Show HN: Scala Tutorials – interactive Scala 3 lessons in the browser

A blast from the internet past just strutted back onto the scene: Scala Tutorials, a free, open-source site with tiny interactive lessons you can try right in your browser, no setup, no sign-in, no headache. But the real show wasn’t the tool itself — it was the comment section, where nostalgia, praise, and a mini identity crisis for Scala all collided at once.

The creator, eranation, dropped the ultimate comeback line: this started as a pet project back in 2013, then got revived for today with “a bit of help from Claude.” That little aside practically winks at the audience: old-school passion project meets new-school artificial intelligence assistant. Commenters were instantly supportive, with reactions like “Beautiful” and “Very nice!” giving the whole launch a warm, almost reunion-party vibe.

Then came the spicy part. One commenter said they used to love Scala 10 to 15 years ago but were shocked it seems to have so little buzz now, especially compared with Clojure, another programming language in the same general family. Translation for normal humans: they’re asking why this once-hyped tool now feels weirdly quiet. That turned a simple launch post into a subtle “Is Scala still cool?” debate. Another commenter chimed in to say they’d never even heard of Scastie, the browser tool powering the lessons, and casually plugged a similar Python project from earlier that day — a classic Hacker News move that felt equal parts networking, side quest, and gentle one-upmanship.
