Which new rules on my topic are coming in Japan or the US, and when can I still comment?. One finished brief per topic: Japanese e-Gov public-comment drafts still open, US Federal Register proposed rules with open comment windows, US final rules and Japanese law amendments published but not yet in force, and recent Japanese comment results with the number of comments received. Plain English or Japanese keywords (drone, AI, food labeling, tax, 建築, 医薬品). Deadlines, days left, counts and topic matching computed by Lilambd from official registers; every item links to its official page. Japanese titles stay in Japanese; US items carry title_en. Facts only, not legal advice. Routes: /answer (topic*, country, limit, routine); /topics (country, limit); /upcoming (country, status, topic, kind, stage, agency, category, since, until, sort, limit, offset).

Lilambd World Signals Daily Change by Country. What changed today in the world's news events, per country. Daily GDELT 2.0 event counts by country and CAMEO root code (20 event types from public statement to mass violence) with mean Goldstein score, collected every morning since 2026-09-22: 19,185 country x event-type rows covering 126,256 events in 228 GDELT country codes over 31 collected days (2026-09-22 to 2026-11-03; 12 days not collected). One call to /today/{iso2} returns today's totals for a country against the previous collected day and the 7-day baseline, its rank, conflict share and the biggest changes by event type. Also: rankings, rising country x event pairs, time series per country. Source: Lilambd/world-signals (CC BY 4.0), GDELT Project (free with attribution).

How do these cities really compare: size, density, growth, greenery, roads, climate and access?. Side-by-side brief for up to 4 of 6,902 cities (every city with 100k+ people, 176 countries). Each city is measured three ways so comparisons are fair: the continuous built-up agglomeration seen from space (EU GHSL), a fixed 10 km disc, and the OSM administrative polygon. Population 2000 and 2025, density, built-up share, built-area greenness, centre-3 km road/rail/foot-path length and park share (OpenStreetMap via Overture), elevation and relief, 1991-2020 temperature and rainfall measured at the nearest NOAA GHCN station (never model-filled), nearest large airport (IATA) and seaport with km. Every metric also comes as a percentile among all 6,902 cities. Sources and data dates in the attribution. Facts only. Routes: /answer (cities*); /search (q*); /coverage.
