Caddy is the simplest reverse proxy for self-hosted services. It gets and renews TLS certificates from Let’s Encrypt with zero config. Install the static binary, write a Caddyfile with three lines per service, and Caddy handles HTTPS, HTTP/2, OCSP stapling, and renewal on its own. That replaces hundreds of lines of Nginx config and separate Certbot cron jobs.

If you run even a handful of services on a home server or VPS, a reverse proxy with proper TLS is non-negotiable. Caddy makes this painless, so there’s no excuse to skip it.

Running CI/CD through GitHub Actions or GitLab CI is handy until it isn’t. Free tier minute limits run out fast. Private repos cost more than you’d expect. And if your code is sensitive, you’re sending every push through someone else’s servers. Self-hosting your pipeline sidesteps all of that.

Gitea is a light, self-hosted Git service. It has added GitHub Actions-compatible workflow support through a piece called act_runner . The workflow YAML syntax is near-identical to GitHub Actions. So teams who already know that ecosystem can move over with little friction. This guide walks through a complete, production-ready CI/CD stack on Linux using Docker Compose.

Redis Streams give you a light, self-hosted option versus Apache Kafka for event-driven data pipelines. You get append-only log semantics, consumer groups with ack tracking, and sub-millisecond latency on a single Redis 7.4+ instance. Producers XADD events to a stream. Consumer groups read with XREADGROUP in Python via redis-py . Manual XACK calls plus a pending entry list (PEL) give you at-least-once processing.

What follows covers stream basics, consumer groups with failure recovery, a full producer and consumer pipeline with a dead-letter queue, and the ops practices to keep Redis Streams healthy in production.

If you are building a home lab in 2026, the most consequential decision you will make is what hardware to run it on. Rack servers are loud, power-hungry, and overkill for most people. A Raspberry Pi cluster is fun but constrained. The sweet spot - and has been for the last couple of years - is the mini PC.

The market has matured. You now have three distinct tiers worth considering: Intel N150 machines for single-purpose appliances, Intel N305 machines for general-purpose home labs, and AMD Ryzen AI class mini PCs for heavy virtualization or local AI inference. Each tier makes sense for a different type of user, and the wrong pick will either leave you frustrated with underpowered hardware or paying for capabilities you will never use.

Pydantic v3 shipped in late 2025. It has a new Rust-backed core and a fresh model system. With FastAPI 0.115+, you get auto request checks, fast JSON output, and OpenAPI 3.1 docs. No manual schema work. Data errors get caught at the API edge. Client SDKs come from the live spec. The check overhead that used to be a bottleneck is now mostly gone.

This guide walks through what changed in v3, how to lay out a production project, the validation patterns to know, and what deployment looks like when you care about speed.

Hardening a Docker image means cutting the attack surface at every layer. Start from a minimal base like distroless or Alpine. Run as a non-root user. Set the filesystem read-only. Drop all Linux capabilities and add back only what the app needs. Pin dependency versions with checksums. Scan images with Trivy or Grype before you push. Each layer of this checklist stands on its own, so you can adopt them one at a time.
