2022 Ruby on Rails Community Survey Results— Over the past 13 years, Planet Argon has run several surveys like this. We encouraged you to take part, as usual, and the answers from 2660 folks (skewing heavily to long-time Rails developers) are now boiled down into the results:

• Devise is both the most loved and most frustrating gem!
• Ruby 2.7 remains the most popular Ruby version in use.
• GitHub Actions has become the most popular CI system on its first showing in the survey, pushing Circle CI down to #2.
• chruby remains the most popular Ruby version manager but the use of asdf is rapidly growing as RVM dips.
• Most Rails apps are not being updated to the latest version quickly.
• Remote working dominates and most dev teams have continued to get larger.

Mocktail: A Test Double Library with a Terse API for Creating Mocks— Mocktail has a simple API and offers detailed errors, argument matchers, and thread safety and Justin Searls did a five-minute lightning talk at RailsConf 2022 showing it off. The README is particularly thorough.

Quick Bits:

• ⚠️ Reader Ilya Demukh has written in to note that the most popular Ruby extension for VS Code hasn't seen a release in over a year and the author is actively looking for maintainers to help out.

• Rails has three new core members: Ryuta Kamizono (the 4th most prolific committer to Rails overall), Jean Boussier, and John Hawthorn. Yasuo Honda and Jonathan Hefner also join the Committers team.

• IDE developer JetBrains has opened the early access program for RubyMine 2022.2. Improvements have been made to the debugger for Ruby 3, RBS support continues to improve, and more.

• The first beta of Postgres 15 is out – I've written a quick walkthrough of trying it out quickly with Docker. If you're a Postgres user, check out our Postgres Weekly– it's an exciting time for Postgres and we share a lot there.

▶  How to Add a Command Palette to a Rails App— Have you ever pressed Cmd+K (or Ctrl+K) on GitHub and seen a box pop up that you can type commands into? It’s an interesting ‘power user’ feature and you can add a similar thing to your own apps. Chris uses Ninja Keys here, but kbar is another to consider.

📜  The Practical Effects of the GVL on Scaling in Ruby— This is from 2020 and the Ractors mentioned within are now a Ruby 3 core feature, but this meaty post on concurrency and parallelism came up in conversation recently and I still think it’s useful. There’s always a lock, it’s just a matter of where it’s implemented!
