There are many SaaS tools that let users report bugs or submit feature requests. Did you know there was a Rails gem for this? `bundle add feedback-engine` & start receiving bug reports now: github.com/yshmarov/fee...

AI-translated your Rails app? Great. Now let users catch what it missed. Gem "i18n-feedback" lets a proofreader click any string in the running app and suggest a fix. Every suggestion is saved in the db. Devs / AI can evaluate and apply suggestions. The gem: github.com/yshmarov/i18...

Finally, I moved my last project from Heroku to Kamal+Hetzner. Over 11 years I paid $3970 for Heroku hobby projects Lately running ANY experiment app cost me ~$24/mo (webserver,postgres,worker). Now I'll be paying ~$5/mo per project for much more compute. More power. More freedom. More projects!

Creating extensions for simple_form is fun. There are a few JS input wrappers that I use a lot in my apps: - character counter - textarea autogrow - currency input mask PR adding character counter to simple_form: github.com/yshmarov/mon...

Deployed my first app via fly.io ! The estimated cost of web service + postgres + object storage (AWS S3 via @tigrisdata.com ) is ~$6/mo. Great CLI experience: "fly deploy" feels as good as "git push heroku master"

I do not like gem "rubocop-rails-omakase". I am not a fan of "gem "standard". I prefer sticking as much as possible to rubocop defaults. Rubocop teaches me new, better syntax. It takes max 30 minutes to configure cops from 0 based on your preferences & you learn a lot while doing so.

It's been many years since I last used gem "simple_form", but I kinda miss it. You define all the input type styling in a simple_form.rb file, and with minimal markup you can render consistently styled forms

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!
