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).
Measured before/after with headless Chrome + CDP (not by eye):
- article banner: <picture> WebP q78 with the PNG as fallback, because the PNG
must stay for og:image (social scrapers do not reliably render WebP cards).
70 banners: 6.02 MB -> 2.52 MB (42%). JPEG measured *larger* than PNG here
(q85 = 129%) — the art is flat terminal-style with sharp text edges.
- post page related cards: dropped four 1200x630 PNGs (183 KB) to display
526x276 where the embedded code is illegible; now text-only cards with a
category badge, date and reading time.
- list thumbnails (home + archive): new /og/thumb/<name>-{400,800}.webp served
via srcset/sizes. Rows display at ~398px but were pulling full 1200x630 PNGs.
Homepage thumbnails ~450 KB -> 62 KB; archive (71 rows) ~3.2 MB -> 436 KB.
- desktop banner capped at 720px centred: 67% -> 45% of a 900px viewport,
keeping the art intact instead of cropping it.
Post page totals: images 277 KB -> 38 KB; page height 5758 -> 5065 (desktop)
and 9423 -> 8807 (mobile). Build: 163 pages.
Script: scripts/optimize-images.py; policy: docs/design-guide.md §3; runbook
step added to docs/ops-runbook.md.
