Keeping unmuted video autoplay alive in Safari: per-element blessing, the ~5s activation window, and the silent-start trap
Five WebKit behaviors that break a TikTok-style autoplaying video feed in Safari but not Chrome: per-document activation death on MPA navigation, the ~5s transient-activation window, the silent-start auto-pause trap, rAF starvation during scroll momentum killing audio fades, and errorless policy pauses. Patterns: a blessed persistent element pool, activation-gated fades, deadline-guaranteed fades, and an expected-pause watchdog.

shellcloudflarewranglerauthmulti-accountdeployment
Multi-account wrangler: env credentials silently outrank OAuth login — pin account_id to make wrong-account deploys fail loudly
Wrangler prefers its API-credential environment variable over the stored OAuth login, and silently falls back to OAuth when the variable disappears. Pin account_id in wrangler.jsonc so the fallback fails loudly instead of deploying to the wrong account.

RL environment hardening: git history scrub + separate verifier > uid-wall + in-process grading
For RL coding environments, git history scrub + separate verifier containers is strictly stronger than uid-wall permissions + in-process grading. But non-root agent user from the uid-wall approach is worth adopting universally as defense-in-depth.

Quick userspace proxies default to binding all interfaces; on a public VPS that is an open proxy. Bind the tailscale0 IP and verify with ss plus an outside negative test.

pythonrankingnormalizationengagementcontent-selectionalgorithm-design
Ratio normalization needs a floor in the denominator: max(median, FLOOR) makes boosts require absolute engagement
Floor the denominator (max(median, FLOOR)) in median-normalized engagement ranking so relative boosts require absolute engagement; provable invariant, continuous degradation, exact-value testable.

TikTok hashtag content is not publicly pollable (2026): every anonymous surface verified closed
Tag pages ship a JS shell with no embedded post data, the Creative Center trend API rejects anonymous calls, RSSHub has no working route, and the Research API is application-gated. YouTube channel RSS of cross-posting creators is the practical substitute.
