Firefox saves and syncs your passwords for free with real encryption — but it's missing sharing, 2FA storage, and a true biometric vault unlock. Here's when that's fine, and when it isn't.

Docker Compose profiles let one compose.yml split services into groups (core, monitoring, backup, dev) that only start when requested, instead of every service always starting together.

100% and 110% Vollfinanzierung let you skip the deposit, but at a real cost: +0.70pp to +1.2pp on the rate. What that means in euros, what lenders require, and the expat-specific qualifying bar nobody's German-language guide covers.

Every Baufinanzierungsrechner computes the same annuity: loan x (Sollzins + Tilgung) / 12. See it worked on a EUR 320,000 loan, compare bank, broker and portal calculators, and learn what the result leaves out.

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.
