The YuE2 and subtitles posts shipped text-only: render_from_art.mjs only READS
ogImage/banner, and after the 2026-10-19 bulk migration no script had to write
them, so both pages advertised /og-default.jpg and rendered no hero banner.
- new metaphors (in build_captions.py, frozen here via sync_prompts_catalog.py),
captions, art-meta evidence, banner plan and the five derived files per slug
- frontmatter: ogImage + banner in EN and ZH for both posts
- scripts/check-assets.mjs is now step 1 of npm run build, so CI fails when a
published post lacks a language-correct og card, banner, banner .webp or
400/800 list thumb. It reported 16 problems on the unfixed tree, all here.
The ::before used CSS escapes written through a Python string, which ate them
(octal escape) and shipped control bytes — the button read as mojibake.
- use a literal UTF-8 arrow instead of \2193\0020
- figcaption is now flex, so a long title wraps under the button rather than
being crowded by a float; verified at 360px and 680px
- round the shown duration down so it matches the player's clock (197 s = 3:17)
Tutorial on turning untimed AI-generated audio into LRC + SRT: align ASR word
timestamps against the KNOWN lyrics (SequenceMatcher) instead of trusting a
transcript, then a governor that rejects impossible anchors, refills runs by
unit-proportional duration, and enforces a 1.2 s minimum line gap.
Ships 18 English songs (342 subtitle lines, mean anchor coverage 0.96, 9/18
fully anchored) with synced lyrics plus downloadable .srt per track. Documents
both player bugs and the headless-Chrome numeric probe that finally caught them.
offsetTop is measured from the nearest positioned ancestor, so inside an
unpositioned .yue2-box it returned the line's distance from the page top
(thousands of px). scrollTop clamped that to maxScroll, so the box jumped to the
bottom the moment singing started and the text was unreadable.
Now: box.scrollTop += (pr.top - br.top) - (clientHeight - lineHeight)/2, plus
position:relative on the box. Verified in headless Chrome with a numeric probe:
the active line sits ~124px into a 274px box at t=48/100, nothing is highlighted
and scrollTop=0 at t=0, and the box settles at maxScroll only for the final lines.
findIndex(t > now) - 1 returned -1 before the first line started, which the
`if (i < 0) i = lines.length - 1` guard turned into the LAST line — so playback
began scrolled to the bottom. Use a last-passed-index scan instead (-1 = before
the first line), centre the active line inside the box (so upcoming lyrics are
visible), and scroll the box itself rather than scrollIntoView(), which dragged
the whole page. Also bumps the box to 250px. Fixes yue2 post + both Suno posts.
Twelve Mandarin songs came back exactly 240.000 s with the outros cut.
Documents the ffprobe tell, the BPM myth, the seed-cache trap, the
2.0-2.8 hanzi/s spread, the 300 s VRAM ceiling, and the archive-the-clipped
policy. Ships 11 finished tracks with ASR-derived synced lyrics (EN + ZH).
The card renderer already normalises straight quotes to “ ”, but the post H1 and the HTML
<title> were still printing an escaped straight quote (). The two ZH posts that use
quoted phrases now carry the curly characters in the frontmatter itself, so the article page
matches the card.
Every post now carries one unique local-ComfyUI/Ideogram 4 base frame, composited
into EN + ZH share cards, a banner and list thumbs.
- the shipped prompts_catalog held only 21 distinct metaphors for 72 posts (16
shared one visual), so all 72 were rewritten as unique object+state metaphors
and 10 frames re-rolled after OCR found pseudo-text rendered at legible size
- render_from_art.mjs emits JPEG by default (558 KB PNG -> 84 KB mozjpeg q85);
the ZH 1200x630 card did not exist before this batch
- 288 frontmatter fields migrated; the 144 v1 PNGs are gone
- PostList's thumb helper keys off the base slug (a ZH card is zh-<slug>.jpg while
the thumb is <slug>-800.webp, which 404'd the whole ZH listing)
- [...slug].astro's <picture> regex accepts .jpg
- the repo now carries the art inputs (metaphors.json, captions/<slug>.json,
refreshed prompts_catalog.json) so a frame is reproducible from git alone
The commit-churn post the owner read and approved today, published in the
first-person voice he asked for.
