Hello, World

Why a blog#

When running experiments, a lot of ideas and pitfalls only live in terminal output and scattered notes, and a few weeks later they’re gone. Writing things up forces me to think them through, and makes them easy to find again.

How this blog is built#

• Generator: Hugo — posts are Markdown, output is plain static HTML
• Hosting: Cloudflare Pages, rebuilt and published automatically on every push to GitHub
• Theme: a small hand-written theme with bilingual support and dark mode

A quick formatting test#

Inline code python train.py --seed 0, and a code block:

import torch

def rollout(model, obs, horizon=16):
    """Roll the world model forward `horizon` steps in imagination."""
    states = []
    for _ in range(horizon):
        obs = model(obs)
        states.append(obs)
    return torch.stack(states)

Math works too. Inline $p(s_{t+1} \mid s_t, a_t)$, and display:

Make it work, then make it good.
