Hello, World

Welcome to KingRolo.com. This is the first post, and it doubles as a showcase of what this blog can do — now rebuilt on Astro.

Code

The whole point of a technical blog is showing code. Here’s some Python:

def fibonacci(n: int) -> list[int]:
    """Generate the first n Fibonacci numbers."""
    if n <= 0:
        return []

    sequence = [0, 1]
    while len(sequence) < n:
        sequence.append(sequence[-1] + sequence[-2])
    return sequence[:n]

if __name__ == "__main__":
    print(fibonacci(10))  # → [0, 1, 1, 2, 3, 5, 8, 13, 21, 34]

Sometimes you want a plain block with no filename header:

uv run python scripts/smoke_test.py

And the same idea in two languages (proper interactive tabs land in the next pass — for now, side by side):

def fibonacci(n):
    a, b = 0, 1
    for _ in range(n):
        yield a
        a, b = b, a + b

fn fibonacci(n: usize) -> Vec<u64> {
    let mut seq = vec![0, 1];
    for i in 2..n {
        seq.push(seq[i - 1] + seq[i - 2]);
    }
    seq.truncate(n);
    seq
}

Inline code looks like this: print("hello").

Admonitions

Blockquotes

The best way to predict the future is to invent it. — Alan Kay

Blockquotes can also contain other markdown elements:

Pro tip: When designing a system, write the README first.

If you can’t explain it simply, the design is too complex.

Lists and Formatting

Things I care about:

• Clean typography
• Fast page loads
• Schema-typed posts
• Perfection (work in progress)

Some formatting options: bold, italic, strikethrough, highlighted, and inline code.

What’s Next

This blog is a work in progress¹. More posts to come on systems design, Python tooling, and whatever else catches my attention.

Thanks for reading.
