• To get images, rename the pptx to .zip¹ and just copy them from the archive
  • zipinfo lists everything

• ssine/pptx2md: a pptx to markdown converter does this automatically!

  • --qmd
  • Had to install deps manually
  • In LibreOffice could delete the footer and header in the master slide, giving me clean slides.
    • LibreOffice could delete header only, but not the footer — had to use MS Office for this

• // Ha: [Falk358/quarto_translator: A python project for translating quarto markdown files using the openai API](https://github.com/Falk358/quarto_translator+

  • Tested it on a small file, it actually works nicely

LaTeX

Colorful equations

How do I write LaTeX with colors in quarto presentations? · quarto-dev/quarto-cli · Discussion #4429

$$\begin{aligned}
\color{green}{\bf{Net Benefit}} = \frac{\color{green}{\bf{TP}}}{\text{N}} - \frac{\color{red}{\bf{FP}}}{\text{N}} * {\frac{{p_{t}}}{{1 - p_{t}}}}
\end{aligned}$$

$$\color{red}{w_0} + x_1*w_1 + x_2*w_2 + x_1*w_1$$  

It uses the usual names: LaTeX Color Definitions

Actually² these: MathJax-src/ts/input/tex/color/ColorConstants.ts at master · mathjax/MathJax-src

HA, it can even do usual RGB hex colors!

The useful to me are Cardinal/Carmine and Cerulean/Blue?..

Size of formulas

Quarto align stuff right

Quarto: How to right justify text in PDF and HTML - Stack Overflow:

\`\`\`{=html}
<style>
.flushright {
   text-align: right;
}
</style>

::: {.flushright}

But actually,

::: {style="text-align: right;"}
$\small{E(W) = \frac{1}{n} \sum_{i=1}^{n} \mathcal{L} \left( \color{blue}{f(x^{(i)}; W)}, \color{red}{y_{true}^{(i)}} \right)}$

Height and aspect ratios

Preview in a long/high browser window to see what the actual width of the presentation is. PDF export also uses the actual width

Misc

• ✕ aka MULTIPLICATION X is a really nice cross mark to use in random pictures.³
  • \times in latex
• ⮕ is a good arrow.
  • → is better (→)
