Down The Caching‑Hole? Adventures in 'HTTP Caching and Faraday' Land — It’s never good when you enable caching and performance gets worse. These cases often lead to long, forensic investigations that expose a previously unknown nuance and this case is no exception. “Off with their headers!”

Modernizing Einhorn: A Gem for Managing Forked Processes — Somehow I’d never come across Einhorn till now, but it started life as a Stripe-built gem for managing multiple copies of long-lived processes and now Sidekiq’s Mike Perham has inherited it (pretty much the biggest seal of approval a Ruby project could get) and taken it to a 1.0 release.

▶  A Rails Performance Guidebook: From 0 to 1B Requests Per Day — A senior engineer at Zendesk gave a talk at RailsConf 2022 reflecting on Zendesk’s use of Rails and a variety of high-level principles you can adopt when scaling your own apps (if not to the same level!) In related news, Zendesk is about to be acquired for $10.2bn. The most expensive Rails app ever? 😁

Quick Bits:

  • 🏆 TopRubyCompanies is a site that presents a table of well known companies (44 so far) known to be heavy Ruby users. While Zendesk (mentioned above) may be the biggest acquisition so far, it's only at #5 on this table.

  • It looks like direct support for common table expressions (CTEs) is coming to Active Record soon based on fresh activity on this PR from 2019.

  • Over ▶️ 60 talks from RailsConf 2022 are now available to watch on YouTube. We're still watching them and will feature some of our favorites next week.

'Booleans Don't Exist in Ruby' — Sure, true and false exist and work well as high level representations, but under the hood, a lot is going on. Mike digs into a variety of areas to learn more including object identifiers, Ruby’s C underpinnings, and what third party libraries do.

A Rubyist's Guide to ViteVite is the (another) latest shiny toy in JavaScript and frontend build tooling (but, to be fair, it’s pretty amazing). It uses ES module imports, it’s fast and setting it up with Rails is pretty easy thanks to some gems including vite_ruby/rails. (Note: This article dates from 2021, but Vite seems to be going from strength to strength lately, and Vite 3.0 just came out.)

▶  Turbo Frames vs. Turbo Streams — When he was first introduced to Turbo Frames and Turbo Streams, Cezar couldn’t quite figure out the differences (though there are many). Now he has, and deftly explains in this video when to pick one over the other. (Eight minutes.)

SearchCop: Search Engine-Like Query Support for Active Record — Adds support for an easy to use search interface on top of AR models. It’s smarter than you might imagine and can handle using operators to query against columns – it’s not just for text. Can’t help but think I’d like to see some of these ideas become standard AR features!

Casting 1.0: Delegate Methods in Ruby and Preserve self“Casting gives you real delegation that flattens your object structure compared to libraries like Delegate or Forwardable. With casting, you can implement your own decorators that will be so much simpler than using wrappers.”
