Practical articles on AI, DevOps, Cloud, Linux, and infrastructure engineering.
A curated list of shell one-liners that earn their place in real ops work — the ones I reach for weekly, not the trick-shot variety.
After two years of running Karpenter on production EKS clusters, the NodePool patterns that survived, the ones we replaced, and the tuning that matters.
When LLMs can call tools that change real state, the design decisions that matter most are about what's gated, what's automatic, and what triggers a human checkpoint.
We run a chaos game day each quarter. The scenarios that surfaced real problems, the ones that didn't, and the operational discipline that makes the practice pay back.
Why Postgres connection limits bite at unexpected times, the pooling layer we put in front, and the pool-mode tradeoffs we learned the hard way.
Embeddings turn text into numbers a computer can compare. Here's the working mental model, a runnable Python example, and where embeddings fit in real apps.
Provision real cloud resources with Terraform — a VPC, an S3 bucket, and an EC2 instance — using the standard init/plan/apply workflow.
Generate an SSH key, set up passwordless login, and configure aliases for the servers you use daily — all without copy-pasting yet another long command.
A hands-on intro to prompt engineering. Learn the four levers (role, format, examples, constraints) and watch a vague prompt turn into a reliable one.
A clear walkthrough of Linux file permissions. Read the funny rwx- letters, change them safely with chmod, fix "permission denied" errors with confidence.
Run your first three Kubernetes objects — Pod, Deployment, Service — on a local cluster, then understand why each one exists and how they fit together.
GitOps in plain words — what it actually is, the workflow it enables, and a hands-on demo using Argo CD on a local Kubernetes cluster.
