Plex is simultaneously the most popular self-hosted media server and the most misconfigured. Half the people running it are transcoding everything to the server's CPU, paying the Plex relay tax on remote streams, and wondering why their NAS is sweating. Let's fix that.

Google Stadia had the best cloud gaming latency anyone had seen — and then Google killed it anyway. A eulogy from someone who was there from day one.

That filing cabinet won't sort itself. Paperless-ngx OCRs, auto-tags, and makes every document searchable. Here's the Docker setup that fixes it.

Browser ad blockers miss half the ads. DNS blocking kills them everywhere — TV, phone, game console, everything. Pi-hole vs AdGuard Home: here's which one to run.

Obsidian Sync is $10 a month. Your notes are Markdown files. There's a free plugin, a Docker container, and about 20 minutes standing between you and never paying that bill again. Here's how to actually do it without losing your mind or your notes.

Firebase is convenient right up until your bill is $300/month or Google quietly deprecates the product you built on. Appwrite is self-hosted BaaS — auth, databases, file storage, serverless functions, and realtime — on hardware you control. Here's how to set it up and build something real.

Docker Desktop got expensive and RAM-hungry. Colima is the lean alternative. OrbStack is the one everyone's actually using now. Here's the honest breakdown for Mac developers.

Pulling unscanned images onto your server is a gamble. Trivy finds the CVEs. Cosign proves the image hasn't been swapped out. Here's how to add both to your workflow.

You want to self-host your git. Noble. Responsible, even. But now you're staring down three options and a Reddit thread that's somehow both 4 years old and still being argued about. Gitea, Forgejo, GitLab CE — let's cut through the noise and figure out which one won't ruin your weekend.

Falco watches every syscall your containers make and screams when something sketchy happens. Like someone exec'ing a shell inside your nginx container at 3am.

WireGuard is fast out of the box, but default config leaves throughput on the table. Tune MTU, use the kernel module, and benchmark what you actually get.

Tailscale takes WireGuard's speed and wraps it in a control plane that handles key exchange, routing, and ACLs automatically. Here's everything beyond 'tailscale up'.

Traditional automation is just very fast copy-paste. When your email filter breaks because someone wrote "URGENT" in lowercase, you realize rule-based logic has limits. Connecting n8n to a local LLM turns "if this then that" into "figure this out and do the right thing."

You're paying $20/month to Zapier to shuffle data between two services that are both free. There's a better way. n8n and Node-RED are two self-hosted automation tools that can replace the SaaS middlemen — and they'll both run happily on a $15 VPS or your home server.
