Album data comes from the Spotify API. Reviews, ratings and follows live in MongoDB, and a WebSocket channel pushes new activity from people you follow into your feed without a refresh.

Typesetting Math and Code on This Site

Sat, 12 Sep 2026 00:00:00 -0600

Posts here can use LaTeX directly in markdown. Inline math like $e^{i\pi} + 1 = 0$ sits in the line, and display math gets its own block:

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

Everything is rendered to HTML when the site builds, so there is no JavaScript involved and nothing flashes on load. Here is a matrix, because why not:

A = \begin{bmatrix} 1 & 2 \\ 3 & 4 \end{bmatrix}, \qquad \det A = -2

Code

Code blocks are highlighted at build time too.

Running a Website on a Free ARM Server

Oracle’s Always Free tier halved its Ampere A1 allocation in June — four cores and 24 GB became two cores and 12 GB. Still the most generous free tier anyone offers, and enough to run a genuine pile of things.

This is the first post. More to come.

About

Mon, 01 Jan 0001 00:00:00 +0000

I’m Gabe Yocum, an applied and computational mathematics student at BYU. I spend most of my time building automation systems: workflows, data pipelines and agents that take tedious work off people’s plates.

On the side I ship a steady stream of projects, like a music review network and an iOS app making its way to the web. They run on a single free ARM server, which I wrote about.

I like problems where the math and the engineering meet. If you have one of those, or just want to talk shop, my inbox is open.
