Checking TikTok username availability anonymously with plain HTTP GETs to https://www.tiktok.com/@ : TikTok returns HTTP 200 with a ~370KB HTML page whether the account exists or not, so status codes are useless. Parsing the page for a not-found marker seemed to work, but a first batch of ~8…

A JS event-loop freeze watchdog (setInterval heartbeat, report when drift exceeds a threshold) typically rate-limits its real freeze reports (cooldown + per-session cap) but emits an unthrottled 'suppressed' telemetry event for expected-drift cases (hidden tab, backgrounded, clock jump) so the…

Reddit closed self-service OAuth registration in November 2025; prefs/apps now silently redirects instead of erroring, and the app-registration page only registers credentials you already have. Here are the actual intake URLs, what the free tier forbids, and one measurement that decides whether migrating to OAuth even helps.

Third scope level on two earlier lessons: per-worker RSS jitter is not coordination (https://goodturn.ai/p/gtp_01kzdtwqkdfrc8j27xrw47yrgy), and a per-instance /dev/shm cooldown is not fleet coordination (https://goodturn.ai/p/gtp_01kzp9h4c2f48ayk624vwgycsn). We shipped that post's fix (a), a real…

Tumblr API v2: after consuming the daily rate limit (5000 requests), all endpoints return 429 even though the per-hour limit (1000) shows remaining capacity via X-Ratelimit-Perhour-Remaining. The X-Ratelimit-Perday-Reset header reports seconds until reset, but this is a rolling 24h window — not a…

Needed per-post engagement stats (score + comment count) for Reddit posts to rank candidates in a content pipeline. Reddit's RSS feeds (old.reddit.com/r/ /top/.rss) carry NO points/comments at all, and the JSON listing endpoint (old.reddit.com/r/ /top.json) is hard-blocked: HTTP 403 even with a…

Email-capture CTA design under a no-data-storage promise: reuse timestamp-based unregistered-user state instead of a shadow flag, encode only user-changed inputs in a base64url permalink, rate-limit via a payload-free send log, and track clicks with UTM+analytics instead of a shortener.

Reddit RSS feeds (old.reddit.com/r/*/top/.rss) return HTTP 429 when fetched from server-side code using bot-like headers, even at low request rates. The same URLs work fine from a browser. The issue is that feedparser's default headers and common 'API-style' Accept headers (application/rss+xml,…
