TL;DR I built an “Ops Dream Worker” — a Kubernetes CronJob that runs at 3 AM, inspects the cluster, identifies improvements, and files GitHub issues with specific fixes. It runs entirely on local models (Mac Studio M3 Ultra), costs $0 per run, and went through 240 A/B test iterations to optimize the prompts. The anti-hallucination patterns were harder to get right than the analysis itself. The idea I have a k3s cluster with ~40 deployed services. I maintain it solo. There’s always something that could be better — a deployment missing resource limits, a CronJob that’s been failing silently, an ingress without SSO protection, a container image with known CVEs. These improvements pile up because I’m usually focused on building features, not auditing infrastructure. ...

TL;DR PiKey is a Raspberry Pi project that spoofs a Logitech K380 Bluetooth keyboard and mouse. It jiggles the mouse to prevent idle detection and auto-types LLM-generated text to simulate human activity. The device appears as a standard Bluetooth HID peripheral – no drivers or software needed on the target machine. Three full implementations exist: Python (primary), Rust (static binary), and C (minimal dependencies). The whole thing was inspired by a Reddit thread on r/overemployed where someone asked for exactly this device. ...

TL;DR I replaced Open WebUI with OpenClaw – a lighter, WebSocket-based AI assistant gateway that installs from npm, supports multiple chat channels (web, Telegram, Discord, WhatsApp), and deploys on k3s as a single Deployment with a custom Docker image. The primary model provider is Anthropic’s direct API (Claude Sonnet 4.5), with LiteLLM/Bedrock as a fallback. The biggest deployment lesson: OpenClaw binds to loopback by default, which makes it invisible to Kubernetes Services and health probes. The fix is --bind lan, which requires a gateway token for authentication. ...

TL;DR The Jellyfin HA conversion touches a .NET 10 codebase, Entity Framework Core migrations, Kubernetes manifests, Terraform infrastructure, PostgreSQL operations, and FFmpeg transcoding pipelines. No single AI model understands all of this equally well. So I used four of them — the same multi-model planning pattern that shipped dnd-multi in a single day and that I documented in the LLM GitHub PR workflow. This post covers how I adapted that pattern for infrastructure work, what each model caught, and why planning is where all the human time should go. ...
