What Hacker News says?
Given some of the ways Andre Arko gets described (See https://justin.searls.co/posts/why-im-not-rushing-to-take-si... for a recent overview) I'm a little wary of what the motivation behind this is.

HN discussionFor anyone who's ducked out of Rails World over the last decade (or two), I devoted my final conference talk last year to the topic of One-Person Framework with a real-world case study of how Rails 7+ specifically helps developers build ambitious apps, even as a solo developer. https://justin.searls.co/tubes/2024-11-09-11h03m00s/

HN discussionI love when friends do this. It's hard to keep up with people and what they're up to. Publishing and letting people subscribe to me is a great way to share things.

Turns out, it's the forest with the ancient moss and yakusugi trees from Princess Mononoke. Little did I realize that actually getting there is a pretty involved process, and it's a small mi…
