Code blocks

A short Rust snippet:

fn fibonacci(n: u32) -> u64 {
    let (mut a, mut b) = (0u64, 1u64);
    for _ in 0..n {
        let next = a + b;
        a = b;
        b = next;
    }
    a
}

fn main() {
    for i in 0..10 {
        println!("fib({i}) = {}", fibonacci(i));
    }
}

And the SQL I run more often than I’d like to admit:

SELECT
    table_schema,
    table_name,
    pg_size_pretty(pg_total_relation_size(quote_ident(table_schema) || '.' || quote_ident(table_name))) AS total_size
FROM information_schema.tables
WHERE table_schema NOT IN ('pg_catalog', 'information_schema')
ORDER BY pg_total_relation_size(quote_ident(table_schema) || '.' || quote_ident(table_name)) DESC
LIMIT 20;

Math (KaTeX)

The mass-energy equivalence, inline: $E = mc^2$.

A block equation — the Cauchy–Schwarz inequality:

$$ \left( \sum_{i=1}^{n} a_i b_i \right)^2 \le \left( \sum_{i=1}^{n} a_i^2 \right) \left( \sum_{i=1}^{n} b_i^2 \right) $$

Diagram (Mermaid)

A typical CDC pipeline:
