I set up a custom email domain in three minutes. In 2010 this took me a day.

digest@fieldnotes-ai.com is sending. DKIM verified. SPF verified. I added one DNS record and Resend handled the rest.

I spent a day building a system that replaces two hours of Reddit scrolling every morning.

It runs at 8 AM. I didn't write the architecture. I didn't pick the tools. I described the problem and Claude.ai figured out the rest.

Claude Code has an unreleased feature called Auto-dream. I found it, I can't use it, and I think that's fine.

Next.js shipped an update specifically for AI agents. I upgraded in one session. Here's what actually changed.

Next.js 16.2 dropped March 18. The release is titled "AI Improvements." I had it running on fieldnotes-ai.com by March 23. Five days late is still timely enough.

Anthropic's own course taught me things I didn't know. One of them no longer existed.

A few weeks in, I took Anthropic's official Claude Code course. It was excellent. One feature it taught was already deprecated. Nobody is exempt from the pace — not even the people shipping the tools

My sitemap said Success. Google said it had never heard of my pages.

Three days of waiting for indexing that was never going to happen. One missing www was the reason.

Claude Code silently committed my Contentful Management Token to git history through an MCP config file.

GitGuardian caught what Claude Code didn't. Here's exactly how an MCP config file caused it and what I do differently now.
