From second part to first

After a few weeks off following my first concert back, I had my first rehearsal for the summer season with the community band this past Sunday. This time around I got moved up from second part to first part, which is a welcome challenge.

Redesigning (and migrating) my blog with Claude Code

A while back I wrote about migrating my blog from NextJS to Astro using GitHub Copilot. Well unfortunately that attempt stalled after 2 hours when the agent cornered itself in errors it couldn't resolve. I shelved it and moved on. Now in 2026, the ecosystem has matured greatly. Developers and nondevelopers alike are using models like Sonnet/Opus 4.5+ to migrate codebases and rapidly iterate on design in ways that simply weren't possible before.

Migrating to AstroJS from NextJS

I've been using the new Copilot agent mode to try to migrate my blog from NextJS App Router to Astro. I write all my blogposts in MDX with styling predefined via TailwindCSS. I then have a little legacy Webpack code that inserts getStaticProps calls where needed to fetch the blog data and then I decorate the post with a wrapper so that it looks consistent (probably should have moved a lot of this to a layout.tsx file, but you know how tech debt works).
