- 11 NUL bytes in generated code: source files that compile, lint, and run — but are invisible to grep, VS Code search, and code review A raw NUL byte inside a string literal leaves a TypeScript file valid to tsc, node, ESLint and Prettier, and invisible to ripgrep, VS Code search, and git diff — measured on each. The key-format bug that hid behind it, how a JSON tool call writes the byte, and the two fixes that need no vigilance. artificial-intelligence · debugging · 10 min

Duplicate script ID - 09 Why captured subtitles don't line up: X-TIMESTAMP-MAP, stitched timelines, and four other causes Six reasons a correctly parsed subtitle track still lands in the wrong place in a browser video player, each with the symptom that identifies it: absolute MPEG-TS baselines, content versus presentation time, presentation time offsets, lazy fetching, per-URL clobbering, and arrival order. captions · video-streaming · 6 min

- 05 [Emdash] How an Unchecked Empty Submit and a Falsy-ID Guard in convertPTBlock Created a Permanent Autosave-Erasure Loop for YouTube Embeds An unchecked form submission in EmDash's PluginBlockModal inserts YouTube blocks with empty IDs, which a falsy check in convertPTBlock converts to placeholder text on reload — and autosave permanently overwrites the original data two seconds later. The patch removes the falsy guard from the serializer and adds a form validation check to the modal. emdash · cms · 2 min
{ "_type": "youtube", "_key": "abc123", "id": "https://youtube.com/watch?v=..." } - 04 [EmDash] A Vitest Regression Guard for publicHoistPattern and ssr.optimizeDeps.include on Cloudflare Workers A Vitest test that verifies every package in ssr.optimizeDeps.include is both hoisted to node_modules/ and resolvable — so a missing publicHoistPattern entry surfaces as a named, actionable test failure instead of exports is not defined deep inside a workerd stack trace. vite · astro · 2 min
// src/lib/ssr-deps.test.ts import { existsSync } from "node:fs"; import { createRequire } from "node:module"; import { join } from "node:path"; import { describe, expect, it } from "vitest"; - 03 [EmDash] Why @atproto/api Caused exports is not defined in workerd and How pnpm Hoisting + ssr.optimizeDeps.include Fixes It @atproto/api is CJS and lives only in pnpm's content-addressable store, so Vite's SSR optimizer can't find or convert it — meaning raw CJS reaches Cloudflare workerd, which has no exports global, and crashes. The fix requires both hoisting the package via publicHoistPattern and listing it in ssr.optimizeDeps.include. vite · astro · 2 min
Error: exports is not defined at runInRunnerObject (workers/runner-worker/index.js:107:3) - 02 [EmDash] Note `ssr.optimizeDeps.include` Fixes Vite 7's SSR Dep Optimizer Race Condition and Stale Chunk Crashes on Cloudflare Workers Vite 7 separates SSR and client dep optimization, and packages discovered lazily at request time trigger re-optimization rounds that invalidate shared chunks mid-request. The fix is `ssr.optimizeDeps.include` to pre-bundle all CMS sub-paths at startup before any request arrives.
