Notes posts are shorter and less finished than writeups. This one exists to show that maths works. Setting math = true in a post’s front matter loads a self-hosted copy of KaTeX for that page only; every other page ships with no script at all.
Inline and display#
Inline maths uses dollar signs: the expected number of probes before a collision is about $\sqrt{\pi n / 2}$ for $n$ buckets. Display maths uses double dollars:
$$ P(\text{escape}) = 1 - \prod_{i=1}^{k} (1 - p_i) $$
When the Markdown parser gets in the way#
Underscores and asterisks inside $…$ are sometimes eaten by the Markdown parser before KaTeX sees them. When that happens, wrap the expression in the math component, which passes the body through untouched:
\[\hat{\theta}_{\text{MLE}} = \arg\max_{\theta} \sum_{i=1}^{n} \log f(x_i \mid \theta)\]
Open questions#
- Where does the policy live, and who can change it?
- What is logged when it is violated, and who reads the log?