- Voice rewrite before publishing: the draft opened on "when managers or
recruiters ask how productive an engineer is" and addressed the reader in the
second person throughout (you/your 12 -> 2, both in the CTA; ZH 你 5 -> 2).
It now reads as a log entry: "Last week I did something I almost never bother
to do: I counted my own commits." Headings moved from essay titles to actions.
Numbers, the 5-repo table and every claim are unchanged.
- Title changed at the owner's request:
"Why 500,000 Lines of Commit Churn Only Left 230,000 Lines in Production"
-> "I Committed 518,000 Lines in 30 Days. Production Kept 235,000."
(ZH: 30 天提交 51.8 万行，生产环境只留下 23.5 万行), pubDate 2026-10-18.
- Fixed two real defects found while making the card: the draft claimed "four
automated gates" and listed three; and og-gen split titles at the word-count
midpoint, breaking at "…Lines in / 30 Days" — the splitter now prefers a
sentence boundary near the middle and falls back to the midpoint.
- og PNG regenerated for the new title, thumbs and banner WebP re-derived.
Measured: card 2 title lines, overflowY 0, measure_og_banner PASS (tags 1 row,
banner delta 2), build clean, /posts/ monotonic with this post on top.
Also queued the post at the head of the dev.to drip (queue 69 -> 70).
- my-backup-was-using-someone-elses-api-quota (notes, 2026-10-15, pinned by its own evidence)
- space-reclamation-wasnt-stuck-it-was-waiting (devops, 2026-10-14, pinned by its own samples)
- adding-a-domain-to-someone-elses-mail-server (notes, 2025-05-06, backdated: no date/version pins)
- embedding-fonts-so-a-pdf-looks-the-same-everywhere (engineering, 2025-01-22, backdated: no date/version pins)
All four updatedDate 2026-10-16 so every lastmod stays honest; the two backdated posts carry no prose links
(a backdated post may only link backwards). og measured rows=1/overflow=0, banners 8 rows/delta=2/overflow=0.
Backdated into the 2025-02 gap: pubDate 2025-02-20, updatedDate 2026-10-16 (lastmod honest).
No calendar dates or checkable version pins in the prose — the condition for backdating — and
no internal links, since every post it would cite is dated later and a backdated post may only
link backwards (see project-state B2n). Generators: additive entries only (5 + 17 lines, 0 deletions).
- calibrating-intel-quick-sync-hevc-quality (tutorials): pubDate 2026-10-14, updatedDate 2026-10-16
(its real work date; sitemap lastmod stays honest). ffmpeg 9.0.2 pins it to 2026-09-18 at the earliest,
so it cannot be backdated — see project-state B2l.
- docker-reported-exit-0-the-oom-killer-disagreed (devops): pubDate 2026-10-16, date-pinned by its own
dmesg table, ships on the real date.
- og measured rows=1/overflow=0, banners delta=2/overflow=0 on both; build 159 pages, no warnings.
- git rm src/content/posts/the-dialog-opened-in-7-seconds-my-script-waited-5.md + the zh twin
- drop its TERMINALS/BANNERS entries from both generators (pure deletions: 0 added, 17 + 5 removed,
node --check OK, 0 remaining references to the slug, the other three slugs intact)
- build still 153 pages; no route, no listing row, no sitemap entry
Written 2026-10-16 from the linkedin-daily-post session, then dropped by the user.
Kept as draft:true rather than deleted so the text is version-controlled and a
flip of one flag can publish it later. draft:true excludes it from the build
(153 pages vs 155), the listings and the sitemap — verified. Its OG/banner PNGs
were deleted (drafts in this repo ship without images); BANNERS/TERMINALS entries
for the slug are already committed, so regeneration is one command.
