The DevOps Job Market Just Told Me Something Important About Where We're Heading

Last month, I got pinged by three different companies asking if I knew any DevOps engineers. When I asked what they were offering, the answers ranged from "competitive" to "we're flexible." None of them seemed to realize they were competing for the same tiny pool of talent. It ma...

I Was Wrong About Kubernetes Swap, And It Actually Matters Now

I spent the last three years telling anyone who'd listen that swap in Kubernetes was a terrible idea. "Just buy more RAM," I'd say confidently, usually while configuring another overprovisioned node pool. Then I got a project involving AI agent workloads, and suddenly my certaint...

When Your Docker Image Bloats from 900MB to... Wait, How Did We Get Here?
