Hello World

This is a first post to both announce the ability to write something, and to build the infrastructure around it, and to also style it.

Goals

1. To get a reasonable place that I can post thoughts and progress.
2. Learn some frontend and backend development.
3. Be slightly more outwardly focused. Eventually put something of value out there?

Technology

• Node.js hosted on Railway.com.
• Content built using Svelte using Typescript.
• Generally data is held in PostgreSQL with the wonderful PostGIS extension. Reading is using Drizzle
• These posts are raw Markdown as it feeds into my Obsidian obsession. I am reading these into Svelte with Marked and Grey Matter.
• Maps thus far are using MapLibre.

Majority of this is new to me.

Cata.co?

I purchased cata.co many years ago when there was an explosion of nameservers that people were playing with. My thoughts at the time was to create a page called "Catacombs" or "cata.co/mbs". Of course, I never did this but I still really like the shortness and punch of the two syllables Ca-Ta.

Foot-notes

Here is a simple footnote¹. With some additional text after it² and without disrupting the blocks³.

Code block

TypeScript

interface User {
    name: string;
    age: number;
}

async function getUser(id: number): Promise {
    const res = await fetch(`/api/users/${id}`);
    return res.json();
}

Python

def fibonacci(n: int) -> list[int]:
    sequence = [0, 1]
    for i in range(2, n):
        sequence.append(sequence[i-1] + sequence[i-2])
    return sequence

SQL

SELECT city, COUNT(*) as checkins
FROM check_ins
GROUP BY city
ORDER BY checkins DESC;

Math?

Inline math

The quadratic formula is $x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$ which gives the roots.

Block math

$$\int_0^\infty e^{-x^2} dx = \frac{\sqrt{\pi}}{2}$$

Another block

$$E = mc^2$$
