Organic Test Driven Development in one file
I wrote about how I approach Test Driven Development in a very very lightweight manner at https://fly.io/ruby-dispatch/organic-test-driven-development/ by keeping gem dependencies, source code, unit tests, and documentation in a single file. This helps me keep iterations tight and rapid early on in a project. Once I’m ready to distribute it as a gem I break it apart into the usual files you’d see in a project.
Understanding the Ruby Global VM Lock by observing it
The Global VM Lock (GVL), is an implementation detail of the Ruby VM. At a high-level, it prevents code across multiple threads from running in parallel. The GVL can have a big impact on the performance and responsiveness of any application that uses more than a single thread to do its work. I’ve recently presented on this topic at RubyKaigi 2023; live interactive examples, the video, and slides are available at https://ivoanjo.me/blog/2023/07/23/understanding-the-ruby-global-vm-lock-by-observing-it/ .

New minitest-flash Gem for Your Fancy Red/Green Notifications
This just out: minitest-flash reporter – dull as ditchwater yet useful IMO. It simply calls your personal minitest-flash executable (usually a shell script) to trigger whatever fancy red/green notification you like. Safe to use on team projects as nothing happens unless the executable is present. The README showcases my setup for macOS which flashes the menu bar twice in either red or green along with an optional sound effect (mutable in case your ears have better things to do).

Every True Rubyist Builds Their Own Code Editor in Ruby!
Every self respecting Senior Software Engineer out there should build their own code editor, even if just as a toy app to later be discarded in favor of another code editor (though they might grow to prefer their own). And, if they are Rubyists, they should build their code editor in Ruby (whether using MRI Ruby, JRuby or Opal Ruby). If you think of yourself as a Ruby Senior Software Engineer, but cannot build your own code editor in Ruby, there are serious holes in your skillset!!
