Our prod cluster filled up every week until we purged legacy boltdb-shipper data from S3. Postmortem, fix steps, and preventive checks summarized.
After seven years running clusters I finally built my first Kubernetes Operator—a Redis PoC in Go with Operator-SDK. This post demystifies CRDs, reconcile loops, defaults, secrets, and status conditions, sharing hard-won lessons and next steps for anyone Operator-curious.
Deploying on Kubernetes doesn't equal disaster recovery. My MSc research showed this clearly—comparing AWS EKS and GKE recovery scenarios with Velero backups taught invaluable, practical lessons.
Early in 2023, challenged by rising Kubernetes issues in production environments, I crafted an audit methodology to diagnose clusters, identify misconfigurations, and establish best practices. Delivered by summer, it enabled clients to transform reliability and performance.
Strapping a Raspberry Pi Zero to my wrist, I built the "PiSpot Watch"—a chunky, lovable smartwatch that briefly challenged the Apple Watch, at least in spirit. From learning FreeCAD and 3D-printing cases, to battling hardware quirks and automating deployments with Ansible—this was my IoT odyssey.