- draft: true -> false in both files, pubDate 2026-09-20 kept, updatedDate 2026-10-16 (lastmod honest)
- fix the CTA's displayed phone number (011-797 2969 -> +60 12-797 2969)
- generate public/og + public/banners for the slug (og rows=1 overflow=0; banner delta=2 overflow=0)
- generators carry the TERMINALS/BANNERS entries for this post; three more entries for
posts written the same session (held for review, not committed here) are inert
Measured on real files with quality held fixed (SSIM vs the source, harness self-tested at 1.0000):
hevc_nvenc cq27 produced 115% and 119% of the source video bitrate on two of three files while cq30/31
landed 51-84%; libx265 crf26 landed 33.7/56.7/67.0% at min SSIM 0.988-0.993, i.e. 10-22% smaller than
NVENC at matched quality. Two sources with identical bpp (0.0437) shrank 49% vs 17%, so bpp classifies
files but does not predict the ratio. Notes the audio floor (a 33.7% video stream still yields a 53%
file because AAC dominates what is left) and why VP9/AV1 sources have no headroom (copy the video).
Three silent failures on a network-mounted share: a 403 MB upload that wrote 12.5 MB and returned OK
(the timeout toast arrived minutes later, asynchronously), an os.replace() that never landed while
getsize()/mtime served cached metadata (the destination was still the original H.264 file), and a
byte-count source check that agreed with a length-preserving bad copy. Adds read-back hashing at all
three boundaries (source copy, upload, install) and records the metric traps that hid them: a clean
decode test on wrong pictures, SSIM on near-flat frames, input-seek decoding of open-GOP sources,
stream-copy slices dropping frames, and fixed-name scratch files colliding across concurrent runs.
Audit after the fix: reported=30 landed=29 not-landed=0.
The converted HEVC stuttered in VLC, Chrome and on an iPad (offline) while the source played fine.
Container timing was perfect (5818/5818 frame intervals at exactly 0.040000 s, no dup/backward PTS,
ctts not flat) and a full decode printed nothing. Cross-decoder SSIM found the real defect: NVDEC's
legacy av1_cuvid wrapper returns frames from the wrong timestamps - 106 of 5819 frames, SSIM down to
0.330, deterministically, roughly every 30 frames - and the HEVC output was a faithful encode of those
wrong pictures (min 0.991 against the NVDEC decode, min 0.330 against a software decode). Fix is one
line (-hwaccel cuda -hwaccel_output_format cuda -c:v av1, verified 1.000000 over 1500 frames; vp9_cuvid
unaffected). Adds the content gate (structure AND pictures, defect-shaped thresholds) to the pipeline.
Re-checked against the actual repo rather than the API summary: the old branch
survives as a single commit whose README is the word 'deleted', and it shares no
common ancestor with main's 233 commits. Sharper and fully verifiable, EN+ZH.
1) the-upstream-was-deleted-then-came-back-rewritten (devops, pubDate 2026-10-06)
docker pull hectorqin/reader -> 404; the repo was re-initialised 2026-09-16 and now
carries 233 commits, a TypeScript/Node rewrite, port 5888, SQLite /data, config moved
into the admin UI, and an image on cnb.cool with no tags or releases. Covers telling
dead from rewriting, the migration boundary, and keeping the front door outside the
app image. Facts re-verified live 2026-10-06.
2) putting-a-front-door-on-an-app-you-cant-modify (devops, pubDate 2025-06-24 backdated
into the empty 2025-06 window, updatedDate 2026-10-06 so lastmod stays honest)
The reader-gateway pattern: a second nginx container owning the public port, the
request-time resolver, why a proxy body rewrite cannot touch a client-rendered SPA,
the gate-bounce injection with its pass token, the app's own CSS hook for branding,
and the silent-failure check to run after every app upgrade.
Both: EN + ZH twins, TERMINALS/BANNERS entries appended via append_generator_entries.py
(additive, deletions 0, node --check OK), og/banner generated and measured PASS
(og rows=1 overflow=0 missingHash=0; banner 8 rows, delta 2, overflow 0).
The Phase C1 keystone asset (Story B). Publishes the infra case study:
- architecture: 3 hosts / 162 containers / 78 compose stacks with the per-host split
- incident record: the monitoring panels that lied, and the Passbolt cascade
- how the numbers are re-derived (verify_infra.py) rather than remembered
- no uptime percentage: availability is not measured, so the post says 'monitored'
- hire CTA (case-study convention)
EN + ZH twins, og + banner generated and measured (OG 5 tags/1 row, banner 8 lines delta 2).
Phase C1 keystone (Story B). Draft, not published: draft: true.
