If you’re the Acting Ensign Crusher of Rails developers, you’ve probably heard about background jobs but are a little lost. They’re essential for building modern, responsive applications.

Yeah you did! Matching strings is easy, right up until it isn’t. Most programming languages give you a double-equals operator or maybe an eq method. We will focus on Ruby here.

For the last ten years or so of working on Bundler, I’ve had a wish rattling around: I want a better dependency manager. It doesn’t just manage your gems, it manages your ruby versions, too. It doesn’t just manage your ruby versions, it installs pre-compiled rubies so you don’t have to wait for ruby to compile from source every time. And more than all of that, it makes it completely trivial to run any script or tool written in ruby, even if that script or tool needs a different ruby t...| André.Arko.net

In two previous posts, I explained that one of the big blockers for Ractors’ viability is that while they’re supposed to run fully in parallel, in many cases, they’d perform worse than a single thread because there were numerous codepaths in the Ruby virtual machine and runtime that were still protected by the global VM lock.| byroot’s blog
