Hello, world

This is the first post. Posts are plain Markdown files in site/src/content/posts/. The block at the top (the frontmatter) sets the title, date, tags and description.

How it’s built

Every page on this site is static HTML generated by Astro and served from an S3 bucket through CloudFront. Slides are built with Slidev and live under /talks. For example, the deck Building this blog walks through the setup.

Tip

Set draft: true in the frontmatter to keep a post out of the production build.

Code

const distribution = new cloudfront.Distribution(this, "Cdn", {
  defaultBehavior: {
    origin: origins.S3BucketOrigin.withOriginAccessControl(bucket),
  },
});infrastructure/lib/site-stack.ts

Maths

Inline maths works with single dollars, e.g. $e^{i\pi} + 1 = 0$ . Display maths uses double dollars:

\operatorname{softmax}(z)_i = \frac{e^{z_i}}{\sum_{j=1}^{K} e^{z_j}}
