Compose's 'Up' status only means a process started. Real tuned interval/retries/start_period values across three homelab services, plus wiring depends_on: condition: service_healthy to close the gap.

Home Assistant or Pi-hole goes into a docker-compose.yml, the stack comes up healthy, and device discovery still doesn't work -- no new devices show up. The forum fix is network_mode: host. What it actually does, when it's worth the isolation you give up, and when bridge is still right.

Every Riester calculator online gives you a number with no formula behind it. Here's the actual Grundzulage + Kinderzulage + 4%-Eigenbeitrag math, worked by hand for a single earner and a two-child family.

Riester Rente payouts are 84% taxable in 2026, not tax-free. See worked euro examples for the lifelong annuity and the 30% lump-sum option, sourced to current German tax rules.

Cancelling a Riester Rente counts as schädliche Verwendung and triggers repayment of Zulagen, tax benefits, and taxed growth. See the worked euro cost against three penalty-free alternatives.

Search results for Tailscale scatter across install guides, pricing pages, and comparisons with no map between them. This hub ties all six — what it is, WireGuard internals, install, exit nodes, pricing, and Headscale — into one decision path from a homelab that runs it.

Added a second person to your tailnet and worried a bill is coming? Tailscale's free Personal plan covers 6 users with unlimited devices per user after the April 2026 rework — the real math on what's actually free and when Standard or Premium pays off.

Kfz-Versicherung premiums are up ~10% for 2026. Here's the Nov 30 deadline, the Sonderkündigungsrecht, and how to switch without losing your SF-Klasse.

Tailscale's free tier caps out at 6 users. Headscale, Netbird, ZeroTier, and Twingate compared on real free-tier limits, self-hosting effort, and what switching actually costs.

Hotel wifi doesn't need to see your traffic. Setting up a Tailscale exit node so a phone or laptop routes through home instead — the two-command setup, the DNS-leak toggle most guides skip, and a real cost/speed comparison against a commercial VPN.

A subnet route sat approved in the admin console and still didn't work. The real-world install walkthrough across an Ubuntu server, a Raspberry Pi, and a Proxmox host/LXC — auth flow, MagicDNS, ACL tags, and the two gotchas (LXC's missing /dev/net/tun, the two-step route requirement) that actually cost time.

Tailscale isn't a WireGuard competitor, it's WireGuard with a coordination server, NAT traversal, ACLs, and exit nodes wrapped around it. A first-hand decision framework for when raw WireGuard is enough and when Tailscale's managed layer earns the tradeoff, with sourced pricing and performance figures.
