Hello World: A Sample Post

Testing the theme with all its features

February 28, 2026 — meta, test

This is a sample post to demonstrate the theme’s typography and features. The body text is set in EB Garamond, a revival of Claude Garamont’s sixteenth-century typefaces — elegant, readable, and well suited to long-form writing on the web.

Sidenotes

Tufte CSS provides sidenotes as an alternative to footnotes. This is a sidenote. On wide screens it appears in the margin; on narrow screens, tap the number to reveal it inline. They allow the reader to glance at supplementary information without losing their place in the main text.

Margin notes

These are sidenotes without numbers. This is a margin note. Notice it lacks a number — it provides context rather than citation. They work well for brief asides, definitions, or contextual information.

Code

Inline code uses JetBrains Mono: fn main() { println!("hello"); }.

A code block:

def fibonacci(n: int) -> int:
    """Compute the n-th Fibonacci number."""
    if n <= 1:
        return n
    a, b = 0, 1
    for _ in range(2, n + 1):
        a, b = b, a + b
    return b

Mathematics

KaTeX renders math inline like $e^{i\pi} + 1 = 0$ and in display mode:

$$ \int_{-\infty}^{\infty} e^{-x^2} \, dx = \sqrt{\pi} $$

The Cauchy–Schwarz inequality:

$$ \left( \sum_{k=1}^{n} a_k b_k \right)^2 \leq \left( \sum_{k=1}^{n} a_k^2 \right) \left( \sum_{k=1}^{n} b_k^2 \right) $$

Block quotes

The purpose of computing is insight, not numbers.

Richard Hamming

Lists

Some things worth reading:

  • Gwern’s writings on spaced repetition
  • Bartosz Ciechanowski’s interactive explanations
  • Anything by Edward Tufte

New thought

In his later work, Tufte advocated for information-dense graphics that respect the reader’s intelligence. This paragraph demonstrates the newthought small-caps opener used to signal a shift in topic without a full section heading.
