TLDR: you should add the frozen_string_literal comment for performance reasons
I was recently reminded that not everyone fully understand what the frozen string literal magic comment is about.
So I figured it was the occasion for another deep dive.

I'm trying HERB/ReActionView right now.
✅ UI for displaying HTML errors
✅ UI for debugging views
✅ HTML error warnings in IDE (with Code extension)
Really looking forward to auto-lint.
when adding RubyLLM to a Rails app, first of all I add:
- optional polymorphic relationship (Chat belongs to Post, User, Team)
- optional topic (Chat belongs to Post.title)
- status (check if the job is running)
If you're using friendly_id in Rails with Postgres, you should assign a slug_limit.
Otherwise sooner or later a long slug will create a PG::ProgramLimitExceeded: ERROR error
I have a very elegant Hotwire solution to this exact problem: superails.com/posts/ruby-on-…
Did Youtube thumbnail A/B testing for the first time.
A tiny difference in copy driving a large difference in performance.
I've recently implemented vector search in a Rails app.
It's great for searching by meaning, not keywords.
See 🖼️ how I search:
- "retreat", and the 1st (closest) result is a weekend trip
- "tshirt" -> tee
- "coach" -> "training sessions"
Super easy to implement!
You need:
- gem pgvector-ruby to enable vectors
- gem neighbor to search vectors
- gem rubyllm to encode texts and search queries

A year of work and it’s finally here!
Today I learned about github.com/charkost/prosopit… - an alternative to gem "bullet" for finding N+1 in a Rails app.
spent 4+ hours yesterday vibe coding some oauth stuff.
felt like my brain was rotting in this constant code review mode.
ended up rejecting everything & built the thing on my own in an hour.
feeling much better now.
calm down. everything is ok.
