Show HN: Hacker News em dash user leaderboard pre-ChatGPT (Score: 150+ in 9 hours)

Comments: https://readhacker.news/c/6AEnc
The use of the em dash (—) now raises suspicions that a text might have been AI-generated. Inspired by a suggestion from dang [1], I created a leaderboard of HN users according to how many of their posts before November 30, 2022—that is, before the release of ChatGPT—contained em dashes. Dang himself comes in number 2—by a very slim margin.
Credit to Claude Code for showing me how to search the HN database through Google BigQuery and for writing the HTML for the leaderboard.

Show HN: Vectorless RAG (❄️ Score: 150+ in 2 days)

Comments: https://readhacker.news/c/6Atha
Not all improvements come from adding complexity — sometimes it's about removing it.
PageIndex takes a different approach to RAG. Instead of relying on vector databases or artificial chunking, it builds a hierarchical tree structure from documents and uses reasoning-based tree search to locate the most relevant sections. This mirrors how humans approach reading: navigating through sections and context rather than matching embeddings.
As a result, the retrieval feels transparent, structured, and explainable. It moves RAG away from approximate "semantic vibes" and toward explicit reasoning about where information lives. That clarity can help teams trust outputs and debug workflows more effectively.
The broader implication is that retrieval doesn't need to scale endlessly in vectors to be powerful. By leaning on document structure and reasoning, it reminds us that efficiency and human-like logic can be just as transformative as raw horsepower.

I made a simple open-source letter editor inspired by Animal Crossing NH. Took me forever to look over each card, but I'm quite pleased with how it turned out. You can even click the bottle in the bottom right to see a random letter design shared by other users! Now to see how long it stays up...