- architecture: 3 hosts / 162 containers / 78 stacks, per-host split (86/44, 37/21, 39/13)
- ingress (Traefik + ACME), identity (authentik), monitoring (single Grafana), CI/CD, backups
- incident record: the monitoring panels that lied, and the Passbolt cascade (one missing
config value, three failure modes) — both link to their deep-dive posts
- numbers are re-derivable via verify_infra.py rather than remembered
- NO uptime percentage: availability is not measured anywhere (no probe-based monitor
deployed), so the post says "monitored", not a figure
- DO_NOT_PUBLISH services excluded entirely
EN only + no og/banner yet: not publishable until the ZH twin and images exist and the
owner approves. Local commit only — not pushed.
Five posts with custom OG + banner and hire CTAs. Three are web3, giving
that category its first posts — /categories/web3/ previously 404'd while the
index advertised it as '0 posts - coming soon'.
Backdated where the work genuinely is older: the foundry-nft and
hardhat-smartcontract-lottery commits date to 2024-08-15..19, so those two
posts fill the empty 2024-10 and 2024-12 archive months with updatedDate
holding the real date. The two 2026-08-19 posts use their real work date.
TERMINALS/BANNERS entries for all five slugs are committed this time (both
generators were clean; diffs verified purely additive).
Backdated into the empty 2025 stretch of the archive (pubDate 2025-07-08 / 2025-03-19)
with the real date kept in updatedDate 2026-09-29 so sitemap lastmod stays honest.
Custom OG + banner for both; no date- or version-pinned prose in either post.
Backdated into the 2026-03-25 -> 2026-09-04 archive gap (pubDate 2026-04-14/05-17/06-24/07-29)
with updatedDate 2026-09-29 holding the real date, so sitemap lastmod stays honest.
Custom OG + banner per post, hire CTA, language switch verified.
- docker/Chrome/CDP gotcha: the container kills the browser, so it never exits
cleanly and no restore mechanism fires (flag, Preferences, managed policy all
verified failing) -> 60s snapshot + replay keeper
- also covers the stale Singleton* lock and custom-cont-init.d permission traps
- custom OG + banner art, EN + ZH, backlog B2 updated
New `devops` post on vetting an upstream dependency before building on it:
the six checks that corrected six assumptions from a 1,306-line architecture
spec — repo vital signs via the GitHub API, grepping for the feature instead
of reading for it (OIDC/SSO/SAML → 0 hits), reading a feature doc's target
branch (white-label lives on `multi-tenant`, not `main`), reading the data
model rather than the feature list (percent/fixed vs five assumed rule types),
the Community-vs-Enterprise tier gate (API tokens free, SSO paid), and whether
the money rail works in-country (selfhost + manual payouts, not Stripe Connect).
Closes with the fallback question and the authentik proxy-provider answer.
- EN: src/content/posts/vetting-an-open-source-dependency-before-you-bet-on-it.md
- ZH: src/content/posts/zh/<same slug>.md (same filename → auto language switch)
- Custom OG (1200x630) + banner (1600x900) art via TERMINALS/BANNERS entries
- pubDate 2026-09-29; build verified 93 pages, 17/17 content checks, listing
order monotonic on /posts/, / and /zh/
Note: the generator maps also carry two entries belonging to parallel
in-flight posts (adding-english-mode…, and the sessions' other slugs);
their post files were left uncommitted.
- migrating-codeigniter-iis-to-openlitespeed (engineering): the two fatal errors
IIS + SSO had been hiding (env() called from Constants.php; parent::__construct
in a controller) — both only surfaced on the first unauthenticated request
- upgrading-codeigniter-46-to-47 (notes): the two undefined config properties the
official upgrade guide cannot warn about (Config\App::$permittedURIChars,
Config\Format::$jsonEncodeDepth)
- both flipped draft:true -> false, pubDate 2026-09-20 -> 2026-09-27 (real publish date)
- generated 1200x630 OG cards + 1600x900 banners for both slugs
- verified before commit: EN+ZH pages build, language switch links both ways,
listing order stays monotonic on /posts, /zh and the homepage, banner terminal
panel centred (gapAbove 102 / gapBelow 104) with no overflow
