+ Hello, world!
+</p>
+<p>
+ This is the first test of my simple, static blogging system. My goal is to avoid using anything too heavy and, instead, provide a simple script that will get run whenever I update a blog post. Heck, I could even set it up to a cronjob to refresh them everyday. But perhaps that is overkill for today 😆. I am satisfied with how it current works.
+</p>
+<p>
+ Expect to see some updates on Greek philosophy, emacs, and Linux coming soon to a website near you!

-<h2>Linear Systems Solver</h2>
-<h3>2021-08-01 by Matthew Kosarek</h3>
-<p>
- I wanted to write a little algorithm to visually solve linear systems of equations for fun. I am only going to deal with 3x3 matrices for now, but I'll make it so that I can easily extend it to more matrices in the future if I think that would be cool.
