Welcome to the Tech Notes

This is the first entry in the Data Science & AI section. Everything you need to publish a new one is a markdown file dropped into the _tech/ folder.

How posts work

Each file starts with a small block of YAML at the very top — the front matter — that powers the cards on the home page:

---
title: "Your title"
description: "One line that shows under the title."
date: 2026-06-05
---

Below that, write normal markdown. Inline code like np.mean(x) is styled, and fenced code blocks get syntax highlighting:

import numpy as np

def softmax(x):
    e = np.exp(x - x.max())
    return e / e.sum()

That’s it. Save, push, and GitHub rebuilds the site for you.
