Turn the first page of a paper (arXiv or any PDF) into a slide-ready PNG for a colloquium deck's 30-40% right column. Use when a slide cites a landmark paper and a screenshot of the paper itself is the best visual.

Render the first page of a paper as a PNG for slides. A full paper page is
portrait (~1:1.27), which is exactly the right shape for a columns: 62/38
right column — prefer the full page over cropping to the title/abstract
region unless the slide needs the abstract text to be readable.
Download the PDF (for arXiv, the bare /pdf/<id> URL, no .pdf suffix
needed):
curl -sL "https://arxiv.org/pdf/2112.00861" -o paper.pdf
Convert page 1 to PNG. Density 200 is plenty for a slide column; -trim
removes the page margins and a small white border re-adds clean padding;
PNG8: keeps black-text-on-white pages tiny (~80KB) with no visible loss:
magick -density 200 'paper.pdf[0]' -trim +repage \
-bordercolor white -border 24 -resize x1400 -strip \
PNG8:paper-firstpage.png
Copy the reviewed result into the assets directory the deck uses
(teach/course/assets/ for course lectures, the talk's own assets/
otherwise) with a descriptive name, e.g. hhh-paper-2021.png.
Reference it as a right column with no caption (the page is self-captioning):
<!-- columns: 62/38 -->
## Slide title
Body text... [@citekey]

cp the final PNG in.-trim already keeps it because it is ink.-crop x62%+0+0 -trim after the first -trim +repage.
Only use this when the abstract must be readable on the slide.--screenshot, see the lecture decks' recent
assets for examples.Plan, run, and report a small RLHF Book code experiment.
Extract per-question (MM:SS) timestamps from a recorded course video by OCR-ing the slide counter, then add YouTube deep links to the course page's Q&A question lists. Use after a Q&A or lecture recording is published, or when adding/refreshing "Show questions" timestamp links in book/templates/course.html.
Start or verify live preview for RLHF Book course lecture slides without breaking relative image assets. Use when serving, opening, checking, or debugging `teach/course/lec*.md` slides.
