AWS_SECRET_KEY=supersecretpassword123 committed to a public GitHub repo. We've all seen it. Vault is the tool that makes hardcoded secrets unnecessary — KV storage, dynamic credentials, PKI, and AppRole auth, all accessible via API. Here's how to actually run it.

Linux ships with conservative kernel defaults meant for general use. These sysctl settings tune your server for networking, memory, and file I/O — with explanations, not just values to paste.

Authelia is a bouncer. Authentik is the whole security desk. Pick the right self-hosted SSO for your home lab — with working configs, gotchas, and a migration path.

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 already faster than OpenVPN and IPsec out of the box — but default config leaves real throughput on the table. MTU misconfiguration alone can cost you 30% of your bandwidth. Here's how to tune WireGuard properly, measure what you actually get, and understand why the numbers are what they are.

ELK does everything and wants all your memory. Loki does logging the Prometheus way — label indexes, not content — and runs on a fraction of the resources. Here's the honest comparison.

Cockpit is the modern systemd-native Linux admin panel. Webmin is the veteran that configures everything. Here's which one should be on your servers — and which shouldn't.

Every website you visit starts with a DNS query, and by default that query goes out in plain text so your ISP, your coffee shop's router, and anyone in between can log exactly what you're looking at.
