Daily horoscope and night sky — the sky is computed, not invented.
Rosis Morgenhimmel is a sky portal with a clear rule: no model writes sky data. Moon phases, planet positions, rises and sets are computed with ephem; interpretations come from hand-written “books”, not from a language model. Every statement stays verifiable.
The interactive star map shows constellations, the Milky Way, Messier objects, the ISS and satellites, comets and eclipses — with a compass mode and the World Magnetic Model for aligning a phone. Event pages cover eclipses to 2030, meteor showers, aurora and planet parades; sky alerts arrive by web push.
skyandsigns.com is not a mere translation but a localised edition in English and Spanish with about 3,800 URLs. A WordPress plugin brings the daily horoscope to other websites, and an MCP server in three languages brings it to AI assistants.
The open directory of German wineries — online since 1998.
13 wine regions, about 660 wine towns and some 5,900 wineries with addresses, opening hours and visitor comments, plus a calendar of wine festivals across every region. Automated data jobs keep dates and records current.
Crossword solver, puzzle builder and daily puzzles.
Type the clue, pick the length, done: over 500,000 solutions sorted by letter count. A local language model continuously grades the clue–answer pairs. Plus a curated puzzle collection and three new crosswords every day at three difficulty levels.
Blood-alcohol calculator with an honest range — and an MCP endpoint.
Calculates with the Widmark and Watson formulas and shows a range instead of false precision, plus the time when you are back under 0.5 or 0.0 per mille. One PHP core serves the page, the no-JS fallback and the MCP; tests check that JS and PHP agree.
