RailsConf 2022 - Ruby Archaeology by Nick Schwaderer

In 2009 _why tweeted: "programming is rather thankless. you see your works become replaced by superior works in a year. unable to run at all in a few more." I take this as a call to action to run old code. In this talk we dig, together, through historical Ruby. We will have fun excavating interesting gems from the past. Further, I will answer the following questions: What code greater than 12 years old still runs in Ruby 3.1? What idioms have changed? And for the brave: how can you set up an environment to run Ruby 1.8 code from ~2008 on a modern machine?
