UmmIt

My personal website and blog — ummit.dev / lamkin.me

About

The source for my personal site: a blog, CTF writeups, and a homepage covering what I work on. It started as a fork of the astro-theme-vitesse template and has drifted a long way from it since.

I forked the theme because the original had stopped getting updates. I keep this copy current and on the latest dependencies, and add features when I need them. If any of it is useful to you, take it.

Tech stack

• Astro 7 — static site generation, content collections via the content layer API
• Vue 3 — the few interactive islands (charts, radar)
• UnoCSS — atomic CSS, dark theme only
• MDX — posts and writeups
• Bun — package manager and runtime

Features

Built on top of the original Vitesse theme:

• 6 content collections — blog, infosec, ctf, musings, research, pages
• Auto OG images — a unique Open Graph image per page and per post, rendered with Satori
• View and like counters — serverless, talking straight to the Firestore REST API with no SDK and no API key
• Build freshness stamp — the footer shows the deployed commit and checks it against GitHub
• Self-hosted variable fonts — Google Sans Flex and Google Sans Code, so no external font requests
• Competition record — a table of CTF placements and rankings on the homepage
• Per-post lastmod for edited posts
• Extra pages — friends, gear, links, projects, and video
• Responsive — mobile-first, with tables that switch to a card layout on small screens
• Dark-only theme tuned for reading at night

Getting started

You need Bun and Node 24.x. npm and yarn are not supported.

bun install      # install dependencies
bun dev          # dev server on port 4321 (--host enabled)
bun run build    # production build
bun lint:fix     # auto-fix lint issues

Use bun run build, not bun build — the bare form runs Bun's own bundler instead of the build script.

Deployment

The site is static, so the build output in dist/ can be hosted anywhere. Dockerfile.vercel builds it with Bun and serves the static files, and is used for the Vercel deploy.
